[0002] Punching devices are a common tool when it comes to the use and installation of fasteners. Punching devices are used to create holes in materials so that different parts can be connected through fasteners such as screws, nuts or bolts. Punching devices are usually operated by hand or power. Manual punching devices require the operator to use a handle or lever to apply force to move the tool or drill in the device to create a hole in the material.
[0003] However, when using the punching device for fasteners, the fasteners need to be placed on the base, and then the fasteners on the base are clamped and fixed by a clamp so that the punching drill can normally contact the fasteners and perform drilling processing on the fasteners. Although the fasteners are clamped and fixed by the clamps, because the punching drill contacts the fasteners from top to bottom and performs drilling, although the sides of the fasteners are clamped and fixed by the clamps, it is still easy to cause slight displacement of the fasteners during drilling, which will cause deviations in the drilling positions. Utility Model Content

[0013] The utility model adds a novel auxiliary clamping device to the top right end of the base of the punching device for fasteners. The auxiliary clamping device can reinforce the fasteners that need to be punched on the base. After the fasteners are clamped on the base, the auxiliary clamping device can generate a top-down pressing clamping force on the fasteners, so that the fasteners can be clamped more firmly on the base, ensuring that the punching drill can smoothly punch holes in the fasteners.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] The utility model provides Figure 1-4The punching device for fasteners shown in the figure comprises a base 1 and a lifting pillar 2 vertically arranged on the left side top of the base 1, a lifting bracket 5 is horizontally arranged on the outside of the lifting pillar 2 near the top, a lifting sleeve 6 is vertically arranged on the inside of the lifting bracket 5 near the left end, and the lifting sleeve 6 is sleeved on the outside of the lifting pillar 2, and the lifting sleeve 6 can move up and down on the outside of the lifting pillar 2, a motor frame 7 is arranged on the right end of the lifting bracket 5, a punching motor 8 is arranged on the top of the motor frame 7, a rotor is arranged inside the punching motor 8, an output shaft 10 extending vertically downward is arranged in the rotor, and the lower end of the output shaft 10 is exposed outside the lower end of the motor frame 7, a drill connector 11 is arranged on the lower end of the output shaft 10, a punching drill 12 is clamped inside the bottom end of the drill connector 11, and a punching drill 12 is clamped on the outer wall of the rear end of the motor frame 7 An operating handle 9 is provided. When using the punching device for fasteners, the punching device needs to be placed on the table through the base 1, and then the clamp needs to be installed on the base 1, and the fastener to be punched is placed on the base 1, and the fastener is firmly clamped and fixed on the base 1 through the clamp, and then the punching motor 8 is started, and the operating handle 9 is held and pressed downward, which will drive the motor frame 7 and the lifting bracket 5 to move downward outside the lifting support 2, so that the punching drill bit 12 slowly approaches the fastener. After the punching drill bit 12 contacts the fastener, because the punching motor 8 drives the punching drill bit 12 to rotate at high speed through the drill bit connector 11, the high-speed rotating punching drill bit 12 will perform a hole processing on the fastener, thereby achieving the purpose of completing the punching processing on the fastener.
[0021] like Figure 1 and Figure 2 As shown, a lifting bracket 3 is arranged on the horizontal lower side of the lifting bracket 5, a sleeve hole 4 is arranged inside the lifting bracket 3 near the left end, the sleeve hole 4 is sleeved on the outside of the lifting support 2, and the lifting bracket 3 is fixedly connected to the lifting support 2 by screws, a lifting guide rod 15 is vertically arranged near the top of the right end of the lifting bracket 3, a movable hole 16 is arranged inside the lifting bracket 5 near the right end, the top of the lifting guide rod 15 passes through the movable hole 16, a reset spring 14 is arranged between the lifting bracket 3 and the lifting bracket 5, and the reset spring 14 is sleeved on the lifting guide rod 15 On the outside, an anti-slip stopper 17 is provided on the top of the lifting guide rod 15. During the drilling process, the lifting bracket 5 will move downward, which will slowly compress the reset spring 14. The reset spring 14 will generate a reaction force, thereby lifting the lifting bracket 5 through the lifting bracket 3. After the drilling is completed, the pressed lifting bracket 5 needs to be released. At this time, the compressed reset spring 14 will push the lifting bracket 5 upward, so that the lifting bracket 5 is reset upward, thereby resetting the drilling drill 12 upward, which is convenient for drilling the next fastener.
[0022] like Figure 1 , Figure 3 and Figure 4As shown, an auxiliary clamping device 13 is provided near the top of the right end of the base 1, and the auxiliary clamping device 13 includes a connecting shaft 18, a rotating base plate 19, a clamping bracket 20, a drill hole 21, a clamping plate 22 and a clamping sleeve 23. The right end of the rotating base plate 19 is fixed to the top of the base 1 near the right end through the connecting shaft 18, and a clamping bracket 20 is vertically provided on the top of the left end of the rotating base plate 19. The clamping bracket 20 is sleeved with a clamping sleeve 23 on the outside near the bottom end, and a clamping plate 22 is horizontally provided on the left end of the bottom of the clamping sleeve 23. The drill hole 21 is provided inside the clamping plate 22 near the left end. The rotating base plate 19 can be rotated clockwise or counterclockwise through the connecting shaft 18, and the bottom outer wall of the clamping plate 22 is flush with the bottom outer wall of the clamping sleeve 23, and the clamping sleeve 23 can move up and down outside the clamping bracket 20.
[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the auxiliary clamping device 13 also includes a clamping spring 24, an anti-slip ring 25 and a pulling handle 26.

A clamping spring 24 is arranged between the anti-slip ring 25 and the clamping sleeve 23, and the clamping spring 24 is sleeved on the outside of the clamping bracket 20. After the fastener is clamped on the base 1 by the clamp, in order to increase the clamping effect of the fastener and avoid displacement of the fastener when being punched, it is necessary to use the auxiliary clamping device 13 to reinforce the fastener. Specifically, it is necessary to grasp the pulling handle 26 and pull the clamping sleeve 23 upward so that the clamping sleeve 23 slides upward on the outside of the clamping bracket 20. 24 is also compressed synchronously, and then the supporting sleeve is rotated so that the clamping plate 22 on the clamping sleeve 23 is rotated to the top of the fastener, and it is necessary to ensure that the drill hole 21 inside the clamping plate 22 is vertically below the punching drill 12, and then release the pulling handle 26. At this time, the clamping spring 24 will push the clamping sleeve 23 downward, so that the clamping plate 22 is firmly clamped at the upper end of the fastener, and then the fastener can be punched normally, and the punching drill 12 can smoothly pass through the drill hole 21 and contact the fastener, so that the fastener can be punched normally, and the clamping plate 22 clamped at the top of the fastener can have a reinforcing clamping effect on the fastener, thereby preventing the fastener from being easily displaced when being punched and causing a punching failure.
