Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a rust-proof linear motion structure. Background Technology

[0002] During processing, workpieces need to be moved to relevant equipment for welding, painting, cold pressing, and other processes to die-cast them, such as die-casting car doors. They are then moved to other processes for polishing, grinding, rust removal, rust prevention, and painting. Currently, workpieces are placed on mobile frames during production. These frames can only move them below the corresponding equipment, requiring robotic arms and lifting devices to move them upwards. This operation is costly and occupies considerable space. Utility Model Content

[0003] To overcome at least one of the defects (deficiencies) of the prior art, this utility model provides a rust-proof linear motion structure that synchronizes horizontal and vertical motion, thereby improving work efficiency and reducing equipment costs.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a rust-proof linear motion structure, including a horizontal guide rail, a movable frame that can move on the horizontal guide rail, and a lifting mechanism that is lifted and lowered on the movable frame. There are two horizontal guide rails and two movable frames arranged symmetrically. The lifting mechanisms are symmetrically arranged on the inner sides of the two movable frames. A linkage mechanism is provided on the movable frame, which links the movable frame and the lifting mechanism and synchronously controls the movement of the movable frame and the lifting frame. The opposite sides of the lifting frame are provided with support blocks for supporting the workpiece.

[0005] The aforementioned rust-proof linear motion structure includes a linkage mechanism comprising a geared motor, linkage rollers, and linkage shaft mounted on a movable frame. The bottom of the movable frame is provided with translation rollers that roll on a horizontal guide rail. The two ends of the linkage shaft are respectively connected to two linkage rollers. The geared motor drives the translation rollers to move the translation frame horizontally. The geared motor synchronously drives the lifting mechanism to move up and down through the linkage rollers and linkage shaft.

[0006] In the aforementioned rust-proof linear motion structure, the lifting mechanism includes a lifting seat, and the top of the mobile frame is provided with a fixed roller. The fixed roller is connected to a connecting roller, and the lifting seat moves up and down on the mobile frame in conjunction with the connecting roller.

[0007] In the aforementioned rust-proof linear motion structure, the side wall of the movable frame is provided with a vertical guide rail, and the inner side of the lifting seat is provided with lifting rollers. The lifting seat can move up and down on the vertical guide rail via the lifting rollers.

[0008] In the aforementioned rust-proof linear motion structure, the side of the lifting seat is provided with a telescopic cylinder, which is connected to the support block and controls the lateral movement of the support block.

[0009] In the aforementioned rust-proof linear motion structure, the horizontal guide rail is provided with blocking blocks at both ends, and the moving frame is provided with limiting rods at both ends. The moving frame moves on the horizontal guide rail and is limited between the blocking blocks by contacting the blocking blocks through the limiting rods.

[0010] In the aforementioned rust-proof linear motion structure, a balance column is provided between the two moving frames.

[0011] The beneficial effects achieved by this utility model are: the moving frame and the lifting mechanism move synchronously, which can quickly move the workpiece to the processing station and improve work efficiency; the synchronous lifting and horizontal movements reduce the amount of related equipment needed to process the workpiece, saving costs and reducing space occupation.

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0016] Reference Figure 1-3 As shown, a rust-proof linear motion structure includes a horizontal guide rail 1, a movable frame 2 that is movable on the horizontal guide rail 1, and a lifting mechanism 3 that is lifted and lowered on the movable frame 2. There are two horizontal guide rails 1 and two movable frames 2 arranged horizontally and symmetrically. The lifting mechanisms 3 are symmetrically arranged on the inner sides of the two movable frames 2. The movable frame 2 is provided with a linkage mechanism 4, which links the movable frame 2 and the lifting mechanism 3 and synchronously controls the movement of the movable frame 2 and the lifting frame 3. The opposite sides of the lifting frame 3 are provided with support blocks 34 for supporting the workpiece.

[0017] The linkage mechanism 4 includes a geared motor 41, linkage rollers 42, and linkage shaft 43 mounted on the movable frame 2. The bottom of the movable frame 2 has translation rollers 21 that roll on the horizontal guide rail 1. Both ends of the linkage shaft 43 are connected to the two linkage rollers 42 respectively. The geared motor 41 drives the translation rollers 21 to move the movable frame 2 horizontally. The geared motor 41 synchronously drives the lifting mechanism 3 to move up and down via the linkage rollers 42 and linkage shaft 43. Specifically, when the geared motor 41 drives the translation rollers 21 to move the movable frame 2 horizontally, the geared motor 41 can be connected to the translation rollers 21 via a synchronous belt or transmission chain. This allows the drive shaft of the geared motor 41 to rotate synchronously, driving the translation rollers 21 to rotate, thereby achieving the horizontal movement of the movable frame 2 on the horizontal guide rail 1.

[0018] The lifting mechanism 3 includes a lifting seat 31. A fixed roller 22 is located at the top of the movable frame 2, and the fixed roller 22 is connected to a connecting roller 42. The lifting seat 31 moves up and down on the movable frame 2 via the connecting roller 42. A synchronous belt or chain can be wound between the fixed roller 22 and the connecting roller 42. The lifting motion of the lifting seat 31 can be achieved by connecting the lifting seat 31 to the synchronous belt or chain on one side. When the geared motor 41 drives the connecting roller 42 to rotate, the synchronous belt or chain performs a cyclical motion, driving the lifting seat 31 to move up and down.

[0019] The side wall of the mobile frame 2 is provided with a vertical guide rail 23, and the inner side of the lifting seat 31 is provided with a lifting roller 32. The lifting seat 31 can move up and down on the vertical guide rail 23 through the lifting roller 32.

[0020] The side of the lifting seat 31 is provided with a telescopic cylinder 33, which is connected to the support block 34 and controls the lateral movement of the support block 34.

[0021] The horizontal guide rail 1 has blocking blocks 11 at both ends, and the mobile frame 2 has limiting rods 24 at both ends. The mobile frame 2 moves on the horizontal guide rail 1 and is limited between the blocking blocks 11 by the limiting rods 24.

[0022] A balance column 25 is provided between the two mobile frames 2.

[0023] In a specific implementation of this utility model, the workpiece is placed on the support block 34, and the reduction motor 41 is started. The reduction motor 41 drives the translation roller 21 and the linkage roller 42 to rotate. The translation roller 21 drives the moving frame 2 to move on the horizontal guide rail 1. The linkage roller 42 and the fixed roller 22 drive the lifting seat 31 to move up and down synchronously through the synchronous belt or synchronous chain, so that the workpiece can move back and forth in the horizontal direction and move up and down in the vertical direction, thereby realizing the movement of the workpiece to the corresponding work position for operations such as spraying, die casting, and electric welding.

[0024] The positional relationships described in the figures are for illustrative purposes only and should not be construed as limiting this patent. Clearly, the above embodiments of this utility model are merely examples to clearly illustrate the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
