Detailed description of the invention
Be described in detail to characteristic sum principle of the present utility model below in conjunction with accompanying drawing 1-Fig. 6, illustrated embodiment, only for explaining the utility model, not limits protection domain of the present utility model with this.
As shown in Figure 1 and Figure 2, this utility model comprises bent axle fixed head 1, depression bar 2, top end, lower top 4, support and containment vessel 8.Wherein base 7 is a flat board, is fixed by screws on lathe.Above base 7, be fixed with two parallel bearing side plates by screw, the top of bearing side plate is provided with dive key 11, is connected with the bottom dive key keyway 19 of rack plate 5.Form a space between two bearing side plates and bearing bottom upper plate, in this space, be placed with the cylinder 12 driving depression bar 2, farthest decrease the volume that this fixture takies.
Described bearing top board is a flat board, and bearing top board is fixed with bent axle fixed head 1, and described bent axle fixed head 1 is a flat board.Bent axle fixed head 1 laterally has the V-type groove 9 and top end installing hole 10 that penetrate bent axle fixed head 1.One end of top end installing hole 10 is communicated with V-type groove 9 openend, the other end then penetrates bent axle fixed head 1 and is in communication with the outside, top end penetrates into from one end that top end installing hole 10 is in communication with the outside in bent axle fixed head 1 and contacts with crank section 14 outer circumference surface of bent axle 17, realizes the clamping to bent axle 17.
As shown in Fig. 3, Fig. 4, Fig. 5, one end of top end penetrates in top end installing hole 10, and the other end contacts with depression bar 2, contacts with the steady of depression bar 2 to realize top end, one end that top end contacts with depression bar 2 can be designed to dome shape.Top end is equipped with elastic component, and elastic component is between top end and bent axle fixed head 1.When depression bar 2 promote top end move in top end installing hole 10 time, elastic component is compressed, and realizes the clamping to bent axle 17; After machining, depression bar 2 discharges the promotion to top end, and elastic component is flexible to be ejected top end, and top end stretches out the one end in top end installing hole 10 and is separated with the crank section 14 of bent axle, realizes unclamping workpiece.
Described elastic component can be ripple spring 16.
Described depression bar 2 top is hinged by straight pin 13 and rack plate 5, outside straight pin 13, be equipped with sleeve, and reduce the friction of depression bar 2 and straight pin 13, depression bar 2 can rotate around this straight pin 13.The bottom of depression bar 2 is connected with the piston rod of cylinder by lower top 4, and lower one end of top 4 is fixedly connected with the piston rod of cylinder, and the other end contacts with the bottom of depression bar 2.Be connected with the stable of depression bar 2 to realize lower top 4, one end that lower top 4 contacts with depression bar 2 is designed to dome shape.Described cylinder 12 is fixedly mounted between base 7 liang of parallel bracket side plates 6 by cylinder holder.
Be provided with containment vessel 8 outside described support, the top of containment vessel 8 is fixedly connected with bent axle fixed head 1 by screw, and bottom is fixedly connected with base 7.Each parts of containment vessel 8 pairs of fixtures serve the effect of protection.
The use procedure of this fixture is as follows:
Composition graphs 1 to Fig. 6, is inserted laterally in the V-type groove 9 on bent axle fixed head 1 by the crank section 14 of bent axle, be adjacent to the end face of crank rod and the side of bent axle fixed head 1, and the side of this bent axle fixed head 1 is as the axial locating surface of bent axle 17.The position of keyway 18 to be processed is in the side of crank section 14 outer circumference surface of bent axle, and keyway 18 Working position stretches out outside bent axle fixed head 1, as shown in Figure 6.Wherein the pore of bent axle realizes the location with bent axle fixed head 1 by alignment pin 15.After inserting bent axle, Digit Control Machine Tool is stretched out by control cylinder piston rod, lower top 4 is driven to rotate with contacting bottom depression bar 2 and promote depression bar 2 around straight pin 13, the promotion top end compressional wave spring 16 of depression bar 2 moves in top end installing hole 10 simultaneously, top end stretches into top end installing hole 10 one end fits V-type groove 9 and is compressed by the crank section 14 of bent axle, realizes the radial clamping of bent axle.After the keyway 18 of bent axle machines, Digit Control Machine Tool control cylinder piston rod shrinks, retract in lower top 4 thereupon, depression bar 2 rotates backward around straight pin 13, top end ejects certain distance under the elastic reaction of ripple spring 16, top end is separated with the crank section 14 of bent axle, and then manipulator has taken bent axle away blanking.
Bent axle fixed head 1, top end and rack plate 5 integrally, when needing the size changing bent axle to be processed, the straight pin 13 connecting depression bar 2 is only needed to take off, then the dive key 11 that rack plate 5 coordinates with rack side plate 6 bottom rack plate 5 together with top end and bent axle fixed head 1 is taken off, use the bent axle fixed head 1 corresponding with Crankshaft Sizes to be processed instead, and need not with parts such as the seat 7 that refoots, depression bar 2, cylinders, this just makes this fixture have good versatility.The utility model adopts dive key 11 to achieve the part quick-replaceable of fixture, and achieve fixture with centering when changing, having saved a lot of time when changing the bent axle of different model, having improve working (machining) efficiency, and dive key 11 makes must facilitate with transformation.
Above-described embodiment is only the description carried out preferred embodiment of the present utility model; not scope of the present invention is limited; under the prerequisite not departing from the utility model design spirit; relevant technical staff in the field, to various distortion of the present utility model and improvement, all should expand in the determined protection domain of the utility model claims.
