Description

Technical Field

[0001] This utility model belongs to the field of electroplating technology for eyeglass frames, and relates to a test device for testing the adhesion of coatings on wet electroplated stainless steel eyeglass frames. Background Technology

[0002] Eyeglasses are simple optical devices made to correct vision or protect the eyes. They consist of frames and lenses, serving as both a tool for eye protection and a cosmetic accessory. Eyeglass frames are primarily made of stainless steel and typically require electroplating. The plating formed by wet electroplating of stainless steel eyeglass frames needs to be tested using a testing device. For example, prior art patent publication number CN213148711U discloses a testing machine for testing the bonding strength of eyeglass frame coatings. This testing machine is used to test the bonding strength of eyeglass frame coatings. The testing machine includes: a machine plate for component mounting, connected to a support base and clamps; clamps for holding the eyeglasses; a pressure rod connected to the support base; and a support base located on the base plate to facilitate the movement of the pressure rod. This invention allows the eyeglass frame to be placed on the clamps, and pressure applied by the pressure rod, thus solving the problem of testing the bonding strength of eyeglass frame coatings. It has a simple structure, is easy to operate, and provides accurate and visualized measurement results.

[0003] This solution addresses the issue of bonding force testing for eyeglass frame coatings by applying pressure to a pressure bar. However, since the pressure is applied manually, it cannot guarantee the movement accuracy of the collar (mainly horizontal movement accuracy) during the pressure application process. This results in uneven contact force during the movement of the collar, affecting the test results. Therefore, we designed a testing device for the bonding force of wet electroplated stainless steel eyeglass frame coatings. Summary of the Invention

[0004] The purpose of this invention is to provide a testing device for the adhesion of coatings on wet electroplated stainless steel eyeglass frames, in order to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: a testing device for the bonding strength of wet electroplated stainless steel metal eyeglass frames, comprising a testing platform plate, a fixture base, and a testing sleeve column. The fixture base is installed on one side of the top of the testing platform plate, with the clamping opening of the fixture base facing upwards. An electric reciprocating cylinder is installed on the side of the top of the testing platform plate. The output shaft of the electric reciprocating cylinder is equipped with a connecting shaft. One end of the connecting shaft is connected to a ball joint. One end of the ball joint is provided with a swing rod. A rotary connecting seat is installed at the tail end of the swing rod. A pad is installed at the bottom end of the rotary connecting seat. The rotary connecting seat is connected to the top of the testing platform plate through the pad. The testing sleeve column is set on the body of the swing rod and corresponds to the clamping opening of the fixture base.

[0006] In the aforementioned testing apparatus for the adhesion of wet electroplated stainless steel eyeglass frames, a flat portion is provided on one side of the top of the fixture base. A sliding mating groove is provided at the top of the flat portion, and a limiting clamp is slidably installed inside the sliding mating groove. The side of the limiting clamp is provided with a clamping arc surface, which fits into the clamping opening of the fixture base. This design facilitates material unloading. When unloading a stainless steel eyeglass frame, the limiting clamp is horizontally adjusted to gradually separate from the clamping opening of the fixture base, making it easy to remove the stainless steel eyeglass frame.

[0007] In the aforementioned testing apparatus for the adhesion of wet electroplated stainless steel eyeglass frames, an L-shaped connecting rod is provided on the other side of the top of the fixture base, and a mounting post is provided at the top of the test sleeve column. A guide ball is provided at one end of the mounting post, and a guide hole is formed in the middle of the guide ball. The L-shaped connecting rod is inserted into and connected to the guide hole. This arrangement aims to further limit the radial oscillation of the test sleeve column, ensuring good motion accuracy.

[0008] In the aforementioned testing apparatus for the adhesion of wet electroplated stainless steel eyeglass frames, a strip groove is provided at the clamping opening of the fixture. This design ensures the secure clamping of the stainless steel eyeglass frame, allowing the frame portion to be engaged within the strip groove, exposing the plating area to be tested.

[0009] In the aforementioned test apparatus for the adhesion of wet electroplated stainless steel eyeglass frames, a threaded inner sleeve is installed on the side of the spherical joint, and a threaded post is provided at the end of the connecting shaft. The threaded post is threadedly connected to the threaded inner sleeve. This arrangement facilitates better connection to the spherical joint, ensuring a strong and secure connection between the spherical joint and the electric reciprocating cylinder, and reducing loosening during operation.

[0010] In the aforementioned testing apparatus for the adhesion of wet electroplated stainless steel eyeglass frames, the outer wall of the coupling part is provided with a coupling seat for connecting the housing of an electric reciprocating cylinder, and the clamp of the coupling seat is connected to the coupling part. This arrangement aims to better ensure the firmness of the connection between the electric reciprocating cylinder and the coupling part, while also facilitating easier removal and installation of the coupling part.

[0011] Compared with existing technologies, the advantages of this utility model's testing device for the bonding force of wet electroplated stainless steel eyeglass frames are as follows: By setting an electric reciprocating cylinder, the output shaft of the electric reciprocating cylinder is connected to a ball joint, which allows the swing rod connected to the ball joint to swing horizontally, ensuring the accuracy of the movement without the need for manual force application. This ensures the accuracy of the movement and the uniformity of the contact force during the reciprocating swing of the test sleeve. By setting an L-shaped connecting rod on the other side of the top of the fixture seat, and setting a mounting post at the top of the test sleeve, with a guide ball at one end of the mounting post and a guide hole in the middle of the guide ball, the L-shaped connecting rod is inserted and connected to the guide hole, further limiting the radial swing of the test sleeve and ensuring good movement accuracy.
