Problems solved by technology

In this case, the sliding resistance between the rod and the sleeve increases, and the rod cannot move in and out smoothly.
That is, since the force of the compression coil spring that moves the rod upward is very weak, the sliding resistance between the rod and the sleeve body prevents the rod from moving in and out smoothly.
Also, when the rod and sleeve body is damaged and worn, the durability is significantly reduced
[0007] In addition, when fine chips and dust adhere to the inner surface of the scraper, the cutting oil on the surface of the rod will easily penetrate into the inside.
Since the workpiece support is a structure that locks the rod through the friction force acting between the rod and the sleeve body, when cutting oil invades between the rod and the sleeve body, the friction between the rod and the sleeve body will Reduced force, reduced support function of the workpiece holder

Embodiment Construction

[0020] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0021] The workpiece holder 1 of this embodiment is as figure 1 As shown, it is a member for supporting the center part which supports the workpiece|work 2 from the lower side, and preventing the workpiece|work 2 from vibrating during cutting. like figure 2 As shown, the workpiece holder 1 includes: a substantially cylindrical case member 3; a rod 4; a hydraulic cylinder 5 for driving the rod 4; a shaft portion 6; a shaft member 7; compression coil springs 8 and 9; Made of the sleeve body 10 and so on.

[0022] First, the case member 3 will be described. like figure 2 , image 3 As shown, the case member 3 which is open from the lower end side to the upper exterior is composed of a case body 11 with both ends open and a case cover 12 fitted and fixed to the case body 11 . A rod receiving hole 13 is formed in the housing body 11, and a scraper 14 and a sealing me...

Abstract

There is provided a workpiece support whereby reliability of operation can be increased and durability can be enhanced. The workpiece support (1) comprises a rod (4), a sleeve body (10), a case member (3), a scraper (14), an external peripheral hydraulic chamber (22), and oil passages (34, 35, 36), and is further provided with an air passage (28) formed between the rod (4) and the internal peripheral surface of the sleeve body (10), and connected to the small gap between the rod (4) and the scraper (14), and an air input port (18) for supplying compressed air (50) to the air passage (28); wherein compressed air (50) is supplied from the air input port (18) to the air passage (28) and expelled from the small gap between the rod (4) and the scraper (14) when the rod (4) is retracted.

Description

technical field [0001] The present invention relates to a workpiece holder in which a rod is locked by elastically deforming an elastically deformable sleeve body by hydraulic pressure, and particularly relates to an improved structure for improving the operational reliability and durability of the workpiece holder. Background technique [0002] Conventionally, when cutting a workpiece or the like, a workpiece holder that locks and supports the workpiece, for example, on a workpiece pallet is actually used. The applicant of the present application has proposed to apply for various workpiece supports (also called hydraulic locking devices) (refer to Japanese Patent Application Laid-Open No. Sho 59-128902, Japanese Patent Application Laid-Open No. 6-47710, etc.) A proposal for a workpiece holder with a simplified structure. [0003] A workpiece support for simplifying the structure has: a rod; a sleeve body that is externally embedded on the rod and can elastically deform tow...
