[0006] The purpose of the utility model is to solve the problem in the prior art that although a workpiece can be inspected from multiple directions by multiple industrial cameras, when inspecting the bottom of the workpiece, the fixation of the workpiece needs to be released first, and personnel need to turn the workpiece over and re-place it before the bottom of the workpiece can be inspected, which is rather troublesome. A multi-directional inspection fixture is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A multi-directional inspection jig comprises an inspection platform and a workpiece, wherein the inner walls on both sides of the inspection platform are slidably connected with a lifting plate, the four corners of the bottom of the lifting plate are fixedly provided with fixing plates, one side of each of the four fixing plates is fixedly provided with a second industrial camera for inspecting the workpiece, the bottom center of the lifting plate is fixedly provided with a first industrial camera for inspecting the top of the workpiece, a placing platform for placing the workpiece is fixedly provided on the inner wall of the bottom of the inspection platform, the placing platform is located directly below the first industrial camera, a cylinder for adjusting the height of the lifting plate is fixedly provided on the top of the inspection platform, and the output end of the cylinder passes through the top of the inspection platform and is fixedly connected to the top of the lifting plate;

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Embodiment 1

[0031] Reference Figure 1-5 A multi-directional detection fixture is used in the field of detection fixtures, including: a detection table 1 and a workpiece 6. The detection table 1 serves as a main frame, and various mechanisms and equipment are arranged on it to achieve multi-directional detection.

[0032] On the inner walls on both sides of the inspection platform 1, we have slidably connected a lifting plate 3, and the four corners of the bottom of the lifting plate 3 are fixed with fixed plates 5. One side of the four fixed plates 5 is installed with a second industrial camera 10, which is used to inspect different sides of the workpiece 6. At the bottom center position of the lifting plate 3, we have fixedly set a first industrial camera 9, which is mainly used to inspect the top of the workpiece 6.

[0033] On the bottom inner wall of the inspection table 1 , we fixedly set a placement table 7 , which is located directly below the first industrial camera 9 and is used to stably place the workpiece 6 .

[0034] In order to adjust the height of the lifting plate 3, we fixed a cylinder 2 on the top of the inspection platform 1. The output end of the cylinder 2 passes through the top of the inspection platform 1 and is fixedly connected to the top of the lifting plate 3. By controlling the extension and retraction of the cylinder 2, we can easily adjust the height of the lifting plate 3 and the camera thereon to accommodate workpieces 6 of different sizes.

[0035] In addition to the above basic structure, this fixture is also equipped with a detection mechanism, a clamping mechanism and a lifting mechanism.

[0036] The detection mechanism mainly includes a third industrial camera 14 and a second electric push rod 13. A through hole 15 is opened at the center position of the placement table 7. The fixed part of the second electric push rod 13 is fixedly connected to the bottom inner wall of the detection table 1, and it is located in the through hole 15. The bottom of the third industrial camera 14 is fixedly connected to the telescopic part of the second electric push rod 13. In this way, by controlling the telescopic movement of the second electric push rod 13, we can make the third industrial camera 14 rise and fall, thereby realizing the detection of the bottom of the workpiece 6.

[0037] The clamping mechanism includes a cover body 11, a motor 12, a bidirectional screw rod 17 and two clamping plates 8. One side of the cover body 11 is slidably connected to the inner wall of one side of the detection platform 1, the motor 12 is fixed on one side of the cover body 11, and the two ends of the bidirectional screw rod 17 are respectively rotatably connected to the inner walls of the two sides of the cover body 11. The output end of the motor 12 is fixedly connected to one end of the bidirectional screw rod 17, and one side of the two clamping plates 8 is slidably connected to the inner wall of one side of the cover body 11, and they are all embedded with screw nuts, which are threadedly connected to the bidirectional screw rod 17. When the motor 12 is working, it will drive the bidirectional screw rod 17 to rotate, so that the two clamping plates 8 are close to or away from each other, thereby achieving clamping and releasing the workpiece 6.

[0038] The lifting mechanism mainly includes two first electric push rods 4. A groove 18 is provided on the bottom inner wall of the detection platform 1. The fixed parts of the two first electric push rods 4 are fixed on the bottom inner wall of the groove 18. The bottom of the cover body 11 is fixedly connected to the telescopic parts of the two first electric push rods 4. By controlling the telescopic movement of the first electric push rods 4, we can lift the cover body 11 and the clamping mechanism and workpiece 6 thereon, thereby facilitating the detection operation.

[0039] Embodiment 2

[0040] refer to Figure 1-5 , improved on the basis of the first embodiment:

[0041] In order to improve the stability and anti-slip property of the clamping, rubber pads are fixedly arranged on the sides of the two clamping plates 8 that are close to each other.

[0042] In addition, in order to improve the stability of the cover body 11 during the sliding process, a slide groove 16 is opened on the inner wall of one side of the detection platform 1, and a slider is fixedly set on one side of the cover body 11. One side of the slider is slidably connected to the inner wall of the slide groove 16, thereby effectively preventing the cover body 11 from shaking during the movement.

[0043] The working principles of the first industrial camera 9, the second industrial camera 10 and the third industrial camera 14 are the same as those of the authorization number CN217586972U, which will not be elaborated here. The first industrial camera 9, the second industrial camera 10 and the third industrial camera 14 are existing technologies and can of course be purchased as needed.

[0044] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 12, the first electric push rod 4, the first industrial camera 9, the second industrial camera 10, the second electric push rod 13 and the third industrial camera 14 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
