Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheels, in particular to a dressing device for ceramic superhard grinding wheels. Background Technique

[0002] A grinding wheel is a tool used for grinding, polishing and cutting metals or other materials. It consists of abrasive grains (such as alumina, silicon carbide, etc.) and a binder (such as resin, ceramic, etc.), and is usually in a disc shape. Grinding wheels are widely used in the fields of machining, metal processing, stone processing, etc.

[0003] After a grinding wheel is used for a period of time, the wear on its surface will cause the flatness to be damaged, so dressing is required. The traditional method is to use a grinding block to grind the rotating grinding wheel. However, for ceramic superhard grinding wheels, due to their high hardness, a large force needs to be applied during the grinding process. This force is transmitted to the bearings of the rotating shaft, resulting in an increased bearing load. Long-term use may cause accelerated wear or damage to the bearings. Moreover, during the dressing process, the large force applied may cause the imbalance or increased vibration of the grinding wheel. This vibration will be transmitted through the shaft, affecting the overall stability of the device and reducing the service life. Content of the Utility Model

[0004] The purpose of the utility model is to provide a dressing device for ceramic superhard grinding wheels that can improve the stability of the dressing process and reduce the impact on the rotating shaft.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A dressing device for ceramic superhard grinding wheels includes a workbench. A motor is installed on the lower surface of the workbench, and the end of the rotating shaft of the motor penetrates to the upper side of the workbench. A grinding wheel body is arranged on the outer surface of the rotating shaft of the motor. A toothed ring is rotatably installed on the upper surface of the workbench. Four first vertical plates are coaxially and arrayedly installed on the upper surface of the workbench. A threaded rod is rotatably connected to the outer surface of the first vertical plate. A nut is installed on the outer surface of the threaded rod. A upper side plate is installed on one side of the outer surface of the nut. A grinding block is installed on the outer surface of the upper side plate. A lower side plate is installed on the other side of the outer surface of the nut. A limiting rod is connected to the outer surface of the lower side plate, and the end of the limiting rod penetrates to the other side of the first vertical plate. A transmission mechanism capable of driving the threaded rod to rotate while the toothed ring rotates is arranged on the upper surface of the workbench. A driving mechanism capable of driving the toothed ring to rotate is arranged on the upper surface of the workbench.

[0007] Thus, through the combined use of the transmission mechanism and the driving mechanism, the four threaded rods can be driven to rotate simultaneously. Since the nuts are limited by the limiting rods, when the threaded rods rotate, the nuts can be driven to move along their lengths. Therefore, the four grinding blocks can be driven to simultaneously press against the outer surface of the grinding wheel body, enabling the grinding wheel body to be subjected to forces from multiple directions. This not only greatly improves the shaping efficiency but also reduces the lateral force on the rotating shaft of the motor, enhances the stability of the rotating shaft and the entire device, and improves the usage effect and service life.

[0008] Further, the transmission mechanism includes a connecting shaft rotatably mounted on the upper surface of the workbench. A driving gear is mounted on the outer surface of the connecting shaft, and the driving gear is meshed with a toothed ring. A first bevel gear is mounted on the top of the connecting shaft, and a second bevel gear is mounted at the end of the threaded rod. The first bevel gear is meshed with the second bevel gear.

[0009] When the toothed ring rotates, due to the meshing relationship between the toothed ring and the driving gear, the four connecting shafts can be driven to rotate simultaneously. The connecting shaft drives the first bevel gear to rotate. Since the first bevel gear is meshed with the second bevel gear, the purpose of driving the four threaded rods to rotate simultaneously can be achieved, and the four grinding blocks can be driven to simultaneously press tightly against the outer surface of the grinding wheel body.

[0010] Further, the driving mechanism includes two fixing plates mounted on the upper surface of the workbench. A worm is rotatably connected between the two fixing plates. A worm gear is mounted on the outer surface of one of the connecting shafts, and the worm gear is meshed with the worm.

[0011] When the worm is rotated, due to the meshing relationship between the worm and the worm gear, the current connecting shaft can be driven to rotate. The connecting shaft drives the toothed ring to rotate through the driving gear, and then the toothed ring drives the other three connecting shafts to rotate, enabling the four threaded rods to rotate simultaneously. Moreover, since the worm and the worm gear have good self-locking properties, they can resist the reaction force between the grinding block and the grinding wheel body, preventing loosening between the two and affecting the shaping effect.

[0012] Further, support columns are installed at the four corners of the lower surface of the workbench, and mounting holes are provided at the bottoms of the support columns.

[0013] Through the arrangement of the support columns and the mounting holes, the device can be supported, and the device can be fixed by bolts to ensure its stability during use.

[0014] Further, four second vertical plates are coaxially and arrayedly mounted on the upper surface of the workbench. A support shaft is mounted on the outer surface of the second vertical plate, and the end of the support shaft is rotatably connected to the second bevel gear.

[0015] Through the arrangement of the second vertical plates and the support shafts, a support point can be provided for the other end of the threaded rod, making its structure more stable.

[0016] Further, a plurality of notches are formed on the surface of the workbench, a bottom plate is installed between the four support columns, and a material receiving tray is slidably installed on the surface of the bottom plate.

[0017] When the debris generated after the grinding wheel body is shaped falls on the surface of the workbench, the debris can be swept into the notches and dropped from the notches onto the material receiving tray for collection, which is convenient for cleaning.

[0018] Further, a first handle is installed at the end of the worm, and a second handle is installed on the outer surface of the material receiving tray.

[0019] Through the setting of the first handle, it is convenient to rotate the worm. Through the setting of the second handle, it is convenient to pull out the material receiving tray outward to process the debris inside it.

[0020] Further, rubber pads are arranged on the outer surfaces of the first handle and the second handle, and anti-slip lines are formed on the surfaces of the rubber pads.

[0021] Through the setting of the rubber pads and the anti-slip lines, not only can the hand grip feeling be improved, but also the friction with the hand can be enhanced, reducing the situation of hand slipping. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The present utility model will be described in detail below with reference to the accompanying drawings.

[0029] As Figures 1-5 shown, a ceramic super-hard grinding wheel dressing device includes a workbench 100. A motor 101 is installed on the lower surface of the workbench 100, and the end of the rotating shaft of the motor 101 penetrates to the upper side of the workbench 100. A grinding wheel body 103 is arranged on the outer surface of the rotating shaft of the motor 101. A toothed ring 104 is rotatably installed on the upper surface of the workbench 100. Four first vertical plates 105 are coaxially arranged in an array on the upper surface of the workbench 100. A threaded rod 106 is rotatably connected to the outer surface of the first vertical plate 105. A nut 107 is installed on the outer surface of the threaded rod 106. An upper side plate 108 is installed on one side of the outer surface of the nut 107. A grinding block 109 is installed on the outer surface of the upper side plate 108. A lower side plate 102 is installed on the other side of the outer surface of the nut 107. A limiting rod 110 is connected to the outer surface of the lower side plate 102, and the end of the limiting rod 110 penetrates to the other side of the first vertical plate 105. A transmission mechanism 200 capable of driving the threaded rod 106 to rotate while the toothed ring 104 rotates is arranged on the upper surface of the workbench 100. A driving mechanism 300 capable of driving the toothed ring 104 to rotate is arranged on the upper surface of the workbench 100.

[0030] During use, first install the grinding wheel body 103 on the rotating shaft of the motor 101, then start the motor 101 to drive the grinding wheel body 103 to rotate. Through the transmission cooperation of the transmission mechanism 200 and the driving mechanism 300, the four threaded rods 106 can be driven to rotate simultaneously. Since the nut 107 is limited by the limiting rod 110, when the threaded rod 106 rotates, the nut 107 can be driven to move along its length direction, so that the four grinding blocks 109 can be driven to simultaneously press against the outer surface of the grinding wheel body 103, achieving the purpose of dressing the surface of the grinding wheel body 103. Since the grinding wheel body 103 is simultaneously subjected to forces in multiple directions, not only the dressing efficiency is greatly improved, but also the lateral force on the rotating shaft of the motor 101 is reduced, the stability of the rotating shaft and the entire device is improved, and the use effect and service life are improved.

[0031] Specifically, the transmission mechanism 200 includes a connecting shaft 201 rotatably mounted on the upper surface of the workbench 100. A driving gear 202 is mounted on the outer surface of the connecting shaft 201, and the driving gear 202 is meshed with the toothed ring 104. A first bevel gear 203 is mounted on the top of the connecting shaft 201, and a second bevel gear 204 is mounted on the end of the threaded rod 106. The first bevel gear 203 is meshed with the second bevel gear 204. When the toothed ring 104 rotates, due to the meshing relationship between the toothed ring 104 and the driving gear 202, the four connecting shafts 201 can be driven to rotate simultaneously. The connecting shaft 201 drives the first bevel gear 203 to rotate. Since the first bevel gear 203 and the second bevel gear 204 are meshed with each other, the purpose of driving the four threaded rods 106 to rotate simultaneously can be achieved, and the four grinding blocks 109 can be driven to press against the outer surface of the grinding wheel body 103 at the same time.

[0032] Specifically, the driving mechanism 300 includes two fixing plates 301 mounted on the upper surface of the workbench 100. A worm 302 is rotatably connected between the two fixing plates 301. A worm gear 303 is mounted on the outer surface of one of the connecting shafts 201. The worm gear 303 is meshed with the worm 302. When the worm 302 rotates, due to the meshing relationship between the worm 302 and the worm gear 303, the current connecting shaft 201 can be driven to rotate. The connecting shaft 201 drives the toothed ring 104 to rotate through the driving gear 202, and then the toothed ring 104 drives the other three connecting shafts 201 to rotate, so that the four threaded rods 106 can rotate simultaneously. And because the worm 302 and the worm gear 303 have good self-locking properties, the reaction force between the grinding block 109 and the grinding wheel body 103 can be resisted, and loosening between the two can be avoided, which affects the shaping effect.

[0033] Specifically, support columns 400 are installed at the four corners of the lower surface of the workbench 100. Mounting holes 401 are formed at the bottoms of the support columns 400. Through the settings of the support columns 400 and the mounting holes 401, the device can be supported, and the device can be fixed by bolts to ensure its stability during use.

[0034] Specifically, four second vertical plates 500 are coaxially and arrayedly mounted on the upper surface of the workbench 100. A support shaft 501 is mounted on the outer surface of the second vertical plate 500. The end of the support shaft 501 is rotatably connected to the second bevel gear 204. Through the settings of the second vertical plate 500 and the support shaft 501, a support point can be provided for the other end of the threaded rod 106 to make its structure more stable.

[0035] Specifically, a plurality of notches 600 are formed on the surface of the workbench 100. A bottom plate 601 is installed between the four support columns 400. A material receiving tray 602 is slidably installed on the surface of the bottom plate 601. After the debris generated after the shaping of the grinding wheel body 103 falls on the surface of the workbench 100, the debris can be swept into the notches 600 and fall from the notches 600 onto the material receiving tray 602 for collection, which is convenient for cleaning.

[0036] Specifically, a first handle 700 is installed at the end of the worm 302, and a second handle 701 is installed on the outer surface of the material receiving tray 602. Through the setting of the first handle 700, it is convenient to rotate the worm 302. Through the setting of the second handle 701, it is convenient to pull out the material receiving tray 602 outward to process the debris inside it.

[0037] Specifically, rubber pads are provided on the outer surfaces of the first handle 700 and the second handle 701, and anti-slip lines are formed on the surfaces of the rubber pads. Through the setting of the rubber pads and the anti-slip lines, not only can the hand grip feel be improved, but also the friction with the hand can be enhanced to reduce the situation of hand slipping.

[0038] The above is a detailed description of the present invention in combination with specific embodiments. It cannot be determined that the specific implementation manners of the present invention are only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several equivalent substitutions or obvious modifications are made, and the performance or use is the same, and all should be regarded as belonging to the patent protection scope determined by the claims submitted by the present invention.
