Description

Technical Field

[0001] This invention relates to a high-precision gear processing equipment and process, belonging to the field of gear manufacturing technology. Background Technology

[0002] Gears are mechanical components that transmit motion and power through the continuous meshing of their teeth. Their core function is to efficiently and accurately convert speed into torque. As a core component of modern mechanical transmission systems, gears transmit power through inter-tooth meshing and are widely used in various mechanical fields. Some high-end equipment places stringent requirements on transmission smoothness, positioning accuracy, and noise control. The corresponding gears must meet extremely high standards of dimensional accuracy, motion accuracy, and contact accuracy; these gears are called high-precision gears.

[0003] Currently, the mainstream high-precision gear machining adopts gear hobbing technology, and the specific process is as follows: First, the gear semi-finished product is clamped and fixed. Then, multiple cutting grooves are machined on the end face of the semi-finished product in one go by a rotating gear hobbing cutter. At the same time, the semi-finished product is driven to rotate at a preset speed, so that the machining position of the gear hobbing cutter and the semi-finished product changes synchronously. The cutter at the rear of the gear hobbing cutter will perform deep cutting on the cutting grooves that have been machined in the path, so that they are machined into tooth grooves that meet the dimensional requirements. At the same time, the cutter at the front of the gear hobbing cutter will re-machine new cutting grooves on the semi-finished product. Repeat the above tooth groove machining steps to finally complete the tooth groove machining of the entire high-precision gear. However, this machining method involves multi-station simultaneous cutting. Because synchronous cutting operations are prone to damage between adjacent tooth grooves in the semi-finished gear, the probability of gear dimensional errors during steering machining is relatively high, which will affect the machining effect and gear quality.

[0012] A high-precision gear machining process includes the following steps: Step 1: Clamping. The semi-finished product to be processed is mounted on the rotating shaft and supported by a pallet. It is then secured in the keyway of the semi-finished product by a second clamping bar. The second lifting device is then activated by the control terminal, which drives the protective shell, driver, auxiliary cylinder and pressure plate to move down and insert the upper end of the rotating shaft into the auxiliary cylinder. At the same time, multiple first clamping bars are inserted into multiple slots, and the pressure plate applies downward pressure to the supported semi-finished product, thereby clamping the semi-finished product. The second step is calibration. The telescopic device is activated by the control terminal, which moves the first lifter, the movable plate and the cutter forward and makes the cutter contact the rear end of the clamped semi-finished product, thereby completing the calibration of the initial position of the cutter. The third step is single processing. The first lifting device is started using the control terminal, which causes the cutter to move up and down in a cycle. The telescopic device is used to move the cutter forward a predetermined distance. At this time, the cutter moving up and down in a cycle cuts the semi-finished product. Then, the telescopic device is used to move the cutter forward a predetermined distance to continue the deep cutting operation at the already cut position. The same steps as above are used to process a toothed groove that meets the predetermined size at the rear end of the semi-finished product. The fourth step is the repositioning process. After the previous tooth groove is machined, the telescopic device is used to return the cutter to its original position. Then, the driver is started using the control terminal, which drives the auxiliary cylinder, pressure plate, rotating shaft, and support plate to rotate. With the assistance of the second clamping bar, the clamped semi-finished product is rotated by a predetermined angle. Then, the third step is repeated, and the above steps are repeated to machine tooth grooves of the predetermined size and number on the annular end of the semi-finished product, thereby completing the high-precision machining of the gear.

[0013] The beneficial effects of this invention are: Using a third electric push rod, the cutter is driven to move up and down in a cyclic motion. A second electric push rod and a movable plate move the cutter forward a predetermined distance, allowing for continuous forward and cyclical movement. This cutter cuts an independent tooth groove of predetermined dimensions on the rear end of the semi-finished product. Then, using a servo motor, auxiliary cylinder, and pressure plate, the clamped semi-finished product rotates by a predetermined angle, causing the cutter to again move forward and cyclically up and down, cutting another independent tooth groove of predetermined dimensions on the rear end of the semi-finished product. This process is repeated until a predetermined number and dimensions of tooth grooves are cut on the annular end of the semi-finished product, completing the high-precision gear machining. This independent, continuous cutting method effectively reduces the probability of damage to gear edges caused by multi-position synchronous hobbing, and also reduces the probability of dimensional errors in gears during steering, ensuring both machining quality and gear performance.

The fixing part of the second lifter is installed on the upper end of the outer shell 3, and the movable part of the second lifter passes through the outer shell 3 and is connected to the upper end of the protective shell 42. The second lifter drives the protective shell 42 to move up and down. The second lifter can be a first electric push rod 4. Multiple round rods 41 extending from the upper side of the outer shell 3 are evenly arranged on the upper end of the protective shell 42. The round rods 41 located outside the second lifter are slidably connected to the outer shell 3. The four round rods 41 work together to guide the up and down movement of the protective shell 42. Multiple slots 63 are formed inwardly on the annular end face of the rotating shaft 6, located on the upper side of the second locking strip 62. The slots 63 extend to the upper end of the rotating shaft 6. Through the slots 63, the working space of the first locking strip 46 is provided. Multiple first locking strips 46 are installed equidistantly on the inner wall of the auxiliary cylinder 44. The multiple first locking strips 46 are slidably connected to the upper end of the multiple slots 63, and the lower end of the multiple first locking strips 46 extends into the multiple slots 63. The multiple first locking strips 46 and the multiple slots 63 work together to restrict the installation between the auxiliary cylinder 44 and the rotating shaft 6.

[0018] The movable plate 52 is slidably connected to the inside of the rear side of the outer shell 3. The movable plate 52 provides a mounting carrier for components such as guide rods 51. The fixed part of the telescopic device is installed on the rear end of the outer shell 3, and the movable part of the telescopic device passes through the outer shell 3 and is connected to the rear end of the movable plate 52. The telescopic device drives the movable plate 52 to move back and forth. The telescopic device can be a second electric push rod 5. Multiple guide rods 51 located on the outside of the telescopic device are set on the rear end of the movable plate 52. Multiple guide rods 51 extend out of the rear side of the outer shell 3 and are slidably connected to the outer shell 3. Multiple guide rods 51 work together to guide the movement of the movable plate 52. The fixed part of the first lifter is installed on the middle of the upper end of the movable plate 52, and the movable part of the first lifter passes through the movable plate 52. The first lifter drives the cutter 8 to move up and down in a circular motion. The first lifter can be a third electric push rod 7. The cutter 8 is set on the lower end of the movable part of the first lifter. The cutter 8 cuts the semi-finished product. A groove 11 is formed by recessing the upper surface of the base cabinet 1 downwards. The groove 11 extends to the top of the inside of the base cabinet 1. The groove 11 provides a guide channel for the rectangular rod 81 to move back and forth. The rectangular rod 81 with its lower end passing through the groove 11 is installed on the lower end of the cutter 8. The rectangular rod 81 is slidably connected to the groove 11. The rectangular rod 81 drives the moving plate 82 to move back and forth. The movable plate 82 located at the upper end of the slide groove 11 is slidably connected to the outer end of the rectangular rod 81, and the movable plate 82 is slidably connected to the upper end of the base cabinet 1. The movable plate 82 provides a mounting carrier for the rack 86, and the rack 86 is set on the left end of the movable plate 82. The ring gear 94 is rotated through the rack 86, and the mounting shaft 95 is rotated and mounted on the upper end of the base cabinet 1. The mounting shaft 95 provides a mounting carrier for components such as the polishing wheel 9. The polishing wheel 9, located on the left rear side of the pressure plate 45, is placed on the upper end of the mounting shaft 95. The polishing wheel 9 is used to deburr the lower end of the machined tooth groove. The ring gear 94 is installed on the ring end of the mounting shaft 95, and the left end of the rack 86 meshes with the right end of the ring gear 94. The mounting shaft 95 is rotated by the ring gear 94. The control terminal 2, located on the right end of the outer casing 3, is installed on the upper end of the base cabinet 1. The control terminal 2 is electrically connected to the telescopic device, the first lifter, the second lifter, and the driver. The telescopic device and other components are controlled to work through the control terminal 2.

[0019] When in use, first open the door on the outer shell 3, then place the semi-finished product on the upper end of the tray 61, and let the upper end of the rotating shaft 6 pass through the semi-finished product. At this time, the second locking strip 62 is engaged in the keyway inside the semi-finished product, thereby limiting the installation between the rotating shaft 6 and the semi-finished product. Then, start the first electric push rod 4, thereby driving the protective shell 42, servo motor 43 and auxiliary cylinder 44 and other components to move down, thereby inserting the upper end of the rotating shaft 6 into the auxiliary cylinder 44, and causing multiple first locking strips 46 to be inserted into multiple locking slots 63 respectively, thereby limiting the installation between the auxiliary cylinder 44 and the rotating shaft 6. Then, the downward-moving pressure plate 45 contacts the upper end face of the semi-finished product and applies downward pressure, thereby using the pressure plate 45 and the support plate 61 to clamp the semi-finished product, realizing the pressing clamping of the semi-finished product, effectively reducing the probability of warping during cutting, effectively reducing the probability of errors in the dimensions of the processed gear, and effectively ensuring the processing effect and gear quality. At this time, the upper end face of the front part of the polishing wheel 9 contacts the lower end face of the semi-finished product.

[0020] Then, the second electric push rod 5 is activated, which drives the movable plate 52 and the cutter 8 to move forward, so that the front end of the cutter 8 contacts the rear end of the semi-finished product. The zeroing operation is then performed on the control terminal 2 to complete the calibration process. Then, the third electric push rod 7 is activated, which drives the cutter 8 to move up and down in a cyclical motion. Then, the second electric push rod 5 is used to move the movable plate 52 and the cutter 8 forward a predetermined distance. At this time, the downward-moving cutter 8 will cut the rear end of the semi-finished product. After the cutting is completed, the cutter 8 returns to its original position. The second electric push rod 5 is used again to move the movable plate 52 and the cutter 8 forward a predetermined distance again. Then, the third electric push rod 7 will drive the cutter 8 to continue to move down, and then continue to cut at the already cut position on the rear end of the semi-finished product. The same steps are repeated to make the cutter 8 continuously move forward and move up and down in a cyclical motion. After the cutter 8 moves forward to the appropriate position, it will cut an independent tooth groove of a predetermined size on the rear end of the semi-finished product. Then, using the second electric push rod 5, the movable plate 52 and the cutter 8 are returned to their original positions. Then, the servo motor 43 is started, which drives the auxiliary cylinder 44 and the pressure plate 45 to rotate. With the assistance of multiple first clamping bars 46 and multiple clamping slots 63, the rotating shaft 6, the second clamping bar 62 and the support plate 61 are rotated, so that the clamped semi-finished product rotates by a predetermined angle. Then, using the second electric push rod 5 and the third electric push rod 7, the cutter 8 is moved forward and moves up and down in a continuous cycle, so that another independent tooth groove of the predetermined size is cut on the rear end of the semi-finished product. Following the above steps, tooth grooves of the predetermined size and number are cut on the annular end of the semi-finished product, thereby completing the processing of high-precision gears. This method enables gear machining using an independent continuous cutting technique, effectively reducing the probability of damage to gear edges caused by multi-position synchronous hobbing and minimizing the probability of gear dimensional errors during steering machining, thus ensuring machining results and gear quality.

[0021] During the process of the cutter 8 returning to its original position, the rectangular rod 81 will move backward, which in turn will cause the moving plate 82 to move backward, thereby causing the rack 86 to move backward. Since the rack 86 meshes with the ring gear 94, the backward movement of the rack 86 will cause the ring gear 94 to rotate, which in turn will cause the mounting shaft 95 and the polishing wheel 9 to rotate. The rotating polishing wheel 9 will grind the lower end of the machined tooth groove in the semi-finished product, thereby achieving timely deburring of the lower end of the machined tooth groove. It also achieves linkage between cutting and deburring, effectively reducing the probability of gear size errors caused by the separate operation of cutting and deburring, improving work efficiency, and effectively ensuring processing effect and gear quality.

[0022] Example 2: Figure 3 , Figure 5 , Figure 6 , Figure 10 and Figure 11 As shown, the hollow rod 93 located behind the polishing wheel 9 is installed on the upper end of the base cabinet 1. The hollow rod 93 provides a mounting carrier for the function box 91, and the function box 91 is connected and set on the upper end of the hollow rod 93. The function box 91 provides a mounting carrier for the bristles 92. Then, multiple bristles 92 located in front of the hollow rod 93 are evenly installed on the lower end of the function box 91, and multiple bristles 92 are all attached to the upper rear end of the polishing wheel 9. The multiple bristles 92 work together to clean the upper surface of the polishing wheel 9. Multiple drainage holes are formed in the lower end of the functional box 91, located on the outer side of the brush bristles 92 and the outer side of the hollow rod 93. The drainage holes extend to the bottom of the interior of the functional box 91. The multiple drainage holes work together to deliver cleaning fluid outward. Multiple guide grooves 96 are formed in the upper end of the polishing wheel 9, extending to the annular end of the polishing wheel 9. The multiple guide grooves 96 are arranged in a circular structure, and the bottom of the guide grooves 96 is an inclined surface with the inner side higher than the outer side. The multiple guide grooves 96 work together to discharge waste liquid outward.

[0023] The piston 83 is slidably connected inside the functional cylinder 84, and the upper end of the piston 83 is connected to the lower end of the rectangular rod 81. Through the piston 83, a negative pressure is formed inside the functional cylinder 84. Two auxiliary plates 87 located on the left and right sides of the slide groove 11 are symmetrically arranged on the upper end of the functional cylinder 84, and both auxiliary plates 87 are slidably connected to the top of the cabinet 1. The two auxiliary plates 87 work together to make the functional cylinder 84 and the top of the cabinet 1 slide together. A first pipe 85 equipped with a one-way valve is connected and installed on the lower right end of the functional cylinder 84, and the other end of the first pipe 85 is connected to a storage tank 12. The functional cylinder 84 and the storage tank 12 are connected through the first pipe 85. The storage tank 12 is installed on the bottom of the cabinet 1. The storage tank 12 is used to store cleaning fluid. A second pipe 97 equipped with a one-way valve is connected and installed on the lower left end of the functional cylinder 84, and the other end of the second pipe 97 is connected to the lower end of the hollow rod 93. The functional cylinder 84 and the hollow rod 93 are connected through the second pipe 97.

[0024] In use, the second clip 62 is clipped into the keyway inside the semi-finished product, thereby limiting the installation between the rotating shaft 6 and the semi-finished product. Then, the first electric push rod 4, the rotating shaft 6, the auxiliary cylinder 44, multiple first clips 46, multiple slots 63, the pressure plate 45 and the support plate 61 are used to clamp the semi-finished product. Then, the second electric push rod 5 is used to make the front end of the cutter 8 contact the rear end of the semi-finished product to complete the calibration process. Then, by using servo motor 43, third electric push rod 7, second electric push rod 5, movable plate 52 and cutter 8, the cutter 8 is continuously moved forward and circulated up and down, and the clamped semi-finished product is rotated by a predetermined angle, thereby cutting tooth grooves of a predetermined size and a predetermined number on the annular end of the semi-finished product, thus completing the processing of high-precision gears.

[0025] During the process of the cutter 8 returning to its original position, the rectangular rod 81, the moving plate 82, the rack 86, the ring gear 94, the mounting shaft 95, and the polishing wheel 9 are used to deburr the lower end of the machined tooth groove in time. At this time, multiple bristles 92 attached to the upper end of the polishing wheel 9 will clean the upper surface of the polishing wheel 9 and push the cleaned waste into the guide groove 96. During the up-and-down movement of the rectangular rod 81, the upward movement of the rectangular rod 81 causes the piston 83 to move upward along the functional cylinder 84, thereby creating a negative pressure in the space below the piston 83 in the functional cylinder 84. Under the action of the negative pressure, the cleaning fluid stored in the storage tank 12 enters the functional cylinder 84 along the first pipe 85. During the downward movement of the rectangular rod 81, the piston 83 moves downward, thereby forcing the cleaning fluid in the functional cylinder 84 to enter the functional box 91 along the second pipe 97 and the hollow rod 93, and then discharge it to the upper end of the polishing wheel 9 through the drain hole, thereby eliminating the static electricity generated on the upper end of the polishing wheel 9 due to grinding. This allows for timely cleaning of the upper end of the polishing wheel 9, effectively reducing the probability of damage to the lower end surface of the product caused by attached debris and other factors. It effectively ensures the gear processing effect and quality, and achieves coordinated operation between cutting and cleaning, effectively reducing equipment costs and ensuring timely cleaning.

[0026] A high-precision gear machining process includes the following steps: Step 1: Clamping. The semi-finished product to be processed is mounted on the rotating shaft 6 and supported by the pallet 61. It is then secured in the keyway of the semi-finished product by the second clip 62. The control terminal 2 is then used to start the first electric push rod 4, which drives the protective shell 42, servo motor 43, auxiliary cylinder 44 and pressure plate 45 to move down. The upper end of the rotating shaft 6 is inserted into the auxiliary cylinder 44, and multiple first clips 46 are inserted into multiple slots 63. The pressure plate 45 applies downward pressure to the supported semi-finished product, thereby clamping the semi-finished product. The second step is calibration. The second electric push rod 5 is activated by the control terminal 2, which causes the third electric push rod 7, the movable plate 52 and the cutter 8 to move forward and make the cutter 8 contact the rear end of the clamped semi-finished product, thereby completing the calibration of the initial position of the cutter 8. The third step, single processing, uses the control terminal 2 to start the third electric push rod 7, so that the cutter 8 moves up and down in a cycle, and uses the second electric push rod 5 to move the cutter 8 forward a predetermined distance. At this time, the cutter 8, which moves up and down in a cycle, cuts the semi-finished product. Then, the second electric push rod 5 makes the cutter 8 move forward a predetermined distance, so as to continue the deep cutting operation at the already cut position. The same as the above steps are used to process a toothed groove that meets the predetermined size at the rear end of the semi-finished product. The fourth step is repositioning. After the previous tooth groove is processed, the second electric push rod 5 is used to return the cutter 8 to its original position. Then, the servo motor 43 is started by the control terminal 2, which drives the auxiliary cylinder 44, pressure plate 45, rotating shaft 6 and support plate 61 to rotate. With the assistance of the second clamping strip 62, the clamped semi-finished product is rotated by a predetermined angle. Then, the third step is repeated, and the above steps are repeated to process tooth grooves of the predetermined size and number on the annular end of the semi-finished product, thereby completing the high-precision machining of the gear.
