A swing cylinder is fixedly installed on the bracket. A coupling is fixedly installed on the movable end of the swing cylinder. A workpiece support plate is fixedly installed on the coupling. Workpiece fixing bases are symmetrically and fixedly installed on the workpiece support plate. Blowing nozzles I are arranged on the workpiece support plate corresponding to the workpiece fixing bases. A plurality of air delivery pipes I and air delivery pipes II are fixedly installed on the fixed frame. A plurality of blowing nozzles II are communicated with each air delivery pipe I. A blowing nozzle III is communicated with the air delivery pipe II.

[0006] Further, a laser sensor is fixedly installed on the fixed frame, and the laser sensor is electrically connected with the swing cylinder.

[0007] Further, a shaft sleeve is sleeved outside the coupling.

[0008] Further, a valve I is arranged at one end of the air delivery pipe I extending outside the fixed frame, and a valve II is arranged at one end of the air delivery pipe II extending outside the fixed frame.

[0023] A drying mechanism for a constant velocity universal joint after quenching, comprising a support table 1 fixedly installed on the wall and a fixed frame 2, and a constant velocity universal joint flipping and drying assembly is cooperatively arranged between the support table 1 and the fixed frame 2;

[0024] The constant velocity universal joint flipping and drying assembly includes a bracket 3 located on the support table 1, a swing cylinder 4 is fixedly installed on the bracket 3, a coupling 5 is fixedly installed on the movable end of the swing cylinder 4, a workpiece support plate 6 is fixedly installed on the coupling 5, workpiece fixing bases 7 are symmetrically and fixedly installed on the workpiece support plate 6, and the workpiece fixing bases 7 are pre-produced according to the shape of the workpiece and can fit with the workpiece to realize the fixation of the workpiece; blowing nozzles one 8 are arranged on the workpiece support plate 6 corresponding to the workpiece fixing bases 7, a plurality of first air delivery pipes 9 and second air delivery pipes 10 are fixedly installed on the fixed frame 2, a plurality of blowing nozzles two 11 are communicated with the first air delivery pipes 9, and a blowing nozzle three 12 is communicated with the second air delivery pipe 10;

[0025] As can be seen from the above description, when the workpiece is placed on the workpiece fixing base 7, the swing cylinder 4 is controlled to flip, and the swing cylinder 4 will perform an action mode of reciprocating clockwise and counterclockwise; when the workpiece is moved into the fixed frame 2, the blowing nozzles one 8, the blowing nozzles two 11 and the blowing nozzle three 12 start to dry the workpiece. After the workpiece is dried, it will be sent back to the original position and taken away by a truss manipulator.

[0026] As a technical optimization scheme of the present utility model, a laser sensor 13 is fixedly installed on the fixed frame 2, and the laser sensor 13 is electrically connected to the swing cylinder 4;

[0027] As can be seen from the above description, the laser sensor 13 can realize the automation requirements of the overall operation through mutual linkage with the swing cylinder 4.

[0028] As a technical optimization scheme of the present utility model, a shaft sleeve 14 is sleeved and connected outside the coupling 5;

[0029] As can be seen from the above description, the shaft sleeve 14 provides certain protection for the coupling 5.

[0030] As a technical optimization solution of the present utility model, one end of the first gas pipeline 9 extending outside the fixed frame 2 is provided with a first valve 15, and one end of the second gas pipeline 10 extending outside the fixed frame 2 is provided with a second valve 16;

[0031] As can be seen from the above description, by controlling the first valve 15 and the second valve 16, the on-off of the first gas pipeline 9 and the second gas pipeline 10 can be controlled, which is convenient for maintenance and repair.

[0032] As a technical optimization solution of the present utility model, the first blowing nozzle 8 is located at the center position of the workpiece fixing base 7;

[0033] As can be seen from the above description, the first blowing nozzle 8 is mainly used to dry the bottom and groove parts of the workpiece.

[0034] As a technical optimization solution of the present utility model, splash-proof plates 17 are symmetrically and fixedly installed on both sides of the fixed frame 2;

[0035] As can be seen from the above description, the splash-proof plates 17 can block the splashing of water droplets caused by the high-speed airflow blowing on the workpiece, protecting the working environment.

[0036] As a technical optimization solution of the present utility model, the first gas pipeline 9 and the second blowing nozzle 11 are both arranged around the adjacent workpiece fixing base 7;

[0037] As can be seen from the above description, the second blowing nozzle 11 is mainly used to dry the moisture on the side of the workpiece. The arrangement method with the workpiece fixing base 7 as the center can make the drying area of the second blowing nozzle 11 on the side of the workpiece larger, effectively improving the drying efficiency.

[0038] Working principle:

[0039] The truss manipulator transports the workpiece after cooling to the loading station, places the workpiece on the workpiece fixing base 7 so that the workpiece is fixed. The laser sensor 13 detects the workpiece and sends an electrical signal to the swing cylinder 4. The swing cylinder 4 drives the workpiece support plate 6 to flip 180°, driving the workpiece into the fixed frame 2. The first blowing nozzle 8 dries the groove part of the workpiece, and the second blowing nozzle 11 and the third blowing nozzle 12 dry the rod part of the workpiece (the first blowing nozzle 8 does not stop blowing). At the same time, the next workpiece is transported to the loading position. After the workpiece in the fixed frame 2 is dried, the swing cylinder 4 rotates 180°. The completely dried workpiece returns to the loading position, and then is unloaded by the truss manipulator to vacate the loading position, and so on in a cycle.

[0040] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the specific implementation manners is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
