[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
[0025] Embodiment 1
[0026] Please refer to Figures 1 - 5, the present utility model provides a technical solution: a wire clamp installation tool with a clamping function, including an installation base 1, on which two clamping jaws 2 are arranged. The two clamping jaws 2 are symmetrically arranged, and each clamping jaw 2 is respectively connected with a driving cylinder 3. The two driving cylinders 3 are fixedly arranged on the installation base 1, and the two driving cylinders 3 respectively drive the two clamping jaws 2 to perform opening and closing actions; a fixture seat 6 is arranged on the installation base 1, and arranging the fixture seat 6 facilitates the external robotic arm or robotic arm to grab the fixture seat 6.
[0027] A wire clamp pre-tightening mechanism 7 is also arranged on the installation base 1, and the wire clamp pre-tightening mechanism 7 is used to cooperate with the wire clamp 5 to be installed (hereinafter referred to as the wire clamp); specifically, the wire clamp pre-tightening mechanism 7 includes a pre-tightening motor 71 installed on the installation base 1, the output end of the pre-tightening motor 71 is connected with a sleeve seat 72, and a hexagonal groove 73 is arranged on the sleeve seat 72.
[0028] The wire clamp 5 adopts the existing wire clamp structure for high-voltage cables, which is used for connecting the drainage wire and the main wire. That is, it has an upper shell 51, a lower shell 52, an upper clamping plate 53, a lower clamping plate 54, a wire clamp bolt 55 and a nut 56. The upper clamping plate 53 and the lower clamping plate 54 are correspondingly arranged. The upper clamping plate 53 and the lower clamping plate 54 are made of materials with good electrical conductivity, and a spring is arranged between the upper clamping plate 53 and the lower clamping plate 54. A wire clamp bolt 55 is arranged between the upper clamping plate 53 and the lower clamping plate 54. The wire clamp bolt 55 penetrates through the upper clamping plate 53 and the lower clamping plate 54, and the external thread of the wire clamp bolt 55 is in threaded cooperation with the nut 56. The nut 56 is just clamped in the upper shell 51 and is limited by the upper shell 51. The lower clamping plate 54 is fixedly arranged on the lower shell 52, and the upper shell 51 is matched with the lower shell 52. The opposite outer walls of the lower shell 52 are in contact with the upper shell 51. As Figure 2 shown, the two triangular parts protruding from the upper shell 51 are just located outside the opposite outer walls of the lower shell 52. This is the prior art and will not be elaborated here; the outer hexagonal structure of the head of the wire clamp bolt 55 is just adapted to the hexagonal groove 73 on the sleeve seat 72. By fitting the wire clamp bolt 55 of the wire clamp 5 into the hexagonal groove 73 on the sleeve seat 72, the support and limitation of the wire clamp bolt 55 are realized, so as to realize the cooperation between the wire clamp 5 and the wire clamp pre-tightening mechanism 7; when the upper shell 51 of the wire clamp 5 is limited and fixed, the sleeve seat 72 is driven to rotate by the pre-tightening motor 71, so as to drive the wire clamp bolt 55 of the wire clamp 5 to rotate. Since the nut 56 of the wire clamp 5 is limited by the upper shell 51, and the upper shell 51 and the lower shell 52 are matched, the upper shell 51 and the nut 56 of the wire clamp 5 can be promoted to move towards the sleeve seat 72, further driving the upper clamping plate 53 to move downward close to the lower clamping plate 54, so as to realize the clamping work, that is, clamping the drainage wire and the main wire.
[0029] Meanwhile, the lower clamping plate 54 of the wire clamp 5 is fixed on the upper housing 51. After the wire clamp 5 is fitted on the wire clamp pre-tightening mechanism 7, the position of one of the clamping grooves on the lower clamping plate 54 corresponds to the clamping area of the clamping jaws 2. The two clamping jaws 2 are used to clamp the drainage wire, and the opening and closing degree of the clamping jaws 2 is controlled by controlling the driving cylinder 3, so that the drainage wire with different wire diameters can be clamped. When the two clamping jaws 2 clamp the drainage wire, the part of the drainage wire between the two clamping jaws 2 just corresponds to the middle position of a clamping groove on the lower clamping plate 54, and the other clamping groove on the lower clamping plate 54 is used to clamp the main wire. That is, the upper clamping plate 53 and the lower clamping plate 54 of the wire clamp 5 are driven by the pre-tightening motor 71 to drive the sleeve seat 72 to rotate, so as to clamp the drainage wire and the main wire.
[0030] Embodiment 2
[0031] Please refer to 1- Figure 6 Referring to FIG. 1, on the basis of Embodiment 1, a wire clamp clamping mechanism 4 is further provided.

The two threaded seats 41 are movably arranged on the mounting seat 1, and a clamping assembly 44 is respectively arranged on the two threaded seats 41. The two clamping assemblies 44 are symmetrically arranged. A driving assembly 43 is further arranged on the mounting seat 1. The driving assembly 43 is used to drive the rotation of the lead screw 42. Since the lead screw 42 is provided with a left-handed and right-handed thread and the threaded seats 41 are movably arranged on the mounting seat 1, the two threaded seats 41 can move synchronously towards each other or away from each other, and further the two clamping assemblies 44 can move synchronously towards each other or away from each other.
[0032] The driving assembly 43 includes a driving motor 431 mounted on the mounting seat 1. A pulley 432 is sleeved on the output end of the driving motor 431, and a pulley 432 is also sleeved on the outside of the lead screw 42. A transmission belt 433 is arranged in cooperation between the two pulleys 432. That is, the driving motor 431 drives the pulley 432 connected thereto to rotate. Under the action of the transmission belt 433, the other pulley 432 is driven to rotate, so as to realize the rotation of the lead screw 42, and further realize the movement of the clamping assembly 44.
[0033] The clamping assembly 44 includes a support frame 441 which is fixedly arranged on the threaded seat 41; and when the wire clamp 5 cooperates with the wire clamp pre-tightening mechanism 7, the wire clamp 5 is located between the two support frames 441; a clamping head 442 is arranged on the support frame 441, and a limit buckle 443 is hinged on the clamping head 442. Specifically, the top end of the limit buckle 443 is hinged on the clamping head 442, and a limit spring 444 is arranged between the limit buckle 443 and the support frame 441; at the same time, first clamping grooves 511 adapted to the clamping heads 442 are respectively arranged on both sides of the upper shell 51 of the wire clamp 5, and second clamping grooves 512 adapted to the limit buckles 443 are respectively arranged on both sides of the upper shell 51 of the wire clamp 5; by driving the motor 431 to work, the lead screw 42 is driven to rotate, so that the two support frames 441 can be driven to move synchronously towards each other, thereby driving the two clamping heads 442 to be respectively clamped in the first clamping grooves 511 on both sides of the upper shell 51, and at the same time driving the two limit buckles 443 to be respectively clamped in the second clamping grooves 512 on both sides of the upper shell 51, so as to realize the clamping and limiting of the wire clamp 5; and under the action of the limit spring 444, the clamping effect of the limit buckle 443 on the wire clamp 5 can be improved.
[0034] In this embodiment, when performing the operation of connecting the bypass wire, first, the wire clamp 5 is cooperated with the wire clamp pre-tightening mechanism 7, that is, the head of the wire clamp bolt 55 of the wire clamp 5 is cooperated in the hexagonal groove 73 on the sleeve seat 72, and the two clamping heads 442 are respectively clamped in the first clamping grooves 511 on both sides of the upper shell 51, and at the same time driving the two limit buckles 443 to be respectively clamped in the second clamping grooves 512 on both sides of the upper shell 51; at the same time, the two driving cylinders 3 drive the two clamping jaws 2 to be in an open state; then, the two robotic arms respectively grab the bypass wire and the fixture seat 6, and the robotic arm grabbing the fixture seat 6 drives the mounting seat 1 and the wire clamp 5 to move, so that the end of the bypass wire is passed through the two clamping jaws 2, and the lower clamping plate 54 of the wire clamp 5 is located corresponding to the middle of the clamping groove of the clamping jaw 2 at the position corresponding to the end of the bypass wire; then, the two driving cylinders 3 respectively drive the two clamping jaws 2 to perform a closing action to realize the clamping of the end of the bypass wire. At this time, the robotic arm clamping the bypass wire can be separated from the bypass wire, and the bypass wire is clamped on the two clamping jaws 2.
[0035] Finally, the robotic arm of the gripping fixture base 6 carries the mounting base 1, the wire clamp 5, and the bypass wire close to the main wire, and positions the main wire between the clamping grooves on the upper clamping plate 53 and the lower clamping plate 54 that do not correspond to the clamping jaws 2. By controlling the driving motor 431 to drive the lead screw 42 to rotate, the two threaded seats 41 are synchronously moved away from each other, thereby driving the clamping heads 442 and the limit buckles 443 to disengage from the first clamping groove 511 and the second clamping groove 512. At the same time, by operating the pre-tightening motor 71, the sleeve base 72 is driven to rotate, and the sleeve base 72 drives the wire clamp bolt 55 to rotate, prompting the upper clamping plate 53 to move towards the lower clamping plate 54, thereby realizing the clamping of the bypass wire and the main wire. After the bypass wire and the main wire are clamped, the two driving cylinders 3 respectively control the two clamping jaws 2 to perform an opening action to release the clamping of the bypass wire. At this time, the robotic arm drives the mounting base 1 to move, so that the components mounted thereon are separated from the wire clamp 5, and the bypass wire can be connected to the main wire.
[0036] In this embodiment, the bypass wire can be separately grasped by the clamping jaws 2. After grasping the bypass wire, it is convenient to clamp the bypass wire and the main wire on the wire clamp 5, that is, it is convenient to connect the bypass wire to the main wire.
