Description
Technical Field
The invention relates to the technical field of hydraulic chucks, in particular to a hydraulic chuck with a compression spring reset function.
Background
The hydraulic chuck comprises a chuck and a chuck seat, the upper end of the chuck seat is rotatably connected with the middle of the chuck through a rotating shaft, a jacking mechanism is arranged below one end of the chuck, the upper end of the chuck seat is vertically provided with a tension spring between one end of the chuck and the upper end of the chuck, and the tension spring and the jacking mechanism are positioned on the same side of the rotating shaft. When the chuck does not work, the chuck is reset through the extension spring. The existing hydraulic chuck is reset by tensile force generated by an extension spring, and the situation that the tensile force is insufficient and the reset is slow or the reset cannot be realized can be caused by the reset of the extension spring, so that the structure of the hydraulic chuck needs to be optimized.
Disclosure of Invention
The invention aims to solve the technical problem of providing a hydraulic chuck for restoring a compression spring, wherein the compression spring and a jacking mechanism are respectively positioned at two sides of a rotating shaft, the compression spring is obliquely arranged, the compression spring generates elastic force to restore, the restoring speed is high, and the restoring performance is better.
The technical scheme adopted by the invention for solving the technical problems is as follows: the hydraulic chuck comprises a chuck body and a chuck base, wherein the upper end of the chuck base is rotatably connected with the middle of the chuck body through a rotating shaft, a jacking mechanism is arranged below one end of the chuck body at the upper end of the chuck base, and a compression spring is obliquely arranged between the upper end of the chuck base and the other end of the chuck body.
As a supplement to the technical scheme of the invention, the jacking mechanism comprises a piston cover and a piston, a chamber is arranged at the upper end of the chuck seat below one end of the chuck, an opening at the upper end of the chamber is sealed by the piston cover, a piston sliding up and down is arranged in the chamber, the upper end of the piston vertically penetrates through the piston cover, and an oil inlet and outlet passage connected with the bottom of the chamber is arranged in the chuck seat.
As a supplement to the technical solution of the present invention, a ring of sealing ring is arranged at the lower end of the piston.
As a supplement to the technical scheme of the invention, the piston cover is provided with a through hole for the piston to pass through, and a circle of sealing ring is arranged on the inner wall of the through hole.
Has the advantages that: the invention relates to a hydraulic chuck for resetting a compression spring.

Fig. 1 is a schematic structural view of the present invention.
The figure is as follows: 1. compression spring, 2, rotation axis, 3, chuck, 4, piston cover, 5, chamber, 6, oil inlet and outlet way, 7, piston, 8, chuck seat, 9 and sealing ring.
Detailed Description
The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
The embodiment of the invention relates to a hydraulic chuck with a compression spring reset function, which comprises a chuck 3 and a chuck seat 8, wherein the upper end of the chuck seat 8 is rotatably connected with the middle part of the chuck 3 through a rotating shaft 2, a jacking mechanism is arranged at the upper end of the chuck seat 8 and below one end of the chuck 3, and the compression spring 1 is obliquely arranged between the upper end of the chuck seat 8 and the other end of the chuck 3.
The hydraulic chuck before improvement comprises a chuck and a chuck seat, the upper end of the chuck seat is rotatably connected with the middle of the chuck through a rotating shaft, a jacking mechanism is arranged below one end of the chuck, which is positioned at the upper end of the chuck seat, an extension spring is vertically arranged between the upper end of the chuck seat and one end of the chuck, and the extension spring and the jacking mechanism are positioned at the same side of the rotating shaft. When the chuck is out of work, the chuck is reset through the extension spring, and the situation that the chuck is not enough to reset slowly or cannot be reset can be caused when the extension spring generates pulling force to reset.
The improved hydraulic chuck comprises a chuck 3 and a chuck seat 8, a compression spring 1 and a jacking mechanism are respectively positioned on two sides of a rotating shaft 2, the compression spring 1 is obliquely arranged, and the compression spring 1 generates elasticity to reset.
Compared with the improved hydraulic chuck, the hydraulic chuck before improvement has the advantages that firstly, the tension force generated by the spring is assumed to be consistent with the elastic force, and the force arm is larger after the change, so that the generated reset moment is larger; and secondly, assuming that the elastic coefficients of the springs are consistent, the force arm is larger after the change, namely the compression amount of the springs is larger than the stretching amount before the change when the chuck rotates at the same angle, and the generated force is larger. In conclusion, the reset performance is better after the change.
The jacking mechanism comprises a piston cover 4 and a piston 7, a chamber 5 is arranged below one end of the chuck 3 at the upper end of the chuck seat 8, an opening at the upper end of the chamber 5 is sealed by the piston cover 4, the chamber 5 is internally provided with the piston 7 which slides up and down, the upper end of the piston 7 vertically penetrates through the piston cover 4, and an oil inlet and outlet passage 6 connected with the bottom of the chamber 5 is arranged in the chuck seat 8. The oil inlet and outlet circuit 6 comprises an oil inlet circuit and an oil outlet circuit, the oil inlet circuit feeds oil into the cavity 5 to enable the piston 7 to ascend, the upper end of the piston 7 can prop against one end of the chuck 3 to ascend together, and the other end of the chuck 3 can be pressed downwards; the piston 7 is lowered by the oil exiting the oil outlet passage in the chamber 5.
And a circle of sealing ring 9 is arranged at the lower end of the piston 7, so that the sealing property is ensured.
The piston cover 4 is provided with a through hole for the piston 7 to pass through, and the inner wall of the through hole is provided with a circle of sealing ring 9 to ensure the sealing property.
