Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

As shown in fig. 1, fig. 2, fig. 3, a wheel hub cutting blade installation device, the main function is to cut the wheel hub of the train, and easy to assemble, the utility model discloses a cutting blade main part 1, cutting blade main part 1 is fixed on main shaft 2, drives cutting blade main part 1 by main shaft 2 and moves, and cutting blade main part 1 includes fixed part 4, aligns the hole of cutting blade main part 1 center department with fixed axle 3 on main shaft 2 when installing cutting blade main part 1 and fixes, and fixed part 4 is used for preventing cutting blade main part 1 from rocking afterwards.

In order to prevent the cutting insert body 1 from shaking and facilitate installation of the cutting insert body 1, the spindle 2 is provided with an i-shaped groove 5 corresponding to the fixing portion 4, a fixing grip 11 is arranged at the center of the fixing portion 4, the fixing grip 11 is a protrusion on the surface of the fixing portion 4, and the fixing grip 11 can be clamped in the groove 5, so that the cutting insert body 1 with the fixing grip 11 cannot shake. The fixed hand grip 11 comprises a fixed hand grip center 12 and a U-shaped hand grip 13 connected with the fixed hand grip center 12, wherein the I-shaped part is divided into two symmetrical halves which are just in a U shape, so that the hand grip is designed into the U-shaped hand grip 13 and has better fixing effect. The fixing portion 4 is further provided with right-angled triangular cylinders 14, which right-angled triangular cylinders 14 assist the fixing of the cutting insert body 1 on the spindle 2, even if the fixing portion 4 with the projections is more easily accessible in the recess 5. The right-angled triangular cylinder 14 comprises a smooth lead-in inclined surface 31, one edge of the lead-in inclined surface 31 is overlapped with the edge of the fixing part 4, the right-angled triangular cylinder 14 can directly push the cutting blade body 1 along the fixing shaft 3 when the hole of the cutting blade body 1 is sleeved with the fixing shaft 3 on the main shaft 2, and the lead-in inclined surface 31 is contacted with the edge of the main shaft 2 to enable the cutting blade to be gradually lifted, so that the convex fixing hand grip 11 can conveniently enter the groove 5.

In order to prevent the fixing hand 11 from being stuck when entering the groove 5, since the fixing shaft 3 presses the cutting blade body 1 down to be tightly attached to the main shaft 2, the convex fixing hand 11 in the cutting blade body 1 is easily stuck at the edge of the main shaft 2, the right-angled triangular cylinder 14 further comprises a right-angled surface 32, the right-angled surface 32 is perpendicular to the fixing part 4, the right-angled surface 32 and the lead-in inclined surface 31 are intersected outside the plane of the fixing part 4, the thickness of the U-shaped hand 13 is smaller than the height of the right-angled surface 32, and therefore the lead-in inclined surface 31 can guide the cutting blade body 1 and the main shaft 2 to leave enough clearance for the convex fixing hand 11 to enter.

In order to ensure that the distance between the main shaft 2 and the cutting blade body 1 is large enough when the U-shaped gripper 13 passes through, the height of the right-angle surface 32 is larger than the thickness of the U-shaped gripper 13, and the right-angle surface 32 and the two ends of the U-shaped gripper 13 are on the same straight line, so that the distance between the main shaft 2 and the cutting blade body 1 is the height of the right-angle surface 32 when the U-shaped gripper 13 passes through, and enough U-shaped grippers 13 pass through.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
