Description

Technical Field

[0001] This invention belongs to the field of automotive parts processing technology and relates to an intelligent processing equipment for automotive parts. Background Technology

[0002] Automotive parts processing is a crucial part of the automotive manufacturing industry, with a large number of automotive parts requiring precision shaping through machining. With the rapid development of the automotive industry, the demands on automotive parts machining equipment are constantly increasing, requiring not only higher production efficiency and machining accuracy but also greater emphasis on safety during the production process.

[0003] In the machining of automotive parts, the cutting blade rotates at a high speed, possessing significant rotational kinetic energy and inertia. In emergency situations, such as workpiece loosening, blade chipping, or equipment malfunction, the cutting blade must be able to stop rotating quickly to prevent serious personal injury and equipment damage.

[0004] Currently, conventional safety protection measures mainly involve cutting off the motor power supply to stop the machine. This method of power disconnection only removes the motor's active driving force but cannot eliminate the enormous rotational inertial kinetic energy carried by the cutting blade itself. After the power is cut off, the cutting blade often continues to rotate for a certain period of time due to inertia and cannot stop completely in a short time, increasing the possibility of danger.

[0005] To address the above problems, this invention proposes an intelligent processing equipment for automotive parts. Summary of the Invention

[0006] To address the problems existing in the background technology, the present invention proposes an intelligent processing equipment for automotive parts.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an intelligent processing equipment for automotive parts, comprising:

[0008] A slide table, on which a support frame is mounted;

[0009] A rotating shaft is rotatably mounted on the support frame, with a cutting blade for processing automotive parts mounted at one end and a first bevel gear mounted at the other end.

[0010] A motor is mounted on the slide table and moves up and down. A second bevel gear is mounted on the output shaft of the motor.

[0011] A metal strip passes over the outside of the rotating shaft, and both ends of the metal strip are fixedly connected to the motor;

[0012] A driving component is used to drive the motor to move upward and to keep the second bevel gear meshing with the first bevel gear;

[0013] When an emergency stop is required, the motor moves downward, the second bevel gear disengages from the first bevel gear, and at the same time the motor pulls both ends of the metal strip downward, so that the metal strip hugs the outer circumference of the rotating shaft, causing the rotating shaft to stop rotating.

[0014] Furthermore, two limiting slides are fixedly installed on the slide platform, and a mounting plate is slidably connected between the two limiting slides, with the motor fixedly mounted on the mounting plate.

[0015] Furthermore, the driving component includes a second cylinder, which is mounted on the slide, and the telescopic end of the second cylinder engages with the bottom of the mounting plate.

[0016] Furthermore, a portion of the metal strip forms a ring structure and is fitted onto the outside of the rotating shaft; when the second bevel gear and the first bevel gear are meshed, the metal strip and the rotating shaft do not contact each other; when the motor moves downward, the diameter of the ring structure of the metal strip decreases and it hugs the outer circumference of the rotating shaft.

[0017] Furthermore, a torque sensor is provided on the rotating shaft, and both the torque sensor and the drive component are electrically connected to the controller; the controller controls the movement of the drive component based on the real-time torque signal fed back by the torque sensor.

[0018] Furthermore, the controller pre-stores an idle reference torque value N1 and a cutting reference torque value N2. When the difference between the real-time torque value N3 monitored by the torque sensor and the corresponding idle reference torque value N1 or cutting reference torque value N2 exceeds a set threshold, the controller controls the drive component to remove the support force on the motor, triggering an emergency stop.

[0019] Furthermore, the support frame is fixedly connected to a housing, the cutting blade is rotatably disposed within the housing, and the housing has an outlet.

[0020] Furthermore, the slide table is slidably mounted on the slide rail, and the slide rail is mounted on the fixed frame;

[0021] A collection box is installed on the fixed frame, and the collection box is set corresponding to the discharge port to collect debris falling from the discharge port.

[0022] Furthermore, a first cylinder is installed on the fixed frame, and the telescopic end of the first cylinder is fixedly connected to the slide table for driving the slide table to slide along the slide rail.

[0023] Furthermore, a friction layer is provided on the inner surface of the metal strip.

[0024] Compared with existing technologies, this invention has the following advantages: In an emergency, the second cylinder retracts rapidly, and after the mounting plate loses its support, the motor falls rapidly under its own weight. The second bevel gear immediately disengages from the first bevel gear, cutting off the power input. Simultaneously, the motor pulls both ends of the metal strip downwards, causing the annular structure of the metal strip to narrow and tightly grip the shaft, forcing the cutting blade to stop rotating within a short time. This improves the emergency stop speed and effectively reduces safety risks.

[0025] The initial annular inner diameter of the metal strip does not need to be precisely matched with the outer diameter of the shaft. During braking, it can adaptively grip shafts of different diameters through elastic contraction, resulting in high versatility. At the same time, the second cylinder and the mounting plate are in movable contact without fixed connection. During emergency stop, the motor falls freely, and the metal strip will not be broken. This eliminates the need to repeatedly adjust the stroke of the second cylinder according to different shaft diameters, simplifying the preliminary preparation work. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1-8 As shown, the technical solution adopted by the present invention is as follows: an intelligent processing equipment for automotive parts includes a cutting table 1, a fixed frame 2, a slide table 4, a rotating shaft 7, a motor 14, a metal strip 16, and a driving component.

[0037] like Figure 1 , Figure 2 As shown, the cutting table 1 is fixedly connected to the fixed frame 2. The cutting table 1 is used to support the automotive parts to be processed. The top of the cutting table 1 is provided with a structure for fixing the automotive parts. The structure for fixing the automotive parts is existing technology and can be set as needed, so it will not be described in detail here.

[0038] like Figure 3 As shown, a slide rail 3 is fixedly installed on the mounting bracket 2, and the slide rail 3 extends horizontally. The slide table 4 is slidably connected to the slide rail 3 and can slide back and forth along the extension direction of the slide rail 3. Specifically, there are two slide rails 3 arranged in parallel, and the slide table 4 spans between the two slide rails 3 to ensure the smoothness of the sliding process.

[0039] A first cylinder 5 is fixedly installed on the fixed frame 2, and the telescopic end of the first cylinder 5 is fixedly connected to the slide table 4. The first cylinder 5 is used to drive the slide table 4 to slide along the slide rail 3.

[0040] A support frame 6 is fixedly mounted on the top of the slide table 4. The rotating shaft 7 is rotatably mounted on the support frame 6.

[0041] like Figure 4 , Figure 6 As shown, a cutting blade 8 is fixedly mounted on one end of the rotating shaft 7. The cutting blade 8 is a disc-shaped saw blade or milling cutter with cutting edges for cutting automotive parts. The diameter of the cutting blade 8 is determined according to the processing requirements. A through slot is provided on the cutting table 1, and the top of the cutting blade 8 extends through the through slot to the top of the cutting table 1 to facilitate cutting the automotive parts on the cutting table 1.

[0042] A first bevel gear 13 is fixedly installed at the other end of the rotating shaft 7, and the axis of the first bevel gear 13 coincides with the axis of the rotating shaft 7.

[0043] A limiting slide 18 is fixedly installed on the top of the slide table 4, and the limiting slide 18 extends vertically. In this embodiment, there are two limiting slides 18, which are parallel and opposite to each other. Each limiting slide 18 has a groove extending vertically. A limiting stop is provided at the top of the limiting slide 18.

[0044] A mounting plate 17 is slidably connected between the two limiting slides 18. Specifically, sliding blocks are provided on both sides of the mounting plate 17, and the sliding blocks are slidably disposed in the slide grooves of the limiting slides 18. The mounting plate 17 slides vertically along the slide grooves.

[0045] The motor 14 is fixedly mounted on the mounting plate 17 and moves up and down together with the mounting plate 17.

[0046] A second bevel gear 15 is fixedly connected to the output shaft of the motor 14, and the second bevel gear 15 rotates synchronously with the output shaft of the motor 14. The second bevel gear 15 meshes with the first bevel gear 13 to transmit the power of the motor 14 to the rotating shaft 7. When the mounting plate 17 is at the top limit position of the limiting slide 18, the second bevel gear 15 and the first bevel gear 13 are in a fully meshed state.

[0047] A driving component for moving the mounting plate 17 up and down is installed on the slide table 4. In this embodiment, the driving component includes a second cylinder 19. The second cylinder 19 is fixedly installed on the slide table 4 and is located below the mounting plate 17. The second cylinder 19 is arranged vertically, with its telescopic end extending upwards. The telescopic end of the second cylinder 19 is in movable contact with the bottom end face of the mounting plate 17, and there is no fixed connection between the two. In other words, the second cylinder 19 only pushes the bottom of the mounting plate 17 upwards through its telescopic end, without being fixedly connected to the mounting plate 17. When the second cylinder 19 extends, its telescopic end pushes the mounting plate 17 upwards along the limiting slide 18. When the second cylinder 19 retracts, its telescopic end retracts downwards, separating from the bottom of the mounting plate 17. After losing support, the mounting plate 17 falls freely under the gravity of the motor 14.

[0048] The second cylinder 19 is connected to an external air source via a pipeline. A solenoid valve is installed on the pipeline and is electrically connected to a controller. The controller controls the extension, retraction, and holding actions of the second cylinder 19.

[0049] The metal strip 16 is fixedly connected to the housing of the motor 14. Specifically, the metal strip 16 wraps around the outside of the rotating shaft 7, that is, the middle part of the metal strip 16 is arranged around the outer periphery of the rotating shaft 7. The two ends of the metal strip 16 are respectively fixedly connected to the two sides of the housing of the motor 14. The metal strip 16 is made of elastic metal material, preferably a spring steel strip in this embodiment. Its thickness and width are selected by calculation so that the internal stress is lower than the yield strength of the material when tightened, thus avoiding plastic deformation.

[0050] like Figure 7 , Figure 8 As shown, a portion of the metal strip 16 forms a ring structure, which is fitted onto the outer side of the rotating shaft 7. When the second bevel gear 15 and the first bevel gear 13 are meshing, the inner diameter of the ring structure is larger than the outer diameter of the rotating shaft 7, and a gap is left between the inner wall of the ring structure and the outer circular surface of the rotating shaft 7, so the two do not contact each other.

[0051] When the motor 14 moves downward, the two ends of the metal strip 16 move downward, which reduces the diameter of the ring structure of the metal strip 16 and makes it hug the rotating shaft 7, causing the rotating shaft 7 to stop rotating.

[0052] A friction layer is fixedly disposed on the inner surface of the metal strip 16. The friction layer is used to increase the friction between the metal strip 16 and the rotating shaft 7 when the metal strip 16 grips the shaft 7, thereby stopping the shaft 7 from rotating. In one embodiment, the friction layer is a vulcanized rubber layer, which is fixed to the inner surface of the metal strip 16 by bonding or vulcanization. In other embodiments, the friction layer may also be a polyurethane layer, an asbestos-based friction material layer, or a ceramic fiber friction material layer.

[0053] like Figure 5 As shown, a torque sensor 9 is installed on the rotating shaft 7 to detect the torque borne by the rotating shaft 7 in real time. The torque sensor 9 is electrically connected to the controller, and the torque sensor 9 feeds back the detected real-time torque value N3 to the controller.

[0054] like Figure 4 As shown, a housing 10 is fixedly connected to the support frame 6 and is disposed outside the cutting blade 8. The housing 10 has a semi-enclosed structure, covering the cutting blade 8, and is used to collect the chips generated during the cutting process. The cutting blade 8 is rotatably disposed inside the housing 10, that is, the cutting blade 8 rotates within the internal space of the housing 10. A discharge port 11 is provided at the bottom of the housing 10, which is used to discharge the chips that fall into the housing 10.

[0055] A collection box 12 is fixedly installed on the fixed frame 2, located below the discharge outlet 11 and corresponding to the discharge outlet 11, to receive the debris falling from the discharge outlet 11, so as to realize the centralized collection and subsequent unified treatment of the debris.

[0056] The controller can be an industrial programmable logic controller (PLC), a microcontroller, or an industrial computer. The controller includes a processor, memory, input / output interfaces, and a communication interface. The memory stores the control program and preset reference torque values, including an idle reference torque value N1 and a cutting reference torque value N2. The processor executes the control program, controlling the actions of each actuator based on the real-time torque signal fed back from the torque sensor 9.

[0057] When the cutting blade 8 is idling, if the difference between the real-time torque value N3 monitored by the torque sensor 9 and the idling reference torque value N1 exceeds a set threshold, the controller controls the second cylinder 19 to shorten and remove the support force on the motor 14, triggering an emergency stop. When the cutting blade 8 is in the cutting state, if the difference between the real-time torque value N3 monitored by the torque sensor 9 and the cutting reference torque value N2 exceeds a set threshold, the controller controls the second cylinder 19 to shorten and remove the support force on the motor 14, triggering an emergency stop.

[0058] This equipment also includes an operation panel, which is electrically connected to the controller. The operation panel is equipped with a start button, a stop button, an emergency stop button, and status indicator lights to facilitate human-machine interaction for operators.

[0059] Working principle: In the initial state, the second cylinder 19 is in the extended state, and its telescopic end pushes the bottom of the mounting plate 17 upward, causing the mounting plate 17 to slide along the limiting slide 18 to the top limit position. When the mounting plate 17 is at the top limit position, it is limited by the limiting stop at the top of the limiting slide 18 and cannot move further upward. At this time, the motor 14, which is fixedly mounted on the mounting plate 17, is in a high position, and the second bevel gear 15 on the output shaft of the motor 14 is fully engaged with the first bevel gear 13 at the end of the rotating shaft 7.

[0060] In this initial state, such as Figure 7 As shown, the annular structure of the metal strip 16 is sleeved on the outside of the rotating shaft 7, but there is a gap between the inner wall of the metal strip 16 and the outer circular surface of the rotating shaft 7, so the two do not contact each other.

[0061] The motor 14 is started, and its output shaft drives the second bevel gear 15 to rotate. The second bevel gear 15 drives the first bevel gear 13 to rotate, which in turn drives the rotating shaft 7 to rotate. The rotating shaft 7 then drives the cutting blade 8 to rotate synchronously. Simultaneously, the extension and retraction of the first cylinder 5 drives the slide table 4 to move laterally along the slide rail 3. The slide table 4 then moves the support frame 6, its rotating shaft 7, and the cutting blade 8 together. Thus, through the high-speed rotation and horizontal feed motion of the cutting blade 8, normal cutting operations can be performed on the automotive parts fixed on the cutting table 1.

[0062] Torque sensor 9 detects the torque of shaft 7 in real time and feeds back the real-time torque value N3 to the controller. The controller compares the real-time torque value N3 with the pre-stored reference torque value according to the current working state (idling or cutting) to determine whether the cutting state is normal.

[0063] Specifically, the control logic in this embodiment is as follows:

[0064] Before using the equipment, the operator or commissioning personnel input two reference torque values ​​into the controller through the operation panel.

[0065] Idle reference torque value N1: The torque value of the shaft 7 sensed by the torque sensor 9 when the cutting blade 8 is in an idle state (i.e., the cutting blade 8 is rotating but not in contact with the workpiece). This value reflects the basic torque of the equipment when it is running under no-load.

[0066] Cutting reference torque value N2: The torque value of the rotating shaft 7 sensed by the torque sensor 9 when the cutting blade 8 is normally cutting automotive parts. This value reflects the torque during normal cutting operations.

[0067] The aforementioned idle reference torque value N1 and cutting reference torque value N2 are stored in the controller's memory as a reference for subsequent judgments.

[0068] Normal operating status assessment:

[0069] When the cutting blade 8 is in an idling state, the torque sensor 9 feeds back the real-time torque value N3 to the controller. The controller compares the real-time torque value N3 with the idling reference torque value N1. When the absolute value of the difference between the real-time torque value N3 and the idling reference torque value N1 is less than a set threshold, the controller determines that the cutting blade 8 is in a normal idling state and does not trigger an emergency stop.

[0070] When the cutting blade 8 is in the cutting state, the controller compares the real-time torque value N3 with the cutting reference torque value N2. When the absolute value of the difference between the real-time torque value N3 and the cutting reference torque value N2 is less than a set threshold, the controller determines that the cutting blade 8 is in a normal cutting state and does not trigger an emergency stop.

[0071] Abnormal state judgment and emergency stop triggering:

[0072] When the cutting blade 8 is in an idling state, if the real-time torque value N3 differs significantly from the idling reference torque value N1 (i.e., the absolute value of the difference between the two is greater than or equal to the preset threshold), the controller determines that an abnormality has occurred (such as the cutting blade 8 abnormally contacting the workpiece, equipment jamming, etc.), controls the second cylinder 19 to shorten, triggering an emergency stop.

[0073] When the cutting blade 8 is in the cutting state, if the real-time torque value N3 differs significantly from the cutting reference torque value N2 (i.e., the absolute value of the difference between the two is greater than or equal to the preset threshold), the controller determines that an abnormality has occurred (such as the cutting blade 8 chipping, workpiece displacement, abnormal increase or decrease in cutting force, etc.), controls the second cylinder 19 to shorten, triggering an emergency stop.

[0074] In case of an emergency during the cutting process, this equipment can achieve a rapid emergency stop. The specific working process is as follows:

[0075] Torque sensor 9 detects the torque of shaft 7 in real time and feeds back the real-time torque value N3 to the controller. The controller compares the real-time torque value N3 with the preset reference torque value. When the difference between the two exceeds the set threshold, the controller determines that the current state is abnormal and immediately issues an emergency stop control signal.

[0076] The emergency stop control signal output by the controller is transmitted to the solenoid valve of the second cylinder 19, controlling the second cylinder 19 to shorten. The second cylinder 19 quickly switches from the extended state to the shortest state, and its extension end retracts downward.

[0077] Since the extension end of the second cylinder 19 and the bottom of the mounting plate 17 only have a movable contact fit and there is no fixed connection between them, when the second cylinder 19 is shortened, the bottom of the mounting plate 17 is no longer supported and lifted by the second cylinder 19. Under the action of the motor 14's own gravity, the mounting plate 17 slides rapidly downward along the limiting slide 18, and the mounting plate 17 drives the motor 14, the second bevel gear 15 and the metal strip 16 to move downward together.

[0078] It should be noted that the motor 14 that drives the cutting blade 8 to rotate is generally a high-power motor, which is relatively large in size and weight. Under the gravity of the motor 14, the mounting plate 17 moves rapidly downward along the limiting slide 18.

[0079] As the mounting plate 17 and motor 14 move downwards, the second bevel gear 15 moves downwards along with the output shaft of the motor 14, disengaging from the first bevel gear 13. At this point, the cutting blade 8 loses its rotational power and continues to rotate solely due to inertia.

[0080] At the same time, as the motor 14 moves downward, it pulls both ends of the metal strip 16 downward, causing the diameter of the annular structure formed by the metal strip 16 to gradually decrease. The friction layer on the inner side of the metal strip 16 gradually approaches and eventually fits tightly against the outer surface of the rotating shaft 7, thus achieving a tight grip on the rotating shaft 7.

[0081] After the metal strip 16 clamps tightly onto the outer surface of the rotating shaft 7, the friction between the friction layer on the inner side of the metal strip 16 and the outer surface of the rotating shaft 7 acts on the outer surface of the rotating shaft 7, generating a frictional torque opposite to the rotation direction of the rotating shaft 7, causing the rotational speed of the rotating shaft 7 to decrease rapidly. Under the clamping friction action of the metal strip 16, the rotating shaft 7 and the cutting blade 8 quickly stop rotating, achieving a rapid emergency stop. Compared to simply stopping the cutting blade 8 naturally by cutting off the power, this solution applies friction to the outer surface of the rotating shaft 7 through the metal strip 16, which can significantly shorten the stopping time of the cutting blade 8 and effectively reduce the safety risks caused by the inertial rotation of the cutting blade 8.

[0082] During the above emergency stop process, the metal strip 16 reduces its diameter under the pull of the motor 14, which provides a comprehensive and tight friction effect on the outer surface of the rotating shaft 7. That is, friction is applied to the entire outer surface of the rotating shaft 7, thereby effectively reducing speed and braking.

[0083] Once the emergency has been resolved, the equipment needs to be restored to normal cutting operation. The specific reset process is as follows:

[0084] The controller sends an extension control signal to the second cylinder 19, and the extension end of the second cylinder 19 extends upward. The extension end of the second cylinder 19 pushes the bottom of the mounting plate 17 upward, causing the mounting plate 17 to slide upward along the limiting slide 18.

[0085] As the mounting plate 17 moves upward, it drives the motor 14, the second bevel gear 15, and the metal strip 16 to move upward synchronously. When the mounting plate 17 moves to the top limit position of the limiting slide 18, it is limited by the limiting block and cannot move upward further. At this time, the second bevel gear 15 and the first bevel gear 13 return to a fully meshed state.

[0086] As the mounting plate 17 moves upward, both ends of the metal strip 16 move upward together with the motor 14. The diameter of the ring structure formed by the metal strip 16 gradually returns to its initial size. When the mounting plate 17 reaches the top limit position, the metal strip 16 completely returns to its initial state under the action of its own elastic restoring force. A gap is re-formed between the inner wall of the ring structure and the outer circular surface of the rotating shaft 7, and the two no longer contact each other.

[0087] After the mounting plate 17 reaches its top limit position, the second cylinder 19 is kept in its current extended state, and the equipment returns to its initial state, allowing normal cutting operations to continue.

[0088] During the cutting process of automotive parts by the cutting blade 8, a large amount of metal chips are generated. Some of these chips fall into the housing 10 located outside the cutting blade 8 under the action of centrifugal force and gravity.

[0089] Debris falling into the housing 10 slides down the inner wall of the housing 10 and gathers at the discharge port 11 at the bottom of the housing 10, and then is discharged from the housing 10 through the discharge port 11. The debris discharged from the discharge port 11 falls into the collection box 12 located below the discharge port 11 under the action of gravity.

[0090] After the collection box 12 collects a certain amount of debris, it can be cleaned regularly by the operator, and the debris in the collection box 12 can be dumped into the designated waste treatment area to achieve centralized treatment of debris and clean production in the workshop.

[0091] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
