DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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 intended to limit the present invention.

[0035] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0036] like Figure 1 , Figure 3 and Figure 6 As shown, in one embodiment, a highly efficient cutting device for a seamless stainless steel pipe is provided, the device comprising:

[0037] The main frame 1 includes a mounting platform 101 disposed on the main frame 1, and a curved plate 102 is fixedly mounted on the surface of the mounting platform 101;

[0038] Adjustment mechanism 2: comprises a sliding cylinder 201 mounted on the mounting platform 101, a moving frame 202 penetrates the interior of the sliding cylinder 201, and the sliding cylinder 201 is slidably connected to the moving frame 202, a connecting rod 203 is fixedly mounted on the surface of the moving frame 202, a sliding ball 204 is rotatably connected to the surface of the connecting rod 203, a laser cutter 205 is fixedly mounted on one end of the moving frame 202 away from the connecting rod 203, and the moving frame 202 and the sliding cylinder 201 are connected via a return spring 206;

[0039] Pitch-changing mechanism 3: used to adjust the distance between the adjusting mechanism 2 and the stainless steel seamless pipe at different angles;

[0040] Reciprocating mechanism 4: used to adjust the movement speed of the adjusting mechanism 2;

[0041] Deflection mechanism 7: used to drive the adjustment mechanism 2 to revolve;

[0042] Conveying mechanism 9: used for positioning and conveying the stainless steel seamless pipe.

[0043] In practical application, when the stainless steel seamless steel pipe is cut, Figure 1 As shown, at this time, the stainless steel seamless steel pipe is driven to move to the bottom of the adjusting mechanism 2 under the action of the conveying mechanism 9, and the conveying mechanism 9 is fed back to the conveying mechanism 9 through the induction photoelectric feedback. At this time, the conveying mechanism 9 stops running. At this time, the adjusting mechanism 2 is driven to revolve under the action of the deflection mechanism 7. After the adjusting mechanism 2 rotates to the corresponding angle, the deflection mechanism 7 stops rotating. Figure 6 As shown, during the rotation of the deflection mechanism 7, the sliding ball 204 moves toward the position close to the steel pipe under the action of the pitch changing mechanism 3. The movement of the sliding ball 204 drives the laser cutter 205 to move toward the position close to the steel pipe through the connecting rod 203 and the moving frame 202, thereby automatically adjusting the distance from the steel pipe according to the cutting angle of the steel pipe, and realizing the function of fully cutting the steel pipe. At the same time, when the laser cutter 205 rotates to the corresponding angle, as shown in FIG. Figure 3 As shown, at this time, under the action of the reciprocating mechanism 4, the laser cutter 205 is driven by the sliding cylinder 201 to move horizontally. At this time, under the action of the variable pitch mechanism 3, the laser cutter 205 increases with the increase of the rotation angle. The speed of the horizontal movement of the laser cutter 205 when cutting the steel pipe decreases accordingly, thereby automatically reducing the cutting speed as the cutting angle increases, thereby achieving the purpose of fully cutting the steel pipe.

[0044] like Figure 6 As shown, as a preferred embodiment of the present invention, the pitch changing mechanism 3 includes a fixed arc block 301 fixedly mounted on the arc plate 102 , and the fixed arc block 301 is in contact with the sliding ball 204 .

[0045] In practical application of the embodiment of the present invention, when the adjustment mechanism 2 revolves under the action of the deflection mechanism 7, as shown in FIG. Figure 6 As shown, at this time, the sliding ball 204 slides along the trajectory of the fixed arc block 301. Through the arc setting of the pitch-changing mechanism 3, the sliding ball 204 drives the laser cutter 205 to move toward a position close to the steel pipe. At the same time, as the revolution angle of the adjustment mechanism 2 increases, the arc slope of the pitch-changing mechanism 3 becomes larger, and the laser cutter 205 is closer and closer to the steel pipe, thereby achieving the function of automatically adjusting the cutting distance of the laser cutter 205 and realizing full cutting.

[0046] like Figure 3 and Figure 8 As shown, as another preferred embodiment of the present invention, the reciprocating mechanism 4 includes a reciprocating wheel 401 installed on the mounting platform 101, and an inclined groove 402 is opened inside the reciprocating wheel 401. The inclined groove 402 is in contact with the slide ball 403, and the slide ball 403 is rotatably connected to the reciprocating rod 404. The end of the reciprocating rod 404 away from the slide ball 403 is fixedly connected to the sliding cylinder 201.

[0047] In practical application of the embodiment of the present invention, after the angle adjustment of the laser cutter 205 is completed, Figure 3 and Figure 8 As shown, at this time, the reciprocating wheel 401 starts to rotate, and the rotation of the reciprocating wheel 401 drives the slide ball 403 to move laterally through the trajectory of the inclined groove 402. Each time the reciprocating wheel 401 is cut, it rotates half a circle, thereby driving the reciprocating rod 404 to move laterally. The slide ball 403 is set to convert the sliding friction between the reciprocating rod 404 and the inclined groove 402 into rolling friction, thereby reducing friction and increasing the service life of the device. The lateral movement of the reciprocating rod 404 drives the sliding cylinder 201 to move laterally, thereby driving the laser cutter 205 to move laterally. At the same time, as the angle of the laser cutter 205 increases, the rotation speed of the reciprocating wheel 401 decreases accordingly, thereby achieving full cutting of the steel pipe.

[0048] like Figure 3 , Figure 4 , Figure 6 and Fig.10As shown, as another preferred embodiment of the present invention, the device also includes a feedback mechanism 5, the feedback mechanism 5 includes a linkage rod 501 slidably connected to the sliding cylinder 201, the surface of the linkage rod 501 is fixedly connected to a transmission frame 502, the end of the transmission frame 502 away from the linkage rod 501 is fixedly installed with a moving slider 503, the surface of the moving slider 503 is rotatably connected to a swing rod 504, the end of the swing rod 504 away from the moving slider 503 is rotatably connected to a thrust slider 505, the thrust slider 505 is fixedly installed on the surface of the inclined groove block 506, the interior of the inclined groove block 506 is penetrated by a guide rod 507, and the inclined groove block 506 is slidably connected to the guide rod 507, the surface of the inclined groove block 506 is rotatably connected to a feedback bevel gear 508, and the feedback bevel gear 508 is meshed with the transmission mechanism 6.

[0049] In practical application of the embodiment of the present invention, when the laser cutter 205 moves toward the steel pipe position under the action of the pitch changing mechanism 3, as shown in FIG. Figure 6 As shown, at this time, the downward movement of the moving frame 202 drives the linkage rod 501 to move downward, as shown in FIG. Fig.10 As shown, from Fig.10 From the front view direction, the downward movement of the linkage rod 501 drives the movable slider 503 to move downward through the transmission frame 502. Figure 4 As shown, the swing rod 504 is driven to swing, and the swing of the swing rod 504 drives the inclined groove round block 506 to slide along the guide rod 507 through the thrust slider 505, and then drives the feedback bevel gear 508 to slide along the guide rod 507, thereby changing the rotation speed of the transmission mechanism 6, as shown in FIG. Figure 3 As shown, when the rotation angle of the laser cutter 205 increases, the feedback bevel gear 508 is driven to slide along the guide rod 507. The sliding distance increases, thereby increasing the rotation radius of the output end of the transmission mechanism 6, so that the rotation speed of the output end of the transmission mechanism 6 decreases, thereby driving the rotation speed of the reciprocating mechanism 4 to decrease. As the thickness of the cutting tube increases, the cutting speed is automatically adjusted to achieve the purpose of sufficient cutting. At the same time, the rotation speed is automatically adjusted by utilizing the different rotation radii of the bevel gear.

[0050] like Figure 4 As shown, as another preferred embodiment of the present invention, the device also includes a transmission mechanism 6, the transmission mechanism 6 includes a transmission motor 601 fixedly mounted on the bevel groove block 506, a transmission bevel gear 602 is fixedly mounted on the output end of the transmission motor 601, the transmission bevel gear 602 is meshed with a driven bevel gear disc 603, the driven bevel gear disc 603 is fixedly mounted on the surface of the feedback bevel gear 508, the feedback bevel gear 508 is meshed with a trapezoidal bevel gear cylinder 604, and the inner wall of the trapezoidal bevel gear cylinder 604 is fixedly connected to the reciprocating wheel 401.

[0051] In practical application, the embodiment of the present invention is as follows: Figure 4As shown, when the laser cutter 205 completes the angle adjustment, the transmission motor 601 starts to move. The operation of the transmission motor 601 drives the feedback bevel gear 508 to rotate through the gear meshing action, and then drives the trapezoidal bevel gear cylinder 604 to rotate. The rotation of the trapezoidal bevel gear cylinder 604 drives the laser cutter 205 to move horizontally through the reciprocating wheel 401, thereby realizing the function of automatically controlling the laser cutter 205 to perform horizontal movement cutting.

[0052] like Figure 3 As shown, as another preferred embodiment of the present invention, the device further includes a deflection mechanism 7, the deflection mechanism 7 includes a deflection motor 701 fixedly mounted on the mounting platform 101, a main turntable 702 is fixedly mounted on the output end of the deflection motor 701, the main turntable 702 is connected to the auxiliary turntable 704 through a support shaft 703, a rotating support block 705 is fixedly mounted on the surface of the auxiliary turntable 704, the rotating support block 705 is slidably connected to the surface of the mounting platform 101, and an induction contact is fixedly mounted on the surface of the rotating support block 705 706, the surface of the auxiliary turntable 704 is rotatably connected to the reciprocating wheel 401, the interior of the auxiliary turntable 704 is penetrated by a reciprocating rod 404, and the reciprocating rod 404 is slidably connected to the auxiliary turntable 704, the surface of the auxiliary turntable 704 is slidably connected to a movable slider 503, the surface of the auxiliary turntable 704 is fixedly installed with a guide rod 507, the auxiliary turntable 704 is connected to the main turntable 702 through a connecting slider 707, the connecting slider 707 is slidably connected to the sliding cylinder 201, and the induction contact 706 touches the angle mechanism 8 to feedback the signal.

[0053] In actual application, when cutting a steel pipe, the employee adjusts the angle mechanism 8 to set the cutting angle. After the adjustment is completed, the deflection motor 701 starts to move. The operation of the deflection motor 701 drives the auxiliary turntable 704 to rotate through the main turntable 702 and the support shaft 703, and then drives the laser cutter 205 to deflect through the connecting slider 707. At this time, when the sensing contact 706 contacts the angle mechanism 8, the signal is fed back to the deflection motor 701, and the deflection motor 701 stops running, thereby realizing the function of automatically adjusting the cutting angle.

[0054] like Figure 3 As shown, as another preferred embodiment of the present invention, the device also includes an angle mechanism 8, which includes an angle dial 801 that passes through the mounting table 101, and the angle dial 801 is rotatably connected to the mounting table 101, the angle dial 801 passes through the interior of the scale plate 804, and is rotatably connected to the scale plate 804, the scale plate 804 is fixedly mounted on the surface of the mounting table 101, a reference dial 802 is fixedly mounted on the surface of the angle dial 801, a feedback contact 803 is fixedly mounted on the surface of the reference dial 802, and the feedback contact 803 is in contact with the induction contact 706.

When the angle dial 801 rotates to the required cutting angle on the scale plate 804, the angle dial 801 is fixed. When the sensing contact 706 rotates and touches the feedback contact 803, a feedback signal is given to the deflection motor 701, thereby realizing the function of automatically and accurately adjusting the cutting angle.

[0057] In practical application, the embodiment of the present invention is as follows: Figure 1 As shown, when cutting the steel pipe, the steel pipe is placed on the supporting triangle 904 through an external clamping device. The setting of the supporting triangle 904 increases the stability of the steel pipe positioning. At this time, the operation of the conveying motor 901 drives the conveying wheel 902 to rotate, and then drives the conveying chain 903 to rotate, and the steel pipe is conveyed to the cutting position.
