Description of the Related Art An error absorbing device is mounted between a robot and a chuck, and a robot mounting plate and a main body move in a horizontal direction or a twisting direction in order to absorb a misalignment between a workpiece clamped by the chuck and the robot. Therefore, a gap is formed between the robot mounting plate and the main body, and foreign matter such as dust or cutting chips may be bitten into it, resulting in malfunction. Therefore, conventionally, packing is provided to seal the gap to prevent dust from entering. Since there are few kinds of packing on the market, the price is high and the size is limited. In addition, manufacturing the packing for exclusive use increases the manufacturing cost. Until now, there was a method of sealing with an O-ring, but since it seals on the groove side,
The resistance may have become too large, or dust may have entered and caused malfunctions.

The positioning error absorbing device comprises a robot mounting plate (1), a main body (2) and a chuck mounting plate (3). A robot side mounting portion (4) is formed on the robot mounting plate (1). A chuck side attachment portion (5) is formed in 3). A cylinder (6) is formed on the robot mounting plate (1), and a piston (7) and a pusher (8) are inserted therein. A slide base (9) and thrust bushes (10) on both sides of the slide base (9) are arranged between the main body (2) and the chuck mounting plate (3), and are configured to slide in the horizontal direction and the twisting direction. Slide base (9)
Are fixed to the robot mounting plate (1). The piston (7) receives fluid pressure in the cylinder,
The positioning block (11) pushes the steel ball (12) to position the chuck mounting plate (3). A gap is formed between the robot mounting plate (1) and the main body (2). In the dustproof method, steps (1A, 2A) are formed in the gap between the robot mounting plate (1) and the main body (2) in opposite directions, and an O-ring (13) is attached to the groove formed by the steps. ing.

により、安価でシール性の高い構造を得る事が出来る。FIG. 3 is an explanatory view of the packing seal.
As shown in FIG. 3A, a step is formed on the chuck mounting plate (1) and the main body (2), and the step constitutes a groove.
By inserting the O-ring (13) in the groove, the gap between the chuck mounting plate (1) and the main body (2) becomes smaller.
It is sealed by 3) and the inner surface of the groove to prevent dust and the like from entering the gap. FIGS. 3B and 3C show the case where the chuck side attachment portion (5) is moved in the horizontal direction. Since the chuck mounting plate (3) and the main body (2) move, the inner surface of the groove is dislocated,
Before the inner surface of the groove separates, the side surface of the groove is newly brought into contact with the O-ring, so that the gap is sealed. 4 (a), (b),
(C) shows a conventional sealing method. As shown in FIG. 4 (a), a method of sealing on the side surface of the groove is generally used, but since the O-ring is compressed, the resistance during sliding increases, which hinders the smooth movement of the error absorbing device. Therefore, the dimension of the groove is designed so as to slightly contact the side surface of the groove. However, due to variations in machining tolerance, variations in O-ring temperature, etc., a gap is created as shown in FIG. It is the cause of entering. As described above, as a dustproof method for the positioning error absorbing apparatus, a step is formed on each surface of the gap and the O-ring is inserted into the groove, so that an inexpensive and highly sealable structure can be obtained.
