Problems solved by technology

[0002] The paddle sleeve is one of the important parts in the assembly process of the propeller. The paddle sleeve is a thin-walled shell part. The machining accuracy and the clamping and positioning method of the inner hole during the processing are relatively high. If the clamping force is too large, it will easily damage the part. , the clamping force is too small and the clamping effect cannot be achieved, so the existing clamping and positioning tools are not very suitable

Embodiment Construction

[0013]The present invention will be further described below with reference to the accompanying drawings and specific examples.

[0014]Such asfigure 1 ,figure 2 ,image 3 withFigure 4As shown, the present embodiment includes a main body 3, a clamping shaft 2, a nut, a tie rod 9, a spring 5, a jacket 4, a tapered block 6, and a push-pull block 7 with a connecting rod. The outer circle of the main body 3 matches the inner hole of the workpiece 12, extending into a tapered shape, the left end portion has a circle projection 13, and the center is opened with the inner hole I14 that matches the outer circle of the pulley 9, the right end of the inner hole I14 The diameter is large to accommodate the spring 5. An inner hole II15 is perpendicular to the inner holes I14 in the protrusions of the main body 3 and in combination with the clamping shaft 2. The pull rod 9 is in the position of the inner holes I14 and II15, and the clamping shaft mounting hole 16 is formed, the left end is thick, and...

Abstract

The invention discloses a clamping and positioning tool for an inner hole of a thin-wall shell part. The clamping and positioning tool comprises a main body, a clamping shaft, a nut, a pull rod, a spring, a clamping spring, a conical block and a push-pull block with a connecting rod, wherein a propeller root outer sleeve is sleeved on the main body and an outer circle of the clamping spring , the nut is screwed down, the clamping shaft moves upwards, the left end of the clamping shaft is provided with a conical surface used in cooperation with the conical surface of the left end wall of a clamping shaft mounting hole in the pull rod, the lower end face of the conical surface presses the pull rod to move leftwards, the pull rod drives the conical block to move leftwards, the conical block compresses the spring and jacks the clamping spring at the same time, the clamping spring clamps an inner hole of the propeller root outer sleeve for positioning; and after the propeller root outer sleeve is machined, the nut is unscrewed, the clamping shaft moves downwards and is separated from the pull rod, the conical block moves rightwards under the action of the spring, the clamping spring retracts inwards and resets, and the propeller root outer sleeve is taken down. The clamping and positioning tool is accurate in positioning, proper in clamping force, free of damage to the surface of an inner hole of a part and convenient in use.

Description

Technical field[0001]The present invention relates to a thin-walled housing part in the inner hole clamping positioning tool.Background technique[0002]The paddle is one of the important components in the propeller assembly. The paddle holders belong to the thin-walled housing parts, the processing accuracy, and the processing of the inner holes are relatively high, and the intensity of the clamping is too easy to damage parts. , The intensity of the clamping is too small, and the existing clamping positioning tool is not very suitable.Inventive content[0003]It is an object of the present invention to solve the above problems in the prior art, providing a positioning accurate, suitable, and has no damage to the inner hole surface of the part, and the inner holes in which the thin-walled housing parts are clamped.[0004]In order to achieve the above object, the technical solution of the present invention is: a thin-walled housing part in the inner hole clamping positioning tool, includ...
