[0039] In this embodiment, the door cover 10 is accurately assembled to the fixing surface 101 of the tool body 100 through the first positioning component 200, and the connecting surface 102 of the tool body 100 is assembled to the measuring device or the matching sample frame 20 through the connecting component 300. In this way, the door cover 10 is fixed to the specified position of the measuring device or the matching sample frame 20 in the unified vehicle body simulation environment through the fixing tool 40, thereby ensuring the rapid matching and measurement of the door cover 10 and the vehicle body, improving the matching measurement efficiency, and reducing the cost; at the same time, compared with the traditional process of matching detection of four doors and two covers with the vehicle body, the present application does not need to use special inspection tools to perform matching analysis on different positions of the four doors and two covers with the vehicle body respectively, avoiding the problems of reference conversion and inevitable installation deformation between different inspection tools and the measuring device or the matching sample frame 20, thereby improving the accuracy and reliability of the measurement data and matching analysis data. In addition, the measurement data of the four doors and two covers and the matching analysis data with the simulated vehicle body can be used to predict in advance whether the appearance of the vehicle is qualified and whether local rectification and optimization are needed, which is conducive to improving the yield rate of the vehicle and reducing the production cost of the vehicle. It should be explained that the "door cover 10" in this application represents the "four doors and two covers" in the vehicle, namely the front left door, front right door, rear left door, rear right door, front cover, and rear tail cover.

[0040] Specifically, the fixing tool 40 is configured as a combination component including at least a tool body 100, a first positioning assembly 200 and a connecting assembly 300. The tool body 100 can be a rectangular frame, which can be formed by connecting four columns end to end. The four columns can be connected and fastened by fasteners such as screws / bolts, or by welding, mortise and tenon joints, etc. The first positioning assembly 200 is configured as a combination component including at least a positioning member 210, a first limiting member 220 and a first fixing member 230. The positioning member 210 can be approximately an inverted Z-shaped columnar structure, and its top end is used to be inserted into the positioning hole of the vehicle door cover 10 to limit the vehicle door cover 10 on the plane where its panel is located, so as to prevent the vehicle door cover 10 from shaking or shifting on the plane where its panel is located; the first limiting member 220 can be an L-shaped columnar structure, which is arranged close to the positioning member 210 and is used to abut against the inner side of the vehicle door cover 10 to prevent the vehicle door cover 10 from continuing to approach the tool. The main body 100; the first fixing member 230 can be approximately an L-shaped hook structure, which is arranged close to the positioning member 210, and is used to hook the inner hole on the door cover 10 when the positioning hole on the door cover 10 is sleeved on the positioning member 210 and the inner side of the door cover 10 abuts against the first limiting member 220, so as to achieve the connection and fastening of the door cover 10 and prevent the door cover 10 from being separated from the tooling main body 100; the first fixing member 230 can cooperate with the first limiting member 220 to prevent the door cover 10 from moving in its installation direction, thereby improving the connection and fastening between the door cover 10 and the tooling main body 100. The connecting component 300 is arranged on the connecting surface 102 of the tool body 100, and is used to assemble the tool body 100 and the door cover 10 fixed on the tool body 100 at the specified position of the measuring device or the matching sample frame 20. In this way, the measurement of the door cover 10's own data and the matching analysis of the door cover 10 and the body can be realized in a unified body simulation environment, avoiding the problems of reference conversion and inevitable installation deformation between four doors and two covers and different special gauges, different special gauges and the measuring device or the matching sample frame 20 in the traditional matching measurement operation, thereby improving the accuracy and reliability of the measurement data and matching analysis data.

[0041] In one example, two or more groups of first positioning components 200 can be provided, and the two groups of first positioning components 200 can be symmetrically arranged at the corners of the fixed surface 101 of the tooling body 100, or the multiple groups of first positioning components 200 can be force-balancedly arranged on the fixed surface 101 of the tooling body 100 to form a symmetrical and uniform force system on the tooling body 100, thereby avoiding uneven force on the vehicle door cover 10 and improving the connection stability and reliability between the vehicle door cover 10 and the tooling body 100.

[0042] In one example, the connection components 300 can be set to two or more groups. The two groups of connection components 300 can be symmetrically arranged at the corners of the connection surface 102 of the tooling body 100, or the multiple groups of connection components 300 can be force-balancedly arranged on the connection surface 102 of the tooling body 100 to form a symmetrical and uniform force system on the tooling body 100, avoid uneven force on the tooling body 100, and improve the connection stability and reliability between the tooling body 100 and the measuring device or the matching sample rack 20.

[0043] In a possible implementation, the first fixing member 230 includes an elastic portion (not shown in the figure) and a hook portion 231 , and the hook portion 231 is telescopically connected to the tool body 100 via the elastic portion.

[0044] In this embodiment, the specific configuration of the first fixing member 230 is optimized. Specifically, the first fixing member 230 is configured as a combined component including at least an elastic portion and a hook portion 231. The elastic portion may be a spring, which is configured between the hook portion 231 and the tooling body 100, and is used to provide elastic force to the hook portion 231 and provide a movable space for the hook portion 231; the hook portion 231 may be a J-shaped hook structure, and the curved hook thereon is a free end, which is used to cooperate with the inner hole on the door cover 10. In this way, when the door cover 10 abuts against the positioning hole on the door cover 10 which is sleeved on the positioning member 210 and the inner side of the door cover 10 abuts against the first limit member 220, the hook portion 231 is pulled to overcome the elastic force on the elastic portion so that the curved hook on the hook portion 231 hooks the inner hole on the door cover 10, thereby realizing the connection and fastening between the fixing tool 40 and the door cover 10. At this time, the hook portion 231 is subjected to the elastic force pulled back by the elastic portion, and the curved hook hooking the door cover 10 provides a force pressing the door cover 10 toward the tooling body 100, thereby firmly connecting the door cover 10 to the tooling body 100.

[0045] It should be understood that the direction of the hook on the hook portion 231 can be freely selected according to the position of the inner hole on the door cover 10, and the direction of the hook on the hook portion 231 is not limited here.

[0046] In a possible implementation, the first positioning assembly 200 further includes a first integrated component 240 , and the positioning component 210 , the first limiting component 220 , and the first fixing component 230 are connected to the fixing surface 101 of the tool body 100 via the first integrated component 240 .

[0047] In this embodiment, the specific configuration of the first positioning component 200 is further optimized. Specifically, the first positioning component 200 is configured as a composite component that at least includes a positioning member 210, a first limiting member 220, a first fixing member 230 and a first integrated member 240. The first integrated member 240 can be a rectangular plate-like structure, which can be connected and fastened to the fixing surface 101 of the tooling body 100 by fasteners such as screws / bolts. The positioning member 210, the first limiting member 220 and the first fixing member 230 can be connected and fastened to the first integrated member 240 by fasteners such as screws / bolts, or can be connected to the first integrated member 240 by welding / bonding and the like. In this way, the integration of the positioning member 210, the first limiting member 220 and the first fixing member 230 can be achieved through the first integrated member 240, thereby improving the structural compactness of the first positioning component 200.

[0048] In a possible embodiment, the positioning member 210 includes a support column 211, a limiting column 212 and a plug-in column 213 which are arranged in sequence, the support column 211 is arranged on the first integrated component 240, the limiting column 212 extends in a direction parallel to the fixing surface 101, and the plug-in column 213 and the support column 211 both extend in a direction perpendicular to the fixing surface 101.

[0049] In this embodiment, the specific configuration of the positioning member 210 is optimized. Specifically, the positioning member 210 is configured as a composite member including at least a support column 211, a limiting column 212 and a plug-in column 213. The support column 211 can be an L-shaped square column, whose short side can be welded on the first integrated component 240, and whose long side is perpendicular to the plate surface of the first integrated component 240; the limiting column 212 can be a trapezoidal block or an L-shaped block structure, which is horizontally placed on the top of the long side of the support column 211 to form an angle with the support column 211, and the angle can be 90°. In this way, a limiting surface can be formed on the top of the limiting column 212 to abut against the inner side wall of the vehicle door cover 10, which can prevent the vehicle door cover 10 from continuing to move toward the tooling body 100, and can cooperate with the plug-in column 213 to achieve positioning and limiting of the vehicle door cover 10; the plug-in column 213 can be a cylinder with a smooth outer surface to reduce friction with the vehicle door cover 10 and improve mechanical protection of the vehicle door cover 10.

[0050] In one example, the plug post 213 is wrapped with a buffer layer on the outside, and the limiting post 212 is provided with a buffer layer at least on its top to prevent the door cover 10 from directly contacting the positioning member 210 and causing damage. The buffer layer can be foam, flexible soft glue / rubber, etc., and is not limited here.

[0051] In one example, a connecting column can be added between the support column 211 and the limiting column 212, and the top surface of the connecting column, the top surface of the support column 211 and the top surface of the limiting column 212 are flush with each other. In this way, the contact area between the positioning member 210 and the vehicle door cover 10 is increased, thereby improving the positioning stability of the positioning member 210 and the vehicle door cover 10.

[0052] In a possible embodiment, the first limiting member 220 includes a connecting portion 221, a supporting portion 222 and an abutting portion 223 which are arranged in sequence, the supporting portion 222 is connected to the first integrated component 240 through the connecting portion 221, and the abutting portion 223 is arranged at one end of the supporting portion 222 away from the first integrated component 240.

[0053] In this embodiment, the specific configuration of the first position-limiting member 220 is optimized. Specifically, the first position-limiting member 220 is configured as a composite member including at least a connecting portion 221, a supporting portion 222 and an abutting portion 223. The connecting portion 221 may be a plate-like structure, which may be connected and fastened to the outer edge of the first integrated member 240 by fasteners such as screws / bolts; the supporting portion 222 may be a square column, which may be vertically connected to the connecting portion 221, and the supporting portion 222 may partially or completely extend out of the first integrated member 240 to increase the support of the fixing fixture 40 to the vehicle door cover 10. The force area makes the supporting force on the vehicle door cover 10 distributed over a larger area, thereby improving the force stability of the vehicle door cover 10; the abutting portion 223 can be a cylinder, which is arranged at the middle position of the top end of the supporting portion 222 and extends in the same direction as the supporting portion 222. The size of the abutting portion 223 is smaller than that of the supporting portion 222, so as to form a limit on the vehicle door cover 10 on the top surface of the supporting portion 222, thereby preventing the vehicle door cover 10 from passing through the supporting portion 222 and abutting on the tooling body 100, thereby improving the mechanical protection of the vehicle door cover 10.

[0054] In one example, the outer side of the abutment portion 223 is wrapped with a buffer layer, and the support portion 222 is provided with a buffer layer at least on its top to prevent the door cover 10 from directly contacting the positioning member 210 and causing damage. The buffer layer can be foam, flexible soft glue / rubber, etc., and is not limited here.

[0055] In a possible implementation, the connection assembly 300 includes a connection member 310 and a first fastener 320 . The connection member 310 is connected to the connection surface 102 of the tool body 100 . The first fastener 320 is movably plugged into the connection member 310 to lock the connection member 310 with the measuring device or match the sample rack 20 .

[0056] In this embodiment, the specific configuration of the connection component 300 is optimized. Specifically, the connection component 300 is configured as a combined component including at least a connection member 310 and a first fastener 320. The connection member 310 may be a plate-like structure, which may be connected and fastened to the connection surface 102 of the tooling body 100 by fasteners such as screws / bolts. Its shape may be rectangular, triangular, trapezoidal, circular or other shapes, and the operator may select any shape according to actual needs; the first fastener 320 may be a long screw / long bolt, etc., which may be movably configured on the inner area of ​​the connection member 310. In this way, the first fastener 320 may pass through the connection hole on the connection member 310 and be inserted into the fastening hole on the measuring device or the matching sample frame 20, so as to realize the connection and fastening of the fixed tooling 40 with the measuring device or the matching sample frame 20, thereby realizing the accurate detection of the data of the door cover 10 itself or the matching analysis data between the door cover 10 and the simulated body, and improving the aesthetics and reliability of the appearance of the whole vehicle.

[0057] In a possible implementation, the tool body 100 is provided with an avoidance window 103 and a plurality of weight-reducing holes 104.
