Description

Technical Field

[0001] The utility model relates to the technical field of mechanical automation, in particular to a double-track docking platform with adjustable track gauge. Background Art

[0002] A docking station is a type of transport equipment that transports semi-finished products from one processing equipment to another. The docking station plays the role of transporting items in the production line, thus ensuring the circulation and integrity of the entire assembly line. The double-track docking station has a docking station with two-way tracks. The double-track docking station can adjust the direction of transportation, which is convenient for people to use and makes the docking station more adaptable. The existing PCB board double-track docking station cannot adjust the track plate during use.

[0003] In view of this, the Chinese patent document with authorization number CN217147450U discloses a double-track docking station for electronic production, including a power control box and a track plate. Sliding rods are symmetrically arranged between the power control boxes, and the track plate is slidably connected to the sliding rods. A column hole is opened in the middle of the track plate, and a screw rod is passed through the column hole. A threaded driving structure is installed on the track plate, and the threaded driving structure includes a fixed bracket, a cylinder, an internal thread clamp, and a limit card installed on the track plate; the rotation of the screw rod is controlled by the power control box. When the cylinder drives the telescopic rod to move downward, the dynamic pull rod pushes the upper end of the internal thread clamp to both sides, so that the internal thread clamp clamps the screw rod through the fixed shaft. Under the action of the internal thread wall, the internal thread clamp drives the corresponding track plate to move along the screw rod, thereby adjusting the spacing of the track plates; however, each track plate needs to be equipped with a cylinder to drive and control the opening and closing of the internal thread clamp. Not only is the structure relatively complex, but the internal thread clamp is prone to wear and tear with the rotating screw rod during the closing process, affecting the service life; in addition, the frequency of needing to adjust the track spacing is not high, and the cost of configuring multiple cylinders is high.

[0004] Therefore, it is necessary to improve the above shortcomings of the prior art. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a double-track docking platform with adjustable track gauge, which has a simple structure, a long service life and a low cost, in view of the deficiencies of the above-mentioned prior art.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a double-track docking platform with adjustable track gauge, comprising a workbench, a first bracket and a second bracket respectively installed at both ends of the workbench, a fixed rail, a first movable rail, a second movable rail and a third movable rail installed on the first bracket are sequentially arranged between the first bracket and the second bracket, the fixed rail, the first movable rail, the second movable rail and the third movable rail are all provided with a transmission mechanism for transmitting materials, the fixed rail and the first movable rail are a first group of rails, the second movable rail and the third movable rail are a second group of rails, a first screw rod spirally driven with the first movable rail, a second screw rod spirally driven with the second movable rail and a third screw rod spirally driven with the third movable rail are rotatably connected between the first bracket and the second bracket, and one end of the first screw rod, the second screw rod and the third screw rod are all provided with a screw driving mechanism.

[0007] By adopting the above technical solution, when it is necessary to adjust the distance between the fixed rail and the first movable rail, the first movable rail can be spirally driven by the screw drive mechanism set at the first screw rod to drive the first screw rod to rotate forward and reverse, so as to make the first movable rail closer to or away from the fixed rail, thereby realizing the adjustment of the distance between the first group of rails; similarly, the adjustment of the distance between the second group of rails is achieved by driving the screw drive mechanism corresponding to the second screw rod or the third screw rod to rotate to change the position of the second movable rail or the third movable rail, thereby realizing the adjustment of the distance and position of the second group of rails; the above technical solution for adjusting the track gauge is not only simple in structure, but also has a long service life because the movable rail and the screw rod are always in a meshing and matching spiral transmission mode; since there is no need to configure multiple cylinders for separate control, the cost is relatively low.

[0013] By adopting the above technical solution, when adjusting the position of the first movable rail, the rotation of the first screw rod will drive the first linkage screw rod to rotate synchronously, thereby driving the first movable rail to move from both ends of the first movable rail, further improving the stability and accuracy of the displacement; the same applies when adjusting the position of the second movable rail and the third movable rail, which will not be repeated.

[0014] The above technical solution is further configured as follows: a chain transmission is performed between the first linkage screw rod and the first screw rod, a chain transmission is performed between the second linkage screw rod and the second screw rod, and a chain transmission is performed between the third linkage screw rod and the third screw rod.
