[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] Embodiment 1

[0023] A tooling for removing supports of 3D printed thin-walled parts, including a support rod 1. One end of the support rod 1 is provided with a screw rod 2, and the screw rods 2 are arranged in a circumferential array on the support rod 1. Each screw rod 2 is provided with a threaded sleeve 3. By adjusting the position of the threaded sleeve 3 on the screw rod 2, the inner cavity of the thin-walled part is supported. The other end of the support rod 1 is provided with a chute 4, and the chutes 4 are arranged in a circumferential array on the support rod 1. Each chute 4 is provided with a slider 5, and the slider 5 always contacts one end of the threaded sleeve 3 close to the support rod 1, and is used to compare the telescopic distance of the threaded sleeve 3. The screw rod 2 and the chute 4 are at both ends of the support rod 1, and their positions and quantities correspond one by one. The chute 4 is a T-shaped chute 4, the slider 5 is a T-shaped keyway slider 5, and the chute 4 is adapted to the slider 5. The T-shaped slider slides in the chute 4. Further, the slider 5 slides between the threaded sleeve 3 and the support rod 1, that is, the T-shaped slider just contacts the lower part of one end of the threaded sleeve 3 close to the support rod 1. Specifically, the side wall of the chute 4 is provided with scales, and the slider 5 cooperates with the scales to measure the telescopic distance of the threaded sleeve 3.

[0024] When this application is in use, the telescopic distance is adjusted by screwing the threaded sleeve and the screw rod. Then, the slider is just made to contact one end of the threaded sleeve close to the support rod, and the telescopic distance is observed. After adjusting to an appropriate length, this application can be placed inside the thin-walled part, so as to support the inner cavity of the thin-walled part, that is, mainly the inner cavity of the thin-walled part is supported by the end of the threaded sleeve. When removing the support by a fitter or the like in the subsequent process, it provides a certain support for the part, thereby preventing the thin-walled part from deforming and improving the finished product quality of the thin-walled part, and reducing the problems of deformation and scrapping of the thin-walled part during the support removal process.

[0025] Specifically, one end of the threaded sleeve 3 away from the support rod 1 is a smooth arc surface. Being set as a smooth arc surface, when in use, the smooth arc surface end contacts the inner cavity of the thin-walled part, which can reduce the possibility of scratching the inner cavity of the thin-walled part.

[0026] Specifically, one end of the screw rod 2 away from the support rod 1 is a smooth arc surface adapted to the threaded sleeve 3. When in use, the threaded sleeve 3 and the screw rod 2 can be adapted, so that they can smoothly screw in and out to adjust the support distance.

[0027] Specifically, there are eight screw rods 2, and eight threaded sleeves 3 are provided and are adapted to the screw rods 2. The quantity of the screw rods 2 can be selected according to the actual situation, and it is advisable to be able to play a symmetric and balanced supporting role.

[0028] Specifically, the chute 4 corresponds to the screw rod 2 in terms of quantity and position. Further, the slider 5 corresponds to the threaded sleeve 3 in the radial position.

[0029] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
