Description

Technical Field

[0001] This invention relates to the field of intelligent processing technology for automotive parts, and in particular to an automated cutting device for processing automotive parts. Background Technology

[0002] Automotive pipes are a general term for various pipes in a car. Their core function is to deliver working media in a directional manner, thereby realizing functions such as oil supply, lubrication, and cooling of the engine. They are fundamental components that ensure the power and safety of the entire vehicle. Automotive pipes undertake critical tasks such as delivering fuel, brake fluid, coolant, or gas. They need to maintain absolute sealing under high pressure, vibration, and temperature difference changes. Therefore, in order to ensure that the pipe opening size is accurate, the end face is vertical and burr-free, and that subsequent flaring, welding, or compression fitting can achieve the design strength and zero leakage, automotive pipes need to be precisely cut to ensure the reliability and safety of the pipeline in the dense engine compartment.

[0003] Currently, the following problems still exist when using a disc cutter to cut automotive pipes: Before cutting the automotive pipes, the pipes are only clamped from the outside, and the cutting force can cause the pipe wall to be concave, elliptical, or burr-like, affecting the roundness of the cut and the accuracy of subsequent assembly. Moreover, there is no internal support structure inside the pipe, which leads to uneven force on the inner and outer walls of the pipe during cutting, resulting in excessive vibration of the pipe and easily causing problems such as cut deviation or abnormal wear of the tool. At the same time, the metal shavings produced by cutting will fly and remain in the pipe cavity, requiring additional cleaning processes later, which makes it difficult to meet the cleanliness requirements of automotive parts and affects the reliability of the piping system. Summary of the Invention

[0004] In view of the problem of lack of internal support when using a disc cutter to cut automotive pipe parts in the above or existing technologies, the present invention is proposed.

An internal fixation mechanism is set inside the external fixation mechanism; the internal fixation mechanism includes a movable outer shell set between the arc-shaped clamping blocks, a movable component and a cooperating magnetic block are provided on the movable outer shell, the movable outer shell and the electromagnetic block are magnetically engaged and follow the arc-shaped clamping blocks to move in the tube, and a number of internal expansion rods are arranged in a circumferential array inside the movable outer shell, and a barrier cover is provided between the internal expansion rods. The chip suction mechanism is mounted on the movable housing and support frame; the cutting assembly cuts the pipe fittings, and the inner and outer expansion rods simultaneously squeeze the inner and outer ring walls of the pipe fittings at the cutting point, while the barrier cover unfolds following the inner expansion rod.

[0006] Preferably, the cutting assembly includes a lifting plate fixedly installed on the cutting machine body and located directly below the support frame, a hydraulic telescopic rod with its telescopic end fixedly connected to the lifting plate fixedly installed on the cutting machine body, and a cutting disc rotatably installed on the lifting plate.

[0007] Preferably, the upper surface of the cutting machine body is fixedly installed with guide rails corresponding to the positioning sliders, a fixing block is fixedly installed on the positioning slider, a first telescopic rod with its telescopic end fixedly connected to the arc-shaped clamping block is fixedly installed on the fixing block, and a first positioning rod fixedly connected to the arc-shaped clamping block is slidably installed through the fixing block.

[0008] Preferably, the end of the outer expansion rod away from the corresponding arc-shaped clamping block is hinged to a first contact block by a torsion spring. A pneumatic telescopic rod corresponding to the outer expansion rod is fixedly installed on the arc-shaped clamping block, and the end of the pneumatic telescopic rod away from the corresponding arc-shaped clamping block is hinged to the corresponding outer expansion rod.

[0009] Preferably, the inner wall of the arc-shaped clamping block is fixedly mounted with a second contact block in a circumferential array by a set spring.

[0010] Preferably, the external fixing mechanism further includes a locking assembly for locking the two arc-shaped clamping blocks. The locking assembly includes a rod fixedly installed on one side of the arc-shaped clamping block, with a through-hole on the rod. The corresponding arc-shaped clamping block on the other side has a corresponding insertion hole and a second telescopic rod is fixedly installed thereon. The telescopic end of the second telescopic rod is fixedly installed with a locking rod that engages with the insertion hole.

[0011] Preferably, the movable component includes a central rod fixedly installed at the center of the interior of the movable housing. Several supporting horizontal plates are hinged in a circular array on the outer ring wall of the central rod via a first hinge plate. Symmetrical rollers are rotatably installed on the supporting horizontal plates. A sliding sleeve is slidably fitted on the outer ring wall of the central rod via a spring. The sliding sleeve is hinged to the first hinge plate via a second hinge plate. A third telescopic rod is fixedly installed inside the movable housing. The telescopic rod of the third telescopic rod is fixedly connected to the sliding sleeve.

[0012] Preferably, the movable outer shell has a groove at the end away from the corresponding central rod that corresponds to the inner expansion rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by simultaneously squeezing the inner and outer ring walls of the cutting area by the outer and inner fixing mechanisms, a double support is formed, which avoids flattening or deformation of thin-walled automotive pipes during the cutting process. Moreover, the rigid squeezing of the inner and outer parts increases the local structural rigidity, reduces the vibration and tremors during the cutting process, and makes the cutting more stable, improving the quality and dimensional accuracy of the cut surface. In addition, with the magnetic cooperation of the magnetic block and the electromagnetic block, the inner fixing mechanism can automatically follow the outer fixing mechanism to move along the inside of the pipe to the cutting position, improving the efficiency and reliability of automated cutting. At the same time, the barrier cover unfolds to form a local shielding space in the cutting area, which, together with the chip suction mechanism, concentrates and collects the chips and dust, preventing chips from splashing and polluting the working environment. Therefore, it is suitable for automotive pipe cutting operations with high requirements for roundness, cross-sectional quality and cleanliness. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 An automated cutting device for processing automotive parts includes a cutting machine body 1, a support frame 3 mounted thereon, and a cutting assembly 2. The cutting machine body 1 is provided with two sets of external fixing mechanisms 4 symmetrical about the cutting assembly 2. The external fixing mechanism 4 includes a positioning slider 41 symmetrically slidably mounted on the upper end face of the cutting machine body 1. The positioning slider 41 is provided with an arc-shaped clamping block 42. The arc-shaped clamping blocks 42 clamp automotive parts close to each other. The inner wall of the arc-shaped clamping block 42 is hinged with a plurality of external expansion rods 43 in a circumferential array. An electromagnetic block 44 is fixedly mounted on the arc-shaped clamping block 42.

[0030] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8 The inner fixing mechanism 5 is located inside the outer fixing mechanism 4. The inner fixing mechanism 5 includes a movable outer shell 51 located between the arc-shaped clamping blocks 42. The movable outer shell 51 is provided with a movable component 52 and a cooperating magnetic block 55. The movable outer shell 51 and the electromagnetic block 44 are magnetically engaged and move in the tube following the arc-shaped clamping block 42. A number of inner expansion rods 53 are arranged in a circumferential array inside the movable outer shell 51. A barrier cover 54 is provided between the inner expansion rods 53.

[0031] The chip suction mechanism 6 is mounted on the movable housing 51 and the support frame 3; the cutting assembly 2 cuts the pipe, and the inner expansion rod 53 and the outer expansion rod 43 simultaneously squeeze the inner and outer ring walls of the pipe at the cutting point, and the barrier cover 54 unfolds following the inner expansion rod 53.

[0032] In actual operation, the two sets of external fixing mechanisms 4 are respectively installed on both sides of the support frame 3. The inner surface of the arc-shaped clamping block 42 is an arc shape that matches the outer diameter of the pipe fitting, thereby clamping or releasing the automotive pipe fitting. When the arc-shaped clamping block 42 clamps the pipe fitting, the outer expansion rod 43 provides support force from the outer wall of the pipe fitting inward. The electromagnetic block 44 generates a magnetic field and generates attraction with the matching magnetic block 55 inside the pipe fitting. Through the mutual attraction between the two, the linkage between the inner and outer mechanisms is realized.

[0033] The internal fixation mechanism 5 corresponds to and cooperates with the external fixation mechanism 4 on one side. The internal fixation mechanism 5 is an independent unit. After the pipe is clamped by the external fixation mechanism 4, the mechanical arm is inserted into the pipe and its position is adjusted. The free end of the internal expansion rod 53 is pushed outward and abuts against the inner wall of the pipe. The barrier cover 54 is connected between the internal expansion rods 53 by a hinge.

[0034] Before the cutting assembly 2 cuts the pipe, the external fixing mechanism 4 is fixed on both sides of the pipe cutting part. At this time, the inner expansion rod 53 and the outer expansion rod 43 simultaneously squeeze the inner and outer ring walls of the pipe cutting part. At the same time, the barrier cover 54 unfolds with the inner expansion rod 53 to form a closed area. Then the cutting assembly 2 cuts the pipe. During the cutting, the chip suction mechanism 6 sucks up the debris in the pipe and connects it to the external vacuuming equipment through another hose.

[0035] This achieves uniform support and compression of the inner and outer ring walls within the cutting area of ​​the automotive pipe fitting, suppressing deformation and vibration of the pipe wall during the cutting process. At the same time, the barrier cover 54 inside the inner fixing mechanism 5 works in conjunction with the chip suction mechanism 6 to form a closed chip collection environment during cutting and remove the generated metal chips in real time, thereby avoiding chip splashing and residue, ensuring the roundness and perpendicularity of the pipe fitting cut and the cleanliness of the pipe cavity, and improving the accuracy of subsequent assembly and the reliability of the pipeline system.

[0036] Please see Figure 1 and Figure 4 The cutting assembly 2 includes a lifting plate 22 fixedly installed on the cutting machine body 1 and located directly below the support frame 3. A hydraulic telescopic rod 21 with its telescopic end fixedly connected to the lifting plate 22 is fixedly installed on the cutting machine body 1. A cutting disc 23 is rotatably installed on the lifting plate 22.

[0037] In actual operation, the hydraulic telescopic rod 21 enables the cutting disc 23 to achieve precise and stable vertical lifting and lowering through hydraulic drive, thereby effectively controlling the cutting depth, avoiding pipe deformation caused by uneven cutting depth, and ensuring that the cutting force can be applied to the pipe evenly.

[0038] Therefore, when cutting pipe fittings, it is only necessary to activate the hydraulic telescopic rod 21 to control the lifting plate 22 to raise and lower, thereby controlling the cutting disc 23 to cut the pipe fittings.

[0039] Please see Figure 2 and Figure 3 The upper end face of the cutting machine body 1 is fixedly installed with guide rails 411 corresponding to the positioning sliders 41. A fixing block 412 is fixedly installed on the positioning sliders 41. A first telescopic rod 413 with its telescopic end fixedly connected to the arc-shaped clamping block 42 is fixedly installed on the fixing block 412. A first positioning rod 414 fixedly connected to the arc-shaped clamping block 42 is slidably installed through the fixing block 412.

[0040] In actual operation, the guide slide rail 411 drives the positioning slider 41 to slide inside it, and the guide slide rail 411 ensures that the positioning slider 41 always moves smoothly along the preset straight trajectory when adjusting the position. When fixing the pipe fitting with the external fixing mechanism 4, the cutting position can be adjusted by the movement of the positioning slider 41.

[0041] The first telescopic rod 413 achieves telescopic movement by driving a ball screw with a motor. It is used to adjust the clamping distance between the arc-shaped clamping block 42 and the pipe and the applied clamping force, so that the arc-shaped clamping block 42 can apply a stable clamping force. Meanwhile, the first positioning rod 414 ensures that the arc-shaped clamping block 42 maintains a precise posture during telescopic and clamping processes.

[0042] When the pipe is placed on the cutting machine body 1, the corresponding positioning sliders 41 on both sides will move to the corresponding position of the pipe. At this time, the first telescopic rods 413 on both sides will synchronously drive the arc-shaped clamping block 42 to approach the pipe, thereby clamping the pipe. When the pipe is moved to the cutting size, the external fixing mechanism 4 on the other side will fix the other side of the pipe.

[0043] This improves the clamping stability and positioning accuracy of the external fixing mechanism for automotive pipe parts, prevents vibration and deformation of the pipe parts during cutting, ensures cutting accuracy and cut quality, and improves the reliability of automotive parts processing.

[0044] Please see Figure 2 , Figure 5 and Figure 6 The end of the outer expansion rod 43 away from the corresponding arc-shaped clamping block 42 is hinged to the first contact block 431 by a torsion spring. The arc-shaped clamping block 42 is fixedly installed with a pneumatic telescopic rod 432 that corresponds one-to-one with the outer expansion rod 43. The end of the pneumatic telescopic rod 432 away from the corresponding arc-shaped clamping block 42 is hinged to the corresponding outer expansion rod 43.

[0045] In actual operation, the torsion spring allows the first contact block 431 to adjust its angle or position when contacting the pipe to achieve flexible contact and buffering, and evenly distribute the clamping pressure acting on the pipe. The pneumatic telescopic rod 432 can provide adjustable driving force and precisely control the position and clamping force of the outer expansion rod 43.

[0046] When the arc-shaped clamping block 42 completes clamping of the pipe fitting, the arc-shaped clamping block 42 is positioned close to the cutting disc 23. Then, the pneumatic telescopic rod 432 is activated to push the free end of the outer expansion rod 43 toward the outer ring wall of the pipe fitting to be cut, until the outer expansion rod 43, along with the first contact block 431, squeezes the outer ring wall of the pipe fitting to be cut. This improves the clamping stability and adaptability of the outer fixing mechanism 4 for automotive pipe fittings, suppresses problems such as concave or elliptical deformation of the pipe wall or the generation of burrs during the cutting process, ensures the roundness of the cut and the subsequent assembly accuracy, and ultimately improves the quality and efficiency of automotive parts processing.

[0047] Please see Figure 2 , Figure 5 and Figure 6 The inner wall of the arc-shaped clamping block 42 is fixedly mounted with a second contact block 45 by a set spring in a circumferential array.

[0048] In actual operation, the second contact block 45 serves as an additional contact point, working in conjunction with the first contact block 431 on the outer expansion rod 43 to form a multi-point support clamping structure, increasing the contact area with the pipe. In addition, through the elastic action of the spring, the second contact block 45 can adaptively conform to the shape of the pipe and effectively absorb the impact and vibration generated during the cutting process, thereby significantly reducing the shaking and deformation of the pipe during the cutting process.

[0049] Please see Figure 2 and Figure 5 The external fixing mechanism 4 also includes a locking assembly 46 for locking the two arc-shaped clamping blocks 42. The locking assembly 46 includes a plug rod 461 fixedly installed on one side of the arc-shaped clamping block 42, with a through-hole 462 on the plug rod 461. The corresponding arc-shaped clamping block 42 on the other side has a corresponding insertion hole and a second telescopic rod 464 fixedly installed thereon. The telescopic end of the second telescopic rod 464 is fixedly installed with a locking rod 463 that engages with the insertion hole 462.

[0050] In actual operation, after the automotive pipe is clamped in place by the arc-shaped clamping block 42 of the external fixing mechanism 4, the insertion rod 461 on the arc-shaped clamping block 42 is inserted into the insertion hole on the other side of the arc-shaped clamping block 42. At this time, the second telescopic rod 464 drives the locking rod 463 to extend and insert it into the insertion port 462 on the insertion rod 461, locking the arc-shaped clamping blocks 42 on both sides, enhancing the stability and reliability of clamping. When the cutting component 2 performs high-speed cutting on the automotive pipe, the locking component 46 can also ensure that the arc-shaped clamping block 42 will not loosen or shift, thereby avoiding problems such as concave or elliptical deformation or cutting deviation of the pipe due to insecure clamping.

[0051] Please see Figure 7 and Figure 8 The movable component 52 includes a central rod 521 fixedly installed at the center of the interior of the movable housing 51. Several supporting horizontal plates 522 are hinged in a circular array on the outer ring wall of the central rod 521 through a first hinge plate. Symmetrical rollers 523 are rotatably installed on the supporting horizontal plates 522. A sliding sleeve 524 is slidably fitted on the outer ring wall of the central rod 521 through a spring. The sliding sleeve 524 is hinged to the first hinge plate through a second hinge plate. A third telescopic rod 525 is fixedly installed inside the movable housing 51. The telescopic rod of the third telescopic rod 525 is fixedly connected to the sliding sleeve 524.

[0052] In actual operation, when the movable outer shell 51 enters the pipe, the third telescopic rod 525 is activated to push the sliding sleeve 524 to move along the central rod 521. The axial movement of the sliding sleeve 524 changes the angle of the first hinge plate, thereby controlling the support horizontal plate 522 to expand or contract around the central rod 521, ensuring that the support horizontal plate 522 can flexibly adapt to the inner wall of pipes of different diameters. The roller 523 can ensure the smooth sliding of the movable outer shell 51 in the pipe, so that the movable outer shell 51 can move to the corresponding position in the pipe by following the arc-shaped clamping block 42 through the magnetic cooperation between the magnetic block 55 and the electromagnetic block 44.

[0053] Please see Figure 7 and Figure 8 The movable housing 51 has a groove 532 at one end away from the corresponding center rod 521 that corresponds to the inner expansion rod 53. A sliding groove 533 is provided through the inner expansion rod 53. A pin is provided in the groove 532 that is slidably connected to the sliding groove 533. A fourth telescopic rod 535 is fixedly installed inside the movable housing 51. A movable disk 534 is fixedly installed at the telescopic end of the fourth telescopic rod 535. The inner expansion rod 53 is hinged to the movable disk 534.

[0054] Please see Figure 7 and Figure 8 The end of the inner expansion rod 53 away from the movable outer shell 51 is hinged to a third contact block 531 by a torsion spring. The surfaces of the first contact block 431, the second contact block 45 and the third contact block 531 are covered with a rubber layer.

[0055] In actual operation, when the movable housing 51 moves to the corresponding position, the fourth telescopic rod 535 drives the movable disk 534 fixed at its telescopic end to move linearly. Since the inner expansion rod 53 is hinged to the movable disk 534, the inner expansion rod 53 will rotate around its hinge point and, with the cooperation of the pin and the slide groove 533, smoothly expand outward or contract inward along the trajectory of the groove 532. Therefore, before cutting, the inner expansion rod 53 will carry the third contact block 531 to provide internal support to the inner ring wall of the part to be processed inside the pipe, thereby providing more reliable and uniform support and fixation, suppressing the concave or elliptical deformation or vibration of the pipe under the action of cutting force, improving the cutting accuracy and stability, reducing the generation of burrs, and extending the service life of the tool.

[0056] The rubber layer covering the surfaces of the first contact block 431, the second contact block 45, and the third contact block 531 further ensures flexibility when in contact with the pipe fitting, thereby preventing the contact blocks from damaging the surface of the pipe fitting and suppressing the generation of additional debris during the cutting process.

[0057] Please see Figure 2 and Figure 9The dust collection mechanism 6 includes a dust collection frame 62 symmetrically installed inside the support frame 3. Several air outlets 61 are fixedly installed on one side of the movable housing 51 in a circumferential array. The several air outlets 61 are connected by an air supply pipe 611.

[0058] In actual operation, the chip suction frame 62 is a box with a porous structure connected to an external negative pressure source, which creates negative pressure in the cutting area to suck in and trap the flying debris inside the frame. The air outlet 61 sprays a uniform airflow to thoroughly blow away the pipe wall, ensuring that the debris is effectively stripped off. The air supply pipe 611 is used to distribute the air source to each air outlet 61 to ensure the uniformity and stability of the airflow.

[0059] When the cutting assembly 2 cuts the pipe, the chip suction frame 62 sucks up the externally splashed debris, the movable housing 51 extends into the inside of the pipe, and the air outlet 61 blows the inner wall of the pipe to discharge the internal debris from the pipe cavity.

[0060] The inner expansion rod 53 and the outer expansion rod 43 simultaneously squeeze the inner and outer ring walls of the pipe cutting area. The barrier cover 54 unfolds along with the inner expansion rod 53, forming a relatively closed cutting environment. The chip suction mechanism 6 works simultaneously inside and outside in this environment, which can more thoroughly remove chips and solve the problem of insufficient cleanliness caused by chip residue in traditional cutting methods, avoiding additional cleaning processes.

[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
