Description

A cutting device for processing decorative parts for electric vehicle dashboard covers Technical Field

[0001] This utility model belongs to the field of electric vehicle parts processing technology, specifically relating to a cutting device for processing electric vehicle dashboard decorative parts. Background Technology

[0002] The cutting device for processing electric vehicle dashboard trim parts is a tool specifically designed for the precise cutting of dashboard trim parts. This device is typically equipped with high-precision cutting tools and an automated control system, enabling precise cutting of trim parts according to design drawings. The cutting device ensures smooth, burr-free edges during the cutting process, avoiding adverse effects on appearance and quality. The device is compact, easy to operate, and can improve production efficiency while reducing the risks associated with manual operation.

[0003] Chinese patent CN116141400A discloses a cutting device for processing decorative parts for electric vehicle instrument panels. The device includes a trapezoidal base, a positioning and lifting mechanism on the left side of the base, a processing table on top of the positioning and lifting mechanism, an offset correction mechanism on the left side of the processing table, cylinders symmetrically arranged on the top wall of the processing table on both sides of the offset correction mechanism, and a burr removal mechanism located at the output end of each cylinder on the top right side of the processing table. This invention achieves positioning correction during the cutting process of the plastic instrument panel decorative parts through the offset correction mechanism. Simultaneously, by using an electromagnet and a correction rod to pull a limiting bottom rod, offset correction is achieved during the cutting process of the bottom of the plastic instrument panel. This ensures that the cutter always acts perpendicularly to the side wall of the plastic instrument panel, thereby guaranteeing the flatness of the cut end face and improving the processing quality of the plastic instrument panel decorative parts.

[0004] However, the current cutting device has the following problems: when the existing cutting device cuts the workpiece with a pressing knife, the whole device is not vertically pressed and fixed during the conveying process, which causes the edge to curl up during the cutting, resulting in non-standard workpiece cut. Therefore, we propose a cutting device for processing electric vehicle instrument cover decorative parts. Summary of the Invention

[0005] The purpose of this utility model is to provide a cutting device for processing decorative parts of electric vehicle instrument panels, which can solve the problem that existing cutting devices in related technologies cause warping and non-standard workpiece cuts when cutting workpieces because the device as a whole is not vertically pressed and fixed during the conveying process.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A cutting device for processing decorative parts for electric vehicle instrument panels includes a cutting table. A cutting device is fixedly connected to the inner wall of the cutting table. An anti-warping device is provided on the inner wall of the cutting table. The anti-warping device includes two bidirectional threaded rods. The bottom of the two bidirectional threaded rods is rotatably connected to the inner wall of the cutting table. A torsion block is fixedly connected to the top of the bidirectional threaded rods. Two movable plates are threadedly connected to opposite circumferential surfaces of the bidirectional threaded rods. A drive assembly is provided on the side of each of the two movable plates. A limit rod is fixedly connected to the inner wall of the cutting table.

[0008] The drive assembly includes a motor, the side of which is fixedly connected to the side of the moving plate. The output shaft of the motor is fixedly connected to a rotating shaft. A rotating rod is rotatably connected to the side of the moving plate. A track is connected between the rotating rod and the rotating shaft, and the track is the drive end of the drive assembly.

[0009] The limiting rod is in contact with the moving plate, and the inner diameter of the groove of the moving plate is equal to the outer diameter of the limiting rod.

[0010] A cleaning device is provided on the side of the moving plate. The cleaning device includes a connecting block. The side of the connecting block is fixedly connected to the side of the moving plate. A connecting shaft is fixedly connected to the end of the rotating rod away from the track. A rotating shaft is rotatably connected to the side of the connecting block. A conveyor belt is connected between the connecting shaft and the rotating shaft. A cleaning roller is fixedly connected to the circumferential surface of the rotating shaft.

[0011] The cleaning roller is in contact with the track, and there is a gap between the track and the moving plate.

[0012] The cleaning roller is made of a highly wear-resistant and thermally conductive material, and the connecting block and the moving plate are flush.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention utilizes an anti-warping device to coordinate the bidirectional threaded rod, torsion block, moving plate, motor, rotating shaft, track, limiting rod, and rotating rod. The workpiece is placed between two tracks, and the operator twists the torsion block. The rotation of the torsion block drives the bidirectional threaded rod, which in turn causes the moving plate to move towards the workpiece under the constraint of the limiting rod, thus clamping the workpiece. This avoids the warping that occurs in existing cutting devices when cutting workpieces with a pressure cutter, where the entire device is not vertically pressed and fixed during transport, resulting in non-standard cuts. Simultaneously, the movement of the moving plate drives the movement of the motor. Starting the motor causes its output shaft to rotate, which in turn drives the rotating shaft, which in turn drives the track. The rotation of the track prevents insufficient clamping force from forming on the clamping surface after prolonged use.

[0015] This utility model, through the setting of the cleaning device, enables the connecting block, connecting shaft, rotating shaft, track, and cleaning roller to cooperate. At the same time, the movement of the moving plate drives the movement of the connecting block, the rotation of the track drives the rotation of the rotating rod, the rotation of the rotating rod drives the rotation of the connecting shaft, the rotation of the connecting shaft drives the rotation of the conveyor belt, the rotation of the transmission belt drives the rotation of the rotating shaft, and the rotation of the rotating shaft drives the rotation of the cleaning roller. The rotation of the cleaning roller ensures that the device will not be crushed by the cut debris during the conveying process. Attached Figure Description

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] As shown in Figures 1-5, a cutting device for processing decorative parts for electric vehicle instrument panel covers includes a cutting table 1. A cutting device 2 is fixedly connected to the inner wall of the cutting table 1. An anti-warping device 3 is provided on the inner wall of the cutting table 1. The anti-warping device 3 includes two bidirectional threaded rods 31. The bottoms of the two bidirectional threaded rods 31 are rotatably connected to the inner wall of the cutting table 1. A torsion block 32 is fixedly connected to the top of the bidirectional threaded rods 31. Two movable plates 33 are threadedly connected to opposite circumferential surfaces of the bidirectional threaded rods 31. The sides of the two movable plates 33 are each provided with... The device includes a drive assembly. A limit rod 37 is fixedly connected to the inner wall of the cutting table 1. The drive assembly includes a motor 34. The side of the motor 34 is fixedly connected to the side of the moving plate 33. A rotating shaft 35 is fixedly connected to the output shaft of the motor 34. A rotating rod 38 rotates on the side of the moving plate 33. A track 36 is connected between the rotating rod 38 and the rotating shaft 35. The track 36 is the drive end of the drive assembly. The limit rod 37 is in contact with the moving plate 33. The inner diameter of the groove of the moving plate 33 is equal to the outer diameter of the limit rod 37, which restricts the moving plate 33 from moving up and down.

[0025] According to the above structure, the workpiece is placed between the two tracks 36. The operator twists the torsion block 32, and the rotation of the torsion block 32 drives the rotation of the bidirectional threaded rod 31. The rotation of the bidirectional threaded rod 31 drives the moving plate 33 to move towards each other under the restriction of the limiting rod 37, thereby clamping the workpiece. This avoids the problem of warping and non-standard cuts caused by the lack of vertical pressing and fixation during the conveying process of existing cutting devices when cutting the workpiece with a pressure knife. At the same time, the movement of the moving plate 33 drives the movement of the motor 34. The motor 34 is started, and the output shaft of the motor 34 rotates, which drives the rotating shaft 35 to rotate. The rotation of the rotating shaft 35 drives the tracks 36 to rotate, and the rotation of the tracks 36 avoids insufficient clamping force caused by prolonged use of the clamping surface.

[0026] As shown in Figures 1-5, a cleaning device 4 is provided on the side of the moving plate 33. The cleaning device 4 includes a connecting block 41, which is fixedly connected to the side of the moving plate 33. A connecting shaft 42 is fixedly connected to the end of the rotating rod 38 away from the track 36. A rotating shaft 43 is rotatably connected to the side of the connecting block 41. A conveyor belt 44 is connected between the connecting shaft 42 and the rotating shaft 43. A cleaning roller 45 is fixedly connected to the circumferential surface of the rotating shaft 43. The cleaning roller 45 is in contact with the track 36 and can clean the surface of the track 36. There is a gap between the track 36 and the moving plate 33 to avoid motion interference. The cleaning roller 45 is made of a high wear-resistant and low heat-conducting material. The connecting block 41 and the moving plate 33 are flush.

[0027] According to the above structure, the movement of the moving plate 33 drives the movement of the connecting block 41, and the rotation of the track 36 drives the rotation of the rotating rod 38. The rotation of the rotating rod 38 drives the rotation of the connecting shaft 42. The rotation of the connecting shaft 42 drives the rotation of the conveyor belt 44. The rotation of the conveyor belt 44 drives the rotation of the rotating shaft 43. The rotation of the rotating shaft 43 drives the rotation of the cleaning roller 45. The rotation of the cleaning roller 45 ensures that the device will not be crushed by the cut debris during the conveying process.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
