Description

Technical Field

[0001] The invention relates to the technical field of chain track segment processing, in particular to a loading and unloading device for processing crawler chain track segments. Background Art

[0002] The track link is the connecting part of the engineering machinery crawler. The production process of the track link is: cutting → die forging → punching and trimming → heat treatment → milling of both sides → boring → drilling of bolt holes → pushing nut surface. The track link is forged on the processing line, and the track link after fine processing and grinding is transported to the MT inspection area through the conveyor track for MT flaw detection after forging.

[0003] For example, a conveying device for a chain track segment with publication number CN117401402B comprises a conveying track, an outer frame is fixedly connected to the outer side of the conveying track, a chain track segment bearing module is snap-connected to the conveying track, and the chain track segment bearing module comprises a conveying bottom plate, a lower profiling bearing seat and a closed bottom shell, the lower profiling bearing seat and the closed bottom shell are both fixedly connected to the top of the conveying bottom plate, the lower profiling bearing seat of the matching chain track segment is provided for the chain track segment to be placed, the protruding end cover shell, the arc-shaped protruding part cover shell, the flat end cover shell and the side recessed part cover shell move downward to press the chain track segment from above, and After the lower contoured bearing seat is clamped, the chain track segment is completely in a closed space. The spraying member disperses and releases the magnetic powder liquid directly to different areas of the closed isolation space and the four holes of the chain track segment, which is beneficial to control the retention amount and contact time of the magnetic powder liquid on the outside of the finished chain track segment. However, the device fixes the chain track segment through the lower contoured bearing seat, which is only convenient for the use of this type of chain track segment. When the size of the chain track segment is different, for example, when the internal opening is small, it is not convenient to firmly position the chain track segment, which makes the device limited, with poor flexibility in use and a small scope of application.

[0057] Working principle: When using the device, first, Figure 1-10 As shown, the loading and unloading operations of the chain track segment are realized by two manipulator devices 4. The manipulator device 4 places the chain track segment on the placement plate 52. After positioning and placing it through the positioning rod 53 cooperating with the hole on the chain track segment, the placement plate 52 is pressed down by the gravity of the chain track segment. The placement plate 52 compresses the spring 1 57 and moves downward. The guide rod 56 is used to guide the placement plate 52. The placement plate 52 drives the rack 58 to move downward.

The limiting block 520 compresses the spring three 521 to facilitate the limiting of the pushing block 519. The pushing block 519 moves to squeeze the inclined surface of the inclined block 523, and the inclined block 523 drives the second clamping plate 55 to slide on the inner rod 522, so that the two second clamping plates 55 clamp the front and rear sides of the chain track section.

[0059] After the chain track segment is placed on the placement plate 52 and positioned, the conveyor belt 3 drives the placement seat 51 to move, and the conveyor belt 3 moves intermittently until the placement seat 51 moves to the bottom of the material box 61, the electric push rod 62 drives the cross plate 64 to descend, and the cross plate 64 drives the positioning frame 65 to descend, so that the positioning frame 65 fits the outer side of the placement seat 51. At this time, the pressure pump inside the material box 61 pumps the magnetic powder liquid into the placement seat 51 through the connecting pipe 63, so that the magnetic powder liquid can cover the surface and holes of the chain track segment, thereby improving the coating effect. Then, the electric push rod 62 drives the cross plate 64 to rise, and the conveyor belt 3 continues to drive the placement seat 51 to move. When passing through the detection device 7, the detection device 7 detects the chain track segment inside the placement seat 51.
