The working principle of the grinding machine gear

At present, with the needs of industry and engineering, grinding machine gear has been used in many occasions, abrasive belt grinding machine has the advantages of high efficiency, flexibility and high precision. However, due to the complex structure, difficult manufacturing process, and heavy weight, it has brought certain difficulties to manufacturing and use, so let's understand the working principle of the grinder gear!

The purpose of the grinder gear is to provide an electric abrasive belt grinder with simplified structure, simple process, low cost and light weight. In addition to the existing electric grinder handle switch, motor, transmission wheel, gear, roller, grinding belt, the technical solution of the utility model, in particular, the utility model fixes the fork-shaped support plate on the shell beam, and the support plate is bent, The bending is fixed on the support plate by a pin,

The gear mechanism of the grinder has a screw, the screw is movably fixed on the swing rod, the rear end of the screw is fastened to the fork of the support plate, the swing rod is movably fixed on the housing through a pin, and one end of the swing rod is fixed on the stopper. The other end is fixed on the screw, and the stopper fastens the edge of the abrasive belt.

The working principle of the grinder gear is: hold the handle, press the switch, the motor starts, the motor transmits the power to the abrasive belt roller through a pair of transmission wheels and a pair of gears, and the abrasive belt roller drives the abrasive belt again. The double abrasive belt drive roller is installed on the support plate, and the movable turn rotates around the pin shaft and acts against the shell. Pull the roller to the right to easily remove or install the abrasive belt, move it again and bend it. Under the action of the spring, the support plate pushes the roller to the right end and tensions the abrasive belt. The abrasive belt driving roller mounted on the support plate can swing around the support table along the center line of the abrasive belt, and the abrasive belt can be prevented from slipping off due to uneven force received during operation and poor self-adhesion accuracy.

The grinder gear can select the position of the belt, and the stop and lever swing around the pin. The spring is to prevent loosening of the screws adjusted to the proper position. The function of the limit mechanism is to ensure that the abrasive belt is always in a good position when acting, so as not to cause slippage. The structure is that when the abrasive belt is pressed against the stop when it is working, due to the swing of the rod, the screw pressure plate support plate moving roller moves outward, and the abrasive belt immediately moves outward from the stop. When the abrasive belt is too far away from the stop, The support plate moves at a low speed under the action of the spring

The advantages of the new type of grinder gear are simplified structure, simple process, light weight, low cost, and easy to manufacture and use.
