[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] When the hardness tester in the prior art detects the structural adhesive, there is no mechanism for fixing the formed structural adhesive on the hardness tester. Therefore, during the pressurization process, the test position of the formed structural adhesive is likely to move, making the position inaccurate and the data less precise when the staff performs pressure measurement. The following describes a structural adhesive hardness testing device provided by some embodiments of the present utility model in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] In order to prevent the structural adhesive from moving during the detection process, in combination with Figures 1-4As shown in the figure, a hardness testing device for structural adhesives is proposed. By setting the testing mechanism 1 as the main body of the device, the testing mechanism 1 is used to detect the structural adhesive. A fixing mechanism 3 is arranged on the workbench 101, and the fixing mechanism 3 is used to press and fix the structural adhesive. An adjusting mechanism 2 is arranged above the fixing mechanism 3, and the adjusting mechanism 2 is used to position and test different points of the structural adhesive.

[0025] In order to fix and detect the structural adhesive and ensure the test data, a fixing mechanism 3 is proposed. By installing a square frame 304, the top of the workbench 101 is fixedly connected with a fixing plate 301. A groove 303 is opened at the top of the fixing plate 301. Square holes 302 communicating with the groove 303 are opened on both sides of the fixing plate 301. A plurality of round holes a are opened on the square frame 304, and a plurality of insertion rods 305 are slidably connected in the plurality of round holes a. The bottoms of the plurality of insertion rods 305 are fixedly connected with a pressing frame 306. Springs 307 are fixedly connected between the square frame 304 and the pressing frame 306 at the positions of the plurality of insertion rods 305. Connecting plates 308 are fixedly connected to both sides of the square frame 304. A fixing component 309 is arranged at the bottoms of the two connecting plates 308. The fixing component 309 is formed by fixedly connecting a fixing block 3091 to the bottom of one connecting plate 308. A round hole b is opened on one side of the fixing block 3091. A limiting ring 3093 is fixedly connected to the fixing block 3091 in the round hole b. A round rod 3094 is sleeved in the limiting ring 3093. A clamping block 3095 is fixedly connected to one side of the round rod 3094. A gear 3096 is rotatably connected to the bottom of the connecting plate 308 on the side of the fixing plate 301 away from the fixing block 3091. A rack 3097 is fixedly connected to the side of the fixing plate 301 away from the fixing block 3091. A plurality of clamping grooves 3092 are opened on the side of the fixing plate 301 close to the fixing block 3091. By pulling the round rod 3094, the clamping block 3095 is separated from the clamping groove 3092. Move the two connecting plates 308 to move the square frame 304 to one side of the square hole 302. At this time, place the structural adhesive in the groove 303. Move the fixing block 3091 to make the gear 3096 meshingly rotate on the rack 3097, so as to drive the pressing frame 306 to fix the structural adhesive through the square frame 304 and the plurality of springs 307. At this time, press the round rod 3094 to make the clamping block 3095 engage with the clamping groove 3092 at the determined position, so as to press and fix both sides of the detection point of the structural adhesive, avoiding the movement of the test position of the structural adhesive during detection and ensuring the accuracy of the test data.

[0026] The height of the detection head 206 is greater than the maximum distance between the square frame 304 and the pressing frame 306, so that the pressing force applied by the detection head 206 during the detection of the structural adhesive will not be blocked by the square frame 304. A plurality of card slots 3092 are distributed in a linear array, making the fixing position of the square frame 304 more accurate.

[0027] Embodiment 2:

[0028] Based on Embodiment 1, the technical solution proposed in Embodiment 1 is used to solve the problem in the prior art that the test position of the structural adhesive formed during the pressurization process is prone to move, making the position of the staff inaccurate during the pressure measurement and the data not precise enough. However, during the detection of the structural adhesive, the detection position is relatively single, and the staff mostly manually moves the position of the structural frame fighter, making the test position of the structural adhesive inaccurate and the detection effect poor.

[0029] In order to simply adjust the detection points of the structural adhesive, in combination with Figure 1 and Figure 2 and Figure 3 as shown, a regulating mechanism 2 is now proposed. By opening a through slot 201 in the connecting block 106, a small screw 202 is rotatably connected in the through slot 201, a sliding plate 203 is slidably connected in the through slot 201, a through hole communicating with the through slot 201 is opened at the bottom of the connecting block 106, an indicating block 204 is fixedly connected to one side of the sliding plate 203, one end of the small screw 202 penetrates through one side of the connecting block 106 and is fixedly connected with an adjusting wheel 205, the bottom of the sliding plate 203 is fixedly connected with a detection head 206. By rotating the adjusting wheel 205, the small screw 202 rotates, thereby driving the sliding plate 203 to slide in the through slot 201, so that the sliding plate 203 drives the position of the detection head 206 to move. By comparing the position of the indicating block 204 with that of the detection head 206, the position of the detection head 206 can be simply known, so as to detect the hardness of different points of the structural adhesive, improving the detection effect of the device.

[0030] In order to ensure the detection effect of the device on the structural adhesive, a testing mechanism 1 is proposed. By setting a workbench 101, a support rod is fixedly connected to the top of the workbench 101. A fixed platform is fixedly connected to the support rod. A worm gear 103 is rotatably connected inside the fixed platform. A turning handle 102 fixedly connected to one end of the worm gear 103 is installed on one side of the fixed platform. A slide bar a is slidably connected to the top of the fixed platform. A worm 104 is fixedly connected to the bottom end of the slide bar a. A slide bar b is fixedly connected to the bottom end of the worm 104. A pressure gauge 105 is installed at the bottom end of the slide bar b. A connection block 106 is fixedly connected to the bottom of the pressure gauge 105. The slide bar a penetrates through the top of the fixed platform, and the slide bar b penetrates through the bottom of the fixed platform. The position of the support rod is fixed by the workbench 101. By rotating the turning handle 102, the worm gear 103 inside the fixed platform is driven to rotate, so as to mesh with the worm 104, causing the slide bar a and the slide bar b to drive the worm 104 to slide on the fixed platform. The pressure value is displayed by the pressure gauge 105. The position of the detection head 206 is simply adjusted by the connection block 106, so that the device can effectively detect the structural adhesive.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
