Description
Technical field
The present invention relates to a kind of drilling equipment, particularly relate to a kind of center positioning device of shaft member.
Background technology
It is connected mode conventional during shaft member connects that ball connects, and therefore a lot of shaft member all needs connecting ball head, and such as gear lever is exactly that the ball adopted connects; Because the rate of wear of bulb is very fast, thus usually the bulb of gear lever and control stick not one-body molded, but control stick and bulb are for being threaded, thus are convenient to the replacing of bulb; Therefore bulb generally includes spheroid and a shorter connecting rod, and screwed hole is shot with the end face of connecting rod usually, and is positioned at connecting rod center.Due to the restriction of the profile of bulb, therefore pole is not easy to be clamped, clamping mode now normally adopts upper and lower mould to clamp bulb, upper die and lower die are provided with hemisphere face, and on patrix, be also provided with a through hole, to make connecting rod insert, simultaneously through hole coordinates with connecting rod and carries out spacing to bulb.Owing to adopting mould to clamp bulb, make a fixture, only can be applicable to the bulb of same size, in addition because each bulb can exist error, thus there is the situation that clamping is more loose sometimes, vibration therefore can be made comparatively large, thus mismachining tolerance also strengthen.
Summary of the invention
The invention is intended to the center positioning device that a kind of shaft member is provided, with the bulb making this fixture can adapt to multiple series.
The center positioning device of base case shaft member of the present invention, comprise frame, drill bit and clamp system, described drill bit and clamp system are installed in frame, and drill bit is by automatic controlling system, described automatic control system comprise PLC and and gear drive; Described clamp system comprises pedestal, positioning gland and backstay; Described pedestal comprises mount pad and is fixed on the sleeve pipe of mount pad upper end; Described positioning gland is threaded in the upper end of sleeve pipe, and the center of positioning gland is provided with large end taper hole down, and positioning gland upper end is also provided with two along the centrosymmetric blind hole of positioning gland; Described backstay is arranged on the upper end of mount pad, and is provided with large end conical socket upward in the upper end of backstay.
In this base case, workpiece is positioned at sleeve pipe, and between positioning gland and backstay; By rotating the positioning gland of upper end, because the center of positioning gland is provided with taper hole, so in the process pressed down gradually at positioning gland, the connecting axle of workpiece upper end can gradually with the center superposition of taper hole, thus by the connecting axle centering of workpiece, and clamp; Then just can hole to workpiece.
In this programme, center positioning hole, except workpiece being had to clamping and positioning action, also has the effect that drill bit is passed through, thus drill bit energy workpiece is holed.And the conical socket of the upper end of backstay can make backstay and workpiece form linear contact lay, make clamping more stable, and workpiece is placed on conical socket and can not rotates, thus to workpiece, there is the effect of Primary Location; Therefore the taper hole on conical socket and positioning gland coordinates, and is more conducive to the location to workpiece.Bearing pin can be inserted in the blind hole on positioning gland in addition, can utilize lever principle rotational positioning gland, thus reach labour-saving effect, can make positioning gland workpiece pressing fully again.
This programme adopts the conical surface to carry out spacing clamping to bulb, because the conical surface can agree with the bulb of different size, thus can clamp the bulb of sizes, also therefore, it is possible to overcome the error of each bulb, reach good fastening effect.
Preferred version one, as the further optimization to base case, described backstay is threaded in the upper end of described mount pad, and the lower end of backstay is provided with a pin-and-hole; Backstay is threaded with mount pad, by the height of the rotational positioning bar adjustment location of workpiece, thus making the upper end surface of the workpiece of different size in sustained height, with this when changing to the workpiece of different model, can position drill bit again.
Preferred version two, as the further optimization to base case, described sleeve circumferential is also symmetrically distributed with four along cannula center and holds out against screw; Be all linear contact lay with workpiece due to positioning gland and backstay, can clamp workpiece further so hold out against screw, to reduce the vibration of workpiece.
Preferred version three, as the further optimization to base case, the upper end of described mount pad has some through holes, and through hole is in sleeve pipe; Adding man-hour to workpiece, having iron filings can enter in sleeve pipe unavoidably, then the some through holes on mount pad are conducive to clearing up iron filings.
Accompanying drawing explanation
Fig. 1 is the structural representation of clamp system in the center positioning device embodiment of shaft member.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: mount pad 1, sleeve pipe 2, positioning gland 3, hold out against screw 4, backstay 5, workpiece 8, taper hole 21, conical socket 51.
Embodiment is substantially as shown in Figure 1: the center positioning device of shaft member comprises frame, drill bit and clamp system, wherein drill bit and clamp system are installed in frame, and drill bit is by automatic controlling system, automatic control system comprises PLC and and gear drive.Clamp system comprises pedestal, positioning gland 3, backstay 5 and holds out against screw 4.Wherein pedestal comprises mount pad 1 and is welded on the sleeve pipe 2 of mount pad 1 upper end; Positioning gland 3 is threaded in the upper end of sleeve pipe 2, and the center of positioning gland 3 is provided with taper hole 21, and the large end of taper hole 21 down, positioning gland 3 is also provided with along the centrosymmetric blind hole of positioning gland 3, so that rotational positioning gland 3.Backstay 5 is threaded in the upper end of mount pad 1, and the upper end of backstay 5 is provided with conical socket 51, and is provided with a pin-and-hole in the lower end of backstay 5, to facilitate rotational positioning bar 5.Also be distributed with four along sleeve pipe 2 Central Symmetry in sleeve pipe 2 circumference and hold out against screw 4.
As shown in Figure 1, workpiece 8 is positioned at sleeve pipe 2, and between positioning gland 3 and backstay 5; By rotating the positioning gland 3 of upper end, center due to positioning gland 3 is provided with taper hole 21, so in the process pressed down gradually at positioning gland 3, the connecting axle of workpiece 8 upper end can gradually with the center superposition of taper hole 21, thus by the connecting axle centering of workpiece 8, and clamp; Then just can hole to workpiece 8.
In the present embodiment, the conical socket 51 that the upper end of backstay 5 is arranged can make backstay 5 and workpiece 8 form linear contact lay, make clamping more stable, and workpiece 8 is placed on conical socket 51 and can not rotates, thus workpiece 8 is had to the effect of Primary Location, taper hole 21 on conical socket 51 and positioning gland 3 coordinates, and is more conducive to the location to workpiece 8.Adjusting the height of workpiece 8 position in addition by rotational positioning bar 5, thus make the upper end surface of the workpiece 8 of different size in sustained height, with this when changing workpiece 8, height and the change drill bit amount of feeding of adjustment drill bit can be not be used in.Four of sleeve pipe 2 circumference hold out against screw 4 and can clamp workpiece 8 further, to reduce the vibration of workpiece 8.
