[0025] The utility model will be further described in connection with the drawings and examples:

[0026] In the example, as shown in Figure 2 、 Figure 3 The tool for gear shaft punching includes mounting seat 1, and includes:

[0027] Positioning hole 2 is uniformly distributed in the transverse and longitudinal direction of mounting seat 1, and is used for cooperating with the gear shaft;

[0028] Pressing block assembly 3 is arranged between adjacent positioning holes 2, and the pressing block assembly 3 is detachably connected with mounting seat 1;

[0029] Through hole 4 is arranged at the bottom of positioning hole 2;

[0030] Mounting plate 5 is arranged below through hole 4;

[0031] Jacking rod 6 is arranged on mounting plate 5 and is used for cooperating with through hole 4;

[0032] Power element 7 is used for driving mounting plate 5 to rise and fall.

[0033] The diameter of the positioning hole 2 is matched with the gear wheel shaft, a plurality of gear wheel shafts are placed in different positioning holes 2, and then the pressing block assembly 3 on both sides of the gear wheel shaft presses the gear wheel shaft and sends the mounting seat 1 to the machining center. When the punching is completed, the pressing block assembly 3 is removed, and finally the mounting plate 5 is driven to rise by the power element 7, so that the gear wheel shaft is pushed out by the ejector rod 6. The tooling can punch a plurality of gear wheel shafts at a time, and the working efficiency is high.

[0034] In the embodiment, as shown in the figure, Figure 4 The pressing block assembly 3 includes a pressing block 31 and a threaded rod 32. The threaded rod 32 penetrates the pressing block 31 and is threadedly connected with the mounting seat 1. An adjusting nut 33 is arranged on the threaded rod 32 and used for acting on the top surface of the pressing block 31. By rotating the adjusting nut 33 to act on the pressing block 31, the pressing block can press the gear wheel shaft. When the punching of the gear wheel shaft is completed, the threaded rod 32 is separated from the mounting seat 1, and the pressing block assembly 3 can be removed, which is convenient to disassemble and assemble.

[0035] In the embodiment, as shown in the figure, Figure 4 The side of the pressing block 31 matched with the gear wheel shaft is provided with a buffer layer 8. The buffer layer 8 is a rubber layer, which prevents the pressing block 31 from damaging the surface of the gear wheel shaft and affecting the product quality.

[0036] In the embodiment, as shown in the figure, Figure 2 , Figure 3 The mounting seat 1 is provided with a guide rod 9 used for cooperating with the mounting plate 5. The straightness of the lifting of the ejector rod 6 is ensured, and the gear wheel shaft is conveniently ejected from the positioning hole 2.

[0037] In the embodiment, as shown in the figure, Figure 2 , Figure 3 The circumferential surface of the positioning hole 2 is provided with a support table 10, and the surface of the support table 10 is provided with an anti-skid strip 11. The rotation of the gear wheel shaft during punching is prevented, and the punching accuracy is ensured.

[0038] In the embodiment, the power element 7 is a pneumatic cylinder. The pneumatic cylinder runs stably, is convenient to maintain, and has low cost.

[0039] In the embodiment, as shown in the figure, Figure 2 , Figure 3 The pressing block assembly 3 is arranged between four positioning holes 2 arranged in a rectangular shape. One set of pressing block assembly 3 can press one side of four gear wheel shafts, and the disassembly and assembly time of the pressing block assembly 3 is reduced.
