Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically to a blind hole boring tool that facilitates chip removal. Background Technology

[0002] A boring tool is a type of boring tool, generally with a round shank, although square shanks are sometimes used for larger workpieces. It is most commonly used for internal hole machining, reaming, and contouring. It is a tool with one or two cutting sections, specifically designed for roughing, semi-finishing, or finishing existing holes. Boring tools can be used on boring machines, lathes, or milling machines.

[0003] In related technologies, traditional boring tools sometimes have a tool holder and a tool body that are screwed together, or sometimes the tool holder and the tool body are molded as one piece. Most tool holders are integral pieces with multiple cutting blades fixed on them.

[0004] However, most existing boring tools have fixed inserts, which can only cut holes of specific sizes. When holes of different sizes need to be made, frequent tool changes are required, which is inconvenient. In addition, the chip space between the insert and the tool holder body of traditional roughing boring tools is small, meaning that the machining space between the insert and the workpiece is small. The chips generated during cutting accumulate instantly, reducing the machining space and the amount of chips that can be accommodated. Furthermore, the chip evacuation groove cannot remove chips in time, and chips can easily jam the insert, affecting the normal operation of the machining process. To solve the above problems, a blind hole boring tool that facilitates chip removal is proposed to address these issues. Utility Model Content

[0005] In view of this, the present invention provides a blind hole boring tool that facilitates chip removal. By mounting the tool connector on a lathe, the cutting chips can be quickly discharged from the side of the tool through the rounded arc of the side groove during cutting, and the cutting chips can be quickly discharged from the bottom of the tool through the rounded corner of the front groove, thereby preventing chips from clogging the tool. By loosening the positioning bolt, the tool holder can be moved radially, which facilitates tool adjustment. The boring size can be adjusted with reference to the scale line. After the size is adjusted, the bolt can be tightened before boring can be performed, thus facilitating tool adjustment.

[0006] To solve the above-mentioned technical problems, this utility model provides a blind hole boring tool that facilitates chip removal, including a tool holder at the upper end of the tool connector, tool clips symmetrically arranged at the upper end of the tool holder, each tool clip having a tool groove, the tool clips slidingly disposed with the tool holder, a first cutting tool detachably disposed on each tool groove, a side discharge groove on the left and right sides of the upper half of the tool holder, and a front discharge groove on the front side of the upper half of the tool holder.

[0007] The side groove is square and extends vertically downwards from the top of the tool holder to the middle of the tool holder. The bottom of the side groove has a rounded arc, which is used to facilitate the discharge of chips from the boring tool from both sides of the tool holder.

[0008] The front slot is square and extends vertically downwards from the top of the tool holder to the middle of the tool holder. The bottom of the front slot has rounded corners to facilitate the discharge of chips from the bottom of the tool holder.

[0009] The tool holder has an upper sliding groove in the center, which facilitates the movement and adjustment of the tool holder, thereby allowing the tool holder to adjust its width. The upper sliding groove is rectangular in the middle and curved at both ends. A positioning groove is fixedly provided at the inner ring of the upper sliding groove, which is used to hold the positioning bolt.

[0010] Each positioning slot has a corresponding downward groove for the tool holder. The downward groove is used to open threaded holes. Each downward groove has a pair of threaded holes for installing positioning bolts, so that the positioning bolts can fix the tool holder on the tool holder. The downward groove is embedded in the top of the tool holder.

[0011] Each threaded hole is equipped with a positioning bolt to fix the tool holder to the tool holder, and the nut of the positioning bolt is pressed against the edge of the positioning groove.

[0012] A first insert is fixed to a corner of the tool groove away from the center of the tool holder by a first bolt. The first insert is used to cut the lathe workpiece. A second insert is set diagonally opposite the first insert. The second insert is used to install the second bolt. The second insert is used to cut different workpieces. The second insert is connected to the tool groove by the second bolt. A pressing component is fixed at the nut of the second bolt. After the second bolt is tightened, the other end of the pressing component presses the first insert a second time, thereby increasing the fastening force on the first insert. The pressing component is arc-shaped, and the other end of the pressing component is in contact with the surface of the first insert.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. By installing the tool connector on the lathe, cutting chips can be quickly discharged from the side of the tool through the rounded arc of the side groove during cutting, and cutting chips can be quickly discharged from the bottom of the tool through the rounded corner of the front groove, thus preventing chips from clogging the tool. When it is necessary to adjust the tool size, the positioning bolt is loosened. At this time, the tool holder can be moved and the positioning bolt moves in the upper slide. After the adjustment is completed, the positioning bolt is tightened so that the nut presses against the positioning groove, thus completing the installation and facilitating tool adjustment.

[0014] 2. The sliding groove is used to open the threaded hole and allow the positioning bolt to move. The threaded hole is used to install the positioning bolt, so that the positioning bolt can fix the tool holder on the tool holder. Each threaded hole is provided with a positioning bolt for fixing the tool holder on the tool holder.

[0015] 3. The first cutting tool is used to cut or drill holes in the lathe workpiece. The second cutting tool is used to install the second bolt. The second cutting tool is also used to cut different workpieces. A pressing component is fixed at the nut of the second bolt. After the second bolt is tightened, the other end of the pressing component presses the first cutting tool a second time, thereby improving the fastening force on the first cutting tool.
