Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices, and in particular to an auxiliary device for detecting screw meshing clearance. Background Technology

[0002] The main purpose of screw clearance testing is to ensure the normal operation of screw compressors and optimize their performance. Clearance is the tiny space between the screw and the compressor housing; its size directly affects the compressor's performance and lifespan. When testing the screw clearance with a feeler gauge, an auxiliary device is needed to support the screw.

[0003] While existing auxiliary devices have an arc-shaped groove on top for temporary placement of the screw, they still have other problems during use. For example, they lack a gap adjustment function, making them unsuitable for meshing and aligning screws of different sizes. If the screw is too large, it cannot be inserted; if the screw is too small, it cannot be properly aligned and meshed, resulting in poor flexibility. Furthermore, they cannot clamp and limit the screw end. When the screw is aligned and being tested, if personnel accidentally touch and move or rotate the screw, it will cause a deviation in its original position, requiring readjustment and increasing the workload of personnel. To solve the above problems, we propose an auxiliary device for detecting screw meshing gap. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for detecting screw meshing clearance, which solves the problems of existing auxiliary devices not having a gap adjustment function and being unable to clamp and limit the rod end.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a screw meshing clearance detection auxiliary device includes a first housing, a first bidirectional screw rotatably connected inside the first housing, two first threaded plates threadedly connected to the surface of the first bidirectional screw, a second housing mounted on the top of the first threaded plates, a second bidirectional screw rotatably connected inside the second housing, two second threaded plates threadedly connected to the surface of the second bidirectional screw, a fixed seat mounted on the top of the second threaded plates, a placement groove formed on the top of the fixed seat, a mounting bracket welded to the top of the fixed seat, a threaded rod threadedly connected to the top of the mounting bracket, a limit plate rotatably connected to the bottom of the threaded rod, and a first throttle welded to the top of the threaded rod.

[0006] The above technical solution has the function of pitch adjustment, is suitable for testing screws of different sizes, has good flexibility, and can clamp and limit the rod end. It is simple and convenient to operate, avoids displacement and rotation during the testing process, and has high practicality.

[0007] The present invention is further configured such that the surfaces of the first housing, the second housing, and the fixing base are all coated with anti-corrosion coating.

[0008] By adopting the above technical solution and applying anti-corrosion coating, the anti-corrosion and moisture-proof effects of the first shell, the second shell, and the mounting base can be improved.

[0009] The present invention is further configured such that: a second slide rail is bolted to the inside of the first housing, a second slider is welded to the bottom of the first threaded plate and slidably connected to the second slide rail, a first slide rail is bolted to the inside of the second housing, and a first slider is welded to the bottom of the second threaded plate and slidably connected to the first slide rail.

[0010] By adopting the above technical solution, the first slide rail, the second slider, the first slide rail and the first slider can be set to limit the first threaded plate and the second threaded plate respectively, so as to prevent the first threaded plate from flipping when moving left and right, or the second threaded plate from flipping when moving back and forth.

[0011] The present invention is further configured such that: a second throttle is welded to the other end of the first bidirectional screw, and a third throttle is welded to the other end of the second bidirectional screw.

[0012] By adopting the above technical solution, the setting of the second and third throttles facilitates the rotation of the first or second bidirectional screw by personnel.

[0013] The present invention is further configured such that: mounting plates are symmetrically welded on both sides of the first housing, and mounting holes are provided inside the mounting plates.

[0014] By adopting the above technical solution, the installation plate and mounting holes make it easy for personnel to fix the first housing with screws.

[0015] The present invention is further configured such that a protective pad is installed inside the placement groove.

[0016] By adopting the above technical solution, the end of the screw can be protected by the protective pad, preventing scratches caused by pulling.

[0017] The present invention is further configured such that the fixing base, mounting bracket and limiting plate are all made of stainless steel.

[0018] Using the above technical solution, the fixing seat, mounting bracket and limiting plate have the characteristics of high strength, low density and excellent corrosion resistance.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model involves first holding the second handle to rotate the first bidirectional screw. When the first bidirectional screw rotates, it causes the two first threaded plates and the second housing to move inward synchronously. When the second housing moves, it causes the fixed seat to move as well. After the lateral distance is adjusted, the third handle is held to rotate the second bidirectional screw. When the second bidirectional screw rotates, it causes the two second threaded plates to move closer together. When the second threaded plates move, they cause the fixed seat to move as well. This invention has a spacing adjustment function and is suitable for testing screws of different sizes, offering good flexibility.

[0021] 2. This utility model involves placing two screws into the placement slots in the fixed base from the front and rear directions, respectively. After the screws are placed and their positions are adjusted, the first throttle is held by hand to rotate the screw rod. When the screw rod rotates, it will drive the limiting plate to move downward. When the limiting plate moves downward, it will fix the screw rod, which can clamp and limit the rod end. The operation is simple and convenient, and it avoids displacement and rotation during the testing process, making it highly practical. Attached Figure Description
