Description

Technical Field

[0001] The invention belongs to the technical field of automobile battery fixing, and in particular relates to a fixing tool for new energy automobile battery detection. Background Art

[0002] In order to meet the power needs of new energy vehicles, automotive battery packs are generally composed of multiple batteries stacked in series. As the only power source of new energy vehicles, new energy vehicle batteries are the core components of new energy vehicles. Therefore, before the batteries of new energy vehicles are used, they need to be tested. During the test, a battery fixing device is needed to clamp and fix the battery to facilitate angle adjustment of the battery.

[0003] Prior art, such as publication number CN117554292A, discloses a battery fixing device for new energy vehicles, which belongs to the technical field of new energy vehicles and includes a test bench, wherein both sides of the top of the test bench are provided with vertical frames, and the top area of ​​the vertical frames is provided with lifting slots, and the lifting slot area is provided with a clamping mechanism and a lifting mechanism; the lifting mechanism includes a cylinder arch frame; the clamping mechanism includes an adjusting frame, a first motor, a screw rod, a slider, a connecting frame, a fixing frame, an electric push rod, and an L-shaped clamping block; a rotating assembly is installed in the connecting frame area. The present invention can perform lifting and flipping operations during the battery clamping process, without the need to release the fixed clamping and then flipping, and then clamping, thereby simplifying multiple steps, and through the angle adjustment mechanism, the change of the angle of the battery surface displayed in the clamping state can be adjusted to adapt to more detection environments, while greatly improving the battery detection rate, which is simple and practical.

[0004] However, the above technology still has the following problems: during the flipping operation, the clamping mechanism always maintains an abutment state with the battery, resulting in the two ends of the battery being always blocked, which is not conducive to a comprehensive inspection of the battery, and the method of fixing by external force clamping is also easy to damage the battery. Secondly, when the above technology flips the battery, there is no interception mechanism on the upper and lower sides of the battery, which makes the battery easy to detach from the clamp during the flipping process.

[0012] In the above-mentioned fixing tool for testing new energy vehicle batteries, four equidistant circumferentially distributed positioning holes are opened on the outer wall of the rotating seat, and the four positioning holes correspond to the four sides of the rotating seat. Four equidistant circumferentially distributed abutment columns are welded on the top outer wall of the floating frame, and the abutment columns are adapted to the positioning holes.

[0013] In the above-mentioned fixed tooling for new energy vehicle battery testing, four equidistant circumferentially distributed travel grooves are opened on the outer wall of the adjustment frame, and the distribution of the travel grooves is the same as that of the abutment columns.

[0014] In the above-mentioned fixed tooling for new energy vehicle battery testing, the limiting mechanism includes a mounting frame, which is located above the adjusting frame. The mounting frame is in a circular shape and its inner diameter is larger than the outer diameter of the floating frame. A pair of symmetrically distributed limiting blocks are welded on the outer wall of the mounting frame. The limiting blocks are slidably inserted in the travel groove. A rack 2 is welded on the outer wall of the mounting frame, and the rack 2 is meshed with the gear.

DETAILED DESCRIPTION

[0034] See also Figure 1-Figure 10 The present invention provides a technical solution: a fixed tool for testing a new energy vehicle battery, comprising a test bench 1, a bracket 11 is welded on the top outer wall of the test bench 1, a flip motor 2 is welded on the top outer wall of the bracket 11, an L-shaped flip frame 21 is welded on the main shaft of the flip motor 2, a rotating motor 3 is welded on the horizontal outer wall of the flip frame 21, a rotating seat 31 is welded on the main shaft of the rotating motor 3, the length and width of the rotating seat 31 are the same as those of the battery body 9, a plurality of limiting holes 32 are opened on the outer wall of the rotating seat 31, and the distribution of the limiting holes 32 corresponds one by one to the bolt holes 91 on the battery body 9, and also includes:

[0035] A positioning mechanism, used to align the battery body 9 with the rotating seat 31, so that the bolt hole 91 on the outer shell of the battery body 9 is aligned with the limit hole 32 on the rotating seat 31, and the positioning mechanism is arranged on the flip frame 21;

[0036] A limiting mechanism, used to fix the battery body 9 on the rotating seat 31 through the bolt hole 91, so as to achieve the effect of limiting the battery body 9, and the limiting mechanism is arranged on the flip frame 21;

[0037] And an interception mechanism is used to prevent the battery body 9 from falling off when it is turned over, and the interception mechanism is arranged in the limiting mechanism.

[0038] Specifically, the positioning mechanism includes an adjusting frame 4, an electric push rod 41 is welded on the outer wall of the horizontal side of the flip frame 21, and the output end of the electric push rod 41 is welded with the adjusting frame 4, the adjusting frame 4 is slidably sleeved on the main shaft of the rotating motor 3, the adjusting frame 4 is located below the rotating seat 31, and the rotating motor 3 is located between the rotating seat 31 and the adjusting frame 4. The outer wall of the main shaft section is slidably sleeved with a floating frame 5, and a spring 52 is welded between the outer wall of the floating frame 5 and the outer wall of the adjusting frame 4, a rack 43 is welded on the outer wall of the adjusting frame 4, and a gear 22 is welded on the outer wall of the flip frame 21. The rack 43 and the gear 22 are meshed with each other, and the rotating seat 31 The outer wall of the adjusting frame 4 is provided with four equidistant circumferentially distributed positioning holes 33, and the four positioning holes 33 correspond to the four sides of the rotating seat 31. Four equidistant circumferentially distributed abutment columns 51 are welded on the top outer wall of the floating frame 5, and the abutment columns 51 are adapted to the positioning holes 33. The outer wall of the adjusting frame 4 is provided with four equidistant circumferentially distributed travel grooves 42, and the distribution of the travel grooves 42 is the same as that of the abutment columns 51. A positioning block 54 is slidably inserted in each travel groove 42. Four equidistant circumferentially distributed connecting rods 53 are rotatably inserted on the outer wall of the floating frame 5, and the end of the connecting rod 53 away from the floating frame 5 is rotatably inserted on the outer wall of the positioning block 54.

[0039] Since the four positioning holes 33 correspond to the four sides of the rotating seat 31, the distribution of the travel groove 42 is the same as that of the abutment column 51, so that when the abutment column 51 is inserted into the positioning hole 33, the four sides of the rotating seat 31 are aligned with the four positioning blocks 54 one by one, so that the positioning between the rotating seat 31 and the positioning blocks 54 is realized, so that when the four positioning blocks 54 are retracted, the battery body 9 can be pushed to align with the rotating seat 31. Because the length and width of the rotating seat 31 are the same as those of the battery body 9, the distribution position of the limit hole 32 is the same as the bolt hole 91 on the battery body 9, so that the limit hole 32 is aligned with the bolt hole 91, and the floating frame 5 is slidably mounted on the main shaft of the rotating motor 3, the floating frame 5 is located above the adjusting frame 4, and the floating frame 5 is coaxially distributed with the mounting frame 6.

[0040] In the initial state, under the action of the spring 52, the floating frame 5 is away from the adjusting frame 4, so that under the action of the connecting rod 53, the four positioning blocks 54 are in an open state, the electric push rod 41 is in an extended state, and the adjusting frame 4 drives the floating frame 5 to just abut against the rotating seat 31, so that the abutting column 51 passes through the positioning hole 33.

[0041] The above-mentioned positioning mechanism is further explained: the battery body 9 is placed on the rotating seat 31, and the battery body 9 presses the abutment column 51 into the positioning hole 33, so that the abutment column 51 pushes the floating frame 5 to approach the adjusting frame 4, so that the floating frame 5 pulls the four positioning blocks 54 together through the connecting rod 53, and then the four positioning blocks 54 push the four sides of the battery body 9 to align with the rotating seat 31, and the positioning blocks 54 are driven to slide and retract by the self-gravity of the battery body 9 to achieve the effect of automatic positioning. The operation is simple and quick, which is conducive to improving work efficiency. In addition, a pulley can be added to the top outer wall of the rotating seat 31 to reduce the wear between the battery body 9 and the rotating seat 31.

[0042] Specifically, the limiting mechanism includes a mounting frame 6, which is located above the adjusting frame 4. The mounting frame 6 is annular and its inner diameter is larger than the outer diameter of the floating frame 5. A pair of symmetrically distributed limiting blocks 63 are welded on the outer wall of the mounting frame 6, and the limiting blocks 63 are slidably inserted in the travel groove 42. A rack 2 62 is welded on the outer wall of the mounting frame 6, and the rack 2 62 is meshed with the gear 22. A avoiding groove 64 adapted to the connecting rod 53 is provided on the outer wall of the mounting frame 6. An arc-shaped slide groove 61 is provided on the outer wall of the mounting frame 6, and a pair of slide seats 7 are slidably inserted in the slide groove 61. An electric push rod 2 71 is welded on the outer wall of each slide seat 7, and a limiting column 72 is welded on the output end of each electric push rod 2 71. The two limiting columns 72 are slidably inserted in the two limiting holes 32 located on the diagonal line of the rotating seat 31.

[0043] By limiting any two bolt holes 91 on the battery body 9, the rotational freedom of the battery body 9 can be limited so that the battery body 9 can only rotate along with the rotating seat 31. In this embodiment, by limiting the two bolt holes 91 on the diagonal line, the force on the battery body 9 can be more evenly applied, thereby avoiding concentrated force on one side of the battery body 9 and deformation.

[0044] In the initial state, under the transmission action of the gear 22 , the mounting bracket 6 is away from the rotating seat 31 , and the top end of the limiting column 72 is just retracted into the limiting hole 32 .

[0045] The above-mentioned limiting mechanism is further explained: when the positioning is completed, the electric push rod 41 is controlled to retract, so that the adjusting frame 4 drives the rack 43 to move downward, and under the transmission action of the rack 43, the gear 22 and the rack 2 62, the rack 2 62 drives the mounting frame 6 to move upward, so that the slide 7 drives the limiting column 72 to pass through the limiting hole 32, and then the limiting column 72 is inserted into the bolt hole 91 on the battery body 9, so that the battery body 9 and the rotating seat 31 are fixed together, and the floating frame 5 moves downward with the adjusting frame 4, so that the abutment column 51 is completely disengaged from the positioning hole 33, and the slide 7 can slide relative to the mounting frame 6 in the slide groove 61, so that when the rotating motor 3 drives the rotating seat 31 to rotate, the rotating seat 31 drives the battery body 9 to rotate through the limiting column 72, so that the angle of the battery body 9 is adjusted, which is convenient for comprehensive detection.

[0046] Specifically, the intercepting mechanism includes a screw 8, and each limiting column 72 is provided with an axially distributed installation groove 721, and a screw 8 is rotatably inserted on the bottom inner wall of the installation groove 721, and the screw 8 extends to the top of the limiting column 72, and a slider 81 is threadedly fitted on the outer wall of the screw 8, and the slider 81 is slidably inserted in the installation groove 721, and a block 82 is rotatably inserted on the outer wall of the slider 81, and a limiting groove 821 is provided on the outer wall of the block 82, and a fixed shaft 722 is welded on the inner wall of the installation groove 721, and the block 82 is slidably fitted on the outer wall of the fixed shaft 722 through the limiting groove 821.

[0047] In the initial state, the electric push rod 2 71 is in a retracted state, the sliding block 81 is away from the top of the screw 8 , and the clamping block 82 is received in the mounting groove 721 .

[0048] The above-mentioned interception mechanism is further elaborated: when the limiting is completed, the extension height of the limiting column 72 is controlled by the electric push rod 2 71, so that the limiting column 72 can limit the multiple superimposed battery bodies 9, so that the present device can be directly applicable to fix the superimposed battery pack, by rotating the screw 8, the slider 81 slides toward the top of the screw 8, so that the block 82 is pushed out of the mounting groove 721, and the block 82 can be kept in the extended state through the self-locking effect of the thread, so that the block 82 can intercept the battery body 9 from above to avoid falling off during the flipping process, and the flip motor 2 is started to drive the flip frame 21 to rotate, and the flip frame 21 drives the rotating seat 31 to flip, so that the battery body 9 can be flipped to any angle, which is convenient for comprehensive detection. When the battery body 9 is flipped one hundred and eighty degrees, the electric push rod 2 71 is controlled to extend. Under the interception effect of the block 82, the battery body 9 moves away from the rotating seat 31 along with the limiting column 72, so that the side of the battery body 9 blocked by the rotating seat 31 is exposed, avoiding the situation of blocking in the traditional fixing method.

[0049] The working principle and use process of the present invention are as follows: the battery body 9 is placed on the rotating seat 31, and the battery body 9 presses the abutment column 51 into the positioning hole 33. Under the action of the positioning mechanism, the floating frame 5 pulls the four positioning blocks 54 together through the connecting rod 53, so that the four positioning blocks 54 push the four sides of the battery body 9 to align with the rotating seat 31. When the positioning is completed, the electric push rod 1 41 is controlled to shrink, so that the adjustment frame 4 drives the rack 1 43 to move downward. Under the action of the limiting mechanism, the sliding seat 7 drives the limiting column 72 to pass through the limiting hole 32, so that the limiting column 72 is inserted into the bolt hole 91 on the battery body 9, so that the battery body 9 and the rotating seat 31 are fixed together, so that The rotating seat 31 can drive the battery body 9 to rotate through the limiting column 72, so as to adjust the angle of the battery body 9 and facilitate comprehensive detection. When the limiting is completed, the screw 8 is rotated so that the block 82 is pushed out of the mounting groove 721 under the action of the interception mechanism, so that the block 82 can intercept the battery body 9 from above, and then the flip frame 21 will not fall off when driving the battery body 9 to flip, and by controlling the extension length of the electric push rod 71, the battery body 9 can move away from the rotating seat 31 along the limiting column 72, so that the side of the battery body 9 blocked by the rotating seat 31 is exposed, avoiding the obstruction of the traditional fixing method.
