Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bushing cutting, and particularly relates to a fixture for bushing cutting. Background Art
[0002] A bushing is a die accessory that is used in conjunction with a guide pillar to play a guiding role. Generally, the clearance fit is very small. It is generally used in dies or some machinery to ensure the accuracy of movement. At present, when machining a stepped bushing, a left-right symmetrical structure is machined, and then it is cut in half by a cutting machine to form two bushings with the same structure, thereby simplifying the machining steps and saving machining costs. During the cutting process, a limiting plate needs to be placed in the middle of the fixture. When the movable fixture touches the limiting plate, the fixture just clamps the bushing to avoid excessive extrusion. However, the width of the limiting plate is fixed, and different-width limiting plates need to be replaced when cutting bushings with different diameters. Summary of the Invention
[0003] In view of this, the purpose of the utility model is to overcome the deficiencies in the prior art and provide a fixture for bushing cutting.

A fixed clamping block 2 is installed at the guide rail 1 on the right side of the movable clamping block 3. A screw rod 4 screwed to the movable clamping block 3 is horizontally and rotatably arranged in the guide rail 1. A horizontally arranged and adjustable limiting component is provided at the guide groove at the upper end of the guide rail 1. The limiting component includes a stabilizing block 6 connected to the left end of the fixed clamping block 2 and fitting to the guide groove, and an adjusting block 7 that is arranged on the stabilizing block 6 to be adjustable left and right and fits to the guide groove.
[0005] Further, on the front and rear sides of the upper end of the adjusting block 7, a runway-shaped counterbore 7.1 is horizontally opened. The adjusting block 7 is locked to the stabilizing block 6 through a locking bolt passing through the counterbore 7.1. An avoidance groove 7.3 is horizontally opened in the middle of the upper end of the adjusting block 7.
[0006] Further, on the front and rear sides of the left end of the stabilizing block 6, baffles 6.1 are horizontally arranged. A sliding groove 7.2 for the baffles 6.1 to slide fit is horizontally opened at the bottom of the adjusting block 7.
[0007] Further, a round hole for the screw rod 4 to pass through is opened at the lower end of the fixed clamping block 2.
[0008] Further, a crank handle 5 is arranged at the end of the screw rod 4.
[0009] Further, an elastic telescopic tube 8 sleeved outside the screw rod 4 is connected between the fixed clamping block 2 and the movable clamping block 3.

[0016] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.
[0017] Refer to Figures 1 to 5, the present utility model provides a fixture for guide bushing cutting, which includes a guide rail 1 installed on a cutting machine. A movable clamping block 3 is slidably fitted to move left and right at the guide rail 1. A fixed clamping block 2 is installed at the guide rail 1 on the right side of the movable clamping block 3. Slots for avoidance are respectively opened in the middle of the upper ends of the movable clamping block and the fixed clamping block. A screw rod 4 screwed to the movable clamping block 3 is horizontally and rotatably arranged in the guide rail 1. A crank handle 5 is arranged at the end of the screw rod 4. The crank handle is simple to operate, has good flexibility and reliability. A horizontally arranged limit component that can be adjusted left and right is provided at the guide groove at the upper end of the guide rail 1. The limit component includes a stabilizing block 6 connected to the left end of the fixed clamping block 2 and fitting to the guide groove, and an adjusting block 7 that can be adjusted left and right and fits to the guide groove is arranged on the stabilizing block 6. After adjusting the adjusting block left and right, place the guide bushing on the guide rail and the limit component. By rotating the screw rod, the movable clamping block moves rightward. When the movable clamping block contacts the adjusting block, the movable clamping block and the fixed clamping block just clamp the guide bushing to avoid excessive extrusion of the guide bushing. Cut the guide bushing in half to form two identical guide bushings. One can generate two in the early processing. After completing the cutting, reverse the screw rod and the movable clamping block moves leftward to reset.
[0018] Runway-shaped counterbores 7.1 are horizontally opened on the front and rear sides of the upper end of the adjusting block 7. The counterbores are provided to hide the locking bolts. The adjusting block 7 is locked to the stabilizing block 6 by the locking bolts passing through the counterbores 7.1. An avoidance groove 7.3 is horizontally opened in the middle of the upper end of the adjusting block 7. Loosen the locking bolts, adjust the left and right position of the adjusting block to adapt to guide bushings of different diameters, and tighten the locking bolts to lock the adjusting block. The avoidance groove is used to avoid the cutting blade cutting downward.
[0019] Baffles 6.1 are horizontally arranged on the front and rear sides of the left end of the stabilizing block 6. A chute 7.2 for the baffle 6.1 to slide fit is horizontally opened at the bottom of the adjusting block 7. The baffle can block the metal chips falling from the counterbores. Try to keep the metal chips on the stabilizing block and the adjusting block.
[0020] A round hole for the screw rod 4 to pass through is opened at the lower end of the fixed clamping block 2. The screw rod is screwed to the movable clamping block. The screw rod passes through the round hole of the fixed clamping block. When the screw rod rotates, the movable clamping block will move left and right to clamp the guide bushing.
[0021] Refer to Figure 2 , Figure 5 , an elastic telescopic tube 8 sleeved outside the screw rod 4 is connected between the fixed clamping block 2 and the movable clamping block 3. The elastic telescopic tube is provided to prevent metal chips from falling onto the screw rod, thus causing damage, and the elastic telescopic tube will not affect the movement of the movable clamping block.
[0022] The fixture for guide bushing cutting of the present utility model: can adjust the adjusting block left and right, so that the limit component composed of the adjusting block and the stabilizing block can adapt to guide bushings of different diameters.
