Description

Technical Field

[0001] The utility model relates to the technical field of plate welding, in particular to a vertical cross welding manipulator. Background Art

[0002] The vertical cross welding manipulator is a device that welds materials such as plates and pipes together. It achieves multi-directional welding of plates through a mechanical arm that can adjust the up and down and left and right positions.

[0003] The vertical cross welding manipulator commonly used in enterprises includes a mounting base, a vertical slide rail on the mounting base, a transverse robotic arm on the vertical slide rail, and a welding head on the transverse robotic arm. The horizontal and vertical positions of the welding head are adjusted by moving the transverse robotic arm up and down on the vertical slide rail and the welding head horizontally on the transverse robotic arm to weld the plates.

[0004] However, the horizontal robotic arm of the vertical cross welding manipulator can generally only maintain a horizontal state. When facing some welding at inclined angles, such as welding an inclined trough, the horizontal robotic arm cannot be inserted into the trough for welding, and the welding function is limited. In order to increase the welding range of the vertical cross welding manipulator, a new type of vertical cross welding manipulator is proposed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a vertical cross welding manipulator, which is used to solve the problem that the horizontal mechanical arm of the vertical cross welding manipulator commonly used in enterprises can generally only maintain a horizontal state and cannot be used for welding at an inclined angle.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A vertical cross welding manipulator comprises a base, a vertical slide rail vertically arranged on the base, a slide seat slidably connected to the vertical slide rail, a mounting seat rotatably connected to the front of the slide seat, and a horizontal mechanical arm installed on the mounting seat, wherein connecting frames are arranged on both sides of the slide seat, and the ends of the connecting frames are fixedly connected to the inner wall of the circular track, and fixing rods are fixedly arranged on the upper surface and the lower surface of the mounting seat, and the ends of the fixing rods are movably sleeved on the surface of the circular track, and a locking mechanism for the circular track is arranged on the fixing rod, and a sliding block slidably connected to the vertical slide rail is arranged on the back of the circular track.

[0008] Preferably, the locking mechanism comprises a bolt threadedly connected to the top end of the fixing rod and an extrusion block rotatably connected to the bolt and supported in an upper limit groove on the circumferential outer wall of the annular track.

[0009] Preferably, the surface shape of the extrusion block away from the bolt is matched with the limiting groove.

[0010] Preferably, the front side of the annular track is provided with scales.

[0011] Preferably, the fixing rod is provided with an observation slot with corresponding scale.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model provides a circular track fixed outside the slide to perform specific comparison on the rotation angle of the mounting seat, so as to facilitate obtaining the data of the rotation angle. During the rotation of the mounting seat, the mounting seat is supported by the fixing rod, and the transverse mechanical arm is installed on the mounting seat to ensure the stability of the mounting seat during rotation. After the rotation is completed, the circular track is locked by bolts and extrusion blocks to ensure the fixing effect of the circular track. Compared with a welding head that can only be adjusted up, down, left and right, the welding head at the end of the transverse mechanical arm of the utility model can be adjusted up and down, has a larger range of use, and is adaptable to more welding situations. It solves the problem that the transverse mechanical arm of the vertical cross welding manipulator commonly used in enterprises can generally only maintain a horizontal state and cannot be used for welding at an inclined angle.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-3As shown, the utility model provides a technical solution: a vertical cross welding manipulator, comprising a base 1, a vertical slide rail 2 vertically arranged on the base 1, a slide seat 3 slidably connected to the vertical slide rail 2, a mounting seat 4 rotatably connected to the front of the slide seat 3, and a horizontal mechanical arm 5 installed on the mounting seat 4;

[0020] Connecting frames 6 are provided on both sides of the slide 3, and the ends of the connecting frames 6 are fixedly connected to the inner wall of the annular track 7. The slide 3, the connecting frames 6, the annular track 7 and the sliding block 10 slide on the vertical slide rail 2. The front of the annular track 7 is provided with a scale 702, through which the rotation angle of the mounting seat 4 can be observed, so that the user can adjust the angle of the mounting seat 4 more accurately.

[0021] A fixing rod 8 is fixedly provided on the upper surface and the lower surface of the mounting seat 4. The fixing rod 8 is provided with an observation slot 801 corresponding to the scale 702. The scale 702 is observed through the observation slot 801. By comparing the different angles of the scale 702 in the observation slot 801, the rotation data can be understood.

[0022] The end of the fixing rod 8 is movably sleeved on the surface of the annular track 7, and the fixing rod 8 is provided with a locking mechanism 9 for the annular track 7, the locking mechanism 9 comprises a bolt 901 threadedly connected to the top of the fixing rod 8 and an extrusion block 902 rotatably connected to the bolt 901 and supported in the upper limit groove 701 of the circumferential outer wall of the annular track 7, by screwing the bolt 901, the lower end of the bolt 901 drives the extrusion block 902 to move toward the bottom of the limit groove 701, and after the extrusion block 902 contacts the limit groove 701, the extrusion block 902 applies pressure to the bottom of the inner wall of the limit groove 701, thereby fixing the fixing rod 8;

[0023] The surface shape of the extrusion block 902 away from the bolt 901 is adapted to the limiting groove 701, thereby increasing the contact area between the extrusion block 902 and the limiting groove 701 to ensure the relative friction between the extrusion block 902 and the limiting groove 701. A sliding block 10 slidably connected to the vertical slide rail 2 is provided on the back of the annular track 7.

[0024] Working principle:

[0025] Rotate the mounting base 4, and the mounting base 4 drives the rotation of the transverse robot 5 to change the angle of the welding head on the transverse robot 5. The rotation of the mounting base 4 drives the fixing rod 8 to move on the annular track 7, and the data of the rotation angle is obtained by comparing the scale 702. After the rotation of the mounting base 4 is completed, the extrusion block 902 is driven to extrude by tightening the bolt 901, so that the extrusion block 902 descends and contacts the inner wall of the limit groove 701 for extrusion positioning, thereby fixing the fixed rod 8 after adjustment, ensuring the stability of the mounting base 4 after rotation, and realizing angle adjustment.
