Workpiece holding mechanism

Abstract

The invention discloses a workpiece holding mechanism, which comprises a support, a first clamping jaw, a second clamping jaw and an air cylinder, wherein the support has an accommodating inner cavity; the lower end faces of the first clamping jaw and the second clamping jaw extend to the accommodating inner cavity of the support from the lower end face of the support; the parts in the accommodating inner cavity of the first and second clamping jaws are regulating parts, and the left parts of the first and the second clamping jaws are holding parts; a pressure spring is arranged between the regulating parts of the first and second clamping jaws; the holding parts of the first and second clamping jaws move close to each other under the action of the pressure spring; the outside side face of the regulating part of the first clamping jaw has a first inclined face, and the outside side face of the regulating part of the second clamping jaw has a second inclined face; the piston rod of the air cylinder extends into the accommodating inner cavity; the tail end of the piston rod of the air cylinder is connected with a lower pressure piece which has a first pressure head and a second pressure head; and the first pressure head is opposite to the first inclined face and the second pressure head is opposite to the second inclined face. In the invention, a workpiece is held by an air cylinder and clamping jaw cooperation mechanism, the structure of the mechanism is simple, and the cost of the mechanism is relatively low.

Description

technical field [0001] The invention relates to a workpiece clamping mechanism. Background technique [0002] In various numerical control devices, a manipulator is usually used for clamping workpieces, but the circuit structure of the manipulator is complex and prone to failure, and the cost is relatively high. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing workpiece clamping mechanism, the present invention provides a workpiece clamping mechanism with simple structure and low cost. [0004] The technical solution of the present invention to solve the technical problem is: a workpiece clamping mechanism, including a bracket, and the bracket has an accommodating inner cavity; [0005] It also includes a first jaw and a second jaw, the first jaw and the second jaw protrude into the accommodating cavity of the bracket from the lower end surface of the bracket, and the bracket passes through There are a first rotatin...
