Description

Technical Field

[0001] This utility model relates to the field of diamond roller technology, specifically a diamond roller that is easy to grind and dress. Background Technology

[0002] Diamond rollers are high-efficiency, long-life, and low-cost grinding wheel dressing tools used in mass production of profile grinding on specialized machine tools and gear grinding machines. Installed on the dressing device of the grinding machine, diamond rollers dress ordinary ceramic or CBN grinding wheels. After the grinding wheel is shaped, the workpiece is ground, thus replicating the shape, precision, and dimensions of the diamond roller onto the surface of the workpiece. Its advantages include simple machine operation, low skill requirements for operators, good consistency in product precision, stable quality, significantly improved production efficiency and product quality, reduced manufacturing costs, and easy automation of grinding processes.

[0003] When installing diamond rollers, they are usually fitted onto the dressing device of the grinding machine through the mounting shaft hole. Then, the diamond rollers and the mounting holes on the dressing device are aligned, and the positions of the two are fixed with connecting bolts to complete the installation of the diamond rollers. However, when aligning the mounting holes, the diamond rollers cover the dressing device, creating blind spots in the field of vision, which makes it difficult to align the mounting holes. Utility Model Content

[0004] The purpose of this invention is to provide a diamond roller that is easy to grind and dress, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a diamond roller that is easy to grind and dress, comprising a roller body, a mounting hole in the middle of the roller body, a mounting shaft hole in the middle of the roller body, positioning grooves on the left and right sides of the mounting shaft hole, a stress surface in the inner wall of the positioning groove, a first heat dissipation hole in the middle of the roller body, and a grinding surface fixedly connected to the surface of the roller body.

[0006] As a further preferred embodiment of this technical solution, there are two mounting holes located on the upper and lower sides of the mounting shaft hole, two stress surfaces formed with the positioning groove to form a trapezoidal surface, multiple first heat dissipation holes, and multiple diamond particles on the surface of the grinding surface.

[0007] As a further preferred embodiment of this technical solution, a first screw hole is provided on the back of the roller body, a connecting bolt is connected to the internal thread of the first screw hole, a mounting plate is movably sleeved on the surface of the connecting bolt, and a second screw hole is provided in the middle of the mounting plate.

[0008] As a further preferred embodiment of this technical solution, the number of the first screw holes is four, and the four first screw holes are evenly distributed in a centrally symmetrical manner. The shape and size of the second screw holes correspond to those of the first screw holes, and the connecting bolt passes through the second screw hole and extends into the interior of the first screw hole.

[0009] As a further preferred embodiment of this technical solution, a slot is provided on the back of the roller body, a heat-conducting block is slidably connected inside the slot, a heat-conducting plate is fixedly connected to the side of the heat-conducting block away from the roller body, and a second heat dissipation hole is provided in the middle of the heat-conducting plate.

[0010] As a further preferred embodiment of this technical solution, the number of the insertion slots is set to four, the shape and size of the heat-conducting block and the insertion slots correspond to each other, and the heat-conducting plate and the mounting plate are fixedly connected.

[0011] As a further preferred embodiment of this technical solution, the second heat dissipation hole and the first heat dissipation hole have corresponding shapes and sizes, and the second heat dissipation hole and the first heat dissipation hole form a heat dissipation air duct.

[0012] This utility model provides a diamond roller that is easy to grind and dress, and has the following beneficial effects:

[0013] (1) When installing the roller body, the positioning groove is aligned with the positioning block on the dressing device. Since both the positioning groove and the positioning block adopt a trapezoidal structure, misalignment will not occur after installation. At the same time, the mounting holes on the roller body and the dressing device are automatically aligned, thereby realizing the rapid installation of the roller body. When the roller body rotates, the inclined stress surface is set inside the positioning groove, so that the interaction force generated at the connection during rotation can be decomposed through the stress surface, thereby increasing the stability of the connection.

[0014] (2) This utility model inserts a heat-conducting block into the inside of the insertion slot and fixes the position of the mounting plate and the roller body with connecting bolts. When the roller body is working, the heat generated during the grinding process can be dissipated through the first heat dissipation hole. At the same time, the heat inside the roller body is conducted to the heat-conducting plate through the heat-conducting block. The second heat dissipation hole and the first heat dissipation hole form a heat dissipation channel, which increases the internal air flow rate when the roller body is working, thereby increasing the heat dissipation effect of the roller body and improving the service life of the roller body.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, a diamond roller that is easy to grind and dress includes a roller body 1, a mounting hole 2 in the middle of the roller body 1, a mounting shaft hole 3 in the middle of the roller body 1, positioning grooves 4 on the left and right sides of the mounting shaft hole 3, a stress surface 5 on the inner wall of the positioning groove 4, a first heat dissipation hole 6 in the middle of the roller body 1, and a grinding surface 7 fixedly connected to the surface of the roller body 1.

[0022] By aligning the positioning groove 4 with the positioning block on the trimming device, since both the positioning groove 4 and the positioning block adopt a trapezoidal structure, misalignment will not occur after installation. At the same time, the roller body 1 and the mounting hole 2 on the trimming device are automatically aligned, thereby realizing the rapid installation of the roller body 1. When the roller body 1 rotates, since the positioning groove 4 has an inclined stress surface 5 inside, the interaction force generated at the connection during rotation can be decomposed through the stress surface 5, thereby increasing the stability of the connection.

[0023] There are two mounting holes 2, located on the upper and lower sides of the mounting shaft hole 3. There are two stress surfaces 5, which together with the positioning groove 4 form a trapezoidal surface. There are multiple first heat dissipation holes 6, and multiple diamond particles are provided on the surface of the grinding surface 7.

[0024] A first screw hole 8 is provided on the back of the roller body 1. A connecting bolt 9 is connected to the internal thread of the first screw hole 8. A mounting plate 10 is movably sleeved on the surface of the connecting bolt 9. A second screw hole 11 is provided in the middle of the mounting plate 10.

[0025] There are four first screw holes 8, which are evenly distributed in a centrally symmetrical manner. The shape and size of the second screw hole 11 correspond to those of the first screw hole 8. The connecting bolt 9 passes through the second screw hole 11 and extends into the interior of the first screw hole 8.

[0026] A slot 12 is provided on the back of the roller body 1. A heat-conducting block 13 is slidably connected inside the slot 12. A heat-conducting plate 14 is fixedly connected to the side of the heat-conducting block 13 away from the roller body 1. A second heat dissipation hole 15 is provided in the middle of the heat-conducting plate 14.

[0027] By inserting the heat-conducting block 13 into the insertion slot 12 and fixing the positions of the mounting plate 10 and the roller body with the connecting bolts 9, the heat generated during the grinding process can be dissipated through the first heat dissipation hole 6 when the roller body 1 is working. At the same time, the heat inside the roller body 1 is conducted to the heat-conducting plate 14 through the heat-conducting block 13. The second heat dissipation hole 15 and the first heat dissipation hole 6 form a heat dissipation air channel, which increases the internal air flow rate when the roller body 1 is working, thereby increasing the heat dissipation effect of the roller body 1 and improving the service life of the roller body 1.

[0028] There are four insertion slots 12. The shape and size of the heat-conducting block 13 and the insertion slot 12 are corresponding. The heat-conducting plate 14 and the mounting plate 10 are fixedly connected.

[0029] The second heat dissipation hole 15 and the first heat dissipation hole 6 have corresponding shapes and sizes, and the second heat dissipation hole 15 and the first heat dissipation hole 6 form a heat dissipation air duct.

[0030] This invention provides a diamond roller that is easy to grind and dress, and its working principle is as follows:

[0031] In use, the heat-conducting block 13 is inserted into the insertion slot 12, and the mounting plate 10 and the roller body are fixed in position using the connecting bolts 9. The positioning slot 4 is aligned with the positioning block on the dressing device. Since both the positioning slot 4 and the positioning block adopt a trapezoidal structure, there will be no misalignment after installation. At the same time, the roller body 1 and the mounting hole 2 on the dressing device are automatically aligned, and the position of the roller body 1 and the dressing device is fixed using screws, thus realizing the quick installation of the roller body 1. When the roller body 1 is working, the heat generated during the grinding process can be dissipated through the first heat dissipation hole 6. At the same time, the heat inside the roller body 1 is conducted to the heat-conducting plate 14 through the heat-conducting block 13. The second heat dissipation hole 15 and the first heat dissipation hole 6 form a heat dissipation air channel, which increases the internal airflow speed when the roller body 1 is working, thereby increasing the heat dissipation effect of the roller body 1.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
