Description

Technical Field

[0001] This application relates to the field of measuring the arc surface of parts, and more specifically, to a device and machine tool for aligning the center vertex of an arc surface. Background Technology

[0002] In the field of machining, we often encounter rotating parts, such as shafts and cylinders. These parts require the machining of threaded holes on the curved surface or keyways on the outer diameter of the shaft.

[0003] To find the exact center of a workpiece when machining screw holes or keyways, the traditional method is to attach a dial indicator to the boring bar, rotate the boring bar, and use the dial indicator to touch the two arc surfaces of the workpiece to find the center of the outer circle's apex. This method is time-consuming, labor-intensive, and inaccurate. For workpieces with large outer circles and heights, using a dial indicator is even more inconvenient and inaccurate. Utility Model Content

[0004] The purpose of this application is to provide a device and machine tool for aligning the center vertex of an arc surface, which can quickly find the center vertex of the arc surface of a rotating part without the need for complicated measuring tools and steps, thus saving alignment time and reducing the difficulty of operation for workers.

[0005] In one aspect, this application provides a device for aligning the center vertex of an arc surface, comprising a conical component and a dial indicator.

[0006] The conical component includes a tail end and a head end; the tail end of the conical component is provided with a conical shank for connecting and fixing with the boring bar of a machine tool; a notch is provided between the head end and the tail end of the conical component, and the head end of the conical component is provided with a mounting hole along its axis, the mounting hole extending from the head end of the conical component into the notch.

[0007] The dial indicator includes a body, a sleeve connected to the body, and a measuring rod movably installed in the sleeve; the body of the dial indicator is placed in the notch, the sleeve is inserted into the mounting hole and fixed, and the measuring rod extends out from the head end of the conical component; the axis of the measuring rod coincides with the axis of the conical component.

[0008] In one feasible embodiment, a threaded hole is provided on the body structure of the cone-shaped component corresponding to the mounting hole. The threaded hole extends from the body surface of the cone-shaped component to the mounting hole, and a screw is fitted into the threaded hole to tighten and fix the sleeve of the dial indicator.

[0009] In one feasible embodiment, the cone-shaped component is a one-piece molded structure.

[0010] In one feasible embodiment, the cone component includes a cone and a cone shank detachably connected to the tail end of the cone.

[0011] In one feasible embodiment, a connecting stud is provided at the end of the cone facing the cone shank, and a threaded hole is provided at the end of the cone shank facing the cone. The cone shank and the cone are connected as one unit through the engagement of the threaded hole and the connecting stud.

[0012] In one feasible embodiment, the cone component further includes a head that is detachably connected to the cone tip;

[0013] The notch is provided on the cone, and the cone has a through hole at its head end, with an internal thread on the inner wall of the through hole;

[0014] The mounting hole is provided at the center of the head, and an external thread is provided on the outer periphery of the head, the external thread of the head engaging with the internal thread of the through hole;

[0015] The head is provided with a threaded hole and the screw is installed thereon.

[0016] Secondly, this application also provides a machine tool, including the aforementioned arc surface alignment center vertex device, and also includes a tool mounting part;

[0017] The taper shank of the arc surface centering vertex aligning device is detachably mounted on the tool mounting section.

[0018] Compared with the prior art, the beneficial effects of this application include at least the following: When using the arc surface alignment center vertex device of this application, the dial indicator and the conical part are assembled, and then the cone shank of the conical part is installed on the tool mounting part of the machine tool. The end of the measuring rod of the dial indicator is in close contact with the arc surface of the workpiece. As the machine tool moves left and right, the end of the measuring rod of the dial indicator will move along the arc surface. The maximum or minimum value displayed by the dial indicator is the center vertex of the arc surface of the rotating part. After finding the center vertex, the axis is kept stationary and the axis of the tool mounting part of the machine tool is not moved. The device is moved away from the rotating part. Then the arc surface alignment center vertex device is removed and a drill bit or end mill is installed to directly process the workpiece.

[0019] This application presents a standalone tooling unit that can be easily mounted on the tool mounting section of a machine tool. Furthermore, the axis of the arc surface alignment center vertex device is the tool axis. Therefore, after finding the center vertex, simply replacing it with a machining tool (drill or end mill) will align the tool with the center vertex of the arc surface, allowing for direct drilling or keyway machining. Thus, the arc surface alignment center vertex device of this application has a simple structure, can quickly find the center vertex of the arc surface of a rotating part, eliminates the need for complex measuring tools and procedures, saves alignment time, and reduces the difficulty of operation for workers.
