Checking fixture for instrument panel cross beam

Abstract

The utility model relates to a gauge for an instrument panel cross beam. The gauge comprises a bottom plate; the inspection seat is arranged on the bottom plate, the side, away from the bottom plate, of the inspection seat is used for being matched with a to-be-inspected cross beam, a plurality of inspection hole sites are formed in the side, away from the bottom plate, of the inspection seat, and at least part of the inspection hole sites are used for being in one-to-one correspondence with a plurality of to-be-inspected holes of the to-be-inspected cross beam; and the inspection pin is used for sequentially penetrating through the inspection hole site and the to-be-inspected hole in a pluggable manner. As the inspection seat is set to be in a shape matched with the standard, whether the shape of the to-be-inspected cross beam is qualified or not can be intuitively judged by judging whether the inspection seat is matched with the to-be-inspected cross beam or not. The inspection seat is provided with a plurality of inspection hole sites matched with the standard parts, so that after the to-be-inspected cross beam is aligned with the inspection seat, whether the to-be-inspected holes in the to-be-inspected cross beam are qualified or not can be quickly judged by quickly inserting and pulling the inspection pins between the to-be-inspected holes and the inspection hole sites which correspond to each other; therefore, the inspection time is effectively reduced on the basis of ensuring the inspection precision, and the time cost of beam production is reduced.

Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle component inspection, and in particular to a testing fixture for a cross beam of an instrument panel. Background Art

[0002] Traditional instrument panel cross beams (CCBs) are made of a single material, often employing a complex welded tube and plate structure. This often leads to deformation after welding, which not only affects vehicle assembly and performance but can also reduce the load-bearing capacity of the instrument panel cross beam assembly, potentially causing accidents. Therefore, limiting and eliminating welding deformation during manufacturing is crucial. To this end, traditional all-metal CCBs are being replaced with partially plastic-coated steel. This hybrid steel-plastic instrument panel cross beam features a steel skeleton overmolded with plastic. The entire main beam is covered in plastic, resulting in performance comparable to traditional instrument panel cross beams. However, since this multi-material composite beam requires multiple layers of fabrication, its accuracy must be inspected before and after entering the injection molding machine. This inspection primarily focuses on the cross beam's alignment with the vehicle's bore. Existing inspection methods are time-consuming and prone to inaccurate inspections. Utility Model Content

[0003] The purpose of the present disclosure is to provide a checking fixture for a cross member of an instrument panel, so as to solve the problem of slow speed in precision inspection of the cross member of the instrument panel.

[0004] In order to achieve the above objectives, the present disclosure provides a gauge for an instrument panel crossbeam, comprising:

[0005] base plate;

[0006] An inspection seat is provided on the bottom plate, wherein a side of the inspection seat away from the bottom plate is used to cooperate with the beam to be inspected, and a plurality of inspection holes are provided on the side of the inspection seat away from the bottom plate, at least some of the inspection holes are used to correspond one-to-one with the plurality of inspection holes of the beam to be inspected; and

[0007] The inspection pin is used to be pluggable and pass through the inspection hole and the hole to be inspected in sequence.

[0008] Optionally, the inspection pin includes:

[0009] The first section is used to be inserted into the inspection hole and the hole to be inspected; and

[0010] The second section has a diameter greater than the diameter of the first section and the diameter of the inspection hole.

[0011] Optionally, the outer surface of the second section is covered with a rubber sleeve.

[0012] Optionally, a placement seat is further provided on the bottom plate, and a through hole cooperating with the inspection pin is opened on the placement seat, so that the inspection pin can be placed on the placement seat in a pluggable manner.

[0013] Optionally, there are a plurality of placement seats and they are arranged at intervals on the bottom plate, and there are a plurality of inspection pins and they correspond one-to-one to the placement seats.

[0014] Optionally, the edge of the inspection seat further includes a positioning hole, and the inspection tool further includes a positioning pin, which is used to pass through the beam to be inspected and cooperate with the positioning hole to limit the position of the beam to be inspected.

[0015] Optionally, the gauge further includes a limit assembly, and the limit assembly includes:

[0016] A base, disposed on the bottom plate and spaced apart from the inspection seat; and

[0017] The limiting claw has one end rotatably connected to the base and the other end is used to contact the beam to be inspected, and can press the beam to be inspected onto the inspection seat.

[0018] Optionally, an escape opening for evading the positioning pin is provided at one end of the limiting claw close to the beam to be inspected.

[0019] Optionally, the limiting component further includes:

[0020] A gripping member, one end of which is used for gripping, and the other end of which is formed with a U-shaped opening structure, wherein the end of the U-shaped opening structure is hinged to the base;

[0021] A connecting rod, one end of which is hinged on the limiting claw and the other end of which is hinged in the U-shaped opening structure, enables the limiting assembly to have:

[0022] In the compressed state, the connecting rod is located in the U-shaped opening structure and extends in the same direction as the U-shaped opening structure, and can limit the crossbeam to be inspected between the inspection seat and the limiting claw; and

[0023] In the open state, one end of the connecting rod hinged to the limiting claw extends out of the U-shaped opening structure, and the limiting claw can be spaced apart from the beam to be inspected.

[0024] Optionally, the base plate is made of metal, and the inspection seat is made of resin.

[0025] With the above technical solution, since the inspection seat is configured to match the standard shape, the conformity of the shape of the beam to be inspected can be intuitively determined by checking whether the inspection seat matches the beam to be inspected. The inspection seat is provided with multiple inspection holes that match the standard parts. Therefore, after the beam to be inspected is aligned with the inspection seat, the inspection pin can be quickly inserted and removed between the corresponding inspection holes to quickly determine whether the inspection holes on the beam to be inspected are conformable. This effectively reduces inspection time while ensuring inspection accuracy, reducing the time cost of beam production.

DETAILED DESCRIPTION

[0037] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0038] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" are defined relative to the orientation of the gauge during actual use, and directional terms such as "inner" and "outer" are defined relative to the outline of the corresponding component. Terms such as "first" and "second" are used to distinguish between different components and do not convey order or importance. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise indicated, identical reference numerals in different drawings represent identical or similar elements.

[0039] According to one embodiment of the present disclosure, Figures 1 to 7 As shown, a testing fixture for an instrument panel crossbeam may include a base plate 1, a test base 2, and a test pin 3. The test base 2 may be mounted on the base plate 1. The side of the test base 2 facing away from the base plate 1 is configured to engage the crossbeam 7 to be tested. The side of the test base 2 facing away from the base plate 1 is provided with a plurality of test holes 21, at least some of which correspond one-to-one with the plurality of test holes 71 in the crossbeam 7. The test pin 3 may be inserted and removed sequentially through the test holes 21 and the test holes 71.

[0040] With the above technical solution, since the inspection base 2 is configured to conform to the standard, the conformity of the shape of the beam 7 to be inspected can be intuitively determined by checking whether the inspection base 2 can fit the beam 7 to be inspected. The inspection base 2 is provided with multiple inspection holes 21 that conform to the standard. Therefore, after the beam 7 to be inspected is aligned with the inspection base 2, the inspection pin 3 can be quickly inserted and removed between the corresponding inspection hole 71 and the inspection hole 21 to quickly determine whether the inspection hole 71 on the beam 7 to be inspected is conformable. This effectively reduces inspection time while ensuring inspection accuracy, thereby reducing the time cost of beam production.

[0041] It should be noted that at least some of the inspection holes 21 are used to correspond one-to-one with the multiple inspection holes 71 of the beam 7 to be inspected. This means that a hole 71 to be inspected on one beam 7 to be inspected has a corresponding inspection hole 21 on the inspection seat 2, but an inspection hole 21 on the inspection seat 2 does not necessarily have a corresponding hole 71 to be inspected on the beam 7 to be inspected. Since there are too many holes on the beam 7 to be inspected, only some key holes are inspected. The selection of the holes 71 to be inspected can be set according to actual production needs. Therefore, the number and setting of the inspection holes 21 can correspond to all the holes on the standard part. In this way, when production needs change and the selection of the holes 71 to be inspected is different, the inspection holes 21 can also correspond, thereby adapting to the inspection of beams of the same shape but with different key hole positions, without the need to manufacture an additional inspection seat 2, thereby improving the versatility of the inspection seat 2.

[0042] Here, the base plate 1 can be made of metal, and the test base 2 can be made of resin. Resin can be more easily manufactured into different shapes, allowing for the production of different types of test bases 2 based on the shapes of the beams 7 to be inspected. Furthermore, the test base 2 can be configured to be removable from the base plate 1 to facilitate replacement of the base plate 1 or the test base 2, although this disclosure is not limited thereto.

[0043] Further, if Figure 1 、 Figure 2 and Figure 6 As shown, the inspection pin 3 may include a first section 31 and a second section 32. The first section 31 can be used to insert into the inspection hole 21 and the hole to be inspected 71, and the diameter of the second section 32 is larger than the diameter of the first section 31 and the diameter of the inspection hole 21. In this way, when the hole to be inspected 71 is not in the correct position, the first section 31 cannot pass through the hole to be inspected 71 and insert into the inspection hole 21 due to the misalignment between the hole to be inspected 71 and the inspection hole 21. When the diameter of the hole to be inspected 71 is too small, the first section 31 cannot pass through the hole to be inspected 71 and insert into the inspection hole 21. When the diameter of the hole to be inspected 71 is too large, although the first section 31 can pass through the hole to be inspected 71 and cooperate with the inspection hole 21, the second section 32 cannot press the beam to be inspected 7. When the hole to be inspected 71 of the beam to be inspected 7 is qualified, the first section 31 can pass through the hole to be inspected 71 and insert into the inspection hole 21, and the second section 32 can also press on the beam to be inspected 7. Here, a rubber sleeve 33 is also provided on the outer surface of the second section 32 to increase friction and facilitate taking.

[0044] According to one embodiment of the present disclosure, Figure 1 and Figure 5As shown, the bottom plate 1 may also be provided with a placement seat 4, which is provided with a through hole 41 that cooperates with the inspection pin 3, so that the inspection pin 3 can be plugged and removed from the placement seat 4. In this way, when the inspection pin 3 is not needed for inspection, the inspection pin 3 can be inserted into the through hole 41 to prevent it from being lost. When the inspection pin 3 is needed to inspect the hole 71 on the crossbeam 7 to be inspected, the inspection pin 3 only needs to be pulled out from the placement seat 4.

[0045] Furthermore, if Figure 1 As shown, the number of placement seats 4 can be multiple and spaced apart on the base plate 1, and the number of inspection pins 3 can also be multiple and correspond one to one with the placement seats 4. In this way, multiple inspection holes 71 on the inspection beam 7 can be inspected simultaneously. After inspecting one inspection hole 71, the inspection pin 3 remains inserted through the inspection hole 71 and inserted into the corresponding inspection hole position 21, thereby positioning the inspection beam 7 and reducing the possibility of displacement of the inspection beam 7 when inspecting multiple inspection holes 71.

[0046] According to one embodiment of the present disclosure, Figure 1 and Figure 2 As shown, the edge of the inspection seat 2 may also include a positioning hole 22, and the inspection tool also includes a positioning pin 5. The positioning pin 5 is used to pass through the beam 7 to be inspected and then cooperate with the positioning hole 22 to limit the position of the beam 7 to be inspected. Here, the positioning hole 22 and the positioning pin 5 are used to limit the position of the beam 7 to be inspected and the inspection seat 2 to improve the inspection accuracy. The positioning pin 5 can be set as a cylindrical structure so that the beam 7 to be inspected is limited to move only along the extension direction of the positioning pin 5. The positioning pin 5 can also be set as a stepped structure similar to the inspection pin 3, that is, there are two sections with different diameters. The end with a smaller diameter can be inserted into the positioning hole 22, and the end with a larger diameter can be pressed on the beam 7 to be inspected, so that the beam 7 to be inspected is fixed on the inspection seat 2. In addition, the number of positioning holes 22 can also be multiple, and they are located on both sides of the inspection seat 2. Multiple positioning holes 22 can be set at intervals on each side to improve the limiting effect of the beam 7 to be inspected.

[0047] Furthermore, if Figures 1 to 4As shown, the inspection tool can also include a limiting component 6, which includes a base 61 and a limiting claw 62. The base 61 can be set on the bottom plate 1 and spaced apart from the inspection seat 2. One end of the limiting claw 62 can be rotatably connected to the base 61, and the other end is used to contact the beam 7 to be inspected, so that the beam 7 to be inspected can be pressed on the inspection seat 2 to prevent the beam 7 to be inspected from shifting and improve the inspection accuracy. Regarding the connection method between the limiting claw 62 and the base 61, the limiting claw 62 can be directly hinged to the base 61 through a pin, and a torsion spring is provided on the pin, with the two ends respectively connecting the limiting claw 62 and the base 61 to ensure that in the absence of external force, the limiting claw 62 can provide a tendency to press toward the inspection seat 2, ensuring that the beam 7 to be inspected can be pressed on the inspection seat 2. When it is necessary to remove the beam 7 to be inspected, the beam 7 to be inspected can be taken out by simply bending up the limiting claw 62. The limiting claw 62 can also be connected to the base 61 through a rotating structure to achieve a rotational connection with the base 61. Specifically, the limiting assembly 6 can also include a gripping member 63 and a connecting rod 64. Among them, one end of the gripping member 63 can be used for gripping, and the other end can be formed with a U-shaped opening structure 631, and the end of the U-shaped opening structure 631 is hinged on the base 61. The gripping member 63 can be a multi-grooved structure to increase friction and facilitate the operator to hold it, which is not limited in this disclosure. One end of the connecting rod 64 can be hinged on the limiting claw 62, and the other end can be hinged in the U-shaped opening structure 631, which can enable the limiting assembly 6 to have a clamped state and an open state. In the clamped state, the connecting rod 64 is located in the U-shaped opening structure 631 and extends in the same direction as the U-shaped opening structure 631, which can limit the beam 7 to be inspected between the inspection seat 2 and the limiting claw 62 to ensure that the beam 7 to be inspected does not move during the inspection process. In the open state, the end of the connecting rod 64 hinged to the limiting claw 62 extends out of the U-shaped opening structure 631, and the limiting claw 62 can be spaced apart from the beam 7 to facilitate the operator to remove the beam 7 to be inspected.

[0048] In addition, if Figure 1 As shown, an end of the limiting claw 62 close to the beam 7 to be inspected may also be provided with an escape opening 621 for evading the positioning pin 5 to prevent interference with the positioning hole 22 .

[0049] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0051] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
