Description

Technical Field

[0001] The invention belongs to the technical field of gear processing equipment, in particular to a circulating cooling device for a gear chamfering processing machine tool. Background Art

[0002] In the field of gear manufacturing, chamfering is an important process, which aims to reduce the noise during gear meshing, improve meshing accuracy, reduce meshing impact, and extend the service life of gears. It is also beneficial to the heat treatment and assembly of gears. Its essence is to perform small chamfering on all exposed sharp corners after the gear tooth profile is processed. The end face tooth profile rotation principle is a new gear processing principle. It is a processing method that realizes cutting and indexing by changing the speed ratio of the tool and the workpiece while the workpiece rotates during the processing. This method has the advantages of high processing efficiency, high processing accuracy, and a wide range of applications. Especially in the gear chamfering process, the end face tooth profile rotation principle can realize continuous and efficient chamfering processing, significantly improving processing efficiency and processing quality.

[0003] However, when gears are chamfered, especially in the processing of large gears, the tool is in working condition for a long time, which is easy to generate a lot of heat due to friction and wear. This will not only reduce the service life of the tool, but also have a negative impact on the quality and efficiency of the chamfering operation. Although some cooling technologies have been applied to gear chamfering, such as using an external cooling water source to directly spray the tool, these methods often have problems such as uneven cooling, waste of water resources, and limited cooling effect.

[0004] Therefore, there is an urgent need to develop a device that can continuously and effectively cool the tool, reduce the tool temperature, and extend its service life. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a circulating cooling device for a gear chamfering machine tool, which introduces a cooling medium (such as water) and sprays it directly into the contact area between the tool and the gear, thereby cooling the tool and the gear in a targeted manner and effectively reducing the temperature during the processing.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] A circulating cooling device for a gear chamfering machine tool comprises a gear hobbing assembly, a linear motion assembly, a rotating working arm and a processing table; the gear hobbing assembly is used to install a chamfering tool and perform chamfering on the gear; the linear motion assembly is used to realize linear movement of a workpiece or a tool during processing; the rotating working arm is used to rotate the processed gear; and the processing table is used to support the processed gear;

[0008] A transmission assembly and an intermittent water spray assembly are arranged in the rotating working arm; the transmission assembly is used to transmit the torque generated by the rotating working arm to the intermittent water spray assembly; the intermittent water spray assembly is used to perform high-pressure water spraying treatment on the contact position between the currently processed gear and the chamfering tool based on the torque generated by the rotating working arm;

[0009] A wastewater recovery component for recovering flushing water is arranged on the processing table; a detection module is arranged in the wastewater recovery component; the detection module is used to detect the processing quality of the processed gear; the detection module is electrically connected to the control module; the control module is used to optimize the chamfering processing parameters based on the processing quality.

[0010] The above scheme has the following beneficial effects:

[0011] 1. This solution places the gear to be processed on the processing table, drives the gear to rotate by rotating the working arm, chamfers the gear by the gear hobbing assembly, and adjusts the feed speed and grinding depth by the linear moving assembly. During the chamfering process, the torque generated by the rotating working arm drives the gap water spray assembly to work, thereby spraying water to cool the real-time contact position between the gear and the chamfering tool, effectively preventing the degradation of processing quality due to excessive temperature.

[0012] Compared with the existing cooling technology, this solution uses the gap water spray assembly to spray water to cool the real-time contact position between the gear and the chamfering tool, which can effectively reduce the temperature during the processing and reduce thermal deformation and workpiece dimensional errors caused by high temperature. This local cooling method is more efficient than traditional overall cooling and can more accurately control the temperature of the processing area.

[0013] 2. This solution helps reduce tool wear and workpiece burns through targeted water spray cooling, thereby improving processing accuracy and surface quality. At the same time, by optimizing chamfering processing parameters (such as feed speed, grinding depth, etc.), the processing effect can be further improved to meet higher quality requirements.

[0014] 3. This solution, through the setting of wastewater recycling components, enables the flushing water to be recycled and reused, reducing the waste of water resources. In addition, by accurately controlling the water spray volume and recycling and reuse, it can also reduce energy consumption and emissions, meeting environmental protection requirements.

[0015] 4. In this solution, while spraying water to cool down, the high-pressure water flow can also produce a certain impact force on the burrs appearing at the chamfered position. This impact force can effectively remove the tiny burrs caused by processing, thereby improving the surface quality and smoothness of the gear. This water pressure burr removal method is more efficient and environmentally friendly than traditional mechanical or chemical removal methods, and will not cause additional damage to the gear material.

[0016] Furthermore, the transmission assembly includes a first gear; the first gear is sleeved on the main shaft of the rotating working arm; the first gear is coaxially fixedly connected to the main shaft; the first gear is meshed with a second gear; the second gear is coaxially fixedly connected to a driven shaft; and the driven shaft is fixedly connected to the intermittent water spraying assembly.

[0017] Beneficial effects: The first gear is sleeved on the main shaft of the rotating working arm (the main shaft is used to drive the processed gear to rotate) and is coaxially fixedly connected with the main shaft, thereby ensuring the stability and accuracy of the transmission. This design enables the rotation of the rotating working arm to be accurately transmitted to the intermittent water spraying assembly, thereby achieving accurate control of the water spraying timing and water spraying position.

[0018] Furthermore, the intermittent water spraying assembly includes an inclined carrier and an inclined plate; a functional groove is also arranged in the rotating working arm; the inclined carrier is fixedly connected to the inner wall of the functional groove; the inclined surface of the inclined carrier is rotatably connected to the inclined plate; a plurality of connecting rods are arranged circumferentially on the inclined plate; the connecting rods are all rotatably connected to the inclined plate; the connecting rods are axially fixedly connected to a piston column at one end away from the inclined plate; a rotating plate is also rotatably arranged in the functional groove; a plurality of piston grooves are arranged circumferentially during the rotation; the piston grooves correspond to the piston columns one by one, and the piston columns slide in cooperation with the piston grooves; a plurality of water inlet channels and air inlet channels are arranged in the bottom part of the functional groove; the water inlet channels and the air inlet channels are arranged in the moving direction of the piston groove, and the water inlet channels and the air inlet channels are arranged in pairs; a water gun tube is connected to the bottom of the functional groove, and when any one of the piston grooves is docked with the water gun tube, the piston groove is connected to the water gun tube; a driving shaft is also included; one end of the driving shaft is fixedly connected to the axis of the rotating plate, the other end of the driving shaft passes through the axis of the inclined plate and the inclined carrier and is axially fixedly connected to the driven shaft, and the driving shaft is rotatably matched with the inclined carrier and the inclined plate.

[0019] Beneficial effects: the driven shaft drives the driving shaft to rotate, the driving shaft drives the turntable to rotate, and the rotation drives the piston column, connecting rod and swash plate to rotate synchronously. During the rotation of the turntable, the piston groove will undergo two processes (expansion and compression) in sequence. During the compression, the piston groove is in a closed state; during the expansion process, the piston groove will pass through the air inlet channel and the water inlet channel in sequence, so that the bottom of the piston groove gradually absorbs water and air, and then when the piston groove leaves the last water inlet channel or air inlet channel, the piston groove will undergo a compression process. Through the coordinated action of the piston column, connecting rod and swash plate, the piston column continuously squeezes the liquid and gas mixture in the piston groove (the pressure in the piston groove gradually increases), until the piston groove rotates to dock with the water gun tube, the pressure in the piston groove is instantly released, and the water and air are shot to the designated position through the water gun tube.

[0020] The design of the intermittent water spray assembly allows each water spray to fully utilize the pressure difference between water and air, and spray water and air together through the water gun tube to the designated location. This water spraying method not only improves the efficiency of water spraying, but also enhances the impact force of water spraying, thereby more effectively removing burrs and impurities on the gear surface.

[0021] Since the intermittent water spray assembly is driven by the main shaft, the rotation speed of the gear being processed can be precisely synchronized with the rotation speed of the turntable. This synchronization ensures that every time the water gun tube is connected to the piston groove, it can accurately correspond to the position on the gear being chamfered. This precise positioning capability not only improves processing accuracy, but also reduces unnecessary waste and energy consumption.

[0022] Furthermore, the water gun tube is located directly above the contact position between the processed gear and the chamfering tool.

[0023] Beneficial effect: The water gun tube is located directly above the contact point between the processed gear and the chamfering tool, ensuring that the cooling water can be directly sprayed onto the processing area. This direct cooling method can quickly reduce the temperature of the processing area and prevent problems such as thermal deformation, dimensional error and tool wear caused by high temperature.

[0024] Furthermore, the wastewater recovery component includes a collecting tank; the collecting tank is arranged on the top of the processing table; the bottom of the collecting tank is connected to a recovery tank; the recovery tank is connected to the water inlet pipe; a delivery pump is arranged in the recovery tank; the delivery pump is used to deliver water to the water inlet pipe and maintain the water volume in the water inlet pipe unchanged.

[0025] Beneficial effects: The wastewater recovery component can collect wastewater generated during the processing and re-transport it to the water inlet pipe through the delivery pump. This design realizes the recycling of cooling water and reduces the waste of water resources. The delivery pump in the recovery tank can maintain the water volume in the water inlet pipe unchanged, ensuring that the water gun tube can obtain a stable water flow during the water spraying process. This design helps to improve the continuity and stability of water spraying, thereby improving processing quality and efficiency.

[0026] Furthermore, a rotating groove is connected between the collecting groove and the recovery groove; a driving member and a rotating carrier are arranged in the rotating groove; the driving member is used to drive the rotating carrier to rotate, and the rotating carrier is rotationally connected to the rotating groove; a plurality of through grooves are circumferentially arranged on the rotating carrier, and when any through groove coincides with the recovery groove, the through groove is connected to the collecting groove and the recovery groove; a sieve plate is arranged in the through groove; the sieve plate is rotationally connected to the side wall of the through groove; a side channel is arranged on one side of the through groove; a burr groove for collecting burrs is also connected to the bottom of the rotating groove, and when any side channel is connected to the burr groove, the side channel is connected to the burr groove; a touch component is also arranged in the rotating carrier, and the touch component is used to touch the deflection of the sieve plate in the through groove when the side channel in any through groove is connected to the burr groove; the detection module includes a flow meter; the flow meter is arranged in the recovery groove; the flow meter is used to collect the flow passing through the sieve plate per unit time.

[0027] Beneficial effect: By arranging several through grooves circumferentially on the rotating carrier and arranging screen plates in the through grooves, preliminary filtration and screening of wastewater are achieved. This design can effectively remove solid particles (mainly burrs) in wastewater and improve the quality of recycled water.

[0028] When the side channel in the through groove is connected with the burr groove, the burrs in the wastewater are intercepted by the screen plate and discharged into the burr groove through the side channel, thereby realizing efficient separation and collection of the burrs.

[0029] The setting of the flow meter can accurately collect the flow rate passing through the sieve plate per unit time. By monitoring the flow rate, it can reflect the amount of burrs retained on the sieve plate from the side, thereby reflecting the chamfering quality of the gear.

[0030] Furthermore, the control module judges the quality of the gear chamfering processing based on the flow rate passing through per unit time; if the flow rate passing through per unit time is within a preset range, the control module judges that the quality of the gear chamfering processing is good; if the flow rate passing through per unit time is higher than the preset range, the control module will increase the feed speed during the gear chamfering processing and / or the rotation speed of the processed gear and the chamfering tool; if the flow rate passing through per unit time is lower than the preset range, the control module judges that the quality of the gear chamfering processing is poor, and reduces the feed speed during the gear chamfering processing or reduces the grinding depth or the rotation speed of the processed gear and the chamfering tool.

[0031] Beneficial effects: By real-time monitoring of the flow rate passing through per unit time and judging the processing quality of the gear chamfer based on this, precise control of the processing process can be achieved. When the flow rate is in the preset range, it indicates that the processing state is stable and the quality is good; when the flow rate deviates from the preset range, the system can respond quickly and adjust the processing parameters to maintain or improve the processing quality. That is, when the flow rate passing through per unit time is higher than the preset range, the system can increase the feed speed or speed to speed up the processing speed while ensuring the processing quality, thereby improving production efficiency. Conversely, when the flow rate is lower than the preset range, the generation of burrs can be avoided by reducing the feed speed, grinding depth or speed, which also helps to optimize the overall processing efficiency.

[0032] Furthermore, the touch component includes a plurality of first springs and a plurality of sliders; a plurality of slide grooves are also circumferentially arranged at the bottom of the rotating carrier; the slide grooves correspond to the through grooves one by one; the sliders are respectively slidably matched with the slide grooves; the first springs are respectively arranged in the slide grooves, and the first springs are used to provide elastic force for the sliders to slide out of the slide grooves; an arc groove and a curved groove are also arranged at the bottom of the rotating groove; the arc groove and the curved groove are connected to each other; when the side channel in any through groove is connected to the burr groove, one end of the arc groove and the curved groove are respectively connected to the through groove and the corresponding slide groove; contact blocks are arranged at both ends of the arc groove; the contact blocks are slidably matched with the arc groove; and a second spring is arranged in the arc groove.

[0033] Beneficial effect: when the slider has not passed through the curved groove, the slider is in its respective slide groove, and the first spring is in a compressed state; when the slider passes through the curved groove, the slider will quickly pop out and hit the contact block, and the contact block in the curved groove will transfer the force to the contact block at the other end through the second spring, so that the contact block will quickly pop out of the arc groove and lift one end of the screen plate, thereby deflecting the screen plate and throwing the burrs trapped on the screen plate into the side channel.

[0034] The connection design of the arc groove and the curved groove, as well as the sliding fit between the contact block and the arc groove, together form an efficient burr treatment mechanism. When the side channel is connected to the burr groove, the interaction between the slider and the contact block can quickly lift one end of the screen plate, causing the screen plate to deflect, thereby throwing the burrs trapped on the screen plate into the side channel. This design not only improves the efficiency of burr treatment, but also reduces the need for manual intervention and reduces operating costs.

[0035] Furthermore, a spiral channel is also provided in the collecting tank.

[0036] Beneficial effects: The unique design of the spiral channel can effectively reduce the kinetic energy of water when it enters the channel. When the water flows through the spiral channel, its flow direction changes continuously and the speed gradually slows down, thus achieving the stabilization of the water flow. This stabilized water flow helps to reduce the impact and fluctuation of the water flow, allowing the water flow to enter the channel more smoothly, thereby improving the efficiency and quality of wastewater treatment. The stable water flow can reduce the impact and wear on the screen plate, thereby extending the service life of the screen plate.

[0037] Furthermore, a third spring is arranged on the side wall of each side channel.

[0038] Beneficial effect: After the sieve plate throws the burr to the side channel, the sieve plate can quickly reset due to the reaction force generated by the impact of the third spring. This quick reset mechanism ensures that the sieve plate can work continuously and stably, and will not get stuck or stagnate in the side channel due to the throwing of the burr, thereby improving the continuity and efficiency of the entire processing process.

[0062] The detection module is electrically connected to the control module; the control module is used to optimize the chamfering processing parameters based on the processing quality. Specifically, the chamfering processing parameters include the rotation speed of the processed gear, the rotation speed of the chamfering tool, the feed speed and the grinding depth.

[0063] The control module determines the quality of the gear chamfering process based on the flow rate passing through per unit time; if the flow rate passing through per unit time is within a preset interval, the control module determines that the quality of the gear chamfering process is good; if the flow rate passing through per unit time is higher than the preset interval, the control module will increase the feed speed during the gear chamfering process and / or the rotation speed of the processed gear and the chamfering tool; if the flow rate passing through per unit time is lower than the preset interval, the control module determines that the quality of the gear chamfering process is poor, and reduces the feed speed during the gear chamfering process or reduces the grinding depth or the rotation speed of the processed gear and the chamfering tool. The control module is also electrically connected to the servo motor.

[0064] The specific implementation process is as follows:

[0065] First, the gear to be processed is placed on the base 401, the rotating working arm 3 is moved to the top of the base 401, and then the gear is clamped, and the gear is engaged with the main shaft 301 and the base 401. During the gear chamfering process, the main shaft 301 of the rotating working arm 3 drives the gear to rotate, and at the same time drives the transmission assembly to rotate the drive shaft 3058, thereby driving the rotating disk 3057, the piston column 3055 and the swash plate 3052 to rotate synchronously. Since the contact point position of the connecting rod 3054 and the swash plate 3052 moves back and forth during the rotation of the swash plate 3052, the piston column 3055 moves back and forth, thereby changing the air pressure in the piston groove 3056. When the piston groove 3056 passes through the water inlet channel 3059, the piston groove 3056 completes the water pumping process under the action of negative pressure, and when passing through the air inlet channel, the air pumping process is completed (because water is incompressible at room temperature, it is necessary to inhale some gas as a compression medium to achieve the pressure increase at the bottom of the piston groove 3056). When the piston groove 3056 passes through the water gun tube 306, the pressure in the piston groove 3056 is released instantly and sprayed onto the interface between the processed gear and the chamfering tool through the water gun, thereby removing the heat and removing the burrs generated by the chamfering. In this way, the reciprocating intermittent water jet is carried out to perform targeted cooling and deburring. The above process is not a continuous and overall cooling or deburring process in the traditional technology, but a real-time and targeted cooling and deburring process for the position currently being cut, which greatly improves the processing efficiency and processing quality.

[0066] When a wave of water flow (intermittent water flow, i.e. one wave after another, and the total amount of each wave of water flow is approximately equal) enters the collecting tank 402 with burrs and heat, it enters the through groove 406, and the burrs in the water flow are intercepted by the sieve plate 407. Due to the obstruction of the burrs, the flow rate through the sieve plate 407 will be reduced. At this time, the flow rate passing through the unit time is collected by the flow meter 409, and the control module uses this as the basis for judging the quality of the gear chamfering processing, and then adjusts the chamfering processing parameters.

[0067] Before the next wave of water flow arrives, the control module will drive the servo motor to operate, so that the rotating carrier 405 runs, and the rotating carrier 405 rotates to align the next through slot 406 with the recovery slot 408, and repeat the above process. When the through slot 406 with burrs trapped on the sieve plate 407 rotates to the burr slot 410, the slider 415 will be pushed out of the slide slot 412, hit the contact block 416, and deflect the sieve plate 407 toward the side channel 413, and then throw the burrs into the side channel 413, and the burrs enter the burr slot 410 and are collected. The cleaned sieve plate 407 is reset under the action of the third spring 419 for the next interception and detection.
