Description

Technical Field

[0001] The invention relates to the technical field of punching devices, in particular to a punching device for processing a car brake disc. Background Art

[0002] Disc brake discs are divided into solid discs (single-piece discs) and duct discs (double-piece discs). Duct discs have the function of ventilation. They have many holes on the circumference leading to the center of the circle, called ducts. When the car is driving, air convection in the ducts can achieve the purpose of heat dissipation. Compared with solid discs, the heat dissipation effect is better. Most cars are front-wheel drive, and the front discs are more frequently worn, so front duct discs are used.

[0003] The vibration generated by the existing air duct disc during punching can easily cause the heat dissipation holes to deviate, thereby causing the drill bit to wear the solid part of the air duct disc. The overall strength of the brake pad may be affected to a certain extent, causing the brake pad to be more easily deformed or damaged when subjected to force. If the heat dissipation holes on the brake pad are unevenly distributed or the punching accuracy is not high, it may affect the dynamic balance of the brake disc and thus affect driving safety. Burr defects may occur during the punching process, which will affect the friction performance and assembly accuracy of the brake pad. For this reason, we propose a punching device for automobile brake discs. Summary of the invention

Chamfering the edges of the heat dissipation holes can reduce the risk of cracking or breaking of the brake pads due to stress concentration during use. Through the cooperation between the first pressure rod and the limit strip, the first motor drives the sliding block to align with the ventilation slot below, so that the punching drill can accurately align with the ventilation slot for punching.

Through the cooperation between the clamping block and the telescopic air pipe, the airflow can impact the inside of the ventilation slot when punching the brake disc body to remove internal debris, and use the airflow to cool the punching drill bit to increase the service life of the punching drill bit. The second electric telescopic rod pushes the oil tank to slide in the first slide slot, so that the position of the next heat dissipation hole can be accurately calibrated above the ventilation slot, avoiding the deflection of the punching drill bit, avoiding the misalignment of the heat dissipation holes, and keeping the punching position stable.

[0017] 3. Through the cooperation between the first slide bar and the third slide groove, the lubricating oil is output outward through the output hole, so that the punching drill bit is gradually lubricated by the lubricating oil through the oil delivery groove to form a lubricating film, thereby significantly reducing the friction and resistance between the punching drill bit and the brake disc body, thereby reducing the high temperature generated during cutting, and avoiding overheating, deformation, wear and even breakage of the punching drill bit. By reducing friction and heat, the lubricating oil helps to protect the drill bit, extend its service life, and reduce the cost of replacement and maintenance. It can also make the punching drill bit more stable during the cutting process through lubrication, reduce errors caused by friction and vibration, and improve processing accuracy. Due to the reduction in friction, the resistance of the drill bit during the cutting process is reduced, making the work speed faster and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In this embodiment, the punching mechanism 5 includes a sliding block 51 slidably connected to the first pressure rod 44, a first spring 52 is arranged on the outer side of the first pressure rod 44 at the upper end of the sliding block 51, one end of the first spring 52 is fixedly connected to the first pressure rod 44, and the other end of the first spring 52 is fixedly connected to the sliding block 51, and the upper end of the sliding block 51 is fixedly connected to a fixing rod 53 near both ends, and the upper end of the fixing rod 53 is fixedly connected to a limiting block 54, and the outer side of the limiting block 54 is slidably connected to a mounting block 56, and the outer side of the mounting block 56 is provided with a second slide groove 58 near the front and rear ends, and the inner side of the second slide groove 58 is slidably connected to the fixing rod 53. An L-shaped slide plate 59 is connected, and the ends of the two groups of L-shaped slide plates 59 that are close to each other are commonly fixedly connected to a fixing plate 512. A second motor 510 is installed on the upper end of the fixing plate 512. The output shaft of the second motor 510 is fixedly connected to a connecting shaft 511. The lower end of the connecting shaft 511 is fixedly connected to a punching drill bit 513. An isolation groove 521 is provided on the upper end of the punching drill bit 513.

One end of the second spring 55 is fixedly connected to the limit block 54, and the other end of the second spring 55 is fixedly connected to the mounting block 56.

[0029] Specifically, when the first pressure rod 44 moves downward, the tension of the first spring 52 drives the sliding block 51 to move downward. When the pressure plate 45 gradually approaches the placement pile 6, the sliding block 51 will fit the upper end of the brake disc body 7 in advance. The first pressure rod 44 continues to move downward, so that the sliding block 51 presses the first spring 52 upward, so that the punching drill bit 513 fits the upper end of the brake disc body 7 with force under the tension of the first spring 52, and then the mounting block 56 slides upward on the outer side of the fixing rod 53 and cooperates with the limiting block 54 to press the second spring 55. The tension of the second spring 55 The force makes the punching drill 513 fit more closely to the upper end of the brake disc body 7, and the output shaft of the second motor 510 drives the connecting shaft 511 to rotate, and the connecting shaft 511 drives the punching drill 513 to rotate, so as to quickly punch the brake disc body 7. When punching, as the hole gradually goes deeper, the first spring 52 and the second spring 55 are gradually opened, and the tension makes the punching drill 513 continue to move downward, and the fixing plate 512 provides an installation space for the second motor 510. The fixing plate 512 cooperates with the two sets of L-shaped slides 59 to ensure the stability of the second motor 510 when moving.

[0030] In this embodiment, a first slide groove 57 is opened on the outer side of the mounting block 56 near the upper and lower ends, the lower end of the fixing plate 512 is fixedly connected to the oil tank 514, the connecting shaft 511 is rotatably connected to the inner side of the oil tank 514, and the inner side of the oil tank 514 outside the connecting shaft 511 is fixedly connected to the blade 515 through a sleeve.

[0031] Specifically, the first slide groove 57 provides an installation space for the oil tank 514 and limits the movement range of the oil tank 514. When the connecting shaft 511 rotates, it drives the blades 515 to stir the oil tank 514 to avoid the deposition of lubricating oil.

[0032] In this embodiment, a second electric telescopic rod 517 is installed on one side of the mounting block 56 , and the output shaft of the second electric telescopic rod 517 passes through the mounting block 56 , and the output shaft of the second electric telescopic rod 517 is fixedly connected to the oil tank 514 .

[0033] Specifically, the second electric telescopic rod 517 is started, and the output shaft of the second electric telescopic rod 517 drives the oil tank 514 to move in the first slide groove 57. The first slide groove 57 drives the second motor 510 to move synchronously through the fixed plate 512, and the L-shaped slide plate 59 slides in the second slide groove 58 to ensure the fixed position, so that the punching drill bit 513 is aligned with the next punching position.

[0034] In this embodiment, the outer side of the connecting shaft 511 is slidably connected with an isolating sleeve 518, and the inner wall of the isolating sleeve 518 is provided with a third sliding groove 519, and the third sliding groove 519 is designed with a slope height difference. The inner side of the third sliding groove 519 is slidably connected with a first sliding rod 520, and one end of the first sliding rod 520 is in contact with the inner wall of the third sliding groove 519, and the other end of the first sliding rod 520 is fixedly connected to the connecting shaft 511.

[0035] Specifically, the connecting shaft 511 drives the first slide bar 520 to rotate in the third slide groove 519. The height difference design of the third slide groove 519 enables the isolation sleeve 518 to move up and down, pressing the third spring 523 when moving upward. The tension of the third spring 523 assists the isolation sleeve 518 in resetting. When the isolation sleeve 518 moves upward, it offsets the isolation groove 521, allowing the lubricating oil in the oil tank 514 to enter the isolation groove 521.

[0036] In this embodiment, the outer side of the isolation sleeve 518 is slidably connected to the inner side of the isolation groove 521 near the lower end, the outer side of the isolation sleeve 518 fits with the inner wall of the isolation groove 521, and multiple groups of output holes 522 are opened on the inner side of the isolation groove 521. Multiple groups of oil delivery grooves 516 are opened on the outer side of the punching drill bit 513, and the output port of the output hole 522 is arranged inside the oil delivery groove 516.

[0037] Specifically, after the lubricating oil in the oil tank 514 enters the isolation groove 521, it is output to the oil delivery groove 516 through the output hole 522. After the isolation sleeve 518 is reset, it enters, presses and closes the isolation groove 521 to stop the output. The tension of the third spring 523 assists the isolation sleeve 518 in resetting.

[0038] In this embodiment, a second slide rod 524 is fixedly connected to the inner side of the punching drill bit 513, a grinding plate 525 is slidably connected to the outer side of the second slide rod 524, a fourth spring 526 is arranged on the outer side of the second slide rod 524, one end of the fourth spring 526 is fixedly connected to the punching drill bit 513, the other end of the fourth spring 526 is fixedly connected to the grinding plate 525, and the other side of the grinding plate 525 is designed as an arc surface.

[0039] Specifically, when the punching drill 513 punches downward step by step, the grinding sheet 525 will touch the heat dissipation hole and chamfer the heat dissipation hole under the rotation of the punching drill 513 to remove burrs. After the punching drill 513 continues to move downward, the grinding sheet 525 slides toward the inside of the punching drill 513 and then the second slide bar 524 slides into the inside of the grinding sheet 525 and presses the fourth spring 526. Then, the inside of the heat dissipation hole is cleaned to avoid missing burrs. After the grinding sheet 525 is offset from the heat dissipation hole, the grinding sheet 525 continues to chamfer the heat dissipation hole when the fourth spring 526 is opened. The arc surface design facilitates the grinding sheet 525 to enter the heat dissipation hole.

[0040] Working principle: when in use, the brake disc body 7 is installed on the upper end of the placement pile 6 to complete the placement, and the cylinder 3 is started. The output shaft of the cylinder 3 drives the first connecting plate 41 to move downward, and the first connecting plate 41 drives the first motor 42 to move, and the first motor 42 drives the second connecting plate 43 and the first pressure rod 44 to move downward, and the first pressure rod 44 drives the pressure plate 45 to enter the inner wall of the brake disc body 7 and then fit with the placement pile 6, and the first electric telescopic rod 48 installed inside the mounting plate 47 is started, so that the output shaft of the first electric telescopic rod 48 drives the card block 49 to enter the ventilation slot 8 to fix the position of the brake disc body 7. When the first pressure rod 44 moves downward, the sliding block 51 is driven downward by the tension of the first spring 52, and when the pressure plate 45 gradually approaches the placement pile 6, The sliding block 51 will fit the upper end of the brake disc body 7 in advance, and the first pressure rod 44 continues to move downward, so that the sliding block 51 presses the first spring 52 upward, so that the punching drill bit 513 fits the upper end of the brake disc body 7 with force under the tension of the first spring 52, and then the mounting block 56 slides upward on the outside of the fixing rod 53 and cooperates with the limiting block 54 to press the second spring 55. The tension of the second spring 55 makes the punching drill bit 513 fit more closely to the upper end of the brake disc body 7, and the second motor 510 is started. The output shaft of the second motor 510 drives the connecting shaft 511 to rotate, and the connecting shaft 511 drives the punching drill bit 513 to rotate, so as to quickly punch the brake disc body 7. When punching, as the hole goes deeper, the first spring 52 and the second spring 55 are pressed together. The spring 55 gradually expands, and the tension causes the punching drill bit 513 to continue to move downward. When punching, debris is generated on the inner side of the ventilation slot 8, and the compressed air is diverted to the telescopic air pipe 410 through the air distribution pipe 411. When the block 49 is connected to the ventilation slot 8, the air flow is output inside the ventilation slot 8, the debris is discharged outward, and the punching drill bit 513 is cooled. When the connecting shaft 511 rotates, it drives the blade 515 to stir in the oil tank 514 to prevent the lubricating oil from depositing. Then the connecting shaft 511 drives the first sliding rod 520 to rotate in the third sliding groove 519. The height difference design of the third sliding groove 519 makes the isolation sleeve 518 move up and down, and the third spring 523 is pressed when it moves upward. The tension of the third spring 523 assists the isolation sleeve 518 in resetting, isolating When the sleeve 518 moves upward, it staggers the isolation groove 521, so that the lubricating oil in the oil tank 514 enters the output hole 522 and is output to the oil delivery groove 516. After the isolation sleeve 518 is reset, it enters, presses and closes the isolation groove 521 to stop the output. The output lubricating oil lubricates the punching drill bit 513 from top to bottom and reduces the friction heat. When the punching drill bit 513 punches downward step by step, the grinding sheet 525 will touch the heat dissipation hole and chamfer the heat dissipation hole under the rotation of the punching drill bit 513 to remove burrs. After the punching drill bit 513 continues to move downward, the grinding sheet 525 slides into the inside of the punching drill bit 513 and then makes the second slide bar 524 slide into the inside of the grinding sheet 525, and presses the fourth spring 526, and then cleans the inside of the heat dissipation hole to avoid missing burrs.After the grinding sheet 525 is offset from the heat dissipation hole, the grinding sheet 525 continues to chamfer the heat dissipation hole when the fourth spring 526 is opened, and the debris in the heat dissipation hole is discharged outward through the ventilation slot 8 under the airflow output by the telescopic air pipe 410. After a set of punching is completed, the cylinder 3 is started to move upward, so that the positioning mechanism 4 and the punching mechanism 5 are offset from the brake disc body 7, and the first motor 42 is started. The output shaft of the first motor 42 drives the sliding block 51 to rotate a specified angle through the limit bar 46, so that the mounting block 56 always keeps horizontal alignment with a set of ventilation slots 8, so that the punching The mechanism 5 calibrates the position of the upper end of the next ventilation slot 8 within the same diameter, and then punches again. When the outermost punching of the brake disc body 7 is completed, the output shaft of the cylinder 3 is retracted first, and the second electric telescopic rod 517 is started. The output shaft of the second electric telescopic rod 517 drives the oil tank 514 to move in the first slide 57. The first slide 57 drives the second motor 510 to move synchronously through the fixing plate 512, and the L-shaped slide plate 59 slides in the second slide 58 to ensure the fixed position, so that the punching drill 513 is aligned with the next punching position.
