Description

Technical Field

[0001] This utility model relates to the technical field of titanium rod testing equipment, specifically a device for inspecting surface processing defects of titanium rods. Background Technology

[0002] Titanium rods are widely used in aerospace, medical and other fields. Surface processing defects can seriously affect performance and safety. Common surface processing defects include cracks, scratches, and sand holes. Therefore, it is necessary to inspect titanium rods for defects before they are used.

[0003] Currently, inspections are typically conducted manually, which is time-consuming and increases overall labor intensity. Furthermore, manual inspections can easily overlook defects, requiring repeated checks later. This is inconvenient and reduces the overall efficiency of titanium rod inspections. Utility Model Content

[0004] The purpose of this invention is to provide a device for inspecting surface defects of titanium rods, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for inspecting surface processing defects of titanium rods, comprising a base plate with a through-hole in the middle, a first sliding groove on both sides of the upper end of the base plate, a drive motor fixedly connected to the inner wall of one side of the through-hole, a gear fixedly connected to the output end of the drive motor, L-shaped sliding rods slidably connected in the first sliding grooves, a rack plate fixedly connected to the upper end of the sliding rods, the lower end of the rack plate meshing with the gear, and a mounting ring fixedly connected to the upper end of the rack plate via a bracket, a first electric telescopic rod symmetrically arranged fixedly connected to the inner wall of the mounting ring, an arc plate fixedly connected to the output end of the first electric telescopic rod, and an eddy current detector fixedly connected to the inner wall of the arc plate.

[0006] Preferably, the top plate is fixedly connected to the upper corner of the bottom plate by a bracket. A second sliding groove is opened on one side of the inner wall of the top plate. A support rod is fixedly connected to the side of the top plate away from the second sliding groove. A sliding plate is slidably connected in the second sliding groove. A limiting ring is fixedly connected to the lower end of the sliding plate and the support rod. A second electric telescopic rod is fixedly connected to both sides of the inner wall of the limiting ring. A clamping plate is fixedly connected to the output end of the second electric telescopic rod.

[0007] Preferably, the bottom plate is fixedly connected to the two corners on both sides.

[0008] Preferably, the inner walls of the clamps are all fixedly connected with soft pads, and the clamps are all arranged in a semi-circular shape.

[0009] Compared with the prior art, the beneficial effects of this utility model are: by setting a second sliding groove and a sliding plate in conjunction with a limiting ring, titanium rods of synchronous length can be fastened, increasing the overall detection flexibility and making clamping convenient. At the same time, during detection, the drive motor cooperates with the gear to mesh with the rack plate to move, thereby driving the eddy current detector inside the mounting ring to detect the titanium rod, increasing the overall detection efficiency.

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-5 This utility model provides a technical solution:

[0018] Example 1: A device for inspecting surface defects of titanium rods includes a base plate 1 with a through-hole in the middle, a first sliding groove 2 on both sides of the upper end of the base plate 1, and support feet fixedly connected to both sides of the lower end of the base plate 1. A top plate 3 is fixedly connected to the upper side of the base plate 1 through a bracket. A second sliding groove 4 is opened on one side of the inner wall of the top plate 3. A support rod 13 is fixedly connected to the side of the top plate 3 away from the second sliding groove 4, and a sliding plate 14 is slidably connected in the second sliding groove 4. A limiting ring 15 is fixedly connected to the lower end of the sliding plate 14 and the support rod 13. A second electric telescopic rod 16 is fixedly connected to both sides of the inner wall of the limiting ring 15. A clamping plate 17 is fixedly connected to the output end of the second electric telescopic rod 16. A soft pad is fixedly connected to the inner wall of the clamping plate 17, and the clamping plate 17 is semi-arc-shaped.

[0019] In use, the support legs drive the base plate 1 for stable support. When it is necessary to clamp the titanium rod for testing, the slide plate 14 is pushed according to the length of the titanium rod to be tested. The slide plate 14 slides inside the second slide groove 4. As the slide plate 14 drives the corresponding limit ring 15 to move to the appropriate position, the titanium rod is passed through the two limit rings 15. At this time, the second electric telescopic rod 16 is started by the external power supply. The output end of the second electric telescopic rod 16 drives the clamping plate 17 to move until the clamping plate 17 stably clamps both sides of the titanium rod, which is convenient for subsequent testing.

[0020] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a drive motor 5 is fixedly connected to the inner wall of one side of the through-hole; a gear 6 is fixedly connected to the output end of the drive motor 5; L-shaped slide rods 7 are slidably connected in the first slide groove 2; the upper ends of the slide rods 7 are all fixedly connected to a rack plate 8; the lower end of the rack plate 8 is meshed with the gear 6; and the upper end of the rack plate 8 is fixedly connected to a mounting ring 9 through a bracket; the inner wall of the mounting ring 9 is fixedly connected to a symmetrically arranged first electric telescopic rod 10; the output end of the first electric telescopic rod 10 is fixedly connected to an arc plate 11; and eddy current detectors 12 are fixedly connected to the inner wall of the arc plate 11.

[0021] In use, the drive motor 5 in the middle of the base plate 1 is started by an external power supply. The output end of the drive motor 5 drives the gear 6 to rotate inside the through-hole. When the gear 6 rotates, its upper end will mesh and drive the rack plate 8. The rack plate 8 moves stably under the sliding limit action of the first slide groove 2 and the slide rod 7. At the same time, the rack plate 8 will drive the mounting ring 9 to move through the bracket. Meanwhile, according to the specifications of the titanium rod being tested, the first electric telescopic rod 10 is started. The output end of the first electric telescopic rod 10 will drive the arc plate 11 to move continuously, thereby continuously closing the arc plate 11. The eddy current detector 12 on the arc plate 11 will continuously detect the titanium rod. When the detection coil on the eddy current detector 12, which carries an alternating current, approaches the surface of the titanium rod, an induced eddy current will be generated in the titanium rod. If there is a defect on the surface of the titanium rod, it will cause a change in the eddy current, which will cause a change in the impedance of the detection coil. The presence of a defect is determined by measuring the change in the impedance of the detection coil.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
