Description
Technical Field
The utility model belongs to a cutter used by numerical control machining equipment, which is applied to the removal of burrs at the inner hole edges of space intersecting holes.
Background
In the field of machine manufacturing, the removal of burrs after machining metal parts has been a relatively difficult problem, especially for small holes on non-planar surfaces (here generally referred to as holes smaller than phi 5), when small holes are drilled in large hole walls, an intersecting line resembling an ellipse is formed on the inner surface of the large hole, see fig. 7, and burrs are often formed at the intersecting line, see fig. 8. There are two general methods of deburring: one is to remove after the work piece processing, and the special deburring equipment is adopted to finish the work piece processing, but the equipment investment is large and the cost is high. Some of the steps are finished manually, but the labor intensity is high, the efficiency is low, and omission is easy; the other mode is to directly remove burrs on equipment for machining holes, and the burrs are removed by adopting a ball cutter to carry out numerical control programming, but when the hole diameter is smaller, the numerical control programming is troublesome and easy to cut, and the burrs are removed by adopting a hairbrush, but the removal is not thorough.
The existing common deburring tool usually has a cutting edge on one side, and even if the tool has the same cutting edge at a symmetrical position, the deburring tool is easy to remove burrs formed after drilling on a plane because the cutting edge is used for cutting in one rotation direction, but burrs at eccentric intersecting holes cannot be removed well, and even only half of burrs at intersecting holes can be removed.
Disclosure of Invention
The utility model provides a cutter for removing burrs of intersecting holes, which aims to solve the problem that burrs formed at the intersection of two holes are difficult to remove when a workpiece processed by numerical control processing equipment is communicated with the small hole and the large hole.
The technical scheme includes that the cutter comprises a cutter body, a cutter open slot, a reverse cutting edge, a forward rotating cutting edge, a cutter guiding part and a cutter handle clamping part, wherein the rear part of the cutter body is fixedly connected with the cutter handle clamping part, the cutter open slot is formed in the front part of the cutter body, the reverse cutting edge and the forward rotating cutting edge are respectively and fixedly connected with the outer side of the cutter body at the cutter open slot, and the cutter guiding part is positioned below the reverse cutting edge and the forward rotating cutting edge.
The included angle of the cutter open slot is 5 degrees.
The angle A of the main cutting edge of the forward rotating cutting edge is 150 degrees, the angle of the lower cutting edge is 130 degrees, and the included angle between the main cutting edge and the lower cutting edge is provided with a round angle R0.3.
The angle B of the main cutting edge of the reverse cutting edge is 150 degrees, the angle of the lower cutting edge is 130 degrees, and the included angle between the main cutting edge and the lower cutting edge is provided with a fillet of R0.3.
The utility model has the advantages of novel structure, capability of removing burrs around the intersecting holes through one forward rotating cutting edge and one backward rotating cutting edge, clean and thorough removal, ideal effect, almost no longer need to remove burrs at the subsequent step, higher efficiency, suitability for removing burrs at intersecting line positions formed by intersecting small holes and large holes, and suitability for removing burrs at eccentric intersecting line positions of two holes on numerical control equipment.

Detailed Description
Referring to fig. 1, 2 and 4, the cutter comprises a cutter body 1, a cutter open slot 2, a reverse cutting edge 3, a forward rotating cutting edge 4, a cutter guiding part 5 and a cutter handle clamping part 6, wherein the rear part of the cutter body 1 is fixedly connected with the cutter handle clamping part 6, the cutter open slot 2 is arranged at the front part of the cutter body 1, the reverse cutting edge 3 and the forward rotating cutting edge 4 are respectively fixedly connected with the outer side of the cutter body at the cutter open slot 2, and the cutter guiding part 5 is positioned below the reverse cutting edge 3 and the forward rotating cutting edge 4;
referring to fig. 2, the included angle of the cutter open slot 2 is 5 degrees;
referring to fig. 3, the angle a of the main cutting edge of the forward rotation cutting edge 4 is 150 degrees, the angle of the lower cutting edge is 130 degrees, and the included angle between the main cutting edge and the lower cutting edge has a fillet of R0.3;
referring to fig. 3, the angle B of the main cutting edge B of the reverse cutting edge 3 is 150 degrees, the angle of the lower cutting edge is 130 degrees, and the included angle between the main cutting edge and the lower cutting edge has a rounded angle R0.3.
Principle of operation
The tool shank clamping part 1 is a position for clamping a numerical control tool shank during machining, the tool opening groove 2 ensures enough compression amount when the tool enters the hole, the tool reverse cutting edge 3 is used for cutting when the tool reverses, the tool forward cutting edge 4 is used for cutting when the tool reverses, in order to achieve ideal cutting effect, the distance between the tool forward cutting edge 4 and the reverse cutting edge 3 is larger than the diameter of a machined hole, when the tool forward cutting edge 4 and the reverse cutting edge 3 are combined towards the middle and reach the maximum compression amount of the tool opening groove 2, the distance between the tool forward cutting edge and the reverse cutting edge is smaller than the diameter of the hole, and the tool guiding part 5 is used for guiding the tool at the beginning of entering the hole, and the diameter of the tool is smaller than the diameter of the hole to be machined.
When a certain hole is machined along with forward rotation (clockwise) of the main shaft, the cutter guide part 5 firstly enters the small hole, the burr cutter is prevented from deviating from the small hole, the cutter forward rotation cutting edge 4 and the cutter reverse rotation cutting edge 3 are gathered towards the center of the cutter along with the movement of the cutter to the vertical direction and reach the intersecting line position, the cutter continues to move to the vertical direction, the cutter forward rotation cutting edge 4 and the cutter reverse rotation cutting edge 3 are opened under the action of elastic force and centrifugal force, and the cutter forward rotation cutting edge 4 starts to cut and remove burrs at the left half part of the intersecting line position. In contrast, with respect to the burrs of the right half, since the cutter forward rotation cutting edge 4 and the cutter reverse rotation cutting edge 3 are rotated from the inner wall of the small hole toward the small Kong Waixuan, the burrs of the right half cannot be removed, and when the cutter cutting moves to the bottommost portion of the intersecting line, the burrs of the left half are removed. Then the burr cutter can be controlled to be reversed (anticlockwise) by the numerical control machine tool program and start to move upwards, at this time, the cutter reversing cutting edge 3 starts to remove the burrs of the right half part, and similarly, the burrs of the left half part cannot be removed at this time. Along with the gradual upward movement of the cutter, burrs on the right half part are removed, the cutter is withdrawn from the small hole, and the machine tool is controlled to rotate positively through a numerical control machine tool program. Thus, burrs at the whole intersecting hole position are removed.
