Abstract
The invention aims to provide a multi-head drill with adjustable hole pitch, which is structurally characterized in that an input shaft is connected with an input supporting bearing, a main transmission bearing I, a driving gear, an input shaft key, a spacer bush and a snap spring, and is fixed on a box body through a box cover; an output shaft is fixed on a rocker arm through a rocker arm bearing II, a baffle ring, a spacer bush, a rocker arm spacer bush, a driven gear, a rocker arm bearing I and an output shaft snap spring to form a rocker arm assembly; an intermediate drive gear is supported on a middle supporting shaft through an intermediate drive gear spacer bush, a rolling needle, a middle supporting shaft spacer bush I and a middle supporting shaft spacer bush II; the rocker arm assembly is fastened on a main shaft box through the middle supporting shaft and screw nuts; and a main transmission gear and the intermediate drive gear are mutually engaged and the intermediate drive gear and the driven gear are mutually engaged.
Description
Technical field
The present invention relates to a kind of adjustable pitch multi-head drill, belong to mechanical field.
Background technology
At present, in China multiple-drilling machine field, main traditional type is fixing hole apart from drilling, and being mainly used in oversized hole processes apart from drilling, but along with developing rapidly of mechanical industry, the simple function that original bull is bored can not satisfy user's diversification, the actual needs of flexible processing far away, it is necessary inventing a kind of adjustable pitch multi-head drill, for this reason, we have invented a kind of bull boring device of adjustable pitch, have solved bull and have bored special plane manufacturing cost height, produce flexible insurmountable problem.
Summary of the invention
The object of the invention is to provide a kind of adjustable pitch multi-head drill equipment, it mainly is made up of power shaft (1), casing (5), case lid (26), driving gear (2), intermediate drive gear (4), intermediate supports axle (20), driven gear (9), output shaft (13), rocking arm (21), is uniform-distribution with several intermediate supports axle (20) holes on casing (5) and the case lid (26).Its architectural feature is as follows: power shaft (1) links together and is fixed on the casing (5) by case lid (26) with input spring bearing (19), main transmission bearing I (24), driving gear (2), input axle key (15), spacer (17), jump ring (10); Output shaft (13) is fixed on rocking arm (21) by rocker bearing II (25), baffle ring (12), spacer (11), rocking arm spacer (27), driven gear (9), rocker bearing I (8), output shaft jump ring (7) and goes up the composition Rocker arm assembly; Intermediate drive gear (4) is supported on the intermediate supports axle (20) by intermediate drive gear spacer (6), needle roller (23), intermediate supports axle spacer I (22) and intermediate supports axle spacer II (28); Rocker arm assembly is fastened on the casing (5) by intermediate supports axle (20), nut (16); Main drive gear (2) is meshed with intermediate drive gear (4), and intermediate drive gear (4) is meshed with driven gear (9).
Because the present invention has adopted said structure, simplified the bull boring device, can carry out rapid processing, realized one-machine-multi-function the product of various pitch-rows, while so architecture quality are not gently used the restriction of equipment, can use on power-equipments such as drilling machine, special plane and realize boring, tapping function.
Description of drawings
Accompanying drawing is inventive principle figure.
The specific embodiment
Be further described below in conjunction with the specific embodiment of accompanying drawing adjustable pitch multi-head drill device of the present invention: when the actuating unit output shaft that rotates with after bull brill power shaft (1) is connected, power is delivered on the driving gear (2) by the input axle key (15) that is fixed on the power shaft (1), be delivered on the intermediate drive gear (4) by the engagement of driving gear (2) with intermediate drive gear (4), be delivered on the driven gear (9) by the engagement of intermediate drive gear (4) again, pass to output shaft (13) by the output axle key (14) that cooperates with driven gear (9) then and drive drill bit realization boring or the tapping function that is fixed on the output shaft (13) with driven gear (9); When the needs adjustment hole apart from the time, unclamp nut (16) Rocker arm assembly rotated around intermediate supports axle (20), adjust to suitable pitch-row and position after, again Rocker arm assembly is fastened on the casing (5) by nut (16); For the quantity difference of machining hole, can realize by the quantity that adjustment is fixed on casing (5) upper rocker arm assembly.
Claims (2)
1, a kind of adjustable pitch multi-head drill, it mainly is made up of power shaft (1), casing (5), case lid (26), driving gear (2), intermediate drive gear (4), intermediate supports axle (20), driven gear (9), output shaft (13), rocking arm (21), is uniform-distribution with several intermediate supports axle (20) holes on casing (5) and the case lid (26).Its architectural feature is as follows: power shaft (1) links together and is fixed on the casing (5) by case lid (26) with input spring bearing (19), main transmission bearing I (24), driving gear (2), input axle key (15), spacer (17), jump ring (10); Output shaft (13) is fixed on rocking arm (21) by rocker bearing II (25), baffle ring (12), spacer (11), rocking arm spacer (27), driven gear (9), rocker bearing I (8), output shaft jump ring (7) and goes up the composition Rocker arm assembly; Intermediate drive gear (4) is supported on the intermediate supports axle (20) by intermediate drive gear spacer (6) needle roller (23), intermediate supports axle spacer I (22) and intermediate supports axle spacer II (28); Rocker arm assembly is fastened on the casing (5) by intermediate supports axle (20), nut (16); Main drive gear (2) is meshed with intermediate drive gear (4), and intermediate drive gear (4) is meshed with driven gear (9).
2,, can realize by the quantity that adjustment is fixed on casing (5) upper rocker arm assembly for the quantity difference of machining hole.
