Description

Technical Field

[0001] This invention relates to the field of grinding wheel equipment, and in particular to a new type of grinding device and grinding method for producing diamond composite grinding wheels. Background Technology

[0002] Grinding wheels are the most commonly used components in grinding operations. Grinding wheels require dressing, and grinding wheel dressers are auxiliary tools used to dress the size, shape, and geometry of grinding wheels on grinding machines. Dressing machines are used to shape and mill the contours of grinding wheels used on machine tools. In addition to the surface, one or two sides of the grinding wheel often need to be ground and dressed to obtain the required contour. When processing grinding wheel blanks with different grinding requirements, different grinding tools often need to be changed, which is inconvenient. Furthermore, the thickness and coverage of grinding surfaces vary between different types of grinding wheels, resulting in a large number of grinding tools required during processing. This not only increases costs but also requires a large amount of space for preparation tools, and the need for frequent tool changes makes the processing cumbersome. Therefore, we propose a novel grinding device and grinding method for the production of diamond composite grinding wheels to solve the aforementioned problems. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art by proposing a novel grinding device and grinding method for the production of diamond composite grinding wheels.

A bevel gear is fixedly connected to one end of the outer circumference of the threaded rod. The front part of the bevel gear is meshed with the rear part of the bevel gear ring. A limit ring is rotatably connected to the inner side of the bevel gear ring. A uniformly distributed connecting block is fixedly connected to the rear part of the limit ring. The connecting block is fixedly connected to the end of the fixing plate. The fixing plate is fixedly connected to the side of the mounting block that is close to it.

[0005] Preferably, the second side grinding assembly includes an inner slip ring, which is slidably connected to the inner side of the slip ring sleeve. A uniformly distributed second mounting block is fixedly connected to the side of the inner slip ring near the grinding wheel. The second mounting blocks are staggered with the first mounting block. A second grinding disc is slidably connected to the end of each second mounting block away from the inner slip ring. A threaded rod is threadedly connected to one side of each second grinding disc. A bevel gear is fixedly connected to one side of the outer circumference of each second threaded rod. The front of each bevel gear is meshed with the rear of a bevel ring. A limit ring is rotatably connected to the inner side of the bevel ring. A uniformly distributed second connecting block is fixedly connected to the rear of the limit ring. The second connecting block is fixedly connected to the end of a second fixing plate. The second fixing plate is fixedly connected to the side of the second mounting block that is close to it.

[0006] Preferably, each of the first and second threaded rods is fixedly connected to a stepper motor, and the stepper motors are respectively mounted on the end faces of the first and second connecting blocks.

[0007] Preferably, each of the inner slip rings has an internal threaded groove at the end away from the mounting block 2, and an external threaded ring is threadedly connected to the inner side of each internal threaded groove. An internal gear ring is fixedly connected to the end of each external threaded ring near the grinding wheel, and a transmission gear is meshed with the inner side of each internal gear ring.

[0008] Preferably, the inner slip ring has uniformly distributed limiting grooves on its outer circumference, and each limiting groove is slidably connected to a limiting strip, which is disposed on the inner side of the slip ring sleeve.

[0009] Preferably, both the second and the first grinding discs penetrate one end face of the side frame and are close to each other. Both ends of the grinding wheel are provided with evenly distributed guide grooves, which correspond to the second and the first grinding discs.

[0010] Preferably, a spindle housing is installed on one side of the front top of the machine body, and a grinding wheel blank is installed on the outer periphery of the drive shaft on one side of the spindle housing.

[0011] Preferably, one side of the side frame is fixedly connected to a connecting flange, and the side frame is connected to the servo motor drive end through the connecting flange. The servo motor is installed in the middle of one side of the housing.

[0012] Preferably, the transmission gears on the side away from the inner gear ring are all meshed with the outer circumference of the outer gear ring, the outer gear rings are all fixedly connected to the outer circumference of the hub motor, and the hub motors are all installed in the middle of the side frame.

[0013] Preferably, a grinding method for producing a novel diamond composite grinding wheel includes the following steps:

[0014] S1. During grinding, the grinding wheel blank is first installed on the spindle of the spindle housing, and then the grinding assembly is installed inside the housing. Then, the grinding assembly is rotated by the servo motor. Then, the grinding assembly is moved laterally by the first electric slide and moved longitudinally by the second electric slide. The grinding assembly is moved closer to the grinding wheel blank by the first and second electric slides.

[0015] S2. Start the spindle housing and servo motor. The spindle housing drives the grinding wheel blank to rotate, and the servo motor drives the grinding assembly to rotate. The grinding assembly grinds the grinding wheel blank. During grinding, the speed ratio between the grinding assembly and the grinding wheel blank is 3:1.

[0016] S3. During grinding, the grinding wheel is brought close to the grinding wheel blank by the electric slide table. The outer circumferential rotating surface of the grinding wheel blank is ground by the relative rotation between the grinding wheel and the grinding wheel blank.

[0017] S4. After the grinding wheel blank is ground, the front and rear end faces of the grinding wheel blank are ground by the side grinding assembly in the side frame. During grinding, the side frame is first brought close to the grinding wheel blank by the electric slide table to grind one end face of the grinding wheel blank. Then the grinding assembly is moved by the electric slide table to bring the other side frame close to the grinding wheel blank to grind the other end face of the grinding wheel blank.

[0018] S5. During grinding, start the hub motor, which drives the external gear ring to rotate. The external gear ring drives the transmission gear to rotate, and the transmission gear drives the internal gear ring to rotate the external threaded ring. When the external threaded ring rotates, it drives the internal sliding ring to move along the limiting strip and the limiting groove, thereby driving the second side grinding group to be ejected, thus switching the side grinding assembly in contact with the grinding wheel blank. By switching between the first side grinding group and the second side grinding group, continuous rough grinding and fine grinding of the end face of the grinding wheel blank are performed.

[0019] S6. During the grinding of grinding wheel blanks with different grinding diameters, the stepper motors in the first and second side grinding groups are started. The stepper motors drive bevel gear 2 or bevel gear 1 to rotate. Bevel gear 2 and bevel gear 1 drive threaded rod 2 and threaded rod 1 to rotate respectively. Threaded rod 2 and threaded rod 1 drive grinding disc 2 and grinding disc 1 to move respectively, thereby controlling the extension length of grinding disc 1 and grinding disc 2 before grinding.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. During grinding, the hub motor can be started, which drives the external gear ring to rotate. The external gear ring drives the transmission gear to rotate, which in turn drives the internal gear ring to rotate the external threaded ring. When the external threaded ring rotates, it drives the internal sliding ring to move along the limiting strip and limiting groove, thereby driving the second side grinding set to be ejected. This allows switching of the side grinding assembly in contact with the grinding wheel blank. By switching between the first and second side grinding sets, continuous rough grinding and fine grinding of the end face of the grinding wheel blank can be achieved, which is beneficial for the dressing work of the grinding wheel blank. At the same time, the first and second side grinding sets can achieve single grinding of grinding wheel blanks with different grinding requirements, which is beneficial for adapting to the processing of grinding wheel blanks with different grinding requirements.

[0022] 2. During grinding, the grinding wheel is first brought close to the grinding wheel blank by the electric slide two. The relative rotation between the grinding wheel and the grinding wheel blank enables the grinding of the outer circumferential rotating surface of the grinding wheel blank. After the grinding wheel blank is ground, the side grinding assembly in the side frame enables the grinding of the front and rear end faces of the grinding wheel blank. During grinding, the electric slide one first brings one side frame close to the grinding wheel blank to grind one end face of the grinding wheel blank. Then, the electric slide one moves the grinding assembly so that the other side frame is brought close to the grinding wheel blank to grind the other end face of the grinding wheel blank. Thus, the grinding wheel blank can be completely ground by one grinding assembly, thereby avoiding the need to change grinding tools during the grinding process.

[0023] 3. During the grinding process, the stepper motors in the first and second side grinding groups can be started. The stepper motors can drive bevel gear 2 or bevel gear 1 to rotate. Bevel gear 2 and bevel gear 1 can drive threaded rod 2 and threaded rod 1 to rotate respectively. Threaded rod 2 and threaded rod 1 can drive grinding disc 2 and grinding disc 1 to move respectively. This allows the extension length of grinding disc 1 and grinding disc 2 to be controlled before grinding, so that grinding components can use grinding wheel blanks with different grinding diameters, which is beneficial for practical use.

[0024] 4. Because the grinding area of ​​the grinding wheel is relatively wide, during continuous grinding, the electric slide can be controlled to move the grinding components, avoiding continuous repetition of the grinding area, which would cause excessive wear on the outer circumference of the grinding wheel and affect its service life. Switching the actual grinding point can help improve the overall life of the grinding wheel, and at the same time, it can adapt to the processing of the outer cylindrical surface of grinding wheel blanks of different thicknesses, which is beneficial for grinding grinding wheels of different specifications.

[0035] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0036] like Figures 1-9 The invention relates to a new type of grinding apparatus for producing diamond composite grinding wheels, comprising a grinding and dressing machine 1. The grinding and dressing machine 1 includes a body 101. An electric slide table 102 is mounted on the rear top of the body 101. An electric slide table 103 is located on one side of the middle of the electric slide table 102. A housing 105 is mounted on the top of the electric slide table 103. A grinding assembly is mounted on the front inner side of the housing 105. The grinding assembly includes a grinding wheel 108. Side supports 111 are mounted on both sides of the grinding wheel 108. A spindle housing 107 is mounted on one side of the front top of the body 101. A grinding wheel blank 106 is mounted on the outer periphery of a drive shaft on one side of the spindle housing 107. A connecting flange 1 is fixedly connected to one side support 111. 13. The side frame 111 is connected to the drive end of the servo motor 104 through the connecting flange 113. The servo motor 104 is installed in the middle of one side of the housing 105. The side frame 111 is equipped with a first side grinding group and a second side grinding group. The inner slip ring 118 is provided with uniformly distributed limiting grooves 131 on its outer periphery. The limiting grooves 131 are slidably connected with limiting strips 110. The limiting strips 110 are all set inside the slip ring sleeve 120. The second grinding disc 115 and the first grinding disc 109 pass through the side end face of the side frame 111 that are close to each other. The grinding wheel 108 is provided with uniformly distributed guide grooves 112 at both ends. The guide grooves 112 correspond to the second grinding disc 115 and the first grinding disc 109.

[0037] Furthermore, in specific implementation and actual use, the grinding and dressing machine 1 can be used to grind and dress the grinding wheel blank 106, so that the grinding wheel blank 106 can meet the standard for operation. During grinding, the grinding wheel blank 106 is first installed on the spindle of the spindle housing 107, and then the grinding assembly is installed inside the housing 105. Then, the servo motor 104 drives the grinding assembly to rotate, and then the electric slide table 102 drives the grinding assembly to move laterally, and the electric slide table 103 drives the grinding assembly to move longitudinally. The electric slide 103 can drive the grinding assembly to approach the grinding wheel blank 106. Then, the spindle housing 107 can drive the grinding wheel blank 106 to rotate. The servo motor 104 can drive the grinding assembly to rotate. The grinding assembly can grind the grinding wheel blank 106. During grinding, the speed ratio between the grinding assembly and the grinding wheel blank 106 is 3:1. In the grinding process, the electric slide 103 first brings the grinding wheel 108 close to the grinding wheel blank 106. The relative rotation between the grinding wheel 108 and the grinding wheel blank 106 can grind the outer circumferential rotating surface of the grinding wheel blank 106.

[0038] The first side grinding assembly includes a slip ring sleeve 120. Evenly distributed mounting blocks 117 are installed on the side of the slip ring sleeve 120 near the grinding wheel 108. Grinding discs 109 are slidably connected to the ends of the mounting blocks 117 away from the slip ring sleeve 120. Threaded rods 137 are threadedly connected to one side of each grinding disc 109. Bevel gears 135 are fixedly connected to one end of the outer circumference of each threaded rod 137. The front of each bevel gear 135 is meshed with the rear of the bevel ring 119. The inner side of the bevel ring 119 is rotatably connected to a limiting ring 134. A uniformly distributed connecting block 130 is fixedly connected to the rear of the limiting ring 134. Each connecting block 130 is fixedly connected to the end of a fixing plate 128. Each fixing plate 128 is fixedly connected to the side of the mounting block 117. The second side grinding assembly includes an inner slip ring 118, which is slidably connected to the inner side of the slip ring sleeve 120. The side of the inner slip ring 118 closest to the grinding wheel 108 is fixedly connected to the inner side of the grinding wheel 108. The mounting blocks 116 are evenly distributed and staggered with the mounting blocks 117. A grinding disc 115 is slidably connected to the end of each mounting block 116 away from the inner slip ring 118. A threaded rod 136 is threadedly connected to one side of each grinding disc 115. A bevel gear 125 is fixedly connected to one side of the outer circumference of each threaded rod 136. The front part of each bevel gear 125 is meshed with the rear part of a bevel ring 127. The inner side of the bevel ring 127... A rotatable connection is provided with a second limiting ring 133. A uniformly distributed second connecting block 138 is fixedly connected to the rear of the second limiting ring 133. The second connecting block 138 is fixedly connected to the end of the second fixing plate 126. The second fixing plate 126 is fixedly connected to the side of the second mounting block 116. A first threaded rod 137 and the end of the second threaded rod 136 are both fixedly connected with a stepper motor 132. The stepper motor 132 is respectively installed on the end face of the first connecting block 130 and the second connecting block 138.

[0039] Furthermore, in specific implementation, after the grinding wheel blank 106 is ground, the side grinding assembly within the side frame 111 can grind the front and rear end faces of the grinding wheel blank 106. During grinding, one side frame 111 is first moved close to the grinding wheel blank 106 via the electric slide 102 to grind one end face of the grinding wheel blank 106. Then, the grinding assembly is moved by the electric slide 102 to bring the other side frame 111 close to the grinding wheel blank 106 to grind the other end face of the grinding wheel blank 106. Thus, the grinding wheel blank 106 can be completely ground with a single grinding assembly, avoiding the need to change grinding tools during the grinding process, which is beneficial. In practical use, during the grinding process, the stepper motors 132 in the first and second side grinding groups can be activated. The stepper motors 132 can drive the second bevel gear 125 or the first bevel gear 135 to rotate. The second bevel gear 125 and the first bevel gear 135 can drive the second threaded rod 136 and the first threaded rod 137 to rotate, respectively. The second threaded rod 136 and the first threaded rod 137 can drive the second grinding disc 115 and the first grinding disc 109 to move, respectively. This allows the extension length of the first grinding disc 109 and the second grinding disc 115 to be controlled before grinding, so that the grinding assembly can use grinding wheel blanks 106 with different grinding diameters, which is beneficial to practical use.

[0040] Among them, the inner slip ring 118 is provided with an internal thread groove 129 at the end away from the mounting block 116. The inner side of the internal thread groove 129 is threaded with an external thread ring 121. The end of the external thread ring 121 near the grinding wheel 108 is fixedly connected with an internal gear ring 123. The inner side of the internal gear ring 123 is meshed with a transmission gear 122. The side of the transmission gear 122 away from the internal gear ring 123 is meshed with the outer circumference of the external gear ring 124. The external gear ring 124 is fixedly connected to the outer circumference of the hub motor 114. The hub motor 114 is installed in the middle of the side frame 111.

[0041] Furthermore, in specific implementation, during grinding, the hub motor 114 can be started, which drives the external gear ring 124 to rotate. The external gear ring 124 drives the transmission gear 122 to rotate, which in turn drives the internal gear ring 123 to rotate the external threaded ring 121. When the external threaded ring 121 rotates, it drives the internal sliding ring 118 to move along the limiting strip 110 and the limiting groove 131, thereby driving the second side grinding group to be ejected. This allows switching of the side grinding components in contact with the grinding wheel blank 106. By switching between the first and second side grinding groups, continuous rough and fine grinding of the end face of the grinding wheel blank 106 can be achieved, which is beneficial for the dressing work of the grinding wheel blank 106. At the same time, the first and second side grinding groups can achieve single grinding of the grinding wheel blank 106 with different grinding requirements, which is beneficial for adapting to the processing of grinding wheel blanks 106 with different grinding requirements.

[0042] One of the grinding methods for producing a novel diamond composite grinding wheel includes the following steps:

[0043] S1. During grinding, the grinding wheel blank 106 is first installed on the spindle of the spindle housing 107, and then the grinding assembly is installed inside the housing 105. Then, the grinding assembly is rotated by the servo motor 104, and then the grinding assembly is moved laterally by the electric slide table 102 and moved longitudinally by the electric slide table 2. The grinding assembly is moved closer to the grinding wheel blank 106 by the electric slide table 102 and the electric slide table 2 103.

[0044] S2. Start the spindle housing 107 and servo motor 104. The spindle housing 107 drives the grinding wheel blank 106 to rotate, and the servo motor 104 drives the grinding assembly to rotate. The grinding assembly grinds the grinding wheel blank 106. During grinding, the speed ratio between the grinding assembly and the grinding wheel blank 106 is 3:1.

[0045] S3. During grinding, the grinding wheel 108 is brought close to the grinding wheel blank 106 by the electric slide table 103. The outer circumferential rotating surface of the grinding wheel blank 106 is ground by the relative rotation between the grinding wheel 108 and the grinding wheel blank 106.

[0046] S4. After the grinding wheel blank 106 is ground, the front and rear end faces of the grinding wheel blank 106 are ground by the side grinding assembly in the side frame 111. During grinding, the side frame 111 is first brought close to the grinding wheel blank 106 by the electric slide table 102, and the end face of the grinding wheel blank 106 is ground first. Then, the grinding assembly is moved by the electric slide table 102 so that the side frame 111 on the other side is brought close to the grinding wheel blank 106, and the end face of the other side of the grinding wheel blank 106 is ground.

[0047] S5. During grinding, the hub motor 114 is started, which drives the external gear ring 124 to rotate. The external gear ring 124 drives the transmission gear 122 to rotate. The transmission gear 122 drives the internal gear ring 123 to rotate the external threaded ring 121. When the external threaded ring 121 rotates, it drives the internal sliding ring 118 to move along the limiting strip 110 and the limiting groove 131, thereby driving the second side grinding group to be ejected, thereby switching the side grinding assembly in contact with the grinding wheel blank 106. By switching between the first side grinding group and the second side grinding group, continuous rough grinding and fine grinding of the end face of the grinding wheel blank 106 are performed.

[0048] S6. During the grinding of grinding wheel blanks 106 with different grinding diameters, the stepper motors 132 in the first and second side grinding groups are started. The stepper motors 132 drive the bevel gear 125 or bevel gear 135 to rotate. The bevel gear 125 and bevel gear 135 drive the threaded rod 136 and threaded rod 137 to rotate respectively. The threaded rod 136 and threaded rod 137 drive the grinding disc 115 and grinding disc 109 to move respectively, thereby controlling the extension length of grinding disc 109 and grinding disc 115 before grinding.

[0049] Working principle:

[0050] In practical use, the grinding and dressing machine 1 can be used to grind and dress the grinding wheel blank 106, so that the grinding wheel blank 106 meets the standard for operation. During grinding, the grinding wheel blank 106 is first installed on the spindle of the spindle housing 107, and then the grinding assembly is installed inside the housing 105. Then, the servo motor 104 drives the grinding assembly to rotate, and then the electric slide 102 drives the grinding assembly to move laterally, and the electric slide 2 103 drives the grinding assembly to move longitudinally. The electric slides 102 and 103 drive the grinding assembly to move closer to the grinding wheel blank 106, and then the spindle housing 107 drives the grinding wheel blank 106 to rotate. The servo motor 104 drives the grinding assembly to rotate, which in turn grinds the grinding wheel blank 106. During grinding, the speed ratio between the grinding assembly and the grinding wheel blank 106 is 3:1. In the grinding process, the electric slide 103 first moves the grinding wheel 108 close to the grinding wheel blank 106. The relative rotation between the grinding wheel 108 and the grinding wheel blank 106 grinds the outer circumferential rotating surface of the grinding wheel blank 106. After the grinding wheel blank 106 is ground, the side grinding assembly in the side frame 111 grinds the front and rear end faces of the grinding wheel blank 106. During grinding, the electric slide 102 first moves one side frame 111 close to the grinding wheel blank 106 to grind one end face of the grinding wheel blank 106. After grinding, the grinding assembly is moved by the electric slide table 102, so that the side frame 111 on the other side is close to the grinding wheel blank 106 to grind the end face of the grinding wheel blank 106. This allows the grinding wheel blank 106 to be completely ground with a single grinding assembly, thus avoiding the need to change grinding tools during the grinding process, which is beneficial for practical use. During grinding, the hub motor 114 can be started, which drives the external gear ring 124 to rotate. The external gear ring 124 drives the transmission gear 122 to rotate, which in turn drives the internal gear ring 123 to rotate the external threaded ring 121. When the external threaded ring 121 rotates, it drives the internal slip ring 118 to move along the limit. The positioning bar 110 moves with the limiting groove 131, thereby driving the second side grinding group to be ejected. This allows switching of the side grinding assembly in contact with the grinding wheel blank 106. By switching between the first and second side grinding groups, continuous rough and fine grinding of the end face of the grinding wheel blank 106 can be achieved, which is beneficial for dressing the grinding wheel blank 106. At the same time, the first and second side grinding groups can achieve single grinding of grinding wheel blanks 106 with different grinding requirements, which is beneficial for adapting to the processing of grinding wheel blanks 106 with different grinding requirements. Meanwhile, during the grinding process, the stepper motor 132 in the first and second side grinding groups can be started, which drives the second bevel gear 125 or the first bevel gear 135 to rotate.The bevel gears 125 and 135 drive the threaded rods 136 and 137 to rotate, respectively. These rods, in turn, move the grinding discs 115 and 109. This allows control over the extension length of the grinding discs 109 and 115 before grinding, enabling the grinding assembly to use grinding wheel blanks 106 with different grinding diameters. This is beneficial for practical use. Furthermore, the grinding area of ​​the grinding wheel 108 is relatively wide. During continuous grinding, the electric slide 102 can be controlled to move the grinding assembly, preventing repeated grinding and excessive wear on the outer circumference of the grinding wheel 108, which would affect its service life. Switching the actual grinding point can improve the overall lifespan of the grinding wheel 108 and allow it to process the outer surface of grinding wheel blanks 106 with different thicknesses, further enhancing its practical application.
