[0002] Plastic components play a vital role in modern automobile manufacturing. They reduce vehicle weight, improve fuel efficiency, and offer excellent corrosion resistance and molding properties. Common automotive plastic components include: bumpers, headlight housings, exterior trim, dashboards, seat components, air conditioning panels, battery housings, as well as pipes and connectors.

[0003] In the production and processing of automotive plastic parts, cutting devices are required for cutting. In order to ensure the accuracy of cutting, positioning devices are needed to clamp and position the plastic parts.

[0004] However, the existing cutting and positioning devices operate with two independent power systems, which increases the complexity of the entire system. The lack of proper synchronization or coordination between the two systems can lead to inaccurate positioning and cutting operations or errors. This increased system complexity also makes troubleshooting and maintenance more difficult. Utility Model Content

A pressure spring is provided on the outer side of the cylindrical rod, and the pressure spring is located between the fixed plate and the positioning plate.

[0007] As a preferred embodiment of this utility model, the outer sides of the transmission wheel are provided with second annular teeth, and the middle of the outer side of the transmission wheel is provided with first annular teeth.

[0008] As a preferred embodiment of this utility model, positioning rods are fixedly connected to both the front and back sides of the top of the lifting plate, and the positioning rods are movably sleeved with the top of the fixed frame.

[0009] As a preferred embodiment of this utility model, the front and back of the fixing frame are provided with sliding grooves, and the top of the inner wall of the sliding groove is provided with a trapezoidal groove, and the sliding groove is slidably sleeved with the movable plate.

[0010] As a preferred technical solution of this utility model, a rectangular through groove is provided in the middle of the top of the movable plate, and the rectangular through groove is slidably sleeved with the lifting rack.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6As shown, this utility model provides a cutting and positioning device for automotive plastic parts, including a transmission table 1. A fixed frame 101 is fixedly connected to the top of the transmission table 1. A lifting assembly 2 is installed on the top of the fixed frame 101, and a cutting mechanism 3 is installed at the bottom of the lifting assembly 2. A transmission assembly 4 is installed on both the front and back of the top of the transmission table 1. The lifting assembly 2 includes a cylinder 201 fixedly connected to the top of the fixed frame 101. A lifting plate 202 is fixedly connected to the bottom of the piston rod of the cylinder 201. The cutting mechanism 3 is installed in the middle of the bottom of the lifting plate 202. A lifting rack 203 is fixedly connected to both the front and back of the bottom of the lifting plate 202. The transmission assembly 4 includes a movable plate 401 and a fixed block 405 fixedly connected to the top of the transmission table 1. Both sides of the bottom of the movable plate 401 are provided with meshing teeth 404. The inner side of the fixed block 405 is movably sleeved with a rotating rod 406, and the outer side of the rotating rod 406 is fixedly sleeved with a transmission wheel 407. The two movable plates 401 are each installed with a positioning component 5 at their close ends. The positioning component 5 includes a fixed plate 501. Both sides of the surface of the fixed plate 501 are movably sleeved with cylindrical rods 502. One end of the cylindrical rod 502 is fixedly connected with a stop block 503, and the other end of the cylindrical rod 502 is fixedly connected with a positioning plate 504. A pressure spring 505 is provided on the outer side of the cylindrical rod 502. The pressure spring 505 is located between the fixed plate 501 and the positioning plate 504. A rectangular through hole is opened on the top of the transmission table 1. The rectangular through hole is adapted to the lifting rack 203.

[0025] In this embodiment, when the cutting mechanism 3 cuts downwards, the lifting plate 202 drives the lifting rack 203 to move vertically downwards. Under the meshing action of the lifting rack 203 and the first ring tooth 471, the transmission wheel 407 rotates. Under the meshing action of the second ring tooth 472 and the meshing tooth 404, the movable plate 401 drives the fixed plate 501 to move closer to each other along the inner side of the slide groove 111. As a result, the pressure spring 505 is compressed, and the positioning plate 504 can increase the pressure on the surface of the plastic part, thereby achieving the positioning of the plastic part, avoiding deviation during the cutting process, and thus improving the cutting accuracy.

[0026] The transmission wheel 407 has two second ring teeth 472 on both sides of its outer side and a first ring tooth 471 in the middle of its outer side. The second ring teeth 472 mesh with the meshing teeth 404, and the first ring teeth 471 mesh with the lifting rack 203.

[0027] The lifting plate 202 has a positioning rod 204 fixedly connected to both the front and back sides of its top, and the positioning rod 204 is movably sleeved with the top of the fixed frame 101.

[0028] The positioning rod 204 can position the lifting plate 202 to prevent it from shifting or tilting during the process of the cylinder 201 driving the lifting plate 202 to rise and fall.

[0029] The fixed frame 101 has a sliding groove 111 on both the front and back sides. The top of the inner wall of the sliding groove 111 has a trapezoidal groove 112. The sliding groove 111 is slidably sleeved with the movable plate 401. The middle of the top of the movable plate 401 has a rectangular through groove 403. The rectangular through groove 403 is slidably sleeved with the lifting rack 203. Trapezoidal strips 402 are fixedly connected to both sides of the top of the movable plate 401. The trapezoidal strips 402 are slidably sleeved with the trapezoidal grooves 112.

[0030] When the drive wheel 407 rotates, the movable plate 401 slides back and forth along the inner side of the slide groove 111. The cooperation between the trapezoidal bar 402 and the trapezoidal groove 112 can further position the movable plate 401, so that the movable plate 401 can always maintain horizontal back and forth movement and avoid tilting or offset. Due to the setting of the rectangular through groove 403, the lifting rack 203 will not interfere with the movable plate 401 during the lifting process.

[0031] Working principle and usage process of this utility model:

[0032] When the cutting mechanism 3 cuts downwards, the lifting plate 202 drives the lifting rack 203 to move vertically downwards. Under the meshing action of the lifting rack 203 and the first ring tooth 471, the transmission wheel 407 rotates. Under the meshing action of the second ring tooth 472 and the meshing tooth 404, the movable plate 401 drives the fixed plate 501 to move closer to each other along the inner side of the slide groove 111. As a result, the pressure spring 505 is compressed, and the positioning plate 504 can increase the pressure on the surface of the plastic part, realize the positioning of the plastic part, avoid deviation during the cutting process, and thus improve the cutting accuracy.

[0033] When the drive wheel 407 rotates, the movable plate 401 slides back and forth along the inner side of the slide groove 111. The cooperation between the trapezoidal bar 402 and the trapezoidal groove 112 can further position the movable plate 401, so that the movable plate 401 can always maintain horizontal back and forth movement and avoid tilting or offset. Due to the setting of the rectangular through groove 403, the lifting rack 203 will not interfere with the movable plate 401 during the lifting process.
