Technical Field

[0001] This utility model relates to the field of workpiece inspection technology, specifically a workpiece flatness visual recognition and inspection device. Background Technology

[0002] A workpiece generally refers to an item or part that has been processed, treated, repaired, or assembled during the manufacturing process. It can be any material that has been processed, including metal, plastic, wood, etc. It is usually part of a machine, equipment, or tool. The processing of a workpiece can be achieved through different technical means, such as turning, milling, drilling, grinding, etc. In order to meet the quality requirements of metal products, it is necessary to inspect the surface flatness during the processing.

[0003] Existing visual recognition and inspection equipment for workpiece flatness cannot adjust the inspection range according to the size of the workpiece. This makes it difficult to fully cover the entire surface of some larger workpieces, resulting in blind spots or omissions during the inspection process, which affects the overall inspection efficiency and accuracy.

[0027] 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.

[0028] Please see Figure 1-5In this embodiment of the present invention, a visual recognition and detection device for workpiece flatness includes two support frames 1. Each support frame 1 has a movable opening 2 on one side opposite to the other. A mounting frame 3 is fixedly connected to the top of both support frames 1. A telescopic assembly is provided on the top of the mounting frame 3, and a hollow strip 4 is provided on the telescopic assembly. Several abutment rods 5 slide through the top of the hollow strip 4, and an L-shaped pointer 11 is fixedly connected to the outer surface of the abutment rods 5. Several openings 6 are provided at the bottom of the hollow strip 4. A shielding frame 7 slides through both sides of the hollow strip 4. Movable openings 2 and 3 are provided on the surface and back of the mounting frame 3. A hollow plate 9 is fixedly connected to the bottom of both support frames 1. A bidirectional lead screw 10 is rotatably connected to one side of the inner wall of the hollow plate 9. A movable assembly is provided on the outer surface of the bidirectional lead screw 10, and a rotating assembly is provided at one end of the bidirectional lead screw 10. A hollow plate 2 12 is fixedly connected to the bottom of both support frames 1. A driving assembly is provided on the surface of the hollow plate 2 12, and a driving assembly is provided on one side of the inner wall of the hollow plate 2 12. A limiting component is provided, and a conveying component is set between the opposite sides of the two support frames 1. A motor 13 is mounted on the surface of one of the support frames 1 via a bracket. Several transparent scale frames 14 are fixedly connected to the top of the hollow strip 4. The surface of the transparent scale frames 14 is set with scale. The abutment rod 5 is T-shaped with a conical bottom end. Several abutment rods 5 slide through the top of the hollow strip 4 in a rectangular array, and several openings 6 are located directly below several abutment rods 5. The shielding frame 7 is inverted "L"-shaped, and the opposite sides of the two shielding frames 7 are attached to each other. The bottom ends of several abutment rods 5 abut against the top of the shielding frame 7. The moving port 1 2 and the moving port 2 8 are interconnected and have the same internal diameter. The width of the shielding frame 7 is the same as the internal diameter of the moving port 1 2. By adopting the above technical solution, the two shielding frames 7 can move outward along the inside of the hollow plate 9 according to the size of the workpiece to be inspected. In this way, the number of abutment rods 5 can be increased according to the size of the workpiece, thereby increasing the range of workpiece flatness inspection.

[0029] The telescopic assembly includes an electric telescopic rod 15 installed on the top of the mounting frame 3. The telescopic rod 15 slides through the interior of the mounting frame 3 and is fixedly connected to a connecting frame 16. The bottom of the connecting frame 16 is fixedly connected to the bottom of the hollow strip 4. By adopting the above technical solution, the hollow strip 4 can be driven to move downward, so that the bottom ends of several abutting rods 5 can abut against the surface of the workpiece, thereby enabling the flatness of the workpiece surface to be detected.

[0030] The moving assembly includes two moving bars 17 threadedly connected to the outer surface of the bidirectional lead screw 10. A sliding frame 18 is fixedly connected to the top of the moving bar 17. One side of the moving bar 17 slides through to the outside of the hollow plate 9, and the two sliding frames 18 are respectively located on opposite sides of the two support frames 1. The bottom of the shielding frame 7 is slidably connected to the inside of the sliding frame 18. The two moving bars 17 are respectively threadedly connected to two threads on the outer surface of the bidirectional lead screw 10.

[0031] The rotating assembly includes a rotating shaft 19 rotatably connected to one end of a bidirectional lead screw 10. One end of the rotating shaft 19 rotatably extends through the outside of the hollow plate 9 and is fitted with a gear 20.

[0032] The drive assembly includes a motor 21 mounted on one side of the hollow plate 2 12 via a bracket. A gear 22 is sleeved on the outside of the output end of the motor 21. The gear 22 meshes with the gear 1 20. By adopting the above technical solution, the meshing gear 22 can be reversed, which in turn drives the bidirectional lead screw 10 to reverse, thereby driving the two moving bars 17 and the sliding frame 18 to move away from each other, thus driving the two shielding frames 7 to move away from each other.

[0033] The limiting assembly includes a bidirectional lead screw 23 rotatably connected to one side of the hollow plate 12. Two pushers 24 are threadedly connected to the outer surface of the bidirectional lead screw 23. One side of the pusher 24 slides through the space between the two support frames 1 and is fixedly connected to a mounting frame 25. Several limiting rollers 26 are rotatably connected inside the mounting frame 25. Several flexible sleeves 27 are sleeved on the outer surface of the limiting rollers 26. The two pushers 24 are threadedly connected to two threads on the bidirectional lead screw 23. By adopting the above technical solution, the workpiece to be tested can be limited and clamped, avoiding the workpiece from shifting during the movement and affecting the test results.

[0034] The conveying assembly includes two conveying rollers 28 that rotate through one side of two support frames 1, and a conveyor belt 29 is fitted on the outer surface of the two conveying rollers 28.

[0035] The working principle of this utility model is as follows: In use, the number of abutment rods 5 is adjusted according to the size of the workpiece to be inspected. The workpiece is placed on the conveyor belt 29 between two mounting frames 25. Motor 21 is started, causing it to drive gear 22. Gear 22 drives the meshing gear 20 to reverse, which in turn drives the rotating shaft 19 to reverse. The rotating shaft 19 then drives the bidirectional lead screw 10 to reverse. At this time, the two moving bars 17 move away from each other as the bidirectional lead screw 10 rotates, thereby causing the two sliding frames 18 to move away from each other. This causes the two sliding frames 18 to drive the two blocking frames 7 to move outwards and gradually move out of the hollow bar 4, thus opening several openings 6 one by one. Simultaneously, the electric... The second motor 21 drives the second bidirectional lead screw 23 to rotate forward, causing the two push frames 24 to move closer to each other as the second bidirectional lead screw 23 rotates forward. This, in turn, drives the two mounting frames 25 to move to both sides of the workpiece until the flexible sleeve 27 on the limiting roller 26 is in contact with one side of the workpiece. At this time, the second motor 21 is turned off, so that several limiting rollers 26 and flexible sleeves 27 can limit and clamp the workpiece. Since the first gear 20 and the second gear 22 mesh with each other, the first gear 20 also stops rotating when the second motor 21 is turned off, thereby stopping the movement of the two blocking frames 7. At this time, the two blocking frames 7 open part of the opening 6, allowing the corresponding abutment rod 5 to pass through the hollow strip 4, thus enabling the adjustment of the number of abutment rods 5 used.

[0036] Then, start motor 13 to drive one of the conveyor rollers 28 to rotate at low speed, which in turn causes the conveyor belt 29 to rotate and transport the workpiece. At this time, the workpiece is clamped by several limiting rollers 26 and flexible sleeves 27 on the two mounting frames 25 to prevent it from shifting during movement. Subsequently, the workpiece will be transported by the conveyor belt 29 and come into contact with several abutment rods 5. The workpiece will push the abutment rods 5 to move upward, causing the abutment rods 5 to move the L-shaped pointer 11 in the transparent scale frame 14. At the same time, turn off motor 13. Then observe the change of the scale on the transparent scale frame 14 on one side of the L-shaped pointer 11 to detect the position, depth or height of the unevenness on the surface of the workpiece.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
