Abstract

The invention discloses an automatic center drilling device which comprises a base (6), a sliding rod seat (4) and a hand wheel (3). A double-headed screw (5) is fixedly connected onto the hand wheel (3), the base (6) is provided with a clamping plate (8) and a groove close to the sliding rod seat (4), the groove is matched with the sliding rod seat (4), the sliding rod seat (4) is fixedly connected with a sliding rod (7) close to the base, through holes matched with the sliding rod (7) and the double-headed screw (5) are formed in the base (6), two sides of the base (6) are movably connected with rotating curved rods (1), a center clamping block (2) is movably connected onto each rotating curved rod (1), one end of the clamping plate (8) far away from the base (6) is fixedly connected with a drill bushing (9), and the extended line of the axis of the drill bushing (9) is intersected with and perpendicular to that of the axis of the double-headed screw (5). When the automatic center drilling device is used, the two center clamping blocks move towards opposite inner sides, and a workpiece is clamped.

Description

Drilling equipment in a kind of automatic minute
Technical field
The present invention relates to drilling equipment in a kind of automatic minute.
Background technology
In prior art, need to be when workpiece central bore, conventionally just with artificial line, find out and put into drilling machine behind center, hole and punch, adopt the mode of artificial line expend time in and have error.
Summary of the invention
The mode that the object of the invention is the artificial line of solution expends time in and has error problem.
The technical solution used in the present invention is: drilling equipment in a kind of automatic minute, it comprises pedestal, slider block, handwheel, on described handwheel, be connected with double threaded screw, described slider block is movably connected in double threaded screw near one end of handwheel, described pedestal near slider block place be provided with pressure strip and with the suitable groove of slider block, described pressure strip and pedestal are connected, on described slider block, near pedestal place, be fixed with slide bar, on pedestal, have and slide bar and the suitable through hole of double threaded screw, one end of described double threaded screw is stretched out slider block end face and is stretched into pedestal double threaded screw is threaded with pedestal, and the end face of pedestal is stretched out in the end that double threaded screw stretches into one end of pedestal, described pedestal both sides are all connected with rotating curved bar, on each rotating curved bar, be connected with a minute middle clamp, in 2 minutes, clamp line centered by the axis of double threaded screw is symmetric, one end of described slide bar stretch out through hole and with minute in the end face of clamp be affixed, described pressure strip is fixed with drill bushing away from one end of pedestal, the extended line of the axis of described drill bushing intersects with the extended line of the axis of double threaded screw and is vertical.
As a further improvement on the present invention, one end that described pedestal is connected with rotating curved bar is extended and is made pedestal be butterfly to the one end away from handwheel.
The invention has the beneficial effects as follows: rotate handwheel, slider block is near pedestal direction, motion makes the slide bar of pedestal promote a minute middle clamp, a clamp in being connected with because described rotating curved bar is flexibly connected with pedestal, on each rotating curved bar minute, so thereby clamp is realized the clamping to workpiece to phase direction motion to the inside in two minutes, after Workpiece clamping, by drill bushing, workpiece is punched, improved operating efficiency and reduced error.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 is the side view of Fig. 2.
Shown in figure: 1 rotating curved bar, clamp in 2 minutes, 3 handwheels, 4 slider blocks, 5 double threaded screws, 6 pedestals, 7 slide bars, 8 pressure strips, 9 drill bushings, 10 workpiece.
The specific embodiment
Below in conjunction with Fig. 1,2,3, the present invention is described further.
As Fig. 1, 2, shown in 3, drilling equipment in a kind of automatic minute, it comprises pedestal 6, slider block 4, handwheel 3, on described handwheel 3, be connected with double threaded screw 5, described slider block 4 is movably connected in double threaded screw near one end of handwheel 3, described pedestal 6 near slider block 4 places be provided with pressure strip 8 and with the suitable groove of slider block 4, described pressure strip 8 is connected with pedestal 6, on described slider block 4, near pedestal place, be fixed with slide bar 7, on pedestal 6, have and slide bar 7 and the suitable through hole of double threaded screw 5, one end of described double threaded screw 5 is stretched out slider block 4 end faces and is stretched into pedestal 6 double threaded screw is threaded with pedestal, and the end face of pedestal 6 is stretched out in the end that double threaded screw 5 stretches into one end of pedestal 6, described pedestal 6 both sides are all connected with rotating curved bar 1, on each rotating curved bar 1, be connected with a minute middle clamp 2, in 2 minutes, clamp 2 line centered by the axis of double threaded screw 5 is symmetric, one end of described slide bar 7 stretch out through hole and with minute in the end face of clamp 2 be affixed, described pressure strip 8 is fixed with drill bushing 9 away from one end of pedestal 6, the extended line of the axis of described drill bushing 9 intersects with the extended line of the axis of double threaded screw 5 and is vertical, described pedestal 6 is connected with one end of rotating curved bar 1 and extends and make pedestal 6 be butterfly to the one end away from handwheel 3.
When the present invention uses, rotate handwheel 3, slider block 4 is near pedestal, 6 direction motions make the slide bar 7 of pedestal 6 promote a minute middle clamp 2, a clamp 2 in being connected with because described rotating curved bar 1 is flexibly connected with pedestal 6, on each rotating curved bar 1 minute, so thereby clamp 2 is realized the clamping to workpiece 10 to phase direction motion to the inside in two minutes, after workpiece 10 clamps, by 9 pairs of workpiece of drill bushing, punch, improved operating efficiency and reduced error.
Those skilled in the art should know; protection scheme of the present invention is not limited only to the above embodiments; can also on the basis of above-described embodiment, carry out various permutation and combination and conversion; under the prerequisite without prejudice to spirit of the present invention, the various conversion that the present invention is carried out all drop in protection scope of the present invention.
