The invention discloses a groove milling clamp and belongs to the field of farm machinery. The groove milling clamp is characterized in that the clamp comprises a clamp body (1), a floating lever (2), a positioning key (3), a screw (4), a hinge screw (5), pins (6), movable wide-head pressing plates (7), swing bolts (8), positioning pins (9), nuts (10), cylindrical compression springs (11), set screws (12) and thin nuts (13); the floating lever (2) is connected with the swing bolts (8) through the pins (6); the cylindrical compression springs (11) are installed on the swing bolts (8) and placed between the clamp body (1) and the movable wide-head pressing plates (7); the movable wide-head pressing plates (7) are connected with the clamp body (1) through the set screws (12); the matched thin nuts (13) are installed at the ends, close to the clamp body (1), of the set screws (12). The problem that existing groove milling clamps are low in production efficiency and precision is solved.

Description

A kind of slotting attachment
Technical field
The invention belongs to field of agricultural machinery, particularly relate to a kind of slotting attachment.
Background technology
Process increasingly competitive today in machine-building, high efficiency, low cost, for manufacturer, seem particularly important; Traditional fixture can not meet high speed, high efficiency production requirement, and therefore, some fixtures efficiently linked are promoted gradually and use; The part such as connecting rod, plug screw is the common part of the farm machinery such as tractor, united reaper; And the tradition processing of milling crank-guide way, plug screw flat recess is with flat-nose pliers single-piece clamping groove milling on milling machine, production efficiency is low, and precision is not high; Flat-nose pliers is the main accessories of milling, pincers, numerical control, machining center clamping workpiece, its simple structure, clamping firmly, easy to use, process the plane of general part, step, inclined-plane, groove, boring etc., can process with flat-nose pliers clamping, if but the multiple workpiece having position dimension requirement of time processing, flat-nose pliers then seems " unable to do what one wishes ".
Summary of the invention
The object of this invention is to provide a kind of slotting attachment, solve existing slotting attachment production efficiency low, the problem that precision is not high.
In order to achieve the above object, the present invention by the following technical solutions, a kind of slotting attachment, comprise clamp body, floating lever rod, positioning key, screw, hinge screws, pin, mobile wide head pressing plate, eyelet bolt, alignment pin, nut, cylindrical compression spring, holding screw and thin nut, wherein floating lever rod is connected with eyelet bolt by pin, eyelet bolt is equipped with cylindrical compression spring, cylindrical compression spring is placed between clamp body and mobile wide head pressing plate, mobile wide head pressing plate is connected by holding screw with clamp body, near holding screw one end of clamp body, supporting thin nut is housed, the other end of 2 eyelet bolts that floating lever rod connects one of them connect be supporting nut, what another connected is supporting thin nut, and be all placed in above mobile wide head pressing plate.
A kind of slotting attachment, wherein the eyelet bolt other end connects the number of supporting thin nut is 2, and often the mobile wide head pressing plate of group has 2, has 4 groups.
The invention has the beneficial effects as follows: this slotting attachment can process 8 workpiece simultaneously, linking clamping mechanism achieves and simplifies the operation, as long as tighten a nut, the pressing plate at two ends is just simultaneously by two workpiece multiple spot clamping, as long as the positioning key in fixture is changed into a straight pin and a rhombus pin is located in connecting rod holes, just can milling crank-guide way equally; The clamping time can be saved, alleviate the labour intensity of workman, boost productivity.
Accompanying drawing explanation
Fig. 1 is slotting attachment structural representation.
Fig. 2 is slotting attachment plan structure schematic diagram.
In figure, 1, clamp body, 2, floating lever rod, 3, positioning key, 4, screw, 5, hinge screws, 6, pin, 7, mobile wide head pressing plate, 8, eyelet bolt, 9, alignment pin, 10, nut, 11, cylindrical compression spring, 12, holding screw, 13, thin nut.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described, as shown in Figures 1 and 2, a kind of slotting attachment, comprise clamp body 1, floating lever rod 2, positioning key 3, screw 4, hinge screws 5, pin 6, mobile wide head pressing plate 7, eyelet bolt 8, alignment pin 9, nut 10, cylindrical compression spring 11, holding screw 12 and thin nut 13, wherein floating lever rod 2 is connected with eyelet bolt 8 by pin 6, cylindrical compression spring 11 eyelet bolt 8 is equipped with, cylindrical compression spring 11 is placed between clamp body 1 and mobile wide head pressing plate 7, mobile wide head pressing plate 7 is connected by holding screw 12 with clamp body 1, near holding screw 12 one end of clamp body 1, supporting thin nut 13 is housed, on floating lever rod 2 connect 2 eyelet bolts 8 the other end one of them connect be supporting nut 10, what another connected is supporting thin nut 13, and be all placed in above mobile wide head pressing plate 7.
A kind of slotting attachment, as shown in Figures 1 and 2, wherein eyelet bolt 8 other end connects the number of supporting thin nut 13 is 2, and often the mobile wide head pressing plate 7 of group has 2, has 4 groups.
A kind of slotting attachment, as shown in Figures 1 and 2, workpiece is located on alignment pin 9 with hole, and fastening nut 10 drives floating lever rod 2 by eyelet bolt 8, makes two secondary mobile wide head pressing plates 7 clamp two workpiece equably simultaneously; This slotting attachment can process 8 workpiece simultaneously, is matched by two positioning keys 3 on clamp body 1 bottom surface, determine the tram of fixture on lathe with the T-slot on milling machine table; Distance between two positioning keys 3 is larger, and orientation accuracy is higher; Except location, positioning key 3 receiving portion can also divide cutting torque, alleviates the load of fixture set bolt, increases the stability of fixture; Two ear seats on clamp body 1 facilitate fixture fixing on milling machine table; If the required precision of part is higher, feeler block can be set in clamp body one end, determines the relative position of cutter and fixture; As long as the positioning key 3 in fixture is changed into a straight pin and a rhombus pin is located in connecting rod holes, just can milling crank-guide way equally.
The present invention does not describe part in detail, is the known technology of those skilled in the art of the present technique.
