Three-layer composite contact machine automatic alignment structure

Abstract

This invention discloses an automatic alignment structure for a three-layer composite contact machine, relating to the field of contact machine technology. The invention includes a mounting plate with three intersecting grooves—a first, a second, and a third—on one side, with decreasing depths. The first groove contains a first wire hole and a pin hole; the second and third grooves each contain a second wire hole and a third wire hole, respectively. Shearing blocks are slidably connected to each of the three grooves. A bottom mold hole is provided on the other side of the mounting plate, and a top pin is connected to it via a first driving device. A pin is connected to the bottom plate near the pin hole via a third driving device. This invention, by using three intersecting and overlapping shearing blocks, can simultaneously shear wires, solving the problems of large reciprocating stroke and poor repeatability in existing shearing mechanisms. Furthermore, the three shearing blocks ensure that the cross-sectional patterns of the joints between wire segments are different, effectively improving the joint strength between the wire segments.

Description

Technical Field

[0001] This invention belongs to the field of contact machine technology, and in particular relates to an automatic alignment structure for a three-layer composite contact machine. Background Technology

[0002] Three-layer composite contacts are made by aligning three sheared silver, copper, and copper wire segments, and then stamping them to induce significant deformation, achieving a cold solder joint. Manufacturing equipment for three-layer composite contacts often uses double or single cutters to shear the wires. However, both methods require a reciprocating shearing mechanism and alignment stamping of the sheared segments. Because double or single cutters often result in a large stroke, they can reduce the repeatability of the equipment and affect the bonding effect of the wire segments.

[0003] At the same time, these two shearing methods will also result in the shearing direction of the silver, copper and silver three-segment bonding surfaces being consistent, that is, the shearing cross-section texture of the bonding surfaces of the line segments is in the same direction, which will affect the bonding strength between the line segments and affect the overall structural strength of the three-layer composite contact.

[0004] Therefore, there is an urgent need to improve the existing three-layer composite contact machine to enhance the repeatability of the alignment between line segments and the bonding strength between line segments. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic alignment structure for a three-layer composite contact machine. By setting three intersecting and superimposed shearing blocks, the wire can be sheared simultaneously, solving the problems of large reciprocating stroke and poor repeatability of existing shearing mechanisms. At the same time, the three shearing blocks ensure that the cross-sectional textures of the joints between the wire segments are different, effectively improving the joint strength between the wire segments.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to an automatic alignment structure for a three-layer composite contact machine, comprising a base plate; a mounting plate is fixedly connected to the upper surface of the base plate; a first sliding groove, a second sliding groove, and a third sliding groove are formed on one side of the mounting plate; the depths of the first sliding groove, the second sliding groove, and the third sliding groove decrease sequentially; one end of the first sliding groove, the second sliding groove, and the third sliding groove intersects each other;

[0008] The first slide groove has a first wire hole and a pin hole on its inner side; the pin hole is located at the intersection of the first slide groove, the second slide groove and the third slide groove; the second slide groove has a second wire hole on its inner side; the third slide groove has a third wire hole on its inner side; shearing blocks are slidably connected in the first slide groove, the second slide groove and the third slide groove;

[0009] The mounting plate has a bottom mold hole on its other side that communicates with the ejector pin hole and is concentrically arranged; a fixing plate is fixedly connected to one side of the mounting plate at the bottom mold hole; a first driving device is fixedly connected to the side of the fixing plate; the first driving device is connected to an ejector pin corresponding to the bottom mold hole.

[0010] One end of the shearing block is connected to a second driving device; a shearing hole is opened on the side of the shearing block; a third driving device is fixedly connected to the upper surface of the base plate; the third driving device is located on the side close to the ejector pin hole, and the third driving device is connected to an ejector pin corresponding to the ejector pin hole.

[0011] Furthermore, the first, second, and third wire holes are all equidistant from the center of the ejector pin hole.

[0012] Furthermore, one end of the first groove has an isosceles triangular structure.

[0013] Furthermore, each of the opposite sides of the first slide groove is provided with an alignment slot; the two alignment slots correspond to the second slide groove and the third slide groove, respectively.

[0014] Furthermore, one end of the shearing block is a triangular structure that mates with the end of the first sliding groove and the alignment groove.

[0015] Furthermore, an annular cutter is fixedly connected to the inner wall of the shearing hole.

[0016] Furthermore, the side of the fixing plate is provided with wire through holes corresponding to the first wire hole, the second wire hole and the third wire hole respectively.

[0017] The present invention has the following beneficial effects:

[0018] 1. This invention features three intersecting shearing plates, which shorten the shearing stroke of the line segment, effectively ensuring the repeatability of the shearing mechanism, improving the alignment accuracy of the line segment connection, and increasing the strength of the contact connection. At the same time, the three shearing plates can perform shearing simultaneously, effectively improving production efficiency.

[0019] 2. This invention improves the alignment accuracy of line segments by setting the end of the first sliding groove and the alignment slot to define the position of each shearing block. At the same time, the three shearing blocks ensure that the shearing direction of the joint surface of the three line segments is evenly distributed, thereby effectively improving the joint strength of the line segments after stamping and ensuring the overall strength and quality of the contact.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "one end", "top", "middle", "length", "inner", "one side", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0031] Please see Figure 1 As shown, the present invention is an automatic alignment structure for a three-layer composite contact machine, including a base plate; the base plate is connected to the contact machine frame, and a mounting plate 1 is welded to the upper surface of the base plate; the mounting plate 1 is vertically arranged.

[0032] like Figure 4 As shown, the mounting plate 1 has a first sliding groove 101, a second sliding groove 102 and a third sliding groove 103 on one side; the depths of the first sliding groove 101, the second sliding groove 102 and the third sliding groove 103 decrease sequentially; the first sliding groove 101, the second sliding groove 102 and the third sliding groove 103 are all rectangular structures and intersect each other at one end; among them, one end of the first sliding groove 101 is an isosceles triangle structure, and the triangular structure facilitates position positioning.

[0033] The inner side of the first slide groove 101 is provided with a first wire hole 1011 and a pin hole 104; the pin hole 104 is located at the intersection of the first slide groove 101, the second slide groove 102 and the third slide groove 103, so that the first slide groove 101, the second slide groove 102 and the third slide groove 103 are distributed in a circle around the pin hole 104; the inner side of the second slide groove 102 is provided with a second wire hole 1021; the inner side of the third slide groove 103 is provided with a third wire hole 1031;

[0034] Among them, the first wire hole 1011, the second wire hole 1021 and the third wire hole 1031 are all equidistant from the center of the ejector hole 104, so that the first wire hole 1011, the second wire hole 1021 and the third wire hole 1031 are also distributed in a circle around the ejector hole 104.

[0035] The first slide groove 101 has a matching slot 106 on each of its opposite sides; the two matching slots 106 correspond to the second slide groove 102 and the third slide groove 103 respectively, and the matching slots 106 are also triangular in structure.

[0036] like Figure 1 , 2 As shown in Figure 5, shearing blocks 2 are slidably connected in the first slide groove 101, the second slide groove 102, and the third slide groove 103. Specifically, the first slide groove 101, the second slide groove 102, and the third slide groove 103 can be configured as dovetail grooves, and the shearing blocks 2 cooperate with them to slide. One end of the shearing block 2 is connected to a second driving device 4, which can be a cylinder, a hydraulic cylinder, or a cam mechanism, etc., so that the shearing block 2 can reciprocate. A shearing hole is opened on the side of the shearing block 2, which is used to cut the wire.

[0037] The shearing block 2 has a triangular structure at one end that mates with the end of the first slide groove 101 and the alignment slot 106, allowing the shearing block 2 to be precisely aligned. An annular cutter 201 is fixedly connected to the inner wall of the shearing hole. The annular cutter 201 can be fixed with the shearing hole by interference fit. A threaded hole communicating with the shearing hole can also be opened on the side of the shearing block 2. The annular cutter 201 is squeezed and limited by screws. The annular cutter 201 can improve the convenience of wire cutting and also facilitate the replacement of the annular cutter 201 to ensure the cutting effect.

[0038] like Figure 2 and 3 As shown, the other side of the mounting plate 1 has a bottom mold hole that communicates with the ejector pin hole 104 and is concentrically arranged; a fixing plate 105 is fixedly connected to one side of the mounting plate 1 at the bottom mold hole via a connecting rod; a first driving device 3 is fixedly connected to the side of the fixing plate 105; the first driving device 3 is connected to an ejector pin 301 corresponding to the bottom mold hole; the first driving device 3 can be a cylinder, a hydraulic cylinder or a cam mechanism, so that the ejector pin 301 can reciprocate by being pushed into the bottom mold hole and being able to reset.

[0039] The side of the fixing plate 105 is provided with wire passage holes 107 corresponding to the first wire hole 1011, the second wire hole 1021 and the third wire hole 1031 respectively. The wire passage holes 107 are used to guide and support the wire.

[0040] The bracket is fixedly connected to the upper surface of the base plate by screws. A third drive device 5 is installed on the support. The third drive device 5 is the same as the second drive device 4 or the first drive device 3. The third drive device 5 is located on the side close to the ejector pin hole 104. The third drive device 5 is connected to the ejector pin 501 corresponding to the ejector pin hole 104.

[0041] Specifically, a sliding block with a groove is installed on the bracket, or the slider is connected to the guide rail. One side of the slider is connected to the third drive device 5, and the other side is equipped with a ejector pin 501, which can be inserted into the ejector pin hole 104.

[0042] When the three shearing blocks 2 are in the reset position, the annular cutters 201 on the three shearing blocks 2 correspond to the first wire hole 1011, the second wire hole 1021, and the third wire hole 1031, respectively. When the wire enters the annular cutter 201, the second driving device 4 pushes the shearing blocks 2 to cut the wire. The wire in the first wire hole 1011 and the third wire hole 1031 is silver, and the wire in the second wire hole 1021 is copper, thus ensuring that the two ends of the processed contact are silver and the middle is copper. After the three shearing blocks 2 cut the wire, the lower end of the shearing block 2 in the first slide groove 101 matches the triangular structure at the lower end of the first slide groove 101, and the shearing blocks 2 in the second slide groove 102 and the third slide groove 103 match the alignment slots 106, thus enabling the three shearing blocks 2 to complete the position positioning. At this time, the three annular cutters 201 all correspond to the ejector pin holes 104.

[0043] At this time, the third driving device 5 drives the ejector pin 501 to push the three wire segments through the ejector pin hole 104 into the bottom mold hole on the other side of the mounting plate 1. Then, the first driving device 3 drives the ejector pin 301 to punch the wire segments in the bottom mold hole, thereby realizing the contact forming. After the ejector pin 301 is reset, the formed contact is finally pushed out of the bottom mold hole by the ejector pin 501 to complete the material discharge.

[0044] After discharge, the ejector pin 501 is reset, and then the shearing blocks 2 in the first slide 101, the second slide 102 and the third slide 103 are reset to prepare for the next shearing.

[0045] By setting three shearing blocks 2, the shearing directions of the three line segments at the joint are different, which helps to improve the joint strength of the line segments and ensure the overall structural strength of the contact. The three shearing blocks 2 can perform shearing and resetting simultaneously, which improves the shearing speed and ensures production efficiency.

[0046] Meanwhile, the three shear blocks 2 are individually formed to be relatively short, and each of them is provided with an alignment slot 106 at its forward end for limiting, which effectively ensures the alignment accuracy of the line segment and the overall quality of the contact point.
