Description

Technical Field

[0001] The utility model relates to the field of steel pipe processing, in particular to a steel pipe weld adjustment mechanism. Background Art

[0002] A vertical steel pipe is usually rolled from a rectangular plate into a pipe body with a gap on the outer wall, and then welded and polished at the gap of the pipe body to make it a hollow steel pipe. However, due to the welding process of the steel pipe, the structural strength at the weld is different from the structural strength at the rest of the steel pipe. When the steel pipe is bent, the bending effect varies depending on the position of the weld. Therefore, in order to ensure the uniform bending effect and reduce the proportion of defective products to reduce production costs, the feeding mechanism of the steel pipe needs to ensure the uniform position of the welds of multiple fed steel pipes to ensure the bending effect of the steel pipe. However, the method of identifying and adjusting by manpower is unrealistic, time-consuming and labor-intensive, and the adjusted position may not be accurate, which is not suitable for adjusting the weld positions of large quantities of steel pipes.

[0003] Therefore, we need a mechanism to adjust the weld position of steel pipes, which can unify the weld positions of multiple steel pipes one by one before processing, and the operation should be accurate and fast to ensure the efficiency and quality of the assembly line without the need for someone to watch over it all the time. Summary of the invention

[0004] In order to solve the above-mentioned technical problems, the purpose of the utility model is to provide a steel pipe weld adjustment mechanism, which, under the control of a controller, adjusts the weld position of the steel pipe without manpower through the mutual cooperation between the adjustment component and the detection element, while ensuring the speed and accuracy of the steel pipe weld adjustment, thereby improving the production quality and efficiency of the bent pipe.

[0007] A frame, which is a support for the adjustment mechanism;

[0008] The adjusting assembly is connected to the frame and includes a driving assembly and an action assembly in contact with the steel pipe, wherein the action assembly is connected to the driving assembly; when the weld of the steel pipe does not conform to the predetermined orientation, the driving assembly can drive the action assembly to make the action assembly drive the steel pipe to rotate circumferentially along its own axis direction, so that the weld of the steel pipe is adjusted to the predetermined orientation;

[0009] The detection element is arranged at a predetermined orientation position of the steel pipe weld, and the detection element can identify the orientation of the steel pipe weld and generate corresponding detection signals according to different orientations of the steel pipe weld;

[0010] A controller; electrically connected to the control element and the drive assembly, and capable of receiving the detection signal;

[0011] The detection element can generate a corresponding detection signal according to the position of the steel pipe weld, and the controller can decide whether to control the driving component to drive the action component to adjust the steel pipe weld according to the received and based on the detection signal.

[0012] Preferably, the action component includes a transmission belt connected to the driving component, and the transmission belt is connected to an action wheel group. The action wheel group tightens the transmission belt, thereby forming two symmetrically arranged receiving bevels in contact with the steel pipe on the transmission belt, and the two receiving bevels together form a V-shaped groove for accommodating the steel pipe; the steel pipe can form a stable support after contacting the receiving bevels in the V-shaped groove, and utilize the friction between the steel pipe and the receiving bevels to drive the steel pipe to rotate circumferentially along its own axis, thereby adjusting the position of the steel pipe weld.

[0013] Preferably, the action wheel group includes three rotating pulleys, one of which is arranged in the middle of the transmission belt and makes the transmission belt concave inward, thereby dividing the transmission belt into two symmetrical inclined belts; the other two rotating pulleys are symmetrically arranged on both sides of the inclined belt, and the two symmetrical inclined belts are close to each other, thereby forming two symmetrical receiving inclined surfaces on the inner sides of the two inclined belts; the two steering pulleys are close to each other, which can form two stable support limit points for the steel pipe, and separate the V-groove from the other rotating pulley, so as to prevent the steel pipe from contacting the other rotating pulley after entering the V-groove.

[0014] Preferably, the driving assembly includes a driving member and a power assembly connected to the driving member, the power assembly includes at least two power pulleys simultaneously connected to the transmission belt, and the driving member is connected to one of the power pulleys; the belt drive has a simple and efficient structure and can easily drive the conveyor belt to move.

[0015] Preferably, the driving member is a servo motor.

[0016] Preferably, the power pulleys are configured in number of three, and the three power pulleys form an inverted triangle accommodating area, and the actuating wheel set is located in the accommodating area; this makes the structure of the entire weld adjustment mechanism more compact and occupies less space.

[0017] Preferably, the detection element is a photosensitive detector, which can emit a detection light beam to illuminate the outer wall of the steel pipe. The detection light beam can identify the different colors of the outer wall of the steel pipe and the steel pipe weld, thereby causing the photosensitive detector to generate a corresponding detection signal. The photosensitive detection method is simple and efficient, and can easily determine the different orientations of the steel pipe weld.

[0018] Preferably, the adjustment components are symmetrically arranged on the frame along the length direction of the steel pipe so that both ends of the steel pipe rotate synchronously, making the adjustment of the steel pipe weld more efficient.

[0021] The beneficial effects of the utility model using the above technical solution are:

DETAILED DESCRIPTION

[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0031] The specific implementation of the utility model is as follows:

[0032] like Figure 1-4 As shown, the utility model provides a steel pipe weld adjustment mechanism, which can adjust the steel pipe weld on the feeding mechanism, the steel pipe weld is a welding mark 5 produced by the steel pipe being bent and welded by a rectangular plate; the feeding mechanism includes a pipe rack 2 symmetrically arranged on the left and right sides, and a row of pipe slots 3 are recessed along the straight line direction on the top of the pipe rack 2 on both sides. After the steel pipe is conveyed to the upper rack 1, the two ends of the steel pipe are respectively placed in the pipe slots 3 on both sides, and a feeding mechanism is also provided on the pipe rack 2, which is used to transport the steel pipe in the pipe slot 3 slot by slot along the arrangement direction of the pipe slot 3.

[0033] Furthermore, limiting plates 11 are provided on both sides of the pipe rack 2, and the limiting plates 11 on both sides clamp the two ends of the steel pipe therebetween. The limiting plates 11 form a two-way limiting effect on the steel pipe to ensure that the position of the steel pipe will not be offset.

[0034] Furthermore, the feeding mechanism includes a rotating arm 12 and a lifting plate 13. The lifting plate 13 is provided with a clamping member 14 with an opening 15 facing the steel pipe. One end of the clamping member 14 with the opening 15 clamps the steel pipe therein, and the other end of the clamping member 14 is fixedly connected to the lifting plate 13; one end of the rotating arm 12 is rotatably connected to the limit plate 11, and the other end is rotatably connected to the lifting plate 13. The rotating arm 12 is provided with a sliding groove 16 with two ends extending therethrough, and the limit plate 11 is provided with a sliding groove 16 connected to the rotating arm 12. An inverted U-shaped limit groove 17 is positioned at the center, and a connecting rod 18 is provided between the rotating arm 12 and the lifting plate 13. One end of the connecting rod 18 is fixedly connected to the lifting plate 13, and the other end of the connecting rod 18 extends a rotating shaft 19 toward the limit plate 11. The rotating shaft 19 passes through the sliding groove 16 and the limit groove 17 and limits the rotating shaft 19 in the sliding groove 16 and the limit groove 17; when feeding, the rotating arm 12 can drive the lifting plate 13 to transport the steel pipe one by one in multiple pipe slots 3 through its own rotation.

[0035] During the steel pipe feeding process, the steel pipe will not rotate circumferentially along its own axis, but the weld of the steel pipe will have different directions. Therefore, in order to adjust the weld direction of the steel pipe, a steel pipe weld adjustment mechanism is set, including:

[0036] Frame 1, frame 1 is the support of the adjustment mechanism; frame 1 is also the support of the feeding mechanism;

[0037] The adjusting component is connected to the frame 1. In order to make the rotation speeds of the two ends of the steel pipe consistent when the weld is adjusted, the adjusting component is symmetrically arranged on the frame 1 along the length direction of the steel pipe so that the two ends of the steel pipe rotate synchronously; so that the adjustment of the steel pipe weld is more efficient; it includes a driving component and an action component in contact with the steel pipe, and the action component is connected to the driving component; when the steel pipe weld does not meet the predetermined direction, the driving component can drive the action component to drive the steel pipe to rotate circumferentially along its own axis direction, so that the steel pipe weld is adjusted to the predetermined direction;

[0038] The detection element 4 is arranged at a predetermined orientation position of the steel pipe weld. The detection element 4 can identify the orientation of the steel pipe weld and generate corresponding detection signals according to different orientations of the steel pipe weld.

[0039] A controller (not shown) is electrically connected to the control element and the drive assembly and can receive the detection signal. When the steel pipe is placed on the action assembly, the detection element 4 can generate a corresponding detection signal according to the position of the steel pipe weld. The controller can decide whether to control the drive assembly to drive the action assembly to adjust the steel pipe weld according to the received detection signal.

[0040] Furthermore, the action component includes a transmission belt 6 connected to the driving component. The transmission belt 6 is usually a belt. The transmission belt 6 is connected to an action wheel group. The action wheel group tightens the transmission belt 6, thereby forming two symmetrically arranged receiving bevels 61 in contact with the steel pipe on the transmission belt 6. The two receiving bevels 61 together form a V-shaped groove 7 for accommodating the steel pipe; the steel pipe can be inserted from the opening of the V-shaped groove 7, and after contacting the receiving bevels 61 in the V-shaped groove 7, a stable support is formed. When the transmission belt 6 moves horizontally, the transmission belt 6 can move horizontally along the V-shaped line. At this time, the steel pipe can use the friction between itself and the receiving bevels 61 to drive the steel pipe to rotate circumferentially along its own axis, thereby adjusting the position of the steel pipe weld.

[0041] Furthermore, the action wheel group includes three rotating pulleys 9, one of which is arranged in the middle of the transmission belt 6, and makes the transmission belt 6 concave inward, thereby dividing the transmission belt 6 into two symmetrical inclined belts; the other two rotating pulleys 9 are symmetrically arranged on both sides of the inclined belt, and make the two symmetrical inclined belts close to each other, thereby forming two symmetrical receiving inclined surfaces 61 on the inner sides of the two inclined belts; since the belt is not a rigid structure, it is easy to deform after it contacts with the steel pipe and supports the steel pipe. Therefore, the two steering pulleys 9 are close to each other, which can form two stable support limit points for the steel pipe, and separate the V-groove 7 from the other rotating pulley 9, so as to avoid the steel pipe from contacting the other rotating pulley 9 after entering the V-groove 7, so that the steel pipe can be stably supported in the V-groove 7.

[0042] Furthermore, the driving assembly includes a driving member 10 and a power assembly connected to the driving member 10. The power assembly includes at least two power pulleys 8 connected to the transmission belt 6 at the same time. The driving member 10 is a servo motor. The driving member 10 is connected to one of the power pulleys 8 and can drive the power pulley 8 to rotate, so that the transmission belt 6 produces stable translational motion and the various rotating pulleys 9 on the rotating wheel group rotate synchronously. Therefore, the structure of this belt drive is simple and efficient, and can easily drive the steel pipe to produce circumferential rotation along its own axis.

[0043] Furthermore, in order to optimize the space of the adjustment mechanism, the power pulleys 8 are configured as three, and the three power pulleys 8 form an inverted triangle accommodating area, and the action wheel group is located in the accommodating area; this design makes the structure of the entire weld adjustment mechanism more compact and occupies less space.

[0044] Furthermore, the color of the steel pipe weld is darker than the color of the outer wall of the steel pipe, so the detection element 4 is usually a light-sensitive detector, which is also called a photoelectric sensor; the light-sensitive detector can emit a detection light beam 41 to illuminate the outer wall of the steel pipe, and the detection light beam 41 can identify the different colors of the outer wall of the steel pipe and the steel pipe weld, thereby causing the light-sensitive detector to generate a corresponding detection signal; the light-sensitive detection method is simple and efficient, and can easily determine the different orientations of the steel pipe weld.

[0045] Furthermore, after the steel pipe enters the V-groove 7, it forms a support with the two receiving inclined surfaces 61. At this time, the steel pipe weld has two situations: conforming to the predetermined orientation and not conforming to the predetermined orientation; when the steel pipe weld is in the predetermined orientation, the photodetector generates a first sensor signal, and the controller receives and does not start the drive component according to the first sensor signal. At this time, the steel pipe will enter the pipe bending processing equipment to proceed to the next processing step; when the steel pipe weld is not in the predetermined orientation, the photodetector generates a second sensor signal, and the controller receives and controls the drive component to drive the action component to work according to the second sensor signal to adjust the weld orientation; when the weld is adjusted to the predetermined orientation, the photodetector generates the first sensor signal again, so that the controller receives again and stops the drive component from continuing to work according to the first sensor signal, thereby avoiding the steel pipe weld from deviating again after being adjusted to the predetermined orientation, thereby ensuring the accuracy of the weld adjustment.

[0046] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
