Postwelding grinding tool for machine needle

Abstract

The invention discloses a postwelding grinding tool for a machine needle. The postwelding grinding tool comprises an operation table. Two parallel guide rails are arranged on the operation table. A sliding block is cooperatively arranged between the guide rails. The sliding block is cooperatively provided with a sliding block drive mechanism driving the sliding block to walk back and forth along the guide rails. A rotating air cylinder is arranged at the upper end of the sliding block. The output end of the rotating air cylinder is fixedly connected with a machine head. A workpiece driving mechanism driving a workpiece to rotate is arranged in the machine head. A clamping head used for installing the workpiece is arranged at the middle portion of the machine head. A grinding wheel is rotationally arranged on the operation table. The axial direction of a driving shaft of the grinding wheel is consistent with that of the guide rails. By means of the postwelding grinding tool for the machine needle, the structure that the rotating air cylinder is fixedly connected to the clamping head used for installing the workpiece is adopted, the contact time and the jacking pressure between the workpiece and the wheel face of the grinding wheel are controlled, and the grinding amount is accurately controlled while grinding is ensured.

Description

technical field [0001] The invention relates to the field of grinding machinery, in particular to a grinding tool after bur welding. Background technique [0002] Dental burs need to be ground after welding the tool holder and the tool head. The current method is manual grinding. The above method is not only inefficient, but also the grinding accuracy is not accurate enough, which affects product quality. When semi-automatic grinding equipment is used for grinding, the workpiece frame that holds the workpiece needs to move back and forth during grinding. At present, the operator manually pushes it, which is not conducive to control. The improved technical solution adopts two sets of sliding mechanisms to control the back and forth movement of the knife feeding and grinding respectively, but the above-mentioned structure is complex, the grinding amount cannot be accurately controlled, and the vibration generated by grinding will affect the service life of the grinding tool. ...
