Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grinding, in particular to a ladle pin core grinding fixture. Background Art
[0002] A grinding fixture is a device used to fix a workpiece and grind it. During the grinding process, the main function of the fixture is to ensure the stability and accuracy of the workpiece and improve the grinding efficiency. Specifically, the fixture can accurately position and fix the workpiece to be ground, so that the workpiece maintains a stable position and posture during the grinding process, thereby ensuring the quality and accuracy of the grinding.
[0003] In the prior art, during the grinding process, the fixture needs to withstand large grinding forces and vibrations. If the design or manufacturing of the fixture is not good enough, the fixture may become loose, fall off or deform. If the fixture is not designed properly or operated improperly, there may be safety hazards. The installation, adjustment and disassembly of the existing fixture may be cumbersome, requiring the operator to have certain professional skills and experience. This not only reduces the operating efficiency, but also increases the risk of operating errors, thereby affecting the stability and reliability of grinding. In view of this, we propose a ladle pin core grinding fixture. Utility Model Content

[0006] Preferably, three groups of the fixing pins and connecting rods are provided, and the three groups of the fixing pins and connecting rods are in a circular array. The provision of the fixing pins and connecting rods ensures the fixing stability of the inner disk and the outer disk.
[0007] Preferably, an upper plate fixture is provided below the inner plate, and the upper plate fixture is sleeved in the through hole of the inner plate, so that the upper plate fixture is convenient for fixing the cylindrical insert.
[0008] Preferably, the V-shaped grooves are provided with 12 groups, which can grind 12 groups of cylindrical cores at the same time. Since the cylindrical cores are cylindrical and cannot be limited, an auxiliary design is matched with a contour device to ensure that the 12 cylindrical cores are against the contour device to ensure the parallelism of the grinding surface. This operation mode of against the contour device effectively ensures the parallelism of the grinding surface, avoids uneven grinding or errors caused by the incorrect position or tilt of the core, helps to improve the efficiency and quality of grinding, and makes the processed cylindrical cores have more consistent and smooth grinding surfaces. In addition, the use of the contour device can also reduce the labor intensity of the operator, improve the convenience and accuracy of the operation, simplify the adjustment and positioning steps in the grinding process, enable the operator to complete the grinding task more quickly, and reduce the errors caused by improper operation.
[0009] Preferably, the V-groove is 6+ / -0.1 degrees with the vertical direction, and is generally required to be 6±0.3 degrees after grinding. By designing the V-groove inclination angle to be 6±0.1 degrees, high precision is guaranteed.
[0010] Preferably, a grinding disc is provided between the cylindrical core and the upper disc jig. The grinding is usually composed of two parallel and relatively rotating discs, one of which is an outer disc 1 and is fixed, and the other grinding disc is driven to rotate by a motor. The cylindrical core is placed between the two discs and rotates with the rotation of the grinding disc. During the grinding process, a large amount of frictional heat is generated at the contact surface between the grinding disc and the cylindrical core, thereby softening the material on the surface of the cylindrical core, making it easier to grind and remove.
[0011] The utility model provides a ladle pin core grinding fixture, which has the following beneficial effects:
[0012] (1) The ladle needle core grinding fixture is designed with a V-groove with an inclination angle of 6±0.1 degrees to achieve high precision. The cylindrical core is fixed with a V-groove design to ensure the verticality of the core. The auxiliary height gauge effectively ensures the parallelism of the grinding surface, simplifies the adjustment and positioning steps during the grinding process, and enables the operator to complete the grinding task more quickly.
[0013] (2) The ladle needle core grinding fixture rotates with the rotation of the grinding disc through the provided grinding disc. During the grinding process, a large amount of friction heat is generated at the contact surface between the grinding disc and the cylindrical core, thereby softening the material on the surface of the cylindrical core, making it easier to be ground and removed.
