Embodiment 1: as shown in Figs. 1-5, a kind of boring grab of hydraulic fitting, including pedestal 1 is set on the pedestal 1 There are three long waist shaped mounting holes 2；It further include cylinder 3, movable plate 4 and fixture block 5；The fixture block 5 passes through four interior hexagonal countersunk head spiral shells Nail is fixedly connected on the corner of pedestal 1, and an end face of fixture block 5 is equipped with arc groove a6；The pedestal 1 is far from fixture block 5 This end is bolted or is welded with L shaped plate 9, and cylinder 3 is bolted to connection in L shaped plate 9, and cylinder 3 is parallel to L 1 side of pedestal where shape plate 9；One end of the movable plate 4 is articulated with the power output end of cylinder 3, and movable plate 4 is articulated with Pedestal 1 is equipped with arc groove b7 close to this end of fixture block 5, the other end of movable plate 4 and arc groove a6 opposite face；In this implementation In example, the end of cylinder 3 is welded with round set, and one end of movable plate 4 is equipped with threaded hole, and bolt a19 passes through circle and covers and be bolted in this The internal diameter of threaded hole, circle set is greater than the outer diameter of bolt a19, can be freely rotated along bolt a19 with circle set Subject to；This end of pedestal 1 close to fixture block 5 also is provided with threaded hole, and bolt b20 passes through the fraising on movable plate 4 and is bolted in the spiral shell Pit, the internal diameter to ream on movable plate 4 are greater than the outer diameter of bolt b20, can be turned along bolt b20 with movable plate 4 Subject to dynamic；When the cylinder 3 stretches out, arc groove b7 is close to arc groove a6 and the two merges to form through-hole；When the cylinder 3 When retraction, arc groove b7 is away from arc groove a6；1 edge of pedestal below the arc groove a6 is equipped with gap 8, and the gap 8 It tilts and extends to the direction for being away from fixture block 5.

It is receiving portion 11 that the gap 8, which is located at arc groove a6 and merges one end below the through-hole to be formed with arc groove b7, is slitted 8 inclined one end of mouth are feeding portion 10, and the size of receiving portion 11 is greater than the size of through-hole, can place public access with receiving portion 11 Subject to first 18.

The side of pedestal 1 where the inclined side in the feeding portion 10 and gap 8 forms angle α；The angle of the angle α Value is 130 ° -140 °.

The thickness of the movable plate 4 is 2.5-3.5 ㎝, and movable plate 4 is identical as 5 thickness of fixture block.

The mounting hole 2 is three long waist-shaped holes, and close to fixture block 5, this side has one, and being away from this side of fixture block 5 has two It is a.

In the present embodiment, the model SDA50X60 of cylinder 3.

The specific working principle is as follows for the present embodiment: in use, pedestal 1 is fixed in the rack of drilling machine, it is ensured that arc It is concentric that slot b7 merges the drill bit 21 to be formed on through-hole, receiving portion 11 and drilling machine with arc groove a6；Process 17 one end of pagoda head Kong Shi, operator's finger pinch pin end 18, and by pin end 18 close to feeding portion 10 to mobile at receiving portion 11 so that pagoda First 17 enter in arc groove a6, and pagoda head 17 at this time is located just at receiving portion 11；Cylinder 3 stretches out, and movable plate 4 rotates, arc After shape slot b7 pushes down pagoda head 17, operator come loose pin end 18 completion clamp, then by drill bit 21 drill；Pagoda head 17 After one end drills, cylinder 3 is retracted, and arc groove b7 is separated with arc groove a6, and the palm of operator is placed under receiving portion 11 Side, pagoda type pin end 16 are just fallen into the palm of operator.

When processing the hole of 18 one end of pin end, operator's finger pinches pin end 18, and pagoda head 17 is placed on arc groove In a6, the step between pagoda head 17 and pin end 18 is just stuck on fixture block 5；Cylinder 3 stretches out, and movable plate 4 rotates, arc groove B7 completes to clamp after pushing down pagoda head 17, then is drilled by drill bit 21；After 18 one end of pin end drills, cylinder 3 contracts It returns, arc groove b7 is separated with arc groove a6, removes pagoda type pin end 16.

Embodiment 2: the present embodiment and embodiment 1 are different, the difference is that, embodiment 1 after long-term use, arc Shape slot a6 serious wear, causes arc groove b7 to merge the drill bit 21 to be formed on through-hole, receiving portion 11 and drilling machine with arc groove a6 Decentraction influences the position of drilling, needs replacing fixture block 5 at this time, but it is excessively high to replace entire 5 cost of fixture block；And in this implementation It, can be to avoid drawbacks described above, specifically in example:

Collet 12 is removably connected on the fixture block 5, arc groove a6 is set on the collet 12；The fixture block 5 and activity The opposite face of plate 4 is equipped with notch, and collet 12 is embedded in the notch, and the two sides of fixture block 5 are equipped with threaded hole, and fastener 13 passes through Collet 12 is limited in notch by threaded hole, and the fastener 13 in this implementation is hexagon socket countersunk flat cap head screw；The present embodiment is using When, after arc groove a6 serious wear, it is only necessary to collet 12 is replaced, without replacing entire fixture block 5, save the cost.

In addition to this, the present embodiment is identical with embodiment 1, does not repeat herein.

Embodiment 3: the present embodiment is the further improvement of embodiment 2, is mainly theed improvement is that, embodiment 2 is using When, the bad installation of the pipe of spraying cooling liquid causes not cooling down when drilling；And in the present embodiment, it can be lacked to avoid above-mentioned It falls into, specifically:

Diagonal 1 side of pedestal of the fixture block 5 and upper surface are respectively equipped with inlet opening and apopore, fixed company at inlet opening It is connected to water supply connector 14, universal ring pipe 15 is bolted at apopore；When the present embodiment is in use, by water supply connector 14 and cooling Liquid case connection, the cooling of pagoda type pin end 16 when facilitating drilling.

In addition to this, the present embodiment is identical with embodiment 2, does not repeat herein.
