Description

Technical Field

[0001] The invention relates to the technical field of linear modules, in particular to a linear motion module. Background Art

[0002] The linear motion module is a mechanical device that can convert the rotational motion of an electric motor into linear motion. It is widely used in automated production equipment, CNC machine tools, 3D printers, robots and other fields, and plays a key role in industrial manufacturing. It is mainly composed of guide rails, sliders, screws, motors and various connectors.

[0003] However, the traditional linear motion module installs the upper cover by bolts, and the installation and disassembly methods are cumbersome and complicated, which consumes a lot of time of maintenance personnel and leads to low maintenance efficiency. In addition, the thread wear of the bolts and the end cover is prone to occur after long-term use, which makes the connection loose and cannot ensure that the upper cover is stably installed on the end cover, affecting the protection effect of internal components. After lubricating the guide rail and the first screw rod of the linear motion module, excess lubricating oil drips directly on the bottom of the base. The large amount of lubricating oil dripping makes the inside of the base greasy, which increases the difficulty of inspecting and maintaining the base and related components. The accumulation of oil leads to corrosion and damage of components, shortening the service life of the equipment. The slider in the guide structure of the linear motion module is easy to fit too tightly with the guide rail due to the thermal expansion effect during the operation of the equipment. Too tight fit will cause the slider to encounter greater resistance when sliding on the guide rail, resulting in jamming and stagnation during movement, and smooth linear movement cannot be achieved.

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, a linear motion module described in the present invention includes a base 1, a carrying structure 2 installed on the base 1, a guide structure 4 installed in the carrying structure 2, a collecting structure 3 installed on the base 1, an upper cover 7 detachably connected to the carrying structure 2, and a mounting structure 6 installed in the upper cover 7; the carrying structure 2 includes two guide rails 201 installed in the base 1 and a mounting seat 202 installed on the base 1, and two end covers 203 are installed on the base 1, and one of the end covers 203 is rotatably connected to the mounting seat 202 by a first The screw rod 204 is slidably connected to a slide seat 206 on the base 1, the slide seat 206 is threadedly connected to the first screw rod 204, the slide seat 206 is slidably connected to a slide rod 207, and the bottom of the slide rod 207 is fixedly connected to a rack 208; the collecting structure 3 includes a collecting frame 301 installed on the base 1 and a plurality of first rotating shafts 302 rotatably connected to the collecting frame 301, a gear 303 is fixedly connected to the first rotating shaft 302, the rack 208 is meshed with one of the gears 303, and a stirring rod 304 is fixedly connected to the first rotating shaft 302.

[0037] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig.10 and Fig.11As shown, a motor 205 is installed on one of the end covers 203, the first screw rod 204 is connected to the output shaft of the motor 205 through a coupling, a slide plate 209 is fixedly connected to the slide bar 207, the slide plate 209 is slidably connected to the slide seat 206, a second screw rod 210 is rotatably connected to the slide seat 206, the slide plate 209 is threadedly connected to the second screw rod 210, a connecting shaft 305 is rotatably connected to the base 1, an iron block 306 is rotatably connected to the connecting shaft 305, a magnetic block 307 is fixedly connected to the base 1, the iron block 306 is adsorbed on the magnetic block 307, and a magnetic block 307 is fixedly connected to the base 1. A carrying block 308 is connected. After lubricating the guide rail 201 and the first screw rod 204, excess lubricating oil will drip into the collection frame 301. The lubricating oil is collected by the collection frame 301 to prevent the lubricating oil from dripping to the bottom of the base 1, making the base 1 greasy and increasing the difficulty of inspecting and maintaining the base and related components. At the same time, by starting the motor 205, the output shaft of the motor 205 rotates to drive the first screw rod 204 to rotate. When the first screw rod 204 rotates, the thread drives the slide 206 to slide. When the slide 206 slides, the rack 208 drives the gear 303 to rotate, so that the gear 303 drives the first rotating shaft 302 to rotate. The first rotating shaft 302 The stirring rod 304 is driven to rotate. When the stirring rod 304 rotates, the lubricating oil collected in the collecting frame 301 can be properly stirred. Proper stirring makes the contact between the lubricating oil and the air more uniform, avoids excessive oxidation of local areas due to long-term contact with the air, and also enables additives such as antioxidants to play a better role, slows down the overall oxidation rate to a certain extent, maintains the good quality of the lubricating oil, and is conducive to subsequent storage and reuse. When the collecting frame 301 needs to be pulled out of the base 1, first insert the second screw rod 210 with the hexagonal wrench, rotate the second screw rod 210, and the second screw rod 210 thread drives the slide plate 209 to slide upward, and the slide plate 20 9 slides upward to drive the slide bar 207 to move upward, and the slide bar 207 drives the rack 208 to move upward. When the rack 208 moves upward to a certain distance, it will not hinder the sliding out of the collection frame 301. At this time, the iron block 306 is rotated so that it is no longer adsorbed with the magnetic block 307. When the iron block 306 is adsorbed with the magnetic block 307, the stability of the iron block 306 can be improved. At the same time, the iron block 306 can resist and limit the collection frame 301 to prevent the collection frame 301 from sliding out and enhance stability. After the iron block 306 is rotated to the mounting block 308, the collection frame 301 can be slid out of the base 1 for subsequent treatment of the collected lubricating oil.

[0038] Specifically, Figure 4 , Figure 5 and Figure 6As shown, the guide structure 4 includes two mounting frames 401 fixedly connected to the bottom of the slide 206 and two mounting rods 402 slidably connected to the mounting frames 401, the mounting rods 402 are fixedly connected with sliders 403, and every two sliders 403 are slidably matched with a guide rail 201, and the mounting rods 402 are rotatably connected with a driving shaft 404, and the mounting frame 401 is rotatably connected with a connecting disk 405, and the connecting disk 405 is provided with a driving groove 406, and the driving shaft 404 is rolling matched with the driving groove 406, and the connecting disk 405 is fixedly connected with a second rotating shaft 407, and the second rotating shaft 407 is rotatably connected to the mounting frame 401, and the guide rods are fixedly connected to the mounting frame 401. 408, the mounting rod 402 is slidably connected to the guide rod 408, the second rotating shaft 407 and the mounting frame 401 are fixed by a limiting structure 5, the limiting structure 5 includes two connecting blocks 501 slidably connected to the second rotating shaft 407 and a limiting rod 502 fixedly connected to the connecting block 501, a plurality of limiting holes 503 are provided on the sliding seat 206, and the plurality of limiting holes 503 are arranged in a circular array about the center of the second rotating shaft 407, the two limiting rods 502 are respectively engaged with two of the limiting holes 503, a first pressing block 504 is fixedly connected between the two connecting blocks 501, the first pressing block 504 is slidably connected to the second rotating shaft 407, and the first pressing block 504 is fixedly connected to the second rotating shaft A first spring 505 is fixedly connected between the slider 403 and the guide rail 201, and a through hole 506 is provided on the slide seat 206. At the same time, when the slider 403 and the guide rail 201 are too tight, a hexagonal wrench is used to pass through the through hole 506, and then the first pressing block 504 is pressed to make it move downward. In this process, the first spring 505 is compressed by the pressure, and at the same time, the first pressing block 504 drives the connecting block 501 and the limiting rod 502 to move downward synchronously until the limiting rod 502 is no longer engaged with the limiting hole 503. At this time, the second rotating shaft 407 is rotated, and the rotation of the second rotating shaft 407 will drive the driving shaft 404 to roll in the driving groove 406. Since the driving groove 406 is elliptical, the driving shaft 404 can simultaneously drive the two mounting rods 402 to move toward or away from each other. When the mounting rod 402 slides, the guide rod 408 and the mounting rod 402 slide in cooperation, ensuring the smooth sliding of the mounting rod 402 and avoiding problems such as jamming and deviation caused by unstable sliding. At the same time, the mounting rod 402 drives the two sliders 403 to move. In this way, the slider 403 realizes sliding adjustment. This adjustment method can avoid the slider 403 and the guide rail 201 from being too tight due to thermal expansion, preventing the sliding from being smooth, and avoiding the guide rail 201 from being too tight and sliding smoothly, thereby increasing the friction between the two, thereby aggravating the degree of wear and seriously affecting their service life. Through timely adjustment, the slider 403 and the guide rail 201 can maintain a suitable gap to ensure stable operation of the equipment.When the sliding adjustment of the slider 403 is completed, just pull out the hexagonal wrench, and the first spring 505 will restore its deformation, pushing the limit rod 502 to move upward, so that it re-engages with the limit hole 503. The engagement of the limit rod 502 with the limit hole 503 can effectively limit the rotation of the second rotating shaft 407 and the connecting disk 405 after rotation, preventing the position of the slider 403 from changing due to accidental rotation, and ensuring that the equipment always maintains a good working condition during subsequent operation.

[0039] Specifically, Figure 1 , Figure 7 , Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, the mounting structure 6 includes two mounting plates 601 slidably connected to the upper cover 7 and a third rotating shaft 602 rotatably connected to the mounting plates 601. The two mounting plates 601 are respectively engaged with the two end covers 203. The third rotating shaft 602 is rotatably connected to a connecting rod 603. The connecting rod 603 is rotatably connected to a mounting shaft 604. The upper cover 7 is rotatably connected to a fixed shaft 606. The fixed shaft 606 is fixedly connected to a driving disk 605. The mounting shaft 604 is rotatably connected to the driving disk 605. The fixed shaft 606 is slidably connected to a The connecting rod 607 has a fixing plate 610 fixedly connected to the bottom of the connecting rod 607, and two fixing blocks 611 are fixedly connected to the fixing plate 610. The upper cover 7 is provided with two fixing grooves 612, and the two fixing blocks 611 are respectively engaged with the two fixing grooves 612. The connecting rod 607 has a second pressing block 608 fixedly connected, and a second spring 609 is fixedly connected between the second pressing block 608 and the fixed shaft 606. First, when the upper cover 7 needs to be removed from the end cover 203 for internal inspection, the second pressing block 608 is pressed by a hexagonal wrench. When the second pressing block 608 moves downward, the second spring 609 contracts. At the same time, the second pressing block 608 drives the connecting rod 607 to move downward, so that the connecting rod 607 drives the fixing plate 610 to move downward, and the fixing plate 610 drives the fixing block 611 to no longer engage with the fixing groove 612. At this time, the fixing shaft 606 is rotated by the hexagonal wrench, and the fixing shaft 606 drives the driving disk 605 to rotate. The driving disk 605 makes the installation shaft 604 drive the connecting rod 603 to move, and the connecting rod 603 drives the installation plate 601 to slide through the third rotating shaft 602. When the driving disk 605 rotates 180 degrees, the installation After the mounting plate 601 slides until it is no longer engaged with the end cover 203, the upper cover 7 can be disassembled and assembled. The upper cover 7 can be quickly disassembled and assembled by engaging the mounting plate 601 with the end cover 203, shortening the time required to open and close the upper cover 7 during maintenance, allowing maintenance personnel to perform internal maintenance more quickly, thereby improving the overall maintenance efficiency. At the same time, the upper cover 7 is installed by engaging the mounting plate 601 with the end cover 203, without the problem of thread wear, and a reliable connection can be maintained at all times, ensuring that the upper cover 7 stably covers the end cover 203, providing good protection for internal components.

[0040] When the present invention is in use, first, when it is necessary to remove the upper cover 7 from the end cover 203 to inspect the interior, the second pressing block 608 is pressed by the hexagonal wrench. When the second pressing block 608 moves downward, the second spring 609 contracts, and at the same time, the second pressing block 608 drives the connecting rod 607 to move downward, so that the connecting rod 607 drives the fixing plate 610 to move downward, and the fixing plate 610 drives the fixing block 611 to no longer engage with the fixing groove 612. At this time, the fixing shaft 606 is rotated by the hexagonal wrench, and the fixing shaft 606 drives the driving disk 605 to rotate. The driving disk 605 causes the installation shaft 604 to drive the connecting rod 603 to move, and the connecting rod 603 drives the third rotating shaft 602 to drive the connecting rod 603 to move. The movable mounting plate 601 slides. When the driving disk 605 rotates 180 degrees, the mounting plate 601 slides until it is no longer engaged with the end cover 203, and the upper cover 7 can be disassembled and assembled. The mounting plate 601 is engaged with the end cover 203 to quickly realize the disassembly and installation of the upper cover 7, which shortens the time required for opening and closing the upper cover 7 during the inspection and maintenance process, so that the maintenance personnel can inspect the internal parts more quickly, thereby improving the overall inspection and maintenance efficiency. At the same time, the upper cover 7 is installed by the way that the mounting plate 601 is engaged with the end cover 203, and there is no problem of thread wear. A reliable connection can be maintained at all times, ensuring that the upper cover 7 stably covers the end cover 203, providing good protection for the internal components.

[0041] After lubricating the guide rail 201 and the first screw rod 204, excess lubricating oil will drip into the collection frame 301, and the lubricating oil will be collected by the collection frame 301 to prevent the lubricating oil from dripping to the bottom of the base 1, making the base 1 greasy and increasing the difficulty of inspecting and maintaining the base and related components. At the same time, by starting the motor 205, the output shaft of the motor 205 rotates and drives the first screw rod 204 to rotate. When the first screw rod 204 rotates, the thread drives the slide 206 to slide. When the slide 206 slides, the rack 208 drives the gear 303 to rotate, so that the gear 303 drives the first rotating shaft 302 to rotate, and the first rotating shaft 302 drives the stirring rod 304 to rotate. When the stirring rod 304 rotates, the lubricating oil collected in the collection frame 301 can be properly stirred. Proper stirring makes the contact between the lubricating oil and the air more uniform, avoids excessive oxidation of local areas due to long-term contact with the air, and also enables additives such as antioxidants to play a better role, slowing down the whole The oxidation speed of the body is reduced, the good quality of the lubricating oil is maintained, and it is beneficial to the subsequent storage and reuse. When the collecting frame 301 needs to be pulled out from the base 1, firstly, the second screw rod 210 is inserted with an inner hexagonal wrench, and the second screw rod 210 is rotated. The second screw rod 210 thread drives the slide plate 209 to slide upward, and the slide plate 209 slides upward to drive the slide bar 207 to move upward, and the slide bar 207 drives the rack 208 to move upward. When the rack 208 moves upward to a certain distance, it will not The sliding out of the collection frame 301 is hindered. At this time, the iron block 306 is rotated so that it is no longer adsorbed with the magnetic block 307. When the iron block 306 is adsorbed with the magnetic block 307, the stability of the iron block 306 can be improved. At the same time, the iron block 306 can resist and limit the collection frame 301 to prevent the collection frame 301 from sliding out and enhance stability. After the iron block 306 is rotated onto the carrying block 308, the collection frame 301 can be slid out of the base 1, so as to carry out subsequent treatment of the collected lubricating oil;

[0042] At the same time, when the fit between the slider 403 and the guide rail 201 is too tight, use the hexagonal wrench to pass through the through hole 506, and then press the first pressing block 504 to make it move downward. In this process, the first spring 505 is compressed by the pressure, and the first pressing block 504 drives the connecting block 501 and the limiting rod 502 to move downward synchronously until the limiting rod 502 is no longer engaged with the limiting hole 503. At this time, the second rotating shaft 407 is rotated. The rotation of the second rotating shaft 407 will drive the driving shaft 404 to roll in the driving groove 406. Since the driving groove 406 is elliptical, the driving shaft 404 can simultaneously drive the two mounting rods 402 to slide toward or away from each other. When the mounting rod 402 slides, the guide rod 408 slides with the mounting rod 402 to ensure the stability of the sliding of the mounting rod 402 and avoid the problems such as jamming and deviation that may be caused by unstable sliding. At the same time, the mounting rod 402 drives the two sliders 403 to move. In this way, the slider 403 realizes sliding adjustment. This adjustment method can avoid the slider 403 and the guide rail 201 from being too tight due to thermal expansion, prevent the sliding from being not smooth, avoid the guide rail 201 from being too tight and sliding not smooth, increase the friction between the two, thereby aggravating the degree of wear and seriously affecting their service life. Through timely adjustment, the slider 403 and the guide rail 201 can maintain a suitable gap to ensure stable operation of the equipment. After the sliding adjustment of the slider 403 is completed, it is only necessary to pull out the hexagonal wrench. At this time, the first spring 505 will restore its deformation and push the limit rod 502 to move upward so that it can re-engage with the limit hole 503. Through the engagement of the limit rod 502 with the limit hole 503, the rotation of the second rotating shaft 407 and the connecting disk 405 after rotation can be effectively limited, so as to prevent the position of the slider 403 from changing due to accidental rotation, and ensure that the equipment always maintains a good working condition during subsequent operation.
