Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, and in particular to a chuck with a double-sided double clamping unit. Background Technology

[0002] A chuck is a type of clamping equipment that clamps the workpiece to be processed by controlling the movement of the jaw mechanism. A drive mechanism is set inside the chuck, which drives the jaw mechanism. In the existing technology, chucks with auxiliary jaws generally have the jaws on both sides sharing the drive mechanism and the air distribution mechanism. The structures are interconnected, making installation and maintenance very inconvenient. Moreover, the jaws on both sides are linked structures, resulting in poor operability and making them unsuitable for high-precision clamping operations. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a chuck with two clamping units on both sides. The two clamping units are modularly configured, can operate independently, have stronger controllability, and are more convenient to install and maintain.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a chuck with double-sided double clamping units, characterized in that: it has clamping units, two clamping units are arranged on both sides of a rotating mechanism, the rotating mechanism can drive the clamping units to rotate, each clamping unit includes a housing, a claw mechanism, a drive mechanism and an air distribution mechanism, the drive mechanism can drive the claw mechanism to open and close, the air distribution mechanism includes an air distribution ring, the air distribution ring is provided with an air passage, the air passage is connected to the drive mechanism and the air inlet on the housing.

[0005] In the above technical solution, the clamping unit is provided with two sets of driving mechanisms, each of which can control two jaw mechanisms.

[0006] In the above technical solution, the driving mechanism is a driving cylinder and its transmission assembly installed in the clamping unit. The driving cylinder is connected to the air passage and drives the claw mechanism to open and close through the transmission assembly.

[0007] In the above technical solution, the transmission component includes a linkage ring, a bridge gear, and a rocker arm. The drive cylinder is connected to the linkage ring, and the linkage ring is connected to one end of the rocker arm via the bridge gear. The other end of the rocker arm is connected to the chuck mechanism.

[0008] In the above technical solution, the jaw seat of the jaw mechanism is mounted on the opening and closing slider, and the opening and closing slider can reciprocate along the opening and closing track under the drive of the driving mechanism.

[0009] In the above technical solution, the drive cylinders of the two clamping units are staggered.

[0010] In the above technical solution, the rotating mechanism is a rotating gear disposed between two clamping units and a rotating motor on the side of the rotating gear.

[0011] In summary, the advantages of the technical solution of this utility model compared with traditional technical means are as follows: the chuck of this utility model adopts a modular design, with two clamping units modularly set, fully functional with double-sided auxiliary claws, a single chuck can clamp steel pipes, making it more controllable and easier to install and maintain.

Detailed Implementation

[0020] Based on the preferred embodiments of this utility model, and through the following description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.

[0021] The present invention will be further described with reference to the following figures:

[0022] like Figures 1-6 As shown, a chuck with two clamping units on both sides has two clamping units 100. The two clamping units 100 are arranged on both sides of a rotating mechanism 200. The rotating mechanism 200 can drive the clamping units 100 to rotate. Each clamping unit 100 includes a housing 300, a jaw mechanism 400, a drive mechanism 500, and an air distribution mechanism 600. The drive mechanism 500 can drive the jaw mechanism 400 to open and close. The air distribution mechanism 600 includes an air distribution ring 610. The air distribution ring 610 is provided with an air passage 611. The air passage 611 is connected to the air inlet 310 on the drive mechanism 500 and the housing 300.

[0023] like Figure 5 As shown, the clamping unit 100 is provided with two sets of drive mechanisms 500, each set of drive mechanisms 500 can control two jaw mechanisms 400.

[0024] The driving mechanism 500 is a driving cylinder 510 and its transmission assembly 520 disposed in the clamping unit 100. The driving cylinder 510 is connected to the air passage 611 and drives the claw mechanism 400 to open and close through the transmission assembly 520.
