[0033] The conventional clamping methods currently available on the market mainly include arranging tensioning support points at the BOSS column position, and clamping through quick clamps, spring clamping, and spring clip clamping.

[0034] In the related technology, with the continuous upgrading and modification of automobile models, the requirements for automobile interior are getting higher and higher, and the use of coated surfaces is becoming more and more frequent, so the requirements for inspection of gauges, fixtures, and tooling, the protection of the surface of parts, the detection space, and the operating performance need to spend a lot of cost. In the past, the commonly used conventional pressure heads of inspection gauges, fixtures, and tooling were directly pressed on the surface of the product. When encountering the special shape of the product, the pressure head often needs to be processed according to the shape. At the same time, it will bring irreversible indentation, wear and tear to the surface of the coated parts, and occupy the measurement space, which greatly reduces the utilization rate of the product and greatly increases the scrap rate.

[0035] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a Boss column positioning rib tensioning mechanism. When it is needed, it is only necessary to rotate the push-pull quick clamp 6 to rotate the screw 4 to adjust the position of the base 3. When the base 3 moves forward, the BOSS is loosened, and when it moves backward, the BOSS column is tightened. It is more convenient and quick, and improves the practicality of the device.

[0036] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0037] Combination Figure 1-Figure 4 The embodiment of the present application provides a Boss column positioning rib tensioning mechanism, including a reference block 1, a base 3 is provided on the reference block 1, a through hole is opened inside the base 3, a clamping sleeve 2 and a screw 4 are installed in the through hole, the screw 4 is threadedly connected in the clamping sleeve 2, a limit pin 7 is provided on the base 3, the limit pin 7 passes through the clamping sleeve 2, a bending part 5 is provided on the screw 4, a push-pull quick clip 6 is provided on the bending part 5, and the push-pull quick clip 6 is fixedly connected to one end of the screw 4.

[0038] When in use, after fixing the bending part 5 in the specified position by bolts, turn the handle on the push-pull quick clamp 6 to make the push-pull quick clamp 6 drive the screw rod 4 to rotate, and one end of the screw rod 4 is rotatably connected to the reference block 1, and the clamping sleeve 2 is threadedly connected to the screw rod 4, so that the clamping sleeve 2 drives the base 3 to move. When the base 3 moves forward, release the BOSS, and when the base 3 moves backward, tighten the BOSS column. By rotating the push-pull quick clamp 6 forward and reversely pushing and pulling the quick clamp 6, the base 3 can be adjusted forward and backward. Since the clamping sleeve 2 is threadedly connected, the number of thread turns is not highly restrictive on the position, and there will be a certain front and rear error. Therefore, two limit pins 7 are passed through the four opening positions around the clamping sleeve 2 to limit its rotation with a certain probability due to the connecting thread, thereby preventing interference and other problems caused by rotation.

[0039] In some embodiments, a plurality of limiting pins 7 are provided to improve the limiting effect.

[0040] In some embodiments, the bending member 5 is in a stepped shape for easy installation.

[0041] In some embodiments, a protection assembly 8 is provided on the base 3; the protection assembly 8 includes: a cylinder 1 81, which is provided on the base 3; a cylinder 2 82, which is slidably connected to the cylinder 1 81; a cylinder 3 83, which is slidably connected to the cylinder 2 82, and one end of the cylinder 3 83 is connected to the bending part 5.

[0042] During use, when the base 3 slides, the barrel 1 81 and the barrel 2 82 are pulled out from the barrel 3 83 , or the barrel 3 83 and the barrel 2 82 are slid into the barrel 1 81 , so as to cover and protect the screw 4 .

[0043] In some embodiments, the protection component 8 also includes: a slider 84, which is opened on the cylinder one 81 and the cylinder two 82; a slide groove 85, which is fixedly connected to the cylinder two 82 and the cylinder three 83, and the slide groove 85 is slidably connected to the slider 84. When in use, the cylinder two 82 and the cylinder three 83 drive the slider 84 to slide in the slide groove 85 to prevent the cylinder one 81, the cylinder two 82 and the cylinder three 83 from detaching.

[0044] In some embodiments, the slider 84 penetrates the cylinder 1 81 and the cylinder 2 82 to allow air to circulate between the inside of the cylinder 1 81 and the cylinder 2 82 and the outside.

[0045] In some embodiments, the cylinder 1 81 and the cylinder 3 83 are respectively fixedly connected to the base 3 and the bending part 5 by bolts, so as to facilitate the disassembly of the protection component 8.

[0046] In some embodiments, the cross-sections of the cylinder 1 81 , the cylinder 2 82 , and the cylinder 3 83 are all rectangular, so that the cylinder 1 81 can be tightly attached to the base 3 .
