Description

Technical Field

[0001] The utility model belongs to the technical field of metal guide rails, and in particular relates to a cross roller guide rail retainer. Background Art

[0002] Crossed roller guideway cages drive linear motion by forming a guideway pair. They are widely used in the field of metalworking technology. By assembling them to form a guideway pair, they allow the metal to move in a straight line during machining, ensuring the best possible machining results.

[0003] There are various types of cross roller guide rail cages in the prior art. Generally, they are composed of a guide rail body, which is relatively arranged with a roller installed in the middle. The roller rotates when the guide rail moves. In the prior art, bolts are installed at both ends of the guide rail body. The roller is limited by the bolts at both ends during movement. However, the rigidity of the bolts is not strong and the limiting effect of the roller cannot be guaranteed. In order to solve this problem, Chinese utility model CN217381305U discloses a limit-reinforced cross roller guide rail cage. The guide rail includes a guide rail body, which is a group of two guide rail bodies. Each guide rail body is provided with a slide groove. The slide grooves of the two guide rail bodies are arranged relative to each other, and rotating rollers are arranged in the two slide grooves. When the guide rail bodies slide relative to each other, the rotating roller can move in the two slide grooves at the same time, and the axis of each slide groove is closed at both ends. The roller is limited by the closed structure at both ends of the slide groove, thereby improving the precise guiding function of the roller, increasing the strength of the limit, and avoiding the limit from being damaged, thereby improving the performance of the cross roller guide rail cage.

[0004] Although the above-mentioned slide groove can better limit the roller through the closed structure at both ends, the above-mentioned cross roller guide rail retainer still has the following defects during use. Since the slide groove is opened on the guide rail body, the length of the slide groove is fixed. When the guide rail body moves relatively, it is limited by the length of the slide groove. When the length of the slide groove is too long, the problem of excessive movement is likely to occur.

[0005] To this end, the utility model provides a cross roller guide rail retainer, so that the length of the slide groove can be adjusted to solve the above problem. Utility Model Content

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0037] like Figures 1 to 3As shown, it is a schematic structural diagram of the cross roller guide rail cage in this embodiment. The cross roller guide rail cage in this embodiment includes two guide rail bodies 100 arranged opposite to each other and a roller assembly 200 located in the middle of the guide rail body 100. In this embodiment, the guide rail bodies 100 can slide relative to each other. In this embodiment, the guide rail body 100 includes a fixed shell 101, and a slide groove 102 is provided on the opposite side of the fixed shell 101 along the axial direction of the fixed shell 101. In this embodiment, the roller assembly 200 includes a cage 201, and a plurality of roller bodies 202 are rotatably mounted on the cage 201. Figure 4 As shown, in this embodiment, the roller body 202 is a cylindrical structure, and the roller body 202 is installed on the retaining frame 201 at an angle, and the inclination angle of the roller body 202 is 45°. It is worth noting that the roller body 202 in this embodiment is staggered and inclined on the retaining frame 201. In addition, the slide groove 102 in this embodiment is a V-shaped slide groove, wherein the V-shaped angle is 45°. When the guide rail bodies 100 are relatively arranged, the retaining frame 201 is located between the guide rail bodies 100, and the tops of the two ends of the roller body 202 on the retaining frame 201 are located in the slide groove 102.

[0038] When the cross roller guide rail retainer in this embodiment is in use, the guide rail body 100 is installed on the load. When the load moves, it drives the guide rail body 100 to move, and the roller body 202 between the guide rail bodies 100 rotates in the slide groove 102, thereby ensuring the smooth movement of the guide rail body 100 and allowing the load to move linearly.

[0039] In addition, if Figure 5 As shown, both ends of the guide rail body 100 in this embodiment are closed structures, that is, both ends of the slide groove 102 in this embodiment are closed structures. When the roller body 202 rolls in the slide groove 102, the roller body 202 is limited by the closed structure, avoiding the problem of bolt limitation in the prior art that is prone to collision and damage with the roller body 202.

[0040] In this embodiment, in order to avoid the problem of excessive movement caused by the length of the slide groove 102 when the guide rail body 100 moves, a sliding plate 103 is slidably installed in the slide groove 102. The distance between the sliding plates 103 is the length of the slide groove 102, and an adjustment component 104 is also installed on the side of the sliding plate 103 opposite to the end of the guide rail body 100. Figure 5 as well as Figure 6As shown, the position of the sliding plate 103 is adjusted by the adjustment component 104, and the length of the slide 102 can be adjusted. In this embodiment, the adjustment component 104 includes a threaded rod 104b installed on the sliding plate 103 and a rotating cylinder 104a sleeved on the threaded rod 104b and threadedly assembled with the threaded rod 104b. The rotation of the rotating cylinder 104a can drive the threaded rod 104b to move along the length direction of the rotating cylinder 104a, and then drive the sliding plate 103 to move to adjust the distance between the sliding plates 103, and then adjust the length of the slide 102. In this embodiment, the end of the rotating cylinder 104a An adjusting button 104c is also rotatably installed, and the adjusting button 104c is rotatably installed on the inner wall of the end of the slide groove 102. In this embodiment, when it is necessary to adjust the distance between the sliding plates 103, the adjusting button 104c is rotated to drive the rotating cylinder 104a to rotate, and then the threaded rod 104b can be driven to move and drive the sliding plate 103 to slide in the slide groove 102, so that the distance between the sliding plates 103 can be adjusted. The roller assembly 200 is installed in the slide groove 102 between the sliding plates 103, so that the roller assembly 200 is restricted by the slide groove 102, thereby avoiding the problem of excessive movement of the guide rail body 100.

[0041] like Figure 5 as well as Figure 6 As shown, in this embodiment, in order to facilitate the adjustment component 104 to adjust the position of the sliding plate 103, the adjustment component 104 in this embodiment also includes a fixed cylinder 104d, one end of the fixed cylinder 104d is assembled on the inner wall of the end of the slide groove 102, and the end of the fixed cylinder 104d is open and the interior is hollow, and a connecting rod 104e is slidably installed inside the fixed cylinder 104d, and the end of the connecting rod 104e is connected to the sliding plate 103. In this embodiment, when the rotating cylinder 104a is rotated to drive the threaded rod 104b to move and drive the sliding plate 103 to move, the connecting rod 104e slides relative to the fixed cylinder 104c, thereby facilitating the adjustment component 104 to adjust the position of the sliding plate 103.

[0042] like Figure 7 as well as Figure 8 As shown, in this embodiment, a giveway groove 102a is further provided at the bottom of the slide groove 102, and the giveway groove 102a is connected to the cavity in the slide groove 102. When the roller body 202 is located in the slide groove 102, there is a gap between the top of the two ends of the roller body 202 and the giveway groove 102a, thereby effectively avoiding friction between the slide groove 102 and the top of the two ends of the roller body 202, ensuring the integrity of the roller body 202, so as to adapt to the rolling of the guide rail body 100 when moving. In addition, the setting of the giveway groove 102a has the purpose of accommodating lubricating oil. The lubricating oil is located in the giveway groove 102a, which can play the purpose of effective lubrication and ensure the smooth movement of the guide rail body 100.

[0043] It is worth noting that the lubricating oil in this embodiment enters the clearance groove 102a through the cavity between the sliding plate 103 and the end of the chute 102, and flows from the clearance groove 102a to the chute 102 between the sliding plates 103, thereby achieving the purpose of lubrication. However, when the lubricating oil contains other impurities and enters the clearance groove 102a, it is easy to rub against the roller body 202, causing the roller body 202 to be unable to rotate efficiently, causing certain interference with the movement of the guide rail body 100. In order to solve this problem, Figures 8 to 11 As shown, an extension plate 103a is further provided at the bottom of the sliding plate 103 in this embodiment, and a filter hole is opened on the extension plate 103a. When the lubricating oil enters the give way groove 102a from the cavity between the sliding plate 103 and the end of the slide groove 102, the lubricating oil passes through the filter hole and enters the slide groove 102 between the sliding plates 103. The extension plate 103a plays a filtering role, filtering impurities in the lubricating oil, so that the impurities are trapped in the cavity between the sliding plate 103 and the end of the slide groove 102, avoiding the impurities from contacting the roller body 202, ensuring the rotation effect of the roller body 202, thereby facilitating the movement of the guide rail body 100 and making the load movement effect smoother.

[0044] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
