Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] like Figure 1 and Figure 3 As shown, this application provides a welding positioning device, which is mainly used for welding operations of various metal parts on a road roller. The welding positioning device includes a base 1, and a lifting component 2 is provided on the base 1. The lifting component 2 is used to lift subsequent equipment.

[0031] The lifting assembly 2 comprises a lifting module 21 arranged on the base 1, which is driven by the existing ball screw and linear guide as a transmission mechanism, and by a driving device as a power source, which can be a motor or a hydraulic motor. The specific structure and working principle are prior art and will not be described in detail here.

[0032] Meanwhile, the device frame 22 is installed at the output end of the lifting module 21, and two groups of rotating rods 27 are bearing-mounted on the device frame 22, and a fixed frame 25 is fixedly installed between the two groups of rotating rods 27, and a welding table 23 is fixedly installed on the fixed frame 25, so that the device frame 22 is driven to move up and down under the driving of the lifting module 21, thereby driving the welding table 23 to move up and down synchronously through the rotating rods 27.

[0033] Continuing to refer to Figure 3 A servo motor 24 is fixedly installed on the device frame 22, and a belt drive set 26 is co-arranged on one of the two groups of rotating rods 27 at the output end of the servo motor 24, so that the rotating rod 27 is driven to rotate through the belt drive set 26 under the driving of the servo motor 24, thereby driving the welding table 23 to rotate.

[0034] As shown in Figures 1-2 A clamping assembly 3 is arranged on the welding table 23, which is used for clamping workpieces. The clamping assembly 3 comprises two groups of sliding rails 37 fixedly installed on the welding table 23, which are oppositely arranged. A bottom plate 36 is slidingly arranged on the two groups of sliding rails 37, and a disc 33 is fixedly installed on the bottom plate 36. A stepping motor is fixedly installed in the inside of the disc 33, and a rotating shaft (not shown in the figure) is fixedly installed at the output end of the stepping motor. The rotating shaft extends out of the disc 33 and is adapted to rotate under the driving of the stepping motor.

[0035] Meanwhile, a support seat 32 is fixedly installed on the rotating shaft, and a clamping part 31 is arranged on the support seat 32, which can be a flat tongs, so that the clamping part 31 can rotate with the rotating shaft.

[0036] Continuing to refer to Figure 2 An angle scale 34 is arranged on the disc 33, and a reading ruler 35 is fixedly installed on the support seat 32, which is aligned with the angle scale 34, so that the support seat 32 is driven to rotate synchronously when the support seat 32 rotates, thereby driving the workpiece to rotate, and the angle of the support seat 32 rotating can be read through the cooperation of the reading ruler 35 and the scale, so as to obtain the angle of the workpiece rotating.

[0037] In summary, when welding, the workpieces to be welded are placed on the two sets of clamping portions 31 for clamping, the two sets of clamping portions 31 are driven to move relative to each other on the slide rails 37, thereby driving the two sets of workpieces to move relative to each other until the welding positions of the two sets of workpieces abut, at which time the worker can weld, and if the height or angle of the welding table 23 needs to be adjusted during welding, the height and angle of the welding table 23 can be adjusted through the lifting assembly 2;

[0038] When the angle between certain workpieces needs to be welded, the support seat 32 can be driven to rotate by the driving device, and the angle between the two sets of workpieces can be adjusted through the reading scale 35 and the angle scale line 34, so that the angle meets the requirements;

[0039] As shown in Figures 3-4 The lifting assembly 4 is arranged on the equipment rack 22 and is used to temporarily place welding tools;

[0040] The lifting assembly 4 comprises a mounting frame 41 fixedly installed on one side of the equipment rack 22, a fixed rod 44 fixedly installed on the mounting frame 41, a straight rod 45 slidably arranged in the fixed rod 44 so as to extend out of or retract into the fixed rod 44, a circular rod rotatably installed in the straight rod 45, and a support frame 46 fixedly installed on the circular rod and comprising a lifting plate 42 fixedly installed thereon;

[0041] When the welding tools need to be temporarily placed, the straight rod 45 is pulled out, and the lifting plate 42 is rotated to drive the circular rod to rotate through the support frame 46, so that the lifting plate 42 is adjusted to a horizontal state;

[0042] Meanwhile, a threaded hole is formed in the support frame 46, and a screw 43 is threadedly installed in the threaded hole, so that the screw 43 can extend into the support frame 46 and abut against the circular rod when extending into the support frame 46, thereby fixing the circular rod and simultaneously fixing the lifting plate 42;

[0043] It should be noted that in the initial state, the straight rod 45 is retracted into the fixed rod 44, so that the lifting plate 42 is located on one side of the equipment rack 22 and is perpendicular to the base 1, thereby being stored;

[0044] In summary, during welding, when the welding tools need to be temporarily placed, the lifting plate 42 is pulled out, the straight rod 45 is extended out of the fixed rod 44 through the support frame 46, the lifting plate 42 is extended out of the equipment rack 22, and the welding table 23 is exposed, then the lifting plate 42 is rotated to drive the circular rod to rotate in the straight rod 45 until the lifting plate 42 is in a horizontal state, the screw 43 is screwed into the support frame 46 to fix the abutment of the circular rod, thereby simultaneously fixing the lifting plate 42, and then the welding tools to be placed can be placed on the lifting plate 42.
