[0002] A water-saving valve is a device that can distribute flow, reduce pipe diameter, save construction costs, and simplify pipe diameter. It can provide the most suitable stable water flow, efficiently save water, and improve water use comfort. For this reason, it has an increasingly broad application prospect in industrial manufacturing. During the production and manufacturing process of the water-saving valve, it is generally necessary to drill holes in it during the processing process.

[0003] The water-saving valve is mainly composed of a valve body, a valve plate and a valve seat. The valve seat is installed in the valve body, and the valve plate is installed in the valve seat. After the valve body is formed, it is necessary to drill a mounting hole on the valve body. In the prior art, a drilling machine is used for drilling.

[0048] A fixed pad 726 is fixedly installed on the outer surface of the extrusion pad 724, and a corrugated pad 725 is fixedly installed between the opposite surfaces of the fixed pad 726. The corrugated pad 725 is extruded and adapted to the outer wall of the water-saving valve.

[0049] The third embodiment is based on the first and second embodiments. Figure 3 to Figure 4 As shown, the punching assembly 6 includes a rotating shaft 61, which passes through the chassis 2 and is fixedly connected to the output end of the motor 1. A connecting shaft 64 is fixedly installed at the bottom of the rotating shaft 61. A positioning pad 62 is sleeved on the outer surface of the connecting shaft 64. A drill bit 65 is fixedly installed at the axis of the positioning pad 62. A buffer 63 is fixedly installed on the outer surface of the positioning pad 62. The staff starts the motor 1 so that the output end of the motor 1 drives the rotating shaft 61 and the connecting shaft 64 to rotate, so that the positioning pad 62, the buffer 63 and the drill bit 65 rotate to punch holes in the valve body. When the drill bit 65 rotates and drills, the buffer 63 is adapted to the top of the valve body, so as to limit and buffer the outer side of the drill bit 65 to avoid excessive force and deformation at the thinner position of the valve wall.

[0050] The buffer member 63 includes a connecting plate 631, which is distributed in a circumferential shape on the surface of the positioning pad 62. A round rod 632 is fixedly installed at the bottom of the connecting plate 631, and a rotating ball 634 is rotatably installed at the bottom of the round rod 632. When the motor 1 drives the drill bit 65 to rotate, the positioning pad 62 rotates with the drill bit 65.

At this time, the staff places the water-saving valve body on the positioning plate 71, and clamps the valve body through the fitting clamp 72. Then the staff pushes the guide seat 3, so that the guide seat 3 drives the clamping assembly 7 to slide above the guide seat 3 to adjust the position of the fitting clamp 72, so that the valve body is adapted to the punching assembly 6. Then the staff starts the motor 1, so that the output end of the motor 1 drives the punching assembly 6 to rotate to punch holes in the valve body.

[0053] The staff places the valve body on the positioning plate 71 and adjusts the opening and closing angles of the fitting clamp 72 so that the fitting clamp 72 clamps the valve body to open holes in valve bodies of different models.

[0054] The staff places the valve body on the top of the positioning plate 71. When the valve body is placed, it is squeezed with the extrusion pad 724 and the corrugated pad 725, so that the extrusion pad 724 and the corrugated pad 725 are squeezed and deformed, so that the multiple groups of corrugated pads 725 on the outside of the valve body fit with the surface of the valve body, thereby clamping and fixing the outside of the valve body and avoiding collision between the valve body and the clamping device when the valve body vibrates during drilling, which affects the accuracy of the valve body drilling.

[0055] When drilling a hole in the valve body, the worker pushes the mounting plate 31 so that the mounting plate 31 drives the external block 32 to slide on the surface of the slide rod 35, thereby adjusting the position of the valve body in the clamping assembly 7 to facilitate adjustment of the drilling position.

[0056] The staff starts the motor 1 so that the output end of the motor 1 drives the rotating shaft 61 and the connecting shaft 64 to rotate, so that the positioning pad 62, the buffer 63 and the drill bit 65 rotate to drill a hole in the valve body. When the drill bit 65 rotates and drills, the buffer 63 is matched with the top of the valve body, thereby limiting and buffering the outside of the drill bit 65 to avoid excessive force and deformation at the thinner position of the valve wall.

[0057] When the motor 1 drives the drill bit 65 to rotate, the positioning pad 62 rotates with the drill bit 65. When the drill bit 65 rotates and drills, the fitting pad 635 fits against the top of the valve body and makes the fitting pad 635 rotate on the surface of the rotating ball 634. At this time, multiple groups of fitting pads 635 are balanced and supported on the surface of the position where a hole needs to be opened, and when the drill bit 65 moves downward, the fitting pad 635 and the valve body are squeezed and deformed to buffer the vibration frequency generated during drilling, thereby preventing the valve body from shaking due to vibration during drilling.
