Description

Technical Field

[0001] The utility model relates to the field of laser welding equipment, and more specifically, to a laser welding device. Background Art

[0002] Current laser welding equipment generally has an X-axis drive, a Y-axis drive, and a Z-axis drive on the welding support frame. The three drives drive the laser welding joint to facilitate welding of the welded parts on the laser welding table.

[0003] However, with the deepening of application, people found that since the welding support frame requires X-axis, Y-axis and Z-axis drivers, the welding support frame will bear a large load. In addition, even if the Y-axis driver is separated, since the welding support frame is also equipped with X-axis and Z-axis drivers, when the Z-axis driver needs to move up and down, if it is only supported by the X-axis screw slide, since the length of the X-axis screw slide is fixed, when the Z-axis driver only has a supporting function on one side, in the process of the laser welding joint moving up and down, the bottom of the Z-axis driver is prone to lack of support, resulting in uneven force on both sides of the Z-axis driver. Over time, the Z-axis driver will be easily damaged.

[0004] Therefore, it is necessary to propose a laser welding device that solves the above problems. Utility Model Content

[0005] The present invention provides a laser welding device to overcome at least one defect (shortcoming) of the prior art.

[0006] In order to solve the above technical problems, the technical solution of the present utility model is as follows: a laser welding device, comprising a laser welding table, a laser welding joint, a welding support frame arranged on the laser welding table, and a welding part bearing seat for bearing the welded part;

[0007] A Y-axis servo driver is provided at the bottom of the welding part bearing seat, and the welding part bearing seat is movably arranged on the laser welding table along the Y-axis direction by the driving of the Y-axis servo driver;

[0008] The welding support frame is provided with an X-axis driver and a plurality of height adjustment holes, and the height adjustment holes are provided with a detachable auxiliary guide slider;

[0009] The X-axis driver is provided with a Z-axis servo driver, the laser welding joint is arranged on the front of the Z-axis servo driver, and the back of the Z-axis servo driver is connected to the auxiliary guide slider through a connecting block. Since the welding part carrier is movably arranged on the laser welding table by the drive of the Y-axis servo driver, only the X-axis driver and the Z-axis servo driver need to be set on the welding support frame to control the laser welding joint in the X-axis and Z-axis directions, thereby welding the welding parts carried on the welding part carrier. Since the setting of the Y-axis servo driver is reduced, the counterweight can be reduced, thereby simplifying the overall structure of the welding support frame. In addition, the welding support frame is further provided with an auxiliary guide slider between the X-axis driver and the Z-axis servo driver. The setting of the auxiliary guide slider allows the Z-axis servo driver to be better installed and also makes the force on both sides of the Z-axis servo driver more uniform.

[0010] Furthermore, the auxiliary guide slider includes an auxiliary mounting seat, a guide slide rail, a first mounting block, a second mounting block and a barb block;

When the screw passes through the screw hole, the screw is pressed between the first mounting block and the second mounting block, so that the hook blocks on the first mounting block and the second mounting block are clamped at the end of the height adjustment hole. Through the auxiliary mounting seat and the guide sliding rail, the Z-axis servo drive can be strengthened to support and guide. Since the side of the welding support frame is provided with a screw hole, when the first mounting block, the second mounting block and the hook block are inserted into the height adjustment hole, the screw is inserted into the screw hole. Since the insertion of the screw will stretch the first mounting block and the second mounting block to a certain extent, the hook blocks on the first mounting block and the second mounting block are clamped at the end of the height adjustment hole, thereby positioning the installation of the auxiliary guide slider.

[0014] Furthermore, the cross-section of the screw is conical. Since the cross-section of the screw is conical, when the screw is fully inserted and installed, the first mounting block and the second mounting block will be separated, so that the barb blocks on the first mounting block and the second mounting block are stuck at the end of the height adjustment hole.

[0015] Furthermore, the connecting block includes a connecting block body, a positioning screw hole, a positioning screw and a slot provided on the connecting block body;

[0016] The Z-axis servo driver is provided with a positioning hole, the positioning screw hole is provided on the connecting block body, and the positioning screw passes through the positioning screw hole on the connecting block body and is fixed on the positioning hole of the Z-axis servo driver;

By rotating the X-axis driving wheel, the X-axis screw rotates, thereby driving the X-axis screw slide to move in the direction of the X-axis. Since the X-axis driver adopts manual control, it can be adjusted according to the needs, which is simple and convenient.

[0021] Furthermore, the Y-axis servo driver includes a Y-axis servo motor, a Y-axis lead screw slide, a Y-axis lead screw, and a Y-axis driver mounting seat arranged on the laser welding table;

[0022] The Y-axis servo motor is arranged on the Y-axis driver mounting seat, the Y-axis lead screw is connected to the Y-axis servo motor, and the Y-axis lead screw slide is arranged on the Y-axis lead screw;

[0023] The welding part bearing seat is installed on the Y-axis screw slide, and the Y-axis screw is driven to rotate by the Y-axis servo motor, so that the Y-axis screw slide on the Y-axis screw moves in the Y-axis direction, thereby adjusting the position of the welding part bearing seat.

[0024] Furthermore, the Z-axis servo driver includes a Z-axis driver mounting base, a Z-axis screw slide, a Z-axis screw and a Z-axis servo motor;

[0029] Furthermore, a controller is provided on the laser welding table, and the controller is connected to the Y-axis servo driver, the Z-axis servo driver and the laser welding joint. Through the controller, the Y-axis servo driver, the Z-axis servo driver and the laser welding joint can be controlled, thereby facilitating the welding of the welding parts carried by the welding part supporting seat.

[0030] Furthermore, it also includes a supporting foot with an external thread. A threaded hole is provided at the bottom of the laser welding table. The supporting foot is arranged in the threaded hole of the laser welding table with an adjustable height through the external thread. Through the setting of the supporting foot, when the laser welding table is moved into place, the supporting foot can be lowered, thereby facilitating the support of the laser welding table.

[0031] Furthermore, a guide wheel is provided at the bottom of the laser welding table. The provision of the guide wheel facilitates the movement and transportation of the laser welding table, which is simple and convenient.

[0032] Compared with the prior art, the beneficial effects of the technical solution of the utility model are:

[0051] Example

[0052] In this embodiment, when the welding part needs to be welded, the welding part can be placed on the welding part supporting seat and fixed. When the Y-axis servo motor is driven, the Y-axis servo motor drives the Y-axis screw to rotate. At this time, the Y-axis screw will drive the Y-axis screw slide to move along the Y-axis direction. Since the welding part supporting seat is set on the Y-axis screw slide, the welding part supporting seat carries the welding part to move back and forth along the Y-axis direction.

[0053] Since the X-axis driver and the auxiliary guide slider are respectively arranged at the upper and lower ends of the welding support frame, the X-axis drive wheel is rotated to rotate the X-axis lead screw connected to the X-axis drive wheel, thereby driving the X-axis lead screw slide to move in the direction of the X-axis. Since the Z-axis driver mounting seat of the Z-axis servo driver is arranged on the X-axis lead screw slide, when the X-axis lead screw slide moves into place, the Z-axis servo motor drives the Z-axis lead screw to rotate, so that the Z-axis lead screw slide on the Z-axis lead screw can move up and down along the Z-axis driver mounting seat, thereby adjusting the position of the laser welding joint in the direction of the Z-axis. Since the X-axis, Y-axis and Z-axis have all been adjusted, the laser welding joint can be welded after the welding pipeline equipment is connected. Since the setting of the Y-axis servo driver is reduced on the welding support frame, the counterweight can be reduced, thereby simplifying The overall structure of the welding support frame is optimized. In addition, the welding support frame is provided with an auxiliary guide slider between the X-axis drive and the Z-axis servo drive. The setting of the auxiliary guide slider allows the Z-axis servo drive to be better installed, and also makes the force on the upper and lower sides of the Z-axis servo drive more uniform. When the auxiliary guide slider needs to be fixed, a screw is inserted into the screw hole. Since the insertion of the screw will stretch the first mounting block and the second mounting block to a certain extent, the barb blocks on the first mounting block and the second mounting block are clamped at the end of the height adjustment hole, thereby positioning the installation of the auxiliary guide slider. The cross-section of the screw is conical. Since the cross-section of the screw is conical, when the screw is fully inserted and installed, the first mounting block and the second mounting block will be separated, so that the barb blocks on the first mounting block and the second mounting block are clamped at the end of the height adjustment hole.
