Abstract
Description
Technical Field
[0001] The utility model belongs to the field of electroplating product testing equipment, and particularly relates to a water-based sealant hardness tester. Background Art
[0002] Electroplating is a process that uses the principle of electrolysis to deposit a metal film on the surface of metal or other conductive materials.
[0003] The electroplating process involves the knowledge of electrochemistry. Through electrolysis, a thin layer of metal or alloy is formed on the surface of the target object. This thin layer can provide a variety of functional improvements, such as improving wear resistance, conductivity, reflectivity and corrosion resistance, and is also used to enhance aesthetics.
[0004] After metal parts are processed, such as mechanical parts and automotive parts, treating their surfaces with a water-based sealant can prevent rust during storage and transportation. For example, applying a water-based sealant to the surface of some small metal parts in a car engine can effectively extend their service life.
[0005] Existing methods for testing the hardness of water-based sealants primarily involve rubbing pencils of varying hardness levels across the coating surface at a specific angle and pressure. The hardness is determined by whether the coating is broken. However, this method involves numerous variables, resulting in inaccurate test results and low efficiency. Utility Model Content
[0006] In order to solve the problems and shortcomings of the existing technology, the purpose of the utility model is to provide a water-based sealant hardness tester, including a base, a lifting seat, a lifting motor, a rotating motor, an upper chuck and a lower chuck. The lifting motor is arranged at the upper end of the lifting seat, the base and the lifting seat are connected by a connecting column, the main shaft of the lifting motor is connected to the upper chuck, the rotating motor is fixedly installed on the base, and the rotating shaft of the rotating motor is connected to the lower chuck.
[0007] Furthermore, the surface of the lower chuck is provided with a plurality of grooves evenly distributed in a circumferential array for placing test samples.
[0008] Furthermore, the groove includes a rectangular groove and a circular groove, and the circular groove is arranged in the middle of the rectangular groove.
[0009] Furthermore, a plurality of slots are provided at the bottom of the upper chuck, and the distance between each slot and the center of the upper chuck is different.
[0010] Furthermore, a hardness testing needle is installed in the slot, and the hardness of the needle tip of each hardness testing needle is different.
[0011] Furthermore, the hardness of the needle tip of the hardness test needle ranges from 6B to 9H.
[0012] Furthermore, an upper transparent protective cover is provided on the edge of the upper chuck, and a lower protective cover is provided on the base. The inner diameter of the upper transparent protective cover is greater than the outer diameter of the lower protective cover.
[0013] Furthermore, each groove edge is provided with a marking mark serving as an identification.
[0014] The utility model is beneficial in that:
[0015] 1. Insert the hardness test needle into the slot of the upper chuck. As the lifting motor drives, it can ensure that the downward pressure of each hardness test needle is the same, the inclination angle of the needle and the test sample is the same, and the sliding speed of the needle on the test sample surface is the same. Each test sample can be tested under the same variables, and the test results are more reliable and accurate.
[0016] 2. The lower chuck features multiple recesses for test samples. Samples can be plated parts treated with the same water-based sealant for horizontal comparison testing. Alternatively, plated parts treated with different water-based sealants can be used for vertical comparison testing. This allows for multiple test results to achieve different testing objectives.

DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0025] A water-based sealant hardness tester, including base, lifting seat, lifting motor, rotating motor, upper chuck and lower chuck, lifting motor is arranged on the upper end of lifting seat, base and lifting seat are connected through connecting column, the main shaft of lifting motor is connected with upper chuck, rotating motor is fixedly installed on the base, the rotating shaft of rotating motor is connected with lower chuck. The surface of the lower chuck is provided with a plurality of circumferential array distributed grooves for placing test samples. The grooves are rectangular grooves and circular grooves, and the circular grooves are arranged in the middle of the rectangular grooves. The bottom of the upper chuck is provided with a plurality of insertion slots, and the distance from each insertion slot to the center of the upper chuck is different. Hardness testing needles are assembled in the insertion slots, and the needle hardness of each hardness testing needle is different. The needle hardness of the hardness testing needle ranges from 6B to 9H. The edge of the upper chuck is also provided with an upper transparent protective cover, and the lower base is provided with a lower protective cover. The inner diameter of the upper transparent protective cover is greater than the outer diameter of the lower protective cover. Each groove edge is provided with a mark for identification.
[0026] The actual use method is as follows:
[0027] Firstly, the upper chuck is moved upward by the lifting motor to leave enough operating space between the upper chuck and the lower chuck, and then the electroplated sample to be tested is placed in the groove of the lower chuck. The electroplated sample adopts certain size specifications, mainly rectangular and circular. The rectangular electroplated sample is placed in the rectangular groove, and the circular electroplated sample is placed in the circular groove.
[0028] Then, install the hardness testing needle, select several hardness testing needles with needle hardness ranging from 6B to 9H according to the actual needs of the test, and insert and fix them in the insertion slots of the upper chuck. The needle angle of the hardness testing needle is 45 degrees by default, and can also be adjusted according to actual needs.
[0029] After the hardness testing needle is assembled, the lifting motor is controlled to move the upper chuck downward by a certain distance, so that the hardness testing needle can slide on the electroplated sample. Since the distance from each hardness testing needle to the center of the upper chuck is different, when the hardness testing needle slides on the electroplated sample, it can quickly correspond the scratch to the corresponding hardness testing needle.
[0030] During testing, the rotating motor is started, the rotating motor drives the lower chuck to rotate, and the hardness testing needle starts to slide on the electroplated sample.
[0031] An upper transparent protective cover is provided on the outside of the upper chuck, and a lower protective cover is provided on the outside of the lower chuck. During operation, the upper transparent protective cover and the lower protective cover are closed to protect the operator.
[0032] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
