Abstract
The utility model discloses a long-shaft workpiece supporting center frame which comprises a frame body. Three movable claws which are evenly and circumferentially distributed are arranged on the frame body. Rolling bearings are respectively arranged at positions at which the three claws are in contact with a workpiece. Since the rolling bearings are respectively arranged at the positions at which the three claws of the center frame are in contact with the workpiece, the rolling bearings are in contact with the workpiece in a workpiece supporting process and rolling contact is formed between the workpiece and the claws, the positioning accuracy of the workpiece is improved, the adjustment during clamping is facilitated and the rolling contact can reduce the surface wear of the workpiece.
Description
Technical field
The utility model relates to a kind of long-axle workpieces centre of support frame.
Background technology
When the working shaft-like part, normally an end clamps, the other end holds out against with top, but run into workpiece when longer, the workpiece middle part can produce sagging around song, thereby influence crudy, so generally all support workpiece with centre frame at the middle part of this long-axle workpiece, but the claw of centre frame commonly used is a kind of slidingtype with contacting of workpiece, has slip relatively between the two, when the pinching end of workpiece circumference occurs and beats, centre frame is difficult to workpiece support to the processing pivot, cause the clamping difficulty, reduce the positioning accuracy of workpiece, and the claw of this centre frame in use also can bring bigger wearing and tearing to workpiece.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of long-axle workpieces centre of support frame is provided, not high, the wear and tear problem of workpiece easily of positioning accuracy when solving existing centre frame supporting workpiece.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of long-axle workpieces centre of support frame, comprise support body, support body is provided with at three uniform claws that can move respectively of circumferencial direction, and described three claws and workpiece contact jaw portion are provided with rolling bearing respectively.
The beneficial effects of the utility model are: the utility model is provided with rolling bearing at the claw of centre frame and the contact position of workpiece, rolling bearing contacts with workpiece in the supporting workpiece process, make and form roller between workpiece and the claw and contact, thereby improved the positioning accuracy of workpiece, adjustment when also helping clamping is more convenient, and roller contact has simultaneously also reduced the wearing and tearing to surface of the work.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. support bodys, 2. claws, 3. rolling bearings among the figure
The specific embodiment.
In conjunction with the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of long-axle workpieces centre of support frame as shown in Figure 1, comprise support body 1, support body 1 is provided with three movably claws 12, three claws 2 are uniform in a circumferential direction, can move adjusting respectively, be provided with rolling bearing 3 at described three claws 2 respectively with workpiece contact jaw portion, when clamping is adjusted, three claws 2 can be guaranteed workpiece centre and the uniformity of processing pivot, behind the supporting workpiece according to the morpheme error do adjusting separately of workpiece itself, rolling bearing 3 contacts with workpiece, the formation roller contacts, thereby has improved the positioning accuracy of workpiece, has also reduced the wearing and tearing to surface of the work.
Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection domain of the present utility model.
Claims (1)
