[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4The utility model provides a technical solution: a fixture for CNC machining, including a mounting block 1, a through slot 12 is opened in the mounting block 1, a workpiece 11 is placed in the through slot 12, a plurality of driving components and a plurality of auxiliary components are installed on one side of the mounting block 1, a clamping component is installed at the output end of the driving component, a push rod 3 is installed at the output end of the driving component, a nut 6 is installed between the push rod 3 and the clamping component, the auxiliary component includes a plurality of auxiliary clamping blocks 9, the auxiliary clamping blocks 9 are slidably connected to the mounting block 1, and the auxiliary clamping blocks 9 correspond to the clamping components.

[0022] In this embodiment, the driving assembly is a plurality of electric cylinders 2, the output end of the electric cylinder 2 is fixedly connected to the push rod 3, the clamping assembly includes a chuck 4, a connecting rod 5 is fixed to one side of the chuck 4, the connecting rod 5 and the push rod 3 are both threadedly matched with the nut 6, a buffer pad 13 is fixed to the side of the chuck 4 close to the workpiece 11, an inclined rod 14 is installed between the chuck 4 and the connecting rod 5, and the chuck 4, the connecting rod 5, and the inclined rod 14 form a triangular structure.

[0023] Specifically, when the chuck 4 needs to be replaced, the nut 6 is rotated so that the nut 6 is completely rotated onto the push rod 3. At this time, the connecting rod 5 loses the connection with the push rod 3, and the connecting rod 5 and the chuck 4 can be directly removed, thereby facilitating the replacement of the chuck 4.

[0024] When clamping the workpiece 11, the electric cylinder 2 is started, so that the electric cylinder 2 pushes the connecting rod 5 through the push rod 3, thereby pushing the chucks 4 to approach each other, so that the workpiece 11 can be clamped and fixed.

[0025] Elastic rods 7 are fixed on two connecting rods 5, one end of which is located on one side of the auxiliary clamping block 9. A groove 8 is opened in the mounting block 1, and the groove 8 is slidably connected to the auxiliary clamping block 9. A spring 10 is fixed between the auxiliary clamping block 9 and the groove wall of the groove 8.

[0026] Specifically, when the workpiece 11 needs to be clamped, the movement of the connecting rod 5 drives the elastic rod 7 to move, so that the elastic rod 7 no longer limits the auxiliary clamping block 9, so that the auxiliary clamping block 9 is pushed by the spring 10 to position the workpiece 11.

[0027] Specifically, when clamping a workpiece 11 that does not need to be inserted into the through groove 12, place the workpiece 11 between multiple chucks 4, and then manually move the elastic rod 7 so that the elastic rod 7 no longer limits the auxiliary clamp 9, so that the auxiliary clamp 9 is pushed by the spring 10 to position the workpiece 11, and then start the electric cylinder 2 to fix the workpiece 11.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
