Abstract
The utility model discloses a novel self-centering cylinder sleeve clamp which comprises a tapered clamping core rod, wherein a mounting plate is arranged on one side end part of the tapered clamping core rod; a plastic expansion sleeve is arranged on the tapered clamping core rod and used for tightening and fixing the inner wall of a cylinder sleeve in matching with the tapered clamping core rod; spring ring grooves are formed on the plastic expansion sleeve; and an annular return spring is mounted in the spring ring grooves. The novel self-centering cylinder sleeve clamp has a simple structure, is convenient to operate and ensures high machining precision of clamped products; plastic is adopted at the contact part of the novel self-centering cylinder sleeve clamp and the inner wall of a cylinder sleeve, so as to avoid the problems of crushing and scratching in the clamping process; and meanwhile, cylinder sleeve products clamped by the novel self-centering cylinder sleeve clamp do not need to be calibrated before being processed, and the clamping efficiency is high.
Description
Technical field
The utility model relates to a kind of clamp tool, is specifically related to a kind of anchor clamps that are used for the processing of cylinder sleeve series products.
Background technology
Cylinder sleeve is an important spare part in the engine, and in the working environment of high temperature, it is bearing the round fricting movement of piston ring, therefore requires it that good resistance to wearing and the tired performance of high temperature resistance arranged.In order to guarantee that cylinder sleeve has good resistance to wearing and the tired performance of high temperature resistance, its surface can not be scratched, otherwise will cause sharply descend the service life of cylinder sleeve.In addition, also require cylinder sleeve and piston ring to have good cooperating, otherwise it is bad to cause in the engine operation that gas leakage or piston difficulty etc. take place, so cylinder sleeve require to have higher precision and guarantee the stable of work.
But in traditional the clamping in the process of cylinder sleeve; It adopts traditional chuck mode clamp tool; In clamping process, deform owing to the excessive cylinder sleeve that causes easily of clamping pressure, and chuck mode clamping location is accurate inadequately, the converted products axiality is overproof; Cause product to crush problems such as scuffing in the clamping easily.Simultaneously, these traditional chuck mode anchor clamps are owing to before each cylinder sleeve product processing, can process after all will calibrating the product behind the clamping, and production efficiency is low, can not adapt to the production in enormous quantities needs of cylinder sleeve.
The utility model content
The purpose of the utility model is to the problems referred to above weak point; A kind of easy to operate, self-centering cylinder sleeve anchor clamps that clamping precision is high are provided, and it solves, and existing clamping cylinder sleeve process causes that product crushes, scuffing and clamping converted products axiality is poor, production efficiency is low problem.
Novel self-centering cylinder sleeve anchor clamps comprise that a side end is provided with the taper clamping plug of mounting disc, and said taper clamping plug is provided with one and cooperates the plastic cement expansion set that is used for urgent fixedly inboard wall of cylinder liner with it.
As preferably, above-mentioned plastic cement expansion set is provided with the spring annular groove, and this spring annular groove is equipped with annular returning spring.
Further, above-mentioned plastic cement expansion set is provided with at least one the groove that splits, and as preferably, above-mentioned plastic cement expansion set is provided with three the groove that splits.
As preferably, above-mentioned plastic cement expansion set outer tube diameter under normal conditions than caliber in the cylinder sleeve little 3 to 6mm.
The utility model is simple in structure, and is easy to operate, and the clamping processing precision of products is high, and the utility model and inboard wall of cylinder liner contact site are plastic cement, thereby crushing of having avoided taking place in the clamping process, scuffing problem; Simultaneously, the utility model clamping cylinder sleeve product need not be calibrated every product before processing, and clamping efficient is high.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 gets into cylinder sleeve inner structure sketch map for the utility model.
Below come the utility model is further described through the accompanying drawing and the specific embodiment:
The specific embodiment
As illustrated in fig. 1 and 2, the described novel self-centering cylinder sleeve anchor clamps of the utility model comprise that a side end is provided with the taper clamping plug 1 of mounting disc 11, and said taper clamping plug 1 is provided with one and cooperates the plastic cement expansion set 2 that is used for urgent fixedly cylinder sleeve 3 inwalls with it.
Above-mentioned plastic cement expansion set 2 is provided with spring annular groove 21, and this spring annular groove is equipped with annular returning spring (not drawing among the figure).
Further, above-mentioned plastic cement expansion set 2 is provided with at least one the groove that splits, as preferably, above-mentioned plastic cement expansion set 2 be provided with three split groove (not drawing among the figure).
As preferably, above-mentioned plastic cement expansion set 2 outer tube diameter under normal conditions than calibers little 3 in the cylinder sleeve 3 to 6mm.
Below come the utility model is further described through concrete application principle:
The described cylinder sleeve anchor clamps of the utility model are installed in fit applications such as external equipment such as cylinder group through mounting disc, existing being used with the utility model and cylinder is that example specifies its application principle, and at first the utility model is fixed on mounting disc 11 on the pull bar of cylinder through screw; (arrow representes to receive force direction among the figure) as shown in Figure 2; Utilize cylinder to insert the cylinder sleeve 3 that vertical pendulum is placed on brace table 4 to the taper clamping plug 1 that has plastic cement expansion set 2, cylinder inserts cylinder sleeve 3 continued to taper clamping plug 1 and pushes downwards, and plastic cement expansion set 2 under the conical surface dual compression of brace table 4 and taper clamping plug 1, produces outside bloated elastic deformation; Plastic cement expansion set 2 tops outwards enlarge from splitting groove; Thereby cause its diameter to become big, under the downward extruding of cylinder, the diameter of plastic cement expansion set 2 swells urgent fixing as for cylinder sleeve 3 inwalls always; Through the garment bag 2 urgent interference fit with cylinder sleeve 3 inwalls that swells; Realization is to the clamping of cylinder sleeve 3, and the customized heart makes things convenient for the maintain and replace and the processing of cylinder sleeve.Because garment bag its diameter in the process that is extruded evenly swells, thereby the cylinder sleeve of its clamping provides the yield rate of cylinder sleeve, economical with materials in that to add the man-hour axiality high.After the cylinder sleeve completion of processing; Its pull bar of cylinder drive is shunk back and is upwards carried; Taper clamping plug 1 relative plastic cement expansion set 2 upwards slides certain distance no longer to its extruding; Plastic cement expansion set 2 is under the restoring force of annular returning spring, and diameter narrows down to normal nature gradually, and can conveniently unload cylinder sleeve 3 this moment.
