Description

Technical Field

[0001] The utility model belongs to the field of heat treatment devices, and in particular relates to a workpiece heat treatment device. Background Art

[0002] During the heat treatment process of semi-axle workpieces, a fixture is needed to store the semi-axle workpieces. Usually, a hanging cage-type fixture is used to store semi-axle workpieces. This type of fixture has four columns, and adjacent columns are connected by cross bars. By placing the two ends of the workpiece on the cross bars, the workpiece is supported, but the workpiece is prone to slide on the cross bars.

[0003] A Chinese patent with publication number CN220683198U discloses a workpiece heat treatment device, including two cross bars and a support assembly, the cross bar having multiple grooves, the support assembly including two support frames, two sliding bars, a hollow column and a driving unit; the two support frames are fixedly connected to the two cross bars, the two sliding bars are fixedly connected to the two support frames, the hollow column is slidably connected to the two sliding bars, and the driving unit is arranged on the hollow column; the driving unit drives the two sliding bars to slide along the hollow column, so that the two sliding bars move away from each other, and the sliding bar drives the support frame and the cross bar to move, so that the spacing between the two cross bars changes to adapt to semi-axial workpieces of different lengths, and semi-axial workpieces of different lengths can be stored. However, the workpiece heat treatment device in this application, after adjusting the spacing between the two cross bars, places the workpiece on the cross bar, and then needs to manually slide the pressure rod, and then drive it to be fixed by bolts, and the efficiency of workpiece placement and positioning is slow.

[0004] In view of this, the present utility model is proposed. Utility Model Content
