Embodiment Construction
[0029] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.
[0030] Such as figure 1 and figure 2 The present invention discloses a boring tool setting device for hole machining, including a tool setting instrument body 10, a dial indicator 20, and a calibration structure 30. The calibration structure 30 includes a set of center calibration blocks 31 and at least one set of aperture calibration blocks. The center calibration block 31 and the aperture calibration block are horizontal columns whose vertical section is an arc section, the center calibration block 31 is fixedly connected adjacent to the aperture calibration block, and the bottom surfaces of the two are on the same plane, and the diameter of the center calibration block 31 The rod diameter of the workpiece is the same, and the diameter of the aperture calibration block is the same as the aperture of the workpiece. The tool setting instrumen...

The invention discloses a tool setting device of a hole machining boring tool. The tool setting device of the hole machining boring tool comprises a tool setting instrument body, a dial indicator and a calibration structure, wherein the calibration structure comprises a group of center calibration blocks and at least one group of aperture calibration blocks, the center calibration blocks and the aperture calibration blocks are horizontally-positioned column bodies of which the vertical cross sections are arc-shaped, the center calibration blocks and the aperture calibration blocks are adjacently and fixedly connected, the bottom surfaces of the center calibration blocks and the aperture calibration blocks are positioned in the same plane, the diameter of the center calibration blocks is the same as the rod diameter of a boring tool, the diameter of the aperture calibration blocks is the same as that of a blade of the boring tool, the top end of the tool setting instrument body is provided with a through dial indicator installation hole, the dial indicator is arranged on the tool setting instrument body through the dial indicator installation hole, the tool setting instrument body is positioned on the center calibration blocks, the bottom of the tool setting instrument body is designed to be attached to the outer outlines of the center calibration blocks, and a detection head of the dial indicator is positioned above the aperture calibration blocks by penetrating through the dial indicator installation hole. According to tool setting device of the hole machining boring tool, disclosed by the invention, tool setting is carried out by utilizing a principle of V-shaped block location and calibration tool setting of calibration blocks, the machining accuracy of a hole is effectively ensured, the cost is low, and the operation is convenient.
Description
technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a tool setting device for a tool. Background technique [0002] In the finishing process of part holes (such as the cylinder hole and crankshaft hole of the cylinder block; the camshaft hole of the cylinder head, etc.), due to the high machining accuracy and shape and position tolerance requirements of the hole, we often use a special fine boring tool for the hole Finishing to ensure the machining accuracy of the hole. However, before the initial processing of the part or after the tool is replaced due to the wear of the boring blade during a period of tool processing, it is necessary to perform tool calibration of the machining size of the boring tool. bit precision. [0003] Due to the large diameter and long length of the processing tool, it is impossible to detect the tool diameter by using the commonly used pneumatic tool setting instrument (the detectio...
