Description
Technical Field
[0001] This utility model relates to the field of testing tooling technology, specifically a testing tooling for thread testing. Background Technology
[0002] As a fundamental connecting element in the industrial field, the quality of threads directly affects the safety and performance of equipment. Thread inspection fixtures ensure the interchangeability and assembly reliability of threads by precisely controlling thread parameters (such as pitch diameter, thread pitch, and thread angle). The core function of thread inspection fixtures is to ensure the interchangeability, assembly performance, and safety of use of threads.
[0003] Regarding the above and existing related technologies: During connector production, threads are set on the connector. In order to ensure the quality of the threads, it is necessary to inspect the threads on the connector. Since most inspection fixtures lack adjustment capabilities, they can only inspect connectors of the same specification. When inspecting connectors of different batches and specifications, incompatibility problems are likely to occur. Therefore, an inspection fixture for thread inspection is proposed to address the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The present utility model provides a thread inspection fixture, including a motor, a connector, and a moving device. The output end of the motor is fixedly connected to a detector, and the connector is located directly above the detector. The moving device is disposed on the surface of the motor and the connector. The moving device includes a support frame, which is located directly below the motor. A moving plate is slidably connected to the surface of the support frame. Two clamping plates are rotatably connected to the surface of the moving plate. Each of the two clamping plates has a clamping ring fixedly connected to one end close to the other. The clamping ring is sleeved on the surface of the connector. Pushing the clamping plates causes the clamping plates to move the moving plate. The moving plate slides on the surface of the support frame, and the connector is inserted into the inner surface of the detector. During inspection, the motor drives the detector to rotate. By setting the support frame, the moving plate, the clamping plates, and the clamping ring, the connector can be fixed, and the connector can also be conveniently inspected.
[0006] Preferably, a push handle is fixedly connected to the side wall of the clamping plate. When it is necessary to operate the clamping plate, the push handle is pushed to make the clamping plate rotate. The push handle facilitates the operation of the clamping plate.
[0007] Preferably, a limiting block is fixedly connected to the upper surface of the clamping plate. The limiting block is located on the surface of the connector and moves against the connector. By setting the limiting block, the position of the connector can be restricted.
[0008] Preferably, two main springs are fixedly connected to the ends of the clamps that are close to each other. When the connector is fixed, the main springs will drive the clamps to rotate when the clamps are released. The clamps can be driven to rotate by setting the main springs.
[0009] Preferably, two support blocks are fixedly connected to the surface of the support frame, and two auxiliary springs are fixedly connected to the upper surface of the support blocks and the bottom end of the moving plate. After the test is completed, the moving plate is released, and the auxiliary springs will drive the moving plate to move. By setting the support blocks and auxiliary springs, the moving plate can be driven to move.
[0010] Preferably, a limiting device is provided on the surface of the support frame near the motor. The limiting device includes two fixing rings, the bottom ends of which are fixedly connected to the surface of the support frame. The two fixing rings are sleeved on the surface of the motor. A placement block is fixedly connected to the surface of the two fixing rings. A threaded post is threadedly connected to the inner wall of the placement block. The threaded post is located on the surface of the motor. Rotating the threaded post causes it to rotate on the inner wall of the placement block, with the threaded post pressing against the surface of the motor. By setting the fixing rings, the placement block, and the threaded post, the position of the motor can be limited.
[0011] Preferably, a throttle is fixedly connected to the side wall of the threaded post, and a top plate is fixedly connected to the end of the threaded post away from the throttle. The top plate is located on one side of the motor, and the threaded post drives the top plate to move. The top plate rests on the surface of the motor. By setting the top plate, the contact area between the threaded post and the motor can be increased.
[0012] The advantages of this utility model are: 1. During testing, this utility model involves pushing two push handles to rotate two clamping plates. The clamping plates rotate on the surface of the moving plate, and the rotation of the clamping plates stretches the main spring. After the clamping plates unfold, the connector is placed in the appropriate position. Releasing the push handles causes the main spring to rebound, driving the clamping plates to rotate. The clamping plates move the clamping ring, which clamps the connector surface. When the rotating plate rotates, it also drives the limiting block to rotate, moving the limiting block to the upper surface of the connector. Then, pushing the push handles causes the clamping plates and the moving plate to move. The moving plate moves the connector and slides on the support frame surface. The moving plate causes the secondary spring on the support block to retract. During testing, the motor is started to drive the detector to rotate. When the connector moves, it inserts into the inner wall of the detector. When the threads are compatible, the detector will penetrate deep into the connector. When they are not compatible, the detector will lock the connector. By setting the entire device, the connector can be fixed, and it can also adapt to connectors of different specifications to a certain extent.
[0013] 2. When using the motor, the present invention inserts the motor into the inner surface of the two fixed rings, and then rotates the throttle to make the throttle drive the threaded column to rotate. The threaded column rotates on the inner wall of the placement block, and the threaded column drives the top plate to move. The top plate presses against the surface of the motor. By setting the entire device, the position of the motor can be restricted, reducing the situation of the motor moving randomly during use. Attached Figure Description

[0018] Please see Figure 1-5As shown, a thread inspection fixture includes a motor 1, a connector 3, and a moving device 4. A detector 2 is fixedly connected to the output end of the motor 1, and the connector 3 is located directly above the detector 2. The moving device 4 is disposed on the surfaces of the motor 1 and the connector 3. The moving device 4 includes a support frame 41 located directly below the motor 1. A moving plate 42 is slidably connected to the surface of the support frame 41. Two clamping plates 43 are rotatably connected to the surface of the moving plate 42. A clamping ring 44 is fixedly connected to the end of each clamping plate 43 that is close to each other. The clamping ring 44 is fitted onto... The surface of connector 3; during operation, detector 2 is placed in a suitable position, and then the clamping plate 43 is pushed to rotate on the surface of the moving plate 42. The clamping plate 43 drives the clamping ring 44 to rotate, and the clamping ring 44 clamps the surface of connector 3. Then, the clamping plate 43 is pushed to move the moving plate 42. The moving plate 42 slides on the surface of the support frame 41, and connector 3 will be inserted into the inner surface of detector 2. During detection, motor 1 will drive detector 2 to rotate. By setting support frame 41, moving plate 42, clamping plate 43 and clamping ring 44, connector 3 can be fixed, and connector 3 can also be easily detected.
[0019] A push handle 45 is fixedly connected to the side wall of the clamping plate 43. When working, push the push handle 45 to make the clamping plate 43 rotate. The push handle 45 makes it easy to operate the clamping plate 43.
[0020] The upper surface of the clamping plate 43 is fixedly connected to a limiting block 46, which is located on the surface of the connector 3. During operation, the clamping plate 43 will drive the limiting block 46 to slide, and the limiting block 46 will move against the connector 3. By setting the limiting block 46, the position of the connector 3 can be restricted.
[0021] Two main springs 47 are fixedly connected to one end of the clamping plates 43 that are close to each other. During operation, the clamping plates 43 are pushed to stretch the main springs 47. When the connector 3 is fixed, the clamping plates 43 are released and the main springs 47 drive the clamping plates 43 to rotate. The clamping plates 43 can be driven to rotate by setting the main springs 47.
[0022] Two support blocks 48 are fixedly connected to the surface of the support frame 41. Two auxiliary springs 49 are fixedly connected to the upper surface of the support blocks 48 and the bottom end of the moving plate 42. During operation, the moving plate 42 drives the auxiliary springs 49 to retract. After the test is completed, the moving plate 42 is released, and the auxiliary springs 49 drive the moving plate 42 to move. The moving plate 42 can be driven to move by setting the support blocks 48 and auxiliary springs 49.
[0023] A limiting device 5 is provided on the surface of the support frame 41 near the motor 1. The limiting device 5 includes two fixing rings 51. The bottom ends of the two fixing rings 51 are fixedly connected to the surface of the support frame 41. The two fixing rings 51 are sleeved on the surface of the motor 1. A placement block 52 is fixedly connected to the surface of the two fixing rings 51. A threaded post 53 is threadedly connected to the inner wall of the placement block 52. The threaded post 53 is located on the surface of the motor 1. During operation, the motor 1 is inserted between the inner surfaces of the two fixing rings 51. Then, the threaded post 53 is rotated to rotate on the inner wall of the placement block 52. The threaded post 53 presses against the surface of the motor 1. By setting the fixing rings 51, the placement block 52 and the threaded post 53, the position of the motor 1 can be limited.
[0024] A throttle 54 is fixedly connected to the side wall of the threaded post 53, and a top plate 55 is fixedly connected to the end of the threaded post 53 away from the throttle 54. The top plate 55 is located on one side of the motor 1. During operation, the throttle 54 is rotated to make the threaded post 53 rotate, and the threaded post 53 drives the top plate 55 to move. The top plate 55 rests on the surface of the motor 1. By setting the top plate 55, the contact area between the threaded post 53 and the motor 1 can be increased.
[0025] Working principle: During testing, pushing the two push handles 45 causes the two clamping plates 43 to rotate. The clamping plates 43 rotate on the surface of the moving plate 42. When the clamping plates 43 rotate, they cause the main spring 47 to stretch. After the clamping plates 43 unfold, the connector 3 is placed in the appropriate position. Releasing the push handles 45 causes the main spring 47 to rebound, driving the clamping plates 43 to rotate. The clamping plates 43 drive the clamping ring 44 to move, clamping the connector 3. When the rotating plate rotates, it also drives the limiting block 46 to rotate. The limiting block 46 rotates to the upper surface of the connector 3. Then, pushing the push handles 45 causes the clamping plates 43 and the moving plate 42 to move. The moving plate 42 drives the connector 3 to move. The moving plate 42 also slides on the surface of the support frame 41, driving the support block 48. When the secondary spring 49 contracts, the motor 1 is started during detection, driving the detector 2 to rotate. When the connector 3 moves, it inserts into the inner wall of the detector 2. When the threads are compatible, the detector 2 will penetrate deep into the connector 3. When they are not compatible, the detector 2 will lock the connector 3. By setting the entire device, the connector 3 can be fixed, and it can also adapt to connectors of different specifications to a certain extent. When using the motor 1, the motor 1 is inserted into the inner surface of the two fixing rings 51, and then the handle 54 is turned to drive the threaded post 53 to rotate. The threaded post 53 rotates on the inner wall of the placement block 52, and the threaded post 53 drives the top plate 55 to move. The top plate 55 presses against the surface of the motor 1. By setting the entire device, the position of the motor 1 can be restricted, reducing the possibility of the motor 1 moving randomly during use.
