Description

Technical Field

[0001] The present invention relates to the technical field of detection instruments, and particularly to a unidirectional paint scraping tester. Background Art

[0002] The paint scraping tester is a fully automatic test instrument used to detect the scratch resistance of the paint film on standard enameled round wires and flat wires. When the existing unidirectional paint scraping tester is performing detection, a controllable vertical force is applied through the loading of weights and the connecting rod mechanism connected thereto, simulating the mechanical pressure exerted on the enameled wire in actual applications, so as to accurately test the scratch resistance of the paint film under specific loads.

Each time the load is adjusted, the test process needs to be interrupted, the original weights need to be disassembled and rebalanced, and the single adjustment time can reach 1-2 minutes, seriously affecting the batch detection efficiency; moreover, factors such as the perpendicularity deviation of manual weight installation and the friction loss of the transmission rod will cause the actual acting force to deviate from the theoretical value.

[0028] In summary, a unidirectional paint scraping tester provided by the present application uses an industrial flat panel (i.e., the display screen 102) to control the operation of the overall system. During the test, as long as the required weight of the weight is entered, the instrument can automatically complete the following operations: lower the scraping blade 201, simulate the pressure on the scraping blade 201 under the weight of the weight by the adjusting mechanism 3, then perform paint scraping detection and shutdown, and automatically calculate and display the scraping force and average scraping force; the instrument uses a 10-inch liquid crystal display screen 102 to prompt the test steps, display the test results, is easy to operate, has high sensitivity, good repeatability, and accurate and reliable test results; and can automatically upload all test data and product information to the QME enameled wire quality management system for automatic storage and analysis, and manage and control the production process and quality of enameled wire at any time; it is applicable to enterprises and research institutions that produce or use enameled wire to detect and control the corresponding performance of enameled wire.

[0029] When the present invention is in use, the enameled wire is first loaded and installed. The specific operation is as follows: One end of the enameled wire to be detected is passed through the single scraping drill chuck 404 of one side clamping unit, and then passed through the positioning shaft tube 405 on one side by manual pulling, enters the positioning shaft tube 405 of the other side clamping unit through the area above the supporting plate, and then another single scraping drill chuck 404 is installed. Then, the straightening bolt 419 is rotated to drive the support frame 402 to move away from the bracket 401 to straighten and tension the enameled wire. Then, the end part of the enameled wire extending out of the single scraping drill chuck 404 is wound around the bottom of the paint-breaking bolt 418, and the paint layer at both ends is pressed and damaged by the rotation and pressing operation of the paint-breaking bolt 418, thereby realizing the conduction of the current and completing the installation of the enameled wire. Then, the paint scraping detection of the enameled wire is carried out. The specific operation is as follows: Turn on the instrument and reset the instrument through the control buttons 107 on the display screen 102 and the control panel; Move the wire supporting block 409 to the left or right to make the wire supporting block 409 in close contact with the enameled wire to be detected; Select round wire and input the corresponding weight of the weight according to the linear type selected in the built-in software interface of the display screen 102 according to the detection standard (this weight of the weight is the initial downward pressure of the scraping blade 201 when the paint scraping starts). Using the electrical connection post structure installed on the bracket 401, a stable DC test voltage is applied to the enameled wire. Then, the driving motor 317 drives the vertical lead screw 318 to rotate, driving the slider 315 to descend, compressing the compression spring 313, pressing down the adjusting frame 302, and driving the wire scraping knife 201 to press down, so that the tool tip contacts the enameled wire and continuously presses down until the reading of the force measuring sensor 410 reaches the set weight value of the weight. Then, the shifting motor 211 is started, driving the horizontal lead screw 212 to rotate, and further driving the slide seat 213 and the balance ring 215 and the scraping knife assembly thereon to move horizontally. During the horizontal movement, as the driving motor 317 continuously drives the adjusting frame 302 and the wire scraping knife 201 to press down, the pressure of the wire scraping knife 201 on the enameled wire gradually increases, causing the reading of the force measuring sensor 410 to gradually increase until a corresponding scraping signal is generated when the specimen is scraped. At this time, the reading of the force measuring sensor 410 is recorded as the scraping force of this paint scraping test. The driving motor 317 and the shifting motor 211 both stop operating, and the wire scraping knife 201 completes a paint scraping test. Then, the driving motor 317 and the shifting motor 211 rotate in the reverse direction, driving the wire scraping knife 201 to lift and reset and return; At this time, the flipping motor 408 is started, driving the intermediate gear 407 to rotate, and further driving the transmission shaft 415 and the transmission gear 413 to rotate, and further driving the positioning shaft tubes 405, the positioning disks 403, and the single drill chucks 404 in the two clamping units to rotate synchronously, realizing the rotational adjustment of the enameled wire. When the enameled wire rotates 120 degrees, the flipping motor 408 stops, and a paint scraping test is carried out again. The scraping force is displayed through the display screen 102. After repeating the paint scraping test three times, the average scraping force is displayed and recorded as the scraping force of the enameled wire to be tested.

[0030] In one embodiment, the difference between this embodiment and the above embodiment is that it is used to realize the paint scraping test of the flat wire, and the tool tip used is the flat wire scraping tool tip 204; Please refer to Figure 7 and Figure 8 , the flat wire scraping tool tip 204 includes a fixing part 2041 and an adjusting part 2042.
