Abstract

The utility model discloses a processing fixture of an engine body, which comprises a fixture body. Both front and rear sides of both ends of the fixture body are fixedly provided with upright posts; the top ends of the upright posts are provided with a cylinder base; both ends of the cylinder base are respectively provided with cylinders; pressure plates are fixed at the bottom ends of cylinder piston rods; both side walls of the lower end of the fixture body are respectively provided with shaft seats; a rotating shaft is rotationally arranged between the two shaft seats; a supporting sleeve is fixed outside the rotating shaft; the supporting sleeve is movably connected with a positioning pin which is matched with a positioning hole on the lower end face of the processed engine body; the left end of the rotating shaft is provided with a pin hole which is internally provided with an inserted pin; and the pressure plates fixed at the bottom ends of the cylinder piston rods are pressed against the upper end face of the processed engine body. In the utility model, the processing fixture has simple structure; the variety of an engine body production line can be rapidly, conveniently and simply replaced, and the same production efficiency is achieved; and the processing fixture is suitable for mass production.

Description

The clamp for machining of engine body

Technical field

The utility model relates to the anchor clamps that a kind of body face processing is adopted, and mainly is a kind of clamp for machining of engine body.

Background technology

Domestic existing diesel-engine body special plane clamp for machining all can only be realized the body processing of single series of products, now market is changeable to product demand, diesel engine industry is risen one after another often, sometimes certain type output is very big, sometimes be in end-of-life state, this the very strong production line of intrinsic product dependence is difficult to survive in intense market competition, not only causes the waste of resource, and cause very big investment risk.For this reason, need organic clamp for machining can adapt to series how wide in variety engine body process.

The utility model content

Technical problem to be solved in the utility model provides a kind of clamp for machining of engine body, and it is simple in structure, can change body production line kind quick, convenient, simply and reach identical production efficiency to adapt to production in enormous quantities.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of clamp for machining of engine body, include clamp body, the front and back side at clamp body two ends all is installed with column, on the top of described column cylinder seat is installed, the two ends of described cylinder seat are separately installed with cylinder, and the bottom of cylinder piston rod is fixed with pressing plate; Be separately installed with axle bed on the two side of described clamp body lower end, be rotatablely equipped with rotating shaft between two axle beds, rotating shaft is fixed with support set outward, be connected with alignment pin on the described support set, described alignment pin matches with locating hole on the processed body lower surface, the left end of described rotating shaft has pin-and-hole, is provided with latch in the pin-and-hole; The fixing pressing plate in described cylinder piston rod bottom is against on the upper surface of processed body.

The right-hand member of described clamp body is slidingly fitted with slide plate.

The utility model is with body bottom surface and two fabrication holes location, non-machined surface clamps, change the different alignment pins and the slide plate of differing heights according to different kind type, select or change cutterhead to satisfy different body processing requests according to the size of different cultivars body milling area.

Operation principle of the present utility model is: body pushes in the clamp body by slide plate, rotating shaft, alignment pin inserted location, body locating piece hole when support set forwarded peak to, and cylinder drives pressing plate and clamps body, when rotating shaft was rotated away from peak, alignment pin detached from locating hole.

Only need change alternate products alignment pin and slide plate when changing product variety in the utility model gets final product.

The utility model has the advantages that:

The utility model is simple in structure, can change body production line kind quick, convenient, simply and reach identical production efficiency to adapt to production in enormous quantities.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Referring to Fig. 1, a kind of clamp for machining of engine body includes clamp body 1, the front and back side at clamp body 1 two ends all is installed with column 2, cylinder seat 3 is installed on the top of described column 2, and the two ends of described cylinder seat 3 are separately installed with cylinder 4, and the bottom of cylinder 4 piston rods is fixed with pressing plate 5; Be separately installed with axle bed 6 on the two side of described clamp body 1 lower end, be rotatablely equipped with rotating shaft 7 between two axle beds 6, the rotating shaft 7 outer support sets 8 that are fixed with, be connected with alignment pin 9 on the described support set 8, described alignment pin 9 matches with locating hole on processed body 12 lower surfaces, the left end of described rotating shaft 7 has pin-and-hole, is provided with latch 11 in the pin-and-hole; The fixing pressing plate 5 in described cylinder 4 piston rod bottoms is against on the upper surface of processed body 12.

The right-hand member of described clamp body 1 is slidingly fitted with slide plate 13.
