Description

Technical Field

[0001] The present invention relates to the field of grinding technology, and in particular to an integrated grinding and detection device for die steel and a use method thereof. Background Art

[0002] Grinding is a finishing process (such as cutting) of the machined surface by means of abrasive particles coated or pressed on the grinding tool, through the relative movement of the grinding tool and the workpiece under a certain pressure. Grinding can be used to process various metal and non-metal materials. The machined surface shapes include planes, internal and external cylindrical and conical surfaces, convex and concave spherical surfaces, threads, tooth surfaces and other surfaces.

[0003] Flatness refers to the degree of difference between the surface of an object and the absolute flatness or horizontal state during the processing or production process. Specifically, flatness refers to the local flatness of the surface of an object within a specific range. It is usually expressed as a numerical value. The smaller the value, the better the flatness. In the manufacturing industry, flatness affects the appearance and quality of the product, especially in industries that require high-precision processing such as machinery manufacturing, automobile manufacturing, etc.

[0004] Mold steel is a type of steel used to manufacture molds such as cold stamping dies, hot forging dies, and die-casting molds. Mold materials are the material and technical basis of the mold manufacturing industry. Among them, mold steel is a traditional mold material. Its variety, specification, and quality play a decisive role in the performance, service life, and manufacturing cycle of the mold. Molds have a wide range of uses, and a wide range of materials are used to manufacture molds. The most widely used mold material is mold steel. At present, many mold steels need to be ground and finished using grinding equipment during the processing into molds.

[0005] The existing grinding equipment can only grind the mold steel but cannot perform flatness detection. The mold steel also needs to be tested for flatness after grinding to ensure that the accuracy meets the requirements. This requires that the mold steel be disassembled and transferred to the detection equipment for flatness detection after grinding. This will cause a single workpiece to be disassembled and transferred twice before grinding and detection can be completed, which is inconvenient and affects the production speed. For this reason, we propose an integrated grinding and detection device for mold steel and a method of using it to solve the above problems. Summary of the invention

A plurality of locking bolts 33 on the side of the adjusting seat 31 are loosened, and then the adjusting seat 31 is fixed. Keep away from the fixed clamping plate 30, then place the mold steel on the support table 29, then adjust the adjustment seat 31 to a suitable position, and then tighten the locking bolt 33 beside the adjustment seat 31 to fix the adjustment seat 31. A second threaded hole and a plurality of guide holes are provided on one side of the adjustment seat 31. An adjusting bolt 34 is provided on the inner side of the second threaded hole through a threaded connection. An active clamping plate 35 is rotatably provided on the axial end of the adjusting bolt 34. A plurality of guide rods 36 are fixed on one side of the active clamping plate 35. The guide rods 36 slide on the inner side of the guide hole to fix the fixed clamping plate 30. After adjusting the seat 31, it is necessary to rotate the adjusting bolt 34 so that the active clamping plate 35 is close to the mold steel, and tighten the adjusting bolt 34 so that the mold steel is clamped between the active clamping plate 35 and the fixed clamping plate 30. At this time, the fixation is completed. A locking nut is provided on the outer periphery of the adjusting bolt 34 through a threaded connection.

[0044] like Figure 1 , Figure 2 , Figure 4 , Figures 7 to 9 , Fig.12 , Fig.13As shown, a reciprocating grinding assembly is provided on the upper side of the base 1, the reciprocating grinding assembly is used for grinding the workpiece, the displacement assembly is used for driving the reciprocating grinding assembly to translate, the reciprocating grinding assembly includes a floating frame 3 and a grinding head 6, the floating frame 3 is a U-shaped structure, a reciprocating frame 4 is slidably provided on the inner side of the floating frame 3, the reciprocating frame 4 is a T-shaped structure, a reciprocating driving assembly is provided on one side of the reciprocating frame 4, the reciprocating driving assembly includes a lifting slider 10, the lifting slider 10 slides on one side of the reciprocating frame 4, the lifting slider 10 is a U-shaped structure, and two contact wheels 11 are rotatably provided on the inner side of the lifting slider 10, the two contact wheels 11 have the same size specifications, and the two contact wheels 11 are in the same Horizontal height, a lifting hole 12 is provided on the other side of the reciprocating frame 4, and the contact wheel 11 contacts the inner wall of the lifting hole 12. A connecting shaft 13 is rotatably provided on one side of the lifting slider 10, and a rotating rod 14 is rotatably provided on the outer periphery of the connecting shaft 13. A supporting frame 15 is fixedly provided on one side of the floating frame 3, and a reciprocating stepper motor 16 is fixedly provided on one side of the supporting frame 15. The reciprocating stepper motor 16 is connected to an external driving controller and a power supply through a wire, and the rotating rod 14 is fixed on the shaft end of the reciprocating stepper motor 16. After fixing the mold steel, when the mold steel needs to be ground, the reciprocating stepper motor 16 needs to be turned on, and the reciprocating stepper motor 16 will drive the rotating rod 14 to do circular motion. The rotating rod 14 will drive the connecting shaft 13, the contact wheel 11 and the lifting slider 10 to make a circular motion together. When the contact wheel 11 makes a circular motion, it will move up and down on the inner side of the lifting hole 12, so as to drive the reciprocating frame 4 to make a reciprocating motion on the inner side of the floating frame 3. When the reciprocating frame 4 makes a reciprocating motion, it will drive the grinding head 6 to move together. During the reciprocating motion, the grinding head 6 can grind the upper surface of the mold steel, so that automatic grinding can be performed. An angle adjustment component is provided between the grinding head 6 and the reciprocating frame 4. The angle adjustment component includes a rotating shaft 5. A shaft hole is provided on one side of the reciprocating frame 4. The rotating shaft 5 rotates on the inner side of the shaft hole. One side of the rotating shaft 5 A rotating stepper motor 7 is fixed at one end, and the rotating stepper motor 7 is fixed on the reciprocating frame 4. The rotating stepper motor 7 is connected to an external driving controller and a power supply through a wire. A rotating frame 8 is fixed at the other end of the rotating shaft 5. A plurality of mounting seats 9 are fixed on the outer periphery of the rotating frame 8. A grinding head 6 is fixed on a mounting seat 9. When it is necessary to grind the inclined surface of the mold steel, the rotating stepper motor 7 can be controlled to rotate a certain number of circles to drive the rotating shaft 5, the rotating frame 8, the mounting seat 9 and the grinding head 6 to rotate, so that the grinding head 6 can be adjusted to a tilted state, and then the inclined surface can be ground. It has a tilted grinding function and can be suitable for a variety of mold steels.

[0045] like Figure 7 , Fig. 9As shown, a displacement assembly is provided on the upper side of the base 1, and the displacement assembly includes a horizontal threaded rod 17. Through holes are provided on the two sides of the hood 2 that are away from each other. The horizontal threaded rod 17 rotates on the inner side of the through hole. A movable frame 18 is provided on the outer periphery of the horizontal threaded rod 17 through a threaded connection. The movable frame 18 slides on the upper side of the base 1, and the floating frame 3 slides on the inner side of the movable frame 18. A translation stepper motor 19 is fixed on the outer wall of the hood 2. The translation stepper motor 19 is connected to an external drive controller and a power supply through a wire. The shaft end of the translation stepper motor 19 is connected to the horizontal threaded rod 1 The outer peripheries of 7 are connected by bevel gear transmission. During the grinding of the mold steel, it is necessary to make the movable frame 18 translate to drive the floating frame 3 and the grinding head 6 to move, so that the grinding head 6 can be ground to different positions. When the movable frame 18 needs to translate, it is necessary to control the translation stepper motor 19 to rotate. When the translation stepper motor 19 rotates, it can drive the horizontal threaded rod 17 to rotate through the bevel gear. When the horizontal threaded rod 17 rotates, the movable frame 18 can be translated, thereby realizing continuous grinding and grinding different positions.

[0046] like Figure 4 , Figure 5 , Figures 9 to 12As shown, a height-fixing assembly is provided between the displacement assembly and the reciprocating grinding assembly, and the height-fixing assembly is used to determine the grinding height. The height-fixing assembly includes a vertical threaded rod 20, the lower end of the vertical threaded rod 20 rotates on the upper side of the bottom of the moving frame 18, and a lifting stepping motor 21 is fixedly provided on the upper end of the vertical threaded rod 20. A fixed seat 22 is rotatably provided on the outer periphery of the vertical threaded rod 20, and the fixed seat 22 and the lifting stepping motor 21 are fixed on the inner side of the moving frame 18. The lifting stepping motor 21 is connected to an external driving controller and a power supply through a wire. A lifting block 23 is provided on the outer periphery of 20 through a threaded connection. The lifting block 23 slides on the inner side of the mobile frame 18. A fixed height frame 24 is fixed on one side of the floating frame 3. The floating frame 3 is located between the fixed height frame 24 and the support frame 15. The upper side of the lifting block 23 can contact the fixed height frame 24. During use, it is necessary to control the lifting stepper motor 21 to rotate to drive the vertical threaded rod 20 to rotate. When the vertical threaded rod 20 rotates, the lifting block 23 can be lowered or raised, and the lifting block 23 can block the fixed height frame 24. When the fixed height frame 24 is blocked by the lifting block 23, it cannot be lowered. In this way, during the grinding of the mold steel, the lowest position of the grinding head 6 can be ensured, thereby preventing excessive grinding. Moreover, during the replacement of the mold steel, before grinding, and after grinding, the lifting block 23 can be driven to rise and lift the fixed height frame 24 and the grinding head 6 by controlling the rotation of the lifting stepper motor 21, so as to facilitate the replacement of the mold steel and enable the grinding head 6 to fall stably on the upper surface of the mold steel. A tension spring 37 is fixed between the lower side of the floating frame 3 and the upper side of the bottom of the moving frame 18. During the grinding of the mold steel, the tension of the tension spring 37 will make the grinding head 6 close to the upper surface of the mold steel. At this time, by controlling the translation stepper motor 19 and the reciprocating stepper motor 16 to move the grinding head 6, safe grinding can be performed. The downward pressure on the grinding head 6 is relatively elastic, and the state of the grinding head 6 during grinding is a non-rigid connection state, so the grinding head 6 will not damage or scratch the mold steel, which has high safety.

[0047] like Figure 5 , Fig.10 , Fig.12As shown, a detection component is provided on one side of the height setting component, and the detection component includes a mounting plate 25. A mounting groove is provided on one side of the lifting block 23. The mounting plate 25 is fixed on the inner side of the mounting groove. A mounting hole is provided on the upper side of the mounting plate 25. A distance sensor 26 is fixed on the inner side of the mounting hole. The distance sensor 26 is connected to an external processor and a power supply through a wire. A reflection measuring piece 27 is provided above the distance sensor 26. The reflection measuring piece 27 is fixed on the height setting frame 24. During the grinding of the mold steel, the distance sensor 26 can be used to measure the distance between the distance sensor 26 and the reflection measuring piece 27. The distance between the lifting block 23 and the fixed height frame 24 can be known by the distance between the distance measuring sensor 26 and the reflection measuring piece 27, and the height of the lifting block 23 is controlled by the lifting stepping motor 21, and the fixed height frame 24 and the grinding head 6 are in a relatively static state, so the height of the grinding head 6 can be known by the distance between the distance measuring sensor 26 and the reflection measuring piece 27. The grinding situation can be known by knowing the height of the grinding head 6, thereby preventing the situation of over-deep grinding and inadequate grinding, and having higher grinding accuracy.

[0048] like Figure 2 , Figure 8As shown, a contact component is provided on one side of the detection component, and the contact component is used to contact with the surface of the workpiece, and the height-fixing component is used to drive the contact component to be close to the surface of the workpiece. The detection component is used to detect the height of the contact component, and the height-fixing component is used to adjust the height of the detection component. The height-fixing component can make the reciprocating grinding component in an elastic connection state, specifically: the height-fixing component first makes the detection component drop a suitable distance, at which time the contact component can be close to the surface of the workpiece, and then the flatness detection can be carried out by cooperating with the detection component, the displacement component and the reciprocating grinding component. The contact component includes a plurality of pointed contact heads 28, and the shapes and specifications of the pointed contact heads 28 are different, specifically including: a pointed cone-type contact head, a pointed plate-type contact head, and a double-pointed plate-type contact head. The pointed contact heads 28 are respectively fixed on the mounting seat 9. When it is necessary to perform a flatness detection on the upper surface of the mold steel, it is necessary to first control the lifting stepper motor 21 to rotate so that the lifting block 23 and the grinding head 6 are raised, and then control the rotating stepper motor 7 to rotate a certain number of times so that a suitable pointed contact head 28 is located at the rotating shaft 5. The lifting block 23 is moved to the lower position, and then the lifting stepper motor 21 is controlled to rotate so that the lifting block 23 is lowered to a suitable height. At this time, a pointed contact head 28 will contact the upper surface of the mold steel. At this time, it is necessary to make a certain distance between the distance sensor 26 and the reflection measurement piece 27 (that is, the lifting block 23 will not block the fixed height frame 24). Then, the pointed contact head 28 is moved by controlling the translation stepper motor 19 to rotate, or the pointed contact head 28 is moved by controlling the reciprocating stepper motor 16 to rotate. During the movement of the pointed contact head 28, the tension of the tension spring 37 will make the pointed contact head 28 close to the upper surface of the mold steel, so the pointed contact head 28 and the reflection measurement piece 27 will change in height following the ups and downs of the upper surface of the mold steel. During the movement of the pointed contact head 28, the distance sensor 26 monitors the distance between the distance sensor 26 and the reflection measurement piece 27 in real time, so that the height change of the pointed contact head 28 during this period can be known, thereby the flatness of the upper surface of the mold steel can be known, and the function of automatically detecting the flatness can be obtained.

[0049] In summary, a method for using a grinding and detection integrated device for mold steel comprises the following steps:

[0050] S1. Clamp and fix the workpiece by a clamping assembly;

[0051] S2. When the workpiece needs to be ground, the upper surface of the workpiece is ground by cooperating with the reciprocating grinding assembly, the displacement assembly, and the height setting assembly;
