Description

[0002] Laser cutting has the characteristics of high flexibility, fast cutting speed, high production efficiency and short product production cycle, so it is widely used in the manufacturing industry, such as using laser to cut pipes or profiles.

[0003] After the existing pipe fittings are cut by the laser cutting head on the pipe cutting machine, a material receiving mechanism is generally provided to assist in unloading. The existing material receiving mechanism generally drives the material receiving component provided on the output end of the material receiving cylinder to rise by lifting the material receiving cylinder, and unloads the pipe fittings on the material receiving component through the material storage mechanism when the material receiving component descends.

DETAILED DESCRIPTION

[0027] The present invention provides a material receiving support mechanism. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. 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 scope of protection of the present invention.

[0028] See also Figure 1 , Figure 2 and Figure 3 The present invention provides a material receiving support mechanism, including a material receiving base frame 1, a fixed plate 2 arranged on the material receiving base frame 1, a first-stage movable plate 3 arranged on the fixed plate 2 and capable of being raised and lowered, a second-stage movable plate 4 arranged on the first-stage movable plate 3 and capable of being raised and lowered, a first-stage material receiving component 5 for driving the first-stage movable plate 3 to be raised and lowered, and a second-stage material receiving component 6 for driving the second-stage movable plate 4 to be raised and lowered following the first-stage movable plate 3 to be raised and lowered, a material receiving plate 7 is hingedly connected to the top of the second-stage movable plate 4, and a material receiving drive component 8 for driving the material receiving plate 7 to be horizontally or tilted downward is arranged on the second-stage movable plate 4.

[0029] In actual application, the material receiving support mechanism is located behind the rear section of the pipe cutting machine (that is, the pipe cutting machine is located in front of the material receiving support mechanism), the front section of the pipe cutting machine is used for feeding the pipe fittings, and the middle section of the pipe cutting machine is used for cutting the pipe fittings. The two ends and the middle part of the pipe fittings are fixed by a chuck arranged on the pipe cutting machine, and the chuck can reciprocate along the length direction of the pipe cutting machine.

[0030] The front side of the material receiving frame 1 is connected to the rear side of the pipe cutting machine to fix the material receiving frame 1. Figure 3 and Figure 5 When the pipe is cut, under the action of the first-stage receiving component 5, the first-stage movable plate 3 is driven to rise. At the same time, under the action of the second-stage receiving component 6, the second-stage movable plate 4 rises along with the rise of the first-stage movable plate 3, so that the second-stage movable plate 4 realizes a two-stage rising support stroke. When the second-stage movable plate 4 rises, the receiving drive component 8 and the receiving plate 7 arranged thereon are driven to rise synchronously. At this time, under the action of the receiving drive component 8, the receiving plate 7 is in a horizontal state, and the receiving plate 7 abuts against the bottom end of the pipe being cut. When the pipes to be cut are rectangular pipes, square pipes, H-shaped steel, channel steel, angle iron and other profiles, the distance from the lowest point of the profile to the ground changes at any time due to the rotation of the profile driven by the chuck. Therefore, under the joint action of the first-stage receiving assembly 5 and the second-stage receiving assembly 6, the first-stage movable plate 3 and the second-stage movable plate 4 follow the change in the height of the pipe from the ground and change their lifting height accordingly, so that the receiving plate 7 can support the pipes accordingly, which can effectively prevent large and heavy pipes from shaking during rotation or movement, thereby reducing the cutting accuracy. Please refer to Figure 1 and Figure 7 After the cutting is completed, the chuck releases the clamping of the pipe fitting, and the pipe fitting is supported on the receiving plate 7. While the first-stage receiving assembly 5 drives the first-stage movable plate 3 to descend, the second-stage receiving assembly 6 drives the second-stage movable plate 4 to descend until the heights of the fixed plate 2, the first-stage movable plate 3 and the second-stage movable plate 4 are basically the same; then, under the action of the receiving drive assembly 8, the rear end of the receiving plate 7 is tilted downward, so that the round tube rolls to the unloading rack located behind the receiving support mechanism or the profile slides to the unloading rack located behind the receiving support mechanism under the guidance of the inclined receiving plate 7.

[0031] The material receiving support mechanism is provided with a material receiving base frame 1 for installing a fixed plate 2, a first-stage material receiving component 5 for driving a first-stage movable plate 3 to rise or fall, a second-stage material receiving component 6 for driving a second-stage movable plate 4 to rise when it rises or fall when it falls following the first-stage movable plate 3, and a material receiving drive component 8 for making the material receiving plate 7 horizontal or inclined, so that the material receiving support mechanism has the function of supporting the pipe fittings up and down, and realizes the support stroke with the minimum compression ratio of the two-stage rise or fall, can realize a larger moving stroke, adapts to the material receiving height requirements of the pipe cutting machine, and is conducive to the rational use of space.

[0032] See also Figure 3 , Figure 5 and Figure 6 Further, the two-stage material receiving assembly 6 includes a first material receiving positioning block 61 arranged on the front side of the fixed plate 2, a second material receiving positioning block 62 arranged on the front side of the second-stage movable plate 4, two material receiving bearing seats 63 arranged on the upper side walls of the first-stage movable plate 3, a rotating shaft 64 rotatably arranged between the two material receiving bearing seats 63, a material receiving sprocket 65 arranged on both ends of the rotating shaft 64, and a material receiving chain 66 connected to the first material receiving positioning block 61 and the second material receiving positioning block 62 at both ends, and the middle position of the material receiving chain 66 is meshed with the corresponding material receiving sprocket 65 for transmission. Two material receiving sprockets 65 and two material receiving chains 66 are arranged to ensure force balance, and one rotating shaft 64 drives the two material receiving sprockets 65 to rotate coaxially.

[0033] Specifically, the lower part of the second-stage movable plate 4 is provided with an N-shaped groove for avoiding the first-stage receiving component 5. Figure 3 , Figure 5 and Figure 6 The two ends of the material receiving chain 66 are respectively fixed on the first material receiving positioning block 61 and the second material receiving positioning block 62, that is, the two ends of the material receiving chain 66 are equivalent to being connected to the front side of the fixed plate 2 and the second movable plate 4 respectively. When the first material receiving component 5 rotates forward to drive the first movable plate 3 and the material receiving bearing seat 63, rotating shaft 64, and material receiving sprocket 65 arranged on the first movable plate 3 to rise synchronously, under the driving action of the material receiving sprocket 65, the material receiving chain 66 with one end connected to the front side of the fixed plate 2 is subjected to force to pull the second movable plate 4 to rise synchronously, realizing the supporting stroke of the two-stage rise. Please refer to Figure 7 On the contrary, when the first section receiving assembly 5 rotates in the opposite direction to drive the first section movable plate 3 to descend, the receiving sprocket wheel 65 is always engaged with the receiving chain 66, and the second section movable plate 4 is synchronously descended under the gravity of the second section movable plate 4 and the traction of the receiving chain 66 until the heights of the second section movable plate 4, the first section movable plate 3 and the highest position of the fixed plate 2 are basically the same. The above structure is simple and ingeniously designed. By adopting the receiving chain 66 and the receiving sprocket wheel 65, the second section movable plate 4 can be pulled up or down following the first section movable plate 3, the manufacturing cost is low, and the effect of achieving a two-stage lifting stroke is remarkable.

[0034] See also Figure 5Furthermore, a tension adjustment block 67 is provided on the front side of the fixed plate 2, and the tension adjustment block 67 is arranged above the first material receiving and positioning block 61; the first material receiving and positioning block 61 is provided with a first adjustment waist-shaped hole 611 extending along its height direction, and the fixed plate 2 is provided with a first threaded hole corresponding to the first adjustment waist-shaped hole 611, and the first adjustment waist-shaped hole 611 and the first threaded hole are provided with the same first locking screw (not shown in the figure); the tension adjustment block 67 is provided with a second threaded hole 671 passing through the upper and lower side walls thereof, and the first limit screw 68 is threadedly connected to the second threaded hole 671, and the end of the first limit screw 68 abuts against the upper surface of the first material receiving and positioning block 61.

[0035] During installation, the first material receiving positioning block 61 is first fixed to the front side of the fixed plate 2 by the first locking screw, and then the tension adjustment block 67 is fixed to the front side of the fixed plate 2 by the screw. When the tension of the material receiving chain 66 needs to be adjusted, since the second material receiving positioning block 62 is fixed on the second-stage movable plate 4, the tension of the material receiving chain 66 can be finely adjusted by adjusting the position of the first material receiving positioning block 61 relative to the fixed plate 2. The specific adjustment steps are as follows: when the material receiving chain 66 needs to be tightened, first loosen the first locking screw so that the first material receiving positioning block 61 can move upward under the guidance of the first adjusting waist-shaped hole 611 (because due to the self-weight of the two-stage movable plate 4, one end of the material receiving chain 66 connected to the second material receiving positioning block 62 will pull the other end of the material receiving chain 66 connected to the first material receiving positioning block 61); then screw the first limiting screw 68 into the second threaded hole 671 from top to bottom. In the process of screwing in the first limiting screw 68, the end of the first limiting screw 68 pushes the first material receiving positioning block 61 downward, and then measures the distance from the lower surface of the tension adjustment block 67 to the upper surface of the first material receiving positioning block 61 by a measuring instrument such as a caliper. After reaching the preset distance, finally lock the first material receiving positioning block 61 on the fixed plate 2 by the first locking screw. Conversely, when the material receiving chain 66 needs to be loosened, the first locking screw is also loosened first, and then the first limiting screw 68 is gradually screwed out of the second threaded hole 671, and the distance between the tension adjustment block 67 and the first material receiving positioning block 61 is measured, and then the first locking screw is re-locked. Through the above settings, the distance between the tension adjustment block 67 and the first material receiving positioning block 61 can be intuitively known through the distance meter, so as to achieve accurate adjustment of the tension of the material receiving chain 66.

[0036] See also Figure 5 and Figure 6Furthermore, a two-stage material receiving slider 42 is provided on the rear side of the one-stage movable plate 3, and a two-stage material receiving slide rail 41 extending along its height direction is provided on the front side of the two-stage movable plate 4, and the two-stage material receiving slider 42 is slidably provided on the two-stage material receiving slide rail 41. The two-stage material receiving slide rail 41 is provided with two, and each of the two-stage material receiving slide rails 41 is provided with more than one two-stage material receiving slider 42. When installing the two-stage material receiving slide rail 41, any one of the two-stage material receiving slide rails 41 is taken as the main guide rail, and the other is taken as the auxiliary guide rail. The side reference of the main guide rail rests on the slide rail installation surface of the two-stage movable plate 4, and then the collimator is used to detect the flatness and straightness of the entire main guide rail, and the accuracy is corrected to make the straightness accuracy corrected to ≤0.02mm / m, and then the auxiliary guide rail is installed and the dial indicator is used to detect the parallelism of the main guide rail and the auxiliary guide rail, and then the auxiliary guide rail is corrected, and the parallelism of the main guide rail and the auxiliary guide rail is ≤0.03mm. By providing the two-stage receiving slide block 42 and the two-stage receiving rail 41, the two-stage movable plate 4 can be smoothly raised or lowered under the guidance of the two-stage receiving rail 41, thereby improving the stability of the receiving plate 7 provided thereon, thereby improving the supporting effect on the pipe fittings.

[0037] See also Figure 5 and Figure 6 Further, the upper part of the front side of the two-stage movable plate 4 is provided with a first-stage two-stage limit seat 43 and a first-stage two-stage anti-collision block 44 arranged below the first-stage two-stage limit seat 43, and the first-stage two-stage anti-collision block 44 is arranged on the rear side of the one-stage movable plate 3; the lower part of the front side of the two-stage movable plate 4 is also provided with a second-stage two-stage anti-collision block 45 and a second-stage two-stage limit seat 46 arranged above the second-stage two-stage anti-collision block 45, and the second-stage two-stage limit seat 46 is arranged on the rear side of the one-stage movable plate 3. Under normal circumstances, the first-stage two-stage limit seat 43 will not contact the first-stage two-stage anti-collision block 44, and similarly, the second-stage two-stage anti-collision block 45 will not contact the second-stage two-stage limit seat 46, that is, the distance between the first-stage two-stage limit seat 43 and the second-stage two-stage limit seat 46 is greater than the moving stroke of the two-stage movable plate 4. The above-mentioned arrangement is used to prevent the one-stage material receiving component 5 from continuously running, and plays a role in limiting the moving stroke of the two-stage movable plate 4.

[0038] See also Figure 3Furthermore, the one-stage material receiving assembly 5 includes a one-stage material receiving drive motor 51, a material receiving transmission gear 9 (not visible in the figure) that is transmission-connected to the output end of the one-stage material receiving drive motor 51, and a material receiving transmission rack 52 that is arranged on the rear side surface of the fixed plate 2 and extends along its height direction, and the material receiving transmission gear is meshed with the material receiving transmission rack 52. When in use, when the one-stage material receiving drive motor 51 rotates forward, it drives the material receiving transmission gear to rotate forward, and under the guidance of the material receiving transmission rack 52, a section of movable plate 3 connected to the one-stage material receiving drive motor 51 is raised. On the contrary, when the one-stage material receiving drive motor 51 rotates reversely, it drives the material receiving transmission gear to rotate reversely, so that a section of movable plate 3 is lowered. The above structure has high transmission efficiency and high transmission accuracy.

[0039] Specifically, the one-stage material receiving drive motor 51 is a servo motor, which has a brake function, which can prevent the large and heavy pipes and the second-stage movable plate 4 from falling due to a sudden power failure of the one-stage material receiving drive motor 51 when cutting, supporting or receiving the pipes, causing safety hazards.

[0040] See also Figure 1 and Figure 2 Further, the upper part of the receiving frame 1 is provided with a first position sensor 11, and the lower part of the side wall of the first movable plate 3 is provided with a first sensing sheet 31 for sensing the first position sensor 11; the lower part of the receiving frame 1 is provided with a second position sensor 12, and the lower part of the side wall of the second movable plate 4 is provided with a second sensing sheet 47 for sensing the first position sensor 11 and the second position sensor 12. The first position sensor 11 and the second position sensor 12 are electrically connected to the control center respectively, and the first receiving drive motor 51 is electrically connected to the control center. When the first sensing sheet 31 on the first movable plate 3 rises to the side of the first position sensor 11, the second movable plate 4 rises to the highest height, the first position sensor 11 transmits the arrival signal to the control center, and the control center transmits the stop signal to the first material receiving drive motor 51 to stop it; when the second movable plate 4 drives the second sensing sheet 47 thereon to descend to the side of the second position sensor 12, the heights of the second movable plate 4 and the first movable plate 3 are the lowest, the second position sensor 12 transmits the arrival signal to the control center, and the control center transmits the stop signal to the first material receiving drive motor 51 to stop it. Through the above settings, precise arrival is achieved. The first position sensor 11 and the second position sensor 12 only show the mounting frame for installing the first position sensor 11 and the second position sensor 12. The first position sensor 11 and the second position sensor 12 are conventional products that can be purchased directly on the market.

[0041] See also Figure 4Furthermore, a receiving motor mounting plate 32 is provided on the rear side of the section of movable plate 3, and a second adjusting waist-shaped hole 321 extending along its width direction is provided on the section of movable plate 3, and a third threaded hole corresponding to the second adjusting waist-shaped hole 321 is provided on the section of movable plate 3, and the same second locking screw (not shown in the figure) is provided in the second adjusting waist-shaped hole 321 and the third threaded hole; an engagement adjustment block 33 is provided on the right side of the receiving motor mounting plate 32, and a first through hole 331 penetrating through the left and right side walls thereof is provided on the engagement adjustment block 33, and the right side of the receiving motor mounting plate 32 is provided with a plurality of second adjusting waist-shaped holes 321 and a plurality of third adjusting waist-shaped holes 321. A fourth threaded hole 322 corresponding to the first through hole 331 is provided on the wall, an adjusting screw 34 is provided in the first through hole 331, and the end of the adjusting screw 34 is threadedly connected with the fourth threaded hole 322 (the outer diameter of the rod body of the adjusting screw 34 is smaller than the aperture of the first through hole 331, and the outer diameter of the head of the adjusting screw 34 is larger than the aperture of the first through hole 331); the meshing degree adjustment block 33 is provided with a fifth threaded hole 332 penetrating the left and right side walls thereof, a second limiting screw 35 threadedly connected in the fifth threaded hole 332, and the end of the second limiting screw 35 abuts against the right side wall of the material receiving motor mounting plate 32. The second adjusting waist-shaped hole 321 and the second locking screw are provided so that the material receiving motor mounting plate 32 and a section of the material receiving drive motor 51 provided thereon can move left and right.

[0042] During installation, first fix the material receiving motor mounting plate 32 on a section of the movable plate 3 through the second locking screw, and then install the meshing adjustment block 33 on a section of the movable plate 3 through the screws. When it is necessary to adjust the meshing degree of the material receiving transmission gear and the material receiving transmission rack 52 that are connected to a section of the material receiving drive motor 51, it can be achieved by fine-tuning the distance between the material receiving motor mounting plate 32 and the meshing adjustment block 33. The specific operation is as follows: first loosen the second locking screw, the adjusting screw 34 and the second limit screw 35, and manually adjust the depth of the adjusting screw 34 into the fourth threaded hole 322 to move the material receiving motor mounting plate 32 to the left or right by a certain distance, and then use a measuring instrument to measure the material receiving motor After the distance between the mounting plate 32 and the meshing adjustment block 33 is adjusted to an appropriate distance, the second limit screw 35 is passed through the fifth threaded hole 332 so that the end of the second limit screw 35 abuts against the right side wall of the material receiving motor mounting plate 32 to locate the position of the material receiving motor mounting plate 32. Then, the material receiving motor mounting plate 32 is fixed to a section of the movable plate 3 by the second locking screw to adjust the meshing degree of the material receiving transmission gear and the material receiving transmission rack 52, thereby adjusting the transmission accuracy of a section of the material receiving component 5 to the highest.

[0043] See also Figure 3Furthermore, the rear side of the fixed plate 2 is provided with a section of material receiving slide rail 21 extending in the height direction thereof, and the front side of the movable plate 3 is provided with a section of material receiving slider 22 slidably connected to the section of material receiving slide rail 21. The section of material receiving slide rail 21 is also provided with two.
