Description

Technical Field

[0001] The utility model relates to the technical field of gas meter assembly equipment, in particular to a compact tooling tray assembly line. Background Art

[0002] At present, in the automatic assembly process of gas meters, the upper shell, lower shell and other appearance parts need to be transported by tooling pallet assembly line. By using tooling pallet assembly line, the workload of manual handling can be greatly reduced, the labor intensity of workers can be reduced, and the comfort of the working environment can be improved;

[0003] Pallet conveyors are usually composed of conveyor frames, pallets, drive devices, conveyor belts, etc. When the goods are placed on the pallet, the drive device drives the pallet to rotate or move through the transmission shaft, so that the goods move with the pallet and finally reach the destination.

[0004] In the current industry, pallet conveyors are mainly of two types: flat circulation and up-and-down circulation. The circular pallet conveyor occupies a very large area. The double-layer tooling pallet line needs to be equipped with elevators at both ends. The size of the elevators at both ends is wider than the size of the conveyor. When multiple lines are laid together, the spacing between the conveyors also needs to be widened. Small robots are difficult to reach, and the lower conveyor is also difficult to maintain. For this reason, we propose a compact tooling pallet assembly line. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a compact tooling pallet assembly line. The conveyor has the same length, the chain is half as much, and only one power source is used. The upper and lower handling equipment is embedded on the inner side of the conveyor, which does not increase the width of the conveyor, reduces the overall footprint of the compact tooling pallet assembly line, and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a compact tooling pallet assembly line, including a double-layer conveyor, an embedded upgrading mechanism and a frame;

[0007] Double-layer conveyor: It includes a power mechanism, a chain tensioning shaft and a double-layer double-speed chain. The chain tensioning shaft is rotatably connected to the left and right sides of the frame, and sprockets are arranged on the front and rear sides of the outer arc surface of the chain tensioning shaft. Four sprockets adjacent to each other in the horizontal direction are connected by a double-layer double-speed chain. The power mechanism is arranged on the right side of the front end of the frame, and the power mechanism is connected to the double-layer double-speed chains adjacent to each other in the horizontal direction.

[0008] Embedded upgrade mechanism: It is set on the right side inside the frame. For conveyors of the same length, the number of chains is reduced by half, and only one power source is used. The up and down handling equipment is embedded inside the conveyor, without increasing the width of the conveyor, reducing the overall floor area of the compact tooling pallet assembly line.

[0009] Furthermore, the power mechanism further includes a speed-regulating motor and a power shaft. The speed-regulating motor is set on the right side at the front end of the frame. The rear end of the output shaft of the speed-regulating motor is provided with a power shaft. Driving sprockets are arranged on both the front and rear sides of the outer arc surface of the power shaft. The driving sprockets are respectively in transmission connection with the double-layer double-speed chains adjacent horizontally. The input end of the speed-regulating motor is electrically connected to the output end of an external control device, and can drive the double-layer double-speed chains to rotate.

[0010] Furthermore, the embedded upgrade mechanism includes a large lifting cylinder. The large lifting cylinder is set on the right side inside the frame and can adjust the position of the lifting cylinder.

[0011] Furthermore, the embedded upgrade mechanism further includes a lifting cylinder. The lifting cylinder is set at the left end of the telescopic end of the large lifting cylinder and can drive the tooling pallet to move.

[0012] Furthermore, the embedded upgrade mechanism further includes a rotary cylinder. The rotary cylinder is set at the upper end of the telescopic end of the lifting cylinder and can drive the tooling pallet to rotate.

[0013] Furthermore, the embedded upgrade mechanism further includes a tooling pallet and a clamping cylinder. The clamping cylinder is set at the left end of the rotary cylinder. The tooling pallets are all on the left side of the clamping cylinder. The jaws of the clamping cylinder are all in contact with the outer surface of the upper tooling pallet and can clamp and fix the tooling pallet.

[0014] Furthermore, the embedded upgrade mechanism further includes a drag chain. The drag chain is set at the lower side of the left end of the lifting cylinder and can protect and guide components such as cables, air pipes, and hydraulic pipes, ensuring that these components can work stably and safely during the movement of the equipment.

[0016] 1. The output shaft of the speed-regulating motor drives the power shaft to rotate.

The chain tensioning shafts 12 are respectively rotatably connected to the left and right sides inside the frame 3. Sprockets are arranged on both the front and rear sides of the outer arc surface of the chain tensioning shaft 12. A double-layer double-speed chain 13 is used to drive and connect between every four horizontally adjacent sprockets. The power mechanism 11 is arranged on the right side at the front end of the frame 3, and the power mechanism 11 is respectively in driving connection with the horizontally adjacent double-layer double-speed chains 13. The power mechanism 11 further includes a speed-regulating motor 111 and a power shaft 112. The speed-regulating motor 111 is arranged on the right side at the front end of the frame 3. A power shaft 112 is arranged at the rear end of the output shaft of the speed-regulating motor 111. Driving sprockets are arranged on both the front and rear sides of the outer arc surface of the power shaft 112. The driving sprockets are respectively in driving connection with the horizontally adjacent double-layer double-speed chains 13. The input end of the speed-regulating motor 111 is electrically connected to the output end of an external control device. The output shaft of the speed-regulating motor 111 drives the power shaft 12 to rotate, and the power shaft 12 drives the double-layer double-speed chain 13 to rotate through the driving sprockets, thereby driving the tooling tray 21 to move. The upper and lower layers share a power source through the winding method of the double-speed chain, with lower hardware costs. For a conveyor of the same length, the number of chains is reduced by half, and maintenance is more economical;

[0028] Embedded upgrade mechanism 2: It is arranged on the right side inside the frame 3. The embedded upgrade mechanism 2 includes a large lifting cylinder 25, and the large lifting cylinder 25 is arranged on the right side inside the frame 3. The embedded upgrade mechanism 2 further includes a lifting cylinder 24, and the lifting cylinder 24 is arranged at the left end of the telescopic end of the large lifting cylinder 25. The embedded upgrade mechanism 2 further includes a rotary cylinder 23, and the rotary cylinder 23 is arranged at the upper end of the telescopic end of the lifting cylinder 24. The embedded upgrade mechanism 2 further includes a tooling tray 21 and a clamping cylinder 22, and the clamping cylinder 22 is arranged at the left end of the rotary cylinder 23.

[0029] The working principle of a compact tooling pallet assembly line provided by the present utility model is as follows: When the compact tooling pallet assembly line is working, through the regulation of an external driving device, the speed-regulating motor 111 starts to operate. The output shaft of the speed-regulating motor 111 drives the power shaft 12 to rotate. The power shaft 12 drives the double-layer double-speed chain 13 to rotate through a driving sprocket, thereby driving the tooling pallet 21 to move. When the upper tooling pallet 21 moves to the right side of the frame 3, the external solenoid valve controls the jaws of the clamping cylinder 22 to clamp the tooling pallet 21. Then, the external solenoid valve controls the lifting cylinder 24 to rise, so that the tooling pallet 21 is separated from the double-layer double-speed chain. At this time, the external solenoid valve controls the rotating cylinder 23 to rotate the tooling pallet 21 by 90 degrees. After that, the external solenoid valve controls the large lifting cylinder 25 to descend, and then the external solenoid valve controls the rotating cylinder 23 to rotate the tooling pallet 21 by 90 degrees to return to the original position. At this time, the external solenoid valve controls the lifting cylinder 24 to descend. Finally, the external solenoid valve controls the jaws of the clamping cylinder 22 to open, so that the tooling pallet 21 can flow into the lower-layer return line.

[0030] It should be noted that the speed-regulating motor 111 disclosed in the above embodiments can be selected as FTY18500-6, and a control button corresponding to the speed-regulating motor 111 for controlling its switch is provided on the external control device.
