Welding equipment frame and welding system

Abstract

The present invention provides a welding equipment frame and a welding system, which relate to the technical field of welding equipment. The welding equipment frame includes a first circular beam, a second circular beam, a sliding beam, a plurality of connecting shafts and a deflection control assembly. When the sliding beam moves toward the first circular beam, the connecting shaft applies a supporting force to the sliding beam under the support of the first circular beam, and the supporting force offsets the downward load applied by the welding head to the sliding beam; when the sliding beam moves toward the second circular beam, the deflection control assembly can apply an upward pulling force to the second circular beam, and the pulling force offsets the load applied by the welding head to the second circular beam while keeping the four connecting shafts parallel to each other. The four connecting shafts provide equal supporting force to the sliding beam, thereby ensuring that the sliding beam offsets the gravity load of the welding joint, thereby improving the welding stability of the welding head during the movement of the welding head.

[0027] Combine Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a welding equipment frame, including a first circular beam 1, a second circular beam 2, a sliding beam 3, a plurality of connecting shafts 4 and a deflection control component, the first circular beam 1 is used to connect with a tooling part 30 or a welding part 10, the first circular beam 1 and the second circular beam 2 have the same inner diameter and are coaxially arranged, the length direction of the plurality of connecting shafts 4 is consistent with the axial direction, the two ends of the plurality of connecting shafts 4 are respectively connected to the first circular beam 1 and the second circular beam 2, the plurality of connecting shafts 4 are equidistantly arranged along the circumference of the first circular beam 1, the sliding beam 3 is slidably connected to the plurality of connecting shafts 4, the deflection control component is located above the first circular beam 1, one end of the deflection control component is connected to the first circular beam 1, and the other end extends away from the first circular beam 1 along the radial direction of the first circular beam 1 to the top of the second circular beam 2 and is connected to the second circular beam 2, wherein the first circular beam 1 is used to pass through the welding head 20, the second circular beam 2 is used to pass through the welding cable, and the sliding beam 3 is used to connect with the welding head 20.

[0028] Specifically, take the connection between the first circular ring beam 1 and the tooling 30 as an example. The first connecting beam 1 and the second connecting beam 2 are both circular plate structures, and there are four connecting shafts 4. The four connecting shafts 4 are arranged in parallel with equal intervals. The inner diameter and outer diameter of the first circular ring beam 1 and the second circular ring beam 2 are the same and are arranged coaxially. Any one of the four connecting shafts 4 is parallel to the circumference of the first circular ring beam 1. Both ends of the four connecting shafts 4 are detachably connected to the end faces opposite to the first circular ring beam 1 and the second circular ring beam 2. The four connecting shafts 4 are arranged in parallel with equal intervals between the first circular ring beam 1 and the second circular ring beam 2. The sliding beam 3 is a hollow plate structure. The sliding beam 3 is slidably connected to the four connecting shafts 4. The deflection control The component is located above the first circular ring beam 1, that is, the deflection control component is arranged along the positive direction of the Z axis. The lower end of the deflection control component is detachably connected to the first circular ring beam 1, and the other end extends away from the first circular ring beam 1 along the radial direction of the first circular ring beam 1 and is connected to the second circular ring beam 2. When in use, the first circular ring beam 1 can be installed on the tooling 30 by fasteners such as bolts. The tooling 30 is provided with a through hole that is the same as the inner hole of the first circular ring beam 1. The welding head 20 passes through the through hole of the tooling 30 and the inner hole of the first circular ring beam 1 and contacts with the welding part 10. The inner hole of the second circular ring beam 2 is connected to the sliding beam 3 through the welding cable. When in use, the sliding beam 3 and the welding head 20 on it can be manually pushed to move left and right in the X-axis direction so that the welding head 20 moves toward the welding workpiece 10. When the sliding beam 3 moves toward the negative direction of the X-axis, the distance between the sliding beam 3 and the first circular beam 1 becomes smaller, and the deflection control component only applies tension to the second circular link 2 to keep the four connecting shafts 4 always parallel. The four connecting shafts 4 apply a supporting force to the sliding beam 3 under the support of the first circular beam 1, and the supporting force offsets the downward load applied to the sliding beam 3 by the welding head 20; when the sliding beam 3 moves toward the positive direction of the X-axis, the distance between the sliding beam 3 and the first circular beam 1 becomes larger, and the second circular beam 2 bears the downward load under the action of the gravity of the welding head 20. Since the deflection control component remains stationary under the support of the first circular beam 1, the deflection control component can apply an upward pulling force to the second circular beam 2, which offsets the load applied to the second circular beam 2 by the welding head 20 while keeping the four connecting shafts 4 still parallel to each other.

[0029] In this way, the first circular ring beam 1 is used to connect with the tooling 30 or the welded part 10, so that the first circular ring beam 1 can remain stable to bear the load, and the inner diameters of the first circular ring beam 1 and the second circular ring beam 2 are consistent and coaxially arranged, and the length direction of the plurality of connecting shafts 4 is consistent with the axial direction and connected to the first circular ring beam 1 and the second circular ring beam 2, so that the plurality of connecting shafts 4 remain parallel to each other between the first circular ring beam 1 and the second circular ring beam 2, and then the second circular ring beam 2 can remain stable under the support of the plurality of connecting shafts 4, and the plurality of connecting shafts 4 are arranged at equal intervals along the circumference of the first circular ring beam 1, so as to reduce the load on the first circular ring beam. 1 and the second circular ring beam 2 occupy the circumferential space, and can provide an installation position for the sliding beam 3. After the sliding beam 3 is slidably connected with the multiple connecting shafts 4, the sliding beam 3 can remain stable under the support provided by the multiple connecting shafts 4, and the deflection control component is located above the first circular ring beam 1. One end of the deflection control component is connected to the first circular ring beam 1, and the other end extends away from the first circular ring beam 1 in the radial direction of the first circular ring beam 1 to the top of the second circular ring beam 2 and is connected to the second circular ring beam 2. The deflection control component applies an upward pulling force to the second circular ring beam 2 under the support of the first circular ring beam 1, so that it can be manually The form pushes the sliding beam 3 and the welding head 20 thereon to move in a straight line. When the sliding beam 3 moves toward the first circular beam 1, the distance between the sliding beam 3 and the first circular beam 1 becomes smaller, and the deflection control component only applies tension to the second circular link 2 to keep the four connecting shafts 4 always parallel. The four connecting shafts 4 apply a supporting force to the sliding beam 3 under the support of the first circular beam 1, and the supporting force offsets the downward load applied to the sliding beam 3 by the welding head 20; when the sliding beam 3 moves toward the second circular beam 2, the distance between the sliding beam 3 and the first circular beam 1 becomes larger, and the gravity of the second circular beam 2 under the welding head 20 Under the action of the deflection control component, it bears the downward load. Since the deflection control component remains stationary under the support of the first circular beam 1, the deflection control component can apply an upward pulling force to the second circular beam 2. The pulling force offsets the load applied by the welding head 20 to the second circular beam 2, while keeping the four connecting shafts 4 parallel to each other. The four connecting shafts 4 provide equal support force to the sliding beam 3, thereby ensuring that the sliding beam 3 offsets the gravity load of the welding head 20, so that during the movement of the welding head 20, the welding equipment frame can always provide support force to the welding head 20, thereby improving the welding stability of the welding head 20.

[0030] Optionally, combined Figure 1 and Figure 2As shown, the deflection control assembly includes a connecting frame 7, three lifting ears 8 and a steel wire rope 9.

The other two of the three lifting ears 8 are symmetrically arranged on the second circular ring beam 2 based on the length direction of the connecting frame 7. The steel wire rope 9 is connected to the three lifting ears 8 in a tensioned state.

[0031] Specifically, taking the Z axis as the radial direction of the first circular ring beam 1 as an example, the length direction of the connecting frame 7 is consistent with the Z axis, the lower end of the connecting frame 7 is detachably connected to the first circular ring beam 1, the upper end of the connecting frame 7 extends upward along the positive direction of the Z axis, one of the three lifting ears 8 is detachably connected to the upper end of the connecting frame 7, and the other two of the three lifting ears 8 are symmetrically installed on the second circular ring beam 2 with the length direction of the connecting frame 7 as a reference. The wire rope 9 is connected to the three lifting ears 8 in sequence in a tensioned state. When the second circular ring beam 2 is subjected to a downward load, the right end of the wire rope 9 provides tension to the two lifting ears 8 installed on the second circular ring beam 2 through the lifting ears 8 under the support of the connecting frame 7, and this tension offsets the load borne by the second circular ring beam 2.

[0032] In this way, the length direction of the connecting frame 7 is consistent with the radial direction of the first circular ring beam 1, and one end of the connecting frame 7 is connected to the first circular ring beam 1, and the other end extends away from the first circular ring beam 1 along the radial direction of the first circular ring beam 1, so that the connecting frame 7 provides an installation position for the lug 8 above the first circular ring beam 1, and one of the three lugs 8 is connected to the end of the connecting frame 7 away from the first circular ring beam 1, and the other two of the three lugs 8 are symmetrically arranged on the second circular ring beam 2 based on the length direction of the connecting frame 7, so as to achieve Two stress points are provided on the circular ring beam 2, and then three lifting ears 8 realize forming three stress points on the first circular ring beam 1 and the second circular ring beam 2, and then connected to the three lifting ears 8 in a tensioned state through a steel wire rope 9. In this way, when the second circular ring beam 2 bears the load, the right end of the steel wire rope 9 remains stable on the connecting frame 7 and the lifting ear 8, and the left end of the steel wire rope 9 can apply an upward pulling force to the two lifting ears 8, so that the pulling force on the two lifting ears 8 simultaneously offsets the load on the second circular ring beam 2, thereby improving the structural strength of the second circular ring beam 2.

One end of the first rod 71 is connected to one end of the second rod 72, the other end of the first rod 71 is connected to the first circular beam 1, and the other end of the second rod 72 is connected to the first circular beam 1. One end of the third rod 73 is provided with one of the three lifting ears 8, and the other end is connected to the first rod 71 and the second rod 72 respectively.

[0034] Specifically, the connecting frame 7 has an overall herringbone structure and includes a first rod 71 located in the positive direction of the Y-axis, a second rod 72 located in the negative direction of the Y-axis, and a third rod 73 located in the positive direction of the Z-axis. The first rod 71 and the second rod 72 are symmetrically arranged with the Z-axis as the symmetry line. The upper end of the first rod 71 is connected to the upper end of the second rod 72, the lower end of the first rod 71 is connected to the first circular beam 1 by bolts, and the lower end of the second rod 72 is connected to the first circular beam 1 by bolts. The lower end of the third rod 73 is connected to the upper end of the first rod 71 and the upper end of the second rod 72, and the upper end of the third rod 73 is threadedly connected to one of the three lifting ears 8. When the lifting ears 8 bear the load from the wire rope 9, the lower end of the first rod 71 and the lower end of the second rod 72 can both support the third rod 73 to offset the load borne by the third rod 73, thereby improving the structural strength of the third rod 73 and further ensuring the connection strength between the connecting frame 7 and the first circular beam 1.

A boss 632 is provided at one end where the first section is connected to the second section. The boss 632 is extended along the axial direction of the guide sleeve 63 and is connected to the seat body 61.

[0047] Specifically, taking the connection between the seat body 61 and the first circular ring beam 1 as an example, the guide sleeve 63 is located on the left side of the seat body 61, and the guide sleeve 63 includes a first section located in the positive direction of the Y-axis and a second section located in the negative direction of the Y-axis on the circumference. The lower end of the first section and the lower end of the second section are integrally formed, and a first notch 631 is spaced between the upper end of the first section and the upper end of the second section. The upper end of the first section and the upper end of the second section are both provided with a threaded hole. The threaded direction of the threaded hole is the same, and the bolt 62 is threadedly connected to the upper end of the first section and the upper end of the second section respectively. The lower end of the first section is provided with a boss 632, which extends axially along the guide sleeve 63, that is, extends toward the seat body 61. The right end of the boss 632 is fixedly connected to the seat body 61.
