Technical Field

[0001] The utility model belongs to the technical field of railway line protection fence welding equipment, and in particular relates to a frame seam welding tool used for railway line protection fence. Background Art

[0002] The existing frame seam welding for railway line protection fences is done manually, which has the following defects:

[0003] 1. Manual work is used, the tooling is simple, the precision dimensions are poor, and the welding consistency cannot be guaranteed.

[0004] 2. It cannot be moved and can only be welded at a fixed point. The tooling can only be used for independent welding stations and cannot be used universally. Utility Model Content

[0005] The purpose of the utility model is to solve the deficiencies of the above-mentioned background technology and to provide a frame seam welding tool for railway line protection fences.

[0006] The technical solution adopted by the utility model is: a frame seam welding tool for railway line protection fence, including a welding positioning platform, a plurality of U-shaped frame mesh ear combined welding parts positioning fixtures arranged on the welding positioning platform, and a welding robot used for seam welding of the U-shaped frame after the outer frame of the angle steel is bent and welding the U-shaped frame to the front of the mesh ear, wherein the welding positioning platform forms a U-shaped structure.

[0007] In a further preferred structure, a plurality of positioning fixtures of the U-shaped frame mesh ear assembly welding parts are evenly spaced apart.

[0008] In a further preferred structure, the welding robot is slidably connected to a robot movable ground rail.

[0009] In a further preferred structure, the robot moving ground rail and the welding positioning platform form a U-shaped structure and two U-shaped sides are parallel.

[0010] In a further preferred structure, the distance between the two U-shaped sides of the U-shaped structure formed by the welding positioning platform is adjustable, so as to adapt to U-shaped frames of different sizes after the angle steel outer frame of the railway line protection fence is bent.

[0011] In a further preferred structure, the welding positioning platform includes two groups, which are respectively located at two ends of the robot's moving ground rail.

[0012] The utility model is used for the seam welding of the angle steel outer frame after bending of the railway line protection fence and for the automatic welding of the angle steel outer frame and the front side of the net ear.

[0013] The beneficial effects of the utility model are as follows:

[0014] (1) Accurate positioning and high part precision. During assembly, the positioning block is calibrated by the inspection fixture to ensure accurate fixation and ensure the consistency of product production welding.

[0015] (2) The positioning is firm and the quick clamp is configured. The product is clamped by the quick clamp, which is more reliable and stable than manual clamping during manual welding.

[0016] (3) After the positioning fixture is clamped, there is no need for continuous manual force, which is more labor-saving than manual welding, which requires constant pressing action. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In the figure, 1-welding positioning platform, 11-screw nut adjustment mechanism, 2-welding robot, 5-U-shaped frame mesh ear combination welding piece positioning fixture, 6-robot moving ground rail, a1-angle steel outer frame, b-mesh ear. DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not constitute a limitation on the present invention.

[0021] like Figure 1 As shown, the utility model includes a welding positioning platform 1, a plurality of U-shaped frame mesh ear combination welding piece positioning fixtures 5 arranged on the welding positioning platform 1, a welding robot 2 used for seam welding of the U-shaped frame after the outer frame a1 of the angle steel is bent and for welding the U-shaped frame to the front of the mesh ear b, and the welding positioning platform 1 is surrounded by a U-shaped structure.

[0022] The plurality of U-shaped frame mesh ear assembly welding piece positioning fixtures 5 are evenly spaced apart.

[0023] The welding robot 2 is slidably connected to the robot moving ground rail 6 .

[0024] The robot moving ground rail 6 and the welding positioning platform 1 form a U-shaped structure with two U-shaped sides parallel to each other.

[0025] The distance between the two U-shaped sides of the U-shaped structure formed by the welding positioning platform 1 is adjustable. Figure 2 As shown, the two U-shaped edges are driven by a screw nut adjustment mechanism 11 disposed at the bottom of the welding positioning platform 1 so that the distance between the two U-shaped edges can be adjusted to accommodate protective fences of different widths.

[0026] The welding positioning platform 1 includes two groups, which are respectively located at the two ends of the robot moving ground rail 6.

[0027] The working principle of the utility model is as follows: the U-shaped frame and the net ear b after the angle steel outer frame a1 is bent are manually placed in the U-shaped frame net ear combined welding piece positioning fixture 5 in sequence, the product positioning and clamping are completed, the loading action is completed, and then the welding robot 2 starts automatic welding, and the manual unloading is completed after the welding is completed. At this time, the angle steel outer frame a1 and the net ear b have been welded to form a U-shaped frame with net ear b combined welding piece.

[0028] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
