Specifically, as shown in fig. 7, rotate seat 1507 and keep away from one side of dwang 1506 and the bottom outer wall fixed connection of fixed shell 1601, conveniently drive fixed shell 1601 and rotate simultaneously when rotating seat 1507 rotates, the outer wall of arc piece 1509 and the inner wall sliding connection of arc groove 1508, arc piece 1509 slides at the inner wall of arc groove 1508, has played the effect of leading to fixed shell 1601.

The working principle is as follows: when the brake disc is used, the brake disc body 18 is conveniently driven to move up and down through the arrangement of the lifting cylinder 19, the support frame 20 and the lifting block 21, when the lifting cylinder 19 is started, the support frame 20 moves, the lifting block 21 and the support frame 20 move simultaneously, the position of the brake disc body 18 is conveniently adjusted, the brake disc body is conveniently moved to the top of the lower clamping plate 1611 to be contacted with the top of the lower clamping plate, the clamping and the fixing are convenient, and the practicability is better;

the brake disc body 18 is conveniently clamped and fixed through the arrangement of the clamping device 16, the brake disc body 18 can be prevented from loosening during turning, the using effect is better, the hydraulic cylinder 1608 is started to drive the connecting block 1609 to move towards one side of the embedded groove 1602, the lower clamping plate 1611 moves towards one side of the brake disc body 18 along with the connecting block, the attaching block 1610 moves and drives the movable rod 1613 to rotate anticlockwise when the connecting block 1609 moves, the movable rod 1613 drives the upper clamping plate 1604 to move downwards, one end of the upper clamping plate 1604 slides on the inner wall of the strip-shaped sliding groove 1603, the limiting block 1605 is driven to slide downwards on the inner wall of the limiting groove 1606, the upper clamping plate 1604 and the lower clamping plate 1611 approach gradually, the lower clamping plate 1611 is firstly contacted with the bottom of the brake disc body 18 to play a role of stable support, when the upper clamping plate 1604 is contacted with the top of the brake disc body 18 and mutually clamped and fixed, the first wedge block 1607 and the second wedge block 1612 have large, the anti-skidding effect is good, clamping and fixing are facilitated, turning is carried out at the same time, damage to people due to overhigh surface temperature of the brake disc body 18 is avoided, fixing and clamping are facilitated, the annealing effect is good, and the annealing efficiency is high;

through turn-over device 15's setting, the convenience carries out automatic turn-over to brake disc body 18, make the bottom of brake disc body 18 be heated evenly, the holistic scope of being heated of brake disc is more comprehensive, with the fixed back of 18 centre grippings of brake disc body, start turn-over cylinder 1501 and drive transfer bar 1502 and remove to the right side, transfer bar 1502 drives when removing and rotates support 1504 and remove simultaneously, then set casing 1601 anticlockwise rotation, dwang 1506 rotates simultaneously and drives elastic block 1510 and slides at the inner wall of arc wall 1508, set casing 1601 rotates simultaneously with the brake disc body 18 of centre gripping, conveniently carry out the turn-over to brake disc body 18, the holistic scope of being heated of brake disc is more comprehensive, annealing effect is better, and the practicality is better.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
