Abstract
The utility model discloses the swollen gear shaving technology equipment of a kind of liquid, comprise body, be located at endoporus in body, it is characterized in that one end of endoporus is closed, that slides in the other end of endoporus is provided with push rod, is provided with interior hexagonal holding screw in the body on rear side of push rod by screw thread, is installed with expansion set one section of basis is external, cavity is provided with between expansion set and body, cavity is connected by more than one connecting hole with endoporus, in endoporus, connecting hole and cavity, be provided with fluid media (medium), is provided with sealing ring at push rod cylindrical; The utility model has that structure is simple, little, that long service life, working (machining) efficiency are high advantage of wearing and tearing, and reduces integrated cost.
Description
Technical field
The utility model relates to a kind of expansion tooling, especially for hydraulic expansion frock during shaving.
Background technology
At present, when carrying out shaving, the expansion tooling adopting rigidity more, it is by pulling taper expansion set with swelling workpiece, and not only structure is comparatively complicated, and wearing and tearing are large, service life is shorter, for the gear that endoporus is less, also there is the problem that difficulty of processing is large, working (machining) efficiency is low, cost is high in expansion tooling.
Summary of the invention
The purpose of this utility model is for prior art above shortcomings, provides a kind of swollen gear shaving technology equipment of liquid, and it has, and structure is simple, little, that long service life, working (machining) efficiency are high advantage of wearing and tearing, and reduces integrated cost.
For achieving the above object, liquid of the present utility model is swollen gear shaving technology equipment, comprise body, be located at endoporus in body, it is characterized in that one end of endoporus is closed, that slides in the other end of endoporus is provided with push rod, interior hexagonal holding screw is provided with by screw thread in body on rear side of push rod, be installed with expansion set one section of basis is external, cavity is provided with between expansion set and body, cavity is connected by more than one connecting hole with endoporus, in endoporus, connecting hole and cavity, be provided with fluid media (medium), be provided with sealing ring at push rod cylindrical.
During use, workpiece being placed on expansion set, making it promote pushrod advances by rotating holding screw, fluid media (medium) pressurized and extrude expansion set, expansion set distortion and swelling workpiece; Expansion set of the present utility model does not produce displacement, is flexible swelling, has that structure is simple, advantage that is little, long service life of wearing and tearing, even and if for the less workpiece of endoporus, be also convenient to processing, working (machining) efficiency be high, reduce integrated cost;
As further improvement of the utility model, one end of described endoporus is by being placed in the steel ball of port, compressing the screw closure of steel ball; Be convenient to filling and change fluid media (medium);
In sum, the utility model has that structure is simple, little, that long service life, working (machining) efficiency are high advantage of wearing and tearing, and reduces integrated cost.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, this liquid is swollen gear shaving technology equipment, comprise body 1, be located at endoporus 2 in body, one end of endoporus 2 is by being placed in the steel ball 3 of port, the screw 4 compressing steel ball is closed, that slides in the other end of endoporus 2 is provided with push rod 5, interior hexagonal holding screw 6 is provided with by screw thread in body 1 on rear side of push rod 5, expansion set 7 is installed with one section of body external welding, cavity 8 is provided with between expansion set 7 and body 1, cavity 8 is connected by several connecting hole 9 with endoporus 2, at endoporus 2, fluid media (medium) is provided with (not shown in connecting hole 9 and cavity 8, as hydraulic oil, liquid plastics), sealing ring 10 is provided with at push rod 5 cylindrical.
During use, being placed on by workpiece on expansion set 7, making it promote push rod 5 to move forward by rotating holding screw 6, fluid media (medium) pressurized and extrude expansion set 7, expansion set 7 is out of shape and swelling workpiece; Fluid media (medium) can select the larger material of viscosity, improves tension force, and cavity 8 can improve the uniformity that expansion set 7 is out of shape, and ensures tension force; Expansion set 7 of the present utility model, without the need to moving axially, has that structure is simple, advantage that is little, long service life of wearing and tearing, even and if for the less workpiece of endoporus, be also convenient to processing, working (machining) efficiency be high, reduce integrated cost; Steel ball 3 and screw 4 are convenient to filling and are changed fluid media (medium).
