Abstract
Description
Technical Field
[0001] The utility model relates to a clamping component, in particular to a hydraulically adjustable six-claw chuck. Background Art
[0002] The processing accuracy of thin-walled parts, ferrules, and thin-walled pipes is also increasing. The processing accuracy requirements of such parts are high and difficult to clamp. It is difficult to ensure the processing accuracy requirements by using traditional three-jaw chucks. Due to the weak structural strength of the product, conventional three-jaw clamping will cause product deformation, and the deformation will rebound after loosening, and the precise size requirements of the product after processing cannot be achieved. Therefore, a six-jaw chuck with soft jaws is required for clamping, so the structure of the chuck jaws needs to be adjusted to meet the processing requirements of the product;
[0003] In the prior art: CN202321466555.6 Six-jaw chuck clamping and positioning tooling, the utility model discloses a six-jaw chuck clamping and positioning tooling, including a chuck body, six groups of jaws are circumferentially arranged on the chuck body, a support plate is arranged in the area surrounded by the six groups of jaws, a plurality of support columns of equal height are arranged on the support plate, an airtight detection hole is opened on the end face of each of the support columns, and an air path channel connecting the airtight detection hole is opened in the support plate and the chuck body.
[0004] Although the prior art uses a six-jaw chuck to clamp parts to prevent deformation of the parts, and at the same time provides an airtightness detection function and an anti-misalignment pin to facilitate the installation of parts and detect whether the parts are placed in place, thereby improving processing efficiency, the six-jaw chuck in the prior art has problems with bottom positioning and insufficient support strength, which affects the subsequent processing of the workpiece assembled on the six-jaw chuck. Utility Model Content
[0005] In order to overcome the deficiencies of the prior art, the utility model provides a hydraulically adjustable six-jaw chuck.
[0006] The utility model is implemented by the following technical scheme: a hydraulically adjustable six-jaw chuck, comprising a chuck base, a mounting circular hole is arranged on the chuck base, a hydraulic control component is arranged at the bottom of the mounting circular hole, an adjustment module is arranged on the chuck base, the adjustment module is arranged around the mounting circular hole, the adjustment module is an adjustment claw, the adjustment claw is distributed on the outer surface of the chuck base, a positioning hole is arranged on the adjustment claw, a locking pin is arranged in the positioning hole, and a top cover is arranged on the top of the adjustment claw.
[0007] The hydraulic control component is a hydraulic pull rod, an assembly head is arranged on the hydraulic pull rod, a positioning groove is arranged on the assembly head, and the assembly head and the hydraulic device are connected to each other.
[0008] The top cover is a disc-mounted structure, the top cover covers the outside of the adjustment claw, and an assembly hole is arranged in the middle of the top cover.
[0009] The assembly hole in the middle of the top cover and the assembly circular hole on the chuck base are interconnected, and an assembly boss is arranged inside the top cover.
[0010] The chuck base is provided with a bottom assembly hole, the top of the hydraulic pull rod is provided with a pull rod platform, and the pull rod platform is assembled in the bottom assembly hole.
[0011] Compared with the prior art, the utility model can utilize the adjustment claws arranged on the chuck base to grip the parts when in use, so that the parts can be gripped in all directions from multiple angles, which can meet the needs of subsequent gripping and processing of the parts. At the same time, a hydraulic pull rod for bottom support is provided at the bottom of the six-jaw chuck. The hydraulic pull rod can be used to control the movement of the hydraulic pull rod by relying on the hydraulic equipment, which can provide support to the bottom of the parts and allow the bottom of the six-jaw chuck to provide good supporting force.
