Examples

Referring to fig. 1 to fig. 3, the present embodiment provides a double-end fastening tool applied to a square-shell module 6, including a tool table 2, and a cell supporting plate 3 and an extrusion end arranged on the tool table 2, where the cell supporting plate 3 is used to form a supporting platform for placing the module 6 to be fastened; the extrusion ends comprise a first extrusion end 41 and a second extrusion end 42, and the first extrusion end 41 and the second extrusion end 42 are symmetrically arranged on two sides of the tool table; any extrusion end comprises a base 47 and a telescopic end, and the telescopic end can perform telescopic motion along the direction towards the cell supporting plate 3; and the battery cell supporting plate 3 can move relative to the tool table 2. Wherein, the tool table 2 is further provided with a cavity matched with the area of the cell supporting plate 3, and the cell supporting plate 3 is arranged in the cavity. The battery cell support plate structure is characterized by further comprising a jacking cylinder 5, wherein the jacking cylinder 5 is arranged on one side of the battery cell support plate 3 and is fixedly connected with the battery cell support plate 3; the jacking cylinder 5 is used for driving the electric core supporting plate 3 to move along the direction perpendicular to the horizontal plane where the tool table 2 is located. Referring to fig. 1 and fig. 2 again, the tooling table 2 in this embodiment is disposed on the working table 1, and the working table 1 is also provided with a cavity for matching the battery cell supporting plate 3 in the tooling table 2 to move up and down. Thus, the cell supporting plate 3 can move up and down relative to the workbench through the jacking cylinder 5.

The operation process of the embodiment is as follows: place end plate, the electric core of module 6 in frock platform 2 according to the production technology installation, inwards slide through the relative motion of first extrusion end 41 and second extrusion end 42, restrain module 6. And then, opening a downlink button of the jacking cylinder to enable the jacking cylinder 5 to drive the cell supporting plate 3 to synchronously downlink. Because the clearance is reserved on the cell supporting plate 3, the tooling table 2 and the working table surface 1, a space is reserved for the lower steel belt hoop 61. At this moment, the upper and lower steel belt hoops 61 can be sleeved in the module 6 at one time, the cylinder uplink button is opened, the cylinder drives the battery cell supporting plate 3 to synchronously uplink, the battery cell is dragged, the extrusion ends at the two ends slide outwards through the threaded screw rod 44, the module 6 is loosened, and the module 6 is taken out to complete the operation. Like this, when frock platform 2 was with 6 both ends anchor clamps of module, frock electricity core layer board 3 was down, and first steel band staple bolt 61 was from last down, and second steel band staple bolt 61 was from down up, once withheld tightly and overlaps twice steel band staple bolt 61. Need not restrict twice and the lasso, also reduced module 6 upset and invertd the action, reduced enterprise's risk and cost simultaneously.

In order to achieve the above effect, in the normal direction of the tool table 2, the projection area of the cavity is larger than that of the cell supporting plate 3. In the vertical direction from up to down or from down to up, the projection area of inner chamber is greater than the projection area of electric core layer board 3 promptly, and electric core layer board 3 can make things convenient for the up-and-down motion like this. And because the area of electric core layer board 3 generally is greater than the area of the module 6, even give the steel band staple bolt 61 that module 6 sheathes, also can get back to the initial station of frock platform 2. And, in order to guarantee good implementation effect, the geometric midpoint connecting lines of the first extrusion end, the cell supporting plate 3 and the second extrusion end are located on the same straight line.

In this embodiment, in order to solve the difficult problem of welding eccentricity due to inconsistent gap and tolerance under the condition of inconsistent bearing pressure of the battery cells at the two ends of the module 6, the base 47 is fixed on the tooling table 2, the telescopic end comprises a contact head and a telescopic component, the contact head is provided with the pressure sensor 43, the telescopic component comprises a threaded screw rod 44, and the threaded screw rod 44 is electrically connected with the pressure sensor 43; the moving direction of the telescopic end is parallel to the horizontal plane where the tooling table 2 is located. The fixing of initial position is guaranteed through base 47, and through the cooperation of screw lead screw 44 and pressure sensor 43, reach anticipated extrusion effect, guarantee that the electric core interval in the module 6 is unanimous, the skew condition that unilateral atress takes place can be avoided to the bi-polar atress like this. Meanwhile, in order to ensure the stability of stress and expansion, the expansion part further comprises a sliding rod 46 arranged on the contact and a sliding rod sleeve 45 arranged on a base 47, which are respectively arranged in parallel with the threaded screw 44. For assisting in positioning and securing the threaded screw 44. Referring to fig. 3 again, in the present embodiment, the sliding rods 46 and the sliding rod sleeves 45 are arranged in a matching manner at the telescopic ends, and there are four groups. And, in specific use, the tooling platform 2 further comprises a side limit end which is arranged on one side of the tooling platform 2 and is parallel to the tooling platform 2. For initial positioning and limiting of the module 6 during the execution of the process steps.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
