[0025] The present invention is further described in detail below with reference to the embodiments.

[0026] Specific embodiments of the battery core bead cutting and positioning tool provided by the utility model:

[0027] See also Figure 1-4 In this embodiment, the pultruded cell bead blank 13 is cut after pultrusion to a length greater than the cell bead. The bead blank 13 has a rectangular cross-section and two pultrusion holes. A section is precisely cut off at each end of the bead blank 13 to ensure accurate length and end quality. Front grooves 132 are then cut on the front of each end, and back grooves 133 are cut on the back of one end. Prior to the cutting process, through holes 131 for positioning are machined on both ends of the bead blank 13.

[0028] The battery cell bead cutting and positioning tool in this embodiment includes a base plate 1. Four lifting rings 12 are provided on the upper edge of the base plate 1 to facilitate lifting the positioning tool to a CNC machining center for installation. Several stepped mounting holes are provided on the edge of the base plate 1 to facilitate bolt installation on the CNC machining center.

[0029] The upper side of the base plate 1 is provided with a plurality of mutually parallel blank receiving grooves 2 for accommodating the bead blank 13. In this embodiment, there are eight blank receiving grooves 2, divided into two groups of four evenly spaced. The spacing between the two groups of blank receiving grooves 2 is greater than the spacing between adjacent blank receiving grooves 2 in the same group. The width of the blank receiving groove 2 is adapted to the bead blank 13, and the depth is less than the thickness of the bead blank 13. When the bead blank 13 is placed in the blank receiving groove 2, the blank receiving groove 2 can limit the sides and bottom of the bead blank 13.

[0030] The two ends of the blank accommodating groove 2 extend to the end surfaces of the base plate 1 respectively, so that the blank accommodating groove 2 forms a through groove, which makes it easy to quickly remove the end waste of the cut layer blank 13 from the end of the blank accommodating groove 2 of the base plate 1.

[0031] One end of the blank receiving groove 2 is provided with a positioning pin 3 that extends into the through hole 131 at the end of the bead blank 13. The positioning pin 3 is set in the end of the blank receiving groove 2 where the back groove 133 of the bead blank 13 needs to be processed to ensure the stability of the bead blank 13 at this end during the processing of the back groove 133. After a section is cut off at both ends of the bead blank 13 and the front groove 132 is processed using a small tool; the bead blank 13 is turned over, and the positioning pin 3 is again inserted into the through hole 131 at the end of the bead blank 13, and the back groove 133 is then cut.

[0032] The upper sides of both ends of the base plate 1 are provided with limit assemblies for limiting the upper side of the layering blank 13; the limit assemblies include a pressure rod 4 and several rotating pressing cylinders 5 that press the pressure rod 4 down; the pressure rod 4 is placed vertically on the upper side of the ends of all layering blanks 13, and the rotating pressing cylinder 5 is installed on the upper side of the base plate 1.

[0033] The lower side of the pressure rod 4 is provided with a rubber pad 10 that contacts the layering blank 13, and the rubber pad 10 can protect the surface of the layering blank 13; two parallel pressure rods 4 are placed at both ends of the base plate 1; each pressure rod 4 is correspondingly provided with three rotary pressing cylinders 5, and both ends of the base plate 1 have six rotary pressing cylinders 5, four of the six rotary pressing cylinders 5 are right-handed and two are left-handed, so as to avoid the rotary pressing cylinder 5 at the edge of the base plate 1 from exceeding the range of movement of the base plate 1; the six rotary pressing cylinders 5 at the same end of the base plate 1 are grouped in pairs, for a total of three groups, and the three groups of rotary pressing cylinders 5 are respectively located between and on both sides of the two groups of blank accommodating grooves 2; a U-shaped rod seat 7 for limiting the end of the pressure rod 4 is provided on the upper side of the base plate 1, and the rod seat 7 limits the pressure rod 4 on both sides in the lateral direction.

[0034] The rotary pressing cylinders 5 operate synchronously, and a cylinder reversing switch 8 is provided on the base plate 1 to control the operation of the rotary pressing cylinders 5. The cylinder reversing switch 8 is a manual, two-position, three-way reversing valve. One end is connected to the air source via an air pipe, and the other two ends are connected to the rod chamber and rodless chamber of all rotary pressing cylinders 5 via air pipes. Manual operation of the cylinder reversing switch 8 reverses the airflow, achieving synchronous compression and release of all rotary pressing cylinders 5. The rotary pressing cylinders 5 are equipped with a pressure block 9 that contacts the pressure rod 4. The pressure block 9 is made of nylon.

[0035] A cutting groove 6 is provided on the upper side of the end of the base plate 1, and there are four cutting grooves 6. Each cutting groove 6 is located at one end of a group of blank accommodating grooves 2. The cutting groove 6 is vertically connected to the blank accommodating groove 2, and the cutting groove 6 is located between the two pressure rods 4; the depth of the cutting groove 6 is greater than the depth of the blank accommodating groove 2; the cutting mechanism of the CNC machining center cuts off a section of the same end of a group of press strip blanks 13 in the blank accommodating groove 2 along the cutting groove 6 in sequence at the position corresponding to the cutting groove 6. The existence of the cutting groove 6 will not cause interference between the base plate 1 and the cutting mechanism, thereby protecting the cutting mechanism.

[0036] The upper side of the base plate 1 is connected to a number of auxiliary pressure plates 11 by bolts. There are eight auxiliary pressure plates 11, four at each end of the base plate 1. They are closer to the middle relative to the pressure rod 4, which improves the stability of the positioning of the bead blank 13. The auxiliary pressure plates 11 are located on the upper side of two adjacent bead blanks 13; the auxiliary pressure plates 11 are pressed against the upper side of the bead blank 13 by bolts, and a soft pad can be set on the lower side of the auxiliary pressure plates 11 to protect the bead blank 13; the auxiliary pressure plates 11 are sleeved on the outside of the bolts, the lower end of the bolts is connected to the base plate 1, and the upper end of the bolts is threadedly connected to a nut that limits the auxiliary pressure plates 11. The width of the auxiliary pressure plates 11 is smaller than the spacing between adjacent bead blanks 13 in the same group of blank slots 2. When the auxiliary pressure plates 11 are no longer needed for auxiliary positioning, the auxiliary pressure plates 11 can be rotated to be parallel to the bead blank 13. In this way, the auxiliary pressure plates 11 will not interfere with the placement and removal of the bead blanks 13, making the loading and unloading of the bead blanks 13 convenient.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments without inventive effort, or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
