Description

Technical Field

[0001] The utility model relates to the technical field of stamping equipment, in particular to a multifunctional wire harness terminal stamping fixture. Background Technique

[0002] With the rapid development of the electronics industry and the expansion of the market, the electrical system has become increasingly powerful, and various electrical appliances with different characteristics have emerged continuously. Their requirements for the electrical performance of wire harnesses are also getting higher and higher. As the connection point of the wire harness, the quality of the connection terminal directly affects whether the wire harness can be used normally. During processing, first, the terminal is sleeved on the end of the wire harness, and then the needle inside the terminal pierces the wire harness skin through stamping. Then, a metal protective shell is sleeved outside the terminal, and the metal protective shell is pressed onto the connection between the terminal and the wire harness through stamping to form a stable connection between the terminal and the wire harness. However, the existing two stamping operations need to be carried out on two stamping devices, which is relatively inconvenient to operate. Content of the Utility Model

[0003] To overcome the above disadvantages, the purpose of the utility model is to provide a multifunctional wire harness terminal stamping fixture, which integrates the two stamping operations on one machine and improves the operation convenience.

[0004] To achieve the above purpose, the technical scheme adopted by the utility model is: a multifunctional wire harness terminal stamping fixture, including

[0005] A machine table, on which a base is arranged along the vertical direction;

[0006] A stamping assembly, arranged on the side of the base facing the human body, which includes a first stamping part and a second stamping part arranged in parallel. The first stamping part includes a first lower die base and a first upper die base, and the second stamping part includes a second lower die base and a second upper die base. The first lower die base and the second lower die base are fixedly connected to the machine table, and the first upper die base and the second upper die base are fixedly connected to a connecting plate, and the connecting plate can drive the first upper die base and the second upper die base to move respectively towards or away from the first lower die base and the second lower die base under the action of a stamping driving part;

[0007] A limiting assembly, including a first limiting part and a second limiting part. The first limiting part is used to limit the moving direction of the connecting plate, and the second limiting part is used to limit the moving direction of the first upper die base and the second upper die base.

[0008] The beneficial effect of the wire harness terminal stamping fixture of the utility model lies in:

[0009] In the stamping assembly, the first stamping part and the second stamping part are integrated on the base, realizing two operations of piercing and crimping the wire harness terminals simultaneously with one device, which improves the operation convenience. Among them, the connecting plate is driven by a stamping driving part to move, so as to drive the first upper die base and the second upper die base to move simultaneously towards or away from the first lower die base and the second lower die base, so that in a single stroke of the stamping driving part, the processing of two wire harness terminals can be realized (one wire harness terminal is subjected to piercing stamping under the action of the first stamping part, and the other wire harness terminal is subjected to protective shell crimping under the action of the second stamping part); furthermore, the moving direction of the connecting plate is restricted by the first limiting part, and the moving directions of the first upper die base and the second upper die base are restricted by the second limiting part, so that during the process of the first upper die base and the second upper die base moving along with the connecting plate, they can be subjected to multiple limitings, thereby ensuring the stamping accuracy.

[0010] Furthermore, a terminal receiving groove for receiving the terminal is integrally provided at the upper end of the first lower die base, and a first stamping head that can be embedded into the terminal receiving groove is integrally provided at the lower end of the first upper die base; when the wire harness with the terminal sleeved is placed into the terminal receiving groove, the first stamping head pushes the terminal downward, so that the needle in the terminal can pierce the wire harness skin downward. The terminal can be positioned through the terminal receiving groove, and then the terminal can be pushed by the first stamping head, so that the terminal can squeeze the wire harness downward, and further the needle in the terminal pierces the wire harness skin.

[0011] Furthermore, the terminal receiving groove is a trapezoidal groove with a wider upper part and a narrower lower part, and the width of the bottom of the trapezoidal groove is adapted to the width of the terminal. This is beneficial for the terminal to enter the terminal receiving groove.

When the wire harness is located in the wire harness positioning groove, the protective shell sleeved at the connection between the wire harness and the terminal is located outside the wire harness positioning groove. At this time, through the downward pressing of the second stamping head, the second stamping head can drive the protective shell to be crimped onto the wire harness.

[0013] Furthermore, the first limiting part includes a limiting sliding groove opened on the base, and a pair of L-shaped limiting blocks are symmetrically provided at the upper end of the limiting sliding groove. An upper sliding groove communicating with the limiting sliding groove is defined between the pair of L-shaped limiting blocks; the connecting plate can move up and down along the limiting sliding groove, and the stamping driving part passes through the upper sliding groove and is connected to the connecting plate. The moving direction of the connecting plate can be limited by the limiting sliding groove, and the moving direction of the stamping driving part can be limited by the upper sliding groove.

The piston rod of the cylinder extends into the upper sliding groove and is connected to the piston connecting column. The lower end of the piston connecting column is connected to the connecting plate, and the upper end can abut against the L-shaped limiting block.

[0015] Furthermore, the second limiting portion is arranged corresponding to the first stamping portion and the second stamping portion one by one. It includes an upper limiting plate and a lower limiting plate. The upper limiting plate is fixedly connected to the connecting plate, and the lower limiting plate is fixedly connected to the machine table. Moreover, the upper limiting plate and the lower limiting plate are arranged vertically, and one end thereof facing the first stamping portion or the second stamping portion can be attached to the first stamping portion or the second stamping portion. Through the arrangement of the upper limiting plate and the lower limiting plate, the movement of the first stamping portion and the second stamping portion can be guided.

[0016] Furthermore, a transparent protective cover is sleeved outside the base. An operation window is opened on one side of the transparent protective cover facing the human body, and the wire harness can enter the first stamping portion or the second stamping portion from the operation window. The transparent protective cover can not only play a role in safety protection but also facilitate observing the working process of the stamping assembly.

[0033] See the attached Figures 1-4 As shown, a multifunctional wire harness terminal stamping jig of the present utility model includes a machine table 1, a stamping assembly, and a limiting assembly. Among them, a base 2 arranged in the vertical direction is provided on the machine table 1. The stamping assembly is arranged on the side of the base 2 facing the human body, and it includes a first stamping part 3 and a second stamping part 4 arranged in parallel. The first stamping part 3 includes a first lower die base 31 and a first upper die base 32, and the second stamping part 4 includes a second lower die base 41 and a second upper die base 42. The first lower die base 31 and the second lower die base 41 are fixedly connected to the machine table 1, and the first upper die base 32 and the second upper die base 42 are fixedly connected to the connecting plate 5. Moreover, the connecting plate 5 can drive the first upper die base 32 and the second upper die base 42 to move respectively in the direction of approaching or departing from the first lower die base 31 and the second lower die base 41 under the action of the stamping driving part 6. The limiting assembly includes a first limiting part and a second limiting part. The first limiting part is used to limit the moving direction of the connecting plate 5, and the second limiting part is used to limit the moving direction of the first upper die base 32 and the second upper die base 42.

[0034] In the stamping assembly, the first stamping part 3 and the second stamping part 4 are integrated on the base 2, realizing two-step operations of piercing and crimping the wire harness terminals on one device, which improves the operation convenience. Among them, the connecting plate 5 is driven by the stamping driving part 6 to move, so as to drive the first upper die base 32 and the second upper die base 42 to move simultaneously in the direction close to or away from the first lower die base 31 and the second lower die base 41, so that in a single stroke of the stamping driving part 6, the processing of two wire harness terminals can be realized (one wire harness terminal is subjected to piercing stamping under the action of the first stamping part 3, and the other wire harness terminal is subjected to protective shell crimping under the action of the second stamping part 4); furthermore, the moving direction of the connecting plate 5 is restricted by the first limiting part, and the moving directions of the first upper die base 32 and the second upper die base 42 are restricted by the second limiting part, so that when the first upper die base 32 and the second upper die base 42 move along with the connecting plate 5, they can be subjected to multiple limitings, thereby ensuring the stamping accuracy.

[0035] In some embodiments, referring to the attached Figures 2-3 As shown, a terminal receiving groove 311 for receiving the terminal is integrally provided at the upper end of the first lower die base 31, and a first stamping head 321 that can be embedded into the terminal receiving groove 311 is integrally provided at the lower end of the first upper die base 32. When the wire harness with the terminal sleeved is placed in the terminal receiving groove 311, the first stamping head 321 pushes the terminal downward, so that the needle in the terminal can pierce the wire harness skin downward. The terminal can be positioned through the terminal receiving groove 311, and then through the pushing of the first stamping head 321 on the terminal, the terminal can squeeze the wire harness downward, so that the needle in the terminal pierces the wire harness skin.

[0036] Furthermore, the terminal receiving groove 311 is a trapezoidal groove with a wider upper part and a narrower lower part, and the width of the bottom of the trapezoidal groove is adapted to the width of the terminal, which is beneficial for the terminal to enter the terminal receiving groove 311.

When the wire harness is located in the wire harness positioning groove 412, the protective shell sleeved at the connection of the wire harness and the terminal is (circumferentially along the wire harness) located outside the wire harness positioning groove 412. At this time, since the second stamping head 421 can be sleeved on the wedge-shaped seat 411, as the second stamping head 421 presses downward, the second stamping head 421 can drive the protective shell to be crimped onto the wire harness.
