Knowledge of grinder

Nov. 09, 2019

We are a grinder supplier,our products are widely used in power generation, petroleum, papermaking, steel, chemical industry and metallurgy.Do you know what a stationary valves grinder machinery is?

The stationary valves grinder machinery is composed of a power part, a transmission part, a grinding head part and a bracket part, and the transmission part is composed of a transmission shaft, an input gear pair and an output gear pair.

A valve grinding machinery that grinds the surface of a workpiece with a lapping tool coated or embedded with abrasive. It is mainly used for grinding high-precision plane, internal and external cylindrical surface, conical surface, spherical surface, threaded surface and other profile surfaces.

Grinding is an important processing method in ultra precision machining, which has the advantages of high precision and wide range of materials. However, traditional grinding has some disadvantages such as low efficiency, high cost, unstable precision and quality, which limits the application of traditional grinding.

It solves most of the shortcomings of traditional grinding and improves the level of grinding technology. While ensuring the grinding accuracy and processing quality (reaching nanometer level), it also significantly reduces the processing cost, improves the processing efficiency, makes the grinding technology more practical, is conducive to the promotion and application of grinding technology, and promotes the progress of China's precision processing technology and advanced manufacturing technology, Enhance China's competitive power in the field of processing and manufacturing.

Main working principle of valve grinded machine: after power on, the motor decelerates through two-stage pulley, driving the first stage planetary reducer to decelerate again, making the speed of the actuator arm reach 55round / minete, and driving the suction cup to rotate in a uniform circle. At the same time, the first stage planetary reducer drives the second stage planetary reducer, and decelerates the 8mm shaft sleeve connected with the second stage planetary reducer to 27.5round/minete, so that the shaft sleeve and the actuator arm rotate in the same direction and at the same speed, and the upper convex head of the shaft sleeve and the actuator arm cooperate. When they rotate in the same direction and at the same time, because of the speed difference, the actuator arm moves in the same speed and at the same time slides up and down at the height of 8mm.

In this way, when the point machine is working, the actuator arm will do 55round / minete uniform circular motion and 8mm up and down sliding at the same time, so that the rubber suction cup on the actuator arm will drive the valve, so as to achieve the purpose of grinding the valve.
