The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] The following is for reference. Figure 1 Describes a clamping device 100 according to an embodiment of the present invention.

[0028] like Figure 1 As shown, the clamping device 100 according to an embodiment of the present utility model includes: a mounting base 10, a driving member 20, a connecting structure 30, and a plurality of clamping members 40.

[0029] The clamping device 100 is used to clamp the part to be clamped. The driving member 20 is provided on the mounting base 10 and includes a driving body 21 and a driving part 22 connected together. The connecting structure 30 is connected to the driving part 22. Multiple clamping members 40 are rotatably provided on the mounting base 10 and each has a connecting part 41 and a clamping part 42. The multiple connecting parts 41 are rotatably connected to the connecting structure 30. The driving body 21 can drive the driving part 22 to drive the connecting structure 30 to move, so that the ends of the multiple clamping parts 42 away from the corresponding connecting parts 41 move relatively closer or relatively farther away to clamp the part to be clamped.

[0030] The clamping device 100 is used to clamp the part to be clamped. As some embodiments of this application, the driving device is connected to the mounting base 10 of the clamping device 100. The driving device can drive the clamping device 100 to move so as to change the position of the clamping device 100.

[0031] For example, the drive device can drive the clamping device 100 above the conveyor belt, the clamping device 100 can clamp the forging located on the conveyor belt, after the clamping device 100 clamps the forging located on the conveyor belt, the drive device can drive the clamping device 100 to the straightening machine, the clamping device 100 can release the forging to place the forging on the straightening machine, and the clamping device 100 can clamp the forging located on the straightening machine, after the clamping device 100 clamps the forging located on the straightening machine, the drive device can drive the clamping device 100 to the temperature-controlled cooling conveyor belt, the clamping device 100 can release the forging to place the forging on the temperature-controlled cooling conveyor belt.

[0032] The driving component 20 is disposed on the mounting base 10 and connected to the mounting base 10. The connection method between the driving component 20 and the mounting base 10 can be, but is not limited to, snap-fit ​​or bolt connection. As some embodiments of this application, the driving component 20 and the mounting base 10 are connected by bolt connection. The driving component 20 includes a connected driving body 21 and a driving part 22, which are connected and the driving body 21 can drive the driving part 22 to move. As some embodiments of this application, the driving component 20 can be constructed as a cylinder, or as a linear motor. As some embodiments of this application, the driving body 21 can move along a first direction (i.e., Figure 1 The drive unit 22 is driven to move (e.g., the drive unit 22 is moved) in the X direction shown.

[0033] The connecting structure 30 is connected to the driving part 22. The connection method between the connecting structure 30 and the driving part 22 can be, but is not limited to, welding, bolt connection, etc. As some embodiments of this application, the connecting structure 30 and the driving part 22 are connected by bolt connection.

[0034] The clamping device 100 includes a plurality of clamping elements 40, the number of which may be, but is not limited to, two, three, four, etc. As some embodiments of this application, the number of clamping elements 40 is two. The plurality of clamping elements 40 are rotatably disposed on the mounting base 10. As some embodiments of this application, the clamping element 40 may have one of a pivot hole and a pivot shaft, and the mounting base 10 may have the other of a pivot hole and a pivot shaft. For example, the clamping element 40 may have a pivot hole, and the mounting base 10 may have a pivot shaft; or, the clamping element 40 may have a pivot shaft, and the mounting base 10 may have a pivot hole. By engaging the pivot hole and the pivot shaft, the clamping element 40 and the mounting base 10 can be rotatably connected.

[0035] Alternatively, both the gripper 40 and the mounting base 10 have pivot holes, and the pivot holes of the gripper 40 and the mounting base 10 are connected by a pivot shaft. For example, the pivot shaft passes through the pivot hole of the gripper 40 and the pivot hole of the mounting base 10, and by engaging the pivot hole and the pivot shaft, the gripper 40 and the mounting base 10 can be rotatably connected.

[0036] Each of the multiple clamping parts 40 includes a connecting portion 41 and a clamping portion 42. In some embodiments of this application, the surface of the clamping portion 42 is knurled. Knurling increases the friction between the clamping portion 42 and the workpiece to be clamped, reducing the probability of the workpiece falling during clamping and improving the clamping stability of the clamping device 100. In some embodiments of this application, the connecting portion 41 and the clamping portion 42 can be separate parts, or they can be integrally formed.

[0037] Multiple connecting portions 41 of the multiple clamping members 40 are rotatably connected to the connecting structure 30. As some embodiments of this application, the connecting portion 41 may have one of a pivot hole and a pivot shaft, and the connecting structure 30 may have the other of a pivot hole and a pivot shaft. Alternatively, both the connecting portion 41 and the connecting structure 30 may have pivot holes, and the pivot holes of the connecting portion 41 and the mounting base 10 may be connected by pivot shafts. By making the pivot holes and pivot shafts cooperate with each other, the connecting portion 41 and the connecting structure 30 can be rotatably connected.

[0038] The driving body 21 can drive the driving part 22 to move. When the driving part 22 moves, it can drive (or can be understood as driving) the connecting structure 30 to move, so that the ends of the multiple gripping parts 42 away from the corresponding connecting parts 41 move relatively closer or relatively farther away, so as to grip the object to be gripped. As some embodiments of this application, the driving body 21 can drive the driving part 22 along a first direction (i.e. Figure 1 The drive unit 22 moves along the first direction (i.e., the X direction shown) and moves along the first direction (i.e., the X direction shown). Figure 1 The movement of the connecting structure 30 in the X direction (as shown) can drive the connecting structure 30 along the first direction (i.e., Figure 1 The connecting structure 30 moves in the X direction (as shown), and the connecting part 41 of the connecting structure 30 and the clamping member 40 is rotatably connected. The connecting structure 30 moves along the first direction (i.e., Figure 1 The X-direction movement shown can cause the ends of the multiple gripping parts 42 that are away from the corresponding connecting parts 41 to move relatively closer or relatively farther away.

[0039] As some embodiments of this application, when the plurality of gripping parts 42 move relatively close together, they can grip the object to be gripped; when the plurality of gripping parts 42 move relatively far apart, they can release the object to be gripped. Alternatively, when the plurality of gripping parts 42 move relatively close together, they can release the object to be gripped; when the plurality of gripping parts 42 move relatively far apart, they can grip the object to be gripped.

[0040] Therefore, the clamping device 100 of this application can complete the clamping of the workpiece under the drive of a single drive member 20, which can effectively reduce the weight of the clamping device 100 and reduce the probability of motion imbalance and abnormal vibration of the clamping device 100 during rapid operation, thereby speeding up the operation and improving the production cycle. Furthermore, since the single drive member 20 does not have the problem of inconsistent action, it can reliably clamp the workpiece, which is beneficial to improving the clamping stability and reliability of the clamping device 100.

[0041] In some embodiments of this utility model, such as Figure 1 As shown, the clamping device 100 further includes a plurality of first pins 51, which are respectively fitted and assembled with corresponding connecting parts 41 and mounting bases 10 so that the plurality of clamping parts 40 can be rotatably mounted on the mounting base 10.

[0042] The clamping device 100 further includes a plurality of first pins 51, the number of which is the same as the number of clamping members 40 and they are arranged in a one-to-one correspondence. The plurality of first pins 51 are respectively assembled with corresponding connecting parts 41 and mounting bases 10. Specifically, each clamping member 40 has a connecting part 41, and the first pins 51 can be assembled with the connecting parts 41 of the corresponding clamping member 40. In addition, the plurality of first pins 51 can be assembled with the mounting base 10 so that the plurality of clamping members 40 can be rotatably connected to the mounting base 10.

[0043] As some embodiments of this application, the first pin 51 is fixedly connected to the corresponding connecting part 41. The first pin 51 can serve as the pivot shaft of the corresponding connecting part 41. The mounting base 10 has a pivot hole that mates with the first pin 51. By mates the pivot hole and the pivot shaft with each other, multiple clamping parts 40 can be rotatably connected to the mounting base 10.

[0044] As some embodiments of this application, the first pin 51 is fixedly connected to the mounting base 10. The first pin 51 can serve as the pivot shaft of the corresponding connecting part 41. The connecting part 41 has a pivot hole that mates with the first pin 51. By mates the pivot hole and the pivot shaft with each other, multiple clamping parts 40 can be rotatably connected to the mounting base 10.

[0045] By assembling multiple first pins 51 with corresponding connecting parts 41 and mounting bases 10, multiple clamping parts 40 can be rotatably mounted on the mounting base 10, ensuring reliable connection between the clamping parts 40 and the mounting base 10. Furthermore, this arrangement allows for a certain distance between the part to be clamped and the driving part 20, reducing the impact of the heat from the part to be clamped on the driving part 20 and thus lowering the probability of damage to the driving part 20.

[0046] In some embodiments of this utility model, such as Figure 1 As shown, the connecting part 41 has a first mating hole 61, and the first pin 51 passes through the corresponding first mating hole 61 and is fixed to the mounting base 10.

[0047] Each of the multiple connecting parts 41 includes a first mating hole 61, and the first pin 51 passes through the first mating hole 61 of the corresponding connecting part 41. That is, the first pin 51 mates with the shaft hole of the first mating hole 61 of the corresponding connecting part 41, and the first pin 51 is fixedly connected to the mounting base 10. The fixed connection between the first pin 51 and the mounting base 10 can be, but is not limited to, welding, bolt connection, etc.

[0048] By having the connecting part 41 have a first mating hole 61, and by having the first pin 51 pass through the corresponding first mating hole 61 and be fixed to the mounting base 10, the clamping member 40 can rotate around the first pin 51 as the rotation axis. Furthermore, the connection between the clamping member 40 and the mounting base 10 can be made secure. Moreover, this arrangement facilitates the assembly of the clamping device 100 and reduces the assembly difficulty of the clamping device 100.

[0049] In some embodiments of this utility model, such as Figure 1 As shown, the clamping device 100 also includes a plurality of connectors 31, which are rotatably connected to the connecting structure 30 and the corresponding connecting part 41.

[0050] The clamping device 100 also includes a connector 31. The number of connectors 31 can be multiple, including but not limited to two, three, four, etc. The number of connectors 31 is the same as the number of clamping members 40 and they are set in a one-to-one correspondence. As some embodiments of this application, there are two connectors 31 and two clamping members 40, and the two connectors 31 and the two clamping members 40 are set in a one-to-one correspondence.

[0051] Multiple connectors 31 are rotatably connected to the connecting structure 30. Specifically, each connector 31 may have one of a pivot hole and a pivot shaft, and the connecting structure 30 may have the other of a pivot hole and a pivot shaft. For example, the connector 31 may have a pivot hole, and the connecting structure 30 may have a pivot shaft; or, the connector 31 may have a pivot shaft, and the connecting structure 30 may have a pivot hole. By engaging the pivot hole and the pivot shaft, the connector 31 and the connecting structure 30 can be rotatably connected. Alternatively, both the connector 31 and the connecting structure 30 may have pivot holes, and the pivot holes of the connector 31 and the connecting structure 30 are connected by pivot shafts. By engaging the pivot hole and the pivot shaft, the connector 31 and the connecting structure 30 can be rotatably connected.

[0052] The connector 31 is also rotatably connected to the corresponding connector 41. Specifically, the connector 31 may have one of a pivot hole and a pivot shaft, and the corresponding connector 41 may have the other of a pivot hole and a pivot shaft. For example, the connector 31 may have a pivot hole and the corresponding connector 41 may have a pivot shaft, or the connector 31 may have a pivot shaft and the corresponding connector 41 may have a pivot hole. By making the pivot hole and the pivot shaft cooperate with each other, multiple connectors 31 can be rotatably connected to the corresponding connector 41 respectively.

[0053] Alternatively, both the connector 31 and the corresponding connecting part 41 have pivot holes, and the pivot holes of the connector 31 and the corresponding connecting parts 41 are connected by pivot shafts (for example, the pivot shaft passes through the pivot holes of the connector 31 and the corresponding connecting parts 41). By making the pivot holes and pivot shafts cooperate with each other, multiple connectors 31 can be rotatably connected to the corresponding connecting parts 41 respectively.

[0054] By including multiple connectors 31 in the clamping device 100, and making the multiple connectors 31 rotatably connected to the connecting structure 30 and the corresponding connecting part 41, the operation of the clamping device 100 can be made smooth, thereby improving the clamping stability of the clamping device 100. Furthermore, by providing connectors 31, the distance between the part to be clamped and the driving member 20 can be made greater, thereby further reducing the impact of the heat of the part to be clamped on the driving member 20.

[0055] In some embodiments of this utility model, such as Figure 1 As shown, the clamping device 100 further includes a plurality of second pins 52, which are respectively fitted with corresponding connectors 31 and connecting structures 30 to make the connectors 31 and connecting structures 30 rotatably connected.

[0056] The clamping device 100 further includes a plurality of second pins 52, the number of which is the same as the number of connecting members 31 and they are arranged in a one-to-one correspondence. The plurality of second pins 52 are respectively assembled with the corresponding connecting members 31 and connecting structures 30. Specifically, the plurality of second pins 52 can be assembled with the corresponding plurality of connecting members 31, and the plurality of second pins 52 can also be assembled with the connecting structures 30, so that the plurality of connecting members 31 can be rotatably connected to the connecting structures 30.

[0057] As some embodiments of this application, the second pin 52 is fixedly connected to the corresponding connector 31. The second pin 52 can serve as the pivot shaft of the corresponding connector 31. The connecting structure 30 has a pivot hole that mates with the second pin 52. By mates the pivot hole and the pivot shaft with each other, multiple connectors 31 can be rotatably connected to the connecting structure 30.

[0058] As some embodiments of this application, the second pin 52 is fixedly connected to the connecting structure 30. The second pin 52 can serve as the pivot shaft of the corresponding connecting member 31. The connecting member 31 has a pivot hole that mates with the second pin 52. By mates the pivot hole and the pivot shaft with each other, multiple connecting members 31 can be rotatably connected to the connecting structure 30.

[0059] By assembling multiple second pins 52 with corresponding connectors 31 and connecting structures 30 respectively, multiple connectors 31 can be rotatably connected to the connecting structure 30, thus ensuring a reliable connection between the connectors 31 and the connecting structure 30.

[0060] In some embodiments of this utility model, such as Figure 1 As shown, the connector 31 has a second mating hole 62, and the second pin 52 passes through the corresponding second mating hole 62 and is fixed to the connecting structure 30.

[0061] The connector 31 includes a second mating hole 62, and the second pin 52 passes through the second mating hole 62 of the corresponding connector 31. That is, the second pin 52 mates with the shaft hole of the second mating hole 62 of the connector 31, and the second pin 52 is fixedly connected to the connecting structure 30. The fixed connection between the second pin 52 and the connecting structure 30 can be, but is not limited to, welding, bolt connection, etc.

[0062] By providing the connector 31 with a second mating hole 62 and having the second pin 52 pass through the corresponding second mating hole 62 and fixed to the connecting structure 30, the connector 31 can rotate around the second pin 52 as a rotation axis. Furthermore, the connection between the connector 31 and the connecting structure 30 can be made reliable. Moreover, this arrangement facilitates the assembly of the clamping device 100 and reduces the assembly difficulty of the clamping device 100.

[0063] In some embodiments of this utility model, such as Figure 1 As shown, the clamping device 100 further includes a plurality of third pins 53, which are respectively fitted with corresponding connectors 31 and corresponding connecting parts 41 so that the connectors 31 and the corresponding connecting parts 41 are rotatably connected.

[0064] The clamping device 100 further includes multiple third pins 53. The number of third pins 53, the number of connectors 31, and the number of connecting parts 41 are the same and correspond one-to-one. Each of the multiple third pins 53 is respectively assembled with a corresponding connector 31 and a corresponding connecting part 41. Specifically, the multiple third pins 53 can be assembled with a corresponding multiple connectors 31, and the multiple third pins 53 can also be assembled with a corresponding connecting part 41, so that each of the multiple connectors 31 can be rotatably connected to the corresponding connecting part 41. It should be noted that the assembly method of the third pins 53 with the corresponding connectors 31 and the corresponding connecting parts 41 is a shaft-hole fit. As some embodiments of this application, the third pins 53 can be fixedly connected to the corresponding connectors 31 or the corresponding connecting parts 41.

[0065] As some embodiments of this application, the third pin 53 is fixedly connected to the corresponding connector 31, and the corresponding connector 41 has a pivot hole that cooperates with the third pin 53. By making the pivot hole and the pivot shaft cooperate with each other, multiple grippers 40 can be rotatably connected to the corresponding connector 41.

[0066] As some embodiments of this application, the third pin 53 is fixedly connected to the corresponding connecting part 41, and the connecting member 31 has a pivot hole that cooperates with the third pin 53. By making the pivot hole and the pivot shaft cooperate with each other, multiple connecting members 31 can be rotatably connected to the connecting part 41 of the corresponding clamping member 40.

[0067] The third pin 53 can be fixedly connected to the connecting part 41 and the connecting piece 31 by means of, but not limited to, welding, bolting, etc.

[0068] By assembling multiple third pins 53 with corresponding connectors 31 and corresponding connecting parts 41 respectively, multiple connectors 31 can be rotatably connected to the corresponding connecting parts 41, thus ensuring reliable connection between the connectors 31 and the corresponding connecting parts 41.

[0069] In some embodiments of this utility model, such as Figure 1 As shown, the mounting base 10 includes a first sub-mounting base 11, which defines a first mounting space 112. The drive body 21 is disposed in the first mounting space 112, and the drive unit 22 passes through the side wall 111 of the first sub-mounting base 11.

[0070] The mounting base 10 includes a first sub-mounting base 11, which defines a first mounting space 112. The driving body 21 of the driving component 20 is disposed in the first mounting space 112, along a first direction (i.e., Figure 1(in the X direction shown), the first mounting space 112 has two opposing sidewalls, wherein the driving part 22 of the driving member 20 can pass through the sidewall 111 near the connecting structure 30 to connect with the connecting structure 30.

[0071] As some embodiments of this application, the first sub-mount 11 has an observation port, the drive member 20 can be configured as a cylinder, and the observation port can correspond to the magnetic switch of the cylinder to facilitate the detection of the drive member 20 or the replacement of the magnetic switch of the cylinder.

[0072] By placing the drive body 21 in the first mounting space 112, the first sub-mount 11 can provide protection for the drive body 21, thereby reducing the probability of the drive body 21 being impacted. Furthermore, by having the first sub-mount 11 have a side wall 111 and having the drive unit 22 pass through the side wall 111 of the first sub-mount 11, the drive body 21 can be separated from the workpiece to be clamped by the side wall 111, thereby reducing the impact of the heat from the workpiece to be clamped on the drive body 21 (for example, reducing the probability of damage to the seals of the drive body 21).

[0073] In some embodiments of this utility model, such as Figure 1 As shown, the mounting base 10 also includes a second sub-mounting base 12, which is connected to the first sub-mounting base 11 and defines a second mounting space 121. The connecting structure 30 and the connecting portion 41 are located in the second mounting space 121, and at least a portion of the clamping portion 42 is located outside the second mounting space 121.

[0074] The mounting base 10 also includes a second sub-mounting base 12, which is connected to the first sub-mounting base 11. In some embodiments of this application, the second sub-mounting base 12 and the first sub-mounting base 11 are separate parts. In some embodiments of this application, the second sub-mounting base 12 and the first sub-mounting base 11 are integrally formed parts, that is, the second sub-mounting base 12 and the first sub-mounting base 11 are integrally formed. The integrally formed parts have high structural strength, and this arrangement can reduce the probability of the second sub-mounting base 12 and the first sub-mounting base 11 separating.

[0075] The second sub-mount 12 can define a second mounting space 121. The connecting structure 30 and the connecting part 41 are both disposed within the second mounting space 121. At least a part of the structure of the clamping part 42 is located outside the second mounting space 121. That is, a part of the structure of the clamping part 42 is located outside the second mounting space 121, or the entire structure of the clamping part 42 is located outside the second mounting space 121.

[0076] By positioning the connecting structure 30 and the connecting portion 41 within the second mounting space 121, and with at least a portion of the clamping portion 42 located outside the second mounting space 121, the connecting structure 30 and the connecting portion 41 can be protected by the second sub-mount 12. Furthermore, the clamping portion 42 can clamp the workpiece to be clamped. Additionally, the second sub-mount 12 can drive the body 21 to be spaced apart from the workpiece to be clamped, thereby further reducing the impact of the heat from the workpiece to be clamped on the drive body 21.

[0077] In some embodiments of this utility model, multiple clamping members 40 are adapted to extend into the interior of the object to be clamped in order to clamp the object.

[0078] When it is necessary to clamp the object to be clamped, multiple clamping parts 40 can penetrate into the interior of the object to be clamped (for example, the object to be clamped is a hollow rod-shaped structure). Then, the ends of multiple clamping parts 42 that are away from the corresponding connecting parts 41 move relatively away to abut against the inner wall of the object to be clamped in order to clamp the object. When it is necessary to release the object to be clamped, the ends of multiple clamping parts 42 that are away from the corresponding connecting parts 41 move relatively closer to each other to separate from the inner wall of the object to be clamped.

[0079] By making the gripping members 40 suitable for extending into the interior of the object to be gripped to grip the object, the gripping device 100 can easily grip the object to be gripped, which can reduce the probability of relative movement between the gripping members 40 and the object to be gripped after the gripping device 100 grips the object to be gripped, and is beneficial to improving the gripping stability of the gripping device 100.
