Abstract
The invention discloses a clamp for eliminating eccentric moment, which comprises a clamp body (2) and an adjusting clamp (4; 5), wherein at least one fixing lug (1; 3) is arranged on the side surface of the clamp body (2), a ball (11; 31) is arranged on the fixing lug (1; 3), two mutually parallel plane structures are arranged on the adjusting clamp (4; 5), and the ball (11; 31) is clamped between the two plane structures. The fixture for eliminating the eccentric moment has a simple structure and reasonable arrangement, and is accurate in centering and dislocation-free by arranging the round balls on the side surfaces of the fixture body and matching the round balls by utilizing two mutually parallel plane structures.
Description
Technical Field
The invention relates to a clamp for eliminating eccentric moment.
Background
In the prior art, the fixture generates eccentric moment in the rotating process because of asymmetric installation, so that the problem occurs in the use process of the workpiece.
Therefore, a new clamp for eliminating the eccentric moment is required to solve the above-mentioned problems.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a clamp for eliminating eccentric moment.
The above purpose is achieved by the following technical scheme:
a clamp for eliminating eccentric moment comprises a clamp body (2) and an adjusting clamp (4; 5), wherein at least one fixing lug (1; 3) is arranged on the side face of the clamp body (2), a ball (11; 31) is arranged on the fixing lug (1; 3), two mutually parallel plane structures are arranged on the adjusting clamp (4; 5), and the ball (11; 31) is clamped between the two plane structures.
Further, the clamp body (2) is a cylindrical clamp or a circular clamp.
Furthermore, one end of the adjusting clamp (4; 5) is provided with a groove, two sides of the groove are respectively provided with a first bolt and a second bolt, two opposite end surfaces of the first bolt and the second bolt are planes parallel to each other, and the first bolt and the second bolt respectively prop against two sides of the ball (11; 31). The plane opposite to the first bolt and the second bolt are matched with the ball, so that the purpose of eliminating eccentric moment is conveniently realized.
Furthermore, the number of the fixing lugs (1; 3) is 2. The two fixing lugs arranged on the side face of the clamp body can effectively eliminate eccentric moment in the rotating process.
The beneficial effects are that: the fixture for eliminating the eccentric moment has a simple structure and reasonable arrangement, and is accurate in centering and dislocation-free by arranging the round balls on the side surfaces of the fixture body and matching the round balls by utilizing two mutually parallel plane structures.
Drawings
FIG. 1 is a schematic diagram of a clamp for eliminating eccentric moment;
FIG. 2 is a perspective view of a clamp with an adjustment clamp for eliminating eccentric moments;
fig. 3 is a top view of the clamp with the adjustment clamp for eliminating the eccentric moment.
Detailed Description
The present invention is further illustrated in the accompanying drawings and detailed description which are to be understood as being merely illustrative of the invention and not limiting of its scope, and various modifications of the invention, which are equivalent to those skilled in the art upon reading the invention, will fall within the scope of the invention as defined in the appended claims.
Referring to fig. 1, 2 and 3, the fixture for eliminating eccentric moment of the present invention includes a fixture body 2 and an adjusting fixture 4;5, at least one fixing lug 1 is arranged on the side surface of the clamp body 2; 3, fixing the lug 1;3 are provided with round balls 11;31, adjusting the clamp 4;5 are provided with two mutually parallel plane structures, namely a sphere 11;31 are sandwiched between two planar structures. Wherein the clamp body 2 is a cylindrical clamp or a circular clamp.
Preferably, the clamp 4 is adjusted; 5, a groove is formed in one end of the ball bearing, a first bolt and a second bolt are respectively arranged on two sides of the groove, two opposite end faces of the first bolt and the second bolt are planes parallel to each other, and the first bolt and the second bolt respectively prop against the ball 11; 31. The plane opposite to the first bolt and the second bolt are matched with the ball, so that the purpose of eliminating eccentric moment is conveniently realized.
Preferably, the ear 1 is fixed; the number of 3 is 2. The two fixing lugs arranged on the side face of the clamp body can effectively eliminate eccentric moment in the rotating process.
The principle of the invention: in the rotation process, two plane structures which are parallel to each other prop against the sphere, the surface and the sphere are in point contact, and the connecting line of the contact points passes through the sphere center for the clamp body, so that the pressing force can be counteracted in the direction, and the clamp is stable in clamping and accurate in centering without dislocation.
The fixture for eliminating the eccentric moment has a simple structure and reasonable arrangement, and is accurate in centering and dislocation-free by arranging the round balls on the side surfaces of the fixture body and matching the round balls by utilizing two mutually parallel plane structures.
