Description

Technical Field

[0001] The invention relates to the field of laser cutting equipment, in particular to a semi-automatic loading and unloading mechanism and an ultra-long, heavy-duty, high-performance laser cutting machine. Background Art

[0002] Defects and shortcomings of existing laser tube cutting machines:

[0003] 1. Currently, the laser tube cutting machines on the market support cutting of smaller tube specifications, with the maximum tube specification only supporting 550mm. Large and extra-large tube cutting machines cannot meet the cutting requirements.

[0004] 2. At present, all domestic chucks are cylinder-driven jaws, so the clamping force of the chuck is limited. The jaws can also achieve automatic centering for small-diameter and light-weight pipes. However, for long and extra-long heavy pipes, the jaws cannot clamp the pipes that deviate from the center of the chuck to the position where the center of the pipe is concentric with the center of the chuck, that is, the automatic centering function cannot be completed, so the chuck only plays the role of clamping and rotating. And it is necessary to ensure that the center of the pipe is concentric with the center of the chuck, and there is no good structure, which leads to poor cutting accuracy.

[0005] 3. Almost all the feeding structures on the market are chains with ear plates added to push the structure. This structure cannot fix the round tubes when loading and unloading them. During the transportation process, the round tubes are prone to overshoot, causing a collision.

[0006] 4. Due to the large size and heavy weight of the pipes, the traditional rolling and dropping material feeding structure is dangerous and noisy.

[0007] Therefore, it is necessary to design a device for accurately feeding long and extra-long heavy pipes to solve the problem that accurate feeding (the center of the pipe is concentric with the center of the chuck) cannot be achieved. Summary of the invention

[0017] The self-positioning member comprises a positioning roller 1 arranged in parallel with the large inclined surface and a positioning roller 2 arranged in parallel with the small inclined surface.

[0018] In the present application, a plurality of guide sleeves are installed on the movable platform, and a polished rod that is slidably matched with the guide sleeves is provided on the lifting frame;

[0019] The servo assembly includes a servo motor and a screw lifter, and the output end of the servo motor drives the lifting frame to move vertically through the screw lifter;

[0020] The conveying assembly comprises a driving motor, which is mounted on a moving platform, and a conveying gear is mounted on the output end, a rack is mounted on the conveying frame, and the conveying gear and the rack are meshed.

[0021] In the present application scheme, a moving component is installed on the lifting frame, and the moving component includes a moving plate that slides on the top of the lifting frame, and the movement direction of the moving plate is parallel to the layout direction of the conveying parts. A driver 1 is installed on the top of the lifting frame, and a screw is installed on the output end of the driver 1. The screw is rotatably installed on the lifting frame, and a moving block is matched and installed on the screw. The moving block is installed on the moving plate, and the moving block slides relative to the lifting frame. An anti-vibration component is installed on the moving plate, and it is used to suspend and support the pipe.

[0022] In the present application, the anti-vibration component includes a second driver installed on a movable plate, an adjusting screw is installed at the output end of the second driver, a movable seat is connected to the adjusting screw through a thread, the movable seat slides relative to the movable plate and the sliding direction is parallel to the movement direction of the movable plate, the top of the movable seat is rotatably connected to a rod, the end of the rod is rotatably installed with a suspension support block, and the end of the suspension support block away from the rod is hingedly installed on the movable plate.

[0023] In the present application, the suspension support block is an arc-shaped structure and an electromagnetic structure is installed on the top. After the electromagnetic structure is energized, it is used to support the pipe until the pipe is attached to the ground on the conveying member.

[0024] In the present application, limit seats are provided at both ends of the conveying frame, and the limit seats include a fixed frame, which is an L-shaped plate. An adjusting rod is installed on the top of the fixed frame, one end of the adjusting rod is fixed with a stopper, and the other end passes through the top of the fixed frame and is installed with an adjusting nut. A spring body is mounted on the outer side of the adjusting rod, and the spring body is arranged between the fixed frame and the stopper.

[0025] A method for using a semi-automatic loading and unloading mechanism, comprising:

[0026] Step 1: Pipe placement

[0027] The large pipes are placed in the storage body of the storage rack through the lifting equipment. The large pipes are rolled down through the large slope to the junction with the small slope, and the position is limited by the small slope and the large slope;

[0028] Step 2: Pipe lifting

[0029] The driving motor drives the conveying gear to rotate and moves the mobile platform to the bottom of the pipe. At this time, the positioning roller 1 and the large slope are in corresponding and parallel positions, and the positioning roller 2 and the small slope are in corresponding and parallel positions. The piston rod of the lifting cylinder extends outward to drive the installation platform to move upward to the set height, that is, when the positioning roller 1 and the positioning roller 2 are in contact with the outer wall of the pipe, the conveying part is in contact with the outer wall of the pipe;

[0030] The servo motor moves the lifting frame upward through the screw lifter until the pipe is completely separated from the containing body and reaches the set height. The set height is that the axis of the pipe and the axis of the chuck are in the same horizontal plane.

[0031] Step 3: Horizontal transportation of pipes

[0032] The driving motor drives the conveying gear to rotate, and the mobile platform moves along the rack layout direction toward the chuck until the axis of the pipe coincides with the axis of the chuck;

[0033] Step 4: Fix the pipe

[0034] The chuck clamps the end of the pipe, the piston rod of the lifting cylinder drives the self-positioning part to reset, and the pipe is axially transported to the cutting equipment to the rated length. During the axial transportation process, the lifting frame that interferes with the chuck is automatically reset by the servo motor and the screw lifter.

[0035] In the present application, in step 2, before the servo motor moves the lifting frame upward via the screw lifter, driver 1 drives the lead screw to rotate and move the movable plate until the shockproof assembly is directly below the pipe. After the electromagnetic structure is energized, it forms a repulsive force on the pipe. Driver 2 drives the movable seat to adjust the suspension support block to a position that matches the suspension support position of the pipe by adjusting the adjustment screw. When the lifting frame moves up to the set position, the suspension support block suspends and supports the pipe on the conveying member and there is no force between the outer wall of the pipe and the conveying member.

[0036] An ultra-heavy laser tube cutting machine comprises a cutting device and a semi-automatic loading and unloading mechanism.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. The present invention installs a lifting frame on a mobile platform, and uses the self-positioning parts on the lifting frame to match the structure of the holding frame to achieve structural matching. After moving to the bottom of the holding frame, the self-positioning parts are used to realize self-positioning of the pipe when it is lifted upward, and the position is consistent with the horizontal position on the holding frame. It only needs to control the horizontal conveying distance to control the horizontal position coincidence of the pipe and the chuck. At the same time, the horizontal conveying adopts a gear rack structure to achieve precise fixed-point conveying. By controlling the lifting height, it can ensure that the chuck and the pipe are concentric, and then the conveying accuracy can be precisely controlled to complete precise conveying.

[0039] 2. The gravity of the pipe of the present invention mainly acts on the conveying member, and the self-positioning member is only used to limit the horizontal position of the pipe during the conveying process to prevent relative displacement on the horizontal plane, thereby accurately controlling the horizontal accuracy. During the pipe cutting process, the pipe is always held up by the conveying member, so the middle part of the pipe will not be deformed under the action of gravity, and there will be no problem with the accuracy of the cutting surface.

[0040] 3. The present invention has a movable plate and a suspended support structure on the movable plate at the top of the lifting frame. The position of the movable plate can be moved along the direction parallel to the layout of the conveyor to adjust the position of the movable plate. The suspended support structure on the movable plate can support the middle area of ​​the pipe under the action of power, which can reduce the friction resistance of the pipe during the rotation cutting process, thereby eliminating the noise and vibration of the pipe in this process and ensuring the quality of the cutting surface. Once vibration occurs, it will seriously affect the structural stability of the chuck cantilever, the noise generated will increase the rotation resistance, and jamming will occur in severe cases. At the same time, the degree of damage and wear of the outer wall of the pipe will increase. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0052] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0053] Example 1

[0054] like Figures 1 to 6 As shown, a semi-automatic loading and unloading mechanism comprises:

[0055] A holding rack 10, a holding body 11 is disposed on the top of the holding rack 10, and the holding body 11 is used to hold the pipes;

[0056] The conveying frame 20 is independently arranged on one side of the containing frame 10, and a conveying component is installed on the conveying frame 20.

[0057] A movable platform 30, wherein the movable platform 30 is mounted on the conveying assembly and moves toward the chuck under the action of the conveying assembly;

[0058] A self-positioning assembly, which includes a positioning lifting frame 40, a self-positioning member 41 is installed on the top of the positioning lifting frame 40, and the self-positioning member 41 is used to limit the left and right movement of the pipe. A lifting cylinder 42 is installed at the bottom of the positioning lifting frame 40, and a mounting platform 43 is installed at the bottom of the lifting cylinder 42;

[0059] A lifting assembly, the lifting assembly includes a servo assembly 50, the servo assembly 50 is installed on the moving platform 30, a lifting frame 52 is installed on the top of the servo assembly 50, a conveying member 51 is installed on the top of the lifting frame 52, and the mounting platform 43 and the lifting frame 52 are connected and fixed;

[0060] When the lifting cylinder 42 lifts up the pipe from the positioning member 41 , the bottom of the pipe is located on the conveying member 51 .

[0061] There are multiple containing bodies 11 arranged along the feeding direction, and the top of each containing body 11 is provided with a large inclined surface 111 arranged obliquely downward and a small inclined surface 112 arranged obliquely upward, and the pipe is contained in the area surrounded by the large inclined surface 111 and the small inclined surface 112;

[0062] like Figure 2 As shown, the self-positioning member 41 includes a positioning roller 1 411 arranged parallel to the large inclined surface 111 and a positioning roller 2 412 arranged parallel to the small inclined surface 112 .

[0063] The movable platform 30 is provided with a plurality of guide sleeves 31, and the lifting frame 52 is provided with a guide sleeve 32 which is slidably matched with the guide sleeve 31;

[0064] The servo assembly 50 includes a servo motor and a screw lifter, and the output end of the servo motor drives the lifting frame 52 to move vertically through the screw lifter;

[0065] The conveying assembly includes a driving motor 21 , which is mounted on a moving platform 30 , and a conveying gear 22 is mounted on the output end. A rack 23 is mounted on the conveying frame 20 , and the conveying gear 22 and the rack 23 are meshed.

[0066] Both ends of the conveying frame 20 are provided with limit seats, which include a fixed frame 201, which is an L-shaped plate, and an adjusting rod 202 is installed on the top of the fixed frame 201. One end of the adjusting rod 202 is fixed with a stopper 203, and the other end passes through the top of the fixed frame 201 and is installed with an adjusting nut 204. The outer side of the adjusting rod 202 is sleeved with a spring body 205, and the spring body 205 is arranged between the fixed frame and the stopper 203. The arrangement of the spring body 205 can reduce the buffering operation of the conveying terminal mobile platform 30 to prevent the problem of movement.

[0067] During implementation, the pipe is placed in the containing body 11, and the axial position of the pipe is calculated by setting the specifications of the pipe by the system. The driving motor drives the conveying gear 22 to move along the rack 23 to the bottom of the pipe. At this time, the positioning roller 1 411 and the positioning roller 2 412 are respectively parallel to the large inclined surface 111 and the small inclined surface 112. Then the lifting cylinder 42 moves the positioning lifting frame 40 up to the set height position, and the servo assembly 50 lifts the lifting frame 52 to lift the pipe until the center of the pipe is at the same height as the center of the chuck. The driving motor 21 drives the conveying gear 22 to move the positioning lifting frame 40 to the set height position. The rack 23 transports the pipe to the position where the center of the pipe and the center of the chuck coincide. The chuck moves and clamps one end of the pipe and transports it forward a certain distance, so that the chuck close to the cutting device also clamps the outer wall of the pipe. The chuck transports the pipe to the cutting device for cutting. During the transportation process, the lifting assembly and self-positioning assembly that interfere with the pipe are automatically reset. Before cutting, the lifting cylinder 42 needs to move the self-positioning part 41 downward to separate it from the pipe and reset it to its initial position relative to the mounting platform 43 to avoid jamming caused by large rotational resistance during rotary pipe cutting.

[0068] Example 2

[0069] Based on the above embodiment, the following improvements are made: Figure 7 , 8As shown, a moving component is installed on the lifting frame 52, and the moving component includes a moving plate 521 that is slidably fitted on the top of the lifting frame 52, and the movement direction of the moving plate 521 is parallel to the layout direction of the conveying member 51. A driver 5201 is installed on the top of the lifting frame 52, and a screw 522 is installed on the output end of the driver 5201. The screw 522 is rotatably installed on the lifting frame 52, and a moving block 523 is matched and installed on the screw 522. The moving block 523 is installed on the moving plate 521, and the moving block 523 is slidably fitted relative to the lifting frame 52. An anti-vibration component is installed on the moving plate 521, and is used to suspend and support the pipe.

[0070] The anti-vibration component includes a second driver 524 installed on a movable plate 521, an adjusting screw 525 is installed at the output end of the second driver 524, and two movable seats 526 with opposite movement directions are threadedly connected to the adjusting screw 525, the movable seats 526 are slidably matched relative to the movable plate 521 and the sliding direction is parallel to the movement direction of the movable plate 521, the top of the movable seat 526 is rotatably connected to a rod 527, and a suspension support block 528 is rotatably installed at the end of the rod 527, and the end of the suspension support block 528 away from the rod 527 is hingedly installed on the movable plate 521.

[0071] The suspension support block 528 is an arc-shaped structure with an electromagnetic structure 529 installed on the top. After being energized, the electromagnetic structure 529 is used to support the pipe until the bottom surface of the outer wall of the pipe contacts the conveying member 51.

[0072] Before the lifting frame 52 lifts the pipe upward, the electromagnetic structure 529 is energized, and the electromagnetic structure 529 generates a repulsive force on the pipe. When the lifting frame 52 lifts the pipe away from the containing body 11, the electromagnetic structure 529 overcomes the gravity of the pipe so that the pipe contacts the conveying member 51, avoiding the friction resistance with the conveying member 51 and jamming during the rotation cutting process. The effect is more significant especially for thin-walled pipes, because if only the conveying member 51 is used, stress concentration is likely to occur at the bottom of the outer wall, resulting in deformation of the bottom of the pipe. In addition, the pipe rotation cutting operation will inevitably seriously affect the cutting quality of the pipe. Of course, for pipes with ordinary wall thickness, it can play a role in reducing friction, reducing rotation resistance, avoiding many problems such as wear and tear of the outer wall of the pipe, noise, jamming, and affecting the stability of the chuck.

[0073] A method for using a semi-automatic loading and unloading mechanism, the steps are as follows:

[0074] Step 1: Pipe placement

[0075] The large pipe is placed in the containing body 11 of the containing rack 10 by means of a lifting device. The large pipe rolls down through the large inclined surface 111 to the junction with the small inclined surface 112, and the position of the large pipe is limited by the small inclined surface 112 and the large inclined surface 111;

[0076] Step 2: Pipe lifting

[0077] The driving motor 21 drives the conveying gear 22 to rotate, and moves the movable platform 30 to the bottom of the pipe. At this time, the positioning roller 1 411 and the large inclined surface 111 correspond to each other in vertical position and are parallel to each other, and the positioning roller 2 412 and the small inclined surface 112 correspond to each other in vertical position and are parallel to each other. The piston rod of the lifting cylinder 42 extends outward to drive the mounting platform 43 to move upward to the set height, that is, when the positioning roller 1 411 and the positioning roller 2 412 contact the outer wall of the pipe, the conveying member 51 contacts the outer wall of the pipe.

[0078] The servo motor moves the lifting frame 52 upward through the screw lifter until the pipe is completely separated from the containing body 11 and reaches the set height. The set height is that the axis of the pipe and the axis of the chuck are in the same horizontal plane.

[0079] Step 3: Horizontal transportation of pipes

[0080] The driving motor 21 drives the conveying gear 22 to rotate, and the moving platform 30 moves toward the chuck along the arrangement direction of the rack 23 until the axis of the pipe coincides with the axis of the chuck;

[0081] Step 4: Fix the pipe

[0082] The chuck clamps the end of the pipe, the piston rod of the lifting cylinder 42 drives the self-positioning member 41 to reset, and axially transports the pipe to the cutting equipment to the rated length (cutting length). During the axial transportation process, the lifting frame 52 that interferes with the chuck is automatically reset under the action of the servo motor and the screw lifter.

[0083] In step 2, before the servo motor moves the lifting frame 52 upward via the screw lifter, driver 1 5201 drives the lead screw 522 to rotate and move the movable plate 521 until the shockproof component is directly below the pipe. After the electromagnetic structure 529 is energized, it forms a repulsive force on the pipe. Driver 2 524 drives the movable seat 526 to adjust the suspension support block 528 to a position suitable for suspending and supporting the pipe by adjusting the adjustment screw 525. When the lifting frame 52 moves up to the set position, the suspension support block 528 suspends and supports the pipe on the conveying member 51 and there is no force between the outer wall of the pipe and the conveying member 51.

[0084] like Fig. 9 As shown, an ultra-heavy laser tube cutting machine includes a cutting device and a semi-automatic loading and unloading mechanism.

[0085] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The replacement may be a replacement of a part of the structure, device, method step, or a complete technical solution. Any equivalent replacement or change according to the technical solution and the inventive concept of the present invention shall be covered within the protection scope of the present invention.

A method for using a semi-automatic loading and unloading mechanism, comprising the loading and unloading mechanism according to claim 6, characterized in that: Here are the steps: Step 1: Pipe placement The large pipe is placed in the containing body (11) of the containing rack (10) by means of a lifting device, and the large pipe is rolled down through the large inclined surface (111) to the junction with the small inclined surface (112), and the position of the large pipe is defined by the small inclined surface (112) and the large inclined surface (111); Step 2: Pipe lifting The driving motor (21) drives the conveying gear (22) to rotate, and moves the movable platform (30) to the bottom of the pipe. At this time, the positioning roller 1 (411) and the large inclined surface (111) correspond to each other in upper and lower positions and are parallel to each other, and the positioning roller 2 (412) and the small inclined surface (112) correspond to each other in upper and lower positions and are parallel to each other. The piston rod of the lifting cylinder (42) extends outward to drive the mounting platform (43) to move upward to a set height, that is, when the positioning roller 1 (411) and the positioning roller 2 (412) contact the outer wall of the pipe, the conveying member (51) contacts the outer wall of the pipe. The servo motor moves the lifting frame (52) upward via the screw lifter until the pipe is completely separated from the containing body (11) and reaches a set height, wherein the set height is such that the axis of the pipe and the axis of the chuck are in the same horizontal plane; Step 3: Horizontal transportation of pipes The driving motor (21) drives the conveying gear (22) to rotate, and the moving platform (30) moves along the arrangement direction of the rack (23) toward the chuck until the axis of the pipe coincides with the axis of the chuck; Step 4: Fix the pipe The chuck clamps the end of the pipe, the piston rod of the lifting cylinder (42) drives the self-positioning member (41) to reset, and the pipe is axially conveyed to the cutting device to a rated length. During the axial conveying process, the lifting frame (52) that interferes with the chuck is automatically reset under the action of the servo motor and the screw lifter.

9. The method for using a semi-automatic loading and unloading mechanism according to claim 8, characterized in that: In step 2, before the servo motor moves the lifting frame (52) upward via the screw lifter, driver 1 (5201) drives the lead screw (522) to rotate and move the movable plate (521) to the point where the shockproof assembly is directly below the pipe. After the electromagnetic structure (529) is energized, it forms a repulsive force on the pipe. Driver 2 (524) drives the movable seat (526) to adjust the suspension support block (528) to a position that matches the suspension support position of the pipe by adjusting the adjustment lead screw (525). When the lifting frame (52) moves upward to the set position, the suspension support block (528) suspends and supports the pipe on the conveying member (51) and there is no force between the outer wall of the pipe and the conveying member (51).

10. An ultra-heavy laser tube cutting machine, characterized in that: The invention comprises a cutting device and a semi-automatic loading and unloading mechanism as claimed in any one of claims 1 to 7.
