[0031] like Figure 1 As shown in the figure, this embodiment discloses a clamping device, which includes a base plate 1 and a clamping assembly 2.
[0032] like Figure 2 As shown, the base plate 1 is, for example, a rectangular plate structure, and multiple placement areas S1 are provided on the base plate 1. The multiple placement areas S1 are arranged along the first direction X1, so as to... Figure 1As shown in the view, it can be understood that each placement region S1 is a rectangular region, and a plurality of placement regions S1 are arranged along the first direction X1, and each placement region S1 extends along the second direction X2. A plurality of placement slots 11 are arranged in each placement region S1, and the plurality of placement slots 11 are arranged along the second direction X2 and extend along the first direction X1, so that Figure 2 As shown in the view, each placement slot 11 is, for example, a rectangular slot, and the slot bodies of adjacent two placement slots 11 can be communicatively arranged or can be arranged at intervals. It can be understood that the shapes of the placement slots 11 in the same placement region S1 can be the same, and the shapes of the placement slots 11 in different placement regions S1 can be different, so that one clamping device can clamp and detect products of different shapes. The to-be-detected product extending along the first direction X1 is limited in the placement slot 11. It can be understood that a plurality of to-be-detected products can be placed in a single placement region S1, and at this time, the plurality of to-be-detected products are arranged along the second direction X2, and the detection device can simultaneously detect a plurality of products, thereby improving the detection efficiency. The first direction X1 and the second direction X2 are arranged at an angle, for example, 90°.
[0033] In combination with Figure 1 , Figure 2 As shown in the view, the number of the pressing assemblies 2 is a plurality, and the plurality of pressing assemblies 2 are arranged on the bottom plate 1 along the first direction X1 and extend along the second direction X2. The plurality of pressing assemblies 2 are arranged in one-to-one correspondence with the plurality of placement regions S1. In other words, each placement region S1 is provided with one pressing assembly 2. Since each pressing assembly 2 extends along the second direction X2, and the plurality of placement slots 11 in each placement region S1 are arranged along the second direction X2, the pressing assembly 2 in each placement region S1 can simultaneously contact the plurality of placement slots 11 in the placement region S1, thereby enabling one pressing assembly 2 to simultaneously press a plurality of to-be-detected products in a plurality of placement slots 11.
[0034] In combination with Figure 1 , Figure 3 As shown in the view, the pressing assembly 2 includes a pressing plate 21, a pressing member 23 arranged on the pressing plate 21, and a locking member 22 arranged on the pressing plate 21. The pressing plate 21 is, for example, a rectangular plate structure, and its extension direction is the same as the extension direction of the pressing assembly 2, that is, extending along the second direction X2. The pressing plate 21 is provided with a detection opening 211, and the shape of the detection opening 211 is, for example, the same as the shape of the pressing plate 21, that is, the detection opening 211 is also rectangular, and the extension direction of the detection opening 211 is the same as the arrangement direction of the plurality of placement slots 11, that is, the detection opening 211 extends along the second direction X2. The pressing member 23 can be elastically deformed, and the pressing member 23 is, for example, a spring or a rubber column or other structure capable of elastically deforming. The locking member 22 is used to lock the pressing plate 21 and the bottom plate 1.
[0035] As shown in Figure 1 When the pressing assembly 2 and the bottom plate 1 are locked, the pressing piece 23 is in contact with the product to be detected, and the pressing piece 23 is elastically deformed under the extrusion force, so that the product to be detected is clamped between the pressing piece 23 and the placing groove 11, and part of the product to be detected is exposed to the outside through the detection port 211.
[0036] Therefore, in the clamping device, the product to be detected is limited in the placing groove 11 on the bottom plate 1, and the product to be detected is limited by the groove body of the placing groove 11; the pressing assembly 2 is arranged in one-to-one correspondence with the placing area S1 on the bottom plate 1, and the structure of the pressing assembly 2 is arranged to include the pressing plate 21 provided with the detection port 211, the locking piece 22 arranged on the pressing plate 21 and used for locking the pressing plate 21 and the bottom plate 1, and the pressing piece 23 arranged on the pressing plate 21 and capable of being elastically deformed. In this way, when the pressing assembly 2 is in contact with the product to be detected limited in the placing groove 11, the product to be detected can be clamped between the pressing piece 23 and the placing groove 11, the product to be detected is limited by the groove body of the placing groove 11, the product to be detected is pressed and fixed by the pressing assembly 2, and part of the product to be detected can be exposed to the outside through the detection port 211, so that the product to be detected can be detected. In addition, in the process of pressing the product to be detected, the pressing piece 23 can be elastically deformed, and when the pressing assembly 2 presses the product to be detected, the product to be detected can be subjected to the downward pressure applied by the pressing plate 21 and the elastic force released by the elastic deformation of the pressing piece 23. Under the action of the elastic force, the pressing piece 23 can always be in contact with the product to be detected, avoiding that the product to be detected is abraded due to the close fit between the product to be detected, the placing groove 11 and the pressing plate 21, and avoiding that the product to be detected is slightly shaken due to the loose fit between the product to be detected, the placing groove 11 and the pressing plate 21, which affects the detection result. The product to be detected is not abraded and is stably installed, so that the detection image can be correctly generated.
[0037] In some embodiments, as Figure 4As shown, the pressing member 23 comprises a pressing member body 231 and a pressing portion 232. The pressing member body 231 is, for example, a cylindrical structure or a cubic structure, and the pressing portion 232 is made of an elastic material and can be elastically deformed. The pressing portion 232 is, for example, a hemispherical rubber block or a cubic rubber block. A first mounting hole is formed in the side wall of the pressing plate 21 opposite to the product to be detected, that is, a first mounting hole is formed in the side wall of the pressing plate 21 in contact with the product to be detected, and the pressing member body 231 is mounted in the first mounting hole. The pressing portion 232 of the pressing member 23 is arranged between the pressing plate 21 and the product to be detected. It can be understood that when the pressing assembly 2 presses the product to be detected, the pressing portion 232 will contact the product to be detected before the pressing plate 21 and will be elastically deformed. Through the above arrangement, the pressing member 23 can be elastically deformed when the pressing assembly 2 presses the product to be detected, and the structure is simple and convenient for processing and manufacturing. In addition, through the above arrangement, when the pressing portion 232 is damaged or the material of the pressing portion 232 is aged after long-term use, the pressing member 23 can be directly replaced, which is convenient for maintenance and repair.
[0038] In some embodiments, in combination with Figure 3 、 Figure 4 As shown, a second mounting hole is formed in the pressing plate 21 and communicates with the first mounting hole. The opening direction of the second mounting hole is arranged at an angle with the opening direction of the first mounting hole, for example, the angle between them is 90°, in other words, the center line of the second mounting hole is perpendicular to the center line of the first mounting hole. A fastener 25 is arranged in the second mounting hole and can abut against the pressing member body 231. The fastener 25 is, for example, a rubber plunger or a bolt. It can be understood that by tightening or loosening the fastener 25, the pressing member body 231 can be abutted or loosened. Through the above arrangement, when the fastener 25 is not abutted against the pressing member body 231, the pressing member body 231 can move along the extension direction of the first mounting hole, that is, the size of the pressing member body 231 mounted in the first mounting hole can be adjusted, and then the size of the pressing member 23 protruding from the first mounting hole can be adjusted. Thus, the pressing assembly 2 can flexibly adjust the size of the pressing member 23 protruding from the first mounting hole on the pressing plate 21, and then can adapt to products to be detected of different sizes (thicknesses), and the applicability of the clamping device is improved.
[0039] In some embodiments, a buffer element, such as a spring or a rubber pad, is provided between the clamping body 231 and the clamping portion 232. This buffer element provides cushioning when the clamping assembly 2 clamps the product to be tested, preventing excessive pressure and damage. It also provides elastic force to the clamping portion 232, allowing for better contact between the clamping portion 232 and the product. It is easy to understand that this buffer element provides cushioning through elastic deformation. Therefore, depending on actual usage requirements, the clamping portion 232 of the clamping assembly 23 can be made of an elastic material, or a buffer element can be provided only between the clamping portion 232 and the clamping body 231, or both can be provided, with the clamping portion 232 of the clamping assembly 23 made of an elastic material. This allows for better elastic deformation and cushioning effects. Those skilled in the art can flexibly choose the appropriate setting based on actual usage requirements.
[0040] In some embodiments, combined with Figure 5 , Figure 6 As shown, the locking member 22 includes a latch seat 221, a latch 222, and an elastic member 224.
[0041] like Figure 6 As shown, the latching seat 221 is fixedly connected to the pressure plate 21. Specifically, the latching seat 221 includes a fixing member and support members disposed at opposite ends of the fixing member, wherein the fixing member is fixedly connected to the side wall of the pressure plate 21.
[0042] like Figure 6 As shown, the aforementioned buckle 222 is rotatably connected to the aforementioned buckle base 221 via a buckle shaft 223. Specifically, the two support members of the aforementioned buckle base 221 have pivot holes, and the buckle 222 has a through hole. The buckle shaft 223 passes through both pivot holes on the two support members and the through hole on the buckle 222, thereby achieving a rotatable connection between the buckle 222 and the buckle base 221. One end of the aforementioned buckle 222 is a locking end 2221, and the other end is an actuating end 2222. The locking end 2221 is used to realize the locking function. The locking end 2221 is, for example, hook-shaped. The aforementioned buckle shaft 223 is located between the locking end 2221 and the actuating end 2222 of the buckle 222, so that the locking end 2221 and the actuating end 2222 of the buckle 222 form a lever structure through the buckle shaft 223.
[0043] The elastic element 224 is disposed between the actuating end 2222 of the buckle 222 and the buckle seat 221, and the elastic element 224 always has the tendency to push against the actuating end 2222, thereby enabling the locking end 2221 of the buckle 222 to engage with the base plate 1.
[0044] In the clamping device, the structure of the locking member 22 is provided as the buckle seat 221 fixedly connected with the pressing plate 21, the buckle 222 rotatably connected with the buckle seat 221 through the buckle shaft 223, and the elastic member 224 arranged between the action end 2222 of the buckle 222 and the buckle seat 221. When the action end 2222 of the buckle 222 is pushed by the elastic member 224, the buckle 222 can be clamped with the bottom plate 1, and the pressing plate 21 and the bottom plate 1 are locked. The structure is simple and convenient to use.
[0045] In some embodiments, as shown in Figure 2 The bottom plate 1 is provided with a locking groove 12 corresponding to the locking member 22, that is, the orthographic projection of the locking member 22 on the bottom plate 1 is located in the locking groove 12, so that the locking member 22 can be normally locked with the locking groove 12. A first clamping protrusion 121 is arranged in the locking groove 12, which can lock the pressing plate 21 and the bottom plate 1 by clamping and cooperating with the locking end 2221 of the buckle 222. Specifically, when it is desired to lock the pressing plate 21 and the bottom plate 1, the action end 2222 of the buckle 222 can be manually pushed by the staff to compress the elastic member 224 and overcome the elastic force of the elastic member 224 to move in the direction close to the buckle seat 221. At this time, the locking end 2221 of the buckle 222 moves away from the buckle seat 221 under the action of the lever structure formed by the locking end 2221 and the action end 2222 through the buckle shaft 223. In this way, the locking end 2221 of the buckle 222 is dislocated in the vertical direction with the first clamping protrusion 121 in the locking groove 12, so that the locking member 22 can smoothly extend into the limiting groove, and the pressing assembly 2 can be smoothly pressed on the product to be detected. After the pressing operation on the product to be detected is completed, the staff can stop pushing the action end 2222 of the buckle 222. At this time, the action end 2222 of the buckle 222 moves away from the buckle seat 221 under the action of the elastic force of the elastic member 224. At this time, the locking end 2221 of the buckle 222 moves close to the buckle seat 221 under the action of the lever structure formed by the locking end 2221 and the action end 2222 through the buckle shaft 223. In this way, the locking end 2221 of the buckle 222 can contact (abut) the first clamping protrusion 121 in the locking groove 12 in the vertical direction, thereby achieving the locking of the pressing plate 21 and the bottom plate 1.
[0046] In some embodiments, as shown in Figure 2As shown, the bottom plate 1 is provided with a locking protrusion 13, which is provided correspondingly with the locking piece 22, that is, the normal projection figure of the locking piece 22 on the bottom plate 1 is located within the normal projection figure of the locking protrusion 13 on the bottom plate 1, so that the locking piece 22 can be normally locked with the locking protrusion 13. The locking protrusion 13 is provided with a second clamping protrusion 131, which can be locked with the locking end 2221 of the buckle 222 to lock the pressing plate 21 and the bottom plate 1. As to how the second clamping protrusion 131 cooperates with the buckle 222 to lock the pressing plate 21 and the bottom plate 1, reference can be made to the principle of how the first clamping protrusion 121 cooperates with the buckle 222 to lock the pressing plate 21 and the bottom plate 1, which will not be described herein again.
[0047] It can be understood that the locking groove 12 and the locking protrusion 13 can be set according to actual use requirements. For example, when the size (thickness) of the product to be detected in the placing groove 11 is small, that is, the product to be detected is lower than the groove body of the placing groove 11, the locking groove 12 can be correspondingly provided on the bottom plate 1 to shorten the distance between the pressing plate 21 and the product to be detected, so that the pressing and fixing effect of the pressing assembly 2 is better. When the size (thickness) of the product to be detected in the placing groove 11 is large, that is, the product to be detected protrudes from the placing groove 11, the locking protrusion 13 can be correspondingly provided on the bottom plate 1 to increase the distance between the pressing plate 21 and the product to be detected, so that the pressing plate 21 of the pressing assembly 2 can be smoothly locked with the bottom plate 1. According to actual use requirements, the locking groove 12 can be provided on the bottom plate 1, or the locking protrusion 13 can be provided on the bottom plate 1, or the locking groove 12 and the locking protrusion 13 can be provided on the bottom plate 1. It can be understood that when the locking groove 12 and the locking protrusion 13 are provided on the bottom plate 1, the specific setting mode is, for example, that two pressing assemblies 2 are provided in the clamping device, the locking piece 22 of one pressing assembly 2 is provided correspondingly with the locking groove 12, and the locking piece 22 of the other pressing assembly 2 is provided correspondingly with the locking protrusion 13, rather than that the locking piece 22 of a single pressing assembly 2 is provided correspondingly with both the locking groove 12 and the locking protrusion 13.
[0048] In the above clamping device, by providing the locking groove 12 with the first clamping protrusion 121 and / or the locking protrusion 13 with the second clamping protrusion 131 on the bottom plate 1, the locking end 2221 of the locking piece 22 can be cooperated with the first clamping protrusion 121 or the second clamping protrusion 131 to lock the pressing plate 21 and the bottom plate 1, which is simple in structure, convenient to use and easy to manufacture.
[0049] It can be understood that, as Figure 1As shown, each pressing assembly 2 can include a plurality of locking members 22. For example, each pressing assembly 2 includes two locking members 22, which are arranged at opposite ends of the pressing plate 21, so that the locking members 22 can lock the opposite ends of the pressing plate 21 and the bottom plate 1 at the same time, thereby improving the locking strength between the pressing plate 21 and the bottom plate 1, and further improving the pressing and fixing effect on the product to be detected.
[0050] In some embodiments, in combination with Figure 2 、 Figure 5 As shown, the pressing plate 21 is provided with a positioning hole 24, and the bottom plate 1 is provided with a first positioning member 14, which is connected to the bottom plate 1 by, for example, a screw. The first positioning member 14 can be inserted into the positioning hole 24 to position the pressing plate 21. Specifically, the first positioning member 14 has a rod-shaped structure, and the cross-sectional shape of the rod-shaped structure is, for example, circular, oval, or rectangular. The shape and size of the positioning hole 24 are adapted to the first positioning member 14, and the positioning hole 24 is arranged opposite to the first positioning member 14, i.e., the center line of the positioning hole 24 is arranged coaxially with the axis of the first positioning member 14, so that the first positioning member 14 can be smoothly inserted into the positioning hole 24. The positioning hole 24 can position the pressing plate 21, and further ensure that the pressing members 23 on the pressing plate 21 can accurately press the product to be detected, thereby improving the pressing and fixing effect on the product to be detected, and the structure is simple and easy to manufacture.
[0051] It can be understood that, in combination with Figure 1 、 Figure 2 As shown, the number of the positioning holes 24 can be two, which are arranged at the two ends of the pressing plate 21 along the second direction X2. Adaptively, the number of the first positioning members 14 can also be two, which are arranged opposite to the two positioning holes 24. In this way, the positioning effect of the pressing plate 21 can be improved.
[0052] In some embodiments, as Figure 2As shown, the bottom plate 1 is provided with a second positioning member 15, which is connected with the bottom plate 1, for example, by bolts, and abuts against the product to be detected when the pressing plate 21 presses the product to be detected. Specifically, the second positioning member 15 has a strip-shaped structure, which extends in the same direction as the pressing assembly 2, i.e., in the second direction X2. Meanwhile, the orthographic projection of the second positioning member 15 on the bottom plate 1 is close to the contour of the orthographic projection of the product to be detected on the bottom plate 1, so that the second positioning member 15 can abut against the product to be detected when the pressing plate 21 presses the product to be detected, thereby limiting the product to be detected on one side in the first direction X1, and further ensuring the pressing and fixing effect of the pressing plate 21 on the product to be detected, which is simple in structure and easy to use.
[0053] In some embodiments, as Figure 2 As shown, the bottom plate 1 is provided with a third positioning member 16, which is connected with the bottom plate 1, for example, by bolts, and is arranged at the opening of the placing groove 11 and can abut against the product to be detected in the placing groove 11 to position the product to be detected. Specifically, the third positioning member 16 has a plate-shaped structure, which can cover at least one end of the placing groove 11, so that the product to be detected is placed in the placing groove 11, and after the third positioning member 16 is arranged at the opening of the placing groove 11, the third positioning member 16 can press and fix the third positioning member 16 in the vertical direction, which is used in cooperation with the pressing assembly 2 to further improve the pressing and fixing effect on the product to be detected, which is simple in structure and easy to use. Meanwhile, the third positioning member 16 can limit the other side of the pressing plate 21 in the first direction X1, which can improve the limiting effect of the pressing plate 21 in cooperation with the second positioning member 15, avoid slight deviation of the pressing plate 21, and further ensure the pressing and fixing effect of the pressing plate 21 on the product to be detected.
[0054] In some embodiments, as Figure 2As shown, the bottom plate 1 is provided with a fourth positioning member 17, which is arranged on the groove bottom of the placing groove 11 and can slide relative to the groove bottom of the placing groove 11. Specifically, the second positioning member 15 is in the form of a plate or a block, the fourth positioning member 17 is provided with a sliding block (for example, a dovetail sliding block or an inverted "T" sliding block) on the side wall in contact with the groove bottom of the placing groove 11, a sliding groove is formed on the groove bottom of the placing groove 11 and is matched with the sliding block, and the extension direction of the sliding groove is the same as the extension direction of the placing groove 11. Through the cooperation of the sliding block on the fourth positioning member 17 and the sliding groove on the groove bottom of the placing groove 11, the fourth positioning member 17 can slide relative to the groove bottom of the placing groove 11. In addition, the fourth positioning member 17 is provided with a locking through hole with an internal thread, the opening direction of the locking through hole is perpendicular to the groove bottom of the placing groove 11, a bolt is arranged in the locking through hole, one end of the bolt can abut against the groove bottom of the placing groove 11 through the fourth positioning member 17, and the position of the fourth positioning member 17 can be locked or moved by tightening or loosening the bolt. Through the above arrangement, when the placing groove 11 on the bottom plate 1 places products to be detected with different sizes (lengths), the fourth positioning member 17 can be adjusted to position and fix the products to be detected with different sizes (lengths), so that the clamping device can adapt to products to be detected with different sizes (lengths), and the applicability of the clamping device is improved.
[0055] It is easy to understand that the third positioning member 16 and the fourth positioning member 17 can be arranged separately or simultaneously, that is, the bottom plate 1 can be provided with only the third positioning member 16, only the fourth positioning member 17, or both the third positioning member 16 and the fourth positioning member 17. When the bottom plate 1 is provided with both the third positioning member 16 and the fourth positioning member 17, the effect of pressing and fixing the product to be detected can be further improved, and a person skilled in the art can make flexible selection according to actual use requirements, and this is not limited here.
