DETAILED DESCRIPTION
[0021] To explain the technical content, objectives, and effects of the present invention in detail, the following embodiments are described in conjunction with the accompanying drawings. In the description of the embodiments, it should be understood that the terms indicating orientation or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the embodiments and simplify the description. They do not indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention.
[0022] like Figure 1 As shown, a coding device for an automobile rear torsion beam assembly according to a specific implementation method of the present scheme includes a stand 1, a coding host 2 arranged under the stand 1, and a tooling seat 3 arranged on the stand 1, characterized in that: the part of the stand 1 located at the bottom of the tooling seat 3 is set as a hollow area 4, and a screw motor 5 is also provided at the bottom of the stand 1, and the screw 6 of the screw motor 5 is arranged horizontally along the length direction of the stand 1, and a nut pair 7 that can move axially along the screw 6 is provided on the screw 6; a guide rail 8 parallel to the screw 6 is provided on the tooling seat 3, and a slider 9 is provided on the guide rail 8, and the slider 9 passes through the hollow area 4 through the connecting block 10 and is linked to the nut pair 7; a coding terminal 11 is installed on the slider 9, and the coding terminal 11 passes through the hollow area 4 and is connected to the coding host 2 through the material pipe 12; V-grooves for placing the rear torsion beam assembly 18 are provided on both sides of the tooling seat 3, so that the beam portion of the rear torsion beam assembly 18 is facing the coding terminal 11.
[0023] The working principle of this embodiment is:
[0024] When Figure 1 As shown, when the rear twist beam assembly 18 of the automobile needs to be coded, the parts are placed in the contoured V-grooves, and the workpieces are positioned by their own weight to achieve the same angle positioning of each workpiece. Figure 3 As shown, the cross section of the inkjet terminal 11 is 90° to the part coding area surface. Figure 2 As shown, screw 6 is driven by a Delta 1.5kW screw motor 5. Pressing the start button causes screw 6 to rotate forward, triggering the inkjet signal and driving inkjet terminal 11 to a preset position. Stable inkjet printing is performed along the way, and upon reaching the preset position, inkjet terminal 11 moves backward, returning to its starting point. If the part is removed without pressing the inkjet button, the device will sound an alarm.

[0027] Similarly, as a preferred technical solution of the embodiment, as shown in Figure 1 , 3 , the tool holder 3 includes two connected vertical beams 14, the horizontal beam 15 is arranged on the vertical beams 14 in the width direction of the rack 1, the trapezoidal positioning block 16 is arranged on the horizontal beam 15, the recess is formed between the trapezoidal positioning block 16 and the vertical beam 14, the detachable V-shaped block 17 is installed on the recess, and the V-shaped groove is formed. The detachable effect of the V-shaped block 17 also has the effect of being easy to replace, and has better adaptability.
[0028] Although the utility model has been described in detail in the above embodiment, some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the utility model all belong to the scope of protection required by the utility model.
