Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicle production, and in particular to a workpiece limiting device and a limiting method for a rail vehicle intelligent production line. Background Art

[0002] With the rapid development of social economy, urban traffic pressure is increasing year by year. In order to alleviate urban traffic pressure, rail vehicles are put into mass production and used in the transportation process. Whether it is transporting passengers or cargo, rail vehicles play an irreplaceable role. Therefore, the application demand of rail vehicles is increasing year by year. For the production of rail vehicles, the assembly line is used to assemble the body of the vehicle. Then, the parts required for assembly need to be transported to the assembly table by conveying equipment. During the transportation process, due to the different shapes and structures of the parts, it is easy to shake due to unstable center of gravity during the transportation process, resulting in the transmission of the parts.

[0003] Falling off the equipment causes irreversible deformation of the parts after they fall, requiring the parts to be returned to the factory, seriously affecting the efficient assembly of the entire car body.

[0004] In order to solve the above technical problems, a workpiece limiting device and a limiting method for a rail vehicle intelligent production line are disclosed in the existing Chinese patent publication number CN115783634A. The device uses a conveying component composed of several support plates to convey rail vehicle parts to an assembly table for assembly. During the conveying process, the outer

[0005] To limit parts with different shapes and structures, it is necessary to adjust the clamping space size of the two clamping plates of the limiter, so as to meet the transmission limit requirements of parts with different shapes and structures, and avoid them from falling from the conveying equipment due to shaking due to unstable center of gravity during transmission, resulting in irreversible deformation of parts after falling. Finally, the parts need to be returned to the factory, which seriously affects the efficient assembly of the entire car body.

[0027] Furthermore, it is convenient to move the workpiece.

[0028] The present invention also proposes a limiting method for a workpiece limiting device of a rail vehicle intelligent production line, comprising the following steps:

[0029] S1. When in use, place the workpiece into the feeding plate and move the workpiece toward the conveyor belt;

[0030] S2, the staff controls the electric telescopic rod to make the connecting card drive the second linkage belt to move, which can make the two second linkage wheel members and one of the second gear members rotate. When the second linkage wheel member rotates, the synchronous shaft member can rotate, which makes the synchronous rod member and the two rotating rod members cooperate to drive the supporting shaft member to rotate;

[0031] S3. When the supporting shaft rotates, the first gear member fixed thereto drives another first gear member to move the two third linkage wheel members and the third linkage belt member, which can drive the circular shaft member and the supporting shaft member to operate in the opposite direction, so as to drive the first swing member to swing through the contact plate member. Through the movement of the two first swing members, the distance between the two first swing members can be retained to adapt to the distance of the workpiece to be moved out;

[0032] S4. When the workpiece and the first swing arm are in conflict, the first swing arm can drive the bearing block to move along the supporting rod through the push rod, and can squeeze the resistance spring, leaving a certain deflection distance for the first swing arm, so as to better adapt to the sequential movement of the workpieces;

[0033] S5. The staff can control the operation of the hydraulic cylinder assembly, so that the contact wheel part can contact the side wall in the opening to rotate the square frame part. When the square frame part rotates, the vertical shaft part can be rotated, and the reverse gear part on the vertical shaft part can be operated. Through the cooperation of the two reverse gear parts, one of the first linkage wheel parts can be rotated, and the rotating shaft part and the vertical shaft part can be rotated in the opposite direction through the first linkage belt part. The intuitive display is that when the cross bar part away from the feeding plate part is parallel to the conveyor belt, that is, the railing part away from the feeding plate part is located at the upper end of the conveyor belt, the railing part close to the feeding plate part is tilted, which can make the workpiece move and contact the railing part away from the feeding plate part. When the railing part close to the feeding plate part is vertically set, it can block the movement of the workpiece. At this time, the railing part away from the feeding plate part is tilted, which can make the workpiece that conflicts with it move, so as to realize sequential single conveying;

[0034] S6. When the second swing rod swings, it will drive the splint conveying assembly to move. At the same time, the sliding rod, sleeve and slider can ensure the smooth movement of the splint conveying assembly, which is convenient for effectively limiting the position of the workpiece and ensuring that the workpiece can be transported stably.

[0035] The beneficial effects of the present invention are:

[0036] 1. The present application enables the second linkage belt to operate through the action of the electric telescopic rod and the connecting clamp, and enables the vertical shaft and the synchronous shaft to rotate in opposite directions through the action of the two second gear members, and can adjust the distance between the two second swing rod members to adapt to the specifications of a single workpiece;

[0037] 2. When the synchronous shaft rotates, the support shaft can be rotated by the cooperation between the synchronous rod and the two rotating rods, and the circular shaft and the support shaft can be rotated in the opposite direction by the two first gears, the third linkage belt and the two third linkage wheels, so that the contact plate and the second swing rod can operate synchronously;

[0038] 3. At the same time, the push rod can be rotated by the action of the resistance spring and the bearing block to make the first swing rod rotate, so as to adapt to the deviation of the corresponding parts. In actual use, a limiting component can be installed on the side where the resistance plate and the first swing rod are hinged, so as to limit the deflection angle of the first swing rod and the movement of the workpiece, so as to ensure the stable transportation of the workpiece.

[0039] 4. The hydraulic cylinder assembly can drive the contact wheel to contact the side wall in the opening to deflect the frame. The deflection of the frame can drive the vertical shaft to rotate, and the two reverse gears, the first linkage belt and the two first linkage wheels make the rotating shaft and the vertical shaft rotate in opposite directions. The intuitive display is that when the crossbar far away from the feeding plate is parallel to the conveyor belt, that is, the railing far away from the feeding plate is located at the upper end of the conveyor belt, the railing close to the feeding plate is tilted, which can make the workpiece move and contact the railing far away from the feeding plate. When the railing close to the feeding plate is vertically set, it can block the movement of the workpiece. At this time, the railing far away from the feeding plate is tilted, which can make the workpiece in conflict with it move, so as to realize sequential single conveying.

[0040] 5. When the components are in operation, the corresponding wheels and bags used for transmission are arranged into a toothed structure to ensure the stability of transmission;

[0041] 6. When the second rocker member swings, the splint conveying assembly moves, and the movement of the splint conveying assembly drives the sliding bar member to move. The sliding bar member ensures that the splint conveying assembly can move smoothly through the action of the sleeve member, the slider member and the slide rail member, and can effectively limit the distance between the two splint conveying assemblies, and can effectively limit the workpiece to the middle of the conveyor belt to achieve stable movement.
