[0040] Furthermore, the first chamfering mechanism 12, the second chamfering mechanism 13 and the slotting device 2 also include a two-way adjustment module (not shown in the figure), which is used to adjust the position of their respective working heads (the working head of the slotting device 2 is the slotting grinding wheel) vertically and perpendicular to the direction of the first material moving mechanism 11.

[0041] like Figure 5 The figure shows a schematic diagram of the structure of the first tool 14. In order to realize that the first tool 14 can drive the disk 1000 to rotate to any angle, the first tool 14 includes a tool assembly 141 and a rotation drive assembly 142.

[0042] Preferably, the first chamfering mechanism 12 and the second chamfering mechanism 13 are respectively distributed on both sides of the first material moving mechanism 11 and along the extension direction of the first material moving mechanism 11, so that the rotating drive assembly 142 can rotate a smaller amplitude so that the disc 1000 can reach a preset angle position.

[0043] Please continue to refer to Figure 5 Furthermore, the tooling assembly 141 includes a discharge platform 1411, an inner arc limiting structure 1412 and an outer arc limiting structure 1413, and the inner arc limiting structure 1412 and the outer arc limiting structure 1413 are combined to form a positioning area on the surface of the discharge platform 1411.

[0045] Preferably, in order to enable the pressing block 14132 to be applicable to the discs 1000 of various shapes, the pressing block 14132 is hinged to the output end of the corresponding first telescopic driving member 14131 , and the hinge axis is perpendicular to the surface of the unloading platform 1411 .

[0046] Furthermore, in order to improve the positioning effect of the disc 1000 on the unloading platform 1411, the tooling assembly 141 also includes a first end limiting structure 1414 and a second end limiting structure 1415 that are relatively arranged, and the first end limiting structure 1414 is a limiting block fixedly arranged on the surface of the unloading platform 1411, and the second end limiting structure 1415 includes a second telescopic driving member 14151 and an abutment block 14152, and the second telescopic driving member 14151 is fixedly arranged on the unloading platform 1411, and the abutment block 14152 is fixedly connected to the output end of the second telescopic driving member 14151.

[0047] Specifically, the first telescopic drive member 14131 and the second telescopic drive member 14151 may be a cylinder or a hydraulic cylinder. Preferably, in order to prevent the first telescopic drive member 14131 and the second telescopic drive member 14151 from affecting the processing operation of the disc 1000, the first telescopic drive member 14131 and the second telescopic drive member 14151 are both fixedly disposed at the bottom of the unloading platform 1411.

[0049] It is easy to understand that since the disc chamfering grinding device 1 and the grooving device 2 both have angle requirements for the placement state of the disc 1000, while the disc surface rough grinding device 3, the disc surface fine grinding device 4 and the disc surface brushing device 5 have no angle requirements for the placement state of the disc 1000, according to this difference, the grooving device 2 and the disc chamfering grinding device 1 are distributed along the extension direction of the first material moving mechanism 11, and the disc surface rough grinding device 3, the disc surface fine grinding device 4 and the disc surface brushing device 5 are distributed sequentially along the extension direction of the second material moving mechanism 62, so that the grooving device 2 and the disc chamfering grinding device 1 share the first tooling 14, and the disc surface rough grinding device 3, the disc surface fine grinding device 4 and the disc surface brushing device 5 share the second tooling 14', the number of the first tooling 14 and the second tooling 14' in the disc combination grinder can be reduced.

[0050] In particular, since both the first tooling 14 and the second tooling 14 ′ are used to clamp the disk 1000 , the second tooling 14 ′ can be obtained by removing the rotation drive assembly 142 from the first tooling 14 .

[0051] Preferably, in order to improve the production cycle, the first material moving mechanism 11 and the second material moving mechanism 62 are both designed as reciprocating moving mechanisms. The first material moving mechanism 11 is used to drive the first tool 14 to reciprocate between the first position and the second position, and the slotting device 2 and the disc chamfering grinding device 1 are distributed between the first position and the second position along the extension direction of the first material moving mechanism 11;

[0053] The transfer mechanism 61 is used to transfer the disk 1000 on the first tooling 14 located at the second position to the second tooling 14 ′ located at the third position.

[0054] Further, in order to cooperate with the reciprocating second material moving mechanism 62, the disc combination grinding machine also includes a first transfer device 7 and a second transfer device 8 respectively arranged at the fifth position and the sixth position, the fifth position is located between the disc surface rough grinding device 3 and the disc surface fine grinding device 4, the sixth position is located between the disc surface fine grinding device 4 and the disc surface dust brushing device 5, the first transfer device 7 and the second transfer device 8 divide the distance between the third position and the fourth position into three equal sections, and the second material moving mechanism 62 moves a distance length each time;

[0055] The second tooling 14' is sequentially arranged in three pieces along the extension direction on the second material transfer mechanism 62, namely, the second tooling a 14'a, the second tooling b 14'b, and the second tooling c 14'c; the first transfer device 7 is used for grabbing the disk 1000 on the second tooling a14'a moved to the fifth position, and placing it on the second tooling b 14'b returned to the fifth position; the second transfer device 8 is used for grabbing the disk 1000 on the second tooling b14'b moved to the sixth position, and placing it on the second tooling c 14'c returned to the sixth position.

[0056] According to an embodiment of the present invention, the disc assembly grinding machine further includes a loading device and an unloading device (not shown in the figure), wherein the loading device is used to load the disc 1000 to be processed onto the first tooling 14 located at the first position, and the unloading device is used to unload the disc 1000 on the second tooling 14' located at the fourth position. Specifically, the loading device and the unloading device may be a loading robot and an unloading robot, respectively.

[0057] In order to facilitate the understanding of this scheme, the following Figure 1-Figure 5 The working principle of the present invention is described in detail:

[0058] In step 1, the loading device loads the disc 1000 to be processed onto the first tooling 14 located at the first position.

[0059] In step 2, the rotation drive assembly 142 is started to adjust the disc 1000 on the first tooling 14 to a preset slotting angle, and the first material moving mechanism 11 and the slotting device 2 are started to slot the surface of the disc 1000.

[0060] Step 3, start the disc chamfer grinding device 1, after the rotary drive assembly 142 adjusts the disc 1000 to the first angle position, the first chamfering mechanism 12 cooperates with the first material shifting mechanism 11 to grind the chamfer of the first end of the disc 1000; after the rotary drive assembly 142 adjusts the disc 1000 to the second angle position again, the second chamfering mechanism 13 cooperates with the first material shifting mechanism 11 to grind the chamfer of the second end of the disc 1000. After the chamfer grinding of both ends of the disc 1000 is completed, the disc 1000 comes to the second position.

[0061] In step 4, the transfer mechanism 61 transfers the disk 1000 on the first tooling 14 at the second position to the second tooling a 14'a at the third position.

[0062] Step 5: start the second material moving mechanism 62 and the disc rough grinding device 3, and the disc rough grinding device 3 cooperates with the second material moving mechanism 62 to rough grind the upper surface of the disc 1000. After the rough grinding is completed, the second tooling a 14'a and the disc 1000 come to the fifth position.

[0063] Step 6: After the first transfer device 7 grabs the disk 1000 on the second tooling a14'a at the fifth position, the second material moving mechanism 62 moves in the reverse direction to the initial position to return the second tooling a14'a to the third position.

[0064] In step 7, the first transfer device 7 places the grabbed disk 1000 on the second tooling b 14'b at the fifth position.

[0065] Step 8: Start the disc surface fine grinding device 4, which cooperates with the second material moving mechanism 62 to fine grind the upper surface of the disc 1000. After the rough grinding is completed, the second tool b 14'b and the disc 1000 come to the sixth position.

[0066] In step 9, after the second transfer device 8 grabs the disk 1000 on the second tooling b14'b at the sixth position, the second material transfer mechanism 62 moves in the reverse direction to the initial position, so that the second tooling b14'b returns to the fifth position.

[0069] In step 12, the unloading device is started to unload the disc 1000 on the second tool c 14'c at the fourth position.

[0070] In summary, in a disc chamfering grinding device and a disc combination grinding machine provided by the present invention, the first tooling 14 can drive the disc 1000 clamped thereon to rotate and switch to a first angle position and a second angle position, so that the chamfered inner side edge of one end of the disc 1000 at the first angle position is parallel to the chamfering grinding wheel end face of the first chamfering mechanism 12, and the chamfered inner side edge of the other end of the disc 1000 at the second angle position is parallel to the chamfering grinding wheel end face of the second chamfer 13, thereby achieving The two chamfers with non-parallel inner edges of the disc 1000 are ground; in addition, since the disc chamfer grinding device 1 and the slotting device 2 both have angle requirements for the placement state of the disc 1000, the slotting device 2 and the disc chamfer grinding device 1 are distributed along the extension direction of the first material moving mechanism 11 so that the slotting device 2 and the disc chamfer grinding device 1 share the first tooling 14, the number of the first tooling 14 in the disc combination grinder can be reduced.
