Description

Technical Field

[0001] The utility model specifically relates to the technical field of gear processing, in particular to an inverse gear tooth profile processing device for automobiles. Background Art

[0002] A reverse gear is a special gear transmission device whose main function is to change the direction of rotation. While power is transmitted through spur gears, the direction of rotation is fixed. However, the introduction of a reverse gear can make the output shaft rotate in the opposite direction of the input shaft. The working principle is to transmit power and change the direction of rotation through the meshing of gears. After production, the reverse gear tooth profile requires grinding.

[0003] However, in practice, people have noticed that there will be relatively sharp burrs on the edges of the reverse gears after production. When the burrs are located between the tooth profiles, they need to be cleaned manually, resulting in low efficiency. In addition, when manually handled, the sharp burrs can easily scratch the workers' skin, affecting the safety effect when handling the reverse gears. In addition, when using equipment to process the tooth profiles, the reverse gears need to be replaced after shutdown, which is inefficient. In addition, the current required by the motor at startup is large, and frequent startups will consume more electricity, resulting in energy waste. Utility Model Content

[0032] See also Figure 1-7 The present invention provides a reverse gear tooth profile processing device for automobiles, comprising:

[0033] A hollow frame body 1 is symmetrically provided with limiting side plates 2 on the frame body 1, a movable feed frame 4 is movably connected between the two limiting side plates 2, and a gear rotator 5 is installed on the top of the movable feed frame 4;

[0034] An inclined bracket 6 is fixedly connected to the upper portion of the frame body 1 , the side surface of the inclined bracket 6 is inclined toward the side close to the gear rotator 5 , and a gear hobbing cutter 7 is movably connected to the end portion of the inclined bracket 6 .

[0035] In this embodiment, the movable feed frame 4 includes a push rod column 41 movably connected to the limiting side plate 2, and limiting columns 42 are integrally provided on both sides of the push rod column 41. A tension spring 9 is provided on the side of the push rod column 41, and a hanging hole plate 46 corresponding to the tension spring 9 is welded on the side of the push rod column 41.

[0036] In this embodiment, the end of the tension spring 9 is inserted with a limit pin 10 , and the limit pin 10 is fixedly connected to one side of the two limit side plates 2 , and the other end of the tension spring 9 is hung with the hanging hole plate 46 .

[0037] In this embodiment, a strip-shaped tooth groove 43 and a ladder frame 45 are respectively provided on both sides of the push rod column 41, wherein a driving gear 44 engaged with the strip-shaped tooth groove 43 is provided on the side of the push rod column 41, and the tension spring 9 and the limit pin 10 are respectively located in the ladder frame 45.

[0038] In this embodiment, the limiting side plate 2 includes a support plate 21 , and a side surface of the support plate 21 is provided with two identical rail grooves 22 in a rectangular array. The ends of the rail grooves 22 are provided with through holes 23 .

[0039] In this embodiment, the two support plates 21 are symmetrically fixed on the side of the frame body 1, and the side of any one of the support plates 21 is fixedly connected to the drive motor 3, and the end of the drive motor 3 passes through the drive motor 3 and is connected to the drive gear 44 through a flat key.

[0040] In this embodiment, the two limiting side plates 2 are respectively located on both sides of the top rod column 41, and the end of the limiting column 42 is inserted into the track slide groove 22, and the limiting pin 10 is fixedly connected to the end between the two track slide grooves 22.

[0041] In this embodiment, a movable platform 47 is fixedly connected to the top of the mandrel column 41 . The movable platform 47 is located above the two support plates 21 and on the side of the inclined bracket 6 .

[0042] In this embodiment, the gear rotator 5 includes a conical positioning seat 51, and the bottom of the conical positioning seat 51 is integrally provided with a support shaft 55. The bottom of the support shaft 55 is movably connected to the movable platform 47 through a bearing, and the bearing is interference fit with the support shaft 55 and the movable platform 47 respectively.

[0043] In this embodiment, a positioning protrusion 52 is integrally provided on the side of the conical positioning seat 51 , and a locking knob 53 and a fixed top seat 54 are provided on the top of the conical positioning seat 51 .

[0044] By adopting the above technical solution, the driving motor 3 drives the driving gear 44 to rotate, and through the mutual engagement between the driving gear 44 and the bar tooth groove 43, the top rod column 41 moves upward on the inner side of the support plate 21, and the limiting column 42 slides on the inner side of the track slide groove 22. When the limiting column 42 moves to the extreme position at the top of the track slide groove 22, the tension spring 9 applies a rightward pulling force to the top rod column 41 through the hanging hole plate 46, causing the top rod column 41 to move to the right, and the limiting column 42 moves to the lower right along the inclination of the top of the track slide groove 22, and slides to the bottom along the groove on the right side of the track slide groove 22. After the top rod column 41 moves to the right, the bar tooth groove 43 and the driving gear 44 are separated from each other, and the gear can be taken without stopping the driving motor 3, reducing the starting frequency of the driving motor 3 and thus reducing energy consumption.

[0045] In this embodiment, a rotating motor 8 is fixedly connected to the side of the tilting bracket 6. The end of the rotating motor 8 passes through the tilting bracket 6 and is connected to the end of the gear hobbing cutter 7 through a coupling. The output shaft of the rotating motor 8 drives the gear hobbing cutter 7 to rotate inside the tilting bracket 6.

[0046] In this embodiment, the bottom of the fixed top seat 54 is provided with an arc-shaped pressure plate in a circular array, and the end of the locking knob 53 passes through the fixed top seat 54 and is threadedly connected to the conical positioning seat 51. The locking knob 53 is rotated, and the fixed top seat 54 is moved closer to the conical positioning seat 51 through the threaded cooperation between the locking knob 53 and the conical positioning seat 51.

[0047] In this embodiment, the rail slide 22 has two parallel vertical grooves, and the tops of the two vertical grooves are provided with inclined connecting grooves. When the driving gear 44 and the bar-shaped tooth groove 43 are engaged, the limiting column 42 slides upward in the vertical slide on the left side of the rail slide 22. When the rail slide 22 moves to the connecting groove at the top, the limiting column 42 moves from the vertical groove on the left side of the rail slide 22 to the sliding groove on the right side through the inclined connecting groove.

[0048] In this embodiment, the gear hobbing cutter 7 has a cylindrical roller and a spiral grinding block, and the cross-section of the grinding block is arranged in a tooth groove shape. After the rotating gear hobbing cutter 7 contacts the tooth profile of the gear, the sharp burrs in the tooth profile are eliminated by the friction between the contact positions.

[0049] The working principle of the present invention is as follows: when in use, first remove the locking knob 53 and the fixed top seat 54 from the top of the conical positioning seat 51, then put the reverse gear sleeve on the top of the conical positioning seat 51, and the keyway in the reverse gear is stuck on the outside of the positioning protrusion 52, then place the fixed top seat 54 on the top of the reverse gear, and then pass the end of the locking knob 53 through the fixed top seat 54 and threadedly connect it with the conical positioning seat 51 to clamp the reverse gear, and then rotate the motor 8 to drive the gear hobbing cutter 7 to rotate, and at the same time, the driving motor 3 is engaged between the strip tooth groove 43 and the driving gear 44 to mobilize the push rod column 41 to move upward, and the limit column 42 on the side of the push rod column 41 slides on the inner side of the track slot 22, so that the gear rotator 5 The reverse gear also moves upward. After the tooth profile of the reverse gear contacts the gear hobbing cutter 7, the sharp burrs in the tooth profile are eliminated by friction. When the track slide 22 moves to the connecting groove at the top, the limit column 42 is moved from the vertical groove on the left side of the track slide 22 to the sliding groove on the right side through the inclined connecting groove. Since the top rod column 41 slides to the right, the strip tooth groove 43 and the drive gear 44 are separated at this time, and the top rod column 41 slides to the bottom by its own weight, which is convenient for the staff to replace the reverse gear without stopping the machine. Then, the ladder frame 45 pushes the top rod column 41 back to the vertical groove on the left side of the track slide 22, and repeats the above steps to reduce the start and stop times of the drive motor 3, thereby reducing energy consumption.
