Description

Technical Field

[0001] The utility model relates to the field of automobile inspection tooling, in particular to a frameless front door inspection tooling. Background Art

[0002] Some cars use frameless doors, which are generally assembled to the welded white body through large external tooling. For example, a frameless door adjustment system for assembling frameless doors is proposed in a Chinese patent application with application number CN202310340225.0.

[0003] When the rear door of the car adopts a frameless door, the Z-direction position of the front of the rear door can be determined by using the installation and adjustment detection tooling that simulates the B-pillar outer panel, and the Z-direction position of the rear of the rear door can be determined by matching the side of the body with the rear of the rear door.

[0004] When the front door of the car is a frameless door, the Z-direction position of the rear of the front door can be determined by using the assembly and adjustment test tooling that simulates the B-pillar outer panel. However, since there is no point in the front of the front door that directly matches the Z-direction of the body side, it is impossible to directly detect the Z-direction position of the front of the front door through the body side.

[0005] Therefore, the Z-position of the front part of the frameless front door is basically fine-tuned by the door installers based on their experience. Due to the different proficiency and experience of different door installers, the accuracy and consistency of the Z-position of the front part of the frameless front door cannot be guaranteed. The front part of the frameless front door is prone to appearance and interior DTS problems. It is difficult to ensure the product quality in terms of alignment of the frameless front door ribs, alignment of the instrument panel and the frameless front door interior panel, and alignment of the fender trim and the frameless front door guard plate. It is difficult to ensure the exquisiteness of the car, which is very likely to cause user complaints. In addition, after the car is transferred to the final assembly process, in order to avoid rust, the position of the frameless front door hinge will basically not be changed. When there is an appearance problem caused by the Z-position of the frameless front door, there is basically no rework solution, and batch rework is even more difficult. Utility Model Content

In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0027] like Figure 1 and Figure 2 As shown, this embodiment proposes a frameless front door detection tooling, the upper part of the frameless front door detection tooling is provided with multiple positioning surfaces 104 and multiple positioning pins 2, the multiple positioning surfaces 104 are used to fit with the surface on the automobile A-pillar 5, and the multiple positioning pins 2 are used to respectively cooperate with the multiple holes on the automobile A-pillar 5; the lower part of the frameless front door detection tooling is provided with a detection reference part 102 which serves as a detection reference for detecting the Z-direction position of the frameless front door 4.

[0028] By adopting the above-mentioned technical solution, by arranging multiple positioning surfaces 104 and multiple positioning pins 2 on the upper part of the frameless front door detection tooling, the frameless front door detection tooling can be positioned and installed on the A-pillar 5 of the automobile using the multiple positioning surfaces 104 and the multiple positioning pins 2, and then the Z-axis position of the frameless front door 4 is detected using the detection reference part 102, thereby providing an easy-to-operate detection solution, which helps to reduce the difficulty of ensuring the Z-axis position of the front part of the frameless front door 4.

[0029] The above-mentioned frameless front door inspection tool can be used in a welding workshop to detect the Z-direction position of the front part of the frameless front door 4, and can be used to prevent, investigate and analyze assembly problems at the frameless front door 4, greatly reducing the difficulty of preventing, investigating and analyzing assembly problems at the frameless front door 4.

[0030] In some embodiments, the plurality of positioning pins 2 are used to respectively cooperate with the plurality of decorative strip mounting holes on the automobile A-pillar 5. With the above technical solution, the plurality of decorative strip mounting holes on the automobile A-pillar 5 are used to position the frameless front door detection tooling, which has the characteristic of being easy to implement.

[0031] In some embodiments, the frameless front door inspection tool comprises an arm 101 and a plurality of bosses protruding from the arm 101, and a plurality of positioning surfaces 104 are respectively arranged on the surfaces of the plurality of bosses. By adopting the above technical solution, the positioning surfaces 104 are arranged on the surfaces of the bosses, which can reduce the difficulty of matching the plurality of positioning surfaces 104 with the surfaces on the A-pillar 5 of the automobile, and helps to reduce the difficulty of operating the frameless front door inspection tool.

[0032] In some embodiments, the detection reference portion 102 is fixedly connected to the lower end of the arm-shaped portion 101, and the detection reference portion 102 gradually bends downward and extends from the inside of the vehicle to the outside of the vehicle. The lower end of the detection reference portion 102 is provided with a detection reference surface 103, and the detection reference surface 103 serves as a detection reference for detecting the Z-direction position of the upper edge 401 of the window sill of the frameless front door 4. By adopting the above technical solution, by reasonably setting the structure of the detection reference portion 102, the gap between the detection reference surface 103 and the upper edge 401 of the window sill of the frameless front door 4 can be intuitively measured. As a specific example, the detection reference surface 103 simulates the contour of the Z-direction edging of the front window sill area of ​​the frameless front door 4. In order to facilitate the disassembly and assembly of the frameless front door detection tooling, a 5mm gap is reserved between the detection reference surface 103 and the Z-direction edging of the front window sill area of ​​the frameless front door 4.

[0033] In some embodiments, a hollow structure is provided on the arm portion 101 and / or the detection reference portion 102. By adopting the above technical solution, the hollow structure can reduce the weight of the frameless front door detection tooling, which helps to reduce the difficulty of operating the frameless front door detection tooling.

[0034] As a specific example, the frameless front door detection tool comprises an integrally formed tool body 1, and the arm portion 101 and the detection reference portion 102 are both part of the tool body 1. In order to reduce the weight of the frameless front door detection tool, the tool body 1 can be made of aluminum alloy.

[0035] In some embodiments, the arm-shaped portion 101 includes a gripping section 105 for the user to hold, and the cross-sectional area of ​​the gripping section 105 gradually decreases from both ends to the middle. By adopting the above technical solution, a gripping section 105 with a cross-sectional area gradually decreasing from both ends to the middle is provided, which is convenient for the user to hold and operate the frameless front door detection tooling, and is conducive to reducing the difficulty of operating the frameless front door detection tooling. As a specific example, the side of the gripping section 105 is set to a curved surface 106 that is gradually concave from both ends to the middle, and the corner of the gripping section 105 is set to a chamfer 107 that is gradually concave from both ends to the middle, so that the cross-sectional area of ​​the gripping section 105 can be gradually reduced from both ends to the middle.

[0036] In some embodiments, two bosses are provided on the arm 101, and in the length direction of the arm 101, the two bosses are respectively located on both sides of the gripping section 105. By adopting the above technical solution and reasonably setting the arrangement positions of the bosses and the gripping section 105, a larger gap can be formed between the gripping section 105 and the A-pillar 5 of the automobile, thereby further reducing the difficulty of operating the frameless front door detection tooling.

[0037] In some embodiments, the upper portion of the frameless front door detection tooling is provided with a magnetic attraction portion for magnetically adsorbing on the A-pillar 5 of the automobile. With the above technical solution, the magnetic attraction portion is provided to adsorb and connect the frameless front door detection tooling to the A-pillar 5 of the automobile, thereby reducing the difficulty of operating the frameless front door detection tooling. As a specific example, a plurality of positioning surfaces 104 are embedded with magnet blocks 3 for magnetically adsorbing on the A-pillar 5 of the automobile, and a plurality of magnet blocks 3 constitute a plurality of magnetic attraction portions. In a specific implementation, an embedding groove may be provided on the positioning surface 104, and the magnet block 3 is embedded in the embedding groove.

[0038] In some embodiments, two positioning pins 2 are provided on the upper part of the frameless front door detection tooling, one positioning pin 2 is a round pin, and the other positioning pin 2 is a diamond pin. The round pin is the main positioning pin, which is used to limit two degrees of freedom; the diamond pin is the secondary positioning pin, which is used to limit one degree of freedom. The positioning is performed by the combination of the round pin and the diamond pin, which has the characteristic of facilitating the installation of the frameless front door detection tooling on the vehicle body. In the specific implementation, the two positioning pins 2 are fixedly connected to the two positioning surfaces 104 respectively.

[0039] like Figure 3 and Figure 4As shown, the working process of the above-mentioned frameless front door detection tool is as follows: the user holds the grip section 105, and inserts the two positioning pins 2 into the two decorative strip mounting holes on the car A-pillar 5 respectively, and the magnet block 3 adsorbs the car A-pillar 5 so that the positioning surface 104 is attached to the car A-pillar 5. The frameless front door 4 is closed naturally, and then the Z-direction gap value between the detection reference surface 103 and the upper edge 401 of the window sill of the frameless front door 4 is measured, and the measured gap value minus 5mm is the Z-direction deviation value of the front part of the frameless front door 4. The Z direction refers to the vehicle height direction of the car.
