Referring to fig. 1 to 7, an improved chamfering machine in the present utility model comprises a machine body 1, wherein a base 4 is arranged in the machine body 1, a support 2 capable of horizontally moving on the base 4 is arranged on the base 4, a tool apron 3 capable of vertically moving on the support 2 is arranged on the support 2, a rotatable tool bit fixing seat 6 is arranged on the tool apron 3, and a tool bit 61 is arranged on the tool bit fixing seat 6; the machine body 1 is also provided with a gear placing seat 5, the gear placing seat 5 is provided with a rotatable gear clamping device 51, and the machine body 1 is provided with a control center 11 for automatic control operation.

Specifically, as can be seen from the drawings, in the present application, the rotation axis of the gear clamping device 51 is in a vertical direction, and the rotation axis of the tool bit fixing seat 6 is in a horizontal direction, so that the machining and the movement are convenient, and the placement of the machined gear is also convenient.

In addition, in this application, the horizontal movement of base 4 passes through horizontal drive structure drive, the vertical movement of blade holder 3 passes through vertical drive structure drive, and in this structure, horizontal drive structure, vertical drive structure can be drive arrangement such as motor, cylinder, lead screw, synchronous pulley. The rotation of the tool bit holder 6 is driven by a first rotation driving structure, and the rotation of the gear clamping device 51 is driven by a second rotation driving structure, where the first rotation driving structure and the second rotation driving structure may be conventional rotation driving devices such as a motor.

The chamfering machine in the application comprises a support 2 horizontally moving on a base 4, a cutter head fixing seat 6 vertically moving on the support 2, a cutter head 61 freely moving, a gear placing seat 5 fixedly, and the cutter head 61 approaching to the gear placing seat 5 and positioned at a proper position. The chamfering device has the advantages that the whole structure is compact, chamfering operation on the gear can be rapidly completed through the matching rotation of the cutter head 61 and the gear 7, and the efficiency is high.

When the chamfering machine works, the cutter head fixing seat 6 rotates to drive the cutter head 61 to rotate at a rotating speed r 1; the gear clamping device 51 rotates to drive the gear clamped on the gear clamping device to rotate at a rotating speed r 2; the cutter head 61 is then moved relative to the gear wheel 7 such that the cutting edge 611 on the cutter head 61 is on the end face of the gear teeth 71 on the gear wheel 7, in this position: the blade 611 is in a horizontal state and is above the end surface of the gear teeth; when the cutter head 61 rotates, the cutter blade 611 completes chamfering operation on the gear teeth 71.

In this application, the cutter head 61 has two blades 611 symmetrically disposed thereon, and based on this structure, the relationship between the rotational speed r1 of the cutter head 61 and the rotational speed r2 of the gear 7 is: the blade 611 on the cutter head 61 rotates 180 degrees, and the gear 7 rotates by one tooth angle, so that the chamfering operation can be completed twice by rotating the cutter head 61 for one circle, and the efficiency is high.

Further, the blade 611 is in a horizontal state and is located above the end surface of the gear teeth as a reference position, and based on the reference position, the cutter head and the gear rotate at a moving rotation speed ratio, and during the rotation, the blade 611 completes chamfering operation on the gear teeth 71. In the chamfering operation, the blade 611 and the gear 7 only rotate, and have no relative movement in other directions, so that the chamfering device is simple to operate, and only needs to ensure a proper rotation speed ratio, and has high precision and high efficiency.

As can be seen from fig. 4 to fig. 7, in fig. 4, the blade 611 is immediately rotated to a horizontal state, in which the blade 611 is located on the end face of the gear teeth 71, and then continues to rotate, and the gear 7 is also rotated, and then, as shown in fig. 5, the blade 611 on one side starts to enter the tooth groove 72, and the chamfering operation is performed on one side of the tooth groove 72, and then, as shown in fig. 6 and fig. 7, the chamfering operation is performed on the other side of the tooth groove 72 after the blade 611, thereby completing one chamfering operation, and thus, the chamfering operation of the whole gear is completed.

In the above, the improved chamfering machine provided by the utility model has the advantages of compact structure and high chamfering efficiency, and can obviously improve the gear machining efficiency.

The scope of the present utility model includes, but is not limited to, the above embodiments, and any alterations, modifications, and improvements made by those skilled in the art are intended to fall within the scope of the utility model.
