[0002] Gears are one of the most common components in mechanical products and are very important for them. The gearbox is the protective component of the gear assembly. Its housing is generally divided into an upper housing and a lower housing. When processing the lower housing, the blank of the lower housing must first be subjected to preliminary processing operations such as marking. Therefore, a fixture is required to clamp the lower housing of the gearbox to prevent the gearbox housing from shaking during the initial processing.

[0003] The existing gear box body fixture generally uses screws and clamps to fix the gear box body on the workbench. When this fixture is used, when the staff needs to perform preliminary processing on different parts of the gear box body, they need to move back and forth, which is extremely inconvenient.

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments; based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] As attached Figure 1 and attached Figure 2 As shown, a tooling fixture for machining a gear box body comprises a housing 1, a bottom frame 18 is installed on the lower side of the housing 1, a support frame 4 is provided on the inner side of the bottom of the housing 1, a support platform 3 is rotatably installed at the center of the upper side of the support frame 4, a mounting ring 2 is rotatably installed inside the housing 1 and located on the upper side of the support frame 4, a latch 5 passes through one side wall of the housing 1, a plurality of groups of sockets 7 for inserting the matching latch 5 are equidistantly provided on the side wall of the mounting ring 2, a collecting box 17 is installed on the lower side of the housing 1, and clamping structures are respectively installed on the upper sides of the four side walls of the mounting ring 2;

[0027] The clamping structure comprises a support plate 12 , a threaded shaft 13 is installed through the support plate 12 in cooperation with a thread, and an arc-shaped clamping plate 14 is rotatably installed at the other end of the threaded shaft 13 .

[0028] Through the above structure, the gear box is placed on the upper side of the support platform 3, and an arc-shaped clamping plate 14 that is relatively fitted with the gear box is selected and installed on the end of the threaded shaft 13. The multiple groups of threaded shafts 13 are rotated to push the arc-shaped clamping plate 14 toward the gear box. The gear box is clamped and fixed by the arc-shaped clamping plates 14 on the four sides. When it is necessary to perform preliminary processing on other parts of the gear box, the pin 5 is pulled out from a group of sockets 7, and the mounting ring 2 is rotated. The gear box is driven to rotate by the clamping structure on the mounting ring 2. After adjusting the angle of the gear box, the pin 5 is inserted into the corresponding socket 7 to position the mounting ring 2. The specific structure is as follows:

[0029] Combined with Figure 2 and attached Figure 5 As shown, a support pile 15 is rotatably installed on the lower side of the support platform 3, and the lower end of the support pile 15 is fixedly connected to the center of the upper side of the support frame 4. A spring 6 is installed between the top of the latch 5 and the shell 1, and the spring 6 is sleeved on the outside of the latch 5.

[0030] Through the above structure, when the gear box rotates, the support platform 3 is driven to rotate at the same time on the top of the support pile 15 to prevent the support platform 3 from generating friction on the gear box. When the pin 5 is pulled out of the socket 7, the spring 6 is unfolded. When the pin 5 is inserted back into the socket 7, the rebound force of the spring 6 prevents the pin 5 from detaching from the socket 7.

[0031] Combined with Figure 1 and attached Figure 4 As shown, a threaded connection ring 16 is installed on the lower side of the support frame 4, and the collection box 17 is threadedly sleeved on the outer side of the threaded connection ring 16, and a through hole 19 is provided on one side of the base frame 18 for the collection box 17 to pass through.

[0032] Through the above structure, the collection box 17 is installed to the outside of the threaded connecting ring 16 through threads, and the debris generated inside the shell 1 can be collected in the collection box 17. The collection box 17 is easy to disassemble. The disassembled collection box 17 is taken out through the through hole 19 to clean the debris.

[0033] Embodiment 2

[0034] Based on Example 1, please refer to the attached Figure 1 and attached Figure 3 A support ring 8 is installed on the lower side of the mounting ring 2, and an annular limiting frame 9 is installed on the lower side of the support ring 8. A limiting annular groove 10 is provided on the upper side of the support frame 4 to cooperate with the annular limiting frame 9 for rotation, and multiple groups of balls 11 are rotatably embedded in the lower side of the annular limiting frame 9.

[0035] Through the above structure of the second embodiment, the cross section of the annular limit frame 9 is a "convex"-shaped structure and is limitedly rotated inside the limit annular groove 10. The movement resistance of the annular limit frame 9 inside the limit annular groove 10 is reduced by multiple groups of balls 11.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0038] The above describes the utility model and its implementation methods, which are not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and do not deviate from the purpose of the invention of the utility model, they can creatively design a structure and embodiment similar to the technical solution, which should belong to the protection scope of the utility model.
