Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, specifically a double-support linear guide. Background Technology

[0002] In fields such as automation equipment, precision machine tools, and conveying machinery, linear guides are the core transmission structure for realizing the linear reciprocating motion of components. Their operating accuracy, stability, and ease of maintenance directly affect the overall working performance of the equipment. Most linear guides on the market currently adopt a single support or fixed-spacing double support structure. When facing different load requirements or assembly error adjustment scenarios, the installation position of the slide bar is difficult to adapt flexibly, resulting in limited overall adjustment capability of the guide. Furthermore, existing dust removal structures mostly adopt a fixed brush or a single dust scraper design, which has limited dust removal effect. Moreover, after long-term use, the dust removal components are prone to dust accumulation and blockage, requiring frequent disassembly and maintenance. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a double-support linear guide rail to solve the problems mentioned in the background. This utility model has a novel structure. By setting an adjustment component, and utilizing the vertical sliding cooperation between the adjustment frame and the limiting groove, and the displacement cooperation between the adjustment block and the adjustment frame, the slide rod can be precisely adjusted in multiple dimensions in the horizontal and vertical directions. It can flexibly adapt to the assembly requirements and load conditions of different equipment, effectively solving the problems of fixed slide rod position and poor adjustment capability in traditional guide rails, and reducing the risk of motion failure caused by assembly errors. The dust removal component adopts a design that combines a gradually shrinking dust removal ring with an automatic cleaning scraper block. The dust removal ring is tightly attached to the slide rod to achieve initial dust removal, and the scraper block automatically cleans the surface of the dust removal ring under the linkage of the friction wheel and friction strip, reducing the accumulation of impurities and improving the dust removal effect and continuous dust removal capability.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a double-support linear guide rail, comprising a base plate, with baffles fixedly connected to both sides of the upper part of the base plate, and two symmetrically arranged sliding rods between the two baffles. An adjustment assembly is provided between the two sliding rods and the baffles on both sides. A slider is provided on the upper side of the base plate between the two baffles, and connecting blocks that slide and engage with the two sliding rods are fixedly connected to both sides of the bottom of the slider. A dust removal assembly that engages with the sliding rods is provided on the connecting blocks. A servo motor is fixedly installed on the outer side of one of the baffles, and the output shaft of the servo motor is fixedly connected to a screw that rotates between the two baffles. A fixing block that threadedly engages with the screw is fixedly connected to the bottom of the slider.

[0005] Furthermore, two adjustment grooves corresponding to the slide rod are provided on the sides of the baffles on both sides. Limiting grooves are provided on the inner walls of the two sets of opposing adjustment grooves, and the two sets of limiting grooves are arranged vertically.

[0006] Furthermore, the adjustment assembly includes two adjustment frames that slide between two sets of opposite inner walls of the adjustment groove. The two adjustment frames are vertically arranged, and each of the outer walls of the two adjustment frames is fixedly connected with a limiting block that slides with the limiting groove.

[0007] Furthermore, an adjustment block is slidably fitted between the inner walls of the two adjustment frames, and a displacement block is fixedly connected to each of the two symmetrical outer sides of the adjustment block. The inner walls of the two adjustment frames are provided with displacement grooves that slidably fit with the two sets of displacement blocks of the adjustment block.

[0008] Furthermore, both ends of the slide rod are fixedly connected to a fixing stud located in the through hole in the middle of the two side adjustment blocks, and the fixing stud is threaded with a fixing nut that abuts against the adjustment block.

[0009] Furthermore, the dust removal assembly includes dust removal rings symmetrically arranged on both sides of the connecting block. The dust removal rings are coaxially sleeved around the periphery of the slide rod. The inner diameter of the dust removal rings is gradually tapered along the direction from the connecting block to the slide rod and is tightly fitted to the surface of the slide rod. A scraping block that mates with the surface of the dust removal rings is provided on one side of the connecting block.

[0010] Furthermore, a connecting ring is fixedly connected to one side of the dust removal ring, and annular grooves that rotate and cooperate with the connecting ring are opened on both sides of the connecting block. Friction wheels are fixedly connected to the periphery of the annular grooves, and a fixing frame is fixedly connected to one side of the connecting block. Friction strips that cooperate with the friction wheels are slidably fitted on the inner wall of the fixing frame.

[0012] The beneficial effects of this utility model are:

[0013] 1.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please refer to Figures 1 to 5This utility model provides a technical solution: a double-support linear guide rail, including a base plate 1, with baffles 2 fixedly connected to both sides of the upper part of the base plate 1, two symmetrically arranged sliding rods 3 between the two baffles 2, and an adjustment assembly 4 between the two sliding rods 3 and the two side baffles 2. A slider 6 is arranged on the upper side of the base plate 1 between the two side baffles 2, and connecting blocks 7 are fixedly connected to both sides of the bottom of the slider 6, which slide and cooperate with the two sliding rods 3. A dust removal assembly 8 that cooperates with the sliding rods 3 is arranged on the connecting blocks 7. A servo motor 5 is fixedly installed on the outer side of one of the baffles 2, and the output shaft of the servo motor 5 is fixedly connected to a screw 10 that rotates and cooperates between the two side baffles 2. A fixing block 9 that is threadedly engaged with the screw 10 is fixedly connected to the bottom of the slider 6.

[0023] In this embodiment, two adjustment grooves 11 corresponding to the slide rods 3 are provided on the sides of the baffles 2 on both sides. Each of the two sets of opposing inner walls of the adjustment grooves 11 has a limiting groove 12, which are vertically arranged. The adjustment assembly 4 includes two adjustment frames 401 that slide between the two sets of opposing inner walls of the adjustment grooves 11. The two adjustment frames 401 are vertically arranged, and each of the outer walls of the two adjustment frames 401 is fixedly connected to a limiting block 402 that slides with the limiting groove 12. Adjusting blocks 403 are slidably fitted between the inner walls of the frame 401. Displacement blocks 405 are fixedly connected to the two symmetrical outer sides of the adjusting blocks 403. Displacement grooves 404 are opened on the inner walls of the two adjusting frames 401 to slidably fit with the two sets of displacement blocks 405 of the adjusting blocks 403. Fixed studs 406 are fixedly connected to both ends of the slide rod 3 and are provided in the through holes in the middle of the two adjusting blocks 403. Fixed nuts 407 are threaded on the fixed studs 406 and abut against the adjusting blocks 403.

[0024] Specifically, in the adjustment assembly 4, the adjustment frame 401 slides with the limiting groove 12 in the adjustment groove 11 of the baffle 2 via the limiting block 402 on the outer wall, and the two sets of limiting grooves 12 are vertically arranged, which can realize the displacement of the adjustment frame 401 in the horizontal and vertical directions respectively; the adjustment block 403 slides with the displacement groove 404 on the inner wall of the adjustment frame 401 via the displacement block 405, which can further fine-tune the position within the adjustment frame 401. By adjusting the position of the adjustment frame 401 and the adjustment block 403, the fixing studs 406 at both ends of the slide rod 3 can be moved synchronously, realizing the precise positioning of the slide rod 3 in the horizontal and vertical directions. After the adjustment is completed, tighten the fixing nut 407 to fix the adjustment block 403 and the fixing stud 406, ensuring the stability of the slide rod 3.

[0025] In this embodiment, the dust removal assembly 8 includes dust removal rings 801 symmetrically arranged on both sides of the connecting block 7. The dust removal rings 801 are coaxially sleeved around the periphery of the slide rod 3. The inner diameter of the dust removal rings 801 gradually narrows along the direction from the connecting block 7 to the slide rod 3, and tightly fits the surface of the slide rod 3. A scraping block 802 that mates with the surface of the dust removal rings 801 is provided on one side of the connecting block 7. A connecting ring 806 is fixedly connected to one side of the dust removal rings 801. Annular grooves 805 are formed on both sides of the connecting block 7 to rotatably engage with the connecting rings 806. Friction rings are fixedly connected to the periphery of the annular grooves 805. The friction wheel 807 is connected to a fixed frame 803 on one side of the connecting block 7. The inner wall of the fixed frame 803 is slidably fitted with a friction strip 804 that cooperates with the friction wheel 807. A T-shaped groove 808 is provided at the bottom of the connecting block 7. A T-shaped block 809 that slidably cooperates with the T-shaped groove 808 is fixedly connected to one side of the scraping block 802. A spring 810 is fixedly connected between one side of the T-shaped block 809 and the inner wall of the T-shaped groove 808. An abutment post 811 is fixedly connected to the upper side of the T-shaped block 809. The end of the friction strip 804 is provided with a bevel 812 that cooperates with the abutment post 811.

[0026] Specifically, when the slider 6 slides along the slide rod 3, the dust removal rings 801 on both sides of the connecting block 7 are coaxially sleeved around the slide rod 3, and the inner diameter of the dust removal rings 801 gradually contracts along the direction from the connecting block 7 to the slide rod 3, tightly fitting the surface of the slide rod 3, which can initially scrape away dust and debris from the surface of the slide rod 3. At the same time, the dust removal rings 801 are rotatably engaged with the annular groove 805 of the connecting block 7 through the connecting ring 806. During the sliding of the slider, the friction wheel 807 on the periphery of the annular groove 805 generates relative friction with the dust removal ring 801, driving the friction wheel 807 to rotate, thereby pushing the friction strip 804 in the fixed frame 803 to slide. The inclined edge 812 at the end of the friction strip 804 contacts the abutment post 811 on the T-shaped block 809, pushing the T-shaped block 809 to slide along the T-groove 808, so that the scraping block 802 is close to the surface of the dust removal ring 801 to scrape off the impurities attached to the dust removal ring 801; when the friction strip 804 is reset, the T-shaped block 809 drives the scraping block 802 to reset under the elastic force of the spring 810, realizing the automatic cleaning of the dust removal ring and avoiding the accumulation of impurities that affect the dust removal effect.

[0027] When using the device, during the actual operation of the double-support linear guide rail, the position of the slide bar needs to be adjusted according to the equipment assembly requirements and load conditions: First, loosen the fixing nuts 407 on the fixing studs 406 at both ends of the slide bar 3 to release the fixing restriction on the adjusting block 403; then, with the help of the adjusting assembly 4, the adjusting frame 401 is displaced in the horizontal and vertical directions by sliding cooperation between the limiting block 402 on the outer wall of the adjusting frame 401 and the limiting groove 12 vertically set in the adjusting groove 11 of the baffle 2. At the same time, the adjusting block 403 is displaced by the displacement block 4. 05 slides against the displacement groove 404 on the inner wall of the adjustment frame 401 to further fine-tune the position, thereby driving the slide rod 3 to move synchronously to the target position. Finally, tighten the fixing nut 407 to fix the adjustment block 403 to the fixing stud 406, ensuring that the position of the slide rod 3 is stable and the parallelism meets the standard. After the adjustment is completed, start the equipment. The output shaft of the servo motor 5 drives the screw 10, which is rotated between the two side baffles 2, to rotate. Because the fixing block 9 at the bottom of the slider 6 is threaded with the screw 10, and the slider 6 slides with the slide rod 3 through the connecting blocks 7 on both sides of the bottom. The connection converts the rotational motion of the screw 10 into the linear motion of the fixed block 9, thereby driving the slider 6 to reciprocate stably along the slide rod 3, achieving linear transmission. The dust removal rings 801 on both sides of the connecting block 7 are coaxially sleeved around the slide rod 3, with their inner diameter gradually contracting along the direction from the connecting block 7 to the slide rod 3, tightly fitting the surface of the slide rod 3 to initially scrape away dust and debris. Simultaneously, the dust removal rings 801 rotate with the annular groove 805 of the connecting block 7 via the connecting ring 806, and the annular groove 805 rotates around the slider as it slides. The friction wheel 807 generates relative friction with the dust removal ring 801 and rotates, pushing the friction strip 804 in the fixed frame 803 to slide. The inclined edge 812 at the end of the friction strip 804 contacts the abutment post 811 on the T-shaped block 809, pushing the T-shaped block 809 to slide along the T-groove 808, so that the scraping block 802 is close to the surface of the dust removal ring 801 to scrape off the attached impurities. When the friction strip 804 is reset, the T-shaped block 809 drives the scraping block 802 to reset under the elastic force of the spring 810, completing the automatic cleaning of the dust removal ring and ensuring continuous dust removal effect.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
