Description

Technical Field

[0001] This utility model relates to the field of flatness detection technology, specifically to a flatness detection mechanism for top cover skin. Background Technology

[0002] Roof skin refers to the outer shell component covering the top of vehicles such as cars, trains, or airplanes. It serves multiple functions, including protecting the internal structure, reducing air resistance, waterproofing, and enhancing the appearance. It possesses high strength and toughness, capable of withstanding certain external impacts. Its cost is relatively low, and it is easy to process and shape, such as stamping into various forms. It is widely used in the roof skins of some trucks because trucks have relatively lower requirements for streamlined appearance and prioritize structural robustness.

[0003] The roof panel needs to be precisely assembled with components such as the body frame and side panels. If the flatness does not meet the requirements, such as the presence of local bulges or depressions, it will lead to uneven assembly gaps between the panel and other components. To prevent this, flatness inspection is required. Existing inspection devices often require manual inspection at various locations, which is not only labor-intensive but also prone to missed inspections or inaccurate results. Therefore, we propose a roof panel flatness inspection mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a top cover skin flatness detection mechanism to solve the problems mentioned in the background art, such as the inconvenience of conducting all-round, blind-angle detection of the top cover skin and the inability to maintain stability during the detection process, which greatly reduces the accuracy of the device in detecting the top cover skin.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a top cover skin flatness detection mechanism, comprising: a main board, a clamping mechanism fixedly connected to the top of the main board, and a reciprocating mechanism fixedly connected to the top of the main board.

[0006] The clamping mechanism includes an air pump. The air pump is fixedly connected to the bottom of the main board, a push rod is fixedly connected to the top of the air pump, a shelf is fixedly connected to the top of the push rod, a horizontal plate is fixedly connected to the top of the main board, a sliding groove is opened inside the horizontal plate, the top of the sliding groove is slidably connected to the bottom of the shelf, and a detection table is fixedly connected to the top of the shelf.

[0007] The shelf is fixedly connected to a fixed frame at the top, the fixed frame is fixedly connected to a connecting frame at the top, a cylinder is fixedly connected inside the connecting frame, a telescopic rod is slidably connected inside the cylinder, an adjusting shaft is rotatably connected to one side of the telescopic rod, a connecting rod is rotatably connected to one side of the connecting frame, and a clamping rod is rotatably connected to one side of the connecting rod.

[0008] The bottom of the clamping rod is fixedly connected to an anti-slip pad, which is made of rubber.

[0009] The reciprocating mechanism includes a top plate, a top plate is fixedly connected to the top of the main board, a motor is fixedly connected to the top of the top plate, a threaded rod is rotatably connected to one side of the motor, a threaded sleeve is installed on the outer thread of the threaded rod, a fixed plate is fixedly connected to one end of the threaded sleeve, and a detector is fixedly connected to the other end of the threaded sleeve.

[0010] The top plate has a slide rail inside, and a slider is slidably connected inside the slide rail. One end of the slider is fixedly connected to the other end of the fixed plate.

[0011] The motherboard has a support rod fixedly connected to its bottom, and a base is fixedly connected to the bottom of the support rod.

[0012] This utility model has at least the following beneficial effects:

[0013] In use, this invention utilizes a clamping mechanism that replaces the manual fixing required for testing with an air pump that drives the shelf to slide within the groove via a push rod. This allows the top cover to reciprocate laterally via the testing platform. Furthermore, the clamping rods are brought close together to secure the top cover, ensuring stability during testing. The reciprocating mechanism allows the operator to start the motor, which rotates the threaded sleeve via a threaded rod. This, in turn, drives the detector to perform lateral testing of the top cover, making the testing more comprehensive and preventing undetected blind spots. Attached Figure Description

[0019] 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.

[0020] Example 1

[0021] Please see Figure 1-4 This utility model provides a technical solution: a top cover skin flatness detection mechanism, including: a main board 1, a clamping mechanism 2 fixedly connected to the top of the main board 1, and a reciprocating mechanism 3 fixedly connected to the top of the main board 1. In use, the clamping mechanism 2 changes the original manual fixing for detection to air pump 201 driving the shelf 204 to slide inside the slide groove 203 via push rod 206. At this time, the top cover skin can be driven by the detection table 205 to perform lateral reciprocating detection. In addition, the clamping rods 213 move closer together to fix and clamp the top cover skin, keeping the device stable during the detection process. Through the reciprocating mechanism 3, when the device is in use, the operator starts the motor 302 to drive the threaded sleeve 304 to rotate via threaded rod 303. The threaded sleeve 304 drives the detector 103 to perform lateral detection on the top cover skin, making the device more comprehensive in the detection process and preventing blind spots from being detected.

[0022] The clamping mechanism 2 includes an air pump 201. The air pump 201 is fixedly connected to the bottom of the main board 1. A push rod 206 is fixedly connected to the top of the air pump 201. A shelf 204 is fixedly connected to the top of the push rod 206. A horizontal plate 202 is fixedly connected to the top of the main board 1. A sliding groove 203 is provided inside the horizontal plate 202. The top of the sliding groove 203 is slidably connected to the bottom of the shelf 204. A detection table 205 is fixedly connected to the top of the shelf 204. A fixing frame 2 is fixedly connected to the top of the shelf 204. 07. A connecting frame 209 is fixedly connected to the top of the fixed frame 207. A cylinder 208 is fixedly connected inside the connecting frame 209. A telescopic rod 210 is slidably connected inside the cylinder 208. An adjusting shaft 212 is rotatably connected to one side of the telescopic rod 210. A connecting rod 211 is rotatably connected to one side of the connecting frame 209. A clamping rod 213 is rotatably connected to one side of the connecting rod 211. An anti-slip pad 214 is fixedly connected to the bottom of the clamping rod 213. The anti-slip pad 214 is made of rubber.

[0023] When using the device, the operator starts the air pump 201, which drives the shelf 204 to slide inside the slide groove 203 via the push rod 206. At this time, the detection position of the top cover skin can be adjusted by the vertical movement of the detection table 205. In addition, the telescopic rod 210 is extended and retracted by the cylinder 208, and the two sets of connecting rods 211 and clamping rods 213 are opened and closed by the adjusting shaft 212, which can clamp and fix the top cover skin to prevent displacement during the detection process. In addition, the two sets of anti-slip pads 214 can prevent marks from being left on the top cover skin when clamping it, thus improving the safety of the device's detection.

[0024] The reciprocating mechanism 3 includes a top plate 301. The top plate 301 is fixedly connected to the top of the main plate 1. A motor 302 is fixedly connected to the top of the top plate 301. A threaded rod 303 is rotatably connected to one side of the motor 302. A threaded sleeve 304 is threadedly installed on the outer periphery of the threaded rod 303. A fixed plate 306 is fixedly connected to one end of the threaded sleeve 304, and a detector 103 is fixedly connected to the other end of the threaded sleeve 304. A slide rail 305 is provided inside the top plate 301. A slider 307 is slidably connected inside the slide rail 305. One end of the slider 307 is fixedly connected to the other end of the fixed plate 306. When the device is in use, the operator starts the motor 302, which drives the threaded sleeve 304 to move laterally outside the threaded rod 303 through the threaded rod 303. At this time, the detector 103 is driven by the threaded sleeve 304 to perform lateral movement detection on the top cover skin. In addition, the slider 307 installed on one side of the fixed plate 306 slides inside the slide rail 305, which improves the smoothness of the detection process of the device.

[0025] Example 2

[0026] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that a support rod 101 is fixedly connected to the bottom of the main board 1, and a base 102 is fixedly connected to the bottom of the support rod 101 to prevent the measurement accuracy from being affected by external vibration or deformation of its own structure during the detection process.
