Abstract
The utility model discloses a connecting rod turning big-head hole clamp, and relates to the technical field of machining process equipment manufacturing. The clamp comprises a clamp body provided with a small-head locating pin and a big-head supporting block, side locating blocks and side clamping devices are arranged on the portions, around the big-head supporting block, of the clamp body respectively, the side clamping devices comprise side clamping bases and side clamping blocks, wherein the side clamping blocks are movably arranged on the side clamping bases and provided with V-type working faces, and puller bolts which penetrate through the side clamping bases through threads and abut against the side clamping blocks are arranged on the side clamping bases. The included angle between the V-type working faces of the side clamping blocks is 90 degrees. Compared with the prior art, when the connecting rod turning big-head hole clamp is used for clamping a connecting rod, the connecting rod can be clamped only by tightening the puller bolts after the small-head locating pin is sleeved with the small-head hole of the connecting rod, the connecting rod can be demounted only by releasing the puller bolts, and therefore clamping and demounting time is shortened, and working efficiency is greatly improved.

Connecting rod is that two ends are hinged to transmit the rod member of motion and power with active and driven member respectively, mainly by big end, small end of connecting rod and be attached at big end and small end of connecting rod between shaft form, the enlarged head of connecting rod and little head part be not provided with initiatively or the hinged hole of driven member.Conventionally to the processing method of crank pin end pore, be: first from the enlarged head of connecting rod, radially cut as gonnecting rod body and lid; By it, the composition surface of the two processes respectively, then gonnecting rod body and cover assembling are carried out to turning processing to crank pin end pore.Big end is being combined and adding man-hour, need to big end, carry out clamping position with a kind of fixture.Existing a kind of connecting rod complex car big end hole fixture, this connecting rod complex car big end hole fixture comprises the clamp body that is provided with microcephaly's alignment pin and major part back-up block, described clamp body is equipped with respectively lid top pinching screw and two lid side pinching screws at the periphery of described major part back-up block, on the end face of nearly described major part back-up block, pressing plate is housed, described pressing plate is connected with described clamp body by end face housing screw.There is in process of production following deficiency in this connecting rod complex car big end hole fixture: when clamping connecting rod, connecting rod small end hole is inserted in after microcephaly's alignment pin, big end leans against on major part back-up block, tightens respectively four housing screws on lid top, two lid sides and pressing plate; Clamping and dismounting connecting rod need the time in second more than 20, and car closes the time that big end hole only needs second more than 10, within 1 minute, approximately can only process 2 crank pin end pores, more than 800 of split run processing crank pin end pore, inefficiency.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of clamping and the take-down time short, the connecting rod complex car big end hole fixture that efficiency is high.
In order to address the above problem, the technical solution adopted in the utility model is: this connecting rod complex car big end hole fixture, comprise the clamp body that is provided with microcephaly's alignment pin and major part back-up block, described clamp body is respectively equipped with side locating piece and side clamping device at described major part back-up block periphery.
In above-mentioned connecting rod complex car big end hole clamp technology scheme, technical scheme can also be more specifically: described side clamping device comprises side clamping seats and be actively installed on the side clamp that is provided with V-type working face on described side clamping seats, is provided with by screw thread and installed the puller bolt that side clamping seats and described side clamp connect on described side clamping seats.
Further, described side clamping seats is provided with spring spacing hole, and described side clamping seats was connected with side clamp by installing the screw that is arranged with spring of its spring spacing hole; Angle between the V-type working face of described side clamp is 90 degree.
Further, on the end face of nearly described major part back-up block one side of described side locating piece, be provided with alloy cushion block.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, clamp body is provided with microcephaly's alignment pin and major part back-up block, clamp body is respectively equipped with side locating piece and side clamping device at major part back-up block periphery, side clamping device comprises side clamping seats and be actively installed on the side clamp that is provided with V-type working face on side clamping seats, is provided with by screw thread and installed the puller bolt that side clamping seats and side clamp connect on side clamping seats.During clamping connecting rod, connecting rod small end hole is inserted in after microcephaly's alignment pin, as long as tighten puller bolt, and splits out connecting rod and also only need unclamp puller bolt, shortened clamping and take-down time, operating efficiency increases substantially.
2, clamping and needed time of dismounting connecting rod are within 10 seconds, and car closes the time that big end hole only needs second more than 10, within 1 minute, approximately can process 2.5 crank pin end pores, split run processing crank pin end pore has reached more than 1000, has improved operating efficiency approximately 20%.

The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Being illustrated in figure 1 the present embodiment needs the connecting rod of clamping position, comprises gonnecting rod body 12 and lid 13, after gonnecting rod body 12 and lid 13 combinations, has a big end hole 14, needs the hole processing.
A kind of connecting rod complex car big end hole fixture as shown in Figure 2, Figure 3, Figure 4, comprise the clamp body 1 that microcephaly's alignment pin 10 and major part back-up block 4 are housed, clamp body 1 is equipped with respectively side locating piece 3 and side clamping device at major part back-up block 4 peripheries, on the end face of side locating piece 3 nearly major part back-up block 4 one sides, be inlaid with alloy cushion block 11, side locating piece 3 is arranged on clamp body 1 by side positioning seat 2; Side clamping device comprises that side clamping seats 6 and activity are contained in the side clamp 5 with V-type working face on side clamping seats 6, and the angle between the V-type working face of side clamp 5 is 90 degree; On side clamping seats 6, be equipped with by screw thread and installed the puller bolt 7 that side clamping seats 6 and side clamp 5 connect; Side clamping seats 6 is provided with two spring spacing holes, and spring spacing hole is that aperture, top is large, the little stepped hole in aperture, bottom, and side clamping seats 6 was connected with side clamp 5 by installing the screw that is set with spring 89 of its spring spacing hole; The upper end of screw 9 has boss, and the boss of spring 8 one end and screw 9 connects, and the step surface of the other end and spring spacing hole connects.
