They are mainly used in the manufacturing of hydraulic pump housings in the automotive and construction machinery industries, and need to meet the requirements of high precision and high efficiency assembly.

[0003] The press-fit fixture for water pump housing requires workers to accurately place the workpiece under the pressure plate and hold it in place. This requires a high level of skill and concentration from the workers, resulting in slow work efficiency. Furthermore, traditional fixtures are not suitable for different types of workpieces, requiring workers to replace the entire fixture, which is time-consuming and labor-intensive.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figures 1-3 The water pump housing pressing fixture shown includes a frame 1, a square box 6, and a horizontal drive mechanism. The pressing mechanism is located on the top of the frame 1 and is used to press the water pump housing. The square box 6 is slidably connected to the top of the frame 1. A sliding rod 11 is slidably connected to the inner wall of the square box 6. A stop plate 12 is fixedly connected to the end of the sliding rod 11 away from the square box 6. The horizontal drive mechanism is located outside the frame 1 and is used to drive the square box 6 to move. The outer wall of the square box 6 is provided with multiple sliding rods 11, which are horizontally spaced. In specific use: the pressing mechanism is used to press the water pump housing. Before pressing, the worker roughly places the water pump housing on the surface of the frame 1. While the pressing mechanism is working, the horizontal drive mechanism drives the square box 6 to move. The square box 6 drives the stop plate 12 to move through the sliding rods 11. The stop plate 12 pushes the water pump housing to the center position, improving the worker's loading speed. At the same time, the use of multiple independently sliding sliding rods 11 makes the stop plate 12 suitable for different models of water pump housings, reducing line change time and inventory costs of special fixtures.

[0029] One aspect is that the pressing mechanism includes a fixed frame 2 and a driving component 4. The fixed frame 2 is fixedly connected to the top of the frame 1, and the driving component 4 is fixedly connected to the top of the fixed frame 2. The output end of the driving component 4 is fixedly connected to a pressure plate 3. The driving component 4 uses a hydraulic cylinder that is already available on the market. The frame 1 is equipped with control buttons. The control buttons are used to control the hydraulic cylinder to drive the pressure plate 3 to move, and the pressure plate 3 is used to achieve the purpose of pressing the workpiece.

[0030] On the other hand, the horizontal drive mechanism includes a lifting plate 5 and a second trapezoidal block 10. The lifting plate 5 is slidably connected to the outer wall of the fixed frame 2. The outer wall of the fixed frame 2 has a groove, and the lifting plate 5 is slidably disposed inside the groove, so that the lifting plate 5 can move vertically along the groove. The lifting plate 5 is fixedly connected to the top of the fixed frame 2. The outer wall of the lifting plate 5 is fixedly connected to a first trapezoidal block 8. The second trapezoidal block 10 is slidably connected to the top of the frame 1. A support rod 16 is fixedly connected between the second trapezoidal block 10 and the square box 6. An elastic component is provided on the outside of the sliding rod 11. The elastic component includes a circular rod 14 and a second spring 15. The circular rod 14 is fixedly connected to the inner wall of the square box 6. The sliding rod 11 is slidably sleeved on the outer wall of the circular rod 14. The second spring 15 is fixedly connected between the sliding rod 11 and the square box 6. The first trapezoidal block 8 is moved by the synchronous movement of the lifting plate 5 and the pressure plate 3. The outer walls of the first trapezoidal block 8 and the second trapezoidal block 10 are both provided with parallel inclined surfaces. The first trapezoidal block 8 and the second trapezoidal block 10 push against each other. The second trapezoidal block 10 moves, using the square box 6 to drive the sliding rod 11 and the abutment plate 12 to move synchronously. Multiple abutment plates 12 abut against the water pump housing, pushing the water pump housing to the center of the frame 1 surface. The abutment plates 12 compress the second spring 15, allowing the multiple sliding rods 11 to move independently. In practical use: when pressing the water pump housing, the worker places the water pump housing on top of the frame 1, activates the drive unit 4, which drives the pressure plate 3 and the lifting plate 5 to move synchronously. The lifting plate 5 then drives the first trapezoidal block 10... The first trapezoidal block 8 moves until it abuts against the second trapezoidal block 10. The first trapezoidal block 8 pushes the second trapezoidal block 10 to move horizontally. The second trapezoidal block 10 drives the square box 6 to move through the support rod 16. The square box 6 drives the abutment plate 12 to move through the sliding rod 11 until the abutment plate 12 abuts against the outer wall of the water pump housing. The abutment plate 12 pushes the water pump housing to the center while squeezing the second spring 15. Multiple abutment plates 12 achieve the purpose of pushing the water pump housing to the center position and are applicable to different models of water pump housing.

[0031] Preferably, the outer wall of the square box 6 is provided with a reset mechanism, which includes a fixed plate 13 and a first spring 7. The fixed plate 13 is fixedly connected to the top of the frame 1, and the first spring 7 is fixedly connected between the square box 6 and the fixed plate 13. During the movement of the square box 6, the first spring 7 is stretched. When the lifting plate 5 drives the first trapezoidal block 8 to move upward until the first trapezoidal block 8 and the second trapezoidal block 10 no longer collide, the first spring 7 resets and drives the square box 6 to move in the opposite direction, automatically releasing the fixed clamping of the water pump housing.

[0032] In addition, there are two square boxes 6 arranged horizontally and symmetrically. The anti-slip pad 17 is fixedly connected to the side of the abutment plate 12 away from the sliding rod 11. The inner wall of the first trapezoidal block 8 is rotatably connected to the roller 9. There are multiple rollers 9 arranged at intervals. The rollers 9 abut against the outer wall of the second trapezoidal block 10, so that the first trapezoidal block 8 can drive the second trapezoidal block 10 to move horizontally more smoothly. The anti-slip pad 17 is used to increase the clamping force of the abutment plate 12 on the water pump housing.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
