Abstract
Description
Technical Field
[0001] The utility model belongs to the field of drilling equipment, and particularly relates to a linear guide drilling device. Background Art
[0002] In the field of machining, linear guides, as precision transmission components, are widely used in various mechanical equipment, such as numerically controlled machine tools, automation equipment, and industrial robots. The accuracy and performance of linear guides directly affect the operating stability and machining accuracy of the entire equipment. However, in the production and processing of linear guides, especially in the drilling process, traditional methods face many challenges and need to be solved urgently.
[0003] When drilling traditional linear guides, since the linear guide needs to be re-clamped after each hole is drilled, this repetitive operation not only takes a long time but also increases labor costs. Especially in a large-scale production environment, this inefficient processing method seriously restricts the improvement of production capacity.
[0004] After clamping the linear guide multiple times, due to the uncertainty of manual operation and the slight deviation of the mechanical structure, a large cumulative error will still occur after multiple clamps. This error not only affects the accuracy of the linear guide but may also further affect the assembly and operating accuracy of subsequent equipment. Summary of the Utility Model
[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a linear guide drilling device to solve the problems of low drilling efficiency and large errors in the existing linear guide drilling.

[0026] Next, in combination with the appendix Figures 1-6 , the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0027] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0028] As Figure 1 shown, a linear guide drilling device includes a frame 1, a clamping mechanism is provided on the frame 1, and the linear guide is clamped in the clamping mechanism, as Figure 2As shown in the figure, limiting grooves 17 are provided on both sides of the frame 1. A cross beam 14 is slidably connected in the limiting grooves 17. Second telescopic mechanisms 15 are provided on both sides of the frame 1. One end of the second telescopic mechanism 15 is connected to the cross beam 14. A plurality of drilling machines 18 are provided on the cross beam 14. A drill bit 19 is installed at the lower part of the drilling machine 18. When drilling on the linear guide rail, the second telescopic mechanism 15 drives the multiple drilling machines 18 on the cross beam 14 to move downward synchronously, and the linear guide rail is drilled simultaneously by the multiple drilling machines 18. Compared with the traditional method of drilling single holes one by one, the drilling cycle is greatly shortened. This parallel processing mode significantly improves the overall efficiency of the production line, especially in large-scale production, and its advantages are more obvious. In addition, when drilling multiple holes simultaneously, there is no need to frequently disassemble and clamp the linear guide rail, which not only reduces manual intervention and clamping time, but also avoids the position deviation and cumulative error that may be caused by multiple clampings, thereby improving the drilling accuracy and consistency. The drill bit 19 adopts a two-stage stepped drill bit 19, realizing the one-time forming of the counterbore, further reducing the number of clampings of the linear guide rail, and improving the drilling efficiency and accuracy of the linear guide rail.
[0029] As Figure 3 , Figure 4 shown, the clamping mechanism includes multiple groups of symmetrically arranged clamping plates 11. One end of the clamping plate 11 is rotatably connected to the inner wall of the frame 1 through a pin shaft 12. The other end of the clamping plate 11 is hinged with a second connecting plate 13. The clamping plates 11 on both sides are arranged in a V shape. An arc-shaped groove 4 is provided at the upper part of the frame 1, and the clamping plates 11 are arranged inside the arc-shaped groove 4. A connecting frame 5 is provided inside the frame 1. Push plates 8 are fixedly connected to both sides of the connecting frame 5. A first connecting plate 9 is provided on one side of the push plate 8. A first telescopic mechanism 10 is provided on one side of the frame 1. One end of the first telescopic mechanism 10 is connected to the connecting frame 5. When clamping the linear guide rail, the first telescopic mechanism 10 extends, driving the connecting frame 5 to move to the right side. The first connecting plates 9 on both sides of the connecting frame 5 push the clamping plates 11 on both sides to move towards the middle, realizing the clamping operation of the linear guide rail.
[0030] The first telescopic mechanism 10 and the second telescopic mechanism 15 include but are not limited to hydraulic cylinders, air cylinders, and servo electric cylinders. In this embodiment, both the first telescopic mechanism 10 and the second telescopic mechanism 15 adopt hydraulic cylinders.
[0031] Preferably, a torsion spring (not shown in the figure) is provided on the pin shaft 12. One torsion arm of the torsion spring abuts against the clamping plate 11, and the other torsion arm abuts against the side wall of the frame 1, facilitating the automatic reset of the clamping plate 11 when the clamping mechanism is loosened.
[0032] As Figure 4As shown in the figure, guide rails 6 are provided on both sides of the bottom of the frame 1. A number of sliders 7 are provided at the lower part of the connecting frame 5. The sliders 7 are slidably mounted on the guide rails 6, restricting the movement direction of the connecting frame 5 and ensuring the clamping accuracy of the clamping mechanism.
[0033] As Figure 2 shown in the figure, a material leakage groove 16 is provided on the frame 1. The linear guide rail is clamped on the upper part of the material leakage groove 16. The width of the material leakage groove 16 is greater than the diameter of the counterbore of the linear guide rail and less than the width of the linear guide rail. A chip collection box 2 is provided at the lower part of the frame 1. When drilling the linear guide rail, the iron chips at the lower part fall into the chip collection box 2 through the material leakage groove 16, facilitating the collection of iron chips.
[0034] As Figure 1 、 Figure 2 shown in the figure, a number of casters 3 are provided at the lower part of the chip collection box 2, facilitating the transfer and cleaning of the chip collection box 2.
[0035] As Figure 1 、 Figure 6 shown in the figure, a sleeve 20 is connected to one side of the lower part of the drilling machine 18. The sleeve 20 is slidably sleeved on the cross beam 14. An adjusting bolt 21 is threadedly connected to the sleeve 20. The bottom of the adjusting bolt 21 abuts against the cross beam 14, facilitating the adjustment of the distance between each drilling machine 18 according to the drilling spacing of the linear guide rail.
[0036] The above content is only an example and description of the structure of the present invention. Those skilled in the art of this technology can make various modifications, supplements or use similar methods to replace the specific embodiments described, as long as they do not deviate from the structure of the invention or exceed the scope defined by this claim book, they should fall within the protection scope of the present invention.
