Description
Technical Field
The utility model relates to an anchor clamps technical field, concretely relates to quick detach piece expanded joint positioner and expanded joint device.
Background
The expansion joint process of the quick-release part is in the last procedure of production of the component framework, 24 quick-release components are uniformly distributed on one component framework, the flatness of an expansion joint forming surface and the size of an expansion joint bulge directly determine the success or failure of production of the whole component framework.
The prior process method comprises the following steps: and (4) processing an integral expansion joint tooling plate, and processing 24 corresponding mounting hole positions on the clamp plate. In the clamping process, 24 quick-release assemblies are simultaneously arranged on a clamp plate, a tensioning sleeve is arranged behind the clamping plate and is rotated by 90 degrees, so that the working surface of the quick-release assembly can be borne on a bearing ring of the quick-release assembly, and each quick-release assembly is supported against the tensioning sleeve by four spring set screws. To this end, the quick release assembly is positioned and locked onto the tooling fixture plate. And then sequentially expanding the assembly and the framework guide tube together by using an expansion gun. After the expansion joint is completed, the tensioning sleeve is sequentially rotated back by 90 degrees, and the expansion joint tooling plate can be separated from the quick-release assembly.
In practical production, the mode of clamping 24 quick-release assemblies and expanding connection at one time has the following defects in long-term operation: the positioning surface is too small due to the appearance of the disassembled assembly, so that the assembly is easy to deflect on a tooling plate in the installation process.
The existing method for solving the problem is as follows: after 24 quick-release components are all installed on a positioning plate, the quick-release components are integrally conveyed to a three-coordinate platform for detection, the planeness of the back positioning surface of the quick-release components is calculated by measuring the planeness of four supporting blocks of a guide pipe sleeve of each quick-release component, and the flatness is manually adjusted according to a deviation value, the adjusting method is that four fastening screws surrounding the quick-release components are respectively screwed, and the locking force of each quick-release component is different due to the fact that 96 spring jackscrews are arranged on the whole tooling plate and the jacking force of each jackscrew is different. Because the measured surface and the positioning surface have machining errors, the flatness of the end surface of the 24 groups of quick-release components is required to be 0.15mm after the whole component framework is produced, and the flatness of a single component on the mounting surface is controlled within 0.03 (the dimension is controlled to be 0.025 in actual production) according to a one-third principle.
However, the whole adjusting process of the method needs a lot of labor hours, and only by the hand feeling and experience of debugging personnel, the method can not be quantized, and the standard for guiding production is formed. And in actual production operation, the quick-release parts are influenced by expansion joint force and can shorten the axial dimension, but the deformation quantity of each quick-release component is different, so that an expansion joint plate for clamping 24 groups of quick-release components at one time can be distorted along with the expansion joint sequence during operation, the flatness requirement of 0.15 of the end surface of the quick-release component after expansion joint is finished cannot be ensured, and the scrapped result of the whole component framework is finally caused.
