Description

Technical Field

[0001] This utility model relates to the field of vehicle support leg processing technology, and in particular to a drilling and positioning fixture for vehicle support legs. Background Technology

[0002] Vehicle support legs are mechanical devices used to support the vehicle body, compartment, or onboard equipment. Their main functions are to maintain vehicle stability, reduce the load on the tires and suspension system, and provide load-bearing support. Their structure typically includes components such as an inner sleeve, an outer sleeve, and a screw, and height adjustment is achieved through hydraulic or helical design.

[0003] In existing technologies, most vehicle-mounted support leg devices (such as those for aerial work platforms and dump trucks) use hydraulic systems. These systems use an engine-driven hydraulic pump to generate pressurized oil, which is then distributed to the support leg cylinders via control valves. This oil pushes the pistons to extend and retract, achieving lifting and lowering. For example, a fork-shaped base works with a limit steel cylinder and a bearing for limiting the position, while a lead screw and a copper nut work together to adjust the height. However, when drilling holes for some vehicle-mounted support leg devices, it is necessary to adjust the position of the support legs to drill holes for different sizes, which reduces processing efficiency.

[0035] Reference Figures 1 to 8 A protective shell 20 is fixedly connected to the top of the base plate 1. A motor 21 is fixedly connected to the outside of the protective shell 20. A bidirectional threaded rod 22 is fixedly connected to the drive end of the motor 21, and the bidirectional threaded rod 22 passes through the protective shell 20 to provide power for the bidirectional threaded rod 22 to rotate. A movable plate 23 is threadedly connected to the outside of the bidirectional threaded rod 22. A clamping plate 24 is fixedly connected to the top of the movable plate 23, and the movable plate 23 is slidably connected to the top of the protective shell 20. A workpiece 25 is provided on the outside of the clamping plate 24 to clamp the workpiece 25.

[0036] Reference Figures 1 to 8 A fixing plate 17 is fixedly connected to the top of motor 2 14. A spring-loaded telescopic rod 4 18 is fixedly connected to the outside of fixing plate 17 to provide elasticity. A connecting rod 19 is fixedly connected to one end of the spring-loaded telescopic rod 4 18. A telescopic rod 3 16 is fixedly connected to the outside of connecting rod 19 to provide a connection. The inside of telescopic rod 3 16 is fitted over the outside of drilling rod 15, and one end of telescopic rod 3 16 is fixedly connected to the outside of motor 2 14 to prevent debris generated during drilling from flying out.

[0037] Reference Figures 1 to 8 One end of the telescopic rod 16 is fixedly connected to a dust cover, and the outside of the dust cover is fixedly connected to a suction pipe 27. One end of the suction pipe 27 is fixedly connected to an air pump 26, and the top output end of the air pump 26 is fixedly connected to a dust delivery pipe 28. The outside of the air pump 26 is fixedly connected to the outside of the protective shell 20 and is used to suck up the debris splashed during drilling. The outside of the slide plate 10 is slidably connected to the inside of the slide rail plate 13. The two ends of the limiting rod 7 are fixedly connected to the outside of the sliding block 8 and are used to allow the slide rail plate 13 to slide.

[0038] Working principle: When drilling holes in workpieces 25 of different sizes, first place the workpiece 25 on the protective shell 20, start the motor 21 to drive the bidirectional threaded rod 22 to rotate, and let the moving plate 23 slide along the protective shell 20, thereby driving the clamping plate 24 to move, so that the clamping plate 24 clamps the two ends of the workpiece 25 to achieve the effect of fixing the workpiece 25; then start the cylinder 11 to drive the telescopic rod 12 to extend and retract, and the sliding block 8 slides in the slide plate 10. The sliding block 8 is connected to the limiting rod 7 and the threaded rod 6. When the moving plate 5 moves downward, it drives the limiting rod 7 and the threaded rod 6 to move at the same time, so that the motor 14 connected to the moving plate 5 moves accordingly. Adjust the drilling rod 15 at the drive end of the motor 14 so that the position of the workpiece 25 to be drilled is on the same horizontal plane.

[0039] Then, start motor 9 to drive threaded rod 6 to rotate, so that threaded rod 6 drives moving plate 5 to move along limiting rod 7 through thread. Adjust the position of moving plate 5 and motor 14 so that drilling rod 15 is aligned with the drilling point and slide plate 10 slides in slide rail plate 13. Start cylinder 3 to drive telescopic rod 4 to extend and retract, thereby controlling slide plate 10 to move along slide rail plate 13, so that drilling rod 15 approaches the drilling point of workpiece 25. At the same time, start motor 14 to make drilling rod 15 rotate.

[0040] When the drill rod 15 moves, the dust cover on the outside of the drill rod 15 first contacts the surface of the workpiece 25, and the dust cover stops moving. At this time, the dust cover cannot move, and the motor 2 14 and the drill rod 15 move, pressing the telescopic rod 3 16 to extend or retract it. At the same time, the connecting rod 19 on the dust cover also cannot move, and the motor 2 14 moves with the fixing plate 17, also pressing the elastic telescopic rod 4 18 to deform it. When the dust cover and the telescopic rod 3 16 allow the drill rod 15 to drill, the dust cover and the telescopic rod 3 16 prevent the drill rod 15 from drilling. To prevent debris from flying everywhere, the air pump 26 is activated to generate suction, which absorbs the debris inside the dust cover through the suction pipe 27 and transports it out through the dust delivery pipe 28, thus preventing debris from flying into the operator's eyes and protecting the operator's eyes. When drilling is completed, the operation is reversed as described above, allowing the drill rod 15 to move towards the support plate 2. At the same time, the elastic telescopic rod 18, which has lost its compression, begins to rebound, driving the connecting rod 19 and the dust cover to move, thereby causing the telescopic rod 16 to return to its original length.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
