DETAILED DESCRIPTION

[0040] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The present invention uses the terms "first", "second", etc. to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0044] Reference Figure 1 , Figure 2 and Figure 3, a wire clamp according to an embodiment of the present invention comprises: a clamp base 1, a synchronization mechanism 2, at least three groups of clamping jaw mechanisms 3, wherein the clamping jaw mechanisms 3 comprise a clamping jaw assembly 31, a clamping jaw track 32 and a driving assembly 33;

[0045] The clamp rail 32 is arranged on the clamp base 1 and extends radially along the clamp base 1. A plurality of the clamp rails 32 are arranged at equal intervals along the circumference of the clamp base 1. The clamp assembly 31 is movably arranged on the clamp rail 32. The driving assembly 33 is arranged on the clamp base 1 and connected to the clamp assembly 31. The driving assembly 33 is used to drive the clamp assembly 31 to move along the clamp rail 32. The clamp assembly 31 has a clamping portion 311 for clamping the wire. The clamping portion 311 is arranged radially away from the clamp base 1 along the clamp base 1. The synchronization mechanism 2 is arranged on the clamp base 1. A plurality of the clamp assemblies 31 are transmission-connected through the synchronization mechanism 2.

[0046] According to the principle of three points defining a plane, the clamping mechanism 3 is provided with at least three groups, which can ensure the stability of the center of gravity plane of the clamped wire roll. Specifically, the clamping mechanism 3 can be set to three groups, wherein the corresponding three clamping parts 311 are radially oriented away from the central axis direction of the clamp base 1. The moving stroke of the clamping jaw assembly 31 can be adjusted by adjusting the clamping jaw track 32, thereby controlling the size specification range of the clampable wire. The driving assembly 33 drives the clamping jaw assembly 31 so that the clamping part 311 performs an opening and closing action accordingly. The clamping part 311 can pass through the center of the electric cable formed by the wire winding by using the opening and closing action, and form a clamping connection with the electric cable, thereby realizing the clamping and placement of the electric cable by the wire clamp. The synchronization mechanism 2 can ensure the position accuracy of each clamping jaw assembly 31 during execution, so that the center of the circle enclosed by multiple clamping jaw assemblies 31 is consistent with the center of the wire roll, thereby improving the stability of the center of gravity plane of the electric cable. The wire clamp of the present application can adapt to wires of different specifications during the sorting operation, thereby improving the overall efficiency of clamping.

[0047] Reference Figure 4 and Figure 5 In some improved schemes of the present application, the clamp assembly 31 includes a clamp base 312, a clamp body 313 and a buffer pad 314. The clamp base 312 is movably arranged on the clamp track 32 and is connected to the driving assembly 33. The clamp body 313 is protruded on the side of the clamp base 312 away from the clamp track 32. The clamp body 313 is defined to form the clamping portion 311 along a side of the clamp base 1 radially away from the clamp base 1, and the buffer pad 314 is laid on the clamping portion 311.

[0048] A slider may be provided at the bottom of the clamp base 312, and is slidably connected to the clamp rail 32 through the slider. The buffer pad 314 is supported by an elastic material, and is used to ensure that the contact surface between the clamping portion 311 and the cable is soft during the clamping process, and to prevent the wire clamp from losing the insulation layer of the wire. Specifically, the clamp base 312 and the clamp body 313 are both made of steel, and the compressibility is basically zero during use. The buffer pad 314 can be composed of polyurethane to form a flexible protective rubber pad to protect the wire during clamping.

[0049] Reference Figure 6 In some improved solutions of the present application, the buffer pad 314 includes a plurality of buffer sub-pads 3141 arranged in sequence from the outside to the inside along the radial direction of the fixture base 1, and in two adjacent buffer sub-pads 3141: the hardness of the buffer sub-pad 3141 located on the outside is less than the hardness of the buffer sub-pad 3141 located on the inside. Specifically, the buffer sub-pads 3141 can be made of polyurethanes of different hardness, and the buffer pads 314 are stacked in a manner of gradually decreasing hardness from the inside to the outside to form the buffer pad 314.

[0050] When clamping wires of different diameters, the cushion 314 will produce different deformations. Because wires are usually rolled up in 100-meter rolls, wires with larger diameters are heavier than wires with smaller diameters at the same length, and require greater clamping force. Figure 7 and Fig. 9 The vertical direction of the buffer pad 314 can ensure that it has more contact surface with the wire because the outer buffer sub-pad 3141 has lower hardness and larger deformation, and can also provide a certain support effect. Compared with relying solely on friction, it is helpful to reduce the clamping force and further prevent the outer insulation layer of the wire from being damaged. Figure 8 and Fig.10 When clamping a small-diameter wire, the outer buffer pad 3141 can be compressed more due to its low hardness, and can basically achieve complete contact with the outer wall of the wire roll. At the same time, it can also be deformed vertically to fill the gap to increase the contact area, while providing a certain vertical supporting force.

[0051] In some improved solutions of the present application, the clamping portion 311 is in the shape of an arc that bulges away from the clamp base 1. It can be adapted to the inner circumferential wall formed by the winding of the wire, and the contact area between the clamping portion 311 and the wire roll is increased. Specifically, the diameter of the arc can be designed according to the inner circumferential wall of the wire roll formed by the winding of the wire with the maximum wire diameter specification, so as to adapt to wires of all wire diameter specifications, and at the same time, the contact area between the clamping portion 311 and the wire can be maximized when the wire diameter is large.

[0052] Reference Figure 2In some improved schemes of the present application, the driving assembly 33 includes a driving cylinder 331, and the driving cylinder 331 is arranged on the clamp base 1 and extends along the extension direction of the clamp track 32, and the power output end of the driving cylinder 331 is connected to the clamp assembly 31. Specifically, the power output end of the driving cylinder 331 can be welded to the clamp base 312. When the driving cylinder 331 is inhaled or exhausted to produce expansion and contraction, it drives the clamp assembly 31 to move in a straight line. The driving cylinder 331 is used as a driving device, which has a simple structure and is easy to maintain and install, and the air source 51 can be externally arranged, which can reduce the overall size and load of the wire clamp, and the stability and accuracy can be guaranteed with the cooperation of the synchronization mechanism 2.

[0053] Reference Figure 14 to Figure 16 In some improved solutions of the present application, a protective cover 4 is further included, the clamp base 1 has a first side surface 11 and a second side surface 12 arranged opposite to each other, the clamp track 32 is arranged on the first side surface 11, the clamp assembly 31 is convexly arranged on the side of the clamp track 32 away from the clamp base 1, the protective cover 4 and each of the driving cylinders 331 are arranged on the second side surface 12, and the protective cover 4 covers a plurality of the driving cylinders 331 along the circumferential direction. The protective cover 4 can provide safety protection for each operating mechanism of the entire wire clamp to prevent foreign objects from invading and personnel from being injured.

[0054] In some improved schemes of the present application, the synchronization mechanism 2 includes a synchronization belt 21 and the same number of synchronization pulleys 22 as the clamping mechanism 3. The synchronization pulleys 22 are rotatably arranged on the clamp base 1 and are transmission connected to the clamping jaw assembly 31. The synchronization belt 21 is arranged around each of the synchronization pulleys 22 so that each of the synchronization pulleys 22 is transmission connected through the synchronization belt 21.

[0055] Specifically, the synchronous pulley 22 is connected to the clamp base 312 in the clamp assembly 31. When the multiple driving cylinders 331 drive each clamp base 312 to move telescopically on the clamp track 32, the synchronous pulley 22 is used to connect the synchronous belt 21 to the clamp base 312, so that the moving and retracting lengths can be kept consistent, which is beneficial to ensure that the center of the circle formed by the multiple clamp bodies 313 remains unchanged, so that the clamping force of the multiple groups of clamp bodies 313 on the wire roll is consistent, and the situation that a certain clamp body 313 does not clamp the wire and fails to clamp is prevented.

[0056] In some improved schemes of the present application, the synchronization mechanism 2 also includes a plurality of synchronization gears 23, the synchronization gears 23 are coaxially connected to the synchronization pulley 22, the clamping jaw assembly 31 is provided with a synchronization rack 315 adapted to the synchronization gear 23, the synchronization rack 315 extends along the extension direction of the clamping jaw rail 32, and the synchronization gear 23 is transmission-connected to the synchronization rack 315.

[0057] Specifically, refer to Figure 11 to Figure 13 The synchronous rack 315 and the synchronous gear 23 are both located on the first side 11 of the fixture base 1, the synchronous pulley 22 and the synchronous belt 21 are both located on the second side 12 of the fixture base 1, and the synchronous belt 21 is sleeved on each synchronous pulley 22. The fixture base 1 is also provided with a plurality of bearing supports, through which a synchronous shaft is mounted, and each synchronous gear 23 and each synchronous pulley 22 are mounted on both sides of the synchronous shaft in a one-to-one correspondence, so that the synchronous gear 23 and the synchronous pulley 22 can achieve synchronous rotation. The synchronous rack 315 can be arranged on the clamping jaw base 312 of the clamping jaw assembly 31. When the synchronous rack 315 moves linearly along the clamping jaw track 32 with the clamping jaw base 312, it engages with the synchronous gear 23 to drive the synchronous gear 23 to rotate. The rotation of the synchronous gear 23 on the first side 11 drives the synchronous pulley 22 located on the second side 12 of the clamp base 1 to rotate. Each synchronous pulley 22 is engaged with the synchronous belt 21 to achieve the consistency of the rotation angle of each synchronous gear 23, thereby achieving the consistency of the moving stroke of the clamping jaw base 312 at any time.

[0058] The protective cover 4 is disposed on the second side surface 12 of the fixture base 1 , and is also circumferentially disposed on the synchronous belt 21 and each synchronous pulley 22 to protect the synchronous mechanism 2 .

[0059] Reference Fig.17 In some improved schemes of the present application, it includes an air source 51, a reversing circuit 52, at least two groups of control circuits 53 and the same number of execution circuits 54 as the clamping mechanism 3. The air source 51 is connected to the reversing circuit 52 through each of the control circuits 53. The control circuit 53 is connected in series with a first solenoid valve 531, a manual pressure regulating valve 532 and a second solenoid valve 533 in sequence. The reversing circuit 52 is connected to each of the execution circuits 54 respectively. Each of the driving cylinders 331 is connected to each of the execution circuits 54 in a one-to-one correspondence. The execution circuit 54 is connected in series with a first one-way throttle valve 541 and a second one-way throttle valve 542. The driving cylinder 331 is connected between the first one-way throttle valve 541 and the second one-way throttle valve 542.

[0060] After the high-pressure gas source 51 is connected, it is divided into multiple groups of control loops 53. The specific number of control loops 53 can be set according to actual needs. In the specific embodiment of the present application, it is set to 3 control loops 53, and each control loop 53 is connected in series with a first solenoid valve 531, a manual pressure regulating valve 532 and a second solenoid valve 533. The first solenoid valve 531 and the second solenoid valve 533 are used to ensure the harm of reverse airflow of the pressure regulating valve in other loops, avoid the normal operation of the pressure regulating valve due to the wrong flow direction of the gas, and reduce the risk of damage to the pressure regulating valve. Through the control of the upper system, the first solenoid valve 531 and the second solenoid valve 533 in series on the control loop 53 that is actually needed are opened to ensure smooth gas flow and achieve the control purpose.

[0061] Since the moving stroke and clamping force required by the driving cylinder 331 are different for clamping wires of different wire diameters, the manual pressure regulating valve 532 is used to adjust the air pressure according to the stroke and clamping force, so that the sum of the forces output by the multiple driving cylinders 331 is sufficient to clamp the wires and keep them from falling off during the movement and damaging the insulation layer of the voltage wires. Specifically, the actual adjustment can be made by measuring the wire reels of different wire diameters on site, wherein wire reels of similar wire diameters and weights can be grouped together and the same control loop 53 is used for clamping. Therefore, before operation, it is necessary to classify and count the wires of all specifications, and set similar specifications as one loop. If there are several similar specifications, several control loops 53 need to be set.

[0062] By controlling the direction of the reversing circuit 52, the extension or retraction of the driving cylinder 331 is controlled to achieve the opening and closing of the wire clamp. The execution circuit 54 is responsible for executing the action. At the same time, by controlling the first one-way throttle valve 541 and the second one-way throttle valve 542, the speed of the extension and retraction of the driving cylinder 331 can be controlled to prevent the driving cylinder 331 from moving too fast and causing impact on the wire and damaging the insulation layer of the wire.

[0063] A preferred embodiment of the present invention provides a control method for a wire clamp, which is used for the above-mentioned wire clamp, and comprises the following steps:

[0064] S1 classifies wires of different specifications and groups wires of similar specifications into one group;

[0065] S2 matches each control circuit 53 with each group of wires one by one, and adjusts the manual pressure regulating valve 532 in each control circuit 53 so that its output force is compatible with the specification of the wires in the corresponding group;

[0066] S3 selects the corresponding control circuit 53 to be connected to the reversing circuit 52 according to the specification of the wire to be clamped, and uses the reversing circuit 52 to be connected to the execution circuit 54 to control the extension or retraction of each driving cylinder 331.

[0067] In summary, the embodiments of the present invention provide a wire clamp and a control method thereof, which have the following advantages:

[0068] 1) The clamping mechanism 3 is driven in groups, and a synchronization mechanism 2 is set to achieve a synchronization effect, so as to ensure that the position of each clamping body 313 is accurate and the center of the clamping body 313 is consistent with the center of the wire roll;

[0069] 2) Improve the original two-claw clamping to three-claw or even multi-claw clamping to ensure the stability and reliability of the wire clamp;

[0070] 3) The flexible adjustment of the movement stroke of the clamp body 313 is achieved by driving the air cylinder 331, thereby increasing the stroke adjustment range and thus increasing the diameter range of the wire coil that can be clamped;

[0071] 4) multiple layers of polyurethane material with multiple hardness are provided to form the buffer pad 314 to ensure that the contact area between the clamping portion 311 and the wire is maximized;

[0072] 5) The cylinder control method of setting multiple control loops 53 can flexibly adapt to the clamping needs of wire rolls of different or similar specifications.

[0073] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
