Description
Technical Field
The invention relates to the technical field of crimping of electrical appliance lead terminals, in particular to a positioning device and a positioning method of an electro-hydraulic clamp crimping terminal.
Background
At present, in order to ensure the safety and reliability of electric appliance wire connection, the electric hydraulic clamp crimping wire terminal is widely applied in the fields of railway vehicle manufacturing industry, power transmission and distribution room engineering and the like, the crimping terminal is in a handheld and visual correction mode for adapting to the change of operation environment positions and construction space, but the indentation positions of the terminal have larger differences along with the deformation of the crimping process of the terminal and the construction state of an operator, the terminal with the deviation of the indentation positions only cuts part of length wires and then is crimped again, and the crimping terminal is shortened in wire calibration length, the quality of the wiring of subsequent equipment is affected, and risks are hidden. On one hand, the crimping method brings uncertainty to the wire crimping standard and the wiring quality of subsequent equipment; on the other hand, the waste of the terminal machine leads causes great waste of the production and manufacturing costs.
In the prior art, the terminal crimping is mainly divided into three parts, namely a hydraulic clamp head 13, a lower jaw 9 and an upper jaw 12, as shown in fig. 1 and 2; the lower jaw 9 and the upper jaw 12 are fixed through a hydraulic clamp head 13, the hydraulic clamp head 13 is operated by a human hand to control an electric hydraulic clamp switch to be turned off, and hydraulic pipe pressure drives the lower jaw 9 and the upper jaw 12 connected with the hydraulic clamp head 13 to squeeze and shape the terminal 10 and the lead 11. The final terminal 10 indentation is required to ensure that the terminal and wire crimping stress meets the requirements, and the upper jaw indentation and the lower jaw indentation are required to be centered on the whole terminal 10 crimping surface in the X axis direction and vertical to the terminal crimping surface in the Y axis direction.
The construction steps in the prior art are that an operator manually controls the wires to enter the terminal until the wire observation holes are clearly visible, the wire core overflows, the upper jaw and the lower jaw are pre-pressed to the terminal crimping surface to fix the terminal, and meanwhile, the wires are continuously extruded to ensure that the wires meet the requirements of 1/2 positions in the X-axis direction and the Y-axis direction and the wiring surface are perpendicular.
Whereas the positioning steps of the prior art crimping process mainly comprise:
firstly, selecting upper and lower jaws corresponding to the types of crimping terminals to be installed in a hydraulic clamp head, deeply stripping the wire insulation skin terminal, pushing the stripped bare wire into the terminal by an operator until the wire observation hole clearly sees overflow of the wire core, and keeping a distance of 1-2mm between the root of the terminal and the wire insulation skin;
secondly, penetrating the terminal from the X-axis direction to the positions of the upper jaw and the lower jaw of the hydraulic clamp head, and visually observing the 1/2 position, the 1/3 position and the 2/3 position of the terminal crimping surface and the X-axis direction of the upper jaw and the lower jaw by an operator, wherein the terminal wiring surface is vertical to the Y-axis direction of the upper jaw and the lower jaw;
thirdly, the operator operates the electric button of the hydraulic pliers until the upper jaw and the lower jaw are pressed and connected with the lead until the pressure value is automatically released.
Through careful study of the positioning process in the prior art, the positioning process in the prior art mainly has the following defects:
1. in the crimping positioning, an operator is required to continuously apply the axial stress of the terminal and the wire X, so that the terminal and the bare wire are ensured to meet the technological requirements of the terminal crimping surface and the upper jaw and the lower jaw in the X-axis direction by 1/2 position, 1/3 position and 2/3 position, and meanwhile, the crimping surface and the Y-axis are ensured to be kept vertical, the requirement on the skill level of staff is high, and the accurate positioning is difficult to realize.
2. If the terminal is fixed at the process positions of the upper jaw and the lower jaw in advance, the problem of burrs and nest cores of the wire core is easily caused by reinsertion of the bare wire, and quality hidden trouble is brought to the quality of the crimping terminal.
3. The crimping process causes deformation of the terminal and the bare conductor, causes displacement of the crimping position, and only depends on manpower to meet the technological requirements, so that the molding quality qualification rate of the crimping terminal is low.
Accordingly, based on the above technical problems, a person skilled in the art needs to develop a positioning device and a positioning method for an electro-hydraulic clamp crimping terminal.
