Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a gear shaft machining device for the production of speed reducers. Background Technology

[0002] Gear shafts are core mechanical components that support rotating parts and rotate together to transmit motion, torque, or bending moment. They are widely used in various industrial transmission systems such as speed reducers, construction machinery, automotive transmissions, and wind power equipment. Their machining accuracy directly determines the operating efficiency, vibration noise, and overall service life of the transmission system. During the machining process of gear shafts, center hole finishing and journal grinding are key processes to ensure coaxiality accuracy, and have extremely high requirements for surface finish and geometric tolerances.

[0003] For example, a gear shaft processing device disclosed in CN116100085B, specifically relating to the field of gear shaft processing technology, includes a worktable, on one side of the top of the worktable, with a support frame fixedly installed. In this invention, by setting a cutting mechanism, the cutting disc is driven to rotate at high speed. With the high-speed rotation of the cutting disc, the cutting disc can perform stable automatic tooth processing on the tooth processing part of the gear shaft.

[0004] Existing gear shaft machining equipment typically divides the center hole grinding, journal grinding, and gear machining into multiple independent processes. The workpiece needs to be clamped and aligned multiple times between different equipment, which can easily cause datum offset and lead to excessive coaxiality error of each journal. In addition, during the machining process, the gear shaft is mostly supported only by the two ends of the center point. The unbalanced part with gears is prone to sagging and deformation due to its own weight, resulting in machining vibration and dimensional deviation.

[0005] For example, in the aforementioned prior art, the device can only complete the gear shaft tooth machining process and cannot integrate the center hole grinding and journal grinding functions. The workpiece needs to be clamped and transferred multiple times between multiple machines, which is prone to reference offset. Moreover, it can not offset the sagging deformation caused by the self-weight of the gear shaft by relying only on the positioning components at both ends to clamp and support the gear shaft.

[0017] This invention provides a gear shaft machining device for producing speed reducers. It has the following advantages: 1. When machining gear shafts, this machining device can complete the center hole grinding and gear shaft machining in one clamping by cooperating with the grinding unit and the polishing unit.

[0018] 2. When this processing device is processing the gear shaft, the gear position on the gear shaft is supported by the transmission wheel to counteract the sagging deformation caused by the weight of the workpiece.

The use of a turntable to switch parts avoids the reference deviation caused by secondary clamping. The transmission wheel supports and positions the gear shaft in conjunction with the workpiece rotation to achieve all-round processing. Finally, the nozzle and dust collection hopper work together in a closed-loop dust removal system to prevent dust accumulation from interfering with processing accuracy, effectively improving the finished product quality of the gear shaft.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Example 1: Refer to Figures 1-8A gear shaft processing device for producing speed reducers includes a processing table 49 set in a processing chamber 1. The processing chamber 1 provides a sealed installation space for internal repair, grinding and dust removal of various parts, preventing processing dust from drifting outward and avoiding dust leakage that pollutes the workshop environment. The processing table 49 divides the interior of the processing chamber 1 into upper and lower layers, with the upper layer being the processing operation area and the lower layer being the power transmission area.

The grinding unit is located in the processing chamber 1 and includes an adjustment component, a grinding transmission component, and a reduction component; The adjustment component is equipped with a grinding disc 32 for grinding the gear shaft. The adjustment component is used to adjust the axial position and radial feed of the grinding disc 32 so that the grinding disc 32 can be accurately aligned with each part of the gear shaft to be ground. It can perfectly adapt to the grinding needs of gear shafts of different lengths and shaft diameters, and ensure that the contact pressure between the grinding disc 32 and the workpiece surface is uniform and consistent, avoiding over-grinding or under-grinding. The grinding transmission assembly is used to transmit power to the grinding disc 32.

The reduction gear assembly is used to drive the gear shaft to rotate slowly when the grinding disc 32 grinds the gear shaft. When the grinding disc 32 grinds the gear shaft, the reduction gear assembly drives the gear shaft to rotate slowly and uniformly at a low speed, so that the entire circumferential surface of the gear shaft can be ground evenly, achieving full circumference grinding without dead angles, ensuring the consistency of the gear shaft surface processing and cylindricity accuracy, and solving the problem of uneven grinding in the traditional fixed grinding method. Separation chamber 44 is installed on the machining chamber 1. The separation chamber 44 is equipped with a dust removal component for removing grinding dust. The dust removal component is used to specifically remove metal grinding dust generated during the grinding and polishing process, preventing dust from accumulating in precision parts such as slide rails and transmission mechanisms, causing wear and jamming, and improving the machining environment inside the machining chamber 1.

One end of each transmission telescopic rod 34 is fixedly connected to a corresponding third transmission rod 38. A second transmission frame is fixedly installed on each third transmission chamber 37. The limiting rod is used to limit the sliding direction of the third transmission chamber 37, ensuring that the third transmission chamber 37 moves synchronously with the grinding seat 31, ensuring the stability of power transmission. The third transmission chamber 37 is used to protect the internal transmission components from dust contamination, extend the service life of the transmission components, and provide an installation reference for the second transmission frame. The third transmission rod 38 is used to transmit power to the transmission telescopic rod 34, driving the grinding disc 32 to rotate at high speed. The first belt is used to realize the power transmission between the two third transmission rods 38. The corresponding third transmission rod 38 in each third transmission chamber 37 passes through the third transmission chamber 37 and is connected to the second transmission frame by a fifth helical gear set 39. Each fifth helical gear set 39 is provided with two meshing helical gears. The two helical gears are respectively assembled on one end of the corresponding third transmission rod 38 and the second transmission frame. Two second cross transmission rods 36 are rotatably connected to the power chamber 10. Two fourth one-way bearings 48 are fixedly installed on the first cross transmission rod 9 located inside the power chamber 10. Each fourth one-way bearing 48 is connected to the corresponding second cross transmission rod 36 by a second belt. The fifth helical gear set 39 is used to convert the horizontal rotation of the second cross transmission rod 36 into the horizontal rotation of the third transmission rod 38, providing power to the grinding disc 32. The second cross transmission rod 36 is used to transmit the power of the first cross transmission rod 9 to the grinding transmission assembly, driving the grinding disc 32 to rotate at high speed. The fourth one-way bearing 48 is used to realize independent control of the grinding power. When the grinding unit is working, the grinding unit can stop running to avoid energy waste. When the grinding unit is working, the power is transmitted stably. The second belt is sleeved on the outer ring of the fourth one-way bearing 48 and the second cross transmission rod 36 to realize the power transmission between the two. In a further embodiment, the deceleration assembly includes multiple deceleration rods rotatably connected within the deceleration chamber 20. Each deceleration rod is fixedly mounted with a first deceleration gear, and each deceleration gear meshes with the others. A third one-way bearing 47 is fixedly mounted on the second transmission rod 13 and located inside the deceleration chamber 20. A second deceleration gear meshing with the corresponding first deceleration gear is fixedly mounted on the third one-way bearing 47. A second one-way bearing 18 is fixedly connected to the rotating rod 15. One of the deceleration rods passes through the deceleration chamber 20 and is connected to the second one-way bearing 18 via a third helical gear set 19. The third helical gear set 19 contains two meshing helical gears, which are respectively fixedly mounted on the second one-way bearing 18 and one end of the corresponding deceleration rod. Each reduction lever is fixedly equipped with a first reduction gear, forming a multi-stage reduction transmission chain. Through the sequential meshing of multiple pairs of gears, the power is reduced and the torque is increased, converting the high-speed power of the rotating motor 40 into low-speed, high-torque power, which drives the gear shaft to rotate slowly. The outer ring of the third one-way bearing 47 is fixed with a second reduction gear, realizing the one-way transmission of reduction power. When repair work is carried out, the power will not enter the reduction transmission chain, avoiding motion interference. The second reduction gear meshes with the first reduction gear and serves as the output gear of the reduction transmission chain. It introduces the power of the reduction system into the second transmission rod 13 to achieve speed reduction and torque increase. The second one-way bearing 18 is used to realize the one-way transmission of the reduction power, ensuring that the power is transmitted only from the rotating rod 15 to the reduction rod, driving the gear shaft to rotate and avoiding reverse power flow.

[0029] In a further embodiment, the dust removal assembly includes a fan 41 fixedly installed inside the processing chamber 1, an air pipe 42 fixedly installed on the processing table 49, a plurality of nozzles fixedly connected to the air pipe 42, and the air pipe 42 fixedly connected to the air outlet of the fan 41. The blower 41 is used to generate high-pressure airflow and negative pressure suction to blow away and suck up dust, forming a closed-loop air circulation system to ensure dust removal effect. The air pipe 42 is used to evenly distribute the high-pressure airflow generated by the blower 41 to each nozzle to achieve comprehensive dust blowing in the processing area. The separation chamber 44 is fixedly installed on the processing chamber 1. A dust collection hopper 46 is fixedly installed at the exhaust port on the top of the processing chamber 1. The dust collection hopper 46 is fixedly connected to the separation chamber 44. Several air inlets are opened inside the separation chamber 44. Several inclined baffles 45 for separating dust are fixedly installed inside the separation chamber 44. The air inlet of the fan 41 is connected to the separation chamber 44 through a return pipe 43. The separation chamber 44 serves as a cavity for dust separation and collection, providing installation space for the dust removal components. This allows the dust-laden air to settle and separate sufficiently within the separation chamber 44, achieving centralized collection and treatment of dust. The dust collection hopper 46 uses negative pressure suction to draw the dust-laden air from the processing chamber 1 into the separation chamber 44, achieving centralized dust extraction. The return pipe 43 is used to send the purified air back to the fan 41 for recycling. Inclined baffles 45 are arranged at an angle inside the separation chamber 44. The air outlet of the separation chamber 44 is located above the inclined baffles 45. When the dust-laden airflow passes through the inclined baffles 45 and goes to the air outlet, it impacts the surface of the inclined baffles 45, and the airflow is dispersed. The inclined baffles 45 intercept the dust and prevent the dust from being discharged upward with the airflow. The air-dust separation is achieved by impact and obstruction. The dust is retained and accumulated inside the separation chamber 44. The clean airflow flows out from the upper air outlet, which improves the dust interception effect and reduces the dust backflow into the fan 41.

[0030] The specific working principle of this processing device is as follows: The operator sends a clamping command through the control panel. The PLC controller controls the two first electric push rods 3 to extend synchronously, driving the support frame 4 to rise to the preset height. The operator places the gear shaft to be processed smoothly on the support frame 4 through the material port at the top. The support frame 4 supports both ends of the gear shaft to prevent the workpiece from tilting and falling. The flip motor 24 starts, driving the turntable 22 to rotate to the ejector pin position, so that the connecting block 27 with the ejector pin is aligned with the connecting rod 26; the first electric hydraulic cylinder 25 drives the connecting rod 26 to move towards the connecting block 27, the connecting rod 26 is inserted into the insertion hole of the connecting block 27, the locking rod and the locking hole are automatically inserted and locked to achieve circumferential fixation, the first electric hydraulic cylinder 25 continues to extend, the ejector pin presses against the center holes at both ends of the gear shaft to adjust and position the gear shaft; Based on the gear position of the gear shaft, the second electric push rod 50 pushes the first transmission frame, causing the adjusting block 6 to slide horizontally along the adjusting groove 5, which in turn moves the transmission wheel 8 to below the unbalanced gear part of the gear shaft. While the transmission wheel 8 meshes with the gear, it lifts the gear shaft to counteract the sagging deformation caused by the weight of the workpiece. After the adjustment is completed, the first electric push rod 3 drives the support frame 4 to descend and reset, avoiding interference with subsequent processing. The first electric hydraulic cylinder 25 drives the connecting rod 26 to retract, causing the connecting block 27 with the ejector pin to be positioned on the turntable 22. At this time, the electromagnetic block 23 is energized to attract the armature 28, fixing the connecting block 27 with the ejector pin on the turntable 22. At this time, the flipping motor 24 starts again, driving the turntable 22 to rotate at a set angle and switch to the grinding head position, so that the connecting block 27 with the grinding head is aligned with the connecting rod 26. After the turntable 22 rotates to the position, the first electric hydraulic cylinder 25 extends again, and the connecting rod 26 and the connecting block 27 of the grinding head are inserted and locked. When the rotating motor 40 starts, it drives the first cross transmission rod 9 to rotate at high speed. The first cross transmission rod 9 drives the rotating rod 15 to rotate synchronously through the cross groove. At this time, the first one-way bearing 16 is locked, and the second one-way bearing 18, the third one-way bearing 47 and the fourth one-way bearing 48 are all in an idle state. The power is transmitted to the second helical gear set 17 through the first one-way bearing 16. The second helical gear set 17 converts the horizontal rotation of the rotating rod 15 into the vertical rotation of the second transmission rod 13. The second transmission rod 13 then transmits the power to the first transmission rod 12 through the first helical gear set 14. The first transmission rod 12 drives the transmission wheel 8 to rotate. The transmission wheel 8 drives the gear shaft to rotate through gear meshing. When the transmission wheel 8 drives the gear shaft to rotate through gear meshing, the first electric hydraulic cylinder 25 drives the grinding head to slowly feed into the center hole of the gear shaft. Then, in conjunction with the rotation of the gear shaft, the center hole is cut and ground to remove the oxide scale and machining allowance on the surface of the center hole, and to correct the roundness and roughness of the center hole. During the grinding process, the locking mechanism effectively resists the cutting reaction force, prevents the grinding head from deflecting, and ensures the grinding accuracy. During the research and development phase, the inner ring of the second one-way bearing 18 rotates with the rotating rod 15 but the outer ring does not rotate; the inner ring of the third one-way bearing 47 rotates with the second transmission rod 13 but the outer ring does not rotate; and the inner ring of the fourth one-way bearing 48 rotates with the first cross transmission rod 9 but the outer ring does not rotate. All three rotate freely, and the power will not enter the reduction assembly and the grinding unit, thus achieving independent power distribution and completely avoiding motion interference. After the center hole is finished, the first electric hydraulic cylinder 25 drives the grinding head to retract, the flipping motor 24 drives the turntable 22 to switch back to the ejector pin position, and the first electric hydraulic cylinder 25 drives the ejector pin to press against the upper end face of the gear shaft again to ensure stable workpiece positioning during the grinding process. The electric slide rail 29 drives the grinding seat 31 to move axially along the gear shaft, so that the grinding disc 32 is aligned with the first area to be ground. Then the second electric hydraulic cylinder 30 drives the grinding disc 32 to feed radially until the grinding disc 32 contacts the journal surface and reaches the preset grinding pressure. During the grinding process, the transmission telescopic rod 34 automatically extends and retracts with the radial feed of the grinding seat 31 to maintain the continuity of power transmission. During the polishing process, the rotating motor 40 rotates in the opposite direction, the first cross transmission rod 9 maintains high-speed rotation, at which time the fourth one-way bearing 48 is in the locked state, the first one-way bearing 16 switches to the idling state, and the states of the second one-way bearing 18 and the third one-way bearing 47 are simultaneously switched to the locked state. The fourth one-way bearing 48 drives the second cross transmission rod 36 to rotate via the second belt. The second cross transmission rod 36 transmits power to the third transmission rod 38 via the fifth helical gear set 39. The two third transmission rods 38 rotate synchronously via the first belt, driving the transmission telescopic rod 34 to rotate. The transmission telescopic rod 34 transmits power to the grinding disc 32 via the fourth helical gear set 35, driving the grinding disc 32 to rotate at high speed for grinding. The first cross-shaped transmission rod 9 drives the rotating rod 15 to rotate, and the second one-way bearing 18 locks it. The power is transmitted to the third helical gear set 19 through the second one-way bearing 18. The third helical gear set 19 converts the horizontal rotation of the rotating rod 15 into the vertical rotation of the reduction rod. Multiple reduction rods form a three-stage reduction transmission chain through the meshing first reduction gear, which reduces the high-speed power and increases the torque. The reduced power is transmitted to the outer ring of the third one-way bearing 47 through the second reduction gear. The third one-way bearing 47 locks and drives the second transmission rod 13 to rotate. The second transmission rod 13 drives the first transmission rod 12 and the transmission wheel 8 to rotate through the first helical gear set 14, which finally drives the gear shaft to rotate at a low and uniform speed, so that the grinding disc 32 can grind the gear shaft evenly. During the grinding stage, the inner ring of the first one-way bearing 16 rotates with the rotating rod 15, but the outer ring does not rotate and is in an idle state. Power will not be transmitted in reverse through the first one-way bearing 16, thus avoiding interference with the deceleration power. After one position is polished, the second electric hydraulic cylinder 30 drives the polishing disc 32 to retract, and the electric slide rail 29 drives the polishing seat 31 to move to the next position to be polished. The above polishing process is repeated until all journals are polished. Throughout the process, the second one-way bearing 18, the third one-way bearing 47, and the fourth one-way bearing 48 remain locked, and the first one-way bearing 16 remains in an idle state. During the processing, the blower 41 starts to generate high-pressure airflow, which is delivered to each nozzle through the air pipe 42. The nozzle sprays high-pressure airflow into the processing area to blow away the metal dust attached to the surface of the gear shaft, the processing table 49 and various parts. The air inlet of the blower 41 generates negative pressure suction, and the dust-laden air in the processing chamber 1 flows upward under the action of negative pressure and is sucked into the separation chamber 44 through the dust collection hopper 46 at the top of the processing chamber 1. After the dust-laden airflow enters the separation chamber 44, it impacts the inclined baffle 45, which disperses the airflow and changes its direction. Due to its large inertia, the dust loses kinetic energy after impacting the baffle 45 and settles downward under the action of gravity, remaining at the bottom of the separation chamber 44. The clean airflow bypasses the baffle 45 and flows out from the air outlet above the separation chamber 44. The purified air returns to the air inlet of the fan 41 through the return pipe 43 and is pressurized and delivered to the nozzle again, forming a closed-loop air circulation. After all processing steps are completed, the rotating motor 40 stops running, and the first one-way bearing 16, the second one-way bearing 18, the third one-way bearing 47, and the fourth one-way bearing 48 all return to a stationary state; the grinding disc 32 and the transmission wheel 8 stop rotating, the second electric hydraulic cylinder 30 drives the grinding disc 32 to return to its original position, and the electric slide rail 29 drives the grinding seat 31 to reset to its initial position. The first electric push rod 3 drives the support frame 4 to rise and lift the gear shaft, moving the gear shaft out of the material port at the top of the processing chamber 1. The operator removes the processed gear shaft, places the next workpiece to be processed, and repeats the above process for batch processing.
