Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a brake pad steel back drilling device. Background Art

[0002] Brake pads are the most critical safety parts in the braking system of a car. The quality of all braking effects is determined by the brake pads. Brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The steel plate of the brake pad is the steel back. During the production process of the steel back, it is necessary to drill holes in the side wall of the steel back. The thickness of the steel back is relatively thin, and the side wall of the steel back generally has a certain curvature. The hole diameter of the side wall of the steel back is small and the depth is deep. Therefore, the drill bit used for drilling is relatively thin. The drill bit is easy to slip when drilling holes on the curved side wall, which eventually causes the drill bit to break, affecting the accuracy and efficiency of drilling. Utility Model Content

The workbench 2 is a circular structure, and a rotating downward pressure cylinder is provided on the workbench 2. A pressing plate is provided at the movable end of the rotating downward pressure cylinder, and the steel back is placed on the workbench 2. The downward pressure of the rotating downward pressure cylinder drives the pressing plate downward, so that the pressing plate presses the steel back and fixes the steel back on the workbench 2. A dividing plate is fixedly provided on the frame 1, and the workbench 2 is provided on the dividing plate. The dividing plate can drive the workbench 2 to rotate, and the movement is more precise. The positioning drilling mechanism 14 and the punching drilling mechanism 15 are both provided on the frame 1, and are both located on one side of the workbench 2. The positioning drilling mechanism 14 and the punching drilling mechanism 15 are provided along the circumference of the workbench 2, and the angle between the positioning drilling mechanism 14 and the punching drilling mechanism 15 is 9 0 degrees, first the workbench 2 rotates to move the steel back to one side of the positioning drill mechanism 14, the positioning drill mechanism 14 drills a positioning hole in the side wall of the steel back, after the positioning hole is drilled, the positioning drill mechanism 14 is retracted, the workbench 2 continues to rotate to move the steel back to one side of the punching drill mechanism 15, the punching drill mechanism 15 continues to drill along the positioning hole, due to the presence of the positioning hole, the hole position can be made more accurate during the drilling process, and the drill bit is not easy to slip or break.

[0030] like Figure 1 and Figure 3 As shown, further, in order to better adjust the position of the positioning drilling mechanism 14, the positioning drilling mechanism 14 includes a first base 3, which is slidably arranged on the frame 1, and specifically, a first screw 4 is rotatably arranged on the frame 1, and a motor is fixedly arranged on the frame 1, and the motor is transmission-connected to the first screw 4, and the motor can drive the first screw 4 to rotate, and a first screw nut is threadedly connected to the first screw 4, and the first screw nut is fixedly connected to the first base 3. During the rotation, the first screw 4 can drive the first screw nut and the first base 3 to move along the length direction of the first screw 4, so that the first base 3 is slidably arranged on the frame 1 to achieve position adjustment, and a positioning drilling assembly is rotatably arranged on the first base 3, and the positioning drilling assembly can drill positioning holes on the steel back, and the positioning drilling assembly is rotatably arranged on the first base 3 to achieve angle adjustment of the drilling rig during drilling.

[0031] It should be noted that, since two holes need to be symmetrically drilled on the steel back along the middle vertical section, the positioning drilling mechanism is symmetrically provided with two, the first screw 4 is a bidirectional threaded screw, and the first bases 3 of the two positioning drilling mechanisms are respectively located at the two threads of the first screw 4, so the first screw 4 can drive the two first bases 3 to approach or move away from each other when rotating.

[0032] Furthermore, a first slide rail is fixedly provided on the frame 1, a first slider is fixedly provided on the first base 3, the first slider is slidably provided on the first slide rail, and the first slide rail is provided in parallel with the first lead screw, so that the first base 3 is more stable during sliding.

Specifically, a third lead screw is rotatably arranged on the first connecting plate 5, on which a third lead screw nut is threadedly connected, and the third lead screw nut is fixedly connected to the first support plate 6. A motor is also fixedly arranged on the first connecting plate 5, and the motor is transmission-connected to the third lead screw. When the motor drives the third lead screw to rotate, it can drive the first support plate 6 to slide, so that the first drill 7 can move to the side close to the steel back for drilling, and can also move the first drill 7 to the side away from the steel back to complete the withdrawal of the tool.

[0034] Furthermore, a first turbine is rotatably provided on the first connecting plate 5, the lower end of the first turbine is rotatably connected to the first connecting plate 5, the upper end of the first turbine is fixedly connected to the first support plate 6, and a first worm is also rotatably provided on the first connecting plate 5, the first worm is meshed with the first turbine, and the first worm can drive the first turbine to rotate during rotation, thereby driving the first support plate 6 to rotate, thereby realizing angle adjustment of the first drilling rig 7 on the first support plate 6.

[0035] Furthermore, the drilling rig mechanism 15 has the same structure as the positioning drilling rig mechanism 14, and the drilling rig mechanism 15 includes a second base 8, which is slidably arranged on the frame 1. Specifically, a second screw 9 is rotatably arranged on the frame 1, and a motor is also fixedly arranged on the frame 1. The motor is transmission-connected to the second screw 9, and the motor drives the second screw 9 to rotate. A second screw nut is threadedly connected to the second screw, and the second screw nut is fixedly connected to the bottom of the second base 8. When the second screw 9 rotates, it can drive the second screw nut and the second base 8 to move along the length direction of the second screw 9. The second screw 9 is vertically arranged to the first screw 4, and a drilling rig assembly is rotatably arranged on the second base 8.

[0036] It should be noted that, since two holes need to be symmetrically drilled on the steel back along the middle vertical section, the drilling rig mechanism is symmetrically provided with two, the second screw 9 is a bidirectional threaded screw, and the second bases 8 of the two drilling rig mechanisms are respectively located at the two threads of the second screw 9, so the second screw 9 can drive the two second bases 8 to approach or move away from each other when rotating.

After the drilling is completed, the second support plate 11 drives the second drill rig 12 to move toward the side away from the steel back, thereby causing the drill bit of the second drill rig 12 to detach from the hole.

[0039] It should be noted that the drill bit diameter of the first drill rig 7 is larger than the drill bit diameter of the second drill rig 12, so the drill bit is not easy to break when drilling the positioning hole.
