Description

Technical Field

[0001] This utility model belongs to the technical field of valve assembly equipment, specifically a spring mounting device for valve body assembly. Background Technology

[0002] Cooling systems for electronic devices such as servers require high-precision valves to control coolant flow. Currently, the valve seat, spring, and retaining ring are installed by using a moving assembly and grippers to place the spring and retaining ring inside the valve seat, and then pressing them down with the moving assembly and grippers. However, the moving assembly, grippers, and valve seat have poor resistance to lateral deviation. During the pressing process, the spring and valve seat are prone to lateral deviation, scratching the inner wall of the valve seat, resulting in a decrease in the sealing performance of the assembled valve body, which fails to meet the requirements of high-reliability cooling systems. Utility Model Content

[0003] The purpose of this utility model is to provide a spring mounting device for valve body assembly. After positioning the valve seat using a press with strong anti-lateral deviation capability, the spring and retaining ring are pressed into the valve seat, reducing the probability of the spring and valve seat lateral deviation scratching the inner wall of the valve seat. This solves the problem in the prior art where the spring lateral deviation easily scratches the inner wall of the valve seat, leading to a decrease in the sealing performance of the assembled valve body.

[0004] The technical solution of this utility model is as follows: the spring mounting device for valve body assembly includes: a spring feeding mechanism, a snap ring washer feeding mechanism, a valve seat feeding mechanism, and a press.

[0005] The press includes a valve seat positioning mechanism, a lifting positioning mechanism, and a pressing mechanism. The valve seat positioning mechanism is located below the lifting positioning mechanism, and the lifting positioning mechanism is located below the pressing mechanism. The lifting positioning mechanism is provided with a guide hole.

[0006] The spring feeding mechanism, the snap ring washer feeding mechanism, and the valve seat feeding mechanism are located on one side of the press.

[0007] The valve seat feeding mechanism is used to place the valve seat on the valve seat positioning mechanism, the spring feeding mechanism is used to place the spring inside the valve seat, and the snap ring washer feeding mechanism is used to place the snap ring inside the guide hole of the lifting and positioning mechanism.

[0008] The lifting and positioning mechanism and the valve seat positioning mechanism are used to position the valve seat, and the pressing mechanism presses the snap ring in the guide hole into the valve seat.

[0009] In a further embodiment, the valve seat positioning mechanism includes: a valve seat positioning fixing component, a valve seat positioning moving component, and a valve seat positioning power source. The valve seat positioning fixing component and the valve seat positioning power source are disposed below the lifting and positioning mechanism, and the valve seat positioning moving component is mounted on the valve seat positioning power source.

[0010] When the valve seat feeding mechanism moves the valve seat between the valve seat positioning fixing part and the valve seat positioning moving part, the valve seat positioning power source drives the valve seat positioning moving part to move towards the valve seat positioning fixing part to apply a clamping force to the valve seat. Compared with the prior art of positioning the valve seat in a fixed hole without applying a clamping force, the valve seat stability is greatly improved by the cooperation of the valve seat positioning fixing part, the valve seat positioning moving part and the valve seat positioning power source.

[0011] In a further embodiment, the press further includes a pressure head.

[0012] The pressure head is installed on the pressing mechanism, which presses the retaining ring into the valve seat through the pressure head.

[0013] In a further embodiment, the lifting and positioning mechanism includes: a lifting power component, a positioning plate, a material blocking power component, and a material blocking component.

[0014] The positioning plate is installed on the lifting power component, the guide hole is opened in the positioning plate, and the lifting power component is used to drive the positioning plate to rise and fall.

[0015] The material blocking power component is mounted on the positioning plate, and the material blocking component is mounted on the material blocking power component.

[0016] When the lifting power component drives the positioning plate to move towards the valve seat, the blocking power component moves the blocking component above the guide hole. The blocking power component enables the blocking component to move between the position above the guide hole and the side position of the guide hole. When the blocking component moves above the guide hole, it can prevent the spring in the valve seat from being pressed to the edge by the positioning plate and then rebounding out of the valve seat.

[0017] In a further embodiment, a positioning protrusion is provided below the positioning plate. When the lifting power component drives the positioning plate to move towards the valve seat to a predetermined position, the positioning protrusion is inserted into the valve seat. The positioning protrusion inserted into the valve seat can improve the valve seat's anti-lateral deviation capability.

[0018] In a further embodiment, the press includes four guide columns, which are disposed at the four corners of the lifting and positioning mechanism and the pressing mechanism.

[0019] In a further embodiment, the guide hole is a frustum-shaped hole that is larger at the top and smaller at the bottom.

[0020] In a further embodiment, the spring feeding mechanism includes: a spring vibratory plate, a spring moving assembly, and two spring grippers.

[0021] The spring moving assembly is located on one side of the spring vibrating plate, and the two spring grippers are mounted on the spring moving assembly.

[0022] The spring vibratory plate is used to transport the spring to the working position of the spring gripper. The spring moving assembly moves the vertical spring to above the valve seat through the spring gripper, which can reduce the friction between the spring and the valve seat, further reducing the probability of the spring scratching the inner wall of the valve seat. Moreover, through the cooperation of the spring moving assembly and the two spring grippers, one gripper can move the spring to above the valve seat while the other empty gripper moves from above the valve seat to the position to cooperate with the spring vibratory plate to obtain the spring, reducing the waiting time for other processes in valve seat assembly.

[0023] In a further embodiment, the snap ring washer feeding mechanism includes: a snap ring vibratory feeder, a washer vibratory feeder, a snap ring moving assembly, snap ring grippers, and washer grippers.

[0024] The snap ring moving assembly is located on one side of the snap ring vibratory plate and the shim vibratory plate. The snap ring gripper and the shim gripper are installed on the snap ring moving assembly. The snap ring moving assembly uses the snap ring gripper and the shim gripper to move the snap ring and the shim to the guide hole of the lifting and positioning mechanism.

[0025] In a further embodiment, the valve seat feeding mechanism includes: an indexing plate, a valve seat positioning fixture, a valve seat moving assembly, and two valve seat grippers.

[0026] Multiple valve seat positioning fixtures are installed on an indexing plate, the valve seat moving assembly is located on one side of the indexing plate, and two valve seat grippers are installed on the valve seat moving assembly.

[0027] The spring feeding mechanism is used to place the spring into the valve seat on the valve seat positioning fixture.

[0028] The indexing plate is used to move the valve seat containing the spring to below the valve seat gripper, and the valve seat moving assembly moves the valve seat onto the valve seat positioning mechanism via the valve seat gripper.

[0029] The valve seat moving assembly and the two valve seat grippers work together to move the valve seat from the valve seat positioning fixture to the valve seat positioning mechanism, and from the valve seat positioning mechanism to the valve seat positioning fixture, thus reducing the waiting time for other valve seat assembly processes.

[0030] The beneficial effects of this utility model are as follows: This application uses the cooperation of the spring feeding mechanism, the snap ring washer feeding mechanism and the valve seat feeding mechanism to place the spring, snap ring and valve seat in a position where they can cooperate with each other in the press. Then, the valve seat positioning mechanism and the lifting positioning mechanism cooperate to position the valve seat. Then, a press with strong anti-lateral deviation capability is used to press the snap ring into the valve seat, so that the spring is stuck between the snap ring and the valve seat. At the same time, the probability of the valve seat and spring deviating to the side is reduced, and the probability of the spring and valve seat deviating to the side and scratching the inner wall of the valve seat is reduced. This solves the problem in the prior art that the spring and valve seat deviating to the side and scratching the inner wall of the valve seat will lead to a decrease in the sealing performance of the valve body after assembly.
