Tool clamping apparatus is the important segment of stand or fall of quality of product of immediate impact crankshaft and manufacturing cycle accident. Reach norms to satisfy crankshaft product breed, series the requirement of ceaseless grow in quantity, development of limited company of overhead profit crankshaft gives pneumatic clamp unit, it is assembled not only convenient, make mix simply clamp rate is rapid, and the production of OK and economic clamping apparatus prepares cycle, improve productivity effectively, reduce manufacturing cost. Technical setting makes a process in the production of crankshaft in, tool clamping apparatus is quality of immediate impact product and the important segment that produce cycle. E.g. , undertake drilling oily hole to neck of crankshaft main shaft and connecting rod neck, its machine need to part to match clamping apparatus of a bore to divide working procedure to finish each on two radial drilling machine, so every kinds of crankshaft needs two clamping apparatus, not only versatility is poor, and cycle of tall, production grows the production cost that still causes clamping apparatus, the frequency that hold clip much, efficiency is low. Accordingly, the technical personnel of my company expects to use a kind of structure all the time reasonable, assemble convenient, make the clamp device with rapid rate of simple, clamp. Graph unit of 1 crankshaft clamping apparatus is current, prejudicial annulus or helix clamp orgnaization is the orgnaization of a kind of clamp with more application. Prejudicial operation of round of clamp orgnaization treatment convenient, clamp is rapid, defect is clamping force and clamp journey small; Simple, clamp mixes structure of helix clamp orgnaization reliably versatility is good, and because helix promotes role small, of helix clamp orgnaization good from lock function, clamping force and clamp distance are greater, defect is the hand moves clamp, clamp movement strength of slow, labor is great. To overcome afore-mentioned inadequacy, we begin to develop pneumatic clamp device by oneself. Nextpage plan set 1.

Overall train of thought asks to make technology according to the product, define included angle, clamping force and clamp journey scope, the design gives a kind of structure reasonable, assemble convenient, create simple, fixed position speed of accurate, clamp is mixed quickly labor intensity is low, applicable all sorts of axes kind the pneumatic clamp device of clamp. 2.

Adoption principle machines precision and existing equipment requirement according to what the product asks, according to clamping apparatus design principle devises the way that hold clip, undertake by fixed position fundamental clamping apparatus fixed position is analysed, analyse the fixed position error when computation locates, design the plant of pneumatic clamp certainly thereby. Graph device of clamp of pneumatic of device of 2 pneumatic clamp includes: Clamping apparatus body, bearing, lever of air cylinder, piston, pressing plate and bolster plate. Bearing installation is on clamping apparatus body, with will put crankshaft spare parts and other treatment unit. Bolster plate can change by level and perpendicular direction installation is in bearing on, according to different crankshaft diameter measurement, change ply is different can change bolster plate, hold the central position with neck of crankshaft main shaft or connecting rod appropriate neck, the treatment of facilitating crankshaft. For example, the treatment of aperture of straight oil of the main shaft neck of crankshaft or connecting rod neck, its feature depends on bearing front installs an annular bolt, pressing plate bottom sells installation to be on annular bolt through hinge, pressing plate upside sets aperture of two chief body, lever front inserts the piston to grow form aperture among them, both with slip annul be linked together; What narrate air cylinder to receive an installation to be on clamping apparatus body through in succession, bearing on set via, the piston lever of air cylinder crosses bearing via, below the action of move back and forth of air cylinder, piston lever drives the slip pressing plate that sell an edge to grow form aperture to move, pressing plate circles the hinge that annular bolt props up to sell roll, upside impaction or loose spare parts. The orthogonality on direction of Kong Chuizhi of two on pressing plate chief body, piston lever makes linear shift, the slip pressing plate selling an edge of its front the chief body aperture of two orthogonality is mobile. Annular bolt installation is in bearing whorl Kong Zhong, annular bolt is exterior still set nut of a fixed position, both cooperates to come back, can adjust fixed position of annular bolt extend length, differ in order to suit pressing plate clamp diametical spare parts. The technology innovates 1.

Bearing front installs an annular bolt, its are annular bolt installation is in bearing whorl Kong Zhong, annular bolt is exterior set nut of a fixed position, both cooperates to come back, can adjust fixed position of annular bolt extend length, differ in order to suit pressing plate clamp diametical spare parts. 2.

Pressing plate bottom sells installation to be on annular bolt through hinge, pressing plate is OK hinge is sold for the centre of a circle, make whirligig. Pressing plate upside sets aperture of two chief body, the orthogonality on direction of Kong Chuizhi of two on pressing plate chief body, horizontal way inserts piston lever front to grow form Kong Zhong among them, in aperture of another chief body pressing plate and piston lever are used slip annul be linked together, pressing plate and piston lever establish ties. Piston lever makes linear shift, of its front slip sell but along pressing plate the chief body aperture of two orthogonality moves. 3.

Air cylinder installation is received in in succession on, join an installation go up in clamping apparatus body. Join can change, use connection the air cylinder of different diameter or oil cylinder, do not suffer bearing the influence of size. Bearing one via is set on horizontal way, the piston lever of air cylinder crosses bearing via, can direct inside its mobile, below the action of move back and forth of air cylinder, piston lever drives the slip pressing plate that sell an edge the chief body aperture of two orthogonality is mobile, pressing plate bottom circles hinge to sell roll, thereby impaction of pressing plate upside or loose spare parts. Executive effect gets stuck serious check of my company production, gently and car crankshaft 50 many model, the product of every model matched a clamping apparatus in the past (some needing that match 2 clamping apparatus) , every kinds of product matchs a clamping apparatus now, improved speed of product research and development and labor productivity, the production that saved clamping apparatus prepares cycle, reduced manufacturing cost. Operating costs of a clamping apparatus about 5000 yuan, by save 50 clamping apparatus to calculate, will be a company managing 250 thousand yuan. CNC Milling
