Multi-point variable height combined positioning support mechanism and its support method

Abstract

The invention relates to a multi-point changeable-supporting-height combined positioning supporting mechanism. A plurality of positioning supporting wedges are arranged in a guiding sliding groove with a U-shaped opening; a supporting pin is arranged on each of the positioning supporting wedges; a horizontal guiding sliding wedge is arranged between every two positioning supporting wedges; a groove is formed in the end surface of each of the horizontal guiding sliding wedges adjacent to the positioning supporting wedges, and a horizontal spring is arranged in each of the grooves; a groove is formed in the bottom surface of each of the positioning supporting wedges, a vertical spring is arranged in each of the grooves, and the top surface of each of the vertical springs is supported on the top surface of the corresponding groove of the corresponding positioning supporting wedge; end plates are separately arranged at the two ends of the guiding sliding groove, a bolt is arranged on each of the end plates, and each of the bolts penetrates through the corresponding end plate to be fixedly pressed on the corresponding outer end surface of each of the horizontal guiding sliding wedges arranged at two ends. The supporting mechanism disclosed by the invention adopts the structure of multiple wedges and multiple supporting points, and can be automatically stretched by the elastic force of the springs, so that the situation that a supporting part of the mechanism is completely fitted with a supporting component is guaranteed, and the performances of accurate supporting and reliable supporting are guaranteed. The supporting method is fast and effective, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a multi-point variable height combined positioning support mechanism and a support method thereof, belonging to a support tool. Background technique [0002] In the mechanical processing of modern products, the products used for auxiliary support and positioning with variable surface height are limited by the product's own manufacturing tolerances, and cannot be completely and reliably attached to the supported products. Some large parts such as aircraft wall panels are being processed. Its own rigidity is poor, and support needs to be added at the weak part in the middle. Sometimes the workshop will set up some distributed supports at the lower part of the processed part, which needs to be judged by the experience of workers. Due to the limitation of the method, the effect of such supports is often not good, and it is impossible to determine whether they are supported or not.

Problems solved by technology

[0002] In the mechanical processing of modern products, the products used for auxiliary support and positioning with variable surface height are limited by the product's own manufacturing tolerances, and cannot be completely and reliably attached to the supported products. Some large parts such as aircraft wall panels are being processed. Its own rigidity is poor, and support needs to be added at the weak part in the middle. Sometimes the workshop will set up some distributed supports at the lower part of the processed part, which needs to be judged by the experience of workers. Due to the limitation of the method, the effect of such supports is often not good, and it is impossible to determine whether they are supported or not. In place, some use elastic support but fail to achieve the purpose of rigid locking, and some units with relatively strong funds use gas, hydraulic, electric and other forms, which often result in high cost and high cost due to the need to increase supporting facilities and resources
