Abstract
The utility model relates to a centre frame with bearings, which comprises a base, a circular support, and three supporting columns uniformly distributed on the circular support. The main technical characteristics are as follows: sliding blocks at the top ends of the supporting columns are changed into the bearings, and the centers of the top ends of the supporting columns are provided with grooves; the groove walls of the two sides of the grooves are symmetrically provided with circular through holes, and the bearings are fixed in the grooves through shafts; and the shafts exactly pass through the through holes. The sliding blocks at the top ends of the supporting columns are changed into the bearings, so that the friction between a workpiece and the top ends of the supporting columns of the center frame when processing is greatly decreased, and the degree of finish of the surface of the workpiece is ensured; and simultaneously, the bearings are not easy to wear and tear, and the phenomenon that the workpiece is unstably clamped due to wear and tear can be prevented, so that the processing size of the workpiece is more precise, the replacement expenses are saved because of long service life, and the cost is reduced.
Description
Technical field
The centre frame that the utility model provides a kind of tape spool to hold belongs to the machine tooling field.
Background technology
Usually in machined into, produce flexural deformation, usually on bed ways, select the suitable fastening centre frame in position as aiding support, to increase the workpiece rigidity in order to prevent workpiece to be subjected to the effect of radial cutting force.As shown in Figure 1, be evenly distributed with three support columns on the centre frame, the support column top is provided with cast iron slide block (as shown in Figure 1 9), regulates three cast iron slide blocks it is contacted with the work mounting s face, and be adjusted to that degree of tightness is suitable to get final product.But the centre frame that is provided with slide block some problems can occur when supporting workpiece: seamed edge is arranged on the slide block, can stay cut on processing work when holding workpiece, influence the fineness of surface of the work; Slide block weares and teares easily, makes the piece-holder shakiness, thereby influences the accuracy of workpiece processing dimension, if want to keep the stability of piece-holder then to need to change simultaneously three slide blocks, input cost is bigger.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: the centre frame that provides a kind of tape spool to hold, having solved the workpiece that produces because of the centre frame clamping has the problem of cut, and because not easy to wear saving of bearing changed required spending, has reduced cost.
The technical scheme that its technical problem that solves the utility model adopts is: the centre frame that a kind of tape spool holds comprises base, circular support and is evenly distributed on three support columns on the circular support that it is characterized in that: the support column top is equipped with bearing.
Optimized technical scheme is: support column top central authorities have concave groove, and symmetry has manhole on the cell wall of concave groove both sides, and bearing is fixed in the concave groove by axle, and axle just passes two manholes.
The beneficial effect that the utility model had is: change bearing into by the slide block with the support column top, reduced to add workpiece and the friction on centre frame support column top in man-hour greatly, guaranteed the fineness of surface of the work, simultaneously, bearing is difficult for wearing and tearing, and does not also have the phenomenon of the piece-holder shakiness that produces because of wearing and tearing, thereby makes the processing dimension of workpiece more accurate, and saved it because of its long service life and changed required spending, reduced cost.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, former centre frame comprises base 1, circular support 2 and is evenly distributed on three support columns 3 on the circular support 2 that support column 3 tops are provided with slide block 9; As shown in Figure 2, the centre frame that holds of the utility model tape spool changes the slide block 9 on support column 2 tops into bearing 7.
