Problems solved by technology

The traditional processing technology of the screw is complicated, and the precision is difficult to grasp, especially the bottom part of the screw. The screw processed by the traditional process is easy to cause the deformation of the screw, increase the internal stress of the screw, reduce the quality and service life of the screw, and the processed The accuracy of the screw profile is not high, and the smoothness is difficult to meet the needs of actual production and processing. In addition, most of them are manually operated, with low automation, long processing time, high labor intensity, and low production efficiency. It is difficult to form mass production; It is difficult to grasp the degree of wear of the abrasive tool, which easily affects the grinding quality and the mechanical utilization rate is low

Abstract

The invention discloses a forward and reverse tooth grinding device. The device comprises a numerical control index head, a grinding mechanism and a grinding motor. The numerical control index head is connected with the grinding mechanism through a turning-connection fixing plate. The turning-connection fixing plate is provided with a motor fixing plate. The grinding motor is installed on the motor fixing plate. The grinding motor is in transmission connection with the grinding mechanism. The invention further discloses a full-automatic numerical control screw tooth grinding machine. The full-automatic numerical control screw tooth grinding machine comprises a lathe body, the tooth grinding device and a chuck, wherein the lathe body is provided with a middle tray and a guide rail. The tooth grinding device is the forward and reverse tooth grinding device. The tooth grinding device is arranged at one end of the middle tray, and the other end of the middle tray is further provided with a follow-rest preventing workpieces from vibrating. The tooth grinding device and the tooth grinding machine can easily achieve precise angle adjustment, forward and reverse grinding is conducted, speed regulation is convenient, the device and the machine are suitable for machining of various screw tooth types, and machining precision is greatly improved. The screw tooth grinding machine can achieve automatic compensation according to the abrasion degree of a grinding tool, the machine utilization rate is greatly increased, cyclic work of machines is guaranteed, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical production and processing equipment, in particular to a digitally controlled positive and negative tooth grinding device and a fully automatic numerically controlled screw tooth grinding machine which can automatically adjust the spiral angle of grinding. Background technique [0002] Screw (English: screw), a cylinder with a spiral groove cut on the outer surface or a cone cut with a spiral groove on the conical surface, is a rod-shaped mechanical part that uses its own thread to transmit motion or power. As far as the injection molding machine is concerned, the screw is an important part of the injection molding machine. Its function is to convey, compact, melt, stir and apply pressure to the plastic, all of which are completed by the rotation of the screw in the barrel. The traditional processing technology of the screw is complicated, and the precision is difficult to grasp, especially the ...
