Description

Technical Field

[0001] This utility model belongs to the field of copper busbar processing technology, specifically a chamfering knife and chamfering device. Background Technology

[0002] After the copper busbar is cut, it needs to be chamfered and deburred. However, in the existing technology, the chamfering of the copper busbar edges is mostly done manually, which results in inconsistent chamfering quality and low efficiency because the copper busbar needs to be flipped over to do manual chamfering on the other side.

[0003] However, some existing chamfering devices use chamfering blades that can only chamfer one side, requiring the copper busbar to be flipped before the other side can be chamfered, which still results in low efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a chamfering knife and chamfering device, which can process two sides of the end of the copper busbar simultaneously without flipping the copper busbar through the two cutting edges of two annular inclined surfaces, thus solving the problem of low efficiency in the prior art that requires flipping the copper busbar before chamfering the other side.

[0005] The technical solution of this utility model is as follows: Firstly, a chamfering tool includes: a tool body, wherein a clamping part is provided at the end of the tool body.

[0006] The side wall of the blade body is provided with a first groove, which is an annular groove arranged around the central axis of the blade body.

[0007] The first groove includes two annular inclined surfaces, and the included angle between the two annular inclined surfaces matches the chamfer angle of the copper busbar.

[0008] The side wall of the blade body is also provided with a second groove, which intersects with two annular inclined surfaces to form at least two cutting edges.

[0009] In a further embodiment of the first aspect, the included angle between the two annular inclined planes is between 80 and 100°.

[0010] In a further embodiment of the first aspect, the included angle between the two said annular inclined planes is 90°.

[0011] In a further embodiment of the first aspect, the two annular inclined surfaces of the first groove are symmetrically fitted.

[0012] In a further embodiment of the first aspect, the cross-section of the first groove is a "V" shaped structure.

[0013] In a further embodiment of the first aspect, the depth of the second groove is greater than or equal to the depth of the first groove, so that the second groove penetrates the first groove and can penetrate two annular inclined surfaces. The length of the cutting edge is equal to the width of the annular inclined surface, and the cross-section of the first groove is a "V" shaped structure, which allows the cutting edges of the two annular inclined surfaces to connect, so that the chamfering cutter can chamfer all copper busbars smaller than the maximum spacing of the first groove.

[0014] In a further embodiment of the first aspect, the second groove extends along the central axis of the cutter body.

[0015] In a further embodiment of the first aspect, the cross-section of the second groove is a "V" shaped structure.

[0016] In a further embodiment of the first aspect, the chamfering cutter includes at least two second grooves, which are equally distributed around the central axis of the cutter body.

[0017] Secondly, a chamfering device includes: a pressing mechanism, a displacement mechanism, a chamfering power mechanism, and the chamfering blade described in the first aspect.

[0018] The displacement mechanism is located on one side of the pressing mechanism, the chamfering power mechanism is installed on the displacement mechanism, and the chamfering blade is installed on the chamfering power mechanism through the clamping part.

[0019] The pressing mechanism is used to position the end of the copper busbar.

[0020] The displacement mechanism is used to drive the chamfering power mechanism and the chamfering cutter to move along the side of the copper busbar.

[0021] The chamfering power mechanism is used to drive the chamfering cutter to rotate.

[0022] The beneficial effects of this utility model are: by matching the included angle between the annular inclined surfaces with the chamfering angle of the copper busbar, and by forming at least two cutting edges by the intersection of the second groove with the two annular inclined surfaces, the cutting edges can simultaneously process the two sides of the end of the copper busbar without flipping the copper busbar when the chamfering device drives the blade body to rotate through the clamping part. This solves the problem of low processing efficiency in the prior art, which requires flipping the copper busbar before chamfering the other side. Attached Figure Description

[0029] This utility model discloses a chamfering knife and a chamfering device. The chamfering device includes a power mechanism, a sensor, and a control device such as a PLC. The power mechanism and the sensor are connected to the control device, which controls the coordination of each power mechanism. Through the two cutting edges of the two annular inclined surfaces, the two sides of the copper busbar can be processed simultaneously without flipping the copper busbar.

[0030] Firstly, such as Figure 1 and 2 The chamfering tool shown includes: a tool body 1, and a clamping part 2 at the end of the tool body 1.

[0031] The side wall of the cutter body 1 is provided with a first groove 11, which is an annular groove arranged around the central axis of the cutter body 1.

[0032] The first groove 11 includes two annular inclined surfaces, the included angle between the two annular inclined surfaces matching the chamfer angle of the copper busbar.

[0033] The side wall of the blade body 1 is also provided with a second groove 12, which intersects with two annular inclined surfaces to form at least two cutting edges.

[0034] Regarding the first groove 11, the included angle between the two annular inclined surfaces is between 80° and 100°. In a preferred embodiment, the included angle between the two annular inclined surfaces is 90°.

[0035] The two annular inclined planes of the first groove 11 are symmetrically fitted together.

[0036] Two of the annular inclined surfaces are symmetrically fitted about a plane that is perpendicular to the central axis of the blade body 1. In a preferred embodiment, the included angle between the two annular inclined surfaces is 90°, so that the included angle between each annular inclined surface and the plane of symmetry is 45°, so that the chamfering blade simultaneously chamfers both sides of the copper busbar at a 45° angle.

[0037] In this embodiment, the cross-section of the first groove 11 is a "V" shaped structure, such as... Figure 1 and 3 The two annular inclined planes shown are joined to form the first groove 11 of a "V" shaped structure.

[0038] Regarding the second groove 12, the depth of the second groove 12 is greater than or equal to the depth of the first groove 11, so that the second groove 12 penetrates the first groove 11, that is, the distance from the second groove 12 to the central axis of the cutter body 1 is less than or equal to the distance from the first groove 11 to the central axis of the cutter body 1.

[0039] In this embodiment, the second groove 12 extends along the central axis of the cutter body 1.

The chamfering power mechanism 5 is mounted on the displacement mechanism 4. The chamfering knife is mounted on the chamfering power mechanism 5 through the clamping part 2.

[0044] The pressing mechanism 3 is used to position the end of the copper busbar, such as... Figure 3 The pressing mechanism 3 shown includes a cylinder mounted on the frame and a pressure plate mounted on the cylinder. The pressure plate is located on one side of the chamfering knife, and the cylinder is used to drive the pressure plate to move vertically.

Figure 3 and 4 The displacement mechanism 4 shown includes a vertical electric cylinder mounted on the frame and a horizontal electric cylinder mounted on the vertical electric cylinder. The chamfering power mechanism 5 is mounted on the horizontal electric cylinder.
