Description

Technical Field

[0001] This utility model relates to the field of machining tools, and in particular to a diamond dressing roller. Background Technology

[0002] Diamond dressing rollers (or simply diamond rollers) are tools used for dressing grinding wheels in mass production of profile grinding. They offer high efficiency and long service life. Their working principle is as follows: diamond rollers mounted on a grinding machine dress ordinary ceramic-bonded corundum grinding wheels. Once dressed, the grinding wheel can be used to grind the parts. Generally, to achieve precision, the rollers continuously dress the grinding wheel while it grinds the parts. A digital control system compensates for any reduction in the grinding wheel diameter in real time, ensuring that the diamond roller's profile accuracy and feed rate are precisely transmitted to the workpiece.

[0003] Traditional grinding wheel dressing methods have many shortcomings. Diamond dressing rollers have emerged as a high-efficiency and high-precision grinding wheel dressing tool. However, existing diamond dressing rollers still need improvement in terms of structural design, uniformity of diamond distribution, and compatibility with grinding wheels. During long-term dressing, high temperatures can easily be generated, causing accelerated wear and even shedding of the diamond particle layer, affecting the dressing effect and the service life of the roller. Most rollers adopt a one-piece design, resulting in a single shape and size, which makes it difficult to meet the dressing needs of different groove widths and depths, especially in the case of narrow groove processing. Utility Model Content

[0004] The main purpose of this utility model is to provide a diamond dressing roller to solve the many shortcomings of traditional grinding wheel dressing methods in related technologies. Diamond dressing rollers have emerged as an efficient and high-precision grinding wheel dressing tool. However, existing diamond dressing rollers still need improvement in terms of structural design, uniformity of diamond distribution, and compatibility with grinding wheels. During long-term dressing, high temperatures are easily generated, which can accelerate the wear of the diamond particle layer or even cause it to fall off, affecting the dressing effect and the service life of the roller. Most rollers adopt an integrated design, which makes their shape and size uniform and difficult to meet the dressing needs of different groove widths and depths, especially the problem of narrow groove processing.

[0005] To achieve the above objectives, according to one aspect of the present invention, a diamond dressing roller is provided, including an inner dressing roller, a transmission component fixedly connected inside the inner dressing roller, a plurality of triangular grooves being formed inside the inner dressing roller, a plurality of locking blocks being fixedly connected to the transmission component, and a triangular block being fixedly formed at the upper end of each locking block, the triangular block being engaged in the triangular groove.

[0006] Furthermore, the transmission component is coaxially connected to the transmission shaft, a limit block is fixedly installed at one end of the transmission shaft, the surface of the locking block is provided with a convex structure, and the surface of the triangular block is provided with several protrusions.

[0007] Furthermore, both ends of the inner dressing wheel are provided with internal threads, and one side of the outer dressing wheel is provided with external threads; the inner dressing wheel is threadedly connected to the outer dressing wheel through the internal and external threads.

[0008] Furthermore, outer dressing wheels are provided on both sides of the inner dressing wheel.

[0009] Furthermore, both sides of the inner dressing wheel are provided with inner bolt holes, and the outer dressing wheel is provided with outer bolt holes on its outer side; both the outer bolt holes and the inner bolt holes are threaded with bolts.

[0010] Furthermore, a layer of diamond particles is fixedly installed on the outer surface of the outer dressing wheel.

[0011] Furthermore, a nut is provided on the outside of the outer bolt hole, and the nut is fixedly connected to the outer dressing wheel.

[0012] Compared with the prior art, the present invention has the following advantages: as a high-efficiency and high-precision grinding wheel dressing tool, the diamond dressing roller can change the shape and size of the roller through the threaded connection and bolt connection between the outer dressing roller and the inner dressing roller;

[0013] When the rollers wear out or the groove width of the workpiece needs to be changed, simply adjust the distance between the threaded bolts between the outer and inner dressing wheels to adjust the width of the grinding groove. This device is especially suitable for narrow groove grinding and meets diverse grinding wheel dressing needs.

[0014] By setting up locking blocks, the connection between the inner and outer dressing wheels can be made more secure. On the other hand, an air duct can be formed between the two locking blocks. The air duct helps to dissipate the heat generated when the outer and inner dressing wheels rotate, which solves the problem that the high temperature generated during long-term dressing can lead to accelerated wear or even detachment of the diamond particle layer, thus affecting the dressing effect and the service life of the roller.

[0019] To further illustrate the technical means and effects adopted by the utility model in order to achieve the intended purpose of the utility model, the following detailed description of the specific implementation methods, structure, features and effects of the utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] Please see Figures 1-3 As shown, the purpose of this embodiment is to provide a diamond dressing roller, including an inner dressing roller 2, a transmission component 3 fixedly connected inside the inner dressing roller 2, a plurality of triangular grooves 23 opened inside the inner dressing roller 2, and a plurality of locking blocks 4 fixedly connected to the transmission component 3.

[0021] Each of the card blocks 4 has a fixed triangular block 41 at its upper end. The triangular block 41 is engaged in the triangular groove 23. The transmission component 3 is coaxially connected to the transmission shaft. A limit block is fixedly installed at one end of the transmission shaft. The card block 4 has a convex structure on its surface, and the triangular block 41 has several protrusions on its surface.

[0022] The triangular block 41 at the upper end of the locking block 4 is engaged in the triangular groove 23 to fix it. The airflow generated at the lower end of the locking block 4 during rotation can dissipate heat from the inside of the diamond dressing roller.

[0023] The limit block is used to limit the movement of the dressing wheel;

[0024] The rotation of the drive shaft drives the transmission component 3 to rotate, and the inner dressing wheel 2 rotates through the engagement between the triangular block 41 and the triangular groove 23.

[0025] The purpose of the protrusion is, on the one hand, to increase the friction between the triangular block 41 and the triangular groove, and on the other hand, to create a gap between the triangular block 41 and the triangular groove, which can play a certain role in heat dissipation.

[0026] It should be noted that the dimensions of the triangular block 41 are the same as the dimensions of the triangular groove 23;

[0027] There are at least six clips 4 to ensure that multiple air channels are provided between the clips 4 when the clips 4 are rotated by the transmission component 3. The convex surface on the clips 4 can also form several air channels, so that when the dressing wheel rotates, the heat inside the dressing wheel is dissipated from the convex surface and discharged into the air channels between the clips 4, and finally dissipated. The convex surface can dissipate heat more quickly, which is beneficial to extending the service life of the diamond dressing roller.

[0028] Meanwhile, the heat dissipation of the contrast surface is a planar structure, which can limit the heat dissipation direction of the dressing wheel and prevent the heat dissipation directions between the two card blocks 4 from not intersecting, thereby affecting the heat dissipation efficiency of the dressing wheel.

[0029] The outer dressing wheel 1 has a diamond particle layer 11 fixedly installed on its outer surface. The inner dressing wheel 2 has internal threads 21 at both ends. The inner dressing wheel 2 has outer dressing wheels 1 on both sides. The outer dressing wheel 1 has external threads 13 on one side of its inner side. The inner dressing wheel 2 is threadedly connected to the outer dressing wheel 1 through the internal threads 21 and the external threads 13.

[0030] The diamond particle layer 11 is used to continuously dress the grinding wheel during rotation;

[0031] The inner dressing wheel 2 rotates, which drives the outer dressing wheel 1 to rotate. The diamond particle layer 11 on the surface of the outer dressing wheel 1 continuously dresses the grinding wheel.

[0032] It should be noted that the outer dressing wheel 1 is rotated and tightened on the inner dressing wheel 2 in the opposite direction to the rotation of the drive shaft, to prevent the outer dressing wheel 1 from falling off the inner dressing wheel 2 during rotation.

[0033] The outer dressing wheel 1 has an outer bolt hole 12 on one side, and the inner dressing wheel 2 has an inner bolt hole 22 on both sides. The outer bolt hole 12 and the inner bolt hole 22 are threaded with bolts 14. A nut is provided on the outside of the outer bolt hole 12, and the nut is fixedly connected to the outer dressing wheel 1.

[0034] Bolt 14 is used to perform secondary fixation on the outer dressing wheel 1 and the inner dressing wheel 2, based on the fixation of the inner thread 21 and the outer thread 13;

[0035] The top of the bolt 14 adopts a snap-fit ​​structure. The bolt 14 is threadedly connected to the outer bolt hole 12 and the inner bolt hole 22, so that the outer dressing wheel 1 and the inner dressing wheel 2 fit tightly together.

[0036] The nut adopts a double-sided snap-fit ​​structure. When the part is not ground, the nut snaps into the outer bolt hole 12. When the outer bolt hole 12 is not threaded with the bolt 14, it prevents impurities from entering the outer bolt hole 12 and affecting the threaded connection between the outer bolt hole 12 and the bolt 14.

[0037] During the grinding of the part, one side of the nut is engaged with the limiting component, and the other side is engaged with the bolt 14;

[0038] It should be noted that the inner diameter of bolt 14, the diameter of outer bolt hole 12, and the diameter of inner bolt hole 22 are the same. The direction of rotation and tightening of bolt 14 in outer bolt hole 12 and inner bolt hole 22 is opposite to the rotation of the drive shaft to prevent bolt 14 from falling off during grinding of the parts.

[0039] The outer dressing wheel 12 is internally connected to the outer thread of the inner dressing wheel 2 via internal thread 21 and external thread 13. The bolt 14 is threadedly connected to the outer bolt hole 12 inside the outer dressing wheel 12 and the inner bolt hole 22 inside the inner dressing wheel 2, thus fixing the outer dressing wheel 12 to the inner dressing wheel 2. Therefore, it supports quick replacement of the outer dressing wheel, can adapt to the dressing needs of narrow grooves between 0.5-5mm, reduce equipment downtime, and increase grinding efficiency to a certain extent.

[0040] Furthermore, the threaded connection between the internal thread 21 and the external thread 13 and the threaded connection between the bolt 14, the external bolt hole 12 and the internal bolt hole 22, allows the outer dressing wheel 12 and the inner dressing wheel 2 to be doubly fixed, greatly improving the vibration resistance performance, thereby ensuring that there is no misalignment of the components of the diamond dressing roller when grinding the parts.

[0041] In practical use, the drive shaft rotates, which drives the transmission component 3 to rotate, and then drives the locking block 4 to rotate the inner trimming wheel 2. The triangular block 41 at the upper end of the locking block 4 is locked in the triangular groove 23 to play a fixing role. During the rotation of the two locking blocks 4, the airflow generated between their lower ends can dissipate heat from the outer trimming wheel 1 and the inner trimming wheel 2. The limiting block limits the trimming wheel.

[0042] The exposed part of the card block 4 has several convex surfaces. On the one hand, it increases the friction between the triangular block 41 and the triangular groove. On the other hand, it can create a gap between the triangular block 41 and the triangular groove to play a certain role in heat dissipation. This ensures that when the card block 4 is driven to rotate by the transmission component 3, multiple air channels are provided between the card blocks 4. The convex surfaces on the card block 4 can also form several air channels, so that when the dressing wheel rotates, the heat inside the dressing wheel is dissipated from the convex surfaces and discharged into the air channels between the card blocks 4, and finally dissipated. Moreover, the convex surfaces can dissipate heat more quickly. At the same time, compared with the heat dissipation of the flat surface, it can limit the heat dissipation direction of the dressing wheel and prevent the heat dissipation directions between the two card blocks 4 from intersecting, thereby affecting the heat dissipation efficiency of the dressing wheel.

[0043] Because the inner dressing wheel 2 is threadedly connected to the outer dressing wheel 1 through the inner thread 21 and the outer thread 13, and the outer bolt holes 12 on the outer side of the outer dressing wheel 1 and the inner bolt holes 22 on both sides of the inner dressing wheel 2 are threadedly connected by bolts 14, the outer dressing wheel 12 and the inner bolt holes 22 are threadedly connected, so that the outer dressing wheel 12 and the inner dressing wheel 2 are doubly fixed, and the vibration resistance is greatly improved. This ensures that there is no misalignment of the components of the diamond dressing roller when grinding the parts, and supports quick replacement of the outer dressing wheel. It can adapt to the narrow groove dressing needs between 0.5-5mm, reduce equipment downtime, and increase grinding efficiency to a certain extent.

[0044] Bolt 14 provides secondary fixation to the outer dressing wheel 1 and inner dressing wheel 2, which are fixed by the internal thread 21 and the external thread 13. When the part is not being ground, the nut engages with the outer bolt hole 12. When the outer bolt hole 12 is not threaded with the bolt 14, this prevents impurities from entering the outer bolt hole 12 and affecting the threaded connection between the outer bolt hole 12 and the bolt 14. During the grinding of the part, one side of the nut engages with the limiting component, and the other side engages with the bolt 14. This causes the inner dressing wheel 2 to rotate while driving the outer dressing wheel 1 to rotate. The diamond particle layer 11 on the surface of the outer dressing wheel 1 continuously dresses the grinding wheel.

[0045] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
