Description

Technical Field

[0001] The invention relates to the field of clamps and jigs, and in particular to a variable-angle high-load clamp and jig with a plurality of V-shaped grooves. Background Art

[0002] V-shaped grooves are used in clamps. The two side walls of the V-shaped groove play a squeezing role, and the final combined force can keep the clamped part stable. However, the V-shaped groove is not a movable clamp structure, but an integrated part, so its flexibility is poor when used. Summary of the invention

[0003] The problem to be solved by the present invention is to provide a variable-angle high-load clamp with multiple V-grooves, which utilizes the V-grooves to clamp and limit the external workpiece. At the same time, the fixture has the ability to rotate and fix the top plate, so that the V-grooves have the ability to fine-tune the angle, thereby enriching the freedom of the fixture.

[0004] In order to solve the above problems, the present invention provides a variable angle high load clamp with multiple V-grooves. In order to achieve the above purpose, the technical solution adopted by the present invention to solve the technical problem is:

[0005] A variable-angle high-load clamp with multiple V-grooves comprises: a top plate, the edge of which is provided with a plurality of V-grooves, the top plate is provided with two arc holes penetrating the top plate, the arc holes themselves are arc-shaped, the two arc holes are arranged in mirror symmetry, the shortest distance between the two arc holes is the line connecting the same ends of the two arc holes; the inner wall of the arc hole is provided with a step surface; a base block is provided with an internal threaded hole, the internal threaded hole and the arc hole are assembled by bolts; the vertical downward projection of the V-groove does not intersect with the base block.

[0006] The beneficial effect of adopting the above technical solution is that the main design of the fixture is two arc-shaped holes. By slightly rotating the top plate in the horizontal plane, the angle of the V-groove can be adjusted, giving the fixture more degrees of freedom. When the top plate is rotated and adjusted, it is equivalent to the position of the internal threaded hole in the arc-shaped hole changing, but the bolt can always be assembled with the internal threaded hole and the arc-shaped hole. The step surface is for contacting and tightening with the head of the bolt.

[0007] As a further improvement of the present invention, the arc trajectory of a single arc-shaped hole is an arc with a central angle less than 90°.

[0008] The beneficial effect of adopting the above technical solution is that the length of the arc hole does not need to be too long, that is, the orientation angle of the V-shaped groove can be fine-tuned.

[0009] As a further improvement of the present invention, the arc lines of the two arc-shaped holes overlap with the same circle.

[0010] The beneficial effect of adopting the above technical solution is that the rotation adjustment of the top plate is smoother, and the opening of the internal threaded hole can always be exposed in the arc hole.

[0011] As a further improvement of the present invention, the base block includes a bottom block and a pad, the pad is located between the bottom block and the top plate, the internal threaded hole is located in the pad, and the bottom block is provided with a countersunk hole for assembly with the pad.

[0012] The beneficial effect of adopting the above technical solution is that the bottom block and the pad thicken the vertical thickness of the base block. The bottom block can be fixed to the frame, and the spatial position of the bottom block can be always fixed.

[0013] As a further improvement of the present invention, the edge of the bottom block coincides with the vertical projection contour of the edge of the backing plate.

[0014] The beneficial effect of adopting the above technical solution is to ensure that the base block is a rectangular parallelepiped as a whole.

[0015] As a further improvement of the present invention, the top plate has a convex edge portion that is not in contact with the pad, the V-shaped grooves are all located in the convex edge portion, and the root of the convex edge portion contacts two adjacent straight edges of the pad edge.

[0016] The beneficial effect of adopting the above technical solution is that the V-shaped grooves in the convex edge portion themselves have V-shaped grooves that are oriented perpendicular to each other.

[0017] As a further improvement of the present invention, the widths of the V-shaped grooves on the convex edge are not equal.

[0018] The beneficial effect of adopting the above technical solution is that V-shaped grooves of different widths are suitable for clamping cylindrical workpieces of different thicknesses.

[0019] As a further improvement of the present invention, threaded blind holes are provided between adjacent V-shaped grooves, and the axes of the threaded blind holes are parallel to the depth direction of the V-shaped grooves.

[0020] The beneficial effect of adopting the above technical solution is that the threaded blind hole can be fixed with an external bolt, and two bolts together with a stop rod can semi-permanently limit the clamped workpiece on the clamping fixture.

[0021] As a further improvement of the present invention, the direction of the top angle of the bottom of the widest V-groove among the plurality of V-grooves passes through the centroids of the two arc-shaped holes respectively, and the straight edge of the top plate where the widest V-groove is located has only one V-groove.

[0022] The beneficial effect of adopting the above technical solution is that the V-shaped groove with the widest width also has the largest corresponding supporting force behind it. BRIEF DESCRIPTION OF THE DRAWINGS
