[0025] Based on the above technical solution, the displacement of the outer ring of the core shaft and the axially loaded bearing can be measured by installing the plate 2 at a right angle, and the displacement measurement of the same cross section of two sensors at different positions can be achieved.

[0028] Furthermore, the displacement sensor 3 passes through the long strip slot 11, and the displacement sensor 3 is fixed on the long strip slot 11 by two M8 nuts 4, the two M8 nuts 4 are respectively located on both sides of the long strip slot 11, and the two M8 nuts 4 are fastened by supporting the horizontal plate or the vertical plate; the workpiece to be tested 5 is placed in the space formed by the horizontal plate and the vertical plate, and the displacement sensor 3 performs contact or non-contact measurement on the workpiece to be tested.
[0029] Furthermore, the horizontal plate, vertical plate and connecting plate are fixedly connected to form an integrated structure, one end of the horizontal plate is connected to one end of the vertical plate to form a right-angle plate, the connecting plate is vertically arranged, and the bottom of the connecting plate is connected to the horizontal plate.
[0030] Furthermore, the T-hole slideway seat 8 is fixed to the mounting plate 1 of the BVT-8 vibration test bench by M6 bolts 7. There are two M6 bolts 7, which are distributed on both sides of the T-hole slideway seat 8 and correspond to the mounting holes of the test bench mounting plate 1.
[0031] The BVT-8 vibration test bench used in this embodiment is the BVT-8 vibration test bench of Hangzhou Bearing Test and Research Center; the displacement sensor used is the matching BVT displacement sensor of Hangzhou Bearing Test and Research Center.
[0032] The utility model relates to the field of sensor installation. In order to solve the problem of installing a displacement sensor on the basis of a BVT-8 vibration test bench without changing it, a test fixture that can perform multi-directional and multi-type measurements is designed. The device is mainly composed of a slideway crossbeam 9, a T-hole slideway seat 8, a right-angle position mounting plate 2, an M5 tightening screw 6, an M3 bolt 10, an M6 bolt 7, an M8 nut 4, etc. The device is easy to adjust, economical and applicable, can meet the same-section measurement of two vertical displacements of different core shafts or bearings, and improves the installation and positioning accuracy of the sensor.
[0033] First, install the vertical end of the connecting plate of the right-angle mounting plate 2 into the square connecting hole of the slide beam 9, and then use two M3 bolts 10 to connect and fix the right-angle mounting plate 2 and the slide beam 9. Then, insert the slide beam 9 horizontally into the T-hole slide seat 8. After adjusting to the appropriate position, tighten it with the M5 tightening screw 6, and then use the M6 bolt 7 to install and fix the T-hole slide seat 8 to the test bench mounting plate 1. Finally, install the displacement sensor 3 into the mounting hole of the right-angle mounting plate 2 and adjust the position of the displacement sensor 3 with the M8 nut 4.
[0034] The device provides a stable and adjustable fixture for displacement sensor measurement, realizes the simultaneous measurement of two sensors in the same section, and can measure the vibration of mandrels of various specifications and axially loaded bearing outer rings. Since the BVT 8 test bench itself has a vertical displacement adjustment function, but no lateral displacement adjustment function, the tooling can be adjusted horizontally by designing a lateral slideway, so that the displacement measurement of mandrels and bearings of different specifications can be met. Considering the requirement that the measurement directions of two sensors should be perpendicular to each other when measuring simultaneously, a right-angle mounting plate is designed to ensure that the two sensors are perpendicular to each other. Slender slots are opened in the same section of the horizontal plate and the vertical plate of the right-angle mounting plate, which facilitates the adjustability of the sensor position when measuring outer diameters of different sizes. The vertical end of the right-angle mounting plate is inserted into the square hole of the slideway crossbeam and fixed with bolts, and its shape and position tolerance and fit tolerance are strictly controlled. This separate assembly is selected instead of welding to avoid the problem of deformation caused by welding that affects the verticality, and it is also convenient for product processing.
