Description

Technical Field

[0001] This utility model belongs to the technical field, and in particular relates to a burr trimming device for producing automotive interior parts. Background Technology

[0002] Automotive interior refers to all the decorative and functional components inside a car. These components not only serve an aesthetic purpose but also directly affect the comfort and driving experience of the car owner. Raw edges are usually left by irregular parts or excess materials during the processing of fabrics or leather. If these raw edges are not trimmed, they will affect the overall appearance of the interior parts, making them look rough and unrefined, and even affecting the consumer's overall impression of the car. By trimming the raw edges, the surface of the interior parts can be made smoother and the visual appeal can be enhanced.

[0003] However, existing burr trimming devices are not convenient for laying interior parts flat on the workbench during use. The interior parts will have wrinkles, warps or local bulges on the workbench. The trimming tool is difficult to accurately fit the edge of the part, which leads to incomplete burr trimming, uneven edges, or even accidental trimming of normal parts, affecting the dimensional accuracy and appearance quality of the parts. Utility Model Content

[0004] The purpose of this utility model is to provide a burr trimming device for producing automotive interior parts. By setting up a flattening mechanism, it solves the problem that existing burr trimming devices are not convenient to flatten the interior parts on the worktable during use. The interior parts will have wrinkles, warping or local bulges on the worktable. The trimming tool is difficult to accurately fit the edge of the part, which leads to incomplete burr trimming, uneven edges, or even accidental trimming of normal parts, affecting the dimensional accuracy and appearance quality of the parts.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a burr trimming device for producing automotive interior parts, including a workbench, on which a flattening mechanism and a cutting mechanism are provided;

[0007] The bottom of the workbench is fixedly connected to two support legs, the top of the workbench is fixedly connected to two support frames, the top of the two support frames is fixedly connected to a support frame, the leveling mechanism includes a rectangular plate disposed below the support frame, and the cutting mechanism includes an electric telescopic rod fixedly connected to the top of the support frame, the output shaft of the electric telescopic rod passes through the support frame and is fixedly connected to the rectangular plate.

[0008] Furthermore, connecting rods are hinged to both the front and rear sides of the rectangular plate, and two support frames are hinged to the side of several connecting rods away from the rectangular plate. Rotating shafts are rotatably connected to the inner walls of the two support frames, and flattening rollers are fixedly connected to the outer walls of the two rotating shafts.

[0009] Furthermore, several support rods are fixedly connected to the bottom of each of the two support frames, and several L-shaped guide blocks are fixedly connected to the side of the several support rods away from the support frame.

[0010] Furthermore, each of the L-shaped guide blocks has a guide groove on the side near the two support frames three. The front and rear sides of the two support frames three are fixedly connected to sliders. The sides of the sliders away from the two support frames three extend into the guide grooves respectively. The sliders are slidably connected to the guide grooves respectively.

[0011] Furthermore, an L-shaped connecting rod is fixedly connected to the bottom of the rectangular plate, and a cutting blade is fixedly connected to the side of the L-shaped connecting rod away from the rectangular plate.

[0012] Furthermore, two sliding rods are fixedly connected to the bottom of the support frame located on the front side, and connecting blocks are slidably connected to the outer walls of the two sliding rods. The front sides of the two connecting blocks are fixedly connected to the cutting blade.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting up a flattening mechanism, when the rectangular plate moves downward, the support frame three will also drive the slider and flattening roller to move downward. When the flattening roller descends to contact the interior trim, the slider also descends to the bottom of the L-shaped guide block. As the electric telescopic rod continues to extend, the two support frames three, under the connection of the connecting rod, will cooperate with the guide groove and the slider to drive the two flattening rollers away from each other. During this process, due to the setting of the rotating shaft, the two flattening rollers will roll when they move away from each other, flattening the interior trim. When the flattening roller rolls roll, they can apply pressure evenly to the surface of the interior trim. Through mechanical external force, wrinkles, warps or local protrusions are flattened, providing a flat processing reference surface for trimming burrs. After the interior trim is flattened, the cutting blade can fit more closely to the real edge of the part, avoiding trimming deviation caused by uneven surface, ensuring thorough removal of burrs and neat edges, and ensuring the dimensional accuracy and appearance quality of the parts.

[0015] 2. By setting up a cutting mechanism, when it is necessary to remove burrs from interior trim parts, the electric telescopic rod on support frame two can be activated to extend it. The electric telescopic rod drives the L-shaped connecting rod downward through the rectangular plate, which in turn drives the cutting blade downward until the cutting of the interior trim parts is completed. During the downward movement of the cutting blade, the sliding rod and the connecting block will cooperate to limit the cutting blade, ensuring that the cutting blade moves downward stably. This can prevent the cutting blade from deviating or shaking during the downward movement, so that the blade can contact the burrs of the interior trim parts along the predetermined trajectory, ensuring that the trimmed edges are neat and the dimensions are uniform. This avoids over-cutting or burr residue caused by the instability of the cutting blade, thus ensuring the processing quality.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0026] Please see Figure 1-5 As shown, this utility model is a burr trimming device for producing automotive interior parts, including a workbench 1, a flattening mechanism 2 and a cutting mechanism 3 on the workbench 1, two support legs 101 fixedly connected to the bottom of the workbench 1, two support frames 102 fixedly connected to the top of the workbench 1, and support frames 103 fixedly connected to the top of the two support frames 102.

[0027] The leveling mechanism 2 includes a rectangular plate 211 positioned below support frame 2 103. Connecting rods 212 are hinged to both the front and rear sides of the rectangular plate 211. Two support frames 3 213 are hinged to the sides of the connecting rods 212 away from the rectangular plate 211. Rotating shafts 214 are rotatably connected to the inner walls of both support frames 3 213. Leveling rollers 215 are fixedly connected to the outer walls of both rotating shafts 214. Several support rods 216 are fixedly connected to the bottom of both support frames 1 102. Several L-shaped guide blocks 217 are fixedly connected to the sides of the support rods 216 away from the support frames 1 102. Guides are provided on the sides of the L-shaped guide blocks 217 near the two support frames 3 213. Sliders 219 are fixedly connected to the front and rear sides of the groove 218 and the two support frames 213. Several slides 219 extend into several guide grooves 218 from the side away from the two support frames 213. Several slides 219 are slidably connected to several guide grooves 218. By setting the flattening mechanism 2, the flattening roller 215 can apply pressure evenly to the surface of the interior trim when it rolls. The mechanical external force flattens the wrinkles, warps or local protrusions, providing a flat processing reference surface for trimming the burrs. After the interior trim is flattened, the cutting blade 313 can fit the real edge of the part more closely, avoiding trimming deviation caused by uneven surface, ensuring thorough removal of burrs and neat edges, and ensuring the dimensional accuracy and appearance quality of the part.

[0028] The cutting mechanism 3 includes an electric telescopic rod 311 fixedly connected to the top of the support frame 2 103. The output shaft of the electric telescopic rod 311 passes through the support frame 2 103 and is fixedly connected to a rectangular plate 211. An L-shaped connecting rod 312 is fixedly connected to the bottom of the rectangular plate 211. A cutting blade 313 is fixedly connected to the side of the L-shaped connecting rod 312 away from the rectangular plate 211. Two sliding rods 314 are fixedly connected to the bottom of the support frame 1 102 located at the front. Connecting blocks 315 are slidably connected to the outer walls of the two sliding rods 314. The front sides of the two connecting blocks 315 are fixedly connected to the cutting blade 313. By setting the cutting mechanism 3, the cutting blade 313 can be prevented from shifting or shaking during the downward movement, so that the blade can contact the rough edges of the interior parts along a predetermined trajectory, ensuring that the trimmed edges are neat and the dimensions are uniform. This avoids over-cutting or rough edge residue caused by the instability of the cutting blade 313, thus ensuring the processing quality.

[0029] A specific application of this embodiment is as follows: In use, the interior trimming parts to be trimmed are first placed on the workbench 1. When it is necessary to remove the burrs from the interior trimming parts, the electric telescopic rod 311 on the support frame 2 103 can be activated to extend it. The electric telescopic rod 311 drives the L-shaped connecting rod 312 to move downward through the rectangular plate 211, which in turn drives the cutting blade 313 to move downward until the cutting of the interior trimming parts is completed. During the downward movement of the cutting blade 313, the sliding rod 314 and the connecting block 315 cooperate with each other to limit the cutting blade 313, ensuring that the cutting blade 313 moves downward stably. As the rectangular plate 211 moves downward, the support frame 213 also moves the slider 219 and the flattening roller 215 downward. When the flattening roller 215 descends to contact the interior trim, the slider 219 also descends to the bottom of the L-shaped guide block 217. As the electric telescopic rod 311 continues to extend, the two support frames 213, connected by the connecting rod 212, work together with the guide groove 218 and the slider 219 to move the two flattening rollers 215 away from each other. During this process, due to the setting of the rotating shaft 214, the two flattening rollers 215 will roll when they move away from each other, flattening the interior trim.
