Description

Technical Field

[0001] This utility model relates to the field of coating device technology, and in particular to a coating device for annular workpieces. Background Technology

[0002] After the workpiece is manufactured, in order to enhance its surface corrosion resistance, it is generally necessary to spray paint on the outer surface of the workpiece. When painting the surface of large ring workpieces or multiple small parts, it is usually necessary to support the ring workpiece at a certain height above the ground by various forms of support structures before spraying.

[0003] A search of Chinese patent CN217288983U reveals a painting device for a ring-shaped workpiece, comprising a rotating support and a spraying device. The spraying device includes a horizontally arranged first support frame, a height adjustment mechanism mounted on the first support frame, and a spraying mechanism. The height adjustment mechanism includes an adjustment base and an adjustment plate passing through the adjustment base and positioned vertically. The adjustment base can drive the adjustment plate to move vertically, and the spraying mechanism is mounted on the adjustment plate. When it is necessary to spray the outer part of the ring-shaped workpiece, the height of the spraying mechanism is lowered for spraying; when it is necessary to spray the inner part of the ring-shaped workpiece, the height of the spraying mechanism is raised, so that the spraying range of the spraying mechanism can cover this area, achieving comprehensive and uniform spraying of the ring-shaped workpiece and ensuring paint quality.

[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned painting equipment: Although the existing technology can spray the inner and outer surfaces of the ring-shaped workpiece by adjusting the height of the spraying mechanism, its spraying efficiency is not high, and it can only spray the inner or outer surface of the ring-shaped workpiece separately. Based on this, the present invention designs a ring-shaped workpiece coating device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a ring-shaped workpiece coating device to solve the problem of insufficient coating efficiency in the prior art mentioned in the background section.

The ball screw is connected to the T-shaped plate through a ball nut. A rotary motor is installed on one side wall of one of the fixed bases, and the output end of the rotary motor is connected to one end of the ball screw.

[0011] As a preferred embodiment, a guide support rod is installed on one side wall of the drive plate, and the guide support rod is slidably engaged with the fixed vertical plate.

[0012] As a preferred embodiment, guide sleeves are respectively installed on the top outer wall of the T-shaped plate, and the guide sleeves are slidably engaged with the guide vertical plate.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] By pulling the second support plate, the position of the nozzle on the first support plate can be changed.

Equipped with a support spring 13, when spraying a ring-shaped workpiece, the guide plate 11 can be pulled to disengage the fixing rod 12 from the positioning hole on the support horizontal plate 4. Then, the support horizontal plate 4 can be pulled to change the position of the nozzle 7 on the support vertical plate 5. Simultaneously, the support base 3 can be rotated, allowing the support horizontal plate 4 to rotate the nozzle 7 on the support vertical plate 5 by 180°, thus adjusting the position of the nozzle 7. By continuing to pull the guide plate 11, the fixing rod 12 disengages from the positioning hole on the support horizontal plate 1, and the support base 2 can be slid to move the support base 3, further adjusting the position of the nozzle 7 on the support vertical plate 5. This device, by flexibly adjusting the position of the nozzle 7, can effectively spray workpieces of different sizes. Furthermore, during spraying, it can simultaneously spray the inner and outer surfaces of a ring-shaped workpiece, or simultaneously spray the outer or inner surface of the workpiece, greatly improving the spraying efficiency.

[0022] In this embodiment, an electric push rod 14 is installed on one side wall of the fixed vertical plate 9. A drive plate 15 is connected to the output end of the electric push rod 14. A T-shaped plate 16 is installed on one side wall of the drive plate 15. Guide vertical plates 19 are slidably engaged on the T-shaped plate 16. The guide vertical plates 19 are connected to the support horizontal plate 1. A fixed base 17 is installed on one side wall of one of the guide vertical plates 19.

When spraying coating on annular workpieces, by pulling the guide plate 11, the fixing rod 12 is disengaged from the positioning hole on the supporting horizontal plate 4. Then, by pulling the supporting horizontal plate 4, the position of the nozzle 7 on the supporting vertical plate 5 can be changed. At the same time, the guide plate 11 can be pulled further to disengage the fixing rod 12 from the positioning hole on the supporting horizontal plate 1. Then, the supporting base 2 can be slid, which can drive the supporting base 3 to move, thereby further adjusting the position of the nozzle 7 on the supporting vertical plate 5. Furthermore, when the fixing rod 12 is disengaged from the positioning hole on the second support plate 4, the second support base 3 can be rotated, so that the second support plate 4 can drive the nozzle 7 on the first support plate 5 to rotate 180°, thereby adjusting the position of the nozzle 7. Therefore, the device is equipped with two nozzles 7, and the position of the nozzles 7 can be flexibly adjusted, so that the device can effectively spray workpieces of different sizes. Moreover, during spraying, the inner and outer surfaces of the ring-shaped workpiece can be sprayed simultaneously, or the outer or inner surface of the workpiece can be sprayed simultaneously, thereby greatly improving the spraying efficiency.
