For achieving the above object, this utility model provides following technical scheme: a kind of bent axle frock clamp, including base, the V-arrangement locating piece of a pair support crankshaft center axle it is provided with on described base, on described base, corresponding locating piece side is provided with lever cylinder, described lever cylinder includes that piston and pressing plate, described pressing plate are positioned at above locating piece, and on described base, between corresponding two locating pieces, position is provided with at least one pair of location bar.

Being provided with positioning apparatus for circumferential direction on further described base, described positioning apparatus for circumferential direction includes that two spud piles, described two spud piles side in opposite directions are provided with linear hydraulic cylinder, and the axis height of described linear hydraulic cylinder is higher than crankshaft center axle.

The most described two spud pile tops are provided with guard plate, and described guard plate end is downward-sloping.

Further described base is additionally provided with accumulator, and described accumulator is connected by pipeline with lever cylinder and linear hydraulic cylinder.

Being additionally provided with reversal valve on further described base, described reversal valve is connected by pipeline with lever cylinder and linear hydraulic cylinder.

On further described base, corresponding locating piece side is provided with auxiliary and supports the support seat of bent axle, supports and is provided with support bar moving up and down on seat.

Compared with prior art, this utility model carries out just positioning by location pole pair bent axle, the central shaft enabling crankshaft two end is placed on two V-arrangement locating pieces the most accurately, the top of crankshaft center axle then it is pressed on by the pressing plate of lever cylinder, and then whole bent axle is stably fixed, wherein the linear hydraulic cylinder on two spud piles stretches out respectively and is against on the eccentric shaft of bent axle, bent axle is made fully circumferential to be fixed whole, avoid adding and rotate man-hour or mobile, bent axle alignment location bar only need to be placed on locating piece by whole fixation procedure, the follow-up work that is fixedly clamped is completely by automatically carrying out, and it is fixing relatively manual fixing more firm.

Detailed description of the invention

Referring to figs. 1 through Fig. 3, the embodiment of this utility model bent axle frock clamp is described further.

A kind of bent axle frock clamp, including base 1, the V-arrangement locating piece 5 of a pair support bent axle 2 central shaft 21 it is provided with on described base 1, on described base 1, corresponding locating piece 5 side is provided with lever cylinder 3, described lever cylinder 3 includes piston and pressing plate 32, described pressing plate 32 is positioned at above locating piece 5, on described base 1, between corresponding two locating pieces 5, position is provided with at least one pair of location bar 8, as shown in Figure 2, in the present embodiment, preferably location bar 8 is provided with two right, and has abrasionproof cushion block in locating piece 5 surface configuration.

First bent axle 2 is lifted and is made its axis to be probably directed at the straight line that two locating pieces 5 are formed during use, the most slowly put down bent axle 2, the central shaft 21 making bent axle 2 is placed on locating piece 5, and the eccentric shaft 22 of bent axle 2 puts between every pair of location bar 8, and then can prevent from bent axle 2 from occurring arbitrarily rotating, limiter slewing area, then to all lever cylinder 3 fuel feeding, make its piston driving pressing plate 32 be pressed on above the central shaft 21 of bent axle 2, by the common effect of pressing plate 32 and locating piece 5, whole bent axle 2 is precisely fixedly secured.

Being provided with positioning apparatus for circumferential direction on the preferred described base 1 of the present embodiment, described positioning apparatus for circumferential direction includes that two spud piles 6, described two spud pile 6 sides in opposite directions are provided with linear hydraulic cylinder 62, and the axis height of described linear hydraulic cylinder 62 is higher than bent axle 2 central shaft 21.After bent axle 2 is fixed by lever cylinder 3, by two linear hydraulic cylinder 62 move toward one another, all slowly at the eccentric shaft 22 of bent axle 2, until compressing, bent axle 2 is made to be fixed fully circumferential.

The most described two spud pile 6 tops of the present embodiment are provided with guard plate 63; described guard plate 63 end is downward-sloping; guard plate 63 blocks above linear hydraulic cylinder 62; put to time on locating piece 5 at bent axle 2; the eccentric shaft 22 of bent axle 2 must be by between two spud piles 6; so guard plate 63 can prevent the direct side impact linear hydraulic cylinder 62 of eccentric shaft 22 of bent axle 2, plays a protective role hydraulic cylinder, and the downward-sloping end of guard plate 63 gives bent axle 2 one guide effect.

The preferred described base 1 of the present embodiment is additionally provided with accumulator 9, described accumulator 9 is connected by pipeline with lever cylinder 3 and linear hydraulic cylinder 62, accumulator 9 is it can be avoided that lever cylinder 3 or linear hydraulic cylinder 62 rapid movement impact bent axle 2 during moment fuel feeding, and can automatically carry out pressure when lever cylinder 3 or linear hydraulic cylinder 62 insufficient pressure and supplement.

Being additionally provided with reversal valve 10 on the preferred described base 1 of the present embodiment, described reversal valve 10 is connected by pipeline with lever cylinder 3 and linear hydraulic cylinder 62, by reversal valve 10 control lever cylinder 3 and the clamping of linear hydraulic cylinder 62 or loosen, easy to use.

On the preferred described base 1 of the present embodiment, corresponding locating piece 5 side is provided with auxiliary and supports the support seat 7 of bent axle 2, support and be provided with support bar 71 moving up and down on seat 7, support bar 71 extend out to prop up bent axle 2 central shaft 21 height, it is to avoid bent axle 2 is excessive and cause locating piece 5 to deform to locating piece 5 pressure.
