Description

Technical Field

[0001] This utility model relates to the field of brake disc surface treatment technology, specifically a rust prevention device for automotive brake disc surface treatment. Background Technology

[0002] With the rapid development of China's automotive industry, the number of cars in the country has grown rapidly, and vehicles have become an indispensable means of transportation in modern life. The braking system, as one of the most critical automotive components, directly affects people's travel safety. The brake disc is a key component of the automotive braking system, assembled with the wheel hub. Through dry friction with the brake pads, it generates enormous frictional force, reducing wheel speed and thus slowing down the vehicle.

[0003] To prevent brake discs from rusting, existing processing methods often involve coating the brake pads and sintering the coating to form a protective layer. This process typically requires a high-temperature sintering furnace to sinter the brake pads. However, the air inside a typical high-temperature sintering furnace expands when heated, resulting in higher internal pressure than external pressure. If the furnace is opened directly before it has fully cooled down, the furnace may eject high-temperature air that could burn people.

[0004] Therefore, those skilled in the art have proposed a rust-preventive device for the surface treatment of automotive brake discs to solve the problems mentioned in the background above. Utility Model Content

[0005] The purpose of this invention is to provide a rust-preventive device for surface treatment of automotive brake discs, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rust-preventive device for surface treatment of automotive brake discs includes a heating chamber containing multiple sets of electric heating rods fixedly installed inside, and further includes:

[0008] Multiple holding mechanisms are installed inside the heating box. Each holding mechanism includes multiple fixed frames that are fixedly connected to the heating box, and a support frame is movably installed on each fixed frame.

[0009] A movable frame structure installed inside a heating chamber, the movable frame structure including a lifting frame part installed inside the heating chamber, the lifting frame part being connected to a grab frame part;

[0011] A negative pressure gas storage structure connected to the heating box.

[0012] As a further improvement of this utility model: the lifting frame includes two sets of tracks fixedly connected to the heating box, the tracks are slidably connected to a lifting frame, the lifting frame is fixedly connected to two sets of symmetrically arranged second double-output shaft motors, the output ends of the second double-output shaft motors are fixedly connected to gears, the gears are meshed with a rack fixedly connected to the heating box, a first motor is fixedly installed in the middle of the lifting frame, the output shaft of the first motor is fixedly connected to a rotating frame, the rotating frame is hinged to two sets of connecting frames, the connecting frames are hinged to a linkage frame slidably connected to the lifting frame, and the linkage frame is connected to the grab frame.

[0013] As a further improvement of this utility model: the grabbing frame includes a guide frame fixedly connected to the linkage frame, a second motor is fixedly connected to the guide frame, a lead screw is fixedly connected to the output shaft of the second motor, a slider is threadedly connected to the lead screw and slidably connected to the guide frame, and a clamp is fixedly connected to the slider.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In use, a support frame carries the brake disc to be processed, and an electric heating rod heats the surface coating of the brake disc for sintering and curing. When the processed brake disc needs to be removed, the lifting support frame moves the grabbing frame, which in turn moves the support frame onto the lifting support frame. The lifting support frame then lifts the support frame, causing it to move towards the rectangular cover. The negative pressure air storage structure draws air to reduce the air pressure inside the heating chamber. After the rectangular cover is aligned with the lifting support frame, the first dual-shaft motor drives the cover plate to rotate. Personnel remove the support frame from the lifting support frame to obtain the processed brake disc. The support frame containing the brake disc to be processed is then placed on the lifting support frame. The first dual-shaft motor drives the cover plate to close the opening at the top of the rectangular cover. The lifting support frame then descends, and the grabbing frame moves the support frame onto a set of fixed frames. This utility model, through the cooperation of the holding mechanism, the moving frame structure, the isolation discharge structure, and the negative pressure air storage structure, facilitates the removal of the processed brake disc by personnel when the heating box is under negative pressure, thus avoiding burns to personnel from the hot air ejected from the heating box and protecting personnel safety.

Detailed Implementation

[0025] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0026] Example 1, see Figures 1-6 As shown, a rust-preventing device for automotive brake disc surface treatment includes a heating box 1, a control console fixedly connected to the heating box 1, and multiple sets of electric heating rods 2 fixedly installed inside the heating box 1. It also includes:

[0027] Multiple holding mechanisms 3 are installed inside the heating box 1. Each holding mechanism 3 includes multiple fixed frames 4 that are fixedly connected to the heating box 1. A support frame 5 is movably installed on the fixed frame 4.

[0028] A movable frame structure 6 is installed inside the heating box 1. The movable frame structure 6 includes a lifting frame part 7 installed inside the heating box 1. The lifting frame part 7 is connected to a grab frame part 8.

[0029] An isolation discharge structure 9 is installed on the top of the heating box 1. The isolation discharge structure 9 includes a rectangular cover 10 fixedly installed on the top of the heating box 1. A first dual-shaft motor 11 is fixedly installed on the top of the heating box 1. A cover plate 12 is fixedly connected to the output end of the first dual-shaft motor 11.

[0030] The negative pressure gas storage structure 13 is connected to the heating box 1.

[0031] In use, the support frame 5 carries the brake disc to be processed, and the electric heating rod 2 heats the surface coating of the brake disc for sintering and curing. When the processed brake disc needs to be removed, the lifting support frame 7 moves the grabbing frame 8, and the grabbing frame 8 moves the support frame 5 onto the lifting support frame 7. Then, the lifting support frame 7 lifts the support frame 5, causing it to move towards the rectangular cover 10. The negative pressure air storage structure 13 performs air intake to reduce the air pressure in the heating box 1. After the rectangular cover 10 is connected to the lifting support frame 7, the first dual-output shaft motor 11 drives the cover plate 12 to rotate. The personnel remove the support frame 5 from the lifting support frame 7 to obtain the processed brake disc. Then, the support frame 5 with the brake disc to be processed is placed on the lifting support frame 7. The first dual-output shaft motor 11 drives the cover plate 12 to close the opening at the top of the rectangular cover 10. Then, the lifting support frame 7 descends, and the grabbing frame 8 moves the support frame 5 onto a set of fixed frames 4. This utility model, through the cooperation of the holding mechanism 3, the moving frame structure 6, the isolation discharge structure 9, and the negative pressure air storage structure 13, facilitates the removal of the processed brake disc by personnel when the heating box 1 is under negative pressure, avoiding burns to personnel from the hot air ejected from the heating box 1, and thus protecting personnel safety.

[0032] In one embodiment, the lifting frame 7 includes two sets of rails 14 fixedly connected to the heating box 1. The rails 14 are slidably connected to a lifting frame 15. The lifting frame 15 is fixedly connected to two sets of symmetrically arranged second dual-output shaft motors 16. The output ends of the second dual-output shaft motors 16 are fixedly connected to gears 17. The gears 17 are meshed with racks 18 fixedly connected to the heating box 1. A first motor 19 is fixedly installed in the middle of the lifting frame 15. The output shaft of the first motor 19 is fixedly connected to a rotating frame 20. The rotating frame 20 is hinged to two sets of connecting frames 21. The connecting frames 21 are hinged to a linkage frame 22 slidably connected to the lifting frame 15. The linkage frame 22 is connected to the grabbing frame 8. The lifting frame 15 is used to support the support frame 5. The second dual-output shaft motor 16 drives the gear 17 to rotate. The rotating gear 17 rolls on the rack 18 to adjust the height of the lifting frame 15. During this period, the lifting frame 15 slides along the track 14, thereby adjusting the height of the support frame 5 and the lifting frame 15. The first motor 19 drives the rotating frame 20 to rotate. The rotating frame 20 moves the connecting frame 21, causing the linkage frame 22 to slide relative to the lifting frame 15. The linkage frame 22 is used to move the grabbing frame part 8, thereby adjusting the distance between the two sets of grabbing frame parts 8. The lifting frame 15 abuts against the rectangular cover 10 to block the communication between the heating box 1 and the rectangular cover 10, preventing the continuous ejection of hot air from the heating box 1.

[0033] In one embodiment, the grabbing frame 8 includes a guide frame 23 fixedly connected to the linkage frame 22. A second motor 24 is fixedly connected to the guide frame 23, and a lead screw 25 is fixedly connected to the output shaft of the second motor 24. A slider 26, threadedly connected to the lead screw 25 and slidably connected to the guide frame 23, is fixedly connected to a clamping bracket 27. The second motor 24 drives the lead screw 25 to rotate, which in turn drives the slider 26 to move. The moving slider 26 then moves the clamping bracket 27, which engages with the support frame 5. As the clamping bracket 27 moves toward the lifting frame 15, it moves the support frame 5 onto the lifting frame 15.

[0034] In one embodiment, the negative pressure gas storage structure 13 includes a gas storage tank 28 fixedly connected to the heating chamber 1. The gas storage tank 28 is fixedly connected to a first control valve 29, which is fixedly connected to a vacuum pump 30. The gas storage tank 28 is also fixedly connected to two sets of second control valves 31. When the first control valve 29 is opened, the vacuum pump 30 draws in hot air and injects it into the gas storage tank 28 to reduce the air pressure inside the heating chamber 1. As the second control valves 31 are opened, the hot air in the gas storage tank 28 re-enters the heating chamber 1 to restore the air pressure inside the heating chamber 1.

[0035] Example 2, based on Example 1, see [link / reference] Figure 1 and Figure 2 A pressure sensor 32 and a temperature sensor 33 are fixedly installed inside the heating chamber 1. The pressure sensor 32 is used for pressure detection, and the temperature sensor 33 is used for temperature detection.
