[0032] The present invention is further described in detail below with reference to the embodiments.

[0033] Specific embodiments of the battery cell beading inspection tool provided by the utility model:

[0034] See also Figure 1-8 , the battery cell pressure strip inspection fixture includes a platform 1; the platform 1 is made of cast aluminum, and a frame 9 is provided on the lower side of the platform 1. The frame 9 enables the platform 1 to have a suitable operating height. Casters 10 are installed on the lower side of the frame 9. The casters 10 make the inspection fixture easy to move, and the casters 10 preferably have a universal wheel with a braking structure.

[0035] Six reference blocks 11 are set on the upper side of the table 1, four of which are located at the four corners of the table 1 and two are located at the two side edges of the middle of the table 1; after the inspection fixture is completed, the reference block 11 serves as the Z-axis direction reference for three-dimensional coordinate detection.

[0036] A support body 2 is provided on the upper middle side of the table top 1. The support body 2 is a long plate-like structure, and a positioning surface for supporting the pressure strip body 31 is provided on the upper side of the support body 2. In this embodiment, the support body 2 is divided into several sections, and each section of the support body 2 is connected to the table top 1 by bolts; so that the support body 2 can be easily replaced, especially the replacement of the rightmost section of the support body 2 can adapt to the support of pressure strip bodies 31 of different specifications and lengths; the upper positioning surfaces of each section of the support body 2 are flush, and the pressure strip body 31 can be vertically positioned.

[0037] The inspection fixture in this embodiment is equipped with four sizes of go / no-go gauges 8 to accommodate different bolt hole inspections at the ends of the beading body 31. Inspection holes (not shown) that mate with the go / no-go gauges 8 are provided on the upper sides of both ends of the support body 2. The inspection holes are located on the leftmost and rightmost sections of the support body 2. When the beading body 31 is qualified, the bolt holes at both ends of the beading body 31 can correspond to the inspection holes. Go / no-go gauges 8 of corresponding sizes can pass through the ends of the beading body 31 and enter the inspection holes at the ends of the support body 2. When the bolt hole positions of the beading body 31 are unqualified, the go / no-go gauges 8 cannot enter the inspection holes of the support body 2.

[0038] like Figure 1 and Figure 8 As shown, a plurality of brackets 15 for placing go / no-go gauges 8 are provided on the upper edge of the table 1, and the brackets 15 are connected to the table 1 by bolts.

[0039] Positioning blocks 3 are provided on one side of each end of the support body 2 to limit the lateral position of the bead body 31. The positioning blocks 3 are located on the leftmost and rightmost sections of the support body 2, respectively. A push rod 4 is provided on the upper side of each end of the tabletop 1 to push the end of the bead body 31 against the side of the positioning blocks 3, and a spring 5 is provided to support the push rod 4. The spring 5 enables the push rod 4 to push the end of the bead body 31 against the side of the positioning block 3, thereby achieving the lateral positioning of the bead body 31.

[0040] Supports 16 are located on the upper sides of both ends of the tabletop 1. The push rod 4 passes through these supports. Supports 16 have a through-hole for the push rod 4. The inner diameter of this through-hole is larger than the outer diameter of the push rod 4, allowing the push rod 4 to be pulled axially and rotated about its own axis. A stopper 17 and a handle 18 are located outside the push rod 4 on either side of the support 16. The outer diameters of these two blocks are larger than the outer diameter of the push rod 4 and larger than the inner diameter of the through-hole in the support 16. The stopper 17 is closer to the positioning block 3 than the handle 18. The spring 5 mentioned above is sleeved around the outside of the push rod 4 between the stopper 17 and the support 16.

[0041] The support 16 has a groove 19 on the side facing the handle 18, and a limiting rod 20 is provided on one side of the push rod 4, which extends into the groove 19. When the limiting rod 20 aligns with the groove 19, the spring 5 causes the push rod 4 to move toward the bead body 31, where it cooperates with the positioning block 3 to compress the bead body 31 and force the limiting rod 20 into the groove 19. Pulling the handle 18 causes the push rod 4 to move away from the bead body 31, and the limiting block 17 compresses the spring 5, causing the limiting rod 20 to disengage from the groove 19. Rotating the push rod 4 prevents the limiting rod 20 from aligning with the groove 19, preventing the push rod 4 from moving toward the bead body 31. To compress the bead body 31, the handle 18 and push rod 4 are rotated so that the limiting rod 20 aligns with the groove 19, and the spring 5 forces the push rod 4 to press against the bead body 31. In some embodiments, a nylon block may be provided at the contact end between the push rod 4 and the bead body 31 to protect the surface of the bead body 31.

[0042] The support 16 at the left end of the table top 1 is connected to the table top 1 by bolts. The support 16 at the right end of the table top 1 is slidably connected to the table top 1, so that the top rod 4 at the right end of the table top 1 can change its position to adapt to the ends of the pressure strip body 31 of different lengths. Specifically, the right end of the table top 1 is provided with a first slide rail 21 and a first slide 22 sliding along the first slide rail 21. The first slide rail 21 is parallel to the extension direction of the pressure strip body 31. The support 16 at the right end of the table top 1 is connected to the upper side of the first slide 22. The top rod 4 and the spring 5 at the right end of the table top 1 are connected to the upper side of the first slide 22 through the right end support 16. Both ends of the first slide rail 21 are provided with a first anti-collision block 23 corresponding to the position of the support 16. The first anti-collision block 23 is made of rubber. In some embodiments, the first anti-collision block 23 is supported by an elastic telescopic rod.

[0043] The upper side of the tabletop 1 is linearly connected to the movable frame 6. Specifically, a second slide rail 25 and a second slide 24 that slides along the second slide rail 25 are provided on the upper side of the tabletop 1. The movable frame 6 is connected to the second slide 24. Second bumpers 26 are provided at each end of the second slide rail 25, corresponding to the position of the movable frame 6. The second bumpers 26 are made of rubber and, in some embodiments, are supported by elastic telescopic rods. The second slide rail 25 is parallel to the first slide rail 21, but is significantly longer than the first slide rail 21. The length of the second slide rail 25 is also greater than the length of the support body 2, allowing for comprehensive inspection of the bead body 31.

[0044] Three dial indicators 7 are mounted on the movable frame 6, two of which are horizontally aligned with the sides of the beading body 31, and one of which is vertically aligned with the top side of the beading body 31. The tabletop 1 is equipped with several zeroing seats 12 for zeroing the dial indicators 7. Three storage boxes 13 for storing the dial indicators 7 are also located on the tabletop 1. Each box has a slot for placing the dial indicators 7, and a lid 14 is rotatably connected to the top of the box.

[0045] The movable frame 6 is shaped like an inverted U and is provided with three mounting holes 29. The three dial indicators 7 pass through the three mounting holes 29, respectively. Three butterfly bolts 30 are threadedly connected to the movable frame 6 to secure the dial indicators 7. The inner ends of the butterfly bolts 30 extend into the mounting holes 29 and contact the middle of the dial indicators 7, securing the dial indicators 7 in the mounting holes 29. By loosening the butterfly bolts 30, the dial indicators 7 can be removed. The contacts of the three dial indicators 7 contact the three side surfaces of the pressure strip body 31, respectively.

[0046] A positioning pin 27 is vertically passed through the bottom of the movable frame 6, and a handle is connected to the upper end of the positioning pin 27. A pin hole 28 is provided on the upper left side of the table 1 to match the positioning pin 27, which serves as the starting point for detection.

[0047] The positioning pin 27 enters the pin hole 28, restricting the sliding movement of the movable frame 6 and the second slide 24. The dial indicators 7 are then installed, ensuring that their contacts contact the pressure strip body 31 and that the starting position readings of the three dial indicators 7 are the same. The dial indicators 7 are then secured with the butterfly bolts 30. The positioning pin 27 is disengaged from the pin hole 28, and the second slide 24 and movable frame 6 are slowly moved gradually to the right along the second slide rail 25. During this movement, the readings of the dial indicators 7 are observed. Excessive changes indicate that the product is unqualified. A reading within the allowable range indicates that the product is qualified.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments without inventive effort, or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
