The mechanical, parts and equipment in the device adopt conventional types in the existing technology, and the circuit connection adopts conventional connection mode in the existing technology, which will not be described in detail here.

[0026] Embodiment 2

[0027] The scheme in embodiment 1 will be further introduced in combination with specific working mode, which is described in detail as follows:

[0028] As Figures 1 to 3As shown, the displacement mechanism comprises a motor 11 and a lead screw 7, the lead screw 7 is rotatably arranged on the lifting plate 4, the motor 11 is installed on the side of the lifting plate 4, and the output end of the motor 11 is connected with one end of the lead screw 7, the moving plate 13 is threadedly sleeved on the lead screw 7, and the bottom end of the moving plate 13 is slidably arranged on the lifting plate 4, the moving plate 13 is rotatably sleeved on the surface of the fixed shaft 9, and the bottom end of the L-shaped fork plate 3 and the moving plate 13 are provided with a positioning mechanism, through the positioning mechanism, the L-shaped fork plate 3 can be prevented from continuing to swing after being swung to 90° with the fixed shaft 9, so that the L-shaped fork plate 3 can only swing 90° to both sides at the middle of the lifting plate 4, through the arrangement of the above structure, the rotation of the motor 11 can drive the lead screw 7 to rotate, and then the moving plate 13 drives the fixed shaft 9 to move, so as to control the L-shaped fork plate 3 to move to the feeding mechanism, take down the workpiece on the feeding mechanism, and then reverse the motor 11, that is, control the L-shaped fork plate 3 to swing the workpiece to the middle of the lifting plate 4, for subsequent putting into the heat treatment equipment.

[0029] As shown in Figure 3 , Figure 4 and Figure 7 , the transmission mechanism comprises a toothed plate 16, the toothed plate 16 is fixedly connected with the lifting plate 4, the bottom end of the fixed shaft 9 is fixedly connected with a gear 18, and the gear 18 is engaged with the toothed plate 16, through the above structure, when the moving plate 13 drives the fixed shaft 9 to move on the lifting plate 4, the gear 18 will rotate on the toothed plate 16, and then the fixed shaft 9 drives the L-shaped fork plate 3 to rotate and move, until the gear 18 moves away from the toothed plate 16, at this time, the L-shaped fork plate 3 will swing to 90°, so as to take down the workpiece of the feeding mechanism by the L-shaped fork plate 3, and after the moving plate 13 continuously drives the fixed shaft 9 to move, the L-shaped fork plate 3 and the fixed shaft 9 will move smoothly on the lifting plate 4, and will not swing.

[0030] As shown in Figure 1 and Figure 5As shown, the feeding mechanism includes two mounting frames 6, two mounting frames 6 are installed in the feeding belt 5, the adjacent side of the two mounting frames 6 is respectively fixedly connected with the threaded cylinder 22 and rotatably connected with the screw rod 14, and the screw rod 14 is threadedly connected in the threaded cylinder 22.

The bottom end of the compression spring 21 is fixedly connected to the extrusion plate 17. The bottom end of the extrusion plate 17 is embedded with a clamping ball. The two positioning blocks 15 are both provided with a clamping groove matched with the clamping ball. When the L-shaped fork plate 3 is swung 90° by the fixed shaft 9, the clamping ball at the bottom end of the extrusion plate 17 is automatically inserted into the clamping groove of the positioning block 15, thereby avoiding the swing of the L-shaped fork plate 3 when the moving plate 13 moves, and ensuring the use stability of the L-shaped fork plate 3. The workpiece on the feeding mechanism can be taken off and conveyed more accurately. When the fixed shaft 9 pulls the reset through the moving plate 13, the clamping ball at the bottom end of the extrusion plate 17 will be separated from the positioning block 15, thereby ensuring the reset effect of the L-shaped fork plate 3.
