Abstract
The invention relates to a crankshaft clamping device of a quick dismantling slips, which comprises a clamp body, a lower slips, a gland and an upper slips, wherein grooves are respectively arranged on the clamp body and the gland, bosses are correspondingly arranged on the lower and upper slips, the lower and the upper slips are respectively and tightly matched with each other and are embedded in the grooves of the clamp body and the gland, one end of the gland is connected with one side of the clamp body through a hinged pin, the other end of the gland is provided with a U-shaped opening, a flat bolt penetrates through the U-shaped opening, is compressed and connected through a compression nut, a plurality of round holes are axially arranged at the clamp body and the inner edge of the gland, and the round holes are assembled with lifting pins of which the front parts are provided with inclined planes, and the inclined planes of the lifting pins are contacted with one sides of the bosses of the lower and the upper slips. When the crankshaft clamping device of the quick dismantling slips is used, a hammer is used for striking the lifting pins, and the slips can be quickly jacked out. The crankshaft clamping device of the quick dismantling slips has a reasonable structure, is simple to manufacture, is convenient to dismantle, has high efficiency, and is applicable to quick changeover production.
Description
Technical field
The present invention relates to the anchor clamps disassembly mechanism, but specifically a kind of bent axle clamp mechanism of quick-release slips.
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 wide in variety clamps different trunnions in order to adapt to, must change slips, unloading slips usually and all be and beaing all is the slips two ends because both cooperations are very tight, dismantle time-consuming, incompatible fast quick change product.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, make simple, convenient disassembly, the efficient height, but adapt to the bent axle clamp mechanism of the quick-release slips that fast quick change produces.
The technical scheme that the present invention solves the problems of the technologies described above employing is: but a kind of bent axle clamp mechanism of quick-release slips, it comprises clamp body, lower slips, gland, upper slips, clamp body and gland are provided with groove, lower slips and upper slips correspondingly are provided with boss, lower slips and upper slips tight fit respectively are set in the groove of clamp body and gland, gland one end links to each other with clamp body one side by hinge pin, the clamp body opposite side connects a homalocephalus nut by bearing pin, the gland other end is provided with the U-shaped mouth, the U-shaped mouth penetrates the homalocephalus nut, compress connection with clamp nut, it is characterized in that: described clamp body and gland inner edge are axially arranged with some circular holes, circular hole is equipped with the ejector pin that the front portion has the inclined-plane, and ejector pin inclined-plane and lower slips and upper slips boss one side are along contacting.
Ejector pin of the present invention is provided with positive stop lug boss, and the rear portion is the cylinder of surface band reticulate pattern.
In clamp body of the present invention and the gland circular hole ejector pin is installed, during use, the manual ejector pin rear portion reticulate pattern cylinder that grips inserts ejector pin respectively in the circular hole of clamp body and gland, and the ejector pin that strikes with a hammer can eject slips fast.Against existing technologies, the present invention is rational in infrastructure, make simply, and convenient disassembly, the efficient height adapts to fast quick change and produces, but is a kind of bent axle clamp mechanism of desirable quick-release slips.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Fig. 2 be among Fig. 1 A-A to schematic diagram.
1. clamp bodies among the figure, 2. ejector pin, 3. upper slips, 4. gland, 5. main bearing journal, 6. lower slips.
The specific embodiment
From Fig. 1, Fig. 2 as can be seen, but a kind of bent axle clamp mechanism of quick-release slips, it comprises clamp body 1, lower slips 6, gland 4, upper slips 3, clamp body 1 and gland 4 inner edges are axially arranged with groove, lower slips 6 and upper slips 3 correspondingly are provided with boss, the boss of lower slips 6 and upper slips 3 aligns and is pressed in the corresponding recesses, and lower slips 6 and upper slips 3 tight fit respectively are set on clamp body 1 and the gland 4.Gland 4 one ends link to each other with clamp body 1 one sides by hinge pin, and clamp body 1 opposite side connects a homalocephalus nut by bearing pin, and gland 4 other ends are provided with the U-shaped mouth, and the U-shaped mouth penetrates the homalocephalus nut, compresses connection with clamp nut.During use, with the hinge pin is the center, clockwise rotate and open gland 4, main bearing journal 5 just can be put into lower slips 6, rotates counterclockwise the gland 4 that closes, and upper slips 3 contacts a trunnion 5 outer round surface of being buckled, the homalocephalus nut is to the U type mouth of gland, tighten clamp nut, clamp nut compresses the homalocephalus nut, can clamp main bearing journal.Above-mentioned composition structure belongs to prior art, repeats no more.
Characteristics of the present invention are: described clamp body 1 and gland 4 inner edges are axially arranged with some circular holes, and circular hole is equipped with the ejector pin 2 that the front portion has the inclined-plane.Described ejector pin is provided with positive stop lug boss, and the rear portion is the cylinder of surface band reticulate pattern.Ejector pin 2 stretches in the circular hole, and ejector pin 2 inclined-planes and lower slips 6 and upper slips 3 boss one side are along contacting.Circular hole on said clamp body 1 and the gland 4 also cooperates with the ejector pin positive stop lug boss except playing guide effect, plays the effect that restriction ejector pin 2 moves.
When the present invention used, the manual ejector pin 2 reticulate pattern cylinders that grip inserted ejector pin 2 respectively in some circular holes of clamp body 1 and gland 4, ejector pin 2 inclined-planes align the boss one side edge of lower slips 6 and upper slips 3, when the inclined-plane was in contact with it, the ejector pin that strikes with a hammer can eject slips fast.The present invention is rational in infrastructure, makes simply, and convenient disassembly, the efficient height adapts to fast quick change and produces, but is a kind of bent axle clamp mechanism of desirable quick-release slips.
