[0041] Embodiment 2

[0042] On the basis of Embodiment 1, the fixing assembly includes: two first electromagnets 402 installed on the side of the drilling fixture plate 4 away from the brake steel back 5; four lower positioning blocks 401 connected to the surface of the drilling fixture plate 4, and an inductor 404 is installed on the surface of the drilling fixture plate 4; a cylinder 204 installed inside the equipment box 2, and an upper positioning block 205 is connected to the bottom of the cylinder 204; a moving groove 206 is opened on one side of the equipment box 2, a moving block 601 is driven and connected on the electric guide rail 6, two telescopic rods 602 are installed inside the moving block 601, one end of the telescopic rod 602 is connected to a top block 603, and a second electromagnet 604 is arranged inside the top block 603. Two openings 501 are opened on the surface of the brake steel back 5, and the positions of the two openings 501 correspond to the positions of the two top blocks 603.

[0043] When drilling the brake steel back 5, the brake steel back 5 can be placed on one side of the moving block 601, and it can be hung on the top block 603 through the openings 501 on the brake steel back 5. At the same time, the second electromagnet 604 is energized to generate a magnetic force to adsorb the brake steel back 5. Then, the moving block 601 is transported to the front of the drilling fixture plate 4 through the electric guide rail 6. Then, the telescopic rod 602 drives the top block 603 and the brake steel back 5 to move towards the drilling fixture plate 4 until the brake steel back 5 contacts the drilling fixture plate 4. At this time, the inductor 404 on the drilling fixture plate 4 senses the brake steel back 5, and the first electromagnet 402 is activated to adsorb the brake steel back 5 on the surface of the drilling fixture plate 4. At the same time, the second electromagnet 604 is demagnetized. Then, the telescopic rod 602 is used to control the separation of the top block 603 from the opening 501, so that the brake steel back 5 stays on the drilling fixture plate 4 and is supported by multiple lower positioning blocks 401. Then, the cylinder 204 drives the upper positioning block 205 to move downwards, so that the upper positioning block 205 presses and fixes the brake steel back 5. Through the settings of the upper positioning block 205, the four lower positioning blocks 401 and the first electromagnet 402, the brake steel back 5 can be fixed up, down, left, right and on the side, and the brake steel back 5 is vertically fixed on the drilling fixture plate 4;

[0044] After the drilling is completed, the top block 603 can be inserted into the opening 501 again through the telescopic rod 602. At this time, the first electromagnet 402 is demagnetized, the second electromagnet 604 is energized to generate a magnetic force, and the cylinder 204 drives the upper positioning block 205 to retract, so that the brake steel back 5 is transferred from the drilling fixture plate 4 to the top block 603 for fixation. Then, the telescopic rod 602 drives the top block 603 and the brake steel back 5 away from the drilling fixture plate 4, and then the brake steel back 5 is sent out of the equipment box 2 through the electric guide rail 6 to complete the clamping and processing cycle of the brake steel back 5.

[0045] Embodiment 3

[0046] On the basis of Embodiment 1, the collection components include: an air pump 3 installed on the top of the equipment box 2; a plurality of slots 101 opened on the surface of the workbench 1, and the plurality of slots 101 are evenly arranged and distributed; a collection frame 701 arranged inside the collection box 7; a fixed box 8 installed between the two collection boxes 7, an air extraction pump 801 is installed inside the fixed box 8, an exhaust pipe 803 is connected to the bottom of the air extraction pump 801, air extraction pipes 802 are connected to both opposite sides of the air extraction pump 801, and the air extraction pipes 802 communicate with the collection box 7, the slots 101 communicate with the collection box 7, a conduit 301 is connected inside the equipment box 2, and the top end of the conduit 301 is connected to the air pump 3, the bottom end of the conduit 301 is connected to a duct 302, and the duct 302 is located above the brake steel back 5.

[0047] Among them, two installation slots 201 are opened inside the equipment box 2, and the two installation slots 201 are inclined towards the brake steel back 5. An electric push rod 202 is installed inside the installation slot 201, and the electric push rod 202 is connected to the electric drill. Two drill bit auxiliary positioning slots 403 are opened at the top of the drilling fixture plate 4.

[0048] After the brake steel back 5 is fixed, drilling operations are carried out. At this time, the electric push rod 202 drives the electric drill 203 to move towards the brake steel back 5, and the electric drill 203 drills the brake steel back 5. The drilling position of the electric drill 203 can be limited through the drill bit auxiliary positioning slots 403 to ensure the drilling accuracy of the electric drill 203. During the drilling process, the air pump 3 compresses the external gas and transports it into the conduit 301, and the compressed gas is sprayed towards the drilling position through the duct 302 to blow away the debris and dust generated by drilling, preventing the debris and dust from accumulating at the drilling position and affecting the hole diameter accuracy of drilling;

[0049] At the same time, the air extraction pump 801 and the air extraction pipes 802 extract the gas inside the collection box 7 and discharge it through the exhaust pipe 803. At this time, a suction force is generated inside the collection box 7, and through the action of the plurality of slots 101 on the inside of the equipment box 2, the floating pulverization and debris inside the equipment box 2 can be sucked into the collection box 7 through the slots 101, reducing the environmental pollution of the work caused by dust floating. At the same time, since the collection frame 701 is composed of a high-mesh filter screen, when the gas drawn into the collection box 7 passes through the collection frame 701, the dust debris in the gas can be isolated and filtered, thereby completing the collection work of the dust debris.

[0050] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0051] The above has introduced in detail an automatic drilling fixture for a brake steel back provided by an embodiment of the present application.
