Abstract
Description
Technical Field
[0001] This utility model belongs to the field of linear guide slider technology, specifically relating to a heavy-duty roller slider with an improved assembly structure. Background Technology
[0002] Linear guide slider mechanisms are increasingly being used in various fields of modern machinery industry, and some requirements such as high load, harsh environment, and high linear speed are also emerging.
[0003] The prior art, patent publication number CN216077966U, describes a heavy-duty roller slider. This patent involves mounting the slider on a platform or bracket via a guide rail. The roller is mounted in a long hole on the slider via a roller pin, which is fixed in place by a set screw. The roller surface contacts the guide rail surface. A follower is attached to the follower hole on the slider, and the follower surface rolls in contact with the guide rail surface. The followers are divided into two groups with their axes at a certain angle to prevent the slider from detaching from the guide rail. The followers on both sides of the slider and the roller roll in contact with the guide rail surface from three directions. The roller and guide rail have line-to-line contact, resulting in a larger contact area and a higher allowable maximum load. This solves the problem of the steel ball having a small point-to-line contact with the guide rail, leading to a smaller load capacity. However, in practical use, the following shortcomings remain: While the patent uses needle roller bearings for improvement, it still employs angled hole machining and a nut locking structure for installation and positioning. This process presents difficulties in assembly, risks of loosening, and potential safety hazards.
[0004] Therefore, there is a need for a heavy-duty roller slider with an improved assembly structure to solve the problems of assembly difficulties and loosening risks in the operation process of the existing technology. Utility Model Content
[0005] The purpose of this invention is to provide a heavy-duty roller slider with an improved assembly structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a heavy-duty roller slider with an improved assembly structure, comprising a guide rail and a slider, wherein the slider slides on the guide rail, the slider has a mounting hole, a roller is disposed in the mounting hole, a roller pin is fixedly connected to the roller, the roller pin has a corresponding pin hole in the slider, the roller pin is rotatably disposed in the pin hole, an improved mechanism is provided on the left and right sides of the slider for limiting the sliding of the slider, a set screw is provided on the slider, the set screw has a corresponding positioning hole in the slider, the set screw limits the roller pin in the positioning hole.
[0007] It should be noted in the solution that the improved mechanism includes a needle roller bearing, a screw, a socket, and a threaded hole. The screw is mounted on the needle roller bearing, the socket is opened through the slider, and the threaded hole is located outside the socket. The needle roller bearing is locked and limited within the socket and the threaded hole by the screw.
[0008] It is worth noting that the needle roller bearing is coated with anti-loosening adhesive.
[0009] Compared with the prior art, the heavy-duty roller slider with improved assembly structure provided by this utility model has at least the following beneficial effects:
[0010] (1) By setting an improved mechanism on the slider, the needle roller bearing is installed on the slider through the insertion hole, and the needle roller bearing is locked and limited by the screw and the threaded hole. This operation shortens the processing time, reduces the number of parts, improves the assembly efficiency and accuracy, enhances the locking strength, is suitable for automated assembly, and reduces maintenance costs.

[0015] The present invention will be further described below with reference to the embodiments.
[0016] Please see Figure 1-3 This utility model provides a heavy-duty roller slider with an improved assembly structure, including a guide rail 1 and a slider 2. The slider 2 slides on the guide rail 1. The slider 2 has a mounting hole 4, and a roller 3 is installed in the mounting hole 4. A roller pin 301 is fixedly connected to the roller 3. The roller pin 301 has a corresponding pin hole 302 in the slider 2. The roller pin 301 is rotatably installed in the pin hole 302. Improved mechanisms 5 are provided on the left and right sides of the slider 2 to limit the sliding of the slider 2. A set screw 6 is provided on the slider 2. The set screw 6 has a corresponding positioning hole 601 in the slider 2. The set screw 6 limits the roller pin 301 in the positioning hole 601.
[0017] Further as Figure 2 and Figure 3 As shown, it is worth noting that the improved mechanism 5 includes a needle roller bearing 501, a screw 502, a socket 503, and a threaded hole 504. The screw 502 is mounted on the needle roller bearing 501. The outside of the needle roller bearing 501 is coated with anti-loosening adhesive to prevent it from falling off during operation. The socket 503 is opened through the slider 2. The threaded hole 504 is located outside the socket 503. The needle roller bearing 501 is locked and limited in the socket 503 and the threaded hole 504 by the screw 502.
[0018] The needle roller bearing 501 is inserted into the slider 2 through the insertion hole 503, and the needle roller bearing 501 is locked and limited by the screw 502 and the threaded hole 504. Through the above operations, the assembly efficiency and accuracy are improved, while the locking strength is increased, which is suitable for automated assembly and reduces maintenance costs.
[0019] This solution has the following working process: When this device is in use, the needle roller bearing 501 is inserted into the slider 2 through the insertion hole 503, and the needle roller bearing 501 is locked and limited by the screw 502 and the threaded hole 504. Through the above operations, the assembly efficiency and accuracy are improved, while the locking strength is increased, which is suitable for automated assembly and reduces maintenance costs. Through the cooperation of the needle roller bearing 501 and the roller 3, the slider 2 slides stably on the guide rail 1, thereby improving the connection stability of the slider 2 sliding.
[0020] In summary, the improved mechanism 5 on the slider 2 allows the needle roller bearing 501 to be installed on the slider 2 through the insertion hole 503, and the needle roller bearing 501 is locked and limited by the screw 502 and the threaded hole 504. This operation shortens the processing time, reduces the number of parts, improves assembly efficiency and accuracy, enhances locking strength, is suitable for automated assembly, and reduces maintenance costs.
