Description

Technical Field

[0001] The utility model relates to a processing device, in particular to a helical gear processing device, belonging to the technical field of helical gear processing. Background Art

[0002] Gears are a common part often used in mechanical transmission. Among them, helical gears have strong load-bearing capacity and are durable. In practical applications, helical gears are widely used in high-speed and heavy-load situations due to their smooth transmission, low impact, vibration and noise. Helical gears require quenching during production, which can increase the hardness of the tooth surface, enhance its wear resistance and fatigue resistance, and also improve the overall strength and toughness of the workpiece.

[0003] A high-frequency quenching device for the tooth surface of a helical gear is disclosed in the Chinese patent application publication specification CN203034059U. A guide device is provided on the existing high-frequency quenching device for the tooth surface of a spur gear. When the helical gear teeth move axially along the helical gear tooth drive shaft, the helical gear tooth drive shaft drives the helical gear teeth to rotate around its axis under the action of the guide device. High-frequency quenching of the tooth surface of the helical gear is achieved when the induction coil is fixed, thereby improving production efficiency.

[0004] In actual applications, it was found that after the high-frequency quenching device for the helical gear tooth surface quenched the helical gear, the staff needed to use tools to manually remove the heated helical gear and then put it into water for cooling and quenching. This poses a safety hazard and is dangerous. At the same time, if the helical gear cannot be put into water in time after heating, it will affect the quenching effect of the helical gear.

[0029] The embodiment of the utility model provides a helical gear processing device.

[0030] Please refer to Figure 1 and Figure 2 The helical gear processing device comprises a housing assembly 1, the housing assembly 1 comprises a box body 101, four corners of the bottom surface of the box body 101 are fixedly connected with support legs 102, and the bottom surface of the box body 101 is fixedly connected with a drainage valve 103.

[0031] Please refer to Figure 2 , Figure 3 and Figure 4 A lifting mechanism 2 is provided inside the housing component 1, and the lifting mechanism 2 includes a servo motor 201 fixedly connected to the bottom surface of the housing component 1, an output end of the servo motor 201 passes through the housing component 1, and one end extending to the inside of the housing component 1 is fixedly connected to a screw rod 202, an outer surface of the screw rod 202 is threadedly connected to a slider 203, the front and back sides of the slider 203 are fixedly connected to fixing plates 204, the upper surfaces of the two fixing plates 204 are fixedly connected to fixing columns 205, and the lifting mechanism 2 also includes a top plate 206 fixedly connected to the upper ends of the two fixing columns 205.

[0032] The start-up of the servo motor 201 will drive the screw rod 202 to rotate, and the rotation of the screw rod 202 will drive the slider 203 limited by the limit assembly 4 to move in the vertical direction. The movement of the slider 203 will also drive the two fixed plates 204 and the two fixed columns 205 to move, and then the two fixed columns 205 will drive the top plate 206 and the bevel gear on the top plate 206 to move, and the bevel gear is driven to the bottom of the water inside the box 101 to complete the cooling of the bevel gear.

[0033] Please refer to Figure 3 and Figure 4The lifting mechanism 2 also includes a reinforcing cross plate 207 rotatably connected to the upper end of the bearing and the screw rod 202. The left and right ends of the reinforcing cross plate 207 are respectively fixedly connected to the surfaces of the two limit plates 402. The reserved holes at the front and rear ends of the reinforcing cross plate 207 are respectively slidably connected to the surfaces of the two fixed columns 205. A stirring paddle 208 is fixedly installed on the surface of the screw rod 202 close to the inner bottom wall of the box body 101. The stirring paddle 208 will stir the water inside the box body 101 under the drive of the screw rod 202, thereby accelerating the water flow speed inside the box body 101 and further improving the cooling effect on the bevel gear.

[0034] Preferably, a reinforcing cross plate 207 is provided to limit the upper end of the screw rod 202, so that the screw rod 202 can rotate more stably and avoid shaking of the screw rod 202 during rotation. At the same time, the reinforcing cross plate 207 can also limit the fixing column 205, so that the movement of the fixing column 205 is more stable, thereby increasing the stability of the device structure.

[0035] Please refer to Figure 5 A fixing mechanism 3 is provided on the top plate 206, and the fixing mechanism 3 includes two limiting grooves 307 opened on the top surface of the top plate 206. The middle part of the top plate 206 is rotatably connected to two bidirectional threaded rods 301 located in the limiting grooves 307 through a bearing. Both ends of the bidirectional threaded rod 301 extend to the outside of the top plate 206. The outer surface of the bidirectional threaded rod 301 is threadedly connected to two moving blocks 302 which are respectively slidably connected to the two limiting grooves 307. The upper surfaces of the two moving blocks 302 are fixedly connected with clamping plates 303. The side surfaces of the two clamping plates 303 that are away from each other are arc-shaped. The two ends of the bidirectional threaded rod 301 extending to the outside of the top plate 206 are fixedly connected with rotating rods 306.

[0036] The rotating rod 306 is used to facilitate the rotation of the bidirectional threaded rod 301. The rotation of the bidirectional threaded rod 301 will drive the two movable blocks 302 limited by the reserved grooves of the top plate 206 to move away from or towards each other, thereby causing the two movable blocks 302 to respectively drive the two clamping plates 303 to move towards each other. The reason why the side faces of the clamping plates 303 that are away from each other are set to be arc-shaped is to enable the clamping plates 303 to better fit the inner wall of the bevel gear, thereby improving the fixed clamping effect of the bevel gear.

[0037] Please refer to Figure 5 The left and right parts of the upper surface of the top plate 206 are fixedly connected with the first placement plate 304, and the side surfaces of the two clamping plates 303 away from each other are fixedly connected with the second placement plates 305. The top surfaces of the two first placement plates 304 and the two second placement plates 305 are on the same horizontal line. The first placement plates 304 and the second placement plates 305 can support the bottom surface of the helical gear to avoid the displacement of the helical gear during the fixed clamping process.

[0038] Please refer to Figure 3 and Figure 6 The left and right sides of the slider 203 are provided with a limit assembly 4 for limiting the rotation of the slider 203 along the axis direction of the screw rod 202. The limit assembly 4 includes a limit plate 402 fixedly connected to the left and right sides of the inner wall of the box body 101. The left and right sides of the slider 203 are fixedly connected to the limit rod 401. The two limit rods 401 are reserved at one end away from each other and are respectively slidably connected to the surfaces of the two limit plates 402. The matching setting of the limit rod 401 and the limit plate 402 can limit the slider 203, so that the slider 203 cannot rotate along the axis direction of the screw rod 202, and then the slider 203 will rise and fall under the rotation of the screw rod 202, and the slider 203 will also drive the limit rod 401 to slide on the limit plate 402.

[0039] Working principle: first, the device is placed under the existing gear high-frequency quenching equipment, then the box 101 is filled with water, and after the helical gear is heated by the existing gear high-frequency quenching equipment, the servo motor 201 is started. The start of the servo motor 201 will drive the screw rod 202 to rotate, and the rotation of the screw rod 202 will drive the slider 203 limited by the limit assembly 4 to move downward, and at the same time, the movement of the slider 203 will also drive the two fixed plates 204 and the two fixed columns 205 to move downward, so that the two fixed columns 205 drive the top plate 206 and The bevel gear fixedly clamped by the clamping plate 303 on the top plate 206 moves downward until the bevel gear moves into the water inside the box 101, completing the cooling of the bevel gear. Then the servo motor 201 drives the bevel gear to frequently rise and fall inside the box 101. At this time, the stirring paddle 208 will also rotate driven by the screw rod 202. The continuous rise and fall of the bevel gear inside the box 101 and the rotating stirring paddle 208 can accelerate the water flow speed inside the box 101, further improving the cooling effect of the bevel gear and improving the quenching effect.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
