Description
Technical field
The present invention relates to a kind of drilling equipment, more particularly to a kind of center positioning device of shaft member.
Background technology
Ball connection is to be required for connecting ball head in the connected mode commonly used during shaft member is connected, therefore many shaft member, for example, become
Fast bar is exactly the ball connection used；Because the rate of wear of bulb is very fast, so the bulb and control stick of usual gear lever are not
It is integrally formed, but control stick is to be threadedly coupled with bulb, consequently facilitating the replacing of bulb；Therefore bulb generally include spheroid and
One shorter connecting rod, and screwed hole is generally shot with the end face of connecting rod, and positioned at connecting rod center.Due to the limit of the profile of bulb
System, therefore be very unlikely to be clamped, clamping mode now is typically that bulb is clamped using upper and lower mould, upper die and lower die
On be provided with hemisphere face, and a through hole is additionally provided with upper mould, so that connecting rod is inserted, while through hole and connecting rod coordinate pair
Bulb carries out spacing.Due to being clamped using mould to bulb so that a fixture, the ball of same size only can be suitably used for
Head, can have error additionally, due to each bulb, so that it sometimes appear that clamp more loose situation, thus can make vibration compared with
Greatly, so that mismachining tolerance is also increased.
The content of the invention
The invention is intended to provide a kind of center positioning device of shaft member, so that this fixture adapts to multiple serial bulbs.
The center positioning device of the base case shaft member of the present invention, including frame, drill bit and clamp system, the drill bit and
Clamp system is installed in frame, and drill bit, by automatic control system control, the automatic control system includes PLC
With and gear drive；The clamp system includes pedestal, positioning gland and locating rod；The pedestal includes mounting seat and solid
It is scheduled on the sleeve pipe of mounting seat upper end；The positioning gland is threaded in the upper end of sleeve pipe, and positioning gland is provided centrally with
Taper hole directed downwardly is held greatly, and positioning gland upper end is additionally provided with two along the centrosymmetric blind hole of positioning gland；The locating rod is set
In the upper end of mounting seat, and the conical socket held greatly upward is provided with the upper end of locating rod.
In this base case, workpiece is located in sleeve pipe, and between positioning gland and locating rod；By rotating upper end
Positioning gland, taper hole is provided centrally with due to positioning gland, so during positioning gland is gradually pushed, workpiece upper end
Connecting shaft can gradually with taper hole center superposition so that by the connection shaft assignment of workpiece, and clamp；Then just workpiece can be entered
Row drilling.
In this programme, center positioning hole except have to workpiece clamp and positioning action in addition to, also with making what drill bit passed through
Effect, so that drill bit energy workpiece is drilled.And the conical socket of the upper end of locating rod can make locating rod and workpiece formation line
Contact, makes clamping more stablize, and workpiece is placed on conical socket and will not rotated, so as to have the work of Primary Location to workpiece
With；Therefore the taper hole on conical socket and positioning gland coordinates, and is more beneficial for the positioning to workpiece.It is fixed that other bearing pin can be plugged into
In blind hole on the gland of position, using lever principle rotational positioning gland, so as to reach labour-saving effect, it is fixed sufficiently to make again
Position gland workpiece pressing.
This programme carries out spacing clamping to bulb using the conical surface, because the conical surface can agree with various sizes of bulb, so that
The bulb of sizes can be clamped, also therefore, it is possible to overcome the error of each bulb, preferable fastening effect is reached.
Preferred scheme one, as the further optimization to base case, the locating rod is threaded in the mounting seat
Upper end, and the lower end of locating rod is provided with a pin-and-hole；Locating rod is threadedly coupled with mounting seat, can be adjusted by rotational positioning bar
The height of the whole location of workpiece, so that the upper end surface of the workpiece of different size is being changed to different shaped in sustained height with this
Number workpiece when, drill bit can be positioned without again.
Preferred scheme two, as the further optimization to base case, described sleeve pipe is circumferentially also symmetrically divided along cannula center
It is furnished with four Top fastening screws；Due to positioning gland and locating rod with workpiece be linear contact lay, so Top fastening screw can be further right
Workpiece is clamped, to reduce the vibration of workpiece.
Preferred scheme three, as the further optimization to base case, the upper end of the mounting seat is provided with some through holes, and
Through hole is in sleeve pipe；When being processed to workpiece, there are iron filings to enter in sleeve pipe unavoidably, then it is some logical in mounting seat
Hole is conducive to clearing up iron filings.
Brief description of the drawings
Fig. 1 for shaft member center positioning device embodiment in clamp system structural representation.
Embodiment
Below by embodiment, the present invention is further detailed explanation：
Reference in Figure of description includes：Mounting seat 1, sleeve pipe 2, positioning gland 3, Top fastening screw 4, locating rod 5,
Workpiece 8, taper hole 21, conical socket 51.
Embodiment is substantially as shown in Figure 1：The center positioning device of shaft member includes frame, drill bit and clamp system, wherein
Drill bit and clamp system are installed in frame, and drill bit, by automatic control system control, automatic control system is controlled including PLC
Device and and gear drive.Clamp system includes pedestal, positioning gland 3, locating rod 5 and Top fastening screw 4.Wherein pedestal includes
Mounting seat 1 and the sleeve pipe 2 for being welded on the upper end of mounting seat 1；Positioning gland 3 is threaded in the upper end of sleeve pipe 2, and positioning gland 3
Be provided centrally with taper hole 21, and taper hole 21 big end down, be additionally provided with positioning gland 3 along the Central Symmetry of positioning gland 3
