[0026] like Figure 1 As shown, the lock retainer spring tooling device of this utility model includes a base plate 1 and a tooling assembly disposed on the base plate 1. A clamping member 2 is provided on the base plate 1 for clamping the workpiece. The tooling assembly includes a positioning part and an installation part. The positioning part includes a positioning post 3 and a driving member 4 for driving the positioning post 3 to rise and fall. The installation part includes an insertion tube 5 and a driving member 6 for driving the insertion tube 5 to rise and fall. The retainer spring is sleeved on the positioning post 3. The driving member 4 drives the positioning post 3 to descend and press and fix it on the workpiece. The driving member 6 drives the insertion tube 5 to descend so that the insertion tube 5 abuts against the retainer spring and pushes the retainer spring down. The positioning post 3 is provided with a guide part. When the retainer spring descends relative to the positioning post 3, it can be opened by the guide part until the insertion tube 5 pushes the opened retainer spring into the retainer spring groove on the workpiece.

[0027] like Figure 5 As shown, the guide portion includes a tapered guide surface 7 formed on the positioning post 3. The diameter of the small end of the tapered guide surface 7 is smaller than the inner diameter of the retaining ring, and the diameter of the large end of the tapered guide surface 7 is larger than the outer diameter of the shaft on the workpiece. The positioning post 3 is fixed to the end of the driving component 4 by a positioning block 11, and the positioning post 3 is fixedly connected to the positioning block 11 by a connecting piece 12. The insertion tube 5 is a hollow round tube, and the insertion tube 5 is coaxially arranged with the positioning post 3. An opening is provided on the insertion tube 5 to avoid the connecting piece 12.

[0028] The workpiece has a mounting hole 15, which is coaxially arranged with the snap ring groove, such as... Figure 5 As shown, a guide post 16 is fixedly installed at the bottom of the positioning post 3. When the driving component 4 drives the positioning post 3 to descend, the guide post 16 is inserted into the mounting hole 15 of the workpiece to form a positioning. The guide post 16 is conical in shape, larger at the top and smaller at the bottom.

[0029] A support 8 is fixedly mounted on the base plate 1, and the tooling assembly is mounted on the support 8. The positioning part also includes a positioning plate 9, which is fixedly mounted on the support 8, and a driving component 4 is fixedly mounted on the positioning plate 9. The mounting part also includes a mounting plate 10, which is fixedly mounted on the support 8, and a driving component 6 is fixedly mounted on the mounting plate 10.

[0030] like Figure 6 As shown, a guide post 13 is fixedly mounted on the positioning plate 9, and the insertion tube 5 is sleeved on the guide post 13 and moves back and forth along the guide post 13. The guide post 13 and the positioning plate 9 are integrally formed. The positioning plate 9 has two arc-shaped clearance grooves 14, which are coaxially arranged with the guide post 13. The insertion tube 5 passes through the clearance grooves 14, and the connection between the guide post 13 and the positioning plate 9 is located in the opening of the connecting piece 12.

[0031] The working principle of this utility model is as follows:

[0032] like Figure 2 As shown, this is the original state of the tooling assembly. The worker places the retaining ring on the positioning post 3; as... Figure 3 As shown, the driving component 4 drives the positioning column 3 to descend and press against the workpiece, and the guide column 16 is inserted into the mounting hole 15 of the workpiece to form a positioning; as shown Figure 4 As shown, the second driving component 6 drives the insertion tube 5 to descend, which in turn spreads the snap ring along the positioning post 3 and pushes it into the snap ring groove to complete the installation.
