Description

Technical Field

[0001] This utility model relates to the field of axle gear technology, specifically a split fixture structure for leak-proof machining of axle gear stop. Background Technology

[0002] The differential half-shaft gear plays a crucial role in automobiles. It not only transmits power but, more importantly, changes the direction of torque, enabling differential rotation. Its performance and condition directly affect the vehicle's driving safety and comfort. The position of the half-shaft gear's stop is particularly important; it improves system rigidity, reduces vibration and deformation during operation, prevents axial movement of the gear, and prevents poor gear meshing and breakage caused by misalignment. It also simplifies the assembly of the entire differential. Currently, some half-shaft gears are omitted during finishing processes due to various reasons, resulting in the stop not being machined. Inspectors only perform visual checks to address this issue, leading to defective products reaching customers, causing assembly problems and complaints. This inspection method is not reliable and is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this utility model is to provide a split fixture structure for leak-proof machining of the stop of a half-shaft gear, so as to solve the problems raised in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a split fixture structure for leak-proof machining of a half-shaft gear stop, comprising a base and a half-shaft gear body. A fixed inspection mechanism is provided inside the base, the fixed inspection mechanism including a boss. The boss is movably connected inside the base, and a first rack is fixedly connected to the outer wall of the boss. A second rack is fixedly connected to the inner wall of the half-shaft gear body, the first rack and the second rack meshing with each other. A fixed plate is movably connected to the top of the base, a support platform is fixed to the top of the fixed plate, a third rack is fixedly connected to the inner wall of the support platform, and a fourth rack is fixedly connected to the bottom of the half-shaft gear body, the third rack and the fourth rack meshing with each other.

[0005] As a preferred technical solution, the vertical center line of the boss coincides with the vertical center line of the base, and the boss is convex in shape.

[0006] As a preferred technical solution, the vertical center line of the fixing plate coincides with the vertical center line of the base, and the fixing plate is circular in shape.

[0007] As a preferred technical solution, the boss is provided with a replacement mechanism inside, and the replacement mechanism includes a first threaded hole.

[0008] As a preferred technical solution, both the interior of the boss and the interior of the base are provided with first threaded holes, and the number of first threaded holes is four.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1 and Figure 2 As shown, the present invention provides the following technical solution, including a base 1 and a half-shaft gear body 4. The base 1 is provided with a fixed inspection mechanism 2, and the boss 201 is provided with a replacement mechanism 3.

[0023] Specifically: When this fixture structure is needed, the matching boss and support platform 201 need to be replaced according to the different half-shaft gear models. The matching boss and support platform 201 are replaced according to the different half-shaft gear models through the set replacement mechanism 3. After replacement, the half-shaft gear body 4 can be fixed and inspected through the set fixing and inspection mechanism 2, thereby completing the work.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, a fixed inspection mechanism 2 is provided inside the base 1. The fixed inspection mechanism 2 includes a boss 201. The boss 201 is movably connected inside the base 1. A first rack 202 is fixedly connected to the outer wall of the boss 201. A second rack 203 is fixedly connected to the inner wall of the half-shaft gear body 4. The first rack 202 and the second rack 203 mesh with each other. A fixed plate 204 is movably connected to the top of the base 1. A support platform 205 is fixed to the top of the fixed plate 204. A third rack 206 is fixedly connected to the inner wall of the support platform 205. A fourth rack 207 is fixedly connected to the bottom of the half-shaft gear body 4. The third rack 206 and the fourth rack 207 mesh with each other. The vertical center line of the boss 201 coincides with the vertical center line of the base 1, and the shape of the boss 201 is "convex". The vertical center line of the fixed plate 204 coincides with the vertical center line of the base 1, and the shape of the fixed plate 204 is circular.

[0025] After replacement, the half-shaft gear body 4 can be fixed and inspected. The half-shaft gear body 4 is directly aligned and inserted, so that the second rack 203 on the half-shaft gear body 4 meshes with the first rack 202 on the boss 201, and the fourth rack 207 at the bottom of the half-shaft gear body 4 meshes with the third rack 206 in the support platform 205, so that the half-shaft gear body 4 is fixed and inspected. If the racks cannot mesh with each other, it proves that the half-shaft gear body 4 is unqualified, thus completing the fixing and inspection work.

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the boss 201 is provided with a replacement mechanism 3 inside. The replacement mechanism 3 includes a first threaded hole 301. The boss 201 and the base 1 are both provided with first threaded holes 301. There are four first threaded holes 301. The inner wall of the first threaded hole 301 is threaded with a first bolt 302. The shape and size of the first bolt 302 match the shape and size of the first threaded hole 301. The fixed plate 204 and the top of the base 1 are both provided with second threaded holes 303. There are four second threaded holes 303. The inner wall of the second threaded hole 303 is threaded with a second bolt 304. The shape and size of the second bolt 304 match the shape and size of the second threaded hole 303.

[0027] When this fixture structure is needed, the first step is to replace the corresponding boss and support platform 205 according to the different half-shaft gear models. First, the first bolt 302 is rotated out from the inner wall of the first threaded hole 301 to separate the boss 201 from the base 1. Then, the appropriate boss 201 is placed inside the base 1, and the first threaded hole 301 in the boss 201 is aligned with the first threaded hole 301 in the base 1. Next, the first bolt 302 is rotated and inserted into the inner wall of the first threaded hole 301 to fix the appropriate boss 201 inside the base 1. Then, the second bolt 304 is rotated out from the second threaded hole 303 to separate the support platform 205 from the base 1. The appropriate support platform 205 is then pressed tightly against the top of the base 1, and the second threaded hole 303 in the support platform 205 is aligned with the second threaded hole 303 on the top of the base 1. Finally, the second bolt 304 is rotated and inserted into the second threaded hole 303 to replace the appropriate support platform 205, thus completing the replacement work.

[0028] The working principle of this utility model is as follows: When this fixture structure is needed, firstly, the matching boss and support platform 205 need to be replaced according to the different half-shaft gear models. At this time, the first bolt 302 is rotated out from the inner wall of the first threaded hole 301, thereby separating the boss 201 from the base 1. Then, the suitable boss 201 is placed inside the base 1, and the first threaded hole 301 in the boss 201 is aligned with the first threaded hole 301 in the base 1. Then, the first bolt 302 is rotated and inserted into the inner wall of the first threaded hole 301 to fix the suitable boss 201 inside the base 1. Then, the second bolt 304 is rotated out from the second threaded hole 303 to separate the support platform 205 from the base 1. Finally, the suitable support platform 205 is tightened to the top of the base 1. Then, align the second threaded hole 303 in the support platform 205 with the second threaded hole 303 on the top of the base 1, and then rotate the second bolt 304 into the second threaded hole 303. Replace the support platform 205 with a suitable one to complete the replacement. After replacement, the half-shaft gear body 4 can be fixed and inspected. At this time, the half-shaft gear body 4 is directly aligned and inserted so that the second rack 203 on the half-shaft gear body 4 meshes with the first rack 202 on the boss 201, and the fourth rack 207 at the bottom of the half-shaft gear body 4 meshes with the third rack 206 in the support platform 205 to fix and inspect the half-shaft gear body 4. If the racks cannot mesh with each other, it proves that the half-shaft gear body 4 is unqualified, thus completing the fixing and inspection work.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
