Automatic grinding equipment for medium-sized casting

Abstract

The invention provides automatic grinding equipment for a medium-sized casting. The automatic grinding equipment for the medium-sized casting comprises a drum-type chain conveying track, conveying motors, a plurality of sensors, a double-station rotary working table, a feeding and discharging assembly and an industrial robot, wherein the drum-type chain conveying track comprises a feeding end, a preparation station section and a discharging end; the conveying motors are used for providing power for the drum-type chain conveying track; the double-station rotary working table is installed on the left side of the preparation station section; a working station for fixing a casting blank is arranged on the working table; each conveying motor is provided with speed reducer with a fixed speed ratio and is used for providing power for the drum-type chain conveying track; the three conveying motors are installed at the feeding end, the preparation station section and the discharging end correspondingly; the feeding and discharging assembly is installed on the right side of the preparation station section, and comprises an air cylinder and a V-shaped block fixedly installed at the front end of the air cylinder; an electromagnet is installed in the V-shaped block; and a clamping device is installed at the flange end of a sixth shaft, and clamps a grinding tool for grinding the casting blank at the working station.

Description

Technical field [0001] The present invention relates to a medium-sized casting automatic grinding apparatus; for Mm within the cylindrical blank polished. Background technique [0002] Rough castings cleaning required for sub-surface grinding, to remove flash burr, conventional grinding is performed manually grinding is completed, the operator handheld grinding apparatus for processing, not only low efficiency, high cost, and high degree of risk, grinding dust produced the health of the operating personnel can also cause damage, due to the development of artificial intelligence, is currently little rough castings (small error range) are used for grinding robot, however, the large cast is mostly artificial polish; this is because the size of the error in casting range, and the error generation position also vary, polished by the polishing apparatus of a robot hand, according to a preset taking the absolute path trajectory, so inevitably collide wall thickness, the damage to the g...

AI Technical Summary

Problems solved by technology

[0002] Casting rough cleaning needs to grind the parting surface to remove flash and burrs. Traditional grinding is done manually, and the operator holds the grinding device for processing. Not only is the efficiency low, the cost is high, and the degree of danger is high. The dust generated by grinding It will also cause damage to the health of operators. Due to the development of artificial intelligence, at present, small casting blanks (with a small error range) are polished by robots, but most medium and large castings are still manually polished; this is because of the size error of medium castings. The range is large, and the position of the error is also different. The grinding device held by the robot is used for grinding, and it follows the absolute path according to the preset trajectory. In this way, collisions will inevitably occur at the wall thickness, which will damage the grinding device or The body of the blank, or there is a void in the thin wall

[0003] However, if the most advanced visual detection automatic grinding device is used, it is necessary to produce different three-dimensional graphic databases for each casting in real time, and a large amount of computing equipment is required. The equipment cost is extremely high and cannot be widely used; The overall color of most castings is consistent and dark, resulting in wrong 3D graphics after being read by the camera, resulting in problems during grinding, resulting in a high failure rate. The above problems make it difficult to realize the automatic grinding system for medium and large castings at low cost
