Description

Gearbox shaft automatic rotary cutting machine

Technical Field

The utility model relates to the technical field of cutting devices, in particular to a gearbox shaft automatic rotating cutting and blanking machine.

Background Art

The gearbox is a mechanism used to change the speed and torque from the engine. It can fix or change the transmission ratio of the output shaft and the input shaft in stages. It is also called a transmission. The transmission is generally composed of a gearbox shaft and several speed gear sets. The gearbox shaft is mainly divided into an output shaft and an input shaft. Since the gearbox shaft needs to bear a large torque, the gearbox shaft needs to have strong toughness and high hardness, so it is generally made of quenched and tempered steel after normalizing.

When cutting the gearbox shaft, operators often use a cutting machine to cut out the gearbox shaft with the required size, so as to carry out the next step of processing on the gearbox shaft. In actual use, although the existing cutting machine has basic cutting functions, the existing cutting machine generally cuts the gearbox shaft by rotating and moving the cutting knife downward. When cutting to the bottom of the gearbox shaft, a large amount of heat is often generated due to the friction between the side of the cutting knife and the cutting surface of the gearbox shaft, which greatly reduces the life of the cutting knife and is very easy to be damaged. Therefore, it needs to be improved.

1. The utility model is provided with a gear ring, a No. 1 gear, a pneumatic cylinder, a No. 2 motor and a cutting knife. When the No. 1 motor is running, the circular shaft drives the No. 1 gear to start rotating. Due to the meshing between the gear ring and the outer surface of the No. 1 gear, the No. 1 gear drives the gear ring to rotate so that the mounting plate as a whole starts to rotate in a circle around the gearbox shaft. At this time, the operation of the pneumatic cylinder causes the moving block to move in the direction of the shaft as a whole. The operation of the No. 2 motor causes the rotating shaft to drive the cutting knife to start rotating, and finally causes the cutting knife to perform rotational cutting on the gearbox shaft.

Finally, the two clamping blocks clamp the gearbox shaft. At this time, the operation of the No. 4 motor will make the driving shaft drive the driving wheel to rotate coaxially, which makes the transmission belt start to rotate and drive the connecting block as a whole to move to the right under the limit of the limit groove, thereby realizing the function of automatic feeding.

The working principle and use process of this utility model:

First, the operator places the gearbox shaft between the two clamping blocks 20 and starts the No. 3 motor 16. The operation of the No. 3 motor 16 will cause the drive shaft 17 to drive the No. 2 gear 18 to start rotating. Due to the meshing between the No. 2 gear 18 and the tooth plate 19, the two tooth plates 19 will start to move toward each other along the inner surface of the mounting box 14 driven by the No. 2 gear 18. At the same time, the two clamping blocks 20 will gradually approach the outer surface of the gearbox shaft driven by the two tooth plates 19 respectively. Finally, the two clamping blocks 20 will clamp the gearbox shaft. At this time, the operator starts the No. 4 motor 22. The operation of the No. 4 motor 22 will cause the driving shaft 23 to drive the driving wheel 24 to start rotating, which causes the transmission belt 25 to start rotating. The connecting block 15, the mounting box 14 as a whole and the gearbox shaft will start to move toward the direction of the gear ring 3 driven by the transmission belt 25.

When the gearbox shaft moves to the right side of the cutting knife 12, the operator starts the No. 1 motor 4 and the pneumatic cylinder 8, and the operation of the No. 1 motor 4 will cause the circular shaft 5 to start driving the No. 1 gear 6 to rotate. Since the No. 1 gear 6 is meshed with the outer surface of the gear ring 3, the gear ring 3 together with the mounting plate 7 will rotate as a whole with the gearbox shaft as the axis under the limit of the support block 27, and the operation of the pneumatic cylinder 8 will cause the moving block 9 to drive the No. 2 motor 10, the rotating shaft 11 and the cutting knife 12 to start moving toward the gearbox shaft. When the cutting knife 12 contacts the outer surface of the gearbox shaft, the operator starts the No. 2 motor 10. The operation of the No. 2 motor 10 will cause the rotating shaft 11 to drive the cutting knife 12 to rotate the gearbox shaft for cutting. Finally, the cutting knife 12 will complete the circular shaft rotation cutting of the gearbox shaft under the joint action of the gear ring 3, the pneumatic cylinder 8 and the No. 2 motor 10.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
