Clamp base
Technical field
The utility model relates to the Equipment Technology field, especially relates to a kind of clamp base.
Background technology
In the existing fixture for grinding machine structure, the upper and lower support plate of anchor clamps is connected with pin by screw, adopts this split type fixture for grinding machine in rotary course, and anchor clamps distortion itself is very big, rigidity is bad, causes the part endoporus ovality that processes to produce in various degree overproof.The common method that solves the fixture for grinding machine stiff problem at present is the thickness that increases clamp base, but increase the thickness of clamp base simply, can make the weight of clamp base might surpass the maximum capacity amount of machine tool chief axis, general-purpose grinder main shaft maximum capacity is 500 kilograms, make grinding machine spindle easily produce distortion, damage equipment.
The utility model content
The purpose of this utility model provides a kind of clamp base, can when guaranteeing the anchor clamps rigidity, can farthest alleviate the weight of clamp base again, make anchor clamps in grinding process, have enough rigidity, do not deform, to guarantee the Geometrical Tolerance Principle of product.
For achieving the above object, the utility model provides a kind of clamp base, comprise upper supporting plate, lower carrier plate, side plate and ring stiffener, described upper supporting plate, described lower carrier plate, described side plate and described ring stiffener are cast into integrative-structure, and described upper supporting plate is connected by described ring stiffener with described lower carrier plate.
Therefore, the utility model adopts the clamp base of said structure, can be when guaranteeing the anchor clamps rigidity, can farthest alleviate the weight of clamp base again, make anchor clamps in grinding process, have enough rigidity, do not deform, to guarantee the Geometrical Tolerance Principle of product.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment
Embodiment
Fig. 1 is the structural representation of the utility model fixture for grinding machine base embodiment, as shown in Figure 1, comprise upper supporting plate 1, lower carrier plate 2, side plate 3 and ring stiffener 4, upper supporting plate 1, lower carrier plate 2, side plate 3 and ring stiffener 4 are cast into integrative-structure, upper supporting plate 1 is connected by ring stiffener 4 with lower carrier plate 2, Fig. 2 be the utility model clamp base embodiment in Fig. 1 A-A to view.2 be provided with through hole 5 on upper supporting plate 1 and the lower carrier plate in the present embodiment, be provided with in the through hole and add mandrel 6, it is fixing with nut 7 at upper supporting plate 1 upper surface to add mandrel 6, part to be processed is installed in clamp base and adds on the mandrel 6, nut 7 is used for tightening up adding mandrel 6, upper supporting plate 1, lower carrier plate 2 and part, has so also increased the structural rigidity of clamp base.The increase of ring stiffener 4, make upper supporting plate 1 more reliable with being connected of lower carrier plate 2, make clamp base and part on grinding machine during rotary grinding, limit the distortion of upper and lower support plate from all angles, effectively prevented the distortion that in rotary course upper and lower support plate produces because of the influence of centrifugal force, the deflection of base is significantly reduced, thereby reduced the ovality of part endoporus, solve the overproof problem of part endoporus ovality.
Upper supporting plate 1 and lower carrier plate 2 roots can adopt circular arc 8 transition in the present embodiment, reduce the internal stress of upper supporting plate 1 and lower carrier plate 2 roots, prevent the clamp base distortion.
Therefore, the utility model adopts the clamp base of said structure, can be when guaranteeing the anchor clamps rigidity, can farthest alleviate the weight of clamp base again, make anchor clamps in grinding process, have enough rigidity, do not deform, to guarantee the Geometrical Tolerance Principle of product.
It should be noted that at last: above embodiment is only in order to explanation the technical solution of the utility model but not limit it, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that: it still can make amendment or be equal to replacement the technical solution of the utility model, and these modifications or be equal to replacement and also can not make amended technical scheme break away from the spirit and scope of technical solutions of the utility model.
