Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, and in particular to a linear guide with a cleanup function. Background Technology

[0002] Linear guides are mechanical transmission components, which can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are mainly used in high-precision or high-speed linear reciprocating motion applications and can withstand a certain amount of torque, enabling high-precision linear motion under high load conditions.

[0003] Currently, in high-dust processing environments, the workpieces generate a large amount of dust and impurities during processing. These dust and impurities accumulate on the guide rail surface over time, significantly impacting the equipment's machining accuracy. Furthermore, some corrosive dust (such as corrosive particles formed after the oxidation of zinc, copper, and lead) can create pitting on the guide rail surface, shortening the equipment's lifespan. Traditional ball bearing guides typically have sealed end caps and sealing plates to block dust and impurities. However, dust particles are extremely fine and easily accumulate at the guide rail joints after prolonged processing. The sealed end caps and sealing plates cannot completely remove the dust. Since the balls are in direct contact with the guide rail surface, once dust and impurities enter the slider, they mix with the lubricating grease to form abrasive compounds, increasing the resistance and wear at the ball-guide rail contact surface. This makes it difficult for the balls to operate normally, leading to slider jamming, guide rail damage, and making manual cleaning and maintenance difficult. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to propose a linear guide rail with a dust removal function. By using the rolling of rollers, the influence of dust is greatly reduced. At the same time, the dust removal mechanism can continuously clean the surface of the guide rail and rollers during equipment operation, ensuring high guiding accuracy and good motion stability.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a linear guide rail with a cleaning function, comprising: a guide rail, a slider, multiple rollers, multiple sets of connecting mechanisms, and a cleaning mechanism, wherein the slider is adapted to the guide rail; the slider has multiple through holes and multiple mounting holes respectively; the multiple rollers are respectively connected to the slider through corresponding connecting mechanisms, and the rollers are adapted to the guide rail; the cleaning mechanism includes two first cleaning parts and two second cleaning parts, wherein the two first cleaning parts are respectively disposed at the front end and rear end of the slider, and the first cleaning parts are used to clean the guide rail; the two second cleaning parts are respectively disposed on both sides of the slider, and the second cleaning parts are used to clean the rollers.

[0007] In addition, the linear guide rail with impurity removal function proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the connecting mechanism includes a sealed bearing, a positioning screw, a washer, and a nut. The sealed bearing is disposed inside the roller. The positioning screw is connected to the sealed bearing and its upper end extends into the corresponding through hole. The washer is connected to the positioning screw and is located between the sealed bearing and the slider. The nut is threadedly connected to the positioning screw and is located inside the through hole.

[0009] Specifically, each of the first cleaning sections includes a rubber pad, a metal scraper, and two screws, wherein the rubber pad is attached to one end of the slider; the metal scraper is attached to the rubber pad and adapted to the guide rail; and the two screws pass through the rubber pad and the metal scraper respectively and are threadedly connected to the slider.

[0010] Specifically, slots are provided on both sides of the slider.

[0011] Specifically, each of the second cleaning units includes a connecting plate, two sponge blocks, two brushes, and a hand-tightening bolt. The connecting plate is snapped into the slot. The two sponge blocks are respectively connected to the connecting plate and respectively abut against the surface of the corresponding roller. The two brushes are respectively connected to the connecting plate and respectively abut against the surface of the corresponding roller. The hand-tightening bolt passes through the connecting plate and is threaded onto the slider.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The linear guide rail with the impurity removal function of the present invention moves the slider by means of the rolling of the rollers, without the need for lubricating oil. Therefore, it will not mix with dust to produce abrasive compounds, and thus will not generate great resistance, thereby greatly reducing the impact of dust. At the same time, the impurity removal mechanism can continuously clean the surface of the guide rail and rollers during the operation of the equipment, sweeping away the dust and debris attached to the surface, reducing the wear, vibration and noise of the guide rail, and ensuring high guiding accuracy and good motion stability.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The following describes an embodiment of the linear guide rail with impurity removal function, with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the linear guide rail with impurity removal function in this embodiment of the present invention may include: a guide rail 1, a slider 2, multiple rollers 3, multiple sets of connecting mechanisms 4, and an impurity removal mechanism 5.

[0023] The slider 2 is adapted to the guide rail 1.

[0024] The slider 2 has multiple through holes 201 and multiple mounting holes 202 inside.

[0025] It should be noted that the slider 2 and guide rail 1 described in this embodiment are both made of stainless steel, which has high load-bearing capacity and strong resistance to rust and corrosion. The through hole 201 and the mounting hole 202 are located at the four corners of the slider 2, and the mounting hole 202 is used to connect with external processing equipment.

[0026] Multiple rollers 3 are connected to sliders 2 through corresponding connecting mechanisms 4, and rollers 3 are adapted to guide rails 1.

[0027] It should be noted that the roller 3 described in this embodiment is made of stainless steel, which has high load-bearing capacity, strong rust and corrosion resistance, and can fit into the grooves on both sides of the guide rail 1 to support the slider 2. The slider 2 does not contact the guide rail 1 to reduce friction. The roller 3 is rotatably connected to the connecting mechanism 4. By rolling the roller 3 in the guide rail 1, the slider 2 is driven to move linearly along the guide rail 1.

[0028] Understandably, since roller 3 is relatively large and does not require lubrication during operation, it will not mix with dust to produce abrasive compounds, thus avoiding significant resistance and greatly reducing the likelihood of slider 2 getting stuck and damaged.

[0029] The cleaning mechanism 5 includes two first cleaning sections 501 and two second cleaning sections 502.

[0030] Two first cleaning parts 501 are respectively disposed at the front and rear ends of the slider 2. The first cleaning parts 501 are used to clean the guide rail 1. Two second cleaning parts 502 are respectively disposed on both sides of the slider 2. The second cleaning parts 502 are used to clean the roller 3.

[0031] Specifically, in high-dust processing environments such as wood cutting and polishing, linear guides with impurity removal functions are used to support and precisely guide the processing equipment.

[0032] After the relevant personnel install the processing equipment onto the slider 2 through the mounting hole 202, the processing equipment can be controlled by the processing center to cut or polish the wood. As the slider 2 moves, the first cleaning part 501 scrapes off the dust and debris adhering to the guide rail 1 by adhering to the surface of the guide rail 1, while the second cleaning part 502 sweeps off the dust and debris adhering to it as the roller 3 rotates, thereby keeping the contact surface between the roller 3 and the guide rail 1 smooth and flat, reducing vibration and noise, and improving the guiding accuracy and movement stability of the slider 2.

[0033] In one embodiment of this utility model, such as Figure 2 As shown, the connecting mechanism 4 includes a sealed bearing 401, a positioning screw 402, a washer 403, and a nut 404.

[0034] The sealed bearing 401 is located inside the roller 3. The positioning screw 402 is connected to the sealed bearing 401 and its upper end extends into the corresponding through hole 201. The gasket 403 is connected to the positioning screw 402 and is located between the sealed bearing 401 and the slider 2. The nut 404 is threadedly connected to the positioning screw 402 and is located inside the through hole 201.

[0035] Understandably, the sealed bearing 401 has good waterproof and dustproof performance, which allows the roller 3 to rotate smoothly in a high dust environment. The washer 403 is welded and fixed to the positioning screw 402. The nut 404 cooperates with the washer 403 to fix the positioning screw 402 inside the through hole 201, thereby maintaining the stability of the roller 3.

[0036] In one embodiment of this utility model, such as Figure 3 As shown, each first cleaning part 501 includes a rubber pad 5011, a metal scraper 5012, and two screws 5013.

[0037] Among them, the rubber pad 5011 is attached to one end of the slider 2, the metal scraper 5012 is attached to the rubber pad 5011 and is adapted to the guide rail 1, and the two screws 5013 pass through the rubber pad 5011 and the metal scraper 5012 respectively and are threaded to the slider 2.

[0038] It should be noted that the slider 2 described in this embodiment has a first threaded hole at the corresponding screw 5013. The metal scraper 5012 is made of stainless steel, which has high strength, is not easily deformed, has strong rust and corrosion resistance, and fits into the upper surface and the grooves on both sides of the guide rail 1.

[0039] Specifically, in a high-dust processing environment, the slider 2 guides the movement of the processing equipment, and the metal scraper 5012 scrapes away the dust and debris that fall and adhere to the surface of the guide rail 1, ensuring that the guide rail 1 is smooth and flat.

[0040] It should be noted that, as a possible scenario, in a dust-free processing environment, the metal scraper 5012 and the rubber pad 5011 can be quickly removed by turning the screw 5013 to reduce the wear of the guide rail 1.

[0041] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, slots 6 are provided on both sides of the slider 2.

[0042] Each second cleaning section 502 includes a connecting plate 5021, two sponge blocks 5022, two brushes 5023, and a hand-tightening bolt 5024.

[0043] The connecting plate 5021 is snapped into the slot 6. Two sponge blocks 5022 are connected to the connecting plate 5021 and are respectively attached to the surface of the corresponding roller 3. Two brushes 5023 are connected to the connecting plate 5021 and are respectively attached to the surface of the corresponding roller 3. The hand-tightening bolt 5024 passes through the connecting plate 5021 and is threadedly connected to the slider 2.

[0044] It should be noted that the sponge block 5022 and brush 5023 described in this embodiment are arranged side by side, and both have openings that are adapted to the shape of the roller 3, so as to ensure the cleaning effect without causing too much resistance to the roller 3.

[0045] Specifically, in a high-dust processing environment, the slider 2 guides the movement of the processing equipment. As the roller 3 rolls, the brush 5023 removes large particles of debris and impurities attached to the roller 3, while the sponge block 5022 wipes away fine dust that the brush 5023 cannot clean, thus keeping the roller 3 smooth and flat at all times.

[0046] Understandably, the connecting plate 5021 can be quickly disassembled and assembled by hand-tightening bolt 5024, thus facilitating the convenient and quick replacement of new sponge blocks 5022 and brushes 5023 by relevant personnel after processing.

[0047] In summary, the linear guide rail with a dust removal function of this utility model achieves the movement of the slider by the rolling of rollers, eliminating the need for lubricating oil and greatly reducing the impact of dust. At the same time, the dust removal mechanism can continuously clean the surface of the guide rail and rollers during equipment operation, sweeping away the dust and debris attached to their surfaces, reducing wear, vibration and noise of the guide rail, and ensuring high guiding accuracy and good motion stability.
