Internal cooling type tungsten steel milling cutter clamp

Abstract

The invention discloses an internal cooling type tungsten steel milling cutter clamp. The internal cooling type tungsten steel milling cutter clamp comprises an outer connecting rod, a bayonet, a buttjoint rod, an adapter ring, an inner connecting rod, a butt joint disc, a positioning block, a connecting column, a limiting disc, a threaded column, a fixing clamping opening, a fastening nut and acooling liquid through hole. The internal cooling type tungsten steel milling cutter clamp has the beneficial effects that the outer connecting rod, the butt joint rod, the adapter ring and the innerconnecting rod are internally hollow, through the hollow structures, normal conveying of a cooling liquid is ensured, the positioning block is screwed and locked to the butt joint disc through screws,the positioning block is convenient to disassemble for position change, the fixing clamping opening is in a circular truncated cone shape and is arranged in a fork close shape, and is tightened and loosened through screwing of the fastening nut, so that the situation that the milling cutter is inconvenient to replace later is prevented.

Description

technical field [0001] The invention relates to a milling cutter fixture, in particular to an internally cooled tungsten steel milling cutter fixture, which belongs to the technical field of milling cutter fixtures. Background technique [0002] Milling cutter refers to a kind of cutting tool whose arc length is greater than 1 / 4 circle. In mold processing, some small workpieces have a draft angle on the processing surface. Ordinary R angle cutters have relatively long blade lengths, and the rigidity of the cutting tool is relatively long. Reduced, the strength and rigidity of the tool cannot meet the requirements, and the service life of the tool is short. In order to strengthen the strength and rigidity of the tool and enhance the service life of the tool, a short-edged strong milling cutter is designed to improve the rigidity and strength and ensure the precision of the mold. , the mold is processed in place at one time. When machining the hole of the workpiece, the hole i...

[0002] Milling cutter refers to a kind of cutting tool whose arc length is greater than 1 / 4 circle. In mold processing, some small workpieces have a draft angle on the processing surface. Ordinary R angle cutters have relatively long blade lengths, and the rigidity of the cutting tool is relatively long. Reduced, the strength and rigidity of the tool cannot meet the requirements, and the service life of the tool is short. In order to strengthen the strength and rigidity of the tool and enhance the service life of the tool, a short-edged strong milling cutter is designed to improve the rigidity and strength and ensure the precision of the mold. , the mold is processed in place at one time. When machining the hole of the workpiece, the hole is generally rough-machined first, then the hole is finished, and finally the chamfer is performed through the inlet end of the hole. Such a processing method requires the use of Three kinds of tools need to be clamped three times, the clamping time is longer and the efficiency is low; at the same time, after three times of clamping, there will be positioning errors and the machining accuracy will decrease

[0003] Therefore, an internally cooled tungsten steel milling cutter fixture is needed to meet the current market demand. Although a variety of milling cutter fixtures have been produced on the market, in general, there are still many common problems. One, the existing milling cutter fixture is not equipped with an adapter ring, which makes it impossible to replace the connecting rod according to the site conditions, causing certain inconvenience. Second, the clamping part of the existing milling cutter fixture is not locked by screwing the nut , but welding is used to fix it, which makes it inconvenient to replace the milling cutter in the later stage. Third, the top of the existing milling cutter fixture is not provided with a bayonet, which makes it impossible to quickly connect and fix the milling cutter fixture with external components
