Abstract
The utility model belongs to the field of mechanical manufacturing and processing and relates to an auxiliary positioning device for processing rotators such as long shafts, long casings and the like. The auxiliary positioning device mainly comprises a companion flange connected with a three-jaw chuck, the companion flange is assembled with a tailstock mandrel by the aid of a bearing gland, and a lip-shaped seal and an O-shaped seal ring are mounted on the bearing gland. A right-end single-row deep groove ball bearing pressed by the aid of a bearing washer, the bearing washer pressed by the aid of a unidirectional thrust ball bearing, and the unidirectional thrust ball bearing pressed by a left-end single-row deep groove ball bearing are sequentially arranged on the tailstock mandrel, and the three bearings are fastened on the tailstock mandrel by the aid of round nuts and stop washers for the round nuts. Compared with a common device, the auxiliary positioning device is used without support devices such as central frames, is firm in clamping and convenient in processing, the manufacture period is shortened and processing quality is ensured.
Description
Technical field
The utility model belongs to the machine-building manufacture field, is specifically related to a kind ofly to be used for major axis, revolving body such as the body that encrusts adds the auxiliary locator in man-hour.
Background technology
Usually the processing major axis is to clamp major axis with scroll chuck on the lathe, withstands the axle head centre bore with live centre, and supports major axis with centre frame, again with an end on the lathe tool processing major axis, after machining, with the major axis clamping that turns around, the other end on the reprocessing major axis.
The processing body that encrusts is to tighten housing one end endoporus with scroll chuck on the lathe, use the centre frame support housing, again with an end on the lathe tool processing housing, after machining, with the housing clamping that turns around, reprocesses the other end on the housing.
Above-mentioned this process weak point is:
1. process major axis, need centre frame is installed on the lathe during revolving body such as the body that encrusts, processing need not to use the workpiece of centre frame to need centre frame is removed.
2. process major axis, during revolving body such as the body that encrusts owing to need the secondary clamping, cause the workpiece form and position tolerance not guarantee preferably.Usually need behind the secondary clamping to measure its form and position tolerance with specific purpose tool, to guarantee the workpiece crudy, its Measuring Time is longer, is not easy to produce in batches.
3. when processing encrusted revolving body such as body, because the workpiece cantilever is longer, processing capacity was smaller, and the machined surface roughness can not guarantee preferably.
Summary of the invention
The purpose of this utility model be propose a kind ofly to be used for major axis, the auxiliary locator of revolving body processing such as the body that encrusts, be used to solve the deficiency that above-mentioned clamping causes.
Main technical schemes of the present utility model is: major axis revolving body processing auxiliary locator mainly comprises the companion flange that scroll chuck connects, bearing gland and the tailstock mandrel assembling of companion flange by lip-type seal and O RunddichtringO are housed; Compress the single-groove grooved ball bearing of right-hand member, compress bearing washer, compress single direction thrust ball bearing by the single-groove grooved ball bearing of left end by single direction thrust ball bearing by bearing washer successively on the tailstock mandrel, three bearings are fastened on the tailstock mandrel with stop washer by round nut and round nut.
The technical problem underlying that the utility model solves is as follows:
1. adopt this auxiliary locator, need not to use centre frame, owing to adopt two scroll chuck clamping work pieces two ends, solved because of not using centre frame, the workpiece cantilever is longer, the excessive problem of centrifugal force during the rotation of workpiece top.
2. adopt this auxiliary locator, need not the secondary clamping, owing to adopt two scroll chuck clamping work pieces two ends, its machined surface is a disposal molding, can better guarantee the form and position tolerance of processing dimension; Because the scroll chuck clamping can be found pivot accurately, thereby has reduced the employed time of clamping twice, avoided checking the time of form and position tolerance.
3. adopt this auxiliary locator, because the top of the revolving bodies such as body that encrust is fixed by the another scroll chuck, machined surface all is close to scroll chuck, and cantilever is shorter, thereby can increase cutting output, better guarantees the machined surface roughness.
The utility model device is compared with common device, need not to use bracing or strutting arrangements such as centre frame, and it is firm to clamp, easy to process, reduces fabrication cycle, guarantees crudy.

In the accompanying drawing, the 1-companion flange; 2-bolt group; 3-O RunddichtringO (little); The 4-lip-type seal; 5-tailstock mandrel; The 6-tailstock; The 7-bearing gland; The 8-fastening bolt; The single-groove grooved ball journal ball of 9-; The 10-single direction thrust ball bearing; The single-groove grooved ball bearing of 11-; 12-O RunddichtringO (greatly); The 13-hexagonal spiro plug; The 14-round nut; The 15-stop washer; The 16-bearing washer; The 17-scroll chuck.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.
Embodiment: present embodiment major axis revolving body is processed the auxiliary locator general assembly drawing as shown in Figure 1:
1. single-groove grooved ball journal ball 9 is enclosed within on the tailstock mandrel 5, compresses, single direction thrust ball bearing 10 is enclosed within compresses bearing washer 16 on the tailstock mandrel 5 again, compress single direction thrust ball bearing 10 with single-groove grooved ball bearing 11 with bearing washer 16; Three bearings are fastened on the tailstock mandrel 5 with stop washer 15 with round nut 14 and round nut.
2. the tailstock mandrel 5 that three bearings will be housed is pressed on the companion flange 1, compresses with the bearing gland 7 that lip-type seal 4 and O RunddichtringO (little) 3 are housed, and finds screw accurately, screws in bolt group 2.
3. injection bearing lubricating oil is used and the hexagonal spiro plug 13 of O RunddichtringO (greatly) 12 is housed with its sealing.
4. major axis revolving body processing auxiliary locator is pressed into tailstock 6, scroll chuck 17 is loaded on the major axis revolving body processing auxiliary locator, find screw accurately, screw in bolt group 2.
Claims (1)
1. a major axis revolving body is processed auxiliary locator, and its feature mainly comprises the companion flange that is connected with scroll chuck, bearing gland and the tailstock mandrel assembling of companion flange by lip-type seal and O RunddichtringO are housed; Compress the single-groove grooved ball bearing of right-hand member, compress bearing washer, compress single direction thrust ball bearing by the single-groove grooved ball bearing of left end by single direction thrust ball bearing by bearing washer successively on the tailstock mandrel, three bearings are fastened on the tailstock mandrel with stop washer by round nut and round nut.
