Description

Technical Field

[0001] The present application belongs to the field of automobile welding, and in particular, relates to a sliding mechanism. Background Art

[0002] At present, some workstations are equipped with an upper slide and a lower slide, one of which is used to slide and transport the workpiece. However, when a longer sliding stroke is required, the existing standard cylinders are difficult to meet this demand, because the standard cylinder stroke is within 2 meters, and non-standard customized cylinders are required or the overall mechanism is changed to a servo motor mechanism. Non-standard customized cylinders and servo motor mechanisms are expensive, have a long delivery time, and the subsequent maintenance costs are also high. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings in the prior art, the purpose of the present application is to provide a sliding mechanism with a simple and compact structure, which can meet the long stroke requirements of the slide table and can be met by using a standard cylinder, thereby reducing costs.

[0004] The technical means adopted by this application to solve the above technical problems are:

[0005] The present application provides a sliding mechanism, comprising:

[0006] Pedestal;

[0007] Slide rails arranged opposite to each other, the slide rails being mounted on the base;

[0008] A cylinder, wherein the cylinder is mounted on the base;

[0009] a gear rotatably mounted on the telescopic rod of the cylinder;

[0010] A fixed rack, the fixed rack is mounted on the base, and the fixed rack is meshed with the gear;

[0011] A slide table, the slide table being slidably mounted on the slide rail;

[0012] A movable rack, the movable rack being mounted on the slide, and the movable rack being meshed with the gear;

[0013] The cylinder drives the gear to extend and retract along the direction of the slide rail, the rotation of the gear drives the movable rack to move along the direction of the slide rail, and the movable rack drives the slide table to move along the slide rail.

[0014] Preferably, it also includes a fixing platform, and the fixing platform is installed on the slide rail.

[0015] Preferably, the positioning module is installed on the base, and the positioning module is located at one end of the slide rail.

[0016] Preferably, the fixed rack and the movable rack have the same length.

[0017] Preferably, the length of the fixed rack is 0.5-2m.

[0018] Preferably, the telescopic length of the cylinder is 0.5-2m.

[0019] Compared with the prior art, the sliding mechanism of the present application is provided with a gear, a fixed rack and a sliding rack, and the gear is driven to move by the cylinder. Because the fixed rack is meshed with the gear, when the gear moves, the gear will rotate, and then the gear drives the sliding rack to move, and the sliding rack drives the slide to slide along the slide rail. In this way, the maximum sliding stroke of the slide is equal to the telescopic length of the cylinder plus the length of the sliding rack. The standard cylinder can meet the large stroke requirement of the slide. The overall structure is simple and compact, which reduces the cost. BRIEF DESCRIPTION OF THE DRAWINGS
