Background technology
At present, in the time that fixture repeats to install machine, can only operate by rule of thumb by fixture engineer, first roughly fixture is contained on lathe by visual method, the method of then beating table centering with dial gauge is by chucking position centering position, expend time in longer, and after each fixture has been located, product working origin position can be inconsistent, so that CNC debugging process time long (at every turn adjust machine need to from new correction origin position), procedure need to be revised repeatedly, add that detection time is long, all cause Quick Changeover putting into production, product quality can not get effective guarantee, reduce production efficiency, normal delivery target date that even can delay product.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of clamp structure, can realize Quick Changeover, enhances productivity.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of clamp structure, for clamping product, described clamp structure comprises clamp bottom board, clamp supporting plate, location-plate, clamp supporting plate is arranged on clamp bottom board, and described location-plate is arranged on clamp supporting plate, described location-plate clamping product, described product has product benchmark point, described clamp structure is connected with machine tool guideway working face while use, and described machine tool guideway working face is provided with keyway
On described clamp bottom board, offer fixture centering initial point hole, X between described fixture centering initial point hole and product benchmark point is Mcm to distance, Y-direction distance between described fixture centering initial point hole and product benchmark point is Ncm, M, N are positive integer, and the upper surface of described clamp bottom board is inscribed the coordinate that has fixture centering initial point hole;
On described clamp bottom board, be also provided with two rough positioning devices, described each rough positioning device protrudes from the lower surface of clamp bottom board and can match with keyway.
Preferably, each rough positioning device described in the utility model is latch or feather key.
Preferably, the internal diameter in fixture centering initial point described in the utility model hole is 9.982 ~ 10.018mm, and the degree of depth in described fixture centering initial point hole is 6 ~ 10mm.
Further, the utility model also comprises alignment pin, and in described clamp structure, the junction of interconnective every adjacent two parts offers locating hole, locating hole and alignment pin interference fit.
The utility model operation principle is as follows:
New fixture debugs first and examination adds man-hour: obtain after qualified products, on clamp bottom board, select certain position and carve product benchmark to put the position dimension of fixture centering initial point, process herein fixture centering initial point hole, the pore size in this hole can be determined by the actual conditions of fixture, then by the actual coordinate X-Y of fixture centering initial point, be scribed at clamp bottom board upper surface; Reinstall next time after fixture, find this fixture centering initial point accurately and calibrate after the initial point numeral of CNC program, can obtain fast qualified product.
Try first after processing and debugging success, again when loading and unloading clamp:
First, default two rough positioning devices in the time of clamp bottom board, in the time reinstalling on fixture machine, these two rough positioning devices coordinate with the keyway of machine tool guideway working face, thereby substantially put positive fixture, and then utilize dial gauge centering fixture B benchmark (as shown in Figure 2) and CNC lathe X leading screw direction, can determine the directions X tram of fixture with this; Then, adopt CNC main shaft that centering rod is installed, find fast fixture centering initial point hole site, utilize the coordinate (being the coordinate dimension between product benchmark point and fixture centering initial point hole) of inscribing on clamp bottom board, determine the correct coordinates initial point of the program of tool sharpening product; Then, directly utilize and originally debugged successful CNC program, revise after its X-Y origin of coordinates data, directly start processing.
So, after centering, can put into production immediately, needn't be more repeatedly the report the test of verification examination converted products adjust knives routine or chucking position, repeat machine debug time thereby greatly saved, practice shows to save the time of 100%-400% left and right.
Therefore compared with prior art, the utility model has following beneficial effect:
In the time of sectional fixture again, can locate fast, fast aligning fixture tram, reach the optimum efficiency while successfully debugging exemplar first, can ensure to start fast, put into production, effectively improve production efficiency.With respect to other jig Design, the utility model possesses following advantage:
1, repeat to install machine when debugging and reach under the condition of same effect minimum shortening 40% of set-up time at fixture.
2, repeat after installation at fixture, start the minimum shortening 40% of time of producing from production debugging to obtaining qualified products.
3, repeat to be installed to startup at fixture and produce, improve production capacity more than 20% (calculated the same day that repeats to install with respect to fixture).
