Description

Technical Field

[0001] The utility model belongs to the field of measuring equipment and relates to a device for measuring the installation fit of a sound insulation piece. Background Art

[0002] Hot-pressed parts are formed by hot pressing. During the hot pressing process, the material will be compressed and shrunk. After being taken out of the hot pressing mold, the material will have a certain degree of rebound deformation. When the degree of rebound at different positions is different, the product will warp. Due to the differences in the incoming raw materials, in the actual production process, there will be inconsistent warping of each part after hot pressing. Especially for hot-pressed parts with larger sizes, the consistency of product warping is worse after hot pressing. When the warping of the hot-pressed parts exceeds a certain value, the hot-pressed parts will be installed on the sheet metal parts of the car, resulting in poor fit between the two. This not only affects the sound insulation effect of the sound insulation parts, but also causes the rivets to be subjected to tension. After continuous force, the rivets are easily broken, which seriously affects the fixing reliability and service life of the rivets. Therefore, before the sound insulation parts leave the factory, their installation fit needs to be measured.

[0003] At present, a vernier caliper is usually used to measure the installation fit of the sound insulation component, specifically using the rivet installation holes on the sound insulation component for measurement. This measurement method has the following problems: 1. Low measurement efficiency; 2. The measurement environment is not the actual installation condition, and the test data is inaccurate. Summary of the invention

[0009] Furthermore, it also includes a driving mechanism, through which the detection unit and the bracket are controlled to rotate.

[0010] Furthermore, the second surface is provided with a mounting groove, the standard plate is fixed in the mounting groove, a through hole penetrating the first surface and the second surface is fixed in the mounting groove, and the push rod passes through the through hole to contact the sound insulation component.

[0011] Furthermore, the standard plate is provided with a positioning ring, the positioning ring is coaxial with the through hole, and the positioning ring is connected to the push rod.

[0012] Furthermore, the sound insulation member is fitted with the first surface, the position of the push rod on the standard plate is the upper scale line, and when the distance between the sound insulation member and the first surface is a set value, the position of the push rod on the standard plate is the lower scale line.

[0013] Furthermore, the detection state of the sound insulation member includes a first detection state and a second detection state. The first detection state is the installation fit when the sound insulation member is located above the first surface.

[0017] 2) The utility model pushes the push rod to contact the sound insulation member to obtain the positional relationship between the end and the standard scale, and observes whether the end of the push rod is within the standard scale to confirm whether the spacing between the sound insulation member and the automobile sheet metal mounting surface is qualified.

DETAILED DESCRIPTION

[0027] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0028] Example:

[0029] like Figure 1-Figure 6 As shown, a device for measuring the installation fit of a sound insulation piece includes a detection unit 1, the detection unit 1 includes a test bench 11 and a plurality of measuring tools 12, the test bench 11 includes a first surface 111 and a second surface 112, the sound insulation piece is installed on the first surface 111, the measuring tool 12 is installed on the second surface 112, and the distance between the sound insulation piece and the first surface 111 is detected by the measuring tool 12.

[0030] The first surface 111 and the second surface 112 are located on opposite sides of the test bench 11. For example, the first surface 111 is the upper end surface of the test bench 11, and the second surface 112 is the lower end surface of the test bench 11, or the first surface 111 is the lower end surface of the test bench 11, and the second surface 112 is the upper end surface of the test bench 11. Through this arrangement, the measuring tool 12 and the sound insulation component are respectively located on both sides of the test bench 11 to measure the distance between the sound insulation component and the first surface 111.

[0031] Preferably, the first surface 111 is the inner concave surface of the test bench 11. To facilitate the installation of the sound insulation component, the outer contour of the first surface 111 matches the outer contour of the sound insulation component. During installation, the sound insulation component is installed on the first surface 111, and the outer contour of the sound insulation component is located within the outer contour of the first surface 111 to achieve the positioning installation of the sound insulation component, thereby improving the installation efficiency and installation accuracy of the sound insulation component.

[0032] The first surface 111 is adapted to the sheet metal mounting surface on the automobile, that is, the first surface 111 simulates the sheet metal mounting surface on the automobile. When the sound insulation component is fixedly installed on the first surface 111, this embodiment detects the distance between the sound insulation component and the first surface 111 by the measuring tool 12, which is equivalent to detecting the distance between the sound insulation component and the sheet metal mounting surface of the automobile, thereby simulating the measurement environment to a real installation condition, making the detection data more accurate.

[0033] A plurality of measuring tools 12 are respectively installed at different positions of the second surface 112 of the test bench 11, and are used to detect the distance between the sound insulation component and different positions of the first surface 111. According to production experience, the installation position of the measuring tool 12 can generally be selected as the position where the gap between the sound insulation component and the automobile sheet metal mounting surface is the largest. The installation position and installation quantity of the measuring tool 12 are set according to actual needs, and this embodiment does not limit this.

[0034] The measuring tool 12 is used to detect the distance between the sound insulation component and the first surface 111. The distance shows the installation fit between the sound insulation component and the first surface 111, that is, the installation fit between the sound insulation component and the automobile sheet metal installation surface. The smaller the distance, the better the installation fit.

[0035] The measuring tool 12 includes a push rod 121 and a standard plate 122. The standard plate 122 is fixed on the second surface 112. The standard plate 122 is provided with a standard scale 1221. The push rod 121 is movably connected to the standard plate 122. The push rod 121 slides and contacts the sound insulation component. The distance between the sound insulation component and the first surface 111 is confirmed by the sliding distance of the push rod 121 and the standard scale 1221.

[0036] The second surface 112 is provided with a concave installation groove 1121, and the standard plate 122 is fixed in the installation groove 1121. A through hole 1122 penetrating the first surface 111 and the second surface 112 is fixed in the installation groove 1121. The push rod 121 passes through the through hole 1122, and its contact end contacts the sound insulation component.

[0037] The standard plate 122 includes a first fixed plate (not shown) connected to the mounting groove 1121 and a second fixed plate (not shown) provided with a standard scale 1221. The push rod 121 is movably connected to the second fixed plate, and the first fixed plate and the second fixed plate form an L-shaped structure.

[0038] Preferably, the standard plate 122 is provided with a positioning ring (not shown in the figure), which is coaxial with the through hole 1122. The push rod 121 passes through the positioning ring and the through hole 1122 and contacts the sound insulation component. The positioning ring is used to limit the moving direction of the push rod 121 to prevent the push rod 121 from becoming eccentric during movement, resulting in inaccurate detection.

[0039] The two ends of the push rod 121 are set as a contact end and a terminal end. The contact end passes through the through hole 1122 and is used to abut against the sound insulation member. The terminal end faces the second fixed plate. The push rod 121 is pushed to contact the sound insulation member to obtain the positional relationship between the terminal end and the standard scale 1221. The terminal end is observed to be within the standard scale 1221 to confirm whether the spacing between the sound insulation member and the automobile sheet metal mounting surface is qualified. When the terminal end is within the standard scale 1221, it is considered that the spacing between the sound insulation member and the automobile sheet metal mounting surface is qualified. When the terminal end is not within the standard scale 1221, it is considered that the spacing between the sound insulation member and the automobile sheet metal mounting surface is unqualified. In this embodiment, whether the spacing between the sound insulation member and the automobile sheet metal mounting surface is qualified by intuitively observing whether the terminal end of the push rod 121 is within the standard scale 1221. Compared with the existing method of measuring with a vernier caliper and confirming whether the spacing between the sound insulation member and the automobile sheet metal mounting surface is qualified by reading data, the operation of this application is simpler and the detection efficiency is higher.

[0040] The standard scale 1221 includes an upper scale line and a lower scale line, and the upper scale line and the lower scale line are scale lines on both sides of the standard scale 1221. Figure 6 The a shown is the upper scale line. Figure 6 The b shown is the lower scale line, and the distance between the upper scale line and the lower scale line is a set value, which is the allowable spacing between the sound insulation component and the automobile sheet metal mounting surface. When the push rod 121 slides between the upper scale line and the lower scale line during the process of abutting against the sound insulation component, it is considered that the installation fit between the sound insulation component and the automobile sheet metal mounting surface detected by the measuring tool 12 is qualified.

[0041] In this embodiment, when the sound insulation member is completely in contact with the first surface, the position of the end of the push rod 121 at the standard plate 122 is the upper scale line, and when the distance between the sound insulation member and the first surface is a set value, the position of the end of the push rod 121 at the standard plate 122 is the lower scale line, and the area between the upper scale line and the lower scale line is the standard scale.

[0042] Preferably, the set value is 3 mm.

[0043] The push rod 121 is movably connected to the standard plate 122. In this embodiment, the push rod 121 and the standard plate 122 are independent structures. When it is necessary to detect the installation fit of the sound insulation component, the push rod 122 is passed through the positioning ring and the through hole 1122 to contact the sound insulation component for detection. After the detection is completed, the push rod 122 is removed and stored for standby use, or cooperated with the standard plate 122 of the next measuring tool 12 to detect the installation fit of another position of the sound insulation component. In other embodiments, the push rod 121 can be connected to the standard plate 122 structure, that is, the push rod 121 is connected to the positioning ring, for example, by a spring or other elastic structure. During non-detection time, the push rod 122 and the standard plate 122 remain in a relatively static state. At this time, the contact end of the push rod 122 passes through the through hole 1122 and is flush with the first surface. During the detection time, the push rod 122 is pushed to contact the isolation component for detection. After the detection is completed, the external force is removed, and the push rod 122 is reset under the action of the elastic force, waiting for the next sound insulation component to be detected.

[0044] The measuring device also includes a bracket 2, and the detection unit 1 is installed on the bracket 2, that is, the bracket 2 carries the detection unit 1, and the detection personnel places the detection unit 1 on the bracket 2, and then performs the detection operation of the installation fit of the sound insulation component.

[0045] Preferably, the detection unit 1 is mounted on the bracket 2 and the two are rotatably connected. During the detection operation of the installation fit of the sound insulation component, the detection unit 1 can be rotated relative to the bracket 2, thereby realizing the detection of the installation fit of the sound insulation component in two states.

[0046] The above two states include a first detection state and a second detection state. The first detection state is the installation fit when the sound insulation component is located above the first surface. In this state, the gravity direction of the sound insulation component is toward the first surface. The second detection state is that after the test bench 11 is reversed 180 degrees, the sound insulation component is located below the first surface, and the gravity direction of the sound insulation component is toward the ground. Through the rotational connection between the detection unit 1 and the bracket 2, the installation fit of the sound insulation component in the two states is detected, which simulates two common working conditions under the actual loading state, and effectively improves the accuracy of the detection.

[0047] like Figure 1 As shown, the bracket 2 includes a load-bearing platform 21 and a fixing frame 22. The detection unit 1 is installed on the load-bearing platform 21 and is rotatably connected to the load-bearing platform 21. The load-bearing platform 21 is installed on the fixing frame 22 and the two are connected by a lifting mechanism. The lifting mechanism is used to realize the lifting and lowering of the load-bearing platform 21 in the height direction to adapt to the use of detection personnel of different heights and the requirements of different working conditions.

[0048] Preferably, four wheels are provided at the bottom of the bracket 2 to facilitate the movement of the measuring device.

[0049] Preferably, the measuring device further comprises a driving mechanism 3 , through which the detection unit 1 is rotatably connected to the bracket 2 .

[0050] The driving mechanism 3 can realize the rotation of the detection unit 1 relative to the bracket 2 automatically or manually. The driving mechanism 3 can be set as a rotating motor to realize automatic driving of the detection unit 1 to rotate. The rotating motor is fixed on the bracket 2, and the power output shaft of the rotating motor is connected to the test bench 11. The rotating motor is started to drive the test bench 11 to rotate; or the driving mechanism 3 is set as a handle, the detection unit 1 and the bracket 2 are rotatably connected through a rotating shaft, the handle is connected to the end of the rotating shaft, and the handle is rotated to drive the rotating shaft to rotate and then rotate the detection unit 1.

[0051] The measuring device also includes a suspension device 4, which is fixed to the fixing frame 22 of the bracket 2 and is opposite to the test bench 11. When the detection unit 1 is in the second detection state, the detection unit 1 is suspended and connected to the suspension device 4 to ensure that the detection unit 1 will not fall during the detection process, thereby improving the safety of the detection.

[0052] The measuring device further includes a tool box 5, which is disposed on the bracket 2. In this embodiment, the tool box 5 is located at the bottom of the bracket 2 and is used to place small tools used in conjunction with the measuring device, such as wrenches, rivets, push rods, and other components. Preferably, the tool box 5 is detachably disposed at the bottom of the bracket 2.

[0053] The detection process of the measuring device is as follows: control the detection unit 1 to be in the first detection state, place the sound insulation piece on the first surface 111 and fix it with fasteners such as rivets, push the push rod 121 to make its contact end contact with the sound insulation piece, and observe whether the end of the push rod 121 is within the standard scale 1221. If not, it is considered that the sound insulation piece is unqualified. If so, it is considered that the spacing between the sound insulation piece at this position and the automobile sheet metal mounting surface is qualified, and other detection positions of the sound insulation piece are continuously detected. After all the detection positions are qualified in the first detection state, the driving mechanism 3 drives the detection unit 1 to flip 180 degrees to put it in the second detection state, and the detection unit 1 is suspended and connected with the suspension device 4. The detection operation is continued in this state. Only when the installation fit of the sound insulation piece at different detection positions in the first detection state and the second detection state is qualified, the sound insulation piece is considered qualified and meets the design requirements.

[0054] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
