Description

Technical Field

[0001] This utility model belongs to the field of terminal wire crimping technology, and specifically relates to a terminal wiring crimping mechanism. Background Technology

[0002] In many fields such as electrical equipment manufacturing and automotive wiring harness production, the crimping of wire harnesses to copper terminals is a crucial process. Reliable crimp connections ensure stable transmission of electrical signals and safe power delivery, playing a decisive role in product performance and quality.

[0003] Traditional terminal crimping work largely relies on manual operation. Operators must manually insert and mate the copper terminals and copper wires, then manually move the wire harness and use simple crimping tools to perform multiple crimps at different locations. However, with the continuous expansion of industrial production scale and the increasing demands for product quality, this traditional manual crimping method has gradually revealed many drawbacks and can no longer meet the needs of modern production.

[0004] When manually moving the wire harness to perform multiple crimps, it is difficult to ensure that the crimping position is accurate and consistent each time. Due to the lack of precise positioning and control, crimping at different positions may be offset, resulting in uneven contact area between the copper terminal and the copper wire. This affects the stability of the electrical connection, increases contact resistance, and may lead to safety hazards such as overheating and short circuits. Manual operation makes it difficult to precisely control the crimping force. Different operators have different strengths and operating habits, and even the same operator may experience fluctuations in force at different times. Insufficient crimping force will result in a weak connection between the copper terminal and the copper wire, making it easy to loosen; excessive crimping force may damage the copper wire or copper terminal, reducing the mechanical strength and electrical performance of the crimped area. Manually inserting and fitting copper terminals and copper wires and moving the wire harness one by one to perform multiple crimps requires a lot of time and effort. Moreover, the operator is prone to fatigue during long periods of repetitive operation, further reducing work efficiency. Manual operation requires the operator to maintain the same posture for a long time and frequently perform actions such as inserting, unplugging, and moving the wire harness, which can easily lead to physical fatigue and injury, especially in the hands, shoulders, and waist. Prolonged exposure to such high-intensity labor can negatively impact the health of operators, increasing human resource management costs and labor risks for businesses. Manual crimping is typically only suitable for wire harnesses and copper terminals of specific sizes and specifications. When handling products of different sizes, operators need to readjust their methods and tools, increasing the difficulty of operation and potentially affecting crimping quality due to improper adjustments. Furthermore, for copper terminals and wire harnesses with special shapes or complex structures, effective crimping is often difficult to achieve manually.

[0005] In view of this, we propose a terminal crimping mechanism to solve the above problems. Utility Model Content

[0027] 2. Different wire harnesses vary in diameter and material.

The terminal crimping assembly 2 crimps the copper wire 6 and copper terminal 5. The wire harness clamping mechanism 1 pushes the wire harness 4 to move horizontally, so as to cooperate with the terminal crimping assembly 2 to crimp the copper wire 6 and copper terminal 5 at multiple points.

[0043] This terminal crimping mechanism rationally combines the wire harness clamping mechanism 1, the terminal crimping assembly 2, and the terminal clamping mechanism 3, possessing multiple functions such as clamping, conveying, lifting, and crimping. The various mechanisms work together to crimp the copper wires 6 and copper terminals 5 on the wire harness 4. Furthermore, the wire harness clamping mechanism 1 pushes the wire harness 4 to move horizontally, cooperating with the crimping assembly to perform multiple crimps. Its main advantages are:

By replacing different upper clamps A11 and lower clamps A12, wire harnesses 4 of various sizes can be stably clamped and positioned, expanding the applicability of the mechanism and improving the versatility of the equipment. The clamps may wear or be damaged during long-term use; the detachable design makes clamp replacement more convenient and quick, without needing to replace the entire wire harness clamping mechanism 1, reducing maintenance costs and downtime. Using specially adapted clamps for different sizes of wire harnesses 4 can better ensure the clamping accuracy of the wire harnesses 4 and avoid problems such as insecure clamping or damage to the wire harnesses 4 due to incompatibility between the clamps and the wire harnesses 4.

[0055] By replacing different upper pressure heads 21 and lower pressure heads 22, the crimping of wire harnesses 4, copper terminals 5, and copper wires 6 of different sizes can be adapted.

[0056] Different sizes of wire harnesses 4, copper terminals 5, and copper wires 6 require different crimping forces and shapes during crimping. Changing the upper crimp head 21 and lower crimp head 22 allows for adjustments based on the specific object being crimped, ensuring the crimping effect meets requirements and improving crimping quality and product consistency. The crimp head is a vulnerable component in the crimping process and will wear down with prolonged use. The detachable design facilitates timely replacement of worn crimp heads, preventing impact on crimping quality due to head wear and extending the lifespan of the entire terminal wiring crimping assembly 2. When crimping products of different specifications is required, only the crimp head needs to be replaced, eliminating the need to purchase new crimping equipment, significantly reducing equipment procurement costs for enterprises.

[0057] The terminal clamping mechanism 3 includes a detachable and replaceable upper chuck D31 and lower chuck D32, a lifting hydraulic cylinder D33, a descending air cylinder D34, and a servo screw linear module D35.

The lower chuck D32 is inserted into the inside of the semi-circular plug-in groove D38, and the top of the lower chuck D32 is limited by the limiting plates D310 and locked and positioned on the plug-in base D39 by the locking bolts.

[0059] The T-shaped block D311, which is integrated on the top of the upper chuck D31, is inserted into the plug block D312 at the bottom of the piston rod of the lower cylinder D34, and the T-shaped block D311 is locked and fixed to the plug block D312 by locking bolts; the lower cylinder D34 is fixed on the bracket D313, and the bracket D313 is fixed on the mounting base D37.

[0060] By changing different lower clamps D32 and upper clamps D31, the clamping of wire harnesses 4 of different sizes can be adapted.

[0061] The bracket D313 is equipped with a bracket E314, and the top of the bracket E314 is equipped with a limiting groove 315 for fitting and limiting the insertion of the copper terminal 5.

[0062] Similar to the wire harness clamping mechanism 1, copper terminals 5 of different sizes require different specifications of clamps for clamping and positioning. By replacing the upper clamp D31 and the lower clamp D32, stable clamping of copper terminals 5 of various sizes can be ensured, improving the mechanism's compatibility with different products. Clamps may wear or be damaged after frequent use; the detachable clamp design makes replacement simpler and more efficient, reducing equipment maintenance time and costs.

[0063] The limiting groove 315 on the top of the bracket E314 provides an accurate insertion position for the copper terminal 5, ensuring that the copper terminal 5 is accurately positioned when inserted with the copper wire 6 on the wire harness 4, avoiding poor crimping due to insertion deviation. The limiting groove 315 limits the copper terminal 5, preventing it from shaking or shifting during the lifting, translating, and other operations of the terminal clamping mechanism 3, thus ensuring the stability and reliability of the entire crimping process.
