[0033] When testing the torque value of a torque wrench within the industry, there are strict requirements on the position where the lever abuts against the handle of the torque wrench. The lever can only abut against the center position of the handle along its length, but this center position can have a certain tolerance range. Therefore, this center position and its tolerance range are defined as the center area.
[0034] Please refer to Figure 1-Figure 7 , an embodiment of the present application discloses a torque wrench 200 detection device 100 .
[0035] In one embodiment, if Figure 1-Figure 4 As shown, the torque wrench 200 detection device 100 includes a host computer, a test bench 10, a test seat 20 and an adjustment mechanism 30. The host computer is used to receive and process data. There is at least one test seat 20, which is fixed on the test bench 10. The test seat 20 includes a fixed sleeve (not shown) and a torque sensor (not shown). One end of the fixed sleeve is fixed on the test bench 10, and the inner hole of the fixed sleeve is connected with the test bench 10. The other end of the fixed sleeve protrudes from the test bench 10 and is used to sleeve and fix the working end 202 of the torque wrench 200. The torque sensor is arranged in the fixed sleeve, and the working end 202 is embedded in the fixed sleeve and connected to the torque sensor, so that the torque sensor can sense the torque value output by the wrench, and send the sensed torque value to the host computer. The host computer analyzes and processes the torque value according to a preset program, and compares whether the torque value output by the torque wrench 200 and the preset value are within the error range, that is, whether the torque of the torque wrench 200 meets the production requirements.
[0036] The adjustment mechanism 30 includes a first telescopic component 31, a second telescopic component 32, an abutment seat 33 and a driving member 34. The first telescopic component 31 slides through a side wall of the test bench 10 and enters the interior of the test bench 10, so that the first telescopic component 31 can perform reciprocating telescopic motion along the length direction of the test bench 10. When not working, the first telescopic component 31 can be pushed closer to the test bench 10, so that the torque wrench 200 detection device 100 has a compact structure, a small volume, and saves space. At the same time, when the torque value of the torque wrench 200 to be detected is relatively large, the first telescopic component 31 can be pulled out in a direction away from the test seat 20 for use, wherein the length direction of the test bench 10 is the X direction, the width direction of the test bench 10 is the Z direction, and the height direction of the test bench 10 is the Z direction.
[0037] The second telescopic assembly 32 includes a mounting seat 321 and a first telescopic member 322. The mounting seat 321 can be slidably arranged on the first telescopic assembly 31. The first telescopic member 322 can be telescopically arranged on the mounting seat 321. The first telescopic member 322 and the mounting seat 321 are slidably connected, that is, the first telescopic member 322 can slide on the mounting seat 321 to perform telescopic movement, so the first telescopic member 322 can perform telescopic movement along the X direction. Specifically, the first telescopic member 322 is a strip structure.
[0038] The abutment seat 33 includes a shift rod 331 and a support plate 332, one end of the shift rod 331 is vertically fixed on the first telescopic member 322, one end of the support plate 332 is provided with a through hole, and is mounted on the shift rod 331 through the through hole, the support plate 332 and the shift rod 331 form a right angle θ, the angle θ can abut the central area L of the handle 201, the central area L is not a precise value, and there can be an appropriate tolerance range. When driven, the angle θ abuts the central area L of the handle 201 to drive the handle 201 to rotate relative to the working end 202, wherein the central area L of the handle 201 refers to the central area L along the length direction of the handle 201.
[0039] The driving member 34 is fixed on the first telescopic assembly 31 and connected to the second telescopic assembly 32. The driving member 34 drives the mounting seat 321 to move, thereby driving the abutment seat 33 fixed on the first telescopic rod to move along the Z direction, thereby causing the torque wrench 200 to rotate around the working end 202.
[0040] In the present embodiment, the adjusting mechanism 30 is mainly used to adjust the abutment seat 33 of the torque wrench 200 detection device 100 to abut against the central area L of the handle 201. Since the first telescopic member 322 can be extended in the same direction as the second telescopic member 32, when the torque wrench 200 with a shorter length is detected, there is no need to laboriously adjust the bulky first telescopic member 31. Only the light first telescopic member 322 needs to be adjusted to abut the abutment seat 33 against the central area L of the handle 201, thereby saving manpower, reducing adjustment time, and improving overall test efficiency. When the torque wrench 200 with a longer length is detected, the first telescopic member 31 needs to be pulled out and the first telescopic member 322 needs to be fine-tuned. 22 can make the abutment seat 33 abut on the central area L of the handle 201; or when the torque wrench 200 is too long, not only the first telescopic assembly 31 is pulled out, but also the first telescopic member 322 is extended along the direction of the first telescopic assembly 31, so as to expand the bearing range of the torque wrench 200 detection device 100 on the handle 201, so that the abutment seat 33 abuts on the central area L of the handle 201. Therefore, the first telescopic member 322 is the range extension of the first telescopic assembly 31 in the X direction, which not only reduces the volume of the torque wrench 200 detection device 100, but also makes the torque wrench 200 detection device 100 suitable for testing torque wrenches 200 of various sizes, thereby greatly improving the versatility.
[0041] In one embodiment, if Figure 5 As shown, the abutment seat 33 is arranged on one end of the first telescopic member 322 adjacent to the test bench 10. In the initial position, the first telescopic component 31 contacts the surface of one side of the test bench 10. When the length of the torque wrench 200 to be tested does not protrude beyond the range of the test bench 10, the first telescopic component 31 is located in the initial position. However, since the length of the torque wrench 200 does not protrude beyond the range of the test bench 10, the abutment seat 33 cannot abut the handle 201. At this time, the first telescopic member 322 can be moved in the X direction and close to the test bench 20, that is, the first telescopic member 322 extends into the test bench 10 and abuts on the central area L of the handle 201, so that the torque wrench 200 detection device 100 is suitable for the detection of torque wrenches 200 of smaller sizes, thereby greatly improving the versatility.
[0042] In another embodiment, Figure 6 As shown, the abutment seat 33 is fixed on the other end of the first telescopic member 322 away from the test bench 10. At this time, the first telescopic member 322 extends the length of the first telescopic member 322 in the X direction to avoid the first telescopic component 31 being made too large, thereby causing the torque wrench 200 detection device 100 to be bulky.
[0043] In one embodiment, if Figure 7As shown, the mounting seat 321 extends along its length direction to form a dovetail groove 323, and the first telescopic member 322 extends along its length direction to form a dovetail protrusion 324 that matches the dovetail groove 323, and the dovetail protrusion 324 is slidably arranged at the dovetail groove 323. The sliding connection between the dovetail groove 323 and the dovetail protrusion allows the first telescopic member 322 to move along the X direction, thereby achieving the expansion and extension of the first telescopic member 322 on the basis of the first telescopic assembly 31, reducing the volume of the torque wrench 200 detection device 100, making its structural design more compact and improving the versatility of the torque wrench 200 detection device 100.
[0044] Specifically, the dovetail groove 323 usually performs mechanical relative motion, and its functions are as follows: the motion accuracy is not only high but also stable; the dovetail groove 323 is usually used in conjunction with the trapezoidal protrusion to play a guiding and supporting role.
[0045] Furthermore, the dovetail protrusion 324 is provided with at least one limiting hole 325 , and the second telescopic mechanism further includes a fastener 326 , which is movably mounted on the mounting seat 321 and passes through the mounting seat 321 to be inserted into the limiting hole 325 .
[0046] Exemplarily, the number of the limiting holes 325 can be 1, 2, 3, 4, 5, 6, 7, 8, etc. First, the first telescopic member 322 is moved according to the actual situation. When it moves to the preset target distance, the movement is stopped, and then the fastener 326 is passed through the limiting hole 325 and tightened. The fastener 326 plays a fixing role. Avoid displacement of the first telescopic member 322 during the movement process, resulting in inaccurate detection. Optionally, the fastener 326 can be a bolt, a screw, or a pin.
[0047] In one embodiment, if Figure 1 , Figure 2 and Figure 5As shown, the first telescopic component 31 includes a second telescopic member 311, a third telescopic member 312 and a slide 313, one end of the second telescopic member 311 and one end of the third telescopic member 312 are horizontally fixed on a side of the slide 313 facing the test bench 10, and the other end of the second telescopic member 311 and the other end of the third telescopic member 312 pass through a wall of the test bench 10 facing the slide 313 and extend into the cavity of the test bench 10. When not working, by pushing the second telescopic member 311 and the third telescopic member 312 into the cavity of the test bench 10, the relative distance between the adjustment mechanism 30 and the test bench 10 is shortened as much as possible, so that the volume of the torque wrench 200 detection device 100 is smaller and the occupied space is reduced. When working and it is necessary to detect the torque of the torque wrench 200 with a very long length, the second telescopic member 311 and the third telescopic member 312 can be pulled out at the same time to increase the relative distance between the adjustment mechanism 30 and the test bench 10 as much as possible, thereby extending the use range of the torque wrench 200 detection device 100 and improving the versatility of the torque wrench 200 detection device 100.
[0048] Optionally, the second telescopic member 311 and the third telescopic member 312 may both be rod-shaped structures.
[0049] Furthermore, at least one first guide block (not shown) is arranged on the sliding track of the second telescopic member 311 in the test bench 10, and the first guide block is used to guide the second telescopic member 311. At least one second guide block (not shown) is arranged on the sliding track of the third telescopic member 312 in the test bench 10. Both the first guide block and the second guide block are block structures with through holes, so that the first telescopic member 322 can pass through the first guide block and slide in the first guide block, and the second telescopic member 311 can pass through the second guide block and slide in the first guide block. Sliding in the second guide block, the other end of the second telescopic member 311 slides through a side wall of the test bench 10 and the first guide block in sequence, and the other end of the third telescopic member 312 slides through a side wall of the test bench 10 and the second guide block in sequence, so that the adjustment mechanism 30 can be telescopic, thereby improving the convenience of use. The first telescopic component 31 is used to adjust the relative distance between the test bench 10 and the adjustment mechanism 30, and the second telescopic component 32 can be slidably set on the slide 313, and the abutment portion is set on the second telescopic component 32, thereby adjusting the relative distance between the test bench 10 and the abutment portion.
[0050] Furthermore, the first telescopic assembly 31 also includes a transmission member 314 and a slider 315. The transmission member 314 is arranged in the slide 313 and is connected to the driving member 34. The slider 315 is slidably arranged on the transmission member 314. The mounting seat 321 is arranged on the slider 315. The slide 313 is provided with a slide groove 316 extending along its length direction. The slide 313 is provided with a through groove extending along its length direction, and the slide groove 316 and the through groove are connected. The transmission member 314 is fixed at the connection point of the slide groove 316 and the through groove along the length direction of the slide 313. The transmission member 314 passes through the through hole of the slider 315, so that the transmission member 314 can drive the slider 315 to rotate around the working end 202 during transmission, thereby driving the second telescopic assembly 32 fixed on the slider 315 to rotate around the working end 202, and then the second telescopic assembly 32 drives the abutment seat 33 fixed thereon to rotate around the working end 202, thereby realizing the detection of the torque wrench 200. Furthermore, the slide groove 316 and the through groove are beneficial to heat dissipation of the transmission member 314 .
[0051] Exemplarily, the transmission member 314 may be a screw rod, and the driving member 34 may be a servo motor or a stepper motor, etc. The servo motor or the stepper motor drives the screw rod to drive, and the screw rod drives and drives the sliding movement, and the slider 315 moves to drive the working end 202 of the abutment portion to rotate. When the central area L of the handle 201 of the torque wrench 200 abuts on the abutment portion, the abutment portion drives the handle 201 of the torque wrench 200 to rotate around the working end 202. The electric drive improves the intelligence and work efficiency of the torque wrench 200 detection device 100; when the torque wrench 200 rotates to When the preset value is reached, a clicking sound is emitted. At this time, the torque sensor senses the torque value output by the torque wrench 200 and transmits the torque value to the host computer. The host computer analyzes and processes the torque value according to the preset program, and compares whether the torque value output by the torque wrench 200 and the preset value are within the error range, that is, whether they meet the production requirements. Before the detection, a preset value is input into the host computer, and the host computer controls the movement of the driving member 34 according to the preset value. When the torque wrench 200 reaches the preset value during the rotation process, a clicking sound is emitted, so that the torque sensor can sense the torque value output by it.
[0052] In summary, the present application not only expands the range of motion of the adjustment mechanism 30 in the X direction and reduces the volume of the torque wrench 200 detection device 100 by setting the second telescopic component 32 on the first telescopic component 31, but also makes the torque wrench 200 detection device 100 suitable for testing torque wrenches 200 of various sizes, greatly improving versatility. At the same time, when testing a torque wrench 200 with a shorter length, there is no need to laboriously adjust the bulky first telescopic component 31. Only the light first telescopic member 322 needs to be adjusted to abut the abutment seat 33 against the central area L of the handle 201, saving manpower, reducing adjustment time, and improving overall test efficiency.
