[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The utility model aims to provide a pneumatic valve rubber diaphragm punching tool to solve the problems existing in the above-mentioned prior art, with a simple structure and easy operation.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] The utility model provides a pneumatic valve rubber diaphragm punching tool, such as Figures 1-2As shown, it includes: a base 10, a fixing frame 20 and a punch 30. The base 10 is used to place the pneumatic valve rubber diaphragm on the base 10; one end of the fixing frame 20 is used to be fixedly connected to the base 10; the punch 30 is used to be slidably connected to the fixing frame 20, and can be aligned with the position where the pneumatic valve rubber diaphragm placed on the base 10 needs to be punched to punch the pneumatic valve rubber diaphragm. By setting the base 10, the pneumatic valve rubber diaphragm that needs to be punched is placed on the base 10, the bottom end of the punch 30 is moved to align with the position of the pneumatic valve rubber diaphragm, and the punch 30 is pushed to slide on the fixing frame 20, so that the bottom end of the punch 30 punches the pneumatic valve rubber diaphragm. The structure is simple and the operation is convenient.

[0022] In a preferred embodiment, the base 10 is a circular base 10 with a bottom hole 11 at the center thereof for locating the position where the rubber diaphragm of the pneumatic valve needs to be punched. The base 10 is made of iron to ensure the stability and durability of the tool.

[0023] In a preferred embodiment, the fixing frame 20 is an inverted L-shaped structure, and the fixing frame 20 includes a first fixing plate and a second fixing plate. The bottom of the first fixing plate is used to be fixedly connected to the side wall of the base 10, and one end of the second fixing plate is used to be fixedly connected to the top of the first fixing plate. A through hole 21 is provided at the end of the second fixing plate away from the first fixing plate. The through hole 21 is used for the punch 30 to pass through, and the axis of the through hole 21 is collinear with the axis of the bottom hole 11. The inverted L-shaped structure of the fixing frame 20 makes the movement trajectory of the punch 30 more stable; it ensures the movement trajectory of the punch 30 and effectively improves the accuracy of punching.

[0024] In a preferred embodiment, the bottom end of the punch 30 is rounded.
