[0002] A small inverter is a device used to change the speed of a motor. It controls the motor speed by changing the frequency of the power supply. The small inverter is small in size and is suitable for driving and controlling some small equipment. The clamping mechanism is a device commonly used in industrial production. It is mainly used to fix and position products for subsequent operations. Depending on different needs and application scenarios, the design and type of the clamping mechanism are also different.

[0003] After the production of small inverters is completed, a clamping mechanism is generally required to position the small inverters so that staff can check electrical parameters. The existing clamping mechanisms can clamp small inverters more stably.

[0004] However, the existing clamping mechanism does not have the function of clamping multiple small inverters at the same time, which results in the staff having to constantly load and unload materials when performing electrical parameter inspections, which is rather troublesome and seriously affects the detection efficiency of small inverters and cannot meet the detection needs. Therefore, a clamping mechanism for small inverter detection is proposed to solve the above-mentioned problems. Utility Model Content

To this end, one purpose of the utility model is to propose a clamping mechanism for small frequency converter detection, which solves the problem that the existing clamping mechanism does not have the function of clamping multiple small frequency converters at the same time, resulting in the need for staff to constantly load and unload materials when performing electrical parameter inspections, which is quite troublesome, seriously affecting the detection efficiency of small frequency converters and failing to meet detection needs.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The multi-block clamping mechanism includes a first clamping block fixedly connected to the inner side of a fixed frame, a placement plate and a sleeve rod, the outer surface of the sleeve rod is slidably connected to a movable clamping block and a second clamping block, a threaded hole is opened on the right side of the fixed frame, the internal thread of the threaded hole is connected to a threaded column, the front end of the threaded column is fixedly connected to the movable plate, and the rear end of the threaded column is fixedly connected to a rotating rod.

[0009] Furthermore, the first clamping block and the second clamping block are of the same size, and the number of the movable clamping blocks is three.

[0010] Furthermore, a cylinder is fixedly installed on the top of the frame, and an output shaft of the cylinder is fixedly connected to a lifting frame.

[0011] Furthermore, an electric telescopic rod is fixedly installed on the right side of the lifting frame, an output shaft of the electric telescopic rod is fixedly connected to a sliding block, and a camera device for appearance inspection is fixedly installed at the bottom of the sliding block.

[0012] Furthermore, a limit rod is fixedly connected to the inner side of the lifting frame, and the sliding block is slidably connected to the limit rod.

[0013] Furthermore, the front end of the movable plate abuts against the right side of the second clamping block, and the inner sides of the first clamping block, the movable clamping block and the second clamping block all abut against the side surface of the small inverter.

[0014] Furthermore, the bottom of the fixing frame and the frame are both fixedly connected to the top of the workbench, and a storage plate is fixedly connected to the inner side of the workbench.

[0015] The above solution of the utility model includes at least the following beneficial effects:

[0016] 1. The clamping mechanism for detecting small frequency converters is provided with multiple clamping mechanisms. When in use, the staff only needs to rotate the threaded column clockwise through the rotating rod to move the movable plate forward vertically, so that its front end abuts against the right side of the second clamping block, driving the second clamping block to move to the left, and then, with the cooperation of the first clamping block, the second clamping block and the three movable clamping blocks, four small frequency converters are clamped and fixed at the same time, so that the staff can check the electrical parameters at the same time, thereby reducing the number of loading and unloading times of the staff and improving the detection efficiency.

After the electrical parameter inspection is completed, the staff only needs to start the cylinder to drive the lifting frame to move downward, so that the camera device is close to the small inverter. When the camera device moves to a suitable height, the horizontal height of the lifting frame is kept unchanged. At this time, the electric telescopic rod is started to drive the camera device to move longitudinally through the sliding block, so that the appearance of four small inverters can be photographed one by one to confirm whether their wiring terminals are intact. There is no need for the staff to hold the camera device to take pictures, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The multi-block clamping mechanism includes a first clamping block 3, a placement plate 4 and a sleeve rod 5 fixedly connected to the inner side of the fixed frame 2. The outer surface of the sleeve rod 5 is slidably connected with a movable clamping block 6 and a second clamping block 7. A threaded hole 9 is opened on the right side of the fixed frame 2. The internal thread of the threaded hole 9 is connected with a threaded column 10. The front end of the threaded column 10 is fixedly connected with a movable plate 11, and the rear end of the threaded column 10 is fixedly connected with a rotating rod 12.

[0032] Among them, the first clamp block 3 and the second clamp block 7 are of the same size, the number of movable clamp blocks 6 is three, the front end of the movable plate 11 is against the right side of the second clamp block 7, and the inner sides of the first clamp block 3, the movable clamp block 6 and the second clamp block 7 are against the side of the small inverter 8.

[0033] When in use, the staff only needs to rotate the threaded column 10 clockwise through the rotating rod 12 to make the movable plate 11 move forward vertically, so that its front end abuts against the right side of the second clamping block 7, driving the second clamping block 7 to move to the left, and then with the cooperation of the first clamping block 3, the second clamping block 7 and the three movable clamping blocks 6, four small inverters 8 are clamped and fixed at the same time, so that the staff can check the electrical parameters at the same time, thereby reducing the number of loading and unloading times of the staff and improving the detection efficiency.

[0034] Embodiment 2:

[0035] See also Figure 1 On the basis of the first embodiment, a cylinder 14 is fixedly installed on the top of the frame 13, and the output shaft of the cylinder 14 is fixedly connected to the lifting frame 15. An electric telescopic rod 16 is fixedly installed on the right side of the lifting frame 15, and the output shaft of the electric telescopic rod 16 is fixedly connected to the sliding block 17. A camera device 18 for appearance inspection is fixedly installed at the bottom of the sliding block 17. Through the cooperation of the cylinder 14, the lifting frame 15, the electric telescopic rod 16, the sliding block 17 and the camera device 18, after the electrical parameter inspection is completed, the staff only needs to start the cylinder 14 to drive the lifting frame 15 to move downward, so that the camera device 18 is close to the small inverter 8. When the camera device 18 moves to a suitable height, the horizontal height of the lifting frame 15 is kept unchanged. At this time, the electric telescopic rod 16 is started, and the camera device 18 can be driven to move longitudinally through the sliding block 17, so that the appearance of the four small inverters 8 is photographed one by one to confirm whether their wiring terminals are intact, and then the staff does not need to hold the camera device 18 to take pictures, which is more convenient.

[0036] In this embodiment, a limiting rod 19 is fixedly connected to the inner side of the lifting frame 15, and the sliding block 17 is slidably connected to the limiting rod 19. By setting the limiting rod 19, the effect of limiting the sliding block 17 is achieved, thereby ensuring the stability of the sliding block 17 during lateral movement.

[0037] In addition, the bottom of the fixed frame 2 and the frame 13 are fixedly connected to the top of the workbench 1, and a storage board 20 is fixedly connected to the inner side of the workbench 1. By setting the storage board 20, it is convenient for the staff to place some items or tools in the space at the bottom of the workbench 1.

[0038] The working principle of the above embodiment is:

[0039] When in use, the staff first needs to place the four small frequency converters 8 on the side of the mobile clamping block 6 in sequence. At this time, the placement plate 4 can hold up the small frequency converter 8 to prevent it from falling. After the placement is completed, it is only necessary to rotate the threaded column 10 clockwise through the rotating rod 12 to make the movable plate 11 move forward vertically, so that its front end is against the right side of the second clamping block 7, driving the second clamping block 7 to move to the left, and then with the cooperation of the first clamping block 3, the second clamping block 7 and the three mobile clamping blocks 6, the four small frequency converters 8 are clamped and fixed at the same time, so that the staff can check the electrical parameters at the same time. Among them, after the electrical parameter check is completed, the staff only needs to start the cylinder 14 to drive the lifting frame 15 to move downward, so that the camera taking device 18 Approach the small frequency converter 8. When the camera device 18 moves to a suitable height, keep the horizontal height of the lifting frame 15 unchanged. At this time, start the electric telescopic rod 16, and the camera device 18 can be driven to move longitudinally through the sliding block 17, so as to perform appearance photography inspection on the four small frequency converters 8 one by one to confirm whether their wiring terminals are intact. In addition, when the appearance photography inspection is completed, it is necessary to reset the lifting frame 15 first, and then, by rotating the threaded column 10 counterclockwise through the rotating rod 12, the movable plate 11 can be moved away from the second clamping block 7, thereby releasing the clamping fixation of the small frequency converter 8. Subsequently, the staff can remove the four small frequency converters 8 from the inside of the fixing frame 2 one by one, and then replace them with the next batch of small frequency converters 8 that need to be inspected.

[0042] 2. The clamping mechanism for small inverter detection cooperates with the cylinder, lifting frame, electric telescopic rod, sliding block and camera device. After the electrical parameter inspection is completed, the staff only needs to start the cylinder to drive the lifting frame to move downward, so that the camera device is close to the small inverter. When the camera device moves to a suitable height, the horizontal height of the lifting frame is kept unchanged. At this time, the electric telescopic rod is started to drive the camera device to move longitudinally through the sliding block, so that the appearance of four small inverters can be photographed one by one to confirm whether their wiring terminals are intact.
