The drilling jig is reasonable in structure, simple for manufacturing and convenient for mounting and clamping, and can realize drilling of circular holes on the clamp body and the inner edge of the gland; furthermore, the positions of the drilled holes are accurate, and the drilling jig is suitable for the quick-release slips and can be applied to quick changeovers.

Description

A kind of quick-release slips boring drill jig
Technical field
The present invention relates to anchor clamps dismounting drilling equipment, specifically a kind of quick-release slips boring drill jig.
Background technology
We know, the anchor clamps that turning or grinding crank-shaft link neck are adopted in order to improve the wearability that clamps the crank spindle neck portion, all stud with slips at the corresponding site of clamp body and gland.During installation, the boss of slips aligns to be pressed in its groove and gets final product.Yet; Because machining crankshafts is wide in variety; To clamp different trunnions in order adapting to, must to change slips, normally use oblique ejector pin the slips ejecting mechanism; This mechanism needs at the anterior pilot hole that bores of clamp body; As adopt suitable machine tooling, and need clamp body integral installation centering, time-consuming; Incompatible fast quick change produces, and manufacturing cost is also high.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art, provides a kind of rational in infrastructure, makes simply, and convenient mounting and clamping adapts to a kind of quick-release slips boring drill jig that fast quick change produces.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of quick-release slips boring drill jig, and it comprises clamp body, following lining tile, gland, goes up lining tile, lining post, bushing plate, drill bushing, and clamp body and gland are provided with groove; Following lining tile and last lining tile circumferentially correspondingly are provided with boss; Following lining tile and last lining tile tight fit respectively are set in the groove of clamp body and gland, and gland one end links to each other with clamp body one side through hinge pin, and the clamp body opposite side connects a homalocephalus nut through bearing pin; The gland other end is provided with the U-shaped mouth; The U-shaped mouth penetrates the homalocephalus nut, connects with clamp nut, clamps the lining post between following lining tile and the last lining tile; It is characterized in that: said upward lining tile, following lining tile side are provided with screw and pin-and-hole; Corresponding counterbore and the pin-and-hole of being provided with on the bushing plate, and through screw and alignment pin respectively with last lining tile, lining tile is fixed down, drill bushing is fixedly mounted on the bushing plate.
When the present invention holed, drill bit was guiding with the drill bushing, can be implemented in and axially bore some circular holes on clamp body and the gland inner edge.After boring finishes, unload bushing plate, drill bushing, open clamp nut, unload down lining tile, go up lining tile, serve as a contrast post.Then on clamp body and gland, load onto slips and lower slips, can cooperate the clamping that realizes the crank spindle footpath, carry out corresponding turning or grinding operation with other lathes.Need change when producing, the anterior ejector pin that has the inclined-plane is installed on clamp body and gland inner edge axle circular hole, ejector pin inclined-plane and upper slips and lower slips boss one side are along contacting, and the ejector pin that strikes with a hammer can eject slips fast, is suitable for the quick-release slips, soon the quick change product.Against existing technologies, the present invention is rational in infrastructure, makes simply, and convenient mounting and clamping can be implemented on clamp body and the gland inner edge and bore circular hole, and bore position is accurate, adapts to the quick-release slips, carries out fast quick change and produces.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further description.
Fig. 1 is the structural representation of confined state of the present invention.
Fig. 2 is that the A-A of Fig. 1 is to structural representation.
1. clamp bodies among the figure, 2. bearing pin, 3. homalocephalus nut, 4. clamp nut, 5. bushing plate, 6. drill bushing, 7. screw, 8. gland, 9. alignment pin, 10. lining post, lining tile on 11,12. times lining tiles, 13. hinge pin.
The specific embodiment
From Fig. 1, Fig. 2, can find out, a kind of quick-release slips boring drill jig, it comprises clamp body 1, following lining tile 12, gland 8, goes up lining tile 11, lining post 10, bushing plate 5, drill bushing 6 etc.; Clamp body 1 is provided with groove with gland 8, and following lining tile 12 circumferentially correspondingly is provided with boss with last lining tile 11, and following lining tile 12 and last lining tile 11 tight fit respectively are set in the groove of clamp body 1 and gland 8; Gland 8 one ends link to each other with clamp body 1 one sides through hinge pin 13; Clamp body 1 opposite side connects a homalocephalus nut 3 through bearing pin 2, and gland 8 other ends are provided with the U-shaped mouth, and the U-shaped mouth penetrates homalocephalus nut 3; Connect with clamp nut 4, clamp lining post 10 between following lining tile 12 and the last lining tile 11.
Characteristics of the present invention are said upward lining tiles 11, lining tile 12 sides are provided with screw and pin-and-hole down; Corresponding counterbore and the pin-and-hole of being provided with on the bushing plate 5; And passing bushing plate 5 set counterbores and pin-and-hole respectively with last lining tile 11, lining tile 12 is fixed down through screw 7 and alignment pin 9, drill bushing 6 is fixedly mounted on the bushing plate 5.The above lining tile of the present invention, down the lining tile side is provided with screw and pin-and-hole is a benchmark, confirms the drill bushing 6 and the circular hole position of boring.The position of drill bushing 6 corresponding clips concrete 1 or gland 8 is exactly the position that will hole.
The present invention will go up lining tile 11, lining tile 12 boss align the groove of pack into gland 8 and clamp body 1 respectively down, in following lining tile 12, put into lining post 10 then on the semicircle, and lining post 10 plays supporting role.Gland 8 is the center with hinge pin 13; Along rotating counterclockwise, when semicircle in the last lining tile 11 touched lining post 10, homalocephalus nut 3 was the center with bearing pin 2; Go to the upright position through gland 8 left side U-shaped mouths; Compress with clamp nut 4, bushing plate 5 and associated part promptly are in stationary state, and drill bit can drill bushing 5 be a pilot hole just.During boring, drill bit is guiding with the drill bushing, can be implemented in and axially bore some circular holes on clamp body and the gland inner edge.
After boring finishes, unload bushing plate 5, drill bushing 6, open clamp nut, unload down lining tile 12, go up lining tile 11, serve as a contrast post 10.Then on clamp body and gland, install and clamp used upper slips and lower slips, can cooperate the clamping that realizes the crank spindle footpath, carry out corresponding turning or grinding operation with other lathes.Need change when producing, the anterior ejector pin that has the inclined-plane is installed on clamp body and gland inner edge axle circular hole, ejector pin inclined-plane and upper slips and lower slips boss one side are along contacting, and the ejector pin that strikes with a hammer can eject slips fast, is suitable for the quick-release slips, soon the quick change product.The present invention bores the slips boss edge of circular hole center near subsequent installation, and assurance ejector pin inclined-plane touches and can eject slips.The present invention is rational in infrastructure, makes simply, and convenient mounting and clamping can be implemented on clamp body and the gland inner edge and bore circular hole, and bore position is accurate, adapts to the quick-release slips, carries out fast quick change and produces.
