Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a welding auxiliary tooling and a welding robot. Background Art

[0002] Robot welding is an important stage in the development of science and technology. It is a processing method that achieves automatic welding by combining welding equipment with a swivel arm system and a numerical control system. There is no device on the workbench of the existing welding robot that can fix the product to be welded. It is necessary to match it with welding tooling to fix and support the product to be welded. However, it is necessary to consider the positioning of the matching welding tooling and the welding robot. This process is complicated and involves the comprehensive adjustment of the swivel arm system and the numerical control system, which has high professional requirements for the staff. And if the positioning is to be adjusted, it takes a long time to adjust the relevant parameters of the welding robot, swivel arm system and numerical control system, which delays production. However, if it is not repositioned, the positioning of the welding robot will be inaccurate, and automated welding cannot be achieved, which reduces production efficiency. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an automatic welding machine which does not require the welding robot to be repositioned and can cooperate with the welding robot

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A welding auxiliary tool comprises: a base plate, and a concentric shaft with one end fixedly connected to an end surface of the base plate, and the concentric shaft and the base plate are concentric; and a plurality of adjustment devices are detachably connected to the other end surface of the base plate, and the plurality of adjustment devices cooperate with each other for adjustment in multiple directions.

[0006] In one embodiment of the utility model, each of the adjustment devices includes a support plate, and the non-contact end of the support plate and the base plate is provided with an adjustment step, a sliding step and a support step in a stepped form in sequence; the adjustment step is provided with a through hole, the sliding surface of the sliding step is flat, and the supporting surface of the support step is provided in the form of a circular arc surface with a slope, and the circular arc surface fits the bottom of the product to be welded.

[0007] In an embodiment of the utility model, each of the adjustment devices further includes an adjustment handwheel and an adjustment column; the adjustment column is provided with a thread, one end of which is fixedly connected to the handwheel, and the other end passes through the through hole and is threadedly connected to the through hole.

[0008] In an embodiment of the present utility model, each of the adjusting devices further comprises a clamping plate, and the clamping plate is located on the sliding surface of the sliding step; the clamping end of the clamping plate is arranged in a concave arc shape.

[0009] In an embodiment of the present utility model, the adjusting column is fixedly connected to the clamping plate after passing through the through hole, and the hand wheel is rotated so that the adjusting column drives the clamping plate to move on the sliding step.

[0010] In an embodiment of the present invention, the bottom plate is circular.

[0011] In one embodiment of the present invention, a plurality of the adjustment devices are evenly distributed around the center of the circle on the bottom plate.

[0012] In an embodiment of the present invention, the concentric shaft can drive the bottom plate to expand and contract along its own circumference.

[0013] In an embodiment of the present invention, the clamping end of the clamping plate of each of the adjusting devices is in contact with the outer surface of the product to be welded.

[0014] The utility model also provides a welding robot, which uses the welding auxiliary tooling, including a workbench, a concentric shaft whose other end is connected to the workbench of a welding machine, and the concentric shaft, the bottom plate and the workbench are concentric.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the auxiliary device is connected to the workbench of the welding robot, and multiple adjustment devices are adjusted in multiple directions to make the product to be welded concentric with the workbench, avoiding the need to readjust the positioning of the internal program of the welding robot. The welding auxiliary tooling is connected to the welding robot to realize automated welding and improve production efficiency.

[0016] By turning the hand wheel, the adjusting column drives the clamping plate to move on the sliding step to promote the movement of the product to be welded in multiple directions, so that the product to be welded is concentric with the workbench. This not only solves the problem of fixing the product to be welded, but also reduces the difficulty of positioning the welding product and the welding robot. Even general operators can complete the positioning work. BRIEF DESCRIPTION OF THE DRAWINGS
