Abstract

The invention belongs to the technical field of processing machine tools and concretely relates to diesel-engine double-cylinder box-body equipment. The diesel-engine double-cylinder box-body equipment comprises an installing plate, wherein the installing plate is fixedly arranged on an equipment table, and precasting holes are then positioned by utilizing three cylinder-jacking devices, thus, the position of a box body can be accurately positioned; and the position precision of the box body is then further positioned by utilizing a limiting device on the installing plate, and meanwhile, errors which are generated due to vibration when the box body is processed can also be decreased. Thus, the box body can be fixed by processing a plurality of holes and only rotating the equipment table.

Description

Twin-tub casing frock

Technical field

The invention belongs to the machining tool technical field, be specifically related to a kind of frock of diesel engine twin-tub casing.

Background technology

At present, when processing diesel engine twin-tub casing, adopt the most original repeatedly processing mode of location, hole of every processing, just necessary clamping, the casing in location.The processing of twin-tub box body hole simultaneously is more, so just causes multiple clamping, and the mismachining tolerance of accumulative total is big, finally influences the precision of casing.

Summary of the invention

The present invention provide a kind of can one-time positioning, the twin-tub casing frock of processing repeatedly.

In order to solve the problems of the technologies described above, the present invention provides following technical scheme: twin-tub casing frock, comprise installing plate, and installing plate is fixed on the tooling platform that circles round, and described installing plate is provided with three cylinder holding devices, and installing plate is provided with stopping means.

Adopt technique scheme; Among the present invention; Installing plate is fixed on the tooling platform, then precast hole is utilized three cylinder holding device location, can accurately locate the position of casing like this; Utilize stopping means on the installing plate further to locate the positional precision of casing again, can also reduce casing simultaneously and add the error that produce because of vibrations man-hour.Static housing just can be processed a plurality of holes like this, only needs the rotary tooling platform just passable.

Further, described stopping means comprises limited block and limited post, and limited block is arranged on one group of relative edge, prevents that casing from moving on the plane that adds man-hour, and limited post is arranged on other one group of relative edge, prevents that casing from adding the play up and down in man-hour.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation:

Fig. 1 is the structural representation of twin-tub casing frock of the present invention;

Fig. 2 is the vertical view of twin-tub casing frock of the present invention.

The specific embodiment

Like Fig. 1, shown in 2: twin-tub casing frock; Comprise installing plate 1, installing plate 1 is fixed on the tooling platform that circles round, and described installing plate 1 is provided with three cylinder holding devices 2; Installing plate 1 is provided with stopping means; Stopping means comprises limited block 4 and limited post 3, and limited block 4 is arranged on one group of two opposite edges along last, and limited post 3 is arranged on other one group of two opposite edges along last.

Adding man-hour; Earlier installing plate 1 is fixed on the tooling platform, then precast hole is utilized three cylinder holding devices, 2 location, can accurately locate the position of casing like this; Utilize stopping means on the installing plate 1 further to locate the positioning accuracy of casing again; The while stopping means can also reduce casing and add the error that produce because of vibrations man-hour, and limited block 4 is arranged on one group of two opposite edges along last, prevents that casing from moving on the plane that adds man-hour; Limited post 3 is arranged on other one group of two opposite edges along last, prevents that casing from adding the play up and down in man-hour.Static housing only needs the rotary tooling platform just can process a plurality of holes like this.

Cylinder holding device 2 of the present invention also is provided with corollary apparatus such as alignment pin, guide finger.

Above-described only is preferred implementation of the present invention; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement; These also should be regarded as protection scope of the present invention, and these can not influence effect and practical applicability that the present invention implements.
