Description

Technical Field

[0001] The utility model belongs to the technical field of automatic assembly, and in particular relates to a connecting rod body and connecting rod cover disassembly device. Background Art

[0002] Each engine requires 4 connecting rods. Before assembling the connecting rods, the connecting rod bolts need to be loosened, the connecting rod body and connecting rod cover need to be disassembled, and the tiles need to be pressed separately. The traditional method is that manual worker 1 places the connecting rods on the line body tray one by one, and scans the connecting rod QR code with a handheld barcode scanner. Four connecting rods of the same weight are grouped together. Manual worker 2 uses four markers to paint green, white, blue and yellow colors on the joints of the connecting rod body and the connecting rod cover to ensure that the disassembled connecting rod body and connecting rod cover are installed in pairs, and the fixed colors are installed in the fixed position of the engine. Manual worker 3 places the connecting rod on the bolt disassembly equipment, and manually operates the equipment to loosen the connecting rod bolts. Only two connecting rods can be disassembled at the same time. Manual worker 4 picks up the two sets of disassembled connecting rod bodies and connecting rod covers to the pressing equipment, and then manually places the four tiles to the pressing position, and operates the equipment to press the tiles into the connecting rod body and connecting rod cover respectively.

[0003] Automated assembly is not achieved in the existing technology, and multiple process links are completed manually, which takes up and wastes manpower, and the production rhythm is inconsistent, the production capacity is unstable, and the operation efficiency is low.

[0004] The connecting rod body and the connecting rod cover are connected together by bolts. There will be metal cutting chips or other impurities on the contact surface of the two. If the impurities are not cleaned in time after the connecting rod body and the connecting rod cover are disassembled, it will affect the subsequent tile pressing process. If the tile is scratched or worn, it will seriously affect the assembly accuracy. Utility Model Content

DETAILED DESCRIPTION

[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

The end of the clamping block 511 has a clamping opening 5111 for clamping the end of the connecting rod body 81 .

[0025] A connecting rod spreading mechanism is also provided under the connecting rod placement plate 52, and the connecting rod spreading mechanism includes a fixed block 56 and a movable block 57 opposite to the fixed block 56, and the fixed block 56 and the movable block 57 extend upward from the bottom of the connecting rod placement plate 52; when the connecting rod is placed on the connecting rod placement plate 52, the fixed block 56 and the movable block 57 fit together, and the fixed block 56 and the movable block 57 are just stuck in the mounting hole in the middle of the connecting rod 8.
