[0051] When the adjusting motor 304 is driven to rotate circumferentially, the moving seat 307 is moved along the track of the straight slot 303 by the arc-shaped rail slot 306 extruding the moving seat 307, so as to realize the synchronous outward movement or inward movement of the plurality of moving seats 307, the drilling motor 308 and the drill bit 309, thereby realizing the hole drilling operation of different distribution diameters.

[0053] In the present embodiment, when the brake disc 2 is drilled, the operation steps are as follows:

[0054] First, the brake disc 2 is fixed by the three-jaw chuck 105 (it should be noted that the three-jaw chuck 105 is a mature existing device and has been widely used in the field of workpiece machining, and the internal structure and principle of the three-jaw chuck will not be described here), and then the position of the drilling motor 308 can be adjusted according to the distribution diameter of the first group of annularly distributed holes to be drilled.

[0056] When the distribution diameter of the plurality of adjusting motors 304 matches the distribution diameter of the holes to be drilled (that is, the distribution diameter of the drill bit 309 matches the distribution diameter of the holes to be drilled), the operation of the adjusting motor 304 is stopped, and then the rotating motor 106 is started to run at a low speed, the rotating motor 106 drives the outer ring of the slewing bearing 104 to rotate through the driving gear 107, thereby driving the three-jaw chuck 105 and the brake disc 2 to rotate slightly, so as to align the initial drilling position with the drill bit 209, and then stop the rotating motor 106.

[0057] Then, the drilling motor 308 and the vertical electric sliding table 301 are started simultaneously, the drilling motor 308 drives the drill bit 309 to rotate at a high speed, and the vertical electric sliding table 301 drives the lifting circular platform 302, the moving seat 307, the drilling motor 308, and the drill bit 309 to move downward as a whole, the drill bit 309 contacts the brake disc 2 and performs drilling operation, thereby completing the synchronous drilling of the plurality of annularly distributed holes.

[0058] Then, the vertical electric sliding table 301 drives the lifting circular platform 302, the moving seat 307, the drilling motor 308, and the drill bit 309 to move upward as a whole in the reverse direction, and the distribution diameter of the drilling motor 308 is adjusted again according to the above operation steps, and the brake disc 2 is rotated to determine the position of the second group of annularly distributed holes to be drilled, and then the vertical electric sliding table 301 drives the lifting circular platform 302, the moving seat 307, the drilling motor 308, and the drill bit 309 to move downward as a whole, thereby realizing the drilling of the second group of annularly distributed holes.

[0059] According to the above steps, the whole hole drilling can be completed, compared with the traditional hole-by-hole drilling operation mode, the drilling efficiency is faster, the overall operation is simpler, the equipment structure is simple, and the use is convenient.

[0060] Please refer to Figs. 1-4 , the moving seat 307 is composed of a vertical guide column 3071, a limiting circular block 3072 and a linear sliding block 3073;

[0061] The limiting circular block 3072 is symmetrically fixed to the upper and lower ends of the vertical guide column 3071 and is attached to the upper and lower surfaces of the lifting circular table 302 respectively, for realizing the vertical limiting of the vertical guide column 3071;

[0062] The linear sliding block 3073 is symmetrically fixed to the outer side of the vertical guide column 3071 and is in limiting sliding connection with the straight slot 303, and the two linear sliding blocks 3073 are attached to the upper and lower surfaces of the adjusting disc 305 respectively, for realizing the rotating limiting and moving guiding of the vertical guide column 3071;

[0063] The vertical guide column 3071 is slidably sleeved in the inner side of the arc-shaped rail groove 306;

[0064] The vertical guide column 3071 and the limiting circular block 3072 are provided with a through hole for the output end of the drilling motor 308 to penetrate, and the drilling motor 308 is fixedly connected with the upper vertical guide column 3071 through bolts.

[0065] In the embodiment, it should be noted that the outer wall diameter of the limiting circular block 3072 is greater than the width of the straight slot 303, so that the vertical guide column 3071 can be limited to rotate in the vertical direction, and the sliding of the linear sliding block 3073 and the straight slot 303 makes the vertical guide column 3071 only move along the track of the straight slot 303 and cannot rotate, thereby providing stable protection for the operation of the drilling motor 308;

[0066] In addition, the contact surface between the vertical guide column 3071 and the arc-shaped rail groove 306 is arc-shaped, so that the vertical guide column 3071 can be better extruded and moved, ensuring smooth adjustment operation.

[0067] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
