Ball type polishing machine with built-in load meter

A ball-type polishing machine with a built-in load cell, in particular, a ball-type polishing machine with a built-in load-bearing member and a spring mechanism for supporting the weight of the part supporting the ball-shaped workpiece.

With the advancement of technology and the refinement of products, the application of molds in products has also increased. Because it is in the modern society where plastic products are popular, the precision requirements of products are getting higher and higher, so the manufacturing technology of the mold itself It will also increase relatively. In the manufacturing process of the mold, the finishing work on the surface of the mold also has a great influence on the appearance quality of the product. Therefore, how to improve the automation of the surface finishing work of the mold surface can be said to be an important issue in the future development of the mold industry.

Generally speaking, for the surface finishing work of the mold, it can be mainly divided into polishing, polishing and polishing, wherein the polishing process uses a soft ball type wool felt polishing ball at the front end of a spherical workpiece to fix the wool felt polishing ball. On the rotating shaft of the spherical workpiece, and making it contact with the workpiece, the grinding liquid circulation system is used to make a small amount of cutting work on the surface of the material. And the polishing process needs to consider the processing parameters such as abrasive, rotation speed, feed rate polishing liquid, processing pitch and pressure depth.

However, in the polishing process, the ball felt ball of the spherical workpiece only needs to apply a small contact force to the surface of the workpiece (for example, 0.4 Newton (N)) to avoid the problem of pressure depth; however, the ball workpiece itself The weight will generate a large load (for example, the load of the spherical workpiece is 5 Newtons (N)), which results in the traditional ball-shaped workpiece designing a weight mechanism to overcome the excessive load of the spherical workpiece. The problem of the pressure depth generated; and the design of the weight mechanism causes the volume of the spherical workpiece to be too large, resulting in a large working space.

In view of the above problems, the present invention provides a ball-type polishing machine with a built-in load cell, by which a load-bearing member is integrated into a ball-type polishing machine, so that the load-bearing member can sense the force above a workpiece; The spring can ride the first housing and the second housing, and the second housing is coupled to a spherical workpiece to achieve the weight of the spherical workpiece through the first spring.

A ball-type polishing machine with a built-in load meter according to the present invention includes a tool holder, a first housing, a second housing and a first spring. The shank is internally provided with a pressing member, and a load bearing member is disposed above the pressing member, and the shank is sleeved with a first spring; the first housing sleeve covers the first spring and the shank, so that the shank can be Moving in a longitudinal direction (eg, upper and lower) of the first housing and relatively pressing the first spring, and the first connecting portion of one end of the shank extends out of the first housing for fixed connection with a preset control device The second housing is coupled to the first housing in a reverse direction to be coupled, and the second housing is coupled to the predetermined spherical workpiece.

The utility model has the advantages that the load component is integrated into the spherical polishing machine, so that the load component senses the force relative to the spherical workpiece and the workpiece; in addition, a preset control device is fixedly connected by the handle (eg: Automatically controlling the device, so that the first spring can be used to carry the first housing and the second housing, and the second housing can be coupled to the preset spherical workpiece, so that the first spring can be used to load the spherical workpiece. The weight, overcoming the spherical workpiece itself, is too large, which will cause the pressure depth problem in the polishing process; at the same time, the design of the weight mechanism of the conventional ball type workpiece can be eliminated, and the volume of the spherical workpiece can be prevented from being excessively large.

Fixing the component and locking the locking component to the bottom until the locking component contacts the bottom surface of the expansion portion 14 of the shank 10 and recording the length of the locking component locking (ie, the locking snail) The distance is [X1); after that, the calculation formula F=K*X2 is used, where (F: is the maximum force that the load member 17 can bear); (K: the spring constant of the second spring 153 is selected); A maximum distance X2 is obtained. Thus, when X1 is smaller than X2, the load member 17 can be prevented from being damaged by a large impact.

The first through hole 141 of the expanding portion 14 and the second through hole 421 provided on the bottom surface 42 of the second casing 40 may be sequentially provided with a spigot. When the polishing process is performed, the shank 10 is fixed in a fixed state. The second housing 40 can be restricted from rotating by the insertion end, so that the second housing 40 and the first housing 20 can be prevented from being unscrewed and detached.

When the shank 10 is engaged with the first housing 20, the first bearing 16 and the second bearing 26 can be used as a buffer between the two, and the friction between the shank 10 and the first housing 20 is reduced to The smallest.

The second housing 40 is provided with a plurality of second locking holes 45 at a position relative to the fourth opening 43. The locking member can be locked by the second locking hole 45, so that the first housing 20 and the second housing 40 can be stabilized. combination.
