High-precision bearing producing and machining equipment of industrial robot

Abstract

The invention belongs to the technical field of machining, and particularly relates to high-precision bearing producing and machining equipment of an industrial robot, the high-precision bearing producing and machining equipment comprises a base, an electric telescopic rod and a cutting tool, the electric telescopic rod is arranged on one side of the inner surface of the base, the cutting tool is arranged at one end of the electric telescopic rod, and a rotating assembly is arranged at the bottom end of the inner surface of the base; through mutual cooperation of the rotating assembly and the fixing assembly, the output end of an air pump pushes a connecting rod and a fixing block downwards, and when a limiting groove and a limiting column are matched and abut against each other, an output shaft of the air pump continuously pushes the fixing block downwards, so that the two ends of a supporting plate rotate, and the bottom end of the supporting plate pushes a pushing block towards one side; the pushing block pulls the movable rod to move along the movable groove and stretches the spring till the spring is attached to the inner wall of the bearing ring, so that the bearing rings of different specifications can be clamped and fixed, and meanwhile the motor can be used for driving the limiting column to drive the whole rotating assembly to rotate along with the rotating disc.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to high-precision bearing production and processing equipment for industrial robots. Background technique [0002] The bearing of an industrial robot is one of its key supporting parts. At present, the general process of bearing processing includes bearing steel raw materials, turning into inner sleeves, outer sleeves, bead blanks, heat treatment, and grinding into finished materials (the grinding process includes internal grinding , cylindrical grinding, centerless grinding), and finally assemble the finished product. [0003] The production and processing of bearings need to go through many processes, especially for the cutting process of its outer ring, the requirements are very strict. When the outer ring of the bearing needs to be cut, it is usually fixed by the fixture, and then the It cuts. [0004] The clamps in the prior art are usually clamped on both sides...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a high-precision bearing production and processing equipment for industrial robots. Through the mutual cooperation of the rotating assembly and the fixed assembly, the output end of the air pump is used to push the connecting rod and the fixed block downward. When matching and conflicting, the output shaft of the air pump continues to push the fixed block downward, so both ends of the support plate rotate, and the bottom end of the support plate pushes the push block to one side, and the push block pulls the movable rod to move along the movable groove and stretch the spring , until it fits the inner wall of the bearing ring, so that the bearing rings of different specifications can be clamped and fixed. Automatic calibration to ensure cutting accuracy, and then turn on the motor, so that the output shaft of the motor drives the turntable and the bearing ring to rotate, and because the cross-section of the limit post is rectangular, the limit groove and the limit post match each other, so the limit post drives the rotation The assembly as a whole rotates with the turntable, so that the stability of the bearing ring can be further improved on the basis of clamping and fixing the bearing ring, which solves the problem that the clamps in the prior art usually clamp it on both sides of the bearing ring, and then The drive assembly is then used to drive the bearing ring to rotate and cut its outer ring. In order to ensure that the outer ring of the bearing ring is fully cut, the fixture and the bearing ring need to rotate relatively, which results in the rotation of the bearing ring. The sliding friction between the bearing ring and the fixture not only increases the loss of the bearing ring and the fixture, but also affects the cutting accuracy of the bearing ring, and due to the relative movement of the bearing ring and the fixture, the stability of the bearing ring during the cutting process is poor.
