Embodiment Construction
[0014] As shown in the figure, a clamping fixture for a taper shank end mill on a common boring machine, a tubular inner taper sleeve, the taper of the inner taper hole of the inner taper sleeve matches the taper taper of the taper shank end mill, and the outside of the inner taper sleeve It is a cylindrical surface, and the cylindrical surface outside the inner taper sleeve is matched with the cylindrical surface of the inner hole of the tool seat on the flat rotary disk of the boring machine.
[0015] The connection between the tapered shank end mill and the inner tapered sleeve cutter is fastened by tightening the screw behind the tapered shank of the tapered shank end mill; The screw on the side of the knife block is fastened.
[0016] The tool seat on the flat rotating disk of the boring machine is a flange-shaped tool seat. The inner hole of the flange is the same diameter as the outer diameter of the inner tapered sleeve. There are screw holes on the side of the flange....

A clamping fixture for a taper-shank vertical milling cutter arranged at a boring lathe comprises an inner taper sleeve which is combined with a taper shank of a vertical milling cutter, the conicity of the inner hole of the inner taper sleeve is identical with the conicity of the taper shank of the vertical milling cutter, the external diameter of the inner taper sleeve is in the shape of a cylinder, and the diameter of the inner taper sleeve and a cutter-rest inner hole are in close fit. The bottom of the cutter rest possesses two raised platforms which are matched with square grooves on a boring-lathe flat rotary plate, the cutter-rest inner hole is formed by boring the boring lathe self body, and the center of the inner hole is absolutely centered. The vertical milling cutter is installed in the inner taper sleeve, and the vertical milling cutter and the inner taper sleeve are connected via a screw, are tightly locked together and then are installed in the cutter rest on the flat rotary plate of the boring lathe, and two screws are employed for fixing. After the vertical milling cutter is installed, a percent meter is employed for performing centering correction on the vertical milling cutter. And then milling processing can be performed after the flat rotary plate is tightly locked.
Description
technical field [0001] The invention belongs to a boring machine auxiliary jig for machining, in particular to a jig for mounting a tapered shank end mill on a common boring machine. Background technique [0002] The end mills with a larger diameter are all tapered shank, with an internal thread structure at the end. On ordinary milling machines, the tension rod in the main shaft is tightened in the taper hole of the main shaft to realize clamping. Due to the limitation of the structure of the spindle of the ordinary boring machine. It is not possible to use the spindle pull rod to tighten the clamping end mill, thereby limiting the use of ordinary boring machines for end mills. The fixture can easily clamp the end mill, expands the variety of boring tools for ordinary boring machines, and makes processing more convenient. Contents of the invention [0003] The purpose of the present invention is to provide a clamping fixture for taper shank end mills on ordinary boring...
