Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, specifically to a ring-shaped guide rail with a positioning device. Background Technology

[0002] The circular guide rail with positioning device is a modular conveying device based on a closed-loop track design. It typically consists of a track body, a slide unit, a transmission system, and a positioning device. During operation, a servo motor receives pulse signals to drive a synchronous pulley, moving the slide to the vicinity of the target workstation. Simultaneously, a laser calibrator adjusts the flatness and straightness of each track segment. Combined with the error compensation function of the positioning device, seamless connection between different sections of the track is achieved. Circular guide rails with positioning devices are widely used in new energy manufacturing, semiconductor packaging, medical automation, and intelligent warehousing.

[0003] For example, Chinese patent CN210372704U, entitled "A Slide Rail," includes an outer rail, an inner rail, balls, and a ball retainer. The outer rail has a U-shaped cross-section and a groove along its length. The inner rail extends into the groove, and a plurality of balls are disposed within the groove and between the outer and inner rails. The ball retainer is formed by folding a first wear-resistant metal strip in half. When unfolded, the first wear-resistant metal strip includes a first strip portion and a second strip portion, with corresponding first and second ball holes respectively provided on the first and second strip portions. The first and second bead holes have a minimum diameter smaller than the diameter of the ball. When the first wear-resistant metal strip is folded in half, the corresponding first and second bead holes respectively fit the same ball from two opposite directions. After the first wear-resistant metal strip is folded in half, the first strip portion and the second strip portion are fixedly connected, and the ball is wrapped between the first strip portion and the second strip portion and is rotatably disposed in the corresponding first and second bead holes. The folding line on the first wear-resistant metal strip for the folding is arranged along the direction of the groove.

[0004] While the existing technologies can achieve slide rail installation, in practical use, on the one hand, the precision of slide rail assembly is not high enough. By attaching multiple slide rail segments together and installing them on the base, misalignment can easily occur at the slide rail connection points, thus affecting the operation of the slide block. On the other hand, it is difficult to install slide rails of different sizes on the base. Usually, the threaded holes on the base and the slide rail correspond to each other, which means that different bases are required when changing slide rails of different sizes, thus reducing the adaptability of the base. Therefore, it does not meet the current needs. To address this, we propose a ring guide rail with a positioning device. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can position the slide rail during assembly by using the first positioning block and the second positioning groove. When the slide rail is installed, the third slide rail is placed on the fixed frame. The operator holds the first slide rail and the second positioning block on the first slide rail corresponds to the first positioning groove on the third slide rail. At this time, the first slide rail is moved downward so that the second positioning block enters the first positioning groove and is locked in place with the first positioning groove. At the same time, the second through hole on the first slide rail corresponds to the second fixed cavity. Then the operator holds the second slide rail and the second positioning groove on the second slide rail corresponds to the first positioning block on the third slide rail. At this time, the second slide rail is moved downward until the first positioning block is locked in place with the second positioning groove, thereby improving the accuracy of the slide rail installation.

[0015] (2) This utility model can install slide rails of different sizes through the second fixed cavity and the first fixed cavity. Before installing the slide rail, the third slide rail is placed on the fixed frame according to the actual needs, and the first through hole on the third slide rail corresponds to the position of the first fixed cavity. Then the third slide rail is fixed. After the third slide rail is fixed, the first slide rail and the second slide rail are placed on the fixed frame, and the second through hole on the first slide rail and the second slide rail corresponds to the position of the second fixed cavity. At this time, the first slide rail and the second slide rail are fixed by the second bolt and the second nut, thereby improving the adaptability of the fixed frame to slide rails of different sizes.

[0016] (3) The present invention can fix the slide rail by means of the first bolt and the second bolt. When the slide rail is installed, the third slide rail has been placed on the fixing frame. At this time, the operator first puts the first nut into the first through hole and the first nut is locked and fixed with the first through hole. At this time, the operator aligns the first bolt with the lower opening of the first fixing cavity and inserts it into the first fixing cavity. Then the operator rotates the first bolt until the first bolt is moved to the appropriate position. At this time, the first bolt passes through the first nut and contacts the lower end of the fixing frame. When the first slide rail and the second slide rail are fixed, the operator puts the second nut into the second through hole and the second nut is locked and fixed with the second through hole. At this time, the operator aligns the second bolt with the lower opening of the second fixing cavity and inserts it into the second fixing cavity. Then the operator rotates the second bolt until the second bolt is moved to the appropriate position. At this time, the second bolt passes through the second nut and contacts the lower end of the fixing frame, thereby improving the flexibility of slide rail fixing. Attached Figure Description
