Description

Technical Field

[0001] This utility model relates to the technical field of water pump assembly, and in particular to a water pump O-ring assembly fixture. Background Technology

[0002] In the thermal management integrated module, pump assembly refers to assembling the large / small O-rings onto the pump and then placing the pump into the oiling test equipment.

[0003] Existing O-ring assembly fixtures for water pumps, such as the O-ring assembly fixture disclosed in utility model patent application number 202322881581.1, mainly include a housing, a rotating mechanism, a slider assembly, and a telescopic mechanism. A groove is provided along the radial direction of the housing, and the slider assembly is connected to the groove. A protrusion is provided on the slider assembly. In use, the protrusion engages with the O-ring, and the slider assembly can reciprocate relative to the groove under the drive of the rotating mechanism to cause the O-ring to expand or contract. After the O-ring has expanded, a workpiece is inserted into the center of the expanded O-ring.

[0004] However, since the water pump does not have an O-ring limiting groove, the O-ring is subjected to uneven force during assembly, which can cause the O-ring to rebound after being installed in place. When the equipment detects whether the O-ring is installed in place, it is easy to trigger an alarm, which increases the cycle time of this station and causes product accumulation. Moreover, if the equipment misjudges and judges the unqualified as qualified, the O-ring is prone to getting stuck when the servo press presses the water pump into the integrated module, which increases the risk of leakage of the integrated module. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a water pump O-ring assembly fixture that not only ensures uniform force distribution during the assembly process and prevents rebound after assembly, but also improves the pass rate of equipment "installation in place" inspection and reduces the risk of leakage of integrated modules.

[0006] This utility model discloses a water pump O-ring assembly fixture, including a fixing mechanism, a limiting mechanism, and an installation mechanism. The limiting mechanism is installed on the fixing mechanism and limits the installation mechanism. The installation mechanism is installed on the limiting mechanism and installs the O-rings on the water pump. The operator pre-installs the large and small O-rings onto the installation mechanism, aligns the water pump assembly surface downwards with the installation mechanism, presses down on the water pump, and the water pump presses against the installation mechanism. Under the limiting action of the limiting mechanism, the installation mechanism installs the large and small O-rings onto the water pump.

[0007] Preferably, the fixing mechanism includes a base plate, a base, four sets of first bolts and four sets of second bolts. The base plate is placed on the workbench, the bottom end of the base is connected to the top end of the base plate, and four sets of limiting grooves are opened on the base. The four sets of first bolts are connected and installed between the base plate and the base, and the four sets of second bolts are connected and installed between the base plate and the workbench. The operator uses the four sets of first bolts to fix the base plate and the base, and then uses the four sets of second bolts to fix the base plate to the workbench.

[0008] Preferably, the limiting mechanism includes four sets of first springs, a limiting block, four sets of third bolts, and a limiting pin. The four sets of first springs are placed in four sets of limiting grooves in the base. The bottom end of the limiting block is connected to the top end of the base. The four sets of third bolts are connected and installed between the base and the limiting block. The limiting pin is installed on the limiting block. The operator installs the installation mechanism into the limiting block, and then fixes the limiting block to the base using the four sets of third bolts. The four sets of first springs hold the installation mechanism in place, and the limiting pin is inserted into the first spring to limit the installation mechanism.

[0009] Preferably, the installation mechanism includes a movable block, a first push rod, four sets of fourth bolts, a second spring, and a second push rod. The movable block is fixedly connected to the first push rod by the four sets of fourth bolts. The second spring is installed inside the first push rod, and the top end of the second spring is connected to the bottom end of the second push rod. The operator places the second push rod and the second spring into the first push rod in sequence, and then uses the four sets of fourth bolts to fix the movable block to the bottom end of the first push rod, placing the entire installation mechanism inside the limiting block.

[0010] Compared with the prior art, the advantages of this utility model are as follows: the workers pre-install the large O-ring and the small O-ring onto the installation mechanism, align the water pump assembly surface downwards with the installation mechanism, press down on the water pump, and the water pump presses against the installation mechanism. Under the limiting action of the limiting mechanism, the installation mechanism installs the large and small O-rings onto the water pump. Attached Figure Description

Detailed Implementation

[0014] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0015] Example 1

[0016] This utility model discloses a water pump O-ring assembly fixture, including a fixing mechanism 01; it also includes a limiting mechanism 02 and an installation mechanism 03. The limiting mechanism 02 is installed on the fixing mechanism 01 and limits the installation mechanism 03. The installation mechanism 03 is installed on the limiting mechanism 02 and installs the O-ring on the water pump. The fixing mechanism 01 includes a base plate 11, a base 12, four sets of first bolts 13 and four sets of second bolts 14. The base plate 11 is placed on the operating table. The bottom end of the base 12 is connected to the top end of the base plate 11. The base 12 has four sets of limiting grooves. The four sets of first bolts 13 are connected and installed between the base plate 11 and the base 12. The four sets of second bolts 14 are connected and installed between the base plate 11 and the operating table. The limiting mechanism 02 includes four sets of first springs 21, limiting blocks 22, four sets of third bolts 23 and limiting pins 24. 4. Four sets of first springs 21 are placed in four sets of limiting grooves in the base 12. The bottom end of the limiting block 22 is connected to the top end of the base 12. Four sets of third bolts 23 are connected and installed between the base 12 and the limiting block 22. The limiting pin 24 is installed on the limiting block 22. When it is working, firstly, the large and small O-rings are installed on the installation mechanism 03. The operator takes the water pump and aligns the water pump with the assembly surface facing down and presses it down. After the water pump contacts the installation mechanism 03, the installation mechanism 03 begins to move downward. The installation mechanism 03 compresses the four sets of first springs 21 and contracts, so that the large and small O-rings are squeezed into place. The large and small O-rings are squeezed into place by the horizontal plane, so the force is uniform. After the O-rings are squeezed into place, they are not easy to rebound, thereby improving the pass rate of "installation in place test" and reducing the risk of ring clamping during pressing.

[0017] Example 2

[0018] like Figures 1 to 2As shown, this utility model discloses a water pump O-ring assembly fixture based on embodiment 1. The mounting mechanism 03 includes a movable block 31, a first push rod 32, four sets of fourth bolts 33, a second spring 34, and a second push rod 35. The movable block 31 is fixedly connected to the first push rod 32 by the four sets of fourth bolts 33. The second spring 34 is installed inside the first push rod 32, and the second push rod 35 is installed inside the first push rod 32 with the top end of the second spring 34 connected to the bottom end of the second push rod 35. During operation, firstly, the small O-ring is pre-installed on the second push rod 35, and the large O-ring is installed on the first push rod 32. After the water pump is taken out, the water pump mounting surface is facing down and aligned with the second push rod 35. After the water pump contacts the second push rod 35, the second push rod 35 begins to move downward, and the second spring 34 is compressed. The first spring 21, under the reaction force of the second spring 34, begins to slowly contract, and the first push rod 32 also begins to slowly move downward. When the small O-ring contacts the bottom of the first push rod 32, the downward movement of the small O-ring is restricted. As it continues to move downward, the bottom of the first push rod 32 can press the small O-ring into place. As the first push rod 32 continues to move downward, when the large O-ring contacts the top of the limiting block 22, the downward movement of the large O-ring is restricted, and the limiting block 22 can press the large O-ring into place. Finally, both the large and small O-rings are pressed into place. Since the tooling is placed horizontally, the large and small O-rings are pressed into place through the horizontal plane, so the force is uniform. After the O-rings are pressed into place, they are not easy to rebound, thereby improving the pass rate of "installation in place test" and reducing the risk of ring clamping during press-fitting.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
