Description

Technical Field

[0001] The utility model belongs to the technical field of cutting and grinding devices, in particular to a cutting blade radial compensation component. Background Art

[0002] In the process of casting or die-casting, in order to fully fill the inside of the casting cavity and obtain high-quality castings, it is necessary to set up multiple burrs and runners. There will inevitably be residual materials around both sides of the casting, including risers and runners, also commonly known as water nozzles. After the casting or die-casting of the product is completed, in order to obtain a product that meets the regulations, it is necessary to remove the excess residual materials around the casting and the edge burrs generated during the casting or die-casting process; then the most important and labor-intensive part is to remove the residual materials. The traditional method is to cut and grind the connection between the residual materials and the casting so that it can be separated from the main body of the casting and fall off. However, there will inevitably be loss during the cutting process of the cutting blade, and the loss will cause the diameter of the cutting blade to decrease. When it is reduced to a certain amount, the reduction in its diameter cannot completely cut off the residual materials at the edge during the movement of the cutting blade, which will cause the residual materials to be difficult to fall off, and it is necessary to use manual secondary cutting or assistance to separate them. Summary of the invention

[0003] The utility model aims to provide a cutting blade radial compensation component, which is intended to solve the problem that the residual material cannot be fully cut and separated due to the wear and loss of the cutting blade.

[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:

[0005] A cutting blade radial compensation component comprises a cutting device, wherein the cutting device comprises a cutting blade and a cutting blade compensation component, wherein the cutting blade compensation component comprises a longitudinal reciprocating movement component and a distance sensor, wherein the distance sensor continuously or intermittently measures the diameter of the cutting blade, and the cutting blade compensation component drives the cutting device to approach a corresponding distance to a product to be processed according to a change in the diameter of the cutting blade.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the longitudinal reciprocating motion component includes a longitudinal drive motor and a longitudinal transmission component, the longitudinal transmission component includes a longitudinal driving pulley, a longitudinal driven pulley and a longitudinal transmission belt, and the base of the cutting device is fixedly connected to the horizontal section of the longitudinal transmission belt.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: it also includes a slide rail, the base is installed on the slide rail, and the horizontal section of the longitudinal transmission belt is parallel to the slide rail.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: a protective cover is arranged outside the cutting blade, a detection channel is opened on the protective cover, the distance sensor is fixed on the cutting device through a bracket, and its detection end detects the cutting blade through the detection channel.

[0009] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects: the diameter of the cutting blade is detected by a distance sensor, and the change in the radius of the cutting blade is obtained by the distance difference between two detections. The longitudinal reciprocating component drives the cutting device to move the difference, thereby compensating for the wear of the cutting blade, solving the problem of the inability to fully cut and separate the residual material due to the wear and loss of the cutting blade.
