Technical Field

[0001] This utility model relates to the field of wire EDM machine guide wheel wear monitoring technology, specifically a detachable wire EDM machine guide wheel wear online monitoring device. Background Technology

[0002] Wear on the guide rollers of a wire EDM machine can cause deviations in the electrode wire's trajectory (such as wire shaking or jumping), directly affecting cutting accuracy and workpiece surface finish. Therefore, online monitoring is necessary to detect anomalies in real time and adjust process parameters (such as electrode wire tension and frequency conversion tracking) promptly to avoid the generation of batches of defective products.

[0003] The existing online monitoring device for guide wheel wear on wire EDM machines is fixed to the bearing part of the guide wheel with bolts. This method is inconvenient for subsequent disassembly and assembly, causing inconvenience to the operators.

[0004] Therefore, it is particularly important to design a detachable online monitoring device for the wear of guide wheels in wire EDM machines to overcome the above-mentioned technical defects and improve overall practicality. Utility Model Content

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0024] A detachable wire EDM machine guide wheel wear online monitoring device includes a connecting bracket 1. Compression springs 101 are symmetrically arranged on the top and bottom sides of the inner side of the connecting bracket 1. One end of each of the two sets of compression springs 101 on the same side is connected to a support plate 102. Pin rods 103 are connected to the top and bottom of the connecting bracket 1. Limiting protrusions 104 are symmetrically arranged on the left and right sides inside the connecting bracket 1. A connecting block 2 is inserted inside the connecting bracket 1. Connecting insertion holes 201 for the pin rods 103 are opened on the top and bottom of the connecting block 2. Limiting slots 202 that engage with the limiting protrusions 104 are symmetrically arranged on the left and right sides of the connecting block 2.

[0025] The connection between the connecting bracket 1 and the support plate 102 is a sliding connection. The top and bottom of the connecting bracket 1 are provided with through holes for the sliding of the pin rod 103. One end of the pin rod 103 is connected to an operating cap, and the other end of the pin rod 103 extends into the interior of the connecting bracket 1 and is fixedly inserted through the support plate 102. The connecting bracket 1 and the connecting block 2 are designed to be detachable. Screw holes are provided at the four corners on the back of the connecting bracket 1, and screws are provided inside the screw holes.

[0026] In this embodiment, please refer to Figure 3 A rotating seat 3 is fixed on one side of the connecting block 2. An adjusting arm 302 is rotatably connected to the top of the rotating seat 3 via a locking member 301. A clamping seat 303 is installed at the end of the adjusting arm 302 away from the rotating seat 3. A locking rod 304 is threadedly connected to the outside of the clamping seat 303. A fixing rod 305 is inserted inside the clamping seat 303. An industrial inspection camera 4 is installed on the top of the outside of the fixing rod 305.

[0027] The external size of the fixing rod 305 is adapted to the internal size of the clamping seat 303.

[0028] The working process of this utility model is as follows: In use, the connecting bracket 1 is fixedly installed on the guide wheel bearing. By pulling the pin rods 103 at both ends, the support plate 102 drives the compression spring 101 to retract. Then, the connecting block 2 is inserted, and the limiting slot 202 is engaged in the limiting protrusion 104. Then, the pin rod 103 is lowered to insert into the connecting socket 201, thus completing the fixation of the rotating seat 3. The placement position of the industrial inspection camera 4 is adjusted by adjusting the adjusting arm 302 and the fixing rod 305 inside the clamping seat 303. It is then fixed by the locking part 301 and the locking rod 304. The industrial inspection camera is fixed by the quick connection structure, which is convenient for disassembly and assembly, saves the time of the staff, and can adjust the placement position of the industrial inspection camera, so that the industrial inspection camera can periodically acquire images of the guide wheel surface. Then, the image processing algorithm is used to detect defects such as wear dents and cracks.
