Abstract

The invention relates to a cylinder outer expansion clamping fixture. The cylinder outer expansion clamping fixture comprises a fixture baseplate, a support stand plate, a fixture plate, an internal hexagonal screw, a positioning block, a pressing plate, an outer taper expansion sleeve, an inner support expansion sleeve, an inclined block, a cylinder pull rod, a fixed base, a cylinder and a guide rod; and as an inner conical surface is arranged in the outer taper expansion sleeve, an outer conical surface is arranged out of the inner support expansion sleeve, the inner conical surface of the outer taper expansion sleeve and the outer conical surface of the inner support expansion sleeve performs the taper fit, and the cylinder pull rod and the inclined block performs the horizontal reciprocating motion to push the guide rod and the inner support expansion sleeve to perform the vertical reciprocating motion, the accurate workpiece positioning is realized. The fixture has the following beneficial effects: as the taper fit is adopted, the fit precision is high, and the tool and workpiece coaxiality is guaranteed; and the fixture can satisfy the machining of workpieces with various different outer diameters by only selecting different inner support expansion sleeves according to the outer diameters of the machined workpieces, so that the application range is wide, and the interchangeability is high.

Description

Rise outside a kind of cylinder clamping device
Technical field
The invention belongs to frock clamp field, be specifically related to outside a kind of cylinder rise clamping device.
Background technology
In daily life, fixture serves vital effect during manufacturing, and its purpose is exactly the most fixing processed object, so that more stable guarantee part to be processed machining accuracy, reduce machining period, reduce enterprise's manufacturing cost, improve production efficiency.In reality, jig the most generally uses the mode of human assistance to clamp workpiece, production efficiency is low, production cost is high, therefore propose to rise outside a kind of cylinder clamping device for this shortcoming spy, automatically can be risen outward clamping workpiece, not only expand the range of lathe, it is achieved that a tractor serves several purposes, and the saving of beneficially cost.
Summary of the invention
For the limitation of the problems referred to above, it is an object of the invention to provide the clamping device that rises outside a kind of cylinder, simple in construction, with low cost, there is automatic tension device quick and easy, high efficiency.
For reaching above-mentioned purpose, the present invention adopts the following technical scheme that
Rise outside a kind of cylinder clamping device, including clamp bottom board, supporting vertical plate, jig plate, soket head cap screw, locating piece, pressing plate, outer cone ringfeder, internal stay ringfeder, skewback, air cylinder tie rod, firm banking, cylinder, guide rod;Described clamp bottom board supporting vertical plate fixed above, described jig plate is fixed in supporting vertical plate, on jig plate, fixation clip forms pressing plate combined mechanism, locating piece is arranged on pressing plate, outer cone ringfeder is fixed on jig plate by described soket head cap screw, and the inner conical surface of described outer cone ringfeder and the male cone (strobilus masculinus) of internal stay ringfeder carry out taper fit, and described cylinder is fixed on hold-down support, air cylinder tie rod connects skewback, and described skewback contacts with guide rod bottom surface, interacts.
The clamping device that rises outside cylinder designed by the present invention has only to, according to the alternative different internal stay ringfeder of the workpiece external diameter processed, can preferably realize the processing of various various outer diameter workpiece, and taper fit precision is high, it is ensured that the final crudy of product.The clamping device that rises outside designed cylinder uses the ingenious combinations such as outer cone ringfeder, internal stay ringfeder, air cylinder tie rod, cylinder, expands the range of lathe, it is achieved a tractor serves several purposes, hence it is evident that improve clamping workpiece efficiency.
Compared with prior art, the remarkable advantage of the present invention:
Rise outside the cylinder that the present invention provides clamping device, and the clamping of workpiece uses the mode of taper fit, and taper fit precision is high, and accurate positioning is reliable, and then ensure that the axiality of frock, workpiece clamping between the two.As long as this frock clamp carrys out alternative different internal stay ringfeder according to the workpiece external diameter processed just can meet the processing of various various outer diameter workpiece, taper fit precision is high, general context is wide, interchangeability is strong, service life is long, ensure that the crudy of final products, improve actual production efficiency, reduce manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of clamping device of rising outside cylinder of the present invention.
Fig. 2 is the clamping device partial structurtes schematic diagram that rises outside cylinder of the present invention.
Detailed description of the invention
With embodiment, the present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, rise outside a kind of cylinder clamping device, including clamp bottom board 1, supporting vertical plate 2,13, jig plate 3, soket head cap screw 4, locating piece 5, pressing plate 6, outer cone ringfeder 7, internal stay ringfeder 8, skewback 9, air cylinder tie rod 10, firm banking 11, cylinder 12, guide rod 14;Described clamp bottom board 1 supporting vertical plate fixed above 2,13, described jig plate 3 is fixed in supporting vertical plate 2, on jig plate 3, fixation clip 6 forms pressing plate combined mechanism, locating piece 5 is arranged on pressing plate 6, outer cone ringfeder 7 is fixed on jig plate 3 by described soket head cap screw 4, the inner conical surface of described outer cone ringfeder 7 and the male cone (strobilus masculinus) of internal stay ringfeder 8 carry out taper fit, described cylinder 12 is fixed on hold-down support 11, air cylinder tie rod 10 connects skewback 9, and described skewback 9 contacts with guide rod 14 bottom surface, interacts.Carry out taper fit by the male cone (strobilus masculinus) of the inner conical surface of outer cone ringfeder 7 Yu internal stay ringfeder 8, it is simple to being accurately positioned of workpiece to be machined (differential carrier) cylindrical, finally achieve preferable machining state.
The clamping device that rises outside above-mentioned cylinder uses process as follows:
1) first by accurate for this clamp body clamping on the workbench of Digit Control Machine Tool, check the taper seat mated condition of inner conical surface and the internal stay ringfeder 8 of outer cone ringfeder 7, the contact situation of skewback 9 and guide rod 14.
2) part (differential carrier) of processing is placed in clamp body in internal stay ringfeder 8 with excircle orientation, running cylinder promotes skewback 9 to move ahead simultaneously, realizing that skewback 9 guide rod 14 is vertical with internal stay ringfeder 8 up to move, outer cone ringfeder 7 compresses internal stay ringfeder 8 and then achieves radially locking.So far, pressing plate 6 workpiece pressing just can process workpiece smoothly.
