Abstract
The utility model relates to a cylinder car outer-circle auxiliary device which is characterized by comprising a cross bearing, a standard disc, screw bases, adjusting screws and locking nuts. The standard disc is welded at the central position of the cross bearing, an apex inner hole is arranged in the center of the standard disc, and four end portions of the cross bearing are respectively welded with the screw base, and the adjusting screw is screwed in each screw base. Top ends of the adjusting screws are used for abutting against the surface of an inner cavity of a work piece, and the locking nuts are installed on the adjusting screws. The cylinder car outer-circle auxiliary device is simple in structure, can abutt against the loose apex, is convenient to install and clamp, can be used repeatedly, and is beneficial for processing precision improvement due to the fact that the work piece and a lathe do not vibrate when the work piece is turned on the lathe.
Description
Technical field
The utility model relates to a kind of cylinder turning servicing unit, and specifically a kind of cylinder to major diameter, length length and thin-walled carries out size and adds the used servicing unit that plays the support fixation effect in man-hour, belongs to the Machining Technology field.
Background technology
In the prior art, carrying out size at the cylinder that major diameter, length length and wall are approached and add man-hour, generally is to adopt vertical lathe or large-size horizontal lathe to process.
Add man-hour with vertical lathe,, have following problem: 1, be easy to distortion during clamping, influence the cylindricity of workpiece because workpiece wall is thin.2, need the secondary clamping, influence the axiality of workpiece.3, cylindrical connects the tool marks mark, influences the roughness of workpiece.4, because Workpiece length is longer.And to consider that vertical lathe gantry shelves are highly suitable when selecting lathe for use, and there is the phenomenon of low load with strong power, influence product economy property.
Add man-hour with horizontal lathe, the servicing unit of in cylinder, will burn-oning.Have following problem: 1, each workpiece all need be used centre drill centering on servicing unit, and the axiality of centre bore and excircle of workpiece directly influences the even of workpiece.2, owing to there is the even problem of wall thickness, must increase the allowance of cylinder, waste raw material and turning man-hour.3, each workpiece all need be made servicing unit, and completion of processing also need be removed servicing unit, and the incised wound place also has soldering, problems such as lost labor and raw material.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of cylinder turning servicing unit is provided, and it is simple in structure; It can withstand on active top on; Convenient mounting and clamping can be reused, on lathe during turning; Workpiece and lathe all do not have vibration, help improving machining accuracy.
The technical scheme that provides according to the utility model: cylinder turning servicing unit; It is characterized in that: comprise cross supporting, benchmark disk, spiral shell seat, adjustment screw and locking nut; Said benchmark disk is welded on the center of cross supporting; Be provided with top endoporus at the center of benchmark disk, the spiral shell seat is welded in four end welding of said cross supporting respectively, and spiral shell is adorned an adjustment screw in each spiral shell seat; Adjustment screw end is used to withstand on the workpiece lumen surface, and locking nut is contained on the adjustment screw.
As the further improvement of the utility model, said cross supporting is welded to form by first supporting and second supporting, and said first supporting is steel plate, and second supporting is channel member, is provided with the step that is used to be adjacent to workpiece end in the end of first supporting.
The utility model compared with prior art, advantage is:The utility model is simple in structure, its can withstand on active top on, clamping is easy to adjust, can reuse, and saves adjustment, mounting or dismounting, makes, the indirect labor and the material of polishing, saves the clamping time, adjusting range is big; Good stability during cutting, during turning, workpiece and lathe all do not have vibration, and workpiece is not had any damage on lathe; Help improving machining accuracy, after the inner barrel turning, roughness can reach more than the Ra6.3; Cylindricity is less than Φ 0.1mm, and wall thickness deflection can be controlled in the 1mm, according with process requirements.The cross supporting is combined by channel-section steel and steel plate welding, loss of weight, saving cost under the prerequisite that guarantees frame for movement intensity.
Description of drawings
Fig. 1 is the structural front view of the utility model embodiment.
Fig. 2 is the structure left view of the utility model embodiment.
Description of reference numerals: the supporting of 1-cross, 1b-second supporting, 2-benchmark disk, 3-centre bore 4-spiral shell seat, 5-adjustment screw, 6-locking nut, 7-workpiece.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
Like Fig. 1, shown in Figure 2: the cylinder turning servicing unit among the embodiment mainly is made up of cross supporting 1, benchmark disk 2, spiral shell seat 4, adjustment screw 5 and locking nut 6; Said benchmark disk 2 is welded on the center of cross supporting 1; Be provided with centre bore 3 at the center of benchmark disk 2; Spiral shell seat 4 is welded in four end welding of said cross supporting 1 respectively; Spiral shell is adorned an adjustment screw 5 in each spiral shell seat 4, and adjustment screw 5 ends are used to withstand on workpiece 7 surface of internal cavity, and locking nut 6 is contained on the adjustment screw 5.
As shown in Figure 2; Among the utility model embodiment, said cross supporting 1 is welded to form by the first supporting 1a and the second supporting 1b, and the said first supporting 1a is a steel plate; The second supporting 1b is a channel member; End in first supporting is provided with the step that is used to be adjacent to workpiece 7 ends, like this under the prerequisite that guarantees frame for movement intensity loss of weight, practice thrift cost, and the location of the step of the first supporting 1a end when helping workpiece 7 clampings.
The course of work and the operation principle of the utility model are following:
With the turning servicing unit of the utility model according to inner barrel (workpiece 7) internal diameter size; Four adjustment screws 5 on the adjustment turning servicing unit; Make it to be slightly less than the inner barrel internal diameter size, the turning servicing unit is put into inner barrel one end endoporus, the inner barrel end and the second supporting 1b are adjacent to; Turn adjustment screw 5 is fixed on the inner barrel inner chamber turning servicing unit.The inner barrel that will install this servicing unit then hangs on the horizontal lathe; Inner barrel does not have an end of installation auxiliary device to be placed on the chuck (using interior pawl) of geared head; An end that installs servicing unit is towards the horizontal lathe tailstock, with the centre bore 3 on the active top jacking benchmark disk 2, with scribing block coarse adjustment inner barrel cylindrical; And then, make cylindrical shell cylindrical and horizontal lathe centre of gyration relative error value less than 0.2mm with dial gauge accurate adjustment inner barrel cylindrical.Method of adjustment is: chuck end adjustment four paws; Turning servicing unit end is adjusted four adjustment screws 5, adjusts the back with 6 lockings of four locking nuts, and servicing unit is loosening when preventing turning, adjusts the just normally turning that finishes.
