In the following detailed description of the present invention, certain specific details are set forth in detail. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. Well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present invention.

Further, those of ordinary skill in the art will appreciate that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.

Unless the context clearly requires otherwise, throughout the description, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, what is meant is "including, but not limited to".

In the description of the present invention, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

Fig. 1-6 are schematic views of a clamping device according to an embodiment of the present invention. As shown in fig. 1 and 2, the crimping device comprises a frame 1, an intermediate plate 2, a crimping assembly 4 and a power assembly 5. As shown in fig. 3, the crimping assembly 4 includes a crimping main body 41, a follower portion 42, and a crimping blade 43. The follower portion 42 is connected to one end of the crimping body 41 and is located above the crimping body 41, and the crimping blade 43 is connected to the other end of the crimping body 41 and is located below the crimping body 41.

Returning to fig. 1 and 2, the middle plate 2 is rotatably disposed on the frame 1, the middle plate 2 is provided with a plurality of sliding grooves 20, and the different positions of the sliding grooves 20 have different distances from the rotation center of the middle plate 2. The follow-up part 42 of the clamping and pressing assembly 4 is movably arranged in the sliding chute 20, the clamping and pressing main body 41 and the clamping and pressing knife 43 of the clamping and pressing assembly 4 extend out of the sliding chute 20, and the clamping and pressing knife 43 faces to the rotating center of the middle plate 2. The power assembly 5 is movably connected with the middle plate 2 and configured to drive the middle plate 2 to rotate, so as to drive the follow-up portion 42 to slide in the sliding groove 20.

The plurality of chutes 20 are arranged at equal intervals in the circumferential direction of the intermediate plate 2. The number of the clamping components 4 corresponds to the number of the sliding grooves 20 one by one, and the follow-up portion 42 of each clamping component 4 slides in the corresponding sliding groove 20 to drive the clamping knife 43 on each clamping main body 41 to move towards the rotation center of the middle plate 2 along the radial direction of the middle plate 2, so that clamping is realized. Or, the power assembly 5 drives the middle plate 2 to rotate in the opposite direction, and drives the clamping knife 43 to move away from the rotation center of the middle plate 2 along the radial direction of the middle plate 2, so as to realize loosening.

The chute 20 is preferably a curved chute, so that the clamping pressure is the same for products with different shapes and sizes, the force application is uniform, and the mechanism compatibility is higher.

As shown in fig. 1 and 2, in the present embodiment, the crimping assemblies 4 are provided with eight, that is, the crimping device achieves crimping of the product by eight directions of crimping movement. The pressing body 41 has a strip shape or a similar linear structure. To slide in the sliding groove 20, the follower portion 42 is preferably cylindrical or disk-shaped and can be fixedly connected to the clamping body 41 by a fastening member, such as a screw or a bolt. To enable crimping, as shown in fig. 3, the crimping ends 431 of the crimping blades 43 extend beyond the edge of the crimping body 41, and the plurality of crimping blades 43 extend beyond the respective crimping body 41 toward a point where they meet, and move toward the point simultaneously to form a crimp. The nip end 431 may be triangular, rectangular, or other shape that directly contacts and applies nip pressure to the product as the nip blade 43 nips the product in a multi-directional loop. The remaining portion of the crimping blade 43 other than the crimping end 431 may be fixedly attached to the crimping body 41 by a fastener.

In addition, for products with different shapes, when the clamping and pressing knives 43 with different shapes or sizes are required to clamp and press, the clamping and pressing knives 43 are connected with the clamping and pressing main body 41 through fasteners, so that the fasteners can be detached to quickly replace the different clamping and pressing knives 43, and the products with different shapes can be adapted.

In some other alternative implementations, the number of crimping assemblies 4 is not limited to eight, and may be any number. However, in order to achieve a relative crimping movement, the number of crimping assemblies 4 is at least two.

As shown in fig. 1 and 2, the clamping and pressing device may further include a mounting plate 3, the mounting plate 3 is disposed on the middle plate 2, and a plurality of guide grooves 30 corresponding to the sliding grooves 20 one to one are formed thereon, the guide grooves 30 face the rotation center of the middle plate 2, and each guide groove 30 is partially communicated with the corresponding sliding groove 20. The crimping body 41 corresponding to the follower portion 42 of each chute 20 is located in the guide groove 30 corresponding to the chute 20, and partially protrudes from the guide groove 30. When the following portion 42 moves along the sliding groove 20, the clamping main body 41 is driven to move along the guide groove 30 toward or away from the rotation center of the middle plate 2, and clamping or releasing can be achieved.

The mounting plate 3 may provide a location for the installation of the crimp assembly 4, i.e. the crimp body 41 and the follower 42 of the crimp assembly 4 have a set of corresponding guide slots 30 and runners 20 into which the crimp assembly 4 may be fitted during installation.

As shown in fig. 1 and 2, a limiting member 31 may be further disposed between each of the crimping main bodies 41, and the limiting member 31 is used for limiting the crimping direction of the crimping assembly 4. The limiting member 31 can be fixedly connected to the mounting plate 3 by a fastener, and the side surface of the limiting member is in sliding fit with the side surface of the adjacent clamping main body 41, so that the clamping main body 41 can only move along the side surface of the limiting member 31 when moving along the guide groove 30.

In the present embodiment, the limiting member 31 is provided as an isosceles triangular plate. When the limiting member 31 is disposed between the two clamping bodies 41, the vertex angle of the isosceles triangular plate points to the rotation center of the middle plate 2, and the two side edges are respectively attached to the clamping bodies 41 on the two sides in a sliding manner, so that when the clamping body 1 moves, the isosceles triangular plate moves in the direction from the side edge to the vertex angle (i.e., the rotation center of the middle plate 2). That is, the guide groove 30 and the stopper 31 together define that the moving direction of the crimping assembly 4 is in the radial direction of the intermediate plate 2, i.e., the direction of crimping movement.

As shown in fig. 3, the clamping assembly 4 may further include a stopper 411, a stop member 412 and a scale 413 on the clamping main body 41. The stop 411 may be fixed on the clamping main body 41 by a fastener, the stop member 412 is movably disposed through the stop 411, the graduated scale 413 is fixedly disposed through the stop 411, and both the stop member 412 and the graduated scale 413 have one end abutting against the clamping knife 43, and more specifically, the other end abutting against the clamping knife 43 opposite to the clamping end 431.

The stop member 412 is movable in the stopper 411 in the clamping direction, and the clamping blade 43 is pushed by the abutting end to move the clamping blade 43 in the clamping direction. The scale 413 is arranged in parallel on one side of the stop member 412, and the direction of the scale is also parallel to the clamping movement, when the stop member 412 pushes the clamping knife 43 to adjust the movement distance, that is, the corresponding clamping depth, can be read through the scale 413.

The required clamping depth is different for products with different shapes and sizes, and when the clamping depth reaches the preset depth through reading by the graduated scale 413, the stop piece 412 is stopped and fixed, so that the stop clamping knife 43 is stopped, and the product is clamped. Wherein, the preset depth refers to the clamping degree required by the clamping processing of the parts to be clamped of different products.

The scale 413 may be a micrometer so that the accuracy of the nip depth adjustment is higher. In some other alternative implementations, the scale 413 may be another measuring tool, or the scale 413 may not be provided, and the adjustment of the riveting depth is achieved only by the stop member 412.

As shown in fig. 4, the stopper 411 may further include an elastic member 8. The elastic member 8 is disposed along the radial direction of the middle plate 2, one end of which abuts against the stopper 411, and the other end of which is fixed to the edge of the middle plate 2. That is, the fixed end of the elastic member 8 is farther from the nip region (the rotation center of the intermediate plate 2 in the present embodiment) than the end abutting against the stopper 411. The elastic member 8 is in a compressed state, and then the elastic member 8 exerts a force towards the clamping area on the stopper 411, and the stopper 411 drives the clamping assembly 4 fixedly connected with the stopper 411 to integrally press towards the clamping area, so as to push the follow-up portion 42 to press on the groove wall of the sliding groove 20, thereby avoiding a gap between the follow-up portion 42 and the sliding groove 20. The mounting plate 3 is not shown in fig. 4 to more clearly show the connection between the follower portion 42 and the chute 20. The follow-up part 42 originally forms clearance fit with the sliding chute 20, and after the elastic part 8 is arranged, the follow-up part is attached to the chute wall of the sliding chute 20 close to one side of the clamping area under the action of the elastic part 8, so that the clearance is eliminated, and the precision of the whole clamping movement of the follow-up part 42 along the sliding chute 20 to drive the mechanism can be improved.

As shown in fig. 1 and 2, a first through hole 21 is formed in the center of the middle plate 2, a second through hole 32 is formed in the center of the mounting plate 3, a third through hole 113 is formed in the frame 1, and the first through hole 21, the second through hole 32 and the first through hole 21 are communicated with each other.

The crimping device further comprises a first bearing 61, a second bearing 63, a rotating shaft 6 and a connecting piece 7, wherein the rotating shaft 6 is provided with a first end 62 and a second end 64 which are opposite, the first end 62 is arranged in the third through hole 113 through the first bearing 61, and the second end 64 penetrates through the first through hole 21 and is arranged in the second through hole 32 through the second bearing 63. Wherein the second bearing 63 is partially located in the first through hole 21, and the other part is located in the second through hole 32. The connecting piece 7 is arranged on the outer sides of the rack 1 and the mounting plate 3 to fixedly connect the rack 1 and the mounting plate 3, and the connecting piece 7 is provided with a groove 71 avoiding the middle plate 2.

When the power assembly 5 drives the middle plate 2 to rotate, the middle plate 2 rotates around the rotating shaft 6 through the second bearing 63, and the frame 1 and the mounting plate 3 are relatively fixed through the connecting piece 7 and do not rotate along with the middle plate 2. Therefore, the middle plate 2 rotates to drive the follow-up portion 42 to slide in the sliding groove 20, and due to the fact that the distances between different positions of the sliding groove 20 and the rotating center of the middle plate 2 are different, the follow-up portion 42 gradually moves towards the center along the sliding groove 20, drives the clamping main body 41 and the clamping knife 43 to move towards the center along the guide groove 30, and then clamps and presses the product.

As shown in fig. 5, the rotating shaft 6 further has a first key groove 65, and the first through hole 21 of the intermediate plate 2 has a second key groove 22 corresponding to the first key groove 65. When the rotating shaft 6 is inserted into the first through hole 21, the first key groove 65 and the second key groove 22 are aligned and communicated up and down, and a key 650 is provided therein, so that when the middle plate 2 rotates, the rotating shaft 6 rotates synchronously, and the rack 1 and the mounting plate 3 located at the upper and lower sides of the middle plate 2 are fixed by the connecting member 7. Further, the guide slot 30 on the mounting plate 3 is also stationary, thereby providing guidance as the crimping assembly 4 is crimped along the chute 20. The first bearing 61 and the second bearing 63 are used for supporting the rotating body, reducing the resistance of the intermediate plate 2 and the rotating shaft 6 during rotation, and improving the accuracy of rotation.

The clamping end 431 extends above the first and second through

holes

21 and 32 to clamp the product in the through holes. The product may be a wire rod, and extends from one side of the frame 1 to the clamping end 431 through the third through hole 113, the rotating shaft 6, the first through hole 21 and the second through hole 32, so that the product is located in the clamping range of the clamping knife 43.

As shown in fig. 1, the power assembly 5 may include a driving unit 51 and a transmission unit 52. The transmission unit 52 is movably connected with the middle plate 2 and is driven by the driving unit 51 to drive the middle plate 2 to rotate.

As shown in fig. 1 and 2, in the present embodiment, the intermediate plate 2 has a boss 23 protruding outward from the ring-shaped body, i.e., the outer shape of the intermediate plate 2 is similar to a cam. The boss 23 has an elliptical ring-shaped structure. The transmission unit 52 includes a roller 522, and the roller 522 is inserted into the annular hole of the boss 23, linearly reciprocates by the transmission unit 52, and slides in the annular hole of the boss 23, thereby rotating the intermediate plate 2. Wherein, the width of the annular hole of the boss 23 is slightly larger than the diameter (or width) of the roller 522 so as to form clearance fit, and the moving direction of the roller 522 is not parallel to the extending direction of the boss 23.

As shown in fig. 1 and fig. 2, the transmission unit 52 may further include a transmission screw 521, and the transmission screw 521 is movably disposed on the frame 1 and is in transmission connection with the driving unit 51. The roller 522 is fixedly attached (e.g., fastened) to the drive screw 521. Thereby, the driving screw 521 moves linearly by the driving of the driving unit 51 to move the roller 522.

As shown in fig. 6, the drive screw 521 includes a linear member 5211 and a rotary member 5212. The linear member 5211 can be a threaded rod or other rod member with threads on the outer surface, the rotating member 5212 can be similar to a sleeve with internal threads on the inner sidewall, and the rotating member 5212 can be placed over the linear member 5211 such that the internal and external threads engage one another. Wherein the threads are not shown in fig. 5. It is easily understood that the linear member 5211 and the rotational member 5212 can be converted into a linear motion and a rotational motion. The linear member 5211 is also in transmission connection with the driving unit 51, so that the rotating member 5212 can be driven by the driving unit 51 to reciprocate.

In an alternative implementation, as shown in fig. 6, the frame 1 has a first boss 122 and a second boss 123, one end of the linear member 5211 of the driving screw 521 is rotatably disposed (e.g., via a bearing) on the first boss 122, and the other end is rotatably disposed (e.g., via a bearing) on the second boss 123. The first boss 122 and the second boss 123 limit (by bearings) the planar motion of the linear member 5211, so that the driving screw 521 can only perform a rotational motion, more specifically, only a rotational motion rotating along its own axis. Since the rotary member 5212 is threadedly coupled to the linear member 5211, rotation of the linear member 5211 can drive the linear reciprocating movement of the rotary member 5212. The roller 522 is fixedly disposed on the rotating member 5212, so that the roller 522 linearly reciprocates along with the rotating member 5212, thereby driving the intermediate plate 2 to rotate.

The driving unit 51 may be provided as a motor to which one end of the linear member 5211 is connected and driven to rotate by the motor.

Preferably, as shown in fig. 1, the crimping device may further include a coupler 53, and the coupler 53 is in transmission connection with an output shaft of the motor and the linear member 5211 of the transmission screw 521. Thus, rotation of the output shaft of the motor can drive the linear member 5211 to rotate, and further drive the rotary member 5212 to move linearly. The coupling 53 is used for driving and connecting the output shaft of the motor and the linear member 5211, and can provide overload protection for the rotation of the output shaft and the linear member, so that structural damage caused by over-high rotation speed is avoided, and the effect of stabilizing a connecting structure is achieved.

The crimping device may further comprise a guide 121, and the guide 121 is used for guiding the rotation direction of the middle plate 2 in connection with the power assembly 5. For example, as shown in fig. 1 and 6, the guide device 121 may be a slide rail fixedly disposed on the frame 1, the slide rail extends in the same direction as the linear member 5211, a follower plate 1211 is slidably connected to the guide device 121, the other end of the follower plate 1211 is connected to the rotary member 5212, and the roller 522 is also disposed on the follower plate 1211. Thereby, the linear movement of the rotary member 5212 causes the follower plate 1211 to simultaneously move linearly along the linear member 5211 and the guide 121, so that the rollers 522 thereon rotate the intermediate plate 2. Wherein, the follower plate 1211 is provided to connect the rotary member 5212, the roller 522 and the guide 121, respectively, so that the rotary member 5212, the roller 522 and the guide 121 are moved in synchronization, whereby the guide 121 can guide the movement of the rotary member 5212 and the roller 522, and thus the rotation of the intermediate plate 2.

As shown in fig. 1, 2 and 6, the rack 1 may include a first rack 11 and a second rack 12. Wherein, the intermediate plate 2 and the mounting plate 3 are both positioned on the first frame 1, and the power assembly 5 is positioned on the second frame 12. The rotation shaft 6, the first bearing 61, the second bearing 63 and the connecting block 7 are correspondingly located on the first frame 11. The guide 121, the first boss 122 and the second boss 123 are located on the second frame 12. Therefore, the actuating mechanism and the driving mechanism of the clamping and pressing device are respectively positioned on the two racks, and the clamping and pressing device is more convenient to mount, debug or maintain and the like.

With reference to the arrow direction shown in fig. 1, the clamping device of this embodiment drives the transmission screw 521 to move through the driving unit 51, so as to drive the follower plate 1211 and the roller 522 thereon to linearly move under the guidance of the guiding device 121, and the roller 522 drives the middle plate 2 to rotate through the wheel protrusion 23, so that the follower portions 42 of the plurality of clamping assemblies 4 respectively slide along the respective sliding slots 20, and drive the respective clamping main bodies 41 and the clamping knives 43 to move along the guiding slots 30, thereby clamping the product through the plurality of clamping ends 41.

One of the products that can be applied to the crimping device of this embodiment is to crimp a wire rod at an interface of a data line, for example, a data line for charging a mobile phone. As shown in fig. 7, the plug of the data line has a circuit board 91 therein, and the wire 92 is electrically connected to the circuit board 91, so that when the wire 92 is led into the plug from the outside through a wire, the position of the interface 8 between the wire and the plug is usually fastened with an iron shell or a plastic shell, etc. so that the wire and the plug are connected. The iron shell or the plastic shell needs to be clamped and wrapped around the outer contour of the lead to form a tight connection with the plug. The data line is clamped by using the clamping device of this embodiment, the conducting wire sequentially passes through the third through hole 113, the rotating shaft 6, the first through hole 21 and the second through hole 32, and the interface 8 is located at the clamping preset position of the clamping component 4, so that the interface 8 can be clamped by using the clamping device.
