Abstract
The invention relates to a vertical lathe toolholder clamping structure which comprises a hydraulic cylinder, a thread bushing, bolts, a belleville spring, a ram, a draw bar, a drag hook, a shank, a positioning block and a toolholder. The hydraulic cylinder is fixed on the ram through bolts; the belleville spring is installed on the draw bar; the thread bushing is screwed down on the upper end of the draw bar; the draw bar and the drag hook are respectively installed in a ram hole; the shank is installed in a taper hole of the ram; the positioning block is installed at the lower end of the ram and is used for positioning; the toolholder is installed on the shank through bolts. According to the invention, the draw bar draws the drag hook under the action of the belleville spring, and the drag hook pulls the handle part of the shank to lock the toolholder. The vertical lathe toolholder clamping structure changes the mounting manner of the toolholder. By adopting hydraulic control manner, the vertical lathe toolholder clamping structure can realize the speedy replacement and positioning of the toolholder, and the vertical lathe toolholder clamping structure reduces repeated positioning and can effectively improve the working efficiency.
Description
Technical field
The present invention relates to a kind of removable holder structure, especially a kind of vertical lathe removable holder structure.
Background technology
In vertical lathe industry process, the quick-replaceable of cutter holder, can increase work efficiency in the location fast.Wherein, holder structure is a kind of clamp-on tool structure commonly used, also is a kind of important structure of clamp-on tool in the vertical lathe.In the use procedure of cutter clamping structure, installation way has determined operating efficiency, in numerous factors that affect the cutter positioning, the cutter holder mounting means is very important one, before the present invention, the clamping of cutter holder adopts bolt directly to be fixed on the ram, in the high volume production process, tool wear, need to again change cutter, will reorientate after the replacing, in this process, cutter will be reorientated, and operating efficiency reduces.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of ingenious, rational a kind of vertical lathe cutter holder clamping structure is provided, this structural change the mounting means of cutter holder, adopt hydraulic control, can realize quick-replaceable and the location of cutter holder, effectively raise operating efficiency.
According to technical scheme provided by the invention: a kind of vertical lathe cutter holder clamping structure comprises hydraulic cylinder, thread bush, bolt, stacking spring, ram, pull bar, drag hook, handle of a knife, locating piece and cutter holder, described hydraulic cylinder is fixed by bolts on the ram, stacking spring is installed on the pull bar, on the pull bar thread bush being housed tightens, pull bar and drag hook are installed in respectively in the ram hole, handle of a knife is installed in the bellmouth of ram, locating piece is installed in the ram lower end, with the locating piece location, cutter holder is installed on the handle of a knife by bolt.
As a further improvement on the present invention, described pull bar contacts with drag hook.
The present invention compared with prior art, advantage is: described pull bar, under the effect of stacking spring elastic force, spur drag hook, drag hook pulling handle of a knife shank is realized locking, and locating piece is housed on the ram, position tool shanks usefulness reduces resetting, can increase work efficiency.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1, described a kind of vertical lathe cutter holder clamping structure comprises hydraulic cylinder 1, thread bush 2, bolt 3, stacking spring 4, ram 5, pull bar 6, drag hook 7, handle of a knife 8, locating piece 9, cutter holder 10.
The present invention adopts hydraulic cylinder 1 usefulness bolt 3 to be fixed on the ram 5, stacking spring 4 is installed on the pull bar 6, tighten with thread bush 2 upper end, pull bar 6 and drag hook 7 are installed in respectively in ram 5 holes, and be in contact with one another, locating piece 9 is installed in ram 5 lower ends, and handle of a knife 8 is installed in the bellmouth of ram 5, with locating piece 9 location, cutter holder 10 is installed on the handle of a knife 8.
The present invention spurs pull bar 6 by the elastic force effect of stacking spring 4, pull bar 6 pulling drag hooks 7, the shank of drag hook 7 pulling handle of a knifes 8, realize locking, under the effect of hydraulic cylinder 1, press down pull bar 6, drag hook 7 unclamps handle of a knife 8, realize the quick-replaceable cutter holder, in addition, locating piece 9 is equipped with in ram 5 lower ends, can avoid the resetting of cutter holder 10, and can increase work efficiency.
