Description

Technical Field

[0001] The present invention belongs to the technical field of guide rails, and particularly relates to a circular guide rail structure. Background Art

[0002] Circular roller guidance is a product designed to overcome the disadvantages of traditional linear bearings and provide excellent performance in high-speed driving and high-load environments. This product is specially designed to enable linear motion with low noise even at high speeds.

[0003] Traditional linear bearings use a method similar to a playground track to make the balls circulate in a straight-line rotation manner. However, this structure has the disadvantage that the balls hit the retainer and generate noise at high speeds. Especially, the faster the linear motion, the greater the noise. In addition, in an environment with more dust, impurities may accumulate in the retainer grooves, interfering with the rotation of the balls and causing the retainer to break.

[0004] To overcome these problems, circular roller guidance emerged. It uses circular rollers instead of a track structure to enable linear motion. This can greatly reduce noise and minimize impurity accumulation. In addition, different from conventional linear bearings that need to be regularly lubricated, circular roller guidance provides a practical solution that can be effectively used without lubrication injection.

[0034] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0035] The structure of the present invention is described in detail below with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figures 1 to 2As shown in the figure, a circular guide rail structure provided by an embodiment of the present invention includes a guide rail structure for guiding. A conveying component for moving and limiting is arranged on the surface of the guide rail structure. The inside of the conveying component is used in cooperation with the surface of the guide rail structure. The guide rail structure includes a guide rail 1 for guiding the conveying component. A plane is provided at the top of the guide rail 1. A support base 2 is arranged at the bottom of the guide rail 1. A first bolt 3 is arranged at the bottom of the support base 2. The threaded end of the first bolt 3 penetrates through the support base 2 and extends into the inside of the guide rail 1. The conveying component includes a slider 4. The slider 4 is sleeved on the surface of the guide rail structure. Installation screw holes 5 are respectively arranged at the four corners of the top of the slider 4. A first roller 6 is movably connected to the top of the slider 4. The number of the first rollers 6 is two. Second rollers 7 are detachably connected to the front side and the rear side of the left and right sides of the slider 4. The surface of the second roller 7 is used in cooperation with the surface of the guide rail structure. A lock block 9 is arranged at the front side of the slider 4. The lock block 9 is used in cooperation with the plane. A third bolt 10 is arranged at the front side of the lock block 9. The threaded end of the third bolt 10 penetrates through the lock block 9 and extends into the inside of the slider 4. The first roller 6 and the second roller 7 adopt a double-layer V-shaped rubber sealing structure.

[0038] Select needle roller first rollers 6 and second rollers 7 that can withstand high loads and design them in an environment where fine dust is generated or special chemical liquids are used to ensure their durability. This design concept is to add an automatic centering function to the needle roller first rollers 6 and second rollers 7, so that the inner and outer rings move 0.5 mm left and right to prevent fine dust or liquid from penetrating. However, if this phenomenon is ignored, the penetrated fine dust or liquid may cause contact between the first roller 6 and the second roller 7, damaging the retainer of the engineering plastic material, resulting in the inability of the first roller 6 and the second roller 7 to rotate, and ultimately causing the machine to stop running. Therefore, in order to prevent the gap between the first roller 6 and the second roller 7, a structure that can insert a double-layer V-shaped rubber seal is designed.

[0039] Adopting a technical design similar to that of a circular roller guide rail is required to be used in equipment with a large middle space. Through the design based on the left and right sides, the manufacturing efficiency is improved. For the guide rail 1, the installation holes can be designed in various ways. Generally, a circular roller guide rail usually connects the shaft with the first roller 6 and the second roller 7 through a point contact method. Since the contact surface of this design is relatively small, less noise is generated during high-speed operation. However, point contact and line contact may not be the most ideal conditions under high loads. Of course, since the surface hardness of the guide rail 1 usually reaches above HRC54, the phenomenon of easy wear is relatively less, but under high load conditions, the shaft may experience wear.

[0040] The design of this product is to solve the problems caused by the line contact of the roller contact surface at the upper part of the product shown in the previous figure. By machining the cross-section of the guide rail 1 into a plane, the problem of the contact surface between the first roller 6 and the second roller 7 being a surface contact is solved. At the same time, by minimizing the clearance tolerance between A and B, the design aims to prevent the tabletop from rotating in the left and right directions.

[0041] By minimizing the clearance between A and B, the left and right rotation range of the tabletop can be reduced. In order to adjust the tiny clearance, bolts are designed to fix the two first rollers 6 and the second roller 7. By making eccentric bolts, this clearance can be finely adjusted.

[0042] During use, first contact the guide rail 1 with the support base 2. Pass the first bolt 3 through the support base 2 and extend it into the interior of the guide rail 1 to complete the installation of the guide rail 1. Install the first roller 6 on the top of the slider 4, make the first roller 6 contact the plane on the top of the guide rail 1. Contact the second roller 7 with the surface of the guide rail 1, and fix the second roller 7 on the slider 4 through the second bolt 8. Snap the locking block 9 into the slider 4 and fix the locking block 9 through the third bolt 10, so that the bottom of the locking block 9 contacts the top plane of the guide rail 1 to achieve the purpose of limiting position. Install the structure to be guided into the installation screw holes 5 of the slider 4 for guiding the structure.

The transmission component includes a slider 4 sleeved on the surface of the guide rail structure. Installation screw holes 5 are provided at the four corners of the top of the slider 4. Two first rollers 6 are movably connected to the top of the slider 4. The second rollers 7 are detachably connected to the front and rear sides of the left and right sides of the slider 4. The surface of the second roller 7 is used in cooperation with the surface of the guide rail structure. A locking block 9 is arranged on the front side of the slider 4. The locking block 9 is used in cooperation with the plane. A third bolt 10 is arranged on the front side of the locking block 9. The threaded end of the third bolt 10 passes through the locking block 9 and extends into the interior of the slider 4.

[0045] By machining three surfaces of the guide rail 1 and making it contact the surfaces of the first roller 6 and the second roller 7 at three points, a structure that completely eliminates left and right rotation is designed.

[0046] With this guiding rail 1 design structure, various shaped table tops can be designed, such as circular, quadrilateral, triangular, etc., products with spline functions.

[0047] In addition, by removing the lower support frame and installing a structure that can support or rotate using both ends of the shaft, a system with spline functions can be constructed to achieve the functions of fixing or rotating.

[0081] The conventional standard needle roller first roller 6 and second roller 7 can be eliminated, allowing the outer ring to be machined into various shapes. The outer ring can be made of a variety of lubricating stainless steels or special engineering plastics. If the outer ring is made of a contoured engineering plastic, the design allows for the elimination of the need for a separate inner ring. However, if the outer ring must be made of steel or special stainless steel, the design incorporates carbon fiber capable of withstanding shock loads of 300 kg / f or 600 kg / f and special engineering plastics with solid lubricity, simplifying the design and reducing costs without the use of lubricants.

By introducing clearance tolerances in the inner diameters of the upper first and second rollers 6 and 7 and the pins securing them, automatic left and right centering of the first and second rollers 6 and 7 is achieved.

[0083] This design helps to reduce noise, improve the stability of the first roller 6 and the second roller 7, and prevent the rollers from falling off under different straightness error conditions.

[0084] This newly designed circular roller guide improves this problem, making it possible to prevent left and right rotation when only one track is used, thus improving its practicality.

[0087] like Figure 12 、 Figure 13 and Figure 14 As shown, an embodiment of the present invention provides a circular guide rail structure, including a guide rail structure for guiding, a conveying component for moving and limiting is provided on the surface of the guide rail structure, the interior of the conveying component cooperates with the surface of the guide rail structure, the guide rail structure includes a guide rail 1 for guiding the conveying component, a support seat 2 is provided at the bottom of the guide rail 1, the conveying component includes a slider 4, the slider 4 is sleeved on the surface of the guide rail structure, the four corners of the top of the slider 4 are provided with mounting screw holes 5, the top of the slider 4 is movably connected to a first roller 6, the number of the first roller 6 is two, the front and rear sides of the left and right sides of the slider 4 are detachably connected to the second roller 7, the surface of the second roller 7 cooperates with the surface of the guide rail structure, and the surfaces of the first roller 6 and the second roller 7 are both provided with grooves.

[0088] Designing the product's rollers for two-point contact also prevents them from disengaging due to straightness errors when installing the left and right guide rails, allowing the first and second rollers 6 and 7 to move left and right based on straightness deviations. By introducing clearance tolerances in the inner diameters of the upper first and second rollers 6 and 7 and the pins securing them, automatic left and right centering of the first and second rollers 6 and 7 is achieved.

[0089] This design helps to reduce noise, improve the stability of the first roller 6 and the second roller 7, and prevent the rollers from falling off under different straightness error conditions.

[0090] This newly designed circular roller guide improves this problem, making it possible to prevent left and right rotation when only one track is used, thus improving its practicality.

[0091] When in use, first install the first roller 6 on the top of the slider 4 so that the first roller 6 contacts the plane on the top of the guide rail 1. By making the second roller 7 contact the surface of the guide rail 1, the second roller 7 is fixed to the slider 4 through the second bolt 8, and the structure to be guided is installed in the mounting screw hole 5 of the slider 4 to guide the structure. This structure can install the support seat 2 at the position where it needs to be installed, and the slider 4 can rotate around the guide rail 1 at a certain angle.
