A torque value detector that is easy to limit

Abstract

This utility model relates to the field of testing instrument technology, specifically a torque value testing instrument for easy positioning. It includes: a device body comprising a chassis, a worktable connected to one side of the chassis surface, a lead screw inserted inside the worktable, a support frame sleeved on the outer wall of the lead screw, and a positioning rod inserted inside the top of the support frame; a limiting structure, including a first bearing, is connected to the outer surface of the first bearing, and a support plate is connected to the outer surface of the first bearing. This utility model, by pulling the limiting screw, causes the fixing ring to compress the support spring, thereby causing the bottom end of the limiting screw to disengage from the limiting groove in the support frame. After the movement is completed, the bottom end of the limiting screw is inserted into another set of limiting grooves in the support frame, thus limiting the positioning rod. This avoids the problem of wear on the screw hole caused by misalignment of the screw, and the inconvenience of multiple rotations required for screw-based limiting, which is not convenient for quick positioning.

Description

Technical Field

[0001] This utility model relates to the field of testing instrument technology, specifically a torque value testing instrument that is easy to limit. Background Technology

[0002] A torque tester's primary function is to determine the tightness or torsional resistance of an object by measuring the torque it experiences when subjected to torsion. This testing method is crucial for ensuring product safety and reliability, especially in fields such as industrial manufacturing, automotive repair, aerospace maintenance, tool and cutting tool manufacturing, construction and engineering, and research and development. Torque testing ensures that fasteners' torque meets design requirements, thereby preventing equipment failures or safety accidents caused by improper tightening.

[0003] When using existing torque testers, their function is to determine the tightness or torsional resistance of an object. However, the existing torque tester uses screws to limit the positioning rod. This method requires a large number of screw holes to limit the screws. However, if the screws are not properly aligned, the screw holes will wear. In addition, using screws for limiting requires multiple rotations, which is not convenient for quick limiting. Utility Model Content

[0004] The purpose of this utility model is to provide a torque value tester that is easy to limit, so as to solve the problem mentioned in the background art that the existing torque value tester positioning rod limit method uses screws for limit. This method requires a large number of screw holes to limit the screws, but the screws are not aligned properly, which will cause wear on the screw holes. Moreover, the screw limit method requires multiple rotations, which is not convenient for quick limit.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a torque value detector that facilitates limiting, comprising:

[0006] The device body includes a chassis, a workbench is connected to one side of the chassis, a lead screw is inserted inside the workbench, a support frame is sleeved on the outer wall of the lead screw, and a positioning rod is inserted inside the top of the support frame;

[0007] The outer surface of the positioning rod is connected to a limiting structure, including a first bearing, a support plate is connected to the outer surface of the first bearing, a limiting screw is inserted inside the support plate, a fixing ring is connected to the outer surface of the limiting screw, and a support spring is connected to the top of the fixing ring.

[0008] Preferably, the top end of the support spring is connected to the bottom surface of the support plate, and the support plate and the limiting screw are elastically connected by the support spring.

[0009] Preferably, the support plate has a through hole on its surface, the limiting screw is inserted into the through hole of the support plate, and the positioning rod and the support plate are movably connected by a first bearing.

[0010] Preferably, a plurality of limiting grooves are provided on one side of the top surface of the support frame, and the bottom end of the limiting screw is inserted into the limiting groove provided in the support frame.

[0011] Preferably, an adjustment mechanism is connected to one side of the support frame. The adjustment mechanism includes a limit ring, an adjustment screw is inserted inside the limit ring, one end of the adjustment screw is movably connected to a second bearing, and one end of the second bearing is connected to a limit plate.

[0012] Preferably, a movable groove is provided on one side of the inner wall of the support frame, and the limiting plate is inserted into the movable groove of the support frame and slidably connected to the support frame. A groove is provided on one side of the positioning rod, and one end of the limiting plate is inserted into the groove of the positioning rod.

[0013] Preferably, the inner surface of the limiting ring is provided with threads, and the limiting ring and the adjusting screw are rotatably connected by the threads. A slot is opened on one side of the support frame, and one end of the adjusting screw passes through the limiting ring and is inserted into the slot of the adjusting screw and connected to the second bearing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By pulling the limiting screw, the fixing ring is compressed and the support spring is contracted, thereby causing the bottom end of the limiting screw to disengage from the limiting groove in the support frame. Then, the position of the positioning rod is moved so that the bottom end of the positioning rod moves inside the support frame. The first bearing is used to ensure that the angle of the positioning rod does not affect the angle of the support plate when the angle changes. After the movement is completed, the limiting screw is released, and the support spring supports the fixing ring and the limiting screw to reset, so that the bottom end of the limiting screw is inserted into another set of limiting grooves in the support frame. This achieves the limitation of the positioning rod, avoiding the wear of the screw hole caused by misalignment of the screw, and the problem that using screw limitation requires multiple rotations, which is not convenient for quick limitation.

[0016] 2. By rotating the adjusting screw, it moves inside the limiting ring. The second bearing ensures that the rotation of the adjusting screw does not affect the angle of the limiting plate. As the adjusting screw moves, it also causes the limiting plate to be inserted into the groove of the positioning rod, thus limiting the bottom end of the positioning rod and keeping it always inside the support frame. This prevents the positioning rod from detaching from the support frame during movement. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A torque value detector that facilitates limit setting includes:

[0026] The device body 1 includes a chassis 11. A workbench 12 is connected to one side of the surface of the chassis 11. A lead screw 13 is inserted inside the workbench 12. A support frame 14 is sleeved on the outer wall of the lead screw 13. A positioning rod 15 is inserted inside the top of the support frame 14. The internal material of the positioning rod 15 is existing technology and can be purchased on the market. It is not considered as a technical protection point of this application. Therefore, no further details are made.

[0027] The outer surface of the positioning rod 15 is connected to a limiting structure 2, including a first bearing 21. The outer surface of the first bearing 21 is connected to a support plate 22. A limiting screw 23 is inserted inside the support plate 22. A fixing ring 24 is connected to the outer surface of the limiting screw 23. A support spring 25 is connected to the top of the fixing ring 24.

[0028] Furthermore, the top end of the support spring 25 is connected to the bottom surface of the support plate 22, and the support plate 22 and the limiting screw 23 are elastically connected by the support spring 25, thereby realizing the elastic connection between the support plate 22 and the limiting screw 23 through the support spring 25.

[0029] Furthermore, the support plate 22 has a through hole on its surface, and the limiting screw 23 is inserted into the through hole of the support plate 22. The positioning rod 15 and the support plate 22 are movably connected by the first bearing 21, so that the positioning rod 15 and the support plate 22 will not affect each other's angle through the first bearing 21.

[0030] Furthermore, multiple sets of limiting grooves are provided on one side of the top surface of the support frame 14, and the bottom end of the limiting screw 23 is inserted into the limiting groove provided in the support frame 14, so as to limit the bottom end of the limiting screw 23 through the limiting groove provided in the support frame 14.

[0031] Furthermore, an adjustment mechanism 3 is connected to one side of the support frame 14. The adjustment mechanism 3 includes a limit ring 31, and an adjustment screw 32 is inserted inside the limit ring 31. One end of the adjustment screw 32 is movably connected to a second bearing 33, and one end of the second bearing 33 is connected to a limit plate 34, so that the bottom end of the positioning rod 15 is always located inside the support frame 14.

[0032] Furthermore, a movable groove is provided on one side of the inner wall of the support frame 14, and the limiting plate 34 is inserted into the movable groove of the support frame 14 and slidably connected to the support frame 14. A groove is provided on one side of the positioning rod 15, and one end of the limiting plate 34 is inserted into the groove of the positioning rod 15, so that one end of the limiting plate 34 is positioned by the groove of the positioning rod 15.

[0033] Furthermore, the inner surface of the limiting ring 31 is provided with threads, and the limiting ring 31 and the adjusting screw 32 are rotatably connected by the threads. A slot is opened on one side of the support frame 14, and one end of the adjusting screw 32 passes through the limiting ring 31 and is inserted into the slot of the adjusting screw 32 and connected to the second bearing 33, so that the angle of the limiting plate 34 is not affected when the adjusting screw 32 rotates through the second bearing 33.

[0034] Working principle: When the torque value tester limits the workpiece, the limiting screw 23 is pulled to compress the support spring 25 by the fixed ring 24, thereby causing the bottom end of the limiting screw 23 to disengage from the limiting groove of the support frame 14. Then, the position of the positioning rod 15 is moved so that the bottom end of the positioning rod 15 moves inside the support frame 14. The first bearing 21 is used to ensure that the angle of the positioning rod 15 does not affect the angle of the support plate 22 when the angle changes. After the movement is completed, the limiting screw 23 is released, and the support spring 25 supports the fixed ring 24 and the limiting screw 23 to reset, so that the bottom end of the limiting screw 23 is inserted into another set of limiting grooves in the support frame 14, thereby limiting the positioning rod 15.

[0035] When adjusting the torque value detector that facilitates positioning, the adjusting screw 32 is rotated to move inside the limiting ring 31. The second bearing 33 ensures that the rotation of the adjusting screw 32 does not affect the angle of the limiting plate 34. As the adjusting screw 32 moves, it drives the limiting plate 34 to be inserted into the groove of the positioning rod 15, thus limiting the bottom end of the positioning rod 15. This ensures that the bottom end of the positioning rod 15 is always inside the support frame 14, preventing the positioning rod 15 from detaching from the support frame 14 during movement.
