[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1-Figure 4 ,in, Figure 1 This is a schematic diagram of the overall structure of a fixed tray for a heat treatment furnace provided by the utility model; Figure 2 for Figure 1 The overall structural diagram of the fixed assembly shown; Figure 3 for Figure 2 The schematic diagram of the split structure of the fixed component shown; Figure 4 for Figure 2 The overall structural schematic diagram of the chain plate is shown.

[0024] In the specific implementation process, Figure 1-Figure 4 As shown, a fixed tray for a heat treatment furnace comprises a carrier plate 1 placed in the heat treatment furnace, and fixing components are respectively arranged on both sides of the top of the carrier plate 1, and the two fixing components are symmetrically arranged;

[0025] The fixing assembly includes a chain plate, two threaded columns 2 and a driving mechanism. A fixing block 3 is provided on the top of the load-bearing plate 1. The driving mechanism is located in the fixing block 3. One end of the two threaded columns 2 passes through one side of the driving mechanism. One end of the two threaded columns 2 is provided with a connecting plate 4 respectively. One side of the two connecting plates 4 is rotatably connected to one end of the two threaded columns 2 respectively. A hinge plate 5 is fixed to one end of the two connecting plates 4 away from the threaded column 2. Both ends of one side of the chain plate are fixed with hinge seats 6 respectively. Limiting columns 7 are provided in the two hinge seats 6 respectively. One end of the two limiting columns 7 passes through the top of the two hinge plates 5 respectively. Both ends of the two limiting columns 7 are fixedly connected to both sides of the inner walls of the two hinge seats 6 respectively. The chain plate includes multiple bonding plates 8. Multiple bonding plates 8 are arranged in an arc shape, and two adjacent bonding plates 8 are connected by hinges 9. By rotating the threaded column 2, the rotation of the threaded column 2 will push the connecting plate 4 to approach the workpiece, and the connecting plate 4 pushes the multiple bonding plates 8 connected end to end to contact the workpiece surface through the hinge plate 5 and the hinge seat 6. Since the multiple bonding plates 8 are connected by hinges 9, the multiple bonding plates 8 can change the curvature formed between the multiple bonding plates 8 according to the curvature of the workpiece surface. In the bonding process, the distance between the two bonding plates 8 at the two ends will decrease, so it is necessary to drive the two threaded columns 2 to be relatively close to each other to avoid the bonding plates 8 from getting stuck;

[0026] The driving mechanism includes a rotating rod 10 and two sliders 11. A through groove is provided on one side of the fixed block 3. A handle is fixed on one end of the rotating rod 10. The end of the rotating rod 10 away from the handle movably penetrates one end of the fixed block 3 and is rotatably connected to one side of the inner wall of the through groove. The surface of the rotating rod 10 is provided with two threads in opposite directions. The two sliders 11 are respectively threadedly sleeved on the two ends of the surface of the rotating rod 10. The two threaded columns 2 respectively penetrate one side of the two sliders 11. The surfaces of the two threaded columns 2 are respectively threadedly connected with the internal threads of the two sliders 11, so that the rotating rod 10 rotates. The rotating rod 10 drives the two sliders 11 to be relatively close to each other through the thread, so that the two threaded columns 2 are relatively close to each other, which can prevent the bonding plate 8 from getting stuck.

[0027] Limit blocks 12 are fixedly provided at the top and bottom of the slider 11, and limit grooves 13 are provided at the top and bottom of the inner wall of the through groove, respectively. The two limit blocks 12 are respectively located in the limit grooves 13, and the limit blocks 12 can slide in the limit grooves 13 to limit the slider 11 and prevent the slider 11 from rotating with the rotating rod 10;

[0028] A guide rod 14 is fixedly provided at one end of the connecting plate 4 close to the threaded column 2, and an end of the guide rod 14 away from the connecting plate 4 movably penetrates one side of the slider 11. The guide rod 14 can slide in the slider 11 to limit the connecting plate 4 to prevent the threaded column 2 from driving the connecting plate 4 to rotate;

[0029] The handle includes a fixed plate 15 and a push column 16. One side of the fixed plate 15 is fixedly connected to one end of the rotating rod 10. One end of the push column 16 is rotatably connected to the edge of the fixed plate 15 away from the rotating rod 10. By pulling the push column 16, the fixed plate 15 is driven to rotate, thereby rotating the rotating rod 10.

[0030] A fixing column 17 is fixedly provided at one end of the threaded column 2 away from the connecting plate 4. A through hole is opened on the side surface of the fixing column 17, and a lever column 18 is provided in the through hole. The lever column 18 can slide in the through hole. By twisting one end of the lever column 18, the lever column 18 drives the fixing column 17 to rotate, and the fixing column 17 drives the threaded column 2 to rotate.

[0031] The working principle provided by the utility model is as follows: a columnar workpiece is placed on the top of the supporting plate 1, and by twisting one end of the pulling column 18, the pulling column 18 drives the fixed column 17 to rotate, and the fixed column 17 drives the threaded column 2 to rotate. Due to the threaded connection between the threaded column 2 and the slider 11, the rotation of the threaded column 2 will push the connecting plate 4 to approach the workpiece, and the connecting plate 4 pushes multiple bonding plates 8 connected end to end to contact the workpiece surface through the hinge plate 5 and the hinge seat 6. Since multiple bonding plates 8 are connected by hinges 9, multiple bonding plates 8 can change the curvature formed between multiple bonding plates 8 according to the curvature of the workpiece surface. During the bonding process, the distance between the two bonding plates 8 at the two ends will be reduced. Therefore, by pulling the pushing column 16, the fixed plate 15 is driven to rotate, thereby causing the rotating rod 10 to rotate, and the rotating rod 10 drives the two sliders 11 to be relatively close through the thread, thereby causing the two threaded columns 2 to be relatively close, thereby preventing the bonding plates 8 from getting stuck.
