The utility model has the beneficial effects that with the adoption of the eccentric device for locating and clamping workpieces, the processing efficiency of parts is improved by 60-70%; as clamping is finished in an eccentric manner, the work intensity of operators is greatly reduced.
Description
Technical field
The utility model belongs to machined, relates in particular to a kind ofly to be applied to surface grinding machine or the Cutter Body Processing with Machining Center precision is higher, the eccentric positioning clamping device of big part in batches.
Background technology
Surface grinding machine or Cutter Body Processing with Machining Center part adopt the location clamping mode of pressing plate usually.Though this locate mode can satisfy the process technology requirement.But when the deficiency that exists is (1) work in-process heart processing single-piece, changes a cutter and only process a part, efficient is lower, the clamping unbalance stress of (2) workpiece, and the clamping of uneven (3) workpiece in the location of workpiece, the time of unclamping extend, and efficient is lower, and labour intensity increases.Because said situation is at the machining industry ubiquity, so the bottleneck technical problem that the restriction that needs to be resolved hurrily is produced in enormous quantities.
The utility model content
The utility model is in order to overcome deficiency of the prior art; A kind of eccentric positioning clamping device is provided; Be suitable for the part that machining accuracy is high on surface grinding machine or machining center, batch is big, can raise the efficiency, reduce labor intensity, make the ratio of effective process time and secondary process time big.The utility model is for realizing above-mentioned purpose; Realize that through following technical scheme a kind of eccentric positioning clamping device is characterized in that: mainly constitute by pedestal and the base plate affixed and 4 hold-down mechanisms forming by location-plate, four block pressur plates, pressing plate shaft and pressing plate cover and eccentric stiffener with it; Said base plate one side is along its vertical affixed location-plate; Said pressing plate vertically is connected with pressing plate shaft through location-plate, and pressing plate shaft passes sleeve and its matched in clearance, and eccentric shaft vertically is put in adjustment plate below; Eccentric shaft is connected with taper knob through pin, and handle is connected with taper knob.
Said eccentric stiffener both sides are provided with the eccentric shaft locating piece affixed with the base plate sidewall.
Be connected back-moving spring with the location-plate sidewall on the said pressing plate.
The corresponding location-plate of said base plate upper surface is provided with the alignment pin of retaining element.
Beneficial effect: after adopting above-mentioned eccentric frock to workpiece location, clamping, the working (machining) efficiency of part has improved 60%-70%; Lean on eccentric the completion owing to clamp, alleviated operator's labour intensity greatly.
Description of drawings

Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1, pedestal 2, base plate 3, location-plate 4, pressing plate 5, pressing plate shaft 6, pressing plate cover 7, eccentric shaft 8, handle 9, taper knob 10, adjustment plate 11,12, eccentric shaft locating piece 13, back-moving spring 14, block 15, soket head cap screw 16, alignment pin
The specific embodiment
Below in conjunction with preferred embodiment; Details are as follows to the specific embodiment that provides according to the utility model: see accompanying drawing for details, a kind of eccentric positioning clamping device, mainly by pedestal 1 and with its with the fastening base plate 2 of soket head cap screw 15 and by location-plate 3, four block pressur plates 4, pressing plate shaft 5 and pressing plate overlap 6 and 4 hold-down mechanisms forming of eccentric stiffener constitute; Said base plate one side is along its vertical affixed location-plate; Said pressing plate vertically is connected with pressing plate shaft through location-plate, and pressing plate shaft passes sleeve and its matched in clearance, and eccentric shaft vertically is put in adjustment plate below; Eccentric shaft is connected with taper knob through pin; Handle is connected with taper knob, makes the adjustment plate depress sleeve thereby turning handle drives the eccentric shaft rotation, thereby clamps part.Said eccentric stiffener both sides are provided with the eccentric shaft locating piece 11,12 affixed with the base plate sidewall.Be connected back-moving spring 13 with the location-plate sidewall on the pressing plate, the back-moving spring top is provided with block 14.The corresponding location-plate of said base plate upper surface is provided with the alignment pin 16 of retaining element.The handle 8 of said eccentric stiffener connects with taper knob 9 usefulness screw buckles.Taper knob 9 is connected through alignment pin 16 with eccentric shaft 7, eccentric shaft and adjustment plate 10 matched in clearance, and pressing plate 4 vertical process location-plates 3 are connected with pressing plate shaft.
The course of work:
(1) spring is in flick the lock state,
(2) workpiece is packed in the alignment pin,
(3) pull handle, the motion of eccentric adjustment plate is pressed guarantee that 4 whiles are stressed, workpiece is all clamped thereby drive presser motion;
(4) start process equipment and process,
(5) completion of processing;
(6) spanner handle unclamps pressing plate under spring action;
(7) take out the workpiece that processes;
(8) the pressing plate purge is clean, prepare next circulation.
According to the appearance and size of workpiece, the length of the complicated and simple and process time of operation can be amplified location-plate, loads onto several bodies, to obtain high working (machining) efficiency.
Use handle, it is more laborsaving easy that workpiece is installed, and four points of eccentric effect position is stressed even.Adopt back-moving spring that briquetting is resetted, make tool structure simplify.Device body is an elementary cell, and several device bodies are installed on a base plate, according to most effective principle, use wherein partly or entirely.
The above only is the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
