Description

Technical Field

[0001] The invention belongs to the field of gear processing devices, in particular to a gear processing production device. Background Art

[0002] At present, most gears are made of carbon structural steel. During the processing and manufacturing of gears, they need to undergo quenching treatment to greatly improve the rigidity, hardness, wear resistance, fatigue strength and toughness of the steel, so as to meet the use requirements of the gears. In the quenching process of the gears, high-frequency quenching is often used for quenching.

[0003] In the prior art, the existing high-frequency quenching is generally performed by placing the parts in an induction coil for heating and then placing them in a cooling liquid for rapid cooling to change the ferrite structure. During the high-frequency quenching operation, workers are required to manually and intermittently place a single gear in the induction coil. After heating, the workers use clamps or other components to take the gear out of the quenching equipment and place it in the cooling liquid for cooling. In this process, the operation speed is slow, the production efficiency is low, the labor load of the workers is heavy, and the temperature of the quenching equipment is high when working, which can easily burn the hands of the workers. Therefore, it does not meet the existing needs.

[0004] A Chinese patent with authorization announcement number CN110629011B discloses an automatic quenching device for gear processing, which relates to the technical field of gear processing. The device is provided with face teeth on the upper and lower surfaces of a carrier plate. When the carrier plate is driven up by a cylinder during use, the carrier plate can be disengaged from the rotating central axis to stop the rotation of the carrier plate. At the same time, high-frequency heating of the gear parts is achieved through the meshing of the intermediate pulley and the part carrier. When the heating is completed, the carrier plate is driven down by the cylinder, and the carrier plate is re-engaged with the rotating central axis. The rotating central axis drives the carrier plate to rotate and takes the gear parts away. The gear parts are automatically transported to the induction coil for heating and then away from the induction coil by the cylinder, and the gear parts are placed in the cooling liquid under the action of the separation guide rail. In this process, all actions are completed by the intermittent lifting and lowering of the cylinder to solve the problems of slow operation speed, low production efficiency and heavy labor load of workers in the existing high-frequency quenching process.

[0005] However, the above patent still has the following disadvantages:

[0006] 1. According to the description of the above patent, when performing the gear quenching process, the above patent still needs to intermittently carry out the steps of installing the gear, heating the gear, and dropping the gear into the quenching medium for quenching. It is difficult to truly realize continuous and efficient gear quenching processing, which wastes a lot of time and affects production efficiency.

[0007] 2. When the above-mentioned patent is performing the quenching process on the gears, after the heated gears fall into the quenching medium contained in the machine body, the workers are unable to take out the quenched gears in time because the above-mentioned patent continues to operate. The above-mentioned patent can only be shut down after running for a certain period of time, and the workers have to manually take out the gears, which wastes working time and affects efficiency. Summary of the invention

[0008] In order to overcome the deficiencies of the prior art, the present invention solves the technical problem of achieving continuous and stable transportation of a target gear by setting a gear conveying chain formed by a plurality of first chain plates hinged end to end, so as to facilitate a continuous induction heating process, and when the target gear moves to the rotating position at the end of the gear conveying chain, the target gear automatically falls under the action of gravity, so as to facilitate quenching processing, and by setting an induction heating chain formed by a plurality of second chain plates hinged end to end, each induction coil can cooperate with the movement of the target gear, and synchronously perform induction heating on the target gear during the moving and conveying process of the target gear, thereby achieving continuous and efficient quenching processing and improving production efficiency, and by setting an inclined conveyor belt, the quenched gear can be automatically salvaged, which is convenient for workers to collect and does not affect the continuous quenching processing of the gear, thereby reducing the labor intensity of workers without affecting the processing efficiency.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a gear processing and production device includes a frame 10, two first wheel shafts 13 are rotatably connected between the two frames 10, a group of first sprockets 14 are fixedly connected to each first wheel shaft 13, a gear conveying chain is drivingly connected between the two groups of first sprockets 14, the gear conveying chain is formed by a plurality of first chain plates 15 hinged end to end, each first chain plate 15 is hinged to each other through a first pin shaft 19, each first sprocket 14 is meshingly connected to the end of the corresponding first pin shaft 19, a bearing 36 is arranged between each mounting rod 35 and the first chain plate 15, a fixing ring 37 surrounding the outer side of the mounting rod 35 is fixedly connected to each first chain plate 15, and a target gear 39 is placed on the end of the mounting rod 35 located above.

[0034] By setting up a gear conveying chain formed by multiple first chain plates 15 hinged end to end, continuous and stable conveying of the target gear 39 is achieved, so as to facilitate a continuous induction heating process, and when the target gear 39 moves to the rotating point at the end of the gear conveying chain, the target gear 39 automatically falls under the action of gravity, so as to facilitate quenching processing.

[0035] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, two shaft frames 11 are fixedly connected to each frame 10, a second axle 16 is rotatably connected between each two opposite shaft frames 11, a group of second sprockets 17 are fixedly connected to each second axle 16, an induction heating chain is transmission-connected between the two groups of second sprockets 17, and the induction heating chain is formed by a plurality of second chain plates 18 hinged end to end, each second chain plate 18 is hinged to each other through a second pin shaft 20, each second sprocket 17 is meshingly connected to the corresponding end of the second pin shaft 20, a coil sleeve 40 is fixedly connected to the surface of each second chain plate 18, an induction coil 41 is fixedly connected inside each coil sleeve 40, and each induction coil 41 located below is sleeved on the outside of the target gear 39.

[0036] By setting up an induction heating chain formed by multiple second chain plates 18 hinged end to end, each induction coil 41 can cooperate with the movement of the target gear 39, and synchronously perform induction heating on the target gear 39 during the movement and transportation of the target gear 39, thereby achieving continuous and efficient quenching processing and improving production efficiency.

[0037] like Figure 2 , Figure 5 and Figure 6 As shown, a bracket 22 is fixedly connected to one of the frames 10, and the end of the bracket 22 faces above the gear conveyor chain. A rack 33 is fixedly connected to the end of the bracket 22, and a driving gear 38 that can mesh with the rack 33 is fixedly connected to the outer side of each mounting rod 35.

[0038] By setting the rack 33 and the driving gear 38, during the process of conveying the target gear 39, the driving gear 38 and the rack 33 can be meshed and transmitted, so that the mounting rod 35 drives the target gear 39 to rotate, and the target gear 39 can rotate at a uniform speed during the induction heating process, so as to ensure the uniformity of the induction heating of the gear and improve the quality of the gear after quenching.

[0039] like Figure 2 , Figure 6 and Figure 8 As shown, a conductive rail 34 is fixedly connected above the rack 33, a docking protrusion 44 is provided on the outer side of each coil sleeve 40 close to the conductive rail 34, two ends of each induction coil 41 are bent out from the docking protrusion 44, and two brushes 42 are fixedly connected to the surface of each docking protrusion 44, each brush 42 is electrically connected to one end of the induction coil 41, and each brush 42 can be in close contact with the conductive rail 34 and slide relative to it.

[0040] By providing the brush 42 and the conductive rail 34 , the induction coil 41 in the working area can be powered in real time when the induction coil 41 is running along with the induction heating chain, so that the induction coil 41 can perform induction heating on the target gear 39 .

[0041] like Figure 1 , Figure 3 and Fig. 9 As shown, the shapes of the first sprocket 14 and the second sprocket 17 are exactly the same, a transmission housing 27 is fixedly connected to the outer side of one of the shaft frames 11, the first wheel shaft 13 and the second wheel shaft 16 located at the corresponding positions of the transmission housing 27 extend into the transmission housing 27 and are respectively fixedly connected to worm wheels 31, a transmission shaft 30 is rotatably connected at the corresponding positions of the two worm wheels 31 in the transmission housing 27, two worms 32 with opposite screw directions are respectively fixedly connected at the corresponding positions of each worm wheel 31 on the transmission shaft 30, each worm 32 is meshed and transmission-connected with the corresponding worm wheel 31, an end cover 28 is fixedly connected to the end of the transmission housing 27, a second motor 29 is fixedly connected to the top of the transmission housing 27, and a power output end of the second motor 29 is transmission-connected to the transmission shaft 30.

[0042] By providing a worm wheel 31 and two worms 32 with opposite screw directions, the gear heating chain and the induction heating chain are synchronously driven, thereby ensuring that the induction coil 41 can be stably aligned with the target gear 39 during the process of conveying the target gear 39, thereby ensuring the stability of the induction heating.

[0043] like Figure 1 , Figure 3 and Figure 4 As shown, a first limit plate 12 is fixedly connected between the two frames 10 at the inner side of the gear conveyor chain, and the upper surface of the first limit plate 12 is tightly fitted with the bottom side of the upper first chain plate 15 and slides relative to each other. A second limit plate 21 is fixedly connected above the two frames 10, and the second limit plate 21 passes through the inner side of the induction heating chain and is tightly fitted with the surface of the lower second chain plate 18 and slides relative to each other.

[0044] By setting the first limiting plate 12, each first chain plate 15 can be supported and restricted, thereby ensuring that the first chain plate 15 can move more stably when conveying the target gear 39, thereby ensuring the stability of the target gear 39 when moving. Similarly, by setting the second limiting plate 21, each second chain plate 18 can be limited, thereby ensuring the stability of each induction coil 41 when moving, ensuring that each induction coil 41 can maintain a stable and accurate relative position with the corresponding target gear 39, and ensuring the quality of induction heating.

[0045] A quenching box 23 is fixedly connected to one end of the frame 10, and the quenching box 23 is located below the end of the gear conveyor chain. Two belt rollers 25 are rotatably connected in the quenching box 23, and a conveyor belt 24 is transmission-connected between the two belt rollers 25. The conveyor belt 24 is inclined, and a plurality of ridges 43 are evenly distributed on the surface of the conveyor belt 24. A first motor 26 is fixedly connected to the outer side of the quenching box 23 at a position corresponding to a belt roller 25, and a power output end of the first motor 26 is transmission-connected to the corresponding belt roller 25.

[0046] By setting up an inclined conveyor belt 24, the gears after quenching can be automatically salvaged, which is convenient for workers to collect and does not affect the continuous quenching process of the gears, thereby reducing the labor intensity of workers without affecting the processing efficiency. The quenching box 23 is made of heat-insulating material, and the transmission belt 24, belt roller 25 and ridge 43 are made of heat-resistant materials.

[0047] In this embodiment, initially, the worker connects the power supply and control system of this patent, and connects the conductive rail 34 to the power supply, and then injects a sufficient amount of quenching medium into the quenching box 23 so that the quenching medium at least submerges three-quarters of the conveyor belt 24, and sets an automatic loading device at one end of the gear conveyor chain. Then the worker starts the second motor 29 and the first motor 26 at the same time through the control system. At this time, the second motor 29 drives the transmission shaft 30 to drive the two worm gears 32 to rotate.

[0048] Since the two worm gears 32 have opposite spiral directions, the two worm gears 32 running at the same speed and direction will drive the two worm wheels 31 to run at the same speed and in opposite directions. Since the shapes of the first sprocket 14 and the second sprocket 17 are exactly the same, the gear conveying chain and the induction heating chain can run in opposite directions at the same speed.

[0049] While the gear conveyor chain is constantly being adjusted, workers simultaneously use automatic loading equipment to install the target gears 39 to be quenched one by one on the end of the mounting rod 35. The target gear 39 moves with the operation of the gear conveyor chain, and as the target gear 39 gradually moves to the bottom of the induction heating chain, the corresponding coil sleeve 40 and the induction coil 41 will gradually be sleeved on the outside of the target gear 39, and finally be transported and moved together with the target gear 39.

[0050] When the induction coil 41 is sleeved on the outside of the target gear 39 and moves therewith, the corresponding brush 42 will contact and slide, thereby energizing the induction coil 41 sleeved on the outside of the target gear 39, and then induction heating the target gear 39. Due to the limitation of the second limiting plate 21, the brush 42 can stably contact the conductive rail 34 for power supply.

[0051] At the same time, since the driving gear 38 moves with the target gear 39 and the driving gear 38 contacts and meshes with the rack 33, the driving gear 38 drives the mounting rod 35 to rotate, thereby causing the target gear 39 to rotate continuously, so that the induction coil 41 can heat the target gear 39 more evenly during the process of induction heating of the target gear 39, thereby ensuring the uniformity of the gear after subsequent quenching.

[0052] After the target gear 39 is evenly heated, the target gear 39 moves to the rotation point of the gear conveying chain. At this time, the induction coil 41 is separated from the target gear 39 along with the rotation upward of the induction heating chain, and the brush 42 is separated from the conductive rail 34 and is no longer connected to the power supply. The target gear 39 rotates downward along with the gear conveying chain. During the rotation downward process, the target gear 39 naturally falls into the quenching medium under the action of gravity to complete the quenching.

[0053] When the target gear 39 is quenched, the operation of the first motor 26 causes the conveyor belt 24 to continuously rotate upward, and the target gear 39 that has fallen into the quenching box 23 and has been quenched is continuously transported out of the quenching box 23 by the conveyor belt 24. A collection device is provided at the end of the quenching box 23 to automatically complete the collection of the quenched gears, which greatly saves manpower and does not affect the processing efficiency.

[0054] The first motor 26 , the second motor 29 , the conductive rail 34 , the bearing 36 , and the brush 42 are mature existing technologies and will not be described in detail herein.
