Description

Technical Field

[0001] This invention relates to the field of linear guide technology, specifically a combined linear guide slider. Background Technology

[0002] Linear guides are the core components for achieving high-precision linear motion in mechanical transmission. They consist of slide rails, sliders, and rolling elements (balls / rollers), and maintain stable guidance under high loads by replacing sliding friction with rolling friction.

[0003] Chinese patent application date: August 1, 2024, publication number: CN118775423B, discloses a combined linear guide slider, including a guide rail and a slide block, the slide block being slidably mounted on the guide rail, and further including: a liquid cavity, the liquid cavity being opened inside the slide block; a liquid outlet, the liquid outlet being opened on the bottom surface of the slide block and communicating with the liquid cavity; a mounting box, the mounting box being fixed to the side of the slide block; and a storage box, the storage box being fixed to the side of the mounting box, the storage box containing lubricant. This invention achieves the automatic extraction and injection of lubricant into the liquid cavity through the periodic adsorption and release of a micro-motor and magnetic blocks. This automated lubrication system does not require frequent manual intervention, improving the convenience and efficiency of operation.

[0004] In this technical solution, the internal balls of the slider are blocked and lubricated. However, in actual operation, when the length of the guide rail is difficult to meet the slider's movement distance, the guide rails need to be spliced ​​together. However, during the splicing process, the position between the guide rails needs to be constantly adjusted to reduce or even eliminate the offset between them and avoid gaps between the ends of the guide rails. This makes the operation of splicing the guide rails more troublesome, so further improvements can be made. Summary of the Invention

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a combined linear guide slider, which has the following beneficial effects: 1. In this combined linear guide slider, when the square insert rotates, it drives the U-shaped slide and the sliding disk to rotate synchronously. The sliding ball slides along the spiral groove, causing the sliding disk, slide rod, and fixed plate to move forward relative to the U-shaped slide. The spring is compressed, thus driving the U-shaped slide to move forward first. The slide column slides along the inclined groove, and the pressure plate is inserted into the clearance window and guide groove. Then, the slide column slides along the straight groove, causing the pressure plate to slide along the clearance window and guide groove until the pressure plate is attached to the inner wall of the front side of the guide groove. Through the elasticity of the spring, the square sleeve has a tendency to move forward, thereby making the ends of the two guide rail bodies fit tightly together. Through the cooperation between the square insert and the square sleeve, misalignment between the guide rail bodies can be avoided, thus achieving the purpose of easy splicing between the guide rail bodies. 2. This combined linear guide slider first aligns the ends of the two guide rail bodies and inserts the square pin into the square sleeve. Using an Allen wrench inserted into the first Allen pin, the drive bevel gear rotates, which in turn drives the ring bevel gear and the square sleeve to rotate, which in turn drives the square sleeve and the square pin to rotate synchronously. This causes the front and rear blocking pins to deflect into receiving groove one and receiving groove two, respectively, avoiding obstruction to the slider body. Thus, the rear and front blocking pins can block the slider body at both ends of the spliced ​​guide rails. At the splicing point of the guide rail bodies, the rear and front blocking pins are housed in receiving groove one and receiving groove two, avoiding obstruction to the slider body. 3. This combined linear guide slider holds the square post at the rear end of the splicing guide and rotates it, causing the rear stop post to deflect into the second receiving groove. Then, the slider body is installed from the rear end of the splicing guide. After releasing the square post, the sliding plate moves backward under the elastic action of the second spring, and the square post and the embedded post are reset. The rear stop post passes out from the second receiving groove and blocks the slider body; thus achieving the purpose of facilitating the installation of the slider body. 4. This combined linear guide slider inserts two L-shaped plates into the slots. An Allen wrench is inserted into the second Allen post, causing the turntable to rotate. The turntable, positioned on the side wall of the second inclined groove, presses against the second sliding post, causing the two L-shaped plates to move back-to-back and engage in the slots. Continuing to rotate the turntable causes the second sliding post to slide into the first arc-shaped groove, maintaining the L-shaped plates engaged. As the second sliding post slides along the second inclined groove, the third sliding post slides along the second arc-shaped groove, keeping the support arm stationary relative to the square cover. As the second sliding post slides along the first arc-shaped groove, the third sliding into the third inclined groove, where the turntable, positioned on the side wall of the third inclined groove, presses against the third sliding post, causing the support arm to slide along the adjustment groove. This adjusts the distance between the ends of the support arms to accommodate different structures or equipment installation spacing. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-2 A combined linear guide slider includes a guide body 100 with a countersunk hole 101 through it. A front connector 200 is rotatably connected to the front end of the guide body 100, and a rear connector 300 is rotatably connected to the rear end of the guide body 100. The guide bodies 100 are connected via the front connector 200 and the rear connector 300. A mating pressure member 400 is provided inside the rear end of the front connector 200, and a rotation limiting member 500 is provided inside the rear end of the front connector 200. The rotation limiting member 500 limits the front connector 200, preventing accidental rotation. When the front connector 200 rotates, it drives the rear connector 300 to rotate synchronously. Through the connecting action of the mating pressure member 400, a tensile force is applied to the front connector 200, causing it to tend to move towards the rear connector 300, thus ensuring a tight connection between the guide bodies 100. A slider body 600 is slidably connected to the guide rail body 100. A support platform 700 is provided on the top of the slider body 600. The support platform 700 and the slider body 600 are connected by a snap-fit ​​assembly 800. An array of spacing adjustment members 900 are slidably connected through the support platform 700. Thus, by sliding the spacing adjustment members 900 relative to the support platform 700, the spacing between the ends of the spacing adjustment members 900 can be adjusted, which facilitates support for structures of different sizes.

[0024] Please see Figures 3-5 The front-end connector 200 includes a square-mouth sleeve 201 with a square opening. A front-end mounting hole 202 is provided at the front end of the guide rail body 100. The diameter of the square-mouth sleeve 201 is equal to the diameter of the front-end mounting hole 202. The square-mouth sleeve 201 is rotatably connected within the front-end mounting hole 202. Four guide grooves 203 are arrayed and penetrated on the outer circumferential surface of the square-mouth sleeve 201. A front stop post 204 is fixedly installed in the middle of the square-mouth sleeve 201. A receiving groove 205 is provided at the top of the guide rail body 100, communicating with the front-end mounting hole 202. The front stop post 204 protrudes from the receiving groove 205. When the slider body 600 slides along the guide rail body 100, the front stop post 204 can block the slider body 600 to prevent it from detaching from the guide rail body 100. This eliminates the need for an end cap at the end of the guide rail body 100, avoiding situations where the end cap is lost and affects the blocking effect on the slider body 600. A rotation drive component is provided at the rear end of the square sleeve 201.

[0025] The rotating drive component includes an annular bevel gear 206 fixedly mounted on the outer wall of the rear end of the square sleeve 201. A drive bevel gear 207 meshes with the upper rear side of the annular bevel gear 206. An internal hexagonal prism 208 is fixedly mounted on the top of the drive bevel gear 207. A through hole 209 is opened on the top of the guide rail body 100. The internal hexagonal prism 208 and the drive bevel gear 207 are rotatably connected in the through hole 209. When splicing the guide rail bodies 100, the rear end connector 300 is inserted into the square sleeve 201, and then an internal hexagonal wrench is inserted into the internal hexagonal prism 208 to drive the drive bevel gear 207 to rotate. This drives the annular bevel gear 206 and the square sleeve 201 to rotate, causing the front stop post 204 to deflect into the receiving groove 205, preventing the front stop post 204 from blocking the sliding block body 600 from sliding in the middle of the assembled guide rail.

[0026] Please see Figure 3 and Figure 6 The rear connector 300 includes a post 301, with a square insert post 302 fixedly installed at the rear end of the post 301. The rear end of the guide rail body 100 has a rear mounting hole 303. The inner diameter of the middle part of the rear mounting hole 303 is equal to the diameter of the post 301, while the inner diameter of the rear half of the rear mounting hole 303 is smaller than the inner diameter of the rear mounting hole 303 and equal to the diameter of the square sleeve 201. The square insert post 302 is fixedly installed at the rear end of the post 301, extending to the outside of the guide rail body 100. The square insert post 302 is inserted into the square sleeve 201, so that when the square sleeve 201 rotates, it can drive the square insert post 302 and the post 301 to rotate.

[0027] A rear stop post 304 is fixedly installed on the circumferential surface of the embedded post 301. A receiving groove 305 is provided at the top of the guide rail body 100, and the rear stop post 304 extends out from the receiving groove 305. Thus, the rear stop post 304 blocks the slider body 600 from the rear end of the guide rail body 100, preventing the slider body 600 from detaching from the rear end of the guide rail body 100. When splicing guide rail bodies 100, the embedded post 301 and the square insert post 302 rotate synchronously with the square sleeve 201, causing the rear stop post 304 to deflect into the receiving groove 305, preventing it from blocking the slider body 600 in the middle of the spliced ​​guide rail. When installing the slider body 600 onto the spliced ​​guide rail, the square insert post 302 can be held and rotated to deflect the rear stop post 304 into the receiving groove 305, avoiding obstruction of the slider body 600, allowing the slider body 600 to be installed from the rear end of the spliced ​​guide rail.

[0028] A rectangular groove 306 is formed through the center of the front end of the insert post 301. The rectangular groove 306 extends to the middle of the square insert post 302. A clearance window 307 is formed in the front half of the square insert post 302, and the clearance window 307 communicates with the rectangular groove 306. The rectangular groove 306 and the clearance window 307 are aligned to accommodate the mating pressure member 400.

[0029] Please see Figure 3 and Figures 7-8 The mating pressure component 400 includes a U-shaped slide plate 401 inserted into a rectangular groove 306. The U-shaped slide plate 401 is U-shaped when viewed from above. Two sliding grooves 402 are formed through the rear half of the U-shaped slide plate 401 on both the left and right sides, and the sliding grooves 402 are arranged along the width direction of the U-shaped slide plate 401. A pressure plate 403 is provided inside the rear end of the U-shaped slide plate 401. Two sliders 404 are fixedly installed on both the left and right sides of the pressure plate 403, and the sliders 404 are slidably connected within the sliding grooves 402. This allows the pressure plate 403 to slide along the width direction of the U-shaped slide plate 401.

[0030] Two sliding pillars 405 are fixedly installed at the ends of the two sliders 404 located behind the pressure plate 403. Two inclined grooves 406 and two straight grooves 407 are opened on the left and right side walls of the rectangular groove 306. The top of the inclined groove 406 is connected to the rear end of the straight groove 407. The sliding pillars 405 are slidably connected in the inclined grooves 406 and the straight grooves 407. An elastic pulling member is provided through the front end of the U-shaped slider 401. When the square sleeve 201 and the square insert 302 rotate, they drive the U-shaped slide 401 to rotate synchronously. During this process, the elastic puller pulls the U-shaped slide 401 forward, so that the slide 405 slides along the inclined groove 406 first, and the pressure plate 403 moves along the width direction of the U-shaped slide 401 and is inserted into the clearance window 307 and the guide groove 203. Then the receiving groove 305 slides along the straight groove 407 until the pressure plate 403 is attached to the inner wall of the front side of the guide groove 203. The elastic puller continues to apply a pulling force to the U-shaped slide 401, increasing the pressure of the pressure plate 403 on the square sleeve 201, so that the square sleeve 201 has a tendency to move forward.

[0031] The elastic pull component includes a sliding disk 408, with a circumferential array of sliding balls 409 fixedly arranged on its surface. A spiral groove 410 is formed in the front half of the rear mounting hole 303, and the sliding balls 409 are slidably connected within the spiral groove 410. Two sliding rods 411 are fixedly installed on the rear side of the sliding disk 408, and a fixing plate 412 is fixedly installed between the rear ends of the two sliding rods 411. The fixing plate 412 is slidably connected within a U-shaped sliding piece 401. A spring 413 is sleeved on the outer side of each sliding rod 411, with both ends of the spring 413 fixedly installed on the rear side of the fixing plate 412 and the inner wall of the front end of the U-shaped sliding piece 401, respectively. Thus, when the U-shaped sliding piece 401 rotates following the square insert 302, it drives the sliding disk 408 to rotate synchronously. Combined with the guiding action of the sliding balls 409 and the spiral groove 410, the sliding disk 408 moves forward while rotating. This causes the slide bar 411 and the fixed plate 412 to move forward relative to the U-shaped slide plate 401, and the spring 413 is compressed, giving the U-shaped slide plate 401 a tendency to move forward.

[0032] A second spring 414 is installed in the front half of the rear mounting hole 303. Washers 415 are fixedly installed at both ends of the second spring 414. Bosses 416 are arrayed on the circumferential surface of the washers 415. Linear grooves 417 are arrayed on the inner wall of the front half of the rear mounting hole 303, and the bosses 416 are slidably connected within the linear grooves 417. Thus, when the sliding disk 408 moves forward, it compresses the second spring 414. The sliding disk 408 rotates relative to the washers 415, but does not cause the washers 415 to rotate, thereby causing the second spring 414 to twist. Through the elasticity of the second spring 414, the sliding disk 408 has a tendency to move backward, causing the rear blocking post 304 to initially protrude from the receiving groove 305, thus blocking the slider body 600.

[0033] Please see Figure 5 The rotation limiting component 500 includes a fixed disk 501 fixedly installed on the inner wall of the rear end of the front mounting hole 202. An array of sliding holes 502 are formed on the circumferential surface of the fixed disk 501. A limiting post 503 is slidably connected within each sliding hole 502. A spring 504 is fixedly installed between one end of the limiting post 503 and the inner wall of the sliding hole 502. The other end of the limiting post 503 is hemispherical. Limiting teeth 505 are fixedly arranged on the inner wall of the rear end of the square sleeve 201. The hemispherical end of the limiting post 503 is abutted between two adjacent limiting teeth 505. Thus, through the elasticity of the spring 504, the limiting post 503 is tightly pressed against the side of the limiting teeth 505, preventing the square sleeve 201 from rotating.

[0034] Please see Figures 9-10 The support platform 700 includes a square cover 701. A straight groove 702 is formed at the bottom of the square cover 701, communicating with the interior of the square cover 701. A turntable 703 is rotatably connected inside the square cover 701. A hexagonal socket 704 is fixedly installed at the center of the top of the turntable 703. Bolts 705 are threaded onto the side of the square cover 701, fitting against the circumference of the turntable 703. An Allen wrench is inserted into the hexagonal socket 704, causing the turntable 703 to rotate. Then, by tightening the bolts 705, the bolts are pressed against the side of the turntable 703, preventing further rotation of the turntable 703.

[0035] Please see Figures 9-11The snap-fit ​​assembly 800 includes two L-shaped plates 801. A slot 601 is provided on the top of the slider body 600, and the L-shaped plates 801 snap into the slot 601. Clamping arms 802 are fixedly installed at both ends of the L-shaped plates 801. Slider 2 803 and slider 3 804 are fixedly installed on the top of the L-shaped plates 801. Slider 2 803 is slidably connected to the bottom of the square cover 701. The cross-section of slider 2 803 is dovetail-shaped. A dovetail groove (not shown) is provided at the bottom of the square cover 701 to mate with slider 2 803. Slider 3 804 is slidably connected through a straight groove 3 702. A sliding column 2 805 is fixedly installed on the top of slider 3 804. An inclined groove 2 806 and an arc-shaped groove 1 807 are arrayed on the bottom of the turntable 703. The inclined groove 2 806 communicates with the arc-shaped groove 1 807, and the center of the arc of the arc-shaped groove 1 807 coincides with the axis of the turntable 703. Thus, when the turntable 703 rotates, the turntable 703, located on the side wall of the inclined groove 806, presses against the sliding column 805, causing the two L-shaped plates 801 to move in opposite directions and engage inside the slot 601. Afterward, the sliding column 805 slides into the arc groove 807, while the L-shaped plates 801 remain engaged inside the slot 601.

[0036] Please see Figures 10-11 The spacing adjustment component 900 includes four support arms 901. Each of the four corners of the square cover 701 has an adjustment groove 903, which is connected to the inside of the square cover 701. One end of the adjustment groove 903 located outside the square cover 701 has a bolt hole 902. The bottom of the support arm 901 located inside the square cover 701 is fixedly installed with a sliding column 904. The top of the turntable 703 has an arc-shaped groove 905 and an inclined groove 906 arranged in an array. The arc-shaped groove 905 and the inclined groove 906 are connected. The center of the arc of the arc-shaped groove 905 coincides with the axis of the turntable 703. The sliding column 904 is slidably connected in the arc-shaped groove 905 and the inclined groove 906.

[0037] Furthermore, when the second sliding column 805 slides from the second inclined groove 806 to the end of the first arc groove 807, the third sliding column 904 remains inside the second arc groove 905. Then, the turntable 703 continues to rotate, causing the third sliding column 904 to move into the third inclined groove 906. The turntable 703, positioned on the side wall of the third inclined groove 906, presses against the third sliding column 904, causing the support arm 901 to slide outward along the adjusting groove 903, thus adjusting the distance between the ends of the support arms 901.

[0038] In use, first align the ends of the two guide rail bodies 100, and insert the square pin 302 into the square sleeve 201. Use an Allen wrench to insert into the Allen pin 208 to drive the drive bevel gear 207 to rotate, which in turn drives the ring bevel gear 206 and the square sleeve 201 to rotate, which in turn drives the square sleeve 201 and the square pin 302 to rotate synchronously, so that the front blocking pin 204 and the rear blocking pin 304 are deflected into the receiving groove 205 and the receiving groove 305 respectively, so as to avoid obstructing the slider body 600. When the square insert 302 rotates, it drives the U-shaped slide 401 and the sliding disk 408 to rotate synchronously. The ball 409 slides along the spiral groove 410, causing the sliding disk 408, the slide rod 411 and the fixed plate 412 to move forward relative to the U-shaped slide 401. The spring 413 is compressed, thereby driving the U-shaped slide 401 to move forward first. The slide column 405 slides along the inclined groove 406. The pressure plate 403 is inserted into the clearance window 307 and the guide groove 203. Then, the slide column 405 slides along the straight groove 407, causing the pressure plate 403 to slide along the clearance window 307 and the guide groove 203 until the pressure plate 403 is attached to the inner wall of the front side of the guide groove 203. Through the elasticity of the spring 413, the square sleeve 201 has a tendency to move forward, thereby making the ends of the two guide rail bodies 100 fit tightly together. Hold the square insert 302 at the rear end of the splicing guide rail and rotate it so that the rear blocking post 304 deflects into the receiving groove 305. Then install the slider body 600 from the rear end of the splicing guide rail. After releasing the square insert 302, under the elastic action of the spring 414, the sliding disk 408 moves backward and the square insert 302 and the embedded post 301 are reset. The rear blocking post 304 passes out from the receiving groove 305 and blocks the slider body 600. Insert two L-shaped plates 801 into the slot 601. Use an Allen wrench to insert into the Allen post 704 to drive the turntable 703 to rotate. The turntable 703 is located on the side wall of the inclined groove 806 and presses the sliding post 805, causing the two L-shaped plates 801 to move in opposite directions and engage with the slot 601. Continue to rotate the turntable 703 to slide the sliding post 805 into the arc groove 807, keeping the L-shaped plates 801 engaged with the slot 601. When the second sliding column 805 slides along the second inclined groove 806, the third sliding column 904 slides along the second arc groove 905. The support arm 901 remains stationary relative to the square cover 701. When the second sliding column 805 slides along the first arc groove 807, the third sliding column 904 slides into the interior of the third inclined groove 906. The turntable 703 is located on the side wall of the third inclined groove 906 and presses the third sliding column 904, causing the support arm 901 to slide along the adjustment groove 903, adjusting the distance between the ends of the support arms 901 to adapt to the installation distance of different structures or equipment.
