The clamp comprises a base, wherein the bottom surface of the base is a plane, the upper end of the base is provided with a concave cavity corresponding to a bulge arranged at the bottom of a workpiece, the two sides of the base are respectively provided with a workpiece clamp which can clamp the workpiece through being driven by a power machine, each workpiece clamp comprises a first clamping seat and a second clamping seat which are connected with a screw rod through screw threads, the second clamping seat is fixedly connected with the side wall of the base, a telescopic guide post is arranged between the first clamping seat and the second clamping seat, a locking screw is arranged on the telescopic guide post, the power machine is a motor, and one end of the screw thread is connected with an output shaft of the motor through a speed reducer. The gantry milling workpiece clamp can solve the problem that the workpiece provided with the bulge at the bottom surface cannot be processed by the gantry milling.

Description

Gantry mill work piece holder
Technical field
The present invention relates to technical field of tooling clamps, especially a kind of work piece holder for planer-type milling machine.
Background technology
Planer-type milling machine is called for short gantry mill, be the milling machine with portal frame and horizontal long lathe bed, planer-type milling machine includes portal frame, horizontal long lathe bed, and horizontal long lathe bed is added is provided with moveable workbench, add man-hour, trade union college on the table and with workbench do length feed motion; Although gantry mill can process various workpieces, the table top due to its workbench is plane, and therefore, gantry mill can only process the workpiece that bottom surface is plane, has protruding workpiece then cannot process for bottom surface.
Summary of the invention
Technical problem to be solved by this invention is to provide gantry mill work piece holder, and this fixture can solve the problem that bottom surface has protruding workpiece gantry mill to process.
In order to solve the problem, the technical solution adopted in the present invention is: this gantry mill work piece holder, include the base that its bottom surface is plane, the upper end of described base offers the cavity corresponding to workpiece bottom protrusion, and the both sides of described base are provided with the workpiece clamp driven by engine.
In technique scheme, technical scheme can also be more specifically: described workpiece clamp includes the first clamping seats and the second clamping seats that are threaded connection with screw rod, described second clamping seats is fixedly connected with described base side wall, be provided with flexible lead between described first clamping seats and described second clamping seats, described flexible lead is provided with lock bolt; Described engine is motor, and one end of described screw rod is connected with the output shaft of motor by decelerator.
Further: described base upper end is provided with pressure sensor, and described pressure sensor is electrically connected with described motor by frequency converter.
Further: described base to offer the counterbore be connected with gantry mill by bolt.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, cavity corresponding to workpiece bottom protrusion is offered owing to being provided with its upper end, its bottom surface is the base of plane, and the both sides of base are provided with the workpiece clamp being driven holding workpiece by engine, during work, base is fixed on the workbench of gantry mill, and by piece-holder on base, can process workpiece, clamping fastener and without movement; Not only protruding workpiece can be had to process to bottom surface, also improve machining accuracy.
2, because the first clamping seats of workpiece clamp and the second clamping seats and screw rod are threaded connection, be provided with flexible lead between the first clamping seats and the second clamping seats, flexible lead is provided with lock bolt; And one end of screw rod is connected with the output shaft of motor, during work, regulated the spacing of the first clamping seats and the second clamping seats by lead and lock bolt, drive screw rod to rotate forward, by Workpiece clamping when motor rotates forward; When completing, unclamp lock bolt, make motor reversal drive screw rod reversion that the distance between the first clamping seats and the second clamping seats is extended, workpiece can be taken out.
3, because base upper end is provided with pressure sensor, and pressure sensor is electrically connected with described motor by frequency converter, by the rotation of the pressure signal reed time controll motor of pressure sensor, reaches the effect of adjustment piece-holder power.
4, owing to base offering the counterbore be connected with gantry mill by bolt, base can be fixedly connected with gantry mill.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Gantry mill work piece holder shown in Fig. 1, include the base 4 that bottom surface is plane, the upper end of base 4 offers the cavity corresponding to workpiece 5 bottom protrusion, the both sides of base 4 are provided with the workpiece clamp 1 being driven holding workpiece 5 by engine, workpiece clamp 1 includes the first clamping seats 11 of being threaded connection with screw rod 12 and the second clamping seats 13, second clamping seats 13 is fixedly connected with the sidewall of base 4; Flexible lead 8 is provided with between first clamping seats 11 and the second clamping seats 13, first clamping seats 11 is fixedly connected with one end of flexible lead 8, second clamping seats 13 is fixedly connected with the other end of flexible lead 8, and flexible lead 8 is provided with lock bolt 81; Engine is motor 3, and one end of screw rod 12 is connected by the output shaft of decelerator 2 with motor 3; Base 4 upper end is provided with pressure sensor 6, and pressure sensor 6 is electrically connected with motor 3 by frequency converter; Base 4 offers the counterbore 7 be connected with gantry mill by bolt.
During work, first, base is placed in the workbench relevant position of gantry mill, in counterbore, puts into bolt base is fixed on the workbench of gantry mill; Be placed on base by workpiece correspondence again, regulate lead that the first clamping seats is crimped on workpiece, then locked by lock bolt, starter motor makes screw rod rotate forward Workpiece clamping, then, starts gantry mill and processes workpiece; In process, the pressure signal of pressure sensor controls the rotation of motor in real time by frequency converter, to adjust the chucking power of workpiece clamp to workpiece in real time, when processing is completed, unclamp screw lock, starter motor makes screw rod reverse, extend the distance between the first clamping seats and the second clamping seats, take out workpiece and get final product.
