Description

Technical Field

[0001] This utility model relates to the field of installation structures, specifically to a linear guide rail adaptive installation structure. Background Technology

[0002] Linear guide rail self-adaptive mounting structures are widely used in precision machinery, automation equipment, industrial robots, and CNC machine tools, and are a key fundamental component for achieving high-precision linear motion. This structure needs to maintain high matching precision between the slider and the guide rail during dynamic motion, which directly affects the stability, positioning accuracy, and service life of the motion system.

[0003] Existing linear guide rail installation structures typically employ a rigid connection between the base and the slider guide rail, specifically including two basic structural forms: direct welding fixation and bolt locking fixation. In the direct welding scheme, the sliders are paired and installed on the guide rail, and the sliders form a permanent connection with the actuator through the weld seam; its positional accuracy depends entirely on the assembly accuracy before welding. In the bolt locking scheme, mechanical fixation is achieved through a group of bolts with pre-drilled holes; the sliders are rigidly connected to the actuator and paired with the guide rail, allowing them to reciprocate along the guide rail.

[0004] However, existing technologies still have certain significant drawbacks: First, due to the non-adjustable nature of direct welding structures, they cannot compensate for manufacturing errors of individual parts, flatness deviations of the base, and assembly stress caused by welding thermal deformation, resulting in additional resistance and vibration during slider movement. Second, although bolt locking schemes have the characteristic of being detachable, they are limited by machining accuracy (such as hole position deviations and surface roughness), and differences in bolt preload can cause local stress concentration. The hard connection characteristic causes the slider to bear non-uniform loads, which aggravates the wear of the guide rail-slider mating surface and shortens the service life of the moving pair. Therefore, it is necessary to develop an installation structure with adaptive compensation capabilities to achieve stress relief and error absorption through adjustment mechanisms. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned deficiencies by providing an adaptive mounting structure for linear guide rails. This solves the technical problem in the background art of how to adjust and release the stress connecting the linear guide rail and the mounting structure, thereby enhancing the stability and lifespan of the rail.

[0006] The objective of this utility model is achieved through the following means:

[0007] The linear slide rail self-adaptive mounting structure includes two sets of symmetrically arranged linear slide rails and a support frame mounted on the linear slide rails. The linear slide rails consist of sliders and vertically arranged guide rails. The sliders are paired with the guide rails, allowing the sliders to move up and down and reciprocate along the vertical guide rails. One end of the support frame has a connecting end, and a mounting block is connected to the side of the connecting end. Two insertion limiting holes are opened on the side of the connecting end, and the mounting block is positioned between the two insertion limiting holes. The slider has two connecting blocks for connecting the mounting blocks. The ends of the two connecting blocks each have adjusting ends for inserting into the insertion limiting holes. The two connecting blocks are locked to both ends of the mounting block by bolts, allowing the two connecting blocks to clamp the mounting block. When the connecting blocks and the mounting block are locked, the adjusting ends can adaptively adjust along the axial direction of the insertion limiting holes.

[0008] Furthermore, as described above, there are two connecting ends, and the two connecting ends are formed on one side of the support frame. The two connecting ends are respectively paired with two sets of linear slide rails.

[0009] By using a symmetrical layout of dual connecting ends, the force on both sides of the support frame is evenly distributed, and the two sets of linear slide rails are symmetrically installed. This avoids the deviation of the slider's movement trajectory caused by the flatness deviation of the base in the traditional single-sided connection scheme, thereby reducing the frictional resistance of the movement and improving the stability of the slider driving the support frame to rise and fall.

[0010] Furthermore, as described above, a fixing hole is provided on the side of the connecting end, and a mounting hole is provided on the mounting block to match the fixing hole, so that the mounting block is fixedly connected to the fixing hole by bolts passing through the mounting hole, and the mounting block is installed on the side of the connecting end.

[0011] Bolted connections replace welding for fixed installation, creating an adjustable mounting interface. Fine-tuning of bolt preload compensates for manufacturing errors and flatness deviations in parts, avoiding the accumulation of assembly stress caused by welding thermal deformation. Furthermore, the detachable nature of the bolted connection facilitates adjustments to the installation position during later maintenance.

[0012] Furthermore, as described above, the end of the adjusting end forms a protruding insertion part, which is then paired with the insertion limiting hole for insertion connection. The adjusting end is provided with a through adjusting hole, and both ends of the mounting block are provided with positioning holes that are paired with the adjusting hole, so that the bolt passes through the adjusting hole and locks in place with the positioning hole.

[0013] The guide structure of the insertion limiting hole allows the insertion part of the adjusting end to form an adaptive adjustment within the insertion limiting hole. When the bolt is tightened, the locking connection between the adjusting hole and the positioning hole allows the connecting block to slide along the insertion limiting hole of the connecting end through the mating of the insertion part and the insertion limiting hole, forming an adaptive adjustment. The preload of the bolt and the adjusting hole and positioning hole absorbs the manufacturing errors of the parts (such as the stress on the sliding surface of the slider and the slide rail) and the installation stress (such as the local stress concentration caused by the difference in bolt preload). The non-uniform load on the mating surface of the guide rail and the slider is released by the axial displacement of the insertion end along the insertion limiting hole, avoiding the stress concentration and accelerated wear problems caused by the "hard connection" in the traditional bolt locking scheme.

[0014] Furthermore, as described above, one end of the connecting block has a matching groove for the slider, allowing the connecting block to match the slider through the groove. An assembly hole is provided on the connecting block, allowing the connecting block to be locked to the slider by passing a bolt through the assembly hole.

[0015] The slot structure enables mechanical positioning of the connecting block and the slider, ensuring assembly accuracy; bolt tightening provides reliable connection strength.

[0016] The beneficial effects of this utility model are as follows: By opening two insertion limiting holes on the side of the support frame connection end and setting a connecting block with an adjusting end, the adjusting end can be adaptively adjusted along the axial direction of the insertion limiting hole. The two connecting blocks are locked to both ends of the mounting block by bolts to form a clamping structure. During the locking process, the adjusting end of the connecting block adaptively adjusts along the axial direction of the insertion limiting hole, which can disperse the local stress concentration caused by the difference in the preload of the bolt group, avoid the slider bearing non-uniform load caused by hard connection, thereby reducing the wear of the guide rail and slider mating surface, and extending the service life of the movement. Through the locking connection structure between the connecting block and the mounting block, the detachable characteristics of the bolt locking scheme are retained, and the assembly problem caused by the limitation of machining accuracy (such as hole position deviation and surface roughness) is solved through the adaptive adjustment mechanism. This realizes the flexible adjustment and stress relief of the installation structure, and improves the stability and service life of use. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer, the following describes the solution in further detail with reference to the accompanying drawings and embodiments.

[0030] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this scheme and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] In this embodiment, refer to Figures 1-5The specific implementation of the linear slide rail adaptive installation structure includes two sets of symmetrically arranged linear slide rails and a support frame 300 mounted on the linear slide rails. The linear slide rails are composed of sliders 100 and vertically arranged guide rails 200. The sliders 100 and guide rails 200 are paired and connected, allowing the sliders 100 to move up and down and reciprocate along the vertical guide rails 200. One end of the support frame 300 forms a connecting end 301, and a mounting block 400 is connected to the side of the connecting end 301. Two insertion limiting holes 302 are opened on the side of the connecting end 301. The slider 100 is positioned between two insertion limiting holes 302. It is provided with two connecting blocks 500 for connecting the mounting block 400. The ends of the two connecting blocks 500 are respectively formed with adjusting ends 501 for passing through the insertion limiting holes 302. The two connecting blocks 500 are locked to the two ends of the mounting block 400 by bolts, so that the two connecting blocks 500 can clamp the mounting block 400. When the connecting blocks 500 and the mounting block 400 are locked, the adjusting ends 501 can be adaptively adjusted along the axial direction of the insertion limiting holes 302.

[0032] The connection structure between the two sets of symmetrically arranged linear slide rails and the support frame, combined with the clamping effect of the connecting blocks on the mounting blocks, forms a stable support system and improves the overall structural motion stability.

[0033] Two connection ends 301 are provided, and the two connection ends 301 are formed on one side of the support frame 300. The two connection ends 301 are respectively paired with two sets of linear slide rails.

[0034] By using the symmetrical layout of the double connecting ends 301, the force on both sides of the support frame 300 is evenly distributed, and the two sets of linear slide rails are symmetrically installed. This avoids the deviation of the slider 100's movement trajectory caused by the base flatness deviation in the traditional single-sided connection scheme, thereby reducing the frictional resistance of the movement and improving the stability of the slider 100 driving the support frame 300 to rise and fall.

[0035] The side of the connecting end 301 is provided with a fixing hole 303, and the mounting block 400 is provided with a mounting hole 401 that matches the fixing hole 303, so that the mounting block 400 is fixedly connected to the fixing hole 303 by bolts passing through the mounting hole 401. The mounting block 400 is installed on the side of the connecting end 301.

[0036] Bolted connections replace welding for fixed installation, creating an adjustable mounting interface. Fine-tuning of bolt preload compensates for manufacturing errors and flatness deviations in parts, avoiding the accumulation of assembly stress caused by welding thermal deformation. Furthermore, the detachable nature of the bolted connection facilitates adjustments to the installation position during later maintenance.

[0037] The end of the adjustment end 501 has a protruding insertion part 502, which is matched and inserted into the insertion limiting hole 302. The adjustment end 501 has a through adjustment hole 503. Both ends of the mounting block 400 have positioning holes 402 that match the adjustment hole 503, so that the bolt passes through the adjustment hole 503 and locks and positions itself with the positioning hole 402.

[0038] The guide structure of the insertion limiting hole 302 allows the insertion part 502 of the adjusting end 501 to form an adaptive adjustment within the insertion limiting hole 302. When the bolt is tightened, the locking connection between the adjusting hole 503 and the positioning hole 402 allows the connecting block 500 to slide along the insertion limiting hole 302 of the connecting end 301 through the mating of the insertion part 502 and the insertion limiting hole 302, forming an adaptive adjustment. The preload of the bolt and the adjusting hole 503 and positioning hole 402 absorbs the manufacturing errors of the parts (such as the stress on the sliding surface of the slider 100 and the slide rail) and the installation stress (such as the local stress concentration caused by the difference in bolt preload). The non-uniform load on the mating surface of the guide rail 200 and the slider 100 is released by the axial displacement of the insertion end along the insertion limiting hole 302, avoiding the stress concentration and accelerated wear problems caused by the "hard connection" in the traditional bolt locking scheme.

[0039] One end of the connecting block 500 has a matching groove 504 for the slider 100, allowing the connecting block 500 to mate with the slider 100 through the groove 504. The connecting block 500 also has an assembly hole 505, allowing the connecting block 500 to be locked to the slider 100 by bolts passing through the assembly hole 505. The groove 504 structure provides mechanical positioning between the connecting block 500 and the slider 100, ensuring assembly accuracy; the bolt locking provides reliable connection strength.

[0040] Specifically, in some embodiments, the guide rail 200 is vertically connected to the upright plate 600 by bolts. The upright plate 600 is equipped with a telescopic drive component (not shown). The telescopic end of the drive component is connected to the slider 100 via a drive plate, allowing the drive component to drive the slider 100 to reciprocate along the guide rail 200. Specifically, the telescopic drive component can be a multi-section telescopic rod, a telescopic cylinder, or a hydraulic cylinder, etc. How the slider 100 drives the support frame 300 to rise and fall along the guide rail 200 is a conventional technique used by those skilled in the art and does not substantially contribute to solving the application of the slider 100 and guide rail 200 in this solution. Therefore, this solution omits the drive connection between the telescopic drive component and the slider 100.

[0041] For example, the linear slide rail adaptive mounting structure in this embodiment is used in a midsole machine for producing shoe midsoles. By setting a mold structure on the support frame, the slider can drive the mold structure to rise or fall to the corresponding processing step.

[0042] The specific operating principle in this embodiment is as follows:

[0043] First, the guide rail 200 is vertically installed on the side of the upright plate 600. The slider 100 is paired with the guide rail 200, allowing the slider 100 to reciprocate along the guide rail 200. Second, the mounting block 400 is paired with the connecting end 301 of the support frame 300 via bolts, so that the mounting block 400 is connected to the outside of the connecting end 301. Bolts are then used to pair the connecting block 500 with the slider 100. Specifically, two connecting blocks 500 are connected to one slider 100, creating a gap between the two connecting blocks 500 for mounting the mounting block 400. At this point, the support frame 300 is paired with the mounting block 400 on the connecting end 301, and the connection is complete. The connector 301 is paired with the insert portion 502 on the two connecting blocks 500 through two insertion limiting holes 302 respectively. Finally, the bolt passes through the adjustment hole 503 and locks into the positioning hole 402 on the mounting block 400. When the bolt is locked, the insert portion 502 can slide along the insertion limiting hole 302 to form an adaptive adjustment. The preload of the bolt and the adjustment hole 503 and positioning hole 402 absorbs the manufacturing error and installation stress of the parts. It can disperse the local stress concentration caused by the difference in the preload of the bolt group, avoid the slider 100 bearing non-uniform load due to hard connection, thereby reducing the wear of the mating surface between the guide rail 200 and the slider 100 and extending the service life of the movement.

[0044] In summary, the locking connection structure between the connecting block 500 and the mounting block 400 not only retains the detachable characteristics of the bolt locking scheme, but also solves the assembly problems caused by machining accuracy limitations (such as hole position deviation and surface roughness) through the adaptive adjustment mechanism, thereby achieving flexible adjustment and stress relief of the mounting structure and improving the stability and service life of the device.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
