Description

Technical Field

[0001] The utility model relates to the technical field of paint detection, in particular to a paint detection mechanism. Background Technique

[0002] Paint, also known as coating, is a chemical mixture coating that can firmly cover the surface of an object and serve functions such as protection, decoration, marking, and other special purposes. During the production process of paint, it is necessary to detect the adhesion, toughness, and elasticity of the paint. Currently, for the detection of paint adhesion, the method mainly used is the scratch combined with tape test. First, a cross-grid shape is scratched on the plate coated with paint to form small squares, then a tape is pasted on the scratched part and quickly torn off to observe whether there is paint peeling off. To evaluate the toughness and elasticity of the paint when it is subjected to collision or impact, an impact test is required. The impact test is mainly carried out by a stamping machine. The plate coated with paint is placed under the stamping machine, and a certain impact force is applied to observe whether the paint on the plate cracks or peels off.

[0003] Currently, when detecting the adhesion and impact of paint, the two can usually only be carried out separately, and it is impossible to simulate the complex stress conditions that the paint undergoes in actual applications. Therefore, there may be certain deviations in the test results and it is impossible to accurately reflect the true performance of the paint.

[0004] To solve the above problems, a paint detection mechanism is proposed in this application. Content of the Utility Model

[0005] Based on the technical problems existing in the background technique, the utility model proposes a paint detection mechanism.

[0006] A paint detection mechanism proposed by the utility model includes a base;

[0007] On both sides of the top of the base, fixing blocks are installed, and elastic clamping members for workpiece positioning are installed on both of the fixing blocks;

[0008] Above the base, a top seat is installed, and a stamping member for stamping the workpiece is installed at the bottom of the top seat;

[0009] On the far - away sides of the two fixing blocks, guide wheel members are installed, and second wire wheels are installed on the tops of the two fixing blocks. The bottom end of the stamping member is connected with two pull ropes, and the two pull ropes respectively bypass the second wire wheels on the two fixing blocks and the guide wheel members and are connected to the far - away ends of the two elastic clamping members.

[0010] Preferably, the elastic clamping member includes a pull rod. Through holes are formed in the middle of the two fixed blocks. The two pull rods horizontally slide through the two through holes respectively. U-shaped blocks are installed at the ends of the two pull rods close to each other. Springs are sleeved on the pull rods between the fixed blocks and the U-shaped blocks, and the two ends of the springs are respectively connected to the fixed blocks and the U-shaped blocks. A clamping part for workpiece positioning is installed on the U-shaped block.

[0011] Preferably, the clamping part includes a screw rod and a clamping disc. A clamping opening is formed in the U-shaped block. A threaded hole communicating with the clamping opening is formed at the top of the U-shaped block. The clamping disc is arranged in the clamping opening. The screw rod is threadedly passed through the threaded hole, and the bottom end of the screw rod is rotatably connected to the top of the clamping disc.

[0012] Preferably, the stamping member includes a cylinder and a stamping column. An assembly channel is formed in the middle of the top seat. The cylinder is installed in the assembly channel. The stamping column is vertically arranged between the base and the top seat, and the stamping column is connected to the cylinder and driven by the cylinder to move closer to or away from the base.

[0013] Preferably, the guide wheel member includes a roller frame. The two roller frames are respectively installed on the opposite sides of the two fixed blocks. The two roller frames are respectively located below the two pull rods. First guide wheels are rotatably installed on the two roller frames, and the two first guide wheels are respectively located at the ends of the two pull rods away from each other.

[0014] Preferably, one ends of the two ropes are respectively connected to the two sides of the bottom end of the stamping column. The two ropes respectively bypass the two first guide wheels and are connected to the ends of the two pull rods away from each other.

[0015] The above technical solution of the present utility model has the following beneficial technical effects:

[0016] By arranging the elastic clamping member, the stamping member and the ropes, the workpiece coated with paint can be clamped between the two elastic clamping members, and then the workpiece can be stamped by moving the stamping member downward. During the downward movement of the stamping member, the two ropes can be driven to move on the corresponding guide wheel members and the second guide wheels and respectively pull the two elastic clamping members away from each other to realize the pulling of the workpiece, and then observe whether the paint on the workpiece falls off. This structure can simultaneously detect the adhesion, toughness and elasticity of the paint by pulling during stamping, so as to provide a more comprehensive and accurate evaluation of the paint performance.

[0017] By performing stamping and pulling detection simultaneously, the composite stress condition of the paint can be simulated, making the test results closer to the real scenario and improving the accuracy and reliability of the test. Description of the Drawings

It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0022] As Figure 1 shown in Figure 2 a paint detection mechanism proposed by the present utility model includes a base 1;

[0023] On both sides of the top of the base 1, fixed blocks 2 are installed, and elastic clamping members 3 for workpiece positioning are installed on both fixed blocks 2. The elastic clamping member 3 includes a pull rod 31. Through holes are formed in the middle parts of the two fixed blocks 2, and the two pull rods 31 slide horizontally through the two through holes respectively. U-shaped blocks 32 are installed at the closer ends of the two pull rods 31. A spring 33 is sleeved on the pull rod 31 between the fixed block 2 and the U-shaped block 32, and both ends of the spring 33 are connected to the fixed block 2 and the U-shaped block 32 respectively. A clamping portion 34 for workpiece positioning is installed on the U-shaped block 32. The clamping portion 34 includes a screw 341 and a clamping disc 342. A clamping opening is formed in the U-shaped block 32, a threaded hole communicating with the clamping opening is formed at the top of the U-shaped block 32, the clamping disc 342 is arranged in the clamping opening, the screw 341 is threaded through the threaded hole, and the bottom end of the screw 341 is rotatably connected to the top of the clamping disc 342.

[0024] Above the base 1, a top seat 4 is installed, and a stamping member 5 for workpiece stamping is installed at the bottom of the top seat 4. The stamping member 5 includes a cylinder 51 and a stamping column 52. An assembly channel is formed in the middle of the top seat 4. The cylinder 51 is installed in the assembly channel. The stamping column 52 is vertically arranged between the base 1 and the top seat 4, and the stamping column 52 is connected to the cylinder 51 and driven by the cylinder 51 to approach or move away from the base 1.

[0025] On the side away from each other of the two fixed blocks 2, a guide wheel member 6 is installed; the guide wheel member 6 includes a roller frame 61, and the two roller frames 61 are respectively installed on the side away from each other of the two fixed blocks 2. The two roller frames 61 are respectively located below the two pull rods 31. A first wire wheel 62 is rotatably installed on each of the two roller frames 61, and the two first wire wheels 62 are respectively located at the ends away from each other of the two pull rods 31; on the top of the two fixed blocks 2, a second wire wheel 7 is installed.

[0026] At the bottom end of the stamping part 5, two pull ropes 8 are connected. The two pull ropes 8 respectively bypass the second wire wheels 7 on the two fixed blocks 2 and the guide wheel member 6 and are connected to the ends away from each other of the two elastic clamping members 3. One end of each of the two pull ropes 8 is connected to both sides of the bottom end of the stamping column 52. The two pull ropes 8 respectively bypass the two first wire wheels 62 and are connected to the ends away from each other of the two pull rods 31.

[0027] It should be noted that: the two ends of the workpiece coated with paint can be respectively clamped in the two U-shaped blocks 32, and then the screw 341 is rotated downward to push the clamping disc 342 to clamp the workpiece, so that the workpiece coated with paint is fixed between the two U-shaped blocks 32.

Then, observe whether the paint on the workpiece falls off. This structure can detect the adhesion, toughness and elasticity of the paint simultaneously by pulling during the stamping process, so as to provide a more comprehensive and accurate evaluation of the paint performance.

[0028] By carrying out the stamping and pulling detections simultaneously, the composite stress condition of the paint can be simulated, making the test results closer to the real scenario and improving the accuracy and reliability of the test.

[0029] In a specific embodiment, after the workpiece is detected, the screw 341 can be loosened upward to make the clamping disc 342 away from the workpiece, releasing the limit on the workpiece. Then, the workpiece can be taken out from between the two U-shaped blocks 32. Subsequently, the cylinder 51 is used to drive the stamping column 52 to move upward.
