Description
Technical field
The utility model relates to workpiece machining frock, is specifically related to a kind of unsteady rigid support device for the blank surface of workpiece auxiliary positioning.
Background technology
When holing at the boss of a kind of steel-casting shift fork of processing with at the boss place, for guaranteeing product size, design basis is overlapped with positioning datum, therefore, must select the inner chamber location that front operation processed, and the shift fork outer surface is unprocessed black skin, can't locates with outer surface.Because the boss face that need process and the position of drill hole are longer with the distance that compresses the some position, and this part can only unsettled clamping, the hanging part poor rigidity, so, the perpendicularity poor stability of size and drilling axis when processing boss and boring, qualification rate is about 50%.
Summary of the invention
The purpose of this utility model provides a kind of unsteady rigid support device for the blank surface of workpiece auxiliary positioning, it can be on the black skin of workpiece hanging part, realize fast stable, reliable rigidity supplemental support, solution adds man-hour at the workpiece hanging part, because poor rigidity causes the problem of unstable product quality, improve the qualification rate of product.
A kind of unsteady rigid support device for the blank surface of workpiece auxiliary positioning described in the utility model comprises base plate, is connected to holder on the base plate by sunk screw, and the centre of described holder is provided with up-small and down-big ladder hole, it is characterized in that:
The middle part of one support column is provided with an annular boss, and the face of cylinder, top of described support column is provided with a keyway, and the centre on described support column top is provided with hemisphere projection; The upper end that the top of the ladder hole in the top cylinder of described support column and described holder centre is slidingly matched and stretches out described holder;
One Compress Spring is enclosed within on the lower cylindrical of described support column, and is positioned at the bottom of the ladder hole in described holder centre; The annular boss at the upper end of described Compress Spring and described support column middle part near, the lower end of described Compress Spring and described base plate top near;
One lock-screw is connected with the screw that is located at described holder top, the termination of described lock-screw be located at described support column top cylinder on the corresponding contact of keyway.
Described a kind of unsteady rigid support device for the blank surface of workpiece auxiliary positioning is provided with a dust excluding plate in the extending area near described support column upper end.
Further, described dust excluding plate adopts oil resistant rubber to make, and its middle part is provided with a hole and is tightly placed in by this hole on the cylinder of support column extension.
Lay unsteady supplemental support at unsettled working position, and realize fast unsteady process to rigid conversion, and do not produce the location with positioning datum, do not produce vibration and strain man-hour to strengthen the rigidity of product, to make to add, guarantee product processing quality.Lay this bracing or strutting arrangement at the workpiece hanging part, during clamping workpiece, support column floats under the elastic force effect of Compress Spring, contact with blank surface of workpiece all the time, but elastic force can not be large, move as long as under free state, can promote support column, and after clamping workpiece is good, support column pressurized and elastic force that Compress Spring is produced can not make workpiece produce strain, at this moment, the support column that floats by lock-screw locking again can not move it and becomes rigid support.
Useful technique effect of the present utility model: by using this bracing or strutting arrangement, when holing at the boss of processing steel-casting shift fork with at the boss place, because the rigidity of workpiece has obtained enhancing, or else can produce strain and vibration, make the product percent of pass of processing bring up to 100% by 50%.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of support column of the present utility model;
Fig. 3 is the A-A sectional drawing of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of unsteady rigid support device for the blank surface of workpiece auxiliary positioning, comprise base plate 7, be connected to holder 3 on the base plate by sunk screw 5, the centre of described holder is provided with up-small and down-big ladder hole, and its innovative point is:
The middle part of one support column 1 is provided with an annular boss 1-3, and the face of cylinder, top of described support column is provided with a keyway 1-2, and the centre on described support column top is provided with hemisphere projection 1-1; The upper end that the top of the ladder hole in the top cylinder of described support column 1 and described holder 3 centres is slidingly matched and stretches out described holder 3;
One Compress Spring 6 is enclosed within on the lower cylindrical of described support column 1, and is positioned at the bottom of the ladder hole in described holder 3 centres; The annular boss 1-3 at the upper end of described Compress Spring 6 and described support column 1 middle part near, the lower end of described Compress Spring 6 and described base plate 7 top near;
One lock-screw 4 is connected the termination of described lock-screw 4 and the corresponding contact of keyway 1-2 that is located at described support column 1 top cylinder with the screw that is located at described holder 3 tops.
