Abstract
The utility model discloses a drilling machine capable of accurately positioning workpieces. The drilling machine comprises a drilling machine body and a drilling machine worktable (4), wherein a steel bloom (3) is arranged at the center of the drilling machine worktable; a through hole which extends downwards, penetrates through the drilling machine worktable and allows a collet chuck (1) to extend into is formed in the center of the steel bloom; a lever mechanism is fixedly connected onto the drilling machine body below the through hole; a connecting rod (5) which extends upwards and is connected with the collet chuck is movably connected onto the lever mechanism; and when the connecting rod is driven by the lever mechanism to vertically move, the collet chuck can be controlled to zoom. The drilling machine disclosed by the utility model has the beneficial effects that the vertical movement of the connecting rod is controlled by matching a pedal on a transverse plate with a spring to pull the collet chuck to stretch or push the collet chuck to contract, and thus the work efficiency is increased and the dimensional accuracy of processing workpieces is higher.
Description
Technical field
The utility model relates to drilling machine, and relating in particular to can be to the pinpoint drilling machine of workpiece.
Background technology
When field of machining needs the end face of part to hole to the axle class, usually adopt drilling machine boring, general way is: scroll chuck is fixed on the work top of drilling machine, mix up the hand scroll chuck of opening of use one by one behind the center, the workpiece of packing into, the range estimation punching degree of depth, hole drilling is complete, again open scroll chuck, take out workpiece.Scroll chuck adopts the stator locking principle, and moment is larger, easily causes work top to rock during work, can't position for slightly long part simultaneously, the degree of depth of drawbore can only be measured with the dip stick that range estimation or drilling machine carry, and the drawback of this way is that work efficiency is slow, poor dimensional precision.
The utility model content
When the technical problems to be solved in the utility model is existing drilling machine boring, effect is slow, and poor dimensional precision provides a kind of drilling efficiency high for this reason, and what dimensional accuracy was good can be to the pinpoint drilling machine of workpiece.
The technical solution of the utility model is: can be to the pinpoint drilling machine of workpiece, it comprises drilling machine body and Drilling machines bench, central authorities are provided with bloom at Drilling machines bench, bloom central authorities are provided with to downward-extension and run through the through hole that stretches into for collet chuck of Drilling machines bench, be connected with leverage on the drilling machine body of described through hole below, be connected with the connecting rod that extends upward and be connected with collet chuck on described leverage, described connecting rod is driven by leverage can control the convergent-divergent of collet chuck when moving up and down.
Leverage described in such scheme comprises the first column and the transverse slat that is movably connected on the first column, is connected with connecting rod on described transverse slat, and the end of transverse slat is provided with pedal, and when pushing down on the pedal, the transverse slat drivening rod moves downward, thereby pulls collet chuck to tighten.
One side of transverse slat described in such scheme is provided with the second column, is connected pedal one side and connects by spring in the top of the second column with transverse slat, and when unclamping pedal, but thereby on the spring drivening rod, the top is opened collet chuck.
The beneficial effects of the utility model are to be used in conjunction with moving up and down of control link by the pedal on transverse slat and spring pull collet chuck to open or promote the collet chuck contraction, have improved operating efficiency, and the dimensional accuracy of processing work is higher.
Description of drawings
Fig. 1 is the utility model schematic diagram;
In figure, 1, collet chuck, 2, workpiece, 3, bloom, 4, Drilling machines bench, 5, connecting rod, 6, spring, 7, pedal, the 8, first column, 9, transverse slat, the 10, second column.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in the figure, the utility model comprises drilling machine body and Drilling machines bench 4, central authorities are provided with bloom 3 at Drilling machines bench, bloom central authorities are provided with to downward-extension and run through the through hole that stretches into for collet chuck 1 of Drilling machines bench, be connected with leverage on the drilling machine body of described through hole below, be connected with the connecting rod 5 that extends upward and be connected with collet chuck on described leverage, described connecting rod is driven by leverage can control the convergent-divergent of collet chuck when moving up and down.
Concrete, described leverage comprises the first column 8 and the transverse slat 9 that is movably connected on the first column, is connected with connecting rod on described transverse slat, and the end of transverse slat is provided with pedal 7, and when pushing down on the pedal, the transverse slat drivening rod moves downward, thereby pulls collet chuck to tighten.
Further, can reset after pedal is stepped in order to make transverse slat, be connected pedal one side and connect by spring 6 in the top that transverse slat one side is provided with the second column 10, the second columns with transverse slat, and when unclamping pedal, but thereby on the spring drivening rod, the top is opened collet chuck.
The utility model is such use: after inserting workpiece 2 in collet chuck, pedal 7 shrinks collet chuck, with Workpiece clamping, after work termination boring, loosens pedal, and spring 6 pulls transverse slat to make on connecting rod and pushes up, and collet chuck is pushed up pine, and workpiece is jumped out from fortune.
In the utility model, collet chuck internal diameter and workpiece external diameter are suitable, and length of connecting rod and the workpiece degree of depth are suitable.
