Technical field
The utility model is related to a kind of clamping device, more particularly to a kind of square cross clamping device.
Background technology
Fixture or clamping device are that its effect is by work to clamping workpiece and a kind of device of guiding cutter on lathe Part is positioned, so that workpiece obtains the correct position relative to lathe and cutter, and workpiece is reliably clamped.Square cross Four faces of its in clamping process are required to clamp stress.Size, specification in view of square cross exist in actual production to be become It is used for clamping the clamping device of above-mentioned square cross on amount, lathe, its structure just includes a pair of fixed stops and one substantially To movable clamping block.But, the clamping device of above-mentioned existing square cross, a pair of movable clamping blocks in its structure need independent , there is the relatively slow situation of Workpiece clamping, have a strong impact on the processing efficiency of lathe in debugging.
For problem above, Application No. CN201610511839.0 patent document discloses a kind of folder of square cross Tight device, includes the fixed stop of a pair of vertical mutually arrangements on same mounting plane, wherein the fixed gear of one The right opposite of block is provided with guide pad, and forms a piece-holder position between the two, and the guide pad is provided with oblique spigot surface, and Direction towards above-mentioned piece-holder position tilts extension, and the right opposite of another the fixed stop is provided with air cylinder group wherein Connecting rod is movably hinged with part, the cylinder rod of the cylinder assembly, and both hinged places are located on the middle section position of connecting rod, institute State and wedge is movably hinged with a side end of connecting rod, the wedge surface of the wedge faces above-mentioned oblique spigot surface, and above-mentioned Oblique spigot surface fall stretching back and forth on track in wedge, the end side of the connecting rod is by one all the time in being drawn The extension spring of state is stretched mutually to fix with the cylinder block in cylinder assembly, and on the above-mentioned connecting rod of the side provided with can vertical top it is upward State the adjustable hold-down gear of piece-holder position;The cylinder rod of the cylinder assembly passes through constantly whole so as to drive toward overhanging Connecting rod is moved to piece-holder position direction, under the collective effect of wedge and adjustable hold-down gear, by square cross most final pressure Fixed stop position is tightened to, the clamping and positioning of whole workpiece is realized;The adjustable hold-down gear includes nut and screw rod, wherein spiral shell Mother is fixed on above-mentioned connecting rod, and a side end of screw rod, which is screwed in, runs through above-mentioned connecting rod after nut.
Said apparatus solves the relatively slow problem of Workpiece clamping, but this device has the following disadvantages:Square shaped work During part is clamped, manual adjusting screw rod is needed, carrys out square shaped workpiece and is clamped, its troublesome poeration, and then have impact on The efficiency of clamping, reduces the processing efficiency of lathe.
Utility model content
The utility model is intended to provide a kind of simple to operate, square cross clamping device of high working efficiency.
It is elasticly connected with square cross clamping device in this programme, including frame, the frame in V-block, V-block Air bag is mutually had, air bag is provided with air inlet pipe, and V-block is connected with upper fixture block, and upper fixture block is slidably connected in frame, upper fixture block phase The first tooth bar is connected with, the first tooth bar is engaged with gear, and gear is engaged with the second tooth bar, and the second tooth bar is slidably connected in frame, Second tooth bar is provided with connecting rod, connecting rod and is rotatably connected with roller, and roller mutually has voussoir, and one end of voussoir is connected with right folder Block, the other end elastic connection of voussoir is additionally provided with left fixture block and lower fixture block in frame in the frame, the lower fixture block is slided It is connected in frame, lower fixture block is connected with the second tooth bar.
The know-why of this programme is:Frame provides support for whole device;Air bag is to be passed through gas from air inlet pipe Body, air bag expansion, air bag promotes V-block to be moved to close to lower fixture block direction;V-block is connected with upper fixture block, and upper fixture block, which is slided, to be connected It is connected in frame, drives upper fixture block to be moved to close to lower fixture block direction while V-block is moved;Upper fixture block is connected with the first tooth Bar, upper fixture block movement drives the first tooth bar to be moved to close to lower fixture block direction;First tooth bar is engaged with gear, the first rack drives Pinion rotation;Gear is engaged with the second tooth bar, and the second tooth bar is slidably connected in frame, and the second tooth bar is to away from lower fixture block direction Motion;Lower fixture block is slidably connected in frame, and lower fixture block is connected with the second tooth bar, and the second rack drives lower fixture block is to close to upper folder Block direction is moved, and the distance between lower fixture block and upper fixture block shorten;The above and below of square shaped workpiece is clamped;Second tooth bar It is provided with connecting rod, connecting rod and is rotatably connected with roller, roller mutually has voussoir, the second tooth bar is moved to away from lower fixture block direction While, drive roller stress on the wedge surface of voussoir to roll;One end of voussoir is connected with right fixture block, the other end elasticity of voussoir It is connected in frame, roller promotes right fixture block, and fixture block direction is moved to the left, and the distance between left fixture block and right fixture block shortens, square shaped The left and right face of workpiece is clamped;Then square shaped workpiece is processed.
This programme has the beneficial effect that:1st, by being expanded after airbag aeration, while being upper fixture block, lower fixture block and right folder Block square shaped Workpiece clamping provides power, the resource of energy is fully utilized, while square shaped workpiece is pressed from both sides Tightly, operating efficiency is improved, it is to avoid the efficiency of influence machine tooling.
Further, the lower fixture block includes hollow block, and slip cap is connected to movable block in hollow block, by movable block hollow Slided in block, form flexible lower fixture block, square shaped workpiece is clamped work.
Further, second tooth bar is connected with movable block.Moved reciprocatingly by the second tooth bar, drive movable block in Slided in empty block, be the flexible offer power of lower plate.
Further, second tooth bar slidably connects slide rail, and slide rail is fixedly mounted in frame.Slide rail is the second tooth bar Movement locus is provided, and slide rail also acts the effect of the second tooth bar of support.
Further, it is equipped with block rubber on the bare terminal end of the upper fixture block, lower fixture block, left fixture block and right fixture block.Block rubber The friction between upper fixture block, lower fixture block, left fixture block, right fixture block and square cross can be increased, strengthens the effect clamped, keeps away simultaneously Exempt from upper fixture block, lower fixture block, left fixture block, the clamping face of right fixture block square shaped workpiece to cause to damage.
Further, the right fixture block is slidably connected in frame.Frame plays a part of support first to right fixture block, secondly Right fixture block is slided in frame, reduces the resistance in right fixture block progress square cross clamping process.
