[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The present application embodiment discloses a positioning tool for a CNC lathe. Figure 1 , including a processing table 1, fixed plates 2 are welded on both sides of the bottom of the processing table 1, and a plurality of through holes are equidistantly opened on the surface of the fixed plate 2. The fixed plate 2 is used to support the bottom of the processing table 1, and a limiting column 3 is welded on one side of the top of the processing table 1. One end of the workpiece can be placed against the limiting column 3, and support plates 5 are symmetrically provided on both sides of the back wall of the processing table 1. The top of the support plate 5 is an integrated structure to fix a limiting top plate 6, and the side wall of the workpiece is made to fit the inner wall of the support plate 5, so that the top of the workpiece can be limited by the limiting top plate 6.
[0020] like Figure 2 As shown, a reinforcement block 4 is symmetrically provided at the front end of the processing table 1, a rubber block 8 is provided inside the reinforcement block 4, a threaded rod 7 is threadedly connected at the center of the reinforcement block 4, one end of the threaded rod 7 is movably connected to the rubber block 8, and the other end of the threaded rod 7 extends to the outside of the reinforcement block 4 and is fixed with a rotating block 9. Rotating the rotating block 9 can drive the threaded rod 7 to move inside the reinforcement block 4, and then push the rubber block 8 to be fixed close to the outer wall of the workpiece.
[0021] Combination Figure 3 A support rod 12 is provided on one side of the rubber block 8, and a movable pressure plate 11 is slidably provided on the support rod 12. A positioning rod 10 for supporting the movable pressure plate 11 is fixed to one side of the top of the reinforcement block 4. The movable pressure plate 11 and the positioning rod 10 are slidably connected. The positioning rod 10 and the support rod 12 are used to position the movable pressure plate 11 to prevent the movable pressure plate 11 from deflecting.
[0022] A stop block 14 is fixed to the bottom of the movable pressure plate 11 at one end away from the positioning rod 10, and the stop block 14 can limit the upper part of the workpiece. A return spring 13 is sleeved on the outer wall of the support rod 12, and the return spring 13 is fixed to the inner wall of the movable pressure plate 11 at one end away from the processing table 1. The top ends of the positioning rod 10 and the support rod 12 are fixed with a limiting block 15, which provides supporting elasticity for the movable pressure plate 11 and is suitable for positioning workpieces of different thicknesses.
[0023] The implementation principle of a positioning tool for a CNC lathe in an embodiment of the present application is as follows: when in use, pull the two movable pressure plates 11 upwards, place one end of the workpiece to be processed on the processing table 1, and make one end of it close to the limiting column 3 for limiting, while making the rear end side wall of the workpiece close to the support plate 5, and limit the upper part of the workpiece through the limiting top plate 6, then release the movable pressure plate 11, due to the elasticity of the return spring 13, the movable pressure plate 11 will be pulled to slide downward outside the positioning rod 10 and the support rod 12, and the positioning rod 10 has a positioning function to prevent deviation. At this time, the movable pressure plate 11 can be pulled downward to push the stop block 14 to close to the upper part of the workpiece for positioning, and finally adjust the rotating block 9 to push the rubber block 8 close to the outer wall of the other side of the workpiece through the threaded rod 7 for fixing, thereby completing multi-point positioning, greatly enhancing the positioning effect of the workpiece and ensuring the stability of subsequent processing.
