Description

Technical Field

[0001] This utility model belongs to the field of battery bracket technology, and in particular relates to a riveting and positioning device for battery brackets. Background Technology

[0002] Riveting and positioning devices for battery brackets are key tooling equipment in the manufacturing of new energy vehicles and energy storage systems. They are mainly used to achieve precise fixing and rapid riveting of brackets during battery pack assembly. Their core function is to solve problems such as positioning errors, low efficiency, and damage risks caused by traditional welding or bolting connections. Through positioning structures, such as fixing rods and positioning pins, the positioning device aligns one-to-one with the battery pack fixing holes, ensuring that the bracket holes and battery pack installation points are completely aligned. However, due to long-term use, the riveting and positioning device experiences mechanical wear on key components such as positioning pins and fixing rods, and accuracy deviations can easily exceed tolerance limits, leading to misalignment of holes after riveting and battery pack installation failure. Summary of the Invention

[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A riveting and positioning device for a battery holder includes a fixing plate, two mounting plates, two elastic support mechanisms, and four adjustable positioning mechanisms.

[0006] The two mounting plates are symmetrically arranged on the left and right sides of the fixing plate;

[0007] Two of the aforementioned elastic support mechanisms are symmetrically arranged on the upper end face of the fixed plate, and the elastic support mechanisms are used to support the bottom or top end face of the battery bracket;

[0008] All four adjustable positioning mechanisms are disposed on the upper surface of the fixed plate. The four adjustable positioning mechanisms are symmetrically disposed between the two elastic support mechanisms. The adjustable positioning mechanisms can cooperate with the holes of the battery bracket.

[0009] The adjustable positioning mechanism includes a retractable pin structure, a positioning guide structure, and a riveting base. The riveting base is detachably connected to the upper end face of the fixed plate. The top of the riveting base is provided with an annular riveting groove, and the middle of the riveting base is provided with a through hole. The top of the through hole is provided with a first annular baffle for limiting the bottom of the retractable pin structure. The positioning guide structure is disposed inside the through hole, and the top of the positioning guide structure is connected to the retractable pin structure. The positioning guide structure slides with the fixed plate, and the top of the retractable pin structure can mate with the hole of the battery bracket.

[0010] Furthermore, the retractable pin structure includes a locking structure, a fixing sleeve, and a positioning pin. The bottom of the fixing sleeve is provided with a second annular baffle, which is disposed inside the first annular baffle. The fixing sleeve is threadedly engaged with the positioning pin, and the positioning pin is connected and fixed to the positioning pin through the locking structure.

[0011] Furthermore, the locking structure is a retaining ring, which is threaded into the outer wall of the positioning pin.

[0012] Furthermore, the retractable pin structure also includes a buffer structure, which includes a limiting stop and a polyurethane flexible bushing. The limiting stop is disposed at the bottom of the inner side of the fixed sleeve, and the limiting stop is used to limit the bottom of the polyurethane flexible bushing. The top of the polyurethane flexible bushing abuts against the bottom of the positioning pin.

[0013] Furthermore, the positioning guide structure includes a reset spring and multiple slide rods. The multiple slide rods are evenly arranged circumferentially within the through hole. Each slide rod slides in contact with the fixed plate. The top of each slide rod is threaded to the bottom of the positioning pin. A limiting block is provided at the bottom of each slide rod.

[0014] Furthermore, the top of the positioning pin is provided with multiple guide slopes, which are evenly arranged circumferentially on the top of the positioning pin, and the guide slopes can cooperate with the holes of the battery bracket.

[0015] Furthermore, the inner side of the riveting base is connected to the upper surface of the fixing plate via a threaded sleeve.

[0016] Furthermore, the mounting plate has an L-shaped cross-section, and two elongated holes are provided at the outer end of the mounting plate.

[0017] Furthermore, the elastic support mechanism includes a support plate and multiple elastic components, and the support plate is connected to the upper surface of the fixed plate through the multiple elastic components.

[0018] Compared with the prior art, the riveting and positioning device for battery holders described in this utility model has the following advantages:

[0019] 1. A threaded fixed sleeve and locating pin enable precise adjustment of the pin, while a locking structure rigidly fixes its position. This actively counteracts clearance deviations caused by long-term wear, ensuring the pin tip always precisely aligns with the battery bracket hole. The evenly distributed sliding rods and return springs in the locating guide structure work together to maintain a strictly vertical movement trajectory of the pin during extension and retraction. The sliding fit between the sliding rods and the fixed plate eliminates the risk of radial offset, guaranteeing the coaxiality of the locating pin and the bracket hole.

[0020] 2. The polyurethane flexible bushing, constrained by the limiting flange, abuts against the bottom of the positioning pin. Utilizing the material's elastic deformation characteristics, it absorbs the instantaneous impact force during riveting, preventing stress transmission to precision components through hard contact. This significantly reduces the interference of riveting vibration on positioning accuracy and also reduces equipment structural noise. The flexible bushing isolates metal components from direct collisions, and the spring system shares the dynamic load, collectively reducing the rate of mechanical wear and extending the service life of core components.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] A riveting and positioning device for a battery holder, such as Figure 1 As shown, the device includes a fixed plate 100, two mounting plates 110, two elastic support mechanisms, and four adjustable positioning mechanisms. The two mounting plates 110 are symmetrically arranged on the left and right sides of the fixed plate 100. The two elastic support mechanisms are symmetrically arranged on the upper surface of the fixed plate 100, and are used to support the bottom or top surface of the battery holder. The four adjustable positioning mechanisms are all arranged on the upper surface of the fixed plate 100, and are symmetrically arranged between the two elastic support mechanisms. The adjustable positioning mechanisms can cooperate with the holes of the battery holder.

[0033] The adjustable positioning mechanism includes a retractable pin structure, a positioning guide structure, and a riveting base 300. The riveting base 300 is detachably connected to the upper end face of the fixing plate 100. The top of the riveting base 300 is provided with an annular riveting groove 310, and the middle of the riveting base 300 is provided with a through hole. The top of the through hole is provided with a first annular baffle for limiting the bottom of the retractable pin structure. The positioning guide structure is located inside the through hole. The top of the positioning guide structure is connected to the retractable pin structure. The positioning guide structure is slidably engaged with the fixing plate 100. The top of the retractable pin structure can engage with the hole of the battery holder.

[0034] like Figure 3 As shown, the retractable pin structure includes a locking structure 430, a fixing sleeve 410, and a positioning pin 420. The bottom of the fixing sleeve 410 is provided with a second annular baffle, which is located inside the first annular baffle. The fixing sleeve 410 and the positioning pin 420 are threadedly engaged, and the positioning pin 420 is connected and fixed to the locking structure 430. The locking structure 430 is a fixing ring, which is threadedly engaged with the outer wall of the positioning pin 420. Through the threaded engagement of the fixing sleeve 410 and the positioning pin 420, fine adjustment of the pin is achieved, combined with the rigid fixation position provided by the locking structure 430. This actively counteracts clearance deviations caused by long-term wear, ensuring that the top of the pin always precisely matches the hole in the battery bracket. The evenly distributed slide rods 610 and the return spring 620 in the positioning guide structure work together to ensure that the pin strictly maintains a vertical movement trajectory during extension and retraction. The sliding engagement between the slide rods 610 and the fixing plate 100 eliminates the risk of radial offset and ensures the coaxiality of the positioning pin and the bracket hole.

[0035] The retractable pin structure also includes a buffer structure, comprising a limiting stop 450 and a polyurethane flexible bushing 440. The limiting stop 450 is located at the bottom inner side of the fixed sleeve 410, and is used to limit the bottom of the polyurethane flexible bushing 440. The top of the polyurethane flexible bushing 440 abuts against the bottom of the positioning pin 420. Under the constraint of the limiting stop 450, the polyurethane flexible bushing 440 abuts against the bottom of the positioning pin 420, utilizing the elastic deformation characteristics of the material to absorb the instantaneous impact force during the riveting process, avoiding hard contact and stress transmission to precision components. This significantly reduces the interference of riveting vibration on positioning accuracy, while also reducing equipment structural noise. The flexible bushing isolates metal components from direct collision, and the spring system shares the dynamic load, jointly reducing the mechanical wear rate and extending the service life of the core components.

[0036] The positioning guide structure includes a return spring 620 and multiple slide rods 610. The multiple slide rods 610 are evenly arranged in the through hole. All slide rods 610 are slidably engaged with the fixed plate 100. The top of the slide rod 610 is threadedly connected to the bottom of the positioning pin 420. A limit block is provided at the bottom of the slide rod 610.

[0037] The top of the positioning pin 420 is provided with multiple guide slopes 500, which are evenly arranged circumferentially on the top of the positioning pin 420. The guide slopes 500 can mate with the holes of the battery bracket. The inner side of the riveting base 300 is connected to the upper end face of the fixing plate 100 through a threaded sleeve. The mounting plate 110 has an L-shaped cross-section, and the outer end of the mounting plate 110 is provided with two elongated holes. The elastic support mechanism includes a support plate 200 and multiple elastic components 210. The support plate 200 is connected to the upper end face of the fixing plate 100 through the multiple elastic components 210.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
