Description

Technical Field

[0001] This utility model belongs to the field of workbench technology, and specifically relates to a workbench for processing and assembling valve components. Background Technology

[0002] Valve assemblies are core components used to control the flow of fluid or regulate its flow rate. They mainly consist of valve body, valve stem, valve core, seals, packing, etc. A workbench is required for support and placement when assembling valve assemblies.

[0003] The existing workbench consists of support legs under the tabletop and a light fixture on top. Although it has ample space and good load-bearing capacity, there are other problems during use. For example, it does not have a multi-directional rotation function. When assembling the valve body, screws need to be passed through the intersection and fixed with nuts. When using traditional side clamps, the sides and back of the valve body will be obstructed. Therefore, when changing the mounting surface, the components need to be disassembled, adjusted in position, and re-clamped, which is time-consuming and laborious, increases the workload of personnel, and has poor flexibility. Utility Model Content

[0004] The purpose of this utility model is to provide a workbench for processing and assembling valve components. Its advantages are that it can facilitate multi-directional conversion of the mounting surface of the components and has a quick limit function.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a workbench for processing and assembling valve components, comprising a table plate, the top of which is integrally formed with a concave end, an annular guide rail being bolted to the inside of the concave end, a mounting plate being provided on the top of the annular guide rail, a guide block being bolted to the bottom of the mounting plate and slidably connected to the annular guide rail, a bearing plate being provided on the top of the mounting plate, a support plate being symmetrically bolted between the bottom of the bearing plate and the mounting plate, a through groove being provided on the top of the bearing plate, two positioning posts being provided inside the through groove, a fixing frame and a connecting plate being bolted to the inside of the concave end and the bottom of the bearing plate respectively, a limit plate being provided inside the fixing frame, a slot being provided at the bottom of the connecting plate, and a limit spring being bolted between the bottom of the limit plate and the fixing frame through a spring fixing piece.

[0006] The above technical solution facilitates multi-directional conversion of the component mounting surface, improves the user's work efficiency in assembling valve components, effectively positions the valve components to prevent displacement, offers good flexibility, and also has a quick limit function to prevent the valve component nut from rotating along with the lower part when tightening, reducing the pressure burden on personnel and making it highly practical.

[0007] The present invention is further configured such that a bidirectional screw is rotatably connected to one side of the support plate via a bearing, and a throttle is bolted to the other end of the bidirectional screw. Two threaded plates are threadedly connected to the surface of the bidirectional screw, and the top of the threaded plates is welded to the bottom of the positioning post.

[0008] The above technical solution, through the setting of a two-way screw, a throttle, and a threaded plate, allows the user to easily adjust the distance between the two positioning pins, making it suitable for positioning valve assemblies of different specifications.

[0009] The present invention is further configured such that a guide rod is provided through one side of the threaded plate, and both ends of the guide rod are welded to the support plate.

[0010] The above technical solution uses a guide rod to limit the threaded plate and prevent it from flipping over during inward or outward movement.

[0011] The present invention is further configured such that a pull rod is welded to the front of the limiting plate, a sliding groove is provided on the front of the fixing frame, and the other end of the pull rod extends to the outside of the sliding groove.

[0012] The above technical solution allows users to easily pull the limiting plate downwards by using the pull rod and sliding groove.

[0013] The present invention is further configured such that the support plate is made of stainless steel.

[0014] The above technical solution results in a bearing plate with high strength, low density, and excellent corrosion resistance.

[0015] The present invention is further configured such that the limiting spring is made of carbon spring steel.

[0016] Using the above technical solution, the limit spring has the characteristics of excellent mechanical properties, good resistance to spring reduction, low temperature resistance and corrosion resistance.

[0017] In summary, this utility model has the following beneficial effects: 1. First, place the valve body on the support plate, and then place the other components on the platform. After the valve body is placed, position the bottom flange hole on the positioning pin. The distance between the two positioning pins can be adjusted by holding the handle and turning it. When the valve body is placed and the orientation needs to be rotated during the assembly process, hold the support plate and rotate it. When the support plate rotates, it will drive the mounting plate to rotate through the fixation of the support plate. When the mounting plate rotates, it will drive the guide block to rotate together on the ring guide rail. This facilitates the multi-directional conversion of the mounting surface of the components, improves the user's work efficiency in assembling valve components, effectively positions the valve components to prevent displacement, and provides good flexibility. 2. By grasping the lever with one hand and pulling it downwards, the lever will cause the limit plate to move down and retract into the fixed frame. After the limit plate has moved to the bottom, the fixed frame is placed into the recessed end below the connecting plate and fixed with screws. After the fixed frame is fixed, the lever is released. After the lever is released, the internal limit spring will return to its original position. After the limit spring returns to its original position, it will push the limit plate up and insert it into the slot at the bottom of the connecting plate. This provides a quick limit function, preventing the valve assembly nut from rotating along with the lower part when tightened, reducing the pressure burden on personnel, and making it highly practical.
