Description

Technical Field

[0001] This utility model belongs to the field of wire harness terminal stamping technology, and in particular relates to an instrument wire harness terminal stamping machine. Background Technology

[0002] Instrument wiring harness terminal stamping machine is a mechanical device specially used for manufacturing and processing instrument wiring harness terminals in the automotive, electronics and other industries. This equipment connects the terminals to the ends of the wiring harness through a stamping process, which facilitates the subsequent connection of the wiring harness to the instrument.

[0003] Traditional instrument wiring harness terminal punching machines typically use a semi-automatic method for punching. Operators need to put the end of the wiring harness onto the terminal, place the connection point between the two on the lower punch head, and then use the upper punch head to punch downwards to connect the terminal and the wiring harness. However, the traditional upper and lower punch heads only use mutual squeezing to connect the wiring harness and the terminal. This method is difficult to make the terminal and wiring harness secure, and the terminal and wiring harness are prone to falling off during subsequent use. Utility Model Content

[0004] The purpose of this utility model is to provide an instrument wiring harness terminal punching machine. By setting a punching mechanism, specifically during the punching process, the control cylinder is started, driving the lifting seat to move downward, so that the upper punch moves downward along with it. The arc groove will contact the metal on the terminal and push the metal sheet to bend. Then, the inner protrusion is used to squeeze the metal sheet, so that the terminal can be rolled and embedded into the wiring harness, thereby firmly connecting the terminal and the wiring harness and improving the locking effect. This solves the problem that the upper and lower punches only use mutual squeezing to connect the wiring harness and the terminal. This method is difficult to secure the terminal and the wiring harness, and the terminal and the wiring harness are prone to falling off during subsequent use.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an instrument wiring harness terminal punching machine, comprising a base, a plurality of columns fixedly connected to the top of the base, a fixed seat fixedly connected to the top of each column, a cylinder fixedly connected to the top of the fixed seat, and lifting seats slidably connected to the two columns located at the front, and further comprising: A stamping mechanism is provided in front of a lifting base. The stamping mechanism includes a mounting base that is screwed onto the lifting base. An upper punch is provided inside the mounting base. A mounting plate is positioned on the top of the base. A lower punch and an adjusting block are provided on the top of the mounting plate. The lower punch is screwed onto the left side of the adjusting block. A positioning groove is provided on the top of the lower punch. An arc-shaped groove is provided on the bottom of the upper punch. An inner protrusion is fixedly connected to the top of the arc-shaped groove. The upper punch bottom is adapted to the lower punch top. A terminal is placed in the positioning groove on the lower punch. The signal line of the foot switch is connected to the input port of the controller. A signal line is led out from the output port of the controller and connected to the coil of the solenoid valve. The air outlet of the solenoid valve is connected to the air inlet of the cylinder through an air pipe. The air outlet of the cylinder is connected to an external exhaust device or the atmosphere through an air pipe.

[0006] Furthermore, each of the four corners of the upper punch is fixedly connected to a positioning shaft, and a magnetic block is embedded in the top inner side of the mounting base. The positioning shaft is positioned and inserted into the mounting base. The positioning shaft is used to position the upper punch during installation. The upper punch and the mounting base are locked together with screws. When the upper punch is positioned and inserted into the mounting base through the positioning shaft at the top, the magnetic block will attract and fix the upper punch by magnetic attraction, making it convenient for the operator to lock the upper punch onto the mounting base with screws.

[0007] Furthermore, the mounting plate has slots on both the left and right sides, and a bolt is inserted into each slot. A square block is threaded to the bottom of the bolt. A limiting groove is formed on the top of the base, and the square block is slidably connected in the limiting groove. Two positioning blocks are fixedly connected to the top of the base, and the mounting plate is positioned and inserted into the two positioning blocks. Since the square block is square, the bolt will not cause the square block to rotate when it rotates, allowing the square block to move smoothly upward or downward. The bolt and the square block are used to lock and fix the mounting plate. The square block is square and fits the inner wall of the limiting groove.

[0008] Furthermore, two positioning plates are fixedly connected to the right side of the lower punch, and a protrusion is fixedly connected to the left side of the lower punch. The positioning plates are inserted into the adjusting block. The positioning plates are used to position the lower punch during installation. The terminal is placed in the positioning groove, and the protrusion supports and positions the terminal.

[0009] Furthermore, a fixed frame is provided in front of the lower punch, and the bottom of the fixed frame is fixedly connected to the top of the base. Fixed block one and fixed block two are fixedly connected to the front of the adjusting block. Fixed block three is provided on the right side of fixed block two. The bottom of fixed block three is fixedly connected to the top of the base. Bolt three is threaded inside fixed block three. Two convex plates two are fixedly connected to the left side of bolt three. When bolt three rotates, it will drive the adjusting block to move to the left or right through the two convex plates two.

[0010] Furthermore, the fixing block 1 is internally threaded with bolt 2, and bolt 2 is fixedly connected to the bottom of cam 1. The fixing frame has a straight groove, and bolt 2 is located inside the straight groove on the fixing frame. The top of cam 1 contacts the top of the inner side of the fixing frame. The two cams 2 are respectively located on the left and right sides of fixing block 2. When bolt 2 is tightened, it will drive cam 1 to move together. When cam 1 contacts the fixing frame, it will lock the adjusting block. When cam 1 moves away from the fixing frame, the adjusting block will loosen.

[0011] Furthermore, a limiting groove is formed on the top of the mounting plate, and a slider is fixedly connected to the bottom of the adjusting block. The slider is slidably connected inside the limiting groove, and the bottom of the adjusting block contacts the top of the base. When the adjusting block moves, the slider will slide in the limiting groove, making the movement of the adjusting block more stable.

[0012] This utility model has the following beneficial effects: This utility model incorporates a stamping mechanism. Specifically, during the stamping process, a control cylinder is activated, causing the lifting seat to move downwards. This causes the upper punch to move downwards as well, resulting in the arc-shaped groove contacting the metal on the terminal and pushing and bending the metal sheet. The inner protrusion then compresses the metal sheet, allowing the terminal to be rolled and embedded into the wire harness. This securely connects the terminal and the wire harness, improving the locking effect.

[0013] This utility model incorporates an adjustment block. Specifically, after the upper and lower punches are installed, rotating the bolt three-faced plate two with a hex wrench moves the fixing block two to the left or right, which in turn moves the adjustment block, thereby fine-tuning the lower punch and aligning it with the upper punch. Even if different sizes of upper and lower punches are replaced, they will always be aligned, improving the connection effect between the wire harness and the terminal.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Then, the operator uses the foot switch to control the cylinder 121 to start, which drives the lifting seat 13 to move downward, causing the upper punch 22 to move downward as well. The arc groove 222 will then contact the metal on the terminal 244 and push the metal sheet to bend. Then, the inner protrusion 223 will squeeze the metal sheet, so that the terminal can be rolled and embedded into the wire harness, thereby firmly connecting the terminal and the wire harness and improving the locking effect. Then, the foot switch is stopped, and the cylinder 121 will drive the mounting seat 21 to return to its original position.
