Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of product detection, and in particular to a tail wing folding and over-bore wing span integrated device. BACKGROUND

[0002] In today's large-scale, high-efficiency production environment, enterprises generally pay attention to the degree of automation of the production process in order to improve production efficiency and ensure product quality, seek simpler and faster solutions, and minimize the use of tooling and product transfer. However, in the current detection of product tail wings, there is no dedicated automated equipment, and the existing method is manual and semi-automatic, with multiple station conversion work, which is divided into 5 steps, namely tail wing folding, slot oiling, installation of product fixing tooling, over-bore detection, and wing span detection. Details are as follows:

[0003] (1) The product is hoisted onto the folding table by the crane, and the product is vertically placed. The semi-automatic device is started, and the tail wing is folded by rotating the nylon wheel to press the tail wing using a motor-driven worm gear reducer;

[0004] (2) The oil is applied to the slot by manual brushing;

[0005] (3) The product fixing tooling is installed manually, which is in the form of two half-hexagonal frames, and is tightened by bolts to form a hexagonal shape to fix the product shape, which prevents the tail wing from unfolding during subsequent transfer and over-bore process;

[0006] (4) The product is hoisted to the over-bore station by the crane, and the over-bore gauge is vertically passed through for detection;

[0007] (5) The product is transferred to the wing span station by the crane, the wing span tooling is installed, the tail wing tooling is in the form of an internal hexagonal flat plate, the fixing tooling is removed, and the wing span detection is performed manually by workers with good physical strength and strength, which quickly pulls out the wing span tooling to make the wing span tooling quickly separate from the product, and the tail wing unfolds instantly.

[0008] The existing technical solution has the following defects:

[0009] (1) The degree of automation is low, and oiling, over-bore, and wing span need to be completed manually, folding needs to be assisted by manual operation, and it cannot be folded in place at one time. The product needs to be frequently transferred to different stations.

[0010] (2) The quality consistency of manual operation is difficult to guarantee, such as the accuracy of oiling, the stress parameter control of over-bore, and the rapid detection of wing span.

[0011] (3) Manual operation is dangerous, and during the wing span detection process, the worker needs to quickly pull out the tooling, and the tail wing may injure the hand if not careful. During the product transfer process, the product needs to be frequently hoisted, and there is a risk of falling off the hoist and product.

[0012] (4) Manual operation is strong, the existing process is manually operated, the work is complex, the wing span detection rapid pull-up tool needs explosive force to overcome the friction between the product and the tool, and the physical quality of the operator is required.

[0013] (5) Consuming many tools, the existing method needs to install tool auxiliary products to maintain the product posture during the multi-station turnover process, a large number of tools are needed, and the installation and disassembly of the tools are needed, the tool itself is an auxiliary tool for product installation, which can cause material loss and work efficiency waste.

[0014] Therefore, it is an urgent problem to design a device capable of automatically completing the tail wing folding, notch oiling, bore detection and wing span detection. SUMMARY
