Description

Technical Field

[0001] The utility model belongs to the technical field of welding auxiliary equipment, and particularly relates to a welding auxiliary clamping device. Background Art

[0002] See in detail Figure 1 The part 40 shown in the figure includes a base 41 and a column 42. Both the column and the base are made of steel, and multiple mounting holes 411 are provided on the base 41; during the production process, the bottom of the column 42 needs to be welded and assembled with the top surface of the base 41 to form an integral part, and there is a definite connection position between the column 42 and the base 41. The current production process is that a worker holds the column 42 by hand, positions it at the connection position of the base 41, and then starts spot welding and positioning around the column 42 with the other hand. After that, the hand holding the part rotates the column and the base to cooperate with the welding torch for circumferential welding; this welding method has a low welding efficiency and is not conducive to short-term and large-scale production.

[0016] To make the purpose, technical solution and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the given embodiments, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0017] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0018] See details in Figure 2-3As shown in the figure, the present application discloses a welding auxiliary clamping device, including a rotating platform 20, a positioning component 30 and a driving component 10; the positioning component 30 is fixedly arranged on the rotating platform 20, and the driving component 10 drives the rotating platform 20 to rotate around a fixed axis. Specifically, the driving component 10 includes a worm and gear reducer 11 and a driving motor 12. The driving motor 12 is fixedly installed on the input flange 111 of the worm and gear reducer 11, and the main shaft of the driving motor 12 is in transmission connection with the worm of the worm and gear reducer 11. Specifically, the mechanism of the worm and gear reducer is the same as that of the prior art and will not be elaborated here; in addition, the positioning component 30 includes a positioning member 31 and a support rod 32. The support rod 32 is fixedly arranged on the rotating platform 20, and the positioning member 31 is fixedly arranged on the support rod 32, and the positioning member 31 is suspended relative to the rotating platform 20. After the positioning member 31 is suspended, an operating space for welding the column and the base can be reserved, avoiding excessive interference with the welding operation.

[0019] Specifically, the positioning member 31 has a vertically arranged positioning surface 31a. In this embodiment, it is preferably that the horizontal section of the positioning member 31 is V-shaped. For example, when the positioning accuracy requirement is not high, equal-angle steel can be used. Through the V-shaped structure, the cylindrical column 42 can be quickly positioned. Of course, it should be noted that by adjusting the position of the positioning surface of the positioning member 31, after the column 42 contacts the positioning surface 31a, the axis of the column 42 coincides with the rotation axis of the rotating platform 20 (the coincidence here is within a certain deviation range, and it can be considered to meet the definition of coincidence).

[0020] In order to better ensure the connection position between the chassis and the column, in this embodiment, it is preferably that the rotating platform 20 is provided with a plurality of positioning columns 21. By adjusting the positions of the positioning columns 21, when the base is placed on the rotating platform, the positioning columns can be inserted into the mounting holes 411 of the base, thereby positioning the base, and then the column and the base can be positioned. In order to enable the mounting holes 411 of the base 41 to be positioned smoothly, in this embodiment, it is preferably that the head end of the positioning column 21 is frustum-shaped.

[0021] In addition, in order to enable the positioning member 31 to stably fix the column, in this embodiment, it is preferably that at least one magnet 33 is arranged on the positioning member 31. Of course, a magnet 33 can be arranged corresponding to each positioning surface 31a. The steel column is magnetically attracted by the magnet 33, and then kept in contact with the positioning surface 31a to prevent it from falling, which is more conducive to the worker to weld it.

[0022] Specifically, in this application, the driving component drives the rotating platform to rotate. The base is placed on the rotating platform, and the column is supported and positioned by the positioning component, replacing manual support of the column. In addition, positioning columns are provided on the rotating platform, and the positioning columns are inserted into the mounting holes of the base to achieve the positioning of the base. Thus, the column is positioned by the positioning component, and the base is positioned by the positioning columns, thereby realizing the rapid positioning of the column and the base and the support of the column. When the driving component drives the rotating platform to rotate, the base and the column are driven to rotate synchronously, and then cooperate with the welding torch for toroidal welding.

[0023] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
