Description

Technical Field

[0001] The present invention relates to the technical field of automotive part cutting, and particularly to a cutting device for automotive part production. Background Art

[0002] In the field of automotive part manufacturing, the cutting process of tubular workpieces is a common operation. Traditional cutting devices mostly rely on manual or semi-automatic methods to complete loading and unloading, which have problems such as low efficiency, high labor intensity, and insufficient sorting accuracy. Especially for continuous cutting scenarios, the feeding mechanisms of existing equipment are difficult to achieve equidistant conveying of pipe fittings, and the qualified parts and residual tailings are often mixed after cutting, requiring additional sorting steps. In addition, if the pipe fittings are bent and deformed before processing, it is easy to cause cutting errors, and the existing technology lacks real-time straightness monitoring means during the cutting process, affecting the qualified rate of finished products.

[0003] The patent with the patent number CN202420405370.2 discloses a continuous pipe cutting device including a base, the bottom of the base is fixedly connected with table legs, the top of the base is fixedly connected with a telescopic rod, the circumferential surface of the telescopic rod is fixedly connected with a connecting rod, one end of the connecting rod is fixedly connected with a protective shell, the inner wall of the protective shell is rotatably connected with a cutting blade, and a fixing device is arranged on the top of the base, and the bottom of the fixing plate is fixedly connected to the top of the base;

[0004] When the above device is used, it still needs to rely on manual labor to complete loading and unloading, and the qualified parts and residual tailings are often mixed after cutting, requiring manual additional sorting steps, resulting in low efficiency and high labor intensity. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a cutting device for automotive part production to solve the problems that the existing automotive part cutting device relies on manual labor to complete loading and unloading, and the qualified parts and residual tailings are often mixed after cutting.

[0006] Based on the above purpose, the present invention provides a cutting device for automotive part production, including a substrate, one end of the top of which is provided with a cutting part, and a guide plate is also provided. The substrate is provided with a through hole, and a feeding component is arranged in the through hole. One side of the feeding component is provided with a baffle fixed to the substrate, and the other side is provided with a storage table for stacking pipe fittings;

[0007] The feeding component includes an annular plate and a limiting slideway fixed to its outer periphery. At least three sets of mounting blocks are slidably connected to the limiting slideway, and adjacent mounting blocks are connected by a connecting rope. Along the conveying direction of the annular plate, the first mounting block at the head end is provided with a pushing plate that overlaps the annular plate. A driving component for driving the pushing plate to move horizontally along the annular plate to push the workpiece to the cutting part is provided on the baffle. The last mounting block at the end is provided with a tail plate that overlaps the annular plate, and the middle mounting block is provided with a blocking component. A sliding plate is slidably provided at the bottom of the substrate located below the cutting part, and it is connected to the tail plate by a bolt rope. An energy storage component is also provided at the bottom of the substrate and is elastically connected to the sliding plate. The movement of the sliding plate causes the energy storage component to store elastic energy.

[0008] When the pushing plate moves out of the storage table, the pipe fitting rolls down to the annular plate by its own weight. The pushing plate pushes the pipe fitting to the cutting part to complete equidistant cutting, and the cut piece is discharged through the guide plate. During this period, the blocking component abuts against the subsequent pipe fittings on the storage table to prevent feeding. After the pushing plate reaches the cutting end, the tail plate drives the sliding plate to move out, and the residual pipe section at the cutting part automatically falls through the through hole.

[0009] Further, the blocking component includes an elastic member provided on the mounting block. A shaft rod is fixed to the free end of the elastic member, and a roller shaft is rotatably sleeved on the shaft rod. When the driving component drives the pushing plate, the roller shaft maintains contact with the workpiece through the elastic member.

[0010] Further, the elastic member includes a square rod slidably passing through the mounting block. One end of the square rod close to the baffle is provided with an end plate. A first spring sleeved on the square rod is connected between the end plate and the mounting block. The other end of the square rod is connected to the shaft rod.

[0011] Further, a distance measuring instrument for real-time measuring the distance between the shaft rod and the baffle is provided at the top of the shaft rod, and the distance measuring instrument is connected to an external control system.

[0012] Further, the driving component includes a housing. The housing is fixedly connected to the side of the baffle away from the annular plate. A threaded rod is rotatably connected inside the housing. A moving block is screwed on the threaded rod. The moving block fits with the inner cavity of the housing, and a driving motor for driving the threaded rod to rotate is provided at one end of the housing. Among them, a limiting hole is opened on the fitting surface between the baffle and the housing. A sliding rod slides in the limiting hole. One end of the sliding rod is connected to the moving block, and the other end passes through the mounting block and is connected to the pushing plate.

[0013] Further, the energy storage component includes a fixing plate. The fixing plate is fixed to one end of the bottom of the substrate away from the cutting part. A second spring is connected between the fixing plate and the sliding plate.

[0014] Further, the cutting part includes a cutting device and a fixing component provided at one end of the substrate. The fixing component includes a fixing base. An abutting block slides in the fixing base. A cutting through groove is opened on the abutting block. A hydraulic rod for driving the abutting block to move is also provided in the fixing base.

[0015] Further, the cutting device includes an inclined base, on the top surface of which a sliding seat is slidably arranged, and at the top end of which an electric push rod is provided for pushing the sliding seat to move along the top surface of the inclined base. A servo motor is fixed on the sliding seat, and a cutting disc is arranged at the output end of the servo motor. The cutting disc corresponds to the cutting through groove, and the servo motor can drive the cutting disc to rotate to cut the workpiece.

[0016] Further, a block for blocking the workpiece from falling is slidably arranged on the front side of the wing plate on the side of the storage table away from the cutting part. One end of the block away from the cutting part is connected with a back plate, and a third spring is connected between the back plate and the storage table; driving the back plate to move moves the free end of the block into the wing plate, and the pipe fitting can be fed from the storage table to the annular plate.

[0017] Further, a sliding hole is formed in the base plate, a connecting rod is slidably arranged in the sliding hole, the top of the connecting rod is connected with the bottom of the back plate, and the bottom of the connecting rod passes through the through hole and leaks downward; one end of the sliding plate close to the connecting rod is connected with an L-shaped shifting rod. When the sliding plate moves, it drives the shifting rod to move, and drives the back plate to move through the connecting rod, thereby driving the block to move, and controlling the feeding of the workpiece.

[0018] The cutting device for automobile part production provided by the present invention realizes the full-process automation of automatic feeding, precise equidistant pushing, cutting and sorting of pipe fittings through the linkage design of the feeding component and the driving component, improving production efficiency; the division of labor and cooperation between the guiding plate and the through hole can accurately separate qualified parts and residual tail materials, avoiding manual sorting errors; the distance measuring instrument of the blocking component monitors the straightness of the pipe fitting in real time, and combines the dynamic adjustment function of the elastic roller shaft to ensure that the straightness of the workpiece before cutting meets the standard and improve the processing accuracy.

[0035] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following further elaborates on the present invention in conjunction with specific embodiments.

[0036] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should have the ordinary meanings understood by those of ordinary skill in the field to which the present invention pertains.

[0037] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 ,Figure 11 , Figure 12 , Figure 13 As shown in Figure 11 , Figure 12 , and Figure 13 , a cutting device for automobile part production includes a base plate 1. At one end of its top, a cutting part is provided, and a material guiding plate 4 is also provided. At the bottom of the material guiding plate 4, a first storage box 13 is provided. The base plate 1 is provided with a through hole 101. Inside the through hole 101, a material conveying component 5 is provided. On one side of the material conveying component 5, a baffle 7 fixed to the base plate 1 is provided, and on the other side, a storage table 8 for stacking pipe fittings is provided; The material conveying component 5 includes an annular plate 501 and a limiting slideway 502 fixed to its outer periphery. At least three mounting blocks 503 are slidably connected to the limiting slideway 502, and adjacent mounting blocks 503 are connected by a connecting rope 506; Along the conveying direction of the annular plate 501, at the first mounting block 503 at the head end, a push plate 504 that overlaps the annular plate 501 is provided. On the baffle 7, a driving component 12 for driving the push plate 504 to move horizontally along the annular plate 501 to push the workpiece to the cutting part is provided. At the last mounting block 503 at the tail end, a tail plate 505 that overlaps the annular plate 501 is provided, and a blocking component 6 is provided on the middle mounting block 503; At the bottom of the base plate 1 below the cutting part, a sliding plate 901 is slidably provided, which is connected to the tail plate 505 by a bolt rope 904. At the bottom of the base plate 1, an energy storage component 9 is also provided and elastically connected to the sliding plate 901. The movement of the sliding plate 901 elastically stores energy in the energy storage component 9 to keep the connecting rope 506 and the bolt rope 904 taut. The connecting rope 506 is a non-elastic rope to ensure the synchronous movement of the push plate 504 and the tail plate 505;

[0038] When the driving push plate 504 moves out of the storage table 8, the pipe fitting rolls onto the annular plate 501 by its own weight. The push plate 504 pushes the pipe fitting to the cutting part to complete equidistant cutting. The cut parts are fed into the first storage box 13 through the material guiding plate 4; During this period, the blocking component 6 abuts against the subsequent pipe fittings on the storage table 8 to prevent feeding; After the push plate 504 reaches the cutting end, the tail plate 505 drives the sliding plate 901 to move out, and the residual pipe section of the cutting part automatically falls into the second storage box 14 through the through hole 101.

[0039] In this embodiment, the pipe fittings in the storage table 8 roll onto the annular plate 501 of the material conveying assembly 5 under their own weight. The driving assembly 12 pushes the push plate 504 to move horizontally along the limiting slideway 502, and pushes the pipe fittings to the cutting part for equidistant cutting. During this process, the blocking assembly 6 of the middle mounting block 503 abuts against the subsequent pipe fittings in the storage table 8 to prevent them from rolling and interfering with the current process. The qualified workpieces after cutting slide out for blanking through the guide plate 4. When the push plate 504 moves to the extreme position at the cutting end, the tail plate 505 of the end mounting block 503 drives the bottom sliding plate 901 to slide through the tie rope 904, so that the energy storage assembly 9 stretches and stores energy. When the push plate 504 moves to the extreme position at the cutting end, the through hole 101 at the bottom of the cutting part is exposed at this time, and the residual pipe section automatically drops through the through hole 101 to complete the material separation. Subsequently, the driving assembly 12 drives the push plate 504 and the tail plate 505 to return to the initial position, and the next pipe fitting automatically rolls onto the annular plate 501 to enter a new round of cutting cycle.

[0040] Through the linkage design of the material conveying assembly 5 and the driving assembly 12, this device realizes the full-process automation of automatic feeding, equidistant pushing, cutting and sorting of pipe fittings. By using the linkage of the push plate 504, the tail plate 505 and the sliding plate 901 and the division of labor and cooperation between the guide plate 4 and the through hole 101, the qualified parts and the residual tail materials can be separated, avoiding the sorting error of manual labor.

[0041] Preferably, the blocking assembly 6 includes an elastic member provided on the mounting block 503. A shaft rod 604 is fixed to the free end of the elastic member, and a roller shaft 605 is rotatably sleeved on the shaft rod 604. When the driving assembly 12 drives the push plate 504, the roller shaft 605 keeps in contact with the workpiece through the elastic member.

[0042] The elastic member includes a square rod 601 slidably passing through the mounting block 503. One end of the square rod 601 close to the baffle 7 is provided with an end plate 602. A first spring 603 sleeved on the square rod 601 is connected between the end plate 602 and the mounting block 503. The other end of the square rod 601 is connected to the shaft rod 604.

[0043] A rangefinder 606 for real-time measuring the distance between the shaft rod 604 and the baffle 7 is provided at the top of the shaft rod 604, and the rangefinder 606 is connected to an external control system.

[0044] In this embodiment, when the driving component 12 pushes the push plate 504 to move, the roller 605 of the blocking component 6 contacts the surface of the subsequent pipe on the storage platform 8 through the elastic member; specifically, the subsequent pipe presses down the roller 605 to drive the shaft 604 to move toward the baffle 7, and the square rod 601 slides accordingly and compresses the first spring 603 sleeved thereon; the elastic force of the first spring 603 makes the roller 605 always close to the surface of the pipe, preventing the subsequent pipe from rolling down and interfering with the current feeding, and avoiding damage to the workpiece caused by rigid contact; at the same time, the rangefinder 606 on the top of the shaft 604 detects the distance change between the shaft 604 and the baffle 7 in real time, and feeds back the data to the external control system. The rangefinder 606 monitors the displacement of the shaft 604 and feeds back the straightness data of the pipe in real time. If the pipe is bent or deformed, the distance measurement value will fluctuate abnormally, and the control system can issue an early warning or adjust the cutting parameters accordingly to ensure processing accuracy.

[0045] Preferably, the driving assembly 12 includes a shell 1201, which is fixedly connected to the side of the baffle 7 away from the annular plate 501, and a threaded rod 1202 is rotatably connected in the shell 1201, and a moving block 1203 is screwed on the threaded rod 1202, and the moving block 1203 is fitted with the inner cavity of the shell 1201, and a driving motor 1204 for driving the threaded rod 1202 to rotate is provided at one end of the shell 1201; wherein, a limiting hole 701 is provided on the fitting surface of the baffle 7 and the shell 1201, and a sliding rod slides in the limiting hole 701, one end of the sliding rod is connected to the moving block 1203, and the other end is connected to the push plate 504 after passing through the mounting block 503;

[0046] When the driving component 12 is started, the driving motor 1204 at one end of its shell 1201 drives the threaded rod 1202 to rotate, driving the moving block 1203 screwed on the threaded rod 1202 to move horizontally along the inner cavity of the shell 1201; the moving block 1203 slides in the limiting hole 701 of the baffle 7 through the sliding rod, pushing the push plate 504 to move along the limiting slide 502 of the annular plate 501 toward the cutting part, thereby pushing the pipe to the cutting position; after the cutting is completed, the driving motor 1204 is reversed, the threaded rod 1202 drives the moving block 1203 to move in the opposite direction, and the sliding rod pulls the push plate 504 to return to the initial position. At this time, the energy storage component 9 releases the elastic potential energy, and the linkage sliding plate 901 and the tail plate 505 are synchronously reset to complete a cutting cycle.

[0047] Preferably, the energy storage assembly 9 includes a fixed plate 902, and the fixed plate 902 is fixed to one end of the bottom of the substrate 1 away from the cutting portion, and a second spring 903 is connected between the fixed plate 902 and the sliding plate 901;

[0048] After the push plate 504 pushes the pipe fitting to the cutting part to complete the cutting, the tail plate 505 of the end mounting block 503 pulls the sliding plate 901 to slide away from the cutting part through the tie rope 904. At this time, the second spring 903 between the sliding plate 901 and the fixed plate 902 is stretched and stores energy. The residual pipe section after cutting automatically drops through the through hole 101 of the substrate 1; subsequently, when the driving assembly 12 drives the push plate 504 to reset, the second spring 903 releases its elastic potential energy, driving the tail plate 505 and the sliding plate 901 to return to the initial position.

[0049] Preferably, the cutting part includes a cutting device 2 and a fixing component 3 arranged at one end of the substrate 1; the fixing component 3 includes a fixing base 301, a contact block 302 slides in the fixing base 301, a cutting through groove 303 is arranged on the contact block 302, and a hydraulic rod 304 for driving the contact block 302 to move is further arranged in the fixing base 301;

[0050] The cutting device 2 includes an inclined base 201, a sliding seat 203 is slidably arranged on the top surface thereof, an electric push rod 202 for pushing the sliding seat 203 to move along the top surface of the inclined base 201 is arranged at the top end thereof, a servo motor 204 is fixed on the sliding seat 203, a cutting disc 205 is arranged at the output end of the servo motor 204, the cutting disc 205 corresponds to the cutting through groove 303, and the servo motor 204 can drive the cutting disc 205 to rotate to cut the workpiece;

[0051] In this embodiment, when the pipe fitting is first conveyed to the annular plate 501, in order to ensure the cutting accuracy of the first section, a positioning and calibration process is performed; specifically, first, the hydraulic rod 304 is started to drive the contact block 302 to move towards the inclined base 201 and abut, and at the same time the driving assembly 12 drives the push plate 504 to push the pipe fitting, so that the end of the pipe fitting is completely attached to the contact block 302, completing the precise calibration of the initial position of the pipe fitting. After the calibration is completed, the hydraulic rod 304 retracts to drive the contact block 302 to reset; the first movement of the push plate 504 after calibration will push the pipe fitting to the designated cutting station according to the sum of the preset cutting length and the distance between the contact block 302 and the cutting through groove 303, and subsequent movements will be in accordance with the cutting length standard; when the pipe fitting is pushed by the push plate 504 to the cutting part, the hydraulic rod 304 of the fixing component 3 drives the contact block 302 to slide in the fixing base 301 to clamp and fix the pipe fitting; subsequently, the electric push rod 202 of the cutting device 2 is started to push the sliding seat 203 to slide along the top surface of the inclined base 201 towards the pipe fitting, and at the same time the servo motor 204 drives the cutting disc 205 to rotate at a high speed to complete the cutting of the workpiece. The cut pipe fitting automatically drops through the guide plate 4; after the cutting is completed, the electric push rod 202 retracts to drive the sliding seat 203 to reset, and the hydraulic rod 304 simultaneously releases the contact block 302 to release the fixation of the workpiece, waiting for the push plate 504 to push the pipe fitting to move again.

[0052] Preferably, a stopper 801 for blocking the workpiece from falling is slidably arranged on the front side of the wing plate on the side of the storage table 8 away from the cutting part. One end of the stopper 801 away from the cutting part is connected to a back plate 802, and a third spring 803 is connected between the back plate 802 and the storage table 8; driving the back plate 802 to move moves the free end of the stopper 801 into the wing plate, and the pipe fitting can fall from the storage table 8 to the annular plate 501;

[0053] A sliding hole 102 is formed in the substrate 1, and a connecting rod 10 is slid in the sliding hole 102. The top of the connecting rod 10 is connected to the bottom of the back plate 802, and the bottom of the connecting rod 10 passes through the through hole 101 and leaks downward; one end of the sliding plate 901 close to the connecting rod 10 is connected to an L-shaped lever 11. When the sliding plate 901 moves, it drives the lever 11 to move to drive the back plate 802 to move through the connecting rod 10, thereby driving the stopper 801 to move to control the workpiece from falling;

[0054] In this embodiment, when the driving assembly 12 drives the push plate 504 to reset, the second spring 903 releases elastic potential energy, pushes the sliding plate 901 to slide reversely and reset, and drives the tail plate 505 and the push plate 504 to return to the initial position; at this time, the sliding plate 901 controls the stopper 801 of the storage table 8 to release the block through the lever 11 and the connecting rod 10, so that the next pipe fitting rolls onto the annular plate 501 and enters a new round of cutting cycle; when the driving assembly 12 drives the sliding plate 901 to move away from the cutting part, the third spring 803 releases elastic force to push the back plate 802 back to its original position, and the free end of the stopper 801 extends out of the wing plate again to block the subsequent pipe fittings from falling, ensuring that only a single pipe fitting enters the feeding assembly 5 each time.

[0055] Preferably, a clamping assembly 15 is further arranged on the top of the push plate 504 for clamping and fixing the pipe fitting on the annular plate 501; the clamping assembly 15 includes a support rod 1501 arranged on the top of the push plate 504, the other end of the support rod 1501 is fixed with an electric drive rod 1502, and the output end at the bottom of the electric drive rod 1502 is fixed with a clamping plate 1503. The electric drive rod 1502 pushes the clamping plate 1503 to move downward and closely adhere to the outer circumference of the pipe fitting, which can fix the pipe fitting on the annular plate 501, avoid the pipe fitting from shaking, and improve the stability of the subsequent conveying of the pipe fitting.
