[0002] In the existing stainless steel gear processing process, traditional machine tool methods such as hobbing, gear shaping, gear milling or gear grinding are usually used to complete gear cutting. Since a large amount of metal debris is generated during high-speed cutting or grinding of gears, these debris are often scattered into the surrounding environment due to centrifugal force and cutting motion, and are difficult to collect effectively and centrally; in existing equipment, most of them use external adsorption methods, but such measures are often difficult to track high-speed flying debris, resulting in the debris still being deposited around the machine tool or entering between the tool and the transmission components, which can easily aggravate machine tool wear and even cause failures. On the other hand, traditional cooling devices will also bring some debris into the cooling pipes or pumps during circulation, which can easily cause pipe blockage and subsequent cleaning inconvenience, reduce processing efficiency and increase maintenance costs.

This process can significantly reduce the risk of metal debris contamination in the workshop environment, simplify the subsequent cleaning process, and improve the safety factor; (2) After the high-pressure airflow forms a positive pressure inside the machine cavity, the airflow discharged through the pressure relief port drives the outer air wheel to rotate, and then drives the rotating impeller disk at the bottom of the coolant pool to rotate synchronously, so that the coolant in the pool continuously circulates. Since the coolant remains in a rotating state, the iron chips will be concentrated and deposited at the outer position of the bottom of the coolant pool under the action of centrifugal force. This method prevents the iron chips from being re-absorbed into the cutting area in the pool liquid; (3) The cutting wheel of the present invention is driven by an independent drive motor to achieve high-speed rotation, and combined with the coolant and airflow purge, it can obtain good chip removal and cooling effects when processing stainless steel gears. Compared with the traditional method of simple spray cooling or compressed air chip removal, this system can significantly extend the service life of the cutting wheel, reduce the thermal deformation and processing errors of the tool caused by excessive cutting edge temperature, and reduce the risk of defects such as burns or discoloration on the cutting surface.

A window 110 is opened on the protective cover 108, and a sealing door 109 is installed on the window 110, and the sealing door 109 is used to block the window 110, wherein the air pump 107 is fixed on the protective cover 108, and the top end of the vertical axis bracket 102 is fixedly matched with the protective cover 108.

[0024] The working principle of a stainless steel gear processing system disclosed in the present invention is as follows: open the sealing door 109, insert the gear blank to be processed into the rotating positioning pin 135 (the through hole has been processed on the axis of the blank, if it is a spline hole, the corresponding rotating positioning pin 135 needs to be replaced to cooperate with it), and then start the clamping motor 128, the output shaft of the clamping motor 128 drives the clamping screw 129 to rotate, the clamping screw 129 drives the clamping arm 130 to move on the feed support frame 127, and at the same time, the clamping arm 130 drives the clamping spray column 136 to approach the gear to be processed to clamp the gear to be processed. Control the telescopic rod of the feed electric cylinder 124, the telescopic rod of the feed electric cylinder 124 drives the feed support frame 127 to move horizontally through the connecting rod 126, and the feed support frame 127 slides on the support column 123 through the feed guide slide bar 125. This step is used to control the distance between the gear to be processed and the cutting wheel 121, and drive the gear to be processed to approach or move away from the cutting wheel 121.

[0025] When cutting the gear, start the cutting wheel drive motor 120, the air pump 107 and the water pump, wherein the output shaft of the cutting wheel drive motor 120 drives the cutting wheel 121 to rotate (the cutting wheel 121 in the figure is not in proportion to the actual size, the larger the diameter of the cutting wheel 121, the smaller the curvature of the gear tooth root), and then control the feed electric cylinder 124 so that the gear to be processed slowly approaches the cutting wheel 121, and then the tooth root is cut on the blank, and then the blank is driven away from the cutting wheel 121, and then the rotating motor 134 is controlled, and the output shaft of the rotating motor 134 drives the driving gear 140 to rotate, and the driving gear 140 drives the execution gear 138 to rotate through the intermediate gear 139, and the execution gear 138 drives the rotating positioning pin 135 and the supporting table 137 to rotate, and the blank on the supporting table 137 rotates, rotates a certain angle, and then moves the blank to the cutting wheel 121 for cutting of the next tooth root, and so on to process the tooth shape on the blank.

[0026] Due to the high-speed rotation of the cutting wheel 121, the cut iron chips will be thrown out and then blocked by the chip cover 132, and fall into the cooling liquid in the coolant pool 111 through the supporting partition 115. Some of them will remain on the cutting edge of the cutting wheel 121. The air pump 107 generates a high-pressure airflow at the air outlet of the air pump 107, and then it is narrowed and ejected through the air nozzle 118 to increase the speed of the ejected airflow. The high-speed airflow will blow away some of the iron chips attached to the cutting edge of the cutting wheel 121. The blown-off iron chips will directly follow the airflow into the chip guide tube 122, and some will fall onto the chip cover 132, but will eventually be guided to the coolant under the supporting partition 115. Since the air wheel 117 is arranged on the outside of the protective cover 108, the pressure inside the protective cover 108 increases at this time (the sealing door 109 needs to be closed during processing), and the pressure is released through the pressure relief port 106. The airflow during the release process will push the air wheel 117 to rotate, and the air wheel 117 drives the input shaft of the gearbox 104 to rotate. The output shaft of the gearbox 104 drives the vertical shaft 103 to rotate through the top transmission belt 105, and the vertical shaft 103 drives the rotating impeller disk 114 to rotate through the bottom transmission belt 113. Then the rotating impeller disk 114 drives the coolant inside the coolant pool 111 to rotate, so that the iron filings that fall into the coolant follow the rotation. The rotation of the iron filings will be affected by the centrifugal force and gather at the bottom edge of the coolant pool 111 to prevent the coolant from sucking in the iron filings.
