Description

Technical Field

[0001] This utility model relates to the field of magnetic particle testing technology, and in particular to a magnetic particle testing operation platform. Background Technology

[0002] Magnetic particle testing is a non-destructive testing method based on electromagnetic principles. It uses magnetized ferromagnetic materials and the leakage magnetic field to attract magnetic particles and form visible magnetic traces, thereby detecting discontinuities such as cracks and inclusions on and near the surface of the material.

[0003] As described in announcement number CN206583851U, a mobile magnetic particle testing operating platform includes a platform operating plate and a support plate. The platform operating plate is mounted on the support plate, and a horizontal plate is erected between the support plates. A connector is provided at the connection between the platform operating plate and the support plate, and the support plate and the horizontal plate are connected by the connector. The platform operating plate is equipped with a detachable insulating head one, an insulating head two, and a hand crank arm. In this novel platform, the operating plate, support plate, and horizontal plate are all connected by connectors, which not only facilitates assembly but also makes disassembly after use convenient. It requires less space during transport, reducing space limitations when moving the entire operating platform. The platform can also be extended by connecting connectors to facilitate the measurement of longer workpieces. The insulating heads can be heightened by extension blocks to facilitate the measurement of wider workpieces. The threaded connection of the hand crank arm ensures the insulating heads are tightly clamped together, making operation convenient.

[0004] This patent allows for connection via connectors, but existing operating platforms do not have height-adjustable functionality, which makes it very inconvenient for operators of different heights to perform magnetic particle testing, and the flexibility of use needs to be improved. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing operating platforms do not have height-adjustable functionality, which makes it very inconvenient for operators of different heights to perform magnetic particle testing, and the flexibility of use needs to be improved.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a magnetic particle testing operation platform, comprising an operation platform body, a height adjustment component connected to the bottom of the operation platform body, the height adjustment component comprising a base plate, universal wheels connected to the four corners of the bottom of the base plate, support frames connected to both sides of the base plate, a servo motor connected to the surface of the operation platform body near one set of support frames, a worm gear connected to the output end of the servo motor, worm wheels inserted inside both sets of support frames, a one-way screw fixedly connected to the top of the worm wheels, a lifting frame connected to the surface of both sets of one-way screws, sleeves connected to the four corners of the top of the base plate, a lifting column provided inside each set of sleeves, and a top plate fixedly connected to the top of the lifting frame.

[0007] Furthermore, the outer surface of the lifting column is in contact with the inner wall of the sleeve, and a sliding connection is formed between the lifting column and the sleeve.

[0008] Furthermore, the position and size of the worm are matched with the position and size of the worm wheel, and the worm and the worm wheel form a meshing connection.

[0009] Furthermore, the one-way screw and the lifting frame form a threaded connection.

[0010] Furthermore, the bottom surface of the main body of the operating platform is provided with a disassembly and assembly component, the disassembly and assembly component includes a groove, and slots are provided inside both sides of the main body of the operating platform, and threaded rods are inserted into the interior of both sets of slots.

[0011] Furthermore, a threaded rod is fixedly connected to the rear end of the threaded rod, and a bearing sleeve is connected to the surface of the threaded rod near the throttle.

[0012] Furthermore, the threaded rod has a locking block threadedly connected to its surface, and the outer surfaces of both sides of the top plate are provided with locking grooves. The locking block is L-shaped.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when the height of the operating platform body needs to be adjusted, a servo motor can be started, driving the worm gear to rotate through its output end. The worm gear and worm wheel form a transmission relationship through meshing, thereby driving the one-way screw to rotate threadedly. Under the action of the threaded pair, the operating platform body smoothly rises and falls along the screw axis until it is adjusted to a suitable height. This can adapt to the usage needs of operators of different heights, ensuring that they maintain a comfortable operating posture when performing magnetic particle inspection, while ensuring full contact between the magnetic pole and the workpiece surface, thereby improving inspection accuracy and efficiency.

[0015] 2. In this utility model, the main body of the operating platform and the height adjustment component can be disassembled separately during transportation. The separation can be completed simply by turning the handle to pull out the locking block, thus avoiding the inconvenience of transporting a one-piece operating platform.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, such as Figure 1 - Figure 3As shown, this utility model provides a magnetic particle testing operation platform, including an operation platform body 1. A height adjustment component 2 is connected to the bottom of the operation platform body 1. The height adjustment component 2 includes a base plate 201. Universal wheels 202 are connected to the four corners of the bottom of the base plate 201. Support frames 203 are connected to both sides of the base plate 201. A servo motor 204 is connected to the surface of the operation platform body 1 near one set of support frames 203. A worm gear 205 is connected to the output end of the servo motor 204. Worm wheels 206 are inserted into the interior of both sets of support frames 203. A one-way screw 2 is fixedly connected to the top of the worm wheel 206. 07. Lifting frames 208 are connected to the surfaces of both sets of one-way screws 207. Sleeves 209 are connected to the four corners of the top of the base plate 201. Lifting columns 210 are installed inside each set of sleeves 209. A top plate 211 is fixedly connected to the top of the lifting frame 208. The outer surface of the lifting column 210 is in contact with the inner wall of the sleeve 209. A sliding connection is formed between the lifting column 210 and the sleeve 209. The position and size of the worm 205 match the position and size of the worm wheel 206. A meshing connection is formed between the worm 205 and the worm wheel 206. A threaded connection is formed between the one-way screw 207 and the lifting frame 208.

[0024] The effect achieved in Embodiment 1 is that when the height of the main body 1 of the operating platform needs to be increased, the reverse function of the servo motor 204 can be activated, so that the output end of the servo motor 204 can drive the worm gear 205 to reverse. When the worm gear 205 reverses, it will also mesh and rotate in the opposite direction with the two sets of worm gears 205 at the same time. In this way, through the reverse meshing connection, the two sets of one-way screws 207 can reverse simultaneously, so that the one-way screws 207 can rotate in the opposite direction with the lifting frame 208. Through the reverse screw rotation, the two sets of lifting frames 208 can be driven to push the top plate 211 to rise. At the same time, the four sets of lifting columns 210 will also slide in the four sets of sleeves 209 under the drive of the top plate 211, improving the height of the platform. The stability during lifting and lowering is ensured, thereby raising the main body 1 of the operating platform. Once the main body 1 of the operating platform has risen to a suitable height, the servo motor 204 can be turned off to stop the lifting of the main body 1 of the operating platform. When it is necessary to lower the height of the main body 1 of the operating platform, the forward rotation function of the servo motor 204 can be activated, causing the worm gear 205 and worm wheel 206 to mesh and rotate in the forward direction, driving the two sets of one-way screws 207 to rotate in the forward direction at the same time. By rotating the screws in the forward direction, the height of the main body 1 of the operating platform can be lowered, which can adapt to the usage needs of operators of different heights, ensuring that they maintain a comfortable operating posture when performing magnetic particle inspection, while ensuring full contact between the magnetic pole and the workpiece surface, thereby improving the inspection accuracy and efficiency.

[0025] Example 2, as Figure 1 and Figure 4As shown, the bottom surface of the main body 1 of the operating platform is provided with a disassembly and assembly component 3. The disassembly and assembly component 3 includes a groove 301. The inside of both sides of the main body 1 of the operating platform is provided with slots 302. Threaded rods 303 are inserted into the inside of both sets of slots 302. The rear end of the threaded rods 303 is fixedly connected to the threaded rods 303. A bearing sleeve 305 is connected to the surface of the threaded rods 303 near the throttle 304. A locking block 306 is threadedly connected to the surface of the threaded rods 303. The outer surfaces of both sides of the top plate 211 are provided with locking grooves 307. The locking block 306 is L-shaped.

[0026] The effect achieved in Embodiment 2 is that, during transport, the forward rotation of the handle 304 drives the threaded rod 303 to rotate forward. When the threaded rod 303 rotates forward, it will rotate in the forward thread with the locking block 306, thereby causing the locking block 306 to retract into the slot 302 and allowing the locking block 306 to be pulled out from the slot 307. After removing both sets of locking blocks 306, the main body of the operating platform 1 can be lifted upward to complete the separation and disassembly from the height adjustment component 2. When installation is required, the groove 301 of the main body of the operating platform 1 can be aligned with the top plate 211, and then the handle 304 can be reversed to insert the locking block 306 into the slot 307 for fixation.

[0027] Working Principle: When the height of the operating platform body 1 needs to be adjusted, the servo motor 204 can be started, driving the worm gear 205 to rotate through its output end. The worm gear 205 and the worm wheel 206 are connected by meshing to form a transmission relationship, which in turn drives the one-way screw 207 to rotate. Under the action of the threaded pair, the operating platform body 1 can be smoothly raised and lowered along the screw axis until it is adjusted to a suitable height. It can adapt to the usage needs of operators of different heights, ensuring that they maintain a comfortable operating posture when performing magnetic particle inspection, while ensuring full contact between the magnetic pole and the workpiece surface, thereby improving the inspection accuracy and efficiency. When transporting, the operating platform body 1 and the height adjustment component 2 can be separated. Simply turn the handle 304 to pull out the locking block 306 to complete the separation, avoiding the inconvenience of transporting the integrated operating platform body 1.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
