Detailed Description

In order to make the technical solution of the present invention better understood, the technical solution of the embodiments of the present invention will be clearly and completely described below, 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 efforts shall belong to the protection scope of the present invention.

As shown in figures 1 to 3.

The utility model provides a positioning fixture for milling of compressor cylinder body, which comprises a fixture chassis 1, a connecting fixed groove 2, a T-shaped groove 3, a mounting plate 4, a T-shaped nut 5, a corner cylinder 6, a pressing plate 7, a positioning disc 8, a central positioning shaft 9, a positioning pin 10, a connecting rod 11, a connecting base rod body 111, a fixing plate 112, an expansion spring 113, a fixing auxiliary bulge 114, a connecting groove 12 and a positioning mounting disc 13, which can be seen from figures 1,2 and 3, when different compressor cylinder bodies are changed, the proper positioning disc 8 needs to be changed, the positioning disc 8 is changed only by drawing the expansion spring upwards through a large force, then the proper positioning disc 8 is installed, at the moment, the positioning disc 8 is mutually connected with the connecting groove 12 of the positioning mounting disc 13 through the connecting rod 11 below the positioning disc 8, after the connection is completed, the fixing auxiliary bulge 114 tightly contacts the inside of the connecting groove 12 through the tension of the expansion spring 113, thereby make connecting rod 11 fix inside spread groove 12, and because connecting rod 11 and spread groove 12 all are ' ten ' word structure, so the lathe adds man-hour to the compressor cylinder body, the compressor cylinder body can not appear the condition of rocking about also (fixed supplementary protruding piece 114 can restrict location mounting disc 13 through self cooperation spread groove 12 structure and appear rocking), and spread groove 12 still can accelerate and restrict the installation of positioning disc 8, restriction positioning disc 8 installation mistake's condition takes place.
