The cutting machine for automobile interior part processing in the prior art has fine and efficient working process. Specifically, first, the required cutting interior pattern is accurately designed and output by computer system. Then, the mechanical arm as the core control component accurately guides the electric reciprocating cutter to cut according to the preset pattern. This process not only significantly improves the cutting accuracy, but also greatly improves the production efficiency, becoming an indispensable key technology link in modern automobile interior part manufacturing.

[0003] The patent with Chinese publication number CN221371628U discloses a cutting machine for automobile interior part processing, which comprises a connecting rod, an electric reciprocating cutter connected and fixed at one end of the connecting rod away from the mechanical arm, a wire insertion hole for inserting wires on the upper surface of the connecting rod, an adjusting piece connected and fixed on the annular surface of the connecting rod, a telescopic piece connected and fixed at one end of the adjusting piece away from the connecting rod, a support plate connected and fixed at both ends of the telescopic piece, a groove opened on the lower surface of the support plate, a plurality of first U-shaped frames connected and fixed on the top of the groove, a first rotating rod connected and fixed on the opposite two sides in the first U-shaped frame, a roller arranged in the first U-shaped frame, and the first rotating rod away from the first U-shaped frame is rotationally connected with the roller. The cutting machine can avoid the problem of uneven cutting surface or yarn pulling of the textile material caused by the softness of the textile material when the electric reciprocating cutter cuts the textile material.

[0004] When the cutting machine in the above patent document is used, the connecting rod drives the support plate to move in one direction through the L-shaped rod, so that the roller installed at the bottom moves on the surface of the material, thereby preventing the material from wrinkling during cutting. However, the cutting mechanism in the above needs to move according to the shape of the automobile ornament to make the cut material meet the design requirements. Since the support plate can only drive the roller to move in one direction, the roller is prone to cause the material to wrinkle or displace when moving, for example: the support plate driven by the L-shaped rod can only move in the X-axis direction, when the L-shaped rod drives the support plate to move in the Y-axis direction for cutting, the roller at the bottom of the support plate rubs against the surface of the material, thereby causing the material to wrinkle or displace. Therefore, a cutting mechanism for automobile interior part processing is proposed. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0030] In order to further understand the characteristics, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments

[0031] Referring to Figures 1-8 , a cutting mechanism for automobile interior part processing, comprising a cutting device 1, a pressing mechanism 3 arranged at the bottom of the cutting device 1 and a moving frame 5 capable of moving longitudinally arranged outside the pressing mechanism 3, the pressing mechanism 3 comprises a mounting seat 31 fixed to the bottom of the cutting device 1, an rotating seat 32 capable of rotating along the central axis thereof is arranged outside the mounting seat 31, and a toothed belt 321 is arranged at the top of the outer wall of the rotating seat 32;

[0032] A servo motor 2 is arranged on the side of the cutting device 1, and a driving gear 21 capable of meshing with the toothed belt 321 is arranged on the output end of the servo motor 2;

[0033] The bottom of the moving frame 5 is provided with a pressing frame 6 capable of moving longitudinally for pressing the material.

[0034] When the servo motor 2 is started, the servo motor 2 can drive the driving gear 21 on the output end thereof to rotate, and the driving gear 21 rotates at the same time to drive the rotating seat 32 to rotate synchronously along the central axis of the mounting seat 31 through the toothed belt 321 meshing therewith. When the rotating seat 32 rotates, the rotating seat 32 drives the moving frame 5 outside to rotate around the central axis of the mounting seat 31, so that the angle of the moving frame 5 can be adjusted.

[0035] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , and Figure 6 , an mounting sleeve 51 capable of adapting to the rotating seat 32 is arranged at the center of the top of the moving frame 5, and limiting grooves 52 for mounting the pressing frame 6 are symmetrically arranged at the bottom of the moving frame 5.

[0036] The moving frame 5 is installed on the outside of the rotating seat 32 through the installation sleeve 51 installed at the center of the top of the moving frame 5, and the pressing frame 6 is installed in the installation hole 53 opened at the bottom of the moving frame 5. When the cutting device 1 drives the installation seat 31 and the rotating seat 32 to move downward, the moving frame 5 installed on the outside of the rotating seat 32 moves downward synchronously, so that the bottom of the pressing frame 6 in the limiting groove 52 is in contact with the upper surface of the material. At this time, the reaction force of the material pushes the moving frame 5 to move upward along the central axis of the rotating seat 32 through the installation sleeve 51.

[0037] As shown in Figure 4 and Figure 6 , the two sides of the top of the moving frame 5 near the installation sleeve 51 are longitudinally provided with installation holes 53, and the installation holes 53 are internally provided with threaded rods 7 capable of driving the longitudinal movement of the pressing frame 6, and the pressing frame 6 is threadedly connected with the threaded rods 7.

[0038] By longitudinally installing the threaded rods 7 on the top of the moving frame 5 near the two sides of the installation sleeve 51, the threaded rods 7 can extend into the installation holes 53 and threadedly cooperate with the pressing frame 6. When the threaded rods 7 are rotated, the threaded rods 7 can drive the pressing frame 6 installed on the outside of the threaded rods 7 to move longitudinally in the installation holes 53, so as to adjust the height of the pressing frame 6.

[0039] As shown in Figure 7 , the bottom end of the pressing frame 6 is provided with an external threaded column 64, the bottom end of the external threaded column 64 is provided with an installation groove 61, and the installation groove 61 is internally provided with a roller 62 capable of rolling.

[0040] By installing the roller 62 in the installation groove 61, when the pressing frame 6 moves downward, the bottom of the roller 62 installed at the bottom of the pressing frame 6 is in contact with the surface of the material. When the pressing frame 6 moves, the pressing frame 6 can drive the roller 62 at the bottom to walk on the surface of the material.

[0041] As shown in Figure 7 , the bottom of the roller 62 is provided with a limiting sleeve 63 for preventing the roller 62 from falling off, and the limiting sleeve 63 is threadedly connected with the external threaded column 64.

[0042] To avoid the roller 62 from falling off from the installation groove 61, the limiting sleeve 63 is installed on the outside of the external threaded column 64, so that the limiting sleeve 63 can lift the roller 62, effectively avoiding the problem of the roller 62 falling off.

[0043] As shown in Figure 4 and Figure 5 , the bottom end of the rotating seat 32 is fixedly provided with an anti-falling ring 33 for preventing the moving frame 5 from falling off, and the top of the moving frame 5 is provided with a return spring 4 which is sleeved on the outside of the rotating seat 32 and is used to push the moving frame 5 to return.

[0044] In order to prevent the mounting sleeve 51 from falling off the rotating seat 32, a falling prevention ring 33 is fixedly installed at the bottom end of the rotating seat 32. When the moving frame 5 moves downward along the central axis of the rotating seat 32, the lower end surface of the mounting sleeve 51 arranged at the center of the top of the moving frame 5 gradually approaches the falling prevention ring 33. When the lower end surface of the mounting sleeve 51 approaches the falling prevention ring 33, the mounting sleeve 51 is blocked by the falling prevention ring 33 and then stops moving downward, effectively avoiding the moving frame 5 from falling off the rotating seat 32.

[0045] Referring to Figure 8 As shown in the figure, the outer wall of the mounting seat 31 is horizontally provided with an annular limiting sliding rail 311 for limiting;

[0046] The inner wall of the top of the rotating seat 32 is provided with an annular sliding groove 322 capable of slidingly cooperating with the annular limiting sliding rail 311.

[0047] In order to ensure the stability of the rotating seat 32, the rotating seat 32 is installed outside the mounting seat 31, so that the annular sliding groove 322 arranged inside the rotating seat 32 and the annular limiting sliding rail 311 arranged on the outer wall of the mounting seat 31 slideably cooperate. When the rotating seat 32 rotates, the rotating seat 32 can slide along the annular limiting sliding rail 311 through the annular sliding groove 322, which not only ensures that the rotating seat 32 can normally rotate, but also avoids the rotating seat 32 from falling off the mounting seat 31 by the cooperation between the annular sliding groove 322 and the annular limiting sliding rail 311, effectively ensuring the stability of the rotating seat 32.

[0048] Referring to Figure 1 and Figure 2 As shown in the figure, the bottom of the cutting device 1 is provided with a rotating shaft 11 capable of rotating;

[0049] The inside of the mounting seat 31 is provided with a bearing 34, and the bearing 34 is sleeved outside the rotating shaft 11.

[0050] By arranging the bearing 34 inside the mounting seat 31 and sleeving the bearing 34 outside the rotating shaft 11, the central axis of the mounting seat 31 can always coincide with the central axis of the rotating shaft 11, effectively avoiding the collision between the inner wall of the mounting seat 31 and the rotating shaft 11 caused by the deviation of the mounting seat 31.

[0051] The above embodiments only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
