[0001] The utility model relates to the technical field of cylindrical battery clamps, in particular to a clamp mechanism for large cylindrical batteries. Background Art

[0002] During the processing of large cylindrical batteries, in order to ensure the accuracy of subsequent welding and other processes, it is usually necessary to rely on fixtures to completely clamp and position the batteries before subsequent precise positioning processing can be carried out.

[0003] Existing large cylindrical battery positioning fixtures typically have positioning holes designed to match the battery. While this battery fixture provides accurate positioning, it is difficult to insert the battery into the positioning hole. Furthermore, each fixture can only accommodate one battery size, making it inconvenient to change battery types. Utility Model Content

[0004] The purpose of the utility model is to provide a clamp mechanism for large cylindrical batteries in view of the defects and shortcomings of the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The utility model describes a clamp mechanism for a large cylindrical battery, which includes a bottom frame with an open top and a clamping assembly arranged in the bottom frame; the clamping assembly is composed of a fixed block fixed inside the bottom frame and a dynamic positioning block arranged opposite to the fixed block; a second positioning concave is provided on the surface of the fixed block close to the dynamic positioning block; a first positioning concave is provided on the surface of the dynamic positioning block close to the fixed block; the dynamic positioning block is slidably connected to the inner cavity of the bottom frame; a lateral spring is connected between the dynamic positioning block and the bottom frame; and a draw hook is connected to the dynamic positioning block.

[0007] Furthermore, the width of the first positioning concave gradually decreases along the depth direction; the width of the second positioning concave gradually decreases along the depth direction.

[0008] Furthermore, the cross-sections of the first positioning concave and the second positioning concave are both trapezoidal in shape.

[0009] Furthermore, a partition is fixed in the middle of the bottom frame; a clamping module is composed of multiple clamping components arranged along the length direction of the partition; the number of the clamping modules is two; the two clamping modules are symmetrically arranged on both sides of the partition; and the fixing block is fixed on the partition.

[0010] Furthermore, the clamping module is composed of four clamping components evenly arranged along the length direction of the partition.

[0011] Further, the moving positioning blocks on the same clamping module are all fixed on the pull plate; the hook is fixed on the pull plate; the pull plate is slidably connected to the bottom frame.

[0012] Further, sliding plates are fixed on both sides of the pull plate; sliders are fixed on the sliding plates; guide rails slidably connected to the sliders are fixed on the bottom frame.

[0013] Further, side guide posts are fixed between the moving positioning blocks and the pull plate; side linear bearings slidably connected to the side guide posts are fixed on the bottom frame.

[0014] Further, the side spring is a cylindrical spring; the cylindrical spring is sleeved outside the side guide post.

[0016] After adopting the above structure, the beneficial effects of the present utility model are as follows: By pulling the hook through an external power mechanism, the moving positioning block overcomes the side spring and moves away from the fixed block; after the battery is placed between the moving positioning block and the fixed block, the pulling force of the hook is removed, and under the action of the side spring, the moving positioning block moves towards the fixed block, so that the battery is positioned in the cavity formed by the second positioning concave and the first positioning concave with the fixed block as a reference; in the normal state, due to the elastic force of the side spring, the pressure of the moving positioning block on the fixed block is maintained, realizing the clamping and fixing of the battery; in this structure, the battery is positioned by the opening and closing of the moving positioning block, and the moving positioning block automatically controls the distance from the fixed block according to the diameter of the battery, and this fixture can adapt to the clamping of various different specifications of batteries, facilitating the processing of battery type change.
