[0035] The utility model proposes a U-shaped locking chuck locking processing tooling for use in lathe processing technology. The utility model does not limit the type of U-shaped locking chuck required for processing, but the lathe chuck 1, T-shaped block 2, slide block 3, claw 4 and concentric clamping block 5 structure are particularly suitable for using a lathe to process eccentric holes on a square part in a side view.

[0036] In general, the U-shaped locking chuck locking tooling proposed in the present invention mainly includes: a lathe chuck 1, a T-shaped block 2, a slide block 3, a claw 4 and a concentric clamping block 5, among which, it can be seen Figure 1 , which shows the arrangement relationship of the lathe chuck 1, T-block 2, slide block 3, claw 4 and concentric clamping block 5.

[0037] When the U-shaped locking chuck locking processing tooling proposed by the utility model is used, the claw 4 is connected to the slider 3, the position of the claw 4 on the T-shaped movable groove 21 is adjusted to complete the concentric clamping block 5, the slider 3 is limited by tightening the locking screw 42, the U-shaped locking chuck to be processed is placed in the clamping square groove 53, and the U-shaped locking chuck to be processed is limited by tapping the T-shaped block 2 along the claw slot 11, and the concentricity of the concentric clamping block 5 and the outer contour of the lathe chuck 1 is detected by using a punch table. The concentric clamping block 5 and the lathe chuck 1 are adjusted to be concentric by tapping the T-shaped block 2, and the lathe tailstock is controlled to move to drive the rotating head to open a hole in the middle of the top of the U-shaped locking chuck.

[0038] One end of the lathe chuck 1 is provided with three claw slots 11 at equal intervals for easy loosening and fixing.

[0039] The above-mentioned T-shaped block 2 is clamped in the claw groove 11, and a T-shaped movable groove 21 is opened in the middle of the top of the T-shaped block 2, and a slider 3 is arranged in the T-shaped movable groove 21 for transition matching, and a threaded connecting hole 32 is opened on the top of the slider 3. The top of the T-shaped block 2 is located on the left and right sides of the T-shaped movable groove 21 and triangular tooth grooves 31 are arranged. A claw 4 is arranged on the top of the slider 3, and a locking screw 42 is passed through the side of the center of the claw 4 away from the central axis of the lathe chuck 1. The bottom of the locking screw 42 passes through the claw 4 and the slider 3 in turn and is abutted against the bottom of the T-shaped movable groove 21. The opening and closing of the concentric clamping block 5 is controlled by controlling the movement of the claw 4. Triangular tooth blocks 41 are symmetrically arranged on the left and right sides of the bottom end of the claw 4, and the triangular tooth blocks 41 are meshed with the triangular tooth groove 31 to prevent the vibration of the lathe chuck 1 during rotation during processing from causing the position of the claw 4 to change, resulting in weakening of the clamping force of the clamped workpiece.

[0040] The above-mentioned concentric clamping block 5 is disc-shaped to reduce the vibration generated when the parts are clamped. The concentric clamping block 5 is arranged on the side of the clamping jaw 4 away from the lathe chuck 1 by welding. A Y-shaped groove 51 is opened in the middle of the concentric clamping block 5. The Y-shaped groove 51 divides the concentric clamping block 5 into three equal parts. Each part of the concentric clamping block 5 is connected to the clamping jaw 4 by welding. A processing hole clearance groove 52 is opened in the middle of the concentric clamping block 5. The processing hole clearance groove 52 is communicated with the Y-shaped groove 51 on all sides. A clamping square groove 53 is opened on the side of the concentric clamping block 5 away from the lathe chuck 1. The clamping square groove 53 is respectively communicated with the processing hole clearance groove 52 and the Y-shaped groove 51. Corner protection holes 54 are opened around the clamping square groove 53. The corner protection holes 54 prevent the corners of the U-shaped locking chuck to be processed from colliding and forming gaps during clamping.
