Description

A kind of modularization fixture for heavy parts clamping

Technical field

The utility model is related to machining, particularly a kind of modularization fixture for heavy parts clamping.

Background technology

In Marine Medium-speed Diesel Engine and generating are manufactured with middle high speed diesel engine, the relatively general part of its body part be compared with It is big and complicated, wherein the necessarily processing plane containing some special angles, common process mode can not cover this plane, Such case realizes the processing of these special angle planes typically all by the way of the steering of everything annex.For example, diesel oil The sleeve port plane and upper level plane of machine frame have certain angle, the position of sleeve port and main bearing hole in its plane Degree tolerance only has ± 0.05mm.

Among prior art, three kinds of methods are machined with to non-horizontal surface using common Digit Control Machine Tool：Everything annex is adjusted Angle processing, the processing of special angle annex, common Triangle wedge processing on part.

There is problems with to heavy parts special angle surface manufacturing process method in above-mentioned：

1. everything annex adjustment angle is to the machined surface of part, the everything annex of current most of lathes is to manually adjust, Its positioning precision is not ensured that, it is impossible to meet the control requirement of 0.05mm level positions precision；

2. using the processing of special angle annex, although positioning precision is higher, but cost is higher, and practicality is poor, An angle can only be used, coverage is smaller, less meets actual production demand.

3. common angle iron on part, because the angle iron volume of common integral type is larger, the calibration of upper table face is relative Trouble, and angle is single, if multiple wedge areas occupied are larger.

Utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art there is provided a kind of for heavy parts clamping Modularization fixture, realizes the processing of heavy parts special angle plane.Special tooling of the present utility model have it is easy to use, into This cheap, reliable advantage of efficiency high of getting on or off the bus, machining accuracy.

The technical solution of the utility model：

A kind of modularization fixture for heavy parts clamping, including clamping main body, angle module and pressing plate；

The rectangular triangle of clamping main body, the long side in its right angle is fixedly mounted on the table top of machining tool, the angle Degree module is bolted the hypotenuse in clamping main body, and parts to be processed is arranged on the angle module, the pressing plate peace In clamping main body, play a part of clamping parts to be processed together as clamping element with the angle module.

The wedge for also including being arranged in clamping main body lengthens module, and the wedge lengthens module and angle module and pressing plate one Play a part of to play clamping parts to be processed as clamping element.

Described clamping main body is directly installed on work top, according to the station demand of processing part, by adjusting not With angular type angle module, part is placed in module, to realize processing purpose.The angle of module can be real according to part Border processes situation to select, because module is smaller with respect to clamping body volume, it is easy to processing adjustment, handling, realizes modularization.

It is the main element for performing clamping action that described pressing plate and wedge, which lengthen module, plays control parts to be processed the The effect of six-freedom degree；The pressing plate can select different materials and quantity according to the hardness and surface appearance of parts to be processed, According to parts to be processed actual conditions whether from wedge lengthening module, increase contact area, it is ensured that the stabilization of parts to be processed Property and security.

Technological merit of the present utility model：

For the heavy parts special angle plane machining of Digit Control Machine Tool, it is installed on as frock on the work top of machine, Part is clamped on the fixture by the angle module and pressing plate of this fixture, and positioning precision ensures in the range of 0.05mm, solution Original heavy parts special angle plane surface processing method precision of having determined is not high, processing efficiency low, and labor intensity of operating staff is big Problem；Simultaneously the utility model have it is simple in construction, according to specific product situation size adjustable, easy to use, stable accuracy Reliable the characteristics of, realize the quick high accuracy processing of heavy parts special angle plane.

Embodiment

Come below in conjunction with the accompanying drawings with specific embodiment to a kind of module for clamping heavy parts of the present utility model Change fixture to be further described, but therefore should not limit protection domain of the present utility model.

It is as shown in Figure 1 for the modularization fixture schematic diagram of the present utility model for 30 ° of clamping heavy parts.Can by figure To find out, the fixture is made up of clamping main body 1, angle module 2, pressing plate 3.Described clamping main body 1 is placed in work after calibrating Make on table top, angle module 2 is bolted after clamping main body 1, part alignment to be placed on angle module 2 uses pressing plate 3 afterwards It is locked.

The schematic diagram of the modularization fixture for being used for 25 ° of clamping heavy parts for the utility model as shown in Figure 2.As schemed Show, a kind of modularization fixture for heavy parts clamping, including clamping main body 1, angle module 2, pressing plate 3 and wedge lengthen mould Block 4；The rectangular triangle of the clamping main body 1, the long side in its right angle is fixedly mounted on the table top of machining tool, the angle mould Block 2 is bolted the hypotenuse in clamping main body 1, and parts to be processed is arranged on the angle module 2, the He of pressing plate 3 Wedge lengthens module 4 and is arranged in clamping main body 1, and the wedge lengthens module 4 with angle module 2 and pressing plate 3 together as clamping Element plays a part of clamping parts to be processed.

Embodiment：To 30 ° of sleeve port plane machinings of frame in medium speed engine 16PA6STC types.
