Description

Technical Field

[0001] This utility model relates to the field of roller slider technology, and in particular to an integral racetrack-type circulating roller slider assembly. Background Technology

[0002] In the field of precision mechanical transmission, the operational performance of high-end equipment such as CNC machine tools, automated production lines, and high-precision testing equipment is highly dependent on the precision stability, load-bearing reliability, and service life of linear motion components. Among them, the circulating roller slider, as the core functional component for realizing the cyclic guidance of linear motion, has a structural design that directly determines the processing accuracy, operating efficiency, and maintenance cost of the equipment. It is a key link in ensuring the "high precision, high response, and long life" operation of high-end equipment.

[0003] However, current circulating roller sliders on the market still have some shortcomings in practical applications: most products adopt a split design, which is prone to errors during assembly, resulting in a decrease in the coaxiality and parallelism of the roller circulating track, ultimately affecting the motion accuracy of the slider; at the same time, the rollers are prone to jamming and impact during the turning and circulating process, which reduces the smoothness and response speed of the motion; and the lubrication structure design of existing products is not perfect, which will aggravate the local wear of the rollers and tracks, shorten the service life of components, and fail to meet the high precision and high reliability requirements of high-end equipment. In view of this, this application proposes an integral racetrack-type circulating roller slider assembly. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an integral racetrack-type circulating roller slide block to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model employs the following technical solution: an integral racetrack-type circulating roller slide block, comprising: Both the first substrate and the second substrate are rectangular plates. The first substrate and the second substrate are symmetrically distributed front and back, and the second substrate is attached to the top of the first substrate. Two sets of sealing gaskets are provided and are respectively installed at both ends of the first substrate and the second substrate; The end caps are provided in two sets and are respectively installed on the outside of the two sealing gaskets; The circulation track is located between the first base, the second base, the two sealing gaskets, and the two end caps; The rollers are arranged in a series and installed in an orderly manner within the circulating track.

[0006] Furthermore, the circulation track consists of two straight grooves and two arc grooves. The two straight grooves are opened between the sides of the first base and the second base that are in contact with each other. One of the straight grooves extends to the front side of the first base and the second base. The two arc grooves are opened inside the sealing gaskets and end caps at both ends of the first base and the second base, respectively. The two arc grooves are respectively connected to the two ends of the two straight grooves to form an elliptical circulation track.

[0007] Furthermore, an opening is provided at the bottom of the joint between the first substrate and the second substrate, which communicates with the straight groove below the circulating track, allowing the sidewall of the roller to extend through the opening.

[0008] Furthermore, the inner walls of the straight grooves on the sides of both the first and second substrates are provided with a wear-resistant coating, which is a titanium nitride coating.

[0009] Furthermore, sealing rings made of nitrile rubber are provided on both sides of the inner wall of the circulating track to fit the rollers.

[0010] Furthermore, the first and second bases, as well as the sides of the sealing gasket and end cap, are provided with 2*3 neatly distributed positioning holes, and positioning pins are threaded into the corresponding positioning holes.

[0011] Furthermore, a one-way valve oil injection nozzle is provided at the center of the side of each of the two end caps, and the two one-way valve oil injection nozzles are respectively connected to the arc grooves at both ends of the circulation track. The end caps are made of metal copper.

[0012] The beneficial effects of this utility model are: 1. The first and second bases are symmetrically fitted together as a single unit. The first base, second base, sealing gasket, and end cap are precisely positioned by 2*3 neatly distributed positioning holes and positioning pins, further ensuring the coaxiality and parallelism of each component. This avoids the deviation of the roller running trajectory due to assembly errors and meets the motion accuracy requirements of CNC machine tools, high-precision testing equipment, etc. The circulating track is formed by the straight groove between the first and second bases, the arc groove in the sealing gasket, and the end cap to form an elliptical closed structure. It is formed by precision grinding, and the track joint is smooth. There is no seam gap like in traditional split tracks. The structure ensures the consistency of the roller circulation path and reduces the accuracy fluctuation during the movement.

[0013] 2. The straight groove and arc groove of the elliptical circulating track adopt a streamlined connection, and the curvature of the arc groove is optimized to match the roller turning trajectory; ensuring that the roller slides at a uniform speed in the straight groove section and turns smoothly in the arc groove section, eliminating the jamming and impact caused by the rollers squeezing each other or the trajectory deviation, and improving the stability of the slider movement.

[0014] 3. Titanium nitride material has the characteristics of high hardness and low coefficient of friction, which can effectively resist the wear caused by long-term rolling of the rollers; the sealing gasket adopts a double sealing lip structure, which fits tightly with the base and end cap, and can prevent external dust, coolant and other impurities from entering the circulation track.

[0015] 4. The one-way valve oil injection nozzle set in the center of the end cap is directly connected to the arc groove of the circulating track. The injected grease can be evenly distributed along the track to the straight groove, arc groove and roller surface. Compared with traditional open lubrication, this structure can ensure that the grease is continuously attached to the friction surface, reducing dry friction between the roller and the track. Combined with wear-resistant coating and sealing design, the overall service life of the slider is improved. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: an integral racetrack-type circulating roller slide block, including a first base 1 and a second base 2. Both the first base 1 and the second base 2 are rectangular plates, symmetrically distributed front and back, with the second base 2 butt-fitted to the top of the first base 1. Sealing gaskets 3 are installed at both ends of the first base 1 and the second base 2, and end caps 4 are installed on the outer sides of the two sealing gaskets 3. A circulating track 5 is provided between the first base 1, the second base 2, the two sealing gaskets 3 and the two end caps 4. Several rollers 6 are installed in an orderly manner in the circulating track 5. Through the integrated design of the first base 1 and the second base 2 symmetrically fitted front and back, combined with the sealing gaskets 3 and end caps 4, a stable overall frame is constructed. Compared with the traditional split structure, it greatly reduces the assembly links of multiple parts, reduces assembly errors from the source, and lays a structural foundation for improving the accuracy of the slider movement.

[0019] like Figure 2 As shown, the circulating track 5 consists of two straight grooves and two arc grooves. The two straight grooves are located between the sides of the first base 1 and the second base 2 that are in contact with each other. One of the straight grooves extends to the front side of the first base 1 and the second base 2. The two arc grooves are respectively located inside the sealing gaskets 3 and end caps 4 at both ends of the first base 1 and the second base 2. The two arc grooves are respectively connected to the two ends of the two straight grooves to form an elliptical circulating track 5. The circulating track 5 is designed as an elliptical structure composed of straight grooves and arc grooves. The straight grooves and arc grooves are precisely connected, and the track joints are smoothly transitioned, eliminating the gap problem of traditional split tracks. This makes the circulation path of the roller 6 smoother. It can slide at a uniform speed in the straight groove section and turn smoothly in the arc groove section. This effectively solves the problem of easy jamming and impact when the roller 6 turns and circulates in traditional sliders, and significantly improves the stability and response speed of the slider movement.

[0020] like Figure 1 and Figure 3 As shown, the bottom of the joint between the first base 1 and the second base 2 is provided with an opening that communicates with the straight groove below the circulating track 5. The side wall of the roller 6 can extend through the opening, allowing the roller 6 to contact the external transmission components more directly and efficiently, reducing energy loss in the power transmission process and improving transmission efficiency. This design ensures that the slider can quickly respond to external drives in precision mechanical transmission, better meeting the requirements of high-end equipment for transmission timeliness and accuracy.

[0021] like Figure 3 As shown, the inner walls of the straight grooves on the sides of the first substrate 1 and the second substrate 2 are provided with wear-resistant coatings 7. The wear-resistant coating 7 is a titanium nitride coating. Titanium nitride has the characteristics of high hardness and low coefficient of friction, which can effectively resist the wear caused by the long-term rolling of the roller 6, extend the service life of the circulating track 5, and at the same time reduce the frictional resistance between the roller 6 and the circulating track 5, making the roller 6 run more smoothly, further improving the motion accuracy and stability of the slider, and meeting the needs of long-term and efficient operation of high-end equipment.

[0022] like Figure 2 and Figure 3 As shown, sealing rings that fit against the rollers 6 are provided on both sides of the inner wall of the circulating track 5. The sealing rings are made of nitrile rubber. The nitrile rubber sealing rings fit against the rollers 6, which not only prevents the leakage of grease in the circulating track 5 and ensures the lubrication effect, but also isolates external moisture, dust and other impurities from entering the circulating track 5, avoiding wear of the rollers 6 and the circulating track 5 due to the intrusion of impurities, extending the service life of the slider and improving the reliability of operation.

[0023] like Figure 1As shown, 2*3 neatly distributed positioning holes are provided at both ends of the first base 1 and the second base 2, as well as on the sides of the sealing gasket 3 and the end cover 4. Positioning pins 8 are threaded into the corresponding positioning holes. By providing 2*3 neatly distributed positioning holes at both ends of the first base 1 and the second base 2, as well as on the sides of the sealing gasket 3 and the end cover 4, and using positioning pins 8 for positioning, precise docking of each component is achieved. This ensures the coaxiality and parallelism between the first base 1, the second base 2, the sealing gasket 3, and the end cover 4, avoids the deviation of the running trajectory of the roller 6 due to assembly deviation, further improves the motion accuracy of the slider, and meets the requirements of CNC machine tools, high-precision testing equipment, and other high-precision components.

[0024] like Figure 1 As shown, one-way valve grease nipples 9 are provided at the center of the sides of both end caps 4, and the two one-way valve grease nipples 9 are respectively connected to the arc grooves at both ends of the circulating track 5. The end caps 4 are made of copper. The injected grease can be evenly distributed along the circulating track 5 to the straight groove, arc groove and roller 6 surface, realizing comprehensive and continuous lubrication of the circulating track 5 and roller 6. This structure can ensure that the grease is continuously attached to the friction surface, reduce the dry friction between the roller 6 and the circulating track 5, significantly reduce the degree of wear, and greatly extend the overall service life of the slider. The end caps 4 are made of copper, which can not only meet the required strength of the end caps 4, but also provide additional functions such as heat dissipation, rust prevention, conductivity and low wear, making them suitable for scenarios with high comprehensive performance requirements.
