Description

Technical Field

[0001] This utility model relates to the field of slide table technology, and in particular to a linear slide table that prevents dust accumulation. Background Technology

[0002] A linear slide is a precision mechanical component consisting of a guide rail, a slider, a drive mechanism, and a control system. Its core function is to convert the rotational motion of a motor into the high-precision linear motion of the slider along the guide rail. It is widely used in industrial automation, laser processing, precision measurement, and other fields. It achieves low-friction and high-stability displacement control through a ball bearing circulation system or synchronous belt drive. The dust-proof linear slide is an improved product designed for dusty environments such as processing workshops and foundries. It adds a dustproof and dust removal structure to the traditional linear slide to prevent dust, metal shavings, and other foreign objects from entering the gap between the guide rail and the slider, avoiding component wear or movement jamming, and ensuring the operating accuracy and service life of the slide in harsh environments.

[0003] However, in the existing technology, the suction range of the fixed suction component is limited, and the position of the suction port is difficult to match the movement trajectory of the slider precisely, resulting in uneven suction process. Dust accumulation dead corners are easily formed in the edge area of ​​the slider movement and the gap of the guide rail groove, making it difficult to completely clean local dust accumulation. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a linear slide table that prevents dust accumulation, aiming to improve the problem in the prior art where the dust collection range of the fixed dust collection component is limited, resulting in uneven dust collection.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A dust-proof linear slide includes a base, with the linear slide and an inverted U-shaped plate fixedly connected to the top of the base. The U-shaped plate spans over the linear slide, and two first limiting blocks are fixed to the lower top surface of the U-shaped plate. A limiting plate is fixed between the two first limiting blocks, and a dust-collecting mechanism that can reciprocate along the length of the linear slide is provided on the limiting plate. A protective cover mechanism for covering the linear slide is also slidably connected to the base.

[0006] The following are further optimizations of the above technical solution by this utility model: The dust collection mechanism includes a slide groove opened in the limiting plate. A strip-shaped movable groove is opened at the bottom of the slide groove along its length direction. A first slider is slidably connected in the slide groove. A fixed block is fixedly connected to the bottom of the first slider. The fixed block extends through the movable groove to the bottom of the limiting plate and is in clearance fit with the movable groove. A dust collection component is fixedly installed at the bottom end of the fixed block. A drive component for driving its reciprocating motion is provided at the top of the first slider.

[0007] Further optimization: The vacuuming component includes a hollow box fixed to the bottom of the fixed block. Multiple suction heads arranged in a matrix are fixedly connected to the lower surface of the hollow box. A collection box and a fan are fixedly connected to the upper surface of the hollow box. The input end of the fan is connected to the internal cavity of the hollow box, and its output end is connected to the collection box.

[0008] Further optimization: The drive assembly includes a rack fixedly installed on the top of the first slider. Two half-gears are symmetrically arranged on both sides of the rack and mesh with it. The teeth of the two half-gears alternately mesh with the rack during rotation. Each half-gear is coaxially fixedly fitted with a transmission rod. The top end of the transmission rod is rotatably connected to the inner side wall of the U-shaped plate through a bearing. A first gear is fixedly fitted on the outer wall of each transmission rod. A motor is fixedly installed on the top surface of the U-shaped plate. The output end of the motor passes through the U-shaped plate and is fixedly connected to a second gear. The second gear meshes with both first gears simultaneously.

[0009] Further optimization: The tooth surface radius of each half gear is 180°.

[0010] Further optimization: The protective cover mechanism includes a first protective cover and a second protective cover. Guide blocks are provided on both sides of the bottom of the first and second protective covers. Guide grooves that are adapted to the guide blocks and extend along the length of the linear slide are correspondingly provided on the base. Two locking structures are symmetrically provided between the first and second protective covers along the width of the linear slide.

[0011] Further optimization: The locking structure includes a second limiting block integrally formed in the middle of the side wall of the first protective cover near the second protective cover, and a limiting groove opened in the middle of the side wall of the second protective cover near the first protective cover. The second limiting block is adapted to the limiting groove, and a slot is opened through the second limiting block along the sliding direction perpendicular to the first protective cover.

[0012] Further optimization: A limiting box is fixed on the outer side wall of the second protective cover near the limiting groove. A second slider is slidably arranged inside the limiting box. A short column is fixedly sleeved inside the second slider. One end of the short column extends into the limiting groove and is adapted to the slot. The other end passes through the limiting box and is fixedly connected to a pull block. A spring is sleeved on the outer side wall of the short column. The two ends of the spring are fixed to the inner side wall of the limiting box and the side wall of the second slider, respectively. The spring is always in a compressed state.

[0013] This utility model features a dual protection design that combines an active dust collection mechanism with a passive dust prevention mechanism, effectively solving the problem of dust accumulation in traditional linear slides and ensuring the slide's motion accuracy and service life. Meanwhile, the protective cover employs a sliding opening and closing structure for convenient operation, a stable and reliable locking structure, and a reciprocating motion design of the dust collection components to ensure comprehensive dust collection coverage. The overall structure is rationally designed and highly practical.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1 to 8 A dust-proof linear slide includes a base 1, which serves as the mounting base for the entire device and is made of high-strength aluminum alloy.

[0021] Please see Figure 2 The top of the base 1 is fixedly connected to the linear slide 2 and the U-shaped plate 3 by bolts. The U-shaped plate 3 has an inverted U-shaped structure and is positioned above the linear slide 2. Both ends of the U-shaped plate 3 are fixed to the top sides of the base 1 respectively.

[0022] Please see Figure 2 and Figure 6 Two first limiting blocks 4 are fixed to the top lower surface of the U-shaped plate 3 by welding intervals. A limiting plate 5 is fixedly connected between the two first limiting blocks 4 by bolts. The limiting plate 5 is a cuboid structure, and its length direction is consistent with the length direction of the linear slide table 2. A dust collection mechanism is provided on the limiting plate 5. The dust collection mechanism can reciprocate along the length direction of the linear slide table 2 to achieve comprehensive dust collection of the guide rail surface of the linear slide table 2.

[0023] Please see Figures 2 to 6 The mechanism includes a slide groove formed within a limiting plate 5. A strip-shaped movable groove is formed along the length of the bottom of the slide groove, the width of which is smaller than the width of the slide groove. A first slider 6 is slidably connected within the slide groove. The cross-section of the first slider 6 is adapted to the slide groove to ensure smooth, uninterrupted sliding.

[0024] The bottom of the first slider 6 is fixedly connected to a fixing block 8 by bolts. The other end of the fixing block 8 passes through the movable groove and extends to the bottom of the limiting plate 5. The fixing block 8 and the movable groove are fitted with a clearance to avoid motion interference.

[0025] A dust collection component is fixedly installed at the bottom of the fixing block 8. The dust collection component includes a hollow box 9, which is fixed to the bottom of the fixing block 8 by bolts. The interior of the hollow box 9 is a cavity structure.

[0026] Multiple suction heads 10 are fixedly connected to the lower surface of the hollow box 9. The multiple suction heads 10 are arranged in a matrix, and each suction head 10 has a different orientation, ensuring that the guide rail surface of the linear slide 2, including the side and top surfaces of the guide rail, can be fully covered.

[0027] The suction head 10 is made of elastic rubber material, which has a certain deformation ability to avoid wear caused by hard contact with the slide guide rail. At the same time, the lower surface of the suction head 10 has several dust suction holes, which are evenly distributed to improve dust suction efficiency.

[0028] The upper surface of the hollow box 9 is fixedly connected to the receiving box 11 and the fan 12 by bolts. The fan 12 is a miniature negative pressure fan. Its input end is connected to the internal cavity of the hollow box 9 through a corrosion-resistant hose, and its output end is connected to the receiving box 11 through the same hose. The receiving box 11 has a top-openable structure, which facilitates the subsequent cleaning of the collected dust.

[0029] To drive the first slider 6 to reciprocate the vacuuming component, a drive component is provided on the top of the first slider 6.

[0030] The drive assembly includes a rack 7 fixedly mounted on the top of the first slider 6, with the length direction of the rack 7 aligned with the slide groove.

[0031] On both sides of the rack 7, two half gears 13 are symmetrically arranged and mesh with the rack 7. The tooth surface arc of each half gear 13 is 180°, and the teeth of the two half gears 13 alternately mesh with the rack 7 during rotation. That is, when the tooth surface of one half gear 13 meshes with the rack 7, the toothless surface of the other half gear 13 is exactly opposite to the rack 7.

[0032] Each half gear 13 is coaxially fixedly connected to a transmission rod 14 via a flat key. The top end of the transmission rod 14 is rotatably connected to the inner side wall of the U-shaped plate 3 via a bearing to ensure smooth rotation.

[0033] Each transmission rod 14 has a first gear 15 fixedly fitted on its outer wall by a flat key.

[0034] A motor 16 is fixedly mounted on the top surface of the U-shaped plate 3 via a motor mount. The output end of the motor 16 passes through the top of the U-shaped plate and is fixedly connected to a second gear 17.

[0035] The second gear 17 simultaneously meshes with the two first gears 15, thereby synchronously transmitting the power of the motor 16 to the two transmission rods 14.

[0036] During operation, the motor 16 drives the second gear 17 to rotate, and the second gear 17 drives the two first gears 15 and the transmission rod 14 that mesh with it to rotate synchronously, thereby driving the half gear 13 to rotate. Since the tooth surfaces of the two half gears 13 are in opposite phase, when one half gear 13 meshes with the rack 7, it pushes the rack 7 to move in one direction. When the toothless surface of the half gear 13 turns towards the rack 7, the tooth surface of the other half gear 13 just meshes with the rack 7, pushing the rack 7 to move in the opposite direction, thereby realizing the reciprocating linear motion of the first slider 6, driving the dust collection component to reciprocate and collect dust along the length of the linear slide 2.

[0037] Please see Figures 7 to 8A protective cover mechanism is also slidably connected to the base 1 to cover the linear slide 2 when the slide is not in operation, preventing dust from falling in. The protective cover mechanism includes a first protective cover 18 and a second protective cover 19, both of which are made of transparent PC material for easy observation of the slide's status.

[0038] The bottom sides of the first protective cover 18 and the second protective cover 19 are integrally formed with guide blocks. The base 1 is provided with guide grooves that are adapted to the guide blocks. The guide grooves extend along the length of the linear slide 2, so that the first protective cover 18 and the second protective cover 19 can slide along the guide grooves to cover the linear slide 2. The two cover the linear slide 2 and close to each other or expose each other and open away from each other.

[0039] Two locking structures are symmetrically provided between the first protective cover 18 and the second protective cover 19 along the width direction of the linear slide (2) to lock them when they are closed, so as to prevent accidental sliding.

[0040] The locking structure includes a second limiting block 20 and a limiting groove 21. The second limiting block 20 is integrally formed in the middle of the side wall of the first protective cover 18 near the second protective cover 19. The limiting groove 21 is opened in the middle of the side wall of the second protective cover 19 near the first protective cover 18. The shape and size of the second limiting block 20 are adapted to the limiting groove 21. A slot is opened through the second limiting block 20 along the sliding direction perpendicular to the sliding direction.

[0041] A limiting box 22 is fixed to the outer wall of the second protective cover 19 near the limiting groove 21 by bolts. The limiting box 22 is a hollow cuboid structure. A second slider 23 is slidably arranged inside the limiting box 22. The cross-section of the second slider 23 is adapted to the internal cavity of the limiting box 22.

[0042] A short column 25 is fixedly sleeved inside the second slider 23. The axis of the short column 25 is perpendicular to the sliding direction of the first protective cover 18. One end of the short column 25 passes through the side wall of the second protective cover 19 and extends into the limiting groove 21. The shape and size of this end are adapted to the slot on the second limiting block 20.

[0043] The other end of the short column 25 passes through the outer wall of the limiting box 22 and is fixedly connected to the pull block 26 by bolts.

[0044] A spring 24 is fitted on the outer side wall of the short column 25. The spring 24 is a compression spring, and its two ends are welded and fixed to the inner side wall of the limiting box 22 and the side wall of the second slider 23, respectively.

[0045] In its natural state, the elastic restoring force of the spring 24 pushes the second slider 23 to move closer to the limiting groove 21, thereby causing the short column 25 to be inserted into the slot of the second limiting block 20, thus locking the first protective cover 18 and the second protective cover 19.

[0046] When the protective cover needs to be opened, pull the pull block 26 outward. The pull block 26 drives the short column 25 and the second slider 23 to move away from the limiting groove 21. The spring 24 is further compressed, and the short column 25 is dislodged from the slot and unlocked. At this time, the first protective cover 18 and the second protective cover 19 can be pushed away from each other.

[0047] All parts in this embodiment are standard parts, common parts, or components that can be manufactured by conventional machining / welding processes. Their specific structures, specifications, and performance parameters are well known to those skilled in the art, and can be selected and designed according to actual engineering needs.

[0048] The working principle of this utility model is as follows: When the linear slide 2 is working, the pull block 26 is pulled to release the protective cover lock, and the first protective cover 18 and the second protective cover 19 are slid open to both sides to expose the linear slide 2.

[0049] When the linear slide 2 stops working, the motor 16 and the fan 12 are started. The motor 16 drives the half gear 13 to rotate through the gear transmission, which in turn drives the rack 7 and the first slider 6 to reciprocate. The dust collection component reciprocates along the length of the linear slide 2 with the first slider 6. The fan 12 generates negative pressure, which sucks the dust on the guide rail surface of the linear slide 2 into the hollow box 9 through the dust collection hole of the suction head 10, and then transports it to the collection box 11 for collection through the pipe.

[0050] After vacuuming is finished, turn off the motor 16 and the fan 12, slide the first protective cover 18 and the second protective cover 19 towards the middle, so that the second limiting block 20 is inserted into the limiting groove 21, and the short column 25 is inserted into the slot under the action of the spring 24 to lock it. The protective cover seals and protects the linear slide 2 to prevent dust from getting in.

[0051] 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.
