Description

Left and right yaw grinding machine

This creation relates to a left and right yaw type grinder.

Nowadays, there are many kinds of grinding machines, one of which is a left-right yaw type grinding machine, also called a grater grinding machine. The left-right yaw type grinding machine allows the grinding piece assembled on the horizontal direction to reciprocate in the horizontal direction for grinding.

However, in order to obtain the support and limit of the yaw arm that causes the horizontal reciprocating motion of the grinding member, the right and left yaw grinding machine now embeds the direction restricting member in the housing, and installs a universal bearing through which the restriction member is restrained. The yaw arm is actuated in direction and the yaw arm is supported by the universal bearing.

However, in the present case, the direction restricting member is knocked into the casing by using a hand tool such as a hammer, and the direction restricting member may cause an erroneous assembly result due to an erroneous force applying direction or a force direction when striking, and is likely to cause assembly time. increase. Moreover, the direction restricting member is easy to be worn out under long-term use and needs to be replaced, but the direction restricting member is assembled in an embedded manner, which is disadvantageous for disassembly and replacement. In addition, although the universal bearing can support the yaw arm, the size of the universal bearing is too large, so that the head of the left and right yaw grinding machine cannot be reduced, and the user's visual field of view is hindered. . Furthermore, the fixing of the universal bearing is not easy.

The main purpose of this creation is to solve the problems that the existing structure derives from the implementation of the universal bearing structure.

The secondary purpose of the present invention is to solve the problem that the existing structure is not conducive to the rapid assembly of the direction restricting member in the hollow casing.
