New drive mode of straight channel type vibration machine and drive structure thereof

Abstract

The invention discloses a novel transmission mode of a straight groove vibration machine and a transmission structure thereof. In the method, a universal coupler is driven by a motor, and an eccentric wheel shaft and an eccentric block group in a bearing seat at the bottom of a groove body are driven by the universal coupler so as to lead the groove body to vibrate regularly. The structure comprises the groove body (1), the lower part of which is connected with the bearing seat (2); the bearing seat (2) is internally provided with the eccentric wheel shaft (7), and two ends of the eccentric wheel shaft (7) are respectively provided with a group of eccentric wheels (3); the eccentric wheel shaft (7) is connected with the universal coupler (4); and the other end of the universal coupler (4)is connected with an output shaft of the motor (5). The invention effectively eliminates the twist of the groove body caused by asynchronous vibration sources, and the common motor replaces the expensive vibration motor, thus reducing the requirement on the groove body stiffness, improving the stability of the vibration machine, and leading the grinding vibration to be stable. The invention has good grinding effect, saves the cost, and is convenient for maintenance.

Description

Technical field [0001] The invention relates to a transmission mode and a transmission structure for a straight slot type vibration machine, belonging to the technical field of vibration transmission. technical background [0002] In the field of abrasive grinding technology, straight trough vibrating machines generally adopt a vibration motor installed below the trough body, and the vibration motor is used to drive the trough body to vibrate to achieve grinding of the workpiece. Because the vibration motor is in a state of vibration during the working process, the vibration motor is extremely easy to be damaged, and the price of the vibration motor is expensive, which is 3 to 4 times that of the ordinary motor. For the straight-slot type vibrator with a longer tank, because the tank is too long, it is difficult for a single vibration motor to drive uniformly in the vibration plane. It is necessary to install two vibration motors. After using two vibration motors, it is not only ...

AI Technical Summary

Problems solved by technology

Because the vibration motor is in a vibrating state during the working process, the vibration motor is extremely easy to damage, and the vibration motor is expensive, which is 3 to 4 times that of ordinary motors.

For the straight trough vibrating machine with a long tank, because the tank is too long, it is difficult for a single vibration motor to drive evenly in the vibration plane, and two vibration motors need to be installed. After using two vibration motors, not only the cost It is greatly improved, and because the two vibration motors cannot be completely synchronized when they are working, the tank is subjected to a large torque, and the tank is distorted and vibrated, which cannot achieve the expected effect, and the rigidity of the tank is required very high. , which increases the cost to a certain extent

The incomplete synchronous vibration of the other two vibrating motors will lead to the inconsistency of the positions of the eccentric wheels, making the working condition of the vibrating machine unstable, causing the trajectory of the abrasive to be disordered, and the expected grinding effect cannot be achieved.

Therefore, the transmission mode of the existing straight trough vibrator still needs to be improved
