Description

Technical Field

[0001] This utility model belongs to the technical field of valve assembly equipment, specifically a valve seat and valve core assembly device. Background Technology

[0002] Cooling systems for electronic devices such as servers require high-precision valves to control coolant flow. Currently, automated installation of the valve seat, spring, and valve core involves using moving components and grippers to place the spring, valve core, and retaining ring into the valve seat, then directly pressing down the retaining ring to fix the spring and valve core between the retaining ring and the valve seat. Because the valve core floats on the spring, the valve core is easily damaged by being pressed to the side during placement and pressing down the retaining ring, resulting in scratches on the valve core and valve seat. This leads to a decrease in the sealing performance of the assembled valve body, making it difficult to meet the requirements of high-reliability cooling systems. Utility Model Content

[0003] The purpose of this utility model is to provide a valve seat and valve core assembly device that allows the positioning component to avoid the valve core during the downward movement of the positioning component, thereby preventing the valve core from being pressed and deflected. This solves the problem that the sealing performance of the valve body after assembly in the prior art is likely to decrease, making it difficult to meet the requirements of a high-reliability cooling system.

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

[0005] The snap ring feeding mechanism and the valve seat feeding mechanism are located on the side of the press.

[0006] The press includes a lifting and positioning mechanism and a pressing mechanism, wherein the lifting and positioning mechanism is located below the pressing mechanism.

[0007] The lifting and positioning mechanism includes: a lifting power component, a lifting plate, a positioning power component, and a positioning component.

[0008] The lifting plate is installed on the lifting power component, the positioning power component is installed on the lifting plate, and the two positioning components are installed on the positioning power component. The lifting power component is used to drive the lifting plate to rise and fall.

[0009] The valve seat feeding mechanism is used to move the valve seat containing the spring and valve core to below the lifting and positioning mechanism. When the lifting power component drives the positioning component to move to the position that matches the valve core, the positioning power component drives the two positioning components to surround and form a guide hole above the valve seat.

[0010] The snap ring feeding mechanism is used to place the snap ring in the guide hole, and the pressing mechanism is used to press the snap ring in the guide hole into the valve seat.

[0011] In a further embodiment, positioning protrusions are provided below the two positioning members.

[0012] When the two positioning elements are closed to form a guide hole, the positioning protrusions of the two positioning elements are used to apply a clamping force to the valve seat.

[0013] In a further embodiment, the guide hole is a frustum-shaped hole that is larger at the top and smaller at the bottom.

[0014] In a further embodiment, the positioning power component includes a gripper cylinder mounted on the lifting plate, and two positioning components are mounted on the gripper cylinder.

[0015] In a further embodiment, the press further includes a valve seat positioning mechanism.

[0016] The valve seat positioning mechanism is located below the lifting and positioning mechanism.

[0017] The valve seat feeding mechanism is used to move the valve seat containing the spring and valve core onto the valve seat positioning mechanism, which is used to apply a clamping force to the valve seat.

[0018] 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.

[0019] 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.

[0020] In a further embodiment, the valve seat feeding mechanism includes: a valve seat moving assembly and a valve seat gripper.

[0021] The valve seat moving assembly is located on one side of the press, and the valve seat gripper is mounted on the valve seat moving assembly. The valve seat moving assembly moves the valve seat onto the valve seat positioning mechanism through the valve seat gripper.

[0022] In a further embodiment, the valve seat feeding mechanism includes two valve seat grippers.

[0023] The valve seat moving assembly includes a lifting cylinder and a rotating cylinder. The rotating cylinder is mounted on the lifting cylinder, and the two valve seat grippers are mounted on the rotating cylinder. Through the cooperation of the valve seat moving assembly and the two valve seat grippers, the two grippers can simultaneously perform the work of moving the valve seat from the valve seat positioning fixture to the valve seat positioning mechanism, and moving the valve seat from the valve seat positioning mechanism to the valve seat positioning fixture, thereby reducing the waiting time for valve seat assembly.

[0024] In a further embodiment, the snap ring feeding mechanism includes: a snap ring vibratory plate, a snap ring moving assembly, and snap ring grippers.

[0025] The snap ring moving assembly is located on one side of the snap ring vibratory plate, and the snap ring gripper is installed on the snap ring moving assembly. The snap ring moving assembly moves the snap ring, which is transported to a predetermined position by the snap ring vibratory plate, into the guide hole of the lifting and positioning mechanism through the snap ring gripper.

[0026] The beneficial effects of this utility model are as follows: through the cooperation of the lifting power component, the lifting plate, the positioning power component, and the positioning component, the positioning component can avoid the valve core during the downward movement of the positioning component. When the positioning component moves to the position where it mates with the valve core, it surrounds and forms a guide hole to position the snap ring and assemble the snap ring, thus avoiding the valve core being pressed to the side. Compared with the existing technology of directly pressing down to assemble the snap ring, this further reduces the probability of damage to the valve core surface and the inner wall of the valve seat, and solves the problem that the valve body sealing performance is likely to decline after assembly in the existing technology, making it difficult to meet the requirements of a high-reliability cooling system.

[0031] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0032] This utility model discloses a valve seat and valve core assembly device, which is installed inside a valve body assembly equipment. The motor, cylinder, sensor and other components of the valve seat and valve core assembly device are connected to the PLC and other control devices of the valve body assembly equipment. It can make the positioning component avoid the valve core during the downward movement of the positioning component, so as to avoid the valve core being pressed and deflected. This solves the problem that the sealing performance of the valve body after assembly in the prior art is likely to decrease, and it is difficult to meet the requirements of high reliability cooling system.

[0033] like Figure 1 The valve seat and valve core assembly device shown includes: a snap ring feeding mechanism 1, a valve seat feeding mechanism 2, and a press 3.

[0034] The snap ring feeding mechanism 1 and the valve seat feeding mechanism 2 are located on the side of the press 3.

[0035] The press 3 includes a lifting and positioning mechanism 31 and a pressing mechanism 32, with the lifting and positioning mechanism 31 located below the pressing mechanism 32.

[0036] The lifting and positioning mechanism 31 includes: a lifting power component 311, a lifting plate 312, a positioning power component 313, and a positioning component 314.

[0037] The lifting plate 312 is installed on the lifting power component 311, the positioning power component 313 is installed on the lifting plate 312, and two positioning components 314 are installed on the positioning power component 313. The lifting power component 311 is used to drive the lifting plate 312 to lift.

[0038] The valve seat feeding mechanism 2 is used to move the valve seat containing the spring and valve core to below the lifting and positioning mechanism 31. When the lifting power component 311 drives the positioning component 314 to move to the position that mates with the valve core, the positioning power component 313 drives the two positioning components 314 to enclose and form a guide hole 3141 above the valve seat. The position where the positioning component 314 mates with the valve core refers to the position where the positioning component 314 contacts the side of the valve core when the positioning power component 313 drives the two positioning components 314 to enclose and form a guide hole 3141 above the valve seat. Alternatively, the lifting power component 311 can first drive the lifting plate 312, the positioning power component 313, and the positioning component 314 to move downward, and then the positioning power component 313 drives the two positioning components 314 to enclose and form a guide hole 3141 above the valve seat.

[0039] The snap ring feeding mechanism 1 is used to place the snap ring in the guide hole 3141, and the pressing mechanism 32 is used to press the snap ring in the guide hole 3141 into the valve seat. The guide hole 3141 is a frustum hole that is larger at the top and smaller at the bottom, so that the snap ring can gradually shrink and enter the valve seat during the downward movement.

[0040] The pressing mechanism 32 includes a support structure, a pressing cylinder, and a pressing head. The pressing cylinder is installed on the support structure, and the pressing head is installed on the pressing cylinder. The bottom end of the pressing head is a cylindrical structure that cooperates with a snap ring. The pressing cylinder presses the snap ring into the valve seat through the guide hole 3141 via the pressing head. The lifting power component 311 and the lifting plate 312 are installed on the support structure. The lifting plate 312, the positioning power component 313, and the positioning component 314 are located below the pressing cylinder.

[0041] like Figure 3 The two positioning elements 314 shown are provided with positioning protrusions 3142 below them.

[0042] When the two positioning elements 314 surround and form the guide hole 3141, the positioning protrusions 3142 of the two positioning elements 314 are used to apply a clamping force to the valve seat.

[0043] like Figure 1 The positioning power component 313 shown includes a gripper cylinder mounted on the lifting plate 312, and two positioning components 314 mounted on the gripper cylinder.

[0044] like Figure 2 The press 3 shown also includes a valve seat positioning mechanism 33.

[0045] The valve seat positioning mechanism 33 is located below the lifting positioning mechanism 31.

[0046] The valve seat feeding mechanism 2 is used to move the valve seat containing the spring and valve core onto the valve seat positioning mechanism 33, which is used to apply a clamping force to the valve seat.

[0047] like Figure 2 The valve seat positioning mechanism 33 shown includes: a valve seat positioning fixing component 331, a valve seat positioning moving component 332, and a valve seat positioning power source 333. The valve seat positioning fixing component 331 and the valve seat positioning power source 333 are arranged below the lifting positioning mechanism 31, and the valve seat positioning moving component 332 is installed on the valve seat positioning power source 333.

[0048] When the valve seat feeding mechanism 2 moves the valve seat between the valve seat positioning fixing part 331 and the valve seat positioning moving part 332, the valve seat positioning power source 333 drives the valve seat positioning moving part 332 to move towards the valve seat positioning fixing part 331 to apply a clamping force to the valve seat.

[0049] like Figure 1 and 2 The valve seat feeding mechanism 2 shown includes: a valve seat moving assembly 21 and a valve seat gripper 22.

[0050] The valve seat moving assembly 21 is located on one side of the press 3, and two valve seat grippers 22 are installed on the valve seat moving assembly 21. The valve seat moving assembly 21 moves the valve seat onto the valve seat positioning mechanism 33 through the valve seat grippers 22.

[0051] like Figure 1 and 2 The valve seat feeding mechanism 2 shown includes two valve seat grippers 22.

[0052] The valve seat moving assembly 21 includes a lifting cylinder and a rotating cylinder, with the rotating cylinder mounted on the lifting cylinder and two valve seat grippers 22 mounted on the rotating cylinder.

[0053] like Figure 1 The circlip feeding mechanism 1 shown includes: a circlip vibratory plate 11, a circlip moving assembly 12, and a circlip gripper 13.

[0054] The snap ring moving assembly 12 is disposed on one side of the snap ring vibrating plate 11, and the snap ring clamp 13 is installed on the snap ring moving assembly 12. The snap ring moving assembly 12 moves the snap ring that was transported to the predetermined position by the snap ring vibrating plate 11 to the guide hole 3141 of the lifting and positioning mechanism 31 through the snap ring clamp 13.

[0055] The snap ring moving assembly 12 can be a two-axis moving assembly or a three-axis moving assembly. In other embodiments, the snap ring moving assembly 12 and snap ring gripper 13, as well as the valve seat moving assembly 21 and valve seat gripper 22, can be robotic arms.

[0056] Usage method: First, one gripper of the valve seat feeding mechanism 2 moves the assembled valve body off the valve seat positioning mechanism 33, so that the other gripper of the valve seat feeding mechanism 2 moves the valve seat containing the spring and valve core to between the valve seat positioning fixing part 331 and the valve seat positioning moving part 332 below the lifting positioning mechanism 31, so that the valve seat positioning power source 333 drives the valve seat positioning moving part 332 to move towards the valve seat positioning fixing part 331 to apply a clamping force to the valve seat.

[0057] Then, the lifting power component 311 drives the lifting plate 312, the positioning power component 313 and the positioning component 314 to move downward. When the two positioning components 314 move to the position that mates with the valve core, the positioning power component 313 drives the two positioning components 314 to surround and form a guide hole 3141 above the valve seat. At this time, the positioning protrusions 3142 of the two positioning components 314 are used to apply a clamping force to the valve seat.

[0058] Then, the pressing cylinder of the pressing mechanism 32 presses the retaining ring into the valve seat through the guide hole 3141 via the pressing head. Then, the positioning power component 313 drives the two positioning components 314 to move in opposite directions. The lifting power component 311 drives the lifting plate 312, the positioning power component 313 and the positioning components 314 to move upward. The valve seat positioning power source 333 drives the valve seat positioning moving component 332 to move away from the valve seat positioning fixing component 331, so that the gripper of the valve seat feeding mechanism 2 can remove the valve seat on the valve seat positioning mechanism 33.

[0059] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
