[0033] Reference Figure 1 and Figure 2 The positioning assembly 7 includes a clamping plate 71, and the clamping plate 71 is provided with four groups. The bottom of the clamping plate 71 is fixedly connected with a connecting block 78, and the connecting block 78 is provided with four groups. The clamping plate 71 is driven to move by the moving effect of the connecting block 78. The bottom of the connecting block 78 is hinged with a hinged rod 73, and the hinged rod 73 is provided with four groups. The moving effect of the hinged rod 73 drives the connecting block 78 to move. The bottom end of the hinged rod 73 is hinged with a disc 74, and the vertical movement effect of the disc 74 drives the four groups of hinged rods 73 to move at the same time. A slide groove 72 is opened on the top of the workbench 1, and the slide groove 72 is provided with four groups.

[0034] Reference Figure 3 and Figure 4 The assembly and disassembly component 8 includes a collar 81, and a round block 82 is inserted into the inner wall of the collar 81. The pressure head 4 can be installed through the insertion effect of the collar 81 and the round block 82. The front inner wall of the round block 82 is elastically connected with a wedge block 83 through a spring 84. Through the elastic force of the spring 84, the wedge block 83 always maintains a clamping effect with the slot when not affected by external force, thereby limiting the round block 82. A slot is provided on the front of the collar 81.

[0035] Reference Figure 2 The outer wall of the clamping plate 71 is slidably connected to the inner wall of the slide groove 72. The sliding effect of the clamping plate 71 clamps and positions the workpiece on all sides. The bottom of the disc 74 is fixedly connected to a cylindrical rod 75. The vertical movement effect of the cylindrical rod 75 drives the disc 74 to move vertically. The front bottom end of the cylindrical rod 75 is hinged with a telescopic rod 76. The telescopic rod 76 is formed by two sets of sleeve rods connected to each other, and has the effect of extension and contraction.

[0036] Reference Figure 3 and Figure 4 The top of the collar 81 is fixedly connected to the output end of the hydraulic cylinder 3, and the collar 81 is prevented from falling off by the fixing effect of the collar 81. The bottom of the round block 82 is fixedly connected to the top of the pressure head 4, and the pressure head 4 is prevented from falling off by the fixing effect of the pressure head 4. The right inner wall of the collar 81 passes through and is threadedly connected with a bolt 85. One end of the spring 84 is fixedly connected to the front inner wall of the round block 82, and the other end of the spring 84 is fixedly connected to the outer wall of the wedge block 83. The fixing effect of the spring 84 keeps the wedge block 83 fixed to prevent the wedge block 83 from falling off.

[0037] Reference Figure 2 The outer wall of the telescopic rod 76 is hinged to the inner wall of the front side of the workbench 1. Through the hinge effect of the telescopic rod 76, the telescopic rod 76 can rotate, thereby driving the cylindrical rod 75 to move vertically. The front end of the telescopic rod 76 is fixedly connected to a pedal 77, and the staff presses the pedal 77 to facilitate the rotation of the telescopic rod 76.

[0038] Reference Figure 4 A threaded hole is provided on the right side of the round block 82, and two groups of threaded holes and bolts 85 are symmetrically distributed. The outer wall of the bolt 85 is threadedly connected to the inner wall of the threaded hole. By threading the bolt 85 to the threaded hole, the fixing effect of the round block 82 and the pressure head 4 is improved. The outer wall of the wedge block 83 is slidably connected to the inner wall of the front face of the round block 82. Through the sliding effect of the wedge block 83, the wedge block 83 is engaged with or released from the slot. The outer wall of the wedge block 83 is engaged with the inner wall of the slot. Through the engaging effect of the wedge block 83 and the slot, the ring 81 limits the round block 82.

[0039] Working principle: When the staff needs to perform spinning processing on the workpiece, the staff places the workpiece on the top of the rotating shaft 5 and presses the pedal 77. The pedal 77 drives the telescopic rod 76 to rotate downward, so that the cylindrical rod 75 moves upward, drives the disc 74 to move upward, and drives the four groups of hinged rods 73 to move through the disc 74 at the same time. The four groups of hinged rods 73 drive the four groups of connecting blocks 78 to move, so that the four groups of clamping plates 71 slide along the inner walls of the four groups of slide grooves 72 toward the rotating shaft 5, thereby clamping and positioning the workpiece.

[0040] After the four groups of clamping plates 71 clamp the workpiece, the staff starts the hydraulic cylinder 3 to drive the ring 81 and the round block 82 to move downward, so that the pressure head 4 moves downward, and the workpiece is pressed and fixed by the pressure head 4 and the rotating shaft 5. At this time, the pedal 77 is released to make the disc 74 move downward under the action of its own gravity, so that the four groups of clamping plates 71 release the clamping effect on the workpiece, and the motor 6 is started to drive the rotating shaft 5 and the workpiece to perform spinning processing.

[0041] When the pressure head 4 is worn out due to long-term use and needs to be replaced, the staff loosens the bolt 85 and presses the wedge block 83 to release the clamping effect with the slot and the limiting effect on the round block 82, so that the staff can remove the pressure head 4 and the round block 82, and connect the round block 82 set on the replaced pressure head 4 with the ring 81, so that the wedge block 83 is clamped with the slot under the elastic force of the spring 84, thereby limiting and pre-fixing the round block 82, and then tightening the bolt 85 to improve the fixing effect of the round block 82 and the pressure head 4.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
