The bathtub body cutting device may also include: a supporting mechanism 3, an inner support clamping mechanism 4, and a cutting mechanism 5.

[0059] Specifically, by Figure 1 and Figure 2 As shown, the supporting mechanism 3 is fixed on the cutting platform 2, and is used for supporting the cylinder body 1 to be cut so that there is a gap between the cylinder body 1 to be cut and the cutting platform 2, and is also used for driving the cylinder body 1 to be cut to rotate.

[0060] Further, by Figure 1 and Figure 2 As shown, the support mechanism 3 may include: a support plate 32 and a servo motor 31. The support plate 32 is rotatably installed on the cutting platform 2. The servo motor 31 is fixed to the bottom surface of the cutting platform 2 to drive the support plate 32 to rotate. When in use, the support plate 32 is used to support the cylinder body 1 to be cut, so that there is a gap between the cylinder body 1 to be cut and the cutting platform 2, leaving enough cutting space. When cutting, the servo motor 31 can be started to drive the support plate 32 to rotate, change the direction of the cylinder body 1 to be cut, and make the cutting position close to the cutting mechanism 5, which is more conducive to cutting.

[0061] Specifically, by Figure 1 and Figure 3 As shown, the inner support clamping mechanism 4 is movably arranged above the cutting platform 2, and is used to support the cylinder body 1 to be cut from the inside.

[0062] Further, by Figure 1 and Figure 3 As shown, the internal support clamping mechanism 4 may include: a lifting plate 41 and an internal support clamping assembly 42. The lifting plate 41 is located above the cutting platform 2 and has the freedom to move in the vertical direction. Multiple groups of internal support clamping assemblies 42 are fixed to the bottom surface of the lifting plate 41 and are used to support the cylinder body 1 to be cut from the inside.

[0064] Multiple groups of inner support clamping assemblies 42 are independently controlled and can be used to support bathtub bodies of different sizes and shapes. If the size and shape of the bathtub body are not taken into consideration, the inner support clamping assemblies 42 can also be driven synchronously to reduce the power source. For example, two groups of symmetrical inner support clamping assemblies 42 are driven by the same bidirectional screw rod and motor, so that the two groups of inner support clamping assemblies 42 can move in opposite directions at the same time.

[0065] Optionally, by Figure 1 and Figure 3As shown, the internal support clamping mechanism 4 also includes: a top plate 9 and a vertical cylinder 44.

The third servo motor 59 is fixed on the second fixed plate 511 to drive the first threaded rod 58 to rotate. When cutting, the third servo motor 59 is first started to drive the first threaded rod 58 to rotate, so that the fixed frame 52 moves under the action of threaded engagement, so that the grinding wheel 54 approaches the cutting position, and then the driving motor 55 is started to drive the grinding wheel 54 to rotate to complete the grinding and cutting. If necessary, the second servo motor 56 can be started to drive the U-shaped frame 53 to rotate, adjust the angle of the grinding wheel 54, and ensure that the grinding wheel 54 corresponds reliably to the cutting position.

[0069] Further, by Figure 1 and Figure 5As shown, it also includes a mobile tooling 6, and the mobile tooling 6 includes: a frame 61, a threaded column 62 and a No. 4 servo motor 63.

[0070] Optionally, by Figure 1 and Figure 5 As shown, a guide column 64 penetrating the base 51 is fixed in the frame 61 for guiding the base 51 to improve the stability of the base 51 .

[0071] Further, by Figure 1 and Figure 5 As shown, it also includes a driving mechanism 7, which is fixed on the cutting platform 2 and is used to drive the mobile tooling 6 to move, and the driving mechanism 7 includes: a No. 3 fixed plate 72, a No. 2 threaded rod 73 and a No. 5 servo motor 71, the two No. 3 fixed plates 72 are symmetrically fixed on the cutting platform 2, the No. 2 threaded rod 73 is rotatably installed between the two No. 3 fixed plates 72, and the No. 2 threaded rod 73 penetrates the frame 61 and is connected to the frame 61 by threaded engagement, the No. 5 servo motor 71 is fixed on the No. 3 fixed plate 72 and is used to drive the No. 2 threaded rod 73 to rotate, and the No. 5 servo motor 71 is started to drive the No. 2 threaded rod 73 to rotate, so that the mobile tooling 6 moves in the horizontal direction under the action of the threaded engagement, and drives the cutting mechanism 5 to move in the horizontal direction, so as to facilitate cutting at different positions of the cutting cylinder 1.

[0072] It should be noted that the direction proposed in this embodiment is only used to explain the direction of the cutting device in the accompanying drawings, and is not used to limit the present invention. Theoretically, on the premise of being able to complete this scheme, it can also be other directions. For example, the cylinder body 1 to be cut can also be placed in a vertical direction, and the corresponding moving directions of other mechanisms will also change. For example, when the cylinder body 1 to be cut is placed in a vertical direction, the internal support clamping mechanism 4 should move horizontally.

[0073] Working principle and use process of the utility model: When using the bathtub body cutting device of the utility model, first place the body 1 to be cut on the supporting plate 32, then start the vertical cylinder 44, and push the lifting plate 41 downward through the piston rod of the vertical cylinder 44 until the inner support clamping assembly 42 enters the body 1 to be cut, then start the horizontal cylinder 425, and use the piston rod of the horizontal cylinder 425 to push the moving plate 422 to move outward, and absorb and hold the body 1 to be cut tightly through the suction cup 424 to ensure the stability of the body 1 to be cut;

[0074] The fourth servo motor 63 is started to drive the threaded column 62 to rotate. Under the action of the thread rotation, the base 51 moves in the vertical direction to change the height of the cutting mechanism 5 so that the cutting mechanism 5 corresponds to the top edge or the bottom edge of the cylinder body 1 to be cut;

[0075] Start the No. 3 servo motor 59 to drive the No. 1 threaded rod 58 to rotate, so that the fixed frame 52 moves under the action of the thread rotation, so that the grinding wheel 54 is close to the cutting position, and then start the driving motor 55 to drive the grinding wheel 54 to rotate to complete the grinding and cutting. If necessary, start the No. 2 servo motor 56 to drive the U-shaped frame 53 to rotate and adjust the angle of the grinding wheel 54 to ensure that the grinding wheel 54 corresponds reliably to the cutting position;

[0076] After the cutting is completed, the No. 1 servo motor 31 can be started to drive the support plate 32 to rotate, so that the cylinder body 1 to be cut rotates. Due to the presence of the bearing 43, the lifting plate 41 will also rotate when the cylinder body 1 to be cut rotates, adjusting the direction of the cylinder body 1 to be cut so that other cutting positions are sufficiently close to the cutting mechanism 5, which is more conducive to cutting.
