Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grounding wire crimping, and relates to an auxiliary device, particularly a grounding wire crimping auxiliary device. Background Technology
[0002] In the fields of power system construction, electrical equipment installation, and power transmission and transformation maintenance, reliable crimping of grounding wires is a crucial step in ensuring the safe operation of equipment. Traditional crimping operations generally rely on manual hand positioning. The operator needs to hold the grounding cable and terminal with one hand and apply pressure with crimping pliers with the other. This depends on personal experience to judge the crimping position, which can easily lead to misalignment of the crimping position and deformation of the terminal. In batch operations, this results in low efficiency and poor crimping quality. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a grounding wire pressing auxiliary device to solve these problems.
[0004] The objective of this utility model can be achieved through the following technical solution: a grounding wire pressing auxiliary device, characterized in that it includes:
[0005] The machine base is arranged in an L-shape, and a tooling table is provided on the machine base;
[0006] The pressing mechanism includes an upper die and multiple detachable lower dies mounted on a tooling table. The upper die is controlled by a drive mechanism to move in the vertical direction and complete the pressing.
[0007] The positioning mechanism includes a guide rail frame laid on the base, a movable slide mounted on the guide rail frame, a drive unit, and a clamp first and a clamp second for clamping the two ends of the grounding wire.
[0008] The first clamp is fixed on the machine base, and the second clamp is fixed on the movable slide. The two are arranged opposite to each other. The movable slide is driven to move axially through the drive unit to achieve the tensioning and straightening positioning of the grounding wire.
[0009] Both the first and second chucks are embedded with pressure sensors to monitor and provide feedback on the clamping force in real time, preventing overload damage to the grounding wire.
[0010] In the above-mentioned grounding wire pressing auxiliary device, the number of the lower mold, clamp one and clamp two are equal and arranged at intervals. The lower mold is a modular quick-change structure and can be connected to the tooling table through magnetic buckles.
[0011] In the aforementioned grounding wire pressing auxiliary device, the driving unit is a ball screw transmission mechanism driven by a servo motor, which supports closed-loop control of speed and displacement.
[0012] In the aforementioned grounding wire pressing auxiliary device, the driving mechanism is a hydraulic cylinder, and its output end integrates a displacement sensor for real-time monitoring of the pressing stroke accuracy.
[0013] Compared with existing technologies, this grounding wire pressing auxiliary device has the following advantages:
[0014] 1. The lower mold adopts a magnetic snap-on quick-change structure, which supports the rapid switching of multiple grounding wire specifications, improving production flexibility and maintenance efficiency. The number of chucks and the lower mold are equal and arranged at intervals, which facilitates synchronous operation during batch production.
[0015] 2. The ball screw transmission mechanism driven by the servo motor realizes closed-loop control to ensure the displacement and speed accuracy of the grounding wire tension and positioning. The hydraulic cylinder integrates a displacement sensor to monitor the pressing stroke in real time, ensuring the consistency of pressing and avoiding quality problems caused by stroke deviation.
[0016] 3. The chuck has a built-in pressure sensor that provides real-time feedback on the clamping force, preventing overload damage to the grounding wire and improving operational safety. The L-shaped base has a compact design, and the tooling table and guide rail are rationally laid out, balancing space utilization and ease of operation. Attached Figure Description

[0018] In the diagram, 1 is the machine base; 2 is the tooling table; 3 is the upper mold; 4 is the lower mold; 5 is the drive mechanism; 6 is the guide rail frame; 7 is the movable slide; 8 is the drive unit; 9 is the first chuck; and 10 is the second chuck. Detailed Implementation
[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0020] like Figure 1As shown, this grounding wire pressing auxiliary device includes an L-shaped base 1 with a tooling table 2 on the base 1; a pressing mechanism including an upper mold 3 and multiple detachable lower molds 4 mounted on the tooling table 2. The lower molds 4 adopt a magnetic snap-fit quick-change structure, supporting rapid switching of multiple grounding wire specifications, improving production flexibility and maintenance efficiency. The upper mold 3 can move vertically and complete the pressing by a drive mechanism 5; a positioning mechanism including a guide rail frame 6 laid on the base 1, a movable slide 7 movably mounted on the guide rail frame 6, a drive unit 8, and clamps 9 and 10 for clamping the two ends of the grounding wire; clamp 9 is fixed on the base 1, and clamp 10 is fixed on the movable slide 7. The two are arranged opposite each other. The drive unit 8 drives the movable slide 7 to move axially, realizing the tensioning and straightening positioning of the grounding wire; both clamps 9 and 10 are embedded with pressure sensors to monitor the clamping force in real time and provide feedback to prevent overload damage to the grounding wire.
[0021] The number of lower mold 4, chuck 1 9 and chuck 2 10 are equal and arranged at intervals. The lower mold 4 is a modular quick-change structure and can be connected to the tooling table 2 by magnetic snap-fit. The number of chucks is equal to that of the lower mold 4 and arranged at intervals, which facilitates synchronous operation during batch production.
[0022] The drive mechanism 5 is a hydraulic cylinder with a displacement sensor integrated at its output end for real-time monitoring of the pressing stroke accuracy. The drive unit 8 is a ball screw transmission mechanism driven by a servo motor, which supports closed-loop control of speed and displacement. The servo motor-driven ball screw transmission mechanism achieves closed-loop control to ensure the displacement and speed accuracy of the grounding wire tension and positioning. The hydraulic cylinder integrates a displacement sensor to monitor the pressing stroke in real time, ensuring pressing consistency and avoiding quality problems caused by stroke deviation.
[0023] Working principle
[0024] Positioning stage: Clamp 1 9 (fixed) and clamp 2 10 (movable) hold both ends of the grounding wire. The servo motor drives the ball screw to move the moving slide 7 axially, so that the grounding wire is tensioned and straightened. The pressure sensor monitors the clamping force in real time to ensure that the tension is appropriate and to avoid damage to the wire.
[0025] Pressing stage: The hydraulic cylinder drives the upper mold 3 to press down vertically, and cooperates with the lower mold 4 on the tooling table 2 to complete the pressing. The displacement sensor provides real-time feedback of the pressing stroke data to ensure that the pressing depth is consistent each time.
[0026] Quick switching: Different specifications of lower mold 4 (or other quick connection structures) can be replaced by magnetic buckles to adapt to the pressing requirements of multiple grounding wire models.
