Description

Technical Field

[0001] The utility model belongs to the technical field of helmet-shaped parts processing, in particular to a helmet-shaped parts end face drilling device. Background Art

[0002] A helmet is a piece of equipment used to protect the head. It is mostly semicircular and consists of three parts: an outer shell, a lining and a suspension device. The outer shell is made of special steel, fiberglass, reinforced plastic, leather, nylon and other materials to protect the head from damage by bullets, shrapnel and other impact objects.

[0003] During the processing of the helmet, it is necessary to drill holes on its side to fix the lining layer. Due to the special structure of the helmet, when drilling the holes, it is usually necessary to manually hold the helmet while drilling. This operation method is troublesome and labor-intensive, and the quality of the drilling cannot be guaranteed. Utility Model Content

By setting a helmet-shaped part fixing mechanism and adopting a pressure ring type fixing method, the top arc surface of the helmet can be effectively fixed to prevent the helmet-shaped part from being displaced during drilling, thereby improving the drilling quality. By setting a lifting mechanism, the second hydraulic cylinder, the fixing frame and the drilling machine can be driven to move upward or downward, thereby facilitating the adjustment of the drilling position of the helmet-shaped part, reducing the trouble of manual operation, greatly reducing the labor intensity of manual labor, and being easy to use.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The lifting mechanism comprises a screw rod, a servo motor, a lifting block and a limit block, the bottom side of the horizontal end of the fixing frame is rotatably connected to the screw rod, the bottom end of the screw rod is rotatably connected to the upper side of the base, and a handle is installed on the fixing frame. A servo motor is connected to the rod, and a lifting block is screwed on the side of the screw rod. A limit block is fixed on the right side of the lifting block and is slidably connected to the left side of the vertical end of the fixed frame. A second hydraulic cylinder is installed on the left side of the lifting block, and a fixed frame is fixed to the telescopic end of the second hydraulic cylinder. A drilling machine is installed on the left side of the inner cavity of the fixed frame, and the drill bit of the drilling machine extends to the outside of the fixed frame. By setting a helmet-shaped part fixing mechanism and adopting a pressure ring type fixing method, the top arc surface of the helmet can be effectively fixed to prevent the helmet-shaped part from being displaced during drilling, thereby improving the drilling quality. By setting a lifting mechanism, the second hydraulic cylinder, the fixed frame and the drilling machine can be driven to move upward or downward, thereby facilitating the adjustment of the drilling position of the helmet-shaped part, reducing the trouble of manual operation, greatly reducing the labor intensity of manual labor, and being easy to use.

[0007] Furthermore, a rubber pad is provided on the bottom side of the pressing ring. By providing the rubber pad on the bottom side of the pressing ring, it is avoided that the pressing ring causes crushing damage to the helmet-shaped part when fixing the helmet-shaped part, thereby ensuring the processing quality.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: by setting a helmet-shaped part fixing mechanism and adopting a pressure ring type fixing method, the top arc surface of the helmet can be effectively fixed, preventing the helmet-shaped part from being displaced during drilling, and improving the drilling quality; by setting a lifting mechanism, the second hydraulic cylinder, the fixing frame and the drilling machine can be driven to move upward or downward, thereby facilitating the adjustment of the drilling position of the helmet-shaped part, reducing the trouble of manual operation, greatly reducing the labor intensity of manual labor, and being easy to use; by setting a rubber pad on the bottom side of the pressure ring, the pressure ring can be prevented from causing crushing to the helmet-shaped part when fixing it, thereby ensuring the processing quality.
