Description

Technical Field

[0001] This utility model belongs to the field of parts cleaning and drying technology, and more specifically relates to a vacuum drying device. Background Technology

[0002] Currently, the drying of complex machined parts after cleaning usually involves blowing air through a jet pipe to remove water from the surface of the parts using high-pressure gas. Then, the parts are further dried by heating or hot air. However, this is inefficient on a continuous cleaning and drying line, where the previous part is often cleaned before the next part has finished drying. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a vacuum drying device with high drying efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vacuum drying device, including a base, a positioning fixture on the base, a liftable sealing cover above the base, a drive mechanism connected to the sealing cover, and a vacuum device connected to the sealing cover.

[0005] Furthermore, the base is provided with two rows of roller groups, each row of roller groups is provided with several rollers, the roller groups are used to support the positioning fixture, and the positioning fixture is moved by the roller groups.

[0006] Furthermore, a guide plate is provided on one side of the roller assembly, and a positioning plate corresponding to the guide plate is provided on the positioning fixture, and the positioning plate contacts the rollers of the roller assembly.

[0007] Furthermore, the positioning fixture includes a support plate, on which a plurality of support blocks and a plurality of contour positioning blocks are provided, and the positioning plate is located below the support plate.

[0008] Furthermore, a sealing strip is provided on the opening of the sealing cover.

[0009] Furthermore, the drive mechanism includes a bracket, on which a lifting cylinder and a guide rod are mounted. The piston rod of the lifting cylinder is connected to a sealing cover. The guide tube is slidably connected to the bracket and connected to the sealing cover. The guide rod is a hollow rod with an internal through hole connecting the sealing cover and a vacuum device.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the parts are positioned by the positioning fixture, the positioning fixture is transported to the roller group of the base by the conveying system, the sealing cover descends to cover the parts in the sealed space formed by the sealing cover, and the air in the sealed space is extracted by the vacuum device connected by the hollow guide rod, so that the residual water droplets on the parts evaporate due to the low pressure and are discharged with the hollow guide rod, thereby achieving vacuum drying with high drying efficiency.

[0015] Reference Figure 1 and Figure 2 The present invention will be further described below.

[0016] A vacuum drying device includes a base 1, a positioning fixture 2 on the base 1, a liftable sealing cover 3 above the base 1, a drive mechanism connected to the sealing cover 3, and a vacuum device (not shown in the figure).

[0017] like Figure 1 As shown in this example, preferably, the base 1 is provided with two rows of roller groups 4, each row of roller groups 4 is provided with several rollers, the roller groups 4 are used to support the positioning fixture 2, and the positioning fixture 2 is moved by the roller groups 4.

[0018] like Figure 1As shown in this example, preferably, a guide plate 5 is provided on one side of the roller assembly 4, and a positioning plate 6 corresponding to the guide plate 5 is provided on the positioning fixture 2, and the positioning plate 6 contacts the rollers of the roller assembly 4.

[0019] like Figure 2 As shown in the example, the preferred embodiment of this example includes a support plate 7, on which a plurality of support blocks 8 and a plurality of contour positioning blocks 9 are provided, and the positioning plate 6 is located below the support plate 7.

[0020] like Figure 1 As shown in this example, preferably, the sealing cover 3 has a sealing strip 10 on its opening.

[0021] like Figure 1 As shown, in this preferred embodiment, the driving mechanism includes a bracket 11, on which a lifting cylinder (not shown in the figure) and a guide rod 12 are provided. The piston rod of the lifting cylinder is connected to a sealing cover 3. The guide rod 12 is slidably connected to the bracket 11 and connected to the sealing cover 3. The guide rod 12 is a hollow rod with an internal through hole that connects the sealing cover 3 and the vacuum device.

[0022] like Figure 1 and Figure 2 As shown, the parts to be dried are supported by the support blocks 8 on the support plate 7 and positioned by the contour positioning blocks 9. They are then moved to the roller group 4 on the base 1 by the conveying system. At the same time, the lateral position (vertical to the conveying direction) of the support plate 7 is positioned by the guide plate 5 on the base 1 and the positioning plate 6 on the support plate 7. After the positioning fixture 2 moves to the designated position, the lifting cylinder drives the sealing cover 3 to descend until the sealing strip 10 on the bottom opening of the sealing cover 3 is pressed against the base 1, covering the parts in the sealed space formed by the sealing cover 3. Finally, the air in the sealed space is extracted by the vacuum device connected by the hollow guide rod 12, so that the residual water droplets on the parts evaporate due to the low pressure and are discharged with the hollow guide rod 12, realizing vacuum drying with high drying efficiency.

[0023] Specifically, the entire process from cleaning to drying of the parts is transferred between each process by a conveyor system, which can accurately bring the positioning fixture 2 to a workstation.
