Description

Technical Field

[0001] The utility model relates to the technical field of linear modules, in particular to a dustproof self-lubricating linear module device. Background Art

[0002] Linear guides are used to support and guide moving parts to make reciprocating linear motion in a given direction. At present, the linear guides on the market are composed of guide rails, slider bodies and balls. The linear motion is achieved by the rolling of balls in the grooves. The rolling of balls in the grooves will damage the slider grooves over time, resulting in reduced movement accuracy, poor durability, slow movement speed, and high noise. In addition, the use of balls often requires the linear guide to be equipped with oil nozzles to supply oil to the balls for lubrication. There is also a linear guide composed of an optical axis, a slider and a roller.

[0003] However, this type of linear guide has disadvantages such as poor load-bearing capacity and poor transmission accuracy.

[0004] For example, the self-lubricating high-speed silent linear guide disclosed in Chinese patent CN206159278U has a simple structure and is easy to install and use. It can be installed in harsh environments to achieve smooth, low-noise, high-speed, and precise movement, with high transmission accuracy and the ability to carry heavy objects. There is no need to set up an oil supply and lubrication device for the slider, and the structure is more streamlined.

[0005] However, although the dust-proof sheet at the outer end of the linear guide rail can scrape the dust on the outer end of the guide rail to the left and right ends of the guide rail to protect the main part of the guide rail from dust, the dust scraped to the left and right ends will adhere to the left and right ends of the guide rail to form dirt, which will be difficult to clean after long-term accumulation.

[0006] For this reason, we urgently need to provide a dust-proof self-lubricating linear module device that can clean dust. Utility Model Content

[0007] The purpose of the utility model is to provide a dustproof self-lubricating linear module device to solve the problem that the dustproof sheet at the outer end of the linear guide proposed in the above-mentioned background technology can scrape the dust at the outer end of the guide to the left and right ends of the guide to protect the main part of the guide from dust, but the dust scraped to the left and right ends will adhere to the left and right ends of the guide to form dirt, which will be difficult to clean after long-term accumulation.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dustproof self-lubricating linear module device, comprising a guide rail and a right support column, the right support column is installed at the right end of the guide rail, the left end of the guide rail is installed with a left support column, the outer end of the guide rail is slidably connected to the original slider body, and the outer end of the guide rail is connected to a dustproof mechanism.

[0009] The dust-proof mechanism includes sliding plates fixedly connected to the left and right ends of the slider body. A push plate is fixedly connected to the side of the sliding plate away from the slider body. Electric push rods are installed on the upper sides inside the right support column and the left support column. The lower end of the output shaft of the electric push rod is fixedly connected to a scraping plate. The inside of the left support column and the slider body is hollow. A material collection box is slidably connected to the bottom end inside the left support column and the slider body. A sealing plate is connected below the front end of the material collection box. A handle is fixedly connected to the lower end of the front side of the sealing plate.

[0010] Further improvement lies in that discharge holes are provided above the left end inside the right support column and above the right end inside the left support column. The lower sides of the left and right ends of the guide rail are fixedly connected to the inner bottom ends of the discharge holes. The outer sides between the left and right ends of the guide rail and the inner sides of the discharge holes are slidably connected to the outer side of the push plate. The inner side of the push plate is slidably connected to the outer side of the guide rail. Thus, when the slider body moves to the leftmost or rightmost end of the guide rail, the push plate at its outer end can push the dust attached to the outer side of the guide rail to the inside of the right support column or the left support column at both ends of the left and right guide rails.

[0011] Further improvement lies in that the left and right sides of the guide rail are slidably connected to the outer edge of the scraping plate. Thus, when the end of the push plate away from the slider body is flush with the left or right side of the guide rail, by starting the electric push rod, its output shaft extends to drive the scraping plate to move down. When passing through the side of the push plate away from the slider body, the dust and lubricating oil mixed dirt attached to the side of the plate away from the slider body can be scraped off and then fall into the lower material collection box to be collected.

[0012] Further improvement lies in that discharge ports are provided below the front ends of the right support column and the left support column. The upper end of the sealing plate is hinged to the upper end of the inner side of the discharge port. The outer side of the sealing plate is slidably connected to the inner side of the discharge port. The rear end of the sealing plate abuts against the front side of the material collection box. Thus, after the linear module finishes working, by pulling the handle forward, the sealing plate rotates forward and upward, and then the material collection box is pulled out from the discharge port to remove the dust and lubricating oil mixed dirt therein.

[0013] Further improvement lies in that a lubricating mechanism is provided at the left end of the right support column. The lubricating mechanism includes an oil storage box fixedly connected above the left side of the right support column. A refueling pipe is fixedly connected to the upper end of the oil storage box. A U-shaped plate is fixedly connected to the lower side of the oil storage box. A spring is fixedly connected to the right end inside the U-shaped plate. A moving block is fixedly connected to the left end of the spring. Limit blocks are fixedly connected to the front and rear sides of the moving block. An oil inlet pipe is provided at the upper end of the slider body.

[0014] A further improvement is that an oil outlet hole is formed in the left side of the inner bottom end of the oil storage box, horizontal sliding grooves are formed at the front and rear ends of the inner side of the U-shaped plate, the front and rear ends of the moving block are slidably connected to the inner side of the U-shaped plate, the outer side of the limiting block is slidably connected to the inner side of the sliding groove, and the upper side of the moving block is slidably connected to the position of the oil outlet hole on the lower side of the oil storage box. Thus, when the spring is not affected by external forces, it will push the moving block to move to the position of the oil outlet hole on the lower side of the oil storage box to close the oil outlet hole.

[0015] A further improvement is that the upper right side of the upper end of the oil inlet pipe abuts against the left side of the moving block, and the upper side of the oil inlet pipe is slidably connected to the lower side of the oil storage box. Thus, when the slider body moves to the right end of the guide rail, the upper end of the oil inlet pipe first contacts the left side of the moving block and then pushes the moving block to the right.

[0016] In summary, the present application discloses a dust-proof self-lubricating linear module device.

[0017] In this technical solution, when the slider body moves to the leftmost or rightmost end of the guide rail, the push plate at its outer end can push the dust attached to the outer side of the guide rail to the inside of the right support column or left support column at both ends of the left and right guide rails. And when the end of the push plate away from the slider body is flush with the left or right side of the guide rail, by starting the electric push rod, its output shaft extends to drive the scraper to move down. When passing through the side of the push plate away from the slider body, the dust and lubricating oil mixed dirt attached to the side of the push plate away from the slider body are scraped off and then fall into the lower material collection box to be collected. Thus, the dust cleaned on the guide rail can be timely processed and will not accumulate at both ends of the guide rail.

[0018] Furthermore, when the slider body moves to the right end of the guide rail, the upper end of the oil inlet pipe first contacts the left side of the moving block and then pushes the moving block to the right until the oil inlet pipe moves to the lower side of the oil outlet hole. At this time, the moving block no longer blocks the oil outlet hole, and the oil in the oil storage box enters the oil inlet pipe through the oil outlet hole, and then enters the inside of the slider body from the lower end of the oil inlet pipe to lubricate the slider body, making the slider body move more smoothly. Then when the slider body moves left again, the moving block is pushed back by the spring to move back to the lower end of the oil outlet hole to block the oil outlet hole again.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-6 , the present utility model provides a technical solution: a dust-proof self-lubricating linear module device, including a guide rail 1 and a right support column 2. The right support column 2 is installed at the right end of the guide rail 1, and a left support column 3 is installed at the left end of the guide rail 1. The outer end of the guide rail 1 is slidably connected to the original slider body 4, and the outer end of the guide rail 1 is connected with a dust-proof mechanism.

[0028] The dust-proof mechanism includes sliding plates 501 fixedly connected to the left and right ends of the slider body 4. A push plate 502 is fixedly connected to the side of the sliding plate 501 away from the slider body 4. Drainage holes are opened above the left end inside the right support column 2 and above the right end inside the left support column 3. The lower sides of the left and right ends of the guide rail 1 are fixedly connected to the inner bottom ends of the drainage holes. The outer sides of the left and right ends of the guide rail 1 and the inner sides of the drainage holes are slidably connected to the outer side of the push plate 502. The inner side of the push plate 502 is slidably connected to the outer side of the guide rail 1. Thus, when the slider body 4 moves to the leftmost or rightmost end of the guide rail 1, the push plate 502 at its outer end can push the dust attached to the outer side of the guide rail 1 to the inside of the right support column 2 or the left support column 3 at both ends of the left and right guide rails 1.

[0029] An electric push rod 503 is installed on the upper side inside the right support column 2 and the left support column 3. The lower end of the output shaft of the electric push rod 503 is fixedly connected with a scraper 504. The interiors of the left support column 3 and the slider body 4 are hollow. A material collection box 505 is slidably connected to the bottom ends inside the left support column 3 and the slider body 4. The left and right sides of the guide rail 1 are slidably connected to the outer edge of the scraper 504. Thus, when the push plate 502 pushes the dust at the outer end of the guide rail 1 to the left and right ends of the guide rail 1, and the end of the push plate 502 away from the slider body 4 is flush with the left or right side of the guide rail 1, by starting the electric push rod 503, its output shaft extends to drive the scraper 504 to move down. When passing by the side of the push plate 502 away from the slider body 4, the mixed dirt of dust and lubricating oil attached to the side of the push plate 502 away from the slider body 4 is scraped off and then falls into the lower material collection box 505 to be collected.

[0030] A sealing plate 506 is connected to the lower front of the material collection box 505. A handle 507 is fixedly connected to the lower front side of the sealing plate 506. A discharge port is opened below the front ends of the right support column 2 and the left support column 3. The upper end of the sealing plate 506 is hinged to the upper inner end of the discharge port through a hinge. The outer side of the sealing plate 506 is slidably connected to the inner side of the discharge port. The rear end of the sealing plate 506 abuts against the front side of the material collection box 505. Thus, after the linear module finishes working, by pulling the handle 507 forward, the sealing plate 506 rotates forward and upward, and then the material collection box 505 is pulled out from the discharge port to remove the mixed dirt of dust and lubricating oil therein.

[0031] A lubrication mechanism is arranged at the left end of the right support column 2. The lubrication mechanism includes an oil storage box 601 fixedly connected to the upper left side of the right support column 2. An oil filling pipe 602 is fixedly connected to the upper end of the oil storage box 601. A U-shaped plate 603 is fixedly connected to the lower side of the oil storage box 601. A spring 604 is fixedly connected to the right end inside the U-shaped plate 603. A moving block 605 is fixedly connected to the left end of the spring 604. A lower oil hole is opened at the left side of the bottom end inside the oil storage box 601. Horizontal sliding grooves are opened at the front and rear ends inside the U-shaped plate 603. The front and rear ends of the moving block 605 are slidably connected to the inner side of the U-shaped plate 603. The outer side of the limiting block 606 is slidably connected to the inner side of the sliding groove. The upper side of the moving block 605 is slidably connected to the position of the lower oil hole at the lower side of the oil storage box 601. Thus, when the spring 604 is not affected by external forces, it will push the moving block 605 to move to the position of the lower oil hole at the lower side of the oil storage box 601 to close the lower oil hole.

[0032] On the front and back sides of the moving block 605, there are limiting blocks 606 fixedly connected. At the upper end of the slider body 4, there is an oil inlet pipe 607. The upper right side of the oil inlet pipe 607 abuts against the left side of the moving block 605, and the upper side of the oil inlet pipe 607 is slidably connected to the lower side of the oil storage box 601. Thus, when the slider body 4 moves to the right end of the guide rail 1, the upper end of the oil inlet pipe 607 first contacts the left side of the moving block 605, and then pushes the moving block 605 to the right. Until the oil inlet pipe 607 moves below the lower oil hole, the moving block 605 no longer blocks the lower oil hole, and the oil in the oil storage box 601 enters the oil inlet pipe 607 through the lower oil hole, and then enters the inside of the slider body 4 from the lower end of the oil inlet pipe 607 to lubricate the slider body 4, making the slider body 4 move more smoothly. Then, when the slider body 4 moves left again, the moving block 605 is pushed back by the spring 604 to move back to the lower end of the lower oil hole and block the lower oil hole again.

[0033] Working principle: During the process of the slider body 4 moving outside the guide rail 1, the push plate 502 at its outer end pushes the dust attached to the outside of the guide rail 1 to the left and right ends. When the push plate 502 moves into the right support column 2 or the left support column 3, the electric push rod 503 is started to make its output shaft extend to drive the scraper 504 to move down, scraping off the dust and lubricating oil mixture dirt attached to the side of the push plate 502 away from the slider body 4 and then falling into the lower material collection box 505 to be collected, ensuring the operation of the slider body 4 while timely removing the dust attached to the outer end of the guide rail 1.
