Description

Knife grain grinding peripheral device

Technical Field

The utility model relates to the technical field of automatic processing, in particular to a knife particle peripheral grinding device.

Background

The existing tool grain periphery grinding machine on the market mainly has two forms, the first is a rivet type, a rivet is passed through a central locking hole of a blade, then the rivet is tightened through a pull claw, a sharpened blade is fixed, and then the sharpened blade is ground; the other mode is to clamp the upper surface and the lower surface of the blade and then grind the blade, wherein the two modes comprise two rotatable rotating shafts B and C, the rotating shafts drive the blade to rotate and incline, and planes, arc surfaces, negative chamfers and the like on the periphery of the blade are ground to be used as the reference of the next machining process of the blade. The main disadvantages of the blind rivet type periphery grinding machine are: the range of use is limited. Because some blades do not have a central hole, the hole of some blades is not in the center, some blades are too small, the central hole is also small, a blind rivet cannot penetrate through the central hole, the blades are too large and difficult to clamp, and all types of blades to be processed are incomplete.

The manner of holding the cartridge against the upper and lower faces of the blade has the following disadvantages:

1, the design is too complex. Because the integration degree of the parts is not high, the design of the power part and the transmission part of the peripheral mill is very complicated, and the peripheral mill has high precision, so the requirement on manufacturing is very high, and the manufacturing and maintenance are very complicated.

2, the equipment is too bulky. The peripheral grinding machine size on the market is all very big for the lathe of other processes, and its leading cause is exactly that blade clamping device is too big to be caused, and this can lead to the transportation difficulty, occupies limited place resource, and is bulky, no matter there is certain difficulty in operation and maintenance, also can improve equipment cost by a wide margin in addition.

And 3, the equipment price is too high. The price of the equipment is high, and has various factors, for example, the equipment is large in size, and the required raw material spare and accessory parts are greatly improved, so that the price is increased; the design is complex, for example, the power head part uses worm and gear transmission or multi-gear transmission, certain difficulty exists in design, manufacture and assembly, a tip pressure head is pressed tightly by a self-made hydraulic cylinder, the design is complex, more subsystems matched by hydraulic clamping are used, oil leakage is easy, maintenance is not easy, and the like, so that the cost is increased; finally, the technology of peripheral grinding machines has been mastered mainly in foreign enterprises for many years, resulting in high equipment prices.

4, the main technologies of the machine tool are mastered by foreign equipment manufacturers. The cutter grinding machine has the advantages that both cutter manufacturing enterprises and cutter equipment manufacturing enterprises in China are very passive, the technical influence of foreign manufacturers cannot be eliminated even if the equipment can be manufactured, and due to high price, a large number of cutter manufacturing manufacturers cannot find the suitable equipment to grind the periphery of the blade, so that a large number of manual tool grinding machines still can grind the periphery of the blade in a surface-to-surface mode in China, and the product quality of the blade ground in the mode cannot be improved all the time.
