Description

Triaxial polishing machine

This creation relates to a polishing machine, especially a three-axis polishing machine.

For example, the new patent of the Republic of China Patent No. 124283 discloses a "grinding and polishing machine". The conventional polishing machine shown in the first figure is a hand-held work piece, and the grinding wheel is ground according to the desired polishing position. In order to achieve the effect of polishing the workpiece, but the polishing efficiency of the hand-held workpiece is not good, so the improved chain frame is placed on the main and moving gear turntable, and the combination frame is locked and locked on the chain frame. The tube rotates and protrudes from the mandrel, and a bearing is inserted into the working piece at the middle portion of the mandrel, and the workpiece is moved by the combination frame for grinding and polishing. However, in order to be able to set a plurality of working pieces to be polished during the moving process, the combination frame is inevitably bulky, and since the grinding wheel is fixed and the working piece is only displaced according to a fixed path, the surface on which the workpiece is ground is only suitable for regular shapes (eg The figure shows a cylindrical surface), which can achieve a uniform grinding and polishing effect. If the workpiece is ground in an irregular shape, it is not applicable.

Another example is the new patent of the Republic of China Patent No. M382870, which discloses a "multi-angle dynamic polishing structure" in which the shaft of the workpiece is rotatable and can be displaced in a three-dimensional axial direction (XYZ), so that the surface can be irregularly shaped. Grinding and polishing, and the shaft provided by the polishing wheel can be adjusted in angle and can be replaced with different polishing wheels, as shown in the figure for grinding and polishing the upper surface of the workpiece. However, if the side surface of the workpiece is to be polished and polished, the workpiece must be re-fixed to face the polishing wheel, and the action of re-fixing the workpiece will increase the polishing operation, resulting in a polishing operation. The problem of poor polishing efficiency occurs.

In addition, the above-mentioned conventional polishing equipment has the same problem in grinding and polishing. When the polishing wheel is rotated and polished, if the polishing area of the polishing wheel is larger than that of the polished object, the loss of the contact grinding portion is longer than that of the non-contact polishing portion. The polishing surface of the polishing wheel is not uniform. If the polishing wheel is used for grinding and polishing other objects, the surface to be polished may cause uneven polishing effect.

Therefore, how to solve the problem of the above-mentioned conventional polishing equipment is the focus of this creation.

One of the purposes of the present invention is to solve the above problems and provide a three-axis polishing machine, which can grind and polish the surface of an irregularly shaped workpiece, and can grind and polish the plurality of surfaces of the workpiece in one process to achieve Good polishing efficiency.

The second purpose of the present invention is to provide a second polishing assembly provided by the longitudinal polishing unit, wherein the polishing belt can be driven to reciprocate along the Y-axis during grinding to prevent the grinding surface from being irregular and to avoid the surface on which the workpiece is ground.

As shown in Fig. 11, when the top 55 of the door handle 5 is ground and polished, the longitudinal polishing unit 4 is displaced in the Z-axis by the longitudinal slider 45, so that the grinding side B is raised to the height of the top 55 of the door handle 5, And displaced in the Y-axis by the transverse slide 42 so that the grinding side B contacts the top 55 of the door handle 5, and the first slide 422 reciprocates along the Y-axis as previously described, with the door handle 5 along the table 2 moving in the X-axis direction causes the grinding side B to polish the top portion 55, and the longitudinal sliding portion 45 is displaced in the Z-axis direction so that the grinding side B is tapered along the aforementioned top portion 55 and moves in the contour of the intermediate projection. The top 55 can be uniformly polished and polished.

The grinding side A of the first polishing assembly can be polished not only along the plane of the side 52 or the top 55 of the door handle 5 as previously described, but if both the side 61 and the top 62 of the workpiece 6 are to be ground, In the curved shape, when the workpiece moves along the X-axis, as shown in FIG. 12, the grinding side A of the first polishing assembly is controlled to be displaced in the Y-axis along the curved side 61 of the workpiece 6 to The side edge 61 is ground, and as shown in Fig. 13, the grinding side B of the second polishing assembly is controlled to be displaced in the Z-axis along the curved top portion 62 of the workpiece 6 to grind the top 62 of the door handle to Achieve the grinding effect of the curved edge.

It is not difficult to find out from the above that the advantages of this creation are:

1. Since the table 2 is linearly displaceable along the X axis on the base 1, and the two lateral polishing units 3 can be operated by the first traverse mechanism and the first aligning mechanism, the first polishing assembly Displaced along the Z axis, and can be displaced along the Y axis along with the first traverse mechanism, and can be polished along the contour of the sides of the workpiece, and the longitudinal polishing unit can be coupled by the second traverse mechanism and The second priming mechanism operates to displace the second polishing assembly along the Z axis and is displaceable along the Y axis with the second traverse mechanism and can be polished along the top contour of the workpiece. Therefore, the three-axis polishing machine of the present invention can grind and polish the surface of the irregularly shaped workpiece, and can grind and polish the plurality of faces of the workpiece in one process, compared with the conventional polishing machine. The process of replacing the surface to be ground and re-fixing the workpiece can be saved, so that the polishing operation can be achieved with good efficiency.

2. When the second polishing assembly is ground and polished, since the grinding area of the polishing belt 49 is larger than the width of the polished door handle 5, the polishing wheel grinding surface is prevented from being caused by the contact grinding portion and the non-contact polishing portion during the polishing and polishing. The problem of the irregularity is that the second polishing assembly provided by the longitudinal polishing unit 5, when the polishing belt 49 is rotated, is pulled by the connecting rod 426 by the eccentric shaft 425a to drive the first sliding seat 422 along the Y. The axial reciprocating slip causes the grinding area of the polishing belt 49 to grind and polish the top 53 of the door handle 5, and can prevent the surface of the grinding belt 49 from being unevenly formed to avoid the surface of the workpiece being polished. Uniform problem.

Of course, there are still many examples of this creation, only the details change. Please refer to FIG. 14, which is a second embodiment of the present invention. The main difference from the first embodiment is that the first polishing assembly of the embodiment has the driving wheel 381, the guide wheel 371 and the auxiliary wheel 372 modified. The axial direction is the longitudinal direction and the flat belt 39 is wound around the driving wheel 381, the guide wheel 371 and the auxiliary wheel 372 in the lateral direction, and the same effect as that of the first polishing assembly of the first embodiment can be achieved.

The above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the scope of the present invention.

From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the aforementioned objectives, and has been in compliance with the provisions of the Patent Law, and has filed a patent application.
