Description
Technical Field
The utility model relates to a hydraulic clamping assembly, concretely relates to pipe mill hydraulic clamping assembly.
Background
In the prior art, a rolled pipe hydraulic clamping assembly generally consists of an external oil cylinder and a clamping component. The device is reasonable when being placed at the position of a clamping head of a pipe mill; however, if the hydraulic clamping assembly in the prior art needs to be placed at the lathe bed, the whole hydraulic clamping assembly is too heavy and unreasonable, the installation equipment is also inflexible, the installation is complicated, labor is wasted, and the work efficiency is seriously influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a hydraulically operated clamping assembly, its purpose aims at overcoming the above-mentioned not enough that prior art exists, through built-in hydraulically operated clamping assembly structure, simplifies the installation of the hydraulically operated clamping assembly of rolling pipe equipment lathe bed department, satisfies to roll a pipe lathe bed dolly and holds the steel pipe tightly.
The technical solution of the utility model is as follows: the hydraulic clamping assembly structurally comprises a chuck coaxially mounted on the outer side surface of a chuck inner sleeve, clamping claws are mounted on the inner side surface of the chuck inner sleeve, one end of the chuck inner sleeve is connected with a hollow piston, an oil cylinder barrel is mounted on the outer side surface of the hollow piston, an oil cylinder guide sleeve is mounted in a gap between the hollow piston and the oil cylinder barrel, an oil duct sliding ring is mounted on the outer side surface of the oil cylinder barrel, sliding ring bearings are respectively arranged between two ends of the oil duct sliding ring and the oil cylinder barrel, and a hydraulic oil interface communicated with the inner side is formed in the oil duct sliding ring.
Preferably, in order to clamp the steel pipe, the clamping jaws are 3 and are uniformly distributed on the inner side surface of the chuck inner sleeve in the circumferential direction.
The utility model has the advantages that: the pipe rolling machine has the advantages that the structural design is reasonable and compact, the mode of the built-in oil cylinder is adopted, the pipe rolling machine is more convenient and faster than the external structural mode in the prior art, the operation is more convenient, the technical problem that the steel pipe is tightly held by the pipe rolling machine body trolley is solved, the pipe rolling equipment can be mounted, and the pipe rolling machine is more convenient to mount and use.

Detailed Description
The present invention will be described in further detail with reference to examples and embodiments.
As shown in fig. 1, the hydraulic clamping assembly structurally comprises a chuck 1 coaxially mounted on the outer side surface of a chuck inner sleeve 2, clamping jaws 3 are mounted on the inner side surface of the chuck inner sleeve 2, one end of the chuck inner sleeve 2 is connected with a hollow piston 5, an oil cylinder barrel 4 is mounted on the outer side surface of the hollow piston 5, an oil cylinder guide sleeve 6 is mounted in a gap between the hollow piston 5 and the oil cylinder barrel 4, an oil duct sliding ring 7 is mounted on the outer side surface of the oil cylinder barrel 4, sliding ring bearings 8 are respectively arranged between two ends of the oil duct sliding ring 7 and the oil cylinder barrel 4, and a hydraulic oil interface 9 communicated with the inner side is formed in the oil duct sliding ring 7.
The number of the clamping jaws 3 is 3, and the clamping jaws are uniformly distributed on the inner side surface of the chuck inner sleeve 2 in the circumferential direction.
According to the structure, when the chuck is installed, the chuck 1 is used as a bearing and is arranged on the chuck inner sleeve 2; the chuck inner sleeve 2 adopts a built-in installation mode to install the clamping jaws 3 and is also installed in the chuck 1; the three clamping jaws 3 are uniformly arranged inside the chuck inner sleeve 2; the oil cylinder barrel 4 is connected and arranged outside the hollow piston 5; the hollow piston 5 is connected with the chuck inner sleeve 2 to play a role in pushing; the oil cylinder guide sleeve 6 is arranged between the hollow piston 5 and the oil cylinder barrel 4; the oil duct slip ring 7 is arranged outside the oil cylinder barrel 4; and a slip ring bearing 8 is arranged between the oil duct slip ring 7 and the oil cylinder barrel 4.
During the use, inject hydraulic oil into through the hydraulic oil interface 9 above the oil duct sliding ring 7 with hydraulic oil, promote hollow piston 5 through the oil pressure and drive chuck endotheca 2 fore-and-aft movement for install in chuck endotheca 2 play and promote the tight steel pipe action of closing of three jack catch 3, through installing in hollow piston 5, hydro-cylinder 4, oil duct sliding ring 7, hydro-cylinder 4 and the reasonable cooperation between the sliding ring bearing 8, thereby make the steel pipe when pressing from both sides tightly, can rotate the operation simultaneously.
All the above components are prior art, and those skilled in the art can use any model and existing design that can implement their corresponding functions.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
