Description

Technical Field

[0001] This utility model relates to the technical field of bonded abrasive wheel processing equipment, specifically, to a device for processing the surface of bonded abrasive wheels. Background Technology

[0002] In the production and processing of bonded abrasive grinding wheels, the surface machining of the grinding wheel is a crucial step. Traditional grinding wheel surface machining devices often suffer from problems such as a single fixing method, inconvenient adjustment, and poor adaptability. Specifically, traditional devices typically use fixed clamps or support structures to fix the grinding wheel. The disadvantage of this method is that it cannot flexibly adjust the position and height of the grinding wheel during machining, resulting in frequent changes of clamps or adjustment devices when machining grinding wheels of different specifications, which seriously affects machining efficiency and product quality.

[0003] Furthermore, in traditional machining devices, the grinding wheels are prone to mutual friction and compression when fixed, which not only increases wear but may also cause impacts, negatively affecting the flatness and overall quality of the grinding wheels. Therefore, a grinding wheel flat surface machining device that is flexibly adjustable, highly adaptable, and can effectively reduce mutual friction and compression between grinding wheels is needed to improve machining efficiency, ensure product quality, and enhance safety during the machining process. Utility Model Content

[0004] The purpose of this utility model is to provide a surface machining device for bonded abrasive grinding wheels, in order to solve the problem mentioned in the background art that the traditional device usually uses a fixed clamp or support structure to fix the grinding wheel. The disadvantage of this method is that it cannot flexibly adjust the position and height of the grinding wheel during the machining process, which leads to the need to frequently change the clamp or adjust the device when machining grinding wheels of different specifications, which seriously affects the machining efficiency and product quality.

[0005] To achieve the above objectives, this utility model provides a surface machining device for bonded abrasive grinding wheels, comprising a disc that matches a grinding wheel, the disc having multiple threaded holes, and a number of bolts, the number of bolts being less than or equal to the number of threaded holes. Each bolt is connected to a threaded hole at a different position for tightening and fixing to the disc. The threaded holes are evenly distributed on the disc, and the bolts are adjusted in height by screwing them into the threaded holes. Several variable-diameter sleeves are fitted on the top of each bolt, and a grinding wheel is mounted on the outside of the variable-diameter sleeves.

[0006] Preferably, the threaded hole is configured to extend through both the top and bottom.

[0007] Preferably, the disc is provided with multiple slots around its perimeter, which are adapted to the positioning protrusions at the edge of the grinding disc for fixing the disc onto the grinding disc.

[0008] Preferably, the bolt includes a threaded rod with a bolt head mounted on the top end of the threaded rod, and the reducing sleeve is fitted onto the bolt head.

[0009] Preferably, the threaded hole includes a hole at the center of the disk, and the remaining holes are arranged in three groups of rings with different diameters around the central hole, with the holes in each group of rings arranged at equal intervals.

[0010] Preferably, several variable diameter sleeves are provided and are sequentially fitted onto the bolt head.

[0011] Preferably, the height of the variable diameter sleeve is less than the height of the finished grinding wheel being processed, and the outer diameter of the variable diameter sleeve is less than the inner diameter of the grinding wheel being processed.

[0012] Preferably, two locking nuts are installed on the screw, and the locking nuts are located at the upper and lower openings of the threaded hole, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this bonded abrasive wheel surface machining device, the height of the grinding wheel can be easily adjusted during machining through multiple evenly distributed threaded holes on the disc, in conjunction with bolts. A variable-diameter sleeve is used to accommodate grinding wheels of different bore diameters. This design not only simplifies the operation when machining grinding wheels of different specifications but also greatly improves machining efficiency and reduces the need for frequent fixture changes or adjustment devices.

[0015] Meanwhile, the device achieves a stable fixation of the disc on the grinding wheel by matching the locating protrusions on the edge of the grinding wheel with the clasps around the disc. By fixing it to different threaded holes with bolts, the position of the grinding wheel can be adjusted at will, ensuring that the spacing between the grinding wheels is sufficient. This effectively reduces the mutual friction and squeezing of the grinding wheels during the processing, reduces the wear and impact risk of the grinding wheels, and thus significantly improves the flatness and overall quality of the grinding wheels.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a device for machining the surface of bonded abrasive wheels, such as... Figures 1-3 As shown, it includes a disc 1 that matches the grinding disc. The disc 1 has multiple threaded holes 2 and a number of bolts 4. The number of bolts 4 is less than or equal to the number of threaded holes 2. Each bolt 4 is connected to a threaded hole 2 at a different position for tightening and fixing to the disc 1. The threaded holes 2 are evenly distributed on the disc 1. The bolts 4 are adjusted in height by screwing them into the threaded holes 2. The top of the bolts 4 is fitted with a number of variable diameter sleeves 43. A grinding wheel 5 is installed on the outside of the variable diameter sleeves 43.

[0023] In this embodiment, the threaded hole 2 is designed to be through from top to bottom, providing sufficient space for vertical adjustment when the bolt 4 is tightened.

[0024] Specifically, the disc 1 is provided with multiple slots 3 around it. The slots 3 are adapted to the positioning protrusions on the edge of the grinding disc to fix the disc 1 on the grinding disc, which facilitates the fixation between the disc 1 and the grinding disc.

[0025] Furthermore, the bolt 4 includes a screw 41, with a bolt head 42 mounted on the top of the screw 41. A reducing sleeve 43 is fitted onto the bolt head 42 to facilitate adjustment of the outer diameter of the bolt head 42 and to adapt to grinding wheels with different hole diameters.

[0026] Furthermore, the threaded hole 2 includes a hole at the center of the disk 1, and the remaining holes are arranged in three groups of rings with different diameters around the central hole. The holes in each group of rings are arranged at equal intervals to ensure that the bolt 4 is fixed at different positions on the disk 1.

[0027] Furthermore, several variable diameter sleeves 43 are provided, which are sequentially fitted onto the bolt head 42 to achieve adjustment of the bolt head 42 to various diameters.

[0028] Furthermore, the height of the reducing sleeve 43 is less than the height of the finished grinding wheel, and the outer diameter of the reducing sleeve 43 is less than the inner diameter of the grinding wheel 5, which facilitates the surface grinding of the grinding wheel 5.

[0029] Furthermore, two locking nuts 44 are installed on the screw 41. The locking nuts 44 are located at the upper and lower openings of the threaded hole 2, respectively, which facilitates the vertical locking and fixation of the screw 41, and the height will not change during the machining of the grinding wheel 5.

[0030] In use, the bonded abrasive wheel surface machining device of this utility model firstly fixes a disc 1 with a diameter matching the machine tool grinding disc to the grinding disc by fitting the positioning protrusions on the edge of the grinding disc with the surrounding jaws 3. Multiple threaded holes 2 are evenly distributed on the disc 1, which are used for installing and fixing bolts 4.

[0031] Next, according to the specifications and processing requirements of the grinding wheel 5, select suitable threaded holes 2 on the disc 1 and screw the bolts 4 into these threaded holes 2. The number of bolts 4 is less than or equal to the number of threaded holes 2, and the height of each bolt 4 can be adjusted by screwing to accommodate grinding wheels 5 of different thicknesses.

[0032] Several reducing sleeves 43 are fitted on the top of the bolt 4. The outer diameter of these reducing sleeves 43 is smaller than the inner diameter of the grinding wheel 5 being processed, and their height is smaller than the height of the finished grinding wheel being processed. By adjusting the number and combination of the reducing sleeves 43, the bolt head 42 can be adjusted to accommodate grinding wheels 5 with different hole diameters.

[0033] Then, the fired grinding wheel 5 is fixed to the disc 1 via its inner hole using bolts 4 and reducing sleeve 43. During fixing, ensure that the grinding wheel 5 and the disc 1 remain stable and perpendicular to each other to guarantee that the machined grinding wheel surface has high precision and flatness.

[0034] The diamond tool of the grinding machine is started, and the grinding wheel 5 is ground. During the grinding process, the inner hole of the grinding wheel 5 is fixed by the screw head and rotates in a circular motion with the rotation of the grinding machine. This fixing method can effectively prevent the grinding wheel 5 from colliding and moving during the processing, improving the safety and convenience of grinding wheel surface.

[0035] Finally, remove the finished surface grinding wheel 5 and blow away the dust and impurities on its surface with an air gun. Then, another batch of grinding wheels 5 can be installed to continue machining the surface. The entire machining process is efficient, stable, and easy to operate, significantly improving the machining efficiency and quality of the grinding wheel surface.
