In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings.

Referring to fig. 2 and 3, a tool 10 for calibrating a pressing blade of a lamination machine is used for respectively connecting a lamination table 30 and a pressing blade 40, and includes a tool body 100 and a locking assembly 200, wherein a limiting groove 110 for accommodating the lamination table 30 is formed on a bottom surface of the tool body 100, a plurality of calibration grooves 120 are formed on a top surface of the tool body 100, the locking assembly 200 includes a plurality of locking bolts 210, the plurality of locking bolts 210 are divided into two groups, the two groups of locking bolts 210 are respectively screwed on two sides of the tool body 100, and each locking bolt 210 abuts against an outer side wall of the lamination table 30, so that parts of each pressing blade 40 are correspondingly and adaptively embedded in each calibration groove 120 one by one.

The tool body 100 is configured to be fastened to the lamination table 30, so that the pressing blade 40 can correct the position by using the tool body 100. Specifically, each locking bolt 210 is divided into two groups, one group of locking bolts 210 is screwed and fixed on one outer side wall of the tooling body 100, and the other group of locking bolts 210 is screwed and fixed on the other outer side wall of the tooling body 100. Thus, after the tooling body 100 is buckled on the lamination table 30, the top of the lamination table 30 is located in the limiting groove 110. At this time, by rotating the locking bolts 210, each locking bolt 210 can press and clamp two outer side walls of the lamination table 30, so that the tool body 100 and the lamination table 30 are fixed as a whole. In addition, the position of the tool body 100 relative to the lamination table 30 can be adjusted by adjusting the screwing distance of the locking bolt 210 relative to the tool body 100, so that the correcting groove 120 formed in the upper surface of the tool body 100 can better correct the position of the press blade 40. In this way, by machining a plurality of correction grooves 120 with a predetermined distance in advance on the upper surface of the tool body 100, the positions of the respective pressing blades 40 can be quickly corrected. In order to replace the traditional mode that uses slide caliper rule to carry out distance measurement to two adjacent stationary knifes 40 by the operating personnel, can make the correction operation more standard on the one hand to improve the correction degree of accuracy, utilize each correction groove 120 and each stationary knifes 40 looks adaptation screens moreover, convenient operation, thereby can improve stationary knifes 40's correction efficiency.

In one embodiment, the cross section of the limiting groove 110 is a U-shaped structure. It should be noted that, the limiting groove 110 is configured to be a U-shaped groove structure, so that the lamination table 30 can slide along the limiting groove 110 to adjust the relative position between the tool body 100 and the lamination table 30.

Referring to the drawings, in one embodiment, the width a of the limiting groove 110 is greater than the width B of the lamination stage 30. It should be noted that, since the size of the lamination table 30 is consistent with the size of the lamination cell, and the size of the lamination cell may be different according to the requirement of a customer, in order to enable the tool body 100 to be adapted to lamination tables 30 of different sizes and models, the width a of the limiting groove 110 is set to be greater than the width B of the lamination table 30, and the flexibility of the tool body 100 is improved by increasing the adjustment margin between the limiting groove 110 and the lamination table 30.

In one embodiment, the plurality of locking bolts 210 are equally distributed into two groups.

It should be noted that, the locking bolts 210 are divided into two groups, and the number of the locking bolts 210 in the two groups may be equal or different. For example, when the locking bolts 210 are provided with a plurality of base numbers, the number of the locking bolts 210 in two sets is not equal, and when the number of the locking bolts 210 is even, the number of the locking bolts 210 in two sets is equal, so that the two inner side walls of the limiting groove 110 can apply equal clamping force to the lamination table 30, and the stability of the tool body 10 relative to the lamination table 30 is improved.

In one embodiment, three locking bolts 210 are equidistantly disposed on any side wall of the tool body 100.

It should be noted that, three locking bolts 210 are respectively arranged on two sides of the tool body 100, so that the fixing strength of the tool body 100 is effectively improved. Further, in an embodiment, two locking bolts 210, or four locking bolts 210, etc. may be disposed on any one side surface of the tool body 100 according to actual requirements.

Further, referring to fig. 1, in an embodiment, four calibration slots 120 are formed, and the four calibration slots 120 are distributed in pairs and are respectively located at two ends of the tool body 100.

It should be noted that four pressing knives 40 are provided, and the four pressing knives 40 are used for pressing four corners of the diaphragm 21, so that the four calibration grooves 120 are correspondingly formed in the tool body 100, and the four pressing knives 40 can be correspondingly clamped in the four calibration grooves 120 one by one. The four calibration slots 120 are equally divided into two groups, and the two groups of calibration slots 120 are respectively located at two ends of the tooling body 100.

Further, referring to fig. 4, in an embodiment, a difference between the width C of the correction groove 120 and the width D of the pressing blade 40 is 0mm to 0.1mm.

The pressing blade 40 needs to be in clearance fit with the inner side wall of the correction groove 120, but in order to avoid an excessively large clearance between the pressing blade 40 and the correction groove 120, the difference between the width C of the correction groove 120 and the width D of the pressing blade 40 is set to 0mm to 0.1mm. For example, the difference between the width C and the width D may also be 0.02mm, or 0.04mm, or 0.06mm, or 0.08mm, etc.

Further, in an embodiment, the tool body 100 is a metal structure. For example, the tool body 100 is a tungsten steel structure, so that the tool body 100 has good wear resistance and excellent service life.

Further, referring to fig. 3, in an embodiment, the pressing blade 40 includes a base 41 and a pressing block 42, and the pressing block 42 is adjustably disposed on the base 41.

It should be noted that the pressing block 42 is fixedly mounted on the laminating machine through the base body 41, wherein the pressing block 42 and the base body 41 are detachably mounted, so that after the position of the pressing block 42 is limited by the calibration slot 120 on the tooling body 100, and then the pressing block 42 is fixedly mounted on the base body 41, the position calibration of the pressing blade 40 is completed.

Further, referring to fig. 3, in an embodiment, a waist-shaped hole 42a is formed on the pressing block 42, and the waist-shaped hole 42a passes through the screw 43 to fix the pressing block 42 on the seat 41.

It should be noted that, the waist-shaped hole 42a is formed in the pressing block 42, and then the screw 43 is screwed to the seat body 41 after the screw 43 passes through the waist-shaped hole 42a, so that the pressing block 42 is locked and fixed to the seat body 41. In one embodiment, two waist-shaped holes 42a are opened, wherein at least two screws 43 are disposed in each waist-shaped hole 42a, so that the structural strength between the pressing block 42 and the seat 41 can be improved.
