Abstract

The utility model discloses an auxiliary device for testing thickness of coatings, comprising a rotating body installed on a pedestal, a template bearing bracket and a standard steel ball, wherein the shape of the rotating body is similar to a toy diabolo; shaft levers on two ends of an axis are installed on a bearing seat; the shaft lever at one end is connected with an electric motor shaft; the template bearing bracket is adjacent to the rotating body; the standard steel ball is placed between a sliding plate of the template bearing bracket and a V-shaped circumferential concave groove of the rotating body. During an operation process, a coating testing template is adhered and fixed on the sliding plate of the bearing plate and an electric motor is started to drive the rotating body to rotate such that the rolling standard steel ball is capable of performing positioning friction of the testing template and gradually milling a regular small circular ring; and then the diameter L1 and the diameter L2 on two ends of the circular ring are read by a reading microscope; the precise thickness D of the coating can be calculated according to a formula. The device is simple in structure, capable of precisely measuring the thickness of the coating of the plane testing template of various materials.

Description

Coated layer thickness measuring servicing unit

Technical field

The utility model relates to a kind of coated layer thickness measure servicing unit, and what be specifically related to is a kind of servicing unit that the coated layer thickness of plane test sample plate is measured.

Background technology

Existing coated layer thickness measurement equipment mainly is divided into types such as eddy current thickness meter, electromagnetic thickness tool and supersonic thickness meter.These thicknessmeters all can be done direct measurement to the coated layer thickness on the object, also can measure the coated layer thickness of plane coated layer test sample plate.All there is following deficiency in they: 1. pair measured material has certain limitation, generally requires coated layer or matrix to have conduction or magnetic conductivity; 2. measuring operation is comparatively complicated; 3. receive the restriction of measuring principle, measuring accuracy is not high; 4. cost an arm and a leg.

Summary of the invention

The purpose of the utility model is to provide a kind of simple structure, operation and the servicing unit that can measure the coated layer thickness of multiple material easily.

The technical scheme that realizes above-mentioned purpose is: a kind of coated layer thickness measure servicing unit; Solid of revolution, model carrier and standard steel ball by being installed on the pedestal are formed; The shape of said solid of revolution is similar in appearance to a toy diabolo, and the axostylus axostyle at axis two ends is installed on the bearing seat, and an end axostylus axostyle is connected with motor shaft through shaft coupling; Model carrier and solid of revolution are adjacent, said standard steel ball be shelved on the model carrier slide plate and solid of revolution " V is " between the font circumferential groove.

Said model carrier by base with forms on one side with hinged carrying group plate in base edge and the support adapter behind the carrying group backboard, the elevation angle of carrying group plate can be through the support adapter adjusting.

Said carrying group plate is made up of base plate and a slide plate of a band edge frame, and slide plate is positioned at the positive frame of base plate, and the high and low position of slide plate can be regulated screw adjusted through the up-down of base plate upper end.

Said steel ball is wimet steel ball or chromium plating steel ball.

The operation steps and the principle of work of this device are: plane coated layer test sample plate card is closed on the slide plate that is fixed on loading plate; Again the standard steel ball of known radii R be shelved on solid of revolution " V is " in the font circumferential groove and steel ball is abutted against on the coating aspect of test sample plate; Regulate the base plate elevation angle of loading plate and the height of slide plate then simultaneously, make steel ball being abutted against on test sample plate a little be positioned at point previously selected to be ground.Starter motor drives solid of revolution and rotates; The standard steel ball of this moment just rolls in the groove of solid of revolution; The standard steel ball that rolls just positions friction to the mill point of treating of test sample plate; After friction after a while; Test sample plate can be ground with a little segment, promptly forms the small circle ring of a rule on the coated layer, is placed on test sample plate under the reading microscope then; Read the two ends diameter L1 and the L2 numerical value of annulus on the coated layer, at last according to formula:

can calculate the accurate thickness D of coated layer.

The utility model simple structure, operation easily, cost is low, can measure the plane test sample plate coated layer thickness of multiple material, and measurement is accurate, precision is higher, and it is used to be more suitable for the experiment of school and scientific research institution.

Embodiment

Be described further below in conjunction with accompanying drawing with to the utility model.

To shown in Figure 3, the main member of the utility model coated layer thickness measure servicing unit is solid of revolution 2, model carrier and standard steel ball 8 like Fig. 1.Standard steel ball 8 is generally wimet steel ball or chromium plating steel ball; The shape of solid of revolution 2 is similar in appearance to a toy diabolo, and the centre has that " " font circumferential groove 3, the axostylus axostyle 4 at its axis two ends are installed on the bearing seat 5 that is fixed on the base 1 V, and an end axostylus axostyle is connected with 7 in motor on the pedestal 1 through shaft coupling 6; The model carrier is adjacent with solid of revolution 2, the plate face of model carrier and the parallel axes of solid of revolution 2; Standard steel ball 8 be shelved on the model carrier positive with solid of revolution " V " and between the font circumferential groove 3, formation standard steel ball 8 with " V " and the cell wall of font circumferential groove 3 contact and with the positive surface contact state of model carrier.

The model carrier by base 9 with form with hinged carrying group plate in base 9 edges and the support adapter 13 behind the carrying group backboard on one side.Base 9 is fixed on the pedestal 1 and is positioned at the below of solid of revolution 2; Carrying group plate is made up of base plate 10 and a slide plate 11 of a band edge frame; Slide plate 11 is positioned at the frame in base plate 10 fronts; The high and low position of slide plate 11 can be regulated through the up-down set screw 12 of base plate 10 upper ends, and the elevation angle of carrying group plate can be regulated through the set screw on the support adapter 13.

As shown in Figure 4; When the standard steel ball 8 that rolls is grinding on the surface of test sample plate 14 after a bead lacks; Promptly form the small circle ring of a rule on the coated layer; Be placed on test sample plate 14 under the reading microscope; Read the two ends diameter L1 and the L2 numerical value of annulus on the coated layer, because the radius R of standard steel ball 8 is known, therefore can be according to formula:

calculates the accurate thickness D of coated layer.
