Embodiment

[0042] An adaptive fixture suitable for complex curved surface processing includes a fixing device and a clamping device.

[0043]The fixing device is composed of a fixing frame 1 and a bottom plate 3, and the two are assembled by four identical fixing screws 2. The clamping device is made up of sealing sleeve 7, sucker 8, slide bar 9, spring 10, pneumatic cylinder 5 and piston 6 of equal quantity, and this equal quantity is 12. Wherein the piston 6 is installed on the pneumatic cylinder 5, which can realize the reciprocating linear motion of the piston. There is an air suction pipe on the suction cup 8, which is used to suck the curved surface tightly. The suction cup 8 is connected with the slide bar 9 through a ball joint, which can realize the arbitrary rotation of the suction cup within a certain angle. After many groups of suction cups 8 and slide bars 9 are installed, they are evenly installed in the chute 13 of the fixed mount 1. Pneumatic cylinder 5 cooperates with ...

Abstract

The invention discloses a self-adaption clamp suitable for complex hook face machining and a use method of the self-adaption clamp suitable for complex hook face machining. The self-adaption clamp suitable for complex hook face machining comprises a fixing frame, multiple vertical positioning parts and multiple horizontal positioning parts, wherein the fixing frame is provided with a horizontal board, and multiple sliding grooves are evenly formed in the horizontal board; each vertical positioning part comprises a sliding rod and a sucker, and the sliding rods are vertically arranged, and are installed in the multiple sliding grooves; the suckers are connected with the tops of the sliding rods through spherical joints, and are used for adsorbing to-be-positioned complex hook face parts; each horizontal positioning part is located at one side of one corresponding vertical positioning part in a one-to-one corresponding mode, each horizontal positioning part comprises a pneumatic cylinder and a piston, and each pneumatic cylinder is located at one side of one corresponding sliding rod; and the pistons are located between the pneumatic cylinders and the sliding rods, and are used for compressing the sliding rods nearby by adjusting the telescopic lengths of the pistons, so that displacement of the sliding rods in vertical directions is limited. The problems that in existing methods, the clamp production cost is high, the work reliability is low, an application range is small, and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of processing and manufacturing, and in particular relates to an adaptive fixture suitable for complex curved surface processing and a use method thereof. Background technique [0002] In the process of mechanical processing and manufacturing, in order to strengthen the processing object and position the processing object in the correct position to receive construction or inspection, it is usually necessary to use fixtures. Reasonable use of fixtures can not only improve processing quality, but also broaden the processing range and types of machine tools, and also play an important role in shortening production preparations and improving enterprise production efficiency. There are a large number of unstructured complex curved surfaces and thin-walled structures in aerospace structural parts. Such structures have complex shapes, relatively low rigidity, large machining allowances, and poor manufacturability. ...
