Detailed description of the invention
Embodiment one
As shown in Figure 1-Figure 3, clamping device of the present utility model comprises push rod 1, clamping sleeve 2, handle 3, capping 4, clamp body 5, dog plate 7 and compact heap 8; Wherein, clamp body 5 is a cylinder, and its inside is fixed with dog plate 7, dog plate 7 is evenly provided with 3 movable jaws 6; The top of clamping sleeve 2 be positioned at clamp body 5 inner and with movable jaw 6 matched in clearance, the end of clamping sleeve 2 is connected to one end of clamp body 5 by capping 4, clamping sleeve 2 and capping 3 are threaded connection, and clamping sleeve 2 can enough around own axis; The top end face of clamping sleeve 2 is provided with the screw thread matched with movable jaw 5; Push rod 1 is in the horizontal direction successively through the sidewall of clamping sleeve 2, dog plate 7 and clamp body 5; The top of push rod 1 is threaded connection compact heap 8; Push rod 1 and clamping sleeve 2, clamp body 5 all matched in clearance;
One end be positioned at outside clamp body 5 of clamping sleeve 2 is fixed with handle 3 by screw thread, and handle 3 rotates for driving clamping sleeve 2.When clamping sleeve 2 rotates, its top flank makes movable jaw 6 threadingly close until gripping push rods 1 to clamping sleeve 2 axle center place gradually, realizes the clamping object that clamping part treats processing component.
Compact heap 8 and push rod 1 are threaded connection.
Need the process that utility model the utility model clamps workpiece to be processed:
Before actuating utility model works, push rod 1 can move freely forward backward; During actuating, operator promotes push rod 1, until workpiece to be processed compresses by the compact heap 8 on push rod 1 top.Rotating clockwise handle 3 drives clamping sleeve 2 to rotate; Three claws 6, under clamping sleeve 2 rotates, to central motion on the guide rail of dog plate 7, contact push rods 1 up to three claws and are clamped.
This fixture can to workpiece Quick-clamped, and structural technique designing is desirable, is easy to self-locking, because clamping stroke is little, it is time saving and energy saving to use, can to the Workpiece clamping of different size.The Workpiece clamping of tubing to 0 < d < φ 150mm and different specification size can be realized.If clamp larger sized workpiece, suitably can strengthen the distance between clamp body 5 and clamping plate 9, the gripping range of clamping part of the present utility model can adapt to the clamping of most of cutting machine.
Clamping device of the present utility model can be applied to other cutting machine, lathes etc. needs clamp system mechanically.Below provide embodiment two.
Embodiment two
See Fig. 4, this gives a kind of structural representation applying device for cutting pipe of the present utility model.This device for cutting pipe comprises independently cutting part and clamping part, and namely clamping part adopts clamping device of the present utility model, and clamping device is positioned at the side of the cut workpiece of cutting part.
The structure of cutting part as shown in Figure 4, comprises base 9, footstock 10, motor 11, small pulley 12, V band 13, large belt wheel 14 and emery wheel 15; Wherein, footstock 10 is fixed on base 9 by pin, and footstock 10 can rotate around pin relative to base 9; Motor 11 is bolted on footstock 10, and motor 11 is connected with small pulley 12 interference fit by key; Small pulley 12 drives large belt wheel 14 by V band 13; Footstock 2 is provided with an axle by bearing, and axle can rotate relative to footstock 10; Large belt wheel 14 is fixed on one end of axle by key interference fit, emery wheel 15 is fixed on the other end of axle by reverse nut.
During work, motor 11 starts, and by key, small pulley 12 is passed in motion, and small pulley 12 drives large belt wheel 14 by V band 13, and large belt wheel 14 is rotated by key band moving axis, thus the emery wheel 15 of the band moving axis other end rotates.Operator makes it around pin relative to base rotation by pulling footstock 10, thus control emery wheel does the motion in vertical direction.
Emery wheel 15 corresponding position on base plate 9 is provided with a strip slot, and the width of this strip slot is greater than the thickness of emery wheel 15; Along with top board 10 rotates around pin, emery wheel 15 can move downwardly in strip slot.
The clamping plate 17 perpendicular to strip slot is provided with in strip slot side; Top board 9 between clamping part and clamping plate 17 is workpiece FX to be cut.
Optionally, footstock 10 arranges leader 16, make operator can pull footstock 10 easily like this and make it around pin relative to base rotation, the cutting movement that emery wheel 15 is done in vertical direction is more flexible.
Workpiece is placed on the top board between clamping device of the present utility model and clamping plate 17, inserts workpiece FX to be cut by it, promote push rod 1 until workpiece to be processed is pressed on pressure strip 9 by the compact heap 8 on its top; When cutting, clamping part is used to be fixed by workpiece, then actuating motor 11, by key, small pulley 12 is passed in motion, small pulley 12 drives large belt wheel 14 by V band 13, and large belt wheel 14 is rotated by key band moving axis, thus the emery wheel 15 of the band moving axis other end rotates.Operator makes it around pin relative to base rotation by pulling footstock 10, thus control emery wheel does the motion in vertical direction.
When changing workpiece after cutting completes, rotate counterclockwise handle 3 and unclamp clamping sleeve 2, make push rod 1 can free motion discharging workpieces backward.
