Description

Technical Field

[0001] This utility model relates to the field of guide rail drilling fixture technology, specifically a guide rail drilling fixture device. Background Technology

[0002] A guide rail is a groove or ridge made of metal or other materials used to support, fix, and guide moving devices or equipment and reduce friction during their movement. Guide rails are widely used in industrial production, elevators, pulleys and other mechatronic systems, and are an important component of guiding devices. When drilling holes in a guide rail, a clamping device is required to prevent it from moving or shifting during the drilling process.

[0003] Current guide rail drilling fixtures have significant design shortcomings, particularly lacking effective support for the guide rail during the drilling process. This deficiency is readily apparent in practical operation. When the drill bit applies the necessary drilling pressure to the guide rail, the guide rail often experiences undue deformation or displacement due to the fixture's inability to provide sufficient support. This instability not only severely affects the drilling accuracy and consistency but also leads to excessive stress and potential damage to the guide rail material. Over time, this will not only reduce the guide rail's service life but may also threaten the stability and safety of the entire system. Therefore, we propose a guide rail drilling fixture device. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for drilling guide rails, in order to solve the obvious deficiencies in the design of current clamping devices for drilling guide rails mentioned in the background art, especially the lack of effective support function for the guide rail during the drilling process. This defect is fully exposed in actual operation. When the drill bit applies the necessary drilling pressure to the guide rail, the guide rail is prone to undue deformation or displacement because the clamp fails to provide sufficient support force. This unstable state not only seriously affects the accuracy and consistency of drilling, but also leads to excessive stress and potential damage to the guide rail material. Over time, this will not only reduce the service life of the guide rail, but may also threaten the stability and safety of the entire system.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for drilling guide rails, comprising a base, clamping seats on both sides of the top of the base, a lifting plate at the center of the upper end of the base, vertical grooves at the center of opposite sides of the two clamping seats, electric push rods fixedly installed on both sides of the top of the base, a sliding groove at the center of the top of the lifting plate, a support block at the center of the upper end of the lifting plate, a slider fixedly connected to the center of the bottom of the support block, an L-shaped plate fixedly connected to the center of the rear surface of the support block, a pull rod at the center of the bottom of the L-shaped plate, the upper end of the pull rod extending through to the outside of the L-shaped plate and fixedly connected to a connecting plate, a spring sleeved on the surface of the pull rod, and friction plates fixedly installed at the bottom of the lifting plate and the top of the connecting plate.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This guide rail drilling clamping device, through the design of a lifting plate, electric actuator, support block, slide groove, slider, L-shaped plate, pull rod, connecting plate, friction plate, and spring, and the precise control of the electric actuator, can smoothly push the lifting plate up or down, thereby driving the support block to move precisely below the position on the guide rail where drilling is required, achieving stable support for the guide rail. This design not only improves the efficiency of drilling operations but also significantly enhances drilling accuracy and safety, preventing the drill bit from bending and damaging the guide rail. Furthermore, when the position of the support block needs to be adjusted to adapt to different drilling requirements, the operator... Simply pull down the lever to separate the friction plate on the connecting plate from the friction plate below the lifting plate, thus releasing the locking state of the support block. Subsequently, the support block can be easily moved to any desired drilling position on the guide rail by the slider sliding flexibly in the groove. After adjustment, release the lever, and the spring will use its restoring property to quickly push the connecting plate upward, so that the two friction plates make tight friction contact, thereby quickly and reliably repositioning the support block. This process is not only simple and quick to operate, but also accurate and stable in positioning, greatly improving work efficiency and flexibility. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a clamping device for drilling guide rails, including a base 1, clamping seats 2 are provided on both sides of the top of the base 1, a lifting plate 3 is provided at the center of the upper end of the base 1, vertical grooves 15 are provided at the center position of the opposite side of the two clamping seats 2, electric push rods 4 are fixedly installed on both sides of the top of the base 1, a sliding groove 6 is provided at the center of the top of the lifting plate 3, a support block 5 is provided at the center position of the upper end of the lifting plate 3, a slider 7 is fixedly connected to the center of the bottom of the support block 5, an L-shaped plate 8 is fixedly connected to the center of the rear surface of the support block 5, a pull rod 9 is provided at the center of the bottom of the L-shaped plate 8, the upper end of the pull rod 9 extends through to the outside of the L-shaped plate 8 and is fixedly connected to a connecting plate 10, a spring 12 is sleeved on the surface of the pull rod 9, and friction plates 11 are fixedly installed at the bottom of the lifting plate 3 and the top of the connecting plate 10.

[0015] The two ends of the lifting plate 3 extend to the outside of the two vertical slots 15 respectively. The electric push rod 4 is fixedly connected to the drive shaft through its top output end. The upper ends of the two drive shafts are fixedly connected to the two sides of the bottom of the lifting plate 3 respectively, allowing the lifting plate 3 to move vertically in the vertical slots 15.

[0016] The lower end of the slider 7 extends into the interior of the slide groove 6 and slides in connection with the inner wall of the slide groove 6, so that the support block 5 can move left and right by sliding the slider 7 inside the slide groove 6. The bottom of the spring 12 is fixedly connected to the upper end face of the L-shaped plate 8, and the top of the spring 12 is fixedly connected to the bottom of the connecting plate 10. The two friction plates 11 are in contact with each other, and the friction force can position the support block 5 on the lifting plate 3.

[0017] A bidirectional screw 13 is centrally located within the base 1. One end of the bidirectional screw 13 is movably connected to a bearing fixedly installed at the center of one side of the base 1. The other end of the bidirectional screw 13 extends through to the outside of the base 1 and is fixedly mounted with a handle. Nut blocks 14 are threadedly connected to both sides of the surface of the bidirectional screw 13. Movable slots are provided on both sides of the top of the base 1. An extension post is fixedly connected to the center of the top of each of the two nut blocks 14. The tops of the two extension posts extend through to the outside of the two movable slots and are fixedly connected to the bottoms of the two clamps 2. By rotating the handle, the bidirectional screw 13 is rotated, thereby causing the two nut blocks 14 to synchronously drive the clamps 2 to move relative to each other or back to back, which facilitates matching guide rails of different lengths.

[0018] Each of the two clamping seats 2 has a support plate 16 fixedly connected to its top position on opposite sides. The upper end of each support plate 16 is threaded with an adjusting screw 17. A clamping plate 18 is provided at the upper end of the support plate 16. The lower end of the adjusting screw 17 extends through to the outside of the clamping seat 2 and is movably connected to a bearing fixedly installed at the top center of the clamping plate 18. A guide block is fixedly connected to the center of each of the two clamping plates 18 on opposite sides. A guide groove is provided at the top position on opposite sides of each of the two clamping seats 2. The two guide blocks are slidably connected to the two guide grooves respectively. By rotating the adjusting screw 17, the clamping plate 18 is pushed to move vertically, which is used to clamp and fix the two ends of the guide rail on the clamping seat 2.

[0019] Both sides of the base 1 are fixedly connected to mounting feet, and the upper end of the mounting feet is provided with mounting holes for fixing the base 1 in a designated area.

[0020] A rubber plate is fixedly installed on the top of the support block 5 to provide a buffer and prevent the impact force generated during drilling from damaging the guide rail. Sponge plates are fixedly installed on the top of the support plate 16 and the bottom of the clamping plate 18 to protect the surface of the guide rail from being pinched.

[0021] Working Principle: First, preliminary adjustments are made to accommodate guide rails of different sizes. The operator rotates the handle on the outside of the base 1, driving the bidirectional screw 13 to rotate. Since both sides of the bidirectional screw 13 are threaded with nut blocks 14, as the screw rotates, the two nut blocks 14 move synchronously towards the center or sides, thereby driving the two clamps 2 to move relative to each other or away from each other through the extension column, until the distance between the clamps 2 matches the width of the guide rail to be processed. Next, the guide rail is clamped and fixed. After the clamps 2 are adjusted to the appropriate distance, the operator rotates the adjusting screw 17 on the support plate 16. The lower end of the adjusting screw 17 is movably connected to the bearing fixedly installed at the top center of the clamp 18. Therefore, as the adjusting screw 17 rotates, the clamp 18 moves vertically along the guide groove, gradually approaching and clamping both ends of the guide rail. Since sponge plates are fixedly installed at the bottom of the clamp 18 and the top of the support plate 16, this process is both stable and safe, effectively preventing... To prevent damage to the guide rail surface, after clamping the guide rail, the support block 5 is precisely adjusted to align with the drilling area. The operator first pulls down the lever 9 to separate the friction plate 11 on the connecting plate 10 from the friction plate 11 below the lifting plate 3, releasing the lock on the support block 5. Then, by sliding the slider 7 in the groove 6, the support block 5 is moved horizontally to below the designated drilling area on the guide rail. After adjustment, the lever 9 is released, and the spring 12 uses its restoring property to push the connecting plate 10 upward, causing the two friction plates 11 to re-contact and generate friction, thereby firmly positioning the support block 5 on the lifting plate 3. Finally, the electric push rod 4 is activated, pushing the lifting plate 3 and support block 5 upward through its top drive shaft until the rubber plate on top of the support block 5 is in close contact with the drilling area of ​​the guide rail and provides stable support. At this point, the guide rail is firmly clamped and precisely supported in the drilling position, providing good conditions for subsequent drilling operations.

[0022] In summary, this guide rail drilling fixture, through the design of the lifting plate 3, electric actuator 4, support block 5, slide groove 6, slider 7, L-shaped plate 8, pull rod 9, connecting plate 10, friction plate 11, and spring 12, and the precise control of the electric actuator 4, can smoothly push the lifting plate 3 up or down, thereby driving the support block 5 to move precisely below the position on the guide rail where drilling is required, achieving stable support for the guide rail. This design not only improves the efficiency of drilling operations but also significantly enhances the accuracy and safety of drilling, preventing the drill bit from bending and damaging the guide rail. Furthermore, when the position of the support block 5 needs to be adjusted to adapt to different drilling requirements, the operator... The operator only needs to pull down the lever 9 to separate the friction plate 11 on the connecting plate 10 from the friction plate 11 below the lifting plate 3, thereby releasing the locking state of the support block 5. Then, the support block 5 can be easily moved to any desired drilling position on the guide rail by the slider 7 sliding flexibly in the slide groove 6. After adjustment, the lever 9 is released, and the spring 12 uses its restoring property to quickly push the connecting plate 10 upward, so that the two friction plates 11 are in close frictional contact, thereby quickly and reliably repositioning the support block 5. This process is not only simple and quick to operate, but also accurate and stable in positioning, greatly improving work efficiency and flexibility.
