Technical Field
[0001] The utility model relates to a connector production tool, in particular to a tongue pressing hole closing tool. Background Art
[0002] Among existing connector jack structures, the tongue-tightening hole is widely used in high-density micro-circular electrical connectors due to its simple structure, which facilitates miniaturization, prevents over-insertion of pins, and offers high reliability. The quality of the tongue-tightening hole's closing directly affects the smooth transmission of current or signals throughout the entire circuit. However, manual closing with closing pliers is cumbersome, time-consuming, and labor-intensive, and cannot guarantee consistent closing of the jack each time. Therefore, a tooling solution is urgently needed to ensure convenient and consistent closing of the tongue-tightening hole. Summary of the Invention
[0003] The utility model provides a tongue-pressing hole closing tool with a simple structure, convenient closing operation, stable closing quality and good consistency.
[0004] The technical solution adopted by the utility model is: a tongue pressing hole closing tooling, characterized in that: it includes a punching head and a positioning block, the left side of the upper end of the positioning block is a positioning area, the middle part is a punching area, and the right side is an alignment area, a plurality of lower arc-shaped placement grooves along the left and right directions for placing the non-closing part of the tongue pressing hole are arranged in front and behind the left side of the upper end of the positioning block, a crimping block is crimped on the left side of the positioning block, and a plurality of upper arc-shaped crimping grooves are arranged on the lower end of the crimping block corresponding to the lower arc-shaped placement grooves, and the middle part of the upper end of the positioning block is a corresponding part under the punching head to support the closing part of the tongue pressing hole The supporting plane of the position, the left and right guides on the right side of the upper end of the positioning block are connected with the adjustment block, the adjustment block faces left and corresponds to the axial outer end of the closing part of the tongue pressing hole, two adjustment tracks in the upper and lower directions are respectively set at the front and rear positions on the left side of the adjustment block, an adjustment block is set in the adjustment track, an adjustment screw is connected on the adjustment block, the upper end of the adjustment screw is connected to the external adjustment handwheel on the adjustment block, the adjustment block extends to the left to set a connecting column on the adjustment track, and a positioning wire that passes through the opening of the closing part of the tongue pressing hole is horizontally connected between the connecting columns of the two adjustment blocks.
[0005] The left side and / or the front side and / or the rear side of the crimping block and the positioning block are clamped and connected via clamping hooks.
[0006] The left side of the upper arc-shaped pressing groove of the pressing block is provided with a groove bottom surface which abuts against the outer end of the non-closed portion of the pressing tongue hole.
[0007] The positioning wire is connected to any connecting column via a spring.
[0008] The spring is provided with a spirit level.
[0009] The upper ends of the two adjusting screw rods are driven by driving rods through two sets of bevel gear sets to rotate synchronously, and the driving rods are externally connected to the adjusting handwheel.
[0010] The utility model is used for closing operation, and multiple tongue pressing holes are placed on the positioning block, and the non-closing part of the tongue pressing holes is placed in the lower arc-shaped placement groove on the left side. The closing part of the tongue pressing holes is supported on the middle supporting plane, and the outer ends of the closing parts of the tongue pressing holes are adjusted to be aligned by pushing the adjustment block along the right guide. At the same time, the positioning wires between the connecting columns of the two adjustment blocks are synchronously inserted into the openings of the closing parts of the tongue pressing holes when the outer ends of the closing parts of the tongue pressing holes are aligned. Then, the two adjustment blocks are driven to rise and fall by adjusting the two adjustment screw rods, so that the positioning wire adjustment lifting support is placed below the inner wall of the opening of the closing part of all the tongue pressing holes. Combined with the spring and the spirit level, it is ensured that the openings of the closing parts of the tongue pressing holes are uniformly adjusted to be horizontal, and the punching head corresponds to the opening of the closing part of the tongue pressing holes, thereby realizing batch stamping and closing operation. The closing operation is convenient, the closing quality is stable, and the consistency is good. The positioning ribbon spring can ensure the tension of the positioning wire and the stability and consistency of the stamping opening during the entire stamping process; before stamping, the punching head presses down and fixes the non-closed part of the tongue hole through the crimping block, which is beneficial to the stability of the stamping operation. When the adjustment block pushes the outer end of the closed part of the tongue hole to align, the outer end of the non-closed part of the tongue hole rests on the bottom surface of the arc-shaped crimping groove on the crimping block, which helps to position the alignment accuracy and the stability of the stamping operation; the crimping block can be positioned and crimped on the positioning block with a clamping hook, which is beneficial to the stability of the stamping operation.
