Description

TECHNICAL FIELD

[0001] The utility model relates to ceramic fiber processing technical field, specifically a kind of ceramic fiber gasket is measured thick device. BACKGROUND

[0002] Ceramic fiber is a kind of fibrous lightweight refractory material, with light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and resistance to mechanical vibration and other advantages, so it has been widely used in machinery, metallurgy, chemical industry, petroleum, ceramics, glass, electronics and other industries.

[0003] The Chinese utility model patent with publication number CN209927044U discloses a ceramic fiber product thickness measuring device on January 10, 2020, which belongs to the technical field of special material thickness measuring device. The ceramic fiber product thickness measuring device includes a reference plate, a load device, and a measuring device. The load device is connected to the rope body through the load weight. The rope body moves through the pulley block and the limiting mechanism. The connecting piece connected to the pressure head pulls the dial indicator to display data. The product thickness on the reference plate is measured. The utility model makes the rope body turn through the limiting mechanism and the pulley block, slows down the movement of the rope body and the connecting rod, stabilizes the measurement value; the overload device and the measuring device are separated, which prevents the test rod of the dial indicator in the measuring device from deviating from the stress direction; the load device and the test rod are connected through the connecting piece, and the connecting piece is directly connected to the pressure head, which avoids the measurement rod from being unable to align with the center of the metal disc; the reference plate is designed in multiple specifications according to the actual thickness of the measured ceramic fiber product, which can measure the thickness of various types of ceramic fiber products.

[0004] However, the above-mentioned disclosed scheme has the following disadvantages: the thickness measurement of the ceramic fiber product in the prior art is still mainly measured by using a dial indicator. This method is only suitable for ceramic fiber products with high hardness. Because the dial indicator needs to be in contact with the measured object to produce pressure changes, external force can cause the ceramic fiber gasket to deform, making the dial indicator measurement inaccurate.

[0021] Please see Figs. 1-3 As shown, a thickness measuring device for ceramic fiber pads includes a fixed base plate 1 for stable connection; countersunk holes 2 are symmetrically opened on the fixed base plate 1; a first fastener 3 is inserted into the countersunk holes 2; a fixed shaft 4 is threaded onto the first fastener 3, so that the fixed shaft 4 is vertically and stably connected in the countersunk holes 2; a stepped slide tube 5 is slidably sleeved on the fixed shaft 4; a measuring pressure plate 6 and a limiting ring 7 are rotatably sleeved on the stepped slide tube 5; a traction rope 8 is fixedly connected to the stepped slide tube 5; a locking groove 9 is opened on the fixed shaft 4 corresponding to the traction rope 8. Through the symmetrical fixed shaft 4, the stepped slide tube 5 and the traction rope 8, a static equilibrium state is formed, so that when measuring the ceramic fiber pad, the ceramic fiber pad is placed on the upper surface of the fixed base plate 1, and then the stepped slide tube 5 is manually moved down to make the measuring pressure plate 6 tangent to the upper surface of the ceramic fiber pad, and the thickness of the ceramic fiber pad can be read at this time, so that the thickness change caused by gravity pressing the ceramic fiber pad will not affect the accuracy of the measurement.
