Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1: referring to fig. 1-3, the present invention provides a technical solution: a stamping device for a cover plate of precision-working equipment comprises a working platform 1, wherein the working platform 1 is supported by four supporting legs 2, a clip-shaped limiting part 3 is fixed at the center of the top surface of the working platform 1, a vertical groove is formed in the clip-shaped limiting part 3 in a penetrating manner and a lower die part 4 capable of sliding seamlessly is sleeved on the clip-shaped limiting part, a plurality of first limiting columns 5 are fixed on the bottom surface of the lower die part 4, sliding grooves 6 which are in one-to-one correspondence with the first limiting columns 5 and are matched with the first limiting columns 5 in size are arranged on the working platform 1, the first limiting columns 5 are all penetrated through the corresponding sliding grooves 6, blocking parts 7 are arranged at the bottom ends of the first limiting columns 5, springs 8 positioned between the working platform 1 and the lower die part 4 are sleeved on each first limiting column 5, four second limiting columns 9 positioned outside the clip-shaped limiting part 3 are fixed on the working platform 1, and four corners of a lifting platform 10 are slidably connected on the second limiting columns 9, the lifting platform 10 is provided with a driving device 11, the bottom of the lifting platform 10 is provided with a stamping device 12 positioned right above the lower die piece 4, and the stamping device 12 can slide in the clip-shaped limiting piece 3 in a seamless manner when descending.
