Description

Technical Field

[0001] This invention relates to the field of brake drum anti-rust processing technology, specifically to a brake drum anti-rust spraying equipment. Background Technology

[0002] Drum brakes utilize a brake transmission mechanism to press the brake shoes against the brake friction pads inside the brake drum, thereby generating braking force. This allows the wheels to slow down or stop within the shortest distance as needed, ensuring driving safety and preventing the car from slipping automatically when parked. The reinforcement process for brake drums includes rust prevention treatment of the inside of the brake drum.

[0003] Existing brake drum anti-rust spraying equipment cannot achieve complete automation of the process. Manual assistance is still required to spray the brake drums, resulting in low processing efficiency. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] Please see Figures 1-3 One type of brake drum anti-rust spraying equipment includes:

[0037] The housing 1 has a second processing chamber 7 and a first processing chamber 2 at one end;

[0038] The spraying device is installed inside the second processing chamber 7 and the first processing chamber 2;

[0039] The spraying device includes a clamping table 10, a jaw 11, and a spray head 15. The upper end of the clamping table 10 is equipped with a jaw 11, which is used to abut against the inner wall of the brake drum 6. The spray head 15 is slidably connected to the interior of the second processing chamber 7 and the first processing chamber 2, and is used to slide into the interior of the brake drum 6 for spraying.

[0040] Protective plate 12 is slidably connected to one end of housing 1 and is used to seal the first processing chamber 2 and the second processing chamber 7.

[0041] Hydraulic push rod 8, one end of which is installed at one end of housing 1, is used to push the spraying device into the interior of the first processing chamber 2 and the second processing chamber 7;

[0042] One end of the housing 1 is also equipped with a first pneumatic push rod 13, one end of which is connected to one end of the protective plate 12. The protective plate 12 is controlled to slide up and down by the first pneumatic push rod 13.

[0043] Eight support seats 20 are installed at the lower end of the housing 1, and the eight support seats 20 are distributed on both sides of the lower end of the housing 1.

[0044] according to Figure 1 As shown, a second processing chamber 7 and a first processing chamber 2 are respectively provided, and rust-preventive oil and rust-preventive liquid can be sprayed simultaneously through the second processing chamber 7 and the first processing chamber 2;

[0045] The brake drum 6 is placed on the upper end of the clamping table 10. Then, the chuck 11 is energized and unfolds to abut against the inner wall of the brake drum 6, thereby clamping the chuck 11. Then, the protective plate 12 is slid down to seal the second processing chamber 7 or the first processing chamber 2, so that the second processing chamber 7 or the first processing chamber 2 forms a sealed space, thereby reducing safety hazards and reducing the possibility of rust-preventive oil or rust-preventive liquid escaping from the second processing chamber 7 or the first processing chamber 2 and floating out of the housing 1 when applying rust-preventive oil or rust-preventive liquid.

[0046] Automated spraying is achieved by inserting the nozzle 15 into the brake drum 6 and then rotating the fixture table 10. After spraying, the protective plate 12 is opened, its claws 11 are reset, and the sprayed brake drum 6 is removed from the fixture table 10, thus completing the processing.

[0047] It also includes a limiting frame 3, which is installed at the lower end of the first processing chamber 2 and the second processing chamber 7;

[0048] Slide 4 is slidably connected inside the limit frame 3;

[0049] The slide rail 5 is installed on the upper end of the limit frame 3. The upper end of the slide table 4 is equipped with a platform 17. The lower end of the clamp table 10 is connected to the upper end of the platform 17. The lower end of the platform 17 is slidably connected to the upper end of the slide rail 5.

[0050] according to Figure 1 and Figure 2 As shown, in order to facilitate manual loading and unloading, a limiting frame 3 and a slide table 4 are set at one end of the housing 1. The slide table 4 is pushed to one end by a hydraulic push rod 8, so that the slide table 4 drives the fixture table 10 to slide out from the first processing chamber 2 or the second processing chamber 7 to one end of the housing 1, thereby facilitating manual loading and unloading.

[0051] An L-shaped plate 9 is installed at one end of the fixture table 10, and the other end of the hydraulic push rod 8 is connected to one end of the L-shaped plate 9;

[0052] The lower end face of the downward sliding protective plate 12 is used to abut against the upper end of the table 17 to seal the first processing chamber 2 and the second processing chamber 7.

[0053] To better seal the second processing chamber 7 and the first processing chamber 2, a platform 17 is provided at the upper end of the slide table 4. When the slide table 4 and the fixture table 10 are located at the second processing chamber 7 or the first processing chamber 2, the lower end of the protective plate 12 is slid down to abut against the upper end of the platform 17, thereby completely sealing the second processing chamber 7 or the first processing chamber 2 and further reducing the possibility of rust-preventive oil or rust-preventive liquid escaping from the second processing chamber 7 or the first processing chamber 2 and drifting out of the housing 1.

[0054] A support column 19 is also installed on the upper end of the clamping table 10. The support column 19 is installed on one side of the chuck 11 and is used to support the brake drum 6.

[0055] The upper end of the limit frame 3 is also equipped with a bearing ring 16, and the lower end of the fixture table 10 passes through the bearing ring 16 and fits against the inner wall of the bearing ring 16.

[0056] The slide table 4 is equipped with a drive unit, and the output shaft of the drive unit is connected to the lower end of the fixture table 10.

[0057] The drive device includes a motor, which is connected to the lower end of the fixture table 10 through the output shaft of the motor. When the fixture table 10 needs to rotate, the motor is powered on and drives the fixture table 10 to rotate through the output shaft of the motor. The fixture table 10 and the table plate 17 are connected and supported by a bearing ring 16 to reduce friction.

[0058] A slide block 14 is installed on the upper end of the housing 1. One end of the slide block 14 is connected to the upper end of the nozzle 15. The slide block 14 drives the nozzle 15 to move closer to the brake drum 6.

[0059] A protective shell 18 is installed at one end inside the housing 1. The protective shell 18 is used to wrap the outer surface of the hydraulic push rod 8. One end of the protective shell 18 is open.

[0060] The size of the L-shaped plate 9 is adapted to the size of one end opening of the protective shell 18. The L-shaped plate 9 is used to seal one end opening of the protective shell 18.

[0061] according to Figure 3 As shown, after the spraying is completed, the hydraulic push rod 8 is activated, and the slide table 4 is pushed to slide by the hydraulic push rod 8, thereby pushing the slide table 4 and the fixture table 10 to one end of the housing 1;

[0062] It should be noted that, since rust-preventive oil or rust-preventive liquid may leak into the hydraulic push rod 8 and cause long-term cumulative damage to the mechanical properties of the hydraulic push rod 8, a protective shell 18 is provided on the outer surface of the hydraulic push rod 8, and an L-shaped plate 9 is installed on the upper end of the platform 17. The width of the L-shaped plate 9 is adapted to the opening at one end of the protective shell 18. Thus, when the hydraulic push rod 8 pulls the L-shaped plate 9 to slide into the housing 1, the L-shaped plate 9 is sealed to the opening at one end of the protective shell 18, thereby reducing the possibility of rust-preventive oil or rust-preventive liquid contaminating the hydraulic push rod 8.

[0063] A second pneumatic push rod is also installed at one end of the slide ram 14, and the lower end of the second pneumatic push rod is connected to the upper end of the nozzle 15.

[0064] according to Figure 1As shown, the slide block 14 drives the second pneumatic push rod to move to the axis of the brake drum 6, and the second pneumatic push rod drives the nozzle 15 to slide downward and insert into the interior of the brake drum 6, thereby improving the automation of the brake drum 6 processing;

[0065] It should be noted that a first pneumatic push rod 13 is also installed at one end of the housing 1. When the nozzle 15 slides down and inserts into the brake drum 6, the first pneumatic push rod 13 drives the protective plate 12 to slide against the table 17, thereby sealing the first processing chamber 2 or the second processing chamber 7.
