Automatic grinding machine

Abstract

The invention discloses an automatic grinding machine and relates to the field of machines. The automatic grinding machine comprises supporting columns, a machine body, an operation platform and grinding mechanisms. The operation platform and the supporting columns are fixed to the upper portion of the machine body, and the grinding mechanisms are arranged on the supporting columns. The automatic grinding machine is characterized in that the number of the supporting columns and the grinding mechanisms is two, the two supporting columns and the two grinding mechanisms are symmetrically arranged on the two sides of the machine body, the operation platform is provided with a rotary disc and three-jaw chucks arranged on the rotary disc, the number of the three-jaw chucks is six, the six three-jaw chucks are symmetrically arranged with the axis of the rotary disc as the circle center, a driving rotary shaft is arranged at the bottom of the rotary disc and is in shaft connection with a motor, the motor is electrically connected with a controller, the motor is arranged below the rotary disc, the controller is arranged on one supporting column, and the diameter of the driving rotary shaft is 10-15 cm. The automatic grinding machine is high in workpiece grinding and clamping efficiency and saves the cost.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an automatic grinding machine. Background technique [0002] In the field of mechanical processing, metal cutting machine tools such as lathes, milling machines, automatic grinding machines, and boring machines are being widely used, and automatic grinding machines can not only process materials with high hardness, but also brittle materials. Therefore, automatic grinding machines are getting more and more in the field of mechanical processing. more and more widely used. When the existing general-purpose automatic grinding machine is working, the workpiece is clamped and fixed by special or general-purpose fixtures (such as chucks), and then the workpiece is processed. The size of the clamping force, if the fixture is clamped too tightly, it will damage the workpiece. If the fixture is too loose, it will cause the workpiece to shift during the processing and affect the processing progress...

Problems solved by technology

When the existing general-purpose automatic grinding machine is working, the workpiece is clamped and fixed by special or general-purpose fixtures (such as chucks), and then the workpiece is processed. The size of the clamping force, if the fixture is clamped too tightly, it will damage the workpiece. If the fixture is too loose, it will cause the workpiece to shift during the processing and affect the processing progress; A series of steps such as workpiece, clamping, processing, unscrewing, and disassembling the workpiece, so the clamping process takes a long time and the work efficiency is low. The application number is CN201320532310.9 which discloses an automatic grinding machine, including a support column, a machine body, an operating platform and Grinding mechanism, the operating platform is fixed on the body, and it is characterized in that: the operating platform is provided with a permanent magnetic chuck, and the permanent magnetic chuck includes a disc body and a magnetic table composed of a plurality of permanent magnets, and the permanent magnet is made of neodymium located in the inner layer. The iron-boron layer is compounded with the ferrite layer located on the outer layer. There is a transmission mechanism inside the disc body to control the rotation of the permanent magnet. The permanent magnet chuck is set on the operating platform of this kind of automatic grinding machine. The permanent magnet chuck is made of the inner layer of NdFeB The outer ferrite layer and the outer ferrite layer are combined, and the workpiece is directly adsorbed by the permanent magnetic chuck without disassembly, clamping and other steps, so the clamping process is short and the work efficiency is high; by changing the NdFeB layer and ferrite The thickness or area ratio of the body layer can be adjusted arbitrarily within the required range of magnetic field strength, but this kind of automatic grinding machine uses magnet adsorption to clamp the workpiece, the workpiece is not easy to clamp, and it is easy to generate displacement during the grinding process, which affects Machining accuracy, and using a single station for grinding, the processing efficiency is low
