DETAILED DESCRIPTION
[0031] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.
[0034] like Figure 1-5 As shown, the utility model specifically relates to a manual calibration device for a torque tool, comprising a vehicle body frame 100, wherein the vehicle body frame 100 is provided with a torque calibration mechanism 200 and a power mechanism 300;
[0035] The torque calibration mechanism 200 includes a bearing plate 210 fixed to the vehicle body frame 100 and a torque sensor 220 disposed on the bearing plate 210, wherein the upper end surface of the torque sensor 220 is connected to one end of a torque tool;
[0036] The power mechanism 300 includes a transverse linear translation module 310, a longitudinal linear translation module 320 arranged on the transverse linear translation module 310, and a gear rod 330 arranged on the longitudinal linear translation module 320. The transverse linear translation module 310 drives the gear rod 330 to abut against the other end of the torque tool, and drives the gear rod 330 to move through the longitudinal linear translation module 320 to complete the torque test.
[0037] It should be noted that, first, the tightening end of the torque tool is placed on the torque sensor 220, and the relative positions of the gear lever 330 and the vehicle body frame 100 are adjusted by the lateral linear translation module 310, so that the gear lever 330 is in contact with the handle end of the torque tool. At this time, the relative positions of the gear lever 330 and the vehicle body frame 100 are adjusted by the longitudinal linear translation module 320, and an external force is applied to the handle of the torque tool through the gear lever 330. After the arm applies the external force, the tightening end of the torque tool will not move, and the torque data is collected through the torque sensor 220 to complete the test.
[0038] Since torque tools come in many sizes and specifications, in order to ensure that the position of the torque tool does not change during the test, the gear rod 330 is moved to a suitable position through the lateral linear translation module 310 to ensure that the gear rod 330 can abut against the handle of the torque tool so as to apply external force to the handle to complete the test.
[0039] The longitudinal linear translation module 320 includes a slide platform 321 and a connection component used in conjunction with the slide platform 321 . The shift rod is disposed on the connection component and can be longitudinally translated through the slide platform 321 .
[0040] The connecting component is arranged in the slide platform 321 and can move linearly along the length direction of the slide platform 321. When the connecting component moves, it can drive the gear rod 330 to move, and then apply external force to the torque tool handle abutting against the gear rod 330 to complete the torque test.
[0041] The connecting assembly includes a screw rod 323 arranged on the slide platform 321 and a sleeve 322 used in conjunction with the screw rod 323, the shift rod 330 is arranged on the sleeve 322, and a hand-cranked wheel 324 is arranged at one end of the screw rod 323 passing through the slide platform 321, and the hand-cranked wheel 324 drives the screw rod 323 to rotate, thereby driving the shift rod 330 located on the sleeve 322 to translate longitudinally.
[0042] The sleeve 322 is sleeved on the surface of the screw 323. When the screw 323 rotates, the sleeve 322 moves linearly synchronously. The cooperation between the screw 323 and the sleeve 322 can improve the accuracy of movement, thereby ensuring the stability of the test. The continuity and stability of the external force applied to the handle end of the torque tool is achieved through the gear rod 330.
[0043] A follow-up protection rod 340 is sleeved on the surface of the gear lever 330 and fixed by an embossed knob. The follow-up protection rod 340 can move along the axial direction of the gear lever 330 .
[0044] Among them, the follow-up protection rod 340 includes an upper cross bar 341, a lower cross bar 343 and a connecting rod 342. One end of the upper cross bar 341 and the lower cross bar 343 are respectively sleeved on the surface of the gear rod 330 and can move along the axial direction of the gear rod 330; the other end of the upper cross bar 341 and the lower cross bar 343 are fixed by the connecting rod 342.
[0045] When the gear rod 330 abuts against the handle end of the torque tool, the handle end of the torque tool passes through the opening formed between the follow-up protection rod 340 and the gear rod 330. At this time, the lower end surface of the handle end of the torque tool abuts against the lower cross bar 343, and the handle end of the torque tool is supported by the lower cross bar 343 to ensure that the upper end surface of the torque tool is in a horizontal state during the test, thereby ensuring the test accuracy and preventing the tightening end from falling off.
[0046] Similarly, the follower protection rod 340 can be adjusted according to the specifications of the torque tool. The follower protection rod 340 can move up and down or rotate along the axis of the gear rod 330, and finally fixed in position by an embossed knob to ensure that the position of the follower protection rod 340 will not change.
[0047] A follower bearing 360 is sleeved on the surface of the shift rod 330 , wherein the follower bearing 360 is located above the lower cross bar 343 and is always in contact with the lower cross bar 343 .
[0048] The transverse linear translation module includes a guide rail platform 311 and a slide table 312 used in conjunction with the guide rail platform 311 , and the longitudinal linear translation module 320 is fixed to the end of the slide table 312 .
[0049] It also includes a stopping mechanism 350 arranged on the slide 312, and the stopping mechanism 350 includes a shell 351 and a pressure block 352, and the pressure block 352 is assembled in the shell 351; there is also an embossed knob for driving the pressure block 352 to move, and the embossed knob drives the pressure block 352 to move vertically up and down in the shell 351 to abut or separate from the guide rail platform 311.
[0050] When it is necessary to adjust the position of the slide 312 relative to the guide rail platform 311, the embossed knob is used to drive the pressure block 352 to move upward relative to the shell 351, so that the pressure block 352 is separated from the guide rail platform 311. At this time, the slide 312 can move along the length direction of the guide rail platform 311; when it is necessary to fix the position, the embossed knob is used to drive the pressure block 352 to move downward relative to the shell 351, so that the pressure block 352 is in contact with the guide rail platform 311. At this time, the slide 312 cannot move.
[0051] The torque sensors 220 are provided in multiple groups, and the multiple groups of torque sensors 220 have the same structure and different torque calibration ranges, so as to be applicable to torque tests of different specifications and have a wide range of applications.
[0052] The vehicle body frame 100 is further provided with a computer keyboard and mouse control component 120 , and the computer keyboard and mouse control component 120 is electrically connected to the torque sensor 220 .
[0053] The bottom of the body frame 100 is also provided with running wheels 110 to facilitate the movement of the equipment.
