Description
Technical field
The utility model relates to a kind of fixture, specifically a kind of machining center frock clamp.
Background technology
CNC milling machine is a kind of automatic processing device grown up on the basis of general milling machine, and both processing technologys are substantially identical, and also some is similar for structure.CNC milling machine has to be divided into is not with tool magazine and the large class of band tool magazine two.CNC milling machine wherein with tool magazine is also called machining center.At present, of the prior art for mostly relying on oil pressure to hold out against the mode of wedge locking auxiliary support bar all the time in the fixture of lathe, this kind of mode is with the fluctuation of oil pressure, and supplemental support pressure also can produce fluctuation, easily causes clamping failures; Mainly spring reset is relied in prior art, but due to the more difficult control of spring force, and spring in use easily follows the string, so rely on spring reset not to be very reliable.Present letter need have a kind of volume little, resets reliable, and can the fixture of reliable grip, and support workpiece that can be stable in process, ensures machining accuracy.
Summary of the invention
The purpose of this utility model is to provide a kind of machining center frock clamp, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of machining center frock clamp, comprise holder, block and vacuum cylinder, one end of described holder is provided with block, block comprises and the abutting part of feature contacts and connecting portion, connecting portion and abutting part are formed in one and arrange, this ensure that the structural strength of block, connecting portion is arranged on the two ends of abutting part, and connecting portion is vertical with abutting part to be arranged, described connecting portion is equipped with the securing member that can abut holder, securing member is trip bolt, and connecting portion arranges screwed hole, and trip bolt inserts connecting portion and trip bolt abuts holder, the sidewall of described holder is provided with binding groove, and securing member stretches in binding groove, the other end of described holder is provided with and is arranged with two hold down gags, hold down gag comprises main body, bonnet, pipe joint, one O RunddichtringO, 2nd O RunddichtringO, dovetail groove type wedge, 3rd O RunddichtringO, pilot bushing, protective cover, bulb support nail, auxiliary support bar and dust ring, described dovetail groove type wedge cooperation is arranged in the endoporus of main body, bonnet is arranged in the endoporus of main body one end, pipe joint is arranged on bonnet, and be connected with main body, the main body other end installs protective cover, pilot bushing is arranged on body side, the outer dovetail cooperation of auxiliary support bar bottom is arranged on the interior dovetail groove of dovetail groove type wedge, the cylindrical cooperation of auxiliary support bar is arranged on the endoporus of pilot bushing, bulb support nail is fixedly mounted on auxiliary support bar.
Further, in the groove of described dovetail groove type wedge, the 2nd O RunddichtringO and the 3rd O RunddichtringO are installed.
Further, in the groove of described bonnet, an O RunddichtringO is installed.
Further, in the groove of described pilot bushing, dust ring is installed.
Compared with prior art, under the utility model guarantees to drive the prerequisite of dovetail groove type wedge, make the strength of bulb support nail top tight workpiece less, workpiece can not be made to produce distortion, when workpiece carries out adding man-hour, if workpiece is applied to the larger power of bulb support nail one, due to the effect of Self-locking angle, auxiliary support bar also can not produce displacement, guarantees hold out against all the time and support workpiece, prevents the generation of cutting vibrations.
