Description

Technical Field

[0001] This utility model relates to the field of crimping equipment technology, specifically to an automatic crimping device for connecting tubes and tension clamps. Background Technology

[0002] Tension clamps and straight-line splicing pipes, as important components of transmission lines, are metal accessories that transmit mechanical and electrical loads and provide protection. Conductor crimping is a crucial step in the tension stringing process of transmission line construction, and its quality directly affects the safe operation of the power grid. Currently, the common method for conductor crimping is to fix the crimping machine while the operator moves the conductor and splicing pipe for crimping. In this method, the crimping machine remains stationary while the conductor and splicing pipe are lifted and moved piece by piece for crimping. The movement relies on the operator's visual perception for adjustment. Furthermore, due to varying skill levels, the rework rate for poor crimping quality control remains high. Therefore, the inventor proposes a double-headed crimping device for straight-line splicing pipes and tension clamps, as described in Reference 1.

[0003] Reference 1: Chinese patent document with patent publication number CN218632752U.

[0004] Reference 1 discloses a double-head crimping device for straight-line splicing pipes and tension clamps, which has a platform body, a slide rail mechanism, a material clamping mechanism, a crimping mechanism, and a power supply and electrical control system. The material clamping mechanism has two clamping devices located at both ends of the slide rail mechanism. The crimping mechanism can slide along the track direction of the slide rail mechanism and has two relatively movable crimping heads. The movement path of the crimping heads is perpendicular to the track direction, thereby solving the problem of uneven manual operation skills and low crimping control accuracy during line fitting crimping.

[0005] However, in the actual use of the equipment disclosed in Reference 1, the inventors found that when crimping wire fittings of different thicknesses, it was necessary to repeatedly and tediously change the crimping head to adapt to wire fittings of different thicknesses in order to complete the high-quality crimping process. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the existing technology that crimping connectors require workers to replace them multiple times in order to crimp fittings of different wire thicknesses, and to provide an automatic crimping device for connecting conduits and tension clamps.

[0007] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: an automatic crimping device for splicing pipes and tension clamps, comprising a platform body and a slide rail mechanism disposed on the platform body, a material clamping mechanism for clamping materials being slidably disposed on the slide rail mechanism, a crimping mechanism for crimping line fittings being disposed at the center of the slide rail mechanism, and two symmetrically distributed crimping heads being disposed on the crimping mechanism, each crimping head comprising a snap-fit ​​part and a crimping part, the crimping head being movably connected to the crimping mechanism through the snap-fit ​​part, the cross-section of the crimping part being a semi-circular ring, and the openings of the crimping parts of the two crimping heads being arranged opposite to each other;

[0008] The crimping part is provided with a first crimping plate, a second crimping plate and a third crimping plate. A transition crimping plate is provided between the first crimping plate and the second crimping plate and between the second crimping plate and the third crimping plate. A groove is provided on the first crimping plate, the second crimping plate and the third crimping plate. Both ends of the transition crimping plate are placed in the grooves of the corresponding crimping plates.

[0009] The pressing part is provided with a driving component capable of driving the first pressing plate to move laterally;

[0010] The pressing part is provided with a limiting component that can guide the vertical movement of the second pressing plate and the third pressing plate.

[0011] As a further optimization of the automatic crimping device for splicing tubes and tension clamps of this utility model: two drive components are provided, which are respectively located on both sides of the length direction of the crimping part, and the two drive components are fixedly connected to the part of the second crimping plate that extends beyond the crimping part.

[0012] As a further optimization of the automatic crimping device for splicing tubes and tension clamps of this utility model: the driving component includes a positioning seat fixedly disposed on the crimping part, an electric push rod fixedly disposed inside the positioning seat, and the telescopic end of the electric push rod being fixedly connected to the portion of the second crimping plate that extends beyond the crimping part.

[0013] As a further optimization of the automatic crimping device for splicing tubes and tension clamps of this utility model: four limiting components are provided, and the four limiting components are arranged in pairs on both sides of the length direction of the crimping part. Any pair of limiting components is fixedly connected to the portion of the first crimping plate and the third crimping plate that extends beyond the crimping part.

[0014] As a further optimization of the automatic crimping device for splicing tubes and tension clamps of this utility model: the limiting rod is slidably engaged with the limiting seat fixedly disposed on the side of the crimping part, and the limiting rod is fixedly connected to the part of the first crimping plate or the third crimping plate that extends beyond the crimping part.

[0015] As a further optimization of the automatic crimping device for splicing tubes and tension clamps of this utility model: the included angle of the transition crimping plate is equal to the included angle of any hexagon.

[0016] As a further optimization of the automatic crimping device for splicing tubes and tension clamps of this utility model: the first crimping plate, the second crimping plate and the third crimping plate are all fixedly provided with reinforcing ribs on the side facing the inner wall of the crimping part.

[0017] As a further optimization of the automatic crimping device for splicing tubes and tension clamps of this utility model: a mating member is provided between the crimping parts of both crimping joints, and the mating member includes a mating protrusion and a mating concave block that are fixedly connected to the opposite ends of the two crimping parts respectively.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention uses a crimping joint with a first crimping plate and a third crimping plate inside the crimping part to restrict its vertical displacement in conjunction with a limiting component on the crimping part. A driving component on the second crimping plate causes it to move laterally. A transition crimping plate connecting the first, second, and third crimping plates causes it to move radially when the second crimping plate moves laterally. Therefore, when the two crimping parts are joined, the two sets of first, second, third, and transition crimping plates can be hexagonal of different sizes to accommodate wire fittings of different thicknesses. This allows workers to drive the two crimping joints closer together to crimp wire fittings of different thicknesses using the crimping mechanism. Attached Figure Description

Detailed Implementation

[0025] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0026] like Figure 1 As shown, an automatic crimping device for splicing tubes and tension clamps includes a crimping mechanism 4, a material clamping mechanism 3, a slide rail mechanism 2, and a platform body 1. The crimping mechanism 4 is connected to two symmetrically arranged crimping heads 5. The crimping mechanism 4 is used to cooperate with the crimping heads 5 to crimp the line fittings. The slide rail mechanism 2 is used to adjust the position of the material clamping mechanism 3, thereby achieving the purpose of high-precision control of the crimping accuracy.

[0027] like Figure 2 and Figure 4 As shown, the crimp connector 5 includes a snap-fit ​​portion 504 and a crimping portion 508. The crimp connector 5 is movably connected to the crimping mechanism 4 through the snap-fit ​​portion 504. The crimping portion 508 is annular. The openings of the crimping portions 508 of the two crimp connectors 5 are opposite each other. Each crimping portion 508 is provided with a first crimping plate 503a, a second crimping plate 503b, and a third crimping plate 503c. The second crimping plate 503b is connected to the first crimping plate 503a and the third crimping plate 503c respectively through two transition crimping plates 505. Thus, the two sets of first crimping plates 503a, second crimping plates 503b, and third crimping plates 503c in the two crimping portions 508 form a hexagon when the two crimping portions 508 are mated.

[0028] The first pressing plate 503a has a first groove on the side facing the second pressing plate 503b, and the third pressing plate 503c has a second groove on the side facing the second pressing plate 503b. The second pressing plate 503b also has a third groove on the side facing both the first pressing plate 503a and the second pressing plate 503b. The two third grooves allow the cross-section of the second pressing plate 503b to be H-shaped, and the transition pressing plate 505 inserted into the two third grooves serves as a support to maintain the structural stability of the second pressing plate 503b. Two transition pressing plates 505 are movably connected to the second and third grooves respectively, on the side away from the third groove. Thus, without penetrating the first pressing plate 503a and the third pressing plate 503c, the structural stability of the first pressing plate 503a and the third pressing plate 503c is maintained, thereby achieving high-quality pressing of the wiring fittings.

[0029] The first pressing plate 503a, the second pressing plate 503b, and the third pressing plate 503c are all fixedly provided with reinforcing ribs 507 on the side facing the inner wall of the pressing part 508. The reinforcing ribs 507 are used to maintain the structural stability of the first pressing plate 503a, the second pressing plate 503b, and the third pressing plate 503c, thereby maintaining a high-quality line fitting pressing.

[0030] Four drive assemblies 502 are provided, and the four drive assemblies 502 are respectively provided on both sides of the crimping part 508 along its length. Each drive assembly 502 includes a positioning seat 5021 fixedly provided at the center of the crimping part 508. An electric push rod 5022 is fixedly connected to the positioning seat 5021. The telescopic end of the electric push rod 5022 away from the positioning seat 5021 is fixedly provided on the second crimping plate 503b. Specifically, the electric push rod 5022 can be replaced with a hydraulic rod, or a threaded cylinder rotatably provided on the positioning seat 5021 and a threaded rod threadedly connected to the threaded cylinder, with the end of the threaded rod away from the threaded cylinder rotatably provided on the second crimping plate 503b. It can also be replaced with other structures, as long as it can drive the second crimping plate 503b to move laterally and maintain sufficient support for the second crimping plate 503b.

[0031] There are eight limiting components 506. The eight limiting components 506 are divided into two groups and are respectively located on both sides of the crimping part 508 in the length direction. Each limiting component 506 includes a limiting seat 5061 fixedly mounted on the crimping part 508. A vertically arranged limiting rod 5062 is slidably connected in the limiting seat 5061. The end of the limiting rod 5062 is fixedly connected to the end of the first crimping plate 503a or the second crimping plate 503b that extends beyond the crimping part 508.

[0032] The transition pressing plate 505 is V-shaped, and the included angle of the transition pressing plate 505 is equal to any included angle of the hexagon.

[0033] Both crimping connectors 5 include crimping portions 508 with mating parts 501 on their opposite surfaces. The mating parts 501 include mating protrusions 5011 and mating recesses 5012 respectively provided on the opposite surfaces of the other two crimping portions 508. When the two crimping portions 508 approach each other to crimp the circuit metal under the drive of the crimping mechanism 4, the two crimping portions 508 form a stable ring, thereby reducing the structural stability of the two crimping portions 508, that is, reducing the probability of the crimping portions 508 deforming due to strong extrusion, and thus maintaining the quality of crimping the circuit hardware.

[0034] like Figure 2 and Figure 3 As shown, when it is necessary to crimp connecting fittings of different thicknesses, the second crimping plate 503b can be displaced by the drive component 502. When the second crimping plate 503b moves laterally, it will drive the two transition crimping plates 505 to move laterally, so that the two transition crimping plates 505 are pulled out from the first groove and the second groove. However, since the first crimping plate 503a and the second crimping plate 503b with the first groove and the second groove are both set at an angle, the first crimping plate 503a and the second crimping plate 503b will tend to move. Subsequently, the first crimping plate 503a and the second crimping plate 503b will be subject to the corresponding limitations. Component 506 restricts vertical displacement, while the vertical displacement of the first pressing plate 503a and the second pressing plate 503b drives the two transition pressing plates 505 to move vertically synchronously and extend from the two third grooves. Then, the transition pressing plate 505 will move radially to cooperate with the first pressing plate 503a, the second pressing plate 503b and the third pressing plate 503c. When the two pressing parts 508 are mated, the two sets of first pressing plates 503a, second pressing plates 503b, third pressing plates 503c and transition pressing plates 505 form hexagons of different sizes to press wire fittings of different thicknesses.

[0035] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
