Description

Technical Field

[0002] A reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine. The production and manufacturing of reducer gears generally use milling machines, gear shapers, or hobbing machines for processing. Among them, the milling machine has low processing efficiency, the gear shaper has low processing accuracy, and the hobbing machine is the most widely used gear tooth machining machine, which can cut straight teeth and helical cylindrical gears, and can also process worm wheels, sprockets, etc.

[0003] In the existing hobbing machines, the hob is installed on the hob spindle and driven by the main motor to rotate. The tool holder can move vertically along the column guide rail and can also be adjusted by an angle around the horizontal axis. The workpiece is installed on the workbench and driven by the indexing worm gear pair to rotate, which together with the movement of the hob constitutes a generating motion. The workbench (or column) can move along the bed guide rail to adapt to different workpiece diameters and perform radial feed. Currently, the existing hobbing machines usually conduct quality inspection after the gear processing is completed, which has a certain delay. It is difficult to monitor the defects in gear processing in a timely manner. It may be found that there are defects such as scratches and abrasions on the gear surface after one or more batches of gears are processed, and then the machine is stopped to repair or replace the hob. There is a certain time difference between quality inspection and production. The gears processed during this time difference need to be repaired, reworked, or even discarded, which affects the gear production progress. Summary of the Invention

A drive mechanism for driving the drive shaft 3 to rotate is installed on the bed body 1. The drive mechanism is the prior art of a hobbing machine well-known to those skilled in the art. The rotation of the drive shaft 3 is not the main innovation point of the present disclosure and will not be elaborated here. The drive shaft 3 can drive the drive seat 101 to rotate. The hob spindle 4 can be installed inside the drive seat 101 through the sliding fit between the limit block 104 and the installation groove. The electric cylinder 103 drives the limit seat 102 to approach the hob spindle 4, and the other end of the hob spindle 4 can be inserted into the limit seat 102. The hob spindle 4 is pressed against the inside of the drive seat 101 through the limit seat 102. The drive shaft 3 drives the drive seat 101, the hob spindle 4 and the limit seat 102 to rotate, so as to drive the tool 5 to perform hobbing on the gear workpiece. The electric cylinder 103 drives the limit seat 102 to move away from the hob spindle 4, so that the hob spindle 4 can slide out from the inside of the limit seat 102 and the drive seat 101, thereby the hob spindle 4 and the tool 5 can be replaced to adapt to the processing requirements of different gears, or the damaged tool 5 can be disassembled and replaced.

[0032] The cutting fluid pipe 11 is arranged on the tool rest 9. The cutting fluid pipe 11 is communicated with the cutting fluid conveying equipment. The lifting of the tool rest 9 can drive the cutting fluid pipe 11 to lift. The cutting fluid pipe 11 always faces the direction of the tool 5, so that cutting fluid can be sprayed to the cutting position to cool and lubricate the cutting position and reduce the heat deformation caused by the friction between the tool 5 and the gear workpiece.

[0033] The drying pipe 12 is installed on the pressing seat 7 and is used to blow gas to the area after the gear workpiece is cut. The camera 13 is installed on the pressing seat 7 and is used to take images of the area after the gear workpiece is cut and dried. The cutting fluid pipe 11, the drying pipe 12, and the camera 13 are arranged in sequence along the rotation direction of the gear workpiece. A mounting plate 14 is movably arranged on the pressing seat 7. Both the camera 13 and the drying pipe 12 are installed on the mounting plate 14. A sliding rod 15 is fixedly connected to the pressing seat 7, and a sliding seat 16 is fixedly connected to the mounting plate 14. The sliding rod 15 and the sliding seat 16 are in sliding fit. A locking bolt 17 for locking and fixing the sliding seat 16 is threadedly connected to the sliding seat 16. The position of the mounting plate 14 can be adjusted through the sliding fit between the sliding seat 16 and the sliding rod 15, that is, the distances between the drying pipe 12 and the camera 13 and the pressing seat 7 are adjusted, so that the drying pipe 12 and the camera 13 blow dry and photograph the tooth positions at the edge of the gear. The drying pipe 12 is communicated with an external air supply device 24. The air supply device 24 conveys gas to the drying pipe 12 and blows it to the tooth positions at the outer edge of the gear workpiece, blowing off the cutting fluid on the surface of the gear workpiece, facilitating the photographing of the gear workpiece by the camera 13, and reducing the interference of the cutting fluid on the image. The camera 13 is a high-resolution camera 13, which takes pictures of the image after the gear is processed and dried. Combining image processing algorithms to analyze defects such as burrs, cracks, and pores on the tooth surface, and timely controlling the machine tool to stop working for maintenance, reducing the generation of defective products or scrap parts. The camera 13 takes multiple local images of a single tooth surface and stitches them into a full tooth surface image through feature matching (such as SIFT / SURF). Through preprocessing algorithms such as denoising, enhancing contrast, geometric correction, and background segmentation, the details and clarity of the image are guaranteed. Defect detection is achieved through feature extraction such as edge detection, texture analysis, and spot detection, and segmentation of scratch and pit areas according to gray level differences. It can cooperate with a deep learning model to detect complex defects. The image processing algorithm is a well-known prior art to those skilled in the art and is not the main innovation point of this disclosure, so it will not be elaborated here.

[0034] To reduce the contamination of the lens of camera 13 by debris and cutting fluid, a protective glass 18 is detachably installed on the camera 13. A glass mounting frame 19 is detachably connected to the camera 13 by bolts. The protective glass 18 is installed inside the glass mounting frame 19. A cleaning member for cleaning the surface of the protective glass 18 is installed on the mounting plate 14. The cleaning member includes a rotating rod 201. The rotating rod 201 is rotatably arranged on the mounting plate 14. A cleaning motor 202 is installed on the mounting plate 14. The rotating rod 201 is fixedly connected to the output end of the cleaning motor 202. A cleaning cloth 203 for wiping the protective glass 18 is installed on the rotating rod 201. The cleaning cloth 203 is detachably connected to the rotating rod 201 by Velcro. The drying pipe 12 is communicated with a purging pipe 20 for blowing gas to the protective glass 18. The lens of the camera 13 is protected by the protective glass 18 to prevent metal debris from splashing on the lens of the camera 13 and causing damage. The cleaning motor 202 is regularly turned on, so that the cleaning motor 202 drives the rotating rod 201 and the cleaning cloth 203 to rotate during the shooting interval of the camera 13. The cleaning cloth 203 contacts the outer surface of the protective glass 18 and sweeps off the dirt and cutting fluid on its surface during rotation, avoiding interference with image shooting. When the protective glass 18 is scratched by metal debris, the protective glass 18 can be disassembled and replaced by bolts.

[0035] To reduce the contamination of the protective glass 18 by the cutting fluid sprayed by the cutting fluid pipe 11, a protective plate 21 for blocking the cutting fluid is installed on the mounting plate 14. The bottom end of the protective plate 21 is lower than the protective glass 18, which can block the splashing of the cutting fluid to a certain extent and reduce the influence of the cutting fluid on the shooting of the camera 13.

[0036] To improve the drying effect on the gear, a heating chamber 22 is further included. A heater 23 is installed inside the heating chamber 22. The heating chamber 22 is communicated with a gas supply device 24. The gas supply device 24 can be selected as a blower. The drying pipe 12 is communicated with the heating chamber 22. The heater 23 can be selected as an electric heating wire. The heater 23 is powered on to heat up. The gas supply device 24 supplies gas to the inside of the heating chamber 22. The gas is heated by the heater 23, and the hot gas is blown onto the surface of the gear through the drying pipe 12, further improving the drying effect on the cutting fluid, facilitating the quick drying of the processed gear teeth, and reducing the interference of the cutting fluid on the image shooting of the gear teeth.

[0037] The working principle or usage process of the CNC machine tool for gear tooth processing based on the production of reducer gears is as follows: Clamp the gear workpiece to be processed on the clamping seat 6, adjust the height of the pressing seat 7 to press the top of the gear workpiece, adjust the height of the tool rest 9 to correspond to the height of the gear workpiece, select a suitable tool 5, install the driving spindle between the driving seat 101 and the limiting seat 102, the driving mechanism drives the driving shaft 3 to rotate, thereby driving the hob spindle 4 and the tool 5 to rotate, the lead screw feeding mechanism drives the workbench 2 to approach the tool 5, and the clamping seat 6 drives the gear workpiece to rotate, and cooperates with the tool 5 to perform hobbing processing; During the processing, the cutting fluid pipe 11 sprays cutting fluid to the processing position. As the clamping seat 6 drives the gear workpiece to rotate, the processed tooth rotates to the drying pipe 12. The hot air is conveyed to the drying pipe 12 through the cooperation of the air supply device 24 and the heater 23, and the drying pipe 12 sprays the hot air on the gear surface to dry the cutting fluid on the surface of the processed tooth; The camera 13 takes pictures of the dried teeth, analyzes the tooth surface defects by combining the image processing algorithm. When defects appear on the gear surface, the numerical control machine tool for gear tooth processing based on the production of reducer gears is immediately controlled to stop working. If it is due to the tool 5, the electric cylinder 103 drives the limiting seat 102 to move away from the hob spindle 4, pulls out the hob spindle 4 from the driving seat 101 and replaces it, and then the electric cylinder 103 drives the limiting seat 102 to press the hob spindle 4 on the driving seat 101, and then the subsequent processing can be carried out.
