[0002] With the rapid development of the technology industry, the requirements for manufacturing processes are becoming increasingly stringent. However, different specifications of material trays are often used in the production process. Due to the inconsistent inner diameter of the trays, it may be difficult for the trays to fit tightly with the production equipment. For example, in the production process of Surface Mount Technology (SMT), the inconsistent inner diameter of the trays prevents them from fitting properly with the rotating shaft of the mounting equipment. Furthermore, due to the inconsistent specifications of the production equipment, the shaft dimensions of the equipment are also inconsistent, making it difficult to quickly change between different sized trays, reducing production quality and efficiency, and increasing production costs. Utility Model Content

[0003] In view of the above, it is necessary to provide a clamping device and production equipment that can adaptively adjust the size to achieve a tight connection of the material tray.

[0007] In one possible design, the adjustable spring includes an elastic part, a main body, and a support part. The elastic part is located on the side of the main body near the center of the annular base, and the support part is located on the side of the main body away from the center of the annular base. The elastic part and at least a portion of the main body are housed in a first receiving groove.

The diameter of the elastic part is larger than the inner diameter of the channel, and the diameter of the elastic part is smaller than the inner diameter of the bottom groove. The height of the elastic part is smaller than the depth of the bottom groove.

[0009] In one possible design, the surface of the support portion on the side away from the main body is an arc-shaped surface, and the arc-shaped surface covers the channel.

[0011] In one possible design, the clamping device further includes a cover ring disposed on the first side; the outer radius of the cover ring is equal to the outer radius of the annular base, and the inner radius of the cover ring is equal to the inner radius of the annular base.

[0026] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0027] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise.

[0029] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0030] With the rapid development of the technology industry, the requirements for manufacturing processes are becoming increasingly stringent. However, different specifications of material trays are often used in the production process. Due to the inconsistent inner diameter of the trays, it may be difficult for the trays to fit tightly with the production equipment. For example, in the production process of Surface Mount Technology (SMT), the inconsistent inner diameter of the trays prevents them from fitting properly with the rotating shaft of the mounting equipment. Furthermore, due to the inconsistent specifications of the production equipment, the shaft dimensions of the equipment are also inconsistent, making it difficult to quickly change between different sized trays, reducing production quality and efficiency, and increasing production costs.

[0031] Based on this, this application provides a clamping device and production equipment that can adaptively adjust the size to achieve a tight connection of the material tray.

[0032] Next, a clamping device provided in the embodiments of this application will be further described. It is understood that the clamping device provided in this application can be applied to production equipment, as illustrated in the following embodiments using mounting equipment used in the surface mount technology (SMT) production process.

[0033] Please see Figure 1 This illustration shows a structural schematic diagram of a clamping device provided in one embodiment of this application. Figure 1 As shown, the clamping device 10 includes an annular base 101 and an adjustable spring block 102. The outer peripheral wall 101a of the annular base 101 is provided with a first receiving groove 103, and the adjustable spring block 102 is used to extend and retract on the surface of the outer peripheral wall 101a.

[0034] In one embodiment of this application, the first receiving groove 103 includes a bottom groove 1031 and a channel 1032. The end of the bottom groove 1031 away from the outer peripheral wall 101a is closed, and the end of the bottom groove 1031 near the outer peripheral wall 101a communicates with the channel 1032. The opening of the channel 1032 is exposed outside the outer peripheral wall 101a. Understandably, the adjustable spring block 102 can extend and retract at least partially within the first receiving groove 103. The bottom groove 1031 can be a square dovetail groove, or it can be any other shape that allows the adjustable spring block 102 to move. This application does not limit the specific shape of the bottom groove 1031.

[0035] Please refer to the following: Figure 1 and Figure 2 The adjustable spring block 102 includes an elastic portion 1021, a main body portion 1022, and a support portion 1023. The elastic portion 1021 is disposed on the side of the main body portion 1022 near the center O of the annular base 101, and the support portion 1023 is disposed on the side of the main body portion 1022 away from the center O of the annular base 101. The elastic portion 1021 and at least a portion of the main body portion 1022 are received within a first receiving groove 103. Understandably, the elastic portion 1021 and at least a portion of the main body portion 1022 slide within the first receiving groove 103 in a direction near or away from the center O of the annular base 101, so as to interact with the tray 20 (see...). Figure 5 The support portion 1023 protrudes from the outer peripheral wall 101a and moves along the direction of the center O of the annular base 101 from the outside of the outer peripheral wall 101a.

[0036] In one embodiment of this application, as Figure 3 As shown, the inner diameter D3 of the channel 1032 is smaller than the inner diameter D1 of the bottom groove 1031, the diameter D2 of the elastic part 1021 is larger than the inner diameter D3 of the channel 1032, and the diameter D2 of the elastic part 1021 is smaller than the inner diameter D1 of the bottom groove 1031; the height H2 of the elastic part 1021 is smaller than the depth H1 of the bottom groove 1031. Understandably, the volume of the bottom groove 1031 is larger than the volume of the elastic part 1021, and the elastic part 1021 can slide within the bottom groove 1031 in a direction close to or away from the center O of the annular base 101, but cannot slide within the channel 1032. The difference between the width D2 of the elastic part 1021 and the width D1 of the bottom groove 1031 is within a preset range, for example, 0.2 mm. The range of the difference between the height H2 of the elastic part 1021 and the depth H1 of the bottom groove 1031 is set according to the inner diameter of the tray 20. This application does not limit the specific setting range of the difference; it can be set according to actual conditions.

[0037] In some embodiments, in a cross-sectional direction perpendicular to the annular section of the annular base 101, the length of the bottom groove 1031 (not shown in the figure) is equal to the length L2 of the channel 1032, and the lengths of the bottom groove 1031 and the channel 1032 are both less than the length L1 of the curved surface of the outer peripheral wall 101a; where length is a distance perpendicular to the annular section. Understandably, the length L1 of the curved surface of the outer peripheral wall 101a, i.e., the thickness of the annular base 101, is greater than the length L2 of the channel 1032 and the length of the bottom groove 1031. The difference between the length L1 of the curved surface of the annular base 101 and the length L2 of the channel 1032 is within a preset range, and this application does not limit the preset range. Thus, in a cross-sectional direction perpendicular to the annular section of the annular base 101, the channel 1032 and the bottom groove 1031 cannot penetrate the entire annular base 101. Figure 4 As shown, the clamping device 10 also includes a cover ring 106, which is disposed on the first side surface. The first receiving groove 103 communicates with the first side surface of the annular base 101, that is, the first receiving groove 103 is connected to the cover ring 106. The outer radius of the cover ring 106 is equal to the outer radius of the annular base 101, and the inner radius of the cover ring 106 is equal to the inner radius of the annular base 101. Understandably, the cover ring 106 can completely cover the side plane of the annular base 101, that is, the annular cross-section. The cover ring 106 and the annular base 101 are detachably connected. Since the channel 1032 and the bottom groove 1031 cannot penetrate the entire annular base 101, relevant technicians can install and / or replace the adjustable spring block 102 by disassembling the cover ring 106. The cover ring 106 blocks the adjustable spring block 102, reducing the probability of the adjustable spring block 102 shifting along the annular cross-section perpendicular to the annular base 101, and reducing the probability of the adjustable spring block 102 detaching from the clamping device 10 during the operation of the production equipment. This effectively ensures the safety and stability of the clamping device 10 during use. Moreover, only one cover ring 106 needs to be installed to reduce the probability of the adjustable spring block 102 shifting, reducing economic costs, ensuring the structural strength of the clamping device 10, and improving the efficiency of the clamping device 10.

[0038] Please refer to it again. Figure 2The side of the support portion 1023 away from the main body portion 1022 has an arc-shaped surface, and the arc-shaped surface covers the channel 1032. The side of the support portion 1023 away from the main body portion 1022 can be a pseudo-circular structure with an arc matching the material tray 20, so that the support portion 1023 fits snugly against the material tray 20. The elastic portion 1021 has a mounting hole 1021a on the side near the center O of the annular base 101, and an elastic element (not shown in the figure) is provided in the mounting hole 1021a. Understandably, the number of mounting holes 1021a is greater than or equal to the number of elastic elements. The elastic element can be a spring, or other materials or structural components with deformation and recovery capabilities. This application does not limit the specific style of the elastic element. The adjustable spring block 102 can be made of materials such as rubber, plastic, or metal. This application does not limit the specific material of the adjustable spring block 102. Figure 5 As shown, when the tray 20 is fitted onto the clamping device 10, the elastic element deforms under the pressure applied by the tray 20 through the support part 1023. The support part 1023 abuts against the inner wall of the tray 20, thereby achieving a tight fit between the clamping device 10 and the tray 20. The pressure applied to the elastic element by trays 20 with different inner diameters is inconsistent, so the degree of deformation of the elastic element is also inconsistent. This adaptively adjusts the sliding distance of the elastic part 1021 in the bottom groove 1031 along the center O of the annular base 101, realizing personalized adjustment for trays 20 with various inner diameters. This reduces the probability of the tray 20 falling off the clamping device 10 and reduces the possibility of the clamping device 10 changing the shape of the tray 20 during operation, ensuring the safety and stability of the clamping device 10.

[0039] Please refer to it again. Figure 1 The inner peripheral wall of the annular base 101 is also provided with a second receiving groove 104. The clamping device 10 also includes an elastic adjusting member 105. One end of the elastic adjusting member 105 is received in the second receiving groove 104, and the other end of the elastic adjusting member 105 is used to fit against the rotating shaft. The elastic adjusting member 105 is used to extend and retract on the surface of the inner peripheral wall. When the elastic adjusting member 105 is subjected to pressure from the shaft, the elastic adjusting member 105 extends and retracts into the second receiving groove 104.

[0040] Understandably, a plurality of second receiving slots 104 can be provided on the inner peripheral wall of the annular base 101, for example, the number of second receiving slots 104 is 8. This application does not limit the specific number of second receiving slots 104. The number of elastic adjusting members 105 is less than or equal to the number of second receiving slots 104. The surface of the elastic adjusting member 105 protruding from the second receiving slot 104 is a spherical surface. The elastic adjusting member 105 can be a spring-loaded ball, that is, a spring is used to connect the elastic adjusting member 105 and the second receiving slot 104 (e.g., Figure 6As shown), other movable bead structures can also be used. This application does not limit the specific style and quantity of the elastic adjustment element 105. The elastic adjustment element 105 can be made of stainless steel, alloy, or other materials. This application does not limit the specific material of the elastic adjustment element 105. Figure 5 As shown, the rotating shaft 30 passes through the inner circle of the annular base 101. At this time, the elastic adjusting member 105 is compressed into the second receiving groove 104 by the pressure applied by the rotating shaft 30, so that the clamping device 10 can adjust the extension and retraction of the elastic adjusting member 105 according to the size of the rotating shaft 30. This allows it to clamp rotating shafts 30 of various specifications, improves the universality of the clamping device 10, reduces the probability of the clamping device 10 moving on the rotating shaft 30, reduces the use of additional auxiliary devices, facilitates quick replacement of rotating shafts 30 of different specifications, and improves production efficiency and production quality.

[0041] Please refer to it again. Figure 5 An embodiment of this application also provides a production device. Figure 5 A partial structural diagram of a production equipment 1 provided in one embodiment of this application is shown. For example... Figure 5 As shown, the production equipment 1 includes a material tray 20 and a rotating shaft 30. The production equipment 1 also includes a clamping device 10 as described in any of the above embodiments. For the parts that are the same as or corresponding to the previous embodiment, please refer to the corresponding description of the foregoing embodiment. They will not be described in detail below.

[0042] Specifically, the material tray 20 is a tool used in production equipment 1 for storing, handling, and / or transporting materials. The rotating shaft 30 is a component in production equipment 1 used for supporting parts and / or transmitting power, such as a rotating shaft or a fixed shaft. This application does not limit the specific style of the rotating shaft 30. During the production process, the material tray 20 is fitted onto the outer peripheral wall 101a of the clamping device 10. When the material tray 20 is tightly fitted with the clamping device 10, the rotating shaft 30 passes through the inner circle of the clamping device 10 to engage with the inner peripheral wall of the clamping device 10. In this way, the material tray 20, the clamping device 10, and the rotating shaft 30 can achieve close interconnection, thereby achieving stable operation of production equipment 1. The clamping device 10 of this application can effectively adapt to material trays 20 and rotating shafts 30 of various sizes, improving the speed and efficiency of changing material trays 20 and rotating shafts 30, improving the wide applicability of the equipment, and ensuring the stable operation of production equipment 1.

[0043] It should be understood that the various embodiments of this application can be combined arbitrarily, for example, they can be used individually or in combination with each other to achieve different technical effects, and there is no limitation thereto.

[0044] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
