The lower end of the detection rod 26 is threadedly connected to the ball head 28.

[0027] The description of the front, back, left, and right positions is based on the tooling and inspection fixture in use. Left and right correspond to the two sides of the length direction of the fixture base plate 1, and front and back correspond to the two sides of the width direction of the fixture base plate 1.

[0028] First, place the left front lower control arm welding assembly onto the triangular hole plate 6, socket 13, left support 2, and right support 4. The positioning protrusions 5 on the upper ends of the left support 2 and right support 4 are respectively engaged in the corresponding positioning holes 33 to achieve positioning of the left front lower control arm welding assembly. Then, multiple clamping devices 8 press down on the upper end of the left front lower control arm welding assembly to achieve fixation. The three detection holes on the upper end of the triangular hole plate 6 are aligned with the three mounting holes 35 on one end of the lower control arm plate 36, and the first detection pins 7 are inserted. If all three first detection pins 7 can be inserted, the hole positions of the three mounting holes 35 are qualified; otherwise, if any one first detection pin 7 cannot be inserted, it is unqualified. Then, hold the handle part 12 and control the sleeve insertion post 11 to slide to the right. If the sleeve insertion post 11 can be inserted into the inner hole 31 of the mating sleeve 30, then the mating sleeve 30... If the inner hole 31 is qualified, then it is unqualified; otherwise, it is unqualified. Hold the handle part 24 and insert the positioning pin 23 at the lower end of the large hole detection pin 14 into the socket 13. If the large hole detection pin 14 can be inserted into the installation large hole 34, then the installation large hole 34 is qualified; otherwise, it is unqualified. Next, hold the ball head 28 and control the detection rod 26 to slide upward. If the detection pin 27 at the upper end of the detection rod 26 can be inserted into the center hole 37, then the center hole 37 is qualified; otherwise, it is unqualified. Finally, flip the rocker arm 16 over, align the through hole in the middle of the rocker arm 16 with the pin 19 and insert the pin 19 so that the top plate 17 remains stationary. If both second detection pins 18 can be inserted into the upper hole 32, then both upper holes 32 are qualified; otherwise, if even one second detection pin 18 cannot be inserted, it is unqualified. All of them must be qualified for the left front lower control arm welding assembly to be considered a qualified product.

[0029] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0030] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0031] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0032] The above provides a detailed description of a welding fixture for the left front lower control arm provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
