It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art.

[0019] The moving contact assembly device of this utility model includes a base plate 1, a cylinder 5, and a slide plate 6. A vertical plate 3 is arranged on one side of the rear end of the base plate 1 via a vertical arm 2. The cylinder 5 is vertically arranged on the front side of the vertical plate 3, and the drive plate of the cylinder 5 is located below it. A fixing plate 4 is provided on the drive plate, and a first stamping assembly is detachably mounted on the fixing plate 4. The slide plate 6 is movably mounted on the top of the base plate 1. A first support platform 8 is provided on the rear side of the top of the slide plate 6. Two positioning seats 10 are symmetrically arranged on the rear side of the top of the first support platform 8. The top of the positioning seats 10 is provided with positioning blind holes 11. The positioning seats and positioning blind holes are used for rapid positioning of the moving contact. The front end of the top of the first support platform 8 is also provided. A first positioning through groove 12 is provided through its left and right sides. The first positioning through groove is an L-shaped through groove and also extends through the front and top sides of the first support platform. A second support platform 9 is provided on the top front side of the slide plate 6. A second positioning through groove 13 is provided at the top left and right ends of the second support platform 9. The second positioning through groove 13 extends through the rear, left or right side of the second support platform 8. A clearance through groove 14 is provided on the second support platform 9 located inside the second positioning through groove 13. The clearance through groove 14 is arranged parallel to the second positioning through groove 13 and is interconnected with it. Its bottom surface is lower than the bottom surface of the second positioning through groove. A number of convex positioning rods 15 are arranged between the first support platform 8 and the second support platform 9.

[0020] To facilitate the description of this assembled equipment, the front-back and left-right directions are defined according to the arrangement of the support assembly, moving contact assembly, and pressure switch body on this device assembly, and its structure is described in a simple manner. The support assembly is composed of a balance bracket and a diaphragm bracket. The balance bracket is a concave frame with an opening on the front. Two long frames are symmetrically arranged on the rear side of the top of the balance bracket. The diaphragm bracket is located inside the balance bracket and is rotatably connected to the side plate at the opening of the balance bracket via two support arms. The moving contact assembly consists of a horizontal fixed end, a bent part, and a free end connected in sequence. The horizontal fixed end is threaded with a wiring screw. The pressure switch body has an irregular structure. Its rear part can be slightly interference-fitted with the balance bracket. There are two through holes on each of the left and right sides of its front part, which are adapted to the convex positioning rod to achieve quick positioning. There are two sets of through holes on the top and rear ends. The rear side has two through holes for mounting moving contact components, and the front side has two through holes for mounting fixed contact components. There are two rectangular through slots between the two mounting through holes, and L-shaped through slots on the left and right outer sides. There are elastic upright plates on the side of the rectangular through slots and L-shaped through slots away from the mounting through holes. The fixed contact components are installed in the pressure switch body before the moving contact components.

[0021] In use, first place the bracket assembly on the movable seat. The rear end of the balance bracket is located in the first positioning slot of the first support platform, and the two side plates at its front opening are respectively located in the two positioning slots of the second support platform. At this time, the two arms of the diaphragm bracket are located in the clearance slot, and its body is naturally tilted on the slide plate on the rear side of the second support platform. Then, the free end of the front side of the moving contact assembly is inserted into the long frame of the balance bracket with the front end protruding, and the horizontal fixed end of the rear side is placed on the positioning seat with its circumference protruding outside the positioning seat. The lower end of the wiring screw is inserted into the positioning blind hole to achieve relative fixation. After the two are arranged together, the two through holes of the pressure switch body are fitted onto the convex positioning rod, and the pressure switch body is located on the top of the bracket assembly. Then, the cylinder controls the first stamping assembly to move downward and press the top rear side of the pressure switch body to install the moving contact assembly. The balance bracket also enters the pressure switch.

[0022] Specifically, the first stamping assembly includes a stamping block 16 and stamping rods 17. The stamping block 16 is detachably mounted on the bottom of the fixed plate. There are two stamping rods 17, vertically and symmetrically arranged on the bottom of the stamping block 16. The two stamping rods correspond to the two moving contact assembly mounting through holes on the pressure switch body. The cylinder controls the first stamping assembly to move downward, and the two stamping rods press against the two moving contact assembly mounting through holes, causing the entire pressure switch body to move downward. The horizontal fixed end of the moving contact assembly is inserted into the pressure switch body, and its wiring screw is located in the mounting through hole. The left and right ends of its horizontal fixed end are in the L-shaped through groove and the rectangular through groove, and its bottom is slightly in contact with the top of the elastic upright plate. The bracket assembly is inserted into the pressure switch body. The moving contact assembly and the bracket assembly are locked in the pressure switch body and will not come out.

[0023] To ensure the stability of the moving contact assembly, the elastic vertical plates within the rectangular and L-shaped through slots on both sides of the mounting hole of the moving contact assembly are retracted inwards, pressing them tightly against the horizontal fixed end of the moving contact assembly. Therefore, a second stamping assembly is also included. After assembly, the second stamping assembly is replaced to achieve the retraction of the moving contact assembly after installation. Different functions can be achieved by replacing the stamping assemblies. However, in actual production, two assembly machines are used, with the first and second stamping assemblies respectively arranged to achieve their functions.

[0024] Specifically, the second stamping assembly includes a stamping block 16 and a settling assembly 18. The stamping block 16 is detachably disposed at the bottom of the fixed plate. The settling assembly 18 includes two clamping rods 181, two first clamping plates 182, and two second clamping plates 183. The two clamping rods 181 are vertically and symmetrically disposed at the bottom of the stamping block 16. The two first clamping plates 182 are symmetrically arranged on the outside of the two clamping rods 181, and the two second clamping plates 183 are symmetrically arranged on the inside of the two clamping rods 181. The opposite sides of the first clamping plates 182 and the second clamping plates 183 form a guide edge and a vertical clamping edge from bottom to top.

[0025] Two clamping rods correspond to the two through holes for mounting the moving contact components on the pressure switch body, respectively. Two first clamping plates correspond to the L-shaped through slots on both sides of the through holes for mounting the moving contact components, and two second clamping plates correspond to the two rectangular through slots inside the through holes for mounting the moving contact components. The cylinder controls the second stamping component to move downwards, and the two clamping rods press against the two through holes for mounting the moving contact components to keep them stationary. The first and second clamping plates are simultaneously inserted into the corresponding through slots, pressing the elastic vertical plate inwards, causing its top to tighten inwards to the bottom of the left and right sides of the horizontal fixed end, thus fixing the moving contact component in place. In other words, by increasing the contact area between the horizontal fixed end of the moving contact component and the top of the elastic vertical plate, the moving contact component is stabilized and immobilized.

[0026] In this embodiment, the sliding plate is positioned on top of the base plate. After arranging the bracket assembly, moving contact assembly, and pressure switch body, it is pushed under the cylinder. At this point, the person's hand is at the foremost position of the pressure switch body, eliminating the risk of injury from potential cylinder failure.

[0027] Specifically, a base 19 is provided on the top of the base plate 1 along its front-back direction. The front and rear sides of the base 19 have limiting plates 20. Two guide rods 21 are provided between the two limiting plates 20. The slide plate 6 is movably sleeved on the two guide rods 21 and can move back and forth along the guide rods.

[0028] Meanwhile, a limiting bolt 22 is threaded onto the rear limiting plate 20 of the base, and the limiting bolt 22 extends forward from the limiting plate 20. The extension length of the limiting bolt is used to position the slide plate to move backward, aligning it with the stamping assembly.

[0029] In addition, a foot switch 23 is included. A solenoid valve 24 is provided on one side of the upright arm 2. The solenoid valve 24 is connected to an external air source and a cylinder via air pipes. The solenoid valve 24 is electrically connected to the foot switch 23. The foot switch controls the opening and closing of the air circuit, thereby controlling whether the cylinder operates.

[0030] In addition, to further ensure personnel safety and prevent accidental hand injuries during stamping component replacement, an infrared photoelectric sensor 7 is installed on one side of the vertical arm 2 via a bracket. When the external photoelectric sensor detects a hand or arm in front of the cylinder, pressing the foot switch will not activate the cylinder.
