Description

Technical Field

[0001] The utility model relates to a double-arc fixture chuck tooling, belonging to the technical field of equipment detection. Background Art

[0002] During the detection of gas cylinders, a chuck is needed for clamping. In the common chuck structure, the jaws directly contact the gas cylinder, and the bottom of the gas cylinder is also likely to touch the surface of the chuck, causing scratches on the surface of the gas cylinder. Therefore, how to ensure that the surface of the gas cylinder is not scratched during the detection process is also a problem that needs to be solved by those skilled in the art. Content of the Utility Model

[0003] Aiming at the problems existing in the prior art, a double-arc fixture chuck tooling is provided, which includes a base and a chuck seat body installed on the base; the special feature is that the chuck seat body includes a chuck seat, jaws and a jaw driving mechanism; an installation hole for installing a support rod is provided at the center of the chuck seat, and both ends of the installation hole are counterbores; four jaw movement holes are arranged around the installation hole; the support end of the support rod includes a gas cylinder seat with an arc-shaped groove, the tail end of the support rod is set into a T-shaped structure, the gas cylinder seat is threadedly connected to the rod body of the support rod, and a spring is sleeved on the rod body of the support rod, and the spring is placed in the installation hole.

[0004] The advantages of the above technical solution are: through the elastic action of the spring, a buffer support is provided for the support of the bottom of the gas cylinder by the support rod, avoiding direct contact between the gas cylinder and the chuck during installation and forming a hard collision to cause damage.

[0005] On the basis of the above technical solution, the following improvements and refinements are made in this application:

[0006] Further, the jaw driving mechanism includes a driving disk, a gear ring is installed on the outer circumference of the driving disk, and the gear at the output end of the driving motor meshes with the gear ring; an installation hole is provided at the center of the driving disk, and four arc-shaped driving holes are arranged around the installation hole.

[0007] The beneficial effects of the above technical features in this application are: the driving motor drives the driving disk to rotate through gear transmission, and during the rotation of the driving disk, the jaws are driven to gather and disperse through the arc-shaped driving holes.

[0008] Further, a fixed support seat is arranged on the back of the chuck seat, and the fixed support seat is fixedly connected to the chuck seat; a shaft rod is provided at the center of the disk of the fixed support seat, and the driving disk is installed on the shaft rod; a long hole matching the jaw movement hole on the chuck seat is provided on the disk surface of the fixed support seat.

[0009] The beneficial effects of the above technical features in this application are as follows: The fixed support base and the chuck base are detachably installed. On the one hand, it is convenient to install components such as jaws on the chuck base. On the other hand, it also limits the components on the chuck base. At the same time, the shaft rod on the fixed support base is used to connect to the drive disk.

[0010] Further, the jaw includes a jaw clamping portion and a jaw drive rod. The end of the jaw clamping portion in contact with the gas cylinder is set to be arc-shaped, and both sides of the jaw clamping portion are flat; the jaw drive rod passes through the corresponding holes on the chuck base, the fixed support base, and the drive disk.

[0011] Further, a rubber pad is provided on the arc surface of the jaw clamping portion.

[0012] The beneficial effects of the above technical features in this application are as follows: The jaw clamping portion is set to have an arc-shaped cross-section to fit the structure of the gas cylinder. On the other hand, by installing a rubber pad, the damage to the gas cylinder is reduced.

[0013] In actual use of the double-arc fixture chuck tooling of the present utility model, the rotation of the drive disk drives the jaws to open and close, which can adapt to gas cylinders of different sizes. Through the support rod with an elastic structure in the center, the buffer padding of the bottom of the gas cylinder is realized, reducing the possibility of damage. Description of the Drawings
