Abstract
The invention relates to a movable and convenient center hole drilling machine which is characterized in that a guide post is fixedly mounted on the back surface of a three-jaw center chuck; a movable sliding plate is mounted on the guide post; a reduction box, a motor and other working mechanisms are fixedly mounted on the sliding plate; and the forward and backward movements of the sliding plate is driven by a hydraulic cylinder composed of an annular piston cylinder and an annular piston which are mounted at the end part of the guide post. The movable and convenient center hole drilling machine has the advantages of simple structure and flexible and convenient operation process, is suitable for the maintenance of small-lot individual shaft parts, and satisfies the requirements for machining center holes on large or overlong shaft workpieces.
Description
Technical field
The present invention relates to a kind of centre-drilling hole machine, particularly a kind of mobile, nimble formula centre bore rig belongs to hardware & tools or metal cutting machinery equipment technical field.
Background technology
In the processing of axial workpiece, generally to get out the centre bore that technology is used in advance at the two ends of axle, and with this hole as benchmark, process other position.At present, in enormous quantities and the less shaft-like workpiece of length, the centre bore at its two ends generally is to get out with centre-hole machine; But; For the maintenance of small lot, single-piece axial workpiece, for less investment of devices, the general employing by hand rule; Adopt other rig again, get out centre bore at two ends; For the shaft-like workpiece of large-scale or overlength, owing to there is not large-scale centre-drilling lathe, also be to adopt manual line, adopt other rig again, get out the method for centre bore at two ends.Because the method for manual line drill centers, rule personnel experience limits, and has bigger error, so not only labour intensity is bigger, simultaneously, also has unstable product quality, second-rate defective.
Summary of the invention
The objective of the invention is to: a kind of mobile, nimble formula centre bore rig is provided, adapts to the maintenance of small lot, single-piece axial workpiece; And the needs in the shaft-like workpiece machining center hole of large-scale or overlength, overcome the maintenance of existing small lot, single-piece axial workpiece; And in the process in the shaft-like workpiece machining center hole of large-scale or overlength, owing to adopt the method for manual line boring, existing: labour intensity is big, unstable product quality, second-rate defective.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind ofly move, nimble formula centre bore rig, it is grabbed center chuck, drill chuck, back-moving spring, guide pillar, set bolt, slide plate, annular piston, annular piston cylinder, hold-down nut, reduction box, motor by three and forms; Described guide pillar is by identical forming more than two or two, and guide pillar is through the one of which end, be fixed on evenly three grab the center chuck the back side; Slide plate is installed together through the relation that the hole cooperates with guide pillar; And slide plate is with respect to the free degree that causes having slip, and described spring is installed in slide plate and three in advance and grabs above the guide pillar between the chuck of center, and described reduction box is fixed on the centre in slide plate left side with set bolt; The centre of slide plate has manhole; The middle manhole and three of slide plate is grabbed center chuck intermediate throughholes and is in above same the axis, and the output shaft of described drill chuck and reduction box is installed together, and described motor is fixed on an end of reduction box; Described annular piston is installed together through the relation that the hole cooperates with guide pillar; And annular piston has the free degree of slip with respect to guide pillar, and described annular piston cylinder is fixed on the end of guide pillar with hold-down nut, and the plunger shaft of annular piston cylinder and annular piston form matching relationship.
Operation principle of the present invention is: when the needs drill centers, grab center chuck catching directly with the end of these facility clip at axle through three, when in the annular piston cylinder during logical people's pressure oil; Just driving annular piston moves; Move together thereby drive slide plate, owing to reduction box, motor and slide plate are fixed together, so; Just drive drill chuck and move, realize work feed to workpiece.
Beneficial effect: the present invention compares with existing centre-drilling lathe, has advantage simple in structure, flexible and convenient to use, simultaneously, can adapt to the maintenance of small lot, single-piece axial workpiece; And the needs in the shaft-like workpiece machining center hole of large-scale or overlength, overcome the maintenance of existing small lot, single-piece axial workpiece; And in the process in the shaft-like workpiece machining center hole of large-scale or overlength, owing to adopt the method for manual line boring, existing: labour intensity is big, unstable product quality, second-rate defective.
