Description

Technical Field

[0001] This utility model belongs to the field of storage battery production technology, and in particular relates to a device for testing the strength of lead-acid battery plates. Background Technology

[0002] The starting performance and lifespan of a battery are important indicators. The plates are composed of grids and active materials. After a curing process, the grids and active materials are bonded together. The bonding strength of the plates determines their performance. Therefore, the strength of the plates needs to be tested during the production process.

[0003] For example, Chinese utility model CN222258658U discloses a tooling for testing the drop strength of an electrode plate. During testing, the cylinder pedal is pressed by foot, and the cylinder assembly controls the screw to retract. The support plates on both sides open synchronously. After the electrode plate undergoes free fall, it contacts the test platform. The plate is then manually picked up and weighed. The mechanical strength of the electrode plate is evaluated based on the weight loss ratio before and after the drop.

[0004] However, existing detection devices require cylinder operation, which necessitates the installation of matching electric switches and compressed air sources. This limits the use of the detection devices and increases operating costs, resulting in poor flexibility and adaptability of existing detection devices. Utility Model Content

[0005] The purpose of this invention is to provide a lead-acid battery plate strength testing device. By stepping on a foot pedal, two rotating shafts are driven to rotate synchronously, causing the two support plates to rotate from a horizontal downward position to a vertical position, thereby releasing the plates. This solves the problems of poor flexibility and adaptability of existing testing devices.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a lead-acid battery plate strength testing device, comprising a test platform and a support rod. The support rod is a hollow tubular structure, with a housing fixedly connected to its upper end. Two rotating shafts are rotatably connected to the side wall of the housing, each shaft being fixedly connected to a support plate. The two support plates are arranged opposite to each other. The other end of each shaft extends into the housing and is fixedly connected to a driven gear. A pull rod is fitted inside the support rod, and a straight groove is formed on the lower side wall of the support rod. The pull rod is fixedly connected to a connecting column that fits with the straight groove with a clearance fit. A foot pedal is fixedly connected to the connecting post; the upper end of the pull rod extends into the box body and is connected to a mounting plate. A rack that meshes with the driven gear is fixedly connected to the upper surface of the mounting plate. Several guide rods are fixedly connected to the mounting plate. The guide rods are movably inserted and connected to the bottom wall of the box body, and the guide rods are fitted with compression springs. By stepping on the foot pedal, the mounting plate is pulled down by the pull rod. Through the meshing of the rack and the driven gear, the two rotating shafts are driven to rotate synchronously, so that the two support plates rotate synchronously from horizontal downwards to a vertical state, thereby releasing the electrode plates.

[0008] As a preferred embodiment of this utility model, the support rod includes an outer tube fixedly connected to the test bench, an inner tube sleeved on the outer tube, and a box body connected to the inner tube. The height of the box body can be adjusted by adjusting the axial position of the inner tube.

[0009] As a preferred embodiment of this utility model, the pull rod includes a screw and a sleeve. The sleeve is a tubular structure and has an internal thread on its inner wall that mates with the screw. By rotating the screw, the overall length of the pull rod can be adjusted.

[0010] As a preferred embodiment of this utility model, the mounting plate is fixedly connected to a connecting sleeve, and a locking screw is threadedly connected to the side wall of the connecting sleeve. The upper end of the screw passes through the mounting plate and is clearance-fitted with the connecting sleeve. The position of the screw is fixed by the locking screw.

[0011] As a preferred embodiment of this utility model, the screw has an annular groove, and the end of the locking screw is inserted into the annular groove.

[0012] As a preferred embodiment of this utility model, the upper end face of the screw is provided with an internal hexagonal hole.

[0013] As a preferred technical solution of this utility model, two opposing C-shaped baffles are fixedly connected to the outer wall of the box. The two C-shaped baffles are respectively located above the two support plates and are used to limit the horizontal position of the electrode plates placed on the two support plates.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a housing to rotatably connect two rotating shafts. One end of each shaft is connected to a support plate, and the other end extends into the housing, each connected to a driven gear. Stepping on the foot pedal pulls down the mounting plate using a lever. Through the meshing of the rack and pinion, the two shafts rotate synchronously, causing the two support plates to rotate from a horizontal downward position to a vertical position, thus releasing the electrode plate. This eliminates the need for pneumatic or electric drive, allowing the electrode plate strength testing device to be used in any location, reducing overall operating costs, and effectively improving overall flexibility and adaptability.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figures 1-3 As shown, this utility model is a lead-acid battery plate strength testing device, including a test platform 1 and a support rod 2. The support rod 2 is a hollow tubular structure. The lower end of the support rod 2 is connected and fixed to the test platform 1, and the upper end is fixedly connected to a box 3. The bottom wall of the box 3 has an insertion hole that communicates with the support rod 2.

[0032] like Figures 4-6 As shown, the side wall of the box 3 is rotatably connected to two rotating shafts 301. Both rotating shafts 301 are welded or screwed to fix a support plate 302. The two support plates 302 are arranged opposite to each other. The other end of the rotating shaft 301 extends into the box 3 and is fixedly connected to a driven gear 303.

[0033] A pull rod 4 is fitted inside the support rod 2, and a vertically arranged straight groove 201 is opened on the side wall at the lower end of the support rod 2. A connecting post 401 that is clearance-fitted with the straight groove 201 is fixedly connected to the pull rod 4. The pull rod 4 has a threaded hole, and the connecting post 401 is connected to the threaded hole by a thread. A foot pedal 402 is fixedly connected to one end of the connecting post 401 located on the outside of the support rod 2.

[0034] like Figure 7 and 8 As shown, the upper end of the pull rod 4 passes through the insertion hole into the box 3 and is connected to the mounting plate 5. The upper surface of the mounting plate 5 is fixedly connected to the rack 501 that meshes with the driven gear 303. The two racks 501 are located between the two driven gears 303.

[0035] The mounting plate 5 is welded with two guide rods 502, which can also be hollow tubes to reduce the overall weight. The bottom wall of the box 3 has through holes that fit with the guide rods 502 with clearance. The guide rods 502 are movably inserted and connected to the through holes in the bottom wall of the box 3, and a compression spring 503 is sleeved on the guide rods 502. The compression spring 503 is located between the bottom wall of the box 3 and the mounting plate 5.

[0036] Before testing, the electrode plate to be tested is placed on two trays 302. The outer wall of the box body 3 is connected by two opposing C-shaped baffles 101 by screws. The two C-shaped baffles 101 are located above the two trays 302, so that the two C-shaped baffles 101 are respectively clamped at both ends of the electrode plate, which is used to limit the horizontal position of the electrode plate placed on the two trays 302.

[0037] During testing, by stepping on the foot pedal 402, the mounting plate 5 is pulled down using the pull rod 4. Through the meshing of the rack 501 and the driven gear 303, the two rotating shafts 301 are driven to rotate synchronously. One rotating shaft 301 rotates counterclockwise and the other rotating clockwise, thereby causing the two support plates 302 to rotate from horizontal downwards to a vertical position, thus releasing the electrode plates and allowing them to fall freely to achieve strength testing.

[0038] After the electrode plate is released, release the foot pedal 402. Under the rebound action of the compression spring 503, push the mounting plate 5 upward, causing the rack 501 to drive the driven gear 303 to rotate in the opposite direction. This causes the rotating shaft 301 to drive the support plate 302 to rotate and reset, and pull the lever 4 to move upward and reset, thus facilitating the next test.

[0039] This application allows the electrode plate to be released by stepping on the foot pedal 402, eliminating the need for pneumatic or electric drive via compressed air. This enables the electrode plate strength testing device to be used in any location, reducing overall operating costs and effectively improving overall flexibility and adaptability.

[0040] Example 2

[0041] Based on Example 1, such as Figure 4 , 5As shown in Figure 8, the support rod 2 includes an outer tube 21 fixedly connected to the test bench 1. An inner tube 22 is fitted onto the outer tube 21. The housing 3 is connected to the upper end of the inner tube 22. The outer tube 21 and the inner tube 22 can be axially extended and retracted to adjust the height of the housing 3, thus facilitating adaptation to the detection height of different electrode plates and improving overall adaptability. Simultaneously, a hand-tightening screw is threaded onto the outer tube 21, which locks and fixes the inner tube 22, ensuring that the adjusted outer tube 21 and inner tube 22 are relatively fixed.

[0042] Meanwhile, the pull rod 4 includes a screw 41 and a sleeve 42. The sleeve 42 is a tubular structure and its inner wall is provided with an internal thread that mates with the screw 41. By rotating the screw 41, the overall length of the pull rod 4 can be adjusted.

[0043] Specifically, a connecting sleeve 504 is welded to the mounting plate 5, and a through hole coaxially arranged with the connecting sleeve 504 is provided on the mounting plate 5. A locking screw 505 is threaded to the side wall of the connecting sleeve 504. The upper end of the screw 41 passes through the through hole and penetrates the mounting plate 5, and is clearance-fitted with the connecting sleeve 504. The locking screw 505 is used to fix the position of the screw 41.

[0044] When adjusting the axial extension and retraction of the outer tube 21 and the inner tube 22, the screw 41 is rotated to move axially, so that the overall length of the pull rod 4 is adapted to the length of the adjusted support rod 2. At the same time, the screw 41 has an annular groove 403, and the end of the locking screw 505 is inserted into the annular groove 403 to limit the axial position of the screw 41. When it is necessary to rotate the screw 41 for adjustment, simply loosen the locking screw 505. At this time, the locking screw 505 is still inserted in the annular groove 403, which still limits the relative position of the screw 41 and the mounting plate 5. Thus, the screw 41 can be rotated, and the length of the pull rod 4 can be adjusted without disassembling the mounting plate 5.

[0045] In a preferred embodiment, the upper end face of the screw 41 is provided with an internal hexagonal hole 404, which facilitates the rotation of the screw 41 using a hexagonal wrench, further improving the convenience of adjustment. Furthermore, the screw 41, sleeve 42, mounting plate 5, and rack 501 are all made of nylon material, which not only reduces processing difficulty but also reduces overall weight, thus improving ease of use.
