Description

Technical Field

[0001] This utility model relates to the field of testing electronic vacuum devices, specifically to a portable electronic vacuum transmitter testing platform. Background Technology

[0002] Vacuum electric transmitters are widely used in radar, communications, electronic warfare and other fields. Their performance testing requires parameter acquisition and analysis under various operating conditions.

[0003] Traditional testing platforms can only process a single transmitter at a time. The clamping process is time-consuming, and after the test is completed, it takes an equal amount of time to disassemble before the next device can be tested, which seriously slows down the overall progress. During the testing process, operators can only wait for the current device to finish testing and cannot clamp the next device simultaneously, resulting in a high idle rate at the workstation. In assembly line operation scenarios, this "single workstation, single device" mode will cause interruptions in the connection between upstream and downstream processes and affect the production line balance rate.

[0004] To address this, a portable electronic vacuum transmitter test platform is proposed. Utility Model Content

[0005] In view of the problems existing in the above-mentioned existing electric vacuum transmitter test platform, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a portable electric vacuum transmitter test platform, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A portable vacuum transmitter test platform includes a base, a rotating disk is provided above the base, a rotating shaft is fixedly provided at the center of the lower surface of the rotating disk, and the lower end of the rotating shaft is rotatably connected to the center of the top of the base. A drive mechanism connected to the rotating shaft is provided on one side of the top of the base.

[0009] The upper surface edge of the rotating disk is fixed with a plurality of evenly distributed clamping seats, and the top of each clamping seat is provided with a clamping groove, and the inside of the clamping groove is provided with a clamping mechanism.

[0010] A fixing frame is fixedly provided on one side of the base, and a cylinder is fixedly provided on the top of the fixing frame and above one of the clamping seats. A test head is fixedly provided on the moving end of the cylinder.

[0011] Preferably, the drive mechanism includes a motor fixedly mounted on the top of the base, the output shaft of the motor is fixedly provided with a first gear, and the shaft wall of the rotating shaft is fixedly provided with a second gear, the first gear and the second gear being meshed.

[0012] Preferably, the clamping mechanism includes a clamping plate disposed inside the clamping groove, a connecting rod fixedly disposed at the bottom of the clamping plate, a sliding groove provided at the bottom of the clamping groove, and a slider provided in the sliding groove, a telescopic rod fixedly disposed between the slider and the sliding groove, a spring sleeved on the wall of the telescopic rod, and the two ends of the spring being fixedly connected to the slider and the sliding groove respectively, and the end of the connecting rod away from the clamping plate being fixedly connected to the side wall of the slider.

[0013] Preferably, one side of the clamping groove extends through the side wall of the clamping seat, one side of the clamping groove is large in size, and the other side of the clamping groove is small in size.

[0014] Furthermore, the circumferential wall of the rotating disk is fixedly provided with a plurality of evenly distributed infrared emitters, and the inner side wall of the fixing frame is fixedly provided with an infrared receiver.

[0015] Preferably, a PLC controller is fixedly mounted on the side wall of the mounting bracket, and the drive mechanism, cylinder, test head, infrared transmitter, and infrared receiver are all electrically connected to the PLC controller.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. This utility model allows multiple transmitters to be clamped simultaneously by multiple clamping seats set on a rotating disk. The rotating disk is automatically rotated by a drive mechanism, so that the clamping, testing and unloading processes are carried out synchronously. For example, when the test head is testing equipment at a certain station, the operator can complete the clamping or unloading at other stations, avoiding waiting time at a single station. Compared with the traditional "single test, single installation" mode, the testing efficiency is improved.

[0018] 2. This utility model, through the clamping plate set in the clamping groove, and the clamping plate linked with the slider through the connecting rod, and the spring and telescopic rod providing elastic clamping force, can adapt to transmitter shells of different sizes. The large-sized opening on one side of the clamping groove facilitates the insertion of the equipment, and the small-sized limit on the other side ensures accurate positioning, making the assembly and disassembly of the electric vacuum transmitter more convenient.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-2 The portable vacuum transmitter test platform shown includes a base 1, a rotating disk 2 on top of the base 1, a rotating shaft 3 fixedly mounted at the center of the lower surface of the rotating disk 2, and the lower end of the rotating shaft 3 rotatably connected to the center of the top of the base 1. A drive mechanism connected to the rotating shaft 3 is provided on one side of the top of the base 1. The drive mechanism includes a motor 9 fixedly mounted on the top of the base 1. A first gear 10 is fixedly mounted on the output shaft of the motor 9, and a second gear 11 is fixedly mounted on the shaft wall of the rotating shaft 3. The first gear 10 and the second gear 11 are meshed. When the motor 9 works, it can drive the first gear 10 to rotate, and the first gear 10 can synchronously drive the second gear 11 to rotate, so that the rotating shaft 3 and the rotating disk 2 rotate together.

[0028] like Figure 3-4As shown, multiple evenly distributed clamping seats 4 are fixedly provided on the upper surface edge of the rotating disk 2. Each clamping seat 4 has a clamping groove 5 on its top. One side of the clamping groove 5 penetrates the side wall of the clamping seat 4. One side of the clamping groove 5 is larger than the other side. A clamping mechanism is provided inside the clamping groove 5. The clamping mechanism includes a clamping plate 12 disposed inside the clamping groove 5. A connecting rod 13 is fixedly provided at the bottom of the clamping plate 12. A sliding groove is provided at the bottom of the clamping groove 5, and a slider 14 is provided in the sliding groove. The slider 14 interacts with the sliding groove. A telescopic rod 15 is fixedly installed between the two sides. A spring 16 is sleeved on the wall of the telescopic rod 15, and the two ends of the spring 16 are fixedly connected to the slider 14 and the slide groove, respectively. The end of the connecting rod 13 away from the clamping plate 12 is fixedly connected to the side wall of the slider 14. When clamping, the clamping plate 12 is pulled outward, which causes the connecting rod 13 to pull the slider 14 outward. The slider 14 then pulls the telescopic rod 15 and the spring 16 outward. Under the action of the elastic force of the spring 16, the clamping plate 12 has the function of elastic clamping, so that the electric vacuum transmitter can be quickly clamped and fixed.

[0029] like Figure 1-2 As shown, a fixing frame 6 is fixedly provided on one side of the base 1. A cylinder 7 is fixedly provided on the top of the fixing frame 6 and above one of the clamping seats 4. A test head 8 is fixedly provided on the moving end of the cylinder 7. When the cylinder 7 extends, it can drive the test head 8 to move down and contact the clamped vacuum transmitter.

[0030] like Figure 1-2 As shown, multiple evenly distributed infrared emitters 17 are fixedly mounted on the circumferential wall of the rotating disk 2, infrared receivers 18 are fixedly mounted on the inner side wall of the mounting bracket 6, and a PLC controller 19 is fixedly mounted on the side wall of the mounting bracket 6. The drive mechanism, cylinder 7, test head 8, infrared emitters 17 and infrared receivers 18 are all electrically connected to the PLC controller 19.

[0031] First, the operator places the vacuum transmitter to be tested into the clamping seat 4 from the large-sized opening side of the clamping slot 5. The transmitter housing pushes the clamping plate 12 to move. The clamping plate 12 drives the slider 14 to compress the spring 16 and the telescopic rod 15 through the connecting rod 13. The elastic force of the spring 16 is used to achieve elastic clamping and fixing of the transmitter. The small-sized opening side restricts the displacement of the equipment to ensure accurate positioning.

[0032] Next, the PLC controller 19 starts the drive mechanism, the motor 9 drives the first gear 10 to rotate, and drives the rotating shaft 3 and the rotating disk 2 to rotate through the meshing second gear 11. The infrared emitter 17 on the circumferential wall of the rotating disk 2 rotates with the disk. When a certain clamping seat 4 moves to the test position below the fixed frame 6, the infrared receiver 18 detects the signal and feeds it back to the PLC controller, triggering the cylinder 7 to act.

[0033] Cylinder 7 drives test head 8 to descend vertically. The interface of test head 8 is precisely connected to the transmitter pin. PLC controller 19 applies test signals and collects parameters according to the preset program. At this time, the operator can clamp the next device on other clamping seats 4 or disassemble the already tested device, realizing the parallel clamping, testing and unloading processes.

[0034] After a single device is tested, cylinder 7 drives test head 8 to rise and reset. PLC controller 19 controls rotary table 2 to rotate again, moving the clamping seat 4 of the next station to the test position. The above test process is repeated. Rotation 2 continues to rotate in a cycle, so that multiple devices pass through the test position in sequence, realizing continuous automated testing.

[0035] The entire process forms a highly efficient cycle of "clamping-rotation-testing-unloading", which significantly improves the testing efficiency and automation level of the electric vacuum transmitter.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
