Through the meshing and cooperation of multiple groups of transmission gears, the linkage of each mechanism of the machine can be realized, thereby completing some complex mechanical movements. With the continuous development of industrial mechanization, the quality requirements for transmission gears are getting higher and higher. Since the meshing force of the transmission gears in some large machines is relatively large, the transmission gears need to have high strength.

A limiting groove is opened at the bottom of the inner side of each clamping block. The two limiting grooves form a circle after being docked with the placement groove. The clamping block is horizontally slidably connected to the top of the first support block. A first spring located between the clamping block and the L-shaped fixing frame is sleeved on the outer surface of each first lead screw;

[0008] The feeding mechanism includes two first fixing plates respectively fixedly connected to the front and rear sides of the fixed bottom plate.

[0009] The heating mechanism includes a number of first connecting frames all fixedly connected to the top of the fixed bottom plate. Two heating plates arranged vertically are fixedly connected together among the number of first connecting frames. The two heating plates are used for heating the transmission gears continuously conveyed to the right;

[0010] The rotating mechanism includes a second gear fixedly connected to the outer surface of the mounting rod. The second gear is located outside the clamping mechanism. A second rack is fixedly connected together by a number of first connecting frames on the same side.

DETAILED DESCRIPTION OF THE INVENTION

[0033] Please refer to Figures 1-9, the present invention provides a technical solution: a continuous heat treatment production device for transmission gears, including a fixed bottom plate 1. At the top of the fixed bottom plate 1, two first tooth chains 2 are connected in a driving manner. A number of clamping mechanisms are connected to the outer surfaces of the two first tooth chains 2 and are evenly distributed along the edges of the first tooth chains 2 at equal intervals. An installation mechanism is clamped inside each clamping mechanism, and the installation mechanism is used to install the transmission gears. Above the fixed bottom plate 1, a heating mechanism is provided between the two first tooth chains 2. Above the fixed bottom plate 1, a feeding mechanism is connected, which is used to put the installation mechanism and the transmission gears into the clamping mechanism when the clamping mechanism moves to the upper left. At the top of the fixed bottom plate 1, a discharging mechanism is connected, which is used to open the clamping mechanism to discharge the installation mechanism and the transmission gears when the clamping mechanism moves to the lower right. Above the fixed bottom plate 1, a rotating mechanism is connected, which is used to drive the installation mechanism and the transmission gears to rotate when the transmission gears pass through the heating mechanism;

[0034] When the device is working, start the two first tooth chains 2 to drive the clamping mechanism to rotate clockwise. When the first tooth chain 2 drives the clamping mechanism to move below the feeding mechanism, the feeding mechanism opens the clamping mechanism, and the operator puts the installation mechanisms of multiple transmission gears into the clamping mechanism. Then, start the first tooth chain 2 again to drive the installation mechanism and the transmission gears to move to the right. Similarly, the next clamping mechanism reaching the feeding mechanism continues to be fed, so as to continuously feed and process the transmission gears. When the first tooth chain 2 drives the installation mechanism and the transmission gears to leave the feeding mechanism, the clamping mechanism clamps and positions the installation mechanism to prevent the transmission gears from detaching from the clamping mechanism during the movement, improving the stability of transportation. When the installation mechanism and the transmission gears are about to move into the heating mechanism, the installation mechanism is acted upon by the rotating mechanism and starts to rotate continuously, driving the transmission gears to rotate. Then, it moves into the heating mechanism for rotational heating, thereby performing circumferential heating treatment on the transmission gears. When the transmission gears are moved out from the right end of the heating mechanism, the heating of the transmission gears is completed. The first tooth chain 2 continues to drive the installation mechanism and the transmission gears to move below the first tooth chain 2. When the transmission gears and the installation mechanism are driven to move to the left, the discharging mechanism opens the clamping mechanism and automatically discharges the heat-treated installation mechanism and the transmission gears to the right. Finally, take the processed transmission gears off the installation mechanism, then load the transmission gears that need heat treatment, and put the installation mechanism and the transmission gears into the clamping mechanism again to complete the heat treatment of one transmission gear. Thus, when performing heat treatment on the transmission gears each time, by using the two first tooth chains 2 in cooperation with the clamping mechanism, the installation mechanism, the feeding mechanism, and the discharging mechanism, the feeding, rotational heat treatment, and discharging of the transmission gears are automatically and continuously completed, greatly improving the processing efficiency, saving labor costs, and having a high degree of automation of the equipment, avoiding frequent operation by personnel and avoiding injuries to personnel during frequent operation.

[0035] As a further solution of the present invention, the installation mechanism includes an installation rod 3. A first stop bar 4 is vertically slidably connected inside the installation rod 3. The first stop bar 4 and the installation rod 3 are connected by a plurality of second springs 5. The plurality of second springs 5 are used to extrude the first stop bar 4 outwards. The plurality of second springs 5 are all located inside the installation rod 3. During operation, since multiple transmission gears need to be separately installed and the installed transmission gears need to be stabilized, by pressing the first stop bar 4 inwards to compress the second springs 5 and pressing the first stop bar 4 into the installation rod 3, then, the transmission gears to be heat-treated are loaded onto the installation rod 3, and a gap is maintained between the multiple transmission gears. Then, the first stop bar 4 is released, and the first stop bar 4 pops outwards under the action of the second springs 5 and presses against the inner side wall of the transmission gear, pressing the transmission gear tightly, so as to keep the multiple gears stable during subsequent heat treatment.

[0036] As a further solution of the present invention, the clamping mechanism includes a first support block 6. The first support block 6 is fixedly connected to the outer surface of the first tooth chain 2. A placement groove 7 is opened at the top of the first support block 6. L-shaped fixing frames 8 are fixedly connected to both the left and right sides of the first support block 6. A first lead screw 9 that is slidably connected thereto penetrates through each L-shaped fixing frame 8. A clamping block 10 is fixedly connected to the inner end of each first lead screw 9. A limiting groove 11 is opened at the bottom of the inner side of each clamping block 10. The two limiting grooves 11 form a circle after being docked with the placement groove 7. The clamping block 10 is horizontally slidably connected to the top of the first support block 6. A first spring 12 located between the clamping block 10 and the L-shaped fixing frame 8 is sleeved on the outer surface of each first lead screw 9. During operation, since it is necessary to drive the installation mechanism and the transmission gears to be slowly driven and heated, after the two clamping blocks 10 are pulled outwards and opened by the feeding mechanism, the installation rod 3 is placed in the placement groove 7 at the top of the two first support blocks 6. Then, the first tooth chain 2 drives the installation rod 3 and the transmission gears to continue to move to the right. The two first springs 12 squeeze the clamping blocks 10 inwards, causing the two clamping blocks 10 to approach each other and finally come into contact with each other, clamping the top of the installation rod 3, so as to stabilize the installation rod 3 and the transmission gears, which is beneficial to subsequent heat treatment of the transmission gears.

[0037] As a further solution of the present invention, the feeding mechanism includes two first fixing plates 13, which are respectively fixedly connected to the front and rear sides of the fixed bottom plate 1. Guide blocks 14 are fixedly connected to the inner side walls of the two first fixing plates 13. The two guide blocks 14 are used to squeeze the front and rear ends of the mounting rod 3. Two first racks 15 are fixedly connected to the inner side walls of the two first fixing plates 13. The first racks 15 are located above the first tooth chain 2. The two first racks 15 are arranged in a front-back staggered manner. A worm 16 is rotatably connected to the left side of each L-shaped fixing frame 8. A turbine 17 is rotatably connected to the outer side wall of each L-shaped fixing frame 8. The turbine 17 is sleeved on the outer surface of the first lead screw 9 and is threadedly connected to the first lead screw 9. A first gear 18 is fixedly connected to the outer end of each worm 16. The first gear 18 meshes with the first rack 15. During operation, since the mounting rod 3 needs to be continuously placed into the clamping mechanism, when the first tooth chain 2 drives the first support block 6 and the clamping block 10 to move to the right, the two first gears 18 arranged in a front-back staggered manner move to the left end of the first rack 15. When continuing to move to the right, the first gear 18 is rotated by the action of the first rack 15, driving the worm 16 to rotate, driving the turbine 17 to rotate, the turbine 17 drives the first lead screw 9 to move outwards, stretching the first spring 12, and the first lead screw 9 drives the clamping block 10 to move outwards, so as to pull the two clamping blocks 10 outwards to open, facilitating the subsequent placement of the mounting rod 3 on the top of the first support block 6 by the operator for feeding.

[0038] As a further solution of the present invention, the heating mechanism includes a plurality of first connecting frames 19, which are all fixedly connected to the top of the fixed bottom plate 1. Two heating plates 20 arranged up and down are fixedly connected together among the plurality of first connecting frames 19. The two heating plates 20 are used to heat-treat the transmission gears that are continuously conveyed to the right. During operation, since the transmission gears that continuously move to the right need to be heat-treated, when the first tooth chain 2 drives a plurality of transmission gears to move to the right through the clamping mechanism and the mounting mechanism, the two heating plates 20 are started to heat, and the transmission gears that move between the two heating plates 20 are heat-treated, which is convenient and fast. And the two heating plates 20 are arranged inside the two first tooth chains 2 to prevent the first tooth chain 2 from being heated for a long time.

[0039] As a further solution of the present invention, the rotating mechanism includes a second gear 21, which is fixedly connected to the outer surface of the mounting rod 3, and the second gear 21 is located on the outer side of the clamping mechanism. Several first connecting frames 19 on the same side are fixedly connected with a second rack 22, and both ends of the second rack 22 are longer than the heating plate 20, and the second rack 22 is used to mesh with the top of the second gear 21; during operation, since there are teeth all around the outer surface of the transmission gear, when the upper and lower heating plates 20 heat the transmission gear, the distance from the upper and lower ends of the transmission gear is close, and the heating degree is different. Before each transmission gear moves to the heating mechanism, the second gear 21 fixedly connected to the outer surface of the mounting rod 3 meshes with the second rack 22. When continuing to move to the right, the second gear 21 is driven to rotate, thereby driving the mounting rod 3 and multiple transmission gears to rotate together, which is beneficial to uniformly heating the transmission gear circumferentially, and the second rack 22 is located above the second gear 21 to prevent the mounting rod 3 from tilting upward.

[0040] As a further solution of the present invention, the discharging mechanism includes two second fixed plates 23, the two second fixed plates 23 are fixedly connected to the fixed base plate 1, and the two second fixed plates 23 are respectively located on the outer sides of the two first toothed chains 2, and two third racks 24 are fixedly connected to the inner side walls of the two second fixed plates 23, and the two third racks 24 are arranged front and back in a staggered manner, and the third rack 24 is used to be on the left and right of the first gear 18, and the third rack 24 is located below the first toothed chain 2, and a guide plate 25 for guiding the fallen transmission gear to the right is connected to the top of the fixed base plate 1; during operation, since the processed rear transmission gear needs to be discharged in time after the heating treatment is completed, when the transmission gear leaves the heating mechanism and moves to the bottom of the first toothed chain 2, the two first gears 18 act on the two third racks 24 respectively, and when the transmission gear moves to the left side, the first gear 18 and the worm 16 are driven to rotate again, and the two clamping blocks 10 are driven to open outward again, so that the mounting rod 3 and the transmission gear fall together and roll out to the right along the guide plate 25, and the discharging is automatically completed, which is convenient and fast.

[0041] As a further solution of the present invention, two second support frames 26 located outside the first fixing plate 13 are fixedly connected to the top of the fixed base plate 1. Two second tooth chains 27 arranged in two groups left and right are drivingly connected between the two second support frames 26. A number of equally spaced first stoppers 28 are fixedly connected to the outer surface of each second tooth chain 27. The left and right first stoppers 28 are flush with each other when rotating to the inside. The two second tooth chains 27 drive towards each other to drop the installation mechanism and the transmission gear into the opened clamping mechanism. The bottom of the second support frame 26 is connected with a detector 29 for detecting the position of the clamping mechanism. During operation, since after the feeding mechanism opens the clamping mechanism each time, the installation rod 3 needs to be placed. If it is placed manually, the labor intensity is too high and the accuracy is difficult to grasp. After the detector 29 detects the position of the clamping mechanism each time, two second tooth chains 27 are started, so that the two second tooth chains 27 drive inward together. The operator places the installation mechanism and the transmission gear that need to be placed in the clamping mechanism in advance between the two second tooth chains 27. The first stopper 28 rotating to the inside stably supports the installation rod 3 above. When the second tooth chains 27 drive inward synchronously, it drives the placed installation rod 3 to move downward. The two bottom first stoppers 28 open outward, dropping the installation rod 3 and the transmission gear onto the first support block 6, thus completing automatic and accurate feeding, without excessive participation of personnel, improving the processing efficiency and saving labor.

[0042] A continuous heat treatment process for transmission gears, and the specific steps of the process are as follows:

[0043] Step 1: Start two first tooth chains 2 to drive the clamping mechanism to rotate clockwise. When the first tooth chains 2 drive the clamping mechanism to move below the feeding mechanism, the feeding mechanism opens the clamping mechanism and places the installation mechanisms of a plurality of transmission gears into the clamping mechanism.

[0044] Step 2: Start the first tooth chain 2 again to drive the installation mechanism and the transmission gear to move to the right, and the clamping mechanism clamps and positions the installation mechanism.

[0045] Step 3: When the installation mechanism and the transmission gear are about to move into the heating mechanism, the installation mechanism is acted on by the rotating mechanism and starts to rotate continuously, driving the transmission gear to rotate, and moving into the heating mechanism for rotational heating.

[0046] Step 4: When the transmission gear moves out from the right end of the heating mechanism, the heating of the transmission gear is completed. The first tooth chain 2 continues to drive the installation mechanism and the transmission gear to move below the first tooth chain 2. The discharging mechanism opens the clamping mechanism and automatically discharges the heat-treated installation mechanism and the transmission gear to the right.

[0047] Step Five: Remove the processed transmission gear from the installation mechanism, then load the transmission gear that needs heat treatment in the incoming row, and put the installation mechanism and the transmission gear into the clamping mechanism again to complete the heat treatment of one transmission gear.

The first tooth chain (2) continues to drive the installation mechanism and the transmission gear to move below the first tooth chain (2), and the discharging mechanism opens the clamping mechanism and automatically discharges the heat-treated installation mechanism and the transmission gear to the right. Step 5: Remove the processed transmission gear from the installation mechanism, then load the transmission gear that needs to be heat-treated in the next batch, and put the installation mechanism and the transmission gear into the clamping mechanism again to complete the heat treatment of one transmission gear.
