Problems solved by technology

Milling machines generally use metric tapers, but with the continuous improvement of cutting precision, the existing method of using metric tapers as the connection between the milling machine spindle and the tool can no longer meet the new processing requirements. The main problem is that the connection rigidity is not enough, and at high Under the high speed, due to the expansion of the spindle taper hole, the repeated positioning accuracy and tool change accuracy are reduced, and the clamping effect is not good enough

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 and 2 As shown, a tool positioning and clamping mechanism for a milling machine includes a tool 1, a tool handle body 3 and a pull rod 4, the tool 1 is an end mill, and the tool handle body 3 is partly accommodated in the machine tool spindle 5 And fixed with the machine tool spindle 5, the tool handle body 3 is closely attached to the machine tool spindle, the tool handle body 3 is provided with a center hole 3.1, the tool 1 is sleeved in the center hole 3.1, the tie rod 4 is accommodated in the center hole 3.1, and the tie rod 4 One end is connected with the handle body 3, and the other end of the pull rod 4 is connected with the tool 1.

[0018] Said knife handle body 3 is fixed with the machine tool spindle 5, means that the machine tool spindle 5 outer peripheral surface is provided with a radial hole 5.1, and the tool handle bo...

Abstract

The invention discloses a tool positioning-clamping mechanism for a milling machine, which comprises a tool (1), a tool shank (3) and a pull bar (4). The tool shank (3) is partially contained in a machine spindle (5) and fixed to the same, the tool shank (3) is provided with a center hole (3.1), the tool (1) is nested into the center hole (3.1), the pull bar (4) is contained in the center hole (3.1), one end of the pull bar (4) is connected with the tool shank (3) and axially limited, the other end of the pull bar (4) is fixedly connected with the tool (1), and accordingly the tool (1) is fixedly connected with the machine spindle (5). The connection way is higher in connection rigidity than the original Morse taper connection way, connection is more stable, and clamping is better. When the machine spindle is in high-speed rotation, the tool is more stable in rotation and less apt to fall from the spindle, and safety factor is higher.

Description

technical field [0001] The invention relates to the field of machine tool processing, in particular to a tool positioning and clamping mechanism for milling machines. Background technique [0002] At present, when processing the cylinder head, it is necessary to use a milling machine for processing. The tool used for the milling machine and the spindle of the milling machine mainly rely on Morse taper for clamping and positioning. Morse taper is an international standard for taper, which is used for static fit for precise positioning. Because the taper is small, a certain torque can be transmitted, and because of the taper, it is easy to disassemble. The Morse taper uses the principle of friction. Within a certain range of taper, the workpiece can be disassembled freely. Milling machines generally use metric tapers, but with the continuous improvement of cutting precision, the existing method of using metric tapers as the connection between the milling machine spindle and t...
