[0020] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following further details the present invention in combination with specific embodiments.

[0021] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, a connecting piece for a diamond roller of a grinding machine includes a roller carrier 1 connected to the driving shaft of the grinding machine. One side of the roller carrier 1 is fixedly installed with a roller shaft 4. The other side of the roller carrier 1 is provided with a Morse taper. The diamond roller 2 is sleeved outside the roller shaft 4. A locking block 3 is installed at the end of the roller shaft 4. The locking block 3 is engaged with the diamond roller 2. A plurality of positioning blocks 5 are distributed around one side of the roller carrier 1. A slot 12 corresponding to the positioning block 5 is opened on one side of the diamond roller 2. And a keyway two 11 is opened on the inner wall of the diamond roller 2. A sleeve block 8 is sleeved between the roller shaft 4 and the diamond roller 2. The sleeve block 8 is used for connecting diamond rollers 2 of different specifications with the roller shaft 4. A keyway groove 6 is opened outside the roller shaft 4.

A keyway one 10 corresponding to the spline one 7 is opened on the inner wall of the sleeve block 8. And a plurality of splines two 9 are distributed around the outside of the sleeve block 8. The splines two 9 correspond to the keyway two 11.

[0022] In this embodiment, first confirm whether the inner diameter of the diamond roller 2 matches the diameter of the roller shaft 4. When the diameters match, directly insert the slot 12 on one side of the diamond roller 2 into the positioning block 5 on one side of the roller carrier 1. After rotating the diamond roller 2, make the positioning block 5 engage with the slot 12. At this time, the keyway two 11 in the diamond roller 2 corresponds to the keyway groove 6. Then insert the spline one 7 to connect the diamond roller 2 and the roller shaft 4 into a whole. Install the locking block 3 to complete the installation of the connecting piece and the diamond roller 2. When the inner diameter of the diamond roller 2 matches the outer diameter of the sleeve block 8, after sleeving the diamond roller 2 on the roller shaft 4 and installing it with the roller carrier 1, insert the spline one 7 into the keyway groove 6 in the roller shaft 4, and then insert the sleeve block 8 to make the keyway one 10 in the sleeve block 8 cooperate with the spline one 7, and the splines two 9 outside the sleeve block 8 cooperate with the keyway two 11 to connect the diamond roller 2, the sleeve block 8 and the roller shaft 4 into a whole. Then install the locking block 3 to complete the installation of the connecting piece and the diamond roller 2. Finally, connect the installed diamond roller 2 connecting piece with the driving shaft of the grinding machine. The whole can be applicable to the installation of diamond rollers 2 with different inner diameters, and can be quickly installed and disassembled, while ensuring the connection strength after installation.

[0023] As an embodiment, as Figure 1 、 Figure 2 shown, installation holes 13 are opened at one end of the roller shaft 4 and inside the locking block 3. A locking bolt 14 penetrates through the installation hole 13. The end of the locking bolt 14 is connected to the roller shaft 4.

[0024] In this embodiment, after the diamond roller 2 is connected to the sleeve block 8 and the roller shaft 4 or the diamond roller 2 is directly connected to the roller shaft 4, when the locking block 3 is clamped on the other side of the diamond roller 2 and the mounting holes 13 between the locking block 3 and the roller shaft 4 are aligned, the locking bolts 14 are passed through the mounting holes 13 in the locking block 3 and then cooperate with the mounting holes 13 in the roller shaft 4 for locking, further ensuring the connection strength between the diamond roller 2 and the roller carrier 1 and preventing the diamond roller 2 from shaking during rotation, which may affect the dressing effect.

[0025] As an embodiment, as Figure 2 , Figure 3 and Figure 4 shown, the spline one 7 and the spline two 9 have the same dimensions, and there are at least two groups of the spline one 7 and the keyway one 10. The spline one 7 and the keyway one 10 are symmetrically arranged with the center of the roller shaft 4 as the reference.

[0026] In this embodiment, by using the fact that the spline one 7 and the spline two 9 have the same dimensions, when the inner diameter of the diamond roller 2 matches the diameter of the roller shaft 4, the diamond roller 2 is directly sleeved outside the roller shaft 4. Then, the keyway two 11 in the diamond roller 2 is aligned with the keyway groove 6, and the spline one 7 is inserted into the keyway two 11 to connect the diamond roller 2 and the roller shaft 4 into a whole. When the inner diameter of the diamond roller 2 is larger and matches the outer diameter of the sleeve block 8, after the diamond roller 2 is sleeved on the roller shaft 4 and the roller carrier 1 is installed, the spline one 7 is inserted into the keyway groove 6 in the roller shaft 4, and then the sleeve block 8 is inserted to connect the diamond roller 2, the sleeve block 8 and the roller shaft 4 into a whole, and the installation is selected according to different diamond rollers 2.

[0027] As an embodiment, as Figure 2 , Figure 3 and Figure 4 shown, there are at least four groups of the spline two 9 and the keyway two 11.

[0028] In this embodiment, by using the cooperation of four groups of the spline two 9 and the keyway two 11, the strength of axial fixation is improved, and when the diamond roller 2 is dressed, the force inside the sleeve block 8 is relatively uniform.

[0029] As an embodiment, as Figure 4 shown, the outer diameter of the sleeve block 8 matches the inner diameter of the diamond roller 2, and the inner diameter of the sleeve block 8 matches the outer diameter of the roller shaft 4.

[0030] In this embodiment, when the inner diameter of the diamond roller 2 matches the diameter of the roller shaft 4, the diamond roller 2 and the roller shaft 4 are connected into a whole. When the inner diameter of the diamond roller 2 is larger and matches the outer diameter of the sleeve block 8, the diamond roller 2, the sleeve block 8 and the roller shaft 4 are connected into a whole, which is applicable to diamond rollers 2 with different inner diameters and has a wide application range.

[0031] As an embodiment, as Figure 4As shown, the number of positioning blocks 5 is the same as that of the card slots 12. The positioning blocks 5 are L-shaped, and the bottom ends of the positioning blocks 5 are beveled. By rotating the diamond roller 2, the positioning blocks 5 are screwed and engaged with the card slots 12.

[0032] In this embodiment, when the diamond roller 2 is correspondingly positioned and inserted into the roller carrier 1, by using the combination of the positioning block 5 and the card slot 12, the bevel surface of the positioning block 5 enables the diamond roller 2 to be more quickly engaged with the roller carrier 1. When the diamond roller 2 is rotated by a partial angle, which is the same as the rotation direction connected to the grinding machine drive shaft, the L-shaped positioning block 5 is screwed and engaged into the interior of the card slot 12, improving the connection firmness between the diamond roller 2 and the roller carrier 1 and preventing relative rotation.

[0033] Working principle: During use, first confirm whether the inner diameter of the diamond roller 2 matches the diameter of the roller shaft 4. When the diameters match, directly sleeved the diamond roller 2 outside the roller shaft 4, insert one side card slot 12 of the diamond roller 2 into the positioning block 5 on one side of the roller carrier 1. By using the combination of the positioning block 5 and the card slot 12, rotate the diamond roller 2 by a partial angle to make the positioning block 5 and the card slot 12 be screwed and engaged. At this time, the key slot two 11 in the diamond roller 2 corresponds to the key sliding slot 6, and then insert the spline one 7 to connect the diamond roller 2 and the roller shaft 4 into a whole, install the locking block 3, and quickly complete the assembly of the connecting piece and the diamond roller 2; when the inner diameter of the diamond roller 2 matches the outer diameter of the sleeve block 8, directly insert one side card slot 12 of the diamond roller 2 into the positioning block 5 on one side of the roller carrier 1. After rotating the diamond roller 2, make the positioning block 5 and the card slot 12 engaged. After the engagement, insert the spline one 7 into the key sliding slot 6 in the roller shaft 4, and then insert the sleeve block 8, so that the key slot one 10 in the sleeve block 8 cooperates with the spline one 7, and the spline two 9 outside the sleeve block 8 cooperates with the key slot two 11, connecting the diamond roller 2, the sleeve block 8 and the roller shaft 4 into a whole. Then install the locking block 3 to complete the assembly of the connecting piece and the diamond roller 2. Finally, connect the Morse taper angle on one side of the roller carrier 1 to the grinding machine drive shaft, and drive the diamond roller 2 to rotate by rotating the roller carrier 1 to achieve the control of the dressing speed of the dressing wheel. At the same time, the driving wheel motor is omitted. The whole can be applicable to the installation of diamond rollers 2 with different inner diameters, and at the same time ensure the connection strength after installation.
