Description

A kind of fixture that bores crankcase cylinder face through hole

Technical field

The utility model belongs to Workpiece clamping device, is particularly related to a kind of fixture that bores crankcase cylinder face through hole.

Background technology

Crankcase is a kind of typical box parts, and its effect is hold and support all parts in it, guarantees the tram between them, makes can turn round in phase and work each other.The machining accuracy of crankcase affects the equipment precision of inner body, and therefore, its quality, will directly determine serviceability, operating accuracy and the life-span of complete machine.The working position of crankcase relates to multiple hole and coplanar not, and the machining accuracy requiring is higher, therefore, in arranging technical process, need to be by the smart roughing operation in each main surface and hole separately.

The positioning fixture of the through hole of traditional brill crankcase cylinder face, adopts a set of one locate mode of selling, by the dead eye on crankcase and a through hole, locates, and then the cylinder hole on processing cylinder face.This locate mode built on the sand, in the process of fast punching press, the easy stressed skew of crankcase, thereby affect punching precision.

Utility model content

The purpose of this utility model is to overcome the above-mentioned defect of mentioning and deficiency, and a kind of fixture that bores crankcase cylinder face through hole is provided, accurate positioning and firm.

The technical scheme that the utility model is realized its object employing is as follows.

Bore a fixture for crankcase cylinder face through hole, comprise base, guide hole plate, guide rod and multi-shaft device; On described base, be fixedly installed locating piece and guide pillar; On described locating piece, be provided with the dead eye adapting with crankcase boss cylindrical; Described guide pillar connects guide hole plate by the first guide pin bushing; Described guide pillar connects multi-shaft device by the second guide pin bushing; On described guide pillar, be fixedly installed block; Described the first guide pin bushing is between the second guide pin bushing and block; The bottom surface of described guide hole plate is provided with alignment pin; On described multi-shaft device, be fixed with abatement; Described multi-shaft device is equipped on the output of drilling machine; Described guide rod one end is arranged in multi-shaft device, and the other end connects guide hole plate; Described leader casing is provided with spring and spring between multi-shaft device and guide hole plate.

On described base, be provided with groove, described locating piece is embedded at the groove on base.

Described guide pillar has two, and is respectively in locating piece both sides.

Described guide rod has two, and is respectively in abatement both sides.

Described abatement has four.

Setting is all erect in described guide pillar, guide rod, alignment pin and abatement.

This fixture has changed the locate mode of a traditional a set of pin, has increased cylinder-bore location on original basis, makes the contrast locating of crankcase originally more accurate, and location is firm, can effectively prevent the position skew of crankcase in process engineering.

In addition, this fixture is originally more convenient for the contrast locating of crankcase, operating personnel only need to put into locating piece Primary Location by crankcase boss cylindrical, accurate location and punching afterwards all complete automatically, not only processing dimension is more accurate, the scrappage that reduces product, has also improved operating efficiency, has reduced production cost.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Bore a fixture for crankcase cylinder face through hole, comprise base 1, guide hole plate 7, guide rod 12 and multi-shaft device 10.

On described base 1, be fixedly installed locating piece 2 and guide pillar 4; Described base 1 horizontal positioned.As preferably, on described base 1, be provided with groove, described locating piece 2 is embedded at the groove on base 1.Before work, locating piece 2 first slides and adjusts to behind appropriate location with base 1, then is screwed both.

On described locating piece 2, be provided with the dead eye 3 adapting with crankcase boss cylindrical.As shown in Figure 4, protrude at crankcase middle part is boss cylindrical.The dead eye 3 of locating piece 2 caves in, and lucky and boss cylindrical adapts.

Described guide pillar 4 connects guide hole plate 7 by the first guide pin bushing 6; Described guide pillar 4 connects multi-shaft device 10 by the second guide pin bushing 9; On described guide pillar 4, be fixedly installed block 5; Described the first guide pin bushing 6 is between the second guide pin bushing 9 and block 5; The bottom surface of described guide hole plate 7 is provided with alignment pin 8; On described multi-shaft device 10, be fixed with and write off 11; Described multi-shaft device 10 is equipped on the output of drilling machine; Described guide rod 12 one end are arranged in multi-shaft device 10, and the other end connects guide hole plate 7; Described guide rod 12 is arranged with spring 13 and spring 13 between multi-shaft device 10 and guide hole plate 7.

Described guide pillar 4 has two, and is respectively in locating piece 2 both sides.

During work, crankcase is positioned over to locating piece 2 Primary Location, then starts drilling machine, multi-shaft device 10 is descending, spring 13 compressions, thus it is descending to promote guide hole plate 7, in the cylinder-bore of alignment pin 8 insertion crankcases, accurately locates.When guide hole plate 7 touching block 5, guide hole plate 7 stops descending, and multi-shaft device 10 is under the promotion of drilling machine, still descending, writes off the action of holing of 11 pairs of crankcases.After end, guide hole plate 7 and multi-shaft device 10 are got back to original position.
