[0045] The shift clamping unit 300 includes a carrier plate 301, which is mounted on the surface of the operating table 101. A positioning platform 302 is mounted on one side of the carrier plate 301. The side walls of the positioning platform 302 are respectively connected to the conveying track 104. A clamping plate 303 is slidably arranged on the positioning platform 302, and the clamping plate 303 corresponds to the outlet of the conveying track 104 on the gasket oscillating feed tray body 103. A top plate 3032 is mounted on the bottom of the clamping plate 303, and the top plate 3032 corresponds to the outlet of the conveying track 104 on the bolt oscillating feed tray body 102. Should, a pressure plate 304 is vertically inserted on the bearing plate 301, and the pressure plate 304 is movably connected to a fixed platform 3012 fixed on the surface of the bearing plate 301, and two pairs of clamping columns 3041 are installed on the pressure plate 304, and a clamping block 305 is slidably arranged inside the clamping column 3041, and a blocking block 3051 is installed at the bottom of the clamping block 305, and a gap is left between the blocking block 3051 and the pressure plate 304, and a compression spring 3063 is clamped between the clamping block 305 and the fixed platform 3012, and the distance between the two clamping blocks 305 is less than the diameter of the gasket;

[0046] The stamping feeding unit 200 includes a protective cover 201, which is placed above the supporting plate 301, and a special-shaped turntable 202 is rotatably installed inside the protective cover 201, a driving motor 2022 is installed at the rotation center of the special-shaped turntable 202, a rocker arm 203 is installed at the eccentric position of the special-shaped turntable 202, a stamping seat 2032 is installed at the end of the rocker arm 203, and the stamping seat 2032 movably penetrates the protective cover 201, a cylindrical electromagnet 2033 is movably inserted at the bottom of the stamping seat 2032, a protrusion 204 is installed on the side wall of the special-shaped turntable 202, a synchronous bracket 2043 is slidably arranged on the side wall of the special-shaped turntable 202, the synchronous bracket 2043 movably penetrates the protective cover 201, and the end of the synchronous bracket 2043 is connected to the top plate 3032.

[0058] The present invention also discloses a stamping process of a bolt washer stamping device, the steps of which are as follows:

[0059] Step 1: Put bolts and washers of matching specifications into the bolt oscillating feeding tray body 102 and the washer oscillating feeding tray body 103, and transport the raw materials to the positioning table 302 through the conveying track 104;

[0060] Step 2: Start the driving motor 2022, and drive the special-shaped turntable 202 to rotate through the driving motor 2022, and the position of the protrusion 204 on the special-shaped turntable 202 changes, and the protrusion 204 drives the synchronous bracket 2043 to move left and right, and the synchronous bracket 2043 pushes the top plate 3032 at the bottom to slide;

[0061] Step 3: During the sliding of the top plate 3032, the end surface of the top plate 3032 pushes the bolt to move, and the clamping plate 303 pushes the washer to slide synchronously.

When reset, the cylindrical electromagnet 2033 absorbs the processed workpiece, and the gasket and the bolt are unlocked synchronously. At this time, the processed workpiece is absorbed and moves upward, and is moved out of the processing workstation to facilitate later unloading.

[0064] The implementation principle of a bolt and washer stamping equipment and its process of the present embodiment is as follows: bolts and washers of appropriate specifications are placed into the bolt oscillation feed tray body 102 and the washer oscillation feed tray body 103, and bolts and washers can be input one by one into the conveying track 104 through the bolt oscillation feed tray body 102 and the washer oscillation feed tray body 103, wherein the bolt oscillation feed tray body 102 and the washer oscillation feed tray body 103 are existing technologies, and their working principles will not be repeated here.

[0065] When the washers and bolts are transported along the transport track 104 , the bolts at the end of the transport track 104 will move to the front of the top plate 3032 , and the washers will move to the clamping groove 3031 of the clamping plate 303 .

[0066] First, the operator can start the driving motor 2022, and the driving motor 2022 drives the rotating shaft 2021 at the end of the output shaft to start rotating, and the rotating shaft 2021 is installed with the special-shaped rotating disk 202, so that the special-shaped rotating disk 202 starts to rotate counterclockwise (in degrees). Figure 3 As a reference), the special-shaped turntable 202 and the protrusion 204 can rotate synchronously, wherein the positions of the guide grooves 2041 on the surfaces of the special-shaped turntable 202 and the protrusion 204 change, and when the protrusion 204 moves to the side wall of the guide slider 2042, the entire guide slider 2042 slides outward, and the synchronous bracket 2043 on the guide slider 2042 slides synchronously, and the synchronous bracket 2043 can drive the positioning slider 2044 to slide inside the positioning groove 2045, and the reset rod 2051 on the side wall of the synchronous bracket 2043 is inserted into the reset cover 205, wherein when the reset rod 2051 slides, the reset rod 2051 drives the baffle 2052 to slide, and the baffle 2052 can squeeze the reset spring 2053 for compression, and reset by the reset spring 2053.

[0067] When the synchronous bracket 2043 slides back and forth, the synchronous bracket 2043 can push the top plate 3032 to slide. In the process of the top plate 3032 sliding, the end surface of the top plate 3032 pushes the bolt to move, and the clamping plate 303 pushes the washer to slide synchronously. When the washer moves, the washer will squeeze the clamping block 305 to move to both sides. At this time, the moving slider 306 slides on the moving slide groove 3061, and the compression spring 3063 on the moving rod 3062 is compressed synchronously. The clamping block 305 at this time has a clamping force on the washer, so when resetting, the clamping block 305 will squeeze and fix the washer, but the clamping plate 303 can retract by itself without affecting the washer. When the top plate 3032 pushes the bolt to slide, the bolt will be clamped under the blocking block 3051 to ensure that the bolt and the gasket move to the specified position, and when the clamping plate 303 is reset, it will not push the bolt and the gasket to move, ensuring that the corresponding position will not change.

[0068] During the process of the protrusion 204 sliding toward the synchronous bracket 2043, the special-shaped turntable 202 is rotating, and the eccentric position of the special-shaped turntable 202 can drive the rocker arm 203 to change, and the connecting block 2031 at the end of the rocker arm 203 can drive the entire stamping seat 2032 to slide downward, and the stamping seat 2032 squeezes the washer that has moved to the specified position and moves it toward the bolt, so that the washer is stamped on the bolt, and the fixed platform 3012 at this time mainly serves the purpose of positioning.

[0069] When the stamping seat 2032 slides downward, the slide plate 2034 on the side wall of the stamping seat 2032 slides on the positioning rod 2035, and the positioning rod 2035 is used to limit the position, and the positioning spring 2037 on the positioning rod 2035 is compressed during the sliding process. The positioning spring 2037 facilitates the subsequent resetting operation, and the positioning plate 2036 ensures that the positioning rod 2035 and the slide plate 2034 will not separate.

[0070] When the punching seat 2032 moves downward, the punching seat 2032 will first squeeze the first inclined surface 3052 of the side wall of the clamping block 305, and then push the clamping block 305 to move to both sides to complete the unlocking of the gasket. However, at this time, the cylindrical electromagnet 2033 at the bottom of the punching seat 2032 will absorb the gasket and drive the gasket to continue to slide downward to ensure that the gasket and the bolt can correspond to each other. When the punching seat 2032 slides downward, the punching seat 2032 will also push the entire pressing plate 304 to slide downward synchronously. At this time, the clamping column 3041 on the pressing plate 304 slides on the clamping rod 3043, and the guide spring 3045 is compressed, which is convenient for later resetting through the guide spring 3045. When the pressing plate 304 slides downward, it can also drive the blocking block 3 051 slides downward, the second inclined surface 3053 on the blocking block 3051 contacts the bottom of the bolt, and is then affected by the extrusion force. At this time, the blocking block 3051 moves to both sides, the blocking block 3051 and the bolt are separated and unlocked, and finally the stamping operation is completed. When the stamping seat 2032 is reset, the cylindrical electromagnet 2033 adsorbs the processed workpiece, and the gasket and the bolt are unlocked synchronously. At this time, the processed workpiece is adsorbed and moves upward, and is moved out of the processing station to facilitate subsequent unloading. When the subsequent clamping plate 303 and guide plate 3033 move to the bottom of the stamping seat 2032, the cylindrical electromagnet 2033 is powered off, and the workpiece falls onto the guide plate 3033 and is guided to the specified position by the inclined guide plate 3033.
