Abstract

The utility model discloses an adjustable anchor clamps for three-dimensional measurement of small-size aviation blade. The utility model discloses to less and the fixed, unable scheduling problem of adjusting of size of the anchor clamps that use the structured light projection mode to measure small-size aviation blade now, designed an adjustable anchor clamps that is used for three-dimensional measurement of small-size aviation blade. The utility model consists of four modules which can move along the direction limited by respective T-shaped guide rail devices, and aviation blades with different sizes are adjusted and clamped by respective adjusting bolts; the bottom main module is a disc base and is provided with four threaded holes for connecting and fixing. Can stabilize the clamping to the small-size aviation blade of equidimension not in certain specification range through the adjusting bolt of adjustment top and horizontal direction to the screw hole that accessible disc base had is connected with corresponding measuring desk, with the stability of further improvement aviation blade when measuring.

Description

Adjustable clamp for three-dimensional measurement of small aviation blade

Technical Field

The utility model relates to a design of small-size anchor clamps especially relates to the adjustable anchor clamps design aspect of using the small-size aviation blade of structured light measurement.

Background

When the morphology of a small aviation blade or other precision parts is measured by using structured light, the aviation blade needs to be vertically placed and kept in a stable state, so that the effect and the precision of grating projection measurement are ensured. And current blade measurement anchor clamps kind is less, mostly is fixed size, can not adjust the type anchor clamps or directly adopts the sticky tape mode of pasting to fix the blade on the measuring table, carries out projection measurement with structured light. Therefore, the clamp can stably clamp small aviation blades of different sizes in a certain specification range, has certain universality and stability, meets the requirement of a structured light measurement process, can well solve the problems, and has high practicability.

Disclosure of Invention

In order to overcome the not enough of above-mentioned prior art, the utility model provides an adjustable anchor clamps for small-size aviation blade three-dimensional measurement makes things convenient for the scientific research or the social production process of the small-size aviation blade of structured light measurement.

The utility model adopts the technical proposal that: the fixture is mainly formed by combining four main body modules, and is provided with one T-shaped guide rail device at the bottom in the horizontal direction, and one T-shaped guide rail device at the left and right in the vertical direction; the corresponding modules move and are fastened according to the direction limited by the T-shaped guide rail device by screwing adjusting bolts in the horizontal direction and the vertical direction so as to clamp small aviation blades with different sizes in a certain specification range; the main module at the bottom is integrated with the disc base, and the disc base is provided with four threaded holes for fixing on the measuring table.

The utility model has the advantages that, compare with prior art, the beneficial effects of the utility model are that can adjust the distance between level, the vertical direction module through the adjusting bolt of rotatory level and vertical direction, realize the small-size aviation blade centre gripping of certain specification within range to the elasticity of centre gripping is adjusted to the rotatory each adjusting bolt of accessible, thereby improves the commonality of this anchor clamps. The bottom main module and the disc base are integrated and are provided with four threaded holes, so that the fixture is convenient to install and fix on a measuring table, and the stability of the fixture is effectively improved.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

fig. 1 is a three-dimensional view of the overall structure of the clamp. The bottom sub-module, the top main module and the top sub-module move in the direction limited by respective T-shaped guide rail devices by rotating the adjusting bolts in the horizontal direction and the vertical direction, so that the clamping device is suitable for clamping small aviation blades with different sizes in a certain specification range.

In fig. 2, the top sub-module (4) and the top main module (9) have the same specification. The top adjusting bolts (3) are connected with the corresponding bottom modules, move up and down in the direction limited by the vertical T-shaped guide rail device (1) in the vertical direction and are screwed tightly by the top adjusting bolts (3); the bottom sub-module (5) is connected with the bottom main module (8) through a horizontal adjusting bolt (6), and moves in the horizontal direction according to the direction limited by the horizontal T-shaped guide rail device (2) at the bottom, and finally is screwed through the horizontal adjusting bolt (6), so that stable clamping of the small aviation blade is finally realized. Wherein the base of the bottom main module (8) is disc-shaped, has larger stability and is provided with four base threaded holes (7) for connecting with corresponding measuring tables so as to further improve the stability of the clamp.

Fig. 9 is a front view of the clamping effect of a small aviation blade of a certain model, according to the size of the base of the aviation blade, the small aviation blade is clamped by adjusting the top adjusting bolt (3) and the horizontal adjusting bolt (6), and the blade base is clamped by screwing each adjusting bolt, so that the effect of stable clamping is achieved.
