Description

Technical Field

[0001] The utility model relates to the technical field of cutting processing, in particular to a cutting processing fixture. Background Art

[0002] In mechanical processing, it is often necessary to cut the workpiece. In order to ensure the stability of the tool during the cutting process, the workers usually use a cutting fixture to fix the workpiece to be processed. The existing cutting fixture usually consists of a base and a clamping mechanism.

[0003] For example: The utility model with application number 202020107036.0 discloses a fixture for cutting processing, specifically including a mounting frame, two threaded holes are symmetrically arranged at both ends of the mounting frame, and threaded rods are threadedly connected in the two threaded holes, a turn handle is fixedly connected to the end of the threaded rod away from the mounting frame, and an adapter ring is rotatably connected to the end of the threaded rod away from the turn handle. The utility model uses a first clamping plate and a second clamping plate arranged in a curved shape to clamp and fix the cutting workpiece, which can be applied not only to the clamping and fixing of square workpieces, but also to the clamping and fixing of circular workpieces, and the clamping effect is firm. When the convex rod is clamped in the groove, a mutual limiting effect is formed between the first clamping plate and the second clamping plate, and the limiting effect of the mounting frame on the two is cooperated, thereby enhancing the stability of the first clamping plate and the second clamping plate when clamping and fixing the workpiece, and preventing the workpiece from slipping off the fixture due to vibration during the cutting process.

[0004] However, with regard to the current traditional cutting processing fixtures, after the workpiece is cut, the staff is usually required to remove the cut workpiece first, and replace and fix the new workpiece before cutting. This means that in the process of cutting a large number of workpieces, the staff needs to frequently replace and fix the new workpiece, which is a cumbersome operation and increases the labor intensity of the staff. Utility Model Content

[0005] In view of this, the utility model provides a cutting processing fixture, which has an auxiliary frame that can automatically fix the workpiece during the cutting process and automatically fix the workpiece during the replacement process. After the cutting is completed, the driving motor is started, and the auxiliary frame clamping the cut workpiece is rotated out of the processing area through a series of transmissions, and the auxiliary frame clamping the workpiece to be cut is rotated to the processing area. In the process of the auxiliary frame clamping the workpiece to be cut being transferred to the processing area, the clamping gear is meshed with the clamping rack, and the clamping rack drives the clamping gear to rotate, and the control screw is driven to rotate by the rotation of the clamping gear. With the rotation of the control screw, the connecting sleeve drives the connecting frame to move upward. In the process of the connecting frame moving upward, under the action of the auxiliary connecting rod, the sliding sleeve is caused to slide inward along the connecting frame. In the process of the sliding of the sliding sleeve, the driving connecting rod drives the driving slider to slide. With the sliding of the driving slider, the clamping frame will automatically close to clamp and fix the workpiece to be cut.
