Description

Technical Field

[0001] This utility model relates to the field of rigid rail accessories technology, and in particular to a high-efficiency heat dissipation and protection structure for rigid rails. Background Technology

[0002] A rigid rail, also known as a hardened guide rail, is a key component in machining equipment (such as CNC machine tools and machining centers) used to support and guide moving parts (such as worktables and slides) to perform linear or rotary movements in a specific direction.

[0003] The existing rigid rails and their moving structures are directly exposed to the outside. The reciprocating motion of the moving structures generates heat, so lubricating oil is applied to the rigid rails to reduce friction. However, the lubricating oil has a certain viscosity, and after it adheres to fine particulate impurities, these impurities directly enter the space between the moving structures and the rigid rails, increasing wear.

[0004] Therefore, it is necessary to provide a new high-efficiency heat dissipation and protection structure for rigid rails to solve the above-mentioned technical problems. Utility Model Content

The connecting shaft is provided with a threaded section, and a limiting block that contacts the extension plate and is used to stabilize the angle of the cooling fan is sleeved on the external thread of the threaded section.

[0011] Preferably, the limiting block is provided with an anti-slip pad on the side near the extension plate to increase friction, and two dustproof nets are installed inside the housing, with the two dustproof nets located on both sides of the fan blade.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1-4 ,in, Figure 1 A top view schematic diagram of a preferred embodiment of the high-efficiency heat dissipation and protection structure for rigid rails provided by this utility model; Figure 2 This is a schematic diagram of the main structure of the protective plate in this utility model; Figure 3 This is a bottom view of the cooling fan structure in this utility model; Figure 4 This is a schematic diagram of the assembly structure of the connecting shaft and the limiting block in this utility model.

[0024] The high-efficiency heat dissipation and protection structure for rigid rails includes: a protective plate 1 mounted on the moving part of the rigid rail for protecting the rigid rail; a scraper 7 hinged to the protective plate 1 for scraping away impurities; a slider 5 slidably mounted on the protective plate 1; a connecting rod 6 hinged to the slider 5 and hinged to the scraper 7; the scraper 7 has a locking slot that can be locked onto the outside of the rigid rail, and a silicone pad 8 in contact with the rigid rail is provided in the locking slot; the scraper 7 and the connecting rod 6 are arranged in groups and are respectively located on both sides of the slider 5; an adjustment mechanism is provided on the protective plate 1 for adjusting the angle of the scraper 7. By setting the protective plate 1, the rigid rail is protected, avoiding accidental damage to the rigid rail caused by external factors. The scraper 7 and the silicone pad 8 inside its bayonet effectively remove impurities from the surface of the hard rail. The silicone pad 8, in contact with the hard rail, effectively removes fine particles of lubricating oil, reducing the amount of impurities entering between the moving structure and the hard rail, thus reducing wear. The slider 5, connecting rod 6, and the grouped scrapers 7 and connecting rod 6 make the movement of the scraper 7 more stable and flexible. The adjustment mechanism allows the angle of the scraper 7 to be adjusted according to actual needs, ensuring that the scraper 7 always maintains good contact with the hard rail, further improving the effect of removing impurities and ensuring the efficient heat dissipation and protection performance of the hard rail. The grouped scrapers 7 can remove impurities in different directions in advance when the moving parts move in different directions.

[0025] The adjustment mechanism includes an electric telescopic rod 11 fixed to the top of the protective plate 1, and a connecting plate 10 installed on the output rod of the electric telescopic rod 11 and connected to the slider 5. By setting the electric telescopic rod 11 (taking the SXTL small electric push rod telescopic rod as an example), the angle and position of the scraper 7 are automatically adjusted without manual operation, thus improving the adjustment efficiency. By setting the connecting plate 10, the output rod of the electric telescopic rod 11 and the slider 5 are connected, so that the power of the electric telescopic rod 11 can be stably transmitted to the slider 5, thereby driving the scraper 7 to adjust its angle. This design allows the scraper 7 to flexibly adjust its contact angle and force with the hard rail according to the actual situation of the hard rail surface and the working requirements, ensuring the best effect of scraping impurities.

[0026] The bottom of the protective plate 1 is fixed with a mounting bracket 12, which is connected to the rigid rail moving part by fixing bolts 13. A cooling fan 4 for assisting in cooling the rigid rail is installed at the bottom of the protective plate 1. By setting the mounting bracket 12 and fixing bolts 13, the protective plate 1 is stably installed on the rigid rail moving part, ensuring that the protective plate 1 can move synchronously with the rigid rail moving part, thereby continuously providing protection for the rigid rail and preventing impurities from entering and external factors from interfering. The cooling fan 4 plays a role in assisting in cooling the rigid rail. The cooling fan 4 can accelerate the airflow around the rigid rail, remove the heat generated by the reciprocating motion of the rigid rail due to the moving structure, effectively reduce the working temperature of the rigid rail, and improve the service life and working efficiency of the rigid rail.

[0027] The cooling fan 4 is supported by a motor housing 15 mounted on the protective plate 1, a housing 14 fixed to the motor housing 15, a support frame 16 mounted inside the housing 14, a rotating shaft 17 rotatably mounted on the support frame 16, and fan blades 18 fixed to the rotating shaft 17. The motor housing 15 houses a servo motor whose output shaft is connected to the rotating shaft 17 via a coupling. By setting up the motor housing 15, the servo motor (taking PMM2802 as an example) is protected, preventing interference and damage from the external environment and ensuring its stable operation. The housing 14 protects the fan blades 18 and internal structure, preventing them from being impacted or damaged during operation. By setting up the support frame 16, the rotating shaft 17, and the fan blades 18, the fan blades 18 can rotate stably under the drive of the servo motor, generating strong airflow to effectively assist the hard rail in heat dissipation. By setting up the servo motor and connecting it to the rotating shaft 17 through a coupling, precise control of the fan blade speed 18 is achieved. The airflow of the cooling fan 4 can be adjusted according to the actual working temperature of the hard rail, making the heat dissipation effect more efficient and further improving the working performance and stability of the hard rail.

[0028] An extension plate 2 is fixed to the bottom of the protective plate 1. A connecting shaft 20, which is rotatably mounted on the extension plate 2 and connected to the cooling fan 4, is provided on the connecting shaft 20. A limiting block 3, which contacts the extension plate 2, is provided on the external thread of the connecting shaft 20 to stabilize the angle of the cooling fan 4. By setting the extension plate 2, the cooling fan 4 is provided with additional support and installation space, which facilitates the arrangement and fixation of the cooling fan 4. By setting the connecting shaft 20, the rotatable connection between the cooling fan 4 and the extension plate 2 is realized, so that the cooling fan 4 can adjust its angle according to actual needs to better align with the hard rail for heat dissipation. By setting the threaded section on the connecting shaft 20 and threading the limiting block 3, the angle of the cooling fan 4 is stabilized. When the cooling fan 4 is adjusted to a suitable angle, the limiting block 3 can be tightened to make it in close contact with the extension plate 2, thereby fixing the position of the cooling fan 4 and preventing it from shifting during operation, ensuring that the cooling fan 4 can continuously and stably dissipate heat from the hard rail.

[0029] The limiting block 3 has an anti-slip pad on the side near the extension plate 2 to increase friction. Two dustproof nets 19 are installed inside the housing 14, located on both sides of the fan blade 18. By setting the anti-slip pad, the friction between the limiting block 3 and the extension plate 2 is increased, allowing the limiting block 3 to more firmly fix the angle of the cooling fan 4 and prevent it from loosening due to vibration or external force. This ensures that the cooling fan 4 always maintains the optimal heat dissipation position. By installing two dustproof nets 19 inside the housing 14, located on both sides of the fan blade 18, dust and impurities are prevented from entering the cooling fan 4, protecting the fan blade 18 and motor from contamination and damage, extending the service life of the cooling fan 4, and ensuring that the cooling efficiency of the cooling fan 4 is not affected.

[0030] The protective plate 1 is provided with a groove 9, and a guide block is slidably installed in the groove 9. The guide block is connected to the slider 5. The groove 9, together with the guide block, is used to limit the movement path of the slider 5. By setting the groove 9, a stable movement path for the slider 5 is achieved. The groove 9, as a guide structure for the movement of the slider 5, ensures that the slider 5 can slide along a predetermined trajectory. By slidably installing the guide block in the groove 9 and connecting the guide block to the slider 5, it plays the role of connecting and guiding the movement of the slider 5, making the sliding of the slider 5 in the groove 9 more stable and smooth. Through the cooperation of the groove 9 and the guide block, the movement path of the slider 5 is effectively limited, preventing the slider 5 from deviating or shaking during movement, thereby ensuring the stability of the scraper 7 and other components connected to the slider 5.

[0031] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0032] The working principle of the high-efficiency heat dissipation and protection structure for rigid rails provided by this utility model is as follows:

[0033] This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here.

[0034] In use, first securely install the protective plate 1 onto the rigid rail moving part using the mounting bracket 12 and fixing bolts 13. Adjust the angle of the cooling fan 4 to a suitable position and tighten the limit block 3 for fixation. Start the electric telescopic rod 11, servo motor and other electrical equipment through the electrical control cabinet. Adjust the angle of the scraper 7 of the electric telescopic rod 11 to make good contact with the rigid rail. The servo motor drives the cooling fan 4 to rotate and start cooling the rigid rail. When the rigid rail moving part moves, the scraper 7 scrapes away impurities on the surface of the rigid rail. The cooling fan 4 continuously cools the rigid rail and reduces its working temperature. When the moving part moves in another direction, adjust the extension length of the output rod of the electric telescopic rod 11 to replace the scraper 7 in contact with the rigid rail, so that the front of the moving part's movement path is always kept clean (adjusting the degree of contact between the scraper 7 and the rigid rail can prevent the lubricating oil from being scraped off as well).

By setting an adjustment mechanism, the angle and position of the scraper 7 can be automatically adjusted without manual operation, improving adjustment efficiency and ensuring that the scraper 7 always maintains good contact with the rigid rails, thus improving the effect of scraping impurities.
