Description

Technical Field

[0001] The utility model relates to the technical field of chuck jaws, in particular to a double-layer jaw. Background Art

[0002] Chuck jaws are mechanical components used to hold and position a workpiece on machining equipment. They are typically evenly spaced along the chuck and work by moving toward or away from the center. The jaws are the components of the chuck that secure the workpiece to the chuck, ensuring stability and accuracy during machining.

The first clamping jaw seat 2 and the second clamping jaw seat 3 are symmetrically installed on the chuck unit 01. The chuck unit 01 includes a mounting seat 1, and a mounting groove 11 is opened on the mounting seat 1. The first clamping jaw seat 2 and the second clamping jaw seat 3 are symmetrically installed at the mounting groove 11. The first clamping jaw seat 2 and the second clamping jaw seat 3 can clamp pipe fittings and profiles more firmly.

[0024] Among them, a first mounting portion 21 is provided on the top of the side wall of the first claw seat 2 facing the other side of the first claw seat 2, and a second mounting portion 22 is provided below the first mounting portion 21. A first limit block 23 is provided at the bottom of the first claw seat 2, and the first limit block 23 can be inserted into the mounting groove 11. A first mounting hole 24 is vertically provided on the first claw seat 2, and a second fixing component 7 is installed at the first mounting hole 24. The first limit block 23 facilitates the first claw seat 2 to be firmly installed on the mounting seat 1.

[0025] In addition, a first clamping block 5 is installed on the first mounting portion 21, and a second clamping block 6 is installed on the second mounting portion 22. Mounting holes are provided on the first clamping block 5 and the second clamping block 6, and first fixing components 4 are installed at the mounting holes of the first clamping block 5 and the second clamping block 6. The first fixing component 4 facilitates the installation of the first clamping block 5 and the second clamping block 6 on the first claw seat 2.

[0026] At the same time, a plurality of first tooth blocks 51 are evenly distributed on the side wall of the first clamping block 5 facing the other side of the first claw seat 2, and a plurality of second tooth blocks 61 are evenly distributed on the side wall of the second clamping block 6 facing the other side of the first claw seat 2. The first tooth blocks 51 and the second tooth blocks 61 make the clamping surfaces of the first clamping block 5 and the second clamping block 6 toothed, thereby increasing the friction force and making the clamping more stable.

[0027] In addition, a third mounting portion 31 is provided on the top of the side wall of the second claw seat 3 facing the other side of the second claw seat 3, and a fourth mounting portion 32 is provided below the third mounting portion 31.

[0030] Moreover, when the first clamping block 5, the second clamping block 6, and the third clamping block 8 are all detachable, during installation, it is only necessary to align the mounting holes on each clamping block with the bolt holes on the first clamping claw seat 2 and the second clamping claw seat 3, and then install the first fixing component 4, so that the first clamping block 5, the second clamping block 6, and the third clamping block 8 can be fixed.

[0031] In addition, the first clamping block 5, the second clamping block 6 and the third clamping block 8 are all at different horizontal heights, thereby realizing double-layer clamping, and the first mounting portion 21 of the first clamping claw seat 2 is higher than the second mounting portion 22 by a certain distance, and the first clamping block 5, the second clamping block 6 and the first clamping claw seat 2 are designed to be separated, which is convenient for adjusting the bell mouth.

[0032] Moreover, the first clamping block 5, the second clamping block 6 and the third clamping block 8 can be replaced with different sizes.

[0033] The first reinforcement part 25 and the second reinforcement part 35 are easily supported by the first clamping block 5 and the third clamping block 8 installed below, thereby dispersing the pressure of certain clamping blocks, increasing the flange protection, and reducing the risk of screw breakage when pulling materials.

[0034] In addition, flange protection is added to the top of the jaw seat to reduce the risk of screw breakage when pulling materials.

[0035] In the utility model, the pipe material and the profile are clamped by the provided claw unit 02, and the clamping is performed by the provided first clamping block 5, the second clamping block 6, and the third clamping block 8. In addition, the provided first tooth block 51, the second tooth block 61, and the third tooth block 81 make the clamping surface of the clamping block tooth-shaped, thereby enhancing the friction force and making the clamping more stable. Moreover, the upper layer of the clamping claw seat is higher than the lower layer by a certain distance, and each clamping block and the clamping claw seat are designed to be separated, which is convenient for adjusting the bell mouth, thereby improving the stability and reliability during clamping and preventing slipping.
