DETAILED DESCRIPTION

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a punching device that can avoid the deviation of a large gear, including a workbench 1, a puncher 2 is fixed on the top of the workbench 1, a support block 3 is fixed on the top of the workbench 1, a positioning mechanism 4 for fixing the large gear is arranged on the support block 3, and an adjustment mechanism 5 is arranged on the positioning mechanism 4.

[0024] Specifically, the positioning mechanism 4 includes a rotating column 41, a threaded rod 42, a knob 43, a threaded sleeve 44, a hinged rod 46, a moving rod 45, an extrusion block 48 and a magnetic block 49; the supporting block 3 is penetrated by the rotating column 41, and the rotating column 41 is rotatably connected to the penetration point of the supporting block 3, the right side of the rotating column 41 is rotatably installed with a threaded rod 42, the right end of the threaded rod 42 is fixed with a knob 43, the rotating column 41 is penetrated by the moving rod 45, and the moving rod 45 is slidably connected to the penetration point of the rotating column 41, the outer wall of the threaded rod 42 is threadedly connected with a threaded sleeve 44, the threaded sleeve 44 is hinged with a hinged rod 46, the end of the hinged rod 46 away from the threaded sleeve 44 is hinged on the moving rod 45, the end of the moving rod 45 away from the hinged rod 46 is fixed with an extrusion block 48, the material of the extrusion block 48 is rubber material, and the extrusion block 48 is provided with four groups, and the four groups of extrusion blocks 48 are arranged in a circular array with the center point of the threaded rod 42. When it is necessary to punch a hole on the large gear, the large gear can be put on the extrusion block 48. The outer wall of the extrusion block 48 is fixed with a magnetic block 49, and the side wall of the large gear is adsorbed on the magnetic block 49 to keep the large gear in a vertical state. By turning the positive button 43, the threaded sleeve 44 can be moved close to the support block 3, so that the threaded sleeve 44 squeezes the hinged rod 46, and the hinged rod 46 squeezes the moving rod 45 to move at the penetration point. The inner wall of the large gear can be squeezed by the extrusion block 48, and the large gear can be quickly positioned. By starting the punching machine 2, the large gear can be punched, and the large gear can be positioned by the extrusion block 48 to prevent the large gear from shifting during punching.

[0025] Specifically, the adjustment mechanism 5 includes a groove 51, a slider 52, a return spring 54, a pull rod 53, a limit rod 55 and a limit hole 56. The groove 51 is provided on the outer wall of the rotating column 41, and the slider 52 is slidably installed on the inner wall of the groove 51. There are two groups of sliders 52, and the two groups of sliders 52 are symmetrically arranged with the center line of the rotating column 41 in the vertical direction as the symmetry axis. A return spring 54 is fixed on one side of the slider 52, and a pull rod 53 is fixed on the other side of the slider 52. The side of the return spring 54 away from the slider 52 is fixed to the inner wall of the groove 51. By setting the return spring 54, the slider 52 can be reset. The limit rod 55 is fixed on the side of the slider 52 away from the pull rod 53. The side wall of the support block 3 is provided with multiple groups of limit holes 56 in a circular array. The outer wall of the limit rod 55 and the limit holes 5 6 fits the inner wall of the large gear 6, and the limiting rod 55 and the limiting hole 56 are set to limit the rotating column 41. Then, after the large gear is clamped, when it is necessary to punch holes in different positions of the large gear, the pull rod 53 can be pulled away from the support block 3, so that the slider 52 drives the limiting rod 55 to move out of the limiting hole 56, and then the limiting of the rotating column 41 can be released, and the pull rod 53 can be directly rotated to drive the rotating column 41 to rotate, drive the positioning mechanism 4 to rotate, and make the large gear rotate. When it rotates to the position where drilling is required, the pull rod 53 can be released. Because the reset spring 54 is in a stretched state, the limiting rod 55 can be extended into the limiting hole 56, and then the rotating column 41 can be fixed, which is convenient for the staff to adjust the direction of the large gear and facilitate multi-directional drilling operations.

[0026] Working principle: when it is necessary to perform drilling operations on the large gear, the large gear can be put on the extrusion block 48 so that the side wall of the large gear fits with the magnetic block 49, so that the large gear can be in a vertical state, and by turning the knob 43 forward, the threaded sleeve 44 can be moved closer to the support block 3, so that the threaded sleeve 44 squeezes the hinged rod 46, and the hinged rod 46 squeezes the moving rod 45 to move in the penetration part, and the inner wall of the large gear can be squeezed by the extrusion block 48 to quickly position the large gear, and by starting the punching machine 2, the large gear can be punched, and the large gear can be positioned by the extrusion block 48 to prevent the large gear from shifting during drilling.

[0027] When it is necessary to punch holes in different positions of the large gear, the pull rod 53 can be pulled away from the support block 3, so that the slider 52 drives the limiting rod 55 to move out of the limiting hole 56, thereby releasing the limit on the rotating column 41, and the pull rod 53 can be directly rotated to drive the rotating column 41 to rotate, drive the positioning mechanism 4 to rotate, and make the large gear rotate. When it rotates to the position where a hole needs to be punched, the pull rod 53 can be released. Because the reset spring 54 is in a stretched state, the limiting rod 55 can be extended into the limiting hole 56, thereby fixing the rotating column 41, making it convenient for the staff to adjust the direction of the large gear and facilitate multi-directional punching operations. When the drilling is completed, the knob 43 can be reversed to make the threaded sleeve 44 away from the support block 3. Through the hinged rod 46, the moving rod 45 can be pulled close to the threaded rod 42, thereby making the four groups of extrusion blocks 48 close to each other, thereby making the extrusion blocks 48 release the extrusion and pressure on the inner wall of the large gear, thereby releasing the positioning of the large gear.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
