Description

[Detailed description of the invention] (Industrial application field) This invention forms a long tubular body in a spiral shape and arranges it in upper and lower multiple stages and/or in multiple layers inside and outside to construct a barrel tank. A workpiece, an abrasive material, etc. (hereinafter, the mixture is collectively referred to as mass) are filled in the barrel tank, and the mass is caused to flow from the lower stage to the upper stage of the barrel tank and/or from the upper stage to the lower stage by applying vibration to the barrel tank. This relates to a barrel tank fixing device in a multi-stage tank vibrating barrel processing machine, which polishes the workpiece with an abrasive material while the workpiece moves from the bottom to the top and/or from the top to the bottom in the barrel tank. Belongs to the industrial field of manufacturing, sales and use of vibrating barrel processing machines.

(Prior art) Conventionally, in this type of multi-stage multi-barrel processing machine,
The inner cylinder and outer cylinder were integrated, and a barrel tank (small diameter pipe body) was assembled inside.

(Problems to be solved by invention) In the conventional barrel polishing machine mentioned above, it is necessary to work in a narrow space between the inner cylinder and the outer cylinder, so it takes a lot of effort and time to assemble it, and it is not fixed properly. There were problems such as the tendency to cause

(Means for solving the problem) However, in this invention, the inner cylinder is integrated, but the outer cylinder or the intermediate frame and the outer cylinder can be disassembled, and each stage is fixed at about three places, thereby improving the conventional method. This solved the problem.

In other words, this invention is based on a barrel processing machine in which a long tube with a uniform small diameter is spirally formed between an inner cylinder and an outer cylinder in multiple stages, or in multiple stages inside and outside. The inner cylinder and the outer cylinder, or the inner cylinder and the intermediate frame, and the semicircular parts of the semicircular blocks bored from the outer cylinder are brought into contact with each other, and the opposing flanges on the outside of the semicircular parts are brought into contact with each other. At the same time, the semicircular portion was fixed to the inner cylinder and the outer cylinder to complete a barrel tank fixing device.

Semicircular blocks are provided on the inner and outer walls of the intermediate frame at positions corresponding to the outer wall of the inner cylinder and the inner wall of the outer cylinder, respectively, and the flanges of the opposing blocks are tightened and fixed with bolts. A filler such as foamed plastic or sponge rubber is filled in the space between each polishing tank and the inner cylinder and outer cylinder, or between the inner cylinder, the intermediate frame, and the outer cylinder. Further, the long tube body is made of abrasion-resistant synthetic resin such as rubber, polyurethane, phenol resin, polyvinyl chloride, nylon, or the like.

(Function of the device) This device arranges a small-diameter long tube on the outside of the inner cylinder in multiple stages above and below, or multiple times inside and outside in multiple stages, and the long pipe is arranged on the outer wall of the inner cylinder, the intermediate frame, and the inner wall of the outer cylinder. Since the protruding semicircular block fixed the specified location, the fixing work was simple and reliable.

(Example 1) Next, an example of this invention will be described based on FIGS. 1 to 3. FIG. 1 is a front view of an embodiment of the invention, FIG. 2 is a plan view, and FIG. 3 is an enlarged cross-sectional view taken along line A--A in FIG.

This idea consists of an inner cylinder 1 and an outer cylinder 2 arranged concentrically.
A barrel tank 3 is constructed by winding long tubes 3a and 3b of uniform small diameter spirally in multiple stages, both inside and outside, between the inner tube 1 and the outer tube 2, and a foamed plastic 4 ( foamed polyurethane) or sponge rubber (e.g. neoprene sponge rubber)
is filled to completely envelop and fix the barrel tank 3.

A pair of eccentric weights 5, 5 are placed upwardly inside the inner cylinder 1.
A vibration motor 6 with a vibration motor 6 is mounted vertically, and these devices are suspended on a base 9 with a flange 7 by means of a number of springs 8,8.

The barrel tank 3 is composed of an outer elongated tube 3a and an inner elongated tube 3b.
The lower ends of a and 3b are connected to a stone discharge port.

Further, the upper end of the outer elongated tube body 3a is connected to the sorting net 1
9, and the upper end of the inner long tube body 3b is connected to a polishing return gutter 20 provided below the sorting net 19.

Next, the long tubes 3a and 3b are installed between the inner tube 1 and the outer tube 2 as described above, but before filling with foamed plastic, they are fixed at about three locations around the tube. There is a need. Details of this structure are illustrated in FIG.

First, the left semicircular block 17a is bolted to the inner cylinder 1, and the inner elongated tube 3b is wound spirally. Next, the right semicircular block 17b is bolted to the semicircular block 17a, and the intermediate frame 18 is bolted. Next, in the same manner as described above, the outer long tube body 3a is fixed by the semicircular blocks 17c and 17d between the intermediate frame 18 and the outer cylinder 2.

The long tubes 3a and 3b are made of wear-resistant synthetic resin such as rubber, polyurethane, phenolic resin, polyvinyl chloride, nylon, or the like.

In the above embodiment, the long tube was fixed at three points around the circumference of the tube, and a filler was filled between the inner tube and the outer tube to fix the long tube. However, if no filler is used, , it is necessary to fix the long tubular body at several points or more around the circumference of the tubular body.

In addition, in the above embodiment, there are multiple stages of upper and lower stages, two inner and outer stages, and
Although it is a double tank, the inner and outer tanks are single, double, triple...
etc., it is possible to adjust the one-round polishing time to a suitably selected value.

(Example 2) Next, based on FIG. 4, a case will be described in which the elongated tube bodies are arranged in multiple stages above and below.

This embodiment corresponds to the first embodiment in which the intermediate frame 18 is replaced with an outer cylinder.

That is, the left semicircular block 17a is bolted to the inner cylinder 1, and the inner elongated tube 3a is wound helically. Next, bolt the right semicircular block 17b to the semicircular block 17a, and
Bolt the outer cylinder 2 to 7b.

The outer cylinder 2 is divided into a predetermined number (for example, 2 to 4), and each division is fixed.

(Effect of the invention) That is, according to this invention, a long tube body spirally installed in multiple upper and lower stages or multiple upper and lower stages with multiple inside and outside sides is fixed with semicircular blocks, and each semicircular block is connected to an inner cylinder and an intermediate frame. Since it is fixed to the outer cylinder, the elongated tube body can be reliably fixed with relatively little effort and in a short time.
