Description

Technical Field

[0001] The invention relates to the field of precision machining, and in particular to a transmission gear machining device. Background Art

[0002] The transmission is a key component in the bicycle transmission system, and the difference in its quality directly affects the overall performance of the bicycle. The transmission system is generally composed of a flywheel and a chain. The flywheel is composed of multiple gear plates of different sizes assembled in sequence.

[0003] The existing flywheel gear disc is generally made of aluminum alloy, which is moderately priced, lightweight and durable, not only reducing the overall weight of the bicycle, but also ensuring sufficient strength and wear resistance. In addition, aluminum alloy materials are easy to find in the market, and maintenance and replacement are relatively convenient.

[0004] The flywheel gear plate process includes blank warehousing inspection, rough turning, drilling, fine turning, heating and pressing, drilling and reaming, chamfering and tapping, dynamic balancing verification, factory mark engraving, cleaning, final inspection, oil seal packaging and warehousing.

[0042] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0043] The present invention provides a transmission gear processing device, such as Figure 2-5 As shown, including:

[0044] A frame 1, wherein a control system is arranged inside the frame 1, a stepped table is arranged on the top surface of the frame 1, a chain plate conveyor belt 2 and a lifting mechanism 4 are arranged on the stepped table, a plurality of equidistantly arranged die seats 3 are arranged on the chain plate conveyor belt 2, and the die seats 3 are used to place gears;

[0045] A driving mechanism 5, which is detachably mounted on the lifting mechanism 4;

[0046] The annular knife 6 is connected to the driving mechanism 5 in a transmission manner. A plurality of evenly arranged knives 63 are arranged at the bottom of the inner wall of the annular knife 6. The annular knife 6 follows the driving mechanism 5 and is placed on the lifting mechanism 4, and is in a vertical corresponding relationship with the chain plate conveyor belt 2.

[0047] The fixing mechanism 7 is arranged at the inner bottom end of the annular knife 6. In the initial state, the fixing mechanism 7 elastically protrudes from the bottom of the annular knife 6 to cooperate with the die base 3 to fix the gear;

[0048] The collecting box 8 is detachably mounted inside the annular cutter and is disposed between two adjacent cutters 63, and the bottom height of the collecting box 8 is higher than the blade of the cutter 63, so as to avoid the bottom of the collecting box 8 touching the gear plate and causing unnecessary damage during chamfering;

[0049] The control system is equipped with a sensor to detect the position of the gear plate to control the start and stop of the chain plate conveyor belt 2, the lifting mechanism 4, and the driving mechanism 5.

[0050] Among them, when the lifting mechanism 4 cooperates with the driving mechanism 5 to make the annular knife 6 perform downward high-speed rotation movement until the annular knife 6 completely covers the gear plate, the synchronously descending fixing mechanism 7 cooperates with the die base 3 to press down and fix the gear to perform chamfering. Automatic fixing is achieved during chamfering, and there is no need to install or disassemble the processed gear plate. In addition, the continuous feeding chamfering work is achieved in cooperation with the feeding chain plate conveyor 2, and the gear plate can be continuously chamfered, which greatly improves the work efficiency.

[0051] The high-speed rotating annular knife 6 generates centrifugal force around it, which makes the debris cut by chamfering adhere to the inner wall of the annular knife 6, and the debris follows the centrifugal force to enter the collecting box 8 for collection. The set annular knife 6 is used to completely cover the entire gear plate, and then the annular knife 6 is driven by the driving mechanism 5 to rotate at high speed for chamfering. The completely covered annular knife 6 can prevent the chamfered debris from leaking to the outside. At the same time, a collecting box 8 is added to the annular knife 6. The centrifugal force generated by the high-speed rotation of the annular knife 6 is used to make the debris cut by chamfering follow the airflow movement of the centrifugal force, so that the debris adheres to the inner wall of the annular knife 6, so that the debris follows the centrifugal force to enter the collecting box 8 for collection, thereby realizing automatic cleaning of the debris and reducing the influence of the debris on the chamfering work.

[0052] In this embodiment, if Figure 4 , Figure 5As shown, the driving mechanism 5 includes a second motor 51, a transmission shaft 52, a bearing 53, a first bevel gear 54, a second bevel gear 55 and an assembly disk 56, wherein the second motor 51 is arranged on the top surface of the movable end of the lifting mechanism 4, the transmission shaft 52 is rotatably plugged into the front end of the movable end of the lifting mechanism 4 through the bearing 53, the first bevel gear 54 is fixedly mounted on the output shaft of the second motor 51, the second bevel gear 55 is fixedly mounted on the top of the transmission shaft 52, and the first bevel gear 54 is meshed with the second bevel gear 55, and the assembly disk 56 is fixedly mounted on the bottom of the transmission shaft 52. When chamfering, the first bevel gear 54 of its output shaft is driven to rotate by the second motor 51, and then the second bevel gear 55 is driven to rotate by the first bevel gear 54, so that the transmission shaft 52 rotates synchronously under the action of the bearing 53, thereby making the annular knife 6 rotate at high speed.

[0053] In this embodiment, if Figure 6 As shown, the annular knife 6 includes an annular body 61 and a cutter 63. A plurality of grooves 62 are evenly opened at the bottom of the annular body 61 and in the inner circumferential direction of the annular body 61. A cutter 63 is connected to the inside of each groove 62 through a fixing bolt 64. When chamfering, the driving mechanism 5 is used to drive the annular knife 6 to move downward until the bottom of the annular knife 6 is completely covered by the gear plate, and a plurality of cutters 63 are in contact with the outer edge of the gear plate. Under the action of high-speed operation, the edge of the gear plate of the cutter 63 is chamfered.

[0054] In this embodiment, if Figure 8 As shown, the fixing mechanism 7 includes a slewing bearing 71, a connecting plate 72, a spring 73, a pressing plate 74 and an annular pressing ring 75, wherein the connecting plate 72 is rotatably mounted on the driving mechanism 5 through the slewing bearing 71 and is placed inside the annular knife 6, the pressing plate 74 is connected to the bottom of the connecting plate 72 through the spring 73, an annular pressing ring 75 is welded to the bottom of the pressing plate 74, and a protective pad is provided at the bottom of the annular pressing ring 75, when the fixing mechanism follows the annular knife 6 and the driving mechanism 5 to move downward continuously, the annular pressing ring 75 and the protective pad first contact the teeth. When the wheel disc continues to move downward, the protective pad is deformed and the pressure compresses the spring 73, causing the spring 73 to shrink until the annular pressure ring 75 and the protective pad retract into the annular knife 6. Under the elastic force of the spring 73 and in cooperation with the mold base 3 and the annular pressure ring 75, the gear disc is pressed down and fixed. There is no need for manual installation and disassembly, which saves time and effort. The fixing mechanism 7 is rotatably installed at the bottom end of the annular knife 6 through the slewing bearing 71. Under the rotating chamfering, the pressure plate 74, the annular pressure ring 75 and the gear disc product have an interference fit, so that the chamfering and the fixation do not affect each other.

[0055] In this embodiment, if Figure 7As shown, the collecting box 8 includes an assembly edge 81, an L-shaped plate 82, a movable plate 84 and two baffles 87. The movable plate 84 is movably mounted on one end of the two baffles 87 through a connecting shaft 85 and a torsion spring 86. The two baffles 87 cover the upper and lower surfaces of the L-shaped plate 82. The assembly edge 81 is arranged at the end of the L-shaped plate 82 for connecting and assembling with the annular knife 6. A plurality of micro holes 83 are provided on one side of the L-shaped plate 82 opposite to the movable plate 84. In the initial state, the movable plate 84 is moved under the elastic force of the torsion spring 86. One end of the annular blade 6 abuts against one side of the L-shaped plate 82, so that the L-shaped plate 82, the movable plate 84 cooperate with the two baffles 87 to form a sealed space to prevent debris from falling during cleaning. When the annular blade 6 rotates at a high speed, the inertia and the impact force of the airflow through the micropores 83 to impact the movable plate 84 make one end of the movable plate 84 separate from the L-shaped plate 82, so that the movable plate 84 and the L-shaped plate 82 form an opening, so that the debris attached to the inner wall of the annular blade 6 can smoothly enter the space and be collected following the centrifugal motion.

[0056] In this embodiment, if Fig. 9 As shown, the mold base 3 includes a fixed block 31, a support plate 32, and a module 33.

The plurality of support rollers 9 are in contact with the plate on the top and are in an upper and lower corresponding relationship with the annular knife 6. The plurality of support rollers 9 are used to effectively support the downward pressed chain conveyor belt 2 to prevent the chain conveyor belt 2 from bending downward, which not only effectively prevents damage to the chain plate, but also ensures the fixing effect of the fixing mechanism 7 on the gear plate.

[0059] In this embodiment, if Fig.12 As shown, the second motor 51 is detachably mounted on the front end of the lifting plate 45 , and the transmission shaft 52 is vertically plugged into the mounting plate 48 via a bearing 53 .
