Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Please refer to fig. 1-3, a numerical control lathe tool comprises a tool holder 1, a threaded hole 2 is formed in the tool holder 1, an annular tooth 3 is fixedly connected to the end surface of the tool holder 1 at one side of the threaded hole 2, a fixing block 4 is arranged at one side of the tool holder 1 at the annular tooth 3, a circular block 5 is fixedly connected to one end of the tool holder 4 close to the tool holder 1, the annular tooth 3 is also fixedly connected to one end of the circular block 5 close to the tool holder 1, fastening bolts 6 are arranged in the fixing block 4 and the circular block 5, the fixing block 4 is fixedly connected with the tool holder 1 through the fastening bolts 6, a boring blade 7 and an internal thread blade 8 are arranged at two ends of the fixing block 4, and the boring blade 7 and the internal thread blade 8 are fixedly connected with the fixing block 4 through the fastening bolts 9.

Wherein, the position corresponding to the fastening bolt 6 on the fixed block 4 is provided with a sinking groove 10, and the depth of the sinking groove 10 is greater than the head height of the fastening bolt 6. This kind of design through setting up the heavy groove 10 that is darker than fastening bolt 6 head, can make fastening bolt 6's head be located heavy groove 10, prevents that fastening bolt 6's head from outstanding, causes the interference when processing blind hole or step hole, has the practicality.

Wherein, the cutting tool tip of the boring blade 7 and the cutting tool tip of the internal thread blade 8 are positioned at the same horizontal height, and the cutting surface of the boring blade 7 and the cutting surface of the internal thread blade 8 are positioned at the same side of the fixing block 4. This kind of design, the cutting knife tip through setting up bore hole blade 7 and the cutting knife tip of internal thread blade 8 are located same level, it is convenient when rotating fixed block 4 and adjusting, the cutting knife tip of bore hole blade 7 and the cutting knife tip of internal thread blade 8 are in same level with the lathe centre of rotation, can not receive the interference during processing and cause the sword that collapses, improve blade life, it is more convenient to adjust, cutting face through setting up bore hole blade 7 and the cutting face of internal thread blade 8 are located same one side of fixed block 4, be convenient for change the blade.

Wherein, the boring blade 7 and the internal thread blade 8 are both obliquely arranged on the fixing block 4, and the boring blade 7 and the internal thread blade 8 are both far away from the fastening bolt 6 and are obliquely inclined downwards. By the design, when the blade is used for cutting, the cutting edge is in contact with the surface of a workpiece, so that the interference is avoided, and the cutter breakage is avoided.

Wherein, a plurality of scale marks 11 which are arranged at equal intervals are arranged on the knife handle 1 corresponding to the annular teeth 3, and a reference line 12 is arranged on the circular block 5 corresponding to the annular teeth 3. This kind of design plays the reference effect when rotating fixed block 4 and carrying out height control or change different fixed blocks 4, and adjusting position is more accurate, and the installation effectiveness is higher.

The working principle is as follows: when the lathe tool is used, the tool holder 1 is installed on a lathe tool rest, the boring blade 7 and the internal thread blade 8 are installed on the fixing block 4 through the fastening screws 9 respectively, then the fixing block 4 is installed on the tool holder 1, the fixing block 4 is rotated to enable the cutting tool tips of the boring blade 7 and the internal thread blade 8 to be located on the same straight line with the rotating center of a lathe spindle, the two corresponding annular teeth 3 are meshed with each other, the fastening bolt 6 is screwed to fix the position, cutting can be performed at the moment, when the tool is adjusted, the lathe spindle rotates anticlockwise, the tool rest moves to drive the tool holder 1 fixed on the tool holder to move, a lathe Z shaft is moved to perform hole adjustment on the boring blade 7 by a small section of a hole lathe, then the lathe spindle rotates clockwise, the internal thread blade 8 is adjusted by the same method, then a processing program is compiled, when the spindle rotates anticlockwise, the boring blade 7 is used for boring, the hole size is processed, program control main shaft clockwise rotation, interior thread cutter 8 can carry out car internal thread processing, and the direct conversion main shaft turns to and does not need the tool changing just can carry out boring hole and car internal thread processing, and work efficiency is high, improves knife rest life, and through installing different fixed block 4, multiple processing type can be realized to different blade combinations, has reduced the knife position rate of utilization on the knife rest, equals to install more cutters, can process more complicated part.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
