Description

Technical Field

[0001] The utility model relates to the technical field of grinding discs, and particularly relates to a grinding disc thickness detection device. Background Art

[0002] A grinding disc refers to a tool for grinding and processing samples with diamond abrasive grains or other abrasive grains, and can be processed into samples of various shapes and sizes. The grinding disc is widely used and can be applied to the grinding and processing of various materials such as metals, ceramics, plastics, glass, semiconductors, etc. The quality and preparation process of the grinding disc will directly affect the accuracy and reliability of the product. If there are defects on the surface of the grinding disc, or the abrasive grains are of different sizes, or the thickness is unqualified, it will affect the grinding effect. Therefore, after the grinding disc is produced and processed, it is necessary to detect its thickness and classify it.

[0003] After retrieval, a patent with the Chinese patent publication number CN219348511U discloses a floor grinding disc production detection mechanism, including a main body. A detection mechanism is fixed at the top of the main body. A test bench is fixed inside the main body relative to the detection mechanism. A grinding disc is arranged on the top of the test bench. A connection hole is formed through the surface of the grinding disc. An operation button is arranged on the surface of the main body. A detection positioning mechanism is arranged on the top of the test bench. A dust prevention mechanism is arranged on the surface of the operation button. Through the designed fixed rod, the utility model can quickly dock the grinding disc with the test bench for positioning. At the same time, in cooperation with the designed chute, slider, guide hole and guide rod, the position of the positioning block can be adjusted according to the size of the grinding disc, so as to facilitate screwing the positioning rod for extrusion positioning. Compared with the existing technology, it greatly facilitates the detection work of the detection mechanism on the grinding disc.

[0004] Aiming at the problems in the above technology that the thickness of the grinding disc is not detected, and the unqualified grinding discs are not marked and distinguished after detection; for this reason, a grinding disc thickness detection device is proposed. Content of the Utility Model

[0005] In view of this, the embodiments of the utility model hope to provide a grinding disc thickness detection device to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0006] The technical solution of the embodiment of the present utility model is realized as follows: It includes a workbench, on one side of the top end of the workbench, a supporting side plate is fixedly installed, which is convenient for overall control of the detection device. In the middle of the other side of the workbench, a control box is provided. The interior of the workbench is hollow. On the top end of the workbench, a clamping assembly is provided. In the middle of the bottom end of the workbench, a driving motor is fixedly installed. On one side of the top end of the supporting side plate, a paint cylinder is fixedly installed. On the other side of the top end of the supporting side plate, a first cylinder is fixedly installed, and a detection frame is fixedly installed at the movable bottom end of the first cylinder. At the bottom end of the supporting side plate, a storage cylinder is fixedly installed, and one end of the storage cylinder is fixedly connected to a spray nozzle. At the bottom end of the outer wall of the other end of the supporting side plate, a support rod is fixedly installed, and a second cylinder is fixedly installed at the top end of the support rod. The movable end of the second cylinder is located inside the storage cylinder. If the thickness of the grinding disc is qualified, take away the grinding disc and continue to detect the next grinding disc. If the thickness of the grinding disc is unqualified, the second cylinder extends to spray the paint between one end stored inside the storage cylinder and the rubber sleeve from the spray nozzle to the top end of the grinding disc, so as to mark the grinding disc with unqualified thickness for distinction.

[0007] In some embodiments, the clamping assembly includes three fixed rods, and the three fixed rods are equally angularly distributed. At the upper end of the circumference of the three fixed rods, a clamping rod is fixedly installed. At the lower end of the circumference of the three fixed rods, a driven gear is fixedly installed. The three clamping rods are cam-shaped.

[0008] In some embodiments, a driving gear is fixedly installed at the output end of the driving motor, and the outer circumference of the driving gear meshes with the outer circumference of the three driven gears. When the grinding disc is placed on the top end of the workbench, the driving motor works, and the three driven gears are driven to rotate simultaneously by the driving gear, so as to push the three clamping rods to move the grinding disc at the same time, achieving the effect of centering the grinding disc. At the same time, the three clamping rods also clamp the grinding disc during the thickness detection of the grinding disc, avoiding the displacement of the grinding disc during the thickness detection process and affecting the detection result.

[0009] In some embodiments, a reinforcing frame is fixedly installed between the outer wall of the top end of the detection frame and the circumferential outer wall of the movable bottom end of the first cylinder to further improve the stability of the up and down movement of the detection frame, and the detection frame is located above the center of the clamping assembly.

[0010] In some embodiments, a guide pipe is fixedly connected between the interior of the storage cylinder and the outlet end of the paint cylinder to transfer the paint to the interior of the storage cylinder. A rubber sleeve is fixedly installed inside the storage cylinder. The rubber sleeve is hemispherical, and the rubber sleeve is located at the other end of the outlet end of the guide pipe. When the movable end of the second cylinder is pushed to the rubber sleeve and pushed out, the paint between one end stored inside the storage cylinder and the rubber sleeve can be sprayed from the spray nozzle to the top end of the grinding disc, so as to mark the grinding disc with unqualified thickness for distinction.

[0011] In some embodiments, a pressing plate is provided at the bottom end of the detection frame, and a telescopic mechanism is fixedly installed between the bottom end of the detection frame and the top end of the pressing plate, so as to prevent the pressing plate from directly colliding with the top end of the grinding disc, which not only affects the service life of the pressing plate, but also affects the flatness of the bottom end of the pressing plate after a long time, thereby affecting the detection result. A plurality of infrared rangefinders are fixedly installed on the outer circumference of the pressing plate at equal angles, and a wear-resistant and compression-resistant coating is provided on the outer wall of the pressing plate.

[0012] In some embodiments, the spray nozzle is located above the clamping assembly.

[0013] Due to the adoption of the above technical solutions in the embodiments of the present invention, it has the following advantages:

[0014] 1. For the grinding disc thickness detection device, if the thickness of the grinding disc is qualified, the grinding disc is taken away and the next grinding disc is continued to be detected. If the thickness of the grinding disc is unqualified, the second cylinder extends to spray the pigment between the inner end of the storage cylinder and the rubber sleeve from the spray nozzle to the top end of the grinding disc, thereby marking the grinding disc with unqualified thickness for easy distinction, avoiding the unqualified grinding discs from flowing into the market due to the mixing or chaotic placement of multiple grinding discs.

[0015] 2. For the grinding disc thickness detection device, when the grinding disc is placed on the top end of the workbench, the drive motor works, and the three driven gears are driven to rotate simultaneously by the driving gear, so that the three clamping rods simultaneously push the grinding disc to achieve the effect of centering the grinding disc. At the same time, the three clamping rods also clamp the grinding disc during the thickness detection of the grinding disc, avoiding the displacement of the grinding disc during the thickness detection process and affecting the detection result.
