Currently, most of these tightening methods are done manually with tools, which results in low overall processing efficiency and poor consistency. Some methods use tightening machines, but because there are many types of pump covers, each model requires a separate tightening machine, leading to poor overall compatibility of each machine.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] Example 1:

[0024] An overflow valve assembly tightening machine includes a worktable 1, a controller, a clamp 6, and a tightening mechanism, wherein:

[0025] The clamp 6 includes a bracket, a fixing plate 7, a clamping seat 10, a clamping arm 11, a corner cylinder 12, and a positioning pin 8, wherein:

[0026] The bracket is fixed on the workbench 1;

[0027] The fixing plate 7 is fixed on the bracket and has multiple pin holes 9 for the positioning pins 8 to be inserted and locked.

[0028] The clamping seat 10 is fixed on the fixing plate 7, and a mounting position matching the position of the overflow valve assembly mounting hole 3 of the pump cover 2 is provided on the mounting position, and a V-shaped groove 13 is provided on one side of the mounting position.

[0029] An angle cylinder 12 is fixed on the fixed plate 7 and is used to drive the clamping arm 11 to rotate and press down.

[0030] The clamping arm 11 is fixed on the actuating part of the rotary cylinder 12. It also has a mounting position that matches the position of the overflow valve assembly mounting hole 3 of the pump cover 2. It is used to match the mounting position of the clamping seat 10 to clamp the position of the overflow valve assembly mounting hole 3 on the pump cover 2. A V-shaped protrusion is provided on one side of the mounting position, which matches the V-shaped groove 13 of the clamping seat 10. This makes it less likely to loosen after clamping.

[0031] When the clamp 6 works, select the appropriate pin hole 9 according to the pump cover 2, insert the positioning pin 8 into the corresponding pin hole 9, then insert the pump cover 2 into the positioning pin 8 for positioning, and then start the corner cylinder 12 to clamp the pump cover 2 through the clamping seat 10 and the clamping arm 11.

[0032] The tightening mechanism includes a moving component 15 and a tightening component.

[0033] The moving component 15 mainly includes a guide rail, a slider, and a cylinder for moving the slider vertically, the purpose of which is to move the tightening component vertically.

[0034] The tightening assembly includes a motor 16, a reducer 17, a dynamic torque sensor 18, a sleeve 19, and a displacement sensor 22. The motor 16 is fixed on the slider, the reducer 17 is connected to the output shaft of the motor 16, the dynamic torque sensor 18 is connected to the output end of the reducer 17, and the sleeve 19 is connected to the output end of the dynamic torque sensor 18. In this way, the motor 16 can drive the sleeve 19 to rotate, and the dynamic torque sensor 18 can detect the real-time torque. In this embodiment, the dynamic torque sensor 18 is a static constant torque sensor. The displacement sensor 22 is fixed on the slider and its main purpose is to detect the overall tightening depth of the tightening assembly. In this embodiment, a KTR linear displacement sensor 22 is used. The motor 16, the dynamic torque sensor 18, and the displacement sensor 22 are all electrically connected to the controller.

[0035] Example 2:

[0036] The difference from Embodiment 1 is that in Embodiment 2, the sleeve 19 is also provided with a guide rod 20 and a spring 21. The sleeve 19 is provided with a mounting hole, and the guide rod 20 is provided with a waist-shaped hole. The guide rod 20 is vertically slidably connected to the inside of the sleeve 19 by a pin passing through the mounting hole and the waist-shaped hole. In the initial state, the guide rod 20 is squeezed out of the sleeve 19 by the spring 21, and the front end of the guide rod 20 is matched with the overflow valve assembly 5. When the user puts the overflow valve assembly 5 into the pump cover 2, the moving component 15 controls the tightening component to move down. At this time, the guide rod 20 will first extend into the overflow valve assembly 5 and straighten the overflow valve assembly 5. After that, when the moving component 15 drives the tightening component to move down to the position, the guide rod 20 will be squeezed into the inside of the sleeve 19. At this time, the overflow valve assembly 5 will be circumferentially limited in the sleeve 19. Then, the motor 16 is controlled to work to drive the sleeve 19 to rotate, and the overflow valve assembly 5 is tightened onto the pump cover 2.
