Abstract
The utility model discloses a hydraulic pressure, the sealed protection device of cover that rises of atmospheric pressure frock, including apron, sealed rubber ring, protection cover that rises, base and assembly screw, compare with prior art, the utility model provides a hydraulic pressure, the sealed protection device of cover that rises of atmospheric pressure frock utilizes thin white iron to do cyclic annular apron, and structural shape will have big elastic space, including wrapping up the base top simultaneously, and satisfy the activity space between cover and the base that rises, adopts the thin soft gasket preparation of softer rubber, because its material is softer, elasticity is better, touches the base in the course of the work and can not cause the damage yet, can effectually cover the clearance, within preventing that impurity etc. from falling into, cause the damage to the fitting surface, prolonged the life of frock.
Description
Technical Field
The utility model relates to a hydraulic pressure, atmospheric pressure frock cover sealing protection device that rises belongs to the frock clamp field.
Background
The hydraulic expansion sleeve tool is fixed with a machine tool by a base, and the middle of the base is provided with a clamping mechanism which is composed of a clamping expansion sleeve, a hydraulic cylinder, a pull rod, an expansion sleeve guide block and the like. The existing hydraulic expansion sleeve clamp has the process that an expansion sleeve moves downwards and inwards simultaneously when clamping a workpiece, external impurities or processing waste materials easily enter a gap between the expansion sleeve and a base when working, cannot be automatically removed, manual processing can be very troublesome, if the damage of a matching surface is not protected, the processing precision of a tool and the workpiece is influenced, the service life of the tool is shortened, and the production cost is increased.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a hydraulic pressure, atmospheric pressure frock cover sealing protection device that rises to solve the problem that easily falls into waste material and magazine between cover and the base that rises, better protection hydraulic pressure frock.
The utility model discloses the technical problem that will solve adopts following technical scheme to realize:
the sealing protection device for the expansion sleeve of the hydraulic and pneumatic tool is characterized by comprising a cover plate, a sealing rubber ring, a protective expansion sleeve, a base and an assembly screw, wherein the protective expansion sleeve and the base are matched with each other to form a gap, the cover plate and the sealing rubber ring are sequentially stacked above the protective expansion sleeve and the base, bolt holes are formed in the protective expansion sleeve, the cover plate and the sealing rubber ring, the assembly screw sequentially penetrates through the cover plate, the sealing rubber ring and the protective expansion sleeve to fixedly connect the cover plate, the cover plate is an annular cover plate, a through hole is formed in the center of the cover plate, and a blocking part is arranged on one inward side of the outer circumference of the through hole.
Further, the blocking thickness is larger than the thickness of the sealing rubber ring.
Further, the cover plate is made of a thin white iron material.
Further, the sealing rubber ring is made of a thin rubber gasket.
The utility model has the advantages that:
the utility model provides a hydraulic pressure, the sealed protection device of atmospheric pressure frock cover that rises, utilize thin white iron to do cyclic annular apron, structural shape will have big elastic space, including wrapping up the base top simultaneously, and satisfy the activity space between cover and the base that rises, the rubber ring adopts the thin soft gasket preparation of softer rubber, because its material is softer, elasticity is better, it can not cause the damage to touch the base in the course of the work, can effectually cover the clearance, within preventing that impurity etc. from falling into, cause the damage to the fitting surface, the life of frock has been prolonged.

Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the present invention will be further explained below with reference to the following embodiments and the accompanying drawings, but the following embodiments are only the preferred embodiments of the present invention, and not all embodiments are included. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention.
The utility model provides a hydraulic pressure, atmospheric pressure frock rise cover sealing protection device which characterized in that, including apron 1, sealed rubber ring 2, protection rise cover 3, base 4 and assembly screw 5, wherein cooperate each other between protection rise cover 3 and the base 4 and constitute the clearance, apron 1, sealed rubber ring 2 stack in proper order and place in the top of protection rise cover 3, base 4, wherein are equipped with the bolt hole on protection rise cover 3, apron 1 and the sealed rubber ring 2, assembly screw 5 passes apron 1, sealed rubber ring 2 and protection rise cover 3 in proper order and is fixed connection with it, apron 1 is the annular apron, and its central through-hole that is equipped with is inside one side to the outer circumference of through-hole to be equipped with separation 6.
As the utility model discloses a further improvement, 6 thickness of separation are greater than the thickness of sealed rubber ring 2, and 6 can effectual protection edgewise sputtered impurity etc. of separation prevent that it from getting into the life that the clearance influences the frock.
As a further improvement of the present invention, the cover plate 1 is made of a thin white iron material.
As a further improvement of the present invention, the sealing rubber ring 2 is made of a thin and soft rubber gasket.
The utility model discloses 2 laminating of rubber ring seal rise the top surface of cover 3, then cover apron 1, both all add the top of covering 3 rising, fix it through 3 top bolt holes of cover 5 that rise. The effective protection of the contact surface of the base 4 and the expansion sleeve 3 is finished, the penetration of impurities such as cutting fluid and the like can not be caused in the using process, the base 4 and the expansion sleeve 3 are effectively protected, the service life is prolonged, the use precision is protected, and the use value is improved.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
