[0002] The joint fork is an important component in the direction transmission system of the automotive steering system. Its main functions are to transmit torque, adjust the length and positional relationship of the drive shaft. The machining quality of the joint fork parts directly affects the installation accuracy, motion accuracy of the vehicle, as well as the working accuracy, service performance and service life of the chassis drive shaft.

[0003] In the field of machining, the machining accuracy of the locking holes of joint forks directly affects the assembly accuracy and service performance of mechanical components. Therefore, a suitable machining jig is required for machining the locking holes of joint forks. There are many types of traditional machining jigs for the locking holes of joint forks. For example, a machine tool jig for machining joint forks disclosed in Chinese Patent CN218744971U includes a bearing table and other structures. This joint fork jig improves the machining accuracy. However, the existing machining jigs for the locking holes of joint forks still have the defect of unstable clamping.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1-2 , the present utility model provides the following technical solution: a processing fixture for locking holes of a joint fork, including a connecting table 1, and a plurality of supporting feet 2 are provided on the lower surface of the connecting table 1.

[0023] Among them, a plurality of receiving shells 4 and connecting plates 3 are provided on the upper surface of the connecting table 1. A protective member 5 is provided on one side of the receiving shell 4. An electric push rod 6 with one end extending into the interior of the receiving shell 4 is provided on one side of the connecting plate 3. The output end of the electric push rod 6 is provided with a clamping rod 7 that penetrates through the receiving shell 4 and the protective member 5 and extends to the outside of the protective member 5.

[0024] In the above-mentioned embodiment, it should be understood that the clamping rod 7 is composed of a rod body and an anti-slip clamping head. An anti-slip clamping head is provided on one side of the rod body. The anti-slip clamping head is made of rubber material, has a small friction coefficient, can effectively prevent slipping, and improves the clamping stability.

[0025] By setting the electric push rod 6, the clamping rod 7 can be advanced for displacement, thereby realizing the clamping function.

[0026] In addition, a plurality of opposing clamping components for strengthening the clamping force are also provided on the upper surface of the connecting table 1. The opposing clamping components include a plurality of servo motors 8. The output shaft of the servo motor 8 is coaxially connected with a threaded rod 9. A threaded block 10 is threadedly connected to the outside of the threaded rod 9. A threaded groove is provided on the inner side wall of the threaded block 10, and the threaded groove is adapted to the thread strip on the outside of the threaded rod 9. Two limiting telescopic rods 11 are provided on one side of the threaded block 10, and the limiting telescopic rods 11 are connected to the servo motor 8. A plurality of connecting frames 12 are provided on the other side of the threaded block 10. A joint fork positioning block is provided on the side of the connecting frame 12 away from the threaded block 10.

[0027] It should be understood that the limiting telescopic rod 11 is composed of an outer rod and an inner rod. The inner rod is movably connected to the inside of the outer rod and has one end penetrating and extending to the outside of the outer rod. By setting the limiting telescopic rod 11, effective limiting treatment can be carried out on the threaded block 10 to avoid the phenomenon that the threaded block 10 rotates in place.

[0028] In the above-mentioned embodiment, by setting the opposing clamping components, opposing clamping treatment can be carried out, thereby improving the clamping stability.

[0029] It should also be noted that an adaptation groove is formed on one side of the joint fork positioning block. The shape of the adaptation groove is semi-circular. By providing the adaptation groove, one end of the joint fork can be adapted to enter the groove, thereby improving the stability during clamping.

[0030] The working principle of this embodiment is as follows:

[0031] First, place the joint fork to be processed between the joint fork positioning block 13 and the clamping rod 7. Then, start the servo motor 8 to rotate the threaded rod 9. By setting the limit telescopic rod 11 to limit the position of the threaded block 10, the threaded block 10 can be pushed to move along the axial direction of the threaded rod. The movement of the threaded block will drive the connecting frame 12 and the joint fork positioning block 13 to displace. During this process, start the electric push rod 6 to drive the clamping rod 7 to move until the clamping rod 7 and the joint fork positioning block 13 firmly clamp the joint fork to be processed, and then the processing can be carried out.

[0032] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
