Description

Technical Field

[0001] This utility model relates to the field of testing technology for insulated containers, and in particular to a temperature measuring clamping mechanism. Background Technology

[0002] Insulated containers generally refer to containers that have the ability to keep the temperature of liquids and can hold them, such as insulated cups. The body of an insulated cup is usually made of stainless steel to form a vacuum layer. The vacuum insulation layer can slow down the heat dissipation of liquids such as water inside, so as to achieve the purpose of keeping the temperature.

[0003] During the production of thermos cups, it is necessary to conduct heat insulation tests on the finished products. Usually, a clamping mechanism is used to clamp the thermos cup for temperature measurement. However, the existing clamping mechanism is usually designed for cylindrical thermos cups with a fixed outer diameter, and it is difficult to apply to thermos cups with variable diameters, such as frustum-shaped thermos cups, which can easily lead to problems such as the cup falling off or tilting.

[0024] The purpose of this invention is to provide a temperature measuring clamping mechanism to solve the problems existing in the prior art and improve its applicability.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] This embodiment provides a temperature measuring clamping mechanism; please refer to [link / reference]. Figures 1-3The device includes a frame 1, a clamping module 2, a drive module 4, and a temperature measuring component. The clamping module 2 includes a connecting frame 21 and at least two clamping petals 22, each of which can be flipped relative to the connecting frame 21 to clamp onto the surface of the device under test 3. The drive module 4 is mounted on the frame 1 and is connected to the connecting frame 21. The drive module 4 can drive the connecting frame 21 to move relative to the frame 1 so that the clamping petals 22 move closer or further away from each other. The temperature measuring component is mounted on the frame 1 or the clamping module 2 and is used to measure the temperature of the device under test 3.

[0028] Under the overall support of the frame 1, the clamping petals 22 of the clamping module 2 clamp the device 3 to be tested. Since the clamping petals 22 can rotate relative to the connecting frame 21, Figure 3 In the process, the clamping petals 22 can be flipped up and down. When clamping the frustum-shaped device under test 3, the clamping petals 22 can adaptively flip to fully fit the surface of the device under test 3 for clamping. This can meet the stable clamping of devices under test 3 with equal outer diameter, such as cylinders, and with varying outer diameter, such as frustum-shaped devices, thus improving applicability. The driving module 4 can drive the clamping petals 22 to move closer or further apart to achieve clamping or detachment of the device under test 3. The temperature measuring component can measure the temperature of the device under test 3 during the clamping process of the clamping module 2.

[0029] In the optional scheme of this embodiment, more preferably, each clamping petal 22 is provided with an elastic element 5 on the side facing the device under test 3. The elastic element 5 can undergo elastic deformation and adhere to the surface of the device under test 3 when the clamping petal 22 clamps the device under test 3.

[0030] Among them, by setting an elastic element 5 on the clamping petal 22, adaptive deformation occurs during the clamping process to fully fit the device under test 3, thereby increasing the contact area with the device under test 3, and thus increasing the friction and improving the clamping stability.

[0031] In the optional embodiments of this example, more preferably, the elastic element 5 is configured as an elastic band.

[0032] The elastic band increases the contact area with the device under test 3. Furthermore, the elastic element 5 is an elastic friction element, such as rubber, which further improves the clamping stability by utilizing the frictional properties of the material itself. The two ends of the elastic band can be fixedly connected to the clamping flap 22 by screws.

[0033] In the optional scheme of this embodiment, more preferably, the temperature measuring component is disposed on an elastic member 5 for adhering to the side of the device under test 3, and the temperature measuring component can measure the temperature of the surface of the device under test 3 when the elastic member 5 is clamped to the surface of the device under test 3.

[0034] By placing the temperature measuring component on the side of the elastic element 5 to adhere to the side of the device under test 3, the device under test 3 can be directly contacted for temperature measurement when it is clamped, thus improving the accuracy of the measurement.

[0035] In the optional scheme of this embodiment, more preferably, each elastic member 5 is provided with at least one temperature measuring component on the side of the device to be tested 3 for attaching to it.

[0036] By setting temperature measuring components on each elastic element 5, different parts of the device under test 3 can be measured, which helps to improve the accuracy of the measurement. Furthermore, multiple temperature measuring components are set on each elastic element 5 to further improve the accuracy of the measurement data.

[0037] In the optional embodiments of this example, it is more preferable that the temperature measuring component is set as a patch sensor.

[0038] Among them, the patch sensor is easy to attach to the surface of the elastic element 5 to realize the measurement of the device under test 3; specifically, it can be set as a patch thermocouple, which is directly attached to the surface of the elastic element 5, or a groove is set on the surface of the elastic element 5 so that the patch thermocouple is embedded in the groove.

[0039] In addition, the temperature measuring component can also be installed on the frame 1. Specifically, the temperature measuring component can be set as an infrared thermometer.

[0040] In the optional scheme of this embodiment, more preferably, the clamping petal 22 is provided with a clamping groove 23 on the side facing the device under test 3, and the elastic member 5 is provided in the clamping groove 23.

[0041] The clamping groove 23 is provided so that the elastic element 5 can be placed in the clamping groove 23. When it comes into contact with the device under test 3, the elastic element 5 has a deformation space.

[0042] In the optional scheme of this embodiment, it is more preferred that the clamping groove 23 is set as a V-shaped groove, which can meet the clamping of devices 3 under test with different diameters.

[0043] In the optional embodiment, more preferably, the connecting frame 21 includes a first clamping arm 211 and a second clamping arm 212, and the number of clamping petals 22 is set to two. A clamping petal 22 is rotatably connected to the end of the first clamping arm 211 and the end of the second clamping arm 212 respectively. The first clamping arm 211 and the second clamping arm 212 are slidably connected to the frame 1. The driving module 4 is driven to the first clamping arm 211 and the second clamping arm 212. The driving module 4 can drive the first clamping arm 211 and the second clamping arm 212 to slide relative to the frame 1, so as to drive the corresponding clamping petals 22 to move closer or further away from each other.

[0044] The first clamping arm 211 and the second clamping arm 212 are designed to facilitate the separate driving of the two clamping segments 22. Furthermore, a slide rail is provided at the bottom of the frame 1, and a sliding groove is provided at the top of the first clamping arm 211 and the second clamping arm 212; alternatively, a sliding groove is provided at the bottom of the frame 1, and a slide rail is provided at the top of the first clamping arm 211 and the second clamping arm 212. The slide rail and the sliding groove cooperate to achieve a stable sliding connection. The length direction of the slide rail and the sliding groove is parallel to the direction in which the clamping segments 22 approach or move away from each other. Further, the sliding groove is designed as an anti-drop structure, such as a C-shape or a T-shape, and correspondingly, the slide rail is designed as a C-shape or a T-shape to prevent the sliding groove and the slide rail from falling off, thereby improving the stability of the sliding fit.

[0045] In a preferred embodiment, the drive module 4 includes a telescopic drive component 41, a drive frame 42, a first rack 43, a transmission gear 44, a transmission frame 45, and a second rack 46. The first rack 43 and the second rack 46 are arranged in parallel. The transmission gear 44 is disposed between the first rack 43 and the second rack 46 and is rotatably connected to the frame 1. The transmission gear 44 is also meshed with both the first rack 43 and the second rack 46. The first rack 43 is fixedly connected to the first clamping arm 211 through a transmission frame 45, and the second rack 46 is fixedly connected to the second clamping arm 212 through another transmission frame 45. The telescopic drive component 41 is disposed on the frame 1, and the drive end of the telescopic drive component 41 is fixedly connected to the first clamping arm 211 through the drive frame 42. The telescopic drive component 41 can drive the first clamping arm 211 and the first rack 43 to move synchronously in a straight line through the drive frame 42. The first rack 43 can drive the second rack 46 and the second clamping arm 212 to move synchronously in a straight line through the transmission gear 44.

[0046] The telescopic drive component 41 can be configured as a telescopic electric cylinder or a telescopic pneumatic cylinder, and is fixedly connected to the frame 1 via a mounting base. The drive end of the telescopic drive component 41 is fixedly connected to the drive frame 42 via bolts. The telescopic drive component 41 reciprocates, causing the drive frame 42 to move synchronously. The drive frame 42 is bolted to the first clamping arm 211. The first clamping arm 211 and the first rack 43 are connected via a transmission frame 45 and fixed with bolts. The movement of the drive frame 42 causes the first clamping arm 211 and the first rack 43 to slide synchronously relative to the frame 1. At the same time, the first rack 43 drives... The transmission gear 44 rotates and is rotatably connected to the frame 1 via a rotating shaft. The transmission of the transmission gear 44 can drive the second rack 46 to move linearly in the opposite direction to the first rack 43. The second rack 46 and the second clamping arm 212 are connected by a transmission frame 45 and fixed by bolts. The second rack 46 can drive the second clamping arm 212 to slide synchronously relative to the frame 1, thus realizing the mutual approach or distance between the two clamping petals 22. The synchronous movement of the two clamping petals 22 can be realized by a telescopic drive member 41, which simplifies the structure and reduces costs.

[0047] Furthermore, it should be noted that the driving method of the first clamping arm 211 and the second clamping arm 212 is not limited to the structure of the driving module 4 described above. As long as the first clamping arm 211 and the second clamping arm 212 can be driven closer or further away, the first clamping arm 211 and the second clamping arm 212 can also be driven separately by a driving component such as an electric telescopic cylinder.

[0048] In the optional embodiments of this example, it is more preferred that the ends of the first clamping arm 211 and the second clamping arm 212 are provided with limiting portions 213, which can limit the flipping of the clamping petal 22.

[0049] The ends of the first clamping arm 211 and the second clamping arm 212 are... Figure 3 The lower end of each of the shown parts is provided with a movable groove 214. A connecting block 215 is fixedly provided on the back of the clamping petal 22. The connecting block 215 is rotatably connected to the two side plates of the movable groove 214 through a connecting shaft 216. The first clamping arm 211 and the second clamping arm 212 are connected to the lower end of the corresponding movable groove 214 as a limiting part 213. In the initial state, there is a gap between the upper side of the connecting block 215 and the limiting part 213. When the clamping petal 22 is flipped up and down to the limit position, the connecting block 215 can abut against the limiting part 213 to limit it. By adjusting the size of the gap between the upper side of the connecting block 215 and the limiting part 213 in the initial state, the range of the flipping limit angle can be adjusted.

[0050] In addition, the limiting part 213 can also be configured with other structures, such as setting a limiting rod at the upper and lower flipping limit position of the clamping petal 22. When the clamping petal 22 flips to the limit position, it abuts against the limiting rod to limit the position. It should be noted that in the actual application of the temperature measuring clamping mechanism provided in this embodiment, for the clamping of the frustum-shaped device under test 3, the small end of the device under test 3 is usually facing upward. In this way, the clamping petal 22 only needs to be flipped downward to adapt to the surface shape of the device under test 3. Therefore, it is only necessary to limit the downward flipping of the clamping petal 22. For example, a limiting plate is set on the side of the connecting block 215 away from the clamping petal 22. When the clamping petal 22 flips downward to the limit position, the limiting plate abuts against the corresponding first clamping arm 211 and second clamping arm 212 to limit the position.

[0051] Example 2

[0052] This embodiment provides a temperature measuring clamping mechanism, which differs from the temperature measuring clamping mechanism provided in Embodiment 1 in that:

[0053] The clamping module 2 includes multiple clamping petals 22, more than two in number. The driving module 4 is configured as multiple, evenly distributed along the circumference. Each clamping petal 22 is connected to a driving module 4 through a clamping arm. The driving module 4 is configured as a telescopic motor, which drives each clamping petal 22 individually to achieve circumferential clamping of the device under test 3.

[0054] The other structures of the temperature measuring clamping mechanism provided in this embodiment are the same as those in Embodiment 1, and will not be described in detail here. The temperature measuring clamping mechanism provided in this embodiment is supported by the frame 1 as a whole. Multiple clamping petals 22 clamp the device under test 3 under the drive of multiple telescopic motors. Since the clamping petals 22 can rotate relative to the corresponding clamping arms, when clamping the frustum-shaped device under test 3, the clamping petals 22 can rotate to fully fit themselves against the surface of the device under test 3 for clamping. This can meet the stable clamping of devices under test 3 with equal outer diameter, such as cylinders, and with varying outer diameter, such as frustum-shaped devices, thus improving applicability. The driving module 4 can drive the clamping petals 22 to move closer or further away from each other to achieve clamping or releasing of the device under test 3.

[0055] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
