Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Generally, the product to be calibrated is placed on the calibration device, and then rotation in various directions is performed according to design requirements, and photographing calculation is performed from different directions to correct the anti-shake capability of the product. The calibration equipment in the related art does not have anti-seismic performance, so that the calibration accuracy of the calibration equipment is reduced when the calibration equipment faces vibration, such as unavoidable influence caused by factory working conditions of personnel walking, forklift operation and the like near a calibration station, and calibration distortion is caused.

Referring to fig. 1 to 3, the present application discloses a calibration device for calibrating a product to be calibrated. The alignment apparatus includes a mounting frame 100 having a positioner 110 therein. The placing platform 200 is disposed on the mounting frame 100 and connected to the positioner 110. A plurality of shock absorption feet 300 are arranged on one side of the mounting frame 100 departing from the placing platform 200 at intervals.

In this application, the mounting bracket 100 is the installation basis of the parts such as the placing platform 200 and the shock absorption foot 300, so as to improve the integration level of the device of this application. The positioner 110 can drive the placing platform 200 to rotate at various angles to calibrate the product to be detected, for example, by connecting a motor or other devices that can drive rotation.

The apparatus of the present application is typically placed on a calibration station in a factory floor, with the shock absorbing foot 300 side of the calibration apparatus resting on the ground. When the device is used specifically, the placing platform 200 is used for placing a product to be detected, and the placing platform 200 can rotate along with the positioner 110, so that the positioner 110 can adjust the levelness of the placing platform 200, and the aim of calibrating the product to be detected is fulfilled. Specifically, the positioner 110 drives the product to be detected to rotate through the placing platform 200, and then performs photographing calculation in different directions, thereby achieving the purpose of calibration.

When the positioning platform is influenced by vibration and the like, the vibration from the seismic source is transmitted to the damping feet 300 through the ground, the damping feet 300 absorb the energy of the vibration in a deformation mode and the like, and the vibration cannot be transmitted to the positioning platform 200 continuously, so that the aim of damping is achieved, and the calibration precision is further ensured.

Further, as for the specific structure of the shock absorbing foot 300, the shock absorbing foot 300 may be provided as a spring, a shock absorbing elastic pad, or the like. The shock absorbing foot 300 provided by the present application may include a support pillar 310 and a shock absorbing base 320, and the shock absorbing base 320 includes a shock absorbing part 321 and an annular support part 322. The annular support portion 322 surrounds the shock absorbing portion 321, and the annular support portion 322 and the shock absorbing portion 321 enclose a shock absorbing chamber 323. The mounting block 100, the support pillar 310, the shock absorbing portion 321, and the shock absorbing chamber 323 are sequentially disposed along a gravity direction, and the mounting block 100 is supported by the shock absorbing portion 321 through the support pillar 310.

In this way, the annular support 322 will be in contact with the ground. And the shock absorbing chamber 323 is surrounded by the annular support portion 322 and located between the ground and the shock absorbing portion 321. Thus, in the case where the calibration device is subjected to a shock, at least one of the shock absorbing portion 321 and the annular support portion 322 is elastically deformed, and the volume of the shock absorbing chamber 323 is changed according to the elastic deformation. It can be seen that the shock absorbing foot 300 has the advantages of effectively absorbing energy generated by shock, better preventing the shock from being further transmitted to the mounting frame 100, and further ensuring the calibration accuracy.

More specifically, the vibration damping mount 320 may include a protective layer and an elastic skeleton 303. The elastic skeleton 303 is provided in the protective layer. The first portion of the elastic frame 303 and the first portion of the protective layer form a shock absorbing portion 321, and the second portion of the elastic frame 303 and the second portion of the protective layer form an annular support portion 322.

The plurality of elastic support bars are disposed around the rotation axis of the vibration-damping mount 320, and the rotation axis of the vibration-damping mount 320 coincides with the direction of gravity. I.e., the elastic support strips form a more warp-like structure layout in the cushion pan 320. The deformation is more easily generated when the shock is received in the arrangement, and the energy of the shock can be more effectively absorbed, so that the shock absorption effect is improved.

Further, the protective layer may include a first protective layer 301 and a second protective layer 302. The second protective layer 302 encloses a damper chamber 323. The elastic framework 303 is covered and disposed on one side of the second protection layer 302 departing from the shock absorption cavity 323, and the first protection layer 301 is covered and disposed on one side of the elastic framework 303 departing from the shock absorption cavity 323. This design facilitates the installation of the resilient skeleton 303.

Furthermore, the first protective layer 301 may be made of natural rubber, so that the comprehensive performance is high and a good mask protection effect can be achieved. The second protective layer 302 can be made of butyl rubber, so that the damping performance and the air tightness are high, the air leakage of the damping cavity 323 can be prevented, and the auxiliary supporting effect on the elastic framework 303 is achieved.

Further, shock absorbing base 320 may further include elastic bending portion 324. The annular support portion 322 is elastically connected to the shock absorbing portion 321 by an elastic bending portion 324. The third portion of the elastic skeleton 303 and the third portion of the protection layer form an elastic bending portion 324, and when the calibration apparatus is vibrated, the elastic bending portion 324 is elastically deformed, specifically, when the elastic bending portion 324 is elastically deformed, the curvature radius thereof is changed.

Elasticity bending portion 324 receives the main deformation position of vibrations for vibration damping mount 320, and deformation takes place easily for this kind of structure, has better absorbing effect to the energy that vibrations produced, can strengthen shock attenuation foot 300 shock attenuation effect like this, and the deformation of different degrees also can be carried out in cooperation elasticity bending portion 324 to shock attenuation portion 321 and annular supporting portion 322 of course, and here is no longer detailed.
