Description

Technical Field

[0001] This invention relates to the field of new energy vehicle parts testing technology, and in particular to a testing device for new energy vehicle parts. Background Technology

[0002] As the market demand for new energy vehicles continues to increase, the demand for new energy vehicle parts is also growing. After the production of some auto parts, in order to ensure the quality of the auto parts, workers usually need to perform positional accuracy testing.

[0003] like Figure 1 The new energy vehicle component shown includes a support, a first sleeve, and two second sleeves. Each first sleeve and second sleeve is present in pairs, welded to the four corners of the support. Both the first and second sleeves are used to mount the external mechanism's support pillars; therefore, the positional accuracy of the first and second sleeves needs to be checked. Currently, multiple support pillars are used to support the sleeves of the new energy vehicle component before testing. However, a height difference inevitably exists between the welding heights of the first and second sleeves. This height difference is typically addressed by adding shims between the support pillar and the first or second sleeve. However, since the height difference is uncertain, it requires repeated trials with shims of different thicknesses and adjustments to multiple first or second sleeves, making the operation cumbersome and inconvenient. Summary of the Invention

There are two bases 44 and two columns 45, which correspond one to one. The two bases 44 are respectively installed at both ends of the swing rod 43. The columns 45 are installed on the bases 44. The columns 45 are used to abut against the bottom of the second sleeve 93 of the new energy vehicle part 90. The positioning assembly 50 also includes a first positioning member 51 and a second positioning member 52. The first positioning member 51 and the second positioning member 52 are respectively inserted into the two supports 32. The first positioning member 51 and the second positioning member 52 abut against the inner sidewalls of the two first sleeves 92. In one embodiment, the new energy vehicle component 90 includes a support member 91, a first sleeve 92, and a second sleeve 93. There are two first sleeves 92 and two second sleeves 93, which are welded to the four end corners of the support member 91. Both the first sleeves 92 and the second sleeves 93 are used to mount the support columns 33 of the external mechanism. Optionally, the two first sleeves 92 are symmetrically arranged along the axis of symmetry of the support member 91, and the two second sleeves 93 are also symmetrically arranged along the axis of symmetry of the support member 91. The detection device 100 for new energy vehicle components uses the bottoms of the two first sleeves 92 to abut against the corresponding support columns 33. Under the action of the swing arm 43, the bottoms of the two second sleeves 93 abut against the corresponding uprights 45, thereby providing sufficient support force and achieving adaptive height difference adaptation of the second sleeves 93, making it convenient to use.

[0025] like Figure 2 As shown, in this embodiment, the measuring machine 10 is a three-dimensional measuring machine, which is the prior art; the trolley 20 is a handcart, which is the prior art.

[0026] like Figures 3 to 5As shown, the support assembly 30 includes a base plate 31, a support 32, and a support column 33. The base plate 31 is mounted on the trolley 20, and the support 32 is mounted on the base plate 31. There are two supports 32 and two support columns 33, and they correspond one-to-one. The two supports 32 are respectively mounted on both ends of the base plate 31. The support column 33 is mounted on the support 32 and is used to abut the bottom of the first sleeve 92 of the new energy vehicle part 90. Optionally, the support column 33 includes a first support rod portion (not shown) and a second support rod portion 332 connected to the first support rod portion. The first support rod portion is inserted into the support 32. The diameter of the second support rod portion 332 is larger than that of the first support rod portion. A limiting portion 3321 is provided on one side of the second support rod portion 332. Further, the limiting portion 3321 is a plane. One end of the second support rod portion 332 is a plane to abut against the bottom of the first sleeve 92 of the new energy vehicle part 90. A scale (not shown) is provided on one side of the second support rod portion 332.

[0027] like Figure 5 As shown, the support assembly 30 further includes a first fastener 34 and a first limiting block 35. One end of the first fastener 34 passes through the support 32 and the support column 33, and the first fastener 34 is used to fix the support 32 and the support column 33. Optionally, the first fastener 34 is threadedly connected to the support column 33. Further, one end of the first fastener 34 is inserted into the end of the first support rod portion away from the second support rod portion 332. The first limiting block 35 is installed on the support 32, and one side of the first limiting block 35 is used to abut against one side of the support column 33. Further, one side of the first limiting block 35 abuts against the limiting portion 3321 to prevent the support column 33 from rotating. In one embodiment, there are two first fasteners 34 and two first limiting blocks 35, and each corresponds to one support column 33.

[0028] In one embodiment, the support assembly 30 further includes a first washer 36, which is sleeved on the support column 33.

Optionally, the first washer 36 is sleeved on a first support rod portion, and one end of the first washer 36 abuts against a second support rod portion 332. The first washer 36 limits the distance between the second support rod portion 332 and the support 32, thereby adjusting the distance between the first sleeve 92 and the support 32 and improving the positioning accuracy. Further, there are multiple first washers 36, and each support column 33 is equipped with a first washer 36. Even further, each support column 33 is equipped with multiple stacked first washers 36 to accommodate first sleeves 92 of different heights. In use, the first washer 36 is fitted onto the first support rod, and then the first support rod with the first washer 36 is inserted into the support 32. The support 32 and the first support rod are then fixed by the first fastener 34. Next, the first limiting block 35 is installed on the support 32, and one side of the first limiting block 35 abuts against the limiting part 3321 to prevent the support column 33 from rotating. At the same time, the scale on the second support rod 332 is indicated by one side of the first limiting block 35, which further improves the positioning accuracy and makes it easier to adjust the height of the two columns 45.

[0029] like Figure 3 and Figure 5 As shown, the support assembly 30 further includes a first fixing seat 37 and a first clamping member 38. The first fixing seat 37 is installed on one side of the support 32, and the first clamping member 38 is installed on the first fixing seat 37. The first clamping member 38 is used to abut against the top of the first sleeve 92 of the new energy vehicle part 90, thereby fixing the first sleeve 92. There are two first fixing seats 37 and two first clamping members 38, and they correspond one-to-one with the support column 33. Optionally, the first clamping member 38 is a manual clamp, which is the prior art. In other embodiments, the first clamping member 38 is a pneumatic clamp.

The mounting base 41 is installed on the side of the base plate 31 away from the support 32. The rotating shaft 42 is rotatably connected to the mounting base 41, and the rotating shaft 42 passes through the central axis of the swing rod 43. There are two bases 44 and two columns 45, which correspond one-to-one. The two bases 44 are respectively installed at both ends of the swing rod 43, and the columns 45 are installed on the bases 44. The columns 45 are used to abut the bottom of the second sleeve 93 of the new energy vehicle part 90. Optionally, the axis of symmetry of the base plate 31, the central axis of the mounting base 41, the axis of symmetry of the rotating shaft 42, and the central axis of the swing rod 43 correspond. When the new energy vehicle part 90 is placed on the column 45, the central axis of the mounting base 41 is collinear with the axis of symmetry of the support 91. Further, the swing rod 43 is elongated. In one embodiment, the structure of the column 45 is similar to that of the support column 33, and will not be described in detail below.

[0031] like Figure 6 As shown, the adjustment assembly 40 further includes a second fastener 46 and a second limiting block 47. One end of the second fastener 46 passes through the base 44 and the column 45, and the second fastener 46 is used to fix the base 44 and the column 45. The second limiting block 47 is installed on the base 44, and one side of the second limiting block 47 is used to abut against one side of the column 45 to prevent the column 45 from rotating. There are two of each of the second fasteners 46 and the second limiting block 47, and they correspond one-to-one with the columns 45. Optionally, the adjustment assembly 40 further includes a second washer 48, which is sleeved on the column 45. One end of the second washer 48 abuts against the base 44, and the other end abuts against the column 45. There are multiple second washers 48, and each column 45 is equipped with a second washer 48. In one embodiment, the second fastener 46 is similar in structure to the first fastener 34, the second limiting block 47 is similar to the first limiting block 35, and the second washer 48 is similar to the first washer 36, which will not be described in detail below.

The second fixing seat 49 is installed at one end of the swing arm 43, and the second clamping member 41a is installed on the second fixing seat 49. The second clamping member 41a is used to abut against the top of the second sleeve 93 of the new energy vehicle part 90, thereby fixing the second sleeve 93. There are two of each of the second fixing seat 49 and the second clamping member 41a, and they correspond one-to-one with the column 45. In one embodiment, the second clamping member 41a has a similar structure to the first clamping member 38, which will not be described in detail below.

[0033] Please check again. Figure 4 and Figure 6 The adjustment assembly 40 further includes a first support base 42a, a first stop block 43a, a second support base (not shown in the figure), and a second stop block 44a. The first support base 42a and the second support base are respectively installed on the base plate 31. The first stop block 43a is installed on the first support base 42a, and the second stop block 44a is installed on the second support base. The first stop block 43a and the second stop block 44a correspond to the two ends of the swing rod 43. When the swing rod 43 is in a balanced state, there is a gap between the first stop block 43a and the swing rod 43, and between the second stop block 44a and the swing rod 43. This gap is the allowable deviation. When the first sleeve 92 of the new energy vehicle part 90 is placed on the support column 33 and the second sleeve 93 is placed on the column 45, if one end of the swing rod 43 abuts against the first stop block 43a or the second stop block 44a, it indicates that the welding of the new energy vehicle part 90 is unqualified, that is, the welding deviation of the second sleeve 93 is large, which plays a preliminary inspection role and does not need to be inspected by the measuring machine 10, thus improving the inspection efficiency; if there is still a gap between the first stop block 43a and the swing rod 43, and between the second stop block 44a and the swing rod 43, it indicates that the welding of the second sleeve 93 of the new energy vehicle part 90 is qualified.

[0034] In one embodiment, the first stop 43a includes a first connecting portion (not shown), a second connecting portion 432a, and a third connecting portion 433a connected in sequence.

Optionally, the diameter of the second connecting portion 432a is larger than the diameter of the first connecting portion. In one embodiment, the second stop 44a has a similar structure to the first stop 43a, which will not be described in detail below.

[0035] The adjustment assembly 40 further includes a first locking member (not shown) and a second locking member (not shown). The first locking member is used to fix the first stop 43a and the first support 42a; the second locking member is used to fix the second stop 44a and the second support 42a. Optionally, the first locking member is threadedly connected to the first stop 43a; further, one end of the first locking member is inserted into the end of the first connecting portion away from the second connecting portion 432a. In one embodiment, the structures of the first fastener 34, the first locking member, and the second locking member are similar, and will not be described in detail below.

[0036] like Figure 6As shown, the adjustment assembly 40 further includes a first partition 45a and a second partition (not shown in the figure). The first partition 45a is sleeved on the first stop 43a, with one end of the first partition 45a abutting against the first support 42a and the other end abutting against the first stop 43a. The second partition is sleeved on the second stop 44a, with one end of the second partition abutting against the second support and the other end abutting against the second stop 44a. Optionally, the first partition 45a is sleeved on the first connecting portion; one end of the first partition 45a abuts against the first support base 42a, and the other end abuts against the second connecting portion 432a; the first partition 45a limits the distance between the second connecting portion 432a and the first support base 42a, thereby adjusting the distance between the second sleeve 93 and the first support base 42a and improving the positioning accuracy; furthermore, there are multiple first partitions 45a, and multiple stacked first partitions 45a are installed on the first stop block 43a to accommodate second sleeves 93 of different heights; in one embodiment, the structure of the second partition is similar to that of the first partition 45a, which will not be described in detail below.

[0037] like Figure 7 As shown, the adjustment assembly 40 further includes a support block 46a and a pin 47a. The support block 46a is installed on the first support base 42a. One end of the pin 47a slides on the support block 46a, and the other end is used to insert the swing rod 43. When the pin 47a is inserted into the swing rod 43, the swing rod 43 is in a balanced state, preventing the swing rod 43 from swinging during movement. During detection, the pin 47a is pulled out until it disengages from the swing rod 43, allowing the swing rod 43 to swing freely. In one embodiment, the adjustment assembly 40 further includes a linkage 48a and two bearing seats 49a. The linkage 48a is sleeved on the rotating shaft 42 and is detachably installed in the middle of the swing rod 43 to allow for the replacement of different swing rods 43. The two bearing seats 49a are respectively installed on both sides of the mounting base 41, and the two ends of the rotating shaft 42 are rotatably connected to the two bearing seats 49a.

[0038] like Figure 3 and Figure 7As shown, the positioning assembly 50 further includes a first positioning member 51 and a second positioning member 52. The first positioning member 51 and the second positioning member 52 are respectively inserted into two supports 32. The first positioning member 51 and the second positioning member 52 abut against the inner sidewalls of the two first sleeves 92 to fix the position of the new energy vehicle part 90 and prevent movement. Optionally, the first positioning member 51 and the second positioning member 52 are both vertically installed on the supports 32. The verticality of the first sleeve 92 can be detected by the first positioning member 51 and the second positioning member 52. If the first positioning member 51 and the second positioning member 52 can abut against the inner sidewall of the first sleeve 92, it indicates that the first sleeve 92 is vertically welded. Optionally, one end of the first positioning member 51 has a polygonal cross-section, and one end of the second positioning member 52 has a polygonal cross-section.

[0039] In use, the number of first washers 36 and second washers 48 are adjusted according to the accuracy requirements of the welding positions of the two first sleeves 92 and the two second sleeves 93; the number of first stops 43a and second stops 44a is adjusted according to the allowable deviation; then, the first positioning member 51 is inserted into one of the supports 32, and the second positioning member 52 is inserted into the other support 32. Then, the two first sleeves 92 are placed on the corresponding pillars 33, so that the bottom of the first sleeve 92 abuts against the pillar 33, and the outer wall of the first positioning member 51 abuts against the inner wall of the corresponding first sleeve 92, and the outer wall of the second positioning member 52 abuts against the inner wall of the corresponding second sleeve 93, thereby fixing the horizontal position of the new energy vehicle part 90; specifically, if the bottom of one of the first sleeves 92 cannot abut against the pillar 33, the first washer 36 needs to be added or replaced so that both first sleeves 92 abut against the pillar 33. Then, the two second sleeves 93 are placed on the corresponding columns 45. Under the action of the swing rod 43, the bottoms of both second sleeves 93 abut against the columns 45. Finally, the top of the first sleeve 92 is pressed by the first clamping member 38, thereby fixing the vertical position of the first sleeve 92. Then, the top of the second sleeve 93 is pressed by the second clamping member 41a, thereby fixing the vertical position of the first sleeve 92. Moreover, the second clamping member 41a always remains parallel to the swing rod 43, thereby avoiding damage to the second sleeves 93. By having both first sleeves 92 abut against the column 33 and both second sleeves 93 abut against the column 45, sufficient support force is provided, improving detection accuracy. The swing of the swing rod 43 enables adaptive adjustment of the height difference of the second sleeves 93, making it convenient to use.

[0040] The detection device 100 for new energy vehicle parts of the present invention has two first sleeves 92 whose bottoms abut against the corresponding support columns 33 respectively. Under the action of the swing rod 43, the bottoms of the two second sleeves 93 abut against the corresponding columns 45 respectively, thereby providing sufficient support force and realizing adaptive height difference of the second sleeves 93, which is convenient to use.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
