[0002] like Figure 1 As shown, in the existing traditional electric vehicle bottom tube inspection fixture, two blocks 3 are welded on the bottom plate 1 according to the designed length of the bottom tube 2. The two blocks 3 are respectively used to support the two ends of the bottom tube 2 in the length direction. A plurality of support blocks 4 are also arranged between the two blocks 3 to support the position between the two ends of the bottom tube 2. In practical applications, the inspection fixture cavity is processed by a CNC milling machine, and the finished bottom tube of the electric vehicle is placed in the inspection fixture cavity. The length of the bottom tube is checked by the length of the inspection fixture cavity. In the above-mentioned electric vehicle bottom tube inspection fixture, since the spacing between the two blocks 3 is fixed, the length of the inspection fixture cavity is fixed, and the inspection fixture is in a fixed form. This fixed inspection fixture has the following problems:

[0003] There is uncertainty in the length and specifications of the bottom tube material. When the length of the bottom tube 2 is changed, the length of the inspection fixture cavity also needs to be changed accordingly. Fixed inspection fixtures can only be one-to-one for different models, and cannot be universal for multiple models. Therefore, it is necessary to change the inspection fixture or design different bottom tube inspection fixtures for different models of bottom tubes 2. The change of inspection fixtures requires increased costs of repeated consumption of personnel and materials; designing different bottom tube inspection fixtures will lead to an increase in the number of inspection fixtures, which not only increases the difficulty and cost of storage and maintenance of the inspection fixtures, and increases the workload of employees, but also because the electric vehicle market is iterative and updated quickly, the inspection fixtures are limited by the scope of application, have a short service life, and cannot be reused. Designing too many inspection fixtures will undoubtedly cause a waste of resources. Utility Model Content

[0030] One of the purposes of the utility model is to provide an adjustable bottom tube inspection fixture for electric vehicles, which can adapt to the bottom tube length inspection of different models to solve the problems of poor versatility, short service life, high consumption cost, waste of resources, etc. of existing fixed inspection fixtures.

[0031] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Embodiment 1

[0033] The present embodiment provides an adjustable inspection fixture 100 for bottom tubes of electric vehicles, comprising a bottom plate 1, a first baffle 5, a second baffle 6 and a size reading device 7, wherein the first baffle 5 and the second baffle 6 are both arranged on the bottom plate 1, and the bottom tube 2 to be inspected is placed between the first baffle 5 and the second baffle 6, and the first baffle 5 and the second baffle 6 are respectively used to support the two ends of the bottom tube 2, and a inspection fixture cavity for placing the bottom tube 2 is formed between the first baffle 5 and the second baffle 6 (the molding method of the inspection fixture cavity is the same as the molding method of the inspection fixture cavity of the existing fixed inspection fixture, which will not be repeated here), wherein at least one of the first baffle 5 and the second baffle 6 is movably connected to the bottom plate 1, so that the spacing between the first baffle 5 and the second baffle 6 is adjustable, thereby making the length of the inspection fixture cavity adjustable, thereby realizing the inspection of bottom tubes 2 of different lengths. The size reading device 7 has a length scale for displaying the spacing between the first baffle 5 and the second baffle 6. The above-mentioned electric vehicle bottom tube adjustable inspection fixture 100, by movably connecting at least one of the first baffle plate 5 and the second baffle plate 6 to the bottom plate 1, can make the distance between the first baffle plate 5 and the second baffle plate 6 adjustable, so that the length of the inspection fixture cavity is adjustable, and then it is possible to detect bottom tubes 2 of different lengths in different models, and has a wide range of applications and can be used repeatedly, thereby solving the problems of poor versatility, short service life, high consumption cost, and waste of resources existing in existing fixed inspection fixtures.

[0034] In this embodiment, the first baffle 5 is preferably movably connected to the bottom plate 1 through a sliding assembly, and the second baffle 6 is fixedly connected to the bottom plate 1 by bolt connection, plugging or welding. The sliding assembly includes a slide bar 8, a slider 9 and an adjustment block 10. The slide bar 8 is arranged on the bottom plate 1 and is arranged parallel to the bottom tube 2. The slider 9 is slidably matched with the slide bar 8. The adjustment block 10 is arranged on the slider 9. The adjustment block 10 is detachably connected to the bottom plate 1 through bolts 11. The first baffle 5 is arranged on the adjustment block 10. When the bottom pipe 2 needs to be inspected, the position of the adjustment block 10 needs to be fixed. At this time, the bolt 11 passes through the adjustment block 10 and the bottom plate 1 in sequence and is connected to the corresponding nut; when the spacing between the first baffle 5 and the second baffle 6 needs to be adjusted, the nut connected to the bolt 11 is loosened, and the slider 9 is slid along the slide bar 8. The adjustment block 10 and the slider 9 are fixed by bolt connection or welding, so when the slider 9 slides along the slide bar 8, the adjustment block 10 slides synchronously with the slider 9. When the adjustment block 10 slides close to the second baffle 6, the spacing between the first baffle 5 and the second baffle 6 becomes smaller. On the contrary, when the adjustment block 10 slides away from the second baffle 6, the spacing between the first baffle 5 and the second baffle 6 becomes larger. During the adjustment process, the change in the spacing between the first baffle 5 and the second baffle 6 can be visually observed with the help of the scale on the size reading device 7. After the position of the first baffle 5 relative to the second baffle 6 is adjusted to the right position, the bolt 11 passes through the adjustment block 10 and the bottom plate 1 in sequence and is connected to the corresponding nut, so that the position of the first baffle 5 can be fixed at this time. The bottom plate 1 is provided with a plurality of through holes, which can allow the bolts 11 to penetrate the through holes at corresponding positions on the bottom plate 1 when the first baffle plate 5 is at different positions, thereby fixing the first baffle plate 5 at different positions.

[0035] In this embodiment, the second baffle 6 is directly connected to the bottom plate 1, but the top of the second baffle 6 is flush with the top of the first baffle 5 to ensure that after the bottom tube 2 is placed in, the bottom tube 2 is in a horizontal state (the bottom tube 2 is generally parallel to the bottom plate 1).

[0036] In this embodiment, in order to improve the detection reliability of the bottom tube 2, a support block is also provided. The support block is located between the first baffle plate 5 and the second baffle plate 6, and is connected to the bottom plate 1 by bolt connection, plug-in connection or welding. The support block is used to support the part of the bottom tube 2 located between the two ends. Further, in this embodiment, two support blocks are preferably provided between the first baffle plate 5 and the second baffle plate 6, and the two support blocks are respectively a first support block 12 and a second support block 13, wherein the first support block 12 is close to the first baffle plate 5 and abuts against the end surface of one end of the slide bar 8. The first support block 12 is arranged higher than the slide bar 8, and plays a role in limiting the slider 9, which can prevent the slider 9 from slipping off the slide bar 8 when the adjustment block 10 slides close to the second baffle plate 6. The second support block 13 is located between the first support block 12 and the second baffle plate 6.

[0037] In this embodiment, Figure 2 and Figure 3 As shown, the tops of the first bracket 12 and the second bracket 13 are both provided with U-shaped grooves 14 for accommodating the bottom tube 2. The two U-shaped grooves 14 and the inner side of the top of the first baffle 5 (the side facing the second baffle 6) and the inner side of the top of the second baffle 6 (the side facing the first baffle 5) together form the aforementioned gauge cavity.

[0038] In this embodiment, a limit stopper 15 is further included, which is arranged on the bottom plate 1 by bolt connection, plugging or welding, and abuts against the other end surface of the slide bar 8. The limit stopper 15 is arranged higher than the slide bar 8, and plays a role in limiting the position of the slider 9, so as to prevent the slider 9 from slipping off the slide bar 8 when the adjustment block 10 slides away from the second baffle 6.

[0039] In this embodiment, the size reading device 7 can be a length scale line set on the bottom plate 1. Alternatively, the size reading device 7 is preferably a size plate, which is laid flat on the bottom plate 1, or vertically set on the limit stopper 15 and the second stopper 6, such as Figure 2 As shown, the two ends of the dimension plate are respectively fixed to the side walls of the limit stopper 15 and the second stopper 6 by bolts or screws. The middle part of the dimension plate can be selectively connected to the side wall of at least one of the first bracket 12 and the second bracket 13 by bolts or screws, which can improve the installation firmness of the dimension plate.

[0040] In this embodiment, in order to facilitate reading of the value on the size reading device 7, an indicator plate 16 is also provided. The indicator plate 16 is provided on the side wall of the adjustment block 10 and is located above the size reading device 7. A sharp corner 17 for indicating the value is provided at the bottom of the indicator plate 16, and the tip of the sharp corner 17 is aligned with the first baffle 5. The position of the first baffle 5 can be intuitively judged by the position of the sharp corner 17.

[0041] The working principle of the adjustable bottom tube inspection fixture 100 of the electric vehicle in this embodiment is described in detail below:

[0042] like Figure 2 and Figure 3As shown, the limit block 15, the first bracket 12, the second bracket 13 and the second baffle 6 are all welded and fixed to the bottom plate 1. The first baffle 5, the first bracket 12, the second bracket 13 and the second baffle 6 play the role of supporting the bottom tube 2 and fixing it on one side; the slider 9 is assembled to the slide bar 8, and the slide bar 8 is fixed to the bottom plate 1 with three bolts. The first baffle 5 is welded and fixed to the adjustment block 10, and the adjustment block 10 is fixed to the slider 9 with four bolts; the indicator plate 16 is fixed to the side wall of the adjustment block 10 with two bolts, and the size plate is fixed to the side wall of the limit block 15, the first bracket 12, the second bracket 13 and the second baffle 6 with bolts, which plays a role of visual adjustment as a whole. It is preferred that all parts of the inspection fixture except bolts and nuts are painted with paint, and the inspection fixture cavity is not painted. The paint coating can prevent rust and extend the service life.

[0043] When in use, loosen the four bolts 11 on the adjustment block 10, slide the slider 9 according to the drawing size of the bottom tube product 1, until the sharp corner 17 of the indicator plate 16 is aligned with the scale on the size plate corresponding to the drawing size of the bottom tube product 1, and tighten the four bolts 11. Then place the finished bottom tube in the current inspection fixture cavity to detect the length of the finished bottom tube. If you replace the bottom tube product 2 with a different length, you need to repeat the above steps to readjust the position of the slider 9 until the sharp corner 17 of the indicator plate 16 is aligned with the scale on the size plate corresponding to the drawing size of the bottom tube product 2, and then place the corresponding bottom tube in the current inspection fixture cavity to detect the length of the finished bottom tube.

[0044] The advantages of using the above-mentioned electric vehicle bottom tube adjustable check fixture 100 are:

[0045] First, the spacing between the first baffle plate 5 and the second baffle plate 6 is adjustable, and the adjustment size range is large, so that one inspection fixture can be used for multiple models, and the versatility is strong. After the model is withdrawn from the market, the inspection fixture can also be reused, avoiding the processing and material costs caused by changing the inspection fixture or designing a new inspection fixture, and avoiding waste of resources.

[0046] Second, the indicator plate and the dimension plate are added to make the distance between the first baffle and the second baffle visible, which is conducive to improving the convenience of operation of the inspection fixture.

[0047] 3. After adjusting the position of the first baffle, the adjustment block is fixed by bolts to ensure the reliability of the gauge when in use, and the size and quality of the gauge can be guaranteed.

[0048] Fourth, a sliding bar and a slider structure are used to adjust the distance between the first baffle 5 and the second baffle 6. The adjustment operation is simple, and the inspection fixture can be quickly changed according to different product drawings, and the operability is strong.

[0049] Embodiment 2

[0050] This embodiment provides an adjustable inspection fixture 100 for the bottom tube of an electric vehicle, which differs from the first embodiment in that the first baffle plate 5 and the second baffle plate 6 are both movably connected to the bottom plate 1 through a sliding assembly. The specific structure of the sliding assembly can be found in the first embodiment and will not be described in detail here. It should be noted that the slide bars 8 in the two sets of sliding assemblies can be separately provided, but the two are arranged in alignment; in addition, the slide bars 8 in the two sets of sliding assemblies can also share the same slide bar structure. In addition to the above differences, the remaining structures of the adjustable inspection fixture 100 for the bottom tube of an electric vehicle are the same as those in the first embodiment and will not be described in detail here.

[0051] The electric vehicle bottom tube adjustable inspection fixture 100 of this embodiment can also make the spacing between the first baffle 5 and the second baffle 6 adjustable, so that the length of the inspection fixture cavity can be adjusted, and then the bottom tubes 2 of different lengths in different models can be inspected to solve the problems of poor versatility, short service life, high consumption cost, and waste of resources in existing fixed inspection fixtures. However, since the first baffle 5 and the second baffle 6 can be slidably adjusted, this embodiment is more flexible and has a larger adjustment range than the first embodiment, but the adjustment steps are cumbersome, the work efficiency is low, and the manufacturing and maintenance costs of the equipment are increased.

[0052] Embodiment 3

[0053] In this embodiment, based on the first or second embodiment, the base plate 1 is further configured to be rectangular, circular or other shapes, and a plurality of reference holes 18 are provided on the base plate 1 for installing the base plate 1 at specific tooling or other corresponding positions.

[0054] like Figure 2 and Figure 3 As shown, the base plate 1 is a rectangular base plate, and a reference hole 18 is respectively formed at its four corners.

[0055] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
