Description

Technical Field

[0001] The utility model relates to the technical field of boring machines, and particularly relates to a double-edged tool bar for a boring machine. Background Technique

[0002] A boring machine is a machine tool mainly used to bore prefabricated holes in workpieces with a boring tool. Usually, the rotation of the boring tool is the main movement, and the movement of the boring tool or the workpiece is the feed movement. It is mainly used for processing high-precision holes or fine machining of multiple holes completed by one positioning. When machining on a boring machine, a double-edged tool bar is required to bore the workpiece.

[0003] Among them, when the traditional double-edged tool bar is in use, the use length of the double-edged tool bar is mostly fixed. This fixed-length use method causes the double-edged tool bar to be unable to bore workpieces with a relatively deep boring depth during boring, resulting in limitations in boring. When it is necessary to equip a double-edged tool bar with a corresponding length, it will cause waste of resources and increase the processing cost, thus unable to meet the usage requirements of customers. For this reason, we propose a double-edged tool bar for a boring machine to solve the above problems. Content of the Utility Model

[0021] In this embodiment: The present utility model can jointly form a double-edge cutter bar by setting the positioning tube 1, the lengthening cutter bar 2, the cutter head 3, the blade 4, the limit bolt 5 and the threaded pin groove 6. At the same time, the setting of the positioning tube 1, the lengthening cutter bar 2, the limit bolt 5 and the threaded pin groove 6 can facilitate the adjustment of the use length of the double-edge cutter bar. By setting the above structure, the double-edge cutter bar has the advantage of having a length adjustment function during use, solving the problem that the traditional double-edge cutter bar does not have a length adjustment function during use, so as to meet the use needs of customers and avoid limitations in boring.

[0022] As a technical optimization scheme of the present utility model, a stud 7 is fixedly connected to the left side of the cutter head 3. A positioning groove 8 matching with the stud 7 is formed on the right side of the lengthening cutter bar 2. The outer surface of the stud 7 is threadedly connected to the inner surface of the positioning groove 8.

[0023] In this embodiment: By setting the stud 7 and the positioning groove 8, it is convenient to threadedly install the connection part of the lengthening cutter bar 2 and the cutter head 3. At the same time, it is convenient to disassemble and replace the cutter head 3 later. The thread direction is opposite to the processing rotation direction, so there is no need to worry about loosening during processing.

[0024] As a technical optimization scheme of the present utility model, a guide plate 9 is fixedly connected to the left side of the lengthening cutter bar 2. Guide grooves 10 matching with the guide plate 9 are formed at the top and bottom of the inner cavity of the positioning tube 1. The outer surface of the guide plate 9 is slidably connected to the inner surface of the guide groove 10.

[0025] In this embodiment: By setting the guide plate 9 and the guide groove 10, the lengthening cutter bar 2 can be guided and limited.

[0026] As a technical optimization scheme of the present utility model, a protective sleeve 11 is arranged on the outer surface of the positioning tube 1. A tube cap 12 is threadedly connected to the outer surface of the protective sleeve 11.

[0027] In this embodiment: By setting the protective sleeve 11 and the tube cap 12, it is convenient to protect the positioning tube 1, the lengthening cutter bar 2, the cutter head 3 and the blade 4.

[0028] As a technical optimization solution of the present utility model, a buffer pad 13 is fixedly connected to the right side of the inner cavity of the tube cap 12, and the connection part between the outer surface of the buffer pad 13 and the blade 4 is closely attached.

[0029] In this embodiment: By providing the buffer pad 13, the connection part between the blade 4 and the tube cap 12 can be protected, and at the same time, it is limited to avoid moving and colliding.

[0030] As a technical optimization solution of the present utility model, a label 14 is adhesively bonded to the outer surface of the protective sleeve 11, and the connection part between the outer surface of the protective sleeve 11 and the positioning tube 1 is closely attached.

[0032] As a technical optimization solution of the present utility model, the number of the threaded pin slots 6 is twelve, and the threaded pin slots 6 are equally spaced on the upper and lower sides of the lengthened cutter bar 2.

[0033] Working principle: Through the positioning tube 1, the lengthened cutter bar 2, the cutter head 3, the blade 4, the limit bolt 5 and the threaded pin slot 6, a double-edge cutter bar can be jointly constructed. When the working length of the double-edge cutter bar needs to be adjusted, the staff pulls the cutter head 3, so that the cutter head 3 drives the lengthened cutter bar 2 to move to the right. At the same time, the lengthened cutter bar 2 drives the guide plate 9 to slide on the inner surface of the guide groove 10. When the cutter head 3 drives the lengthened cutter bar 2 to move to the appropriate working length, the lengthened cutter bar 2 drives the corresponding threaded pin slot 6 to move to the position corresponding to the limit bolt 5. Then, the staff rotates the limit bolts 5 on both sides in turn, so that the limit bolts 5 are screwed and rotated on the inner surface of the positioning tube 1 and inserted into the inner cavity of the threaded pin slot 6, thereby limiting the connection part between the lengthened cutter bar 2 and the positioning tube 1, completing the adjustment of the working length of the double-edge cutter bar, and thus facilitating the adjustment of the boring depth of the double-edge cutter bar for the workpiece. The device is simple to operate and convenient to adjust and use, so as to meet the use requirements of customers and avoid limitations in boring.
