Description

Technical Field

[0001] This utility model relates to the technical field of dustproof equipment for linear guide rails, specifically a dustproof structure for linear guide rail pairs. Background Technology

[0002] To ensure the safe operation of linear guides and prevent dust from entering their inner surfaces, a dustproof structure is required. Utility model patent application CN202220763730.7 discloses such a structure. By incorporating a dust cover, it effectively seals the guide rail's fixing points, preventing dust from entering the mounting holes and causing dust buildup that could be carried out during guide block movement, thus avoiding dust accumulation on the guide rail surface. The structure utilizes a rotating shaft, a brush, and a fixing nut to achieve the desired dust-proof effect. The movement of the guide block cleans the dust on the guide rail, preventing dust accumulation at the interface between the guide rail and the guide block, thus avoiding the need for regular cleaning of the guide rail. According to the publicly available technical solution, existing linear guide rail dustproof equipment has two main problems. First, when using dustproof plates and other structures for sealing and dustproofing, the seal is easily compromised due to long-term wear, resulting in a loss of dustproof effect. Second, when cooling and dustproofing the linear guide rail, the filter screen is easily clogged, which is detrimental to ensuring the cooling and dustproofing effects.

[0003] Therefore, how to design a dustproof structure for linear guide pairs has become the problem we need to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dustproof structure for linear guide rail pairs to solve the problems mentioned in the background technology. This utility model is reasonably designed, convenient to use, and suitable for preventing dust from entering and affecting the movement of the guide rail.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dustproof structure for a linear guide rail pair, comprising a guide rail and a sleeve, wherein a rolling assembly is installed on the inner side of the sleeve, the rolling assembly comprising a ball bearing seat and a ball bearing, a dustproof assembly is installed on the sleeve, the dustproof assembly comprising a rubber plate and a fan duct, a ventilation assembly is installed on the inner side of the fan duct, the ventilation assembly comprising a fan and a filter screen, a connecting assembly is installed at the bottom of the sleeve, the connecting assembly comprising a base box and a port, and a pushing assembly is installed on the inner side of the base box, the pushing assembly comprising a piston and an electromagnet.

[0006] Furthermore, the sleeve is fitted onto the outside of the guide rail, the ball is installed on the inside of the ball seat, and one side of the ball seat is secured to the outside of the guide rail by the ball.

[0007] Furthermore, the other end of the ball bearing seat is engaged with the inner wall of the sleeve, and the ball bearing seats are symmetrically distributed on both sides of the guide rail.

[0008] Furthermore, the outer side of the rubber plate is bonded to the inner wall of the sleeve, the inner side of the rubber plate is sleeved on the outer side of the guide rail, and the rubber plate is installed at both ends of the sleeve.

[0009] Furthermore, the air duct is welded to the bottom of the ferrule, and the air duct is connected to the inner side of the ferrule.

[0010] Furthermore, the fan is bolted to the inside of the air duct, and the filter is bolted to the bottom of the air duct.

[0011] Furthermore, the bottom box is welded to the bottom of the ferrule, the opening is opened at the bottom of the ferrule, and one end of the bottom box is connected to the inside of the ferrule through the opening.

[0012] Furthermore, the piston is locked onto the inner wall of one end of the base box, and the electromagnet is bolted to the inner wall of the other end of the base box. The electromagnet is connected to the piston via a spring.

[0013] Beneficial effects: 1. In use, the dustproof structure of this linear guide pair connects the fan and electromagnet to the control system of the linear guide through wires. When the linear guide is working, the ball bearing seat inside the sleeve rolls on the outer side of the guide rail through the balls, reducing movement resistance and equipment wear. The fan blows air into the inner side of the sleeve through the air duct after filtering the air through the filter screen. After cooling the ball bearing seat inside the sleeve, the cooling air pressure blows a tiny gap between the inner side of the rubber plate at both ends of the sleeve and the outer side of the guide rail, allowing air to blow out through the tiny gap, thus effectively blowing away the dust attached to the guide rail. There is no direct wear between the rubber plate and the guide rail, which not only ensures the service life of the rubber plate, but also avoids dustproof failure due to wear of the rubber plate, thus ensuring the dustproof effect.

[0014] 2. In the dustproof structure of this linear guide rail, when the fan is working, the electromagnet attracts the piston to the left through magnetic force. The piston compresses the spring and moves to the left end of the bottom box. When the fan stops working, the electromagnet closes, the spring pushes the piston to the right, and the piston blows the air in the bottom box through the port to the inside of the sleeve. Although a small amount of airflow will be generated between the rubber plates at both ends of the sleeve and the guide rail, most of the air will be blown downward through the fan, thereby blowing away the dust attached to the bottom of the filter screen, preventing the filter screen from being blocked by dust, and thus ensuring the cooling and dustproof effect of the linear guide rail.

[0015] 3. The linear guide pair has a reasonable dustproof structure design, which is efficient and convenient to use, and is suitable for preventing dust from entering and affecting the movement of the guide rail. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3This utility model provides a technical solution: a dustproof structure for a linear guide rail pair, including a guide rail 1 and a sleeve 2. A rolling assembly is installed on the inner side of the sleeve 2, the rolling assembly including a ball bearing seat 4 and a ball bearing 5. A dustproof assembly is installed on the sleeve 2, the dustproof assembly including a rubber plate 3 and a fan duct 6. A ventilation assembly is installed on the inner side of the fan duct 6, the ventilation assembly including a fan 7 and a filter screen 8. A connecting assembly is installed at the bottom of the sleeve 2, the connecting assembly including a base box 9 and a through-hole 10. A pushing assembly is installed on the inner side of the base box 9, the pushing assembly including a piston 11 and an electromagnet 12. The base box 9 is welded to the bottom of the sleeve 2, the through-hole 10 is opened at the bottom of the sleeve 2, and one end of the base box 9 is connected to the inner side of the sleeve 2 through the through-hole 10. The piston 11... The electromagnet 12 is bolted to the inner wall of the other end of the base box 9. The electromagnet 12 is connected to the piston 11 via the spring 13. When the fan 7 is working, the electromagnet 12 attracts the piston 11 to the left through magnetic force. The piston 11 compresses the spring 13 and moves to the left end of the base box 9. When the fan 7 stops working, the electromagnet 12 is turned off, and the spring 13 pushes the piston 11 to the right. The piston 11 blows the air in the base box 9 through the port 10 to the inside of the sleeve 2. Although a small amount of airflow will be generated between the rubber plates 3 at both ends of the sleeve 2 and the guide rail 1, most of the air will be blown downward through the blower 6, thereby blowing away the dust attached to the bottom of the filter screen 8, preventing the filter screen 8 from being blocked by dust, and thus ensuring the cooling and dust prevention effect of the linear guide rail.

[0022] In this embodiment, the ferrule 2 is fitted onto the outer side of the guide rail 1, the ball bearing 5 is installed on the inner side of the ball bearing seat 4, one side of the ball bearing seat 4 is secured to the outer side of the guide rail 1 by the ball bearing 5, and the other end of the ball bearing seat 4 is secured to the inner wall of the ferrule 2. The ball bearing seats 4 are symmetrically distributed on both sides of the guide rail 1. The outer side of the rubber plate 3 is bonded to the inner wall of the ferrule 2, and the inner side of the rubber plate 3 is fitted onto the outer side of the guide rail 1. The rubber plate 3 is installed at both ends of the ferrule 2. The air duct 6 is welded to the bottom of the ferrule 2, and the air duct 6 is connected to the inner side of the ferrule 2. The fan 7 is installed on the inner side of the air duct 6 by bolts, and the filter screen 8 is installed on the bottom of the air duct 6 by bolts. In use, the fan 7 and the electromagnet 12 are connected by... The wires are connected to the control system of the linear guide. When the linear guide is working, the ball bearing seat 4 inside the sleeve 2 rolls on the outer side of the guide rail 1 through the ball bearing 5, reducing movement resistance and equipment wear. The fan 7 blows air into the inner side of the sleeve 2 through the filter screen 8 and the air duct 6, cooling the ball bearing seat 4 inside the sleeve 2. The air pressure then blows a tiny gap between the inner side of the rubber plate 3 at both ends of the sleeve 2 and the outer side of the guide rail 1, allowing air to blow out through the tiny gap, effectively blowing away the dust attached to the guide rail 1. There is no direct wear between the rubber plate 3 and the guide rail 1, which not only ensures the service life of the rubber plate 3, but also avoids dustproof failure due to wear of the rubber plate 3, thus ensuring the dustproof effect.

[0023] The dustproof structure of this linear guide rail provides power to all electrical equipment via an external power supply. During use, the fan 7 and electromagnet 12 are connected to the linear guide rail's control system via wires. When the linear guide rail is working, the ball bearing seat 4 inside the ferrule 2 rolls on the outer side of the guide rail 1 via the balls 5, reducing movement resistance and equipment wear. The fan 7 blows air through the filter screen 8 and into the inner side of the ferrule 2 via the air duct 6, cooling the ball bearing seat 4 inside the ferrule 2. The air pressure then creates tiny gaps between the inner side of the rubber plates 3 at both ends of the ferrule 2 and the outer side of the guide rail 1, allowing air to escape through these gaps and effectively removing dust adhering to the guide rail 1. There is no direct wear between the rubber plates 3 and the guide rail 1. This design ensures both the service life of the rubber plate 3 and prevents dustproof failure due to wear of the rubber plate 3, thus guaranteeing the dustproof effect. When the fan 7 is working, the electromagnet 12 attracts the piston 11 to the left through magnetic force. The piston 11 compresses the spring 13 and moves to the left end of the bottom box 9. When the fan 7 stops working, the electromagnet 12 is turned off, and the spring 13 pushes the piston 11 to the right. The piston 11 blows the air in the bottom box 9 through the port 10 to the inside of the sleeve 2. Although a small amount of airflow will be generated between the rubber plate 3 at both ends of the sleeve 2 and the guide rail 1, most of the air will be blown downward through the blower 6, thereby blowing away the dust attached to the bottom of the filter screen 8, preventing the filter screen 8 from being blocked by dust, and thus ensuring the cooling and dustproof effect of the linear guide rail.
