Abstract
The utility model discloses an elastic chuck type lathe fixture which comprises a pull rod, a flange, a mandrel, a front expansion sleeve, a rear expansion sleeve, a belleville spring, a pressing plate and a nut. The mandrel is connected to the flange through a bolt, and the center line of the mandrel is provided with a through step hole. The pull rod is arranged in the step hole of the mandrel, and the front end and the rear end of the mandrel are provided with frustums. The frustum at the front end is provided with the front expansion sleeve, and the frustum at the rear end is provided with the rear expansion sleeve, the belleville spring is arranged between the front expansion sleeve and the rear expansion sleeve and on the outer portion of the mandrel, the pressing plate is assembled on the outer circle side of the pull rod and at the tail end of the rear expansion sleeve, and the nut is assembled on the outer portion of the pressing plate. The elastic chuck type lathe fixture is hydraulically controlled in the working process, manual intervention is not needed, a worker only needs to put a workpiece on the fixture, and the whole clamping and centering process can be automatically completed. The clamping efficiency is high, operation is stable, and auxiliary machining time is greatly shortened.
Description
Technical field
The utility model relates to a kind of frock clamp, relates in particular to a kind of elastic clip hair style turning attachment.
Background technology
A kind of parts that part Shi Mou automobile factory shown in Fig. 1 is conventional, it belongs to typical elongate cylinder part, an and inner step in addition, because its endoporus machines in operation in advance, like this in the time of post-production external cylindrical surface, just can not adopt again the processing of lathe chuck clamping, must adopt special frock to carry out clamping processing, also there are on the market some clamping devices for this type of elongate cylinder part, but be to be all generally the column of through hole and designing for endoporus, the elongate cylinder part that has shoulder hole for inside, seldom has applicable.Because these parts are about to produce in enormous quantities now, be badly in need of a kind of special fixture of design.
Utility model content
The utility model, for the above-mentioned state of the art, has proposed a kind of elastic clip hair style turning attachment, and this fixture convenient mounting and clamping, can improve clamping efficiency widely, and stable, and long service life has effectively reduced later stage workman's maintenance.In order to realize final purpose of the present utility model, intend adopting following technology:
A kind of elastic clip hair style turning attachment, comprises pull bar (1), ring flange (2), mandrel (3), front ringfeder (4), rear ringfeder (6), butterfly spring (5), pressing plate (7) and nut (8), wherein:
Described mandrel (3) is upper at ring flange (2) by bolt-connection, and mandrel (3) centerline is provided with the shoulder hole running through, and pull bar (1) is arranged in the shoulder hole of mandrel (3);
Described mandrel (3) front end place and rear end are provided with frustum, frustum place of front end place is fitted with front ringfeder (4), rear end frustum place is fitted with rear ringfeder (6), and between front ringfeder (4) and rear ringfeder (6), mandrel (3) outer setting has butterfly spring (5);
Described pull bar (1) cylindrical side, rear ringfeder (6) end is fitted with pressing plate (7), and pressing plate (7) outside is fitted with nut (8).
Further, described front ringfeder (4), rear ringfeder (6) are provided with the open slot of uniform arrangement, and open slot quantity is 3-6 bar.
The utility model has the advantage of: the utility model is through the exemplar processing of semi-finished product manufacturing procedure, small lot examination processing, the checking in the stages such as batch machining, prove that this fixture operation is convenient, operate steadily, machining accuracy is reliable, has greatly shortened non-cutting time, improve operating efficiency, reduced labor strength.
Brief description of the drawings
Fig. 1 is elongate cylinder part schematic diagram;
Fig. 2 is that the utility model structure is partly cutd open schematic diagram;
Fig. 3 is front ringfeder schematic diagram described in the utility model.
Detailed description of the invention
A kind of elastic clip hair style turning attachment, comprise pull bar (1), ring flange (2), mandrel (3), front ringfeder (4), rear ringfeder (6), butterfly spring (5), pressing plate (7) and nut (8), described mandrel (3) by bolt-connection on ring flange (2), mandrel (3) centerline is provided with the shoulder hole running through, pull bar (1) is arranged in the shoulder hole of mandrel (3), described mandrel (3) front end place and rear end are provided with frustum, frustum place of front end place is fitted with front ringfeder (4), rear end frustum place is fitted with rear ringfeder (6), between front ringfeder (4) and rear ringfeder (6), mandrel (3) outer setting has butterfly spring (5), described pull bar (1) cylindrical side, rear ringfeder (6) end is fitted with pressing plate (7), pressing plate (7) outside is fitted with nut (8).
The utility model operation principle is as follows: this fixture adopts hydraulic clamp mode, hydraulic cylinder drives pull bar (1) to move forward, due to the equipped pressing plate (7) of pull bar (1) cylindrical side and nut (8), rear ringfeder (6) is moved forward, rear ringfeder (6) moves forward compression butterfly spring (5), before driving, ringfeder (4) is mobile, make front ringfeder (4) and rear ringfeder (6) along mandrel (3) thus frustum surface sliding struts front ringfeder (4) and rear ringfeder (6) two ends, jam-packed workpiece (9), play the effect that centering clamps, now can start processing work (9) periphery, after workpiece (9) periphery completion of processing, hydraulic cylinder unclamps, front ringfeder (4) and rear ringfeder (6) are return under the effect of butterfly spring (5), now, take off the workpiece (9) of completion of processing, start next workpiece (9) to prepare clamping processing.
The utility model adopts hydraulic control mode in the course of the work, and without manual intervention, workman only need be placed on workpiece on fixture, and the centering of whole clamping completes automatically, and clamping efficiency is high, operates steadily, and has greatly shortened processing non-cutting time.
