Specific embodiment
Embodiment 1
As shown in Figure 1-3, a kind of quickly beat both ends center aperture apparatus comprising work top 1, slide plate 2,3 and of clamp body
Two centre drilling devices.The work top 1 is located in rack 8, in this way convenient for operating, in 1 length direction of work top
Between offer step groove 11, the length of step groove 11 is less than the length of work top 1.2 frame of slide plate on the step of step groove 11,
End face jockey body 3 thereon, lower end surface connect driving device, and driving device can be hydraulic cylinder, can be belt transmission.
The present embodiment driving device includes rack gear 51 and gear 2), rack gear 51 is fixed on the lower end surface of slide plate 2, rack gear 51
Tooth is meshed with gear 52 below, and gear 52 is mounted on gear shaft 53, and gear shaft 53 passes through bearing (not shown)
The two sides of step groove 11 are fixed on, in this way, the clamp body 3 on slide plate 2 can be driven along workbench when gear 52 rotates
1 length direction of face is mobile.
53 one end of gear shaft stretches out 1 side of work top and connects handwheel 54, in this way rotation handwheel 54, and gear 52 can just revolved
Turn, so that clamp body 3 be made to move along 1 length direction of work top.In order to facilitate rotation handwheel 54, handwheel 54 is connected with handle
541。
Centre drilling device includes motor 41 and centre drill 42, and motor 41 is fixed on the two of the step groove 11 of work top 1
End, spindle end are equipped with centre drill 42, and two centre drilling devices are located at 3 length direction of clamp body and are arranged oppositely, i.e., in
The heart bores 42 both facing to clamp body 3, makes the centre drill 42 of centre drilling device on the same axis.
It is unstable when slide plate 2 is moved along step groove 11 in order to prevent, influence the essence of the workpiece centering on clamp body 3
Degree, is pressed with pressing plate 21 along 11 length direction of step groove in 2 upper surface of slide plate, and pressing plate 21 is bolted on work top 1,
The slide plate 2 that pressing plate 21 is pushed down can move under the drive of rack gear 51 along 1 length direction of work top.
In order to be better secured to special-shaped workpiece on clamp body 3,3 upper surface of clamp body is set along 11 length direction of step groove
There is U-type groove 31, the size of U-type groove 31 and the size of special-shaped workpiece axis match, and U-type groove 31 is lower than far from the upper surface of handwheel 54
Its another upper surface, as shown in Fig. 2, the upper end right side of i.e. U-type groove 31 is lower than left side；In 1 upper surface U-type groove of work top
31 right side is connected with support portion 6, and 6 top of support portion is equipped with inclined-plane 61 outwardly, so special-shaped workpiece close to 3 side of clamp body
Axis be placed in the U-type groove 31 of clamp body 3, heteromorphism part can lean against on the inclined-plane 61 on 6 top of support portion.
In order to prevent special-shaped workpiece from moving axially in punching, limited block is connected in 3 length direction both ends of the surface of clamp body
7, the length of preferred fixture body 3 is just consistent with special-shaped workpiece length at this time, and limited block 7 blocks 31 bottom part down of U-type groove, in this way
It will not interfere with centering, by the limited block 7 at both ends, the axial direction of special-shaped workpiece can be stuck in U-type groove 31, raising is hit
Heart hole precision.
In use, special-shaped workpiece axis is put into the U-type groove 31 of clamp body 3, axis both ends are limited block 7 and block, heteromorphism part
Divide on the inclined-plane 61 for leaning against support portion 6, start motor 41, drives the centre drill 42 on 41 main shaft of motor to rotate, shake handwheel 54,
Band moving gear 52 rotates, and so that clamp body 3 is driven special-shaped workpiece shaft end, one end centre drill 42 is close thereto, drills out centre bore, instead
To handwheel 54 is shaken, other end centre bore just can be drilled out.
Above-described embodiment is the preferable implementation of the utility model, and in addition to this, the utility model can also be with other
Mode realizes that any obvious replacement is in the protection of the utility model under the premise of not departing from the technical program design
Within the scope of.
