Sprockets are widely used in mechanical transmissions in industries such as chemical industry, textile machinery, escalators, instrumentation, petroleum, etc. Sprockets need to bear a relatively high load during operation. Therefore, in order to improve their surface hardness and strength to adapt to the high-load working environment, the produced sprockets need to be quenched.

[0003] In the use of existing sprocket processing and quenching equipment, the sprocket is mostly placed on the workbench, then the sprocket is placed in the middle of the high-frequency electric heating tube, and then power is supplied to the high-frequency electric heating tube to generate high temperature to heat the surface of the sprocket in the middle. Then, the heated sprocket is cooled to achieve the quenching processing of the sprocket. However, since the high-frequency electric heating tube is directly exposed, it may cause the staff to accidentally touch the surface of the high-frequency electric heating tube during operation, resulting in accidental scalding of the staff and affecting the operation safety.

[0029] Refer to Figure 2 and Figure 3 As shown in the figure, this embodiment discloses that the protection device 5 includes a rectangular frame 51. A connecting device 6 is arranged between the rectangular frame 51 and the machine body 1. A first round-hole block 53 is slidably connected to the inner wall of the rectangular frame 51. A positioning rod 52 is fixedly connected to the inner wall of the rectangular frame 51. The inner wall of the first round-hole block 53 is slidably connected to the surface of the positioning rod 52. A spring 55 is fixedly connected to one side of the first round-hole block 53. The other end of the spring 55 is fixedly connected to the inner wall of the rectangular frame 51. The spring 55 is sleeved on the surface of the positioning rod 52. A protective cover 54 is fixedly connected to one side of the first round-hole block 53. The inner wall of the protective cover 54 is larger than the surface of the high-frequency electric heating tube 3. By setting the protection device 5, first assemble the rectangular frame 51 with the machine body 1 through the connecting device 6. At this time, under the reaction force of the spring 55, the spring 55 pushes the first round-hole block 53 to move along the inside of the rectangular frame 51 towards the direction close to the high-frequency electric heating tube 3, so that the first round-hole block 53 slides along the surface of the positioning rod 52, and the first round-hole block 53 drives the protective cover 54 to move towards the direction close to the high-frequency electric heating tube 3. When the first round-hole block 53 moves to the maximum position inside the rectangular frame 51 under the push of the spring 55, the protective cover 54 moves to a position where the high-frequency electric heating tube 3 is completely wrapped to intercept external objects, thereby completing the protection of external workers, reducing the situation that personnel accidentally touch the surface of the high-frequency electric heating tube 3 during operation and causing burns to personnel, and improving the operation safety of personnel.

When the circular cover 511 moves to the position where it is inserted into the circular through-hole 59, the inner wall of the circular hole plate 512 coincides with the inner wall of the first threaded hole 510. At this time, rotate the screw 513 with a tool so that the screw 513 is screwed into the circular hole plate 512 and the first threaded hole 510 to fix the circular cover 511, achieving the assembly of the electric fan 514 and the protective cover 54. At this time, drive the electric fan 514 by a motor so that the electric fan 514 generates wind and blows towards the high-frequency electric heating tube 3, so that the blown air flow blows onto the surface of the sprocket inside the high-frequency electric heating tube 3 to assist in cooling it, further improving the cooling efficiency of the sprocket.

At this time, manually move the plug 57 so that the plug 57 moves to the position where it is inserted into the circular hole 56 and the first round hole block 53 to fix the position of the first round hole block 53, thereby achieving the retraction and fixation of the protective cover 54, which is convenient for the operator to operate on the sprocket inside the high-frequency electric heating tube 3. One end of the plug 57 is fixedly connected with an elastic cord 58, and the other end of the elastic cord 58 is fixedly connected with the rectangular frame 51. By setting the elastic cord 58, the elastic cord 58 can tow the plug 57, reducing the situation that the plug 57 falls and gets lost after being pulled out of the circular hole 56.

[0032] Referring to Figure 3 and Figure 4As shown in the figure, this embodiment discloses that the connecting device 6 includes a rectangular cylinder 61.

The surface of the second round hole block 66 is slidably inserted into the inner wall of the rectangular cylinder 61. The size and shape of the surface of the bolt 63 are adapted to the size and shape of the inner wall of the second round hole block 66. By setting the connecting device 6, first manually move the rectangular frame 51 so that the rectangular frame 51 drives the second round hole block 66 to move. When the second round hole block 66 moves to a position where it is completely inserted into the rectangular cylinder 61, the inner wall of the second round hole block 66 coincides with the inner wall of the second threaded hole 62.

When the second round hole block 66 moves to a position where it is completely inserted into the rectangular cylinder 61, the inner wall of the second round hole block 66 coincides with the inner wall of the second threaded hole 62. At this time, manually rotate the screwing block 64 so that the screwing block 64 drives the bolt 63 to rotate, and the bolt 63 is screwed into the second threaded hole 62 and the inner position of the second round hole block 66 to fix the positions of the second round hole block 66 and the rectangular frame 51, thus completing the rapid assembly of the protection device 5 and the machine body 1. At this time, the rectangular frame 51 is assembled with the machine body 1 through the connecting device 6. At this time, under the reaction force of the spring 55, the spring 55 pushes the first round hole block 53 to move along the inside of the rectangular frame 51 towards the direction close to the high-frequency electric heating tube 3, so that the first round hole block 53 slides along the surface of the positioning rod 52, and the first round hole block 53 drives the protective cover 54 to move towards the direction close to the high-frequency electric heating tube 3. When the first round hole block 53 moves to the maximum position inside the rectangular frame 51 under the push of the spring 55, the protective cover 54 moves to a position where it completely wraps the high-frequency electric heating tube 3 and intercepts external objects, thus completing the protection of external workers. At this time, place the sprocket on the lifting platform 4 so that the sprocket is placed in the middle of the high-frequency electric heating tube 3. Subsequently, supply power to the high-frequency electric heating tube 3 to generate high temperature to heat the surface of the sprocket in the middle, and then cool the heated sprocket to achieve the quenching process of the sprocket.
