It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments may be combined with each other.

[0022] Some embodiments of the present utility model will be described below with reference to the accompanying drawings. Embodiment 1

[0023] Combined with Figures 1-4 As shown, this embodiment provides an automatic conversion numerical control tool, including: main body module 100.

[0024] Among them, the main body module 100 includes a base 110, a support 120 fixed on one side of the base 110, a ring-shaped part 130 rotatably sleeved on the support 120, pipe bodies 140 fixedly arranged in an annular array on the ring-shaped part 130, a rotating part 150 installed on the inner wall of the pipe body 140, a first driving part 160 installed in the inner cavity of the support 120 and extending into the support 120 to be embedded in the rotating part 150, electric telescopic rods 170 symmetrically fixed on the inner wall of the support 120 and connected to the first driving part 160, a tooth ring 180 fixed on one side of the ring-shaped part 130, and a second driving part 190 installed on the base 110 and meshing with the tooth ring 180.

[0025] The base 110 is fixed on the moving device of the numerical control machine tool, used for installing the support 120 and driving the support 120 to move, facilitating the machining of different positions of the workpiece. The support 120 is circular and has a cavity inside. Limit rings 121 are symmetrically fixed on the outer side surface of the support 120. The ring-shaped part 130 is rotatably sleeved between the opposite limit rings 121, ensuring the stability of the ring-shaped part 130 during rotation.

[0026] The pipe body 140 is integrally fixed on the annular member 130 for installing the rotating member 150. The rotating member 150 includes bearings 151 symmetrically arranged on the inner wall of the pipe body 140, a rotating seat 152 fixed on the inner ring of the bearing 151, and a tool body 153 installed at the end of the rotating seat 152. The outer ring of the bearing 151 is fixed to the inner wall of the pipe body 140, and the inner ring is fixed to the rotating seat 152 to ensure the stability of the rotating seat 152 during rotation. The rotating seat 152 is used to install the tool body 153 and drive the tool body 153 to rotate. The tool body 153 is used to drill the workpiece.

[0027] In addition, the models of the tool bodies 153 on each rotating seat 152 are all different, which is convenient for switching different tool bodies 153 during processing.

[0028] The first driving member 160 is arranged in the inner cavity of the support 120 and includes a first motor 161 movably arranged in the inner cavity of the support 120 and a spline shaft 162 fixed to the shaft of the first motor 161 at its end. The first motor 161 is used to drive the spline shaft 162 to rotate. A spline groove 1521 is formed at the top of the rotating seat 152, and the spline groove 1521 is engaged with the spline shaft 162, so that the first motor 161 can drive the rotating seat 152 to rotate synchronously, that is, drive the tool body 153 to rotate.

[0029] The electric telescopic rod 170 is used to drive the first motor 161 to move up and down, so as to control the spline shaft 162 to disengage from or insert into the spline groove 1521 on the rotating seat 152.

[0030] The second driving member 190 includes a second motor 191 fixed on the base 110 and a gear 192 fixed on the shaft of the second motor 191. The gear 192 meshes with the toothed ring 180. When the second motor 191 rotates, it drives the gear 192 to rotate. The rotation of the toothed ring 180 drives the toothed ring 180 to rotate, and the rotation of the toothed ring 180 drives the annular member 130 to rotate, realizing the switching of different models of tool bodies 153.

[0031] Working principle and usage process of the present utility model: When it is necessary to replace the tool body 153, the electric telescopic rod 170 is activated to drive the first motor 161 to move upward, so that the spline shaft 162 disengages from the spline groove 1521 on the rotating seat 152. Then, the second motor 191 is activated to drive the gear 192 to rotate. The rotation of the gear 192 drives the gear ring 180 to rotate, and the rotation of the gear ring 180 drives the annular member 130 to rotate. The rotation of the annular member 130 rotates the required tool body 153 to the lower part of the first driving member 160. Then, the electric telescopic rod 170 contracts to drive the second motor 191 to move downward. The downward movement of the second motor 191 drives the spline shaft 162 to move downward and engage in the spline groove 1521 on the rotating seat 152 to complete the connection. At this time, the first motor 161 rotates to drive the rotating seat 152 to rotate synchronously, and the rotation of the rotating seat 152 drives the tool body 153 to rotate, and then the operation can be carried out.

[0032] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
