Description

Fixtures for processing radiator tube sheets

technical field

The utility model relates to the field of radiator tube plate processing, in particular to a fixture for radiator tube plate processing.

Background technique

The size of the tube sheet of the radiator varies with the product, and the length, width, and thickness vary with the product, and the length dimension may even exceed the stroke of the machine tool; during the processing of the tube sheet, the amount of chips is large, so the fixture is required to provide a firm clamping force . If special fixtures are made for each type of tubesheet, the processing cost will be greatly increased; but with simple fixtures, the clamping force is not enough to fix the tubesheet, it is not easy to reposition, easy to produce positioning errors, and affect the processing quality of the tubesheet. And the positioning of the cards is more complicated.

Utility model content

Aiming at the defects of the prior art, the purpose of this utility model is to design a universal fixture for processing radiator tube sheets on a machine tool, which can realize clamping of most radiator tube sheets.

The technical solution adopted by the utility model is that the main body of the fixture is fixedly connected with a pad and two height adjustment columns; the upper end of each height adjustment column is fitted with one end of the pressure plate and then fixed by a height adjustment bolt, and the other end of the pad and the pressure plate is clamped tightly. The fixed bolts are fixed with gaps, and the main body of the fixture is provided with a long hole connected with the machine table.

Two height adjustment columns are separately arranged at both ends along the length direction of the pad.

A groove is arranged on one side of the upper end of the pad, and the groove is formed vertically by a clamping surface and a fixing surface.

The long holes are spaced and arranged in parallel along the length direction of the fixture main body, and the long sides of the long holes are perpendicular to the long sides of the pad.

The beneficial effect of the utility model is that after the design and application of the clamp, clamping and clamping can be realized according to the specific shape of the radiator tube plate to be processed, and it has strong versatility, accurate positioning, firm clamping, high processing precision, It has the characteristics of easy operation, saves the time and cost of manufacturing special fixtures, reduces production costs, and improves production efficiency.

Detailed ways

Now in conjunction with accompanying drawings 1 and 2, the utility model is further described: the universal fixture for radiator tube plate processing described in the utility model includes a fixture main body 1, a pad 2, a height adjustment column 3, a pressure plate 4, and a height adjustment bolt 5. Fastening bolts 6 and long holes 7 for clamping; 1 on the main body of the fixture is fixedly connected with pad 2 and 2 height adjustment columns 3; the upper end of each height adjustment column 3 is fitted with a pressure plate 4 and then fixed by the height adjustment bolt 5, the pressure plate 4 The other end is provided with clamping fastening bolts 6, there is a gap between the pressure plate 4 and the pad 2, and the fixture main body 1 is provided with a long hole 7 connected with the machine table, and the two height adjustment columns 3 are separated It is arranged at both ends along the length direction of the pad 2 . Both sides of the upper end of the pad 2 are grooves 9 along the length direction. The groove 9 is formed vertically by a clamping surface 10 and a fixing surface 11. The clamping surface 10 and the pressing plate respectively clamp the upper and lower sides of the radiator tube plate 8 to be processed, and the fixing surface 11 is used to fix the width of the radiator tube plate 8 to be processed. Positioning in the direction, the long holes 7 are spaced and arranged in parallel along the length direction of the clamp body 1 , and the long sides of the long holes 7 are perpendicular to the long sides of the pad 2 .

The long hole 7 on the fixture main body 1 can be connected with the machine tool workbench, and can be adjusted according to the width of the radiator tube plate, that is, the fixture for processing the radiator tube plate can be adjusted in width, and it is compatible with the radiator tube plate 8 to be processed. Adapt. There is no restriction on the length direction of radiator tube sheets, and longer radiator tube sheets can be processed. Fastening bolt 6 and pressure plate 4 are used to fix the radiator tube plate 8 to be processed to provide a firm clamping force; the height adjustment bolt 5 at the tail of the pressure plate 4 can be adjusted along the height according to the thickness of the radiator tube plate 8 to be processed The column 3 is adjusted to maximize the contact area between the pressure plate 4 and the radiator tube plate 8 to be processed, to enhance the clamping force, and to eliminate the indentation of the pressure plate 4 to the radiator tube plate 8 to be processed. They can be used in pairs according to the length or processing range of the radiator tube plate 8 to be processed.
