Description

Technical Field

[0001] This patent relates to the technical field of brake drum production, specifically a brake drum painting device. Background Art

[0002] The brake drum is a part of the drum brake system. When braking, the piston applies pressure to two pairs of half-moon-shaped brake shoes, making them close to the inner wall of the drum chamber, thereby generating friction to stop the rotation of the wheel. After the brake drum is produced, it is necessary to spray paint on the outer side. The existing painting device consists of a base and a motor. A support rod is installed on the rotating shaft of the motor, which is supported on the inner wall of the brake drum by the support rod. However, the bottom of the brake drum is in a vacant state. When the clamping is unstable, it is easy to make the brake drum fall, affecting the quality of painting. For this reason, we propose a brake drum painting device. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this patent is to provide a brake drum painting device. This patent provides a turntable groove on the top of the base, in which a rotatable turntable is provided. A column with a square groove is installed on the top of the turntable. The bottom end of the square rod can be inserted into the square groove. A pressure plate controlled by a spring is provided on the side wall of the square rod. The elasticity of the spring can make the pressure plate fit tightly on the inner wall of the brake drum. When the square rod rotates, the turntable and the brake drum will be driven to rotate at the same time. The brake drum is supported by the turntable to prevent the brake drum from falling during the painting process, thereby ensuring the quality of painting.

It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the contents of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0020] A bracket 8 is fixedly installed on the top of the base 1, a motor 9 is fixedly installed on the bottom of the bracket 8, a rotating column 10 is fixedly installed on the bottom end of the rotating shaft of the motor 9, a square groove 11 is provided at the bottom end of the rotating column 10, a square rod 12 is slidably installed on the inner side wall of the square groove 11, the bottom end of the square rod 12 is inserted into the square groove 7, two sliding holes 13 are provided on the side wall of the square rod 12, a sliding rod 14 is slidably installed on the inner side wall of the sliding hole 13, a circular plate 15 is fixedly installed on one end of the sliding rod 14, a spring 16 is sleeved on the side wall of the sliding rod 14, two ends of the spring 16 are respectively fixedly installed on the square rod 12 and the circular plate 15, a pressure plate 17 is fixedly installed on the other end of the sliding rod 14, and the pressure plate 17 fits tightly on the inner side wall of the brake drum.

[0021] Figure 2 The spring 16 shown is in a stretched and elongated state, and the pressure plate 17 is pressed against the inner wall of the brake drum by the rebound effect of the spring 16 .

[0022] A worker holding a spray gun can spray paint the brake drum at the right side of the base 1 .

[0023] Specifically, a driving power source for the motor 9 is provided on the top of the base 1 .

[0024] Specifically, a baffle 18 is integrally formed on the left side of the top of the base 1 , and the height of the baffle 18 is higher than the height of the brake drum.

[0025] The baffle 18 can prevent the paint sprayed by the spray painter on the right from being sprayed to the left and polluting the environment.

[0026] Specifically, the pressure plate 17 includes a plate body 19 , and wheel grooves 20 are provided on both upper and lower sides of the outer side of the plate body 19 . A pressure wheel 21 is connected to the wheel groove 20 via a pin shaft, and the pressure wheel 21 fits tightly on the inner wall of the brake drum.

[0027] Specifically, the outer side surface of the plate body 19 does not contact the inner side wall of the brake drum.

[0028] If the side surface of a plate body slides directly on the inner wall of the brake drum, the friction is large and it is inconvenient to operate. When the square rod 12 is moved upward or downward, the pressure wheel 21 can roll on the inner wall of the brake drum to reduce friction and facilitate operation.

[0029] Specifically, the side wall of the slide bar 14 is provided with four strip-shaped grooves 22 .

[0030] The provision of the strip-shaped groove 22 can reduce the contact area between the side wall of the slide bar 14 and the inner wall of the slide hole 13 , thereby increasing the sliding effect of the contact surface when the slide bar 14 slides.

[0031] Working principle: A worker holding a spray gun can spray paint on the brake drum at the right side of the base 1, and at the same time control the motor 9 to drive the rotating column 10 to rotate, and the rotating column 10 drives the square rod 12, the turntable 5 and the brake drum to rotate. After the painting is completed, turn off the motor 9 and move the square rod 12 upward to disengage the square rod 12 from the square groove 7, and at the same time, the pressure plate 17 disengages from the brake drum.

[0032] It should be noted that the equipment structure and drawings of this patent mainly describe the principles of this patent. In terms of the technology of this design principle, the settings of the device's power mechanism, power supply system and control system are not fully described. However, on the premise that technical personnel in this field understand the principles of the above patent, they can clearly know the details of its power mechanism, power supply system and control system.

[0033] This patent provides a turntable groove on the top of the base, in which a rotatable turntable is provided, and a column with a square groove is installed on the top of the turntable. The bottom end of the square rod can be inserted into the square groove, and a pressure plate controlled by a spring is provided on the side wall of the square rod. The elasticity of the spring can make the pressure plate fit tightly on the inner wall of the brake drum. When the square rod rotates, it will drive the turntable and the brake drum to rotate at the same time. The brake drum is supported by the turntable to prevent the brake drum from falling during the painting process, thereby ensuring the quality of painting.
