Fixture grooves 304 are provided on one side near the center of the rotating disk 2 and on the other side near the edge of the rotating disk 2. Two fixture sliders 302 are slidably disposed in the two fixture grooves 304 respectively. A fixture fixing block 308 is provided on the side of the fixture groove 304 away from the fixture cavity 303. An elastic element is provided between the fixture slider 302 and the fixture fixing block 308. The elastic element can drive the fixture slider 302 to move closer to the fixture cavity 303. The top of the fixture cavity 303... The fixture is provided with a base positioning groove 305, and a fixture slide rod 306 is provided on the top of the fixture slider 302. The end of the fixture slide rod 306 near the base positioning groove 305 is provided with an L-shaped hook limiting groove 307 with an upward opening. The hook limiting groove 307 can be moved above the base positioning groove 305. The fixture cavity 303 is connected to two fixture slide grooves 304. The opening device 9 can open the two fixture sliders 302 from below the fixture 3. The fixed base plate 1 is installed inside the machine housing 18.Function: 1. By setting a fixed base plate, a rotating disk that can rotate intermittently is provided in the middle of the fixed base plate. Several jigs are provided on the edge of the rotating disk, and the jigs are evenly distributed along the circumference of the rotating disk. The fixed base plate is provided with a base mounting device, a spring mounting device, a moving plate mounting device, a support rod mounting device, and a housing mounting device arranged in sequence around the circumference of the rotating disk. The fixed base plate is also provided with several spreading devices arranged in sequence around the circumference of the rotating disk. The base mounting device, spring mounting device, moving plate mounting device, support rod mounting device, and housing mounting device can be assembled from above the jigs. A micro switch; thus, when the rotating disc carries several fixtures to rotate intermittently, each fixture can stop in sequence below the base mounting device, spring mounting device, moving piece mounting device, support rod mounting device, and housing mounting device, so that each fixture can be assembled with the base mounting device, spring mounting device, moving piece mounting device, support rod mounting device, and housing mounting device in sequence to assemble the micro switch. The micro switch 20 on each fixture will be assembled from the micro switch base 21, micro switch spring 22, micro switch moving piece 23, micro switch support rod 24, and micro switch housing 25 from bottom to top. 2. The fixture comprises a fixture body and two fixture sliders. A fixture cavity is located in the middle of the fixture body. Fixture grooves are located on one side of the fixture body near the center of the rotating disk and another side near the edge of the rotating disk. The two fixture sliders are slidably mounted in the two fixture grooves. A fixture fixing block is located on the side of the fixture groove away from the fixture cavity. An elastic element is located between the fixture slider and the fixture fixing block, which can drive the fixture slider closer to the fixture cavity. A base positioning groove is located at the top of the fixture cavity. A fixture sliding rod is located at the top of the fixture slider. An L-shaped hook limiting groove with an upward opening is located at the end of the fixture sliding rod near the base positioning groove. The hook limiting groove can move above the base positioning groove. The fixture cavity is connected to the two fixture grooves. A spreading device can spread the two fixture sliders apart from below the fixture. A fixed base plate is installed... Inside the housing; thus, in the several assembly steps of assembling the micro switch base 21, micro switch spring 22, micro switch moving piece 23, micro switch support rod 24, and micro switch housing 25 from bottom to top, in certain necessary assembly steps (such as the assembly steps of the micro switch base, micro switch support rod, and micro switch housing), the spreading device can be used to enter the fixture cavity and fixture slide groove from below the fixture and spread the two fixture sliders. Then, the two fixture sliders, along with the two fixture slide rods, move away from each other, thereby eliminating the possible interference of the assembly steps caused by the fixture slide rods. After completing these corresponding assembly steps, the spreading device exits the fixture slide groove and fixture cavity in sequence, causing the elastic element to drive the fixture sliders to approach the fixture cavity along the fixture slide groove. Then, the two fixture sliders, along with the two fixture slide rods, move closer to each other again.The key lies in the fact that, since the two fixture slides are normally close to each other, during the assembly of the micro switch spring 22, the middle of the micro switch spring 22 will be positioned above the micro switch base 21, and the two hooks 19 of the micro switch spring 22 will be located in two hook limiting grooves and subject to limiting action, thus preventing the two hooks 19 from falling to one side. In this way, during the subsequent assembly steps of the micro switch moving piece 23 and the micro switch support rod 24, the two hooks 19 of the micro switch spring 22 can be easily hooked together with the micro switch moving piece 23 and the micro switch support rod 24, respectively. From the above analysis, it can be seen that the rotary switch assembly machine with hook limiting fixture of this utility model, by setting hook limiting grooves on the fixture slides, can effectively hook the two hooks of the micro switch spring together with the micro switch moving piece and the micro switch support rod, thereby realizing the automated assembly of the micro switch.

Function: The first suction component 408, through horizontal and vertical movement, adsorbs and fixes the micro switch base 21 and moves it from the base vibratory feeder automatic feeding mechanism 401 to above the base positioning groove 305. Then, the spreading device 9 spreads open the two fixture sliders 302 from below the fixture 3. Then, the first suction component 408 installs the micro switch base 21 from above the fixture 3 downward into the base positioning groove 305. Finally, the first suction component 408 and the spreading device 9 are reset, and the fixture flows to the next station. The first buffer can provide a buffering effect, preferably a spring.

[0022] Specifically, each of the two cylinder fingers 5024 has a clearance notch 5025, and each of the clearance notches 5025 has a semi-circular hole 5026 on both sides.
