[0031] Example

[0032] like Figures 1-4 As shown,

[0033] A 3D printing device for automotive interior parts includes, from bottom to top, a base 1, a work platform 2, and a positioning stage 3. A three-axis motion module 4 and a print head assembly 5 are mounted on the base 1 outside the work platform 2. A clamping unit is provided on the work platform 2 outside the positioning stage 3.

[0034] 1. The clamping unit includes the left upright 6 on the work platform 2 located to the left of the positioning table 3:

[0035] The left upright 6 is connected to the pressing mechanism 8 below via an elastic connection structure 7. The elastic connection structure 7 includes a connecting rod 16. The left upright 6 and the right upright 11 are both provided with movable cavities 15 for the connecting rod 16 to move freely. The connecting rod 16 passes through the through hole 19 at the bottom of the movable cavity 15 and is connected to the magnetic protrusion 13 below. A limiting block 17 is installed on the top of the connecting rod 16 located in the movable cavity 15. A spring 18 is installed on the connecting rod 16 located between the through hole 19 and the limiting block 17.

[0036] The clamping mechanism 8 includes a clamping base plate 12, magnetic protrusions 13 located at the bottom of the front and rear sides of the clamping base plate 12, and a clamping contact plate 14 located at the middle of the bottom of the clamping base plate 12. A rubber block is bonded to the contact surface at the bottom of the clamping contact plate 14. Alternatively, it can be a block structure with a certain degree of elasticity similar to the rubber block structure described above.

[0037] A left groove 20 for installing the left electromagnet 21 is provided on the positioning platform 3 directly below the magnetic protrusion 13 at the bottom of the left upright 6. The magnetic protrusion 13 can be embedded into the left groove 20 after being attracted by the left electromagnet 21.

[0038] 2. The clamping unit includes the right upright frame 11 located on the work platform 2 to the right of the positioning table 3:

[0039] The right upright 11 is connected to the pressing mechanism 8 below via an elastic connection structure 7. The elastic connection structure 7 includes a connecting rod 16. The left upright 6 and the right upright 11 are both provided with movable cavities 15 for the connecting rod 16 to move freely. The connecting rod 16 passes through the through hole 19 at the bottom of the movable cavity 15 and is connected to the magnetic protrusion 13 below. A limiting block 17 is installed on the top of the connecting rod 16 located in the movable cavity 15. A spring 18 is installed on the connecting rod 16 located between the through hole 19 and the limiting block 17.

[0040] The clamping mechanism 8 includes a clamping base plate 12, magnetic protrusions 13 located at the bottom of the front and rear sides of the clamping base plate 12, and a clamping contact plate 14 located at the middle of the bottom of the clamping base plate 12. A rubber block is bonded to the contact surface at the bottom of the clamping contact plate 14. Alternatively, it can be a block structure with a certain degree of elasticity similar to the rubber block structure described above.

[0041] A push cylinder 9 is installed on the work platform 2 on one side of the right upright 11. The drive end of the push cylinder 9 drives the right upright 11 to move in the left and right direction via the push connecting frame 10. The right upright 11 is mounted on the work platform 2 by a slider guide rail assembly distributed along the left and right direction.

[0042] A right groove 23 for mounting a right electromagnet 24 is provided on the positioning platform 3 directly below the magnetic protrusion 13 at the bottom of the right upright 11. The magnetic protrusion 13 can be embedded into the right groove 23 after being attracted by the right electromagnet 24. The right groove 23 is distributed along the left and right direction, and the right electromagnet 24 inside is also arranged in the same way. Therefore, the clamping mechanism 8 at the right upright 11 can be adjusted to a certain extent in the left and right direction, thus making it suitable for processing products of different widths and improving the applicability of product processing.

[0043] In particular, a wire groove 22 is provided in the positioning platform 3 on one side of the bottom of the left groove 20 and the right groove 23. The wire groove 22 is used for cables and other things connected to the electromagnet.

[0044] Brief description of the working process of this utility model:

[0045] The clamping mechanisms 8 at the left upright 6 and the right upright 11 operate in largely the same way, the difference being that the clamping mechanism 8 at the right upright 11 can move a certain distance in the left and right directions. Therefore, the following explanation will use the left upright 6 as an example.

[0046] When product clamping is not required, the left electromagnet 21 is not energized, and the spring 18 is in a relaxed state, lifting the limiting block 17 and causing the magnetic protrusion 13 to be positioned above the left groove 20 via the connecting rod 16. When product clamping is required, the left electromagnet 21 is energized, attracting the magnetic protrusion 13 to move downwards towards the left groove 20 and to conform to the left electromagnet 21. At this time, the spring 18 is in a compressed state, and then the clamping contact plate 14 located inside the clamping base plate 12 contacts and clamps the two sides of the product below. This clamping method ensures that the clamping contact plate 14 does not directly drive the product to clamp, which can reduce clamping damage to the product to a certain extent.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.
