Description

Technical Field

[0001] The utility model relates to the technical field of fixing jigs, in particular to a lifting jig for an iron bucket production line. Background Technique

[0002] An iron bucket is a common container in life, which has the advantages of high strength and good sealing performance, and can be used as the basic packaging for liquid products such as paint, coating, and engine oil. The production process of an iron sheet bucket generally includes barrel body cutting, lid stamping, composite ring stamping, curling, spot welding, seam welding, ring ribbing, flanging, necking, pipe rolling, edge rolling, ladder hand spotting, hoop body cutting, hoop ear spot welding, handle spot welding, fitting assembly, closure spot welding, and final assembly inspection.

[0003] In the production of iron buckets on the production line, the processing stations are generally arranged above the production line, and the iron bucket workpieces are pushed into the stations for processing through a lifter. Therefore, the lifter requires a jig to fix the iron bucket workpieces to prevent the iron bucket from tilting and falling during lifting. However, the existing jigs generally use corresponding pneumatic jigs on both sides of the output end of the lifter to clamp and fix the iron bucket workpieces without affecting the entry and exit of the production line. Although it can meet the fixing requirements of the workpieces, due to the need to set corresponding cylinders, pneumatic pipelines, and control valves, it increases the maintenance difficulty of the equipment, and the lifting plate of the lifter needs to be widened, which is prone to interference with the iron bucket conveying mechanisms on both sides, and there is room for further improvement. Content of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a lifting jig for an iron bucket production line, which solves the above problems.

[0005] To achieve the above purpose, a lifting jig for an iron bucket production line is provided, which includes a lifting base and a lifter. A lifter is arranged at the center of the lifting base. A lifting column is arranged at the upper output end of the lifter. The top of the lifting column is fixedly connected with a lifting plate. Clamping grooves are respectively opened in the middle of both ends of the lifting plate. Fixed shaft seats are fixedly connected to the bottom of both sides of the lifting plate at one end of the clamping groove close to the lifting column. Two rotating jigs are rotatably connected in the two clamping grooves through the fixed shaft seats. The two rotating jigs are symmetrically arranged. Rotating shaft sleeves are respectively arranged on one side of the middle parts of the rotating jigs close to the fixed shaft seats. Spring connecting rods are fixedly connected above the rotating shaft sleeves of the rotating jigs. Clamping springs are respectively arranged on both sides below the lifting plate. Roller grooves are respectively opened at the bottoms of the two rotating jigs. Guide rollers are rotatably connected in the two roller grooves. Arc-shaped guide platforms are fixedly connected to the positions corresponding to the two rotating jigs on both sides above the lifting base.

[0006] Arc-shaped clamping blocks are provided on the inner sides of the tops of the two rotating jigs, and bottom hoop card slots are formed on the inner sides of the tops of the two rotating jigs below the arc-shaped clamping blocks.

[0007] According to the lifting jig for an iron barrel production line described above, fixed shafts are fixedly connected inside the two fixed shaft seats, and the rotating shaft sleeves of the two rotating jigs are respectively rotatably sleeved on the fixed shafts of the corresponding fixed shaft seats.

[0008] According to the lifting jig for an iron barrel production line described above, both ends of the two clamping springs are respectively fixedly connected to both ends of the corresponding spring connecting rods.

[0009] According to the lifting jig for an iron barrel production line described above, the two arc-shaped guide platforms are symmetrically arranged and arc-shaped surfaces are formed on the sides close to the lifter, and the bottoms of the two arc-shaped surfaces are tangent to the top surfaces of the arc-shaped guide platforms.

[0011] According to the lifting jig for an iron barrel production line described above, the maximum rotation trajectory ranges of the two rotating jigs are both located inside the corresponding jig slots.

[0012] The above solution has at least one of the following beneficial effects:

[0013] 1. By arranging rotating jigs below the two ends of the lifting plate of the present utility model, the clamping movement trajectory of the rotating jigs can be arc-shaped. When the lifting plate presses down and resets, in cooperation with the arc-shaped guide platform and the guide rollers, the fixture body can completely sink below the working surface of the lifting plate, avoiding interference with the conveying of workpieces. When the lifting plate rises, the rotating jigs can be rotated inward by stretching the clamping springs on both sides to clamp the workpieces. Thus, the clamping action is completed by the lifting action of the lifting plate. The structure is simple, the maintenance difficulty is low, and the practicability of the device is enhanced.

[0014] 2. By providing an arc-shaped clamping block and a bottom hoop card slot on the rotating jig of the present utility model, when the arc-shaped clamping block clamps the barrel body, the outer edge of the bottom hoop of the iron barrel can be clamped by using the bottom hoop card slot. And due to the rotational movement of the rotating jig itself, the arc-shaped clamping block can cut in from above the outer edge of the bottom hoop, avoiding the situation of hitting the outer edge of the bottom hoop and causing unstable clamping, greatly improving the clamping stability and enhancing the practicability of the device.
