Description

Technical Field

[0001] The utility model relates to the technical field related to welding of a front bumper frame reinforcement plate assembly in vehicle production, in particular to a welding tool used for the bumper frame reinforcement plate assembly. Background Art

[0002] The total reinforcement plate assembly of the front bumper frame of an automobile is a welded part. The welding process of two parts is prone to dimensional errors, which directly leads to the assembly stability of the automobile production process. In order to ensure the welding of the two parts, the two welded parts are generally placed on the tooling for welding. When the welded parts on the existing market are welded on the welding tooling, since the welded parts are generally in large quantities after production, when the welded parts are placed on the tooling, the welded parts on the left and right sides are often placed upside down, which leads to welding errors during welding. After being discovered, it is necessary to clamp and replace them many times to correct the errors. As a result, the entire welding tooling often leads to frequent clamping and replacement of welded parts when welding welded parts, and errors will occur during later reassembly. Utility Model Content

[0027] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-6 The utility model provides a technical solution: a welding tool for a bumper frame reinforcement plate assembly, comprising a support base 1, which is arranged in a rectangular structure in a top view, and two casters are distributed at the bottom thereof, and the support base 1 is provided with two groups, and the two groups of support bases 1 are connected by a mounting plate 5;

[0029] The welding fixtures 2 are symmetrically arranged in two groups above the mounting plate 5, and each group is provided with two welding fixtures, and the bottoms of the two welding fixtures 2 are arranged in an "L"-shaped structure, and the bottoms of the welding fixtures 2 are installed with the mounting plate 5 by bolts;

[0030] Also includes;

[0031] Two welding assemblies 4 are provided, and the two are distributed on the left and right sides above the two sets of welding tools 2;

[0032] A welding mechanism 3, which is arranged between two welding fixtures 2, and is used to weld the welding assembly 4 arranged on the welding fixtures 2;

[0033] The welding assembly 4 and the welding fixture 2 are positioned by means of a latch positioning pin 6;

[0034] A positioning mechanism is also provided at the top of the welding tool 2, which includes a tool seat 21 and a tool positioning pin 211. The tool seat 21 is integrally installed at the top of the welding tool 2, and a tool positioning pin 211 is provided at the top of the welding tool.

[0035] The top of the tooling locating pin 211 is configured in a conical structure, and the bottom is configured in a polygonal structure when viewed from above. Two reserved grooves 7 are symmetrically arranged outside the polygonal structure, and a limiting component 8 is arranged inside the reserved groove 7.

[0036] When the welding assembly 4 is placed on the top of the tooling seat 21 , the through hole in the middle of the welding assembly 4 needs to be aligned with the through hole of the tooling seat 21 , and then the positioning work is performed through the latch positioning pin 6 .

[0037] When the welding assembly 4 is positioned with the top of the tooling seat 21, it is necessary to control the engagement between the perforation at the top of the welding assembly 4 and the tooling positioning pin 211 to complete the positioning work;

[0038] The use of latch locating pins and shape positioning can ensure assembly and prevent problems such as single parts being placed upside down or wrongly.

[0039] Further, according to Figure 5-6 As shown, the cross-section of the limit assembly 8 is arranged in a trapezoidal structure, and it includes a sliding rod 81, which slides in the slide groove inside the tooling positioning pin 211, and is connected to the slide groove through a shock absorbing spring 84;

[0040] The top end of the sliding rod 81 is connected to the rotating rod 82 via an axis, and the other end of the rotating rod 82 is also connected to the limiting rod 83 via an axis. Two rotating rods 82 are symmetrically arranged outside the limiting rod 83, and the limiting rod 83 is arranged vertically.

[0041] The inner side of the limit rod 83 is connected to the fixing seat inside the tooling positioning pin 211 through the telescopic cylinder 85;

[0042] In the present application, when the tooling locating pin 211 is engaged with the hole on the welding assembly 4, the telescopic cylinder 85 can be started to drive the limiting rod 83 at its top to move toward the hole wall direction of the welding assembly 4, and further the rotating rod 82 is rotated to drive the sliding rod 81 to move downward. When the sliding rod 81 moves, the vibration generated during the welding process of the entire welding assembly 4 can be weakened due to the presence of the shock-absorbing spring 84. When the limiting rod 83 and the hole wall are in contact with each other, the welding assembly 4 can be limited to ensure that it can be in a stable state during the welding process, thereby improving the welding quality.

[0043] When the welding assembly 4 is subsequently disassembled, the telescopic cylinder 85 can be controlled to drive the limiting rod 83 at its top to move in the opposite direction, so that the limiting rod 83 can be separated from the hole wall, making it easier to disassemble the welding assembly 4.

[0044] Working Principle: When using the welding tool for the bumper frame reinforcement plate assembly;

[0045] Step 1: First, install the left welding assembly 4 on the top of the left welding tool 2, and then adjust the position of the left welding assembly 4 on the tool seat 21. When adjusting, the two holes on the left welding assembly 4 need to correspond to the positions of the through holes on the tool seat 21 and the tool positioning pin 211, respectively, and press the left welding assembly 4 downward so that the inner hole and the tool positioning pin 211 are engaged with each other. After that, insert the pluggable plug positioning pin 6 between the outer hole and the hole on the tool seat 21 to complete the assembly work between the left welding assembly 4 and the left welding tool 2;

[0046] Step 2: Install the right welding assembly 4 above the right welding tool 2, and then adjust the position of the right welding assembly 4 on the tool seat 21. When adjusting, the two holes on the right welding assembly 4 need to correspond to the positions of the through holes on the tool seat 21 and the tool positioning pin 211, respectively, and press the right welding assembly 4 downward so that the inner hole and the tool positioning pin 211 are engaged with each other. After that, insert the pluggable plug positioning pin 6 between the outer hole and the hole on the tool seat 21 to complete the assembly work between the right welding assembly 4 and the right welding tool 2;

[0047] Step three: After the assembly is completed, the welding assemblies 4 on the left and right sides are welded using an external welding mechanism 3. In this application, the welding mechanism 3 is a suspended spot welding machine;

[0048] Step 5: After welding is completed, remove the latch positioning pins 6 on the left and right welding components 4, thereby completing a qualified frame assembly; the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0049] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
