Description

Technical Field

[0001] The invention relates to the technical field of grinding devices, in particular to a grinding device for brake production. Background Art

[0002] The brake base plate is a vital component in the braking system. It provides a stable mounting base for other components of the brake, and its quality and performance directly affect the braking effect. Structurally, the brake base plate usually has high strength and good rigidity to withstand the huge forces generated during braking. It is precisely designed with specific positions and holes for installing parts such as brake shoes and brake wheel cylinders to ensure accurate fit between various components. From the material point of view, high-quality metal materials such as cast iron or special alloys are mostly used. These materials can not only withstand weight and pressure, but also resist wear and corrosion. During the operation of the brake, the base plate must remain stable. Any deformation or damage may cause problems such as brake failure or uneven wear, which seriously endangers driving safety. Therefore, the quality control and maintenance of the brake base plate are of great significance in the field of automotive safety.

[0003] The recycling and remanufacturing of brake base plates is an important environmental protection and resource utilization measure. During the recycling process, professionals will collect brake base plates from sources such as scrapped vehicles. These recycled base plates must undergo strict testing and evaluation before entering the remanufacturing stage to determine the degree of wear and cracks. Only after confirmation can the brake base plates enter the subsequent remanufacturing process. Before the remanufacturing process, the old brake base plates need to be polished to remove pollutants and oxide layers on their surface. However, the existing mechanical polishing method will generate large impact force and thermal stress during the treatment process. The impact force and thermal stress generated in this process will easily cause micro cracks on the surface of the brake during the polishing process, and residual stress is also likely to occur inside it, which will have a bad effect on the subsequent remanufacturing process. Therefore, technicians in this field have proposed a polishing device for brake production to solve the above-mentioned technical problems. Summary of the invention

[0013] Working principle: When remanufacturing the recovered brake base plates, the staff will first conduct strict inspection and evaluation on the recovered old brake base plates, and then remove the brake base plates that do not meet the remanufacturing conditions, and retain the brake base plates that can be remanufactured. After that, the positioning drive mechanism is started, and the staff will select the brake base plates that meet the remanufacturing conditions and place them in the positioning seat on the base, and use the positioning cavity in the positioning seat to position them before subsequent processing. After the positioning seat has positioned the brake base plate to be processed, the staff sends a control signal to the PLC controller on the top seat through the control device. After receiving the control signal, the PLC controller Afterwards, the rod body of the electric cylinder on the top seat is controlled to be pushed out, and the rod body of the electric cylinder drives the electromagnet seat at the bottom to move downward synchronously while being pushed out, and the electromagnet seat on the electric cylinder moves down to fit with the brake base plate in the positioning seat and stops moving. At this time, the electromagnet seat is energized and generates magnetism, so that the brake base plate in the positioning seat is adsorbed and fixed through the electromagnet seat. After that, the PLC controller controls the electric cylinder on the top seat to reset again. After the brake base plate in the positioning seat is adsorbed and fixed and reset through the electromagnet seat, the drive motor in the support tube is started at this time, and the shaft of the drive motor drives the connecting seat on it to rotate synchronously while rotating, and the connecting seat drives the upper support column on the limit rotating seat while rotating. And the support column rotates synchronously, and the support column also drives the top seat, electric cylinder, electromagnet seat and the brake base plate fixed thereon to move synchronously to the position of the second processing station while rotating, so as to complete the positioning and driving movement processing of the brake base plate; then the front-end processing mechanism is started, and the brake base plate fixed by the electromagnet seat has moved to the top of the container seat, and then the electromagnet seat rod body on the positioning drive mechanism is pushed out again, and the rod body on the electromagnet seat is pushed out while driving the brake base plate thereon to enter the dilute hydrochloric acid solution in the dissolving liquid chamber, and then the dilute hydrochloric acid solution is used to dissolve the rust and oxide layer on the surface of the brake base plate, thereby completing the brake base plate After preliminary treatment of the front end, the rod body of the electric cylinder on the top seat is reset, and while the rod body on the electric cylinder is reset, it drives the electromagnet seat and the brake base plate thereon to move up and reset synchronously. After the brake base plate is moved up and reset, the positioning drive mechanism drives it to move above the second container seat again, and then the rod body on the electric cylinder is pushed out again, so that the brake base plate on the electromagnet seat enters the cleaning liquid cavity in the second container seat. At this time, the ultrasonic generator on the second container seat is started and emits ultrasonic waves, so that the tiny bubbles in the cleaning liquid in the cleaning liquid cavity burst when they contact the surface of the base plate, generating a strong impact force, thereby removing impurities such as oil, dust, etc. on the surface of the base plate, thereby completing the re-treatment of the front end of the brake base plate;Then the adaptive grinding mechanism is started. First, the rod body on the electric cylinder is reset, while driving the electromagnet seat and the brake base plate on it to move up and reset synchronously. After the brake base plate is moved up and reset, the positioning drive mechanism drives it to move above the container seat three again, and then the rod body on the electric cylinder is pushed out again, so that the brake base plate on the electromagnet seat enters the grinding cavity in the container seat three, and then the electromagnet at the bottom of the rotating closing plate is energized and generates magnetism. When the electromagnet is energized to generate magnetism, the magnetic particle mixture on the upper part of the rotating closing plate is guided by the magnetic field to gather on the upper part of the electromagnet. At the same time, the shape of the magnetic particles gathered on the rotating closing plate is restricted by the upper brake base plate, so the rotating closing plate The magnetic particle clusters gathered on the upper part of the closing plate contact the bottom of the brake base plate, and then the driving motor in the container seat three is driven, and the rotating shaft of the driving motor drives the rotating closing plate in the sealing groove to rotate synchronously while rotating, and the rotating closing plate drives the electromagnet at its bottom to rotate synchronously while rotating, and the electromagnet guides the magnetic particle clusters gathered on the upper part of the rotating closing plate to rotate synchronously while rotating, and the magnetic particle clusters grind the brake base plate while rotating, and at the same time, the output voltage is adjusted by the current regulator to accurately control the current passing through the electromagnet, thereby realizing precise adjustment of the magnetic field strength, and at the same time, the current sensor can also monitor the current value in real time to ensure the stability of the magnetic field strength. and accuracy, thereby ensuring the grinding effect of the magnetic particle group on the brake base plate, thereby completing the adaptive grinding treatment of the brake base plate; then the rear-end auxiliary mechanism is started, and after the adaptive grinding mechanism has completed the grinding of the brake base plate, the rod body on the electric cylinder is reset while driving the electromagnet seat and the brake base plate thereon to move up and reset synchronously, and then after the brake base plate is moved up and reset, the positioning drive mechanism drives it to move to the top of the container seat four again, and then the rod body on the electric cylinder is pushed out again, so that the brake base plate on the electromagnet seat enters into the passivation liquid chamber in the container seat four, and then the brake base plate entering the passivation liquid chamber contacts the passivation liquid inside it, so that the passivation liquid is in A passivation film is formed on the surface of the brake base plate, thereby completing the passivation protection treatment of the brake base plate after grinding. Then, the rod body on the electric cylinder is reset while driving the electromagnet seat on it and the processed brake base plate to move up and reset synchronously. After the brake base plate is moved up and reset, the positioning drive mechanism drives it to move above the placement seat again, and then the rod body on the electric cylinder is pushed out again, so that the brake base plate on the electromagnet seat enters the placement cavity of the placement seat. After that, the electromagnet seat is reset after power is cut off. The staff can take out the brake base plate in the placement seat after the treatment is completed and send it to the subsequent painting station or directly collect it for processing, so as to complete the rear end auxiliary shaping treatment of the brake base plate. ;

[0014] The present invention provides a grinding device for brake production, which has the following beneficial effects: 1. The present invention adds and sets a positioning drive mechanism. When the old brake base plate is remanufactured, the mechanism can, on the one hand, position and fix the brake base plate, thereby ensuring its stability in the subsequent processing process and also ensuring the precise implementation of each subsequent process. On the other hand, the mechanism can also drive the fixed brake base plate to circulate and move between various processing stations, thereby reducing the tediousness and potential damage of manual handling, improving the remanufacturing efficiency, making the entire remanufacturing process smoother and more efficient, and ensuring product quality.

[0015] 2. The present invention adds and sets a pretreatment mechanism, and pretreats the recovered old brake base plate in turn by chemical and ultrasonic methods before grinding. Not only can the rust and oxide layer on the surface of the old brake base plate be removed by chemical reaction, so that the magnetic material can better contact the real surface of the brake base plate during the subsequent grinding treatment, thereby improving the grinding quality of the brake base plate and reducing the wear of the magnetic material. In addition, the brake base plate is treated again by ultrasonic method, and the cavitation effect generated by ultrasonic waves in the cleaning fluid is utilized to make the tiny bubbles in the cleaning fluid burst when contacting the base plate surface, generating a strong impact force, thereby removing impurities such as oil, dust, etc. on the base plate surface, providing a clean surface for the subsequent grinding of the magnetic material, and improving the adsorption effect and grinding uniformity between the magnetic material and the base plate.

[0016] 3. The present invention increases and sets a magnetic grinding mechanism. When grinding the brake base plate after pretreatment, firstly, the shape and stiffness of the grinding layer formed by the magnetic particles through magnetic pole control can be adaptively adjusted according to the change of the magnetic field. When the surface shape of the base plate is irregular or there are local depressions or protrusions, the magnetic abrasive can automatically adhere to the surface for grinding, ensuring that the entire surface can be effectively processed. This adaptability is very beneficial for the grinding of brake base plates with complex shapes, and improves the grinding quality and efficiency of the brake base plates. Secondly, the mechanism achieves precise control of the grinding force by precisely controlling the strength and direction of the magnetic field. This precise grinding force control helps to ensure the grinding effect while avoiding excessive grinding or damage to the base plate surface.

[0017] 4. The present invention increases and sets a magnetic grinding mechanism. When grinding the brake base plate after pretreatment, the magnetic abrasive grinding process is relatively gentle and will not generate large impact force and thermal stress like some traditional mechanical grinding methods. This helps to maintain the integrity of the brake base plate surface and reduce the generation of micro cracks and residual stress, thereby improving the mechanical properties and service life of the base plate. At the same time, the magnetic abrasive can be recovered through the magnetic field after the grinding process is completed, and can be reused after screening and processing. This treatment method not only reduces the abrasive cost, but also reduces the generation of waste.

[0018] 5. The present invention, by adding and setting a rear-end auxiliary mechanism, passivates the brake base plate after being processed by the magnetic grinding mechanism, which can not only enhance the corrosion resistance of the brake base plate, thereby facilitating subsequent reuse and storage, but also the protective layer on the surface of the brake base plate may be damaged after grinding, and the passivation treatment can repair and strengthen the protection in time, thereby extending the service life of the brake base plate. At the same time, the passivation film formed can also prevent the surface of the base plate from being oxidized and contaminated during storage and use, thereby maintaining the stable performance of the base plate.

[0021] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] When the positioning drive mechanism is started, the staff will select the brake base plate that meets the remanufacturing conditions and place it in the positioning seat 4 on the base 1, and perform positioning processing on it before subsequent processing through the positioning cavity in the positioning seat 4.

[0024] Then, after the positioning seat 4 has positioned the brake base plate to be processed, the staff sends a control signal to the PLC controller 9 on the top seat 13 through the control device. After receiving the control signal, the PLC controller 9 controls the rod body of the electric cylinder 21 on the top seat 13 to be pushed out. While the rod body of the electric cylinder 21 is pushed out, it drives the electromagnet seat 7 at the bottom to move downward synchronously. After the electromagnet seat 7 on the electric cylinder 21 moves down to fit the brake base plate in the positioning seat 4, it stops moving. At this time, the electromagnet seat 7 is energized and generates magnetism, so that the brake base plate in the positioning seat 4 is adsorbed and fixed by the electromagnet seat 7. Then the PLC controller 9 controls the electric cylinder 21 on the top seat 13 to reset again.

[0025] The positioning drive mechanism also includes a connecting seat 24, the bottom end of the support column 16 is fixedly connected to the connecting seat 24, a driving motor 25 is arranged in the middle of the inner bottom end of the support tube 3, and the output end of the driving motor 25 is connected to the middle of the bottom end of the connecting seat 24, the middle of the top end of the support column 16 is fixedly connected to the top seat 13, the middle of the top end of the top seat 13 is arranged with a PLC controller 9, an electric cylinder 21 is arranged on one side of the middle of the bottom end of the top seat 13 near the edge, an electromagnet seat 7 is arranged at the bottom of the electric cylinder 21, and the top end of the rod body of the electric cylinder 21 is fixedly connected to the middle of the top end of the electromagnet seat 7.

[0026] After the brake base plate in the positioning seat 4 is adsorbed, fixed and reset by the electromagnet seat 7, the drive motor 25 in the support cylinder 3 is started, and the rotating shaft of the drive motor 25 drives the connecting seat 24 thereon to rotate synchronously while rotating. The connecting seat 24 drives the support column 16 on its upper part to rotate synchronously within the limited rotating seat 23 and the support column 16 while rotating, and the support column 16 also drives the top seat 13, the electric cylinder 21, the electromagnet seat 7 and the brake base plate fixed thereon to move synchronously to the position of the second processing station 12 while rotating, thereby completing the positioning of the brake base plate and driving the movement processing.

[0027] Please see attached Figure 6 , a front-end processing mechanism, which is arranged on the second processing station 12 and the third processing station 12 on the base 1, and is used for performing front-end processing operations on the brake base plate after the positioning drive mechanism is processed before remanufacturing and grinding; The front-end processing mechanism includes a container seat 6, and the container seat 6 is fixedly connected to the second processing station 12. A dissolving liquid chamber 22 is opened inside the container seat 6, and a dilute hydrochloric acid solution is arranged in the dissolving liquid chamber 22.

[0028] When the front-end processing mechanism is started, the brake base plate fixed by the electromagnet seat 7 has moved to the top of the container seat 6, and then the rod body of the electromagnet seat 7 on the positioning drive mechanism is pushed out again. While the rod body on the electromagnet seat 7 is pushed out, it drives the brake base plate thereon into the dilute hydrochloric acid solution in the dissolving liquid chamber 22, and then the rust and oxide layer on the surface of the brake base plate are dissolved by the dilute hydrochloric acid solution, thereby completing the preliminary processing of the front end of the brake base plate.

[0029] The front-end processing mechanism also includes a container seat 2 8, and the container seat 2 8 is fixedly connected to the third processing station 12. A cleaning liquid cavity 17 is opened inside the container seat 2 8, and a cleaning liquid 26 is arranged inside the cleaning liquid cavity 17. An ultrasonic generator 15 is fixedly connected to the middle of the outer wall of the container seat 2 8.

[0030] Then the rod body of the electric cylinder 21 on the top seat 13 is reset, and while the rod body on the electric cylinder 21 is reset, it drives the electromagnet seat 7 and the brake base plate thereon to move up and reset synchronously. After the brake base plate is moved up and reset, the positioning drive mechanism drives it to move above the container seat 8 again, and then the rod body on the electric cylinder 21 is pushed out again, so that the brake base plate on the electromagnet seat 7 enters the cleaning liquid cavity 17 in the container seat 8. At this time, the ultrasonic generator 15 on the container seat 8 is started and emits ultrasonic waves, so that the tiny bubbles in the cleaning liquid in the cleaning liquid cavity 17 burst when they contact the surface of the base plate, generating a strong impact force, thereby removing impurities such as oil, dust and the like on the surface of the base plate, thereby completing the re-processing of the front end of the brake base plate.

[0031] Please see attached Figure 7 - Attachment Figure 8 , an adaptive grinding mechanism, which is arranged on the fourth processing station 12 on the base 1, and is used to perform adaptive grinding processing on the brake base plate after being processed by the front-end processing mechanism; The adaptive grinding mechanism includes a container seat three 10, and the container seat three 10 is fixedly connected to the fourth processing station 12. A grinding chamber 30 is opened inside the container seat three 10, and a sealing groove 28 is opened in the middle and lower part of the inner wall of the grinding chamber 30. A rotating closing plate 18 is rotatably connected in the sealing groove 28, and a magnetic particle mixture 27 is arranged on the upper part of the rotating closing plate 18.

[0032] When grinding the product, it is necessary to select suitable magnetic particles, such as tiny particles and abrasive particles made of magnetic materials such as iron, cobalt, and nickel. According to the material and grinding requirements of the brake base plate, abrasive particles of different hardness and particle size such as aluminum oxide and silicon carbide can be selected and mixed in a certain proportion to form magnetic abrasives. For brake base plates with higher hardness, the proportion of silicon carbide abrasive particles can be appropriately increased, and abrasive particles with coarser particle size can be selected for the rough grinding stage, and water is used to increase its fluidity to form a magnetic particle mixture 27, so that the grinding process is smoother.

[0033] When the adaptive grinding mechanism is started, the rod body on the electric cylinder 21 is first reset, while driving the electromagnet seat 7 and the brake base plate thereon to move up and reset synchronously. After the brake base plate is moved up and reset, the positioning drive mechanism drives it to move above the container seat three 10 again, and then the rod body on the electric cylinder 21 is pushed out again, so that the brake base plate on the electromagnet seat 7 enters the grinding chamber 30 in the container seat three 10.

[0034] The adaptive grinding mechanism also includes a driving motor 29, which is arranged at the middle of the inner bottom end of the container seat 3 10, and the output end of the driving motor 29 is connected to the middle of the rotating closing plate 18, and a plurality of electromagnets 32 are arranged in a circular array around the middle of the bottom end of the rotating closing plate 18, a current sensor 31 is arranged on one side of the middle of the bottom end of the rotating closing plate 18, and a current regulator 33 is arranged on the other side of the middle of the bottom end of the rotating closing plate 18.

[0035] Then, the electromagnet 32 ​​at the bottom of the rotating closing plate 18 is energized to generate magnetism. When the electromagnet 32 ​​is energized to generate magnetism, the magnetic particle mixture 27 at the upper part of the rotating closing plate 18 is guided by the magnetic field to gather at the upper part of the electromagnet 32. At the same time, the shape of the magnetic particles gathered on the rotating closing plate 18 is restricted by the upper brake bottom plate, so the magnetic particle clusters gathered on the upper part of the rotating closing plate 18 are in contact with the bottom of the brake bottom plate, and then the driving motor 29 in the container seat three 10 is driven.

[0036] The rotating shaft of the driving motor 29 drives the rotating sealing plate 18 in the sealing groove 28 to rotate synchronously while rotating. The rotating sealing plate 18 drives the electromagnet 32 ​​at the bottom thereof to rotate synchronously while rotating. The electromagnet 32 ​​guides the magnetic particle cluster gathered on the upper part of the rotating sealing plate 18 to rotate synchronously while rotating. The magnetic particle cluster grinds the brake base plate while rotating, and at the same time, the output voltage is adjusted by the current regulator 33 to accurately control the current passing through the electromagnet 32, thereby realizing precise adjustment of the magnetic field strength. At the same time, the current sensor 31 can also monitor the current value in real time to ensure the stability and accuracy of the magnetic field strength, thereby ensuring the grinding effect of the magnetic particle cluster on the brake base plate, thereby completing the adaptive grinding treatment of the brake base plate.

[0037] The 32-pole electromagnet can precisely control the magnetic field strength and direction by adjusting the current, which is suitable for complex grinding tasks that require dynamic adjustment of the magnetic field. The shape of the pole can be round, square or other special shapes to meet the grinding needs of brake base plates of different shapes and sizes.

[0038] The rear-end auxiliary mechanism is arranged on the fifth processing station 12 and the sixth processing station 12 on the base 1, and is used for performing auxiliary shaping processing on the brake base plate after being processed by the adaptive grinding mechanism.

[0039] The rear-end auxiliary mechanism includes a container seat four 11, and the container seat four 11 is fixedly connected to the fifth processing station 12. A passivation liquid chamber 20 is opened inside the container seat four 11, and a passivation liquid is arranged inside the passivation liquid chamber 20. A plurality of drainage pipes 14 are arranged in a circular array in the middle part of the outer wall of the base 1, and the drainage pipes 14 are respectively connected to the interior of the container seat at the corresponding position, and a placement seat 2 is fixedly connected to the sixth processing station 12.

[0040] When the rear-end auxiliary mechanism is started, after the adaptive grinding mechanism completes grinding of the brake base plate, the rod body on the electric cylinder 21 is reset while driving the electromagnet seat 7 and the brake base plate thereon to move up and reset synchronously. After the brake base plate is moved up and reset, the positioning drive mechanism drives it to move above the container seat four 11 again, and then the rod body on the electric cylinder 21 is pushed out again, so that the brake base plate on the electromagnet seat 7 enters into the passivation liquid chamber 20 in the container seat four 11, and then the brake base plate entering the passivation liquid chamber 20 contacts with the passivation liquid inside it, so that the passivation liquid forms a passivation film on the surface of the brake base plate, thereby completing the passivation protection treatment of the brake base plate after grinding.

[0041] Then the rod body on the electric cylinder 21 is reset while driving the electromagnet seat 7 thereon and the processed brake base plate to move up and reset synchronously. After the brake base plate is moved up and reset, the positioning drive mechanism drives it to move to the top of the placement seat 2 again, and then the rod body on the electric cylinder 21 is pushed out again, so that the brake base plate on the electromagnet seat 7 enters the placement cavity of the placement seat 2. After that, the electromagnet seat 7 is reset after power is cut off, and the staff can take out the brake base plate in the placement seat 2 that has been processed, and send it to the subsequent painting station or directly collect it for processing, so as to complete the rear end auxiliary shaping processing of the brake base plate.
