Abstract

The utility model provides tooling equipment for a chamber cylinder of a vertical drill press, comprising a foundation plate, a supporting sleeve and locating pieces, wherein, the foundation plate, the supporting sleeve and the locating pieces are installed on a vertical drill press. The utility model is used for repairing cylinder holes of a light car, a motorcycle, etc., and the utility model can be processed in a small amount; the whole accuracy requirements of the cylinder holes can be accuracy requirement guaranteed, and a cylinder borer is not used by a chamber cylinder. The manufacturing cost of the utility model is low; at the same time, the complete operation of the drill press is not affected, and the utility model brings large technical and economical effects to a car industry, a motorcycle industry and other machinery industries.

Description

Upright drill boring cylinder frock

The utility model relates to the used frock of boring cylinder.

At present, the processing in the cylinder cylinder hole of automobile and motorcycle is all carried out on cylinder boring machine, there is following deficiency in the processing cylinder hole on the cylinder boring machine, because the cylinder boring machine main shaft rotates on bearing, and bearing has the out-of-roundness error, and adding when using has uneven wearing and tearing again, and the original out-of-roundness error of bearing is increased more, the out-of-roundness error of like this, processed casing bore also can increase.Therefore the processing cylinder hole can't guarantee definitely that the form error in cylinder hole is no more than its form tolerance value on cylinder boring machine; In addition, boring machine cost height, general semiworks, self-employed worker cannot afford, and bring inconvenience to the user, the damage repair of some small-sized cylinders especially, the user does not want to spend big price to go to repair with boring machine.

The purpose of this utility model provides a kind of simple frock and cutter of processing small-sized cylinder cylinder hole on upright drill, makes its specification requirement that can guarantee the cylinder hole, and is economical again convenient, especially is convenient to the reparation of small-sized casing bore.

The technical solution of the utility model is, the frock of design one bore hole on upright drill, at first the bevel gear under the Drilling machines bench is removed, change the circumference cover with holes that the not overslaugh knife bar littler than bevel gear passes through, on the upright drill workbench, adorn one with the soleplate and the adjusting pad of main axis rotation central vertical, in the soleplate centre bore, adorn one with the splicing sleeve of main axis rotation centres with prevent the locating piece that splicing sleeve rotates.

After adopting technique scheme, at first carry out half right boring hole with common boring cutter, because soleplate and main axis rotation central vertical, splicing sleeve center and main axis rotation centres, Jia Gong cylinder hole can guarantee positional precision and vertical precision like this, carries out fine finishining with floating boring tool again, and processed like this cylinder bore dia can reach very desirable precision, simultaneously form accuracy, fineness are also fine, can reach specification requirement; While processing cylinder hole on vertical drill, than processing cylinder hole economy on engine lathe, milling machine, boring machine, also grasped by people easily, in addition, after vertical drill changed cylinder boring machine, drilling machine function and cylinder boring machine function were neglected neither, must be the frock complete removal in processing cylinder hole and will finish its operate as normal after processing the cylinder hole on other lathe, together, reduced economic benefit when so just expending.And vertical drill does not exist this together to inscribe, and can realize the processing in cylinder hole and repair universalness, can promote the development of economic technology better.

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

Accompanying drawing is the front view of upright drill boring cylinder frock of the present utility model.

Among the figure, soleplate 1 usefulness alignment pin 2 is connected with the workbench 3 of upright drill, the centre bore 10 of workbench will expand the big 10-5mm of diameter than Mohs square bar to, adorn a circumference with holes cover 12 littler on the leading screw under the workbench than bevel gear, in order to guarantee that soleplate becomes vertical with the drill press spindle pivot, in position fill up an adjusting pad 4, in the soleplate centre bore, place splicing sleeve 5, splicing sleeve and soleplate are for tightly being slidingly matched, with the column part of Mohs knife bar for gently being slidingly matched, the splicing sleeve end face is provided with 4 slotted holes, in order to leak iron filings, for preventing that splicing sleeve from rotating, adorn a positioning block 6, block 7 is equipped with in the splicing sleeve lower end, to prevent that splicing sleeve from falling, block 7 usefulness screws are connected with basic blocks, and the Mohs knife bar 9 with common boring cutter piece 8 is housed in the spindle taper hole of upright drill, and shown in the double dot dash line is processed cylinder 11.If the waste vapour cylinder, the useless greatly casing bore of boring at first, and be pressed into the self-control cylinder sleeve, under the motionless situation of workpiece cylinder body, half right boring cylinder sleeve bore, the workpiece cylinder body is motionless then, again with the cutter right boring cylinder sleeve bore that floats.

Claims

1, a kind of upright drill boring cylinder frock, it is characterized in that: the bevel gear under the Drilling machines bench is removed, change the circumference cover with holes that the not overslaugh knife bar littler than bevel gear passes through, on the upright drill workbench, adorn one with the soleplate and the adjusting pad of main axis rotation central vertical, in the soleplate centre bore, adorn one with the splicing sleeve of main axis rotation centres with prevent the locating piece that splicing sleeve rotates.
