[0012] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments thereof.

[0013] like Figure 2 A lathe for processing the center hole of an active gear includes a lathe 10, a tool 20 is provided on the top of the lathe, a fixed base 11 is provided at the bottom of the lathe 10, a rotating base 30 is provided on the outer side of the base 11, a fixture 31 is fixed on the rotating base 30, the base 11 is connected to the top base 121 through a two-dimensional adjustment mechanism 40, and a top pin 12 is fixed on the top base 121.

[0014] like Figure 3 The two-dimensional adjustment mechanism 40 includes an X-axis slider 41 and a Y-axis slider 43:

[0015] Two X-axis rails 111 are provided on the base 11, and two X-axis horizontal bars 411 are fixed at the bottom of the X-axis slider 41. The X-axis horizontal bars 411 are stuck in the X-axis rails 111, so that the X-axis slider 41 can slide on the base 11. An X-axis side plate 112 is fixed on the base 11, and an X-axis screw 42 is passed through the X-axis side plate 112. The stud section of the X-axis screw 42 is threadedly engaged with the X-axis side plate 112, and the optical column section of the X-axis screw 42 is rotatably connected to the X-axis slider 41. The optical column section of the X-axis screw 42 is fixed with a convex ring, which is stuck in the X-axis slider 41, so that when the X-axis screw 42 moves axially, the X-axis slider 41 also moves synchronously.

[0016] Two Y-axis rails 413 are provided on the X-axis slider 41, and two Y-axis horizontal bars 431 are fixed at the bottom of the X-axis slider 41. The Y-axis horizontal bars 431 are stuck in the Y-axis rails 413, so that the Y-axis slider 43 can slide on the X-axis slider 41. A Y-axis side plate 412 is fixed on the X-axis slider 41, and a Y-axis screw 44 is passed through the Y-axis side plate 412. The stud section of the Y-axis screw 44 is threadedly engaged with the Y-axis side plate 412, and the optical column section of the Y-axis screw 44 is rotatably connected to the Y-axis slider 43. The optical column section of the Y-axis screw 44 is fixed with a convex ring, which is stuck in the Y-axis slider 43, so that when the Y-axis screw 44 moves axially, the Y-axis slider 43 also moves synchronously.

[0017] The X-axis slider 41 , the X-axis screw 42 , the Y-axis slider 43 , and the Y-axis screw 44 are all metal parts.

[0018] Its working principle is:

[0019] When replacing the new ejector pin 12, fix the new ejector pin 12 on the ejector base 121. At this time, determine whether the position of the new ejector pin 12 is correct. If the answer is "no", adjust it as follows:

[0020] S1. Use manual or mechanical force to tighten the X-axis screw 42. The X-axis screw 42 moves spirally, driving the X-axis slider 41 to slide in the X-axis direction. The Y-axis slider 43 moves synchronously with the ejector base 121 and the ejector pin 12, so that the new ejector pin 12 is correctly positioned in the X-axis direction.

[0021] S2. Use manual or mechanical force to tighten the Y-axis screw 44. The Y-axis screw 44 moves spirally, driving the Y-axis slider 43 to slide in the Y-axis direction. The ejector base 121 and the ejector pin 12 move synchronously, so that the new ejector pin 12 is correctly positioned in the Y-axis direction.

[0022] In this way, the position of the new ejector pin 12 has no deviation, which brings convenience to subsequent workpiece processing.

[0023] For other contents, please refer to the prior art.

[0024] The above description is only the preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
