Description

Technical Field

[0001] The utility model belongs to the technical field of flatness detection, and in particular relates to a surface flatness quality inspection device for alloy steel plates. Background Art

[0002] The flatness detector uses optical methods to measure the surface characteristics of wafers, sapphire, Sic, Si, glass and other materials. It measures thickness, TTV, LTV, curvature, flatness, etc. without any contact. It can measure online and offline.

[0003] Since the support span of the conventional flatness tester is relatively large in order to ensure the standing stability, the storage box needs to accommodate the span, which causes the conventional flatness tester to occupy a relatively large storage space.

[0004] To this end, we proposed a surface flatness inspection device for alloy steel plates to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that conventional flatness detectors occupy a relatively large storage space, and proposes a surface flatness quality inspection device for alloy steel plates.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A surface flatness quality inspection device for alloy steel plates comprises a flatness detector body, a scale is slidably mounted on the lower part of the flatness detector body, a threaded seat is symmetrically fixedly connected to the side of the scale, and a magnetic bolt is mounted on the internal thread of the threaded seat. The threaded seat is placed on the target alloy steel plate, and the alloy steel plate is sucked tightly by the magnetic bolt so that the threaded seat stands stably on the alloy steel plate, and then the flatness detector body is slid and positioned for testing, and the overall thickness is reduced by the magnetic bolt adsorption and standing method, which is convenient for storage.

[0008] Preferably, a leather pad is fixedly connected to the lower end of the threaded seat, and the leather pad is used to increase the friction between the threaded seat and the alloy steel plate, thereby improving the stability of the device.

[0009] Preferably, the scale includes a scale body and a pad, and the pad is fixedly connected to the outer end of the scale body. The pad is used to pad the flatness detector body, so that the scale surface of the scale body does not contact the flatness detector body during sliding, thereby preventing the scale of the scale body from being worn flat.

[0010] Preferably, the magnetic bolt comprises a rotating block, a threaded shell and a magnet block, wherein the rotating block is fixedly connected to the upper end of the threaded shell, and the magnet block is fixedly connected to the lower part of the threaded shell. The rotating block drives the threaded shell to rotate, thereby changing the distance between the magnet block and the alloy steel plate, thereby changing the suction force of the magnet block on the alloy steel plate, and facilitating the user to adjust the suction force as needed.

[0011] Preferably, the magnetic bolt further comprises a knob, which is fixedly connected to the upper end of the rotating block. The knob is used to increase the length of the screwing lever of the rotating block, so as to facilitate manual screwing of the magnetic bolt.

[0012] Preferably, the outer circumference of the knob is provided with anti-skid patterns, so as to increase the friction between the magnetic bolt and the hand.

[0013] Preferably, the flatness detector body includes a casing, and the lower part of the casing is hollowed out and provided with a perforation, so that the flatness detector body and the scale can be slidably mounted through the perforation.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. Place the threaded seat on the target alloy steel plate, use the magnetic bolts to tighten the alloy steel plate, so that the threaded seat can stand stably on the alloy steel plate, and then slide and position the flatness tester body for testing. The overall thickness can be reduced by the magnetic bolts to facilitate storage.

[0016] 2. Use pads to pad the flatness tester body. When sliding, make sure the scale surface of the ruler does not contact the flatness tester body to prevent the scale of the ruler from being worn flat.

[0017] 3. Rotating the rotating block drives the threaded shell to rotate, changing the distance between the magnet block and the alloy steel plate, thereby changing the suction force of the magnet block on the alloy steel plate, making it convenient for users to adjust the suction force according to needs.
