Description

Technical Field

[0001] The utility model belongs to the technical field of glue hardness detection, and more specifically, it particularly relates to a hardness tester for glue hardness detection. Background Art

[0002] The hardness of glue depends on its formula and physical properties after curing. According to actual usage requirements, different types of glue can be selected for use, and different types of glue also have differences in hardness and performance. For example, the hardness of UV glue (ultraviolet light curing type) can be adjusted according to needs to adapt to different bonding requirements, while epoxy resin, anaerobic glue, hot melt glue, pressure-sensitive glue, etc. also have their own characteristics and application fields. Among them, epoxy-type ABS glue usually has a relatively high hardness, while polyurethane-type ABS glue may have better resilience and bending resistance.

[0003] When developing and producing glue, it is necessary to detect and test its hardness after curing. Currently, the indentation hardness testing method is often used to detect the hardness of glue. Specifically, a steel ball is pressed into the surface of the cured glue under a certain load, and the indentation diameter or indentation depth is measured to evaluate the hardness of the glue.

[0004] For the existing glue hardness testing, there is no detection tool that combines detection and indication. When testing, the pressing of the steel ball and the measurement of the pressing depth are realized through two separate steps, which are cumbersome. Moreover, the indentation of the steel ball is generally relatively shallow, and general measuring instruments cannot accurately measure the pressing depth of the steel ball, resulting in low accuracy and poor practicality of the detection results.

[0023] The following further describes the implementation mode of the present utility model in detail in conjunction with the drawings and embodiments.

[0024] As shown in Attach Figure 1 to Attach Figure 6 shown:

[0025] Embodiment 1: The present utility model provides a glue hardness tester, including a test component 1. The test component 1 includes a placing seat 101, a force application rod 102 and a detection steel ball 103. The force application rod 102 is inserted into the inside of the placing seat 101, and the detection steel ball 103 is fixedly installed at the bottom of the force application rod 102; an indication component 2, the indication component 2 includes a linkage shaft 201 and an amplification shaft 202. The linkage shaft 201 is rotatably connected to the inside of the placing seat 101, and the amplification shaft 202 is rotatably connected to the inside of the placing seat 101.

[0026] In the embodiment of the present disclosure, the placing seat 101 is designed as a frustum-shaped seat body, and the radius of the top surface of the placing seat 101 is smaller than the radius of the ground surface. During use, when it is necessary to detect the hardness of the cured glue, only the placing seat 101 needs to be placed on the glue surface to complete the preparation action. The frustum-shaped design of the placing seat 101 can well distribute the self-weight of the test component 1 and the indication component 2 to the glue surface, and the placing seat 101 will not penetrate into the inside of the glue after being placed, ensuring the accuracy of the detection result.

[0027] In the embodiment of the present disclosure, a track block 1021 is provided on the side surface of the force application rod 102, and a track rod 1011 is provided inside the placing seat 101. The track block 1021 is inserted into the inside of the placing seat 101, and the track rod 1011 is inserted into the inside of the track block 1021. This design can limit the movement track of the force application rod 102 inside the placing seat 101, so that the force application rod 102 will not be skewed or distorted during movement, resulting in the device getting stuck and failing, and the use is stable.

[0028] In the embodiment of the present disclosure, an indicating scale 1012 is provided on the top of the placing seat 101, and a scale pointer 2022 is provided on the outside of the magnifying shaft 202. When the lowest end of the detection steel ball 103 is flush with the bottom plane of the placing seat 101, the scale pointer 2022 indicates the zero position of the indicating scale 1012. During use, when the placing seat 101 is placed on the surface of the cured glue, at this time, the lowest end of the detection steel ball 103 is flush with the bottom plane of the placing seat 101, and the scale pointer 2022 is at the zero position of the indicating scale 1012. Then, after applying a load to the force application rod 102, the detection steel ball 103 can be pressed into the interior of the cured glue to complete the detection action. A spiral linkage groove 1022 is provided on the outside of the force application rod 102, and a linkage protrusion 2011 is provided inside the linkage shaft 201. The linkage protrusion 2011 is inserted into the linkage groove 1022. While the detection steel ball 103 is being pressed into the interior of the cured glue, the force application rod 102 will move downward synchronously. When the force application rod 102 moves downward, the linkage groove 1022 can drive the linkage shaft 201 to rotate through the linkage protrusion 2011. A large gear 2012 is provided on the outside of the linkage shaft 201, and a small gear 2021 is provided on the outside of the magnifying shaft 202. The teeth of the large gear 2012 and the small gear 2021 are engaged for transmission. When the linkage shaft 201 rotates, the large gear 2012 can drive the magnifying shaft 202 to rotate through the small gear 2021. By adopting the transmission mode of the large gear 2012 driving the small gear 2021, the magnifying shaft 202 can magnify the rotation angle of the linkage shaft 201. Thus, the indicating accuracy of the scale pointer 2022 will be higher, which is convenient for the staff to observe and record. It can simultaneously realize the functions of glue hardness detection and indication, simplify the operation process, and improve the detection efficiency.

[0029] Specific usage method and function of this embodiment:

[0030] In the present utility model, when it is necessary to detect the hardness of the cured glue, the preparation action can be completed by simply placing the placement seat 101 on the surface of the glue. The placement seat 101 is designed in a frustum shape, which can well distribute the self-weights of the test assembly 1 and the indicating assembly 2 to the surface of the glue. After being placed, the placement seat 101 will not penetrate into the interior of the glue, ensuring the accuracy of the detection result. When the placement seat 101 is placed on the surface of the cured glue, at this time, the lowest end of the detection steel ball 103 is flush with the bottom plane of the placement seat 101, and the scale pointer 2022 is at the zero position of the indicating scale 1012. Then, after applying a load to the force application rod 102, the detection steel ball 103 can be pressed into the interior of the cured glue to complete the detection action. While the detection steel ball 103 is being pressed into the interior of the cured glue, the force application rod 102 will move downward synchronously. When the force application rod 102 moves downward, the linkage groove 1022 can drive the linkage shaft 201 to rotate through the linkage protrusion 2011. When the linkage shaft 201 rotates, the large gear 2012 can drive the magnification shaft 202 to rotate through the small gear 2021. By adopting the transmission method of the large gear 2012 driving the small gear 2021, the magnification shaft 202 can magnify the rotation angle of the linkage shaft 201, so that the indicating accuracy of the scale pointer 2022 will be higher, facilitating the observation and recording by the staff.
