Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a grinding device for removing casting sand, scale, burrs, etc. from the surfaces of forged products, cast products, etc.

(Prior Art) A blast machine described in Japanese Utility Model Application No. 55-93454 has been proposed as a conventional polishing device. This device is equipped with a large table, a plurality of small tables placed on the table, and a plurality of product tables placed on the small table, each of which is installed in a cabinet. It is. Then, the large table is driven and rotated by an electric motor, the small table is driven by a transmission means such as a belt that transmits this driving force, and the product table is rotated by a radial impeller.
The abrasive material is sprayed from a blast nozzle inside the cabinet to clean the rotating product.

(Problems to be solved by the invention) The conventional example is a combination of three types of tables: a large table, a small table, and a product table.
Moreover, since the small table is incorporated into the large table and the product table is incorporated into the small table, the structure becomes complicated. Since the rotation of the product table is determined by the rotation of the small table, the rotation of the product table cannot be maintained arbitrarily, making it difficult to achieve uniform finishing accuracy. Furthermore, since it is necessary to load and unload each product individually,
Its processing capacity was low.

The purpose of the present invention is to have a simple structure, to achieve uniform finishing accuracy, and to improve the processing capacity of the product.

(Means for solving the problem) In the present invention, a cleaning device main body equipped with a cleaning chamber,
A base plate is provided which is capable of entering and exiting the above-mentioned grinding room and can freely run on a traveling rail, and a support table is provided on the base plate so as to be rotatable about a rotating shaft, and a rotary wheel is mounted on the rotating shaft. a rotary table base that is pivotally supported; a table rotation drive means for rotationally driving the support table; a mounting table for an object to be polished rotatably provided on the support table; and a table provided on the main body of the cleaning device; The apparatus further includes a mounting table rotation driving means for rotationally driving the mounting table. The rotational driving means for the table includes a motor and a transmission wheel that receives the rotational force of the motor and rotates the support table, and the transmission wheel can come into contact with the rotational wheel and is rotated by the rotational wheel. It transmits power. The rotation driving means for the mounting table includes a motor provided separately from the motor, and a rotational force transmitting means that can receive the rotational force of the motor and come into contact with the outer peripheral surface of the mounting table.

(Function) When cleaning, the rotary table base is moved along the rail into the cleaning chamber of the main body of the cleaning device to a predetermined position, the rotary wheel is brought into contact with the transmission wheel, and the motor is driven there. The support table of the rotary table base is rotated by the rotation of the support table, and the mounting table that revolves due to the rotation of the support table has a relationship with the rotation of the support table because its outer peripheral surface comes into contact with the rotational force transmission means to which the rotational force of the motor is transmitted. At this time, the object to be polished on the mounting table is polished by the supplied abrasive material.

(Example) Examples of the present invention will be described below.

Grinding chamber 1 of cabinet 1 which is the main body of the grinding device
A traveling rail 2 is laid on the base 1b at the inner bottom of the cabinet, and this rail is extended outward (to the left in Figure 1) from an entrance opened in the side wall of the cabinet, and is connected to the base 1b. It is installed on the adjacent base 1c. A rotary table base 3 is disposed on this rail so as to be freely movable.

This rotary table base has rollers 3 provided on the base plate 3a.
It travels on rail 2 by b. A rotary shaft 3c is rotatably erected from the base plate 3a of the rotary table base, and a disc-shaped rotary wheel 3d is integrally supported at the base of the rotary shaft. and rotating shaft 3c
Two support tables 3e and 3f are attached in two stages, upper and lower, and both support tables are driven by the rotation of a rotating shaft 3c. On the upper surface of the support table, a plurality of mounting tables 4 are arranged in series and rotatably around the center of rotation. A sleeve-shaped product 5, which is an object to be polished, is placed and held on each mounting table.

A motor 6a, which serves as a drive source for a table rotation drive means 6 of the rotary table base 3, is attached to the outer part of the lower part of the cabinet 1. A drive wheel 6b of this motor and a transmission wheel 6 provided in the cleaning chamber 1a
A belt 6d is looped between it and c. The rotational force of the transmission wheel 6c can be transmitted to the rotary wheel 3d of the rotary table 3 that has moved into the cleaning chamber 1a.

In addition to the motor 6a, a motor 7a is attached to the upper part of the cabinet 1, and serves as a drive source for a rotary drive means 7 dedicated to the mounting table 4. Transmission shafts 7b and 7c, which are interlocked with the output shaft of the motor 7a, are vertically provided on both sides of the outer wall of the cabinet. Belt pulleys 7d and 7e are horizontally supported on each transmission shaft 7b and 7c at a level corresponding to the support tables 3e and 3f. Belt wheels 7d facing horizontally
and 7d, belt 7f between 7e and 7e (Figure 2)
It is hung around. Each belt 7f has a cleaning chamber 1
The outer circumferential surface of the mounting base 4 held on the rotary table base 3 that has moved into the space a can be brought into contact with the rotary table base 3, and
Due to this contact, the mounting table is driven to rotate.

A spray nozzle 8 is provided in the cleaning chamber 1a as a device for spraying abrasive material onto the product 5. Also, base 1
Hoppers 9 and 9a for collecting used abrasive materials are provided at the lower portions of b and 1c.

A cyclone hopper 10 for dust collection is provided at the top of the cabinet 1. The entrance to the cabinet 1 is opened and closed by a door 11 that slides up and down.
This door moves up and down by the operation of the air cylinder 12.

We will explain how to use this device.

First, the rotary table 3, which is located at the position shown by the solid line in FIG. 1, that is, outside the cabinet 1, is moved from the entrance into the cleaning chamber 1a, stopped at a predetermined position (dotted line position), and fixed at that position. . Therefore, when the upper and lower motors 6a and 7a are operated, the rotational force of the lower motor 6a is transferred to the belt 6d and the transmission wheel 6c.
and is transmitted to the rotating shaft 3c via the rotating wheel 3d,
For this purpose, the support tables 3e, 3f rotate.
As a result, the mounting table 4 on the support table revolves around the rotating shaft 3c, and at the same time, the motor 7a
Since it contacts the belt 7f which is being driven by the belt 7f, it rotates due to the frictional force. At this time, the abrasive material is injected from the injection nozzle 8 toward the inner and outer peripheral surfaces of the sleeve-shaped product 5, and the surface of the product is sequentially polished by the abrasive material.

When the cleaning work is finished, open the entrance door 11.
The rotary table base 3 is opened, the rotary table base 3 is moved backward, and the next rotary table base is moved into the cleaning chamber, and the cleaning work is performed in the same manner as described above. The rotating table base is replaced automatically.

In the above example, the support table of the rotary table base 3 is
Although there are stages, it may be one stage, or three or more stages. The motor 6a of the support table of the rotary table base may be installed on the rotary table base. The rotational drive source of the mounting table is the drive source 6 described above.
If it is a different system, the belt 7f may not be used.

(Effects of the invention) As explained above, according to the present invention, a rotary table base and a mounting base are combined, and the rotation of the mounting base is not dependent on the rotation of the rotary table base, so compared to the conventional example. The structure is simple and the finishing accuracy can be made uniform. Since only the rotary table stand, which is independent of the table rotation driving means, can be taken in and out of the cleaning room, products can be processed all at once, thereby increasing the product processing capacity.
