The utility model relates to a kind of clamping device, and particularly a kind of lathe is mainly used in the occasion that a plurality of workpiece are fixedly clamped simultaneously with multi-work piece Flexible Fixturing device.
Background technology
In the Metal Cutting Machine Tool, at workbench fixedly during clamping workpiece, usually use pressing plate and bolt that Workpiece clamping is fixed, the nut of bolt one end is positioned at the T-slot on the workbench, pressing plate is pressed on the workpiece of workbench top, but pressing plate one side pressure is on workpiece, and opposite side is pressed on the cushion block, by the nuts and bolt clamping work pieces.This mode clamping work pieces has randomness, causes Workpiece Machining Accuracy on the low side, needs to be equipped with the clamp fixer of a large amount of different specification sizes, troublesome poeration, and inefficiency can not adapt to the needs that production line formula continuous batch is produced.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, easy to operate, simultaneously a plurality of workpiece of clamping, time saving and energy saving lathe overcome the deficiencies in the prior art with multi-work piece Flexible Fixturing device.
Lathe of the present utility model multi-work piece Flexible Fixturing device, comprise clamp body, at clamp body rotary oil cylinder is installed, rotary oil cylinder connects pressure arm, at least two of described rotary oil cylinders are also arranged in a straight line on clamp body, on clamp body, by supporting seat pull bar is installed, pull bar is consistent with the orientation of rotary oil cylinder, piston rod in pull bar and the pull bar oil cylinder joins, the pull bar oil cylinder is fixedly connected on the clamp body, be set with at least two contiguous blocks on the pull bar, be respectively equipped with right plate and the right baffle-plate of working as on two lateral bracing struts of contiguous block, pull bar is set with spring between right baffle-plate and contiguous block, each contiguous block all is connected with saddle, for being slidingly connected, there is the workpiece centre locating piece saddle top, is fixed with locating dowel and workpiece support piece at clamp body between saddle and the clamp body.
Lathe of the present utility model multi-work piece Flexible Fixturing device, wherein said pull bar is positioned at the below on plane on the clamp body, and clamp body is provided with the hole, and described contiguous block protrudes upward from the hole and joins with described saddle.
Lathe of the present utility model is with multi-work piece Flexible Fixturing device, and being slidingly connected between wherein said saddle and the clamp body is slidingly connected for dovetail groove type.
Lathe of the present utility model multi-work piece Flexible Fixturing device, during use, each workpiece places on the workpiece support piece, driving pull bar by fluid pressure drive device moves axially, spring top moves by contiguous block, makes saddle and workpiece centre locating piece and workpiece thereupon mobile and lean against on the locating dowel, because the adjusting of spring force being arranged, each workpiece is leaned against on the locating dowel simultaneously, then drive pressure arm with Work-sheet pressing by rotary oil cylinder.A plurality of workpiece can be located simultaneously, and accurately and reliably, clamping force is even, improve the machining accuracy of workpiece, are suitable for the needs of production line beat.Simple in structure, easy to operate, time saving and energy saving.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is schematic top plan view shown in Figure 1;
Fig. 3 is that schematic diagram is looked on a left side shown in Figure 1;
Fig. 4 is the local enlarged diagram of I section shown in Figure 1.
The specific embodiment
Shown in Fig. 1,2,3,4: 1 is clamp body, the rotary oil cylinder 7 that joins with hydraulic control device is installed at clamp body 1, the quantity of rotary oil cylinder 7 is 6 and arranged in a straight line on clamp body 1, each rotary oil cylinder 7 connects a pressure arm 8, the pressure arm 8 that turns oil cylinder 7 connections that is positioned at two ends is single armed, the pressure arm 8 that rotary oil cylinder 7 in the middle of being positioned at connects is both arms, and namely the both sides pressure arm is symmetrical arranged.By supporting seat 4 pull bar 5 is installed on clamp body 1, supporting seat 4 is fixedly connected on the clamp body 1, is provided with axle sleeve between supporting seat 4 and pull bar 5, is convenient to moving axially of pull bar 5.Pull bar 5 is consistent with the orientation of rotary oil cylinder 7.
Piston rod in the right-hand member of pull bar 5 and the pull bar oil cylinder 6 joins, concrete connected mode is that the right-hand member at pull bar 5 is processed with notch, the nut 12 of connecting bolt 11 terminations is positioned at notch, and connecting bolt 11 is threaded with piston rod end in the pull bar oil cylinder 6, and tightens fixing with nut 10.Pull bar 5 can be many and join end to end and connect the mode that can adopt pull bar 5 right-hand members to be connected with piston rod during connection.
Pull bar oil cylinder 6 is bolted to connection on clamp body 1.
Be set with 6 contiguous blocks 3 on the pull bar 5, be respectively equipped with right when plate 13 and right baffle-plate 15 on two lateral bracing struts 5 of each contiguous block 3, pull bar 5 is set with spring 14 between right baffle-plate 15 and contiguous block 3, each contiguous block 3 all is connected with saddle 2, for being slidingly connected, this is slidingly connected as dovetail groove type is slidingly connected between saddle 2 and the clamp body 1, and pull bar 5 is positioned at the below on plane on the clamp body 1, clamp body 1 is provided with hole 19, contiguous block 3 from the hole 19 protrude upward and with saddle 2 join (referring to Fig. 3).Saddle 2 tops have been bolted to connection workpiece centre locating piece 16.A side that is positioned at each rotary oil cylinder 7 at clamp body 1 is fixed with locating dowel 18 and workpiece support piece 17.
