Description

Technical Field

[0001] The invention relates to the field of brake pad devices, and in particular to a brake pad punching device. Background Art

[0002] Automobile brake pads, also known as automobile brake leathers, refer to friction materials fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and friction lining block bear external pressure and generate friction to achieve the purpose of vehicle deceleration. Automobile brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The steel plates must be painted to prevent rust. The SMT-4 furnace temperature tracker is used to detect the temperature distribution of the coating process to ensure quality. During the processing of automobile brake pads, drilling equipment is required to drill holes in the automobile brake pads.

[0003] Patent application number: CN202222049871.5 discloses a brake pad drilling device, including a load-bearing plate, a group of support legs are fixedly connected to the bottom surface of the load-bearing plate, the bottom ends of the support legs are all installed with bases, a feed hole is opened on the upper surface of the load-bearing plate, a load-bearing frame is arranged above the load-bearing plate, a group of support columns are installed on the bottom surface of the load-bearing frame, the bottom end of each support column is fixedly connected to the upper surface of the load-bearing plate, a drilling assembly is installed inside the support frame, the drilling assembly includes a mounting plate slidably connected to the inner wall of the support frame and an electric push rod embedded in the upper surface of the support frame, the output end of the electric push rod is fixedly connected to the upper surface of the mounting plate, a motor is installed on the bottom surface of the mounting plate, and a drill is installed on the output end of the motor. The drill is used to drill holes in the brake pad, but after the drill comes into contact with the brake pad, a large amount of heat is generated at the drill position, which is easy to damage the drill.

[0004] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a brake pad punching device.

[0006] The present invention can be implemented by the following technical solutions:

[0007] The present invention discloses a brake pad punching device, comprising a water tank, wherein a plurality of support columns are vertically fixed in the water tank, a support plate is also provided in the water tank, the support column passes through the support plate and is slidably connected to the support plate, a plurality of support springs are also fixed in the water tank below the support plate, a plurality of slide rails are fixed on the support plate, a slide table is also provided above the support plate, a plurality of threaded columns are also fixed on both sides of the slide table, fixed blocks are provided on both sides above the slide table, the threaded columns pass through the fixed blocks at corresponding positions and are slidably connected to the fixed blocks, a nut threadedly connected to the threaded columns is also provided on the threaded columns above the fixed blocks, a sliding rod and a screw rod are also provided on the water tank on one side of the support plate, and the screw rod is driven by a positioning motor The screw rod is driven to rotate, and a sliding block is also provided on the screw rod, and the screw rod passes through the sliding block and is threadedly connected to the sliding block, and the sliding block passes through the sliding block and is slidably connected to the sliding block, and a push rod is fixed on the sliding block, and the push rod passes through the sliding table and is slidably connected to the sliding table, and a lifting cylinder is fixed on the sliding block, and a pressure plate is fixed at the end of the piston rod of the lifting cylinder, and a support rod and a screw rod are also provided on the water tank, and the screw rod is driven to rotate by a limit motor, and a sliding block is also provided on the screw rod, and the screw passes through the sliding block and is threadedly connected to the sliding block, and the support rod passes through the sliding block and is slidably connected to the sliding block, and a punching cylinder is fixed on the sliding block, and a punching motor is fixed at the end of the piston rod of the punching cylinder, and a drill bit is fixed at the output end of the punching motor.The water tank is filled with coolant, the brake pad to be punched is placed on the slide, and the nut is turned. Since the nut is threadedly connected to the threaded column, when the nut is rotated, the nut moves downward, and the nut contacts the fixed block and squeezes the fixed block downward, and the brake pad is fixed to the slide through the fixed block. After the brake pad is fixed, the positioning motor drives the screw rod to rotate. Since the screw rod is threadedly connected to the slide, when the screw rod rotates, the slide moves in the direction of the screw rod, and the push rod pushes the slide to move on the support plate. After the brake pad moves to the specified position with the slide, the positioning motor stops, the lifting cylinder starts, the piston rod of the lifting cylinder extends, the pressure plate descends, and the pressure plate contacts the support plate and pushes the support plate to descend. The brake pad descends with the support plate. After the brake pad enters the coolant, the screw is driven to rotate by the limit motor. When the screw rotates, the slider moves in the direction of the screw, the drill bit moves with the slider, and the drill bit reaches the position to be punched on the brake pad. After the position is directly above, the drilling cylinder starts, the piston rod on the drilling cylinder extends, the drill bit descends, and the drill bit is driven to rotate by the drilling motor. After the drill bit contacts the brake pad, the brake pad is drilled. After the drilling is completed, the drilling cylinder starts, the piston rod on the drilling cylinder shortens, and the drill bit rises. After the drill bit is separated from the brake pad, the lifting cylinder starts, the piston rod on the lifting cylinder shortens, the pressure plate rises, and the support spring pushes the support plate to rise. The brake pad rises with the support plate. After the brake pad is separated from the coolant, the positioning motor drives the screw rod to rotate in the opposite direction, the slide plate returns to the initial position, and the push rod drives the slide table back to the initial position. The drilled brake pad is removed. When drilling a hole in the brake pad, the brake pad is pressed into the coolant, and the drill bit enters the coolant to drill a hole in the brake pad. The heat generated by the drill bit drilling is absorbed by the coolant to avoid damage to the drill bit and effectively absorb the dust generated by drilling the brake pad.

[0008] Preferably, a plurality of fixing springs are fixed between the fixing block and the slide. When the brake pad is removed, the nut is rotated, and when the nut rises, the fixing spring pushes the fixing block to rise, and the fixing block is separated from the brake pad, so that the brake pad can be removed more conveniently.

[0009] Preferably, a plurality of fixing columns are fixed in the water tank below the support plate. When the support plate descends, it reaches above the fixing columns, and the support plate is supported by the fixing columns.

[0010] Preferably, an arc-shaped limiting plate is fixed in the water tank, and a plurality of supporting wheels are fixed at the bottom of the supporting plate. When fixing and removing the brake pad, the supporting plate is supported by the limiting plate, which facilitates fixing and removing the brake pad.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] When drilling holes in brake pads, the brake pads are pressed into the coolant, and the drill bit enters the coolant to drill holes in the brake pads. The coolant absorbs the heat generated by the drill bit to avoid damage to the drill bit, and can effectively absorb the dust generated by drilling holes in the brake pads.
