Description

Technical Field

[0001] The utility model relates to the technical field of intelligent welding systems, in particular to a cross track guide structure. Background Art

[0002] As a key component of the white body of a car, the door assembly plays a role in sealing and bearing, and needs to be able to bear a large number of functional parts and resist side impacts. Its manufacturing precision determines the strength, quality and appearance of the entire vehicle. The automobile manufacturing production line has long been automated, with a main track set between the processing warehouse and the storage warehouse, on which a tray containing parts is slidably connected, and then driven by a reduction motor to move the tray on the main track, thereby realizing the circulation and transportation of parts between the processing warehouse and the storage warehouse.

[0003] Usually, there are many specifications of vehicle body parts, so it is necessary to set up multiple different storage locations on both sides of the main track. The storage location has its own slide rail, and the slide rail intersects with the main track to form a cross. The material tray of the storage location can be moved to the main track via the slide rail, and then transported to the processing location along the main track for processing. In order to enable the material tray of the storage location to move to the correct position on the main track, or to enable the material tray to move smoothly from the main track to the slide rail to enter the storage location, it is usually necessary to set a guide mechanism at the connection between the main track and the slide rail. The guide wheel of the guide mechanism can push the material tray under the drive of the cylinder to align the material tray, so that the material tray can be accurately moved onto the main track or the slide rail. For example, the prior art "connecting rod guide mechanism" (publication number: CN202911838U) drives the connecting rod through the cylinder, thereby driving the guide wheel to push axially to achieve the guide limit of the material tray. However, the prior art still has the following technical problems:

[0004] In the guide mechanism of the prior art, connecting rod one, connecting rod two and the end of the cylinder piston rod are hinged, the other end of connecting rod two is hinged to the support seat, and the other end of connecting rod one is hinged to the stretching shaft. Then, a vertically arranged cylinder is used to drive connecting rod one and connecting rod two, so that the guide wheel mounting frame connected to the stretching shaft can achieve axial movement. The overall structure is complex, with many parts, which is not convenient for installation and maintenance.

[0005] The guide mechanism of the prior art is provided with a limit mechanism, which includes a proximity switch arranged on a mounting seat, which can identify the forward and backward positions of the guide wheel. However, the proximity switch is a sensor and needs to be connected with a wire. The proximity switch also needs to be fixed with a tool. However, there are many parts on the main track itself and the space is small. The wires of the proximity switch are easy to interfere with the parts, and the tooling for fixing the proximity switch also takes up a part of the space, making the installation and maintenance of the entire limit mechanism very inconvenient. Utility Model Content

[0006] The utility model provides a cross track guide structure, which can solve the problem that the limiting mechanism in the existing guide structure is not easy to install and maintain.

[0007] The present application provides the following technical solutions: A cross-track guide structure, comprising a mounting seat, a driving part detachably connected to the mounting seat, a transmission part hinged to the driving part, and a guide part hinged to the transmission part;

[0008] It also includes a limiting portion detachably connected to the guide portion; the limiting portion includes a mounting arm and a fixing block, the mounting arm includes an integrally formed rod portion and a head portion, the rod portion of the mounting arm is detachably connected to the guide portion, and the head portion of the mounting arm is provided with a groove;

[0009] The fixing block includes an integrally formed long arm and a short arm, which form an L shape. One end of the long arm away from the short arm is hinged to the guide part. A positioning groove is provided on the short arm, and a positioning block is detachably connected to the positioning groove. The positioning block can be embedded in the groove of the head of the mounting arm.

[0010] Beneficial effect: The driving part transmits the driving force to the guide part through the transmission part, thereby controlling the movement of the guide part. When the guide part moves into place, the positioning block is embedded in the groove, thereby preventing the mounting arm and the guide part connected to the mounting arm screw from continuing to move, so that the guide part can move accurately. The entire limiting part has a simple structure and is connected by screws for easy disassembly and assembly, making installation and maintenance more convenient.

[0011] Furthermore, the driving part includes two vertical plates fixed on the mounting base, the two vertical plates are arranged opposite to each other, the outer sides of the two vertical plates are respectively screwed to two baffles, the ends of the two baffles away from the vertical plates are screwed to a connecting plate, a protruding block is fixed on the side of the connecting plate facing the vertical plate, a cylinder is hinged on the protruding block, a mounting head is threadedly connected to the piston rod head of the cylinder, and the mounting head is hinged to the transmission part.

[0012] Beneficial effect: The cylinder piston rod can drive the transmission part to move, and the cylinder and the raised block are hinged instead of rigidly connected, which can prevent the cylinder from being damaged by the reverse thrust when the piston rod is extended when the cylinder is in motion.

[0013] Furthermore, the transmission part includes an active arm pivotally connected between two vertical plates, one acute-angle end of the active arm is pivotally connected to the mounting head, the other acute-angle end of the active arm is pivotally connected to a driven arm, and one end of the driven arm away from the active arm is pivotally connected to the guide part.

[0014] Beneficial effect: The active arm and the driven arm are both pivotally connected, and the cylinder piston rod can drive the active arm to rotate around the pivot point between the vertical plate and the active arm, so that the driven arm drives the guide part to complete the swinging action, so that the guide part can realize the function of tightening and resetting the material tray.

[0015] Furthermore, the guide part includes a swing rod, a driven arm is pivoted to the middle part of the swing rod, the mounting arm is screwed to the driven arm, the lower end of the swing rod is pivoted to one end of the fixed block, a strip plate is fixed to the upper end of the swing rod, and a guide wheel is rotatably connected to the strip plate.

[0016] Beneficial effect: The swing arm can swing around the pivot point between the fixed block and the swing arm under the drive of the transmission part, so that the guide wheel at the end of the swing arm can follow the swing, and then the guide wheel can approach and move away from the material tray, so that the guide wheel can press against and reset the material tray.

[0017] Furthermore, the guide portion further comprises a reinforcing rib plate, wherein the reinforcing rib plate is fixedly connected to one side of the swing rod, and an upper end of the reinforcing rib plate is fixedly connected to the strip plate.

[0018] Beneficial effect: The reinforcing rib plate can improve the strength of the swing rod and the strip plate, so that when the guide wheel pushes the material tray, the deformation of the strip plate and the swing rod is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
