Detailed Description

Referring to fig. 1, the present invention provides a technical solution: a punching device for an axle rear cover comprises an Contraband-type bracket 1, a hydraulic push rod 2 is fixedly connected to the upper surface of the Contraband-type bracket 1, the lower end of a telescopic rod of the hydraulic push rod 2 penetrates through the lower surface of a transverse plate on the upper side of the Contraband-type bracket 1 in a sliding manner, a punching head 3 is fixedly connected to the lower end of the telescopic rod of the hydraulic push rod 2, a bearing plate 4 is fixedly connected to the upper surface of the transverse plate on the lower side of the Contraband-type bracket 1, a supporting block 5 which is in the same vertical position with the punching head 3 is arranged on the upper surface of the bearing plate 4, meanwhile, the structure of the supporting block 5 is hemispherical, the upper surface of the supporting block 5 is provided with a stamping groove 6 matched with the stamping head 3, therefore, by placing the rear cover of the vehicle axle on the supporting block 5, the hydraulic push rod 2 pushes the stamping head 3 to stamp the rear cover of the vehicle axle, so that the punching head 3 penetrates into the punching groove 6, thereby achieving the effect of punching the axle rear cover.

Through setting up the structure of supporting shoe 5 to hemispherical in this embodiment, make lid inner wall form behind the surface of supporting shoe 5 and the axle like this and support, the sunken condition can not appear in lid behind the axle when lid punching press behind the axle to punching press head 3 like this, has further ensured the lid quality after punching a hole behind the axle, has reduced the incomplete volume after the lid punches a hole behind the axle.

Adopt detachable construction installation between supporting shoe 5 and the loading board 4 in this embodiment, the later stage of being convenient for like this changes the supporting shoe 5 of different diameters size, consequently makes the device be applicable to not the axle rear cover of equidimension and punches a hole processing.

Please refer to fig. 2, sliding connection has rebounding plate 7 in punching groove 6, fixedly connected with spring 8 between rebounding plate 7's the lower surface and the 6 diapalls of punching groove 6, consequently, form decurrent thrust to rebounding plate 7 when punching head 3 extends into punching groove 6, make rebounding plate 7 extrude spring 8, upward displacement and extend punching groove 6 and the circular incomplete piece on the punching head 3 drops to punching groove 6 when punching head 3, rebounding plate 7 pushes out punching groove 6 with circular incomplete piece under spring 8's resilience effect, the staff of being convenient for through this kind of mode collects circular incomplete piece, the operating difficulty when further having reduced the staff and collecting circular incomplete piece, the efficiency of when having improved lid punching a hole and processing the axle after.

Referring to fig. 3-4, the upper surface of the bearing plate 4 is provided with two arc-shaped fixing plates 9 which are arranged in a mirror image manner and are respectively located at two sides of the supporting block 5, and the surface of one side of each of the two arc-shaped fixing plates 9 opposite to the other side is fixedly connected with two connecting sliders 10, so that the outer surface of the axle rear cover is fixed through the two arc-shaped fixing plates 9, the problem that the axle rear cover deviates in the punching process is avoided, the stability of the axle rear cover in the punching process is further improved, and the precision of the axle rear cover after punching is ensured.

Furthermore, a built-in control cavity 11 is formed in the bearing plate 4, two connecting sliding grooves 12 which are communicated with the built-in control cavity 11 are formed in the upper surface of the bearing plate 4, the lower sides of the two connecting sliding blocks 10 extend into the built-in control cavity 11 through the two connecting sliding grooves 12 respectively, and the connecting sliding blocks 10 are connected with the inner walls of the connecting sliding grooves 12 in a sliding mode.

Further, the side of loading board 4 is provided with rotating head 13, rotating head 13 rotates to run through in built-in control chamber 11 and finally rotates the screw rod 14 of connection on built-in control chamber 11 inner wall towards fixedly connected with on the surface of one side of loading board 4, screw rod 14 is located the one end surface in built-in control chamber 11 and has cup jointed threaded sleeve 15 in the screw thread, threaded sleeve 15's surface and link block 10 rotate towards between the screw rod 14 and be connected with connection push pedal 16, consequently, through rotating head 13, make threaded sleeve 15 carry out the displacement under screw rod 14's transmission, make connection push pedal 16 form thrust or pulling force to link block 10 like this, thereby make two arc fixed plates 9 carry out relative direction or opposite direction displacement respectively like this.

Further, all seted up restriction spout 17 on the relative both sides inner wall of connection spout 12, slider 10 towards restriction spout 17 one side on the surface fixedly connected with restriction spout 17 sliding connection's restriction slider 18, restriction slider 18 slides in restriction spout 17 in step when slider 10 displacement like this, the condition that arc fixed plate 9 appears inclining when having avoided connecting push pedal 16 to promote slider 10 to carry out the displacement by restriction slider 18 like this, the dead condition of card has further been prevented to appear between arc fixed plate 9 and the loading board 4 upper surface, smoothness and stability when having ensured arc fixed plate 9 displacement.

The working principle is as follows: when being used for lid behind the axle to use punching device, hydraulic pressure push rod 2 promotes punching press head 3 and carries out the punching press to lid behind the axle, make punching press head 3 penetrate in punching press groove 6, form decurrent thrust to rebound board 7 simultaneously, make rebound board 7 extrude spring 8, upwards displacement and extend punching press groove 6 and the circular incomplete piece on the punching press head 3 drops to punching press inslot 6 when punching press head 3, rebound board 7 is released punching press groove 6 with circular incomplete piece under spring 8's resilience effect.
