Description

Technical Field

[0001] The utility model relates to the field of machining milling cutters, in particular to a tungsten steel milling cutter which is convenient for accommodating chips. Background Art

[0002] Tungsten steel milling cutter is a kind of cutting tool made of tungsten steel. It is mainly used in CNC machining centers and CNC engraving machines. It can also be installed on ordinary milling machines to process some relatively hard and uncomplicated heat-treated materials. Tungsten steel milling cutter is widely used and uses high-speed processing.

[0003] The blade of the tungsten steel milling cutter will be equipped with a chip groove. During the processing of the tungsten steel milling cutter, the chips of the workpiece cut will be discharged through the chip groove. Therefore, the size of the chip groove determines the chip removal quality of the tungsten steel milling cutter. The chip groove of the tungsten steel milling cutter is usually set between two adjacent blades. The more blades there are, the more chip grooves there are. At this time, the strength of the blade is greater, and the chip removal effect of the chip groove is worse. Anyway, the larger the chip groove, the fewer the cutting edges of the tungsten steel milling cutter, and the strength of the milling cutter is lower. Moreover, after long-term processing and use, if the existing tungsten steel milling cutter is damaged, it can only be replaced as a whole, which is inconvenient to use. Utility Model Content

It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Please see the attached Figure 1-6 , this application provides the following technical solutions.

[0026] Example 1

[0027] The tool holder 2 is provided with a plurality of slots 5 for receiving the tool, and the plurality of slots 5 are provided with a plurality of slots 6 for receiving the tool.

[0028] After the clamping tool handle 1 and the blade body 2 are spliced, a combined fixing component is set to be combined and fixed. The combined fixing component passes through the blade body 2 and is inserted into the clamping tool handle 1. The combined fixing component includes an alloy reinforcing rod 10 and a pulling block 11. A fixed screw sleeve 9 is movably provided in the clamping tool handle 1, and the fixed screw sleeve 9 is sleeved on one side of the clamping tool handle 1 with the alloy reinforcing rod 10. A fixing groove 8 is provided at the center of one end of the clamping tool handle 1 away from the blade body 2, and a connecting groove 4 is provided at the center of one end of the blade body 2 away from the clamping tool handle 1. A pipe groove is provided in the center of the clamping tool handle 1 and the blade body 2, and the two pipe grooves are respectively connected to the fixing groove 8 and the connecting groove 4. The centers of the connecting grooves 4 are connected, and the pulling block 11 is integrally arranged at one end of the alloy reinforcement rod 10. The alloy reinforcement rod 10 movably passes through the tube groove of the clamping tool handle 1 and the blade body 2. The pulling block 11 is placed in the connecting groove 4. The diameter of the connecting groove 4 is larger than the diameter of the tube groove. The diameter of the pulling block 11 is larger than the diameter of the alloy reinforcement rod 10. When the alloy reinforcement rod 10 passes through the tube groove from one side of the connecting groove 4 of the blade body 2, the pulling block 11 is inserted into the connecting groove 4. When the alloy reinforcement rod 10 is pulled away from the side of the pulling block 11, the alloy reinforcement rod 10 can pull the blade body 2 and the clamping tool handle 1 to be pressed and fixed.

[0029] The end of the alloy reinforcing rod 10 away from the pulling block 11 is inserted into the fixed groove 8 and is provided with a fixed external thread 12. The fixed screw sleeve 9 is rotated and placed in the fixed groove 8. The lower end of the fixed screw sleeve 9 is provided with an internal thread groove. The fixed screw sleeve 9 is sleeved with the fixed external thread 12 of the alloy reinforcing rod 10 through the internal thread groove. The upper end center of the fixed screw sleeve 9 is connected to the internal thread groove and is provided with a connecting groove. An auxiliary rubber pad 13 is provided on one side of the internal thread groove close to the connecting groove, and one side of the auxiliary rubber pad 13 is in contact with the alloy reinforcing rod 10. When the alloy reinforcing rod 10 passes through the pipe groove of the blade body 2 and enters the fixed groove 8, the fixed screw sleeve 9 pulls the alloy reinforcing rod 10 through the internal thread groove, so that the clamping tool handle 1 and the blade body 2 are pressed and fixed. The setting of the auxiliary rubber pad 13 can buffer the vibration of the blade body 2 and the clamping tool handle 1 during use, and reduce the possibility of the fixed screw sleeve 9 loosening due to self-rotation.

[0030] In this embodiment, when the blade body 2 is connected to the combination slot 5 of the clamping tool handle 1 through the insertion rod, a plurality of key strips 7 are simultaneously inserted into a plurality of synchronous key slots 6. When the clamping tool handle 1 rotates, the blade body 2 rotates synchronously, and the transmission is stable and reliable. Then the alloy reinforcement rod 10 is passed through the blade body 2 and inserted into the clamping tool handle 1. When the fixed screw sleeve 9 threadably connects the alloy reinforcement rod 10 and further rotates, the blade body 2 can be pulled by the pull block 11 to further tighten and fix the clamping tool handle 1 and the blade body 2 to maintain the structural stability of the entire tungsten steel milling cutter.

[0031] Embodiment 2, on the basis of embodiment 1, a clamping limiting component is set to further limit the rotation of the fixed screw sleeve 9 to prevent the connection between the clamping tool handle 1 and the blade 2 from loosening, the clamping limiting component is arranged on the four sides of the clamping tool handle 1 close to the fixed screw sleeve 9, and the clamping limiting component includes a plurality of pressing springs 15, the clamping tool handle 1 is symmetrically provided with a plurality of strip grooves 14 on the four sides of the fixed groove 8, and the plurality of pressing springs 15 are respectively arranged in the plurality of strip grooves 14, and the plurality of pressing springs 15 are respectively provided ...

The inner peripheral side of the tightening spring piece 15 is flush with the inner wall of the fixing groove 8. When the outer side of the tightening spring piece 15 is squeezed by the milling cutter installation sleeve in the prior art, the tightening spring piece 15 tilts and deforms toward the inside of the fixing groove 8, clamping the outer peripheral side of the fixing screw sleeve 9, and at the same time cooperating with the anti-slip pattern 16 to keep the fixing screw sleeve 9 stable, thereby ensuring the stable connection between the clamping tool handle 1 and the blade body 2;

[0032] In addition, the alloy reinforcing rod 10 can be hollow to facilitate processing and heat dissipation of the blade 2. The metal strength of the alloy reinforcing rod 10 is greater than that of the blade 2.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
