Functions to adapt to the operational requirements of producing different products, thereby improving the scope of application and practicability of the polishing machine.

Generally, polishing machines for polishing the surface of articles are mainly divided into two categories: grinding wheel belt polishing machine and cloth wheel polishing machine due to different purposes. No matter what kind of polishing machine it belongs to, it can polish the surface of articles; but different The scope of use of polishing machines has its own limitations; therefore, in the use of polishing articles, there will also be defects of varying degrees, which are described below:

The cloth wheel polishing machine is mainly on the frame, and the two ends of the transmission shaft driven by a driving motor are combined with two sets of cloth wheels to provide surface polishing for the article. However, although this polishing machine It can provide articles for polishing, but because the cloth wheel used for processing and polishing only has a polishing effect on the surface; so that when the surface of the processed object has sand holes, the sand holes cannot be properly ground and repaired, and it must be polished. Mark the sand holes of the workpiece, and stop polishing. After a certain amount has been accumulated, then grind the work with sand holes, and then continue to polish the surface. The whole operation is very troublesome and time-consuming. , is not practically beneficial.

The grinding wheel belt polishing machine (see Figure 1) is on the side of the frame 2 of the cloth wheel polishing machine, combined with a support rod 21 extending backwards, and an idler wheel 22 is vertically pivoted at the end of the cloth wheel polishing machine, and then matched with The grinding wheel belt 23 is combined together; the cloth wheel 25 combined on the transmission shaft 24 of the frame 2, and the idler wheel 22 pivoted on the support frame 21 are formed by the grinding wheel belt 23. Continuous rotary motion is used for polishing and grinding the surface of the article. However, because the wheelbase between the cloth wheel 25 and the idler wheel 22 is fixed, the following disadvantages will occur during the polishing operation:

1. Because the grinding wheel has a certain size, and the wheelbase of the cloth wheel and the idler wheel is fixed, so that when the workpiece is replaced and has a different curvature, the cloth wheel and the idler wheel of the polishing machine must be replaced at the same time ( See Figure 2), which causes inconvenience in the replacement operation.

2. The processing surface is located on the front side of the frame, so that the position between the cloth wheel and the idler wheel is difficult to provide for polishing. Even if it is used, it is extremely uncomfortable, and the shape of the processed object is limited, which reduces its scope of application.

3. Since the wheelbase of the cloth wheel and the idler wheel is fixed, the tightness of the grinding wheel belt cannot be adjusted properly, so that the grinding wheel belts with different widths cannot be used in the same cloth wheel set.

Because the traditional polishing machine still has many of the aforementioned disadvantages, which narrows its scope of application, increases the difficulty of operation, and is time-consuming to operate and use, the utility model eliminates many disadvantages, mainly lies in the support device used to support the grinding wheel belt, which has the ability to adjust The center distance between the cloth wheel and the idler wheel, and at the same time, the supporting device can be rotated appropriately to adapt to a single cloth wheel replacement and change of processing position.

The main purpose of this utility model is to provide an improved structure of the polishing machine with adjustable wheelbase and idler wheel, so that the user can easily replace the cloth wheel and adjust the tightness of the grinding wheel belt at the same time.

The secondary purpose of the utility model is to provide an improved structure of the polishing machine with the position adjustment of the idler wheel, so as to change the processing position of the operator, so as to obtain a better polishing processing area and improve the scope of application of the workpiece .

The utility model is a polishing machine with improved structure, which mainly includes a frame with a transmission shaft, a driving motor and a control device. The support device is combined with an idler at the end; the support device includes a support rod and a guide sleeve that fit inside and outside, and the end of the support rod is combined with a horizontal support seat, and a lateral displacement adjustable The shaft is combined with an idler wheel that can rotate freely; the front section of the guide sleeve is provided with a screw hole facing forward, and the front end is pivotally provided with an adjustment screw, the end section of the adjustment screw is screwed with the aforementioned screw hole, and the front section is the adjustment part It protrudes from the guide sleeve to adjust the rotational movement of the drive screw; the outer diameter of the rear section of the guide sleeve is bolted with more than one bolt through the interior; the adjustment screw rotates to drive the support rod to move forward and backward to adjust the wheelbase between the idler wheel and the drive shaft .
