[0014] A method for using a gear heat treatment processing device, the method comprising:

[0015] S1. Open the box cover of the left side box, and then place the multiple gears to be heat treated in the multiple circular grooves respectively, and then start the lifting motor to drive one of the lifting screws to rotate, and drive the other lifting screw to rotate synchronously under the meshing action of the two first sprockets and the first chain, so that the two U-shaped lifting blocks drive the rotating disk and the multiple cylinders to move downward synchronously. When the two lifting screws are rotating, the two connecting shafts are driven to rotate synchronously through the meshing action of the two worms and the two worm wheels, and the two moving screws are driven to rotate synchronously through the meshing action of the four second sprockets and the two second chains, and then the two rectangular extrusion sliders are driven to slide horizontally to the right synchronously under the action of the thread. When the rectangular extrusion slider starts to slide, the rectangular slide is in a stationary state. When the rectangular extrusion slider slides to the inner wall of the other side of the U-shaped slider, the U-shaped slider is extruded, thereby driving the rectangular slide to move horizontally synchronously, and the multiple gears to be heat treated are transported to the processing box;

[0016] S2. When the right side of the rectangular slide contacts the inner side of the right side box, the right induction switch transmits an electrical signal to the left hydraulic cylinder and the right hydraulic cylinder, so that the left hydraulic cylinder and the right hydraulic cylinder synchronously drive the U-shaped slider to move horizontally, and the movement speed is the same as the horizontal movement speed of the rectangular extrusion slider, so that the rectangular slide stops moving, and the two U-shaped lifting blocks drive the rotating disk to continue to move downward, so that multiple cylinders can be inserted from the center holes and circular holes of multiple gears to be processed respectively, and the cross clamping blocks at the bottom of multiple circular plates are respectively connected with multiple cross rotating sleeves, and then multiple clamping motors are started, and the cross rotating sleeve, cross clamping block, circular plate, and two-way rotating sleeve are driven by the clamping motor. The screw rod rotates synchronously, and then drives the two square slides to move synchronously towards each other under the action of the thread, and drives the four arc-shaped extrusion plates to move synchronously away from the axis under the action of multiple connecting rods, clamping and fixing the inner wall of the peripheral side of the gear to be processed. When it is necessary to drive the rotating disk to reset, the two lifting screw rods are driven to reverse through the lifting motor, thereby driving the two U-shaped lifting blocks and the rotating disk to move upward synchronously. When the two lifting screws just start to rotate, the two moving screws are driven to reverse synchronously through the cooperation, thereby driving the two rectangular extrusion slide blocks to move to the left. At this time, the rectangular slide seat is still in a stationary state, so that multiple cylinders can slide out of multiple round holes without causing jamming;

[0017] S3. During the heat treatment process, the rotating motor is started to drive the cross sleeve and the cross slide bar to rotate synchronously, and then the rotating disk is driven to rotate synchronously.

[0019] In summary, the technical effects and advantages of the present invention are as follows:

[0020] 1. In the present invention, when the two lifting screws are rotating, the two connecting shafts are driven to rotate synchronously through the meshing action of the two worms and the two worm wheels, and the two moving screws are driven to rotate synchronously through the meshing action of the four second sprockets and the two second chains, and then the two rectangular extrusion sliders are driven to slide horizontally to the right synchronously under the action of the threads. When the rectangular extrusion slider slides at the beginning, the rectangular slide is in a stationary state. When the rectangular extrusion slider slides to the inner wall of the other side of the U-shaped slider, the U-shaped slider is squeezed, thereby driving the rectangular slide to move horizontally synchronously, and transporting multiple gears to be heat treated into the processing box.

[0021] 2. In the present invention, when the right side of the rectangular slide contacts the inner side of the right side box, the right sensing switch, the left hydraulic cylinder and the right hydraulic cylinder cooperate to drive the U-shaped slider to move horizontally, and the movement speed is the same as the horizontal movement speed of the rectangular extrusion slider, so that the rectangular slide stops moving, and the two U-shaped lifting blocks drive the rotating disk to continue to move downward, and the multiple cylinders are respectively inserted into the center holes and circular holes of the multiple gears to be processed, and the cross blocks at the bottom of the multiple circular plates are respectively engaged with the multiple cross rotating sleeves, and then the inner wall of the peripheral side of the gear to be processed is clamped and fixed by the clamping assembly, which is more convenient to operate.

[0022] 3. In the present invention, during the heat treatment process, the rotating motor is started to drive the cross sleeve and the cross slide bar to rotate synchronously, and then drive the rotating disk to rotate synchronously. When the rotating disk rotates, it drives multiple self-rotating gears to engage with multiple annular internal racks, thereby driving multiple cylinders and multiple gears to be processed to rotate synchronously. With this arrangement, the gears to be processed can rotate and revolve, so that a uniform heat treatment function can be achieved, and the treatment effect is better.

[0044] A method for using a gear heat treatment processing device, the method comprising:

[0045] S1. Open the box cover 38 of the left side box 19, and then place the multiple gears to be heat treated in the multiple circular grooves respectively, and then start the lifting motor 6 to drive one of the lifting screws 2 to rotate, and drive the other lifting screw 2 to rotate synchronously under the meshing action of the two first sprockets 4 and the first chain 5, so that the two U-shaped lifting blocks 3 drive the rotating disk 7 and the multiple cylinders 11 to move downward synchronously. When the two lifting screws 2 are rotating, the two connecting shafts 25 are driven to rotate synchronously through the meshing action of the two worms 28 and the two worm wheels 29, and the two moving screws 24 are driven to rotate synchronously through the meshing action of the four second sprockets 26 and the two second chains 27, and then the two rectangular extrusion sliders 23 are driven to slide horizontally to the right synchronously under the action of the thread. When the rectangular extrusion slider 23 starts to slide, the rectangular slide 21 is in a stationary state. When the rectangular extrusion slider 23 slides to the inner wall of the other side of the U-shaped slider 22, the U-shaped slider 22 is squeezed, thereby driving the rectangular slide 21 to move horizontally synchronously, and the multiple gears to be heat treated are transported to the processing box 1;

[0046] S2. When the right side of the rectangular slide 21 contacts the inner side of the right side box 19, the right induction switch 34 transmits an electrical signal to the left hydraulic cylinder 31 and the right hydraulic cylinder 32, so that the left hydraulic cylinder 31 and the right hydraulic cylinder 32 synchronously drive the U-shaped slide 22 to move horizontally, and the movement speed is the same as the horizontal movement speed of the rectangular extrusion slide 23, so that the rectangular slide 21 stops moving, and the two U-shaped lifting blocks 3 drive the rotating disk 7 to continue to move downward, so that the multiple cylinders 11 can be respectively moved from the center holes of the multiple gears to be processed. , and insert the cross blocks 37 at the bottom of the multiple circular plates 14 into the multiple cross rotating sleeves 35 respectively, and then start the multiple clamping motors 36, and drive the cross rotating sleeves 35, the cross blocks 37, the circular plates 14, and the bidirectional screw rods 15 to rotate synchronously through the clamping motors 36, and then drive the two square slides 16 to move synchronously towards each other under the action of the threads, and drive the four arc-shaped extrusion plates 17 to move synchronously away from the axis under the action of the multiple connecting rods 18, so as to clamp and fix the inner wall of the peripheral side of the gear to be processed;

During the heat treatment process, the rotating motor 9 is started to drive the cross sleeve 8 and the cross slide bar 10 to rotate synchronously, and then the rotating disk 7 is driven to rotate synchronously. When the rotating disk 7 rotates, the multiple self-rotating gears 12 are driven to mesh with the multiple annular inner racks 13, thereby driving the multiple cylinders 11 and the multiple gears to be processed to rotate synchronously;

[0048] S4. After the heat treatment operation is completed, the above operation is repeated, and the multiple processed gears are placed back on the top of the multiple circular grooves and the clamping and fixing function is released, and then they are transported to the side box 19 for easy removal after cooling.

[0049] Working principle of the present invention: when loading is required, first open the box cover 38 of the left side box 19, then place multiple gears to be heat treated in the multiple circular grooves respectively, and then start the lifting motor 6 to drive one of the lifting screws 2 to rotate, and drive the other lifting screw 2 to rotate synchronously under the meshing action of the two first sprockets 4 and the first chain 5, so that the two U-shaped lifting blocks 3 drive the rotating disk 7 and multiple cylinders 11 to move downward synchronously.

[0050] When the two lifting screws 2 are rotating, the two connecting shafts 25 are driven to rotate synchronously through the meshing action of the two worms 28 and the two worm wheels 29, and the two moving screws 24 are driven to rotate synchronously through the meshing action of the four second sprockets 26 and the two second chains 27, and then the two rectangular extrusion sliders 23 are driven to slide horizontally to the right synchronously under the action of the threads. When the rectangular extrusion slider 23 starts to slide, the rectangular slide 21 is in a stationary state. When the rectangular extrusion slider 23 slides to the inner wall of the other side of the U-shaped slider 22, the U-shaped slider 22 is squeezed, thereby driving the rectangular slide 21 to move horizontally synchronously, and transporting multiple gears to be heat treated into the processing box 1.

[0051] When the right side of the rectangular slide 21 contacts the inner side of the right side box 19, the right induction switch 34 transmits an electrical signal to the left hydraulic cylinder 31 and the right hydraulic cylinder 32, so that the left hydraulic cylinder 31 and the right hydraulic cylinder 32 synchronously drive the U-shaped slider 22 to move horizontally, and the movement speed is the same as the horizontal movement speed of the rectangular extrusion slider 23, so that the rectangular slide 21 stops moving, and the two U-shaped lifting blocks 3 drive the rotating disk 7 to continue to move downward, so that the multiple cylinders 11 can be inserted into the center holes and circular holes of the multiple gears to be processed respectively, and the cross blocks 37 at the bottom of the multiple circular plates 14 are respectively engaged with the multiple cross rotating sleeves 35, and then the multiple clamping motors 36 are started, and the cross rotating sleeves 35, the cross blocks 37, the circular plates 14, and the bidirectional screw rods 15 are driven to rotate synchronously by the clamping motors 36, and then Under the action of the thread, the two square slides 16 are driven to move synchronously toward each other, and under the action of multiple connecting rods 18, the four arc-shaped extrusion plates 17 are driven to move synchronously in the direction away from the axis, so as to clamp and fix the inner wall of the peripheral side of the gear to be processed. With this arrangement, the synchronous feeding and clamping function of multiple gears to be processed can be realized without releasing the equipment, and the efficiency is relatively high. When it is necessary to drive the rotating disk 7 to reset, the two lifting screws 2 are driven to reverse through the lifting motor 6, thereby driving the two U-shaped lifting blocks 3 and the rotating disk 7 to move upward synchronously. When the two lifting screws 2 just start to rotate, the two moving screws 24 are driven to reverse synchronously through the coordinated action, thereby driving the two rectangular extrusion sliders 23 to move to the left. At this time, the rectangular slide 21 is still in a stationary state, so that the multiple cylinders 11 can slide out of the multiple circular holes without causing jamming.

[0052] During the heat treatment process, the rotating motor 9 is started to drive the cross sleeve 8 and the cross slide bar 10 to rotate synchronously, and then drive the rotating disk 7 to rotate synchronously. When the rotating disk 7 rotates, it drives multiple self-rotating gears 12 to engage with multiple annular internal racks 13, thereby driving multiple cylinders 11 and multiple gears to be treated to rotate synchronously. With this arrangement, the gears to be treated can rotate and revolve on their own, so that a uniform heat treatment function can be achieved, and the treatment effect is better.

[0053] After the heat treatment operation is completed, the above operation is repeated, and the multiple processed gears are placed back on the top of the multiple circular grooves and the clamping and fixing function is released, and then they are transported to the side box 19 for easy removal after cooling. This arrangement effectively prevents high-temperature burns to the staff and has strong protection.
