[0002] Heat treatment refers to a metal hot processing technology in which the material is heated, kept warm and cooled in the solid state to obtain the expected structure and performance. In order to improve the quality of the processing technology, tooling is usually used to assist it, so as to complete the operations such as the workpiece entering and exiting the furnace and the clamping during the heating and cooling process, so as to reduce the deformation of the workpiece during heat treatment.

[0003] A heat treatment tool disclosed in the Chinese utility model (Announcement No.: CN219490099U) solves the problem that the heat treatment quality of the spring is easily affected by the current method of hanging the spring, and can perform uniform heat treatment processing on the spring through the rotation and revolution of the spring, thereby improving the heat treatment quality of the spring.

[0004] In the process of realizing the utility model, the inventor found that there are at least the following problems in the technology: in the prior art, multiple hollow shaft sleeves are arranged on the outside of the corresponding support shafts, and the hollow shaft sleeves are placed on the outside of the support shafts, and the springs are fixed by the abutment plate and the support plate. Since the length of the hollow sleeves is the same, it is impossible to effectively fix springs of different specifications at the same time, which leads to low adaptability of the equipment. Therefore, a heat treatment tool is now proposed. Utility Model Content

[0034] The following is combined with Figure 1-5 This application is described in further detail.

[0035] Please refer to Figure 1-5 A heat treatment tool comprises a heat treatment box 1, a cover plate 2 is arranged on the upper side of the heat treatment box 1, the cover plate 2 is fixedly connected to the heat treatment box 1 through a buckle 3, a connecting shaft 4 is rotatably connected inside the cover plate 2, a connecting plate 5 is fixedly connected to the lower side of the connecting shaft 4, a sleeve 6 is fixedly connected to the lower side of the connecting plate 5, an adjusting mechanism 7 is fixedly connected to the lower side of the sleeve 6, a fixed shaft 8 is slidably connected to the adjusting mechanism 7, a connecting plate 9 is rotatably connected to the outer side of the fixed shaft 8, and a transmission mechanism 10 is arranged on the lower side of the fixed shaft 8;

[0036] The adjusting mechanism 7 includes a connecting tube 71, an elastic component 72, a clamping component 73, a limiting component 74 and a chuck 75. The connecting tube 71 is sleeved inside the sleeve 6, the connecting tube 71 is sleeved on the outside of the fixed shaft 8, the elastic component 72 is fixedly connected to the inside of the connecting tube 71, the clamping component 73 is fixedly connected to the inside of the connecting tube 71, the limiting component 74 is fixedly connected to the upper side of the clamping component 73, and the chuck 75 is sleeved on the outside of the fixed shaft 8.

[0037] It should be further explained that the transmission mechanism 10 is composed of a motor, a gear and a gear ring. Please refer to the comparative case and no further explanation is given here.

[0038] Reference Figure 2 and Figure 3When the locking cam 724 is in the state of being lifted up, the locking cam 724 will be in the state of being lifted up, and the locking cam 724 will be in the state of being lifted up.

[0039] Reference Figure 2 and Figure 3 The clamping assembly 73 includes a threaded rod 731, a clamping block 732 and an abutment plate 733. The threaded rod 731 is rotatably connected to the connecting tube 71, the clamping block 732 is threadedly connected to the threaded rod 731, the clamping block 732 is slidably connected to the connecting tube 71, and the side of the threaded rod 731 away from the connecting tube 71 is fixedly connected to the abutment plate 733. More specifically, when it is necessary to clamp the workpiece, by rotating the threaded rod 731, the threaded rod 731 and the clamping block 732 undergo threaded movement, so that the clamping block 732 is displaced to clamp the workpiece. In this way, the workpiece that is inconvenient to fix on both sides can be clamped and fixed.

[0040] Reference Figure 2 and Figure 3 There are two clamping assemblies 73, and the two clamping assemblies 73 are symmetrically distributed on both sides of the connecting tube 71. More specifically, by setting a plurality of clamping assemblies 73, the force on the workpiece is more uniform and the clamping is more stable.

[0041] Reference Figure 2 and Figure 3 A groove is provided on the abutment plate 733. More specifically, during the process of clamping the workpiece, the groove on the abutment plate 733 cooperates with the limiting assembly 74 to prevent the threaded rod 731 from rotating.

[0042] Reference Figure 2 and Figure 3 A protrusion is provided on one side of the clamping block 732. More specifically, in the process of clamping the workpiece, the friction between the clamping block 732 and the workpiece is increased by providing the protrusion, so that the fixation of the workpiece is more stable.

[0043] Reference Figure 2 and Figure 3 The limiting assembly 74 includes a support plate 741, a connecting block 742 and a clamping block 743. The support plate 741 is fixedly connected to the outer side of the connecting tube 71, the connecting block 742 penetrates and is sleeved inside the support plate 741, and the extended end of the connecting block 742 is fixedly connected to the clamping block 743, and the clamping block 743 contacts the abutment disk 733. More specifically, when it is necessary to rotate the threaded rod 731, the connecting block 742 is moved in the direction away from the support plate 741, and the connecting block 742 drives the clamping block 743 to move. When the clamping block 743 moves to the groove that is out of the abutment disk 733, the threaded rod 731 can be rotated.

[0044] Reference Figure 2 and Figure 3 The shape of the block 743 matches the groove on the abutment plate 733. More specifically, the abutment plate 733 is limited by the matching block 743 and the groove of the abutment plate 733 to prevent the abutment plate 733 from driving the threaded rod 731 to rotate.

[0045] When the workpiece is clamped, the connecting block 742 drives the clamping block 743 to be inserted into the groove on the abutment plate 733 to limit it, thereby preventing the abutment plate 733 and the threaded rod 731 from rotating.

[0046] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
