Description

Technical Field

[0001] The utility model relates to the field of product production and transportation, in particular to a clamping device. Background Art

[0002] During the production and transportation of products, it is often necessary to fix the products to carriers or platforms. For example, during transportation, especially in long-distance transportation or bumpy environments, if the product is not properly fixed, it may move, collide or even fall off, causing damage. Clamping can effectively avoid this situation. For another example, in an automated production line or logistics processing, the product is firmly fixed on the carrier, which can speed up the processing speed of automated equipment, reduce positioning time, and improve overall operating efficiency. For processing or assembly processes that require precise positioning, such as laser cutting, welding, assembly, etc., clamping the product can ensure the position accuracy of each operation and improve the processing quality. In addition, by clamping and fixing, the damage caused by vibration and impact to the product can be reduced, which is especially important for precision instruments and fragile items, and helps to keep the product intact. However, existing clamping devices often focus on pressing, but are not convenient for product access. When separating the product from the platform, the clamping device will cause obstacles.

If there is a description of "first" or "second", it is only used to distinguish the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0027] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0028] refer to Figures 1 to 4 , an embodiment of the present application provides a clamping device 100. In order to better illustrate the clamping device 100 provided in the embodiment of the present application, a rectangular coordinate system is established with the width direction of the clamping device 100 as the X-axis, the length direction as the Y-axis, and the height direction as the Z-axis. The clamping device 100 includes: a carrier 110 and a clamping mechanism 120. Among them, the carrier 110 is used to carry the product 200. The clamping mechanism 120 includes at least one clamping member 121. The clamping member 121 is rotatably connected to the carrier 110, and the clamping member 121 rotates closer to or away from the carrier 110 to press or release the product 200 from the carrier 110.

[0029] The clamping device 100 provided in the present application has a product 200 placed on a carrier 110, and is rotatably connected to the carrier 110 via a clamping member 121 of a clamping mechanism 120. The clamping member 121 rotates toward or away from the carrier 110 to clamp or loosen the product 200 and the carrier 110. On the one hand, a clamping effect can be achieved. On the other hand, by rotating away from the carrier 110, the entire product 200 can be exposed, and there is no obstruction when taking the product 200, which can facilitate the taking and placing of the product 200, save space, and facilitate production.

[0030] In a feasible embodiment, the clamping mechanism 120 also includes a drive assembly 122. The drive assembly 122 is connected to the clamping member 121 to provide a driving force for the clamping member 121 to move. Exemplarily, the drive assembly 122 can be a rotary drive assembly 122 directly. For example, a rotary motor, the clamping member 121 can be directly connected to the output end of the rotary motor, and the rotary motor directly drives the clamping member 121 to rotate, and the rotary motor can realize the clamping member 121 close to or away from the product 200 by forward and reverse rotation. As another example, the drive assembly 122 can also be driven by a transmission structure to achieve rotation. For example, the clamping member 121 can be driven by a gear or a track to rotate. Such a method can realize the rotation of the clamping member 121 and the direct drive of the drive device to rotate it. Exemplarily, the drive assembly 122 can also be a linear drive assembly 122 to provide a driving force for the movement of the clamping member 121, and the clamping member 121 is rotated by cooperating with other mechanisms.

[0031] In a possible implementation, Figure 1 and Figure 2 As shown, the clamping mechanism 120 also includes a track plate 123. The track plate 123 is arranged between the driving assembly 122 and the clamping member 121. The track plate 123 is used to drive the clamping member 121 to move and guide the moving trajectory of the clamping member 121 under the drive of the driving assembly 122. The track plate 123 can achieve high-precision linear position control. Exemplarily, under the drive of the linear motor, the track plate 123 can provide smooth, jitter-free linear motion; Exemplarily, the track plate 123 can be designed as a single-axis or multi-axis (such as XY, XYZ) configuration to achieve motion control of complex spatial trajectories. The track plate 123 has a strong load-bearing capacity; the track plate 123 can ensure high repeatability of each movement and improve production efficiency and operation effect.

[0032] In a possible implementation, Figure 1 and Figure 2As shown, the drive assembly 122 includes a drive motor 1221 and an output member 1222. The output member 1222 is arranged between the track plate 123 and the pressing member 121. The output member 1222 drives the track plate 123 to move in the vertical direction under the drive of the drive motor 1221. In this way, the drive motor 1221 is a linear output motor. The linear motor has a simple structure and does not require additional conversion devices (such as gears, belts, screws, etc.) to convert rotary motion into linear motion, which simplifies the system structure, reduces weight, and reduces volume; the linear motor has high positioning accuracy: the linear motor directly generates linear motion, eliminating the error that may be introduced when the traditional rotary motor converts linear motion through the transmission mechanism, so it can achieve higher positioning accuracy. Combined with microcomputer control, the overall positioning accuracy of the system can be further improved. The linear motor has fast response speed, high sensitivity, and good follow-up performance: the linear motor can easily realize the magnetic suspension of the mover, so that the mover and the stator maintain a constant non-contact air gap, thereby eliminating friction resistance and improving the response speed, sensitivity and follow-up performance of the system. Linear motors are safe, reliable and have a long service life: Since linear motors transmit force without contact, mechanical friction loss is almost zero, the failure rate is low, and they are almost maintenance-free, so they have a long service life and high reliability. Linear motors have excellent dynamic performance: The acceleration capability and maximum speed of linear motors are often better than traditional rotary motors because they are not limited by centrifugal force and are suitable for high-speed linear motion. Linear motors are highly adaptable: The stroke of linear motors is not limited and can be customized as needed. They are suitable for long-stroke applications and are more advantageous in situations where precise control of force or position is required. Finally, linear motors are low-noise: Since there is no mechanical contact, linear motors have low noise during operation, which is particularly suitable for environments with strict requirements for noise control.

[0033] In a possible implementation, Figure 1 and Figure 2 As shown, the clamping mechanism 120 includes two clamping members 121. The two clamping members 121 are connected to the two ends of the output member 1222 along the width direction of the carrier 110. In this way, by providing two clamping members 121, the product 200 and the carrier 110 can be clamped from two positions, which increases the stability and reliability of the operation of the clamping device 100. Further, when the clamping mechanism 120 includes two clamping members 121, the corresponding track plates 123 are also two, and the structures at both ends of the output member 1222 are the same or symmetrical.

[0034] In a possible implementation, Figure 1 and Figure 2As shown, a track groove 1231 is provided on the track plate 123. A connecting assembly 124 is provided in the track groove 1231. The two ends of the clamping member 121 respectively have a connecting portion 1211 and an abutting portion 1213. The abutting portion 1213 is used to abut the product 200 on the carrier 110. The connecting portion 1211 is connected to the connecting assembly 124. The connecting assembly 124 is used to drive the connecting portion 1211 of the clamping plate to move along the track groove 1231. Through the track groove 1231, the connecting end of the clamping member 121 is fixed in the track groove 1231 and slidably connected along the track groove 1231, so that the clamping member 121 can stably move along the track groove 1231. The track groove 1231 can guide and support the connecting portion 1211 of the clamping member 121 to move accurately and smoothly along a predetermined straight path. Track groove 1231 can ensure the flatness and straightness of the track surface through precise processing means, thereby achieving high-precision linear motion; its structural design provides good rigidity, supports heavy loads and reduces deformation. Furthermore, the connection form between track groove 1231 and connecting assembly 124 can be a ball or roller circulation system, which can greatly reduce movement friction, make movement smoother, and reduce energy consumption and wear. Track groove 1231 has a simple structure and is easy to assemble. Track groove 1231 can also include a self-lubricating system, which reduces maintenance requirements and extends service life through the recycling of grease or solid lubricants. Furthermore, according to application requirements, track groove 1231 has a variety of models and specifications to choose from, including different lengths, widths, load capacities, accuracy levels, etc., as well as various structural forms such as open, closed, and dustproof cover plates to adapt to different environments and usage conditions.

[0035] In a possible implementation, Figure 1 and Figure 2 As shown, the pressing member 121 has a bending portion 1212. The bending portion 1212 is arranged between the connecting portion 1211 and the abutting portion 1213. The bending portion 1212 has a bending structure. The pressing member 121 rotates around the bending portion 1212 under the drive of the driving assembly 122. The bending portion 1212 can facilitate the rotation of the pressing member 121 and save space. At the same time, the bending structure can enable the pressing member 121 to form a stable structural shape, thereby improving the structural stability of the pressing member 121.

[0036] In a possible implementation, Figure 1 and Figure 2As shown, the bending portion 1212 is provided with a mounting through hole 1214. A rotating shaft 133 is arranged in the mounting through hole 1214. The rotating shaft 133 is connected to the carrier 110. The clamping member 121 rotates around the rotating shaft 133. In this way, the clamping member 121 can be connected to the carrier 110 more stably through the shaft hole connection. Further, the matching mode of the rotating shaft 133 and the mounting through hole 1214 can be a clearance fit, an interference fit or a transition fit. As an example, the matching mode of the rotating shaft 133 and the mounting through hole 1214 can be a clearance fit: the existence of the clearance allows relatively easy assembly and disassembly, and allows slight relative movement between the components, and the clearance can also store lubricating oil to compensate for thermal expansion or manufacturing errors. As an example, the matching mode of the rotating shaft 133 and the mounting through hole 1214 can be a transition fit, which may have a slight clearance or a slight interference, depending on which tolerance range the actual size falls within. Transition fit is suitable for connections that require precise alignment but also require detachability. As an example, the shaft 133 and the mounting through hole 1214 may be fitted with an interference fit, which requires a large force to assemble, and is usually assembled by means of pressure, thermal expansion or contraction. Interference fit provides a fixed and reliable connection, and is suitable for situations where torque needs to be transmitted or heavy loads need to be borne. Interference fit can rely on the interference to transmit loads without the need for additional fasteners.

[0037] In a feasible embodiment, the abutment 1213 of the clamping member 121 has an extrusion block (not shown). The extrusion block is made of rubber, elastomeric or POM plastic. The use of extrusion blocks made of these elastic materials can make the contact between the abutment 1213 and the product 200 flexible. The elastic material can adapt to different deformations and can still return to its original state even after experiencing a large deformation; the elastic material can absorb and disperse external forces, reduce impact and vibration, protect the equipment from damage, avoid damage to the product 200 caused by extrusion, and also reduce wear and tear, extending the service life of the clamping member 121. Elastic materials can effectively absorb sound waves, reduce the noise generated by friction between structures, and create a quieter working environment.

[0038] In a feasible implementation, as 1 and Figure 2 As shown, the clamping device 100 includes two clamping mechanisms 120. The two clamping mechanisms 120 are arranged oppositely on both sides of the carrier 110 along the length direction. In this way, the clamping effect of the clamping device 100 on the product 200 and the carrier 110 can be further improved by the two clamping mechanisms 120, thereby improving the operating stability and effect of the device.

[0039] Furthermore, if Figures 1 to 4As shown, the clamping device 100 includes a frame 130. The frame 130 includes two supporting members 131 arranged in pairs, and the two supporting members 131 are respectively connected to the two clamping mechanisms 120 and the carrier 110, and are used to support the carrier 110 and connect the clamping mechanism 120 to the carrier 110. Two connecting members 132 are fixed on the two supporting members 131 respectively. The two clamping mechanisms 120 are fixed on the two connecting members 132. Specifically, the fixed end of the driving motor 1221 of the driving assembly 122 is fixed on the connecting member 132, and the output end of the driving motor 1221 is connected to the output member 1222. The output member 1222 is slidably connected to the supporting member 131 in the vertical direction. Specifically, the sliding connection mentioned here can be achieved by a slide rail 134 and a slider 135. The slide rail 134 is fixed to the supporting member 131 in the vertical direction. The slider 135 is fixedly connected to the output member 1222, so that the slider 135 and the slide rail 134 can further guide the direction of the driving force output by the driving motor 1221. The output member 1222 is fixedly connected to the track plate 123 on both sides along the width direction of the carrier 110. The connecting portion 1211 of the clamping member 121 is connected to the connecting component 124 in the track groove 1231 of the track plate 123. The bent portion 1212 of the clamping member 121 is connected to the rotating shaft 133 on the connecting member 132 through the mounting through hole 1214. Specifically, the connecting member 132 is provided with a mounting groove in the vertical direction for accommodating the portion of the mounting through hole 1214 of the bent portion 1212. At the same time, the rotating shaft 133 passes through the mounting through hole 1214 and is fixed in the mounting groove along the width direction of the carrier 110. In the clamping state, the contact portion 1213 of the clamping member 121 abuts against the product 200 and clamps the product 200 against the carrier 110. In the loosening state, the clamping member 121 rotates away from the product 200, and the contact portion 1213 is not located above the product 200 in the vertical direction, which facilitates the taking of the product 200. Specifically, the working process of the clamping mechanism from the clamping state to the loosening state is as follows: the driving motor 1221 drives the output member 1222 to move downward in the vertical direction, and the connecting portion 1211 of the clamping member 121 moves along the track groove 1231 toward the direction close to the supporting member 131. Since the bending portion 1212 of the clamping member 121 is fixed, the contact portion 1213 of the clamping member 121 rotates away from the product 200, thereby achieving the effect of loosening the product 200. It can be known that the working process of the clamping mechanism from the loosened state to the clamped state is: the driving motor 1221 drives the output member 1222 to move upward in the vertical direction, and the connecting part 1211 of the clamping member 121 moves along the track groove 1231 in the direction away from the support member 131. Since the bending part 1212 of the clamping member 121 is fixed, the abutting part 1213 of the clamping member 121 rotates in the direction close to the product 200, thereby achieving the effect of clamping the product 200.

[0040] Further, the carrier 110 may be fixed on the frame 130, or may be detachably separated from the frame 130. The carrier 110 is a platform for carrying, fixing, transporting or operating the product 200, which will not be described in detail herein.

[0041] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
