Wheel grinder

This creation is about a machine tool for grinding and grinding, especially a wheel mill.

The traditional wheel grinder uses the principle of the seesaw to control the tension arm to be clamped or released. However, after the assembly, the positioning hook button is directly exposed on the outside. In addition to affecting the appearance, it is also easy for the user to accidentally disassemble the belt. The condition of the misplaced positioning hook button occurred.

The ring belt type grinding tool of the invention patent No. I347871 has the structural design to improve the leakage and mis-touch of the above positioning hook. However, the domestic invention patent No. I347871 still has the following disadvantages, and the tension arm needs to be rotated one angle through the carding button and then turned back, which leads to problems such as complicated structure and difficult assembly.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

One of the aims of the present invention is to provide a pulley grinding machine which is mounted by a pulling assembly and slidable to a bottom surface, the steel ball is accommodated in the through hole and can select a ring groove or a card groove, so that the pulley grinding machine has It prevents the user from accidentally touching, easy to operate and easy to assemble.

In order to achieve the above object, the present invention provides a pulley grinding machine, comprising: a body comprising a set of seats, the sleeve having a lower end and a front end; a pneumatic motor fixed to the lower end, the The air motor has a driving pulley, and the driving pulley is accommodated in the sleeve; a positioning rod, The positioning rod has a distal end portion and a bottom surface, and the bottom surface is disposed on the same side as the lower end portion. The end portion is provided with a through groove, and the bottom surface is connected to the bottom portion. a through hole of the slot; a telescopic rod having a through-segment at one end and a driven pulley at the other end, the through-segment is slidably and slidable to the through slot, and the through-segment has a ring a groove spring; is disposed in the through groove, the tension spring is sandwiched between the positioning rod and the telescopic rod; a grinding ring belt, the two ends are respectively sleeved on the driving pulley and the driven belt And a switch assembly comprising a trigger assembly and a steel ball, the trigger assembly being mounted and slidable to the bottom surface, the trigger assembly being provided with a groove, the steel ball being received in the through hole and capable of selecting Ring groove or the card groove.

This creation also has the following effects:

First, the wheel grinder adopts a pulling and pulling component to control the tensioning or releasing of the grinding ring, and the telescopic rod needs to be pushed toward the positioning rod, and the steel ball will be stuck with the ring groove, thereby releasing the grinding ring band. The original belt wheel grinding machine has the characteristics of preventing the user from being accidentally touched and operating conveniently.

Secondly, the grinding ring belt must be taken away from the air motor, and the pulling component is mounted on the bottom surface, so the mounting position of the pulling component is opposite to the direction of disassembling the grinding ring belt, so that the user can more conveniently operate and assemble the pulley. The grinder has the advantages of easy operation and easy assembly.
