[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A replaceable fixture for machining machine tool parts includes a U-shaped base 1. Horizontally arranged cylinders 2 are fixedly inserted into the inner left and right sides of the base 1 to drive movable blocks 3 to move. The opposite ends of the two cylinders 2 pass through the base 1. Two fixing rings 7 are fixedly sleeved on the cylinders 2 to support them. The outer walls of the two fixing rings 7 are fixedly connected to the movable blocks 3 and the outer walls of the base 1, respectively. Movable blocks 3 are fixedly connected to the opposite ends of the two cylinders 2 to drive clamping blocks 4 to move. A horizontally arranged first guide rod 6 is fixedly connected to the side of the movable block 3 away from the clamping blocks 4 to guide the movement of the movable block 3. The end of the first guide rod 6 away from the movable block 3 slides through the base 1.

[0024] In this embodiment, the movable block 3 is provided with a T-shaped groove on the side away from the cylinder 2. A T-shaped connecting block 5 is slidably inserted into the inner wall of the T-shaped groove to prevent the clamping block 4 from loosening. The end of the connecting block 5 away from the cylinder 2 passes through the T-shaped groove and is fixedly connected to the clamping block 4 for clamping the workpiece. A support block 14 is provided at the bottom of the T-shaped groove to support the connecting block 5. One end of the support block 14 is fixedly connected to the inner wall of the T-shaped groove. A vertically arranged positioning rod 9 is fixedly connected to the upper end of the support block 14 to cooperate with the positioning groove to position the connecting block 5. The lower end of the connecting block 5 is provided with a positioning groove corresponding to the positioning rod 9. The upper end of the positioning rod 9 slides into the positioning groove. The upper end of the positioning rod 9 is tapered to facilitate the insertion of the positioning rod 9 into the positioning groove.

[0025] In this embodiment, a sliding groove is provided on the inner wall of the T-shaped groove and on the side away from the clamping block 4. A slider 8 is slidably connected on the inner wall of the sliding groove to support the clamping block 1. A semi-circular clamping block 13 is fixedly connected on the side of the slider 8 facing the connecting block 5 to cooperate with the clamping groove to prevent the connecting block 5 from loosening. There are multiple clamping blocks 13 to improve the clamping effect. A clamping groove corresponding to the clamping block 13 is provided on the outer wall of the connecting block 5. The end of the clamping block 13 away from the slider 8 slides into the clamping groove.

[0026] In this embodiment, both the upper and lower ends of the slider 8 are fixedly connected to limit blocks 12, which are used to cooperate with the limit groove to limit the movement stroke of the slider 8. The inner side wall of the slide groove is provided with a limit groove corresponding to the limit block 12. The end of the limit block 12 away from the slider 8 slides into the limit groove. A plurality of horizontally arranged second guide rods 10 are slidably inserted on the side of the slider 8 away from the locking block 13, which are used to guide the movement of the slider 8. The end of the second guide rod 10 away from the locking block 13 is fixedly connected to the inner side wall of the slide groove. A spring 11 is slidably sleeved on the second guide rod 10, which is used to provide elastic support for the slider 8. The two ends of the spring 11 abut against the slider 8 and the inner side wall of the slide groove, respectively.

[0027] In this embodiment, cylinder 2 is first activated to drive movable block 3 to move linearly. Movable block 3 drives clamping block 4 to move, moving the two clamping blocks 4 in opposite directions and placing the workpiece between the two clamping blocks 4 to complete clamping. Clamping block 4 is detachably connected to movable block 3 through connecting block 5. Connecting block 5 is slidably embedded in T-shaped groove. If clamping block 4 needs to be replaced, the user pulls clamping block 4 upward, and connecting block 5 immediately disengages from T-shaped groove. In the locking structure between connecting block 5 and movable block 3, locking block 13 is provided with a certain amount of movement by spring 11 and slider 8 forming an elastic support system. When the user pulls clamping block 4 to raise connecting block 5, connecting block 5 (inner wall of the slot) contacts the semi-circular surface of locking block 13, pushing locking block 13 to move inward to the inside of the slot, achieving automatic unlocking. When connecting block 5 is reinserted into T-shaped groove, spring 11 pushes slider 8 to reset, causing locking block 13 to engage in the slot, forming a lock, effectively preventing clamping block 4 from accidentally loosening.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
