Abstract
The utility model relates to an automatic feeding device of drilling machine belongs to machining equipment. The automatic switching and fast retreating of the drill bit can be completed through a screw rod mechanism, a differential gear and a friction controller, the relation of automation, high efficiency and portability is well processed, and the automatic switching and fast retreating device is particularly suitable for field operation
Description
The auto-feeder of the drilling machine that the utility model is related belongs to the portable mechanism process equipment.
Railway department is when carrying out the rail track management maintenance, and it is that rail web place is holed that a regular field work is arranged.At present, it is manual, a variety of automatically that domestic this kind equipment has, but to the feeding of drill bit good solution of neither one all, the machinery of some energy auto-feed, but fail to coordinate relation and the performance and the light relation of drilling, F.F. and rewind down, thereby restricted the automation development process of this kind equipment.
The purpose of this utility model is to provide a kind of auto-feeder of drilling machine, use can when holing, can adjust drilling automatically, sky advances and the empty feeding speed that moves back, thereby improve working (machining) efficiency.Further to be that the automatic drilling machine that is equipped with this device is compared other similar devices light for purpose, is applicable to field work, such as the drilling of the rail of railway department.
The technical scheme that adopts that achieves the above object is: the auto-feeder that a kind of drilling machine is used, comprise main shaft and main shaft drives mechanism, this device have one with coaxial leading screw that connects of main shaft rigidity and feed screw nut, a differential gearing, it is characterized in that having on the feed screw nut conical surface, this conical surface matches with the conical surface on the differential gearing; Be provided with a friction controller, this friction controller and feed screw nut are circumferentially fixing but can slide to axial, with frame (or be fixed on the frame part) annular contact surface are arranged and guarantee the pressure that contacts of appropriateness.
Accompanying drawing 1 is the organigram of embodiment (the auto-feed part of rail automatic drilling machine).
The embodiment that provides below in conjunction with accompanying drawing is described further.
See accompanying drawing 1, two linkage gears (1), (3) of rotating synchronously with motor shaft drive main motion gear (19) and differential gearing (17) simultaneously, the main motion gear rotates by flat key drive shaft cover (21), collar bush rotates by feather key drive shaft (22), with the also rotation synchronously of leading screw (13) of main shaft rigid attachment.Sky advances or sky when moving back, main shaft does not have axial load, feed screw nut (14) does not almost contact pressure with the cooperation conical surface between the differential gearing, friction controller (9) and the cooperation conical surface between the frame top board (6) have by what spring (11) provided and contact pressure (can adjust), can produce moment of friction, the rotation of restriction feed screw nut (with friction controller splined) realizes F.F. or rewind down; During cutting, because the effect of axial load, the contact pressure that the contact pressure that is subjected on the seam thick stick nut conical surface is subjected on the friction controller conical surface, make differential gearing drive nut and produce the rotation (number of teeth of the gear ratio main motion gear of differential gearing many) of rotating speed, realize the slow feeding of main shaft a little less than main shaft by moment of friction.In addition, sky advances to move back with sky has all established a stop bit, and at stop bit, main shaft contacts with the rear end face of nut with the front end face or the leading screw of nut, drives nut and rotates synchronously, main shaft is not advanced also do not move back.
Clamping device is arranged on the drilling machine in addition, when guaranteeing work and rail fix.
The major parameter of embodiment is as follows:
Drive motors:, power 1kw, rotating speed 300r/min
Main driven wheel is right: modulus 2.5mm, the number of teeth 25/43
Differential gearing is right: modulus 2.5mm, gear ratio 25/44, displacement
Leading screw: T26 * 6
Motion state when embodiment works:
The speed of mainshaft is 174r/min,
Sky advance or during empty moving back the rotating speed of feed screw nut be 0
Sky advances or sky when moving back main axle moving speed be revolution pitch, i.e. 6mm/r
The rotating speed of feed screw nut is 170r/min during drilling
The main shaft depth of cut is revolution 1/44 pitch, i.e. 0.136mm/r during drilling
The rail automatic drilling machine of making by such scheme and embodiment has following characteristics: 1, simple to operate, the efficient height behind the clamping, only need be opened, move back, stops three controls and can finish the work, and F.F., drilling link up automatically and carry out.2, the structure uniqueness is in light weight, and 30 kilograms of complete machine less thaies are convenient to carrying.
Each parts explanation in the accompanying drawing 1:
1, main motion gear driving wheel 2, casing 3, differential gearing driving wheel
4, motor shaft 5, bearing 6, pressing plate 7, pressure regulation double-screw bolt 8, nut
9, friction controller 10, pressure bearing 11, spring 12, stop bit retaining
13, leading screw 14, feed screw nut 15, regulator board 16, thrust bearing
17, differential gearing 18, bearing 19, main motion gear 20, bearing
21, collar bush 22, main shaft
