Detailed Implementation

[0048] This utility model discloses a signal testing support structure for a photoelectric detection mechanism, which has better versatility, higher testing efficiency, and more complete testing functions.

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] See Figures 1 to 4 The photoelectric detection mechanism signal testing support structure of this utility model includes a support base 5, a first support frame 1, a second support frame 2, and a laser simulator 16. The first support frame 1 is detachably connected to one end of the support base 5 and has a first placement cavity for placing the photoelectric detection mechanism 17. The second support frame 2 is detachably connected to the other end of the support base 5 and has a second placement cavity for placing the photoelectric detection mechanism 17. The photoelectric detection mechanism 17 is placed in the first and second placement cavities, thereby achieving support for the photoelectric detection mechanism 17 by the first and second support frames 1 and 2. The laser simulator 16 is slidably connected to a slide rail on a rotating bracket 4. One end of the rotating bracket 4 is rotatably connected to the support base 5, and the other end is suspended outside the support base 5. The slide rail is parallel to the axial direction of the photoelectric detection mechanism 17 for easy detection. The laser simulator 16 can be placed near or away from the photoelectric detection mechanism 17.

[0051] The first and second placement cavities are coaxially arranged, and the photoelectric detection mechanism 17 is rotatably placed within the first and second placement cavities. The laser simulator 16 is used to emit lasers.

[0052] This utility model discloses a signal testing support structure for a photoelectric detection mechanism. By setting a first support frame 1 and a second support frame 2 to support the photoelectric detection mechanism 17, the structure achieves fixation and support for the mechanism. By rotatably placing the photoelectric detection mechanism 17 within the first and second placement cavities, allowing it to rotate around its axis, signals from different rotational axes can be detected. By mounting a laser simulator 16 on a rotating bracket 4, and slidably mounting the laser simulator 16 on the rotating bracket 4, dynamic target motion simulation can be provided, resulting in more comprehensive testing functions. This eliminates the need to install the photoelectric detection mechanism 17 on different testing devices for different tests, saving installation and disassembly time and increasing testing efficiency. The first support frame 1 and the second support frame 2 are detachably connected to the support base 5. Different models of photoelectric detection mechanisms 17 correspond to different models of the first support frame 1 and the second support frame 2. By replacing different models of the first support frame 1 and the second support frame 2, different photoelectric detection mechanisms 17 can be supported, thus making the testing support structure of this utility model more versatile.

[0053] Specifically, such as Figure 5 As shown, the first support frame 1 includes a first bottom support 102 and a first top support 101. The first bottom support 102 is detachably connected to the support base 5, and a first bottom support wheel is rotatably connected to the first bottom support 102. The first bottom support wheel is fixedly positioned near the first placement cavity and is used to support the photoelectric detection mechanism 17. To improve the stability of the support, at least two first bottom support wheels are provided. A first top support wheel is rotatably connected to the first top support 101 and is used to press the photoelectric detection mechanism 17. To reduce production difficulty, the first top support wheel is an elastic support wheel, that is, the first top support wheel is connected to the first top support 101 near the first placement cavity by a spring. At least one first top support wheel is provided. The first bottom support 102 and the first top support 101 form the first placement cavity. The first bottom support 102 is connected to the support base 5 by connecting bolts, thereby facilitating the replacement of different models of the first support frame 1 to support corresponding models of photoelectric detection mechanisms 17.

[0054] To facilitate the placement of the photoelectric detection mechanism 17, one end of the first top bracket 101 is rotatably connected to one side of the first bottom bracket 102 via a pivot, and the other end is connected to the first bottom bracket 102 via a connector. To place the photoelectric detection mechanism 17, the connector is opened, and the first top bracket 101 is opened around the pivot to place the photoelectric detection mechanism 17. To facilitate opening or closing the first top bracket 101, a first lifting handle 24 is provided at the end of the first top bracket 101 where the connector is located.

[0055] To facilitate the rotation of the photoelectric detection mechanism 17 around its axis, the signal testing support structure of the photoelectric detection mechanism of this invention also includes a rotating disk 15. A first mechanism fixing ring 19 is fixedly connected to the photoelectric detection mechanism 17 at the position of the first placement cavity. A stop 20 is provided on the outer surface of the first mechanism fixing ring 19 at the position of the first placement cavity. A slot is provided on the rotating disk 15 at a position corresponding to the stop 20, and the stop 20 is placed in the slot. The stop 20 and the slot, which are configured to cooperate, facilitate the positioning of the rotating disk 15.

[0056] To reduce the friction between the rotating disk 15 and the first support frame 1 during rotation, a guide ring 23 is provided on the end face of the first support frame 1 near the rotating disk 15. The guide ring 23 is arranged around the first placement cavity. The surface of the guide ring 23 that contacts the rotating disk 15 is coated with a coating that reduces friction, such as a carbon coating, to reduce the friction when the rotating disk 15 rotates. The guide ring 23 is used to support the rotating disk 15.

[0057] To facilitate the limiting of the photoelectric detection mechanism 17, which is rotatably connected to the first support frame 1 and the second support frame 2, a first limiting hole 30 is provided on the end face of the first support frame 1 near the rotating disk 15, and a second limiting hole is provided on the rotating disk 15. The second limiting hole is a through hole. The distance between the first limiting hole 30 and the axis of the photoelectric detection mechanism 17 is a first distance, and the distance between the second limiting hole and the axis of the photoelectric detection mechanism 17 is a second distance. The first distance and the second distance are the same, so that the radial positions of the first limiting hole 30 and the second limiting hole correspond, facilitating the insertion of the tail end of the pin 13, which is inserted into the second limiting hole, into the first limiting hole 30 when the rotating disk 15 rotates to a suitable angle. In one embodiment, the diameter of the first limiting hole 30 is the same as the diameter of the second limiting hole.

[0058] To accommodate the photoelectric detection mechanism 17 rotating to multiple different angles, multiple first limiting holes 30 are provided. These multiple first limiting holes 30 are positioned at different locations on the first support frame 1, and the intervals between the different first limiting holes 30 are set by those skilled in the art according to actual needs. It is understood that the centers of the different first limiting holes 30 are located on the same annulus. Only one second limiting hole is required to meet the requirements.

[0059] To facilitate observation of the rotation angle of the photoelectric detection mechanism 17, a first scale line is provided on the side of the first support frame 1, and a second scale line 14 is provided on the side of the rotating disk 15. The second scale line 14 serves as the alignment line for the rotating disk 15. The first scale line includes a zero scale line 21 and a set angle scale line 22. When the photoelectric detection mechanism 17 is initially positioned on the first support frame 1 and the second support frame 2, the second scale line 14 on the rotating disk 15 is aligned with the zero scale line 21. When a set angle needs to be rotated, the photoelectric detection mechanism 17 is rotated so that the second scale line 14 on the rotating disk 15 corresponds to the corresponding set angle scale line 22 on the first support frame 1. The set angle scale line 22 is set according to actual needs. Figure 5 As shown, the position of the angle scale line 22 is set at a 45° angle. In other embodiments, the angle scale line 22 can also be set to other angle positions required by those skilled in the art.

[0060] To facilitate the rotation of the rotating disk 15 mounted on the first mechanism fixing ring 19, a control handle 18 is provided on the rotating disk 15.

[0061] Furthermore, to facilitate the installation of the photoelectric detection mechanism 17, the second support frame 2 includes a second bottom support 202 and a second top support 201. The second bottom support 202 is detachably connected to the support base 5, such as... Figure 6 As shown, a second bottom support wheel 25 is rotatably connected to the second bottom bracket 202, and the second bottom support wheel 25 is used to support the photoelectric detection mechanism 17. It is understood that the second bottom support wheel 25 is fixedly positioned near the second placement cavity. To improve the stability of the support, at least two second bottom support wheels 25 are provided. A second top support wheel 31 is rotatably connected to the second top bracket 201, and the second top support wheel 31 is used to press the photoelectric detection mechanism 17. To reduce production difficulty, the second top support wheel 31 is an elastic support wheel, that is, the second top support wheel 31 is connected to the second top bracket 201 near the second placement cavity by a spring. At least one second top support wheel 31 is provided. The second top bracket 201 and the second bottom bracket 202 form the second placement cavity. The second bottom bracket 202 is connected to the support base 5 by connecting bolts, thereby facilitating the replacement of different models of the second support frame 2 to support the corresponding model of the photoelectric detection mechanism 17. Specifically, the arrangement structure of the first top support wheel is the same as that of the second top support wheel 31, and the arrangement structure of the first bottom support wheel is the same as that of the second bottom support wheel 25.

[0062] To avoid the supporting structure affecting the surface quality of the photoelectric detection mechanism 17, a second mechanism fixing ring 26 is fixedly connected to the photoelectric detection mechanism 17 at the position of the second placement cavity. The second top support wheel 31 and the second bottom support wheel 25 are pressed against the outer surface of the second mechanism fixing ring 26. In one embodiment, three second bottom support wheels 25 are provided, such as... Figure 6 As shown, there is one second top support wheel 31, and correspondingly, there are three first bottom support wheels and one first top support wheel. The specific arrangement structure is the same as that of the support wheels on the second support frame 2.

[0063] To facilitate the placement of the photoelectric detection mechanism 17, one end of the second top bracket 201 is rotatably connected to one side of the second bottom bracket 202 via a pivot, and the other end is connected to the second bottom bracket 202 via a connector. To place the photoelectric detection mechanism 17, the connector is opened, and the second top bracket 201 is opened around the pivot to place the photoelectric detection mechanism 17. To facilitate opening or closing the second top bracket 201, a second lifting handle 27 is provided at the end of the second top bracket 201 where the connector is located. To improve connection efficiency, the connector here can be a disc bolt that snaps into the notch.

[0064] To facilitate the installation of the rotating disk 15, the rotating disk 15 includes a first sub-shell 1501 and a second sub-shell 1502 connected together, and the first sub-shell 1501 and the second sub-shell 1502 are connected together by a connector. Both the first sub-shell 1501 and the second sub-shell 1502 are semi-circular shells, and the first sub-shell 1501 and the second sub-shell 1502 enclose a third placement cavity to facilitate the passage of the photoelectric detection mechanism 17, such as... Figure 5 As shown. The first sub-shell 1501 and the second sub-shell 1502 are mounted on the first mechanism fixing ring 19.

[0065] To facilitate control of the rotation of the rotating bracket 4, a geared motor 3 for driving the rotation of the rotating bracket 4 is provided on the support base 5. The geared motor 3 is connected to the support base 5 by connecting bolts, which are connected to the mounting holes 29. Figure 7 As shown. The motor shaft 28 of the geared motor 3 is connected to the connecting plate frame 6 by a key, and the connecting plate frame 6 is connected to the rotating bracket 4 by bolts and nuts. The slide rail is provided on the top surface of the rotating bracket 4. In order to protect the geared motor 3, a shielding net 8 is provided on the outside of the geared motor 3. The shielding net 8 surrounds the outside of the geared motor 3.

[0066] To limit the rotation of the rotating bracket 4, the support base 5 is equipped with a proximity switch 11 and a limit block 10 to limit the rotation angle of the rotating bracket 4, such as... Figure 7As shown, the proximity switch 11 is closer to the rotating bracket 4 than the limit block 10. Here, "closer" means that the rotation angle range limited by the proximity switch 11 is smaller, while the rotation angle range limited by the limit block 10 is larger. The limit block 10 provides mechanical limiting, while the proximity switch 11 provides electrical limiting. If a fault occurs during the rotation of the rotating bracket 4, it will first collide with the proximity switch 11 for electrical limiting, and only then with the limit block 10 for mechanical limiting, thus facilitating the protection mechanism. Specifically, the proximity switch 11 is installed within an angle range of ±50°, while the limit block 10 is installed within an angle range greater than the electrical limiting angle range.

[0067] To facilitate the movement of the signal testing support structure of this utility model to different locations, multiple casters 7 are installed on the bottom surface of the support base 5. For example... Figure 1 As shown, four casters 7 are provided, positioned at the edge of the support base 5. In other embodiments, lifting rings can be provided on the top surface of the support base 5, allowing the entire structure to be moved by a crane. To facilitate adjustment of the level of the support base 5, multiple height-adjustable support legs 9 are provided on the bottom surface of the support base 5.

[0068] In one embodiment, the support leg 9 includes a first connecting nut 901, a connecting screw 902, a second connecting nut 903, and a support base 904, as shown below. Figure 8 As shown. One end of the first connecting nut 901 is fixedly connected to the support base 5, and the other end is threadedly connected to one end of the connecting screw 902. The other end of the connecting screw 902 is threadedly connected to the second connecting nut 903, which is fixedly connected to the support chassis 904. The support chassis 904 is a conical disc, with its small end connected to the second connecting nut 903 and its large end in contact with the support ground.

[0069] The laser simulator 16 is connected to the simulator mounting plate 12, which is slidably connected to the slide rail. The simulator mounting plate 12 slides along the slide rail under the drive of the driving device. The driving device shown is a linear drive device, which can be an electric push rod.

[0070] The photoelectric detection mechanism signal testing support structure of this utility model, the drive device of the geared motor and the drive simulator mounting plate 12 are all controlled by the controller.

[0071] This utility model discloses a signal testing support structure for a photoelectric detection mechanism. A first support frame 1 and a second support frame 2 provide an installation and fixing environment for the photoelectric detection mechanism 17. A rotating disk 15 provides a component for manually applying rotational force to the photoelectric detection mechanism 17. A rotating bracket 4 provides an installation and movement platform for a laser simulator 16. During testing, the movement trajectory of the laser simulator 16 is controlled to simulate the target movement posture of the photoelectric detection mechanism 17, thus achieving target movement simulation. Different specifications of the first support frame 1 and the second support frame 2 are selected for support based on the main body diameter of the photoelectric detection mechanism 17 being tested. The length of the support base 5 can also be adjusted according to the main body length of the photoelectric detection mechanism 17 being tested, to accommodate photoelectric detection mechanisms 17 with different diameters and lengths. After the photoelectric detection mechanism 17 is fixed on the support frame, it can be manually rotated within a rotation angle range of -90° to +90° to detect signals from different rotational axes of the photoelectric detection mechanism 17 being tested.

[0072] During the target motion simulation, the laser simulator 16 is mounted on the simulator mounting plate 12, which is mounted on the rotating bracket 4. The rotating bracket 4 is connected to the reduction motor 3 via the connecting plate frame 6. When the reduction motor 3 is powered on, the rotating bracket 4 drives the laser simulator 16 to rotate in the horizontal plane. The laser simulator 16 emits a laser, and the detection system in the photoelectric detection mechanism 17 under test receives the signal, follows the laser movement of the laser simulator 16, and tracks it. Then, the micro camera in the photoelectric detection mechanism 17 outputs the signal of the detection system to determine whether the working state of the mechanism under test is normal.

[0073] This utility model's photoelectric detection mechanism signal testing support structure can automatically adjust its structural design parameters according to the diameter and length of the photoelectric detection mechanism 17 under test, providing a universal signal testing platform for different models of cylindrical photoelectric detection mechanisms 17. The photoelectric detection mechanism 17 can be rotated directly without disassembling it to change the direction of the test signal. The casters 7 allow for easy movement of the entire structure.

[0074] This utility model provides a signal testing support structure for photoelectric detection mechanisms, offering a universal and compatible signal testing platform for various models of photoelectric detection mechanisms 17. This platform allows for rapid reversal, easy assembly and disassembly, and convenient movement of signals along different axes. Compared to existing mechanism testing platforms, it offers stronger compatibility, more integrated functions, simpler operation, and higher testing efficiency, better meeting the testing needs of cylindrical photoelectric detection mechanisms.
