Abstract

The invention discloses a clamp for clamping a box body type workpiece. The clamp comprises a square base plate, wherein supporting columns are respectively arranged on four corners of the base plate, press plates are arranged at the top ends of the supporting columns, multiple positioning pins and adjusting bolts are arranged on the base plate, and two elastic positioning pins are arranged at the middle position of the base plate. The clamp can be quickly spliced and adjusted and has the advantages of being high in positioning accuracy, firm and reliable in clamping and suitable for small-batch multi-variety production.

Description

The clamping device of box-type workpieces
Technical field
The present invention relates to fixture, especially, relate to a kind of clamping device of box-type workpieces.
Background technology
Box-type workpieces has following feature: one is that processing content is many, needs frequently to change lathe, cutter; Two is that requirement on machining accuracy is high, adopts machine tool crudy to be difficult to ensure, and due to technological process long, number of turnover institute, production efficiency is difficult to raising; Three is complex-shaped, and major part is thin-wall case, and workpiece stiffness is poor, more difficult clamping.Adopt numerical control machining center to carry out casing processing, by means of machining center self precision and working (machining) efficiency is high, the feature of good rigidity and automatic tool changer.As long as make technological process, design adopts rational special fixture and cutter, just can solve the problem completely.So for the feature of box-type workpieces, the special fixture how designing a kind of applicable box-type workpieces is exactly industry problem demanding prompt solution.
Summary of the invention
The object of the invention is the clamping device providing a kind of box-type workpieces, and to solve in prior art, box-type workpieces workpiece stiffness is poor, the problem of more difficult clamping.
For achieving the above object, the invention provides a kind of clamping device of box-type workpieces, comprise: the base plate be square, the corner of described base plate is respectively arranged with support column, the top of described support column is provided with pressing plate, described base plate is provided with multiple alignment pin and adjustment bolt, is provided with two elastic positioning pins in the middle part of described base plate.
Further, described elastic positioning pin comprises the location division in truncated cone shape, is provided with elastic component below described location division.
Further, described alignment pin is provided with four, and described adjustment bolt is provided with four.
The present invention has following beneficial effect:
This fixture can quick-assembling and adjustment, has positioning precision high, clamps solid and reliable, is applicable to the productive prospecting of small lot multi items.
Accompanying drawing explanation
Below with reference to figure, the present invention is further detailed explanation.The accompanying drawing forming a application's part is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of the clamping device preferred embodiment of box-type workpieces of the present invention.
Description of reference numerals:
1, base plate; 2, support column; 3, pressing plate; 4, alignment pin; 5, bolt is adjusted; 6, elastic positioning pin.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.
Refer to Fig. 1, the preferred embodiments of the present invention provide a kind of clamping device of box-type workpieces, comprise: the base plate 1 be square, the corner of described base plate 1 is respectively arranged with support column 2, the top of described support column 2 is provided with pressing plate 3, described base plate 1 is provided with multiple alignment pin 4 and adjustment bolt 5, the middle part of described base plate 1 is provided with two elastic positioning pins 6.During use, workpiece is set level and form plane on adjustable for height alignment pin 4, and two elastic positioning pins 6 on base plate 1 coordinate with the pilot hole on workpiece.Meanwhile, whether verification workpiece left and right center line, in same level, if the position not utilizing adjustment bolt 5 to finely tune workpiece, till correction, finally uses pressing plate 3 by Work-sheet pressing.This fixture can quick-assembling and adjustment, has positioning precision high, clamps solid and reliable, is applicable to the productive prospecting of small lot multi items.
Preferably, described elastic positioning pin 6 comprises the location division in truncated cone shape, the shape of the frustum of a cone can better and the pilot hole of workpiece coordinate, be provided with elastic component below described location division.
Preferably, described alignment pin 4 is provided with four, and described adjustment bolt 5 is provided with four.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention; For a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
