[0036] Pay-off and take-up equipment is widely used in the field of wire and cable production. When the pay-off and take-up equipment is in use, a clamping device and a clamping mechanism are respectively arranged at both ends of the frame. The turntables are respectively clamped by the clamping device and the clamping mechanism, and the middle of the turntables is resisted. Then, the clamping device or the clamping mechanism is driven to rotate through devices such as a motor belt, so as to drive the turntables to pay off and take up wires. Therefore, the coaxiality requirements for the clamping devices and the clamping mechanisms at both ends of the pay-off and take-up machine are relatively high. Due to the influence of welding thermal stress, it is difficult to achieve by general processing and requires complex debugging and trimming.

[0037] In view of this, the present utility model provides a clamping device 100. By arranging a spherical plain bearing 12 to connect the head 10 and the connecting head 311 of the driving unit 30, it can ensure that the head 10 rotates a certain angle within a certain range, not only retaining a certain self-adaptive performance, but also having relatively low coaxiality requirements for the installation of the clamping device 100 and other clamping mechanisms, and being easy to process and manufacture.

[0038] In order to better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the accompanying drawings.

[0039] As Figures 1-4As shown in the figure, the present utility model provides a clamping device 100, which includes a head 10, a main body 20, and a driving unit 30. One end of the head 10 is provided with a mounting groove 11, and a spherical plain bearing 12 is arranged in the mounting groove 11. An installation cavity 23 is arranged in the main body 20. The driving unit 30 is arranged in the installation cavity 23, and one end of the driving unit 30 extends from one end of the main body 20 and is provided with a connection head 311, and the connection head 311 is inserted into the spherical plain bearing 12. Wherein, the driving unit 30 is driven to enable the head 10 to move axially.

[0040] It can be understood that the main body 20 is used for being fixedly installed on a frame 200 to fixedly install the clamping device 100. An installation cavity 23 is arranged in the main body 20. The driving unit 30 is arranged in the installation cavity 23, and one end of the driving unit 30 extends from one end of the main body 20 and is provided with a connection head 311. The head 10 is used for abutting against components such as a turntable 300. A mounting groove 11 is arranged on the side of the head 10 away from the turntable 300, and a spherical plain bearing 12 is arranged in the mounting groove 11. The connection head 311 is inserted into the spherical plain bearing 12. With such a setting, when installing the clamping device 100, when the clamping device 100 and the clamping mechanism jointly press against the turntable 300, it is ensured that the head 10 can rotate within a certain range, has a certain self - adaptability, and has a lower requirement for the coaxiality of the installation of the clamping device 100 and the clamping mechanism. The driving unit 30 can enable the head 10 to move axially so that the distance between the clamping device 100 and the clamping mechanism is appropriate and the turntable 300 can be clamped.

[0041] Furthermore, in an embodiment of the present utility model, the driving unit 30 includes a telescopic mechanism and a driving mechanism 33. First through - holes 24 and second through - holes 25 are respectively arranged at both ends of the main body 20. The first through - hole 24 and the second through - hole 25 are coaxially arranged with the main body 20 and communicated with the installation cavity 23. One end of the driving mechanism 33 passes through the first through - hole 24 and enters the installation cavity 23. One end of the telescopic mechanism is provided with a connection head 311, and the other end of the telescopic mechanism passes through the second through - hole 25 and enters the installation cavity 23 and is threadedly connected with the driving mechanism 33. The driving mechanism 33 is rotated around the axis to drive the telescopic mechanism to move axially.

[0042] It can be understood that one end of the main body 20 away from the head 10 is provided with a first through hole 24, and one end of the main body 20 close to the head 10 is provided with a second through hole 25. One end of the driving mechanism 33 close to the head 10 penetrates into the installation cavity 23 through the first through hole 24, and one end of the telescopic mechanism away from the head 10 penetrates into the installation cavity 23 through the second through hole 25 and is threadedly connected to the telescopic mechanism. The user can rotate one end of the driving mechanism 33 away from the head 10 to make the driving mechanism 33 rotate around the axis. Since the telescopic mechanism and the driving mechanism 33 are threadedly connected, the rotation of the driving mechanism 33 at this time will drive the telescopic mechanism to move axially, thereby driving the head 10 to move axially, so as to change the distance between the clamping device 100 and the clamping mechanism, and realize the clamping and fixing of the turntable 300.

[0043] Further, in an embodiment of the present invention, the driving mechanism 33 includes a handle 331 and a driving rod 332 connected to the handle 331; one end of the driving rod 332 is arranged in the installation cavity 23 and is threadedly connected to the telescopic mechanism; the other end of the driving rod 332 passes through the first through hole (24) and is connected to the handle 331.

[0044] It can be understood that by providing the handle 331, it is convenient for the user to rotate the driving mechanism 33. When the user rotates the handle 331, the handle 331 will drive the driving rod 332 to rotate around the axis, thereby further driving the telescopic mechanism to move axially.

[0045] Further, in an embodiment of the present invention, the telescopic mechanism includes a driving part 32 and a connecting part 31; a connecting cavity 323 is provided in the driving part 32, and a first through hole 322 and a second through hole 325 are respectively provided at both ends of the driving part 32. The first through hole 322 and the second through hole 325 are coaxially arranged and both communicate with the connecting cavity 323; the hole wall of the first through hole 322 is threadedly connected to the driving rod 332; one end of the connecting part 31 away from the connecting head 311 is further provided with a connecting rod 312. The connecting rod 312 penetrates into the connecting cavity 323 through the second through hole 325, and a holding mechanism 328 is further provided between the outer wall of the connecting rod 312 and the inner wall of the driving part 32.

[0046] It can be understood that a connection cavity 323 is provided inside the driving part 32. A first end cap 321 is provided at one end of the driving part 32 away from the head 10. A through hole is formed in the first end cap 321. A second end cap 324 is provided at one end of the driving part 32 away from the head 10. A second through hole 325 is provided on the second end cap 324. The first through hole 322 and the second through hole 325 are both communicated with the connection cavity 323. The hole wall of the first through hole 322 is threadedly connected to the driving rod 332. With such a setting, when the driving rod 332 rotates, it will drive the first end cap 321 to move axially, and then make the entire driving part 32 move axially. One end of the connecting part 31 away from the connecting head 311 is further provided with a connecting rod 312. The connecting rod 312 passes through the second through hole 325 and enters the connection cavity 323. A holding mechanism 328 is further provided between the outer wall of the connecting rod 312 and the inner wall of the driving part 32. The holding mechanism 328 can enable the driving part 32 to drive the connecting rod 312 to move axially when moving axially, and at the same time, when the connecting part 31 rotates around the axis, the rotation of the connecting rod 312 will not interfere with the driving part 32. That is, the holding mechanism 328 can keep the driving part 32 and the connecting rod 312 relatively stationary axially, and at the same time can keep the rotation of the connecting rod 312 from affecting the driving part 32. It can be understood that when winding and unwinding the wire, the turntable 300 will rotate, and then make the head 10 in contact with it rotate around its axis. The rotation of the head 10 will drive the rotation of the radial spherical bearing 12, and then drive the rotation of the connecting rod 312. Due to the existence of the holding mechanism 328, the rotation of the connecting rod 312 will not affect the driving part 32. With such a setting, the wear between the head 10 and the radial spherical bearing 12 is reduced, the operation stability of the equipment is ensured, and the service time of the equipment is improved. Preferably, the holding mechanism 328 is a deep groove ball bearing 326 and a tapered roller bearing 327.

[0047] Further, in an embodiment of the present invention, an inner cavity 313 is concavely provided at one end of the connecting rod 312 away from the connecting head 311, and the driving rod 332 is disposed in the inner cavity 313.

[0048] It can be understood that in order to prevent interference between the movements of the driving rod 332 and the connecting rod 312, an inner cavity 313 is concavely provided at one end of the connecting rod 312 away from the connecting head 311, and the driving rod 332 is disposed in the inner cavity 313. Preferably, a first gap 314 is provided between the driving rod 332 and the wall of the inner cavity 313, so as to prevent the rotation of the connecting rod 312 from rubbing the surface of the driving rod 332.

[0049] Further, in an embodiment of the present invention, the main body 20 includes a housing 21 and a seat body 22 connected to the housing 21. The housing 21 and the seat body 22 are coaxially arranged to jointly form an installation cavity 23; the seat body 22 is arranged away from the head 10, and a plurality of bearings are provided in the seat body 22.

[0050] It can be understood that by arranging a plurality of bearings in the seat body 22, the driving mechanism 33 can be prevented from moving axially, and the stability of the clamping device 100 is improved.

[0051] Furthermore, in an embodiment of the present invention, a top contact portion 13 is further provided at one end of the head 10 away from the installation groove 11. The top contact portion 13 is frustum-shaped, and the diameter of the top contact portion 13 decreases from the end close to the driving unit 30 to the end away from the driving unit 30.

[0052] It can be understood that by setting the cross-section of the top contact portion 13 as a trapezoid, it can be in top contact with turntables 300 of different specifications, and the applicable range of the clamping device 100 is improved.

[0053] Furthermore, in an embodiment of the present invention, the distance between the connection head 311 and the bottom wall of the installation groove 11 is 2 - 3 mm.

[0054] It can be understood that the distance between the connection head 311 and the bottom wall of the installation groove 11 being 2 - 3 mm can ensure that the chain structure rotates at a certain angle within a certain range, further retaining a certain self - adaptability.

[0055] The present invention also provides a clamping device 400. The clamping device 400 includes a frame 200 and the above - mentioned clamping device 100 fixed on the frame 200. The specific structure of the clamping device 100 in this application refers to the above - mentioned embodiments. Since the clamping device 100 adopts all the technical solutions of the above - mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above - mentioned embodiments, and will not be elaborated here one by one.

[0056] Furthermore, in an embodiment of the present invention, the clamping device 400 is a wire pay - out machine or a wire take - up machine or a wire pay - out and take - up integrated machine.

[0057] It can be understood that the clamping device 100 can be arranged on clamping devices 400 such as a wire take - up machine, a wire pay - out machine, and a wire pay - out and take - up integrated machine for operations such as clamping components such as the turntable 300. The clamping device 400 is provided with a clamping device 100 and a clamping mechanism coaxially arranged with the clamping device 400. The clamping device 100 and the clamping mechanism are respectively installed on both sides of the frame 200. The turntable 300 is arranged between the clamping device 100 and the clamping mechanism. By rotating the handle 331 of the clamping device 100, the distance between the head 10 and the clamping mechanism is reduced to clamp and install the turntable 300.
