The utility model also comprises a contour block; the equal-height blocks are arranged between the upper cutter fixing plate and the lower cutter fixing plate.
The utility model also comprises a fixed rod rest, wherein the fixed rod rest is arranged on one side of the press, which is far away from the pressure head. The fixing rod leaning mountain press can prevent the device from turning over when the force is too large.
After the scheme is adopted, the upper knife edge to be ground is fixed on the upper knife fixing plate, the lower knife to be ground is fixed on the lower knife fixing plate, the corresponding reset spring is replaced, the upper knife and the lower knife to be ground are pressed downwards through the manual pressure rod, the pressure head contacts the upper knife fixing plate, so that interference fit of the upper knife and the lower knife to be ground (lubricating oil and grinding materials with a certain proportion are added before interference fit of the upper knife and the lower knife) is pushed, and different equal-height blocks are placed between the upper fixing plate and the lower fixing plate to control the depth of pressing. After the downward pressing force is removed by the pressure rod, the upper knife fixing plate is sprung up and reset by the reset spring, so that the contour degree of the upper knife edge and the lower knife edge can be anastomosed and reasonably clearance can be realized by reciprocating repetition, and the grinding precision is high, and the operation is convenient.
The utility model will be further described with reference to the drawings and the specific examples.

Detailed Description
As shown in fig. 1-4, the utility model relates to a grinding device for a laminated battery die knife edge, which comprises an upper knife fixing plate 1, a lower knife fixing plate 2, four return springs 3, two spring seats 4, a fixing rod leaning mountain 5 and an equal-height block 6.
The lower knife fixing plate 2 is arranged on a base 105 of the press 10, the bottom surface of the upper knife fixing plate 1 is connected with the top surface of the lower knife fixing plate 2 through four return springs 3, and the fixing rod leaning against the mountain 5 is arranged on the base 10 of one side of the press 10 far away from the press head 101. The fixing rod leaning hill 5 can prevent the side turning of the press 10 when the force is too large, and the equal-height block 6 is placed between the upper cutter fixing plate 1 and the lower cutter fixing plate 2 and used for limiting the pressing depth of the upper cutter fixing plate 1.
The middle part of the spring seat 4 is provided with a middle hole 41 penetrating the whole length, the upper end of one spring seat 4 is fixed on the bottom surface of the upper cutter fixing plate 1, the lower end of the other spring seat 4 is fixed on the top surface of the upper cutter fixing plate 2, and the two ends of the return spring 3 are respectively movably sleeved in the middle holes 41 of the two spring seats 4.
The working principle of the utility model is as follows:
1. the upper knife edge to be ground is fixed on the upper knife fixing plate 1, the lower knife to be ground is fixed on the lower knife fixing plate 2, the corresponding reset spring 3 is replaced, the pressure head 101 is pressed downwards through the manual pressure rod 102 to contact the upper knife fixing plate 1, so that the interference fit of the upper knife to be ground and the lower knife (a certain proportion of lubricating oil and grinding materials are added before the interference fit of the upper knife and the lower knife) is pushed, and different contour blocks 6 are placed between the upper knife fixing plate 1 and the lower knife fixing plate 2 to control the pressing depth. When the pressure rod 102 removes the downward pressing force, the upper knife fixing plate 1 is sprung up and reset by the reset spring 3, so that the contour degree of the upper knife edge and the lower knife edge can be matched and a reasonable gap can be realized by repeated reciprocation.
2. When the pressure required for the large area of the edge of the grinding is large, the manual pressure rod 102 can be sleeved with a force-applying rod 103; the height of the knife edge of the lapping is longer or shorter, and the head slider 104 can be adjusted to meet the desired height.
3. The utility model is applied to a traditional press machine and is modified according to the condition of manual crow bar reset after grinding the edge. According to the area of the grinding edge, the required reset spring force is calculated, and the automatic reset after the continuous pressing of the edges with different sizes can be realized by replacing the corresponding springs.
Other description:
