Description

Technical Field

[0001] The invention belongs to the field of mechanical processing of refractory materials, and in particular relates to a processing method for ensuring smooth connection between an arc and a plane of the refractory material. Background Art

[0002] In the substrate glass industry, a large number of refractory materials of various specifications need to be processed and used. The refractory materials themselves are relatively hard, and ordinary tools cannot meet the use requirements. Only customized tools such as diamond tools can be used. During the processing, only a small amount of cutting can be used for grinding, and the wear of the tools is also relatively serious. There are errors in tool production, workpiece production, workpiece clamping, and tool setting. If the theoretical value is used for processing when processing arc angles, overcutting will occur at the intersection of the arc surface and the plane, and edges and corners will appear. The equipment has high requirements for accuracy and no edges and corners are allowed, especially at the intersection of the installation plane and the arc. The plane and the arc surface are required to be smoothly connected. In actual processing, depressions and edges and corners often appear here, which leads to the failure of equipment accuracy to meet the use requirements. Summary of the invention

[0003] The purpose of the present invention is to provide a processing method for ensuring smooth connection between the circular arc and the plane of the refractory material, so as to solve the problem of angular edges existing at the intersection of the circular arc and the plane during the processing of the existing refractory material.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: In a first aspect, a processing method for ensuring smooth connection between an arc and a plane of a refractory material comprises the following steps: S1: Move the tool to the upper surface of the refractory material to be processed, maintain a first preset gap between the tool and the upper surface, put a feeler gauge of standard thickness into the first preset gap, slowly move the tool downward until the feeler gauge of standard thickness has resistance when sliding, complete the tool setting of the upper surface of the refractory material to be processed and calculate the tool setting error value of thickness, and compensate the tool setting error value of thickness into the machine tool; S2: adding a first adjustment amount to the tool setting error value of the thickness to obtain a first machining allowance, and compensating the first machining allowance into the machine tool; S3: moving the tool to the side of the refractory material to be processed, maintaining a second preset gap between the tool and the side, placing a feeler gauge of standard thickness into the second preset gap, slowly moving the tool to the side until the feeler gauge of standard thickness has resistance when sliding, completing the side tool setting of the refractory material to be processed and calculating the tool setting error value of the width, and compensating the tool setting error value of the width into the machine tool; S4: adding a second adjustment amount to the tool setting error value of the width to obtain a second machining allowance, and compensating the second machining allowance into the machine tool; S5: Start the machine tool and move the tool close to the side surface at a preset step distance until scratches appear on the side surface and then stop feeding. Restart the machine tool to process the arc of the refractory material to be processed. After the processing is completed, the arc of the refractory material to be processed smoothly connects the upper surface and the side surface.

[0005] In some embodiments, the first preset gap is greater than 0.2 mm and less than 0.3 mm.

[0006] In some embodiments, the second preset gap is greater than 0.2 mm and less than 0.3 mm.

[0007] In some embodiments, the standard thickness feeler gauge has a thickness of 0.1 mm.

[0008] In some embodiments, the first adjustment amount is 0.02 mm to 0.05 mm.

[0009] In some embodiments, the second adjustment amount is 0.05 mm to 0.1 mm.

[0010] In some embodiments, the preset step distance is 0.02 mm.

[0011] In some embodiments, the step of maintaining a first preset gap between the tool and the upper surface specifically includes: the distance between a tangent line of a tool arc of the tool and the upper surface is the first preset gap.

[0012] In some embodiments, the step of maintaining a second preset gap between the tool and the side surface specifically includes: the distance between the side surface of the tool and the side surface of the refractory material to be processed is the second preset gap.

[0013] In some embodiments, before the machine tool is restarted to machine the arc of the refractory material to be machined, the error values ​​of the thickness and width of the refractory material to be machined are measured and input into the machine tool.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a processing method for ensuring smooth connection between the circular arc and the plane of a refractory material. The method comprises the following steps: moving a tool to the upper surface of the refractory material to be processed, maintaining a first preset gap between the tool and the upper surface, placing a feeler gauge of standard thickness in the first preset gap, and slowly moving the tool downward until the feeler gauge of standard thickness has resistance when sliding, completing tool alignment on the upper surface of the refractory material to be processed, and calculating a tool alignment error value for thickness, and compensating the tool alignment error value for thickness into a machine tool, thereby eliminating a manufacturing error of the thickness of the refractory material and a manufacturing error of the tool; adding a first adjustment amount to the tool alignment error value for thickness to obtain a first processing allowance, and compensating the first processing allowance into the machine tool, thereby avoiding overcutting on the upper surface due to tool wear when processing the circular arc, and making the circular arc and the upper surface smoothly connected; moving the tool to the side surface of the refractory material to be processed, maintaining a second preset gap between the tool and the side surface, and slowly moving the tool downward until the feeler gauge of standard thickness has resistance when sliding, thereby completing tool alignment on the upper surface of the refractory material to be processed, and calculating a tool alignment error value for thickness, and compensating the tool alignment error value for thickness into a machine tool, thereby eliminating a manufacturing error of the thickness of the refractory material and a manufacturing error of the tool; and increasing a first adjustment amount to obtain a first processing allowance, and compensating the first processing allowance into the machine tool, thereby avoiding overcutting on the upper surface due to tool wear when processing the circular arc, and making the circular arc and the upper surface smoothly connected; and moving the tool to the side surface of the refractory material to be processed, maintaining a second preset gap between the tool and the side surface, and slowly moving the tool downward until the feeler gauge of standard thickness has resistance, and finally completing tool alignment on the upper surface of the refractory material to be processed, and finally calculating a tool alignment error value for thickness, and finally compensating the tool alignment error value for thickness, thereby eliminating a manufacturing error of the thickness of the Preset the gap, put the standard thickness feeler gauge into the second preset gap, slowly move the tool to the side until the standard thickness feeler gauge has resistance when sliding, complete the side tool alignment of the refractory material to be processed and calculate the width tool alignment error value, and compensate the width tool alignment error value to the machine tool, which can eliminate the manufacturing error of the refractory material width and the manufacturing error of the tool diameter; add the second adjustment amount to the width tool alignment error value to obtain the second machining allowance, and compensate the second machining allowance to the machine tool, start the machine tool and move the tool close to the side with a preset step distance until scratches appear on the side and then stop feeding, restart the machine tool to process the arc of the refractory material to be processed, and after the processing is completed, the arc of the refractory material to be processed smoothly connects the upper surface and the side, which can avoid overcutting on the side of the refractory material to be processed when processing the arc, and make the arc and the side smoothly connected.

Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0021] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] In the substrate glass project construction industry, it is necessary to process various refractory materials of different specifications. Due to the high requirements for equipment precision, no edges or corners are allowed, especially at the intersection of the installation plane and the arc. The plane and the arc surface are required to be smoothly connected. In the actual processing process, depressions and edges and corners often appear here, resulting in the equipment precision not being achieved and not meeting the use requirements. Figure 1 and Figure 2 As shown, the refractory material generates an edge angle R-1 where the upper surface and the arc meet, and an edge angle R-2 where the side surface and the arc meet; Figure 3 As shown, a depression is produced on the upper surface 1 and the processed arc corner R, and a depression is produced on the side surface 2 and the processed arc corner R.

[0024] There is a manufacturing error in the thickness 9 of the refractory material 8 to be processed, and there is also a manufacturing error in the arc surface of the tool 6. Using the theoretical value to align the tool will cause a processing error. The method to eliminate the error value in the thickness direction is: measure the error between the actual value and the theoretical value of the material thickness, move the tool to the surface to be processed, and reserve a certain gap. Due to the manufacturing error of the tool, the tool 6 is an arc surface with diamond particles coated on the surface, and it is difficult to accurately measure the accuracy of the arc. If the tool is aligned according to the theoretical value, a processing error will occur, which will produce the following Figure 4 How to eliminate the overcutting phenomenon shown in detail B in the tool manufacturing error to avoid Figure 4 The overcutting phenomenon shown in detail B is the problem to be solved in this embodiment. The width 10 of the refractory material 8 to be processed also has a manufacturing error, and the diameter of the tool 6 also has a manufacturing error. If the tool is processed according to the theoretical value, the overcutting phenomenon will occur. Figure 5 The overcutting phenomenon shown in detail A will produce an edge angle of R-2 on the side of the processed arc angle R. Method for eliminating the side tool error: Move the tool 6 to the side of the refractory material 8 to be processed, leaving a certain gap.

[0025] Therefore, this embodiment provides a processing method to ensure smooth connection between the arc and the plane of the refractory material, comprising the following steps: S1: Figure 6 and Figure 7 As shown, the tool 6 is moved to the upper surface 1 of the refractory material 8 to be processed, a feeler gauge of standard thickness is placed in the first preset gap 5, and the tool 6 is slowly moved downward until the feeler gauge of standard thickness slides with a certain resistance, completing the tool setting of the upper surface of the refractory material 8 to be processed, and calculating the error between the theoretical value and the actual value to obtain the tool setting error value of the thickness 9, which is compensated in the machine tool to eliminate the manufacturing error of the thickness of the workpiece and the manufacturing error of the tool.

[0026] S2: After eliminating the manufacturing error of the workpiece and the manufacturing error of the tool, the thickness direction is increased by 0.02mm-0.05mm on the basis of the tool error value, so as to avoid the occurrence of damage to the upper surface 1 of the refractory material 8 to be processed due to tool wear when processing the arc. Figure 4 Overcutting is shown in detail B.

[0027] S3: Figure 8 As shown in detail D, a feeler gauge of standard thickness is placed in the second preset gap 4, and the tool 6 is slowly moved toward the side 2 until the feeler gauge of standard thickness slides with a certain resistance. The side tool alignment of the refractory material 8 to be processed is completed, and the error between the theoretical value and the actual value is calculated to obtain the tool alignment error value of the width 10. The tool alignment error value is compensated in the machine tool to eliminate the manufacturing error of the workpiece width 10 and the manufacturing error of the tool diameter 12.

[0028] S4: After eliminating the manufacturing error of the workpiece width 10 and the tool diameter 12, the width 10 is increased by 0.05mm-0.1mm on the basis of its tool setting error value, so that the first cut during processing cannot reach the side, and the error value can be reduced by 0.02 steps in the machine tool for each cut until a slight scratch appears on the side of the refractory material 8 to be processed, then the error value reduction is stopped and processing is restarted, thus avoiding the occurrence of scratches on the side 2 of the refractory material 8 to be processed when processing the arc. Figure 5 Overcutting is shown in detail A.

[0029] Specifically, before processing the arc, the error value of the thickness 9 and the error value of the width 10 of the refractory material 8 to be processed need to be measured in advance, such as Figure 6 As shown, 3 is the allowance that needs to be processed.

[0030] Specifically, the first preset gap 5 is greater than 0.2mm and less than 0.3mm, and the thickness of the standard thickness feeler gauge is 0.1mm; in order to ensure a smooth connection between the arc of the refractory material 8 to be processed and the upper surface 1, 0.02-0.05mm is added to the tool error value of the thickness 9, so that the processed arc will have no edges and corners at R-1, ensuring a smooth transition.

[0031] Specifically, the second preset gap 4 is greater than 0.2 mm and less than 0.3 mm. In order to ensure smooth connection of the side, 0.05-0.1 mm is added to the tool error value of the width 10, and the tool approaches the side with a step distance of 0.02 mm until a slight scratch appears on the side 2 of the workpiece 8, stops feeding, and restarts the machine tool to process the arc, thus ensuring smooth connection between the side 2 and the arc R, avoiding the edges and corners at R-2.

[0032] Specifically, the distance between the tangent line of the tool arc 11 of the tool 6 and the upper surface 1 is the first preset gap 5 .

[0033] Specifically, the distance between the side surface 7 of the tool and the side surface 2 of the refractory material 8 to be processed is the second preset gap 4 .

[0034] The processing method provided in this embodiment ensures the smooth connection between the arc and the plane of the refractory material. In the process of processing the refractory material, there are workpiece size errors, clamping errors, tool setting errors, tool manufacturing errors, and machine tool processing errors, which cause the intersection of the arc and the plane to not be smoothly connected, resulting in overcutting or under-processing. This method changes the tool setting method to eliminate the processing errors, tool manufacturing errors, workpiece clamping errors, and tool setting errors in the workpiece material itself to process the arc surface of the workpiece. This method solves the processing defects of the existing arc in the processing process, allows the intersection of the arc and the plane to be smoothly connected, and avoids problems caused by the arc not meeting the design requirements during assembly.

[0035] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects, not exclusive, and all changes within the scope of the present invention or equivalent to the scope of the present invention are included in the present invention.
