Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a gear hobbing machine with a waste chip cleaning mechanism. Background Art

[0002] A gear is a mechanical component with gears on the wheel rim that continuously mesh to transmit motion and power. The application of gears in transmission appeared very early. With the development of production, the smooth operation of gears has received attention.

[0003] According to a publicly disclosed gear hobbing machine for gear processing (publication number: CN218745311U), in the above application, through the setting of the baffle, when the hob processes the material fixed on the surface of the support ring, the waste chips generated by the processing will fall on the surface of the base for collection under the obstruction of the baffle, and at the same time, the cleaning brush on the surface of the baffle will uniformly clean it to the inside of the collection tank for collection and unified treatment. At the same time, the baffle can slide to facilitate the addition of tooth blanks. The setting of the cleaning brush can clean the deposited waste chips in a timely and rapid manner, avoiding the accumulation of waste chips and ensuring normal production and processing.

[0004] The device can clean the waste debris on the surface of the base by pushing the brush toward the collection tank. However, the brush is likely to bring back small impurities remaining on the surface of the base during the return process, and waste debris will still accumulate, and the cleaning effect is average.

[0023] like Figures 1-4 As shown, the utility model provides a technical solution: a gear hobbing machine with a waste chip cleaning mechanism, comprising a machine body 1, a gear hobbing assembly 2 is provided on the machine body 1, a collecting box 3 is movably installed on the inner wall of the machine body 1, and the collecting box 3 can be used to collect waste chips for convenient centralized treatment, a protective cover 4 is fixedly installed on the outer wall of the machine body 1, and the protective cover 4 can block waste chips splashed during gear processing, and a cleaning mechanism 5 for cleaning waste chips is provided on the protective cover 4. By setting the cleaning mechanism 5, the surface of the machine body 1 can be cleaned and centrally treated.

[0024] The cleaning mechanism 5 includes a slide bar 51, an L bar 52, a rotating bar 53, a telescopic bar 54, a brush 55, a knob 56, a cam plate 57, a spring 58, and a return spring 59; the slide bar 51 is slidably connected to the inner wall of the protective cover 4, and the slide bar 51 passes through the protective cover 4. Pushing the knob 56 causes the slide bar 51 to slide along the inner wall of the protective cover 4 toward the collection box 3, and causes the brush 55 to slide to the top of the collection box 3. At the same time, the brush 55 can sweep the waste debris on the surface of the body 1 into the interior of the collection box 3 for collection. During the processing, the inner wall of the slide bar 51 is slidably connected with a telescopic rod 54, and the telescopic rod 54 passes through the slide bar 51, and the bottom of the telescopic rod 54 is in contact with the side wall of the cam plate 57. One end of the L rod 52 is fixedly installed on the top of the telescopic rod 54, and the other end of the L rod 52 is fixedly installed with a brush 55. The brush 55 is in contact with the outer wall of the body 1. By sliding the L rod 52 upward and stretching the return spring 59, the L rod 52 can drive the brush 55 to move upward, so that the brush 55 is separated from the outer wall of the body 1, and the brush 55 can be pulled out. The knob 56 is turned to drive the slide bar 51 toward the end away from the collection box 3, so that the brush 55 can be reset in a suspended state, which can effectively prevent the brush 55 from bringing waste chips back during the reset process. The outer wall of the telescopic rod 54 is sleeved with a reset spring 59, one end of the reset spring 59 is fixedly mounted on the outer wall of the L rod 52, and the other end of the reset spring 59 is fixedly mounted on the top of the slide bar 51. One end of the rotating rod 53 is rotatably connected to the inner wall of the slide bar 51, and the other end of the rotating rod 53 passes through the slide bar 51. A knob 56 is fixedly installed, and the rotating rod 53 is rotatably connected to the penetration point of the slide rod 51. A cam plate 57 is fixedly installed on the outer wall of the rotating rod 53. A spring 58 is fixedly installed on the outer wall of the rotating rod 53. The side of the spring 58 away from the rotating rod 53 is fixedly installed on the inner wall of the slide rod 51. The rotating rod 53 is rotated by turning the knob 56, and the rotating rod 53 drives the cam plate 57 to rotate, while compressing the spring 58. At this time, the cam plate 57 will squeeze the telescopic rod 54, so that the telescopic rod 54 drives the L rod 52 to slide upward.

[0025] The interior of the slide bar 51 is provided with a vibration mechanism 6 for improving the cleaning effect. By providing the vibration mechanism 6, the fine waste debris attached to the brush 55 can be shaken off to prevent the waste debris from adhering to the brush 55 and affecting the cleaning effect of the brush 55. The vibration mechanism 6 includes a rotating shaft 61, a spring 62, a steel ball 63, a driven gear 64, and a driving gear 65; the rotating shaft 61 is rotatably connected to the inner wall of the slide bar 51, and the rotating shaft 61 passes through the slide bar 51. One end of the rotating shaft 61 is fixedly mounted with the spring 62, the other end of the rotating shaft 61 is fixedly mounted with the driven gear 64, and the end of the spring 62 away from the rotating shaft 61 is fixedly mounted with the steel ball 63. The outer wall of the steel ball 63 fits into the upper surface of the brush 55. The rotation of the rotating shaft 61 and the spring 62 can drive the steel ball 63 to repeatedly hit the brush 55, causing the brush 55 to vibrate, thereby shaking off the small waste chips attached to the brush 55, so that the waste chips can fall down to the inside of the collection box 3. The outer wall of the rotating rod 53 is fixedly mounted with a driving gear 65, and the driving gear 65 is engaged with the driven gear 64. When the brush 55 moves to the top of the collection box 3, the rotating rod 53 is rotated back and forth by the knob 56. At the same time, the driving gear 65 and the driven gear 64 can drive the rotating shaft 61 to rotate synchronously.

[0026] The brush 55 is then pulled back to its original position by rotating the rotating rod 53 through the knob 56 so that the rotating rod 53 drives the cam plate 57 to rotate and compresses the spring 58 at the same time. At this time, the cam plate 57 squeezes the telescopic rod 54, so that the telescopic rod 54 drives the L rod 52 to slide upward and stretches the reset spring 59, so that the L rod 52 drives the brush 55 to move upward and separate the brush 55 from the outer wall of the machine body 1. At this time, the knob 56 can be pulled to drive the sliding rod 51 to move toward the end away from the collection box 3, so that the brush 55 can be reset in a suspended state, which can effectively prevent the brush 55 from bringing back the waste chips during the reset process and improve the cleaning effect.

[0027] When the brush 55 moves to the top of the collection box 3, the knob 56 is used to rotate the rotating rod 53 back and forth, so that the rotating rod 53 can drive the driving gear 65 to rotate back and forth. The reciprocating rotation of the driving gear 65 and the driven gear 64 engaged with it can drive the rotating shaft 61 to rotate back and forth synchronously. The rotation of the rotating shaft 61 and the reed 62 can drive the steel ball 63 to repeatedly hit the brush 55, causing the brush 55 to vibrate, thereby shaking off the small waste chips attached to the brush 55, so that the waste chips can fall down to the inside of the collection box 3, avoiding the waste chips adhering to the brush 55 and affecting the cleaning effect of the brush 55.

[0028] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
