The taper hole and the tapered groove that adopt the location gland press from both sides tightly the bulb, because the conical surface can agree with with not unidimensional bulb to consequently can press from both sides the bulb of tight multiple size, also the error of each bulb can be overcome to this device, reaches better fastening effect.
Description
Technical field
This utility model relates to a kind of drilling equipment, particularly relates to the center positioning device of a kind of shaft member.
Background technology
Ball connects the connected mode being to commonly use during shaft member connects, and is therefore required for connecting ball head in a lot of shaft member, for instance gear lever is exactly that the ball adopted connects；Owing to the rate of wear of bulb is very fast, so generally the bulb of gear lever is not one-body molded with stick, but stick with bulb for threadeding, consequently facilitating the replacing of bulb；Therefore bulb generally includes spheroid and a shorter connecting rod, and screwed hole is shot typically by the end face of connecting rod, and is positioned at connecting rod center.Restriction due to the profile of bulb, therefore it is very unlikely to be clamped, clamping mode now is typically with upper and lower mould and bulb is clamped, upper die and lower die are provided with hemisphere face, and on upper mould, it is additionally provided with a through hole, so that connecting rod inserts, simultaneously through hole coordinates with connecting rod and carries out spacing to bulb.Owing to adopting mould that bulb is clamped so that a fixture, only can be suitably used for the bulb of same size, can there is error additionally, due to each bulb, thus it sometimes appear that clamp more loose situation, vibration therefore can be made relatively big, thus mismachining tolerance also strengthens.
Utility model content
This utility model is intended to provide the center positioning device of a kind of shaft member, so that this fixture adapts to the bulb of multiple series.
The center positioning device of base case shaft member of the present utility model, including frame, drill bit and clamp system, described drill bit and clamp system are installed in frame, and drill bit is by automatic controlling system, and described automatic control system includes PLC and and gear drive；Described clamp system includes pedestal, positioning gland and location bar；Described pedestal includes mounting seat and is fixed on the sleeve pipe of mounting seat upper end；Described positioning gland is threaded in the upper end of sleeve pipe, and positioning gland be provided centrally with big end taper hole down, positioning gland upper end is additionally provided with two along the centrosymmetric blind hole of positioning gland；Described location bar is arranged on the upper end of mounting seat, and is provided with big end conical socket upward in the upper end of location bar.
In this base case, workpiece is positioned at sleeve pipe, and between positioning gland and location bar；By rotating the positioning gland of upper end, be provided centrally with taper hole due to positioning gland, so in the process that positioning gland is pressed down gradually, workpiece upper end connect axle can gradually with the center superposition of taper hole, thus by the connection shaft assignment of workpiece, and clamp；Then just workpiece can be holed.
In this programme, center positioning hole, except workpiece has clamping and positioning action, also has the effect making drill bit pass through, so that drill bit energy workpiece is holed.And the conical socket positioning the upper end of bar can make location bar and workpiece form linear contact lay, make clamping more stable, and workpiece is placed on conical socket and will not rotate, thus workpiece being had the effect of Primary Location；Therefore the taper hole on conical socket and positioning gland coordinates, and is more beneficial for the location to workpiece.Additionally bearing pin can be plugged in the blind hole on positioning gland, available lever principle rotational positioning gland, thus reaching labour-saving effect, can make again positioning gland workpiece pressing fully.
This programme adopts the conical surface that bulb is carried out spacing clamping, owing to the conical surface can agree with various sizes of bulb such that it is able to the bulb of clamping sizes, also therefore, it is possible to overcome the error of each bulb, reaches good fastening effect.
Preferred version one, as the further optimization to base case, described location bar is threaded in the upper end of described mounting seat, and the lower end of location bar is provided with a pin-and-hole；Location bar is threadeded with mounting seat, can pass through rotational positioning bar and adjust the height of the location of workpiece, so that the upper end surface of the workpiece of different size is in sustained height, with this when changing to the workpiece of different model, can drill bit be positioned 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；Owing to positioning gland and location bar are all linear contact lay with workpiece, can further workpiece be clamped so holding out against screw, to reduce the vibration of workpiece.
Preferred version three, as the further optimization to base case, the upper end of described mounting seat has some through holes, and through hole is in sleeve pipe；When workpiece is processed, have iron filings can enter in sleeve pipe unavoidably, then the some through holes in mounting seat are conducive to iron filings are cleared up.
Accompanying drawing explanation
Fig. 1 be shaft member center positioning device embodiment in the structural representation of clamp system.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: mounting seat 1, sleeve pipe 2, positioning gland 3, hold out against screw 4, location bar 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 is by automatic controlling system, automatic control system includes PLC and and gear drive.Clamp system includes pedestal, positioning gland 3, location bar 5 and holds out against screw 4.Wherein pedestal includes mounting seat 1 and is welded on the sleeve pipe 2 of mounting seat 1 upper end；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 the big end of taper hole 21 is down, positioning gland 3 is additionally provided with along the centrosymmetric blind hole of positioning gland 3, in order to rotational positioning gland 3.Location bar 5 is threaded in the upper end of mounting seat 1, and the upper end of location bar 5 is provided with conical socket 51, and the lower end of location bar 5 is provided with a pin-and-hole, to facilitate rotational positioning bar 5.Also four are had to hold out against screw 4 along the distribution of sleeve pipe 2 centrosymmetry in sleeve pipe 2 circumference.
As it is shown in figure 1, workpiece 8 is positioned at sleeve pipe 2, and between positioning gland 3 and location bar 5；By rotating the positioning gland 3 of upper end, be provided centrally with taper hole 21 due to positioning gland 3, so in the process that positioning gland 3 is pressed down gradually, workpiece 8 upper end connect axle can gradually with the center superposition of taper hole 21, thus by the connection shaft assignment of workpiece 8, and clamp；Then just workpiece 8 can be holed.
In the present embodiment, the conical socket 51 that the upper end of location bar 5 is arranged can make location bar 5 and workpiece 8 form linear contact lay, make clamping more stable, and workpiece 8 is placed on conical socket 51 and will not rotate, thus workpiece 8 being had the effect of Primary Location, taper hole 21 on conical socket 51 and positioning gland 3 coordinates, and is more beneficial for the location to workpiece 8.Additionally can pass through rotational positioning bar 5 and adjust the height of workpiece 8 position, so that the upper end surface of the workpiece 8 of different size is in sustained height, with this when changing workpiece 8, the height adjusting drill bit and the change drill bit amount of feeding can be not be used in.Four of sleeve pipe 2 circumference hold out against screw 4 and can further workpiece 8 be clamped, to reduce the vibration of workpiece 8.
