Description

Technical Field

[0001] The invention belongs to the technical field of friction plate processing, and in particular relates to a clamping tool for processing a brake friction plate. Background Art

[0002] In order to ensure the surface quality and performance of the friction plate, it is usually necessary to grind the surface of the friction plate during processing. The grinding process can remove burrs, uneven parts, and possible oxide layers on the surface, thereby improving the surface finish and friction coefficient of the friction plate, ensuring its performance stability and safety in actual applications.

[0003] The friction plate needs to be fixed with a clamping fixture during grinding. There are many types of friction plate clamping fixtures on the market, such as a fixing fixture for friction plate detection with application number: CN202223147383.4. When in use, the friction plate is placed on the arc-shaped supporting seat, and the electric push rod is controlled to extend to drive the clamping block to move downward. The friction plate can be automatically clamped and fixed by the arc-shaped supporting seat and the clamping block to achieve automatic and rapid clamping. When in use, the arc-shaped supporting seat is driven to move by controlling the extension of the electric telescopic rod, and the range of the arc-shaped supporting seat extending from the front surface of the vertical end of the L-shaped fixture seat is adjusted, thereby achieving the range of the arc-shaped supporting seat supporting the friction plate, so that the friction plate will not be clamped and fixed in a full-coverage manner, which is convenient for the detection of the friction plate. Furthermore, an arc-shaped reinforcement plate is provided to provide auxiliary support for the arc-shaped supporting seat to improve its strength.

[0004] However, in the actual application process, there are still some problems that need to be solved. First, after the friction plate is fixed, it will cause a certain degree of obstruction on the surface, which will directly affect the subsequent processing process. Secondly, during the processing, the friction plate cannot be effectively cooled, which may cause the friction plate to overheat, thus affecting its service life and processing effect. In addition, the debris generated during the processing cannot be effectively collected. If these debris are not cleaned up in time, they may cause damage to the equipment and even affect the smooth progress of the entire processing process. Summary of the invention

[0047] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0048] Please see attached Figures 1 to 9 As shown, this embodiment provides a clamping tool for processing brake friction pads, including a dust hood 1, the inner ring of the dust hood 1 is fixedly connected to a water storage tank 2 by a support rod, the upper end of the water storage tank 2 is rotatably connected to a turntable 3, and a filter screen is installed inside the dust hood 1, and the filter screen is annular and inclined toward the dust box 5;

[0049] The clamping mechanism 4 is disposed on the turntable 3. The clamping mechanism 4 includes a clamping portion 41 and a control portion 42. The clamping portion 41 is used to clamp the friction plate to be processed, and the control portion 42 is used to control the operation of the clamping portion 41.

[0050] A dust box 5 is sleeved on the outside of the dust hood 1 and is in communication with the dust hood 1. A base 6 is fixedly connected to the lower end of the dust box 5. An air inlet groove is provided at the lower end of the base 6 for air circulation (not shown in the figure);

[0051] An auxiliary mechanism 7, the auxiliary mechanism 7 is arranged inside the base 6;

[0052] Among them, the auxiliary mechanism 7 includes a driving part 71, which is fixedly installed in the base 6. The inner wall of the water storage tank 2 is fixedly connected with a first hollow cylinder 72 in a ring-shaped distribution by using a support rod. A lifting part 73 is provided at the lower end of the first hollow cylinder 72, and a water delivery part 74 is provided at the upper end of the first hollow cylinder 72. A negative pressure part 75 is provided at the lower end of the dust hood 1, and a cleaning part 76 is provided inside the dust hood 1.

[0053] In this embodiment, the driving part 71 is connected to the turntable 3 through a transmission rod to ensure that the driving part 71 can drive the turntable 3 to rotate when driven, thereby prompting the lifting part 73 in the first hollow cylinder 72 to perform corresponding lifting and lowering movements. The water supply part 74 is responsible for conveying the water source or coolant in the water tank 2 to the clamping mechanism 4 to dissipate heat from the clamped friction plate. The negative pressure part 75 is connected to the interior of the dust hood 1 to form a negative pressure environment to enhance the dust collection effect and ensure that the dust generated during the processing is effectively collected. The cleaning part 76 is responsible for regularly cleaning the dust accumulated on the filter screen to ensure the cleanliness and work efficiency of the dust hood 1. Through such a design, the clamping tooling for brake friction pad processing can achieve an efficient and clean friction pad processing process;

[0054] It should be added that a water filling pipe is provided on the turntable 3 so as to add water or coolant into the water storage tank 2 .

[0055] Next, please refer to Figure 2 and Figure 5 The clamping portion 41 includes a lower clamping block 411, which is fixedly connected to the top surface of the turntable 3, and a guide rod 412 is fixedly connected to the top surface of the turntable 3, and the guide rod 412 is located on one side of the lower clamping block 411, and an upper clamping block 413 is slidably connected to the guide rod 412, and a first compression spring 414 is sleeved on the upper end of the guide rod 412, a telescopic hose 415 is connected between the upper clamping block 413 and the lower clamping block 411, and a drain pipe 416 is connected to the lower clamping block 411.

[0056] Secondly, please also refer to Figure 5 and Figure 6The control unit 42 includes a second hollow cylinder 421, which is fixedly connected to the turntable 3 by a support rod. An electric push rod 422 is installed on the turntable 3, and the telescopic end of the electric push rod 422 is piston-type inserted in the second hollow cylinder 421, and the telescopic end of the electric push rod 422 is connected to the first piston plate 423, a support plate is fixedly connected to the guide rod 412, and a third hollow cylinder 424 is connected to the support plate, and a first piston rod 425 is inserted at the lower end of the third hollow cylinder 424, one end of the first piston rod 425 is connected to the second piston plate 426, and the other end of the first piston rod 425 is connected to a pressure block 427, and the outer sleeve of the first piston rod 425 is provided with a second compression spring 428, and a liquid guide tube 429 is connected to the third hollow cylinder 424, and the other end of the liquid guide tube 429 is connected to the second hollow cylinder 421.

[0057] In this embodiment, the upper clamp block 413 is pulled upward along the guide rod 412 to compress the first compression spring 414. Subsequently, the friction plate is placed on the lower clamp block 411 and the upper clamp block 413 is released. Under the reset force of the first compression spring 414, the upper clamp block 413 moves downward to clamp the friction plate, thereby achieving preliminary fixation. The fixing process is completed by the cooperation of the upper clamp block 413 and the lower clamp block 411, and the outer side of the friction plate is not blocked, which is convenient for grinding and testing the outer side. Hydraulic oil is injected into the second hollow cylinder 421, and the first piston plate 423 is moved upward along the second hollow cylinder 421 by controlling the extension of the electric push rod 422 to squeeze the internal hydraulic oil. The squeezed hydraulic oil flows into the third hollow cylinder 424 through the liquid guide tube 429, and the hydraulic oil pushes the second piston plate 426, the first piston rod 425 and the compression block 427 downward in the third hollow cylinder 424, and compresses the second compression spring 428. The upper clamping block 413 is pressed by the pressing block 427 to move it downwards, thereby completing the final fixation and preventing the friction plate from shaking during the processing, thereby improving the stability of the processing.

[0058] Next, please refer to Figure 7 The driving part 71 includes a motor 711, which is installed on the bottom surface of the inner cavity of the base 6. The upper end of the output shaft of the motor 711 is fixedly connected to a driving rod 712, which extends into the water tank 2 and is fixedly connected to the turntable 3. A disc 713 is fixedly connected to the driving rod 712, a protrusion 714 is fixedly connected to the disc 713, and a large gear 715 is also fixedly connected to the driving rod 712.

[0059] In this embodiment, water or coolant is injected into the water tank 2. During the processing, the motor 711 is started to drive the driving rod 712 to rotate, thereby rotating the disc 713, the large gear 715 and the rotating disc 3. The rotation of the rotating disc 3 drives the friction plate to perform continuous grinding operations.

[0060] Please refer again Figure 8 The lifting part 73 includes a hollow rod 731, which is slidably inserted into the lower end of the first hollow cylinder 72. Through holes 732 are evenly distributed on the hollow rod 731. The upper end of the hollow rod 731 is fixedly connected to a third piston plate 733, and a stopper 734 is provided on the third piston plate 733. A spring 735 is connected between the stopper 734 and the third piston plate 733. The outer part of the hollow rod 731 is sleeved with a third compression spring 736. The lower end of the hollow rod 731 is fixedly connected to a mounting seat 737, and a roller 738 is rotatably connected to the mounting seat 737.

[0061] Please refer again Figure 5 and Figure 5 The water delivery part 74 includes a first annular groove 741 and a second annular groove 742. The first annular groove 741 and the second annular groove 742 are both opened on the turntable 3. The lower end of the first annular groove 741 is rotatably connected to an annular water storage pipe 743. The first annular groove 741 is connected to a water inlet pipe 744, and the water inlet pipe 744 is connected to the upper clamping block 413. The first hollow cylinder 72 is connected to a water delivery pipe 745, and the upper end of the water delivery pipe 745 is connected to the annular water storage pipe 743. A one-way valve 746 is arranged on the water delivery pipe 745.

[0062] In this embodiment, the rotation of the disc 713 drives the protrusion 714 to rotate accordingly. When the protrusion 714 moves to the lower end of the hollow rod 731, it will contact the roller 738, causing the hollow rod 731 to move upward. The rise of the hollow rod 731 drives the third piston plate 733 to move upward, thereby squeezing the liquid in the first hollow cylinder 72 (at this time, due to inertia, the stopper 734 will fit tightly with the third piston plate 733, preventing the liquid from flowing out through the hollow rod 731). The liquid is therefore pushed into the water pipe 745 and enters the annular water storage pipe 743; a one-way valve 746 is provided on the water pipe 745, which only allows the liquid to flow from the first hollow cylinder 72 into the annular water storage pipe 743 to prevent the liquid from flowing back. The liquid pushed into the annular water storage pipe 743 enters the first annular groove 741, then enters the upper clamping block 413 through the water inlet pipe 744, then enters the lower clamping block 411 through the telescopic hose 415, and finally flows into the second annular groove 742 through the drain pipe 416, and flows into the water storage tank 2 through the water outlet hole at the lower end of the second annular groove 742. The friction plates fixed on the upper clamping block 413 and the lower clamping block 411 can be cooled by the circulating water source or coolant, effectively reducing the temperature of the friction plates during the processing and extending their service life.

[0063] When the protrusion 714 is no longer in contact with the roller 738, the hollow rod 731 rapidly descends under the action of the restoring force of the third compression spring 736. At this time, due to the effect of inertia, the stopper 734 will separate from the third piston plate 733, and the liquid will enter the hollow rod 731 through the through hole 732, and flow into the first hollow cylinder 72 through the gap between the stopper 734 and the third piston plate 733. The rapid descent of the third piston plate 733 will generate negative pressure at the upper end of the first hollow cylinder 72, prompting the liquid to be quickly sucked in.

[0064] It should be noted that the one-way valve 746 adopts the products currently available on the market. When selecting the model, it should be selected as much as possible to meet the requirements of this application under the premise of suitable specifications and usage scenarios. The specific model specifications are not limited here.

[0065] Please refer again Figure 3 and Fig. 9 The negative pressure part 75 includes a ventilation hood 751, which is connected to the lower end of the dust collection hood 1. A round rod 752 is rotatably connected to the ventilation hood 751, and a fan blade 753 and a small gear 754 are installed on the round rod 752.

[0066] In this embodiment, the large gear 715 is meshed with the small gear 754. When the large gear 715 rotates, it drives the small gear 754 to rotate accordingly. Since the diameter of the small gear 754 is small, a speed difference is generated, which in turn causes the round rod 752 to rotate rapidly. The rotation of the round rod 752 drives the fan blade 753 to rotate, thereby generating suction inside the ventilation hood 751. The suction forms a negative pressure inside the dust hood 1, sucking in the debris generated during the processing.

[0067] Please refer again Figure 5 The cleaning portion 76 includes an annular slider 761, which is rotatably connected to the dust hood 1. The inner ring of the annular slider 761 is connected to a connecting rod 762 in an annular shape, and the other end of the connecting rod 762 is connected to the turntable 3. The outer ring of the annular slider 761 is connected to a scraper 763 in an annular shape.

[0068] In this embodiment, the rotating disk 3 drives the annular slider 761 to rotate during the rotation process, and the rotation of the annular slider 761 drives the scraper 763 to rotate. During the rotation process, the scraper 763 uses the centrifugal force generated by its movement to remove the dust on the filter to prevent the filter from being blocked. At the same time, the scraper 763 throws the dust on the filter into the dust box 5. The dust box 5 is equipped with a sealed door to facilitate the cleaning of the collected dust.

[0069] The working principle of the present invention is:

[0070] Clamping mechanism

[0071] Preliminary fixation: manually pull the upper clamp block 413 to move upward along the guide rod 412 and compress the first compression spring 414, then place the friction plate on the lower clamp block 411. After loosening the upper clamp block 413, the upper clamp block 413 moves downward under the restoring force of the first compression spring 414 to preliminarily fix the friction plate.

[0072] Final fixation: By controlling the extension of the electric push rod 422, the first piston plate 423 is driven to move upward along the second hollow cylinder 421 to squeeze the hydraulic oil inside. The hydraulic oil enters the third hollow cylinder 424 through the liquid guide tube 429, pushing the second piston plate 426, the first piston rod 425 and the pressure block 427 to move downward, further pressing the upper clamping block 413, completing the final fixation and ensuring that the friction plate will not shake during the processing.

[0073] Cooling mechanism

[0074] Coolant circulation: water or coolant is injected into the water storage tank 2. The motor 711 is started to drive the driving rod 712 to rotate, and the disc 713 on the driving rod 712 rotates with it. The protrusion 714 on the disc 713 periodically contacts the roller 738, so that the hollow rod 731 moves up and down. When the protrusion 714 contacts the roller 738, the hollow rod 731 rises, and the third piston plate 733 squeezes the liquid in the first hollow cylinder 72, and enters the annular water storage pipe 743 through the water delivery pipe 745, and then enters the upper clamping block 413 through the water inlet pipe 744, and enters the lower clamping block 411 through the telescopic hose 415, and finally flows into the second annular groove 742 through the drain pipe 416, and flows back to the water storage tank 2 through the water outlet hole at its lower end, forming a coolant circulation.

[0075] Cooling effect: Through the above-mentioned coolant circulation system, the friction plates fixed on the upper clamping block 413 and the lower clamping block 411 can be continuously cooled, thereby effectively reducing the temperature of the friction plates during the processing and extending their service life.

[0076] Vacuuming mechanism

[0077] Negative pressure generation: The large gear 715 is meshed with the small gear 754. When the large gear 715 rotates, it drives the small gear 754 to rotate at a high speed, thereby causing the fan blades 753 on the round rod 752 to rotate quickly, generating suction inside the ventilation hood 751, forming a negative pressure environment.

[0078] Debris collection: The negative pressure environment generates suction inside the dust hood 1, which sucks the debris generated during the processing into the dust hood 1, and after being filtered through the filter, the clean air is discharged, and the debris is collected in the dust box 5.

[0079] Cleaning mechanism

[0080] Filter cleaning: The rotating disk 3 drives the annular slider 761 to rotate during the rotation process, and the scraper 763 on the annular slider 761 rotates accordingly. During the rotation process, the scraper 763 uses centrifugal force to remove dust on the filter and throw it into the dust collection box 5 to avoid clogging of the filter and maintain the efficient operation of the dust collection system.

[0081] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
