The invention relates to a workshop conveyor system; in particular to a workshop conveyor system of an automatic welding platform, which is used for conveying workpieces among different stations in an automatic welding production line.

Background

The automatic/intelligent welding system is characterized in that welding work which needs high manual participation originally is executed through automatic means such as a mechanical arm and the like by the aid of intelligent equipment such as a computer, the automatic welding system is usually applied along with a production line, transfer of workpieces on the welding production line is an important design link, and the processing efficiency and quality of the whole production line can be fully guaranteed through efficient and stable workpiece transfer. The processing platform in the assembly line is a platform used for bearing and transferring workpieces in the assembly line, the product pieces are placed on the platform to be welded and the like, the processed workpieces can move between different stations on the assembly line, and the movement can be realized through various driving mechanisms on the surface of the platform, for example, rollers are arranged on the surface of the platform.

Chinese patent with patent publication No. CN208880644U discloses a platform for processing large-scale plates of automobile, which comprises a processing table, a control center, the first hydraulic pressure lifts up the mechanism, the second hydraulic pressure lifts up the mechanism, the third hydraulic pressure lifts up the mechanism, the fourth hydraulic pressure lifts up the mechanism, the first lateral pressure mechanism, the second lateral pressure mechanism, the processing table middle zone evenly is provided with four through-holes, the both sides of the mesa of processing table all are provided with the spout, the control center all lifts up the mechanism with the first hydraulic pressure, the second hydraulic pressure lifts up the mechanism, the third hydraulic pressure lifts up the mechanism, the fourth hydraulic pressure lifts up mechanism electric connection, the control center and the first lateral pressure mechanism, the equal electric connection of second lateral pressure mechanism, the first lateral pressure mechanism, the second lateral pressure mechanism all with spout sliding connection. The hydraulic lifting device can lift the processed large plate; through the setting of cylinder, can be fine promote panel.

Because the hydraulic lifting device on the processing platform needs to penetrate through the platform after being vertically lifted, a through hole for the hydraulic lifting device to pass through needs to be reserved on the platform, and in order to meet the requirement that a roller needs a certain volume, the area of the through hole is not small. Meanwhile, when the platform needs personnel to step into construction operations such as maintenance and the like, after the hydraulic lifting device is vertically lowered, the through hole forms potential safety hazards, and the personnel can step into the through hole if the personnel moves carelessly on the platform, so that accidental injuries are caused to the personnel.

Disclosure of Invention

The invention aims to provide an automatic welding processing conveying platform, so as to avoid the problem that a larger installation space is required to be arranged at the lower part of a processing platform.

Automatic welding processing conveying platform in this scheme includes the platform and locates cylinder, driving medium and actuating mechanism among the platform, and actuating mechanism orders about the cylinder through the driving medium and goes up and down, and the driving medium rotates to be connected in the platform, and actuating mechanism establishes in the platform according to its length direction level.

The platform, i.e., the platform body, is primarily characterized by the portion of the processing platform used to drive the workpiece. The length direction of the shape-variable driving mechanism is the longest direction in each shape, for example, when the driving mechanism is a long-strip-shaped air cylinder, the driving mechanism can be horizontally installed in the platform, the length direction of the air cylinder is preferably consistent with the longer direction of the platform, and the piston rod horizontally reciprocates, so that the requirement on the height of an installation space can be reduced.

In this scheme, when needs the cylinder to go up and down, actuating mechanism orders about the driving medium and rotates, further orders about the cylinder and takes place altitude variation. The rotation of transmission parts in the whole process can smoothly convert the driving forces in different directions into the height change of the roller.

Further, the hinged center of the transmission member and the platform is positioned above the geometric center of the transmission member.

The hinge center refers to the geometric center of the rotating circumference of the transmission piece, and the geometric center of the transmission piece refers to the geometric center of the transmission piece in a vertical state. When the stress point is at the lower end of the transmission part and drives the transmission part to rotate, the vibration is generated due to the inevitable fit clearance at the hinged part, the shorter the distance from the vibration part to the end part (the end connected with the roller) is, and the weaker the vibration of the end part is under the amplification effect of the lever. The processing work on the platform is more stable.

Further, the transmission part comprises a force arm and a movable arm which are integrally in a 7 shape, the driving mechanism is a telescopic driving mechanism, the force arm is connected with the driving mechanism, and the movable arm is connected with the roller.

The telescopic driving mechanism comprises a driving device which outputs power through length change, such as an air cylinder, an oil cylinder, a telescopic motor and the like.

The force arm and the movable arm form a certain angle with each other and integrally form a 7 shape, the force arm can swing back and forth in the direction of the vertical line, and the movable arm swings up and down in the horizontal line. The shape can more effectively convert the horizontal power into the height change of the roller; although the roller does not vertically lift, the displacement of the roller in the horizontal direction is small in the lifting process, and a large through hole is not required to be formed in the platform surface.

Further, the transmission member includes a pair of arms and a boom, and the drum is disposed between the pair of booms. Such a construction ensures a better coupling of the transmission member to the supporting roller, since the roller needs to have a certain length in order to give a more stable support to the work piece being machined.

Furthermore, the movable arm is provided with upward paired square connecting grooves, the rotating shaft is clamped in the connecting grooves through square heads at two ends, and the roller is rotationally connected to the rotating shaft. The roller and the rotating shaft can be quickly installed on the movable arm through the connecting groove. Because the roller is always acted by downward force and the opening of the connecting groove faces upward in the working process, the roller can normally work without overlarge clamping force between the connecting groove and the rotating shaft, and is more convenient and labor-saving in disassembly and assembly.

Further, the roller at the lower limit is flush with the upper surface of the platform. When the cylinder fell to the end promptly, the last edge and the platform upper surface parallel and level of cylinder basically, even personnel stepped on the through-hole, the cylinder also can support personnel's foot, avoided falling the accident.

Furthermore, a sealing plate is arranged at the position, corresponding to the through hole, of the upper portion of the transmission part, and the upper limit of the sealing plate is flush with the upper surface of the platform.

The linkage seat side plate can be selectively installed on the linkage seat according to the lifting height, and after a sealing plate is added, the gap between the linkage seat side plate and a platform hole is reduced, and the safety is improved. The sealing plate can not be too protruded to influence the work of the surface of the platform when moving to the upper limit, and the upper surface of the sealing plate has little influence even if being slightly lower or higher than the upper surface of the platform.

Furthermore, the platform is provided with two or more grouped transmission parts and rollers, and the driving mechanism is connected with the transmission parts at the same time. A small number of driving mechanisms can be used for driving the plurality of rollers to lift simultaneously, so that a power source is saved, and the synchronism of the lifting of the rollers is improved.

Further, the driving mechanism is connected with the transmission piece through the long cross rod capable of horizontally reciprocating. The driving mechanism drives the long cross rod to do horizontal reciprocating motion, the long cross rod drives the rollers to lift through the transmission pieces, and synchronous lifting of a plurality of long-distance rollers can be achieved.
