Description

Technical Field

[0001] The invention belongs to the technical field of quality detection, and in particular relates to a quick detection instrument for the quality of zinc plating of power grid equipment. Background Art

[0002] The quality inspection of galvanizing of power grid equipment is a comprehensive evaluation process. During the appearance inspection, the galvanized layer should be smooth, and there should be no burrs, nodules and excess lumps at the overlap. Burrs and excess lumps are allowed at non-overlap, but the height and area must be controlled within a certain range. According to the different components and materials of the power grid equipment, the thickness requirements of the galvanized layer are different. At present, most methods are to use professional hammer or drop hammer equipment to strike the galvanized layer of the power grid equipment, and observe whether the galvanized layer has bulges, peeling, etc., so as to evaluate the adhesion of the galvanized layer.

[0003] Traditional galvanized layer hammer test equipment and methods are mainly designed for objects with regular shapes, but in actual applications, many objects have irregular shapes, which brings challenges to the galvanized layer hammer test. Due to their complex shapes, irregular-shaped objects may need to increase the number of hammer strikes or change the hammer strike position to fully evaluate the adhesion of the galvanized layer, making it difficult to ensure the accuracy of the hammer test point, thus affecting the accuracy of the test results. In addition, irregular-shaped objects require more adjustment steps in the hammer test, which increases the complexity and time-consuming nature of the operation. At the same time, due to the irregular shape, the hammer head may lose control during the hammer test, increasing safety risks.

[0033] Working principle: When the device is in use, a person holds the handle on the top of the hammer test machine housing 1 and presses it downward, so that the lower pressing seat 2 below is against the surface of the workpiece to be tested. At this time, the bottom contact of the zinc coating thickness gauge 3 contacts the workpiece and sends a low-frequency signal. When the transmitted signal passes through the coating, the intensity of the reflected signal will be affected by the coating thickness. The thicker the coating, the greater the change in the reflected signal; the thinner the coating, the smaller the change in the reflected signal. The thickness of the coating is calculated by measuring and analyzing the changes in these reflected signals. During the tapping test, the stepper motor 19 on the outside of the second lifting plate 15 is electrically started, and the stepper motor 19 drives the spline shaft 20 to rotate. The spline shaft 20 drives the rotating cam 23 sleeved on the outside of the second keyway 31 to rotate. The rotating cam 23 rotates along the outside of the stop sleeve 22, and its convex surface contacts the tapping plate 10 when it rotates to the bottom of the stop sleeve 22. The tapping plate 10 presses the spring support rod 37 downward through the connecting plate 11, so that the tapping plate 10 translates downward along the outside of the positioning bracket 8. At the same time, according to the groove angle of the workpiece, the small motor 25 on the outside of the limit plate 24 can be started, and its motor shaft drives the driving shaft 26 to rotate. The driving shaft 26 drives the guide shaft 27 below to rotate synchronously through the transmission belt 29 attached to the outside. The guide shaft 27 drives the wear-resistant hammer head 28 on the outside to rotate and tilt to the matching angle with the groove and the protruding surface of the workpiece and completes the vertical knocking; at the same time, the rotation of the spline shaft 20 can drive the linear shaft 32 below to rotate through the third locking wheel 34, the linear shaft 32 drives the second locking wheel 33 to rotate, the second locking wheel 33 drives the first locking wheel 13 to rotate, and the two groups of first locking wheels 13 drive their respective threaded rods 12 to rotate in the same direction. Under the transmission of the screw, The positioning bracket 8 threadedly sleeved on the outside of the threaded rod 12 can drive the upper vertical plate 21 to translate along the X-axis direction. The vertical plate 21 pulls the rotating cam 23 through the stop sleeve 22, so that the rotating cam 23 moves synchronously with the positioning bracket 8, thereby performing a single-sided knocking test on workpieces of different lengths; when fixed-point knocking is required, the second locking wheel 33 can be removed; on the other hand, when the workpiece groove is deeper, the top pushing cylinder 17 can be started to push the transverse support frame 16, and the transverse support frame 16 drives the first lifting plate 14 and the second lifting plate 15 to move downward inside the hammer testing machine housing 1, so that the wear-resistant hammer head 28 at the bottom can extend to the outside of the lower press seat 2, thereby increasing the knocking depth.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
