Embodiment Construction

[0021] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Figure 1 to Figure 3 Shown is one embodiment of the cylinder head valve automatic grinding device of the present invention.

[0023] see figure 1 , figure 2 , the cylinder head valve automatic grinding device includes a support frame 1 supporting the cylinder head 2, a lifting rod 4 installed on the bottom end of the valve 3 of the cylinder head 2 and raising the height of the valve 3, and the lifting rod 4 is rotatable The connected fulcrum base 5 drives the lifting rod 4 to swing up and down.

[0024] When the cylinder head valve automatic grinding device is in operation, after the lifting rod 4 lifts the valve 3 to the highest point, the part of the lifting rod 4 acting on the valve 3 drops rapidly, and its descending speed is faster than the descending speed of the valve...

Abstract

The invention relates to the technical field of internal combustion engine repairing, in particular to an automatic grinding device of a cylinder head valve. The automatic grinding device of the cylinder head valve comprises a support used for supporting a cylinder head, a lifting rod acting at the bottom of the valve of the cylinder head and lifting the valve, a pivot seat rotatably connected with the lifting rod, and a power device driving the lifting rod to swing up and down. When the automatic grinding device of the cylinder head valve is operated, the dropping speed of the part where the lifting rod acts is higher than that of the valve. By the aid of the automatic grinding device of the cylinder head valve, the problems that working intensity in grinding of the cylinder head valve is high and efficiency is low can be solved.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine repair, in particular to an automatic grinding device for cylinder head valves. Background technique [0002] During the use of the internal combustion engine, the valve seat of the cylinder head and the valve switch on and off, and numerous collisions will occur in one service cycle. The strong impact will cause different degrees of wear and tear on the valve port, which will seriously affect the tightness of the valve and directly reduce the internal combustion engine. usage performance. Therefore, in each repair cycle of the internal combustion engine, the part must be processed and repaired to restore the tightness of the valve. [0003] According to the past repair method, the valve and valve seat are repaired by machining. Since the parts must have precision errors during machining, when the repaired valve is installed on the valve seat, the angle error of the valve or t...
