Technical Field

[0001] This utility model belongs to the field of metal heat treatment technology, and more specifically, it relates to a metal heat treatment clamp. Background Technology

[0002] Metal heat treatment is a key process that alters the microstructure and properties of metallic materials by controlling the heating, holding, and cooling processes. It mainly includes annealing, normalizing, quenching, tempering, and chemical heat treatment. Its core purpose is to improve the material's hardness, strength, wear resistance, or toughness, and to eliminate internal stress and processing defects. Modern technologies such as vacuum heat treatment and induction heating have further improved process precision and environmental friendliness, becoming an indispensable industrial foundation technology in high-precision fields such as aerospace and automotive manufacturing. During heat treatment, tooling fixtures are required to hold the parts.

[0003] Based on the above, the inventors have discovered the following problem: When columnar parts are subjected to metal heat treatment, they are usually stacked on a tooling rack, which makes them prone to rolling off, resulting in low safety.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a metal heat treatment clamp to achieve a more practical purpose. Utility Model Content

The placement grooves and through holes are matched in size. Both the placement tray and the support tray have connecting holes on their surfaces, and a connecting rod is installed in the connecting hole. The bottom of the placement tray has a first groove, and the bottom of the connecting rod has a first support block installed in the first groove. The support tray is connected to the connecting rod through a mechanism for moving the support tray.

[0008] Furthermore, the mechanism of the movable support plate includes a sleeve fitted on the connecting rod, a second support block installed on the surface of the sleeve, a second groove opened at the bottom of the support plate, the second support block located in the second groove, a plurality of through holes opened on the connecting rod and a threaded hole opened on the sleeve, and a fixing bolt, the fixing bolt passing through one side of the sleeve and the through holes and turning into the threaded hole.

[0009] Furthermore, limit blocks are installed on the surfaces of both the first and second support blocks, and limit grooves are formed in the connecting holes of the placement plate and the support plate. The limit grooves and placement grooves are matched. When the limit grooves and limit blocks on the placement plate and the support plate are aligned, the through holes and placement grooves are aligned.

[0010] Furthermore, the surfaces of the placement plate and the support plate are provided with multiple honeycomb holes.

[0011] Furthermore, a clamping groove is formed on the surface of the connecting rod near the top.

[0012] Furthermore, when the first groove is located inside the first support block, the bottom of the first support block is flush with the bottom of the placement plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model utilizes a placement plate, placement groove, support plate, through hole, connecting hole, connecting rod, first groove, first support block, mechanism for moving support plate, limiting block, and limiting groove in cooperation. In use, first, the connecting rod is placed on the ground. Then, the limiting groove on the placement plate is aligned with the limiting block on the first support block for installation, so that the first groove is engaged in the first support block. The height of the sleeve can then be adjusted according to the height of the parts requiring heat treatment. To adjust, simply remove the fixing bolt, move the sleeve to the appropriate height, and then insert the fixing bolt to secure the sleeve. Next, the upper limiting groove on the support plate is aligned with the limiting block on the second support block for installation, so that the second groove is engaged in the second support block. At this point, the through hole and placement groove are aligned. The parts requiring heat treatment are then placed through the through hole into the placement groove.
