[0020] Reference Figures 1 to 4As shown, the utility model provides a carbon fiber composite material fan impeller curing device, comprising: a curing tank 1, a driving assembly 2 and a curing box 3, a tank door 11 is provided on one side of the curing tank 1, and a horizontal handle threaded rod 111 is screwed inside the tank door 11, and the inner end of the handle threaded rod 111 is connected with an extrusion block 112, the driving assembly 2 is installed at the upper end of the curing tank 1, and the driving assembly 2 includes a fixing frame 22, and a pressurization or vacuum pipe 23 is movably connected to the inner side of the fixing frame 22, the curing box 3 is slidably connected to the inner side of the curing tank 1, and the curing box 3 includes an upper cover 31 and a lower cover 32 hinged thereto, and a positioning cavity 33 is opened in the lower cover 32, a partition 34 is provided between the positioning cavities 33, and a clamping block 35 is provided inside the positioning cavity 33, one end of the clamping block 35 is connected with an elastic telescopic rod 36, and the elastic telescopic rod 36 is horizontally fixed to one side of the partition 34.

[0021] In this embodiment, the curing tank 1, the driving assembly 2 and the curing box 3 constitute the main structure of the carbon fiber composite material fan impeller curing equipment involved in this application, which is used to perform heating and curing operations on the fan impeller made of carbon fiber composite material.

[0022] Specifically, the tank door 11 is configured as a semi-hollow circle structure, and when the tank door 11 is opened, the extrusion block 112 is moved outward into the arc-shaped cavity of the hollow circle by rotating the handle threaded rod 111, thereby not affecting the normal opening and closing of the tank door 11.

[0023] Specifically, the external structure of the curing box 3, including the connection between the upper cover 31 and the lower cover 32, and the opening method are consistent with the relevant structures involved in the comparative documents in the background technology. In this application, only the internal structure of the curing box 3 is modified.

[0024] Specifically, the elastic telescopic rod 36 includes a fixed sleeve and a sliding rod slidably inserted in the sleeve, and a spring is sleeved on the outer side of the sliding rod. At the same time, the outer end of the sliding rod is connected to the clamping block 35.

[0025] like Figure 2 As shown, one side of the curing tank 1 is set as an open mouth 12, and the tank door 11 is rotatably connected to the outside of the open mouth 12, and the handle connected to the outer end of the handle threaded rod 111 is located on the outside of the tank door 11, the curing tank 1 includes an outer insulation layer 17, and a heating layer 15 is provided on the inner side of the insulation layer 17, and an inner wall 14 is provided on the inner side of the heating layer 15, a guide groove 13 is opened on the upper end of the bottom inner wall 14 of the curing tank 1, and a limit block 16 is provided on the side of the guide groove 13 away from the tank door 11, and a roller installed at the bottom of the curing box 3 is rollingly connected to the guide groove 13.

[0027] Specifically, two parallel groups of guide grooves 13 are provided, and the rollers at the bottom of the curing box 3 are made of metal.

[0028] It should be noted that, in the process of pulling the curing box 3 outward, a flatbed truck having the same height as the guide groove 13 is pre-arranged at the open mouth 12 of the curing tank 1 , so as to receive the curing box 3 .

[0029] like Figure 1 and Figure 2 As shown, a cylinder 21 is installed on the upper end of the fixing frame 22, and the piston rod end of the cylinder 21 slides downward and passes through the top plate of the fixing frame 22, and a connecting plate 24 is connected to the lower end of the piston rod end, and the pressurization or vacuum pipe 23 slides through the top wall of the curing tank 1, and the lower end of the pressurization or vacuum pipe 23 is inserted into the plug hole opened on the top of the curing box 3, and the connecting plate 24 is fixed to the outer wall of the pressurization or vacuum pipe 23.

[0031] When in use, open the tank door, pull out the curing box, then open the upper cover, and clamp the fan impeller to be cured in the positioning cavity through the clamping block and the elastic telescopic rod to achieve independent positioning of the impeller to prevent its shaking from causing scratches and affecting the quality. Then close the upper cover, and then push the curing box into the curing tank along the guide groove through the roller at the bottom, limit its end with the limit block, and then close the tank door, and drive the pressure block to squeeze and limit the front end of the curing box by turning the handle threaded rod, so as to facilitate the positioning of the curing box; after the curing box is positioned, start the cylinder to drive the connecting plate to drive the pressurized or vacuum pipe to move downward. At this time, since the front and rear ends of the curing box are restricted, the pipe can move downward to align with the top of the inserted curing box and connect with the positioning cavity, so that the curing box can be pressurized or vacuumed.

[0032] The carbon fiber composite material fan impeller curing equipment of the utility model can effectively solve the problem that the existing carbon fiber composite material axial flow fan impeller curing device lacks the positioning effect of the impeller and the curing equipment, resulting in inconvenience in the curing quality of the impeller and the connection of the connecting pipe.
