[0031] In order to be able to describe the present utility model in detail, the following specifically describes the handheld gun - type pneumatic drill punching tooling of the present utility model:

[0032] Please refer to Figure 1 As shown, the present utility model provides a handheld gun - type pneumatic drill punching tooling, including: a base 1, a guiding assembly, and a clamping assembly 5. Among them, the guiding assembly includes a guide post 2, a guide sleeve 3, and an elastic member 4. The guide post 2 is vertically arranged on the base 1. The guide sleeve 3 is sleeved on the guide post 2. The elastic member 4 is sleeved on the guide post 2 and is located between the bottom end of the guide sleeve 3 and the base 1. The clamping assembly 5 has a clamping position for installing a handheld gun - type pneumatic drill. The clamping assembly 5 is arranged at the top end of the guide sleeve 3 and can reciprocate along the axial direction of the guide post 2 together with the guide sleeve 3.

[0033] Specifically, the base 1 is used to carry the guiding component and the clamping component 5, and is placed on the surface of the component to be drilled before the handheld gun-shaped pneumatic drill performs drilling; the guide post 2 is perpendicular to the base 1 and can be specifically arranged on the base 1 by welding to ensure that the drilling is carried out along the direction of the guide post 2, that is, perpendicular to the component to be drilled; the clamping component 5 is connected to the guide sleeve 3, which facilitates the clamping component 5 to move axially along the guide post 2 together with the guide sleeve 3 to compress the elastic member 4 or reset under the action of the elastic member 4; the clamping component 5 can be welded to the guide sleeve 3 and is used to clamp the handheld gun-shaped pneumatic drill.

[0034] During use, before drilling, the handheld gun-shaped pneumatic drill is installed on the clamping position of the clamping component 5 and fastened, and the base 1 is placed on the surface of the component to be drilled. When drilling, the guide sleeve 3 is pressed by the handheld gun-shaped pneumatic drill, and then the elastic member 4 is pressed to perform drilling. After the drilling is completed, under the elastic force of the elastic member 4, the handheld gun-shaped pneumatic drill can automatically lift and reset, leaving the drilling surface of the component, and the drilling operation is completed. By using this tooling, the perpendicularity of the drilling of the handheld gun-shaped pneumatic drill is ensured, the hole position accuracy during the drilling of thick plate materials is ensured, the defect of poor drilling perpendicularity caused by artificial skill differences is eliminated, and the flexibility of the drilling of the handheld gun-shaped pneumatic drill is improved.

[0035] In some embodiments, the base 1 is an integral flat plate structure, at least including a main body portion 11, and a relief notch 12 is formed on the main body portion 11, and the relief notch 12 corresponds to the clamping position. Specifically, the flat plate structure of the base 1 is conducive to ensuring that it can be stably placed on the surface of the component to be drilled and ensuring the stability of the drilling process. The relief notch 12 is used for the handheld gun-shaped pneumatic drill to make a relief when drilling, which is conducive to its ability to drill the component from the relief notch 12.

[0036] Exemplarily, the relief notch 12 has a rectangular structure. In this embodiment, the relief notch 12 has a rectangular structure, which is convenient for processing, and the rectangular relief notch 12 can have a rounded chamfer; in other embodiments, the relief notch 12 can have other shapes, such as circular, oval, etc., as long as it is convenient for the handheld gun-shaped pneumatic drill to drill from the relief notch 12, and the specific is not limited.

[0037] In the above embodiment, a flanging portion 13 is provided upward on a pair of opposite sides of the main body portion 11, and the flanging portion 13 is in arc transition with the main body portion 11. Among them, the setting of the flanging portion 13 is conducive to improving the stability of the base 1, and at the same time, ensuring the smoothness of its edge, which is conducive to the operator to take it.

[0038] In some embodiments, the handheld gun-shaped pneumatic drill punching tooling further includes a fixing member 6, which is disposed on the base 1, and the bottom end of the guide post 2 passes through the fixing member 6. Specifically, in this embodiment, the fixing member 6 is welded to the base 1. The fixing member 6 can be a nut, and the bottom end of the guide post 2 passes through the nut. The setting of the fixing member 6 can better limit the elastic member 4.

[0039] In the above embodiment, the bottom end of the guide sleeve 3 has a limiting portion 31 protruding from the circumferential side wall of the guide sleeve 3, and the two ends of the elastic member 4 are respectively connected to the limiting portion 31 and the fixing member 6. Specifically, the limiting portion 31 is used for axially limiting the top end of the elastic member 4, and the fixing member 6 is used for axially limiting the bottom end of the elastic member 4. In this way, it can be ensured that both ends of the elastic member 4 are reliably limited. The limiting portion 31 can be an annular structure protruding from the circumferential side wall of the guide sleeve 3, or the limiting portion 31 can be at least two protruding structures symmetrically arranged along the circumferential direction of the guide sleeve 3, and the outer peripheral dimension of the limiting portion 31 needs to be at least larger than the outer peripheral dimension of the elastic member 4, and the outer peripheral dimension of the fixing member 6 also needs to be at least larger than the outer peripheral dimension of the elastic member 4. And, the two ends of the elastic member 4 are respectively welded to the limiting portion 31 and the fixing member 6, and the fixing member 6 is welded to the base 1, thereby preventing the circumferential rotation of the guide sleeve 3, and further preventing the clamping assembly 5 from rotating around the guide post 2 in the horizontal plane.

[0040] It should be noted that the handheld gun-shaped pneumatic drill punching tooling further includes a limiting member 7 and a fastening member 8. The top end of the guide post 2 is radially provided with the fastening member 8, and the limiting member 7 is locked between the clamping assembly 5 and the fastening member 8. Among them, by using the cooperation of the limiting member 7 and the fastening member 8, the clamping assembly 5 can be axially limited to prevent the clamping assembly 5 from disengaging from the guide post 2 when moving axially along the guide post 2.

[0041] In some embodiments, the clamping assembly 5 includes a clamp 51 and a connecting member 52 connected to the clamp 51. The clamp 51 is connected to the guide sleeve 3 through the connecting member 52. The clamp 51 includes a clamping ring 511 forming the clamping position and a locking member 512 for locking the clamping ring 511. Specifically, the two ends of the connecting member 52 are respectively connected to the clamp 51 and the guide sleeve 3. The clamping ring 511 of the clamp 51 is used to form a clamping position for installing the handheld gun-shaped pneumatic drill. By tightening the locking member 512, the handheld gun-shaped pneumatic drill can be clamped. When punching, operate the handheld gun-shaped pneumatic drill to press down, drive the guide sleeve 3 to press down through the clamping assembly 5, and then compress the elastic member 4. The handheld gun-shaped pneumatic drill approaches the punching surface of the component for punching; after punching, under the elastic force of the elastic member 4, the handheld gun-shaped pneumatic drill automatically lifts and resets, leaving the punching surface of the component to complete the punching.

[0042] It can be understood that the first end of the connecting member 52 is adapted to the circumferential arc surface of the clamp 51, and the second end of the connecting member 52 is provided with a mounting hole adapted to the guide post 2 so that the guide post 2 extends out of the mounting hole. Among them, the adaptation of the first end of the connecting member 52 to the circumferential arc surface of the clamp 51 enables better welding with the clamp 51; the provision of the mounting hole at the second end of the connecting member 52 facilitates sleeving on the guide post 2 and welding with the top end of the guide sleeve 3; and, a flat surface portion 21 is provided on the side wall of the guide post 2, and the shape of the mounting hole of the connecting member 52 is adapted to the flat surface portion 21, thereby ensuring the positioning and installation between the connecting member 52 and the guide post 2.

[0043] In summary, the hand-held gun-shaped pneumatic drill punching tooling provided by the present utility model can conveniently clamp the hand-held gun-shaped pneumatic drill onto the clamping position of the clamping assembly 5, which is conducive to the hand-held gun-shaped pneumatic drill pressing the elastic member 4 through the guide sleeve 3 during punching, ensuring the perpendicularity of the punching of the hand-held gun-shaped pneumatic drill, ensuring the hole position accuracy during punching of thick sheet materials, eliminating the defect of poor punching perpendicularity caused by differences in manual skills, and improving the flexibility of punching with the hand-held gun-shaped pneumatic drill.

[0044] The above embodiments merely illustrate the principles and effects of the present utility model, rather than limiting the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
