Specifically, the rotary switch is twisted by rotating the structure to detect the output point of the rotary switch or the corresponding state of the PCBA to determine the quality of the encoder and PCBA products.

[0003] However, different models of rotary switches have different shapes for the parts that need to be turned. This means that in actual operation, a matching sleeve must be provided for each model of rotary switch, resulting in a large number of sleeves required for the entire rotating mechanism, increasing costs. Furthermore, during testing, the coded switch must be adjusted to the same direction as the sleeve before pressing down, adding to the testing steps. Utility Model Content

[0024] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0025] like Figure 1-6 As shown, the rotary switch test universal rotary mechanism includes motor 1; it also includes: Connecting sleeve 3, which is connected to the output shaft of motor 1, and a square post 303 is provided at the bottom end of the connecting sleeve 3, and positioning grooves 304 are provided on both sides of the square post 303. Sleeve 4, the top of sleeve 4 is provided with a square hole 401 suitable for square column 303, and two positioning mechanisms 6 for inserting into positioning groove 304 are symmetrically arranged on both sides of square hole 401. The two positioning mechanisms 6 are connected to movable ring 5, and the movable ring 5 is slidably sleeved to the outside of sleeve 4. The bottom end of the sleeve 4 is provided with a bottom groove 405, and a number of telescopic rods 7 are filled in the bottom groove 405.

[0026] In practical implementation, the entire rotating mechanism moves downwards, pressing directly onto the rotary switch via the telescopic rod 7 on the sleeve 4. The bottom end of the telescopic rod 7 directly contacts the position where the rotary switch needs to be rotated. The telescopic rod 7 is retractable; it contracts under pressure. Figure 5 As shown, when the telescopic rods 7 are not under pressure, their bottom ends form a plane. Under the aforementioned pressure conditions, they are recessed into the shape of the position where the rotary switch needs to be rotated, thus enabling automatic adaptation to different models of rotary switches. Then, the motor 1 drives the connecting sleeve 3 and the sleeve 4 to rotate, and the sleeve 4 drives the rotary switch to rotate.

[0027] The above design enables the rotary mechanism to be compatible with different types of rotary switches.

[0028] like Figure 1-2 As shown, it also includes a mounting bracket 2; the motor 1 is fixedly mounted on the mounting bracket 2, and multiple mounting slots 201 are provided on both sides of the mounting bracket 2.

[0029] Mounting bracket 2 is used for installation on external equipment, specifically on a lifting mechanism. The lifting mechanism is used to drive the entire rotating mechanism to move up and down. When testing the rotary switch, the rotating mechanism is moved downward to press down the rotary switch; after the test, the rotating mechanism is moved upward to separate from the rotary switch.

[0030] like Figure 1-2 As shown, the connecting sleeve 3 has an insertion hole 301 at its shaft center, which is inserted into the output shaft of the motor 1. The connecting sleeve 3 has multiple evenly distributed mounting holes 302 on its circumference, and screws are threaded into the mounting holes 302 and pressed into the output shaft of the motor 1.

[0031] The connecting sleeve 3 is fixed to the output shaft of the motor 1 by screws, and the connecting sleeve 3 provides a mounting position for the sleeve 4.

[0032] like Figure 3As shown, the positioning mechanism 6 includes a positioning socket 602 and a pressing seat 601. A first sliding groove 402 is provided on the side wall of the square hole 401. The positioning socket 602 is slidably connected to the first sliding groove 402. A second sliding groove 403 and a third sliding groove 404 are provided at the bottom of the first sliding groove 402. A protrusion is provided at the bottom of the positioning socket 602, and the protrusion is slidably installed in the second sliding groove 403. The protrusion is elastically connected to the end face of the second sliding groove 403 via a first spring 604. A slider 605 is fixedly installed at the bottom of the pressing seat 601. The slider 605 is slidably sleeved with the third sliding groove 404, and multiple second springs 606 are provided in the third sliding groove 404. The slider 605 is elastically connected to the bottom surface of the third sliding groove 404 via the second springs 606. One end of the pressing seat 601 is fixedly connected to the inner ring of the movable ring 5. A recessed hole 603 is provided on the protrusion, and the first spring 604 is disposed in the recessed hole 603. The compression seat 601 and the positioning socket 602 are respectively provided with a first inclined surface and a second inclined surface, and the first inclined surface and the second inclined surface abut against each other.

[0033] Sleeve 4 is installed on connecting sleeve 3 via positioning mechanism 6; when sleeve 4 is installed, the initial state of positioning mechanism 6 is as follows: Figure 3-4 As shown, the operator holds the sleeve 4 with one hand and pulls the movable ring 5 upward with the other. The movable ring 5 drives the extrusion seat 601 to move upward until the extrusion seat 601 is in contact with the top surface of the first slide groove 402. During the above process, the extrusion seat 601 drives the slider 605 to slide upward in the third slide groove 404 and stretches the second spring 606. At the same time, the positioning socket 602 is compressed by the first spring 604, so that the second inclined surface of the positioning socket 602 is always in contact with the first inclined surface of the extrusion seat 601. Specifically, the positioning socket 602 moves into the first slide groove 402 and through the square hole 4. 01. Remain in the above state, allowing the square hole 401 of the sleeve 4 to be inserted into the square post 303. After insertion, the end of the positioning socket 602 is aligned with the positioning groove 304 on the square post 303. Then, release the movable ring 5. Through the tension of multiple second springs 606, the slider 605, the pressing seat 601, and the movable ring 5 move downwards to reset. The pressing seat 601, through the first inclined surface, presses and pushes the second inclined surface of the positioning socket 602, causing the positioning socket 602 to be inserted into the positioning groove 304 and compressing the first spring 604. The positioning mechanism 6 returns to its original position. Figure 3-4 As shown in the diagram, the installation of sleeve 4 is complete.

[0034] It should be noted that, in cases such as Figure 3-4 In the indicated state, the first spring 604 is in a compressed state, the second spring 606 is in a stretched state, and the number of second springs 606 is greater than the number of first springs 604. The tensile force of the multiple second springs 606 is sufficient to keep the positioning mechanism 6 in the position shown. Figure 3-4 The state shown.

[0035] When disassembling the sleeve 4, hold the sleeve 4 with one hand and pull the movable ring 5 upward with the other hand to move the positioning socket 602 into the first sliding groove 402 and separate it from the positioning groove 304. Then move the sleeve 4 to separate the square post 303 from the square hole 401 to complete the disassembly.

[0036] The above design facilitates the disassembly and installation of the sleeve 4 on the connecting sleeve 3, enabling disassembly and maintenance. If dirt or dust enters the bottom groove 405 of the sleeve 4, it can be removed for cleaning.

[0037] The assembly and disassembly of the sleeve 4 can be achieved simply by pulling down the movable ring 5 and moving the sleeve 4, making the overall operation simple and convenient.

[0038] like Figure 2 The outer wall of the movable ring 5 shown has several anti-slip ridges arranged in a circular array. The anti-slip ridges serve to prevent slipping.

[0039] like Figure 6 As shown, the telescopic rod 7 includes a movable sleeve 701 and a fixed post 702; the top end of the fixed post 702 is fixed to the top groove surface of the bottom groove 405, and the movable sleeve 701 is slidably sleeved onto the fixed post 702. An end seat 703 is fixedly installed at the bottom end of the fixed post 702, and the end seat 703 fits into the movable sleeve 701. An end hole 704 is provided at the top end of the movable sleeve 701, and the end hole 704 is slidably sleeved onto the fixed post 702.

[0040] Figure 6 In the middle, the telescopic rod 7 is in its natural state and is not under pressure; when the bottom end of the telescopic rod 7 is under pressure, the movable sleeve 701 slides upward about the fixed post 702 and retracts; when the pressure is released, the movable sleeve 701 moves downward by gravity and returns to its original position. Figure 6 The state shown.
