Automatic double-sided chamfering device

Abstract

The invention discloses an automatic double-sided chamfering device which comprises a box body. A motor and a pushing part are further installed on one side of the box body, transmission rollers and areversing mechanism are installed in the box body, the transmission rollers are matched with the motor, a bearing seat is installed on the transmission rollers in a sliding mode, the bearing seat ismatched with a discharging groove and the pushing part, and the pushing part is further fixedly connected with the reversing mechanism. The reversing mechanism is matched with the bearing seat througha spring, and the reversing mechanism comprises a rough chamfering part, a fine chamfering part and a reversing motor. NdFeB blanks to be chamfered are driven by the transmission rollers to rotate together and are matched with a rough grinding head and a fine grinding head to be subjected to double-sided chamfering, so that the chamfering efficiency is improved. The rough chamfering part, the fine chamfering part and the reversing motor form the reversing mechanism, so that the rough chamfering process and the fine chamfering process can be completed simultaneously in one machining process. The feeding process, the rough chamfering process, the fine chamfering process, the discharging process and the stacking process of the device are all completed automatically, manual operation is not needed, efficiency is higher, and meanwhile safety is improved.

Description

technical field [0001] The invention relates to the field of NdFeB processing, in particular to an automatic double-sided chamfering device. Background technique [0002] NdFeB is a kind of permanent magnet material, which has the title of "Magnetic King". It is widely used in electronic products, such as hard disks, mobile phones, earphones and battery-powered tools. Sintering, machining, electroplating, magnetization and other processes. [0003] The existing NdFeB production can process various shapes of NdFeB raw materials according to the demand during machining, such as the most commonly used cylindrical shape, hexahedron shape and tile shape, etc., and then process the processed raw materials Grinding and chamfering, while the existing cylindrical raw materials need to be chamfered on both sides, and the chamfering needs to be rough chamfered first and then finely chamfered, so it is necessary to perform rough chamfering on one side first, and then pass Turn the pro...

[0003] The existing NdFeB production can process various shapes of NdFeB raw materials according to the demand during machining, such as the most commonly used cylindrical shape, hexahedron shape and tile shape, etc., and then process the processed raw materials Grinding and chamfering, while the existing cylindrical raw materials need to be chamfered on both sides, and the chamfering needs to be rough chamfered first and then finely chamfered, so it is necessary to perform rough chamfering on one side first, and then pass Turn the product over manually to perform rough chamfering on the other side. After the rough chamfering is completed, the product is manually taken out and put into another equipment to repeat the above chamfering process for fine chamfering, which leads to low processing efficiency and time-consuming manual operation. There are safety hazards in the laborious work, so now there is an urgent need for a device that can automatically complete the rough and fine chamfering of NdFeB
