Description

Technical Field

[0001] This utility model relates to the field of battery casing testing technology, and in particular to a metal chip impact test fixture. Background Technology

[0002] After the battery casing is manufactured, the quantity and size of the metal shavings attached to it need to be inspected, so it is necessary to knock off the metal shavings first. Patent application number 201920103757.1 discloses a tooling for knocking off metal particles from the surface of a power battery casing. A guide rail fixing plate is vertically fixed on the base worktable, and two guide rails are vertically fixed on the guide rail fixing plate. A rear fixing plate is fixedly connected to the two guide rails. Two side plates are vertically fixed at both ends of the rear fixing plate. Two upper and lower fixing rods are connected between the two side plates. Multiple connecting blocks and multiple rotating blocks are fixedly installed on the upper and lower fixing rods. The upper end of the connecting block is U-shaped. Transparent invisible tape is laid into the groove inside the casing fixing block. The casing opening is inserted into the groove. By adjusting the air pressure, the cylinder pushes the rotating block, which drives the knocking rod and then the rubber hammer to knock the bottom of the casing, so that the metal shavings fall off and fall onto the transparent invisible tape. However, the cylinder movement is relatively slow and the knocking frequency is low, so the efficiency is low. Utility Model Content

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0016] Detailed implementation method: combined with Figure 1-3 As shown, a metal chip impact test fixture includes a base 1, on which a fixing sleeve 11 is provided. A battery casing can be inserted into the fixing sleeve 11. A vertical support 2 is provided on the rear side of the base 1. An impact assembly 5 is provided on the vertical support 2. The impact assembly 5 includes a frame 51. Two hanging rods 52 are provided on the bottom surface of the frame 51. The hanging rods 52 are in a vertical state. An impact block 55 is slidably connected to the two hanging rods 52. An impact hammer 551 is provided on the bottom surface of the impact block 55 and is located directly above the fixing sleeve 11. A column 552 is provided on the top surface of the impact block 55. A hammer is provided on the column 552. There is a crossbeam 553, and preferably two uprights 552 connected to both ends of the crossbeam 553 respectively. The crossbeam 553 is preferably cylindrical and rotatably connected to the uprights 552. The two ends of the central shaft 53 are rotatably connected to the two sides of the frame 51. The central shaft 53 is provided with a lever 532 that can push the crossbeam 553 upward and disengage it. The lever 532 corresponds to the position of the crossbeam 553, and the length of the lever 532 is greater than a certain distance between the central shaft 53 and the crossbeam 553. A large gear 531 is also provided at one end of the central shaft 53. A small gear that meshes with the large gear 531 is provided on the shaft of the motor 54 located on one side of the frame 51. The rotation of motor 54 drives the central shaft 53 to rotate. The paddle 532 pushes the crossbeam 553 upwards, causing the striking block 55 to rise. After the paddle 532 rotates a certain angle, the crossbeam 553 disengages from the paddle 532, and then the striking block 55 descends under the influence of gravity. The striking hammer 551 strikes the battery casing. As the central shaft 53 rotates continuously, the battery casing can be continuously struck. Two or more paddles 532 can be provided.

[0017] Furthermore, stepped holes 554 are provided on both sides of the striking block 55, and a through hole 555 with a smaller diameter is provided at the lower end of the stepped hole 554.

[0018] Furthermore, the boom 52 includes an upper boom section, the lower end of which has a lower boom section with a smaller diameter. The lower boom section is slidably connected to the through hole 555. A baffle plate with a diameter larger than the through hole 555 is located at the lower end of the lower boom section. The baffle plate is positioned below the striking block 55, preventing the striking block 55 from falling off the boom 52. A spring is installed between the bottom surface of the stepped hole 554 and the bottom surface of the upper boom section. The spring can increase the falling speed and striking force of the striking block 55.

[0019] Furthermore, a top plate 21 is provided on the top of the vertical support 2, and a screw 4 is rotatably connected to the top plate 21. A handwheel is provided on the top of the screw 4, and a threaded cylinder is provided on the top of the frame 51. The screw 4 is threadedly connected to the threaded cylinder. Multiple guide cylinders are provided on the top plate 21, and multiple guide posts are provided on the top of the frame 51, each of which is slidably connected to multiple guide cylinders. Rotating the handwheel can adjust the height of the striking component 5.

[0020] Furthermore, the striking hammer 551 is made of rubber.

[0021] Furthermore, a reinforcing rib 3 is provided at the corner where the vertical support part 2 is joined to the base 1, and a reinforcing rib 3 is provided at the corner where the vertical support part 2 is joined to the top plate 21, thereby improving the overall strength.

[0022] In use, first place the transparent invisible tape at the bottom of the fixing sleeve 11, then insert the battery casing with the opening facing into the fixing sleeve 11. Adjust the height of the striking component 5 so that the striking hammer 551 contacts the top surface of the battery casing. Then, continue to lower the striking component 5 by about one millimeter, and then start the motor 54 to strike the battery casing for one minute. After that, the battery casing can be removed, and the transparent invisible tape can be taken out so that the size and quantity of metal shavings on the tape can be inspected under a two-dimensional mirror. The motor 54 can rotate at a relatively high speed, resulting in a high striking frequency.

[0023] 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.
