[0036] In this embodiment, the base 10 is a bearing structure, which is fixedly arranged and suitable for providing installation space for the gantry and the workbench 30. The workbench 30 is a flat plate structure, which is horizontally slidably arranged on the base 10, and the sliding direction is along the X-axis direction of the base 10. The gantry 20 is arranged in an inverted U shape, which is erected on the base 10 along the Y-axis direction of the base 10, and is used to provide a track along the Y-axis for the slide plate 21 arranged thereon. The head 40 is arranged on the slide plate 21 and can move along the Z-axis direction. The above structure is used in combination, so that the stirring head arranged on the head 40 can move up and down along the Z-axis to provide welding operations for the workpiece to be welded arranged at any position on the workbench 30. The first protective cover 70 is arranged between the base 10 and the workbench 30, so as to provide protection for the sliding mechanism of the workbench 30.

[0037] In the above structure, when the workbench 30 slides to one end away from the gantry 20, the workbench 30 is located on one side of the gantry 20. At this time, the overall structure of the workbench 30 is located on the side of the gantry 20, and the first protective cover 70 is completely retracted into the workbench, so that the front, left and right sides of the workbench 30 are all open, thereby facilitating observation and operation by personnel.

[0038] Optionally, the slide 21 is arranged on the side of the gantry 20, the head 40 is arranged on the side of the slide 21, and when the workbench 30 slides to one end away from the gantry 20, the head 40, the slide 21 and the workbench 30 are located on the same side of the gantry 20.

[0039] The spindle gantry welding device 100 provided by the embodiment of the utility model is provided with a workbench 30 movable along the X-axis direction on the base 10, a slide plate 21 slidable along the Y-axis of the base 10 on the gantry 20, and a head 40 mounted on the slide plate 21 and movable along the Z-axis of the base 10, so that the welding operation of the workpiece to be welded fixed on the workbench 30 can be realized by using the stirring head mounted on the head 40. And because the workbench 30 can slide to one side of the gantry 20, it is beneficial for the operator to move the workbench 30 out of the gantry 20 in the middle stage of welding for observation and operation.

[0040] In a specific embodiment, it also includes a controller and a first drive structure, a second drive structure and a third drive structure electrically connected to the controller, the first drive structure is used to drive the workbench 30 to slide along the X-axis, the second drive structure is used to drive the slide 21 to move along the Y-axis, and the third drive structure is used to drive the head 40 to move along the Z-axis.

[0041] Specifically, the first driving structure is a combination structure of a motor and a lead screw slider, wherein the lead screw is arranged on the base 10 along the X-axis direction of the base 10, the workbench 30 is connected to the slider of the lead screw, the motor is connected to one end of the lead screw and can drive the lead screw to rotate, and the rotation of the lead screw drives the slider and the workbench 30 to move back and forth in a straight line on the base 10.

[0042] The second drive structure and the third drive structure also use a motor and screw slider combination structure similar to the first drive structure, wherein the screw in the second drive structure is arranged on the side of the gantry 20 along the Y-axis direction, and the screw in the third drive structure is arranged on the side of the slider along the Z-axis direction.

[0043] The controller is electrically connected to the motors of the first drive structure, the second drive structure and the third drive structure respectively, and is suitable for controlling the movement of the workpiece to be welded along the X direction and the movement of the stirring head along the Y direction and the Z direction by controlling the above-mentioned multiple motors, thereby realizing the control of stir friction welding.

[0044] In a specific embodiment, a cabinet 50 is further included, which is arranged on the side of the gantry 20, and is arranged on both sides of the gantry 20 with the workbench 30 that slides to one side away from the gantry 20, and the controller is arranged in the cabinet 50. In this way, the welding mechanism and the control mechanism can be arranged on both sides of the gantry 20, so that the mutual interference between the two can be avoided, which is not only conducive to welding, but also convenient for control and maintenance operations.

[0045] In a specific embodiment, it also includes a second protective cover 80 and a third protective cover 90 that provide protection for the second drive structure and the third drive structure respectively. The second protective cover 80 is connected to the slide 21 and the gantry 20 respectively, and the third protective cover 90 is connected to the head 40 and the slide 21 respectively.

[0046] Specifically, there are two first protective covers, which are respectively arranged at both ends of the workbench 30, and one end of each first protective cover is connected to the base 10, and the other end is connected to the end of the workbench 30. The above arrangement of the first protective cover 70 enables it to move with the movement of the workbench 30, and thus can always cooperate with the workbench 30 to cover the first driving structure above the base 10, so as to effectively isolate dust and other dirt, thereby ensuring the accuracy of the first driving structure.

[0047] Similarly, the number, connection method and function of the second protective cover and the third protective cover 90 are similar to those of the first protective cover, so they can isolate dust and other dirt from the second drive structure and the third drive structure, thereby ensuring the accuracy of the second drive structure and the third drive structure.

[0048] In a specific embodiment, the first protective cover, the second protective cover and the third protective cover 90 are steel protective covers, bellows covers or aluminum curtains. Steel protective covers, bellows covers or aluminum curtains are all foldable structures, which are not only simple in structure, but also can provide effective protection when used in this embodiment.

[0049] In a specific embodiment, the first protective cover in the same direction as the workbench 30 can be retracted into the workbench 30, the second protective cover 80 in the same direction as the slide can be retracted into the slide 21, and the third protective cover 90 in the same direction as the head 40 can be retracted into the head 40. Through the above arrangement, the influence of the first protective cover, the second protective cover and the third protective cover 90 on the workbench 30, the slide and the head 40 can be further reduced, thereby ensuring the normal operation of the multi-spindle gantry welding equipment 100 with three sides open.

[0050] In a specific embodiment, the stroke of the slide plate 21 is greater than the width of the workbench 30, and both ends of the stroke exceed the edge of the workbench 30 by at least the width of the machine head 40, so that the machine head 40 can be parked on any side of the workbench 30. In this way, the processing of the workpiece to be welded in the edge area of ​​the workbench 30 can be ensured, so that the multi-spindle gantry welding equipment 100 with three sides open can be processed without dead angles.

[0051] In a specific embodiment, the number of the machine heads 40 is at least one. Specifically, the above configuration enables the three-sided open multi-spindle gantry welding device 100 to freely adjust the number of machine heads 40 as needed, thereby enabling directional welding processing.

[0052] In a specific embodiment, when there are two heads 40, the two heads 40 can share the second drive structure and the third drive structure, or the two heads are each connected to a third drive structure and share the same second drive structure. When the two heads 40 can share the second drive structure and the third drive structure, the two heads 40 can be controlled synchronously. When the two heads are each connected to a third drive structure and share the same second drive structure, the two heads 40 can be synchronized in the Y axis but not in the Z axis, which is beneficial to improve welding efficiency.

[0053] In a specific embodiment, the number of the second drive structure and the third drive structure are both two, and each head 40 is connected to a second drive structure and a third drive structure. In this way, the two heads 40 can be controlled separately, which can increase the complexity of the welding operation and facilitate the realization of complex welding work.

[0054] In a specific embodiment, an operation panel 60 is further included, and the operation panel 60 is connected to the gantry 20 and electrically connected to the controller. Optionally, the operation panel 60 is a touch screen operation panel 60 or a button (knob) operation panel. The above arrangement can further simplify the control of the multi-spindle gantry welding device 100 with three sides open, thereby facilitating the improvement of welding efficiency.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
