Abstract
The utility model relates to mechanical manufacture industries, in particular to a rapid fixture for a workpiece. During machining, the rapid fixture for the workpiece can automatically clamp and release parts. A jaw is connected with a fixture base frame through screws, an eccentric cylinder is mounted on a corresponding surface of the jaw, eccentric shafts are arranged on two sides of the eccentric cylinder and inserted into a shaft seat, the shaft seat is fixedly connected with the fixture base frame, a square column is arranged at the end of one eccentric shaft and fixedly connected with a spiral arm, the tail end of the spiral arm is connected with an end joint of a cylinder through a pin, the tail end of the cylinder is connected with a shaft hole through a pin, and the shaft hole is formed in a cylinder seat of the fixture base frame. A screw hole is formed in a jaw side plate and connected with a bolt and a nut for an elongated slot of the fixture base frame. The ratio of the eccentric distance of the eccentric shafts of the eccentric cylinder to the diameter of the eccentric cylinder ranges from 1:10 to 1:20. The rapid fixture has the remarkable advantages that the machined workpiece can be rapidly clamped and released, the rapid fixture is stable and reliable in operation, and production efficiency is improved.
Description
Technical field
The utility model relates to machine industry, especially a kind of quick-speed jigs of workpiece.
Background technology
Current, in machine industry, the use of fixture is very general, and such as drilling machine, milling machine, planer etc., add man-hour to parts, must first parts be fixed, and then starts processing.For some small-sized or medium-sized parts, generally with flat-nose pliers, clamp rear processing, for flat-nose pliers, screw mandrel, silk braid act on two jaws and relatively move.During process component, clamp or unclamp parts by manually pulling its spiral arm, this is for the fine finishining parts of growing process time, and this procedure does not affect production effect, and operator's muscle power also can be born.But in process of production, in batches, fast some parts are simply added and use flat-nose pliers man-hour, as the overlap on the circular hole chamfering on workpiece, removal workpiece, operator order of classes or grades at school hundreds and thousands of repeat to clamp, loosen this class action, use again traditional flat-nose pliers, in operator's muscle power, be difficult to bear, therefore affected production efficiency.
Utility model content
The purpose of this utility model is to overcome above-mentioned technological deficiency, and a kind of quick-speed jigs of workpiece is provided, and when machining, it can automatically clamp, loosen parts.
In order to realize the purpose of this utility model, the technical scheme adopting is: by the fixture pedestal that is spirally connected for jaw, at the corresponding surface setting-up eccentricity cylinder of jaw, there is eccentric shaft eccentric cylinder both sides, and eccentric shaft inserts axle bed, the affixed fixture pedestal of axle bed, the end of one eccentric shaft is square column, the affixed spiral arm of square column, the afterbody of spiral arm connects the end-fitting of cylinder with bearing pin, and the afterbody of cylinder connects the axis hole of the cylinder block that is located at fixture pedestal with bearing pin.
On described jaw side plate, have screw, screw is connected with bolt, the nut for elongated slot of fixture pedestal.
The eccentric distance of the eccentric shaft of described eccentric cylinder and eccentric cylinder diameter ratio are in the scope of 1: 10 to 1: 20.
Distinguishing feature of the present utility model and beneficial effect are can clamp rapidly and unclamp processed workpiece, and stable and reliable during work, production efficiency is improved.
Accompanying drawing explanation
Front view when Fig. 1 is the utility model clamping work pieces.
Fig. 2 is the front view of the utility model while unclamping workpiece.
In figure: 1 workpiece, 2 jaws, 3 bolts, 4 jaw side plates, 5 elongated slots, 6 cylinder seats, 7 eccentric cylinders, 8 axle beds, 9 eccentric shafts, 10 square columns, 11 spiral arms, 12 end-fittings, 13 cylinders, 14 fixture pedestals.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, structure of the present utility model is further illustrated.
Please refer to Fig. 1 and Fig. 2, a kind of quick-speed jigs of workpiece arranges two symmetrical elongated slots 5 on fixture pedestal 14, on the jaw side plate 4 of jaw 2 both sides, respectively have in two screws, jaw screw and fixture pedestal for 14 elongated slots bolt 3, nut be connected.At the corresponding surface setting-up eccentricity cylinder 7 of jaw 2, the non-working surface of eccentric cylinder 7 cuts, and this can save material cost; There is eccentric shaft 9 eccentric cylinder 7 both sides, eccentric shaft 9 inserts the hole of axle bed 8, ball bearing (not shown) is installed between the hole of eccentric shaft 9 and axle bed 8, can be increased the precision between wearability between axle, hole and retainer shaft, hole, axle bed 8 is fixed on fixture pedestal 14; Wherein the end of an eccentric shaft 9 is square column 10, the square hole of the affixed spiral arm 11 of square column 10, and square column 11 is tight fit with square hole; Spiral arm 11 afterbodys connect the end-fitting 12 of cylinder with bearing pin, the afterbody of cylinder 13 connects the axis hole that is arranged on the cylinder block 6 on fixture pedestal 14 with bearing pin.During work, clamping work pieces 1 when the end-fitting of cylinder 13 12 shaft extension below goes out, unclamps workpiece 1 during the axle indentation below of the end-fitting 12 of cylinder 13.Between jaw 2 and eccentric cylinder 7, the ratio of the eccentric distance of the eccentric shaft 9 of change in size and eccentric cylinder 7 and eccentric cylinder 7 diameters is relevant, and also relevant with the anglec of rotation of spiral arm 11, change in size is too little, and workpiece is just difficult for taking out and putting into; Change in size is too large, and workpiece is likely not clamping; The anglec of rotation of spiral arm 11 generally can determine according to the length of the stroke of cylinder and the arm of force (eccentric shaft 9 centers are to spiral arm 11 afterbody pin shaft hole centers), the anglec of rotation of spiral arm 11 is more suitable within the scope of 20 ° to 45 °, release thus, the eccentric distance of the axle of eccentric cylinder 7 and eccentric cylinder 7 diameter ratios are more suitable in the scope of 1: 10 to 1: 20.The workpiece 1 of institute's batch machining is also different with workpiece 1 size of another batch machining, and between jaw 2 and eccentric cylinder 7, size regulates, the relative position of removable jaw side plate 4 screws in elongated slot 5.
The above, be only preferred embodiment of the present utility model, not structure of the present utility model done to any pro forma restriction.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of the technical solution of the utility model.
