Abstract
The utility model discloses a round clamp which comprises a clamp body. The round clamp is characterized in that a through hole is formed at the center of the clamp body, and grooves used for mounting of tile-shaped products are formed in the clamp body. Rotating of the products is controlled through the clamp, and a circular-arc surface is ground through a cylindrical grinding wheel 6, so that size of the circular-arc surface can be controlled effectively, accuracy of the circular-arc surface is improved, surface grinding cracks of the circular-arc surface are reduced, and using limitation of the grinding wheel is reduced; different products can be ground by a same grinding wheel, so that using cost of the grinding wheel is lowered to some extent.
Description
Technical field
The utility model relates to a kind of circular clamp, relates in particular to a kind of watt circular clamp for type product grinding extrados that is exclusively used in.
Background technology
The magnet steel using in the metal industry such as neodymium iron boron, adopts rare earth material to make conventionally; This class magnet steel exist hardness large, the shortcoming such as to rupture, thereby cause processing difficulties;
At present, the radian tolerance of watt circular arc of type product to magnet steel is generally all higher, and existing mill arc technique normally adopts the horizontal grinding magnet steel of circular arc type emery wheel arc surface; This mill arc technological requirement watt center of type product and the center of emery wheel are coplanar in vertical direction, in curved face processing process, because beating or wearing and tearing appears in emery wheel in rotation, cause the magnet steel cambered surface grinding cannot reach requirement, this just makes the qualification rate of product greatly reduce, and causes the waste of material; Meanwhile, in traditional mill arc technique, need to manually carry out the shake of handwheel, in the process of handwheel shake, easily produce the displacement of workbench; Thereby cause the polishing scratch of product surface large.
Utility model content
The utility model, in order to make up the deficiencies in the prior art, provides a kind of circular clamp simple in structure; This fixture can be controlled the size of arc surface effectively, improves the precision of arc surface, reduces the surperficial polishing scratch of arc surface.
For achieving the above object, the technical scheme that the utility model is taked is:
A kind of circular clamp, comprises chuck body; It is characterized in that: the center of described chuck body is provided with a through hole; Described chuck body is provided with for a watt groove for type product is installed;
Further improve, the diameter of described through hole is equal to or slightly greater than the diameter of grinding machine spindle;
Further improve, the quantity of described groove is N;
Compared with prior art, adopt such scheme, the beneficial effects of the utility model are: the utility model is by chucking surface, groove being set, and a watt type product is arranged in this groove, realize the grinding of arc surface by the rotation of fixture; Can effectively control the size of arc surface, improve the grinding accuracy of arc surface; Meanwhile, reduce the surperficial polishing scratch of arc surface.
brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 utilizes the utility model that product structure schematic diagram is installed;
Fig. 3 utilizes the utility model to carry out the structural representation of arc surface grinding;
detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, a kind of circular clamp, comprises chuck body 2; The center of described chuck body 2 is provided with a through hole 3; The diameter of through hole 3 is equal to or slightly greater than the diameter of grinding machine spindle; Chuck body 2 can be embedded on grinding machine spindle by this through hole 3; Described chuck body 2 is provided with for a watt groove for type product 1 is installed; The quantity of described groove 1 is N, and preferably, in the present embodiment, the quantity of groove 1 is 9; The shape of groove 1 is unfixing, can be arranged to circle, rectangle, square, triangle or ellipse according to a watt shape for type product; Preferably, in the present embodiment, groove 1 adopts oval;
Utilize above-mentioned fixture to carry out the method for arc surface grinding, comprise the following steps:
Shape and the size of the first step, basis watt type product 4 are offered groove 1 on the surface of chuck body 2;
Second step, a watt type product 4 is arranged in groove 1, as shown in Figure 2;
The 3rd step, be arranged on the cylindrical grinder main shaft 5 of grinding machine 8 watt fixture of type product 4 is housed, fixture can be being rotated freely on cylindrical grinding machine spindle 5, as shown in Figure 3;
The 4th step, cylindrical grinding wheel 6 is arranged on the rotary main shaft 7 of grinding machine 8, cylindrical grinding wheel 6 can be moved in the horizontal direction, as shown in Figure 3;
The 5th step, startup grinding machine 8, drive fixture rotation by cylindrical grinder main shaft 5, drives cylindrical grinding wheel 6 to do in the horizontal direction to come and go and move, thereby carry out the cambered surface grinding of watt type product 4 by rotary main shaft 7; Until the arc surface of grinding reaches the demand that meets product.
This is practical by the rotation of fixture control product, carries out the grinding of arc surface by cylindrical grinding wheel 6, can effectively control the size of arc surface, has improved the precision of arc surface; Meanwhile, reduce the surperficial polishing scratch of arc surface; Reduce the use limitation of emery wheel; Same emery wheel can carry out grinding to different products, has reduced to a certain extent the use cost of emery wheel;
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done, within all dropping on protection domain of the present utility model.
