Description

Technical Field

[0001] This invention relates to a coating preparation apparatus, and more particularly to an apparatus for coating preparation in which multiple parts can be mounted and rotated at multiple angles. Background Technology

[0002] Current coating preparation equipment cannot ensure that all end faces of the parts are perpendicular to the spraying direction, resulting in uneven coating thickness on different surfaces. Furthermore, the coating material cannot be deposited to form columnar crystals, affecting its heat insulation and erosion resistance effects, and failing to achieve the purpose of coating preparation. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention discloses a device for coating preparation that is simple in structure, easy to operate, and enables multiple parts to be mounted and rotated at multiple angles to obtain an all-round coating.

[0004] The technical solution adopted in this invention is:

[0005] A device for coating preparation, capable of mounting multiple parts and rotating at multiple angles, includes a transfer box and a part driving device. The part driving device includes coating preparation parts, a hollow shaft, a mandrel, large bevel gears, and small bevel gears. The hollow shaft is mounted on a machine base via bearings, with one end connected to the driving device. The mandrel is housed within the hollow shaft, with one end extending out of the hollow shaft and fixed to the machine base. Several large bevel gears are mounted on the mandrel, each meshing with several small bevel gears. The shafts of the small bevel gears extend out of the hollow shaft, and part clamps are mounted on the shafts of the small bevel gears. The part clamps are located outside the hollow shaft, and each part clamp mounts one coating preparation part. The coating preparation parts are located inside the transfer box.

[0006] Furthermore, the drive device is mounted on the base, and the drive device is a motor. The drive device is connected to the hollow shaft through a gear transmission device.

[0007] Furthermore, the base is mounted on a track, which is set parallel to the axis of the hollow shaft.

[0008] Furthermore, it includes two part driving devices, which are placed at both ends of the transfer box. The transfer box is divided into loading chamber I, deposition chamber and loading chamber II by two partitions. The two partitions can move perpendicular to the axis of the hollow shaft, so that loading chamber I, deposition chamber and loading chamber II are connected. The coating preparation parts on the two part driving devices are located in loading chamber I and loading chamber II respectively.

[0009] Furthermore, the gear transmission device includes a driven gear fixed on the outer wall of the hollow shaft and a driving gear mounted on the output shaft of the drive device, wherein the driven gear meshes with the driving gear.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The present invention has a simple structure and is easy to operate. The hollow shaft of the present invention is equipped with a part fixture, and the inner end of the rotating shaft of the part fixture is provided with a small bevel gear, which meshes with the large bevel gear of the mandrel. The driving device drives the hollow shaft to rotate, thereby causing the part fixture to rotate, so that all end faces of the part can have the opportunity to be perpendicular to the spraying direction, which makes the spraying uniform and the coating has good heat insulation and erosion resistance.

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] like Figure 1 and Figure 2 As shown, the present invention includes a transfer box and two part driving devices. The two part driving devices are located at both ends of the transfer box, which is divided into a loading chamber I3, a deposition chamber 1, and a loading chamber II5 by two partitions 2 and 4. The part driving device includes a coating preparation part 6, a hollow shaft 7, a mandrel 8, a large bevel gear 14, and a small bevel gear 13. The hollow shaft 7 is mounted on a base 9 via bearings, and one end of the hollow shaft 7 is connected to a driving device 11, which can drive the hollow shaft 7 to rotate. The hollow shaft 7 houses the mandrel 8, one end of which extends out of the hollow shaft 7 and is fixedly mounted on the base 9. The mandrel 8 cannot rotate. Several large bevel gears 14 are mounted on the mandrel 8, and each large bevel gear 14 meshes with four small bevel gears 13. The shafts of the small bevel gears 13 extend out of the hollow shaft 7, and part clamps are provided on the shafts of the small bevel gears 13. The part clamps are located outside the hollow shaft, and each part clamp is equipped with a coating preparation part 6.

[0017] The two partitions 2 and 4 can move perpendicular to the axis of the hollow shaft 7 of the part driving device, thereby connecting the loading chamber I3, the deposition chamber 1, and the loading chamber II 5. The coating preparation parts 6 on the two part driving devices are located in the loading chamber I3 and the loading chamber II 5, respectively. The base is mounted on the track 12, which is arranged parallel to the axis of the hollow shaft 7.

[0018] The drive device 11 is mounted on the base 9. The drive device 11 is an electric motor and is connected to the hollow shaft 7 via a gear transmission device 10. The gear transmission device 10 includes a driven gear fixed on the outer wall of the hollow shaft 7 and a driving gear mounted on the output shaft of the drive device 11. The driven gear meshes with the driving gear.

[0019] When using this invention, the coated part 6 is prepared according to... Figure 1 After being installed on the hollow shaft 7, the drive device drives the hollow shaft 7 to rotate through the gear transmission device. The spindle 8 and the large bevel gear 14 are stationary. While the small bevel gear 13 rotates around the stationary large bevel gear, the small bevel gear 13 also rotates on its own axis. The part to be prepared and the small bevel gear 13 synchronously make circular motion and 360° rotation around the axis.
