[0040] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0041] like Figure 1-Figure 6 As shown, this embodiment includes a gear shaft anti-mistake positioning tool 100 and a gear shaft processing device, wherein the gear shaft processing device uses the gear shaft anti-mistake positioning tool 100.

[0042] The gear shaft anti-error positioning tool 100 includes a positioning block 20, which is provided with an anti-error groove 21, into which the milling groove end of the gear shaft 90 is inserted, and the milling groove end has an identification flat surface 91, and the inner side surface of the anti-error groove 21 is in contact with the identification flat surface 91; the positioning block 20 also has a positioning shaft 22 at one end facing the gear shaft 90, and the milling groove end of the gear shaft 90 has a positioning hole 92, and the positioning shaft 22 is used to be inserted into the positioning hole 92. By arranging the positioning shaft 22 on the positioning block 20, the positioning shaft 22 can penetrate the positioning hole 92 of the gear shaft 90, so that the gear shaft 90 can rotate relative to the positioning block 20. When the identification flat surface 91 of the gear shaft 90 rotates to correspond to the inner side surface of the anti-error groove 21, the gear shaft 90 can be inserted into the anti-error groove 21, and the inner side surface of the anti-error groove 21 can resist the identification flat surface 91 to realize the positioning of the gear shaft 90, which is convenient for subsequent processing of the gear shaft 90. The gear shaft anti-error positioning tool 100 can prevent the gear shaft 90 from being placed upside down, thereby improving the yield rate of the gear shaft 90.

[0043] After the gear shaft 90 has completed the previous process, the gear shaft 90 can be manually placed on the gear shaft anti-error positioning tool 100. The symmetrical grooves on both sides of the gear shaft 90 have a processing identification flat surface 91 on one side. The gear shaft anti-error positioning tool 100 uses the different groove spacing of the identification flat surface 91 to prevent errors. If the gear shaft 90 can be put in, it means the installation direction is correct, otherwise it is wrong.

[0044] In this example, the positioning block 20 further has a receiving groove 23, which is arranged opposite to the anti-error groove 21, and the width of the receiving groove 23 is greater than the width of the anti-error groove 21. Accordingly, the thickness of the gear shaft 90 inserted into the anti-error groove 21 is less than the thickness of the gear shaft 90 inserted into the receiving groove 23, thereby preventing the gear shaft 90 from being placed upside down.

[0045] An intermediate step 24 is formed between the accommodating groove 23 and the anti-error groove 21 , and the positioning shaft 22 is disposed on the intermediate step 24 .

[0047] The positioning block 20 further has a truncated platform 25 , which is disposed between the positioning shaft 22 and the middle step 24 .

[0048] The diameter of the truncated cone 25 may be smaller than the width of the middle step 24. The diameter of the truncated cone 25 also needs to be larger than the diameter of the positioning shaft 22.

[0049] The positioning block 20 is cylindrical in shape as a whole. An accommodating space 26 is defined inside the positioning block 20 . The accommodating groove 23 is communicated with the accommodating space 26 .

[0050] As an implementation manner, the axis of the positioning shaft 22 coincides with the axis of the positioning block 20 .

[0051] The gear shaft anti-misalignment positioning tool 100 further includes a support member 11 , and a positioning block 20 is sleeved on an end of the support member 11 .

[0052] This example may also include a gear shaft processing equipment, the gear shaft processing equipment includes the gear shaft anti-misalignment positioning tool 100 as above, the gear shaft processing equipment also includes a transmission device, the transmission device includes a material channel that can circulate, the material channel is provided with a pallet, and the gear shaft anti-misalignment positioning tool 100 is arranged on the pallet.

[0053] The gear shaft processing equipment further comprises a gear hobbing device, the claws of which are used to grab the gear shaft 90 , and the gear hobbing device is also used to process the gear shaft 90 .

[0054] With the rapid innovation of technology and the sharp rise in labor costs, automated production has become the most effective means of reducing costs that all industries have to give priority to, especially in the fiercely competitive automotive industry. As a second-tier supplier in the automotive industry, labor costs will account for a very large proportion of the total product cost. Therefore, in the next few years, how to effectively reduce labor costs while ensuring quality will become the key to the second-tier suppliers of the entire automotive industry. Gear shaft processing equipment can improve processing efficiency and ensure product quality. Gear shaft processing equipment can better meet the needs of energy conservation and emission reduction.

[0055] There are certain phase angle requirements between the milling groove end and the gear hobbing end of the gear shaft 90. The groove needs to be positioned during gear hobbing. Because the production line is an automatic production line, the placement direction of the gear shaft 90 has requirements. Gear shaft processing equipment transmission device, gear hobbing device. The gear hobbing device can also specifically include claws, gear hobbing tooling, gear hobbing tooling, etc. The transmission device can be an automatic circulation system, which can specifically include: a circulating material channel, a tray and a gear shaft anti-mistake positioning tooling 100. The gear shaft 90 is manually placed on the gear shaft anti-mistake positioning tooling 100, and the product is automatically transported to the place to be processed. The claw is connected to the gear hobbing machine, and the gear shaft 90 is automatically grabbed and placed on the gear shaft anti-mistake positioning tooling 100. The gear hobbing tool processes the gear shaft 90 according to the program. The use of gear shaft processing equipment can ensure the correctness of product installation, improve processing efficiency and reduce the defective rate.
