Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Example

As shown in Figures 1-4, the fixture for five-axis machining of special-shaped parts includes a base 1. The upper surface of the base 1 is provided with a stabilizing component 3 and a clamping adjustment component 2. The stabilizing component 3 includes a housing 301 and a push rod 302. The housing The bottom of 301 is fixedly connected to the base 1, and a push rod 302 passes through the housing 301. The clamping adjustment assembly 2 includes a connecting seat 201 and a slide plate 202. The connecting seat 201 is fixedly connected to the base 1, and the upper surface of the connecting seat 201 is fixedly connected to the sliding plate 202. A mounting block 203 is fixedly installed inside the sliding plate 202 , and a bolt 204 is installed in the mounting block 203 , and one end of the bolt 204 is pressed against the pulley 205 , and the pulley 205 is slidably installed inside the sliding plate 202 .
