Abstract
The utility model relates to a universal clamp for processing a case-body-like workpiece. The universal clamp is characterized in that regularly arranged mounting grooves are distributed on the surface of a clamp body; positioning pin holes and fixing bolt holes are distributed at intervals at the bottom of the mounting grooves; a locating block, a locking block and a cover plate are distributed inside each of the mounting grooves; and the upper end surface of the locking block is connected with the pressure plate. When the case-body-like workpiece is processed, the distribution positions of the locating blocks and the locking blocks on the clamp body are defined at first according to the positions of positioning holes of a part to be processed, then the clamp body is fixed and aligned, and the positioning holes of the part to be processed are aligned to the positioning pins on the locating blocks; and at last, a pressure plate is mounted on the upper surfaces of the locking blocks, and the part to be processed is clamped. Therefore, when different products to be processed are replaced, only the positioning pins and the pressure plate positions rather than other clamp components need to be replaced, thereby enabling the clamp to adapt to different product processing rapidly, shortening the time for preparation of production, and saving the resources.

The specific embodiment
The universal fixturing of the machining box-type workpieces shown in Fig. 1～11, its special feature is: comprise clamp body 1, described chuck body 1 surface distributed has by the certain size rule carries out regularly arranged mounting groove 2.For the ease of plugging into of multimode, mounting groove 2 bottom lands are intervally distributed with dowel hole 3 and fixed bolt hole 4, make to be distributed with locating piece 5, latch segment 6, cover plate 7 in the mounting groove 2.And, consider the impact-resistant ability of parts, locating piece 5, latch segment 6, cover plate 7 all adopt the manufacturing of S45C material.
Simultaneously, the upper surface of latch segment 6 connects pressing plate 8, is used for fastening part to be processed 14.Certainly, consider that the outline of part to be processed 14 is varied, be provided with bolt 9, the controlled clamping degree of neutralizing 8 pairs of parts to be processed 14 of plate of regulating in the pressing plate 8.
Further combined with Fig. 3, Fig. 4, described locating piece 5 upper surfaces are provided with the alignment pin 10 that matches with locating hole 13 on the part to be processed 14, with this come with workpiece to be machined on locating hole 13 cooperate usefulness.Simultaneously, locating piece 5 bottom surfaces are distributed with alignment pin 10 and secondary bolt hole 11, and alignment pin 10 is corresponding with dowel hole 3 positions, and secondary bolt hole 11 is corresponding with fixed bolt hole 4 positions.
Same, being provided with the kingbolt hole 12 that is used for connecting pressing plate 8 bolts at latch segment 6 upper surfaces, latch segment 6 bottom surfaces are distributed with alignment pin 10 and secondary bolt hole 11, and alignment pin 10 is corresponding with dowel hole 3 positions, and secondary bolt hole 11 is corresponding with fixed bolt hole 4 positions.
In conjunction with Fig. 7, Fig. 8, cover plate 7 upper surfaces are smooth flat, and cover plate 7 bottom surfaces are distributed with secondary bolt hole 11, and secondary bolt hole 11 is corresponding with fixed bolt hole 4 positions.And the thickness of cover plate 7 is consistent with mounting groove 2 appropriateness.Like this, in use cover untapped mounting groove 2, can effectively prevent the accumulation of smear metal by cover plate 7.
Concrete occupation mode in conjunction with the universal fixturing of this machining box-type workpieces: part to be processed 14 is a casing, and part to be processed 14 bottom surfaces are a plane, has 8 of two positioning process holes and pressing plates.
At first, the technical staff can utilize softwares such as CAD, determine the correct position of part on jig plate, determine promptly how mounting groove 2 positions below part locating hole 13 need assemble Distribution and localization piece 5 latch segments 6, also determined the position dimension of alignment pin 10 on the locating piece 5 simultaneously.
Then, be assembled to the tram according at least two corresponding locating pieces 5 of the above data decimation that draws.With four latch segments 6 be assembled to 8 of part pressing plates under mounting groove 2 in.Make the bottom surface of locating piece 5 or latch segment 6 fit to 2 ends of mounting groove as long as alignment pin 10 nails are aimed at the locating hole 13 at 2 ends of mounting groove during assembling, get final product by attachment bolt is fastening.During this period, the effect of pin is to bear tangential force.
Subsequently, the anchor clamps that assembled are installed on the workbench of lathe fixing and centering with anchor clamps.Pressing plate 8 is installed on latch segment 6, then part to be processed 14 is installed on the jig plate.Locating hole 13 on the part to be processed 14 will be aimed at the alignment pin 10 on the locating piece 5 during this period.At last, be installed in pressing plate 8 and pressing plate 8 screws on the latch segment 6 and part to be processed 14 clamped and get final product, finally as shown in figure 11.
When needs are changed different part to be processed 14, only need determining new installation site and alignment pin 10 sizes on the locating piece 5 on the softwares such as CAD again that other step is all with above-mentioned identical.
By above-mentioned character express also in conjunction with the accompanying drawings as can be seen, after adopting the utility model, by standardization, modular mentality of designing, locate mode and pressing plate 8 in conjunction with plane and two pits compress mode, when changing converted products class shape, only need change the position of alignment pin 10 and pressing plate 8 and not need to change other anchor clamps parts, can make furniture adapt to different product processing fast, not only reduce the anchor clamps manufacturing cost significantly, shorten production time, and saved resource.What is more important, this universal fixturing are very suitable for the thread-changing occasion of sample making and multi-varieties and small-batch product.
