Description

Technical Field

[0001] The utility model belongs to the technical field of testing instruments, and in particular relates to a paint layer thickness testing tool. Background Art

[0002] After mechanical parts are manufactured, they generally need to be sprayed with paint on their surface. The main purpose of spraying paint is to prevent mechanical parts from rusting. According to the different uses and application fields of mechanical parts, the thickness and uniformity of the paint layer of mechanical parts have corresponding control requirements. Therefore, after spraying paint on mechanical parts, the thickness of the paint layer needs to be inspected. Currently, a special handheld paint film thickness gauge is used to measure the thickness of the paint layer of mechanical parts. However, since this measurement method uses a handheld measuring instrument, there is no unified standard for the operator's holding posture and technique, which can easily lead to missed inspections or repeated inspections.

[0003] In the prior art, the patent document with the publication number "CN203772246U" discloses a positioning and measuring device for the paint thickness on the surface of the spoke plate of a rail wheel. The characteristic is that the device is composed of a compass orientation positioner, a spoke plate outer sample plate and a spoke plate inner sample plate. The compass orientation positioner is composed of a compass, a main rod frame and a core column. The compass is fixed on the bearing, and the bearing is mounted on the main rod frame. The compass rotates freely around the main rod frame; the lower edges of the inner and outer sample plates of the spoke plate correspond to the inner and outer shapes of the wheel spoke plate respectively, and one end of the sample plate is vertically inserted into the compass with a slot, and the lower edge is attached to the inner and outer sides of the spoke plate; the paint thickness gauge is aligned with the detection point marked on the spoke plate sample plate for detection. This patented technology provides a unified positioning reference for the operator to use a paint film thickness gauge to measure the thickness of the paint layer, which improves the accuracy and reliability of the measurement results to a certain extent. However, when using a paint film thickness gauge for measurement, the operator needs to read the corresponding readings for the paint layer thickness of each component. In the mass production process, it is often only necessary to qualitatively determine whether the paint layer thickness meets the requirements, without the need to read the paint layer thickness of each component. Therefore, the above measurement method has the defects of a long measurement process, high labor intensity for the operator, and inability to adapt to mass production operations. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a paint layer thickness inspection tool.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a paint layer thickness inspection tool, comprising an upper hoop block, a lower hoop block and a pressure rod, wherein the upper hoop block is fixedly connected to the lower hoop block, and the bottom edge of the upper hoop block and the top edge of the lower hoop block overlap with each other, a lug is provided on the side surface of the upper hoop block, one end of the pressure rod is hinged with the lug by using a pin shaft, and the other end of the pressure rod extends outward.

[0007] One side surface of the upper hoop block is used as a reference surface, one side surface of the lower hoop block is used as a limiting surface, the lug is arranged on the reference surface, and the inclination angle of the limiting surface relative to the reference surface is 0° to 60°.

[0008] The upper hoop block is a rectangular body.

[0009] The lower hoop block is a trapezoidal body.

[0010] The pressure rod is also fixedly connected to one end of the wing plate, and the other end of the wing plate extends outward.

[0011] The length direction of the compression rod and the length direction of the wing plate are perpendicular to each other.

[0012] The number of the wing plates is a pair, and the pair of wing plates are arranged on the left and right sides of the pressure rod.

[0013] The lugs are in a pair, and the pair of lugs are arranged on the left and right sides of the pressure rod.

[0014] The upper hoop block and the lower hoop block are fixedly connected by bolts.

[0015] The beneficial effect of the utility model is that: by adopting the technical scheme of the utility model, after the mechanical parts are sprayed with paint, a piece with typical characteristics on the surface of the mechanical parts is cut off as a test piece, the front end part of the test piece is clamped between the upper hoop block and the lower hoop block, and then a torque is applied to the pressure rod to make the rear end part of the test piece rotate or bend relative to its front end part, and the operator then observes the condition of the paint layer at the bending part with the naked eye. If the paint layer is chipped or peeled after the test piece is bent, it indicates that the paint layer thickness is insufficient, the paint layer adhesion is not strong, and the quality of the paint layer on the surface of the corresponding mechanical parts is not qualified. This measurement method only makes a qualitative judgment on whether the paint layer thickness is qualified, thereby reducing the inspection time and the labor intensity of the operator. This measurement method is more suitable for inspection work in mass production. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 2 It is a top view of the utility model.

[0019] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0020] like Figure 1 , Figure 2 As shown, the utility model provides a paint layer thickness inspection tool, including an upper hoop block 1, a lower hoop block 2 and a pressure rod 3, the upper hoop block 1 is fixedly connected to the lower hoop block 2, and the bottom edge of the upper hoop block 1 and the top edge of the lower hoop block 2 coincide with each other, a lug 4 is provided on the side of the upper hoop block 1, one end of the pressure rod 3 is hinged to the lug 4 using a pin 5, and the other end of the pressure rod 3 extends outward.

[0021] According to the technical solution of the utility model, after the mechanical parts are sprayed with paint, a piece with typical characteristics on the surface of the mechanical parts is cut off as a test piece, the front end part of the test piece is clamped between the upper hoop block and the lower hoop block, and then a torque is applied to the pressure rod to rotate or bend the rear end part of the test piece relative to its front end part. The operator then observes the condition of the paint layer at the bending part with the naked eye. If the paint layer is chipped or peeled after the test piece is bent, it indicates that the paint layer thickness is insufficient, the paint layer adhesion is not strong, and the quality of the paint layer on the surface of the corresponding mechanical parts is not qualified. This measurement method only makes a qualitative judgment on whether the paint layer thickness is qualified, thereby reducing the inspection time and the labor intensity of the operator. This measurement method is more suitable for inspection work in mass production.

[0022] Specifically, one side surface of the upper hoop block 1 is used as the reference surface 6, one side surface of the lower hoop block 2 is used as the limiting surface 7, the lug 4 is arranged on the reference surface 6, and the inclination angle of the limiting surface 7 relative to the reference surface 6 is 0° to 60°. The upper hoop block 1 is a rectangular body. The lower hoop block 2 is a trapezoidal body. By adopting the technical solution of the utility model, after the corresponding test piece on the mechanical part is inspected, since the test piece has been bent and damaged, it helps to avoid the situation of missing or repeated inspection of the thickness of the paint layer on the surface of the mechanical part.

[0023] In addition, the pressure rod 3 is also fixedly connected to one end of the wing plate 8, and the other end of the wing plate 8 extends outward. The length direction of the pressure rod 3 and the length direction of the wing plate 8 are perpendicular to each other. There is a pair of wing plates 8, and the pair of wing plates 8 are arranged on the left and right sides of the pressure rod 3. The wing plate 8 increases the load force area between the pressure rod 3 and the workpiece, which helps the operator to bend the test piece cut from the mechanical parts more easily.

[0024] In addition, the lugs 4 are a pair, and the lugs 4 are arranged on the left and right sides of the pressure rod 3. The upper hoop block 1 and the lower hoop block 2 are fixedly connected by bolts 9.
