Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The specific embodiment is as follows:
The cutter body 1 is provided with an installation through hole 12 which penetrates through the cutter body 1 from top to bottom and is used for penetrating a screw to connect the cutter body 1 to the cutter bar, so that detachable connection is realized. A vertical notch 11 is formed in the rear side of the lower portion of the cutter body 1, and the notch 11 avoids the position of the mounting through hole 12. The upper side surface of the notch 11 is a first positioning surface 111, namely a reference surface A; the back side surface of the notch 11 is a second positioning surface 112, namely a reference surface C; the first positioning surface 111 and the second positioning surface 112 which are perpendicular to each other form a perpendicular positioning portion, the positioning portion is attached to the positioning surface on the knife handle, positioning is carried out from two perpendicular directions, a positioning effect is achieved, and positioning accuracy is improved.
A bit support portion 13 having a stepped structure is suspended upwardly from the upper side of the cutter body 1. Specifically, the bit support portion 13 includes a first support portion 131 and a second support portion 132. More specifically, the first support portion 131 is cantilevered rightward from the right end of the cutter body 1. The second supporting portion 132 is provided with at least one, and may be one, two, three or more, so as to implement the processing of the multistage stepped hole. The plurality of second supporting portions 132 and the first supporting portion 131 are formed in a step shape which is sequentially sunk from left to right.
In this embodiment, one second supporting portion is provided as an example.
A first blade 2 is provided at the right end of the first support 131, and a second blade 3 is provided at the right end of the second support 132. Therefore, when the tool is fed rightwards, the first tool bit 2 firstly contacts the workpiece to be machined, the second tool bit 3 contacts the workpiece to machine the step with the increased hole diameter, the step hole is machined, only one tool setting and feeding are needed in the process, and machining is more convenient.
When the detachable boring cutter for machining the large-diameter hole is used, the cutter body 1 penetrates through the mounting through hole 12 through a screw to be connected to the cutter rod, the first positioning surface 111 and the second positioning surface 112 abut against the positioning surfaces of the cutter handle from two vertical directions, positioning accuracy is improved, and the cutter body 1 is effectively prevented from swinging and skewing. The cutter head supporting part 13 on the upper side surface of the cutter body 1 is in a step shape, and the workpiece hole is processed through the first cutter head 2 supported by the first supporting part 131 and the second cutter head 3 supported by the second supporting part 132 respectively, so that the step hole can be processed by one-time tool setting and feeding, and the large-diameter hole can be processed more conveniently. Meanwhile, different numbers of the second supporting parts 132 can be provided according to actual requirements of holes to be processed, so as to implement processing of stepped holes of multiple steps.
Further, the first cutting head 2 and the first supporting portion 131 are connected by welding, so that the connection is firmer.
Furthermore, the first tool bit 2 is made of PCD materials, the cutting edge is sharp, the surface finish of the machined workpiece is good, the cutting edge made of the PCD materials is high in abrasive resistance, and the service life is long.
Further, the second cutting head 3 and the second supporting portion 132 are connected by welding more firmly.
Further, the second tool bit 3 is made of PCD materials, the cutting edge is sharp, the surface finish of the machined workpiece is good, the cutting edge made of the PCD materials is high in abrasive resistance, and the service life is long.
Further, the mounting through hole 12 of the cutter body 1 is a kidney-shaped hole extending in the length direction of the cutter body 1. In this embodiment, preferentially adopt two screws, two screws set up respectively in the position of the both ends circular arc in waist type hole, compress tightly cutter body 1 on the cutter arbor for cutter body 1 atress is more even, connects more reliably.
Furthermore, the waist-shaped hole adopts a stepped hole with a sinking, so that the screw is completely hidden in the cutter body and does not protrude out of the cutter body 1 during connection, and the interference of the screw in the process of machining a workpiece is reduced.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without the technical solutions of the present invention, or the present invention can be directly applied to other occasions without the improvements, and all are within the protection scope of the present invention.
