Technical Field
[0001] This utility model belongs to the field of fixture and tooling technology, and in particular relates to a clamping structure for machining linear guide rails. Background Technology
[0002] During the machining of linear guides, the clamping structure must ensure machining accuracy, stability, and efficiency.
[0003] In existing linear guide rail machining and clamping, the end of the guide rail is clamped and fixed by driving the clamping plate with a long stud. Over time, the stud is prone to deformation, affecting the movement of the symmetrical clamping plate and the clamping accuracy. At the same time, the clamping method is relatively simple. Utility Model Content
[0004] The technical problem to be solved by this utility model is to improve the end clamping during guide rail processing, improve the clamping flexibility during guide rail processing, make the structure compact, and avoid deformation of the track structure.
[0005] To solve the above technical problems, the present invention adopts the following technical solution: a clamping structure for linear guide rail processing, comprising a base plate and a baffle plate, the baffle plate being fixedly connected to one side of the base plate, a sliding groove being formed at the center of the base plate, and further comprising a reference plate, a push plate, a limiting component, and a pushing support component. The reference plate is fixedly connected to the middle of the upper part of the base plate and close to the baffle plate, the two ends of the reference plate having limiting grooves, the limiting components being movably connected to the limiting grooves at both ends of the reference plate, the limiting components being symmetrically distributed left and right, and rotating and adjusting against the upper wall of the base plate with the two ends of the reference plate as the center. The push plate is slidably disposed in the sliding groove through the pushing support component, the pushing support component being fixedly connected to the bottom wall of the base plate.
[0006] Furthermore, the limiting assembly includes a connecting block, a cylinder, a stud, and a clamping plate. The stud is rotatably connected to the limiting groove, one end of the connecting block is rotatably connected to the limiting groove via the stud, the cylinder is fixedly connected to the other end of the connecting block, and the clamping plate is fixedly connected to the telescopic end of the cylinder away from the connecting block.
[0007] Furthermore, the upper end of the stud extends through the reference plate to the upper part of the reference plate, and a locking nut is movably connected to the outer wall of the upper end of the stud for fixing the position of the cylinder steering adjustment.
[0008] Furthermore, the pushing support assembly includes a moving frame, a rotary motor, a screw, and a moving plate. The moving frame is fixedly connected to the bottom wall of the base plate and located directly below the slide groove. The rotary motor is installed on the outer wall of one end of the moving frame. One end of the screw is fixedly connected to the output end of the rotary motor, and the other end of the screw is rotatably connected to the inner wall of the moving frame. The moving plate is threadedly connected to the outer wall of the screw and slides against the relative inner wall of the moving frame.
[0009] Furthermore, the push plate is fixedly connected to the upper part of the movable plate, and its bottom wall is slidably attached to the upper wall of the bottom plate.
[0010] Furthermore, the base plate has through holes at its corners, and a support tube is fixedly connected to the bottom wall of the base plate, with the center of the support tube coaxial with the through hole.
[0011] After adopting the above structure, the beneficial effects of this utility model are as follows: For the end clamping during guide rail processing, the side wall of the reference plate is used as the reference. The guide rail side wall is pushed to move by the vertical movement of the push plate so that it fits with the reference plate. At the same time, the end limiting components retract to achieve clamping of guide rails of different lengths at both ends.
[0012] The limiting components rotate at both ends of the reference plate. When they rotate to be perpendicular to the reference plate, they work with the reference plate to clamp the end of the track over a shorter distance. At the same time, the push plate moves along the slide groove to support the side wall of the clamping track at different positions. Attached Figure Description

Detailed Implementation
[0019] like Figure 1-4As shown, a clamping structure for machining linear guides includes a base plate 1 and a baffle 2. The baffle 2 is fixedly connected to one side of the base plate 1. A sliding groove 3 is formed at the center of the base plate 1. The structure also includes a reference plate 4, a push plate 5, a limiting assembly 6, and a pushing support assembly 7. The reference plate 4 is fixedly connected to the upper middle part of the base plate 1, near the baffle 2. Limiting grooves 8 are formed at both ends of the reference plate 4. The limiting assembly 6 is movably connected within the limiting grooves 8 at both ends of the reference plate 4. The limiting assembly 6 is symmetrically distributed left and right and rotates to adjust against the upper wall of the base plate 1 with the two ends of the reference plate 4 as the center. The push plate 5... The push support assembly 7 is slidably disposed in the slide groove 3. The push support assembly 7 is fixedly connected to the bottom wall of the base plate 1. A through hole 18 is opened at the corner of the base plate 1. A support tube 19 is fixedly connected to the bottom wall of the base plate 1. The center of the support tube 19 is coaxially arranged with the through hole 18. The longer guide rail is placed along the length of the base plate 1. The push support assembly 7 drives the push plate 5 to move towards the reference plate 4. At the same time, the push plate 5 contacts the bottom of the guide rail side wall, pushing the guide rail to fit against the side wall of the reference plate 4. The symmetrical limit assemblies 6 at both ends are parallel to the reference plate 4. The extension and retraction adjustment of the limit assemblies 6 clamps the end of the guide rail.
[0020] like Figure 1-3 As shown, in order to achieve clamping when processing guide rails of different lengths, the limiting component 6 includes a connecting block 9, a cylinder 10, a stud 11, and a clamping plate 12. The stud 11 is rotatably connected to the limiting groove 8. One end of the connecting block 9 is rotatably connected to the limiting groove 8 through the stud 11. The cylinder 10 is fixedly connected to the other end of the connecting block 9. The clamping plate 12 is fixedly connected to the telescopic end of the cylinder 10 away from the connecting block 9. The connecting block 9 is connected through the stud 11 and rotates in the limiting groove 8, which simultaneously drives the cylinder 10 and the clamping plate 12 to rotate synchronously. At the same time, the bottom wall of the clamping plate 12 slides against the upper wall of the base plate 1. The upper end of the stud 11 extends through the reference plate 4 to the upper part of the reference plate 4. A locking nut 13 is movably connected to the outer wall of the upper end of the stud 11 for fixing the position of the cylinder 10 for steering adjustment. When the position of the cylinder 10 is fixed, the locking nut 13 is tightened to fix the position of the cylinder 10.
[0021] like Figure 1-4As shown, to assist in positioning the guide rail during clamping, the push support assembly 7 includes a moving frame 14, a rotary motor 15, a screw 16, and a moving plate 17. The moving frame 14 is fixedly connected to the bottom wall of the base plate 1 and located directly below the slide groove 3. The rotary motor 15 is installed on the outer wall of one end of the moving frame 14. One end of the screw 16 is fixedly connected to the output end of the rotary motor 15, and the other end of the screw 16 is rotatably connected to the inner wall of the moving frame 14. The moving plate 17 is threadedly connected to the outer wall of the screw 16 and slides against the relative inner wall of the moving frame 14. The push plate 5 is fixedly connected to the upper part of the moving plate 17, and its bottom wall slides against the upper wall of the base plate 1. The rotary motor 15 is driven to rotate, and the screw 16 rotates inside the moving frame 14, pushing the moving plate 17 to move and adjust against the inner wall of the moving frame 14, while simultaneously pushing the push plate 5 to move, thereby realizing the pushing or limiting of the guide rail.
[0022] In actual use, the operator places the guide rail on the base plate 1. In the initial state, the symmetrical limiting component 6 is attached to the baffle 2 and keeps in the same straight line as the reference plate 4. The telescopic end of the cylinder 10 is in the extended state, and the push plate 5 is far away from the reference plate 4.
[0023] When fixing a long guide rail, place the long guide rail on the base plate 1 along the length of the base plate 1, drive the rotary motor 15 to rotate in the forward direction, the screw 16 rotates in the moving frame 14, and push the moving plate 17 to move towards the reference plate 4 in contact with the moving frame 14, drive the push plate 5 to push the bottom of the guide rail side wall to fit with the reference plate 4, and drive the cylinder 10 to retract, so that the symmetrical clamping plate 12 contacts the end of the guide rail, thereby achieving the clamping and fixing of the guide rail;
[0024] When the shorter guide rail is fixed, the locking nut 13 is in a loose state. Rotate the cylinder 10, and the connecting block 9 is connected by the stud 11. It rotates in the limiting groove 8, and the bottom wall of the clamping plate 12 slides against the upper wall of the base plate 1. When the cylinder 10 is perpendicular to the reference plate 4, tighten the locking nut 13 to fix the position of the cylinder 10. Drive the rotary motor 15 to rotate and adjust the push plate 5 to the middle position of the slide groove 3 to provide a support reference for the side wall of the guide rail. Place the vertical reference plate 4 of the guide rail on the base plate 1 and drive the cylinder 10 to retract, thereby clamping both ends of the shorter guide rail.
