Problems solved by technology

[0002] Nowadays, automobiles, motorcycles, ships, construction machinery, light industrial machinery and other industries have higher and higher requirements for machine tool processing efficiency and automation. On the rotating shaft, when the type of tooth blank needs to be replaced when the fixture needs to be replaced, the bolts must be removed, a new fixture must be installed, and then the fixture must be re-centered. This process of centering is very time-consuming. If the operator is not skilled, it will consume The time is doubled, seriously affecting the processing efficiency

Abstract

The invention discloses an automatic quick change device for workpiece fixtures for a gear shaving machine. The right end of a first rotating shaft (6) is tightly abutted to a first fixture (1) through a centre, the first fixture (1) penetrates into a positioning hole of a quick change bracket (9) for the fixtures, the quick change bracket (9) for the fixtures is rotatably connected onto a feeding mechanism (5), a first pull rod (10) penetrates into the first fixture (1), the right end of the first pull rod (10) extends into a central hole of the second fixture (2), the right end of the second fixture (2) is matched with a second rotating shaft (7) through a conical surface, a second pull rod (12) penetrates into the central hole of the second fixture (2), and the right end of the second pull rod (12) is connected with an openable and closable pull claw (13) in the second rotating shaft (7). By the aid of the automatic quick change device, centering time in fixture change is shortened, fixture change frequency is decreased, and the machining efficiency and the automation degree of a machine tool are improved. Besides, the automatic quick change device has the advantages of ingenious design, high reliability and the like.

Description

technical field [0001] The invention relates to a machine tool component, in particular to a workpiece fixture quick change device on a gear shaving machine. Background technique [0002] Nowadays, automobiles, motorcycles, ships, construction machinery, light industrial machinery and other industries have higher and higher requirements for machine tool processing efficiency and automation. On the rotating shaft, when the type of tooth blank needs to be replaced when the fixture needs to be replaced, the bolts must be removed, a new fixture must be installed, and then the fixture must be re-centered. This process of centering is very time-consuming. If the operator is not skilled, it will consume The time is doubled, seriously affecting the processing efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a quick-changing device for automatic workpiece fixtures for gear shaving machines that can effectively...
