The utility model discloses reduce the consumption of manpower, shortened operating time, improved work efficiency, reduced the manufacturing cost of user unit.
Description
Technical field
This utility model relates to a kind of machining frock, is specifically related to the expansion of a kind of novel internal diameter and clamps frock.
Background technology
At present, interior hole machined of the prior art, it mostly is and directly clamps with lathe dog, damage frock sometimes, cause the waste of material, and exist fixing insecure, the quality of impact processing, and clamp trouble, waste time and energy, reduce work efficiency, add production cost.
Summary of the invention
The purpose of this utility model is to provide a kind of novel internal diameter to expand to clamp frock.
For achieving the above object, the technical solution of the utility model is: the expansion of a kind of novel internal diameter clamps frock, including expansion sleeve, pull bar and skewed boss, pull bar it is interspersed with inside expansion sleeve, one end of the internal inserting hole of described expansion sleeve is taper, expansion sleeve outer wall is provided with skewed boss, one end is that the expansion sleeve outer wall of taper is all divided into four parts, spacing cavity it is provided with inside expansion sleeve, spacing cavity side is provided with spring washer, described pull bar outer wall is provided with limited block, one end of pull bar is taper, the taper of pull bar one end matches with the taper inserting hole within expansion sleeve, the other end of described pull bar is connected with oil cylinder, chimeric flexible device in described skewed outer wall of boss, the outer wall surface of skewed boss is provided with anti-slip veins
Owing to using technique scheme, the beneficial effects of the utility model:
1, this utility model is provided with anti-slip veins, increases the friction with workpiece, it is therefore prevented that workpiece skids off from expansion sleeve.
2, this utility model is provided with elastic device, can bounce back by ancillary oblique shape boss, prevents the used time longer skewed boss deformation caused.
3, this utility model is provided with spring washer and limited block, serve buffering and spacing effect, it is to avoid the most too much and the device caused damages, reduce the production cost of Subscriber Unit.
4, this utility model is provided with oil cylinder, decreases the consumption of manpower, shortens the working time, improves work efficiency.
Accompanying drawing explanation
In conjunction with accompanying drawing, this utility model is described further.
Fig. 1 is structural representation of the present utility model.
In figure: 1, expansion sleeve, 2, pull bar, 3, skewed boss, 4, spacing cavity, 5, elastic washer, 6, limited block, 7, oil cylinder, 8, elastic device, 9, anti-slip veins.
Detailed description of the invention
As shown in Figure 1, the technical solution adopted in the utility model is: the expansion of a kind of novel internal diameter clamps frock, including expansion sleeve 1, pull bar 2, skewed boss 3, pull bar 2 it is interspersed with inside expansion sleeve 1, one end of the internal inserting hole of described expansion sleeve 1 is taper, expansion sleeve 1 outer wall is provided with skewed boss 3, one end is that expansion sleeve 1 outer wall of taper is all divided into four parts, spacing cavity 4 it is provided with inside expansion sleeve 1, spacing cavity 4 side is provided with spring washer 5, described pull bar 2 outer wall is provided with limited block 6, one end of pull bar 2 is taper, the taper of pull bar 2 one end matches with the taper inserting hole within expansion sleeve 1, the other end of described pull bar 2 is connected with oil cylinder 7, chimeric flexible device 8 on described skewed boss 3 outer wall, the outer wall surface of skewed boss 3 is provided with anti-slip veins 9.
Pass through arrangement above, operation principle of the present utility model is: this utility model clamps processing for lathe to the support of inner hole of workpiece, skewed boss 3 is inserted in the workpiece needing processing, oil cylinder 7 pulls pull bar 2, make the limited block 6 on pull bar 2 can only arrive spring washer 5, spring washer 5 also plays cushioning effect simultaneously, prevent the device damage firmly too much caused, due to pulling of oil cylinder 7, skewed boss 3 on expansion sleeve 1 is made to be fully contacted with the inwall of inner hole of workpiece, workpiece support is fixedly clamped, just can be processed.
Claims (1)
