The utility model discloses a compression spring and climbing mechanism are located the both sides of rotation axis respectively, and compression spring is the slope and arranges, produces elasticity through compression spring and resets, and reset speed is fast, and the performance that resets is better.
Description
Technical Field
The utility model relates to a hydraulic pressure chuck technical field especially relates to a hydraulic pressure chuck that compression spring resets.
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 utility model aims to solve the technical problem that a hydraulic chuck that compression spring resets is provided, compression spring and climbing mechanism are located the both sides of rotation axis respectively, and compression spring is the slope and arranges, produces elasticity through compression spring and resets, and reset speed is fast, and the performance of resetting is better.
The utility model provides a technical scheme that its technical problem adopted is: 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 right technical scheme a supplement, climbing mechanism include piston cap and piston, the below that is located chuck one end on the chuck seat be provided with the cavity, the opening part of this cavity upper end seals through the piston cap, the cavity in install gliding piston from top to bottom, the upper end of this piston is vertical to be passed the piston cap, the chuck seat in be provided with the business turn over oil circuit that links to each other with the cavity bottom.
As right technical scheme a supplementary, the piston lower extreme arranged the round sealing washer.
As a supplement to the technical scheme of the utility model, the piston lid open and to have the through-hole that supplies the piston to pass, the inner wall of this through-hole is arranged with the round sealing washer.
Has the advantages that: the utility model relates to a hydraulic chuck that compression spring resets, compression spring and climbing mechanism are located the both sides of rotation axis respectively, and compression spring is the slope and arranges, produces elasticity through compression spring and resets, and it is fast to reset, and the performance that resets is better.
Drawings
Fig. 1 is a schematic structural diagram 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 present invention will be further described 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. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
The utility model discloses an embodiment relates to a compression spring's hydraulic chuck that resets, as shown in fig. 1, including chuck 3 and chuck seat 8, chuck seat 8 upper end rotate with chuck 3 middle part through rotation axis 2 and be connected, the below that this chuck seat 8 upper end is located 3 one ends of chuck is provided with climbing mechanism, the 3 other ends of chuck seat 8 upper end and chuck between the slope install compression spring 1.
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.
