Valve grinder with limited processing capacity

Abstract

The invention discloses a valve grinder with the limited processing capacity. The valve grinder comprises a grinding device, wherein the grinding device is arranged on a groove beam which can lift up and down and is horizontally arranged; a rack plate which slides left and right along the groove beam is arranged at the middle part of the groove beam and is matched with a small gear on the grinding device; one end of the rack plate is connected with a crank-guide rod-sliding block mechanism on a stand; the stand is also provided with a control system which limits the grinding processing capacity; and the control system is composed of an infrared transmitting and receiving device, a counter, a PLC, a relay and a motor and controls the grinding capacity by controlling the running state of the motor according to the number of round trips. According to the valve grinder, the grinding capacity of a valve seat can be automatically controlled, the use of manpower resources is reduced when high grinding accuracy and production efficiency are ensured, and the cost of processing the valve seat is lowered, so that the assembly quality of an engine is ensured, and the need of mass production is met.

Description

technical field [0001] The invention relates to a valve grinder, in particular to a valve grinder with limited grinding amount. Background technique [0002] In modern automobile manufacturing, the engine of the automobile is the most core component, and the grinding of valves and valve seats is also very important in the assembly and manufacturing process of the engine. If the valve seat is not well ground, the sealing effect of the valve will be poor, which will eventually lead to air leakage, which will affect the work of the engine. At present, for the grinding of engine valves and valve seats, electric, manual, pneumatic and other types of valve grinders are generally used in China for grinding, but the noise is large when the grinder is working, the grinding quality and efficiency are low, and most of the valves When the grinding machine grinds the valve, it needs experienced workers to stand by the machine at all times, which results in time-consuming and labor-inten...

Problems solved by technology

If the valve seat is not well ground, the sealing effect of the valve will be poor, which will eventually lead to air leakage, which will affect the work of the engine

At present, for the grinding of engine valves and valve seats, electric, manual, pneumatic and other types of valve grinders are generally used in China for grinding, but the noise is large when the grinder is working, the grinding quality and efficiency are low, and most of the valves When the grinding machine grinds the valve, it needs experienced workers to stand by the machine at all times, which leads to time-consuming and labor-intensive

In addition, there are still shortcomings such as human error in the control of the amount of grinding required for the valve seat.

[0003] At present, there are roughly two types of valve grinding machines on the market. One is a small portable electric valve grinding machine. This type of grinding machine has low power and narrow scope of application. Grinder, although it can grind multiple valves at the same time, has a complex structure, is not easy to operate, and has a high failure rate, and the cost is relatively high, so it is not easy to promote
