Description
Calibration-free mounting structure of included angle arrangement equipment Technical Field The invention mainly relates to the technical field of general structural layout and installation modes, in particular to a calibration-free installation structure of included angle arrangement equipment. Background In reality, there are a plurality of equipment that have the precision requirement to the mounted position, install the condition on contained angle structure basis. The equipment has higher positioning (or calibration) requirements on the accuracy of the installation position of each equipment on the installation basis, and the relative installation position accuracy between the two included angle installation equipment also has higher positioning (or calibration) requirements. Take a typical two-device angle installation as an example, see fig. 1. The specific equipment A and the equipment B are respectively installed and fixed on the installation surfaces of the two included angles of the installation foundation through 4 installation bolts. Because the precision calibration is required to be carried out on the installation positions of the single equipment and the two equipment, 4 permanent calibration targets are designed and manufactured on the outer surfaces of the equipment A and the equipment B so as to meet the requirement that after the final equipment is assembled, the final absolute position precision and the final relative position precision of the equipment A and the equipment B can be calibrated through special calibration equipment. See fig. 2. However, there are cases where the devices a and B are required to be frequently removed and replaced, and there are cases where the relative positions of the two device mounting bases are changed due to long-term structural deformation or accumulation of deformation caused by external force of the mounting bases, so that repeated calibration of the devices a and B is required. This will tend to increase the additional calibration time, frequency and overall cost, especially if the installation base is a floating platform or is affected by the actual environment where it is extremely difficult to perform calibration. Disclosure of Invention Aiming at the problems that two devices (or a plurality of devices) installed on the installation foundation of an included angle structure are required to be calibrated for the first time and the subsequent calibration for a plurality of times caused by the replacement of the devices or the deformation of the installation foundation, the invention provides a calibration-free installation structure of included angle arrangement devices, which aims at omitting the calibration requirement of the devices after the first installation and the multi-frequency calibration work in the subsequent whole life cycle, and simultaneously greatly reducing the implementation difficulty of calibration for certain special installation platforms/scenes. In order to achieve the purpose, the invention provides a calibration-free mounting structure of an included angle arrangement device, wherein an auxiliary positioning corner fitting mounting sink is reserved at the included angle position of a mounting base; The auxiliary positioning corner fitting is provided with a special auxiliary positioning corner fitting, and an auxiliary positioning corner fitting positioning pin and an auxiliary positioning corner fitting mounting hole are formed in the auxiliary positioning corner fitting; And a device mounting screw hole and a device mounting positioning pin hole are formed in the position, corresponding to and matched with the auxiliary positioning corner fitting, of the mounting device, and a device appearance target point is reserved. Further, the auxiliary positioning corner fitting is installed and fixed in an installation sinking groove structure on an installation foundation; And installing and positioning the installation equipment on two sides through the equipment installation positioning pin holes and the auxiliary positioning corner fitting positioning pins on the installation equipment respectively, and fastening and fixing the installation equipment and the auxiliary positioning corner fitting installation holes through the equipment installation screw holes on the installation equipment by using fastening bolts. Further, the respective machining precision and the relative position machining precision of all the auxiliary positioning corner piece positioning pins and the auxiliary positioning corner piece mounting holes on the auxiliary positioning corner pieces are uniquely determined by the high-precision digital die machining equipment.
