Abstract

The utility model relates to a rolling cutter for a zinc ring for a fitting at the end part of a DC (Direct Current) insulator, and effectively solves the problems that the zinc leakage is generated by damaging a zinc layer on the surface of a fitting rod part by mistake in the process that the zinc ring is turned by a lathe, the production efficiency is low, the appearance of the zinc ring is poor during manual zinc filing, and the like. The technical scheme adopted to solve the problems is as follows: the rolling cutter comprises a shank, wherein a through hole is formed in the shank in the left and right direction, and a shaft sleeve is arranged in the through hole; a pin shaft is arranged in the shaft sleeve in a penetrating way, and a lug boss fit to the right side surface of the shank is arranged on the pin shaft; a screw cap is sleeved at the left end of the pin shaft, and the pin shaft and the shank are fixed together through the lug boss and the screw cap; and a thrust bearing, a shim and a radial bearing are sequentially sleeved on the pin shaft at the right side of the lug boss, and a roller wheel is sleeved on the radial bearing. The rolling cutter provided by the utility model has the advantages of novel and unique structure, simple structure, better completion of zinc filing production, and strong practicality.

Description

The end of DC insulator gold utensil zinc ring rolls the stone roller cutter

One, technical field

The utility model relates to cutter, and particularly a kind of the end of DC insulator gold utensil zinc ring rolls the stone roller cutter.

Two, background technology

At present, the zinc ring casting process that adopts in the industry is because zinc liquid cast temperature, the factor of workpiece temperature and hot operation condition inevitably produces the phenomenon that the slit appears in zinc ring and gold utensil bar section, the modes of the artificial file of Lathe turning tool processing combination zinc that adopt are processed more in the industry, lathe tool processing is beated owing to twice clamping can produce gold utensil bar section, accidentally injure the easy like this part of gold utensil bar section surface zinc layer of causing, produce gold utensil and leak the zinc phenomenon, gold utensil surface leakage zinc must return plating, again the zinc ring of casting, therefore increased rework cost, artificial file zinc production efficiency is low, and it is not attractive in appearance to rub the zinc ring that comes.

Three, summary of the invention

For above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just provides a kind of the end of DC insulator gold utensil zinc ring and rolls the stone roller cutter, has effectively solved in the lathe Che Xinhuan process to accidentally injure the leakage zinc that gold utensil bar section surface zinc layer produces and manually to file the problems such as the low and zinc ring outward appearance of zinc production efficiency is bad.

The technical scheme of its solution is, comprise handle of a knife, the through hole that left and right directions is arranged on the handle of a knife, be provided with axle sleeve in the through hole, be equipped with bearing pin in the axle sleeve, the boss that fits with the handle of a knife right flank is arranged on the bearing pin, the bearing pin left end is set with nut, bearing pin is fixed together through boss and nut and handle of a knife, is set with successively thrust bearing, shim liner and radial bearing on the bearing pin on boss right side, is set with roller on the radial bearing.

The utility model novel structure is unique, and is simple in structure, can better finish the production of file zinc, practical.

Fig. 3 is the utility model pin shaft structure schematic diagram.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Provided by Fig. 1 to Fig. 3, the utility model comprises handle of a knife, the through hole that left and right directions is arranged on the handle of a knife 1, be provided with axle sleeve 2 in the through hole, be equipped with bearing pin 3 in the axle sleeve 2, the boss that fits with handle of a knife 1 right flank is arranged on the bearing pin 3, bearing pin 3 left ends are set with nut 4, bearing pin 3 is fixed together with handle of a knife 1 through boss and nut 4, is set with successively thrust bearing 5, shim liner 6 and radial bearing 7 on the bearing pin 3 on boss right side, is set with roller 8 on the radial bearing 7.

Be set with plain cushion 9 on the bearing pin 3 between said nut 4 and the handle of a knife 1.

Said shim liner 6 right circles circumferential edges have projection, and bossing contacts with the outer ring of radial bearing 7, have so just guaranteed can also select normally dress when roller 8 is subject to axial force and radial load at the same time.

Said roller 8 is made by metal material.

When the utility model used, on the chuck of lathe, handle of a knife 1 was fixed on the knife rest with piece-holder, the center of the centrally aligned excircle of workpiece of roller 8 during use, workpiece rotating passes to the roller 8 that contacts with workpiece by frictional force, driving radial bearing 7 rotates, if axially loaded is excessive, the process continuous and stable of stone roller is rolled in thrust bearing 5 stressed rotations, zinc ring matter is soft, zinc ring and gold utensil bar section are stressed, and evenly outward appearance is highly polished, and zinc ring and gold utensil bar section cylindrical are closely linked behind the roller.
