Radiator tube sheet fixture for processing
The utility model relates to radiator tube sheet manufacture field, is specifically related to a kind of radiator tube sheet fixture for processing.
The tubesheet dimension of radiator is different because of product, and length, width, thickness are all with product variations, and length dimension even can exceed the stroke of lathe; In the process of tube sheet, scrap rate is large, therefore requires that fixture provides firmly clamping force.If make special fixture for often kind of tube sheet, so greatly processing cost can be improved; And just use easy fixture, insufficient clamping force, with fixed tube sheet, is not easy to relocate, and easily produces position error, affects the crudy of tube sheet, and the location that is installed is more loaded down with trivial details.
Utility model content
For the defect of prior art, the utility model object designs a kind of universal fixturing of processing heat radiator tube sheet on lathe, can realize being installed of most radiator tube sheet.
The technical solution adopted in the utility model is, jig main body is fixed with pad, 2 height adjustable columns; Every root height adjustable column upper end is fixed by height adjustment bolt behind suit pressing plate one end, and pad and the pressing plate other end have gap to fix by the fastening bolt that is installed, and jig main body is provided with the elongated hole be connected with platen.
2 height adjustable columns are disposed on two ends along pad length direction.
The side, upper end of pad is provided with groove, and groove is formed by clamping face is vertical with stationary plane.
Elongated hole is along layout spaced-apart parallel on jig main body length direction, and the long limit of elongated hole is perpendicular to the long limit of pad.
The beneficial effects of the utility model are, after the design and application of this fixture, can realize clamping clamping according to the concrete shape of radiator tube sheet to be processed, features such as there is highly versatile, accurate positioning, be installed firmly, machining accuracy is high, easy and simple to handle, and save the time and cost that manufacture special fixture, reduce production cost, enhance productivity.

Detailed description of the invention
Now by reference to the accompanying drawings 1,2, the utility model is further described: the universal fixturing of radiator tube sheet processing described in the utility model, comprises jig main body 1, pad 2, height adjustable column 3, pressing plate 4, height adjustment bolt 5, the fastening bolt 6 that is installed, elongated hole 7; On jig main body, 1 is fixedly connected with pad 2,2 height adjustable column 3; Fixed by height adjustment bolt 5 after the suit pressing plate 4 of every root height adjustable column 3 upper end, pressing plate 4 other end is provided with the fastening bolt 6 that is installed, gap is had to fix between pressing plate 4 and pad 2, jig main body 1 is provided with the elongated hole 7 be connected with platen, and 2 described height adjustable columns 3 are disposed on the two ends along pad 2 length direction.The both sides, upper end of described pad 2 are groove 9 along its length.Groove 9 is formed by clamping face 10 is vertical with stationary plane 11, clamping face 10 and pressing plate clamp the top and bottom of radiator tube sheet 8 to be processed respectively, stationary plane 11 is for the width location of fixing radiator tube sheet 8 to be processed, described elongated hole 7 is along spaced-apart parallel layout on jig main body 1 length direction, and the long limit of elongated hole 7 is perpendicular to the long limit of pad 2.
Elongated hole 7 on jig main body 1 can be connected with platen, and can regulate according to the width dimensions of radiator tube sheet, namely radiator tube sheet fixture for processing can regulate on width, carries out adaptation with radiator tube sheet 8 to be processed.Radiator tube sheet length direction is not limited, the radiator tube sheet of longer size can be processed.Be installed fastening bolt 6 and pressing plate 4 is used for fixing radiator tube sheet 8 to be processed, provides firmly clamping force; The height adjustment bolt 5 of pressing plate 4 afterbody, can regulate along height adjustable column 3 according to radiator tube sheet 8 thickness to be processed, pressing plate 4 is maximized with the contact area of radiator tube sheet 8 to be processed, strengthens clamping force, the impression that processing heat radiator tube sheet 8 treated by pressure 4 plate can be eliminated.According to the length of radiator tube sheet 8 to be processed or the range of work, can use in pairs.
