Description

Technical Field

[0001] The utility model relates to the technical field of shaft parts detection, in particular to a shaft parts coaxiality detection component. Background Art

[0002] Shaft parts, also known as shaft parts, are one of the typical parts often encountered in hardware accessories. Shaft parts are the connecting parts between the active and driven elements in the mechanical transmission system. They are used to support, transmit power and bear loads. Coaxiality error will affect the assembly accuracy of shaft parts. If the coaxiality error is too large, it will lead to assembly difficulties, unstable transmission, vibration and noise. Therefore, by detecting the coaxiality, problems in the assembly process can be discovered and corrected in time, thereby improving assembly accuracy and efficiency.

[0003] After searching, a Chinese patent with application number CN202320320514.X discloses a coaxiality detection device. During the test, the clamping part needs to clamp or release the axle by turning screws, etc., which makes the test operation complicated and inefficient. Therefore, during the rotation of the workpiece to be measured, it contacts the two supporting groove walls of each positioning groove, thereby limiting the position of the workpiece to be measured. If the coaxiality of the workpiece to be measured is good, the rotation axis of the workpiece to be measured is the axis of the workpiece to be measured. If the coaxiality of the workpiece to be measured is poor, the rotation axis of the workpiece to be measured is always changing. The coaxiality of the component to be measured can be measured by the detection head of the detection component, and the workpiece to be measured is only placed on the positioning groove. The test is simple and convenient, and the test efficiency is improved.

[0004] During the use of the above-mentioned coaxiality detection assembly, it is convenient to perform coaxiality detection on the workpiece to be tested. However, when clamping the shaft part before detection, the existing clamping assembly usually has a fixed size and spacing, and different shaft parts have different sizes and shapes, which makes it inconvenient to adjust according to the length of the shaft part to be detected and the position to be clamped, which reduces the adaptability between the clamping assembly and the shaft part to be tested, and reduces the adjustability of the detection device.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] As attached Figure 1-7 As shown, an embodiment of the utility model provided: a shaft part coaxiality detection component includes a mounting plate 1, a bidirectional screw rod 2 is rotatably connected to the bottom of the mounting plate 1, both ends of the bidirectional screw rod 2 are threadedly connected to a moving plate 3, a plurality of fixed tubes 4 are fixedly connected inside the moving plate 3, an adjusting column 5 is slidably connected inside the fixed tube 4, one end of the adjusting column 5 is threadedly connected to a threaded column 6, one end of the threaded column 6 is rotatably connected to a clamping block 7, a plurality of holes 8 are opened on one side of the adjusting column 5, one end of the fixed tube 4 is fixedly connected to a fixed shell 9, and the fixed shell 9 is slidably connected to a clamping rod 10 A first spring 11 is fixedly connected to the middle of the clamping rod 10, and two stable grooves 12 are provided at the bottom of the mounting plate 1. The bottoms of the two movable plates 3 are slidably connected inside the stable grooves 12. The bidirectional screw rod 2 is convenient for driving the movable plates 3 on both sides to move closer to or away from each other. The adjusting column 5 slides inside the fixed tube 4 to facilitate adjusting the position of the clamping block 7 on the shaft part to be clamped, and then the clamping rod 10 is engaged with the corresponding hole groove 8 to facilitate limiting the adjusted adjusting column 5, and the threaded column 6 is convenient for adjusting the spacing between multiple clamping blocks 7 to adapt to shaft parts of different sizes.

[0033] As attached Figure 1 As shown, a slide groove 20 is provided on the rear side of the mounting plate 1 , the interior of the slide groove 20 is slidably connected to a mounting shell 13 , the interior of the mounting shell 13 is slidably connected to a detection head 14 , and the mounting shell 13 is convenient for mounting the detection head 14 .

[0034] As attached Figure 6 As shown, two limiting holes 15 are provided at the rear end of the detection head 14 , and the limiting holes 15 facilitate the insertion of the limiting rod 16 .

[0035] As attached Figure 7 As shown, the limiting hole 15 is internally slidably connected to a limiting rod 16, one side of the mounting shell 13 is fixedly connected to two second springs 17, the other ends of the two second springs 17 are fixedly connected to one end of the limiting rod 16, the other end of the limiting rod 16 is provided with two thread grooves 18, the external threads of the thread grooves 18 are connected to a limiting nut 19, the rebound force of the second spring 17 facilitates the rebound of the limiting rod 16, so that the limiting rod 16 is inserted into the inside of the limiting hole 15.

[0036] As attached Figure 5As shown, one end of the clamping rod 10 is fixedly connected to a pulling block 21 to facilitate pulling the clamping rod 10 .

[0037] As attached Figure 1 As shown, the other end of the bidirectional screw rod 2 is fixedly connected with a handle 22 to facilitate the rotation of the bidirectional screw rod 2.

[0038] Working principle: When clamping and fixing the shaft part before testing, first turn the handle 22 according to the length of the shaft part, so that the handle 22 drives the bidirectional screw rod 2 to rotate. When the bidirectional screw rod 2 rotates, it drives the movable plates 3 on both sides to approach each other, so that the movable plates 3 are close to the shaft part, so that it is convenient to flexibly adjust the length required for clamping according to the length of the shaft part, and then pull the pull block 21, so that the pull block 21 drives the other end of the clamping rod 10 to slide into the inside of the fixed shell 9, thereby squeezing the first spring 11, so that the clamping rod 10 is released from the corresponding hole groove 8, and then the adjusting column 5 is released from the limit, and then the adjusting column 5 is slid, so that according to the position that needs to be clamped in the shaft part, the length of the other end of the adjusting column 5 extending inside the fixed tube 4 can be flexibly adjusted. After adjustment, release the pull block 21. Under the action of the first spring 11, it is convenient to push the clamping rod 10 to engage with the corresponding hole groove 8, so that the position of the adjusting column 5 is fixed. The threaded column 6 is then rotated again, so that the threaded column 6 is threaded down at the other end of the adjusting column 5, driving the clamping block 7 to descend, thereby facilitating clamping according to the size of the clamped shaft part, thereby improving the adjustability during clamping. When the detection head 14 needs to be replaced after a long period of use, the limiting nut 19 is first twisted to remove the limiting nut 19, and then the limiting rod 16 is pulled. When the limiting rod 16 is pulled to the outside of the limiting hole 15, the second spring 17 is pulled, thereby facilitating the detection head 14 to release the limiting fixation, and then the detection head 14 is taken out, which is convenient for maintenance of the detection head 14. When replacing, the detection head 14 is inserted into the interior of the mounting shell 13, and the pulled limiting rod 16 is released. Under the rebound action of the second spring 17, it is convenient to insert the limiting rod 16 into the interior of the two limiting holes 15, and then the limiting nut 19 is screwed to the outside of the threaded groove 18, which is convenient for fixing the replaced detection head 14, thereby completing the replacement of the detection head 14.
