The tool comprises an expansion sleeve, a taper shank shaft and a pull rod, wherein the pull rod penetrates through a hollow spindle of a machine tool; one end of the pull rod is connected with a piston of a telescopic cylinder fixed on the machine tool, and the other end of the pull rod stretches out of the hollow spindle and is connected with the taper shank shaft; the expansion sleeve is sleeved on the pull rod; and the taper surface of the taper shank shaft is in sliding fit with the expansion sleeve. By the tool, the labor intensity of workers is reduced, the production efficiency of the machine tool is improved, and the machining accuracy of a workpiece can be effectively ensured.
Description
Technical field
The utility model relates to a kind of fixture, particularly a kind of clamping tool of cylinder sleeve processing.
Background technology
The cylinder sleeve of engine belongs to thin-wall workpiece, the outer wall of the cylinder sleeve of engine that especially has forms some burrs, be unfavorable for that when machined clamping fixes, and the poor rigidity of thin-wall workpiece, if adopt traditional clamping tooling to clamp workpiece, owing to there is no locating surface, be inconvenient to clamp, need again manually fixing during the workpiece of processing different size, cause the lathe working (machining) efficiency low, workpiece is subjected to the effect of cutting force and clamping force very easily to produce deformation in turning process, affects dimensional accuracy and the form accuracy of workpiece.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of clamping tool of cylinder sleeve processing is provided, and has reduced workman's labour intensity, has improved the production efficiency of lathe, can effectively guarantee the machining accuracy of workpiece.
The technical solution of the utility model is: a kind of clamping tool of cylinder sleeve processing, comprise ringfeder, taper-shank arbor, pull bar, described pull bar passes the hollow spindle of lathe, one end is connected with the piston of telescopic cylinder on being fixed on lathe, the other end of pull bar is overhanging to be gone out hollow spindle and is connected with taper-shank arbor, the ringfeder empty set is on pull bar, and the conical surface and the ringfeder of described taper-shank arbor are slidably matched.
Described taper-shank arbor is provided with shoulder hole vertically, is provided with annular slot in shoulder hole.
One end of described pull bar is provided with annular groove.
Adopt technique scheme: pull bar passes the hollow spindle of lathe, one end is connected with the piston of telescopic cylinder on being fixed on lathe, the other end of pull bar is overhanging to be gone out hollow spindle and is connected with taper-shank arbor, the ringfeder empty set is on pull bar, the conical surface and the ringfeder of described taper-shank arbor are slidably matched, by the operation telescopic cylinder, can reduce labour intensity, improve machine tooling efficient, the piston driving taper-shank arbor moves in ringfeder, and the conical surface radially pushes ringfeder, makes radially swollen rising of ringfeder, the tensioner cylinder sleeve effectively guarantees element precision.
Be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that pull bar coordinates schematic diagram with taper-shank arbor.
In accompanying drawing, 1 is lathe, and 2 is telescopic cylinder, and 3 is ringfeder, and 4 is taper-shank arbor, and 41 is the conical surface, and 42 is shoulder hole, and 43 is annular slot, and 5 is pull bar, and 51 is annular groove, and 6 is tracheae, and 7 is reversal valve, and 8 is air valve, and 9 is hollow spindle.
The specific embodiment
Referring to Fig. 1, Fig. 2, a kind of clamping tool of cylinder sleeve processing comprises ringfeder 3, taper-shank arbor 4, pull bar 5.Described pull bar 5 passes the hollow spindle of lathe 1, one end is connected with the piston of telescopic cylinder 2 on being fixed on lathe, the present embodiment, telescopic cylinder 2 is the double-piston rotary cylinder, telescopic cylinder is bolted on the main-gear box of lathe, and the cylinder body of telescopic cylinder is connected with tracheae 6, and tracheae 6 is provided with air valve 8 and reversal valve 7, reversal valve 7 adopts solenoid directional control valve, and reversal valve is connected with the reversal valve gauge tap.Pull bar 5 can be connected by the piston of bolt with telescopic cylinder 2, also can be connected by the piston of alignment pin with telescopic cylinder 2, and the present embodiment, an end of pull bar 5 is connected by the piston of bolt with telescopic cylinder 2.The other end of pull bar 5 is overhanging to be gone out hollow spindle 9 and is connected with taper-shank arbor 4, the present embodiment, the other end of pull bar 5 is provided with annular groove 51, taper-shank arbor 4 is provided with shoulder hole 42 vertically, be provided with annular slot 43 in shoulder hole 42, pull bar 5 is stuck on annular groove 51 by snap ring and is located by connecting with taper-shank arbor 4, and pull bar 5 also can be connected by screw thread or bolt with taper-shank arbor 4.Ringfeder 3 empty sets are provided with opening vertically on described ringfeder on pull bar 5, the conical surface 41 and the ringfeder 3 of described taper-shank arbor 4 are slidably matched.
During use, tracheae 6 connects source of the gas, open air valve 8, by manually cylinder sleeve being enclosed within on ringfeder 3, control by controlling the reversal valve gauge tap piston-retraction that reversal valve 7 is controlled telescopic cylinder 2, piston driving pull bar 5 moves to the direction of telescopic cylinder 2 cylinder bodies, pull bar 5 drives taper-shank arbor 4 and moves, the conical surface 41 of taper-shank arbor radially pushes ringfeder 3, ringfeder 3 is subject to power radially, makes radially swollen rising of ringfeder 3, the cylinder sleeve of expansion sleeve on the ringfeder circumference, make cylinder sleeve be fixed on the ringfeder circumference, be convenient to processing.After machining, control by controlling the reversal valve gauge tap piston elongation that reversal valve 7 is controlled telescopic cylinder 2, the direction that piston driving pull bar 5 deviates from telescopic cylinder 2 moves, the inclined-plane of taper-shank arbor breaks away from ringfeder, ringfeder 3 is radially dwindled, and cylinder sleeve does not stress, and can take off cylinder sleeve.
The utility model drives pull bar by telescopic cylinder and pulls taper-shank arbor, and is simple to operate, be convenient to realize automation, greatly alleviated artificial labour intensity, by the radially swollen tensioner cylinder sleeve of ringfeder, the assurance clamping is stable, and cylinder sleeve axle and port axiality are high, effectively guarantee the machining accuracy of workpiece.
