Description

Technical Field

[0001] This utility model relates to the field of flange inspection tools, and in particular to a flange hole position inspection tool. Background Technology

[0002] The rear axle flange, or simply flange, is a connecting component located between the wheel and the axle. Its main functions are to transmit torque and support the wheel. Flanges are typically made of high-strength materials to ensure they can withstand the enormous forces generated during truck operation.

[0003] As an important connecting component, the accuracy of the hole positions of flanges directly affects the sealing performance, stability, and operating efficiency of equipment. Therefore, after flange production, it is necessary to use testing equipment to check the hole positions. For example, Chinese utility model patent with patent publication number CN216482720U discloses a flange hole spacing positioning fixture. This fixture uses a sleeve shaft with the same number of holes as the flange. During testing, the flange is fitted onto the fixture accordingly. Based on the fixed position and shaft diameter of the large and small sleeve shafts on the fixture, it can be determined whether the hole spacing of the flange and the symmetry between the large and small holes on the flange meet the requirements. It is easy to operate and has a simple structure.

[0004] However, in actual operation, the aforementioned flange hole spacing positioning gauge can only inspect one type of flange because both the large and small sleeve shafts are fixed on the base, resulting in poor applicability to various inspection scenarios. Utility Model Content

[0023] In an exemplary implementation, such as Figures 1-4As shown, this embodiment provides a flange hole position gauge, including a ring body 100, rotating rods 200, a fixed shaft 300, and a movable shaft 400. Several rotating rods 200 are arranged in a ring above the ring body 100, and each rotating rod 200 has its rotation center around the axis of the ring body 100. The fixed shaft 300 is detachably mounted at the center of the ring body 100 and is used to position the center point of the flange. The number of movable shafts 400 is the same as the number of rotating rods 200. Several movable shafts 400 are slidably mounted on the top of several rotating rods 200, and the movable shafts 400 are used to correspond to the hole positions of the flange.

[0024] In this embodiment, the ring 100 is placed in the relevant working area. A gauge that can adapt to different hole positions is constructed by using a rotating rod 200 that can rotate on the top of the ring 100 and a moving shaft 400 that can move horizontally on the rotating rod 200. During operation, the rotating rod 200 is rotated, and the rotating rod 200 rotates around the axis of the ring 100, causing the moving shaft 400 to move horizontally on the top of the rotating rod 200. After the rotating rod 200 and the moving shaft 400 reach the inspection standard, the inspection can begin. In summary, this gauge achieves the purpose of adapting to flanges with various hole positions.

[0025] In one embodiment, please refer to Figures 1-2 A mounting bracket 110 is coaxially fixed inside the ring body 100. The ends of several rotating rods 200 are slidably connected to the outside of the mounting bracket 110. The side of the rotating rods 200 away from the bottom of the mounting bracket 110 is slidably connected to the top of the ring body 100. The fixed shaft 300 is threaded onto the top of the mounting bracket 110.

[0026] In this embodiment, the mounting bracket 110 is located at the center of the ring 100, and a first sliding groove 111 is provided on the outer side of the mounting bracket 110. The first sliding groove 111 is used to install the near end of the rotating rod 200. At the same time, the bottom of the rotating rod 200 is slidably connected to the top of the ring 100. When the rotating rod 200 rotates, the rotating rod 200 can rotate along the center of the ring 100.

[0027] In one embodiment, please refer to Figures 1-2 The rotating rod 200 includes a limiting slider 210 fixedly disposed at the bottom of one end away from the mounting bracket 110 and a fastening pin 220 threaded onto the limiting slider 210. One side of the limiting slider 210 is slidably connected to the outer side of the ring 100, and the tail end of the fastening pin 220 abuts against the outer side of the ring 100. The rotating rod 200 is provided with a strip groove 230 for mounting the moving shaft 400.

[0028] In this embodiment, a second sliding groove 120 is provided on the outer side of the ring body 100. One side of the limiting slider 210 is slidably disposed in the second sliding groove 120. When the fastening pin 220 is rotated, the tail end of the fastening pin 220 abuts against the inner wall of the second sliding groove 120. The fastening pin 220 is subjected to a reaction force, which causes the limiting slider 210 to be pressed into the second sliding groove 120, thereby fixing the position of the limiting slider 210.

[0029] Further, please refer to Figure 1 An observation hole 240 is provided at the connection between the rotating rod 200 and the limiting slider 210. An indicator plate 241 is provided inside the observation hole 240. The outer edge of the ring body 100 is provided with a first scale 250 that matches the indicator plate 241.

[0030] In this embodiment, the indicator plate 241, in conjunction with the first scale 250, can clearly indicate the angle of rotation of the rotating rod 200.

[0031] In one embodiment, please refer to Figure 1 Each movable shaft 400 includes a reciprocating component 410 disposed in the strip groove 230 and a knob 420 fixedly disposed at one end of the reciprocating component 410. The bottom end of the movable shaft 400 is threadedly connected to the top of the reciprocating component 410.

[0032] In this embodiment, the moving shaft 400 moves within the strip groove 230 of the rotating rod 200 via the reciprocating member 410.

[0033] Further, please refer to Figures 1-4 The reciprocating component 410 includes a screw 411 rotatably disposed in the strip groove 230 and a screw sleeve 412 threadedly sleeved on the outside of the screw 411. The top of the screw sleeve 412 is fixedly connected to a connecting block 430 extending to the outside of the strip groove 230 and slidably connected to the top of the rotating rod 200. The top of the connecting block 430 is threadedly connected to the bottom end of the moving shaft 400.

[0034] In this embodiment, rotating the knob 420 drives the screw 411 to rotate, which allows the screw sleeve 412 to move on it. The movement of the screw sleeve 412 can drive the moving shaft 400 to move through the connecting block 430, thus realizing the horizontal movement of the moving shaft 400 on the rotating rod 200.

[0035] Furthermore, both the fixed shaft 300 and the moving shaft 400 are detachable, such as threaded connections, to accommodate flanges with different bore diameters.

[0036] Please refer to Figure 1 and Figure 3 The top of the rotating rod 200 is provided with a second scale 440, and the outside of the connecting block 430 is provided with an indicator strip 431 that is adapted to the second scale 440. The indicator strip 431, in conjunction with the second scale 440, can clearly show the distance the rotating shaft 400 has moved, and can quickly determine the position of the rotating shaft 400.

[0037] In one embodiment, please refer to Figure 1 and Figure 2 The bottom of the ring body 100 is provided with a number of support blocks 500 distributed in a ring and fixedly installed. The bottom of each of the support blocks 500 is provided with a magnetic block 510 and a fixing plate 520, and the fixing plate 520 is provided with a fixing nail 530.

[0038] In this embodiment, the magnetic block 510 can adsorb part of the workbench, making it easy to operate. When the workbench material is not suitable for adsorption, it can be fixed by the fixing nails 530 on the fixing plate 520.

[0039] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail as follows: In use, the rotating rod 200 is rotated, and one end of the rotating rod 200 slides inward in the first sliding groove 111 of the mounting bracket 110. The bottom of the rotating rod 200 slides in a circular trajectory on the top of the ring body 100. At this time, the rotation angle and fixed position of the rotating rod 200 can be determined by the indicator plate 241 in the observation hole 240 in conjunction with the first scale 250. After that, rotating the knob 420 drives the screw 411 to rotate, which allows the screw sleeve 412 to move on it. The movement of the screw sleeve 412 can drive the moving shaft 400 to move through the connecting block 430. In this way, the moving shaft 400 moves horizontally on the rotating rod 200. At the same time, the indicator bar 431 in conjunction with the second scale 440 can clearly show the distance moved by the moving shaft 400, and the position of the moving shaft 400 can be quickly determined. After the positions of the rotating rod 200 and the moving shaft 400 reach the detection standard, the detection can begin.

[0040] In summary, this utility model solves the technical problem of poor inspection applicability caused by the fixed structure of the inspection fixture in the prior art by adopting a combination of a horizontally rotatable rotating rod 200 and a horizontally movable moving shaft 400. This achieves the purpose of adapting to flanges with various hole sizes and positions, and increases the technical effect of increasing the applicability of inspection scenarios.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
