Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an automobile parts cutting device. Background Art

[0002] Cutting automotive parts is a crucial step in the automotive manufacturing process, involving a wide range of materials, processes, and equipment. The materials involved in cutting automotive parts vary, including metals (such as steel, aluminum, and copper), non-metals (such as plastics, rubber, and glass), and composite materials (such as carbon fiber reinforced plastics and glass fiber reinforced plastics). Different materials require different cutting methods and process parameters. Parts are cut using mechanical equipment such as cutting tools and cutting machines. This method is generally suitable for coarse cutting needs and is relatively cost-effective.

[0003] During the cutting process, due to reasons such as material unevenness, excessive gaps between the punch and die of the cutting equipment, or long-term wear, the cutting surface may be inconsistent, resulting in burrs. These burrs not only affect the appearance of automotive parts, but may also have adverse effects on subsequent assembly and use.

[0004] In the existing technical solutions, cutting and deburring of automotive parts are two relatively independent process steps. For parts produced in large quantities and with high surface quality requirements, mechanical deburring methods are mostly adopted. Mechanical grinding equipment such as sanding machines, grinders or cutting machines are used with appropriate sanding belts, grinding tools or cutters to grind away burrs. However, the burrs existing on the automotive parts after cutting are not simply deburred. As a result, when the parts are transferred to the deburring process step, the burrs may cause scratches to the transfer operators or transfer equipment. Summary of the Invention

[0005] The purpose of the present utility model is to provide an automobile parts cutting device, which can grind the cut parts of the fitted automobile parts by moving the grinding block, thereby realizing the grinding pretreatment operation of the parts after cutting. The pre-grinding treatment can remove sharp edges and corners, and protect the service life of subsequent processing equipment and tools. The burrs generated after cutting may pose a safety hazard to the operator, such as scratches, punctures, etc. The pre-grinding treatment can reduce this risk and improve the safety of the working environment, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an automobile parts cutting device, comprising a cutting platform, a cutting frame slidably mounted on the upper end of the cutting platform, a carrying rod slidably mounted on the inner side of the cutting frame, a cutting motor fixedly mounted on the lower end surface of the carrying rod, an assembly set fixedly mounted on the right side of the cutting motor, a drive shaft fixedly mounted on the output end of the cutting motor, and a cutting disc fixedly mounted on the output top end of the drive shaft;

[0007] A burr pretreatment component is provided in the middle position of the drive shaft, and a pressing component is provided at the bottom end of the assembly sleeve. The pressing component includes a pressing seat fixedly installed at the bottom end of the assembly sleeve, the interior of the pressing seat is a hollow structure, and a grinding groove is provided on the bottom end surface of the pressing seat. The burr pretreatment component includes a grinding block movably installed inside the grinding groove.

[0008] Preferably, the burr pretreatment assembly further comprises a first bevel gear fixedly mounted in the middle position of the drive shaft, a transmission shaft is rotatably mounted inside the assembly set, and a second bevel gear meshing with the first bevel gear is fixedly connected to the top end of the transmission shaft.

[0009] Preferably, a transmission disc is fixedly mounted on the bottom end of the transmission shaft, and a deflected connector is fixedly mounted on one side of the bottom end surface of the transmission disc.

[0010] Preferably, the outer sliding sleeve of the deflected connector is provided with an assembly plate, an engaging groove is opened inside the assembly plate, and an assembly push plate is fixedly installed on the side wall of the assembly plate close to the grinding block, and the assembly push plate has an L-shaped structure.

[0011] Preferably, an assembly fitting groove is provided at the bottom end of the assembly push plate corresponding to the grinding block, a plurality of springs are fixed inside the assembly fitting groove, and the grinding block is elastically fitted in the assembly fitting groove through the springs.

[0012] Preferably, a smoke extraction assembly is provided on the upper end surface of the bearing rod, and the smoke extraction assembly includes an air pump fixedly mounted on the upper end surface of the bearing rod, and a connecting pipe is connected between the air pump and the pressing seat.

[0013] Preferably, a plurality of wheel grooves are formed on the bottom end surface of the pressing seat, and pressing wheels are rotatably installed inside the wheel grooves.

[0014] Preferably, a cutting groove corresponding to the cutting disc is formed on the bottom end surface of the pressing seat, and a protective cover fixed to the bottom end surface of the bearing rod is sleeved on the upper outer side of the cutting disc.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The present invention can polish the cut parts of the fitted automobile parts by moving the polishing block, thereby realizing the polishing pretreatment operation after the parts are cut. The pre-polishing treatment can quickly remove large or obvious burrs generated during the cutting process, laying a good foundation for subsequent more refined polishing or deburring processes, thereby reducing the overall processing time; the pre-polishing treatment can remove sharp edges and corners, protecting the service life of subsequent processing equipment and tools, and avoiding the burrs generated after cutting. The sharp edges and corners may cause additional wear or damage to the processing equipment and tools if subsequent processing is directly carried out. At the same time, the burrs generated after cutting may pose a safety hazard to the operator, such as scratches and punctures. The pre-polishing treatment can reduce this risk and improve the safety of the working environment;

[0017] 2. The pressing assembly provided in the present invention can ensure that the automobile parts are pressed synchronously when the automobile parts are cut and moved. The pressing can ensure that the automobile parts will not be displaced or deformed due to external forces during the cutting process, thereby maintaining a high processing accuracy. At the same time, by ensuring the processing accuracy and stability, the pressing and fixing can reduce the scrap rate caused by processing errors or workpiece deformation, thereby reducing production costs; the set fume extraction assembly can prevent the odor generated by grinding and cutting from being directly discharged into the air. Through absorption treatment, the concentration of these harmful gases can be effectively reduced, reducing the risk of workers getting sick. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The utility model provides a technical solution:

The outer sliding sleeve of the deflected connector 705 is provided with an assembly plate 706, and an engaging groove 707 is provided inside the assembly plate 706. An assembly push plate 708 is fixedly installed on the side wall of the assembly plate 706 near the grinding block 709. The structure of the assembly push plate 708 is an L-shaped structure, and an assembly engaging groove 711 is provided at the bottom end of the assembly push plate 708 corresponding to the grinding block 709. A plurality of springs 710 are fixed inside the assembly engaging groove 711, and the grinding block 709 is elastically engaged in the assembly engaging groove 711 through the spring 710.

[0029] By adopting the above technical solution, when in use, the automobile parts to be cut are placed on the cutting platform 1, and the cutting processing frame 2 is composed of a horizontal drive component and a vertical drive component. The horizontal drive component includes a horizontal slide frame, a first speed-regulating motor, a first ball screw and a first guide rod. The vertical drive component is composed of a vertical slide frame, a second speed-regulating motor, a second ball screw and a second guide rod. When it is necessary to cut the automobile parts, the second speed-regulating motor is started, and the second speed-regulating motor drives the second ball screw to move the bearing rod 3 up and down on the vertical slide frame. The bearing rod 3 can push the pressing seat 111 downward through the cutting motor 4 and the assembly set 9. When it moves to the appropriate position, the cutting motor 4 is started. The cutting motor 4 can drive the driving shaft 6 to rotate, and the driving shaft 6 can drive the cutting disc 8 to rotate. In this way, the cutting disc 8 can be used to cut and process the automotive parts. When the driving shaft 6 rotates, the driving shaft 6 can drive the first bevel gear 701 to rotate. The rotation of the first bevel gear 701 can drive the meshing second bevel gear 702 to rotate. The second bevel gear 702 drives the transmission shaft 703 through the fixed connection. As the disk 704 rotates, the deflected connector 705 at the bottom of the transmission disk 704 can move left and right in the fitting groove 707 of the assembly plate 706. During the left and right movement, the assembly plate 706 can be pushed and pulled to perform telescopic movement. The assembly plate 706 is slidably installed in the hollow press-fit seat 111. In this way, the telescopic movement of the assembly plate 706 drives the grinding block 709 to move. The movement of the grinding block 709 can grind the cut portion of the fitted automobile parts, thereby realizing the pre-grinding operation after the parts are cut. The pre-grinding process can quickly remove the debris produced during the cutting process. Pre-grinding can remove sharp edges and corners, protect the service life of subsequent processing equipment and tools, and avoid burrs generated after cutting. Burrs may contain sharp edges and corners. If subsequent processing is carried out directly, it may cause additional wear or damage to processing equipment and tools. At the same time, burrs generated after cutting may pose a safety hazard to operators, such as scratches and punctures. Pre-grinding can reduce this risk and improve the safety of the working environment.

[0030] Specifically, such as Figures 1 to 3 As shown, a smoke extraction assembly 10 is provided on the upper end surface of the supporting rod 3, and the smoke extraction assembly 10 includes an air pump 101 fixedly mounted on the upper end surface of the supporting rod 3, and a connecting pipe 102 is connected between the air pump 101 and the pressing seat 111, and a plurality of wheel grooves 115 are provided on the bottom end surface of the pressing seat 111, and a pressing wheel 112 is rotatably installed inside the wheel groove 115, and a cutting groove 114 corresponding to the cutting disk 8 is provided on the bottom end surface of the pressing seat 111, and a protective cover 5 fixed to the bottom end surface of the supporting rod 3 is provided on the upper outer side of the cutting disk 8. The protective cover 5 can protect the cutting disk 8 to prevent debris generated when the cutting disk 8 is cutting from splashing.

[0031] By adopting the above technical solution, when in use, the pressing seat 111 moves downward to enable the pressing wheel 112 at the bottom of the pressing seat 111 to press the auto parts that need to be cut, so that the auto parts can be pressed synchronously when the cutting movement is carried out. The pressing can ensure that the auto parts will not be displaced or deformed due to external forces during the cutting process, thereby maintaining a high processing accuracy. At the same time, by ensuring the processing accuracy and stability, the pressing and fixing can reduce the scrap rate caused by processing errors or workpiece deformation, thereby reducing production costs. During cutting and grinding, the air pump 101 is started. The air pump 101 can absorb the air inside the hollow structure of the pressing seat 111 through the connecting pipe 102. The air pump 101 connects the absorbed air to the air purification equipment, which can avoid the odor generated by grinding and cutting being directly discharged into the air. Through absorption treatment, the concentration of these harmful gases can be effectively reduced, reducing the risk of workers getting sick.

[0032] Working principle: When in use, the automobile parts to be cut are placed on the cutting platform 1, and the carrying rod 3 can be moved on the cutting processing frame 2. The carrying rod 3 can push the pressing seat 111 to move downward through the cutting motor 4 and the assembly set 9. The downward movement of the pressing seat 111 can make the pressing wheel 112 at the bottom of the pressing seat 111 press the automobile parts to be cut, so that the automobile parts can be pressed synchronously when the automobile parts are cut and moved. Start the cutting motor 4. The cutting motor 4 can drive the driving shaft 6 to rotate. The rotation of the driving shaft 6 can drive the cutting disk 8 to rotate. In this way, the automobile parts can be cut and processed by the cutting disk 8. When the driving shaft 6 rotates, the driving shaft 6 can drive the first bevel gear 701 to rotate. The rotation of the first bevel gear 701 can drive the meshing second bevel gear 702 to rotate. The second bevel gear The wheel 702 drives the transmission disk 704 to rotate through the fixedly connected transmission shaft 703. The deflected connecting head 705 at the bottom end of the transmission disk 704 can move left and right in the fitting groove 707 of the assembly plate 706. During the left and right movement, the assembly plate 706 can be pushed and pulled to perform telescopic movement. The assembly plate 706 is slidably installed in the hollow pressing seat 111, so that the telescopic movement of the assembly plate 706 can drive the grinding block 709 to move. The movement of the grinding block 709 can grind the cut parts of the fitted automobile parts. During the cutting and grinding work, the air pump 101 is started. The air pump 101 can absorb the air inside the hollow structure of the pressing seat 111 through the connecting pipe 102. The air pump 101 connects the absorbed air with the air purification equipment, thereby preventing the odor generated by grinding and cutting from being directly discharged into the air.
