Abstract

The utility model relates to a vertical-horizontal boring machine which is a boring process metal cutting machine for overhauling the components of the chassis and motors of automobiles and tractors. The utility model comprises a base, an upright post, a boring head which can change cutting directions at vertical and horizontal directions, a worktable which can move forwards on a guide rail, a supporting seat for horizontal boring, etc. The utility model can bore vertically and horizontally as well as hone under the two operating states; on the basis of the premise of guarantee various boring technical requirements, exchanged with different clamps and tools, one vertical-horizontal boring machine can complete total work which JB/Z204-83 series boring machines can complete (including in-line type and V-shaped motors).

Description

Vertical-horizontal boring machine

The utility model is the Metal Cutting Machine Tool for its parts bore hole processing of overhaul of the chassis of automobile, tractor and engine.

Requirement by JB/Z204-83 " automobile, tractor are repaired special boring mill series type spectrum ".In automobile, the tractor repair work, the hole boring processing of various parts needs 9 kinds of 12 various special boring mills approximately.The utility model provides the boring machine of a kind Metal Cutting Machine Tool, and it can stand the boring boring of also can crouching.And can under vertical and horizontal state, carry out honing.Guaranteeing to change different anchor clamps and frock under every bore hole technical request, a playscript with stage directions lathe can be finished whole work that JB/Z204-83 boring machine series can be finished.

The purpose that the utility model proposes provides a kind of horizontal-vertical double-purpose boring machine, can reduce the engine overhaul work mesopore process equipment quantity that automobile, tractor chassis and in-line arrangement and V-type are arranged in a large number, thereby reduce equipment initialization expense significantly, all kinds hole processing technology quality and productivity ratio have been improved, and improved every utility factor of this repairing lathe, reduced parts bore hole processing cost.

The purpose of this utility model is achieved in that

The horizontal-vertical double-purpose boring machine is mainly by constitute (Fig. 1) as lower member

1, base 2, movable workbench gearbox 3, workbench lower slider 4, workbench 5, boring head 6, collar bush locking chuck 7, main spindle box 8, travel switch 9, main spindle box clamping lever 10, collar bush lifting handle 11, travel switch rams 12, collar bush 13, feed change unit 14, polished rod 15, feed leading screw 16, main spindle box lifting reduction box 17, column 18, clasp nut 19, main shaft speed change handle 20, feed change lever 21, coupling sleeve 22, boring bar supporting base 23 crouches, table slide.

Fig. 1 is upright borer position, and clamping workpiece is on workbench, and collar bush 12 is perpendicular to workbench, and spindle end is by the dress boring cutter, and its boring cutter rotation is also done the feeding of vertical table direction.Boring (Fig. 2) is by motor A transmission, and through 4 pairs of gear graduations of gearbox, by big bevel pinion transmission polished rod 14, through feed change unit 13, a pair of pulley concial disk drives main shaft and rotates, and makes the boring cutter rotation.Worm screw is arranged at polished rod 14 bottoms, after worm and wormwheel slows down, rotate by a pair of 45 ° of helical gear turn-screws 15 through gear graduation (variable herein two kinds of rotating speeds), be equipped with clasp nut 18 in leading screw 15 and feed change unit 13 contact positions, pull clasp nut handle 18, when making it closed, boring cutter is made length feed.Boring cutter work driving-chain is the same with upright boring when crouching boring, different is that boring head and boring cutter rotation transmission system are all rotated 90 ° (shown in Figure 3), connect boring bar 5 at boring head, the boring bar other end is supported on the boring supporting base 22 that crouches, and boring bar passes workpiece hole and carries out boring.

Press the dress honing head at boring head during honing, the bistrique driving-chain that rotatablely moves is consistent (see figure 2) with boring, but former leading screw 15 length feed change-speed gearings are put neutral position, clasp nut 18 separately, on feed change unit 13, be equipped with lance, on main spindle box 7, be equipped with two travel switches 8, be equipped with on the lance and ram 11, after the travel position of raming, the impact stroke switch contact makes motor C do rotating, by series of gears (Fig. 2) collar bush 12 is moved up and down, it is reciprocating in by grinding out to drive honing head, finishes the honing operation.Change the position of collision block 11 on lance, the stroke of decision honing head, honing moves back and forth speed change, is controlled by jaw clutch.Upright boring can be carried out vertical boring cylinder, vertical honing, boring valve seating, vertical milling plane, and the different anchor clamps that change the outfit get final product boring automobile front axle main bearing hole, steering worm wheel case hole.

Upright boring can be turned to the borer position of crouching, locating piece A(Fig. 4 is arranged) before passing the cylindrical gear box casing 26 of coupling sleeve, on coupling sleeve 21 housings locating piece B is arranged, worm screw 24 is housed on this housing, at locating piece A rear portion, by the helical teeth circle is housed, it has toothed portion to account for whole circle 1/4 on the cylindrical gearbox 26, account for 90 ° of positions, gear ring and worm engagings by pivot.Be equipped with eccentric rod 27 at coupling sleeve 21 case top lid 25 high spots, its two ends place and the lower casing bearing block that links, and the clamping action of loam cake to cylindrical gear box casing can be cancelled or increase to rotating eccentricity bar 27 just.Fig. 4 is each parts operating position when standing the borer position, and in the time will changing the boring position, cancellation locating piece B goes up set screw earlier, rotate the eccentric rod handle, reduce the housing clamping force, rotate handwheel and make the worm screw rotation, the rotation of worm screw just drives gear box casing by worm-gear toothing and rotates.Main spindle box, collar bush etc. all are connected with housing, whole boring mechanism rotates simultaneously, when locating piece B contacts with the C piece, by setting a screw, and rotate eccentric rod, make cylindrical gear box casing clamped, upright boring changes to the borer position (Fig. 3) of crouching, and crouch borer position boring bar one end and boring head place connect, and an end passes the boring boring bar bearing seat 22 that crouches, workpiece places on the workbench, and boring engine spindle hole, camshaft hole and gear box casing, rear axle housing body dead eye are all used this method.If do not adorn boring bar, and adorn special-purpose boring head, but on workbench, increase anchor clamps boring engine link major part and microcephaly's bearing shell.
