Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0014] figure 1 It is a structural representation of the present invention. The present invention proposes a multi-degree-of-freedom tooling fixture, which includes a fixed installation shaft 2 and a base 1 symmetrically distributed on both sides of the fixed installation shaft 2. The base 1 is fixed on the fixed installation shaft 2. A rotating arm 5 is arranged on the base 1. 1 is provided with a driving gear 4 inside, and the driving gear 4 is fixedly provided with a matching transmission main shaft 6, the transmission main shaft 6 is rotationally connected with one end of the rotating arm 5, and the other end of the rotating arm 5 is provided with a movable claw 7, a fixed hand Claw 8, rad...

Abstract

The invention discloses a multi-degree-of-freedom tool fixture. A base is fixed on a fixed mounting shaft, and is provided with a rotating arm; a driving gear is arranged in the base; a matched transmission main shaft is fixedly arranged on the driving gear; the transmission main shaft is rotationally connected with one end of the rotating arm; a movable jaw, a fixed jaw and a radial guide rail are arranged at the other end of the rotating arm; the radial guide rail is fixedly arranged on the inner side of the rotating arm; the fixed jaw is fixed on the radial guide rail; and the movable jaw is slidingly connected with the radial guide rail. The driving gear is matched with the transmission main shaft to drive the rotating arm to put workpieces or worktables to be clamped between the movable jaw and the fixed jaw; a screw cap and a ball screw are tightened to precisely adjust the distance between the movable jaw and the fixed jaw to clamp the workpieces or the worktables; and through symmetric distribution of the base in space, multi-degree-of-freedom clamping of the workpieces or worktables is realized, so that the positioning precision is radically improved, and the assembly precision is improved.

Description

technical field [0001] The invention relates to a multi-degree-of-freedom fixture, belonging to the technical field of fixtures. Background technique [0002] The existing machining and assembly accuracy firstly depends on whether the positioning of the tooling is accurate. The existing tooling fixtures focus more on the positioning of the plane, but cannot accurately adjust the positioning accuracy. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, solve the above technical problems, and propose a multi-degree-of-freedom tooling fixture. [0004] The present invention adopts the following technical solution: a multi-degree-of-freedom tooling fixture, which is characterized in that it includes a fixed installation shaft and bases symmetrically distributed on both sides of the fixed installation shaft, and the base is fixed on the fixed installation shaft. A rotating arm is arranged on the base, and a drivi...
