Abstract
The utility model relates to a sector clamping claw device for processing a thin-walled workpiece. The sector clamping claw device for processing the thin-walled workpiece comprises a chuck, three clamping claws used for clamping a workpiece are arranged on the installation end face of the chuck with equidistance around the center of the chuck. The sector clamping claw device for processing the thin-walled workpiece is characterized in that connection plates are fixed on one sides, close to the workpiece, of the clamping claws, and the connection plates of the three clamping claws are all parts of an identical circular ring with the chuck as a center. Each connection plate is formed by an external arc surface, an internal arc surface and two end surfaces, the internal arc surfaces of the connection plates are matched with the outer surface of the workpiece, and the external arc surfaces of the connection plates are connected with the clamping claws. The sector clamping claw device for processing the thin-walled workpiece can effectively and reliably fix the workpiece, and greatly improve working efficiency, is wide in suitable range, and has no sliding friction, and is long in service life, simple in structure, and low in manufacture cost.
Description
Technical field
The utility model relates to a kind of claw, and especially a kind of fan-deck card jaw arrangement for processing thin-walled belongs to machining manufacturing equipment technical field.
Background technology
When the processing wall thickness is less than the ring-shaped work pieces endoporus of 10mm on numerically controlled lathe, because workpiece wall is thin, hold pressure that can't stand hydraulic claw, and clamping range is little, the phenomenon of clamping deformation often appears in stressed concentrating.
In prior art, a kind of mode is to adopt the socket wrench specially adapted for it frock, and the workpiece external diameter is located, and end face compression mode is processed, and this processing mode need to tighten up workpiece external diameter tolerance, has increased manufacture difficulty and cost.Another kind of mode is to stay the mill amount after Vehicle Processing, finish grindes on internal grinder, to recover the circularity of endoporus; This mode has increased by a procedure, has increased processing cost, and the hidden danger of clamping deformation is also arranged on internal grinder, needs the operative employee that higher operating experience is arranged, and human factor is very large.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of fan-deck card jaw arrangement for processing thin-walled is provided, during processing thin-walled (wall thickness is less than 10mm) endoporus, can prevent clamping deformation on numerically controlled lathe, can be effectively and clamping thin-wall part reliably.
According to the technical scheme that the utility model provides, described fan-deck card jaw arrangement for processing thin-walled comprises chuck, equidistant round the center of chuck on the installation end face of chuck three claws that are used for holding workpiece is set; It is characterized in that: near a side fixed connecting plate of workpiece, the connecting plate on three claws is the part of the same annulus centered by chuck at described claw; Described connecting plate is comprised of outer arc face, inner arc face and both ends of the surface, and the inner arc face of connecting plate matches with the outer surface of workpiece, and the outer arc face of connecting plate is connected with claw.
The angle of described connecting plate both ends of the surface is 90 °.
On the outer arc face of described connecting plate, boss is set, at the cell body that claw coordinates with boss near a side setting of workpiece, claw passes through the second trip bolt and is connected with boss on connecting plate.
Described claw is fixed on chuck by the first trip bolt.
The utlity model has following advantage: (1) the utility model can be effectively, fixation workpiece reliably, greatly improves the stability of crudy; (2) the utility model can effectively be eliminated the possibility of clamping deformation; (3) the utility model clamping is convenient, and basic clamped one time is completed, and greatly increases work efficiency; (4) the utility model scope of application is wider, and fricton-tight friction, and the life-span is longer; (5) the utility model is simple in structure, and manufacturing cost is lower.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cutaway view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As Fig. 1 ~ shown in Figure 2: as described in comprise chuck 1, claw 2, connecting plate 3, the first trip bolt 4, the second trip bolt 5, workpiece 6, boss 7 etc. for the fan-deck card jaw arrangement of processing thin-walled.
As shown in Figure 1, the utility model comprises chuck 1, equidistant round the center of chuck 1 on the installation end face of chuck 1 three claws 2 that are used for holding workpiece 6 is set, and claw 2 is fixed on chuck 1 by the first trip bolt 4 respectively; Be the part of the same annulus centered by chuck 1 near the connecting plate 3 on 3, three claws 2 of a side fixed connecting plate of workpiece 6 at described claw 2; Described connecting plate 3 is comprised of outer arc face, inner arc face and both ends of the surface, and the inner arc face of connecting plate 3 matches with the outer surface of workpiece 6, and the outer arc face of connecting plate 3 is connected with claw 2, and the angle of both ends of the surface is 90 °;
As shown in Figure 2, on the outer arc face of described connecting plate 3, boss 7 is set, at the cell body that described claw 2 coordinates with boss 7 near a side setting of workpiece 6, claw 2 passes through the second trip bolt 5 and is connected with boss 7 on connecting plate 3.
Operation principle of the present utility model: the utility model is annulus at first, and it is the connecting plate 3 of 90 ° that annulus is divided into three central angles; Because there is certain angle between the both ends of the surface of connecting plate 3, thereby increase the holding area of workpiece 6 outer surfaces, clamping force is evenly distributed on workpiece 7 cylindricals, avoided stressed and concentrated, effectively eliminated the clamping deformation phenomenon of workpiece.The connecting plate that the utility model adopts can increase the holding area of excircle of workpiece, and clamping force is evenly distributed, thus clamping work pieces and workpiece can be out of shape effectively reliably.
