Positioning cross bars 463 are evenly and fixedly connected to the curved side walls of the mounting ring 462. A guide groove 4631 is provided on the top of the positioning cross bar 463. A movable column 464 is movably engaged inside the guide groove 4631. Both ends of the movable column 464 extend to the outside of the ports at both ends of the guide groove 4631. A mounting shell 467 is fixedly connected to the outer wall of the end of the movable column 464 away from the positioning ring 461. A movable ball 468 is movably engaged inside the mounting shell 467. One end of the movable ball 468 extends to the outside of the port of the mounting shell 467.

[0035] The exposed end of the movable ball 468 extends to the outside of the port of the mounting ring 462, and the movable ball 468 is symmetrically distributed in a cross shape on the outside of the mounting ring 462. The movable balls 468 on the first clamping plate 46 and the second clamping plate 47 are arranged one by one corresponding to each other, and are all suspended between the corresponding positioning horizontal bars 463 on the first clamping plate 46 and the second clamping plate 47.

[0036] The supporting turntable 31 is a hollow structure, and driven gears 311 are movably provided on the bottom plate thereof corresponding to the rotating shaft 45.

[0037] Specifically, all the electric lifting rods 41 on the top of the supporting turntable 31 are controlled to rise, and the electric lifting rods 41 push the fixing rods 42 upward to drive the second mounting bar 44 and the second clamping plate 47 at the end thereof to move upward, so that they are separated from the first clamping plate 46 at the end of the first mounting bar 43, and the brake disc body 5 is placed horizontally on the top of the first clamping plate 46 in sequence, so that the raised end at the middle of the brake disc body 5 is suspended against the inner side of the protruding moving ball 468 on the mounting ring 462, and the first mounting bar 43, the positioning ring 461, the mounting ring 462 and the positioning cross bar 46 are used. 3 cooperates with the moving column 464 and the moving ball 468 to limit and lift the brake disc body 5, and then controls the electric lifting rod 41 to descend and reset, so that the rotating moving ball 468 at the bottom of the second clamping plate 47 is pressed and fitted to the top of the brake disc body 5, thereby completing the clamping and fixing of the brake disc body 5.

After the heating of the brake disc body 5 is completed, it is kept at a constant temperature in the heating chamber for a period of time, and finally the height of the supporting turntable 31 is lowered by the hydraulic lifting rod 3, so that the brake disc bodies 5 stacked on the top placement frame 4 are all immersed in the quenching oil in the cooling chamber for rapid cooling, thereby completing the heat treatment of the brake disc body 5.

[0038] In order to facilitate the heat treatment of brake discs of different specifications, such as Figure 3-Figure 6 As shown, this embodiment provides the following technical solutions:

[0039] The guide slot 4631 is arranged through the upper and lower end surfaces of the positioning cross bar 463, and a guide rod 465 is fixedly connected between the inner walls of the two ends of the guide slot 4631 perpendicular to the arc side wall of the mounting ring 462, and the guide rod 465 movably passes through the movable column 464, and a buffer spring 466 is wound on the outer wall of the guide rod 465 between the side wall of the movable column 464 and the inner wall at the end of the guide slot 4631, and the lower end of the movable column 464 extends to the bottom of the positioning cross bar 463, and a movable connecting rod 469 is movably connected to the bottom of the movable column 464, and the end of the movable connecting rod 469 is movably connected to the side wall of the positioning ring 461.

[0040] The interior of the mounting ring 462 is provided with an annular cavity 4621, the port of the annular cavity 4621 extends to the outer wall of the mounting ring 462 near the port of one end of the positioning ring 461, one end of the positioning ring 461 is movably inserted into the annular cavity 4621, and a limiting groove 4611 is provided on the outer wall of the positioning ring 461 in the annular cavity 4621, the cross section of the limiting groove 4611 is a fan-shaped structure, and the limiting blocks 4612 are evenly spaced and fixedly connected on the flat bottom plate of the limiting groove 4611, and the annular cavity 4621 is provided with a limiting groove 4611. A limiting rod 4622 is evenly and movably connected to the corresponding limiting groove 4611 on the inner wall, a torsion spring 4623 is fixedly connected to the outer wall on one side of the limiting rod 4622, and the other end of the torsion spring 4623 is fixedly connected to the inner wall of the annular cavity 4621, and a moving rod 4624 is movably connected to the side wall at the middle section of the limiting rod 4622, and the end of the moving rod 4624 extends through the outside of the mounting ring 462 away from the end of the positioning ring 461, and the end of the moving rod 4624 is fixedly connected to an annular plate 4625.

[0041] The annular plate 4625, the mounting ring 462 and the positioning ring 461 are coaxially arranged, and when the torsion spring 4623 maintains a normal relaxation state, the annular plate 4625 is suspended outside the port of the mounting ring 462.

The end of the annular cover 4626 is movably engaged in the annular groove on the outer wall at the port of the mounting ring 462.

[0042] Specifically, the annular plate 4625 is pressed to move it close to the mounting ring 462, and the annular plate 4625 pushes the moving rod 4624 to move into the annular cavity 4621 in the mounting ring 462, and the moving rod 4624 pushes the end of the limiting rod 4622 to deflect toward the side close to the positioning ring 461, thereby squeezing the torsion spring 4623, so that the end of the limiting rod 4622 is separated from the spacing groove formed by the limiting block 4612 set on the flat bottom plate of the limiting groove 4611, thereby controlling the limiting rod 4622 to unlock the positioning ring 461, while maintaining the pressing posture and driving the mounting ring 462 to rotate. When the mounting ring 462 rotates, the moving column 464 in turn pushes the movable connecting rod 469 to deflect within a certain angle based on the fixed point on the side wall of the positioning ring 461, and the other end of the movable connecting rod 469 pushes the moving column 464 moves along the guide groove 4631 and the guide rod 465, thereby adjusting the distance between the moving column 464 and the moving ball 468 in the guide groove 4631 and the side wall of the mounting ring 462, so as to resist and lift the middle raised end of the brake disc body 5 of different specifications, keep the rotation angle of the mounting ring 462 stable and release the annular plate 4625 at the same time, and the limit rod 4622 automatically resets under the action of the torsion spring 4623, and the end of the limit rod 4622 deflects and moves again to the partition groove formed by the corresponding two limit blocks 4612 on the flat bottom plate of the limit groove 4611. The limit block 4612 restricts the limit rod 4622 to prevent the mounting ring 462 and the positioning ring 461 from rotating and resetting under the buffer spring 466, thereby maintaining the stability of the adjustment of the distance between the moving ball 468 and the side wall of the mounting ring 462.

[0043] like Figure 3-Figure 4 and Figure 8-Figure 9 As shown, in order to facilitate the heating and immersion of the brake disc body 5 in the quenching oil and then to turn and rotate it to avoid the heating dead angle and quenching oil residue, this embodiment provides the following technical solutions:

[0045] Mounting cavities 4811 are evenly spaced inside the edges of the mounting plate 481 corresponding to the movable groove 485, an elastic component 4812 is fixedly connected to the bottom plate of the mounting cavity 4811, the end of the elastic component 4812 is fixedly connected to the outer wall of the movable plate 4813, the movable plate 4813 is movably engaged in the mounting cavity 4811, the other end of the movable plate 4813 is fixedly connected to the connecting rod 486, the other end of the connecting rod 486 extends through to the outside of the curved side wall of the mounting plate 481, the end of the connecting rod 486 outside the mounting plate 481 is fixedly connected to a spherical head 487, the spherical head 487 is movably engaged in the movable groove 485, and buffer protrusions 488 are evenly spaced and fixedly connected to the outer wall of the toggle bar 484 away from the mounting plate 481.

[0046] Specifically, when the rotating shaft 45 drives the mounting plate 481 to rotate, the mounting plate 481 pushes the toggle bar 484 to slide against the curved side wall of the brake disc body 5 based on the positioning bar 482. When the toggle bar 484 slides against the brake disc body 5 based on the buffer protrusion 488 on the outer wall, it is deflected and squeezed, thereby driving the brake disc body 5 to rotate under the clamping of the moving balls 468 at its upper and lower ends, thereby preventing the brake disc body 5 from excessively contacting the placement rack 4 during heating to form a contact dead angle and affect the heating. The toggle bar 484 in turn pushes the connecting rod 486 toward the mounting cavity 48 on the mounting plate 481. 11 moves inside, the connecting rod 486 pushes the movable plate 4813 to compress the elastic component 4812, and when the end of the toggle bar 484 slides over the curved side wall of the brake disc body 5 and separates, the toggle bar 484 ejects and accelerates the brake disc body 5 based on the micro-elastic deformation, so as to speed up the rotation speed of the brake disc body 5 clamped by the moving ball 468, so that after the brake disc body 5 is heated and cooled by immersion in quenching oil, the excess quenching oil attached to the surface of the brake disc body 5 is separated and recovered by the rotation of the brake disc body 5, thereby avoiding the waste of quenching oil and facilitating the drying of the brake disc body 5, which is easy to use.
