[0010] Preferably, a plurality of positioning grooves are provided at equal angles on the top of the gear, the gear and the support frame form a locking structure through the positioning grooves and the positioning frame, an inclined surface is provided at one end of the positioning frame close to the inclined push plate, and the positioning frame and the support frame form an elastic structure through a supporting spring.

[0011] In summary, the utility model mainly has the following beneficial effects:

[0012] 1. Existing welding robots are generally fixed on the workbench by screws, which makes it difficult to adjust the welding direction according to welding requirements, thereby limiting the working range and affecting the welding efficiency to a certain extent. The utility model is provided with an adjustment mechanism.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0020] The following describes an embodiment of the utility model based on its overall structure.

[0021] A welding robot capable of multi-angle adjustment, such as Figure 1 and Figure 2 As shown, it includes a welding robot body 1 and a base 2. The base 2 is arranged below the welding robot body 1, and the base 2 is arranged as a hollow structure. The welding robot body 1 is used to perform welding operations on the welding workpiece, which has high work efficiency and flexibility.

[0022] See also Figure 1 and Figure 2 It can be seen that a guide groove 5 is provided at the bottom end of the base 2, and a guide block 4 extending into the guide groove 5 is welded to the bottom end of the tooth plate 302. The tooth plate 302 and the base 2 form a sliding structure through the guide groove 5 and the guide block 4, which can play a supporting and limiting role, thereby increasing the stability of the tooth plate 302 during sliding.

[0023] See also Figure 1 , Figure 2 and Figure 3It can be seen that an adjustment mechanism 3 connected to the welding robot body 1 is provided inside the base 2, and the adjustment mechanism 3 is composed of an electric push rod No. 101, a tooth plate 302, a gear 303 and a support column 304. The inside of the base 2 is rotatably connected to a support column 304 welded to the welding robot body 1 through a bearing, and the outer surface of the support column 304 is welded to a gear 303. The bottom end of the base 2 is movably connected to a tooth plate 302 meshing with the gear 303. The inside of the base 2 is installed with an electric push rod No. 101 welded to the tooth plate 302. During the operation and extension of the electric push rod No. 101, the tooth plate 302 can be moved horizontally, and the gear 303, the support column 304 and the welding robot body 1 can be rotated, so that the angle adjustment of the welding robot body 1 in any direction can be realized, the working range is expanded, and the practicality is improved.

[0024] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be known that the positioning frame 604 and the support frame 601 form an elastic structure through the support spring 606, and the support spring 606 is welded between the positioning frame 604 and the support frame 601. When the gear 303 is working, the No. 2 electric push rod 602 is operated and retracted, so that the inclined push plate 603 moves horizontally to the right. At the same time, the positioning frame 604 is reset and separated from the positioning groove 605 under the action of the support spring 606, thereby releasing the lock on the gear 303.

[0025] See also Figure 1 , Figure 3 and Figure 4 It can be seen that the second electric push rod 602 and the positioning frame 604 are vertically arranged, so that the gear 303 can be prevented from causing damage to the second electric push rod 602, so that the service life of the entire equipment is guaranteed.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4It can be known that a positioning mechanism 6 extending to the inside of the gear 303 is provided at the top of the base 2, and the positioning mechanism 6 is composed of a support frame 601, a No. 2 electric push rod 602, an inclined push plate 603, a positioning frame 604, a positioning groove 605 and a support spring 606. The top of the base 2 is welded with a support frame 601, and a No. 2 electric push rod 602 is installed on the inner side of the support frame 601. An inclined push plate 603 is welded to one side of the No. 2 electric push rod 602. The support frame 601 is slidably connected with a positioning frame 604. A plurality of positioning grooves 605 are provided at equal angles on the top of the gear 303. The gear 303 and the support frame 601 form a clamping structure through the positioning grooves 605 and the positioning frame 604. An end of the positioning frame 604 close to the inclined push plate 603 is provided with an inclined surface.

[0027] Since the welding robot body 1 is prone to causing the gear 303 to move during operation, certain wear is likely to occur between the gear 303 and the tooth plate 302, shortening the service life to a certain extent. At this time, the No. 2 electric push rod 602 is operated and extended, so that the inclined push plate 603 pushes the positioning frame 604 downward and fits into the positioning groove 605, thereby achieving the positioning of the gear 303 through the cooperation between the positioning frame 604 and the positioning groove 605, thereby preventing the gear 303 from moving due to the operation of the welding robot body 1, and reducing the degree of wear between the gear 303 and the tooth plate 302 to a certain extent.

[0028] The working principle of the utility model is as follows: when using the welding robot capable of multi-angle adjustment, the welding operation is performed on the welding workpiece through the welding robot body 1. When the direction needs to be adjusted, the No. 1 electric push rod 301 is started, so that during the operation and extension of the No. 1 electric push rod 301, the tooth plate 302 can be moved horizontally, and the gear 303, the support column 304 and the welding robot body 1 are rotated at the same time, so that the welding robot body 1 can be adjusted to the required direction. At this time, the No. 2 electric push rod 602 is started, so that when the No. 2 electric push rod 602 works and extends, the inclined push plate 603 pushes the positioning frame 604 to move down and snaps into the positioning groove 605, so that the positioning frame 604 and the positioning groove 605 cooperate to realize the positioning of the gear 303, thereby preventing the gear 303 from moving due to the operation of the welding robot body 1. The contents not described in detail in this description belong to the prior art known to professional and technical personnel in this field.
