Description

Technical Field

[0001] This application belongs to the field of engineering machinery, and specifically relates to a convenient on-rail stop device for sliders. Background Technology

[0002] In outdoor engineering surveying or testing, when it is necessary to measure the attitude angle of guide rail components in mechanical equipment, measuring equipment can be used to measure the attitude angle of the guide rail. However, guide rail components are characterized by their narrow and long shape and small internal space, and the outdoor environment is also relatively harsh, making it difficult to quickly and directly measure the guide rail attitude angle using measuring equipment. Generally, a measuring fixture with a slider can be designed to assemble the measuring fixture with the guide rail component, and then the measuring equipment can be mounted on the measuring fixture to measure the guide rail attitude angle. However, in the above measurement method, in order to facilitate the assembly and disassembly of the measuring fixture, there will be a certain gap between the slider and the guide rail, which will prevent the measuring fixture from being reliably fixed on the guide rail, and also prevent attitude angle measurement when the guide rail component is at a large tilt angle. Figure 1 This represents the free state of the slider within the guide rail.

[0003] To solve the above problems, it is necessary to adopt corresponding methods to reliably fix the slider inside the guide rail component to ensure the reliability of the guide rail attitude angle measurement. Summary of the Invention

[0012] The stop assembly actively eliminates the free clearance between the slider and the guide rail through clamping or separating actions, preventing the slider from sliding due to vibration, tilt angle or external force during the measurement process, and significantly improving the stability and accuracy of the guide rail attitude angle measurement.

[0013] The stop assembly is compact and does not occupy the narrow gap space between the slider and the guide rail, adapting to the characteristics of guide rails that are "narrow and long with small internal space".

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0020] The first aspect of this application provides a convenient on-rail stop device for a slider, such as... Figure 2 It includes a guide rail component 1, a slider 2, and a stop component; the slider 2 is slidably connected to the guide rail component 1.

[0021] The stopping component includes a clamping rod 3 and a clamping block 4; the clamping rod 3 is located in the middle of the slider 2, and the clamping block 4 is located between the slider 2 and the guide rail component 1; one end of the clamping rod 3 is located on the outside of the slider 2, and the other end is connected to the clamping block 4; the clamping rod 3 can drive the clamping block 4 to approach the guide rail component 1 to clamp the guide rail component 1, or separate from the guide rail component 1.

[0022] During operation, after the launching device is fixed, the slider 2 is first fixed in the guide rail component 1. The slider 2 with the stop component is first pushed into the appropriate position in the guide rail component 1. The clamping block 4 is brought close to the inner upper surface of the guide rail component 1 and clamped by the clamping rod 3. At this time, under the action of the reverse support force, the slider 2 is pressed into the guide rail and thus fixed, so that the guide rail attitude angle can be accurately measured.

[0023] This allows for the fixing of sliders 2 of different sizes in the guide rail component 1; the structure is simple and compact, and the operation is convenient.

[0024] In one embodiment, the clamping rod 3 is provided with external threads, and the middle part of the slider 2 is provided with a threaded hole. The clamping rod 3 is threadedly engaged with the threaded hole of the slider 2. The end of the clamping rod 3 is provided with a spherical structure, and a spherical groove is provided in the spherical structure. The clamping block 4 includes a ball head 5 and a stop plate 6 integrally connected with the ball head 5. The ball head 5 is hinged to the spherical groove. The stop plate 6 is disc-shaped and is provided with a clamping surface that can clamp the stop component.

[0025] The clamping rod 3 is threaded together, and the stop plate 6 is clamped by rotating the clamping rod 3. The ball joint design can increase the contact area and friction coefficient between the slider 2 and the guide rail, so as to fix the slider 2 under different guide rail posture angles.

[0026] Preferably, the clamping surface of the stop disc 6 is provided with felt 7, and the end of the clamping rod 3 away from the clamping block 4 is provided with a hexagonal prism. The felt 7 can be used to protect the metal surface from damage and increase the friction of the clamping surface during the fixing process of the slider 2; the end of the clamping rod 3 is provided with a hexagonal prism structure to facilitate rotation.

[0027] like Figure 3 In another embodiment, the clamping rod 3 and the slider 2 are slidably engaged, the clamping block 4 is threadedly connected to the clamping rod 3, the slider 2 has a clamping groove at the position corresponding to the end of the clamping rod 3, the end of the clamping rod 3 is provided with a top plate 8, the slider 2 is provided with a cover 9 and a long bolt 10 on the outside of the top plate 8, the cover 9 is located on the outside of the top plate 8, the head of the long bolt 10 is located inside the slider 2, the long bolt 10 and the cover 9 are slidably engaged, and a tightening nut 11 is threadedly connected to the long bolt 10 at the position corresponding to the outside of the cover 9.

[0028] The top plate 8 on the pressure rod 3 is fixed by the cover 9, and then the nut 11 is tightened to press the top plate 8, which in turn drives the pressure rod 3 to press the pressure block 4 onto the stop component, and the slider 2 is fixed by the reaction force. Furthermore, this design eliminates the need for tightening the pressure rod 3; it can be directly inserted for assembly. The threaded connection between the pressure block 4 and the pressure rod 3 allows for easy disassembly and assembly, making the overall design convenient to use.

[0029] Preferably, the distance from the bottom of the clamping groove to the stop component is greater than or equal to the distance from the top plate 8 to the stop component, so that the clamping rod 3 has sufficient distance to clamp the clamping block 4.

[0030] In summary, this application has the following advantages:

[0031] The stop assembly actively eliminates the free clearance between the slider and the guide rail through clamping or separating actions, preventing the slider from sliding due to vibration, tilt angle or external force during the measurement process, and significantly improving the stability and accuracy of the guide rail attitude angle measurement.

[0032] The stop assembly is compact and does not occupy the narrow gap space between the slider and the guide rail, adapting to the characteristics of guide rails that are "narrow and long with small internal space". Two modes are available: threaded adjustment and sliding locking, which can be flexibly switched according to the outdoor environment to meet the needs of "large tilt angle measurement in harsh environments".

[0033] The slider-on-rail stop device systematically solves the problem of unreliable fixation caused by gaps in traditional sliders through multiple technological innovations such as threaded adjustment, adaptive hinge, felt friction enhancement and sliding locking.
