It is connected to a support frame 8, on which a rotating mechanism 9 is installed, on which a number of rotatable rotating containing frames 10 are installed, and on which a number of clamping mechanisms 14 for fixing automobile brake pads 15 are installed; on the inner wall of the furnace body 1 near the bottom are connected a number of hot air output pipes 7, which are connected to a hot air blower, and the heat blown out by the hot air blower is blown into the furnace body 1 through the hot air output pipes 7 to heat-treat the automobile brake pads 15; an exhaust pipe is installed on the top surface of the furnace body 1, and a rear pressure gauge and an exhaust valve are installed on the exhaust pipe. When the air pressure in the furnace body 1 exceeds a preset value, the exhaust valve opens to exhaust air outwards.

[0031] like Figure 5 As shown, the rotating mechanism 9 includes two rotating components arranged symmetrically front and back, and the rotating components are installed on the support frame 8. The two rotating components are connected together through a connecting shaft 9-7. A driving shaft 9-8 is rotatably installed on the support frame 8 through a bearing. The driving shaft 9-8 is connected to the driving motor 9-12 located on the outside of the furnace body 1 through a docking structure, and the driving shaft 9-8 and the connecting shaft 9-7 are connected through a transmission assembly; the transmission assembly includes a first sprocket 9-9 and a second sprocket 9-10, the first sprocket 9-9 is arranged on the driving shaft 9-8, and the second sprocket 9-10 is arranged on the connecting shaft 9-7, and the first sprocket 9-9 and the second sprocket 9-10 are connected by a chain 9-11.

[0032] The rotating assembly includes a plurality of connecting plates 9-2, and the plurality of connecting plates 9-2 are connected in sequence to form a runway-type rotating chain. A plurality of mounting plates 9-6 are installed on the rotating chain. A driving wheel 9-3 is installed at the connection between two adjacent connecting plates 9-2.

A runway-type limiting groove 9-5 matching the limiting wheel 9-4 is provided on the support frame 8. The limiting wheel 9-4 moves in the limiting groove 9-5. A rotating disk 9-1 is installed on the connecting shaft 9-7, and a plurality of grooves engaging with the driving wheel 9-3 are evenly provided on the rotating disk 9-1.

[0033] A rotary storage frame 10 is arranged between two of the mounting plates 9-6 corresponding to the front and rear positions. The left and right sides of the rotary storage frame 10 are connected with mounting shafts 11. The mounting shafts 11 are rotatably connected to the mounting plates 9-6 through bearings. As Figure 1 , 4 , as shown in Fig. 11, gears 12 are installed at the ends of the mounting shafts 11. Rack bars 13 meshing with the gears 12 are installed on the left and right sides of the support frame 8. When the gears 12 move upward or downward along the rack bars 13, the gears 12 will rotate, thereby driving the rotary storage frame 10 to rotate on its own axis.

A spline groove is formed on the inner wall of the connection sleeve 9-13. A docking portion 9-8-1 is connected to the end of the drive shaft 9-8. Splines matching the spline groove are connected to the outer wall of the docking portion 9-8-1. The docking portion 9-8-1 is inserted into the connection sleeve 9-13. The output shaft of the drive motor 9-12 drives the connection sleeve 9-13 to rotate. Through spline cooperation, the connection sleeve 9-13 drives the drive shaft 9-8 to rotate. The rotation of the drive shaft 9-8 drives the first sprocket 9-9 to rotate. The rotation of the first sprocket 9-9 drives the second sprocket 9-10 to rotate through a chain 9-11. The rotation of the second sprocket 9-10 drives the connection shaft 9-7 to rotate. The rotation of the connection shaft 9-7 drives the rotating disk 9-1 to rotate. The rotation of the rotating disk 9-1 drives the rotating chain to rotate, thereby driving a plurality of rotary storage frames 10 to move upward along with the rotating chain.

[0035] As Figure 8-9 shown, the cross-section of the rotary storage frame 10 is a regular hexagon. A plurality of rectangular mounting frames are arranged on six faces. Clamping mechanisms 14 are installed in the rectangular mounting frames. As Figure 10As shown, the clamping mechanism 14 includes two symmetrically arranged fixed frames 14-1. On the sides of the two fixed frames 14-1 close to each other, U-shaped card slots 14-1-1 are provided. The automotive brake pads 15 are arranged between two card slots 14-1-1 with corresponding positions. On both sides of the two fixed frames 14-1, connecting screws 14-2 are provided. The two ends of the connecting screws 14-2 are connected to the inner wall of the rectangular installation frame. Four locking nuts 14-3 for positioning the fixed frames 14-1 are threadedly connected to the connecting screws 14-2. The outer side of the fixed frame 14-1 is a plane, and the inner side of the fixed frame 14-1 is an inclined surface. An installation groove 14-1-2 is provided on the inclined surface. One locking nut 14-3 is provided on both the installation groove 14-1-2 and the outer side of the plane. The position of the fixed frame 14-1 can be locked by these two locking nuts 14-3. During actual use, the position of the fixed frame 14-1 can be adjusted to change the distance between the two fixed frames 14-1, and further make the distance between the two card slots 14-1-1 match the size of the automotive brake pads 15, so as to clamp automotive brake pads 15 of different models. The width of the card slot 14-1-1 can be larger than the thickness of the automotive brake pads 15, because the automotive brake pads 15 are mainly tightened in the length direction by the two card slots 14-1-1, and after the size in the width direction increases, it can match automotive brake pads 15 of different models.

[0036] The working process of the present invention is as follows:

[0037] First, place the automotive brake pads 15 to be processed on the clamping mechanism 14. After placing the automotive brake pads 15 on multiple rotating storage frames 10, open the furnace door 2, push the feeding trolley 5 into the furnace body 1, and insert the docking part 9-8-1 of the drive shaft 9-8 into the connecting sleeve 9-13 to complete the docking work. Subsequently, close the furnace door 2, and the drive motor 9-12 drives multiple rotating storage frames 10 to move upward from bottom to top along with the rotating chain, so that multiple rotating storage frames 10 pass through the position of the hot air output pipe 7 in turn, and multiple rotating storage frames 10 are evenly heated. At the same time, when the rotating storage frame 10 moves upward or downward, the gear 12 moves along the rack 13. During the movement of the gear 12, it will rotate, thereby driving the rotating storage frame 10 to rotate self, and the heating is more uniform.
