Description

A kind of flexible quick-speed jigs device
Technical field
What the present invention relates to is that special fixture is used in a kind of crankshaft end structure processing, especially a kind of flexible quick-speed jigs device of crankshaft end structure processing usefulness.
Background technology
Fig. 1,2 is depicted as a kind of crankshaft end structure processing of exploitation of Taiwan company and application and uses special fixture; It includes a workbench 11; Two base plates 13 about being equipped with through slide rail 12 on the workbench 11; One V-type support 14 respectively is installed, and with the crank throw axle journal of this V-type support 14 location bent axles 15 on the base plate 13, above said crank throw axle journal with the end clamping of a swing pressing plate 16; The other end of said swing pressing plate 16 links to each other with support bar 17 on being fixed on base plate 13; The centre of swing pressing plate 16 is connected with an oil cylinder 18; This oil cylinder 18 is installed on the cylinder pedestal 19 on the base plate 13, and the centre of bent axle 15 also adopts V-block to realize assist location and clamping.The special fixture of said structure is to locate at crank throw axle journal place through the V-type support 14 of crankshaft two end; The poor stability of therefore locating in the clamping process; When the middle V-block of bent axle 15 upwards withstands the crank throw axle journal; Had positioning phenomenon, the excessive crankshaft deformation that causes easily of clamping force does not too smallly have an assist location effect.These anchor clamps need twice clamping, the inefficiency of anchor clamps.In addition, these anchor clamps can not be used for the bent axle of different size to be processed, and when changing product, needs to change corresponding anchor clamps, has increased the cost and production preparatory period of technological equipment.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, and the good stability of locating in a kind of clamping process is provided, positioning accuracy is high, the flexible quick-speed jigs device of high efficiency.
The objective of the invention is to accomplish through following technical scheme; It includes a base plate; A rail brackets is respectively arranged about base plate, through guide rail is individual a planker is installed on it, the V-block of the pivoting support axle journal of a location bent axle is respectively arranged on the planker; Clamp with the angling cylinder press plate mechanism on the pivoting support axle journal of bent axle, the crank throw side in the middle of the bent axle is provided with a self-centering unit and the crank throw both sides is clamped to realize assist location.
Described angling cylinder press plate mechanism include one be pressed in bent axle pivoting support axle journal top board, described cylinder pedestal is fixed in through an adjusting screw in an end of pressing plate, and be equipped with on the said cylinder pedestal one with pressing plate in the middle of the oil cylinder that links to each other.
Described self-centering unit includes the middle guide rail that is installed on the base plate, on this middle guide rail, is connected with the intermediate support that a pair of crank throw side carries out assist location through a knee-piece oil cylinder.
The left and right sides is separately installed with a motor on the described base plate, and said motor passes the planker of side separately through screw mandrel and links to each other with the support of bearing on the side base plate.
Anchor clamps of the present invention have higher flexibility; The locating clip at two ends is promptly purchased module can make servo motion on clamp body, when the product processed specifications vary, only need to get final product through the axial location of program adjustment two ends positioning and clamping mechanism module; When greatly having simplified the product conversion; The adjustment of technological equipment has improved the precision of adjustment, has shortened the production preparatory period.

The specific embodiment
To combine below accompanying drawing to the present invention make detailed introduction: Fig. 3,4, shown in 5; The present invention mainly includes a base plate 21; A rail brackets 22 is respectively arranged about base plate 21; Through guide rail 23 planker 24 is installed respectively on it; The V-block 26 of the pivoting support axle journal of one location bent axle 25 is respectively arranged on the planker 24, clamp with the angling cylinder press plate mechanism on the pivoting support axle journal of bent axle, the crank throw side in the middle of the bent axle 25 is provided with a self-centering unit and the crank throw both sides is clamped to realize assist location.
Angling cylinder press plate mechanism shown in Figure 4 include one be pressed in bent axle pivoting support axle journal top board 27; Described cylinder pedestal 29 is fixed in through an adjusting screw 28 in one end of pressing plate 27, and be equipped with on the said cylinder pedestal 29 one with pressing plate 27 in the middle of the oil cylinders 30 that link to each other.
Described self-centering unit includes the middle guide rail 31 that is installed on the base plate 21, on this middle guide rail 31, is connected with the intermediate support 33 that a pair of crank throw side carries out assist location through a knee-piece oil cylinder 32.
Shown in Figure 5, the left and right sides is separately installed with a motor 34 on the described base plate 21, and said motor 34 passes the planker 24 of side separately through screw mandrel 35 and links to each other with the support of bearing 36 on the side base plate.
Anchor clamps of the present invention are realized main location at crank up axle journal place, position stability is good in the clamping process, and there was not positioning phenomenon in middle side location of adopting self-centering unit at crank throw, and positioning accuracy is high.The clamping of said anchor clamps and assist location are once accomplished automatically, high efficiency.
