Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, specifically a multi-station clamping frame for battery testing. Background Technology

[0002] Battery testing is used to ensure the safety, performance, and lifespan of batteries. Testing requires clamping and securing the batteries, and multi-station clamps can simultaneously hold and test multiple battery samples. This type of clamp improves testing efficiency and data consistency.

[0003] The current clamping mechanism still has some shortcomings, such as only being able to clamp and fix the soft-pack battery from two sides:

[0004] To overcome the problem of low clamping efficiency of the clamping frame, the existing Chinese patent (publication number: CN222259412U) discloses a test clamp for soft-pack batteries. Its spring one and spring two buffer the battery to ensure battery safety. It can clamp the battery from four sides at the same time, which is more stable. Moreover, the two sets of clamping structures can push the battery to the middle position for clamping and fixing, which facilitates the test structure in the center to perform accurate testing, thus improving the testing efficiency of soft-pack batteries.

[0005] However, the current clamping frame still has some shortcomings. The clamping frame in the above document first pushes the battery to the designated position and then clamps and fixes it, which improves the clamping accuracy. However, the clamping frame is not convenient for fixing multiple batteries at the same time, which will also affect the efficiency of battery testing. It is also more troublesome to use. Therefore, the existing structure needs to be improved. Utility Model Content

[0010] Furthermore, the clamping mechanism includes a guide groove, which is formed on the side of the support plate. A guide block slides through the guide groove, and a fixing frame is fixed on the side of the guide block away from the support plate.

[0011] Furthermore, a threaded rod is rotatably inserted through the guide block and the guide groove, and the threaded rod and the guide block form a threaded connection. A large gear is fixed at the bottom of the threaded rod, and a small gear is meshed with the side of the large gear.

[0012] Furthermore, a telescopic rod is connected to the bottom of the pinion, and a second bevel gear is connected to the bottom end of the telescopic rod. The second bevel gear meshes with the side of the first bevel gear, and the second bevel gear, the first bevel gear, the telescopic rod, and the pinion are connected by a transmission.

[0013] Furthermore, the positioning mechanism includes a locking groove, which is symmetrically opened on the side of the sliding groove. A sliding block slides through the sliding groove, and the sliding block is rotatably connected to the side of the pinion away from the telescopic rod.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1, such as Figures 1-6The technical solution shown is provided by this utility model as follows: To solve the problem that the clamping frame is inconvenient for simultaneously clamping multiple workstations, thus affecting testing efficiency, a clamping mechanism is disclosed: including a base 1, with a support plate 2 symmetrically connected to the upper surface of the base 1, and two sets of fixing brackets 3 connected to the side of the support plate 2; a rotating groove 201 is opened inside the support plate 2, and a double-headed motor is installed at the center of the rotating groove 201, with rotating rods 202 connected to the two output ends of the double-headed motor, and a first bevel gear 203 fixed to the end of the rotating rod 202; a clamping mechanism for improving battery clamping efficiency is provided inside the rotating groove 201, and the clamping mechanism includes a guide groove 204, which is opened on the side of the support plate 2. A guide block 205 slides through the guide groove 204. A fixing bracket 3 is fixed to the side of the guide block 205 away from the support plate 2. A threaded rod 206 rotates through the guide block 205 and the guide groove 204. The threaded rod 206 and the guide block 205 form a threaded connection. A large gear 207 is fixed to the bottom of the threaded rod 206. A small gear 208 is meshed with the side of the large gear 207. A telescopic rod 209 is connected to the bottom of the small gear 208. A second bevel gear 210 is connected to the bottom of the telescopic rod 209. The second bevel gear 210 is meshed with the side of the first bevel gear 203. The second bevel gear 210, the first bevel gear 203, the telescopic rod 209 and the small gear 208 are connected for transmission.

[0031] When viewing the battery from the side, it needs to be moved between two fixed brackets 3. The fixed brackets 3 can clamp the battery. When the brackets clamp the battery, the dual-head motor is activated. When the dual-head motor is activated, the output end can drive the two rotating rods 202 to rotate. When the rotating rods 202 rotate, they can drive the first bevel gear 203 to rotate. The first bevel gear 203 rotates, which can drive the second bevel gear 210 to mesh and rotate. When the second bevel gear 210 meshes and rotates, it can drive the telescopic rod 209 to rotate. When the telescopic rod 209 rotates, it can rotate through the rotating groove 201. When the telescopic rod 209 rotates, it can drive the pinion 208 to rotate. When the pinion 208 rotates, it can... The large gear 207 is driven to mesh and rotate. When the large gear 207 meshes and rotates, it can drive the threaded rod 206 to rotate. When the threaded rod 206 rotates, it can rotate through the guide groove 204. When the threaded rod 206 rotates, it can drive the guide block 205 to mesh and rotate. When the guide block 205 meshes and rotates, it can slide through the guide groove 204. When the guide block 205 slides, it can drive the fixed frame 3 to move. When the fixed frame 3 moves, it can clamp and fix the battery with another fixed frame 3. Since the dual-head motor can drive the two rotating rods 202 to rotate at the same time, the clamping frame can fix and clamp two batteries at the same time, which improves the efficiency of the clamping frame.

[0032] Example 2, as follows Figure 1 , Figure 2 , Figure 5 and Figure 7 The present invention provides the following technical solution: In order to solve the problem that the clamping frame is inconvenient to independently clamp the battery, thus reducing the ease of use, a positioning mechanism is disclosed: A sliding groove 211 is provided through the top of the rotating groove 201. A positioning mechanism for independently operating the fixed frame 3 is provided inside the sliding groove 211. The positioning mechanism includes a locking groove 212, which is symmetrically opened on the side of the sliding groove 211. A sliding block 213 slides through the sliding groove 211. The sliding block 213 is rotatably connected to the side of the pinion 208 away from the telescopic rod 209. A telescopic groove 214 is provided through the side of the sliding block 213 near the locking groove 212. A push block 215 slides through the telescopic groove 214. A locking block 216 is fixed at the end of the push block 215. A spring is connected between the locking block 216 and the telescopic groove 214. The locking block 216 and the locking groove 212 are locked together.

[0033] Before the clamping bracket clamps the battery, pressing the push block 215 allows it to slide through the telescopic groove 214. When the push block 215 slides, it moves the engaging block 216. When the engaging block 216 moves, it slides through the engaging groove 212 and the telescopic groove 214. When the engaging block 216 slides, it compresses the spring inside the telescopic groove 214. After the engaging block 216 is pushed out of the engaging groove 212, it pushes the sliding block 213 upwards. When the sliding block 213 is pushed, it slides through the sliding groove 211. When the sliding block 213 slides, it pulls the pinion 208 to move. When the pinion 208 moves, it moves the telescopic rod 209. When the telescopic rod 209 moves, it can be stretched through the second bevel gear 210. When the telescopic rod 209 is stretched, the pinion 208 is inside the rotating groove 201. When the pinion 208 moves out of the side of the large gear 207, it can no longer maintain the meshing state. At this time, the sliding block 213 can drive the locking block 216 to slide to the side of another locking groove 212. Releasing the push block 215 can drive the locking block 216 to reset by the spring. When the locking block 216 is reset, it can engage and position with the other locking groove 212. When the locking block 216 is positioned, it can drive the sliding block 213 to be positioned. When the sliding block 213 is positioned, it can drive the pinion 208 to be positioned, thus keeping the pinion 208 and the large gear 207 separated. At this time, restarting the dual-head motor can only drive the fixing frame 3 on one side to squeeze and clamp the battery, so that the clamping frame can be adjusted according to the actual needs of the specified fixing frame 3 for operation and use, further improving the convenience of the clamping frame to fix the battery.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
