[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] Referring to the accompanying drawings: This switch accessory and spring forming and assembly machine includes a base plate 1 and a rotating disc 2 arranged on the base plate 1. The rotating disc 2 has a plurality of placement components 3 for placing switch accessories. The placement components 3 have a preset shape that can be moved upward by being squeezed. The base plate 1 is provided with an extrusion component 4 for squeezing the placement components 3 upward at a position located on one side of the rotating disc 2, and a support block 5 arranged crosswise with the extrusion component 4. A workbench 51 is provided on the support block 5, and a fixed The workbench 51 is provided with a guide channel 51-1 for indicating the moving direction of the reed copper strip, a forming groove 51-2 perpendicular to the guide track of the guide channel 51-1 and located below the reed copper strip, and a through opening 51-3 for allowing the switch accessory to enter the forming groove 51-2 when the placement component 3 is squeezed and pushes the switch accessory upward. A moving component 6 for driving the reed copper strip to move, a flattening component 7 for flattening the reed and the switch accessory, and a riveting component 8 for cutting the reed from the reed copper strip and riveting it to the switch accessory are provided on the workbench 51. The principle of the present invention is that the placement components 3 are arranged on the rotating disc 2 and are evenly distributed along its circumferential direction, and then the switch accessories are placed on the placement components 3, and the rotating disc 2 rotates, each time it rotates an angle, and the angle value is the quotient of 360° / N (the number of placement components 3). When one of the placement components 3 is replaced to the bottom of the workbench 51 (that is, the placement component 3 matches the position of the through-hole 51-3), the extrusion component 4 drives the placement component 3 to move upward, that is, the placement component 3 moves upward through the through-hole 51-3 so that the switch accessories are located in the forming groove 51-2, and the reed copper strip enters the guide channel 51-1. The trajectory provided by the guide channel 51-1 makes the reed copper strip located at the through-hole 5 1-3, so that when the reed on the reed copper strip moves to above the through-port 51-3, the flattening component 7 is started, that is, the reed and the switch accessory are flattened, and the positioning before riveting is achieved. The movement of the reed copper strip is achieved by the moving component 6. The moving component 6 makes the distance that the reed copper strip moves each time the interval distance between the two reeds, that is, each time the movement is triggered, the adjacent reeds can be located at the position corresponding to the switch accessory. The riveting component 8 realizes the riveting of the reed and the switch accessory, and cuts it at the same time to separate it from the reed copper strip. This method can not only realize streamlined operation, but also ensure the riveting quality of the reed and the switch accessory, and can avoid the occurrence of misaligned riveting.

[0023] The placement component 3 includes an outer sleeve 31, a moving rod 32 in the inner cavity of the outer sleeve 31, and a switch accessory placement block 33 inserted at the upper end of the moving rod 32. The outer sleeve 31 is inserted on the rotating disc 2 and fixed by bolts. The lower end of the moving rod 32 extends outside the outer sleeve 31 and has a triangular extruded end, which is used in conjunction with the extrusion component 4. The switch accessory placement block 33 has a slot 33-1 that is plugged into the switch accessory. Such an arrangement enables the placement component 3 to be fixed on the rotating disc 2, so that the extrusion component 4 can be driven to place the switch accessory. When the placement component 3 moves upward, only the moving rod 32 moves, and the outer sleeve 31 remains stationary. The switch accessory placement block 33 is used to place the switch accessories, and a slot 33-1 is provided so that the switch accessories can be inserted into the switch accessory placement block 33, making placement convenient and also providing lower support for the switch accessories. The triangular configuration of the squeezed end of the moving rod 32 can reduce the volume of the squeezed end, so that the contact point between the squeezed end and the squeezing component 4 after contact is located at the position closest to the placement component 3, avoiding the situation where the moving rod 32 cannot move into place.

[0024] The outer sleeve 31 is provided with a limit groove 31-1 perpendicular to the extension direction of its inner cavity. A limit rod 31-2 is provided in the limit groove 31-1. The movable rod 32 is provided with a movable channel 32-1 matching the direction of the limit groove 31-1. The limit rod 31-2 is placed in the movable channel 32-1 to keep the movable rod 32 in the inner cavity of the outer sleeve 31 when the movable rod 32 moves and contacts the upper end of the movable channel 32-1, and to limit the maximum movement distance of the movable rod 32 when it contacts the lower end. Such an arrangement allows the switch accessory placed on the switch accessory placement block 33 to enter the forming groove 51-2 after the moving rod 32 moves the maximum distance, and the switch accessory is not exposed outside the forming groove 51-2, so that it is in place at one time. At the same time, it also allows the moving rod 32 to always remain in the outer sleeve 31, preventing the moving rod 32 from separating from the outer sleeve 31, and the limiting rod 31-2 is tightly matched with the limiting groove 31-1, so that the limiting rod 31-2 is stably maintained in the limiting groove 31-1 and the moving channel 32-1.

[0025] The support block 5 is provided with an installation space 52 extending along its width direction and passing through the support block 5. The extrusion assembly 4 is placed in the installation space 52, which includes an extrusion block 41 with an extrusion slope 41-1, and a first cylinder 42. The extrusion block 41 is moved by a slide block provided on the base plate 1. The first cylinder 42 is provided on the base plate 1 and its piston rod is provided on the extrusion block 41. The extruded end of the moving rod 32 is provided with a rotatable roller 32-2 for contacting the extrusion slope 41-1. The roller 32-2 moves along the track provided by the extrusion slope 41-1 to cause the moving rod 32 to be extruded and moved. Such an arrangement enables the extrusion assembly 4 to be located directly below the through-port 51-3, so that the extrusion assembly 4 can be moved when extruding. During the pressing movement, it can quickly contact the placement component 3 which is also in this position. The extrusion is achieved by the extrusion block 41. The extrusion block 41 has an extrusion slope 41-1. The inclination of the extrusion slope 41-1 is downward from the cylinder end to the placement component 3 end. As the extrusion block 41 moves toward the placement component 3 under the drive of the first cylinder 42, the height of the extrusion slope 41-1 increases with the increase of the moving distance, thereby driving the moving rod 32 to move upward, and the roller 32-2 achieves tangential contact with the extrusion slope 41-1 and increases the contact area. It can rotate by friction with the extrusion slope 41-1, which can avoid wear on the extrusion slope 41-1, extend its service life, and reduce the maintenance frequency.

[0026] The moving assembly 6 includes a mounting seat 61, a first moving block 62, a second cylinder 63, an extension block 64, a third cylinder 65, a second moving block 66, and a push head 67. The mounting seat 61 is arranged on the workbench 51 and is parallel to the moving direction of the reed copper strip. The first moving block 62 is moved by a slide rail slider arranged on the mounting seat 61. The second cylinder 63 is arranged on the mounting seat 61 and its piston rod is arranged on the first moving block 62. The extension block 64 is arranged on the first moving block 62 and is perpendicular to the moving direction of the first moving block 62. The third cylinder 65 is arranged on the outer side of the extension block 64. The second moving block 66 has an L-shaped configuration. Its transverse section is arranged on the piston rod of the third cylinder 65, and the vertical section moves on the slide rail arranged on the side of the third cylinder 65. The push head 67 is arranged on the transverse section of the second moving block 66 and is perpendicular to the extension direction of the extension block 64. Such an arrangement enables the moving assembly 6 to have two power sources, one power source is used to adjust The lateral position of the push head 67 (i.e. the second cylinder 63) and another power source are used to adjust the vertical position of the push head 67 (i.e. the third cylinder 65). When the second cylinder 63 is started, on the one hand, it is used to drive the first moving block 62 to move in the direction close to the flattening component 7, and on the other hand, it drives the first moving block 62 to move in the direction away from the flattening component 7, which is a pushing and resetting action. When the third cylinder 65 is started, on the one hand, it is used to drive the second moving block 66 to move in the direction close to the reed copper strip, and on the other hand, it drives the second moving block 66 to move in the direction away from the reed copper strip, which is an insertion and resetting action. In this way, when the push head 67 is inserted into the reed channel (i.e., leaning on the left side of the reed), the second cylinder 62 pushes the reed adjacent to the forming groove 51-2 to move above the forming groove 51-2 (i.e., directly above the through-port 51-3). After reaching the position, the second cylinder 62 and the third cylinder 65 are both reset, thereby realizing the equidistant movement of the reed copper strip.

[0027] The flattening assembly 7 includes a support plate 71, a mounting plate 72, a fourth cylinder 73, and a connecting block 74. The support plate 71 is arranged on the workbench 51, the mounting plate 72 is arranged on the support plate 71 and is perpendicular to the extension direction of the support plate 71, the fourth cylinder 73 is arranged on the mounting plate 72 and is located directly above the through port 51-3, the connecting block 74 is arranged on the piston rod of the fourth cylinder 73, and the riveting assembly 8 is arranged on the connecting block 74 to flatten both the reed and the switch accessory by driving the riveting assembly 8. The fourth cylinder 73 is arranged to be located at a high position, that is, the support plate 71 provides the height, the mounting plate 72 provides the mounting area to realize the connection with the fourth cylinder 73, and the connecting block 74 is connected to the fourth cylinder 73 and the riveting assembly 8 at the same time, so that under the action of the fourth cylinder 73, the riveting assembly 8 can be controlled to move up and down, and the riveting assembly 8 can be used to flatten both the reed and the switch accessories. The purpose of flattening is to achieve that the two can be positioned before riveting, so as to ensure the subsequent riveting quality.

[0028] The riveting assembly 8 includes a fifth cylinder 81, a mounting block 82, and a riveting head 83. The fifth cylinder 81 is arranged on the connecting block 74, the mounting block 82 is arranged on the piston rod of the fifth cylinder 81, and the riveting head 83 is arranged on the mounting block 82. Such an arrangement allows riveting to be powered by the fifth cylinder 81. The cylinder can provide sufficient kinetic energy and a clear movement guide. The mounting block 82 is used to communicate with the riveting head 83.

[0029] A fixed block 9 is provided on the work table 51, and a guide block 91 is provided in the fixed block 9 to provide guidance for the riveting head 83 when it moves. Such a setting is used to provide constraint guidance for the riveting head 83, that is, two side surfaces of the riveting head 83 are fitted with two side surfaces of the guide space, so that the riveting head 83 can remain stable regardless of its movement during flattening or riveting, and can also increase the structural strength of the head section of the riveting head 83.

[0030] Two blocks 92 with a distance between them are provided on the fixed block 9. The fifth cylinder 81 is placed in the distance formed by the two blocks 92, and the inner side surface of the block 92 fits with the outer side surface of the fifth cylinder 81. Such a setting can increase the stability of the fifth cylinder 81 during movement, that is, no shaking occurs, thereby achieving a good flattening effect, and the connecting block 74 can also contact the block 92, that is, the contact limits the moving distance of the fourth cylinder 73 driving the riveting assembly 8.
