Description

Technical Field

[0001] This utility model belongs to the field of measurement technology, specifically relating to a tooling for measuring the inner gap of a body-in-white car door. Background Technology

[0002] In the process of automobile design and manufacturing, body-in-white is the welded assembly of body structural components and body panels, including the front fender, doors, engine hood, and trunk lid, but excluding accessories and decorative parts that have been welded but not yet painted.

[0003] The body-in-white internal clearance refers to the relative distance between the mounting surface and the compression surface of the rubber seal when the opening and closing parts are in the closed position in the body-in-white state (e.g., between the door and the body). It forms the basis for subsequent rubber seal assembly and is one of the key factors determining the overall vehicle sealing performance and door closing force. Controlling the body-in-white internal clearance is crucial for improving overall vehicle quality. However, due to various influencing factors and a lack of testing methods, internal clearance control has always been a difficult indicator to quantify.

[0004] In related technologies, there are two main methods for measuring the internal gaps of a body-in-white.

[0005] One method involves pressing clay (or modeling clay) between the car door and the side panel, and then measuring the height of the compressed clay at each point to define the standard body-in-white internal gap value.

[0006] The second method is manual measurement of the internal gap using a steel ruler or feeler gauge. This involves measuring the internal gap from inside the vehicle by hand after the door is closed.

[0007] The first measurement method has the following disadvantages and shortcomings:

[0008] Due to space constraints within the vehicle body, vertical readings are difficult, resulting in large measurement errors. Multiple re-measurements are required to obtain an accurate value for a specific point, leading to time-consuming and labor-intensive testing. Furthermore, the clay is compressed into shape after the car door is closed, and the height of the compressed area rebounds when the door is opened, causing a deviation from the actual gap values ​​within the vehicle body. In the white body state, the surface of the vehicle body has an oil layer adhering to it, making the clay prone to slipping and resulting in a high measurement failure rate.

[0009] The second measurement method has the following disadvantages and shortcomings:

[0010] The interior space of a car body-in-white is often limited. When measuring internal gaps in special locations and narrow spaces, manual measurement is often impossible. Traditional steel rulers and feeler gauges often have disadvantages such as difficulty in reading, poor measurement repeatability, and time-consuming and laborious measurement.

[0011] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0053] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0054] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0055] In some embodiments of this utility model, reference is made to Figures 1 to 10 A white body door inner gap measuring fixture 1, the whole is made of rigid material, such as all steel, including measuring fixture body 100 and sliding measuring component 200.

[0056] The measuring fixture body 100 has a through channel 110 and a mounting part. The mounting part is used to install the measuring fixture body 100 on the side door frame of the body-in-white when measuring the gap inside the door of the body-in-white, and then install the entire measuring fixture 1 on the side door frame of the body-in-white without hand measurement.

[0057] The sliding measuring element 200 is inserted into the channel 110 and slides in cooperation with the channel 110, meaning that under the action of external force, the sliding measuring element 200 can slide relative to the measuring fixture body 100 along the channel 110. The sliding measuring element 200 has a pushing end 210 exposed outside the channel 110; the sliding measuring element 200 is evenly provided with a number of length scale lines and scale values, collectively referred to as scales 220, and the direction of the length scale lines is parallel to the sliding direction of the sliding measuring element 200.

[0058] When the measuring fixture body 100 is installed on the side door frame of the body-in-white, that is, when the entire measuring fixture 1 is installed on the side door frame of the body-in-white, the sliding measuring component 200 is in the closing path of the body-in-white door, that is, when the body-in-white door is in the closing path, it can push the sliding measuring component 200 to slide along the channel 110.

[0059] The scale 220 on the sliding measuring component 200 can be formed by laser printing, which is clear and easy to read, and can still be readable after long-term use.

[0060] In some embodiments of this utility model, such as Figures 1 to 3 , Figure 5 As shown, the mounting part is a U-shaped slot 120 with the opening facing downwards, used to be clamped onto the four-door side frame 2, that is, the entire measuring fixture 1 is clamped onto the four-door side frame 2. The U-shaped slot 120 is a straight strip-shaped slot, and its extension direction, that is, its length direction, is perpendicular to the sliding direction of the sliding measuring component 200. The U-shaped slot 120 includes a horizontal top wall 121 and a first vertical side wall 122 and a second vertical side wall 123 arranged opposite to each other. The first vertical side wall 122 and the second vertical side wall 123 are located below the horizontal top wall 121, and their top ends are respectively connected to the two ends of the horizontal top wall 121. The first vertical side wall 122 is close to the pushing end 210 of the sliding measuring component 200, and the second vertical side wall 123 is away from the pushing end 210 of the sliding measuring component 200.

[0061] The sliding measuring component 200 is set horizontally, and the channel 110 is a corresponding horizontal channel 110. Of the two ends of the channel 110, the first end 111 is close to the pushing end 210 of the sliding measuring component 200, and the second end 112 is far away from the pushing end 210 of the sliding measuring component 200. The end face of the first end 111 of the channel 110 is a vertical surface, and the end face of the first end 111 of the channel 110 is coplanar with the first vertical sidewall 122 of the U-shaped slot 120.

[0062] The body-in-white door inner gap measuring fixture 1 in the above embodiment is suitable for measuring the inner gaps of the four doors of a body-in-white (usually referring to the two front doors and two rear doors of the body-in-white). Taking one of the four doors of the body-in-white as an example, the specific measurement process is as follows:

[0063] 1. Open the car door and attach the white body door inner gap measuring fixture 1 to the edge of the four-door side frame 2. The horizontal top wall 121 of the U-shaped groove 120 fits against the top surface 21 of the edge of the four-door side frame, and the first vertical side wall 122 of the U-shaped groove 120 fits against the outer vertical side 22 of the edge of the four-door side frame 2. The pushing end 210 of the sliding measuring component 200 is located on the outside of the four-door side frame 2, that is, on the side where the four doors are located.

[0064] 2. Pull the sliding measuring component 200 outwards from the channel 110 (the direction of movement of the sliding measuring component 200 is as follows) Figure 6 (As shown by arrow I) Sufficient scale 220 so that when the door is closed to a certain extent, the inner side of the door can contact the sliding measuring element 200, and push the sliding measuring element 200 inward (in the opposite direction of arrow I) during the continued closing process, that is, slide it closer to the side door frame 2 of the four doors;

[0065] 3. Close the car door until it is fully closed. At this point, the sliding measuring component 200 will stop moving inward.

[0066] 4. Open the car door and obtain the measurement value of the inner gap according to the scale value of the exposed channel 110 on the measuring sliding block.

[0067] For the four doors of the body-in-white, when the doors are fully closed, the distance between the inner side of the door and the outer vertical side 22 of the door frame 2 is the inner gap of the four doors. Since the first end 111 of the channel 110 is coplanar with the first vertical side wall 122 of the U-shaped slot 120, and the inner side of the door is in contact with the pushing end 210 of the sliding measuring component 200, the zero point of the scale value is set on the pushing end 210 of the sliding measuring component 200. The scale value gradually increases from the pushing end 210 to the other end of the sliding measuring component 200. When the doors are fully closed, the scale 220 exposed outside the slide rail on the sliding measuring component 200 is the measured value of the inner gap of the four doors, which can be read directly, further facilitating the measurement.

[0068] Following the above procedure, the internal clearances of the other doors in the four doors of the body-in-white can be measured sequentially.

[0069] In other embodiments of this utility model, such as Figures 7 to 10 As shown, the mounting part is also a U-shaped slot 120 with the opening facing downwards, used to be clamped onto the tailgate side frame 3, that is, the entire measuring fixture 1 is clamped onto the tailgate side frame 3. The U-shaped slot 120 is a straight strip-shaped slot, and its extension direction, that is, its length direction, is perpendicular to the sliding direction of the sliding measuring component 200; the U-shaped slot 120 includes a horizontal top wall 121 and a first vertical side wall 122 and a second vertical side wall 123 arranged opposite to each other, and the horizontal top wall 121 of the U-shaped slot 120 is close to the pushing end 210 of the sliding measuring component 200.

[0070] The sliding measuring component 200 is vertically arranged, and the channel 110 on the measuring fixture body 100 is a vertical channel 110. Of the two ends of the channel 110, the first end 111 (i.e., the upper end) is close to the pushing end 210 of the sliding measuring component 200, and the second end 112 (i.e., the lower end) is far away from the pushing end 210 of the sliding measuring component 200. The end face of the first end 111 of the channel 110 is a horizontal plane, and the end face of the first end 111 of the channel 110 is coplanar with the horizontal top wall 121 of the U-shaped groove 120.

[0071] The fixture 1 for measuring the inner gap of the body-in-white door in the above embodiment is suitable for measuring the inner gap of the tailgate (usually referring to the trunk door) of the body-in-white. The specific measurement process is as follows:

[0072] 1. Open the car door and attach the white body door inner gap measuring fixture 1 to the edge of the tailgate side door frame 3. The horizontal top wall 121 of the U-shaped groove 120 fits against the top surface 31 of the tailgate side door frame edge. The first vertical side wall 122 of the U-shaped groove 120 and / or the first vertical side wall 122 fits against the vertical side 32 of the tailgate side door frame 3 edge. The pushing end 210 of the sliding measuring component 200 is located above the tailgate side door frame 3, that is, on the side where the tailgate is located.

[0073] 2. Pull the sliding measuring component 200 outwards from the channel 110 (the direction of movement of the sliding measuring component 200 is as follows) Figure 10 (As indicated by the middle arrow J) Sufficient scale 220 so that when the door (tailgate) is closed to a certain extent, the inner side of the door can contact the sliding measuring element 200, and during the process of continuing to close the door, push the sliding measuring element 200 into the channel 110 (in the opposite direction of arrow J), that is, slide it towards the side door frame 3 of the tailgate.

[0074] 3. Close the car door until it is fully closed. At this point, the sliding measuring component 200 will stop moving inward.

[0075] 4. Open the car door and obtain the measurement value of the inner gap of the tailgate according to the scale value of the exposed channel 110 on the measuring sliding block.

[0076] For the tailgate of the white body, when the door is fully closed, the distance between the inner side of the door and the top surface 31 of the tailgate side frame edge is the inner gap of the tailgate. Since the end face of the first end 111 of the channel 110 is coplanar with the horizontal top wall 121 of the U-shaped slot 120, and the inner side of the door is in contact with the end face of the pushing end 210 of the sliding measuring component 200, the zero point of the scale value is still set on the end face of the pushing end 210 of the sliding measuring component 200. The scale value gradually increases from the pushing end 210 to the other end of the sliding measuring component 200. Therefore, when the door is fully closed, the scale exposed outside the slide rail on the sliding measuring component 200 is the measured value of the inner gap of the tailgate, which can be read directly, further facilitating the measurement.

[0077] When measuring the internal clearance of each door of the body-in-white, multiple internal clearance measuring fixtures 1 of the body-in-white doors described in the above embodiments can be installed around the side door frame at the same time. The internal clearance of all points of the door can be measured by opening and closing the door once, which greatly saves the time and labor cost of internal clearance measurement.

[0078] In some embodiments of this utility model, such as Figure 1 , Figure 3 , Figures 7 to 9 As shown, the push end 210 of the sliding measuring member 200 includes a smooth protrusion 211. This smooth protrusion 211 contacts the inner side of the car door, ensuring that when the inner side of the car door pushes the sliding measuring member 200 during the closing process, the inner side of the car door contacts and abuts against the smooth surface, preventing damage caused by the inner side of the car door abutting against the sharp parts of the sliding measuring member 200.

[0079] At this time, the zero point of the scale value on the sliding measuring component 200 is set on the smooth protrusion 211, and the gap between the four doors is expressed as follows: Figure 3 and Figure 6 The dimension L1 in the middle, the internal clearance of the tailgate is Figure 9 and Figure 10 The dimension L2 in the middle.

[0080] To improve the reliability of the body-in-white door inner gap measuring fixture 1 when it is mounted on the edge of the side door frame and to prevent it from loosening and affecting the measurement accuracy, the measuring fixture body 100 is provided with a locking component 300. When the U-shaped slot 120 is mounted on the side door frame, the measuring fixture body 100 is locked on the side door frame. This ensures that when the inner gap of the four doors is measured, the first vertical side wall 122 of the U-shaped slot 120 is tightly fitted against the outer vertical side 22 of the edge of the four door side door frame 2, and when the inner gap of the tailgate is measured, the horizontal top wall 121 of the U-shaped slot 120 is tightly fitted against the top surface 31 of the edge of the tailgate side door frame.

[0081] In some embodiments of this utility model, such as Figures 1 to 10 As shown, the locking component 300 is a locking bolt. By rotating the locking bolt, the inner clearance measuring fixture 1 is locked onto the four-door side frame 2 or the tailgate side frame 3.

[0082] The number of locking parts 300 can be one or two, such as... Figures 1 to 6 The four-door internal clearance measuring fixture 1 shown is small in size, and only one locking part 300 is required. The locking part 300 is located at the center of the extension direction of the U-shaped groove 120 so as to apply a balanced force to the measuring fixture body 100 when locking.

[0083] like Figures 7 to 10 The tailgate internal clearance measuring fixture 1 shown is slightly larger in size, with a longer U-shaped groove 120 and two locking parts 300. The two locking parts 300 are located at both ends of the extension direction of the U-shaped groove 120 to apply force evenly to the measuring fixture body 100 when locking.

[0084] The locking bolts ensure a secure hold, whether the car body is made of steel or aluminum.

[0085] Due to prolonged use, the sliding resistance between the sliding measuring element 200 and the channel 110 decreases, causing the sliding measuring element 200 to loosen and resulting in poor stability when sliding into position, thus affecting the accuracy of the reading. To solve this problem, in some embodiments of this utility model, a mounting hole 130 is formed on the inner wall of the channel 110, and an elastic element is installed in the mounting hole 130. The elastic element abuts against the sliding measuring element 200, and the direction of the force of the elastic element is perpendicular to the sliding direction of the sliding measuring element 200.

[0086] The elastic element can always provide a certain resistance to the sliding of the sliding measuring element 200. In the open to fully closed state, when the sliding measuring element 200 slides into place, it can also resist the sliding measuring element 200 through its elastic force, so that the sliding measuring element 200 is stably in the sliding position and ensures accurate reading of the inner gap.

[0087] The abutting end of the elastic element should be smooth, such as spherical or arc-shaped, to avoid scratching the sliding measuring element 200.

[0088] Furthermore, the mounting hole 130 is a through hole, with one end connected to the channel 110 and the other end penetrating the measuring fixture body 100; the elastic element is a spring plunger 140, with the ball end of the spring plunger 140 abutting against the sliding measuring element 200, such as... Figure 4 and Figure 8 As shown. By rotating the adjusting spring plunger 140 from the outer end of the mounting hole 130, the force exerted on the sliding measuring element 200 can be adjusted, thereby regulating and controlling the resistance and smoothness of the sliding measuring element 200 during its sliding process.

[0089] To facilitate the processing of the channel 110, in some embodiments of this utility model, the measuring fixture body 100 includes a first part 150 and a second part 160, the first part 150 and the second part 160 together form the channel 110, and the mounting part (i.e., the U-shaped slot 120) is located on the second part 160.

[0090] The first part 150 and the second part 160 can be connected as one unit by means of screw fastening or adhesive bonding, and no specific restrictions are imposed here.

[0091] The channel 110 has a rectangular cross-section, and the sliding measuring component 200 is a block with a rectangular cross-section, which facilitates processing and is conducive to sliding guidance and limiting.

[0092] Furthermore, the first part 150 and the second part 160 are provided with mutually cooperating positioning structures for positioning the first part 150 and the second part 160 during alignment, thereby improving the assembly efficiency and accuracy of the measuring fixture body 100.

[0093] The positioning structure can be a combination of positioning protrusions and positioning grooves, or other positioning structures, and no specific restrictions are imposed here.

[0094] like Figure 1 and Figure 6 As shown, the first part 150 can be a T-shaped block or an L-shaped block, and the second part 160 is correspondingly formed with a T-shaped clearance or an L-shaped clearance. The first part 150 and the second part 160 are directly inserted and spliced ​​to form a channel 110, which makes the entire measuring fixture 1 compact, small and portable.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
