Description

Rotary manual feed mechanism
Technical field
The present invention relates to bar production field, especially a kind of rotary manual feed mechanism.
Background technology
In stainless Bar Plant, existing bar is holed or in chasing bar, the artificial electric drill of taking of a kind of employing of existing small enterprise is holed to bar, and the hole that this mode comes outbreak out is easy inclination generally, the bad control of the degree of depth, and higher to the technical requirement of workman; Another kind is that bar is in boring or chasing bar, bar is clamped motionless, drive the axially-movable together with cutter of whole motor by feed arrangement, in order to the precision of axially-movable, generally such device all can adopt lead screw transmission, but airborne dust is many in factory, the easy corrosion and ageing of leading screw, and the general all complex structures of such device, complex operation, expensive, cost is higher.
Summary of the invention
The technical problem to be solved in the present invention is: hole to bar to solve existing artificial electric drill of taking, the hole that this mode comes outbreak out is easy inclination generally, the bad control of the degree of depth, and higher and existing bar boring or tapping machine all can drive the axially-movable together with cutter of whole motor by feed arrangement to the technical requirement of workman, adopt lead screw transmission, but airborne dust is many in factory, the easy corrosion and ageing of leading screw, and the general all complex structures of such device, complex operation, expensive, the problem that cost is higher, now provides a kind of rotary manual feed arrangement.
The technical solution adopted for the present invention to solve the technical problems is: rotary manual feed mechanism, comprise axle sleeve, splined shaft, bearing block, axle and casing, described axle sleeve connecting power device, splined shaft has spline one end and axle sleeve to be slidably connected, bearing block is slidably mounted on bottom half, bearing is provided with in bearing block, bearing outer ring and bearing block interference fit, splined shaft is arranged in bearing without spline one end, and with bearing inner race interference fit, bearing block side is provided with tooth bar near bottom, at right angle setting axle on casing is also positioned at tooth bar and has tooth side, axle is provided with and tooth bar meshed gears.In order to splined shaft can be made with bearing block one piece of movement, bearing outer ring and bearing block interference fit, splined shaft is arranged in bearing without spline one end, and with bearing inner race interference fit, the moving belt dynamic bearing of bearing block, bearing inner race and splined shaft interference fit drive splined shaft to move.
In order to bearing block can be made to move at bottom half, described bearing block bottom surface is provided with two parallel guide rails, and bottom half has two grooves matched with described bearing block floor rails.
In axial direction move for convenience of Non-follow control splined shaft, described axle is provided with rocking handle and is positioned at casing outside, makes splined shaft axially-movable by rotation crank.
Preferably, guide rail is T-shaped guide rail, and described groove is T-slot.
Preferably, bearing is taper roll bearing.
The invention has the beneficial effects as follows: it is simple that rotary manual feed mechanism of the present invention has structure relative to prior art, and cost is low, greatly boosts productivity, and the degree of depth of boring or tapping easily controls, and requires lower to operating personnel.
