Description

Lathe multi-work piece Flexible Fixturing device
Technical field
The present invention relates to a kind of clamping device, particularly a kind of lathe multi-work piece Flexible Fixturing device, is mainly used in the occasion be simultaneously fixedly clamped to multiple workpiece.
Background technology
In Metal Cutting Machine Tool, when fixing clamping workpiece on the table, Workpiece clamping is fixed by usual use pressing plate and bolt, the nut of bolt one end is positioned at the T-slot on workbench, pressing plate is pressed on the workpiece above workbench, can be pressed on workpiece in pressing plate side, opposite side be pressed on cushion block, by nuts and bolt clamping work pieces.This mode clamping work pieces has randomness, causes Workpiece Machining Accuracy on the low side, needs the clamp fixer being equipped with a large amount of different specification size, troublesome poeration, inefficiency, can not adapt to the needs that production line formula continuous batch is produced.
Summary of the invention
The object of this invention is to provide a kind of structure simple, easy to operate, can the simultaneously multiple workpiece of clamping, time saving and energy saving lathe multi-work piece Flexible Fixturing device, overcome the deficiencies in the prior art.
Lathe multi-work piece Flexible Fixturing device of the present invention, comprise clamp body, clamp body is provided with rotary oil cylinder, rotary oil cylinder connects pressure arm, described rotary oil cylinder at least two is also arranged in a straight line on clamp body, clamp body is provided with pull bar by supporting seat, pull bar is consistent with the orientation of rotary oil cylinder, pull bar connects with the piston rod in pull bar oil cylinder, pull bar oil cylinder is fixedly connected on clamp body, pull bar is set with at least two contiguous blocks, two lateral bracing struts of contiguous block are respectively equipped with right baffle plate and right baffle-plate, between right baffle-plate and contiguous block, pull bar is set with spring, each contiguous block is all connected with saddle, for being slidably connected between saddle and clamp body, workpiece centre locating piece is had above saddle, clamp body is fixed with locating dowel and workpiece support block.
Lathe multi-work piece Flexible Fixturing device of the present invention, wherein said pull bar is positioned at the below of plane on clamp body, and clamp body is provided with hole, and described contiguous block protrudes upward from hole and connects with described saddle.
Lathe multi-work piece Flexible Fixturing device of the present invention, being slidably connected as dovetail groove type is slidably connected between wherein said saddle and clamp body.
Lathe multi-work piece Flexible Fixturing device of the present invention, during use, each workpiece is placed on workpiece support block, pull bar is driven to move axially by fluid pressure drive device, spring top moves by contiguous block, makes saddle and workpiece centre locating piece and workpiece move thereupon and lean against in locating dowel, owing to there being the adjustment of spring force, each workpiece is leaned against in locating dowel simultaneously, then drives pressure arm by Work-sheet pressing by rotary oil cylinder.Multiple workpiece can be located simultaneously, and accurately and reliably, clamping force is even, improves the machining accuracy of workpiece, is suitable for the needs of production line beat.Structure is simple, easy to operate, time saving and energy saving.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention;
Fig. 2 is the schematic top plan view shown in Fig. 1;
Fig. 3 is that schematic diagram is looked on the left side shown in Fig. 1;
Fig. 4 is the I portion close-up schematic view shown in Fig. 1.
Detailed description of the invention
As shown in Figure 1,2,3, 4: 1 is clamp body, clamp body 1 is provided with the rotary oil cylinder 7 connected with hydraulic control device, 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 turning oil cylinder 7 connection being positioned at two ends is single armed, the pressure arm 8 being positioned at middle rotary oil cylinder 7 connection is both arms, and namely both sides pressure arm is symmetrical arranged.Clamp body 1 is provided with pull bar 5 by supporting seat 4, and supporting seat 4 is fixedly connected on clamp body 1, between supporting seat 4 and pull bar 5, be provided with axle sleeve, is convenient to moving axially of pull bar 5.Pull bar 5 is consistent with the orientation of rotary oil cylinder 7.
The right-hand member of pull bar 5 connects with the piston rod in pull bar oil cylinder 6, concrete connected mode is processed with notch at the right-hand member of pull bar 5, the nut 12 of connecting bolt 11 termination is positioned at notch, and connecting bolt 11 is threaded with the piston rod end in pull bar oil cylinder 6, and tightens fixing with nut 10.Pull bar 5 can be many and joins end to end and connects, and can adopt the mode that pull bar 5 right-hand member is connected with piston rod during connection.
Pull bar oil cylinder 6 is bolted to connection on clamp body 1.
Pull bar 5 is set with 6 contiguous blocks 3, two lateral bracing struts 5 of each contiguous block 3 are respectively equipped with right baffle plate 13 and right baffle-plate 15, between right baffle-plate 15 and contiguous block 3, pull bar 5 is set with spring 14, each contiguous block 3 is all connected with saddle 2, for being slidably connected between saddle 2 and clamp body 1, this is slidably connected as dovetail groove type is slidably connected, and pull bar 5 is positioned at the below of plane on clamp body 1, clamp body 1 is provided with hole 19, and contiguous block 3 protrudes upward from hole 19 and connects (referring to Fig. 3) with saddle 2.Workpiece centre locating piece 16 has been bolted to connection above saddle 2.The side that clamp body 1 is positioned at each rotary oil cylinder 7 is fixed with locating dowel 18 and workpiece support block 17.
During use, each workpiece 9 is placed on workpiece support block 17, pull bar 5 is driven to move axially by fluid pressure drive device, spring 14 leans contiguous block 3 and moves, saddle 2 is made to move thereupon with workpiece centre locating piece 16 and workpiece 9 and lean against in locating dowel 18, owing to there being the adjustment of spring 14 elastic force, making each workpiece 9 lean against in locating dowel 18 simultaneously, then drive pressure arm 8 to be compressed by workpiece 9 by rotary oil cylinder 7.Multiple workpiece can be located simultaneously, and accurately and reliably, clamping force is even, improves the machining accuracy of workpiece, is suitable for the needs of production line beat.Structure is simple, easy to operate, time saving and energy saving.
