Description

Combined wiper and screw device having the same

The present invention relates to a screw member, and more particularly to a combined wiper and a screw device having the same.

The screw member such as a ball screw mainly includes a screw, a nut, and a ball, wherein since the screw is threaded through the nut and screwed on the screw, there is a matching gap between the two, so that the screw and the nut are opposed to each other. When moving, external dirt or metal fines easily invade the matching gap between the two and affect the movement of the ball screw. Therefore, the conventional ball screw is provided with a wiper between the screw and the nut to generate a scraping action, thereby maintaining the cleaning on the screw and the smoothness of movement with the nut.

However, the conventional wiper is annular and looped on the screw. When the repair and replacement are to be performed, since the screw is fixed to the fixed seat and the support base of the machine, the wiper cannot be directly removed at all. The screw must be detached from the fixing seat and the support seat, so that the squeegee can be removed, which is extremely inconvenient and troublesome, and even quite time-consuming and laborious, and has long been plagued by people.

The creator of this case thought that the wiping ring could be improved into a combined type, but the brush ring that was changed into a combined type would have a structural strength that was greatly weakened and easily deviated and decomposed.

Therefore, how to design a combined wiper that is not easy to be disengaged and decomposed and has The screw device of the brush scraper is a major subject that the creator of the present invention wants to solve.

The purpose of the present invention is to provide a combined wiper and a screw device having the same, which can be separately removed by a combined design, and it is completely unnecessary to remove the screw from the machine table for convenient maintenance. And replacement, plus the design of the positioning ring to enhance the structural strength of the wiper ring without being easily disengaged or disassembled.

To achieve the above object, the present invention provides a combined wiper comprising: a wiper ring comprising a plurality of components that are detachably assembled to each other in a ring shape; and a positioning ring that is coaxially fixed Within the positioning ring.

The present invention further provides a screw device having a scraper, comprising: a screw; a nut disposed on the screw; and a scraper disposed at one end of the nut and screwed to the screw The wiper includes: a wiper ring including a plurality of components that are detachably assembled to each other in a ring shape; and a positioning ring that is coaxially fixed within the positioning ring.

Compared with the prior art, the creation has the following functions: the squeegee can be removed separately, and the screw is not required to be removed from the machine table, which is convenient for maintenance and replacement; and the structural strength of the squeegee ring can be improved without being easily disengaged or break down.
