Abstract
The utility model discloses a feed depth adjustment device of a hydraulic control drill, which comprises a drill shell, and a feed depth adjustment device arranged on the side wall of the shell, wherein a spindle is rotatably arranged in the drill shell, and one end of the spindle extends out of the top end of the drill shell; two limit nuts are arranged on the extending end of the spindle, and a spindle dustproof cover is covered outside the spindle; the feed depth adjustment device comprises an upper travel switch and a lower travel switch which are arranged on the side wall of the drill, and a gauge screw rod is arranged beside the upper and lower travel switches; and an upper limit travel nut and a lower limit travel nut are arranged on the gauge screw rod. The automatic feed device of the drill has the advantages of simple structure, less mechanical wear and longer service life.
Description
Technical field
The utility model relates to a kind of depth of cut adjusting device of hydraulic control drill bit.
Background technology
Drilling machine bores cutter and leans on the rotation of main shaft to realize cutting when work, accomplishes feed and withdrawing through moving down of main shaft again; The rotation of main shaft drives and realizes through be connected transmission device with drive of motor; And moving up and down through machine driving of main shaft realizes, existing drilling machine feed arrangement, and its structure is included in the belt gear of adorning on the head; The belt reduction gearing mechanism, one-level turbine bar reducing gear.Traditional feed velocity can only change with the transmission mechanism middle belt pulley diameter of transposing belt; This transposing is not only comparatively bothersome, time-consuming; But also can only realize that because of belt pulley can only the section of having must change the main shaft feed section of having regulates, can not satisfy the selection of people to the feed optimum speed.
The utility model content
It mainly is the shortcoming that exists in the above-mentioned prior art of customer service that the utility model provides, and a kind of depth of cut adjusting device of hydraulic control drill bit is provided, simple and reasonable, borehole accuracy is high.
The utility model technical solution problem provides following scheme:
A kind of depth of cut adjusting device of hydraulic control drill bit; Comprise the drill bit housing, be installed in the depth of cut adjusting device on the housing sidewall; Be rotatablely equipped with main shaft in the said drill bit housing, an end of said main shaft stretches out from the top of drill bit housing, and two stop nuts are installed on the said main shaft external part; The outside of main shaft is covered with the main shaft dust cover; Said depth of cut adjusting device includes upper stroke switch and the lower stroke switch that is installed on the drill bit sidewall, and the said next door of travel switch up and down is provided with the scale screw mandrel, and said screw mandrel is provided with upper limit stroke nut and lower bound range nut.
The utility model is loaded onto suitable cutter as required, opens the main shaft dust cover, unclamps two hexagonal stop nuts on the main shaft, makes it to enough processing travel position, adjusts two up stroke adjusting nuts, makes upper stroke switch work.Unclamp two down stroke adjusting nuts, power switch is allocated to " opening ", power supply indicator is bright; The mode of operation handle is allocated to " manually ", and operation " manually feed " knob makes the position that main shaft is displaced downwardly to be needed.Adjustment down stroke adjusting nut makes lower stroke switch work (the stroke adjustment also can transfer to the scale position unit and the locking that need with the down stroke nut and get final product with reference to the graduated scale of scale bar).At last with two hex nuts be adjusted to above the spline housing by flat and locking, play position-limiting action, the main shaft dust cover of screwing gets final product.
The utility model can be realized the no section adjusting of feed velocity; Thereby can accomplish into drilling with the feed velocity of the best; And progress is good, and the utility model can also idle running returning quickly mechanism make the idle running of boring cutter return rapidly, the utility model drilling machine automatic feeder simple in structure; Mechanical wear is less, and service life is longer.
Description of drawings
Fig. 1 is the partial structurtes sketch map of the utility model.
Fig. 2 is the utility model depth of cut adjusting device structural representation.
The specific embodiment
Referring to accompanying drawing; A kind of depth of cut adjusting device of hydraulic control drill bit comprises drill bit housing 1, is installed in the depth of cut adjusting device on housing 1 sidewall, is rotatablely equipped with main shaft 2 in the said drill bit housing 1; One end of said main shaft 2 stretches out from the top of drill bit housing 1; Two stop nuts 3 are installed on said main shaft 2 external parts, and the outside of main shaft 2 is covered with main shaft dust cover 4, and said depth of cut adjusting device includes the upper stroke switch 5 and lower stroke switch 6 that is installed on the drill bit sidewall; The said next door of travel switch 5,6 up and down is provided with scale screw mandrel 7, and said screw mandrel 7 is provided with upper limit stroke nut 8 and lower bound range nut 9.
