the first clamping body and the second clamping body are both provided with clamping surfaces in arc structures, and the center of the clamping surface of the first clamping body and the center of the clamping surface of the second clamping body are positioned on the same straight line;
a plurality of arc-shaped clamping grooves are formed in the two ends of the clamping surface respectively, and the arc-shaped clamping grooves in the first clamping body correspond to the arc-shaped clamping grooves in the second clamping body.
Furthermore, a plurality of mounting holes are formed in the axial direction of the first clamping body or the axial direction of the second clamping body, and the mounting holes are symmetrical about the central line of the clamping surface.
Furthermore, a plurality of screw holes are formed in the radial direction of the first clamping body or the radial direction of the second clamping body, the screw holes are symmetrical relative to the center of the clamping surface, and the screw holes correspond to the mounting holes.
Further, the centers of the arc-shaped clamping grooves are positioned on the same straight line.
Furthermore, the first clamping body and the second clamping body are integrally of a plate-shaped structure.
The utility model discloses following beneficial effect has: the arc-shaped clamp for the circular workpiece provided by the utility model has reliable structure and stable clamping, and realizes reliable clamping of the circular workpiece through the mutual cooperation of the first clamping body and the second clamping body; a user can place the circular workpiece in the corresponding arc-shaped clamping groove according to the use requirement, and the center of the circular workpiece is ensured to be constant and inconvenient through the limiting clamping of the first clamping body and the second clamping body, and the clamping is reliable and stable; in the clamping process, the circular workpiece is in full contact with the first clamping body and the second clamping body through arc surfaces, so that the contact area of the workpiece and the clamping piece is increased, the damage of the clamping acting force to the workpiece is reduced, the workpiece is not easy to shift in the clamping process, and the clamping reliability is improved.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a top view of the present invention;
the reference numerals shown in fig. 1 to 2 are respectively expressed as: 1-a first clamping body, 2-a second clamping body, 3-a clamping surface, 4-an arc-shaped clamping groove, 5-a mounting hole and 6-a screw hole.
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1 to 2, the arc-shaped clamp for a circular workpiece includes a first clamping body 1 and a second clamping body 2 disposed opposite to the first clamping body 1, wherein the first clamping body 1 and the second clamping body 2 have the same shape and size. First holding body 1 and second holding body 2 are symmetrical shape, and circular workpiece is located between first holding body 1 and second holding body 2, when using, draws close to the center through first holding body 1 and second holding body 2, realizes the spacing centre gripping to circular workpiece, guarantees that circular workpiece's center is invariable.
The first clamping body 1 and the second clamping body 2 are both provided with clamping surfaces 3 in arc structures, and the center of the clamping surface 3 of the first clamping body 1 and the center of the clamping surface 3 of the second clamping body 2 are positioned on the same straight line; a plurality of arc centre gripping grooves 4 have been seted up respectively to the both ends of clamping face 3, and arc centre gripping groove 4 on the first clamping body 1 is corresponding with arc centre gripping groove 4 on the second clamping body 2. The clamping surface 3 of the first clamping body 1 and the clamping surface 3 of the second clamping body 2 are matched to form a circular cavity for placing a circular workpiece. The circular end face of the circular workpiece is clamped in the arc-shaped clamping groove 4, and the circular workpiece is limited. The centers of the arc-shaped clamping grooves 4 are positioned on the same straight line. Arc centre gripping groove 4 has different diameters and width, and the user can be according to the size of a dimension of circular workpiece, selects the arc centre gripping groove 4 of looks adaptation to carry out the centre gripping operation to circular workpiece, the effectual performance that has improved anchor clamps. When arc centre gripping groove 4 and circular workpiece centre gripping cooperation, circular workpiece and arc centre gripping groove 4 are the contact of pitch arc face, the effectual area of contact that has increased between circular workpiece and the anchor clamps, make the centre gripping effort obtain the diffusion distribution, avoided stress concentration, reduced the damage of anchor clamps to the work piece.
