[0020] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] Example: Figure 1-4 As shown, an automatic assembly mechanism for a water pump housing buffer pad includes a frame 9, on which a water pump fixture 12 is mounted. The water pump fixture 12 includes a water pump mounting base 14, on which a water pump 15 is mounted. A rotary pressing cylinder 16 is mounted on the side of the water pump 15. A buffer pad clamping assembly component 5 is mounted on the upper end of the water pump fixture 12. The buffer pad clamping assembly component 5 includes a slide plate 21. A buffer pad locking head 23 is mounted on the lower end face of the slide plate 21. A laser displacement sensor 24 is mounted on the front end of the buffer pad locking head 23. A vacuum tube connector 22 is mounted on the side end of the buffer pad locking head 23. A servo motor 20 is mounted on the upper end face of the slide plate 21. A torque sensor 25 is mounted between the servo motor 20 and the buffer pad locking head 23. A displacement seat 3 is provided between the slide plate 21 and the frame 9. A Z-axis lifting module 4 is provided between the displacement seat 3 and the slide plate 21. A Y-axis transverse module 6 and a Y-axis transverse guide rail 7 are provided between the Z-axis lifting module 4 and the displacement seat 3. An X-axis transverse module 2 and an X-axis transverse guide rail 8 are provided between the two ends of the displacement seat 3 and the frame 9, respectively.

[0022] An automatic oiling fixture 10 is provided at the front end of the water pump fixture 12. The automatic oiling fixture 10 includes an oiling fixture base 19, on which three buffer pad fixtures 17 are provided. A product material placement platform 1 is provided on the side of the frame 9. A pressure tank 13 connected to the buffer pad fixtures 17 is provided inside the product material placement platform 1. A return pipe 18 connected to the buffer pad fixtures 17 is provided at the lower part of the oiling fixture base 19. A residual liquid return tank 11 connected to the return pipe 18 is provided inside the frame 9.

[0023] The robot or operator places the water pump housing on the water pump fixture 12, then takes the buffer pad and places it on the buffer pad fixture 17 (the order of placing the housing and the buffer pad is not strictly required). The operator then leaves the equipment's operating area, presses the double start button near the frame 9, rotates the pressing cylinder 16 to press down the product, and the equipment begins to operate.

[0024] The pressure tank 13 supplies lubricating fluid, which is delivered to the automatic oiling fixture 10 via an air pipe controlled by a solenoid valve to achieve self-lubrication of the buffer pad. The residual fluid is recovered into the residual fluid return tank 11 through the bottom return pipe 18.

[0025] The displacement seat 3 moves the punching pad clamping assembly 5 horizontally above the buffer pad. The laser displacement sensor 24 detects the height of the buffer pad and determines whether there are defective products (defective buffer pads require equipment feedback signals and manual intervention). Then, it moves down to grab the buffer pad. During the grabbing process, the buffer pad locking head 23 first contacts the buffer pad to achieve complete surface adhesion. Then, it connects the vacuum tube through the vacuum tube connector 22 to achieve the buffer pad suction action. The vacuum breaking signal from the integrated vacuum generator indicates whether the product grabbing is complete. The buffer pad is then grabbed to the pre-locking height, transported to the pre-locking position by the displacement seat 3, and then lowered to the locking position. The locking action is driven by the servo motor 20, which drives the central rotating shaft to complete the locking action. The locking result is determined by the torque value output by the torque sensor 25 to determine whether the buffer pad is properly locked. The grabbing and locking action is repeated until the third buffer pad is locked. After the buffer pad locking process of a single water pump product is completed, the equipment is reset as a whole, and then the finished product is taken away by a robot or manually and transported to the next work station (NG products are recycled to NG storage boxes).

[0026] In summary, this automatic assembly mechanism for water pump housing buffer pads features a simple structure, good operational stability, and high efficiency. It simplifies the processing workflow and automates the assembly of water pump housing buffer pads. By changing the tooling, it can accommodate the assembly of buffer pads of various specifications from multiple products.
