[0001] The present invention belongs to the technical field of metal cutting, and particularly relates to a pipe cutting machine for the production of mechatronic vehicle frames. Background Art

[0002] In the modern vehicle frame production process, the precise cutting of pipes is one of the key steps in manufacturing high-quality vehicle frames. Traditional pipe cutting methods mainly rely on manual operation, which is not only inefficient but also difficult to ensure cutting accuracy and consistency, especially when dealing with pipes of complex angles and different sizes. With the increasing requirements for automation and intelligence in the manufacturing industry, traditional cutting methods can no longer meet the high standards of modern vehicle frame production.

[0003] In addition, there are various types of pipes used in vehicle frame production, and the raw pipes need to be cut into specific lengths and angles to meet different design requirements. This requires the cutting equipment to have a high degree of flexibility and adaptability so that it can quickly adjust and accurately execute various cutting tasks. However, most existing cutting machines can only perform straight-line cutting in a single direction. For situations that require multi-angle and multi-directional cutting, tools need to be frequently replaced or equipment settings adjusted, which greatly limits production efficiency and increases operation difficulty and costs.

[0004] Therefore, in view of the above current situation, there is an urgent need to develop a pipe cutting machine for the production of mechatronic vehicle frames to overcome the deficiencies in current practical applications. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0022] As Figure 1 shown, a pipe cutter for the production of a mechatronic vehicle frame according to an embodiment of the present invention includes a centering and bearing unit 10 for centering and bearing a pipe, and further includes: A pipe cutting unit 30 mounted and fixed on the centering and bearing unit 10 for cutting the pipe at a specified angle; A pipe pushing unit 20 adjustably mounted on the centering and bearing unit 10, the pipe pushing unit 20 being used for intermittently pushing the pipe and keeping the pipe in a stable state when the pipe cutting unit 30 cuts the pipe; An auxiliary positioning unit 40 adjustably mounted on the centering and bearing unit 10, the pipe cutting unit 30 being located between the pipe pushing unit 20 and the auxiliary positioning unit 40, the auxiliary positioning unit 40 being used for cooperating with the pipe pushing unit 20 to perform cutting positioning on the pipe.

[0023] In the embodiment of the present invention, the centering and bearing unit 10 for centering and bearing the pipe is provided with the pipe pushing unit 20 and the auxiliary positioning unit 40. The pipe pushing unit 20 can intermittently push the pipe and keep the pipe in a stable state when the pipe cutting unit 30 cuts the pipe. Moreover, the auxiliary positioning unit 40 cooperates with the pipe pushing unit 20 to perform cutting positioning on the pipe, so that the cutting position of the pipe is accurate and the pipe is in a stable state during cutting, thereby improving the cutting accuracy and efficiency. In addition, the pipe cutting unit 30 can meet the requirement of cutting the pipe at a specified angle, and is suitable for processing pipes with different cross-sections required for vehicle frame production, and has a wide range of applications.

[0024] As Figure 1-4As shown, as a preferred embodiment of the present invention, the pipe fitting cutting unit 30 includes an assembly frame two 302 fixed on the central bearing unit 10. A cutting telescopic cylinder 301 is fixed in the middle of the assembly frame two 302. A direction adjusting seat 303 is rotatably installed at the end of the telescopic rod of the cutting telescopic cylinder 301. A worm shaft 315 perpendicular to the telescopic rod of the cutting telescopic cylinder 301 is rotatably installed in the direction adjusting seat 303. A worm 316 is fixed on the worm shaft 315. A worm gear 314 meshing with the worm 316 is fixed on the telescopic rod of the cutting telescopic cylinder 301. One end of the worm shaft 315 is drivingly connected to a direction adjusting motor 313, and a knob 311 is fixed at the other end of the worm shaft 315. A cutting bracket 306 is fixed on the lower side of the direction adjusting seat 303. A cutting motor 307 is fixed at the lower end of the cutting bracket 306. The output shaft of the cutting motor 307 is parallel to the worm shaft 315. A cutting wheel 304 is detachably fixed on the output shaft of the cutting motor 307.

[0025] Preferably, the assembly frame two 302 adopts an inverted U-shaped structure, and the lower ends of the two branches of the assembly frame two 302 are both fixedly connected to the central bearing unit 10.

[0026] Preferably, the direction adjusting seat 303 adopts a side-mounted U-shaped structure. Shaft support plates 317 are also fixed at the openings on both sides of the direction adjusting seat 303. The two ends of the worm shaft 315 are rotatably connected to the shaft support plates 317. The direction adjusting motor 313 is fixed on the shaft support plates 317. The telescopic rod of the cutting telescopic cylinder 301 is rotatably connected to both branches on both sides of the direction adjusting seat 303, improving reliability.

[0027] Preferably, an angle scale 309 is provided on the top of the direction adjusting seat 303 outside the telescopic rod of the cutting telescopic cylinder 301. A pointer 310 cooperating with the angle scale 309 is also fixed on the telescopic rod of the cutting telescopic cylinder 301, facilitating the indication of the direction adjustment angle. The worm gear 314 and the worm shaft 315 itself have self-locking performance. After adjusting the direction by selecting the knob 311 or the direction adjusting motor 313 as needed, a stable state can be maintained. To further improve reliability, a fixing bolt 312 for locking and fixing it on the telescopic rod of the cutting telescopic cylinder 301 is also installed on the direction adjusting seat 303.

[0028] Calculation of the transmission ratio of the worm gear 314 and the worm 316 for cutting angle adjustment: ; Among them, θ is the angle of the cutting wheel 304, L is the lead of the worm 316, r is the radius of the worm gear 314, and Z1 and Z2 are the number of teeth of the worm 316 and the worm gear 314 respectively.

[0029] Preferably, a positioning ring 305 for limiting the cutting wheel 304 is fixed on the output shaft of the cutting motor 307 on the side of the direction adjustment seat 303 away from the cutting motor 307. A locking nut 308 for locking and fixing the cutting wheel 304 is also threadedly connected to the output shaft of the cutting motor 307. The stable and reliable operation of the cutting wheel 304 can be ensured by the cooperation of the locking nut 308 and the positioning ring 305.

[0030] Due to the structural limitation of the pipe cutting unit 30, the direction adjustment is convenient, reliable, and highly accurate. By driving the cutting wheel 304 to move up and down with the cutting telescopic cylinder 301, the pipe can be reliably cut.

[0031] Such as Figure 1 and 5 As shown in the figure, as a preferred embodiment of the present invention, the pipe pushing unit 20 includes an assembly frame one 201 that is adjustably and movably installed on the central bearing unit 10. A regulating telescopic cylinder two 204 is fixed in the middle of the assembly frame one 201. The end of the telescopic rod of the regulating telescopic cylinder two 204 is fixed with an assembly plate 205. One end of the assembly plate 205 is fixed with a pushing motor 206. Rotating plates 207 are fixed on both output shafts on both sides of the pushing motor 206. A pushing plate 209 is hinged to the end of the rotating plate 207 away from the pushing motor 206. An auxiliary plate 208 is also hinged to the pushing plate 209. The end of the auxiliary plate 208 away from the pushing plate 209 is hinged to the end of the assembly plate 205 away from the pushing motor 206. A pushing block 210 is hinged between the ends of the two pushing plates 209 away from the rotating plate 207. An elastic block 211 is installed and fixed on the lower side of the pushing block 210.

[0032] Preferably, the assembly frame one 201 adopts an inverted U-shaped structure. The lower ends of the two branches of the assembly frame one 201 are both slidably connected to the adjustment track one 202 fixed on the central bearing unit 10. A regulating telescopic cylinder one 203 is also fixed on the central bearing unit 10. The end of the telescopic rod of the regulating telescopic cylinder one 203 is fixedly connected to the assembly frame one 201. By the telescopic movement of the regulating telescopic cylinder one 203, the assembly frame one 201 can be driven to move relative to the pipe cutting unit 30.

[0033] Preferably, the bottom of the elastic block 211 has an upwardly concave arc structure in the middle, and an anti-slip layer is also provided on the bottom of the elastic block 211, which can limit the pipe and ensure the reliability of the pushing and pressing.

[0034] Preferably, the circular motion of the rotating plate 207 causes the auxiliary plate 208 and the pushing plate 209 to swing and move accordingly. Under the combined action of the auxiliary plate 208 and the rotating plate 207, the movement trajectory of the end of the pushing plate 209 is the result of the synthesis of the movements of the auxiliary plate 208 and the rotating plate 207, enabling the end of the pushing plate 209 to achieve an approximately horizontal linear motion, thereby being able to push the pipe fitting, forming a cycle of pressing the pipe fitting → pushing the pipe fitting → releasing the pipe fitting → returning to the original position... and so on, with an intermittent feeding effect. The lengths of the rotating plate 207, the auxiliary plate 208, and the pushing plate 209 can be adjusted and / or the hinged positions between the rotating plate 207 and the pushing plate 209, and between the auxiliary plate 208 and the pushing plate 209 can be adjusted, thereby adjusting the distance that the elastic block 211 pushes the pipe fitting. For example: when the hinged position between the rotating plate 207 and the pushing plate 209 is adjusted, the force arm of the rotating plate 207 on the pushing plate 209 changes when the rotating plate 207 rotates, the horizontal displacement of the end of the pushing plate 209 changes, and the distance of pushing the pipe fitting changes.

[0035] Through the structural limitation of the pipe fitting pushing unit 20, the pushing motor 206 drives the rotating plate 207, and with the structural design of the auxiliary plate 208 and the pushing plate 209, the pushing block 210 and the elastic block 211 cooperate to have an intermittent feeding effect of pressing → pushing → releasing → returning to the original position... and so on, with the pushing distance adjustable, and with the settings of the adjusting telescopic cylinder two 204 and the adjusting telescopic cylinder one 203, it adapts to different models of pipe fittings and scenarios, achieving a more reliable feeding effect.

[0036] As Figure 1 and 5 shown, as a preferred embodiment of the present invention, the auxiliary positioning unit 40 includes an assembly frame three 402 that is adjustably and movably installed on the central bearing unit 10. A regulating telescopic cylinder three 401 is fixed in the middle of the assembly frame three 402, and a positioning switch 403 for positioning the pipe fitting is fixed at the end of the telescopic rod of the regulating telescopic cylinder three 401. Just adapt and adjust the pushing of the pipe fitting pushing unit 20 and the positioning of the auxiliary positioning unit 40, so that the pipe fitting pushing unit 20 just triggers the positioning switch 403 after pushing the pipe fitting. Specifically: when the positioning switch 403 is triggered by the pipe fitting, the pipe fitting cutting unit 30 performs a cutting operation on the pipe fitting.

[0037] Preferably, the assembly frame three 402 adopts an inverted U-shaped structure. The lower ends of the two branches of the assembly frame three 402 are both slidably connected to the adjusting track two 404 fixed on the central bearing unit 10. An adjusting telescopic cylinder four 405 is also fixed on the central bearing unit 10, and the end of the telescopic rod of the adjusting telescopic cylinder four 405 is fixedly connected to the assembly frame three 402. By the telescopic action of the adjusting telescopic cylinder four 405, the position of the assembly frame three 402 relative to the pipe fitting cutting unit 30 can be driven to move.

[0038] Preferably, an optoelectronic sensor 50 for detecting whether the pipe cutting unit 30 has finished cutting is also installed on the centering and bearing unit 10. After the pipe cutting unit 30 finishes cutting the pipe, the adjusting telescopic cylinder three 401 of the auxiliary positioning unit 40 shortens to avoid the positioning switch 403. At the same time, the pipe pushing unit 20 starts a new round of pipe pushing action. After the cut pipe is separated from the pipe to be cut (for example, the cut pipe falls into the storage box), the adjusting telescopic cylinder three 401 of the auxiliary positioning unit 40 elongates, and the positioning switch 403 re - positions the pipe; this cycle repeats to achieve continuous positioning and cutting.

[0039] In addition, the control of each component can use a PLC controller disclosed in the prior art. The models and circuit connections of each component are not specifically limited and can be flexibly set in actual applications. The circuits, electronic components, and modules involved are all prior art and can be fully realized by those skilled in the art without further elaboration. The content protected by the present invention does not involve improvements to software and methods. For example, the optoelectronic sensor 50 generally includes a transmitter and a receiver, which are distributed on both sides of the cutting wheel 304. When the cutting wheel 304 passes through, if it completely cuts the pipe, it will briefly block the light beam, so that it can be judged whether the cutting is completed. The optoelectronic sensor 50 will send a signal to the controller. After receiving this signal, the controller can make corresponding reactions according to the preset program logic, such as the adjusting telescopic cylinder three 401 of the auxiliary positioning unit 40 shortening to avoid the positioning switch 403, and at the same time the pipe pushing unit 20 starting a new round of pipe pushing action, etc., which will not be elaborated here.

[0040] Through the limitation of the auxiliary positioning unit 40 and the optoelectronic sensor 50, a better positioning effect can be achieved and the mechatronics level of the device can be improved. It should be noted that even if there is a certain deviation in the cooperation between the pipe pushing unit 20 and the auxiliary positioning unit 40, the elastic structure of the elastic block 211 and the misaligned sliding between the elastic block 211 and the pipe can be used to meet the actual use requirements.

[0041] Such as Figure 1 、 2 As shown in FIGS. 5 and 6, as a preferred embodiment of the present invention, the centering and bearing unit 10 includes two horizontally and parallelly arranged side bearing frames 101. A reinforcing plate 105 is fixedly spanned and arranged below between the two side bearing frames 101. A plurality of legs 104 are also fixedly arranged on the lower sides of the two side bearing frames 101. A number of bearing shafts 102 are evenly distributed and fixedly arranged on both sides between the two side bearing frames 101. A bearing roller 103 with a middle arc concave inward is rotatably installed on the bearing shafts 102.

[0042] Preferably, the two branches on both sides of the assembly frame two 302 of the pipe fitting cutting unit 30 are fixedly connected to the middle parts of the two side bearing frames 101 correspondingly, so that the cutting wheel 304 is in a proper position, the cutting wheel 304 will not touch the carrying roller 103, and the cutting requirement is satisfied. The photoelectric sensor 50 is fixedly arranged in the middle of the inner side of the side bearing frame 101. The first adjusting track 202 and the second adjusting track 404 are fixedly arranged on the side bearing frame 101 correspondingly, and the first adjusting telescopic cylinder 203 and the fourth adjusting telescopic cylinder 405 are also fixedly arranged on the side bearing frame 101 correspondingly, meeting the requirement of stably driving the first assembly frame 201 and the third assembly frame 402.

[0043] Through the limitation of the central bearing unit 10, especially the structural arrangement of the carrying roller 103, the pipe fitting can be centrally supported, and it is adapted to the elastic block 211 to push the pipe fitting, and the overall structure is reasonable and reliable.

[0044] In addition, the carrying roller 103 is made of high-strength alloy steel, the surface is treated with hard chromium plating, the diameter range is 50-150 mm, and it is adapted to the outer diameter of the pipe fitting of 20-200 mm. The cutting wheel 304 adopts a diamond-coated blade with a thickness of 2-5 mm, and the adjustable range of the cutting linear speed is 10-50 m / s.

[0045] A protective cover (not shown) can be installed around the cutting wheel 304 of the pipe fitting cutting unit 30 as required. The protective cover is linked with the cutting motor 307 through a magnetic sensor. When the protective cover is not closed, the cutting motor 307 will automatically cut off the power supply.

[0046] In the above embodiments of the present invention, a pipe fitting cutting machine for the production of a mechatronic vehicle frame is provided, and the working principle is as follows: The central bearing unit 10 centrally supports the pipe fitting through two parallel side bearing frames 101 and a carrying roller 103 with a middle arc concave inward, ensuring its stability during the pushing and cutting processes.

[0047] The pipe fitting pushing unit 20 uses the second adjusting telescopic cylinder 204 on the first assembly frame 201 to drive the moving of the assembly plate 205. The pushing motor 206 installed on the assembly plate 205 realizes the intermittent pushing of the pipe fitting through the linkage structure of the rotating plate 207, the auxiliary plate 208 and the pushing plate 209. The elastic block 211 is located under the pushing block 210 and is used for pressing and pushing the pipe fitting forward, and ensures that the pushing distance is adjustable.

[0048] The auxiliary positioning unit 40 includes a third assembly frame 402, in the middle of which a third adjusting telescopic cylinder 401 is fixed, and the end of its telescopic rod is fixed with a positioning switch 403 for positioning the pipe fitting. When the pipe fitting is pushed to trigger the positioning switch 403, the pipe fitting cutting unit 30 starts to perform the cutting operation on the pipe fitting.

[0049] The pipe fitting cutting unit 30 includes an assembly frame two 302 fixed on the central bearing unit 10. A cutting telescopic cylinder 301 is provided in the middle of the assembly frame two 302, and a direction adjusting seat 303 is rotatably installed at the end of its telescopic rod. Inside the direction adjusting seat 303, there is a worm shaft 315 perpendicular to the telescopic rod of the cutting telescopic cylinder 301. A worm 316 is fixed on the worm shaft 315, and a worm gear 314 meshing with the worm 316 is fixed on the telescopic rod of the cutting telescopic cylinder 301. In addition, a cutting bracket 306 is fixed below the direction adjusting seat 303, and a cutting motor 307 is installed at its lower end. A cutting wheel 304 is installed on the output shaft of the cutting motor 307.

[0050] The photoelectric sensor 50 is fixed in the middle inside the side bearing frame 101 and is used to detect whether the pipe fitting is completely cut. After cutting is completed, the photoelectric sensor 50 sends a signal to the controller, and the controller controls the adjusting telescopic cylinder three 401 of the auxiliary positioning unit 40 to shorten, so that the positioning switch 403 avoids the pipe fitting, and at the same time starts the pipe fitting pushing unit 20 to perform a new round of pipe fitting pushing action. After the cut pipe fitting is separated from the pipe fitting to be cut, the adjusting telescopic cylinder three 401 elongates, and the positioning switch 403 re - positions the pipe fitting to achieve continuous positioning and cutting.

[0051] In summary, through the coordinated work of the central bearing unit 10, the pipe fitting pushing unit 20, and the auxiliary positioning unit 40, the present invention realizes the accurate positioning and stable cutting of the pipe fitting cutting position, improves the cutting accuracy and efficiency, and at the same time supports multi - angle cutting to meet the production requirements of different vehicle frames.

[0052] The technical features of the above - described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above - described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0053] The above - described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
