Description

Technical Field

[0001] The utility model relates to the technical field of detection and positioning, in particular to a detection and positioning device for rubber bearings. Background Technique

[0002] The isolation rubber bearing is formed by alternately laminating thin steel plates and thin rubber plates and vulcanizing under high temperature and high pressure. The isolation rubber bearing can not only ensure the vertical stiffness and bearing capacity, but also greatly reduce the horizontal stiffness, enabling the building to have seismic isolation performance. When the rubber bearing leaves the factory, a detection device is required to detect the parameters of the compressive elastic modulus and shear elastic modulus of the rubber bearing. Usually, a press is used to perform shear detection on the rubber bearing. During the detection, two rubber bearings are placed at the upper and lower positions of the horizontal shear bearing plate, and the two rubber bearings are aligned and positioned, and the press is used to perform shear detection on the two rubber bearings.

[0003] In order to facilitate the detection and positioning of two rubber bearings during detection, the prior art has made many improvements to the detection and positioning device for rubber bearings. For example, the patent with the publication number CN220104665U discloses an auxiliary tool for detecting the shear elastic modulus of rubber bearings, which includes a bearing plate, and positioning blocks are provided on the bearing plate. The positioning blocks straddle the opposite sides of the bearing plate, and the side walls of the positioning blocks are for the side walls of the rubber bearings to abut against. After the rubber bearings on both sides of the bearing plate abut against the positioning blocks respectively, their relative positions can be determined with higher precision, eliminating the need for manual visual inspection or pushing, etc., improving the operation efficiency and precision.

By starting the driving unit 11, the driving unit 11 drives the two moving plates 7 to move towards each other simultaneously. When the moving plates 7 move, they drive a plurality of moving rods 8 to move simultaneously. If the rubber bearing body 4 is not at the central position of the detection table 1, a plurality of elastic pressing rollers 10 simultaneously squeeze the two rubber bearing bodies 4, and the two rubber bearing bodies 4 simultaneously move towards the central position of the detection table 1 until the plurality of pressing rollers 10 simultaneously press the two rubber bearing bodies 4.

And the main controller can be a conventional known device such as a computer that plays a control role.

[0032] Embodiment Two

[0033] Please refer to Figures 1-3 , this embodiment includes the above embodiment. Among them, the driving unit 11 includes a driving motor 12 fixedly installed at one end of the bearing seat 6. Both lower ends of the two moving plates 7 are fixedly connected with sliders 13. A chute 14 adapted to the sliders 13 is provided on the upper side of the bearing seat 6. A bidirectional lead screw 15 is rotatably connected in the chute 14. The bidirectional lead screw 15 penetrates through the two sliders 13 and is threadedly connected with the sliders 13.

And the main controller can be a conventional known device such as a computer that plays a control role.

[0036] Embodiment III

[0037] Please refer to Figures 2-5 , this embodiment includes all the above embodiments. Among them, it further includes: a moving groove 16 adapted to the moving rod 8 is penetrated through the side surface of each moving plate 7, an adjusting groove 18 communicating with the outside is penetrated through the opposite side walls of each moving groove 16, threaded columns 17 adapted to the adjusting groove 18 are arranged on both sides of each moving rod 8, a limiting ring 19 is threadedly connected to the side surface of one end of the threaded column 17 away from the moving rod 8, a limiting block 20 is fixedly connected to one end of each threaded column 17 close to the moving rod 8, limiting grooves 21 adapted to the limiting block 20 are opened on both sides of each moving rod 8, a rectangular block 22 adapted to the adjusting groove 18 is fixedly connected to the side surface of each threaded column 17, a polygonal limiting hole 23 is penetrated through one end of each moving rod 8 close to the rubber support body 4 and the pressing frame 9, a detachable inserting rod 24 is inserted into each limiting hole 23, and each limiting groove 21 penetrates through one end of the moving rod 8 away from the rubber support body 4.

After the height positions of the moving rods 8 are adjusted, tighten the limiting ring 19 to fix the positions of the moving rods 8. The rectangular block 22 is adapted to the adjusting groove 18, which can prevent the moving rod 8 from rotating. When the rubber support body 4 to be positioned is too large or too small, due to the limitations of the detection table 1 and the bearing seat 6, it may be impossible to position the rubber support body 4. The horizontal position of the moving rod 8 can be adjusted. When the moving rod 8 moves horizontally, the limiting block 20 slides in the limiting groove 21. After the horizontal direction of the moving rod 8 is adjusted, tighten the limiting ring 19 to fix the position of the moving rod 8. And when it is necessary to replace the moving rod 8, the moving rod 8 can be pulled out through the limiting groove 21 penetrating one end of the moving rod 8. At the same time, the pressing frame 9 can be replaced according to the size of the rubber support body 4 to be detected. Pull out the inserting rod 24 inserted in the limiting hole 23, and the pressing frame 9 can be removed, improving the application range of the overall device.
