Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the present invention.

[0020] like Figure 1-5 As shown in the figure, a two-phase brake pad drilling machine tool with automatic adjustment of the spacing between multiple drill bits in this embodiment includes a brake pad conveying device 1 and a frame 2 disposed on the side of the brake pad conveying device 1. Each of the two vertical surfaces of the frame 2 is provided with a drilling device 3 that can simultaneously process two holes of the brake pads placed vertically on the brake pad conveying device 1. The drilling device 3 includes multiple drilling tables 4 arranged horizontally in the upper and lower dimensions. The frame 2 is provided with a height adjustment mechanism 5 that adjusts the height of the multiple drilling tables respectively.

[0021] The drilling machine 4 includes a base 41, which is provided with two parallel linear guides 42. The two linear guides 42 are slidably connected to a mounting plate 43 via a slider. The base 41 is also provided with a lead screw 44 rotatably connected to the base 41 and a feed motor 45 that drives the lead screw 44 to rotate. The mounting plate 43 is fixed with a lead screw nut 46, which is threadedly connected to the lead screw 44. The mounting plate 43 is also fixed with a drilling motor 47.

[0022] The height adjustment mechanism 5 includes two vertically fixed linear guides 51 fixed to the frame 2. The drilling machine platform 4 is slidably connected to the linear guides 51 via a slider fixed to the base 41. The height adjustment mechanism 5 also includes a lead screw 52 rotatably connected to the frame 2 and a height adjustment motor 53 that drives the lead screw 52 to rotate. The base 41 is fixed with a lead screw nut 54, which is threadedly connected to the lead screw 52.

[0023] When the two height-adjusting motors 53 rotate, they can drive the two drilling platforms 4 to rise and fall respectively, thereby adjusting the height of the two drilling platforms 4 and the distance between them. Because a lead screw is used for adjustment, stepless continuous automatic adjustment can be achieved, greatly improving accuracy and adjustment speed.

[0024] In order to achieve automatic adjustment and precise control, the frame 2 and the drilling machine platform 4 are equipped with a sensing device 6 for sensing the height of the drilling machine platform 4 and sensing the distance between two drilling machine platforms 4. The sensing device 6 can be an infrared rangefinder.

[0025] In this embodiment, a drilling device 3 is installed on each of the two mutually perpendicular surfaces of the frame 2. Each drilling device 3 has a drilling machine base 4 equipped with a drilling motor 47. The drilling motor 47 is equipped with different types and specifications of drill bits, which can perform different processing on the brake pads. For example, according to the transmission direction of the brake pad on the brake pad transmission device 1, when the front drilling device 3 drills a hole in a brake pad, both drilling motors 47 of the front drilling device 3 are equipped with spiral drill bits; when the rear drilling device 3 simultaneously performs countersinking processing on another brake pad, both rear drilling motors 47 are equipped with milling cutters.

[0026] In addition, when the height adjustment mechanism 5 is installed with the frame 2, in order to facilitate leveling, the height adjustment mechanism 5 is installed as a whole on the line gauge seat 7. Specifically, the second line rail 51 is fixed to the line rail seat 7, and the line rail seat 7 is fixedly connected to the frame 2 by screws. At least two wedge-shaped openings 71 are provided on one side of the bottom of the line rail seat 7. A wedge-shaped block 8 for leveling is inserted into the wedge-shaped opening 71 during the installation of the line rail seat 7. The frame 2 is fixed with a support plate 9, and the support plate 9 is threadedly connected to a screw 10 that drives the wedge-shaped block 8 to move.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and for the convenience of describing the technical solution, the front, back, left, right, top, middle, and bottom orientations are based on the accompanying drawings and are not a limitation on the protection scope of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the essence and scope of the technical solution of this utility model.
