Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a tubular component clamping device and a welding equipment equipped with the tubular component clamping device. Background Technology

[0002] Existing tubular welding equipment, due to the limited functionality of its clamping devices, cannot achieve alternating stacking welding of tubular components of different sizes. For example... Figure 1 As shown, the tubular component welding equipment 9 includes a frame 91, a welding device 92, and a clamping device 93; wherein, the clamping device 93 includes two clamping mechanisms 931, which are fixedly installed on the frame 91, and the welding device 92 and the two clamping mechanisms 931 are distributed along the axial direction of the tubular component; when it is necessary to weld the first tubular component and the second tubular component, the first tubular component is first clamped and fixed by the two clamping mechanisms 931, and then the first end of the second tubular component is welded and fixed to the end of the first tubular component by the welding device 92. However, since the two clamping mechanisms 931 have the same structure, they can only clamp and fix tubular parts of the same size. When the first tubular part and the second tubular part are different in size, the clamping device 93 cannot clamp the combined structure of the first and second tubular parts after welding. Therefore, it is also impossible to weld the second end of the second tubular part to the first tubular part through the tubular part welding device 9. That is, the tubular part welding device 9 cannot realize the alternating stacking welding of the first tubular part and the second tubular part. Summary of the Invention

[0003] To address the aforementioned problems, the main objective of this invention is to provide a tubular component clamping device that can assist in the alternating stacking and welding of tubular components of different sizes.

[0004] Another objective of this invention is to provide a welding device that enables alternating stacking and welding of tubular components of different sizes.

[0005] To achieve the main objective of this utility model, it provides a tubular clamping device, comprising a clamping mechanism and a clamping and feeding mechanism. The clamping mechanism includes two gripper jaws and a first driving unit. Each gripper jaw has a first positioning jaw and a second positioning jaw. The first driving unit can drive the two gripper jaws to move towards or away from each other in a first direction. A first clamping position can be formed between the first positioning jaws of the two gripper jaws, and a second clamping position can be formed between the second positioning jaws of the two gripper jaws. The clamping and feeding mechanism includes a clamping unit and a second driving unit. The clamping unit includes a first driving module and two symmetrically arranged clamping blocks. Each clamping block has a third positioning jaw. The first driving module can drive at least one clamping block to move towards the other clamping block and form a third clamping position between the third positioning jaws of the two clamping blocks. The first clamping position, the second clamping position, and the third clamping position are arranged coaxially. The second driving unit can drive the clamping unit to move relative to the clamping mechanism in a second direction, which is parallel to the axis of the first clamping position.

[0006] As can be seen from the above, by integrating the first and second positioning jaws on the gripper, and in conjunction with the bidirectional driving characteristics of the first drive unit, it is possible to clamp and stably support tubular components of different diameters. Through the synergistic effect of the clamping unit that can form a third clamping position in the clamping and feeding mechanism and the second drive unit, combined with the design of three coaxial clamping positions, the tubular component clamping device can achieve precise positioning and automatic feeding of tubular components of different specifications in the welding equipment. This effectively ensures the axial alignment accuracy of the joint surface of the tubular components during the alternating stacking welding process, and significantly improves the process adaptability and production efficiency of welding multi-size tubular components.

[0007] In a preferred embodiment, the tubular clamping device further includes a first drive mechanism that can drive the clamping mechanism to move in a second direction.

[0008] As can be seen from the above, by adding a first driving mechanism, the clamping mechanism has an active position adjustment function in the second direction. In conjunction with the clamping mechanism and the clamping feeding mechanism, a motion system that coordinates axial clamping positioning and radial position adjustment is formed.

[0009] A further embodiment is that the first drive unit includes two second drive modules, each corresponding to one of the two gripper components. Each second drive module includes a first guide rail, a first sliding seat, and a first drive source. The first guide rail is parallel to a first direction, the first sliding seat is slidably connected to the first guide rail, and the first sliding seat is equipped with corresponding gripper components. The first drive source can drive the first sliding seat to slide.

[0010] As can be seen from the above, by configuring an independent second drive module for each gripper, bidirectional independent closed-loop control of the gripper in the first direction can be achieved; the split drive mode of each gripper effectively ensures the clamping symmetry, so that the axis of the clamped tubular part always coincides precisely with the clamping position set on the coaxial axis. At the same time, through the coordinated control of the displacement of the two grippers, the radial positioning deviation of the tubular part can be actively corrected.

[0011] A further proposed solution is that the first drive mechanism includes two third drive units, which correspond one-to-one with two second drive modules. Each third drive unit includes a second guide rail, a second sliding seat, and a second drive source. The second guide rail is parallel to a second direction, and the second sliding seat is slidably connected to the second guide rail. The second sliding seat is equipped with a correspondingly arranged second drive module, and the second drive source can drive the second sliding seat to slide.

[0012] As can be seen from the above, by configuring a third drive unit for each second drive module, the synchronicity and smoothness of the movement of the clamping mechanism in the second direction can be better ensured, so as to more accurately ensure the relative position of the two clamping mechanisms.

[0013] A further embodiment is that the first drive source includes a first lead screw, a first nut, a first belt drive assembly, and a first motor. The first lead screw is parallel to a first direction, the first nut is mounted on a first sliding seat and threadedly connected to the first lead screw, the output wheel of the first belt drive assembly is mounted on the first lead screw, and the input wheel of the first belt drive assembly is mounted on the drive shaft of the first motor. The second drive source includes a second lead screw, a second nut, a second belt drive assembly, and a second motor. The second lead screw is parallel to a second direction, the second nut is mounted on a second sliding seat and threadedly connected to the second lead screw, the output wheel of the second belt drive assembly is mounted on the second lead screw, and the input wheel of the second belt drive assembly is mounted on the drive shaft of the second motor.

[0014] As can be seen from the above, by designing the first drive source and the second drive source, the movement of the clamping mechanism in the first direction and the second direction can be precisely controlled, while overload protection can be achieved to avoid damage to the tubular clamping device and / or the tubular component.

[0015] Another preferred embodiment is that the second drive unit includes a third guide rail, a third sliding seat, and a third drive source. The third guide rail is parallel to the second direction, the third sliding seat is slidably connected to the third guide rail, the clamping unit is mounted on the third sliding seat, and the third drive source can drive the third sliding seat to slide. The third drive source includes a third lead screw, a third nut, a third belt drive assembly, and a third motor. The third lead screw is parallel to the second direction, the third nut is mounted on the third sliding seat and threadedly connected to the third lead screw, the output wheel of the third belt drive assembly is mounted on the third lead screw, and the input wheel of the third belt drive assembly is mounted on the drive shaft of the third motor.

[0016] As can be seen from the above, the structural design of the second drive unit enables it to precisely control the movement of the clamping and feeding mechanism to ensure the relative position between the tubular parts, so that the tubular parts can be welded accurately and reliably; at the same time, the design of the third drive source can effectively realize overload protection to avoid damage to the tubular part clamping device and / or the tubular parts.

[0017] A further option is that the first drive module is a cylinder, the cylinder body and a clamping block are both mounted on the third sliding seat, the piston rod of the cylinder is connected to another clamping block, and the piston rod is parallel to the height direction of the tubular clamping device.

[0018] As can be seen from the above, setting the first drive module as a cylinder can better simplify the structure of the clamping and feeding mechanism, reduce production costs and maintenance difficulty.

[0019] A further solution is that the gripper has two or more claws along the second direction, and there is a clearance groove between two adjacent claws, so that the claw of one gripper can be inserted into the clearance groove of another gripper.

[0020] As can be seen from the above, this design ensures that the gripper and the tubular part have sufficient contact area, thereby guaranteeing the reliability of the clamping mechanism in clamping and supporting the tubular part.

[0021] To achieve another objective of this utility model, this utility model provides a welding device, including a welding apparatus, the welding apparatus including a welding head and a second driving mechanism, the second driving mechanism being able to drive the welding head to move in a second direction, wherein the welding device also includes the aforementioned tubular clamping device, in the second direction, a clamping mechanism being located between the welding head and the clamping and feeding mechanism.

[0022] As can be seen from the above, by configuring the aforementioned tubular component clamping device, the welding equipment can achieve alternating stacking welding of tubular components of different sizes, and can ensure the relative positional accuracy between tubular components and the welding reliability, thereby improving the practicality of the welding equipment.

[0023] A further embodiment is that the welding head is provided with a first slot and a second slot. In a second direction, the first slot extends from the end of the welding head near the clamping mechanism into the welding head, and the second slot extends from the bottom of the first slot to the end of the welding head away from the clamping mechanism.

[0024] As can be seen from the above, this design allows the welding head to be used with tubular parts of different sizes, thereby improving the applicability and practicality of the welding device and ensuring that the welding device can perform automated welding of tubular parts of different sizes.

[0033] Welding equipment examples

[0034] Reference Figure 2 The welding equipment 100 includes a frame 10, a tubular clamping device 101, and a welding device 102, both of which are mounted on the table of the frame 10.

[0035] Combination Figure 3 and Figure 4The tubular component clamping device 101 includes a clamping mechanism 1, a clamping and feeding mechanism 2, and a first driving mechanism 3. The clamping mechanism 1 includes two gripper components 11 and a first driving unit 12; the two gripper components 11 are symmetrically arranged, and each gripper component 11 has a first positioning jaw 111 and a second positioning jaw 112. The clamping diameter of the first positioning jaw 111 is larger than the clamping diameter of the second positioning jaw 112, and the clamping axis of the first positioning jaw 111 (i.e., the axis of the clamped tubular component) and the clamping axis of the second positioning jaw 112 (i.e., the axis of the clamped tubular component of another size) are in the same plane. The first positioning jaws 111 of the two gripper members 11 are arranged facing each other in the first direction X. Similarly, the second positioning jaws 112 of the two gripper members 11 are arranged facing each other in the first direction X. When the two gripper members 11 move towards each other in the first direction X, a first clamping position can be formed between the first positioning jaws 111 of the two gripper members 11, or a second clamping position can be formed between the second positioning jaws 112 of the two gripper members 11. Since the clamping tube diameter of the first positioning jaw 111 is different from that of the second positioning jaw 112, the clamping mechanism 1 can clamp and support two tubular parts of different sizes.

[0036] Preferably, the gripper 11 has two or more claw portions 113, a first positioning jaw 111 is formed on the claw portion 113, and at least a portion of the second positioning jaw 112 is formed on the claw portion 113; the two or more claw portions 113 are distributed along a second direction Y, wherein the second direction Y is parallel to the axial direction of the clamped tubular member, such that the first direction X is perpendicular to the second direction Y. A clearance groove 114 is provided between adjacent claw portions 113, such that when the two gripper members 11 move to a certain position, the claw portion 113 of one gripper member 11 can be inserted into the clearance groove 114 of the other gripper member 11. (See [reference needed]). Figure 5 This design ensures that the gripper 11 has a sufficiently large contact area with the tubular component being clamped, thereby guaranteeing the reliability of the clamping mechanism 1 in clamping and supporting the tubular component. At the same time, it ensures that when the second positioning jaw 112 clamps a small-sized tubular component, the gripper 11 will not interfere with each other, thus ensuring the reliability and stability of the second clamping position in clamping and supporting the tubular component.

[0037] The first driving unit 12 is used to drive the two gripper members 11 to move towards or away from each other in the first direction X, so that a first clamping position is formed between the first positioning jaws 111 of the two gripper members 11, or a second clamping position is formed between the second positioning jaws 112 of the two gripper members 11.

[0038] In this embodiment, the first driving unit 12 includes two second driving modules 121, each corresponding to one of the two gripper members 11, such that one second driving module 121 drives one gripper member 11 to move independently in the first direction X. The second driving module 121 includes a first guide rail 1211, a first sliding seat 1212, and a first driving source 1213. The first guide rail 1211 is parallel to the first direction X. The first sliding seat 1212 is slidably connected to the first guide rail 1211, and a corresponding gripper member 11 is mounted on the first sliding seat 1212, so that the gripper member 11 can move with the first sliding seat 1212 in the first direction X. The first driving source 1213 is used to drive the first sliding seat 1212 to slide along the first guide rail 1211, so as to realize that the gripper member 11 controlled by it moves closer or further away from the other gripper member 11.

[0039] By configuring an independent second drive module 121 for each gripper 11, bidirectional independent closed-loop control of the grippers in the first direction X is achieved. The split drive mode of each gripper 11 effectively ensures clamping symmetry, ensuring that the axis of the clamped tubular component always precisely coincides with the clamping position set along the coaxial axis. At the same time, through the coordinated control of the displacement of the two gripper 11s, the radial positioning deviation of the tubular component can be actively corrected. This design not only significantly improves the relative positional accuracy of the joint surfaces of adjacent tubular components, but also enhances the tolerance of the clamping system to fluctuations in the dimensions of the tubular components, ensuring assembly consistency when welding multiple specifications of tubular components alternately.

[0040] Preferably, the first drive source 1213 includes a first lead screw 12131, a first nut 12132, a first belt drive assembly 12133, and a first motor 12134. The first lead screw 12131 is rotatably mounted on the first drive mechanism 3 about its own axis; the first nut 12132 is threadedly connected to the first lead screw 12131 and is mounted on the first sliding seat 1212; the output wheel of the first belt drive assembly 12133 is fixedly mounted on the first lead screw 12131 and the output wheel of the first belt drive assembly 12133 is fixedly mounted on the drive shaft of the first motor 12134, so that the first motor 12134 can drive the first lead screw 12131 to rotate through the first belt drive assembly 12133, and then drive the first sliding seat 1212 to slide along the first guide rail 1211 through the first nut 12132. By designing the first drive source 1213, the movement of the clamping mechanism 1 in the first direction X can be precisely controlled, while overload protection can be achieved to prevent damage to the tubular clamping device 101 and / or the tubular component. In some embodiments, the first drive source 1213 may also be a cylinder, but using a cylinder as the drive source has the disadvantage of not being able to control the position of the gripper 11 more precisely.

[0041] The first driving mechanism 3 drives the clamping mechanism 1 to move in the second direction Y. The addition of the first driving mechanism 3 enables the clamping mechanism 1 to have an active position adjustment function in the second direction Y. This, combined with the clamping mechanism 1 and the clamping feeding mechanism 2, forms a coordinated motion system that integrates axial clamping positioning and radial position adjustment. Specifically, the displacement of the clamping mechanism 1 driven by the first driving mechanism 3 can accurately compensate for axial position deviations during the assembly of tubular components. Combined with the synchronous constraint of the three coaxial clamping positions, it effectively ensures the axial alignment accuracy of tubular components of different specifications during alternating feeding and welding. The synergistic effect of the multi-dimensional driving system not only broadens the range of pipe diameter adaptability but also significantly improves the matching degree of the joint surface in the stacked welding of different diameter pipe components through the dynamic fine-tuning function of the clamping posture, reducing the impact of pipe assembly errors on welding quality.

[0042] The first drive mechanism 3 includes two third drive units 31, which correspond one-to-one with two second drive modules 121, such that one third drive unit 31 drives the corresponding first second drive module 121 and the gripper 11 to move in the second direction Y. The third drive unit 31 includes a second guide rail 311, a second sliding seat 312, and a second drive source 313. The second guide rail 311 is parallel to the second direction Y and is mounted on the frame 10. The second sliding seat 312 is slidably connected to the second guide rail 311, and the second drive module 121 is mounted on the second sliding seat 312. The second drive source 313 is used to drive the second sliding seat 312 to slide, so as to control the clamping mechanism 1 to move in the second direction Y. Because of the distance between the two clamping mechanisms 1, if only one drive unit (usually two clamping mechanisms 1 are mounted on the same sliding seat, and the drive source drives the sliding seat to move in the second direction Y) is used to drive the two clamping mechanisms 1 to move synchronously as a whole, the two clamping components may not be able to maintain synchronous movement in the second direction Y, and may easily get stuck. However, by configuring a third drive unit 31 for each second drive module 121, the synchronicity and smoothness of the movement of the clamping mechanisms 1 in the second direction Y can be better ensured, so as to more accurately ensure the relative position of the two clamping mechanisms 1. Of course, as an alternative, the aforementioned method of using a single drive unit to drive the two clamping mechanisms 1 to move synchronously as a whole can also be adopted.

[0043] The second drive source 313 includes a second lead screw 3131, a second nut 3132, a second belt drive assembly 3133, and a second motor 3134. The second lead screw 3131 is parallel to the second direction Y and is rotatably mounted on the frame 10 around its own axis. The second nut 3132 is threadedly connected to the second lead screw 3131 and is mounted on the second sliding seat 312. The output wheel of the second belt drive assembly 3133 is fixedly mounted on the second lead screw 3131, and the input wheel of the second belt drive assembly 3133 is fixedly mounted on the drive shaft of the second motor 3134, so that the second motor 3134 can drive the second lead screw 3131 to rotate through the second belt drive assembly 3133, and then drive the second sliding seat 312 and its clamping mechanism 1 to move along the second guide rail 311 through the second nut 3132. By designing the second drive source 313 in conjunction with the first drive unit 12, the clamping mechanism 1 can be precisely controlled to move in the first direction X and the second direction Y. At the same time, overload protection can be achieved to prevent damage to the tubular clamping device 101 and / or the tubular component.

[0044] It should be noted that in some embodiments, the first drive unit 12 may use a single drive source to drive the two gripper pieces 11 to move towards each other (usually through a screw and a motor, the screw having two threaded sections with opposite directions of rotation, the two threaded sections being threadedly connected to the two gripper pieces 11 respectively, the motor driving the screw to rotate, so as to drive the two gripper pieces 11 to move towards or away from each other through the screw); however, in this driving method, the two gripper pieces 11 must keep moving towards or away from each other synchronously, and it is easy for the axis of the first clamping position or the second clamping position to be non-collinear with the clamping axis of the clamping and feeding mechanism 2.

[0045] Combination Figure 6 The clamping and feeding mechanism 2 includes a clamping unit 21 and a second driving unit 22. The clamping unit 21 includes a first driving module 211 and two clamping blocks 212. In this embodiment, the two clamping blocks 212 are distributed along the height direction of the tubular component clamping device 101 (i.e., the height direction Z of the welding equipment 100), wherein the height direction Z, the first direction X, and the second direction Y are mutually perpendicular. Distributing the two clamping blocks 212 along the height direction Z allows the clamping blocks 212 to better support and clamp the tubular component.

[0046] A third positioning jaw 2121 is provided on the side of clamping block 212 facing another clamping block 212. The first drive module 211 can drive at least one clamping block 212 to move towards the other clamping block 212, so that a third clamping position is formed between the third positioning jaws 2121 of the two clamping blocks 212. The third clamping position is also used to clamp and support the tubular component. The first clamping position, the second clamping position, and the third clamping position are arranged coaxially. It can be understood that when the clamping mechanism 1 clamps the tubular component through the first clamping position, the first clamping position and the third clamping position are arranged coaxially; when the clamping mechanism clamps the tubular component through the second clamping position, the second clamping position and the third clamping position are arranged coaxially. In this embodiment, the clamping diameter of the third clamping position is preferably equal to the clamping diameter of the first clamping position.

[0047] The second drive unit 22 is used to drive the clamping unit 21 to move relative to the clamping mechanism 1 in the second direction Y, so as to realize the loading and unloading of part of the tubular parts or part of the tubular parts assembly (loading and unloading relative to the clamping mechanism 1).

[0048] In this embodiment, the second drive unit 22 includes a third guide rail 221, a third sliding seat 222, and a third drive source 223. The third guide rail 221 is parallel to the second direction Y and is mounted on the table of the frame 10. The third sliding seat 222 is slidably connected to the third guide rail 221, and the clamping unit 21 is mounted on the third sliding seat 222. Preferably, the first drive module 211 is a cylinder. The cylinder body and a clamping block 212 of the first drive module 211 are both mounted on the third sliding seat 222. The piston rod of the cylinder is parallel to the height direction Z, and the other clamping block 212 is connected to the piston rod of the cylinder, so that the first drive module 211 can drive the clamping block 212 to move towards the other clamping block 212 in the height direction Z, thereby forming a third clamping position at the third positioning jaws 2121 of the two clamping blocks 212. Setting the first drive module 211 as a cylinder can better simplify the structure of the clamping and feeding mechanism 2, reduce production costs and maintenance difficulty.

[0049] The third drive source 223 is used to drive the third sliding seat 222 to slide, so that the third sliding seat 222 drives the clamping unit 21 and the tubular part or tubular part assembly clamped by the clamping unit 21 to feed or unload onto the clamping mechanism 1. Preferably, the third drive source 223 includes a third lead screw 2231, a third nut 2232, a third belt drive assembly 2233, and a third motor 2234; the third lead screw 2231 is parallel to the second direction Y and is rotatably mounted on the platform of the frame 10 around its own axis; the third nut 2232 is threadedly connected to the third lead screw 2231 and is fixedly connected to the third sliding seat 222 to drive the third sliding seat 222 to move; the output wheel of the third belt drive assembly 2233 is fixedly connected to the third lead screw 2231, and the input wheel of the third belt drive assembly 2233 is fixedly connected to the drive shaft of the third motor 2234, so that the third motor 2234 can drive the third lead screw 2231 to rotate through the third belt drive assembly 2233, thereby controlling the third sliding seat 222 and the clamping unit 21 on it to move relative to the clamping mechanism 1. The second drive unit 22 is designed to precisely control the movement of the clamping and feeding mechanism 2 to ensure the relative position between the tubular parts, enabling precise and reliable welding between them. Meanwhile, the design of the third drive source 223 can effectively achieve overload protection, preventing damage to the tubular part clamping device 101 and / or the tubular parts.

[0050] The tubular component clamping device 101 integrates a first positioning jaw 111 and a second positioning jaw 112 on the jaw member 11. Combined with the bidirectional driving characteristics of the first driving unit 12, it can clamp and stably support tubular components of different diameters. In addition, through the synergistic effect of the clamping unit 21, which can form a third clamping position in the clamping and feeding mechanism 2, and the second driving unit 22, combined with the design of three coaxial clamping positions, the tubular component clamping device 101 can achieve precise positioning and automatic feeding of tubular components of different specifications in the welding equipment 100. This effectively ensures the axial alignment accuracy of the joint surface of the tubular components during the alternating stacking welding process, and significantly improves the process adaptability and production efficiency of welding processing of multi-size tubular components.

[0051] Combination Figure 7 The welding device 102 includes a welding head 4 and a second driving mechanism 5. In the second direction Y, the clamping mechanism 1 is located between the welding head 4 and the clamping and feeding structure. The second driving mechanism 5 is used to drive the welding head 4 to move relative to the clamping mechanism 1 in the second direction Y so as to perform welding processing on the tubular part clamped by the clamping mechanism 1.

[0052] Preferably, the welding head 4 is provided with a first slot 41 and a second slot 42. In the second direction Y, the first slot 41 extends from the end of the welding head 4 near the clamping mechanism 1 into the welding head 4, and the second slot 42 extends from the bottom of the first slot 41 towards the end of the welding head 4 away from the clamping mechanism 1. This design allows the welding head 4 to be used with tubular parts of different sizes, thereby improving the applicability and practicality of the welding device 102 and ensuring that the welding device 102 can perform automated welding of tubular parts of different sizes.

[0053] In summary, by configuring the aforementioned tubular component clamping device 101, the welding equipment 100 can achieve alternating stacking welding of tubular components of different sizes, ensure the relative positional accuracy between tubular components and the welding reliability, and improve the practicality of the welding equipment 100.

[0054] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
