Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, and particularly relates to an automatic welding equipment for a bed body component of a laser cutting equipment. Background Art

[0002] Laser welding is a technology that uses a laser beam with a high energy density as a heat source. By focusing and regulating the irradiation on the material surface, the material is locally heated, melted, and then cooled and solidified to achieve connection. This technology has the advantages of high precision, high efficiency, and low heat-affected zone. However, in existing laser welding, the position to be welded is manually adjusted, resulting in a large workload for welders and a low overall work efficiency.

[0003] A patent with the publication number CN220480682U relates to an automatic welding equipment, including a box body. A support plate is arranged inside the box body, and two second electric telescopic rods are fixedly installed on the inner wall of the box body. The two second electric telescopic rods are arranged on both sides of the support plate; the telescopic shafts of the two second telescopic rods face each other, and the telescopic shafts of the two second telescopic rods are both fixedly connected with a first clamping plate; a connecting plate is fixedly connected to the top of each of the two first clamping plates, a threaded rod is vertically threaded through each connecting plate, a rotating plate is fixedly arranged at the top of the threaded rod, and a second clamping plate is fixedly arranged at the bottom of the threaded rod.

[0004] In the above solution, the two first clamping plates are driven by the second electric push rod to move towards each other, so as to clamp and fix the workpiece in the horizontal direction. Then, the rotating plate is rotated to drive the second clamping plate to move downward, so as to clamp and fix the workpiece in the vertical direction. However, two different operations are required for the comprehensive limiting and fixing of the workpiece, and there is no association between the two operations, resulting in an increased workload for the staff. Therefore, the whole operation is cumbersome, the degree of automation is low, and there are certain limitations in actual use. Summary of the Utility Model

Two sliding grooves are symmetrically opened on the top of the bottom plate 1. The two first clamping mechanisms are both in limiting sliding fit with the two sliding grooves one by one, and are also in threaded connection with the two threaded sections of the bidirectional lead screw 4 one by one. By driving the two first clamping mechanisms to approach each other through the motor 3, the workpiece is clamped and limited in the horizontal direction.

[0025] Each first clamping mechanism includes a first moving plate 5. Both first moving plates 5 are slidably arranged on the top of the bottom plate 1.

One end of the first spring 7 is fixedly connected to the first moving plate 5, and the other end of the first spring 7 is fixedly connected to the first clamping plate 8.

[0027] Two fixed frames 19 are fixedly erected on the top of the bottom plate 1. A limiting groove is opened on the side of each of the two fixed frames 19 facing the workpiece placement groove. A second clamping mechanism is both slidably arranged in the two limiting grooves in the vertical direction and a lead screw 13 is rotatably arranged in the vertical direction. The top of the lead screw 13 is rotatably connected to the fixed frame 19. The lead screw 13 and the bidirectional lead screw 4 are in transmission cooperation through a transmission member.

[0028] The second clamping mechanism includes a second moving plate 14. The second moving plate 14 is slidably arranged in the limiting groove in the vertical direction. The part of the second moving plate 14 located in the limiting groove is in threaded connection with the lead screw 13 in the limiting groove. In addition, a second clamping plate 17 is fixedly arranged on the side of the second moving plate 14 facing the bottom plate 1 through a second elastic member.

[0029] The second elastic member includes a second telescopic rod 15. The second telescopic rod 15 is fixedly arranged on the second moving plate 14. One end of the second telescopic rod 15 close to the bottom plate 1 is fixedly connected to the second clamping plate 17. A second spring 16 is arranged between the second moving plate 14 and the second clamping plate 17. The second spring 16 is sleeved on the outer surface of the part of the second telescopic rod 15 between the second moving plate 14 and the second clamping plate 17. The telescopic direction of the second spring 16 is the same as that of the second telescopic rod 15. One end of the second spring 16 is fixedly connected to the second moving plate 14, and the other end is fixedly connected to the second clamping plate 17.

[0030] A first bevel gear 9 is fixedly sleeved on the outer surface of the bidirectional lead screw 4. The bottom of the lead screw 13 rotates through the inside of the bottom plate 1 and is coaxially and fixedly provided with a fourth bevel gear 20. The transmission member includes a connecting rod 10. The connecting rod 10 is rotatably arranged in the bottom plate 1 in the horizontal direction. Both ends of the connecting rod 10 are rotatably connected to the bottom plate 1. A second bevel gear 11 and a third bevel gear 12 are both fixedly sleeved on the outer surface of the connecting rod 10. The second bevel gear 11 and the first bevel gear 9 are in one-to-one meshing transmission, and the third bevel gear 12 and the fourth bevel gear 20 are in one-to-one meshing transmission.

[0031] In addition, a control panel 2 and a welding robot 18 are also installed on the top of the bottom plate 1. The motor 3 is electrically connected to the control panel 2.

The welding robot belongs to the prior art, and this solution will not describe it in detail.

[0032] Working principle: When welding a workpiece is required, place the workpiece in the workpiece placement groove. Start the motor 3 through the control panel 2. The output shaft of the motor 3 drives the bidirectional lead screw 4 to rotate. The bidirectional lead screw 4 drives the two first moving plates 5 to approach each other, so as to push the two first clamping plates 8 to approach each other through the first spring 7, and then clamp and fix the workpiece in the horizontal direction.

[0033] At the same time, the rotation of the bidirectional lead screw 4 will also drive the second bevel gear 11 to rotate through the first bevel gear 9, so as to drive the third bevel gear 12 to rotate through the connecting rod 10. The rotation of the third bevel gear 12 will drive the lead screw 13 to rotate through the fourth bevel gear 20. The rotation of the lead screw 13 will drive the second moving plate 14 to slide in the direction close to the bottom plate 1, so as to push the second clamping plate 17 to move synchronously through the second spring 16, and then clamp and fix the workpiece in the vertical direction.

[0034] After the workpiece is clamped and fixed, adjust the position of the welding head on the welding robot 18 through the external PLC control system, so as to automatically weld the workpiece, improve the overall welding efficiency and reduce the burden on welders.

[0035] In addition, through the arrangement of the first spring 7 and the second spring 16, the first clamping plate 8 and the second clamping plate 17 can be used to clamp workpieces of more sizes. For example, when the workpiece is too high, the second clamping plate 17 contacts the top of the workpiece first. At this time, by using the contraction of the second spring 16 and the second telescopic rod 15, the staff can also control the two first clamping plates 8 to approach each other, so as to complete the horizontal and vertical clamping and limiting of the workpiece, and thus be applicable to workpieces of more sizes.

[0036] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
