Description

Technical Field

[0001] This invention relates to the field of gear manufacturing technology, and more specifically to a continuous heat treatment equipment for gears. Background Technology

[0002] High-frequency heat treatment equipment for gears is a specialized device for strengthening gear surfaces based on the principle of electromagnetic induction. It rapidly heats the gear tooth surface through a high-frequency coil, and then sprays coolant to complete the quenching process. The equipment features fast heating speed, minimal workpiece deformation, and minimal oxidation and decarburization. It can precisely form a structure with a hard surface and a tough core, effectively improving the wear resistance and fatigue resistance of gears. It is widely used in the batch surface heat treatment of various gears in automobiles and engineering machinery.

[0003] Chinese patent CN111996357A discloses a fully automated gear heat treatment production line, relating to the field of gear production equipment. It involves fixing a cooling tank on a high-frequency machine frame, setting a first conveyor structure in front of the cooling tank, and a second conveyor structure behind the cooling tank. A lifting structure is located at one end of the first conveyor structure, with the cantilever end of the lifting structure positioned below the high-frequency machine's worktable. Linear guide rails are provided on the inner wall of the cooling tank, and a placement plate is mounted on the slider of the linear guide rails. A first gantry robot grips the gear and places it at the cantilever end of the lifting structure for heating. After heat treatment, the lifting structure descends, and the gear falls onto the placement plate, then is conveyed to the other end of the cooling tank via the linear guide rails. During its descent after heat treatment, the gear enters the coolant, achieving rapid cooling and improving the high-frequency machine's processing efficiency. The gear is completely immersed in and surrounded by the coolant, resulting in a large heat exchange area and improved heat exchange efficiency. However, this device still has the following problems:

[0004] For gears that are thick and cannot be fully heated by a single heating coil, the device requires the installation of multiple sets of high-frequency heating coils.

[0012] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0013] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0014] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-3 A gear-based continuous heat treatment device, comprising an indexing plate 1; The fully automatic loading and unloading mechanism 2 for automatically loading and unloading gear 4 is installed on the drive end of the indexing plate 1. The single-drive synchronous cooling mechanism 3, which is used to heat and cool the gear 4 and is synchronously linked with the fully automatic loading and unloading mechanism 2, is located at the front end of the indexing plate 1. The single-drive synchronous cooling mechanism 3 includes an alignment and locking assembly 31, a rotary drive assembly 32, a reciprocating vertical movement assembly 33, and a heating and quenching assembly 34. The alignment and locking assembly 31, which links the fully automatic loading and unloading mechanism 2 with the rotary drive assembly 32, is mounted on the fully automatic loading and unloading mechanism 2. The rotary drive assembly 32, which drives the alignment and locking assembly 31 and the reciprocating vertical movement assembly 33, is located at the front end of the indexing plate 1. The reciprocating vertical movement assembly 33, which drives the heating and quenching assembly 34 to move vertically reciprocally, is mounted on the rotary drive assembly 32. The heating and quenching assembly 34, which performs high-frequency heating and cooling of the gear 4, is mounted on the reciprocating vertical movement assembly 33. The alignment and locking assembly 31 is connected to the fully automatic loading and unloading mechanism 2.

[0015] In this invention, after the operator starts the equipment, the fully automatic loading and unloading mechanism 2 drives the gear 4 into the loading station. Then, the fully automatic loading and unloading mechanism 2 fixes the gear 4 internally and rotates it to the processing station. Then, the component that fixes the gear 4 on the fully automatic loading and unloading mechanism 2 is linked with the rotary drive component 32 through the alignment and locking component 31. The rotary drive component 32 drives the alignment and locking component 31 to rotate while driving the reciprocating vertical movement component 33 to rotate. The rotation of the alignment and locking component 31 drives the gear 4 to rotate and heat the outer side inside the heating and quenching component 34 through the fully automatic loading and unloading mechanism 2. At the same time, the reciprocating vertical movement component 33 drives the heating and quenching component 34 to move vertically upward to spray and cool the tooth surface area of ​​the gear 4 that has been heated, thus shortening the quenching and cooling time. After quenching, the fully automatic loading and unloading mechanism 2 drives the gear 4 to rotate and enter the unloading station for unloading. At the same time, the fully automatic loading and unloading mechanism 2 rotates the next gear 4 to be quenched into the heating and quenching component 34.

The first support frame 324 is located at the front end of the indexing plate 1. The second rotating shaft 321 is rotatably connected to the rear end of the first support frame 324. A cross groove 314 is provided at the upper end of the second rotating shaft 321. The lower end of the second rotating shaft 321 is fixedly connected to the drive end of the first drive motor 323, and the first drive motor 323 is fixedly connected to the first support frame 324. The second rotating shaft 321 is fixedly connected to one synchronous pulley of the first synchronous belt and synchronous pulley transmission assembly 322. The other synchronous pulley of the first synchronous belt and synchronous pulley transmission assembly 322 is connected to the reciprocating vertical movement assembly 33. The reciprocating vertical movement assembly 33 includes a third rotating shaft 331, a second limiting rod 332, a vertical movement block 333, and a reciprocating lead screw 334. The third rotating shaft 331 is rotatably connected to the front end of the first support frame 324, and the upper end of the third rotating shaft 331 is fixedly connected to the reciprocating lead screw 334. The third rotating shaft 331 is fixedly connected to another synchronous pulley of the first synchronous belt and synchronous pulley transmission assembly 322. The two second limiting rods 332 are symmetrically distributed at the left and right ends of the third rotating shaft 331. The lower end of the second limiting rod 332 is fixedly connected to the first support frame 324. The vertical movement block 333 is slidably connected to the second limiting rod 332, and the inner wall of the vertical movement block 333 is slidably connected to the threaded groove of the reciprocating lead screw 334 through a rotatably connected slider. The synchronous pulley that is fixedly connected to the first synchronous belt and synchronous pulley transmission assembly 322 and the second rotating shaft 321 is smaller than the synchronous pulley that is fixedly connected to the first synchronous belt and synchronous pulley transmission assembly 322 and the third rotating shaft 331.

[0017] The heating and quenching assembly 34 includes a high-frequency heating coil 341, a cooling coil 342, and nozzles 343. The high-frequency heating coil 341 is fixedly connected to the rear side of the vertical moving block 333. The cooling coil 342 is located below the high-frequency heating coil 341 and is fixedly connected to the vertical moving block 333. Multiple nozzles 343 arranged in a circumferential array are fixedly installed on the cooling coil 342.

[0018] In this invention, after the operator starts the equipment, the fully automatic loading and unloading mechanism 2 drives the gear 4 into the loading station. Then, the fully automatic loading and unloading mechanism 2 fixes the gear 4 internally and rotates it to the processing station. Then, the first drive motor 323 drives the second rotating shaft 321 to rotate slowly until the cross block 313 is aligned with the cross slot 314. Then, under the drive of the alignment spring 312, it moves downward and inserts into the cross slot 314. During this process, the limiting slider 311 limits the cross block 313. Then, the first drive motor 323 drives the gear 4 to rotate through the second rotating shaft 321, the cross slot 314, the cross block 313 and the fully automatic loading and unloading mechanism 2. At the same time, the first synchronous belt and synchronous belt pulley transmission assembly 322, the reciprocating screw 334 and the third rotating shaft 331 drive the vertical moving block 3. Under the limit of the second limit rod 332, the gear 4 moves slowly upward. The high-frequency heating coil 341 first heats the gear 4 at high frequency. After heating, the nozzle 343 sprays water or cooling oil on the heated part of the gear 4 to cool it. This allows the thicker gear to be heat-treated under one drive and cooled rapidly at the same time. This avoids the heating time being too long, which would cause the tooth surface of the gear 4 to cool naturally when the upper gear 4 is heated, thus affecting the quality of the gear. After the gear 4 is heat-treated, the fully automatic loading and unloading mechanism 2 drives the heat-treated gear 4 to enter the unloading station for unloading. At the same time, the first drive motor 323 drives the vertical moving block 333 to move slowly downward and reset under the limit of the second limit rod 332 through the first synchronous belt and synchronous belt pulley transmission assembly 322, the reciprocating screw 334 and the third rotating shaft 331.

Then, the first push cylinder 227 at the loading station drives the first rotating shaft 226 to slide axially with the first sleeve shaft 225, and the first hinge rod 221 and the second hinge rod 222... With the cooperation of multiple inner support fixing plates 223, the gear 4 is fixed in place. At the same time, the first push cylinder 227 on the unloading station resets and cancels the fixing of the gear 4 by the inner support fixing plates 223. Meanwhile, the gear 4 on the heat treatment station is heat treated and cooled by the high-frequency heating coil 341, cooling coil 342 and nozzle 343.
