11. In one of the embodiments, the tool bar body further includes a first clamping handle, and the first clamping handle is used to fit the mounting groove of the tool bar holder.

12. In one of the embodiments, a support surface is provided on the side of the tool holder body corresponding to the position of the blade slot, and the support surface is a vertical surface; the side of the tool holder body corresponds to the blade The front end of the groove is provided with an inclined surface, and the inclined surface is inclined inwardly from the top to the bottom of the shank main body.

13. In one of the embodiments, the blade grinding fixture further includes a chamfering positioning seat for use with the cutter bar, the chamfering positioning seat is provided with a chamfering positioning portion, and the chamfering positioning The part is used to resist the blade.

14. In one of the embodiments, the chamfered positioning seat includes a seat body, and the seat body includes a second positioning bottom, a second positioning side, and a second clamping handle for adapting to the mounting groove of the tool bar holder Section, the second positioning bottom is used to

The bottom of the knife bar is tightly attached, the second positioning side portion is used for tightly contacting the side portion of the knife bar, and the second positioning bottom and the second positioning side portion enclose a positioning groove.

15. In one of the embodiments, the chamfer positioning seat further includes a chamfer stopper, the chamfer stopper is detachably connected to the seat body, and the chamfer positioning portion is provided on the chamfer Stoppers.

16. A blade grinder, including:

17. Feeding device, said feeding device comprising a frame, a power mechanism fixed to the frame, and a grinding wheel drivingly connected with the power mechanism;

18. Tool bar holder, the tool bar holder is provided with a mounting groove;

19. An image acquisition device and a display screen, the display screen is electrically connected to the image acquisition device; and

20. The blade grinding fixture.

21. In one of the embodiments, the feeding device further includes a feeding base, and the knife bar frame is fixed to the feeding base; the feeding base is provided with a first adjusting mechanism and a second adjusting mechanism, The first adjustment mechanism is used to drive the feed base to move in a first direction, and the second adjustment mechanism is used to drive the feed base to move in a second direction.

22. In one of the embodiments, the feeding device further includes a turntable, the turntable is rotatably provided on the feeding base, and the tool bar frame is fixed to the turntable.

23. In the above-mentioned blade grinding jig and blade grinder, the main body of the tool bar includes a first positioning bottom and a first positioning side, and the first positioning bottom and the first positioning side enclose an L-shaped blade groove. When installing the blade, place the blade in the blade slot, the bottom of the blade is close to the bottom of the first positioning, and the side of the blade is close to the side of the first positioning. The blade is positioned by the two reference parts of the first positioning bottom and the first positioning side, which effectively guarantees the consistency of the blade clamping. In addition, when installing the blade, the blade can be put into the blade slot from the side of the blade body, which can prevent the front end of the blade slot from being worn and the width of the front end of the blade slot increases, effectively avoiding angular positioning deviation after the blade is installed , After each grinding, there is no need to check and confirm the blade completely, which improves the efficiency of blade grinding. After the blade is placed in the blade slot, a fastener is used to lock and fix the pressure plate to the main body of the knife bar, so that the second end of the pressure plate is pressed against the blade. Compared with the movable pressing plate, the first end of the pressing plate is fixed to the main body of the knife bar. During the blade locking process, the pressing plate only moves up and down to compress the blade, effectively avoiding the problem of angular displacement of the blade caused by the rotation of the pressing plate This can ensure that the clamping accuracy of the blade is within a certain tolerance range, ensure the consistency of the blade clamping angle, and provide a strong guarantee for the angle of the knife after grinding. In this way, the blade grinding jig can improve the accuracy of the blade grinding angle, thereby increasing the pass rate of the blade grinding, and at the same time can improve the grinding efficiency.
