Description

Technical Field

[0001] The invention relates to the technical field of metal processing equipment, in particular to a gear fillet milling tool. Background Art

[0002] Tooth surface processing generally uses profile milling cutters for milling. Profile milling cutters focus more on cutting tooth surfaces, while gear fillet processing generally uses fillet milling cutters or ball end milling cutters. Fillet milling cutters or ball end milling cutters focus more on the smoothness of chamfers. Therefore, tooth surface processing and gear fillet processing are usually divided into two steps. To ensure the processing accuracy of the gear, tooth surface processing and gear fillet processing are usually completed in one clamping.

[0003] With reference to a Chinese patent application number 202510165617.7, a gear fillet milling tool is disclosed. By setting multiple through holes on the mounting seat and setting a chuck, a slide rod and a hydraulic component in the mounting seat, the hydraulic component uniformly drives the slide rod to clamp the gear blank, so that multiple gears can be processed in a single clamping, saving the clamping time of the gear blank. At the same time, when processing gears of the same specification, the tooth surface processing of all gear blanks can be completed uniformly, and then the gear fillets can be processed uniformly, reducing the tool replacement time and improving the processing efficiency. After our research on the gear fillet milling tool, we found that the tool can only be used for the synchronous clamping of different models of gears with small differences in specifications. The synchronous clamping effect is not ideal for gears with large size differences, especially for the outer peripheral gear and the inner ring gear. It cannot be clamped synchronously, which is not conducive to the mixed processing of gears. To this end, we propose a gear fillet milling tool to solve the above technical problems.

The rotation of the adjustment plate 105 also drives the clamping block 106 to rotate together. During this period, the crescent groove 1011 slides along the outer wall of the lower shell 102, causing the angle between the adjustment plate 105 and the right-angle plate 104 to change, and the initial distance between the multiple clamping blocks 106 of the gear clamping part is adjusted, so that it can cope with the clamping of gears of different diameters and inner ring gears.

[0068] For further details, please refer to Figures 3 to 10 As shown:

[0069] The gear clamping part also includes a linear guide 1014, a linear slider 1015, a cylinder 1016, an air distribution hole 1017, a branch hole 1018, an inner thread hole 1019, a piston 1020, a piston rod 1021, a sealing top cover 1023, a cylinder 1024, a piston 2 1025, a connector 1034, a connector 2 1035, and a pressure regulating electric control valve 1036. The linear guides 1014 are fixedly installed on the top of the upper housing 103 at equal angles, and their number and position correspond one to one with the right-angle plate 104. The linear slider 1015 is slidably installed on the periphery of the linear guide 1014. The top of the linear slider 1015 is fixedly connected to the bottom of the horizontal section of the right-angle plate 104, and the cylinder 1016 is arranged at equal angles on the opposite surfaces of the lower shell 102 and the upper shell 103, and the position and number correspond one-to-one with the right-angle plate 104. The air distribution hole 1017 is opened in the middle of the opposite surface of the lower shell 102 and the upper shell 103, and the branch hole 1018 is arranged at equal angles on the opposite surface of the lower shell 102 and the upper shell 103. The position of the branch hole 1018 corresponds one-to-one with the cylinder 1016, and the cylinder 1016 is connected to the air distribution hole 1017 through the branch hole 1018. The inner thread hole 1017 is provided in the middle of the opposite surface of the lower shell 102 and the upper shell 103. 19 is opened in the middle position of the top of the upper shell 103, the piston 1020 is slidably installed in the upper and lower cylinders 1016, the piston rod 1021 is fixedly installed on the inner wall of the piston 1020 and is concentric with the cylinder 1016, the piston rod 1021 extends to the outside of the cylinder 1016, the end of the piston rod 1021 away from the piston 1020 is fixedly connected to the inner side of the vertical section of the right-angle plate 104, the sealing top cover 1023 is fixedly installed on the top of the cylinder 2 1022, the cylinder 1024 is fixedly installed on the top of the sealing top cover 1023, and its output rod is movably extended to In the second cylinder 1022, the second piston 1025 is fixedly installed at the bottom of the output rod of the cylinder 1024, and its outer wall is slidably connected to the inner wall of the second cylinder 1022, the first connector 1034 is fixedly installed on the top of the converging cavity 1028, the second connector 1035 is fixedly installed on the top of the inner thread hole 1019, and the pressure regulating electric control valve 1036 is fixedly installed on the side of the upper shell 103 through a bracket, the output end of the first connector 1034 and the input end of the pressure regulating electric control valve 1036 are connected through an air pipe, and the output end of the pressure regulating electric control valve 1036 and the input end of the second connector 1035 are connected through an air pipe.

[0070] Specifically, the output rod of the cylinder 1024 pushes the piston 2 1025 downward to move, and the air inside the cylinder 2 1022 is pressed into the air injection cavity 1026. At this time, the valve hole 1031 completely conducts the air injection cavity 1026, so that the air inside the air injection cavity 1026 is completely conducted into the confluence cavity 1028, and then enters the pressure regulating electric control valve 1036 through the connector 1034. At this time, the air pressure inside the pressure regulating electric control valve 1036 has not reached the set value, so the pressure regulating electric control valve 1036 is in the conducting state, so that the air entering the pressure regulating electric control valve 1036 is input into the connector 2 1035 through its output end, and then passes through the valve hole 1031. After the inner thread hole 1019 is discharged into the air distribution hole 1017, it is discharged into the interior of multiple cylinders 1016 through multiple branch holes 1018, pushing multiple pistons 1020 in the direction away from the air distribution hole 1017, and then pushing multiple piston rods 1021 and multiple right-angle plates 104 to move together. The movement of the right-angle plate 104 is guided by the sliding action of the linear guide rail 1014 and the linear slider 1015, which can be more linear and stable. At the same time, the right-angle plate 104 also drives the adjustment plate 105 and the clamping block 106 to move together, so that the multiple clamping blocks 106 move toward the periphery and clamp on the inner wall of the shaft hole of the gear, thereby clamping the gear for easy rounded corner milling.

[0071] For further details, please refer to Figure 10 As shown:

[0072] The switching portion includes a second cylinder 1022, an air injection cavity 1026, an air suction cavity 1027, a converging cavity 1028, a torsion hole 1029, and a valve stem 1030. The air injection cavity 1026 is provided at the lower portion of the inner wall of the second cylinder 1022, the air suction cavity 1027 is provided at the upper portion of the inner wall of the second cylinder 1022, the converging cavity 1028 is provided at the top of the fixing seat 101, and is communicated with the ends of the air injection cavity 1026 and the air suction cavity 1027. The torsion hole 1029 is provided at the fixing seat 101. The valve stem 1030 is rotatably mounted on the top of the valve stem 1030, and passes through the second cylinder 1022 and the middle of the suction cavity 1027. The valve stem 1030 is rotatably mounted inside the torsion hole 1029. The outer wall of the valve stem 1030 is penetrated by a valve hole 1031 and a valve hole 2 1032. The angle between the valve hole 1031 and the valve hole 2 1032 is 90 degrees. The valve hole 1031 is located inside the second cylinder 1022, and the valve hole 2 1032 is located inside the suction cavity 1027. A screw cap 1033 is fixedly mounted on the top of the valve stem 1030.

[0073] Specifically, by rotating the screw cap 1033, the valve stem 1030 is driven to rotate 90 degrees along the torsion hole 1029, causing the valve hole 1031 to cut off the inside of the gas injection cavity 1026, and the valve hole 2 1032 to completely conduct the inside of the suction cavity 1027. At this time, the output rod of the cylinder 1024 pushes the piston 2 1025 downward, which will cause a negative pressure effect in the upper half area of ​​the cylinder 2 1022, and is transmitted to the inside of the cylinder 1016 through the suction cavity 1027, the connector 1034, the pressure regulating electric control valve 1036, the connector 2 1035, the inner thread hole 1019, the gas distribution hole 1017, and the branch hole 1018, so that the piston 1020 moves toward the direction close to the gas distribution hole 1017, and the right-angle plate 104 is driven to move together through the connection of the piston rod 1021, thereby In one step, the adjusting plate 105 and the clamping block 106 are driven to move together through the right-angle plate 104, so that the multiple clamping blocks 106 are close to each other and clamped on the outer wall of the inner gear ring, which is convenient for clamping the inner gear ring. When the gear and the inner gear ring need to be clamped together, the screw cap 1033 corresponding to the clamping inner gear ring is rotated 90 degrees, so that it drives the valve stem 1030 to rotate along the inside of the torsion hole 1029. The rotation of the valve stem 1030 drives the valve hole 1031 and the valve hole 2 1032 to rotate together, so that the valve hole 1031 cuts off the inside of the injection cavity 1026. At the same time, the inside of the suction cavity 1027 is fully connected through the valve hole 2 1032. Then, in the process of the output rod of the cylinder 1024 pushing the piston 2 1025 downward, the gear and the inner gear ring can be clamped synchronously, which is convenient for clamping various types of gears.

[0074] For further details, please refer to Figure 4 As shown:

[0075] A spring 1037 is provided on the outer periphery of the piston rod 1021 , and the spring 1037 is fixedly installed between the lower shell 102 and the inner side surface of the vertical section of the right-angle plate 104 .

[0076] Specifically, when piston 1020 drives piston rod 1021 to move together with right-angle plate 104, it will cause tension or compression accumulation of spring 1037, thereby generating potential energy for resetting right-angle plate 104. Further, after the processing is completed, the pressure-regulating electric control valve 1036 is fully opened, so that the internal pressure of piston 1020 returns to normal, and the rebound force of spring 1037 is released, pushing the right-angle plate 104, adjustment plate 105, block 106, piston rod 1021 and piston 1020 to reset, so as to facilitate subsequent continued use.

[0077] This scheme is a gear fillet milling fixture. When working, it is divided into simultaneous clamping of gears and internal gear rings and mixed clamping. Specifically:

[0078] At the same time, when the gear is clamped, the output rod of the cylinder 1024 pushes the piston 2 1025 downward to move, and the air inside the cylinder 2 1022 is pressed into the air injection cavity 1026. At this time, the valve hole 1031 completely conducts the air injection cavity 1026, so that the air inside the air injection cavity 1026 is completely conducted into the confluence cavity 1028, and then enters the pressure regulating electric control valve 1036 through the connector 1034. At this time, the air pressure inside the pressure regulating electric control valve 1036 has not reached the set value, so the pressure regulating electric control valve 1036 is in the conducting state, so that the air entering the pressure regulating electric control valve 1036 is input into the connector 2 1035 through its output end, and then After being discharged into the air distribution hole 1017 through the inner thread hole 1019, the air is discharged into the interior of the multiple cylinder barrels 1016 through the multiple branch holes 1018, pushing the multiple pistons 1020 in the direction away from the air distribution hole 1017, thereby pushing the multiple piston rods 1021 and the multiple right-angle plates 104 to move together. The movement of the right-angle plate 104 is guided by the sliding action of the linear guide 1014 and the linear slider 1015, which can be more linear and stable. At the same time, the right-angle plate 104 also drives the adjustment plate 105 and the clamping block 106 to move together, so that the multiple clamping blocks 106 move toward the periphery and clamp on the inner wall of the shaft hole of the gear, thereby clamping the gear to facilitate rounded corner milling;

[0079] At the same time, when the inner gear ring is clamped, the valve stem 1030 is first driven to rotate 90 degrees along the inner side of the torsion hole 1029 by rotating the screw cap 1033, causing the valve hole 1031 to cut off the inside of the gas injection cavity 1026, while the valve hole 2 1032 completely connects the inside of the suction cavity 1027. At this time, the output rod of the cylinder 1024 pushes the piston 2 1025 downward, which will cause a negative pressure to be generated in the upper half of the inner area of ​​the cylinder 2 1022, and the gas is discharged through the suction cavity 1027, the connector 1034, The pressure-regulating electric control valve 1036, the second connector 1035, the inner thread hole 1019, the air distribution hole 1017, and the branch hole 1018 are transmitted to the interior of the cylinder 1016, causing the piston 1020 to move toward the air distribution hole 1017. The piston rod 1021 drives the right-angle plate 104 to move together, and the right-angle plate 104 further drives the adjustment plate 105 and the clamping block 106 to move together, so that the multiple clamping blocks 106 move closer to each other and clamp on the outer wall of the inner gear ring.

[0080] When the gears and the inner ring gear are clamped together, the screw cap 1033 corresponding to the clamped inner ring gear is rotated 90 degrees, so that it drives the valve stem 1030 to rotate along the inside of the torsion hole 1029. The rotation of the valve stem 1030 drives the valve hole 1031 and the valve hole 2 1032 to rotate together, so that the valve hole 1031 cuts off the inside of the air injection cavity 1026. At the same time, the inside of the air suction cavity 1027 is fully connected through the valve hole 2 1032. Then, in the process of the output rod of the cylinder 1024 pushing the piston 2 1025 downward, the gears and the inner ring gear can be clamped synchronously.

[0081] It should be noted that by loosening the locking nuts 1013 on the top of the gear clamping part, the adjustment plate 105 can be rotated along the rotational connection position of the ball bearing 108 and the rotating shaft 109. The rotation of the adjustment plate 105 also drives the clamping block 106 to rotate together. During this period, the crescent groove 1011 slides along the outer wall of the lower shell 102, causing the angle between the adjustment plate 105 and the right-angle plate 104 to change, and the initial distance between the multiple clamping blocks 106 of the gear clamping part is adjusted, so that it can cope with the clamping of gears of different diameters and inner ring gears.

[0082] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principles and spirit of the invention.
