[0042] To make the purpose, technical solutions and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the accompanying drawings.

[0043] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. The following will describe the present disclosure in detail with reference to the drawings and in combination with the embodiments.

[0044] In a vehicle, the vehicle body is often connected to the subframe through a fixed plate 200. As Figure 3 shown, the fixed plate 200 includes a flange edge 201 and a protrusion 202 protruding relative to the flange edge 201. The flange edge 201 semi-surrounds the protrusion 202, and the middle of the protrusion 202 has a through hole 2021. Among them, in combination with Figure 4 , Figure 5 shown, when the vehicle is assembled, the nut seat 300 will first pass through the through hole 2021 and be fixedly connected to the fixed plate 200 by a method such as but not limited to welding. After that, the fixed plate 200 will be bolted to the subframe, and the flange edge 201 will be welded to the vehicle body. After that, the screw will pass through the nut seat 300 to realize the fixed connection between the vehicle body and the chassis.

[0045] During the production process of the vehicle, the fixing plate 200 needs to be inspected before and after the nut seat 300 is sleeved on the fixing plate 200 to confirm whether the fixing plate 200 meets the usage standards.

[0046] In the related art, before the nut seat 300 is sleeved on the fixing plate 200, the flange edge 201 of the fixing plate 200 is used as the inspection reference. At this time, it is necessary to make the flange edge 201 of the fixing plate 200 fit with the inspection table, and there is a gap between the protruding part 202 of the fixing plate 200 and the inspection table; after the nut seat 300 is sleeved on the fixing plate 200, the nut seat 300 is used as the inspection reference. At this time, it is necessary to make the nut seat 300 fit with the inspection table, and there is a gap between the flange edge 201 and the inspection table. Therefore, before and after the nut seat 300 is sleeved on the fixing plate 200, two sets of inspection tables are required to make the flange edge 201 of the fixing plate 200 and the nut seat 300 fit with the inspection table respectively to realize the inspection of the fixing plate 200.

[0047] However, using two sets of inspection tables will increase the inspection cost.

[0048] To solve the above technical problems, an embodiment of the present disclosure provides an inspection table. As shown in Figure 1 、 Figure 2 and Figure 6 The inspection table includes a base 0, an inspection main body 1, a first positioning structure 2 and a second positioning structure 3. The inspection main body 1 is fixed to the base 0 and includes a connected first area 11 and a second area 12. The first area 11 semi - surrounds the second area 12. The first positioning structure 2 is detachably fixed to the first area 11 and is used to fit with the flange edge 201 of the fixing plate 200 to be inspected to support the flange edge 201, so that the protruding part 202 of the fixing plate 200 does not contact the second positioning structure 3. The second positioning structure 3 is fixed to the second area 12 and is lower than the first positioning structure 2. The second positioning structure 3 is used to fit with the side of the nut seat 300 away from the fixing plate 200 sleeved on the fixing plate 200 to support the nut seat 300 and make the flange edge 201 suspended.

[0049] In the embodiment of the present disclosure, the inspection table has a first state and a second state. The first state is the state where the first positioning structure 2 is fixed to the first area 11, and the second state is the state where the first positioning structure 2 is disassembled. In the first state, as shown in Figure 1 It is possible to inspect the fixing plate 200 that has not been assembled with the nut seat 300. Among them, the flange edge 201 of the fixing plate 200 can fit with the inspection table through the first positioning structure 2 to meet the inspection requirements; in the second state, as shown in Figure 6As shown, it is possible to detect the overall structure connected to the nut seat 300 and the fixing plate 200. Among them, the nut seat 300 can be fitted with the second positioning structure 3 to meet the detection requirements. Thus, by only installing or disassembling the first positioning structure 2, the state of the detection table can be switched to meet the detection requirements of the fixing plate 200 before and after the nut seat 300 is sleeved on the fixing plate 200, without the need to use two sets of detection tables, thereby reducing the detection cost.

[0050] Among them, the first region 11 is the region where the detection body 1 corresponds to the flange edge 201, and the second region 12 is the region where the detection body 1 corresponds to the nut seat 300 to be detected sleeved on the fixing plate 200.

[0051] Among them, before the nut seat 300 is sleeved on the fixing plate 200, the first positioning structure 2 can be installed on the first region 11. At this time, the flange edge 201 of the fixing plate 200 is in contact with the detection table through the first positioning structure 2. At the same time, there is a gap between the protruding portion 202 of the fixing plate 200 and the second positioning structure 3, so as to prevent the protruding portion 202 from directly contacting the second positioning structure 3 and interfering with the contact between the flange edge 201 and the first positioning structure 2, resulting in inaccurate detection results.

[0052] Among them, after the nut seat 300 is sleeved on the fixing plate 200, the first positioning structure 2 can be removed from the first region 11. At this time, the nut seat 300 can be in contact with the detection table through the second positioning structure 3. At the same time, there is a gap between the flange edge 201 of the fixing plate 200 and the detection body 1, so as to prevent the contact between the flange edge 201 and the detection body 1 from interfering with the contact between the nut seat 300 and the second positioning structure 3, resulting in inaccurate detection results.

[0053] Among them, as Figure 1 、 Figure 6 shown, when fixing the fixing plate 200, there is a gap between the edge of the fixing plate 200 and the detection body 1, and the size of this gap can be used as a standard for detecting whether the fixing plate 200 is deformed. Among them, when the fixing plate 200 meets the standard, the size of this gap is relatively uniform. When the size of this gap is within a certain range, it can be considered that the fixing plate 200 is qualified; otherwise, the fixing plate 200 is unqualified.

[0054] In the embodiment of the present disclosure, when detecting the fixing plate 200, it is mainly detected by a digital detection instrument to detect the sizes of the above-mentioned gaps and record them. The detection table mainly plays a role in fixing and positioning the fixing plate 200.

[0055] Among them, the second positioning structure 3 is in the shape of a circular open groove to fit with the nut of the nut seat 300.

[0056] As shown Figure 2 in FIG. 3, the middle part of the second positioning structure 3 has a detection hole 31, and the detection hole 31 is used to be opposite to the through hole 2021. The detection table further includes a detection pin 8, and the detection pin 8 includes a plugging part 81 and a flat plate structure 82. When the detection table is in the first state, the plugging part 81 is sequentially inserted into the through hole 2021 and the detection hole 31. After the plugging part 81 is inserted into the through hole 2021 and the detection hole 31, there is a gap between the flat plate structure 82 and the convex part 202, and this gap is used as a standard for evaluating whether the convex part 202 meets the requirements. If the convex part 202 is not deformed, the distances between the flat plate structure 82 and the convex part 202 at various places should be basically equal, and it can be at least controlled within a reasonable range. If the convex part 202 is deformed, the convex part 202 is locally warped or sunken, which will cause the distance between the locally warped or sunken part of the convex part 202 and the flat plate structure 82 to be too small or too large.

[0057] In this way, by detecting the gap between the flat plate structure 82 and the convex part 202, the flatness data of the convex part 202 can be obtained more conveniently.

[0058] In some embodiments, as Figure 1 shown in FIG. 4, the detection table further includes at least three reference blocks 9, and among them, at least three reference blocks 9 are non-collinear.

[0059] In this way, when the fixing plate 200 is placed on the detection table and the fixing plate 200 is detected, three non-collinear reference blocks 9 can be used as the reference of the detection table, and a coordinate system is established, so that the digital detection of the fixing plate 200 can be realized more quickly.

[0060] Optionally, the three non-collinear reference blocks 9 are located at the three top corners of the base 0.

[0061] In some embodiments, the first positioning structure 2 is a gasket.

[0062] In this way, by placing the gasket on the first area 11, the detection table can be switched to the first state, and by removing the gasket from the first area 11, the detection table can be switched to the second state. The placement and removal of the gasket are relatively fast and convenient. Therefore, the state of the detection table can be switched in a relatively convenient way, and thus the detection efficiency of the fixing plate 200 can be greatly improved.

[0063] Optionally, the gasket can be made of, for example but not limited to, rubber material.

[0064] In some embodiments, as Figure 1As shown, the inspection table includes a plurality of first positioning structures 2. The first positioning structure 2 is in the shape of a screw, which is inserted into the first area 11, and the nut is used to fit with the flange edge 201.

[0065] In this way, by inserting the screw-shaped first positioning structure 2 into the first area 11, the inspection table can be switched to the first state. By removing the screw-shaped first positioning structure 2 from the first area 11, the inspection table can be switched to the second state. And the placement and removal of the gasket are relatively fast and convenient. Thus, the state of the inspection table can be switched in a relatively convenient way, which can greatly improve the inspection efficiency of the fixing plate 200. Moreover, by inserting the first positioning structure 2 into the first area 11, the installation of the first positioning structure 2 can also be positioned, so as to prevent the first positioning structure 2 from shifting during the installation process, and further ensure that the fitting position of the contact surface between the first positioning structure 2 and the flange edge 201 remains unchanged to ensure the accuracy of the inspection of the fixing plate 200.

[0066] Optionally, the outer side of the first positioning structure 2 may or may not have a thread, and the embodiments of the present disclosure do not limit this.

[0067] In some embodiments, as Figure 1 As shown, the inspection table further includes a pressing block mechanism 4. The pressing block mechanism 4 includes a connected first fixing portion 41 and an extrusion portion 42. The first fixing portion 41 is fixed to the base 0, and the extrusion portion 42 is used to tightly press the flange edge 201 on the first positioning structure 2.

[0068] In this way, in the first state, after the flange edge 201 is fitted with the first positioning structure 2, through the extrusion portion 42 of the pressing block mechanism 4, the flange edge 201 can be tightly pressed on the first positioning structure 2, so that the position of the fixing plate 200 can be fixed by the extrusion portion 42, to prevent the fixing plate 200 from shifting when a relatively low external force is applied during the inspection of the fixing plate 200, so as to ensure the stable progress of the inspection of the fixing plate 200.

[0069] Optionally, the extrusion portion 42 may be, for example but not limited to, a pressing block made of rubber. Among them, the rubber material has good elasticity. Using a pressing block made of rubber to press the flange edge 201 can also prevent the flange edge 201 from deforming under the external force of the extrusion portion 42.

[0070] Optionally, the pressure of the extrusion portion 42 on the flange edge 201 is controlled at 4N - 6N. In this way, on the premise of ensuring the fixing effect of the extrusion portion 42 on the flange edge 201, it can prevent the extrusion force of the extrusion portion 42 on the flange edge 201 from being too large, resulting in deformation of the fixing plate 200.

[0071] In some embodiments, asFigure 1 As shown, the inspection table includes a plurality of pressing mechanisms 4, and the plurality of pressing mechanisms 4 are distributed around the inspection main body 1.

[0072] In this way, in the first state, after the flange edge 201 is fitted to the first positioning structure 2, through the pressing portions 42 of the plurality of pressing mechanisms 4, different positions of the flange edge 201 can be pressed along the circumferential direction of the second positioning structure 3 to ensure the effect of fixing the fixing plate 200, thereby further reducing the possibility of the fixing plate 200 shifting during the inspection of the fixing plate 200, and further ensuring that the inspection of the fixing plate 200 can be carried out stably.

[0073] Among them, in some embodiments, the inspection table includes a plurality of first positioning structures 2. The plurality of first positioning structures 2 are in the shape of screws. A part of the flange edge 201 will be fitted to the nuts of the first positioning structures 2, while other positions of the flange edge 201 will be suspended. The number of the pressing mechanisms 4 corresponds to the number of the first positioning structures 2. When the flange edge 201 is pressed by the pressing mechanisms 4, each pressing mechanism 4 is respectively pressed on the side of the flange edge 201 away from the first positioning structure 2, so that the first positioning structure 2 can support the pressing portions 42 of the pressing mechanisms 4 to prevent the flange edge 201 from being deformed when the pressing portions 42 press the flange edge 201.

[0074] Optionally, the first fixing portion 41 is integrally formed with the inspection main body 1.

[0075] In some embodiments, in combination with Figure 1 、 Figure 6 As shown, the pressing portions 42 of the pressing mechanisms 4 can move towards or away from the first positioning structure 2.

[0076] In this way, in the first state, before the flange edge 201 is fitted to the first positioning structure 2, the pressing portions 42 are moved away from the first positioning structure 2 to prevent the pressing portions 42 from hindering the fitting of the flange edge 201 of the fixing plate 200 to the first positioning structure 2; after the flange edge 201 is fitted to the first positioning structure 2, the pressing portions 42 are moved towards the first positioning structure 2 to press and fix the flange edge 201 of the fixing plate 200 through the pressing portions 42. In this way, by moving the pressing portions 42 towards or away from the first positioning structure 2, it is possible to ensure the fixing effect of the pressing portions 42 on the flange edge 201 while avoiding interference of the pressing portions 42 with the fitting of the flange edge 201 to the first positioning structure 2.

[0077] Among them, the briquetting mechanism 4 further includes a first locking tie rod 43 and a first rotating arm 44. One end of the first rotating arm 44 is hinged to the first fixing part 41, and the other end is connected to the extrusion part 42, so that the movement of the extrusion part 42 can be realized by the rotation of the first rotating arm 44. Among them, the first locking tie rod 43 is hinged to the first fixing part 41 and has a first locking state and a first relaxation state. When the first locking tie rod 43 is in the first locking state, a part of the first locking tie rod 43 abuts against the first rotating arm 44, so that the rotation of the first rotating arm 44 can be restricted. When the first locking tie rod 43 is in the first relaxation state, the first locking tie rod 43 releases the first rotating arm 44, and the first rotating arm 44 can rotate freely. Thus, when the extrusion part 42 extrudes the flange 201, the first rotating arm 44 can be locked by the first locking tie rod 43, so that the extrusion part 42 can be prevented from moving when being disturbed by an external force, and further the fixing effect of the extrusion part 42 on the flange 201 can be ensured.

[0078] Among them, in the second state, the extrusion part 42 of the briquetting mechanism 4 is located at a position away from the first positioning structure 2.

[0079] In some embodiments, as Figure 6 shown, the inspection table further includes a clamp mechanism 5. The clamp mechanism 5 includes a connected second fixing part 51 and a clamping part 52. The second fixing part 51 is fixed to the base 0, and the clamping part 52 is used to clamp the outside of the nut seat 300 to fix the nut seat 300.

[0080] In this way, in the second state, after the nut seat 300 is fitted with the second positioning structure 3, the nut seat 300 can be clamped by the clamping part 52 of the clamp mechanism 5 to fix the nut seat 300 on the second positioning structure 3, so that the position of the fixing plate 200 can be fixed by the clamping part 52, and when the fixing plate 200 is inspected, the fixing plate 200 can be prevented from shifting under the action of a relatively low external force, so that the inspection of the fixing plate 200 can be carried out stably.

[0081] Optionally, the clamping part 52 can be a clamp.

[0082] In some embodiments, the clamping part 52 can move towards or away from the nut seat 300.

[0083] Thus, in the second state, before the nut seat 300 is fitted to the second positioning structure 3, the clamping portion 52 is moved away from the second positioning structure 3 to prevent the clamping portion 52 from obstructing the fitting of the nut seat 300 of the fixing plate 200 to the second positioning structure 3; after the nut seat 300 is fitted to the second positioning structure 3, the clamping portion 52 is moved towards the second positioning structure 3 to clamp and fix the nut seat 300 of the fixing plate 200 through the clamping portion 52. Thus, by moving the clamping portion 52 towards or away from the second positioning structure 3, it is possible to ensure the fixing effect of the clamping portion 52 on the nut seat 300 while avoiding interference of the clamping portion 52 with the fitting of the nut seat 300 to the second positioning structure 3.

[0084] In the first state, the clamping portion 52 is located at a position away from the second positioning structure 3.

[0085] Wherein, the clamp mechanism 5 further includes a second locking rod 53 and a second rotating arm 54. One end of the second rotating arm 54 is hinged to the second fixing portion 51, and the other end is connected to the clamping portion 52, so that the movement of the clamping portion 52 can be realized by the rotation of the second rotating arm 54. Wherein, the second locking rod 53 is hinged to the second fixing portion 51 and has a second locking state and a second relaxation state. When the second locking rod 53 is in the second locking state, a part of the second locking rod 53 abuts against the second rotating arm 54, so that the rotation of the second rotating arm 54 can be restricted. When the second locking rod 53 is in the second relaxation state, the second locking rod 53 releases the second rotating arm 54, and the second rotating arm 54 can rotate freely. Thus, when the clamping portion 52 presses the nut seat 300, the second rotating arm 54 can be locked by the second locking rod 53, so that the movement of the clamping portion 52 caused by external force disturbance can be prevented, and further the fixing effect of the clamping portion 52 on the nut seat 300 can be ensured.

[0086] In some embodiments, in combination Figure 1 、 Figure 2 As shown, the first region 11 has a plurality of first positioning holes 111, and the plurality of first positioning holes 111 are used to face the second positioning holes 2011 on the flange edge 201 to position the flange edge 201.

[0087] Among them, in the first state, when detecting the fixing plate 200, it is often necessary to fix the fixing plate 200 at a unified position to facilitate the unified detection reference for the fixing plate 200. Therefore, in the embodiments of the present disclosure, when the flange edge 201 is attached to the first positioning structure 2, the second positioning hole 2011 on the flange edge 201 can be attached to the first positioning hole 111 on the detection body 1, and the positioning pin passes through the first positioning hole 111 and the second positioning hole 2011, so as to realize the positioning of the fixing plate 200 and facilitate the detection of the fixing plate 200.

[0088] In some embodiments, as Figure 1 shown, there is a gap between the edge of the flange edge 201 and the detection body 1. The inspection table further includes a go-no-go pin 6. The go-no-go pin 6 is detachably fixed to the base 0. The outer diameters of the first end 61 and the second end 62 of the go-no-go pin 6 are different, so as to judge whether the flatness of the flange edge 201 is qualified according to whether the first end 61 and the second end 62 can be inserted into the gap.

[0089] Among them, when the flange edge 201 is attached to the first positioning structure 2 and the nut seat 300 is attached to the second positioning structure 3, there is a gap between the edge of the flange edge 201 and the detection body 1. If the overall deformation of the flange edge 201 is within the required range, the distances between the edge of the flange edge 201 and the detection body 1 should be basically equal and can be controlled within a reasonable range. If the deformation of the flange edge 201 is large, the flange plate will be locally warped or sunken, which will cause the distance between the locally warped or sunken part of the flange edge 201 and the detection body 1 to be too small or too large.

[0090] In this way, when the end with a smaller outer diameter of the go-no-go pin 6 cannot enter any part of the gap between the edge of the flange plate and the detection body 1, it means that the gap between a certain part of the edge of the flange edge 201 and the detection body 1 is too small, and the flatness of the flange edge 201 is poor and does not meet the flatness requirements; when the end with a larger outer diameter of the go-no-go pin 6 can enter any part of the gap between the edge of the flange plate and the detection body 1, it means that the gap between a certain part of the edge of the flange edge 201 and the detection body 1 is too large, and the flatness of the flange edge 201 is poor and does not meet the flatness requirements. Thus, it is possible to initially judge whether the flatness of the flange edge 201 meets the standard through the go-no-go pin 6, so as to reduce the detection process of the fixing plate 200.

[0091] In addition, in the first state, the go-no-go pin 6 can also detect the distance between the flat plate structure 82 and the convex part 202 to initially judge whether the flatness of the convex part 202 meets the standard.

[0092] Exemplarily, the gauge between the edge of the flange 201 and the detection body 1 should be controlled at about 5 mm. For example, if it needs to be controlled within the range of [4.5 mm, 5.5 mm), the outer diameter of one end of the go-no-go pin 6 can be set to 4.5 mm, and the outer diameter of the other end can be set to 5.5 mm.

[0093] Among them, the detection table includes a plurality of go-no-go pins 6 with different specifications for use when the state of the detection table changes or the detection standard for the fixing plate 200 changes.

[0094] In some embodiments, as Figure 1 shown, the detection table further includes two handles 7 which are respectively fixed on opposite sides of the base 0.

[0095] In this way, through the handles 7, the detection table can be carried more conveniently, thereby improving the portability of the detection table.

[0096] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0097] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the present disclosure. At the same time, it should be understood that for the convenience of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0098] In the description of the present disclosure, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present disclosure and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present disclosure; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0099] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "above-mentioned", etc. can be used here to describe the spatial positional relationship of a device or feature shown in the drawings with other devices or features. It should be understood that the spatial relative terms are intended to cover different orientations in use or operation other than the orientation described in the drawings for the device. For example, if the device in the drawings is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0100] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without otherwise stating, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present disclosure.

[0101] The above are only the preferred embodiments of the present disclosure and are not used to limit the present disclosure. For those skilled in the art, the present disclosure can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.
