Description

Technical Field

[0001] The embodiments of the present invention belong to the technical field of hole positioning, and more specifically, to a device and method for quickly positioning an invisible installation point inside an interior trim panel. Background Art

[0002] During the assembly of a complete vehicle, some interfaces are usually reserved on the body in white, and holes are opened at corresponding positions on the interior panels. After the assembly of the body in white and the interior panels is completed, the relevant functional components can be fixed in the reserved interfaces on the body in white through the holes on the interior panels to increase the fixing strength of the relevant functional components. If there is a positional offset between the opening of the interior panel and the corresponding reserved interface, that is, the reserved interface is not aligned, the relevant functional components cannot be assembled, and the body in white needs to be re-polished and the reserved interface needs to be made, which seriously affects the production progress and also has a certain impact on the strength of the body.

[0003] In order to avoid positional offset between the opening of the interior panel and the corresponding reserved interface, in the prior art, tooling dies are used for positioning of mass-produced models. With the assistance of the tooling dies, the opening of the interior panel and the reserved interface of the body-in-white can be positioned with high precision, guiding the opening of the interior panel at the designated location and the installation of the reserved interface of the body-in-white at the designated location, ensuring that the corresponding opening of the interior panel is aligned with the reserved interface of the body-in-white after assembly, and the positional offset is within the error range.

[0004] However, for models in the trial production stage, due to the small production batch, there is no tooling and die for positioning. The method of positioning and punching the interior panels on site is generally adopted, that is, after the interior panels are assembled, they are measured and positioned according to the marked positions on the drawings and then punched. Due to the immaturity of the sheet metal process and assembly process in the trial production stage, errors are prone to occur, especially when the reserved interface of the internal body-in-white cannot be seen after the interior panels are installed. It is very easy for the drilling position of the interior panels to deviate, so that the opening cannot be aligned with the reserved interface. In addition, for some curved parts, the measurement and positioning is more difficult, and the opening position offset will be greater. Summary of the invention

[0005] In view of the difficulty in measuring and locating the punching positions of various parts of the interior trim panel in the prior art, the present invention provides a device and method for quickly locating the invisible installation points inside the interior trim panel, which uses the magnetic field to make a preliminary judgment on the pre-opening area of ​​the interior trim panel and then accurately locates its center point. There is no need to measure and locate according to the drawings, and the operation is simple, accurate and efficient.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a quick positioning device for invisible installation points inside an interior trim panel, comprising: a magnet positioning quick-insert sleeve arranged on a reserved interface of a bracket, wherein an axially magnetized magnet is arranged inside the quick-insert sleeve, and the central axis of the magnet coincides with the central axis of the reserved interface of the bracket; a positioning box parallel to the interior trim panel, comprising an iron cutting encapsulation soft board arranged at the bottom and a side panel at the side, wherein the iron cutting encapsulation soft board is made of a flexible transparent material, wherein a cavity is arranged inside the quick-insert sleeve to encapsulate the iron cutting, and the side panel comprises a first side panel and a second side panel, wherein the first side panel and the second side panel are A side panel opening groove is opened at a corresponding position on the board; an identification layer is arranged at the bottom of the iron cutting package soft board; a movable base liner is sleeved on the positioning box to separate the identification layer from the interior panel; and a ball is slidably arranged on the top of the iron cutting package soft board; when in use, the positioning box is moved on the interior panel, and the area where the magnet is located is preliminarily determined by the iron cutting disturbance aggregation, and the ball is slid to above the iron cutting disturbance aggregation area, and the pre-opening center point of the interior panel is determined after it stops sliding, and the ball is pressed to force the iron cutting package soft board to deform downward, drive the identification layer to contact the interior panel, and mark the punching position on the interior panel.

[0007] Furthermore, a partition bar is provided in the iron-cut packaging flexible board to divide the cavity into a plurality of cavity areas.

[0008] Furthermore, the movable base substrate comprises an elastic hoop and a base substrate, the elastic hoop is arranged on both sides of the base substrate, and the width of the base substrate is consistent with the iron-cut packaging soft board.

[0009] Furthermore, when the ball contacts the iron-cut packaging soft board, the gravity exerted on the ball itself is smaller than the magnetic field force exerted on it by the magnet.

[0010] Preferably, the identification layer is made of a seal oil storage pad.

[0011] According to another aspect of the present invention, a method for quickly locating invisible installation points inside an interior trim panel is provided, comprising the following steps:

[0012] S1: Before assembling the interior trim panel, insert the magnet positioning quick-release sleeve into the reserved interface of the bracket of the body in white;

[0013] S2: Adjust the bending angle of the positioning box according to different parts of the interior panel to keep the iron-cut package soft board parallel to the surface of the interior panel;

[0014] S3: Move the positioning box, observe the gathering of iron cutting disturbances, and determine the area where the magnet is located;

[0015] S4: Place the ball bearing on the area where the iron cutting disturbance is concentrated, and accurately locate the position of the central axis of the reserved interface of the bracket after it stops sliding;

[0016] S5: Pressing the ball bearing forces the iron-cut package soft board to deform downward, driving the identification layer to contact the interior panel, and marking the punching position on the interior panel;

[0018] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0019] (1) The present invention provides a rapid positioning device for invisible installation points inside an interior trim panel. The device has iron chips encapsulated in an iron chip encapsulation soft board at the bottom of a positioning box. The iron chips cooperate with a magnet provided on a reserved interface of a bracket to quickly locate the area where a pre-opening of the interior trim panel is located. The center point of the pre-opening of the interior trim panel can be accurately located by the cooperation of a ball bearing and an axially magnetized magnet.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figure 1-4As shown, the present invention provides a quick positioning device for invisible mounting points inside an interior trim panel, comprising a magnet positioning quick-insertion sleeve 3, a positioning box 4, a ball 5, a movable bottom liner 6 and an identification layer 7, wherein the magnet positioning quick-insertion sleeve 3 is arranged on a reserved interface 11 of a bracket, and an axially magnetized magnet 31 is arranged therein; an iron cutting encapsulation soft board 41 is arranged at the bottom of the positioning box 4, which is made of a flexible transparent material, and the iron cutting 411 is encapsulated by a cavity arranged inside; the identification layer 7 is adhesively arranged at the bottom of the iron cutting encapsulation soft board 41, and its bottom The part is provided with a coating layer for marking the position; the movable bottom liner 6 is sleeved on the positioning box 4 to separate the identification layer 7 from the interior panel 2; when in use, the movable bottom liner 6 is moved flat against the interior panel 2, and the movement is stopped when the iron cuttings 411 are found to be disturbed and gathered, and the ball 5 is placed in the disturbed and gathered area of ​​the iron cuttings 411. When the ball 5 stops sliding, the ball 5 can be pressed to compress the iron cutting encapsulation soft board 41 to deform downward, so that the identification layer 7 contacts the interior panel 2 and leaves a mark with the coating, marking the punching position of the interior panel pre-opening 21. The rapid positioning device of the present invention uses a magnetic field to locate the punching position, and the overall device has a simple structure, low cost, easy use, high positioning accuracy, and can quickly find the center point of the interior panel pre-opening 21, thereby speeding up the production progress.

[0031] like Figure 2-4As shown, in the embodiment of the present invention, the positioning box 4 is a square open box, which includes an iron-cut encapsulated soft board 41 arranged at the bottom and a side panel 42 on the side. The iron-cut encapsulated soft board 41 is made of a flexible transparent material (such as PET, PC, PVC and other materials) and has a certain toughness. The iron-cut encapsulated soft board 41 may be deformed when subjected to a certain external pressure, and can return to its original state after the external pressure is removed. Further, a cavity is provided in the iron-cut encapsulated soft board 41, and an iron cut 411 is provided in the cavity. The iron cut 411 can move in the cavity and can produce a disturbance aggregation phenomenon under the traction of the magnetic field of the magnet 31. For example, when the magnetization direction of the magnet 31 is perpendicular to the iron-cut encapsulated soft board 41, the iron cut 411 gathers with the central axis of the magnet 31 as the base point, and the orientation of the magnet 31 can be quickly indicated; the iron-cut encapsulated soft board 41 is also provided with a partition bar 412, which divides the cavity into a plurality of cavity areas, and when the iron cut 411 is disturbed and gathered, the bottom magnet 31 can be quickly determined. At the same time, if multiple magnets 31 appear at the bottom of the same detection area, the separator 412 can prevent the first contacted magnet 31 from transferring most of the iron cuttings 411 into its magnetic field range, so that the later contacted magnet 31 cannot absorb enough iron cuttings 411 to indicate its position, especially when the iron cutting packaging soft board 41 is tilted or placed vertically to adapt to the inclined part or vertical part of the decorative panel 2 in the vehicle body, the iron cuttings 411 are gathered at the bottom of the decorative panel 2 when it is tilted or placed vertically under the action of gravity, and its effective detection area is greatly reduced, and even missed detection may occur. By providing the separator 412, the iron cuttings 411 are gathered on the separator 412 under the action of gravity, thereby increasing its detection area, and can effectively detect the magnet 31 placed at the bottom of the inclined part or vertical part of the interior panel 2, thereby avoiding the occurrence of missed detection. In the embodiment of the present invention, the side panel 42 can be conveniently held by the operator, and includes a first side panel 421 and a second side panel 422. The first side panel 421 and the second side panel 422 are provided with side panel opening grooves 43 at corresponding positions. The bottom of the side panel opening grooves 43 is flush with the top of the iron-cut packaging soft board 41. By providing the side panel opening grooves 43, the positioning box 4 can be conveniently bent along the bottom of the side panel opening grooves 43, so that the iron-cut packaging soft board 41 is kept parallel to the curved surface of the interior panel 2, so as to detect the magnet 31 provided at the bottom of the curved surface of the interior panel 2, so as to locate the approximate punching position of the interior panel pre-opening 21. In the embodiment of the present invention, by providing a flexible iron-cut packaging soft board 41 and a side panel opening groove 43 provided on the side panel 42, and adjusting its bending angle according to the external shape of the interior panel 2, the positioning box 4 is suitable for various complex curved surface environments in the vehicle body, and the punching position of the interior panel pre-opening 21 can be quickly located.

[0032] In the implementation of the present invention, the bottom of the iron-cut packaging soft board 41 is adhered with a marking layer 7, and the bottom of the iron-cut packaging soft board 41 is coated with pigment. After the positioning box 4 completes the positioning work, it can be pressed to force the iron-cut packaging soft board 41 to deform downward, driving the marking layer 7 to contact the interior panel 2, so that the pigment is applied to the interior panel 2, and the marking work of the positioning punching position is completed. The marking layer 7 can be made of a common seal oil storage pad on the market, which can be used repeatedly, and there is no need to prevent the pigment from drying up and repeating the coating work. After the positioning work is completed, it can be removed and stored, which is conducive to long-term use. In order to prevent the marking layer 7 from causing pollution to other parts of the interior panel 2 during movement, the positioning box 4 is provided with a movable bottom liner 6 to isolate the marking layer 7 from the interior panel 2. The movable bottom liner 6 includes an elastic hoop 61 and a bottom liner 62. The elastic hoop 61 is arranged on both sides of the bottom liner 62, and the width of the bottom liner 62 is consistent with that of the iron-cut packaging soft board 41. When in use, the base 62 is aligned and arranged at the bottom of the iron-cut packaging soft board 41, and the movable base 6 is fixedly sleeved on the positioning box 4 by utilizing the elastic deformation of the elastic hoop 61. The position of the movable base 6 can be changed on the positioning box 4 by pushing the elastic hoop 61 and the base 62. When the bending angle of the positioning box 4 is too large, it can be pushed to the curved surface of the interior trim panel 2, keeping the iron-cut packaging soft board 41 parallel to the curved surface, while effectively preventing the identification layer 7 from contaminating the interior trim panel 2.

[0033] In the implementation of the present invention, the magnet positioning quick-insertion sleeve 3 is arranged in the bracket reserved interface 11, the top is in contact with the bottom of the interior trim panel 2, the side thereof is provided with a thread matching the bracket reserved interface 11, and the top is provided with a notch, and the magnet positioning quick-insertion sleeve 3 can be quickly disassembled and assembled by a wrench matching the notch. The magnet 31 positioning quick-insertion sleeve 3 is also provided with an axially magnetized magnet 31 inside, and its central axis coincides with the central axis of the bracket reserved interface 11. In order to increase the magnetic force of the magnet 31, a rubidium magnet can be selected.

[0034] In order to further accurately locate the punching position on the interior panel, the embodiment of the present invention is provided with a ball 5, which can be placed in the disturbance gathering area of ​​the magnet 31 after the iron cutting 411 quickly completes the preliminary positioning of the magnet 31. Under the traction of the magnetic field force of the axially magnetized magnet 31, the ball 5 slides toward the central axis of the magnet 31. After being stable, the contact point between the ball 5 and the iron cutting package soft board 41 is located on the central axis of the magnet 31. By pressing the ball 5, the iron cutting package soft board 41 is forced to deform downward, driving the identification layer 7 to contact the interior panel 2, so that the identification point is located on the central axis of the magnet 31, and the precise positioning of the punching position on the interior panel is completed. When selecting the ball 5, the gravity it receives should be less than the magnetic field force it receives from the magnet 31, so as to avoid it falling due to the influence of gravity when locating the punching position on the top of the vehicle body and failing to accurately locate it.

[0035] As another aspect of the present invention, a method for quickly locating invisible installation points inside an interior trim panel is provided, comprising the following steps:

[0036] S1: Before assembling the interior trim panel 2, install the magnet positioning quick-insert sleeve 3 into the bracket reserved interface 11 of the body-in-white 1;

[0037] S2: Adjust the bending angle of the positioning box 4 according to different parts of the interior panel 2, so that the iron-cut package soft board 41 is parallel to the surface of the interior panel 2;

[0038] S3: Move the positioning box 4, observe the disturbance and aggregation of the iron cuttings 411, and determine the area where the magnet 31 is located;

[0039] S4: placing the ball 5 above the disturbance gathering area of ​​the iron cuttings 411, and accurately locating the position of the central axis of the bracket reserved interface 11 after the ball 5 stops sliding;

[0040] S5: Pressing the ball 5 forces the iron-cut package soft board 41 to deform downward, driving the marking layer 7 to contact the interior panel 2, marking the punching position on the interior panel 2;

[0041] S6: After the punching work is completed, the magnet positioning quick-insertion sleeve 3 is taken out using a wrench, and the next step of assembling related functional components is performed.

[0042] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
