Description

Technical Field

[0001] The utility model relates to the technical field of hardness detection of thermal insulation shells, and specifically relates to a hardness detection device for thermal insulation shells. Background Technique

[0002] A thermal insulation shell usually refers to a protective layer or shell used to wrap or cover the outside of an object that needs thermal insulation, so as to reduce heat loss or intrusion and maintain the stability of the internal temperature. Thermal insulation shells can be applied in multiple fields, including but not limited to buildings, pipeline insulation, refrigerators and refrigeration equipment, and specific transportation containers (such as insulated boxes for cold chain transportation), etc. During the production of thermal insulation shells, a hardness detection device is required to detect the performance of the thermal insulation shells.

[0003] The clamping effect of some thermal insulation shell hardness detection devices on the thermal insulation shell during the test is not ideal enough. If the clamping is unstable, the thermal insulation shell may undergo slight movement or deformation during the hardness test, which directly affects the accuracy of hardness measurement. Especially for softer or easily deformable thermal insulation materials, unstable clamping may cause displacement of the test point, resulting in a higher or lower hardness value. Content of the Utility Model

If the clamping is unstable, the thermal insulation shell may undergo slight movement or deformation during the hardness test, which directly affects the accuracy of hardness measurement. Especially for softer or easily deformable thermal insulation materials, unstable clamping may cause displacement of the test point, resulting in a higher or lower hardness value.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A hardness detection device for thermal insulation shells, including a workbench and a clamping mechanism arranged at the center of its top, and a hardness detection mechanism is connected to the rear side of the top of the workbench:

[0006] The clamping mechanism includes a sliding seat fixedly arranged at the center of the top of the workbench. The left and right sides of the top of the sliding seat are respectively slidably connected with a first slider and a second slider. Clamping plates are connected to the opposite sides of the first slider and the second slider, and a plurality of first springs are fixedly connected between the clamping plates and the first slider and the second slider.

[0007] Preferably, as a hardness detection device for thermal insulation shells of the utility model, a positioning block is arranged on one side of the first slider, a connecting rod is fixedly connected between the first slider and the positioning block, and the connecting rod is slidably connected with the second slider.

[0009] Preferably, as a heat preservation shell hardness detection device of the utility model, a cam is slidably connected between the second slider and the positioning block. A rotating shaft is fixedly connected to the inner wall of the cam, and a first motor is fixedly connected to the bottom of the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model is fixed at the center of the top of the workbench through a sliding seat, providing a stable sliding foundation for the first slider and the second slider.

Specific implementation mode

[0023] Please refer to Figures 1-5 , a hardness detection device for a heat preservation shell, including a workbench 1 and a clamping mechanism 2 arranged at the center of its top. A hardness detection mechanism 3 is connected to the rear side of the top of the workbench 1:

[0024] Furthermore, the clamping mechanism 2 includes a sliding seat 201 fixedly arranged at the center of the top of the workbench 1. A first slider 202 and a second slider 203 are respectively slidably connected to the left and right sides of the top of the sliding seat 201. Clamping plates 204 are connected to the opposite sides of the first slider 202 and the second slider 203. A plurality of first springs 205 are fixedly connected between the clamping plates 204 and the first slider 202 and the second slider 203.

[0025] The sliding seat 201 is fixed at the center of the top of the workbench 1, providing a stable sliding base for the first slider 202 and the second slider 203. This design allows the clamping mechanism 2 to have a certain adjustment range in the horizontal direction, which helps to adapt to heat preservation shell samples of different sizes and improves versatility. The first slider 202 and the second slider 203 are respectively located on both sides of the sliding seat 201, and the heat preservation shell is clamped through the clamping plates 204. Such a bilateral symmetric clamping design can fix the sample more evenly and stably, reduce the offset or distortion during the test, and improve the accuracy and repeatability of the test. Each clamping plate 204 is connected to the first slider 202 and the second slider 203 through a plurality of first springs 205. The function of the first springs 205 is to provide an appropriate clamping pressure. The first springs 205 can be adjusted moderately according to the size and material hardness of the heat preservation shell, ensuring both sufficient clamping force to prevent the sample from slipping and avoiding excessive pressure from damaging the sample, reflecting flexibility and protection. This device aims to solve the problems of unstable clamping and sample damage that may occur during the hardness detection of the heat preservation shell through mechanisms such as sliding adjustment, symmetric clamping, and first spring 205 loading, thereby improving the accuracy, efficiency of the test, and the safety of the sample.

[0026] Furthermore, a positioning block 208 is arranged on one side of the first slider 202. A connecting rod 206 is fixedly connected between the first slider 202 and the positioning block 208. The connecting rod 206 is slidably connected to the second slider 203.

[0027] As a bridge between the first slider 202 and the second slider 203, the connecting rod 206 not only realizes the synchronous sliding of the two, but also enhances the stability of the entire clamping mechanism 2 through its fixed connection with the first slider 202 and the positioning block 208. This design enables the second slider 203 to make corresponding adjustments when the position of the first slider 202 is adjusted, maintaining the balance of the clamping forces on both sides.

[0028] Furthermore, a second spring 207 is movably sleeved on the surface of the connecting rod 206 and is fixedly connected between the first slider 202 and the second slider 203.

[0029] The second spring 207 is sleeved on the surface of the connecting rod 206 and is fixedly connected to the first slider 202 and the second slider 203. Such a design further enhances the flexibility and self - adaptability of the clamping. In addition to providing an additional clamping force, the second spring 207 can also absorb the stress caused by the difference in sample size or minor changes during the operation to a certain extent, reducing damage to the sample while maintaining a stable clamping state.

[0030] Furthermore, a cam 209 is slidably connected between the second slider 203 and the positioning block 208. A rotating shaft 210 is fixedly connected to the inner wall of the cam 209, and a first motor 211 is fixedly connected to the bottom of the rotating shaft 210. The first motor 211 is fixedly arranged on the top of the workbench 1.

[0031] The first motor 211 is fixed on the top of the workbench 1 and is connected to the bottom of the rotating shaft 210. Its introduction enables the relative movement between the above - mentioned cam 209 and the second slider 203 to be automatically controlled. The operator can precisely adjust the clamping width through the control of the first motor 211, which not only simplifies the manual adjustment process, but also improves the adjustment accuracy and speed, reducing human error.

[0032] Furthermore, the hardness detection mechanism 3 includes an L - shaped plate 301 fixedly arranged at the rear side of the top of the workbench 1. An installation seat 306 is arranged below the interior of the L - shaped plate 301, and a hardness detector 307 is fixedly connected to the bottom of the installation seat 306.

[0033] As a support structure, the L - shaped plate 301 provides a stable installation platform for the hardness detector 307 through the installation seat 306 arranged below its interior. This layout not only saves space but also ensures the stability and accuracy of the hardness detector 307 during the test.

[0034] Furthermore, a sliding rod 308 is fixedly connected to the top of the installation seat 306. The top of the sliding rod 308 extends above the L - shaped plate 301 and is slidably connected to it. A third spring 309 is movably sleeved on the surface of the sliding rod 308 and is fixedly connected between the L - shaped plate 301 and the sliding rod 308.

[0035] The sliding connection between the sliding rod 308 and the L-shaped plate 301, combined with the design of the third spring 309, provides the hardness detector 307 with flexibility and buffering effect for up and down movement. This not only helps to adapt to samples of different heights, but also ensures the uniformity and control of the contact pressure during the detection process, reducing the influence that may be brought by misoperation.

[0036] Further, a limiting groove 302 is formed on one side of the inner wall of the L-shaped plate 301. A threaded rod 303 is rotatably connected inside the limiting groove 302. The top of the threaded rod 303 extends above the L-shaped plate 301 and is fixedly connected to a second motor 304. The second motor 304 is fixedly arranged on the top of the L-shaped plate 301.

[0037] The combination of the threaded rod 303 and the second motor 304 forms a precise vertical position adjustment system through the sliding connection between the threaded block 305 and the limiting groove 302. The driving of the second motor 304 enables the threaded block 305 to move up and down, driving the mounting seat 306 and the hardness detector 307 to achieve precise height adjustment. This design greatly improves the automation level and efficiency of the detection, and at the same time ensures the height consistency of each test.

[0038] Further, the surface of the threaded rod 303 is threadedly connected with a threaded block 305. The threaded block 305 is slidably connected with the limiting groove 302. A fixed connection is provided between one side of the threaded block 305 and one side of the mounting seat 306.

[0039] The provided hardness detection mechanism 3 can automatically adjust the height of the hardness detector 307 according to the specific position and size of the heat preservation shell, and at the same time ensure that the force applied to the heat preservation shell during the whole test process is stable and adjustable.

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
