Retraction Mechanism of Metal Circular Saw Blade Grinding Machine

Abstract

Disclosed is a cutter withdrawal mechanism of a metal circular saw blade grinding machine. The grinding machine comprises a gear grinding cutter driving device which is arranged on a machine frame. The gear grinding cutter driving device comprises a bearing plate, a supporting base which is arranged on the bearing plate in a sliding mode, a cutter driving motor arranged on the supporting base and a cutter fixing frame. A cutter revolving shaft which is capable of revolving in the radial direction is arranged on the cutter fixing frame, a cutter is fixedly connected with the cutter revolving shaft in a sleeved mode, and the bearing plate is arranged on the machine frame in a sliding mode. The grinding machine further comprises an automatic driving device which is connected with the supporting base in a transmission mode and is capable of resetting the cutter by pulling the cutter. After grinding of one metal circular saw blade is finished, the cutter is driven by the automatic driving device to slide along the direction away from the metal circular saw blade, and then the cutter is reset. The speed of the action is quick, so that the cutter withdrawal speed is greatly accelerated, and at least the cutter withdrawal movement can be finished without complex manual operation. Due to the fact that the grinding machine has the advantages, the grinding machine can be applied in the metal circular saw blade grinding machine and the cutter withdrawal mechanism of the metal circular saw blade grinding machine.

Description

technical field [0001] The invention relates to a sawtooth processing machine for metal circular saw blades, in particular to a tool retracting mechanism for grinding and processing new saw teeth of metal circular saw blades or finishing old saw teeth by means of grinding. Background technique [0002] Metal circular saw blades are utensils widely used for cutting metal rods, pipes or plates. Generally, the metal circular saw blade is circular, and the outer periphery is provided with sawtooth. When the metal circular saw blade is installed on the rotating output shaft of a rotating machine such as a motor, the rotating metal circular saw blade can cut the metal material. In the process of cutting metal materials, the most easily damaged parts are the serrations on the outer periphery of the saw blade, and one of the key points that determines the sawing effect, speed and other results is also the serrations on the outer periphery of the saw blade. [0003] When the metal c...

Problems solved by technology

[0008] In the above solution, it can be found that after the cutter 413 finishes processing a piece of metal circular saw blade, the positioning adjustment lever 354 must be manually rotated to drag the support seat 352 back, so that the cutter 413 leaves the metal circular saw blade, commonly known as retracting and resetting. Such a retracting process not only takes a long time, but also requires a long time for the cutter 413 to approach the metal circular saw blade again when entering the next step.
