Description

Technical Field

[0001] The invention belongs to the technical field of wire production, and in particular relates to a wire terminal-threading auxiliary device. Background Art

[0002] At present, in the production process of wires, after the wires are peeled, the copper wires expand slightly. After the two wires are combined, it is difficult to insert them into the round terminal. After the wires are inserted into the terminal and crimped, the number of copper wires in the wires is close to that of the round terminal. If the difference is too large, it is easy to be crimped and deformed, and the pulling force does not meet the requirements. It is difficult to assemble if the difference is small. At present, there is no suitable equipment. The general operation method is to manually compress or tighten the expanded copper wires and then align them into the terminals. During the terminal alignment process, the staff needs to operate with both hands and can only rely on visual alignment. The operation is highly repetitive and labor-intensive, and the efficiency is low. For wires with smaller diameters, the operation of inserting the terminals is more difficult, which seriously affects the production efficiency. If the wire is not qualified when inserted into the terminal, it will cause poor subsequent crimping effect and affect product quality.

[0022] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0023] like Figures 1 to 3 As shown, the wire terminal auxiliary device includes a base plate 1, a first base 2 is provided on the base plate 1, a second base 3 is provided on one side of the first base 2, the first base 2 and the second base 3 are both detachably connected with a pressure block 4, and the pressure blocks 4 are arranged opposite to each other; the pressure block 4 on the second base 3 is connected with a clamping mechanism.

[0024] The base is used to install the pressing block 4, and the pressing block 4 is detachable, which is convenient for switching according to needs. The relatively arranged pressing block 4 is used to squeeze the expanded copper wire on the conductor, so that the copper wire is gathered to the required size for easy insertion of the terminal. At the same time, the pressing block 4 clamps the conductor and fixes it stationary. The operator only needs to hold the terminal and place it on one end of the squeezed copper wire of the conductor to insert the copper wire of the conductor, thus completing the terminal insertion process. Compared with the traditional two-handed operation and visual alignment method, the operation difficulty is low and the efficiency is greatly improved.

[0025] like Figure 1 As shown, the clamping mechanism includes a cylinder 5, a guide rail 7 is fixedly connected to the bottom plate 1, the cylinder 5 is fixedly connected to one end of the guide rail 7, a slider 8 is provided on the guide rail 7, the slider 8 cooperates with the guide rail 7, the second base 3 is arranged on the slider 8, and the piston rod 6 of the cylinder 5 is connected to the slider 8. The cylinder 5 provides power for the pressing block 4 to squeeze the wire, the slider 8 and the guide rail 7 ensure the linearity of the power transmission of the piston rod 6, and the piston rod 6 pushes the slider 8 to contact the two pressing blocks 4 to form a squeezing effect; using the cylinder 5 as the power source of the pressing block 4 is low in cost and easy to arrange, and the switch of the cylinder 5 can be set at the bottom of the workbench or on the ground, which is convenient for the operator to control by foot.

[0026] like Figure 4As shown, a pressing groove 14 is provided at the end of the pressing block 4, and the pressing groove 14 is arranged horizontally, and a guide opening 15 is provided at the end of the pressing groove 14. The relatively arranged pressing grooves 14 form a cylindrical space after contact. Through the extrusion of the pressing groove 14, the expanded copper wire at the end of the wire is compressed to form a regular cylindrical shape, which is more convenient for inserting the terminal. The guide opening 15 is provided at the end of the pressing groove 14 as the corresponding area of ​​the terminal connection end. The guide opening 15 can facilitate the initial insertion of the terminal into the wire for a certain distance without difficulty in alignment, thereby improving the operation efficiency. When the slider 8 moves to the maximum distance, the ends of the two pressing blocks 4 are in contact, the wire is located in the pressing groove 14, and the pressing groove 14 squeezes the copper wire of the wire into shape. The push of the slider 8 by the cylinder 5 eliminates the operation of manually tightening or screwing the copper wire. Combined with the shaping effect of the pressing groove 14 on the copper wire of the wire and the alignment effect of the guide opening 15 on the terminal, it is ensured that the terminal is qualifiedly inserted into the wire.

[0027] like Figure 2 As shown, an anti-collision structure is also provided on the bottom plate 1 at one side of the guide rail 7, and the anti-collision structure includes a mounting plate 11, a baffle 12 is provided on the mounting plate 11, a baffle 13 is fixedly connected to one side of the slider 8, the baffle 13 is an L-shaped structure, and the baffle 12 is located at one side of the end of the baffle 13. The end of the L-shaped baffle 13 corresponds to the baffle 12 in the transverse direction, and in order to prevent the cylinder 5 from exerting too much contact force on the pressure block 4, the baffle 12 is set to limit the maximum moving distance of the slider 8 to prevent the pressure block 4 from being damaged by collision.

[0028] like Figure 1 As shown, bolt holes 9 are provided on the sides of the first base 2, the second base 3 and the pressing block 4, and mounting grooves 10 are provided on the upper ends of the first base 2 and the second base 3. One end of the pressing block 4 is located in the mounting groove 10, and the other end extends out of the mounting groove 10. One end of the pressing block 4 located in the mounting groove 10 is a square structure. The mounting groove 10 is located at the upper ends of the above-mentioned two bases. The assembly and disassembly operations of the pressing block 4 are located in a direction perpendicular to the bottom plate 1, and will not cause spatial interference to other structures. One end of the pressing block 4 is designed to be square, which can form a four-surface contact limiting effect with the mounting groove 10, and has higher stability. When assembling and disassembling the pressing block 4, the end of the pressing block 4 located outside the mounting groove 10 can be directly taken, and no inconvenience in assembly and disassembly will be caused. For wires of different diameters, it is only necessary to replace the pressing block 4 with a pressing groove 14 of corresponding size, which greatly reduces the difficulty of operation and solves the problem that it is difficult to pass the terminal for small diameter wires.

[0029] like Figure 3 As shown, the depth of the installation groove 10 is equal to the height of the pressing block 4, and the upper end surfaces of the first base 2, the second base 3 and the pressing block 4 are in the same plane. To ensure that the pressing block 4 is installed in the correct position, the sizes of the installation groove 10 and the pressing block 4 are adapted so that the upper end surfaces of the two are coplanar after installation, and the bolt holes 9 of the base and the pressing block 4 are aligned, so that the bolts can be used to lock the pressing block 4.

[0030] like Figure 2As shown, the guide rail 7, the first base 2 and the second base 3 are all provided with connecting holes 17. The components on the bottom plate 1 are detachable for easy maintenance. At the same time, a protective cover can be installed outside the bottom plate 1 to isolate the operator's hands and achieve a protective effect.

[0031] like Figure 1 As shown, the first base 2 is a T-shaped structure. The first base 2 is a pressure-bearing side, and is designed to be T-shaped to improve its stability and provide a location for the connection hole 17 to be set.

[0032] like Figure 2 As shown, the end of the bottom plate 1 is provided with a fixing hole 16. All components in the device are mounted on the bottom plate 1, the structure is compact, and the space occupied is small. The whole device can be directly installed on the existing workbench without affecting the operation of the original mechanism on the workbench.

[0033] The method of using the device is as follows: the chief person peels off the outer sheath of the wire to expose the copper wire, puts the copper wire parts of the two wires together and places them in the pressing groove 14 of the pressing block 4 on the first base 2, starts the switch, and the cylinder 5 starts to move the slider 8 along the guide rail 7. The slider 8 drives the second base 3 to move. The two pressing blocks 4 contact and squeeze and deform the copper wire at the head of the wire, so that the shape of the expanded and deformed copper wire is smaller than the diameter of the circular terminal. Then, the connecting end of the terminal is inserted into the copper wire along the guide port 15. After the cylinder 5 is reset, the wire is taken out to complete the terminal insertion process.

[0034] The auxiliary device for wire terminal insertion replaces the traditional manual squeezing and visual alignment operation mode, simplifies the operation steps, reduces the labor intensity of personnel, and can form multiple wires into regular shapes through the squeezing of the wire by the pressing block 4 and the shaping effect of the pressing groove 14, greatly reducing the difficulty of terminal insertion alignment and ensuring the subsequent crimping quality; for wires of different diameters, it is only necessary to replace the pressing block 4 with the corresponding size of the pressing groove 14 to meet the terminal insertion requirements; it also has the advantages of simple structure, detachable parts, low cost and high efficiency.

[0035] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above-mentioned concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
