[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] like Figures 1 to 3 As shown, an embodiment of the present invention provides a clamping device, which includes a base 10, a support portion 20, and a clamping portion 30. The support portion 20 is movably disposed on the base 10 and has a support surface 201 for supporting a workpiece to be clamped. The clamping portion 30 has a connecting end 301 and a clamping end 302 disposed opposite each other. The connecting end 301 is movably disposed on the base 10. The moving direction of the connecting end 301 is the same as that of the support portion 20. At least a portion of the clamping end 302 is located above a portion of the supporting surface 201. The height distance of the clamping end 302 relative to the supporting surface 201 is adjustable.

[0036] When applying the technical solution of the present invention, the clamping device needs to be used in conjunction with other devices during the process of an automated production line. During the production process, it may be necessary to clamp the workpiece at different workstations, or to clamp workpieces of different sizes. The support portion 20 and the clamping portion 30 of the device can both be moved relative to the base 10, and the movement direction of the support portion 20 and the clamping portion 30 are the same. This arrangement allows the device to adapt to the needs of different workstations and effectively clamp workpieces of different sizes, allowing the same production line to process multiple products, thereby improving the flexibility and adaptability of the device.

[0037] Taking the end of the copper braided wire flexible connector as an example, the end crimping portion of the copper braided wire flexible connector usually needs to be processed with a device connection hole and the end face is milled flat. When processing the device connection hole and milling the end face, the end of the copper braided wire flexible connector is usually positioned by a clamping device. In the process of an automated production line, when milling copper braided flexible connectors of different specifications, it may be necessary to adjust the relative position between the clamping device and the milling device to ensure the continuity of the milling operation. At this time, according to the position of the milling device, the position of the support part 20 and the clamping part 30 relative to the base body 10 can be directly adjusted, which is more flexible and convenient.

[0038] In the embodiment of this solution, the support portion 20 is movably disposed on the top of the base 10, and the support surface 201 is located on the top surface of the support portion 20. When a workpiece to be clamped is placed on the support surface 201, the clamping end 302 clamps the workpiece so that the support portion 20 and the base 10 do not move, and the position of the clamping portion 30 and the base 10 does not move.

[0039] Furthermore, a first guide groove 51 is provided on the top surface of the base 10, extending in the same direction as the movement direction of the support portion 20. The support portion 20 is a plate-shaped structure, and a first guide portion 52 is provided on the bottom of the support portion 20. The first guide portion 52 is movably disposed within the first guide groove 51 and cooperates with the first guide groove 51 for guidance. This arrangement improves the smoothness of the movement of the support portion 20 relative to the base 10 and makes it easier for the operator to adjust the position of the support portion 20 relative to the base 10.

[0040] In the embodiment of this solution, the first guide groove 51 is provided through the seat body 10 along the length direction of the seat body 10. The cross-sectional shape of the first guide groove 51 is the same as the cross-sectional shape of the first guide portion 52. This arrangement facilitates the insertion of the first guide portion 52 into the first guide groove 51.

[0041] Furthermore, the cross-sectional dimension of the bottom of the first guide groove 51 is larger than the cross-sectional dimension of the top of the first guide groove 51. This configuration can prevent the first guide portion 52 from sliding out of the first guide groove 51.

[0042] The cross-sectional shape of the first guide groove 51 can be set to an inverted trapezoid, an inverted T-shape, or the first guide groove 51 can be set to a dovetail groove or a wedge-shaped groove.

[0043] Furthermore, in order to improve the stability of the support part 20, the device may also include a first fastener 21, which is arranged between the base 10 and the support part 20. When the support part 20 is adjusted into place, the support part 20 and the base 10 are fixed by the first fastener 21.

[0044] The present solution does not limit the specific form of the first fastener 21, wherein the first fastener 21 can be set as a first fastening bolt, which passes through the support portion 20 and abuts against the top surface of the base body 10. The first fastening bolt is threadedly connected to the support portion 20.

[0045] Specifically, the clamping portion 30 includes a mounting seat 31, a driving portion 32, and a clamping plate 33. The mounting seat 31 is movably disposed on a side wall of the base 10, with the mounting seat 31 forming a connection end 301. The driving portion 32 is disposed on the side wall of the mounting seat 31 away from the base 10. The clamping plate 33 is parallel to the support surface 201, with at least a portion of the clamping plate 33 located above a portion of the support surface 201. The clamping plate 33 forms a clamping end 302, and the driving portion 32 is drivingly connected to the clamping plate 33 to adjust the distance between the clamping plate 33 and the support surface 201. This arrangement allows the mounting seat 31 and the driving portion 32 to be located separately on the side of the base 10. As long as the clamping plate 33 is located above the support surface 201, the mounting seat 31 is prevented from occupying the top space of the base 10, thereby optimizing space utilization and avoiding or reducing the possibility of interference between the mounting seat 31 and the workpiece to be clamped, thereby facilitating the clamping operation of the workpiece.

[0046] In this embodiment, a second guide groove 61 is provided on the sidewall of the base 10. The second guide groove 61 extends in the same direction as the movement of the connecting end 301. A second guide portion 62 is provided on the connecting end 301. The second guide portion 62 is movably disposed within and engages with the second guide groove 61. Specifically, the second guide portion 62 is provided on the side of the mounting base 31 closest to the base 10. This arrangement improves the stability and smoothness of the movement of the mounting base 31 relative to the base 10.

[0047] Furthermore, the second guide groove 61 is provided through the base body 10 along the length direction of the base body 10 . This arrangement facilitates the insertion of the second guide portion 62 into the second guide groove 61 .

[0048] Furthermore, the cross-sectional dimension of the bottom of the second guide groove 61 is larger than the cross-sectional dimension of the notch of the second guide groove 61. This arrangement can prevent the second guide portion 62 from sliding out of the second guide groove 61.

[0049] The cross-section of the second guide groove 61 can be in a trapezoidal or T-shaped shape, or the second guide groove 61 can be in a dovetail groove or a wedge-shaped groove.

[0050] Furthermore, in order to improve the stability of the mounting seat 31, the device may also include a second fastener 311, which is arranged between the base 10 and the mounting seat 31. When the mounting seat 31 is adjusted into place, the mounting seat 31 and the base 10 are fixed by the second fastener 311.

[0051] The present invention does not limit the specific form of the second fastener 311, wherein the second fastener 311 can be set as a first fastening bolt, which passes through the mounting seat 31 and abuts against the side wall of the seat body 10. The first fastening bolt is threadedly connected to the mounting seat 31.

[0052] This solution does not limit the specific form of the driving part 32, wherein it can be in the form of a motor, a screw, and a nut that cooperate with each other, or it can be in the form of a motor, a gear, and a rack that cooperate with each other.

[0053] In an embodiment of the present solution, the driving portion 32 includes a driving cylinder, the cylinder seat of the driving cylinder is arranged on the side wall of the mounting base 31 on the side away from the base body 10, and the piston rod of the driving cylinder is located above the cylinder seat and extends and retracts in the vertical direction. The driving cylinder has a lifting air path inlet and a descending air path inlet, and the clamping device also includes a reversing valve 40, a first connecting pipe 41 and a second connecting pipe 42. Among them, one end of the first connecting pipe 41 is connected to the reversing valve 40, and the other end is connected to the lifting air path inlet; one end of the second connecting pipe 42 is connected to the reversing valve 40, and the other end is connected to the descending air path inlet. This solution controls the connecting pipe status of the first connecting pipe 41 and the second connecting pipe 42 by the reversing valve 40, thereby realizing the switching of the lifting and descending actions of the driving cylinder, thereby simplifying the operation process.

[0054] In some embodiments of the present solution, the base body 10 is provided with an installation cavity 101 , one end of a portion of the first connecting tube 41 is located outside the base body 10 , and a portion of the first connecting tube 41 is located inside the installation cavity 101 .

[0055] In some embodiments of the present solution, part of the second connecting tube 42 is located outside the base body 10 , and part of the second connecting tube 42 is located inside the installation cavity 101 .

[0056] In the embodiment of this solution, one end of a portion of the first connecting tube 41 is located outside the base 10, while another portion of the first connecting tube 41 is located within the mounting cavity 101. Furthermore, a portion of the second connecting tube 42 is located outside the base 10, while another portion of the second connecting tube 42 is located within the mounting cavity 101. This arrangement reduces the exposed length of the first and second connecting tubes 41, 42, reducing the risk of impact, abrasion, and the like. Furthermore, this arrangement allows the mounting cavity 101 to function as a storage chamber, enhancing the compactness of the structure.

[0057] Furthermore, a threading hole 102 is provided on the side wall of the base body 10, and the threading hole 102 is connected to the installation cavity 101. The first connecting tube 41 is passed through the threading hole 102, and the second connecting tube 42 is passed through the threading hole 102. It can be understood that the provision of the threading hole 102 can improve the smoothness of the first connecting tube 41 and the second connecting tube 42 passing from the outside of the base body 10 into the installation cavity 101.

[0058] In this solution, the first connecting tube 41 and the second connecting tube 42 may share a threading hole 102 , or may be respectively provided with a threading hole 102 .

[0059] Furthermore, a threading hole 102 is provided on the side wall of the base 10 where the mounting seat 31 is located. This arrangement minimizes the distance between the threading hole 102 and the driving cylinder, and minimizes the length of the first connecting tube 41 and the second connecting tube 42, further improving the structural compactness and rationality of the device. Furthermore, this arrangement can reduce interference with other components caused by the excessive length of the first connecting tube 41 and the second connecting tube 42.

[0060] In some embodiments of this solution, the length direction of the base body 10 is the same as the movement direction of the support portion 20. In some embodiments of this solution, the installation cavity 101 has an opening, which is located at one end of the length direction of the base body 10, and the reversing valve 40 is located at the opening of the installation cavity 101. This arrangement facilitates the assembly of the reversing valve 40, the first connecting pipe 41, and the second connecting pipe 42.

[0061] Furthermore, two sets of clamping parts 30 are provided, one on either side of the support portion 20 in its direction of movement, with a gap between the clamping ends 302 of the two sets. This arrangement provides a more stable clamping of the workpiece, reducing vibration or deviation during machining and improving the stability of the workpiece clamping. Furthermore, when other devices, such as a milling cutter or drilling device, are required to process the surface of the clamped workpiece, this arrangement ensures smooth operation of the milling cutter or drilling device.

[0062] In this embodiment, the supporting portion 20 and the two sets of clamping portions 30 cooperate with each other to form a clamping module, and multiple sets of clamping modules are provided along the moving direction of the supporting portion 20. This arrangement can further enhance the adaptability of the device, enabling the device to clamp multiple workpieces or multiple parts of a workpiece.

[0063] In the embodiment of this solution, two groups of clamping modules are provided.

[0064] Specifically, the base body 10 of the present device is generally in the shape of a cubic shell, and both ends of the base body 10 in the longitudinal direction are open. The base body 10 specifically includes a bottom plate 11, a first side plate 121, a second side plate 122 and a top plate 13. Among them, the support part 20 is movably arranged on the top surface of the top plate 13. In a group of clamping modules, the mounting seat 31 of one clamping part 30 is movably arranged on the outer wall of the first side plate 121, and the mounting seat 31 of the other clamping part 30 is movably arranged on the outer wall of the second side plate 122. A threading hole 102 is provided on the first side plate 121, and the two clamping parts 30 on the first side plate 121 are respectively located on both sides of the threading hole 102; a threading hole 102 is provided on the second side plate 122, and the two driving cylinders on the second side plate 122 are respectively located on both sides of the threading hole 102.

[0065] In this embodiment, the four driving cylinders share a single first connecting pipe 41. The first connecting pipe 41 includes a first main pipe and two first branch pipes. One end of the first main pipe is connected to the reversing valve 40, and the other end extends into the mounting cavity 101. One end of each of the two first branch pipes is connected to the first main pipe. One of the first branch pipes passes through the threading hole 102 on the first side plate 121 and is located outside the first side plate 121. The other first branch pipe passes through the threading hole 102 on the second side plate 122 and is located outside the second side plate 122. The two driving cylinders located on the same side of the base 10 share the single first branch pipe. The device of this embodiment also includes a first three-way pipe 411, located on the outside of the base 10 near the two driving cylinders. The first end of the first three-way pipe 411 is connected to the first branch pipe, the second end of the first three-way pipe 411 is connected to the lifting air inlet of one of the driving cylinders, and the third end of the first three-way pipe 411 is connected to the lifting air inlet of the other driving cylinder. Such an arrangement can reduce the number of first branch pipes used as much as possible and improve the structural compactness of the device.

[0066] Furthermore, a valve is provided on the second end and the third end of the first three-way pipe 411. Such a configuration enables one of the two driving cylinders located outside the first side plate 121 to operate normally when one of the driving cylinders is damaged.

[0067] Furthermore, in this embodiment, the four driving cylinders share a single second connecting pipe 42. The second connecting pipe 42 comprises a second main pipe and two second branch pipes. One end of the second main pipe is connected to the reversing valve 40, and the other end extends into the mounting cavity 101. One end of each of the two second branch pipes is connected to the second main pipe. One end of one of the second branch pipes passes through a threading hole in the first side plate 121 and is located outside the first side plate 121, while the other second branch pipe passes through a threading hole 102 in the second side plate 122 and is located outside the second side plate 122. The two driving cylinders located on the same side of the base 10 share the single second branch pipe. The device of this embodiment also includes a second three-way pipe 421, which is located on the outside of the base 10 near the two driving cylinders. The first end of the second three-way pipe 421 is connected to the second branch pipe, the second end of the second three-way pipe 421 is connected to the descending air inlet of one of the driving cylinders, and the third end of the second three-way pipe 421 is connected to the descending air inlet of the other driving cylinder. Such an arrangement can reduce the number of second connecting pipes 42 used as much as possible, thereby improving the structural compactness of the device.

[0068] Furthermore, a valve is provided on the second end and the third end of the second three-way pipe 421. Such a configuration enables one of the two driving cylinders located outside the second side plate 122 to operate normally when one of the driving cylinders is damaged.

[0069] Furthermore, a support groove 2011 is provided at the top of the support portion 20. The bottom of the support groove 2011 forms a support surface 201. At least one end of the support groove 2011 is open along the movement direction of the support portion 20. This arrangement facilitates placement of a workpiece to be clamped within the support groove 2011.

[0070] When two groups of clamping modules are provided, the ends of the two support slots 2011 that are close to each other are open and the other ends are blocked; alternatively, when two groups of clamping modules are provided, the ends of the two support slots 2011 that are close to each other are blocked and the other ends are open. The blocking structure can serve as a stop and position for the workpiece to be clamped, further improving the stability of the workpiece during the clamping process.

[0071] In the embodiment of the present scheme, when two groups of clamping modules are provided, both ends of the support groove 2011 are open structures. And along the moving direction of the support portion 20, the mounting cavity 101 is provided through the seat body 10, that is, the mounting cavity 101 has two openings, and the reversing valve 40 is located at one opening of the mounting cavity 101. Such an arrangement makes the layout of the reversing valve 40 more flexible and convenient for daily inspection and maintenance. When the workpiece to be clamped is a flexible workpiece with a long length, and only one end of the workpiece needs to be clamped, the other end of the workpiece to be clamped can be accommodated in the mounting cavity 101. When the workpiece to be clamped is a flexible workpiece with a long length, and both ends of the workpiece need to be clamped, the main body of the flexible workpiece can be passed through the mounting cavity 101, and the two ends of the workpiece are respectively bent outward from the two ends of the mounting cavity 101 and respectively extend into the support groove 2011. Such an arrangement can effectively utilize space and reduce the possibility of the workpiece swinging on the production line or interfering with other processes.
