Industrial robot transmission shaft key groove machining fixture

Abstract

The invention discloses an industrial robot transmission shaft key groove machining fixture. The industrial robot transmission shaft key groove machining fixture comprises a fixture base plate, the upper right end of the fixture base plate is provided with a fixed tailstock, the middle portion of the upper end of the fixture base plate is provided with two oil cylinder base plates, the upper ends of the oil cylinder base plates are provided with top-tight cylinders, the rear portions of the upper ends of the oil cylinder base plates are provided with compressing cylinders, the left portion of the upper end of the fixture base plate is provided with a top-tight tailstock, four corners of the fixture base plate are provided with hanging rings, and the right sides of the oil cylinder base plates are provided with V-shaped supports. The industrial robot transmission shaft key groove machining fixture has the advantages that the structural design is reasonable, the production and manufacture cost are low, and the clamping and positioning accuracy are high; quick clamping of a transmission shaft of an industrial robot can be achieved, the auxiliary machining time of clamping is shortened, the production efficiency is improved, and the machining cost is lowered.

Description

technical field [0001] The invention relates to the technical field of production and processing of industrial robot parts, in particular to a processing fixture for key grooves of drive shafts of industrial robots. Background technique [0002] The processing fixture of industrial robot parts will affect the processing accuracy of parts, thus affecting the overall positioning accuracy and dynamic performance of the robot. [0003] At present, in the parts processing fixtures of robots, many fixtures are ordinary and complex, which is very inconvenient in the actual clamping project, especially in the batch processing process, the key dimensions are easy to exceed the tolerance, or the same batch of parts It is easy to exceed the required tolerance. For example, when machining the keyway of a robot transmission shaft, using ordinary fixtures such as a vise to hold the part can easily cause inaccurate axial and radial positioning, the surface of the part is easily clamped an...

[0002] The processing fixture of industrial robot parts will affect the processing accuracy of parts, thus affecting the overall positioning accuracy and dynamic performance of the robot

[0003] At present, in the parts processing fixtures of robots, many fixtures are ordinary and complex, which is very inconvenient in the actual clamping project, especially in the batch processing process, the key dimensions are easy to exceed the tolerance, or the same batch of parts Easy to exceed the required tolerance

For example, when machining the keyway of a robot transmission shaft, using ordinary fixtures such as a vise to hold the part can easily cause inaccurate axial and radial positioning, the surface of the part is easily clamped and damaged, and the clamping reference is not easy to locate, making tool setting and programming difficult. inconvenient

This not only increases the auxiliary time of clamping and wastes processing man-hours, but also the reference plane of each clamping is inaccurate, resulting in unqualified keyway symmetry
