By placing the two ends of the workpiece on the cross - bars, the support for the workpiece is achieved. After retrieval, the patent with the application number 202322209184.X discloses a workpiece heat treatment device, which includes two cross - bars and a support assembly. The cross - bars have a plurality of grooves. The support assembly includes two support frames, two sliding rods, a hollow column, and a driving part; the two support frames are respectively fixedly connected to the two cross - bars, the two sliding rods are respectively fixedly connected to the two support frames, the hollow column is respectively slidably connected to the two sliding rods, and the driving part is arranged on the hollow column.

[0003] However, during the actual use process, the applicant found that after adjusting the distance between the two cross - bars, it is locked by inserting a pin between two adjacent teeth on a rack. This kind of locking method causes a certain movement of the cross - bar during the locking process, resulting in inaccurate adjustment of the distance between the two cross - bars. In view of this, we propose a workpiece heat treatment device. Content of the Utility Model

[0020] Please refer to Figures 1-3 as shown in the figure, the present invention provides a technical solution:

[0021] A workpiece heat treatment device includes an intermediate seat 1. On both sides of the intermediate seat 1, there are symmetrically and movably connected connecting plates 2. At the bottom of one end of the connecting plate 2 located inside the intermediate seat 1, there is fixedly arranged a connecting sliding column 21. At the bottom of the intermediate seat 1, there is fixedly arranged a driving box 11. Inside the intermediate seat 1, there is a rotating shaft 6 rotatably connected by a bearing. The lower end of the rotating shaft 6 is rotatably connected to the driving box 11 through a bearing. A driving disk 7 is sleeved and fixed on the rotating shaft 6 below the connecting plate 2. The bottom of the connecting plate 2 is in contact with the top of the driving disk 7. The driving disk 7 is provided with arc-shaped connecting sliding grooves 71 symmetrically centered. The connecting sliding column 21 slides along the arc-shaped connecting sliding groove 71. The lower end of the connecting sliding column 21 movably penetrates through the arc-shaped connecting sliding groove 71. A worm gear 8 is sleeved and fixed on the rotating shaft 6 below the driving disk 7. In the driving box 11 on one side of the worm gear 8, there is a worm 9 rotatably connected by a bearing. The front end of the worm 9 extends to the outside of the driving box 11 and is fixedly connected with a hand crank 91. The worm 9 is in transmission connection with the worm gear 8. By rotating the worm 9 to drive the worm gear 8 to rotate, the rotating shaft 6 can be driven to rotate together with the driving disk 7. Furthermore, through the cooperation of the arc-shaped connecting sliding groove 71 and the connecting sliding column 21, the two connecting plates 2 can be driven to slide along the inner side wall of the intermediate seat 1, so as to quickly adjust the distance between the two beam frames 3, enabling the device to adapt to the storage of workpieces of different lengths. And the cooperation of the worm 9 and the worm gear 8 has a self-locking function, making the adjustment more accurate. One end of the connecting plate 2 located outside the intermediate seat 1 is fixedly connected with a beam frame 3. At the bottom of both ends of the beam frame 3, there are symmetrically fixedly connected brake wheels 5, making the movement of the beam frame 3 more convenient, thus facilitating the personnel to adjust the distance between the two beam frames 3. The top of the beam frame 3 is fixedly connected with a limit support seat 4. On the inner side wall of the limit support seat 4, there is a workpiece placement groove 41. During the heat treatment process, the distance between the two limit support seats 4 can be adjusted according to the length of the half shaft type. During adjustment, the hand crank 91 can be manually rotated to drive the worm 9 to rotate. The rotation of the worm 9 can drive the worm gear 8 and the rotating shaft 6 to rotate together. The rotation of the rotating shaft 6 can drive the driving disk 7 to rotate. The rotation of the driving disk 7 can drive the two connecting plates 2 to approach or move away synchronously through the cooperation of the arc-shaped connecting sliding groove 71 and the connecting sliding column 21. Furthermore, the two beam frames 3 can be driven to approach or move away synchronously, so as to drive the limit support seat 4 to move and quickly adjust the distance between the two limit support seats 4. After adjusting the two limit support seats 4 to an appropriate distance, stop rotating the worm 9. At this time, the worm 9 and the worm gear 8 can achieve self-locking, effectively locking the distance between the two limit support seats 4. Furthermore, the two ends of the half shaft type workpiece can be respectively placed in the workpiece placement grooves 41 opened on the two limit support seats 4 to store the half shaft type workpiece.

[0022] The width of the workpiece placement groove 41 on the inner wall of the limit support seat 4 gradually increases in the front-back direction. There are four workpiece placement grooves 41 opened along the front-back direction on the inner side wall of the limit support seat 4. The workpiece placement groove 41 has a certain depth, which can realize the stacked placement of the same type of half-axis workpieces, thereby improving the storage capacity of the workpieces, can realize the storage of half-axis workpieces with different shaft diameters, has stronger applicability. When storing half-axis workpieces, according to the shaft diameter of the half-axis workpiece, it can be selected and stored in a suitable group of workpiece placement grooves 41, and the workpiece placement groove 41 with a certain depth can realize the stacked placement of the same type of half-axis workpieces.

[0023] Working principle: When in use, during the heat treatment process, the distance between the two limit support seats 4 can be adjusted according to the length of the half-axis. When adjusting, the worm 9 can be driven to rotate by manually rotating the hand crank 91. The rotation of the worm 9 can drive the worm wheel 8 and the rotating shaft 6 to rotate together. The rotation of the rotating shaft 6 can drive the driving disk 7 to rotate. The rotation of the driving disk 7 can drive the two connecting plates 2 to approach or move away synchronously through the cooperation of the arc-shaped connecting chute 71 and the connecting sliding column 21, and then can drive the two beam frames 3 to approach or move away synchronously, thereby driving the limit support seat 4 to move, quickly adjusting the distance between the two limit support seats 4. After adjusting the two limit support seats 4 to the appropriate distance, stop rotating the worm 9. At this time, the worm 9 and the worm wheel 8 can achieve self-locking, effectively locking the distance between the two limit support seats 4. Then, the two ends of the half-axis workpiece can be respectively placed in the workpiece placement grooves 41 opened on the two limit support seats 4 to store the half-axis workpiece. When storing the half-axis workpiece, according to the shaft diameter of the half-axis workpiece, it can be selected and stored in a suitable group of workpiece placement grooves 41, and the workpiece placement groove 41 with a certain depth can realize the stacked placement of the same type of half-axis workpieces.
