Abstract
The invention relates to an eccentric clamping fixture which is characterized by comprising a fixture body, a front pressure plate seat, a rear pressure plate seat, a bottom plate, pressure plates, eccentric circular handles, draw bars, positioning pins and positioning plates. The fixture body, the front pressure plate seat and the rear pressure plate seat are respectively fixedly connected with the bottom plate, the fixture body is arranged between the front pressure plate seat and the rear pressure plate seat, eccentric compressing mechanisms are arranged on the front pressure plate seat and the rear pressure plate seat respectively and comprise the pressure plates, the eccentric circular handles, the draw bars, the positioning pins and the positioning plates, the pressure plates are respectively in pin joint with the front pressure plate seat and the rear pressure plate seat by dowels, the positioning pins and the positioning plates are fixed onto the fixture body, the draw bars penetrate through upper portions of the front pressure plate and the rear pressure plate, each cylindrical pin is radially inserted into one end of the corresponding draw bar, and each eccentric circular handle is in pin joint with the other end of the corresponding draw bar. The eccentric clamping fixture has the advantages that when the eccentric clamping tool is used for machining a part, required part assembling and disassembling duration in a part machining process is greatly shortened as compared with the traditional tool, the average duration is shortened to be 25% of the original part assembling and disassembling duration, and the machining efficiency is obviously improved.
Description
Technical field
The invention belongs to the anchor clamps of machining, relate in particular to a kind of eccentric clamping fixture.
Background technology
Often adopt the screw pressing plate to clamp during the processing equipment part, although this locate mode is simple, Shortcomings: the mode that tradition is fixed by the screw pressing plate, twist screw during workpiece loading and unloading and lose time, cause working (machining) efficiency not high.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, and a kind of eccentric clamping fixture that can Quick-clamped unclamps fast is provided, and eccentric cam band Self-locking angle is realized clamping, about pressing plate can be realized when compression is unclamped and up and down both direction motion.
The present invention for achieving the above object, be achieved through the following technical solutions, a kind of eccentric clamping fixture, it is characterized in that: comprise chuck body, front and back pressing plate seat, base plate, pressing plate, the off-centre operation handle, pull bar, alignment pin and location-plate, described chuck body and front and back pressing plate seat are affixed with base plate respectively, described chuck body places between the pressing plate seat of front and back, described front and back pressing plate seat is provided with eccentric compacting mechanism, described eccentric compacting mechanism comprises pressing plate, the off-centre operation handle, pull bar, alignment pin and location-plate, be connected with respectively pressing plate by pin on the pressing plate seat of described front and back, be fixed with alignment pin and location-plate on the described chuck body, pull bar is run through on pressing plate top, described front and back, the pull bar one end straight pin of radially pegging graft, its other end is connected with the off-centre operation handle.
Be set with spring on the described pull bar.
Affixed 1-4 group eccentric compacting mechanism on the described base plate.
Beneficial effect: adopt above-mentioned eccentric clamping frock processing parts, loading and unloading part required time has had very large shortening than front traditional frock in the processing parts, is reduced to average time originally 25%, has significantly improved working (machining) efficiency.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the top view of Fig. 2.
Among the figure: 1, base plate 2, front and back pressing plate seat 3, straight pin 4, pull bar 5, spring 6, pressing plate 7, alignment pin 8, location-plate 9,10, off-centre operation handle 11, split pin 12, chuck body
The specific embodiment
Below in conjunction with preferred embodiment, to details are as follows according to the specific embodiment provided by the invention: see accompanying drawing for details, a kind of eccentric clamping fixture, comprise chuck body 12, front and back pressing plate seat 2, base plate 1, pressing plate 6, off-centre operation handle 9,10, pull bar 4, alignment pin 7 and location-plate 8, described chuck body and front and back pressing plate seat are affixed with base plate respectively, described chuck body places between the pressing plate seat of front and back, described front and back pressing plate seat is provided with eccentric compacting mechanism, described eccentric compacting mechanism comprises pressing plate, the off-centre operation handle, pull bar, alignment pin and location-plate, be connected with respectively pressing plate by pin on the pressing plate seat of described front and back, be fixed with alignment pin and location-plate on the described chuck body, pull bar is run through on pressing plate top, described front and back, the pull bar one end straight pin 3 of radially pegging graft, its other end is connected with the off-centre operation handle.Be set with spring 5 on the described pull bar.Affixed 1-4 group eccentric compacting mechanism on the described base plate.Be equipped with split pin 11 on the straight pin.Operation principle
With a frock parts by the assembling of above-mentioned annexation after, workpiece is installed on the location-plate by the alignment pin guarantor to size, add and man-hour base plate is fixed on the lathe with bolt, pull spanner downwards by the cam driven pull bar, thereby the band dynamic pressure plate is realized can realizing the clamping of workpiece to center and simultaneously motion downwards, upwards pull spanner pull bar and pressing plate counter motion, can realize unclamping of workpiece, thereby realize the quick loading and unloading of workpiece, enhance productivity.
The course of work
(1) workpiece is fixed on the location-plate by the pin direction
(2) pull the chucking action that spanner is realized workpiece downwards
(3) processing parts
(4) upwards pull spanner and realize unclamping of workpiece, unload workpiece and finish processing.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment does.
