Description

Technical Field

[0001] The utility model relates to the technical field of grinding machine equipment, in particular to an engine valve forming grinding machine. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones, abrasive belts, and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinders, and polishers.

[0003] The application number is CN202222386921.9, which discloses a valve stem end face grinder, including a grinder base, a fixture assembly and a grinding assembly, wherein the fixture assembly includes a support rod, a horizontal plate, a vertical plate, a clamping plate A, a hydraulic cylinder A, a hydraulic rod A and a clamping plate B, a support rod integrally formed with the horizontal plate is fixedly connected to one side of the upper surface of the grinder base, a clamping plate A is fixedly connected to an outer wall of one side of the vertical plate, and the outer wall on the same side of the vertical plate and the clamping plate A is detachably connected to the hydraulic cylinder A by bolts; the valve stem end face grinder, by placing the valve stem in the symmetrical grooves on the clamping plates A and B, and then starting the switch of the hydraulic cylinder A, the hydraulic cylinder A drives the clamping plate B to approach the direction of the clamping plate A through the hydraulic rod A, and the two clamping plates are clamped and fixed after being brought together, and by starting the servo motor switch, the servo motor drives the transmission shaft B to rotate, and drives the vertical plate to rotate, and then adjusts the end face angle of the valve stem, thereby improving practicality.

[0004] A valve stem end face grinder disclosed in the above document has the following defects: when the grinder is grinding the valve stem end face, the motor of the grinder needs to drive the grinding assembly to operate at high speed. When the shaft of the motor of the grinder rotates at high speed, a large amount of heat will be generated at the connection between the shaft and the drive assembly in the motor. When the temperature of this heat is too high, the high temperature will overload the assembly, which will reduce the operating efficiency of the motor assembly. Finally, the motor affects the operating speed of the grinding assembly.

[0005] It can be seen from this that the existing valve stem end grinder does not have the function of cooling the motor shaft and internal components, and it is necessary to improve the existing deficiencies and provide a function that can cool the motor shaft and internal components.
