Figure 1 As shown, it includes a turntable 11, a plurality of fixtures 12, a first chamfering mechanism 13 and a second chamfering mechanism 14. Specifically, a plurality of fixtures 12 are fixedly arranged on the turntable 11 along the circumferential direction for clamping the disc brake pad 100 to be processed; the center line of the first chamfering mechanism 13 and the second chamfering mechanism 14 intersects with the moving path of the disc brake pad 100 on the turntable 11;

[0036] The first chamfering mechanism 13, the second chamfering mechanism 14 and the slotting device 2 all include a three-way adjustment module for adjusting the positions of their respective working heads (the working head of the first chamfering mechanism 13 is a chamfering grinding wheel) in the horizontal, longitudinal and vertical directions respectively. When the turntable 11 drives the disc brake pad 100 to rotate to the first angle position and the second angle position respectively, the end surface of the chamfering grinding wheel of the first chamfering mechanism 13 and the end surface of the chamfering grinding wheel of the second chamfering mechanism 14 are respectively parallel to the inner side edges of the chamfers at both ends of the disc brake pad 100, so that the three-way adjustment module of the first chamfering mechanism 13 and the three-way adjustment module of the second chamfering mechanism 14 can adjust the positions of their respective chamfering grinding wheels to grind the chamfers at both ends of the disc brake pad 100 respectively.

[0037] like Figure 5 The figure shows a schematic diagram of the structure of the jig 12. Specifically, the jig 12 includes a support platform 121, an inner arc limit assembly 122 and an outer arc limit assembly 123. The inner arc limit assembly 122 and the outer arc limit assembly 123 are combined on the surface of the support platform 121 to form a clamping area.

[0038] As a specific embodiment, the inner arc limit assembly 122 is a limit plate fixedly arranged on the surface of the support platform 121; the outer arc limit assembly 123 includes a plurality of first telescopic driving members 1231 and a plurality of pressure blocks 1232 corresponding to the first telescopic driving members 1231 one by one, and the plurality of first telescopic driving members 1231 are fixedly distributed on the support platform 121 along the extension direction of the outer arc of the disc brake pad 100; the pressure block 1232 is detachably connected to the output end of the corresponding first telescopic driving member 1231.

[0039] It is easy to understand that after the output ends of several of the first telescopic driving members 1231 are extended respectively, the pressing block 1232 can press the disc brake pad 100 against the side wall of the limiting plate, thereby clamping the disc brake pad 100 from both sides (the inner arc side and the outer arc side of the disc brake pad 100).

[0040] Preferably, the pressing block 1232 is hinged to the output end of the corresponding first telescopic driving member 1231, and the hinge axis is perpendicular to the surface of the supporting platform 121; in this way, the angle of the pressing block 1232 can be adaptively adjusted according to the shape and position of the disc brake pad 100.

[0047] It should be noted that setting the number of the turntables 11 to two is only a preferred embodiment of the present invention, and does not limit the number of the turntables 11 in the present invention. In other embodiments, the number of the turntables 11 can also be set to other numbers, such as 1, 3, etc., but should not exceed the number of required processing steps at most. Specifically, the disc brake pad 100 needs to undergo a total of 5 processes, including the disc brake pad chamfering device 1, the grooving device 2, the disc surface rough grinding device 3, the disc surface fine grinding device 4 and the dust brushing device 6.

[0058] Step 9: After fine grinding is completed, the turntable 11 again moves the disc brake pad 100 to the position corresponding to the dust brushing device 6, and the dust brushing device 6 cleans the dust on the surface of the disc brake pad 100.

[0059] In step 10, after the dust is cleaned, the turntable 11 again transfers the disc brake pad 100 to the position corresponding to the unloading device 8, the fixture 12 releases the disc brake pad 100, and the unloading device 8 unloads the disc brake pad 100. Repeating the above steps can realize batch processing of the disc brake pad 100.

In addition, the disc brake pad combined grinder integrates multiple processes together, thereby enabling multi-process processing of the disc brake pad 100, and the processing efficiency is relatively high.
