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 tooling fixture, the base is fixed on a fixed installation shaft, a rotating arm is arranged on the base, a driving gear is arranged inside the base, and a matching transmission main shaft is fixedly arranged on the driving gear, and the transmission main shaft and the One end of the rotating arm is rotatably connected, and the other end of the rotating arm is provided with a movable gripper, a fixed gripper, and a radial guide rail. Sliding connection with radial guide rails. The rotating arm is driven by the cooperation of the driving gear and the transmission spindle, and the workpiece or table to be clamped is placed between the movable gripper and the fixed gripper, and the movable gripper and the fixed gripper are precisely adjusted by tightening the nut and the ball screw. The distance between the claws enables it to clamp the workpiece or workbench, and through the symmetrically distributed base in space, the multi-degree-of-freedom clamping of the workpiece or workbench is realized, so as to improve the positioning accuracy from the source, and then improve the assembly accuracy .

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...
