Description
Technical Field
[0001] This application relates to the technical field of guide rail production and manufacturing, and particularly relates to a heavy-duty rolling guide rail pair capable of equalizing errors. Background Art
[0002] A rolling guide rail pair is a rolling moving part. The infinite rolling cycle of rolling elements (steel balls or rollers) between the slider and the guide rail enables the load platform to perform high-precision linear motion along the guide rail; the rolling linear guide rail pair has good bearing performance and can withstand force and torque loads in different directions.
[0003] During the use of the existing rolling linear guide rail pair, especially under heavy load conditions, the center of gravity may shift due to the different positions of the loaded object above the guide rail pair, which may cause stress concentration during the movement of the guide rail pair, accelerating wear and reducing the service life. Utility Model Content

[0005] To achieve the above object, this application provides the following technical solution: A heavy-duty rolling guide rail pair capable of equalizing errors, including a slider. Both sides inside the slider are provided with rolling grooves. Fixing plates are arranged inside the rolling grooves. Rolling elements are arranged on both the upper and lower sides of the fixing plates. The rolling elements are slidably connected inside the rolling grooves. A stabilizing mechanism is arranged inside the slider. The stabilizing mechanism includes a sliding member. Two placement grooves are formed at the top of the sliding member. Support plates are arranged inside the two placement grooves. A connecting member is arranged between the two support plates. Multiple connecting grooves are formed at the top of the sliding member. Multiple connecting members are located inside the connecting grooves. Multiple moving shafts are arranged between the multiple connecting members and the sliding member. The connecting member is rotatably connected to the sliding member through the connecting member.
[0006] By adopting the above technical solution and setting a slider, multiple sets of rolling elements can improve the stability of sliding when the slider slides outside the guide rail. The load is located at the top of the slider, and the top of the set support plate abuts against the bottom of the slider. Under the action of the connecting parts and the moving shaft, a dynamic balancing force is provided for the contact surface between the bottom of the slider and the guide rail. Under heavy load, the load-bearing capacity can be effectively improved, and the stress concentration on one side of the slider can be reduced when bearing load, so as to realize the concentration of load-bearing force and stress balance, further reduce wear, and effectively improve stability and service life.
[0007] As a preferred technical solution of this application, the inner sides of both sets of sliders are provided with oil outlet grooves, the oil outlet grooves are located above the rolling grooves, and the outer sides of the sliders are provided with two sets of oil inlets, the two sets of oil inlets being interconnected with each other.
[0008] By adopting the above technical solution, the oil outlet groove can be filled with oil from the oil inlet and seep out from the inside of the oil outlet groove. The seeping lubricating oil will achieve a comprehensive lubrication effect between the guide rail and the slider under the action of gravity and the sliding of the slider on the guide rail, which can further reduce wear and improve service life.
[0009] As a preferred technical solution of this application, the slider is provided with a protective mechanism on both the front and back sides. The protective mechanism includes a guard plate, and the front side of the guard plate is provided with an inclined plate. The position of the inclined plate is the same as the internal shape of the slider.
[0010] By adopting the above technical solution, the protective mechanism can clean and scrape off the dust outside the guide rail during the movement of the slider, ensuring that it will not enter between the guide rail and the slider and affect normal movement, thus maintaining stability during use.
[0011] As a preferred technical solution of this application, the inner side of the slider is provided with two sets of inclined grooves, and the interior of each set of inclined grooves is provided with multiple sets of support rollers.
[0012] By adopting the above technical solution, the inclined groove can further improve the stability during movement, further enhance the support effect, and make it more stable during use.
[0013] As a preferred technical solution of this application, a stabilizing pad is provided on one side of the guard plate, and the stabilizing pad is located between the guard plate and the slider.
[0014] By adopting the above technical solution and setting the stabilizing pad, a more stable connection can be achieved between the protective mechanism and the slider during use, further improving the sealing performance and the tightness of the connection.
[0015] As a preferred technical solution of this application, a threaded groove is provided on one side of the guard plate, and a connecting bolt is provided inside the threaded groove. Multiple sets of the connecting bolts all pass through the guard plate and the threaded connection between the stabilizing pad and the slider.
[0016] By adopting the above technical solution, the threaded groove can quickly achieve a faster connection between the protective mechanism and the slider, and subsequent disassembly and maintenance are more convenient, thus improving the practicality of the device.
[0017] The beneficial effects of this application are:
[0018] 1. By setting up a slider, multiple sets of rolling elements can improve the stability of sliding when the slider slides outside the guide rail. The load is located at the top of the slider, and the top of the set support plate abuts against the bottom of the slider. Under the action of the connecting parts and the moving shaft, a dynamic balancing force is provided for the contact surface between the bottom of the slider and the guide rail. Under heavy load, the load-bearing capacity can be effectively improved, and the stress concentration on one side of the slider can be reduced when bearing load, so as to realize the concentration of load-bearing force and stress balance, further reducing wear and effectively improving stability and service life.
[0019] 2. The oil outlet groove is designed so that oil can enter the interior of the oil outlet groove from the oil inlet and seep out from the interior of the oil outlet groove. The seeping lubricating oil will achieve a comprehensive lubrication effect between the guide rail and the slider under the action of gravity and the sliding of the slider on the guide rail, which can further reduce wear and extend service life.

The connecting members 204 are rotatably connected to the slider 201 through the connecting members 204. The slider 1 is provided with a protective mechanism 3 on both the front and back sides. The protective mechanism 3 includes a guard plate 301. The front of the guard plate 301 is provided with an inclined plate 302. The position of the inclined plate 302 is the same as the internal shape of the slider 1.
[0028] By setting up slider 1, multiple sets of rolling elements 401 can improve the stability of sliding when slider 1 slides outside the guide rail. The load is located at the top of slider 1, and the top of the support plate 205 abuts against the bottom of slider 1. Under the action of connector 204 and moving shaft 203, a dynamic balancing force is provided for the contact surface between the bottom of slider 1 and the guide rail. Under heavy load, it can effectively improve the load-bearing capacity and reduce the concentration of stress on one side of slider 1, achieving load concentration and stress balance, further reducing wear, and effectively improving stability and service life. The protective mechanism 3 can clean and scrape off dust from the outside of the guide rail during the movement of slider 1, ensuring that it does not enter between the guide rail and slider 1 and affect normal movement, maintaining stability during use.
[0029] Reference Figure 1 Both sets of sliders 1 have oil outlet grooves 102 on their inner sides, located above the rolling grooves 101. Two sets of oil inlets 105 are provided on the outside of sliders 1, and both sets of oil inlets 105 are interconnected. Two sets of inclined grooves 103 are provided on the inner side of sliders 1, and multiple sets of support rollers 104 are provided inside each of the inclined grooves 103. A threaded groove 303 is provided on one side of the guard plate 301, and connecting bolts 304 are provided inside the threaded groove 303. Multiple sets of connecting bolts 304 threadedly connect the guard plate 301 and the stabilizing pad 305 to the sliders 1. The oil outlet grooves are provided... 102 can enter the interior of the oil outlet 102 through the oil inlet 105 and seep out from the interior of the oil outlet 102. The seeping lubricating oil will achieve a comprehensive lubrication effect between the guide rail and the slider 1 under the action of gravity and the sliding of the slider 1 on the guide rail, which can further reduce wear and extend service life. The inclined groove 103 can further improve the stability during movement and further improve the support effect, making it more stable during use. The threaded groove 303 can quickly achieve a faster connection between the protective mechanism 3 and the slider 1, and subsequent disassembly and maintenance are more convenient, improving the practicality of the device.
[0030] Reference Figure 1 A stabilizing pad 305 is provided on one side of the guard plate 301, and the stabilizing pad 305 is located between the guard plate 301 and the slider 1. When in use, the stabilizing pad 305 can achieve a more stable connection between the protective mechanism 3 and the slider 1, and further improve the sealing and tightness of the connection.
[0031] Working principle: By setting up slider 1, when slider 1 slides outside the guide rail, multiple sets of rolling elements 401 can improve the stability of sliding. The load is located at the top of slider 1, and the top of the set support plate 205 abuts against the bottom of the slider 1. Under the action of connecting part 204 and moving shaft 203, dynamic balance force is provided for the contact surface between the bottom of slider 1 and the guide rail. Under heavy load, the load-bearing effect can be effectively improved. When bearing load, the stress concentration to one side of slider 1 is reduced, realizing the concentration of load-bearing force and stress balance, further reducing wear, effectively improving stability and service life. The set oil outlet groove 102 can enter the interior of oil outlet groove 102 from oil inlet 105 and seep out from the interior of oil outlet groove 102. The seeping lubricating oil will achieve a comprehensive lubrication effect between the guide rail and slider 1 under the action of gravity and the sliding of slider 1 on the guide rail, which can further reduce wear and improve service life.
[0032] The protective mechanism 3 can clean and scrape off the dust outside the guide rail during the movement of the slider 1, ensuring that it will not enter between the guide rail and the slider 1 and affect the normal movement, thus maintaining stability during use. The inclined groove 103 can further improve the stability during movement and further improve the support effect, making it more stable during use.
[0033] Meanwhile, the stabilizing pad 305, when in use, can achieve a more stable connection between the protective mechanism 3 and the slider 1, further improving the sealing performance and the tightness of the connection;
[0034] In addition, the threaded groove 303 allows for a faster connection between the protective mechanism 3 and the slider 1, and makes subsequent disassembly and maintenance more convenient, thus improving the practicality of the device.
