[0002] The grinding discs of a paper mill are key components in the pulping and papermaking process. They are mainly used for cutting, fracturing, and refining fibers, which directly affect the quality of pulp and the performance of paper.

[0003] In the existing technology, the side of the fan-shaped grinding disc needs to be processed by considering many factors such as the contour size, angle, and position of the mounting hole. That is, the side processing of the fan-shaped grinding disc needs to take into account multiple key factors to ensure its functionality and assembly accuracy. The traditional processing method is to use a template to lay out the lines and then process it after aligning the lines. This method is slow, has low accuracy, and sometimes requires repeated processing.

[0004] Therefore, it is very meaningful to provide a new type of tooling structure for processing fan-shaped grinding discs in paper mills. Utility Model Content

[0018] Figure 2 This is a schematic diagram of the fixed pressure plate structure provided in the disclosed embodiment of this utility model. Detailed Implementation

[0019] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of systems consistent with some aspects of this invention as detailed in the appended claims.

[0020] Traditional methods for processing the sides of grinding discs involve using templates to lay out lines, aligning the discs according to the lines, which is slow, inaccurate, and sometimes requires repeated processing. To address this, this implementation plan provides a tooling structure for processing fan-shaped grinding discs in a paper mill. The tooling includes: a frame column 1, a guide rod 2, a fixed pressure plate 3, a turntable 5, a fixed base plate 6, angle positioning pins 7, and locking bolts 8.

[0021] The turntable 5 is rotatably mounted on the fixed base plate 6 and rotates relative to the fixed base plate 6. The turntable 5 and the fixed pressure plate 3 have the same shape, both being fan-shaped, consistent with the shape of the fan-shaped grinding disc. The turntable 5 and the fixed pressure plate 3 are connected by multiple frame columns 1, forming a space for loading the fan-shaped grinding disc between the turntable 5 and the fixed pressure plate 3. The turntable 5 and the fixed pressure plate 3 are provided with guide rod mounting holes, and the distribution and number of the guide rod mounting holes are consistent with the mounting holes and number of the fan-shaped grinding disc to be tested. The grinding disc to be processed is placed in the space for loading the fan-shaped grinding disc, and the guide rod 2 passes through the guide rod mounting holes on the fixed pressure plate 3, the mounting holes of the fan-shaped grinding disc to be processed, and the guide rod mounting holes on the turntable 5 from top to bottom.

[0022] The fixed base plate 6 and the turntable 5 are provided with a shaft hole at their center, and a corresponding rotating shaft is provided in the shaft hole. The turntable 5 is rotatably mounted on the fixed base plate 6 through the rotating shaft, and the top end of the rotating shaft is lower than or flush with the upper surface of the fixed base plate 6.

[0023] The turntable 5 and the fixed pressure plate 3 are respectively provided with frame column mounting holes. Each frame column 1 is vertically installed between the turntable 5 and the fixed pressure plate 3 through the frame column mounting holes. There are three frame columns 1, and the corresponding frame column mounting holes are distributed at the two bottom corners of the fan-shaped turntable 5 and the fixed pressure plate 3 and the midpoint of the inner arc edge, respectively.

[0024] The surface area of ​​the turntable 5 and the fixed pressure plate 3 is larger than the area of ​​the fan-shaped grinding disc to be tested. When placed, the side of the fan-shaped grinding disc to be tested protrudes beyond the side of the turntable 5 and the fixed pressure plate 3. A special equipment is used to process the side of a group of grinding discs. Usually, 4-8 discs are placed as a group. The lower surface of the fixed pressure plate 3 abuts against the upper surface of the uppermost grinding disc to be processed. The outer arc edge 4 of the fan-shaped grinding disc to be tested is located inside the outer arc edge of the turntable 5. Positioning pin holes and bolt holes are respectively provided near the edge of the outer arc edge of the turntable 5. Angle positioning pins 7 and locking bolts 8 are installed in the positioning pin holes and bolt holes respectively, positioning the turntable 5 on the fixed base plate 6.

[0025] Using specialized equipment, mounting holes and frame column holes are machined on the turntable and fixed pressure plate. The positions of the mounting holes are consistent with the mounting holes on the grinding disc to be processed, and the concentricity of all holes on the turntable and fixed pressure plate is consistent. When using this fixture, after placing the grinding disc between the turntable and the fixed pressure plate, insert the guide rod to fix the mounting hole positions of all grinding discs, ensuring that the positions of all grinding disc mounting holes are uniform. Adjust the processing angle of the grinding disc by rotating the turntable, and install the angle positioning pin 7 and locking bolt 8 into the corresponding positioning pin holes and bolt holes. Position the turntable 5 on the fixed base plate 6, and use specialized equipment to process one side of the grinding disc. After processing one side, remove the angle positioning pin and unscrew the locking bolt 8. Manually rotate the turntable to the accurate position of the angle to be processed on the other grinding disc, insert the pin and lock the bolt to complete the processing of the other side. In this way, the processing of both sides of the grinding disc can be completed by rotating the fixture twice (the traditional processing method requires two processing runs on the machine tool, and only one disc can be processed at a time). This tooling can process multiple pieces in one go, which not only saves processing time, but also increases production efficiency by several times per unit time.

[0026] Other embodiments of the present invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of the invention are indicated by the claims.

[0027] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
