Abstract

A positioning tool for machining and tensioning of a cylinder barrel comprises a cylinder body, a cylinder head, a rod body, a piston, an outer cone and an inner cone. The rod body stretches into the cylinder body through a cylinder head hole, the piston is installed in the middle of the rod body in a sleeved mode, the rod body penetrates through the rear outer end of a cylinder bottom to be connected with the inner cone, a cylinder body end face on one side of the cylinder bottom is connected with the outer cone which is of an inner cone barrel structure, and the inner conical surface of the outer cone is in sliding fit with the outer conical surface of the inner cone. Compared with the prior art, the positioning tool has the advantages that under the action of hydraulic oil, the cylinder body is pushed, then the outer conical surface of the inner cone is matched with the inner conical surface of the outer cone, accordingly the cylinder barrel is tensioned in a supporting mode, it is guaranteed that two ends can be machined simultaneously during one-time clamping, and coaxiality is guaranteed; different outer cones can be replaced according to the sizes of the diameters of cylinder barrels so that different cylinder barrels can be machined; in addition, the positioning tool is simple in structure, high in mechanized operation efficiency, reliable in performance and capable of achieving automatic clamping and machining through clamping of a hydraulic system of a machine tool.

Description

A kind of cylinder barrel processing tensioner positioning tool
Technical field
The utility model relates to hydraulic jack processing unit (plant) field, specifically a kind of positioning tool of processing cylinder barrel.
Background technology
The processing of cylinder barrel at present normally adopts the mode of folder outer tube, by the outer wall of clamp clamps cylinder barrel one end, then contrary one end is processed, but because each clamping can only be processed one end, need repeated clamping, and repeated clamping can not guarantee axiality, cause manufacturing tolerance, and multiple clamping has strengthened manipulation strength, affect operating efficiency.
Utility model content
The purpose of this utility model is exactly the defect existing for prior art, provides a kind of cylinder barrel simple in structure, easy to operate, that machining accuracy is high and working (machining) efficiency is high to process tensioner positioning tool.
The technical solution of the utility model is: comprise gray iron, the body of rod, piston, Outer Taper and inner cone; The described body of rod stretches into cylinder body by cylinder head bore and body of rod middle part is set with piston, and the body of rod connects inner cone through outer end after cylinder bottom; The cylinder body end face of described cylinder bottom one side connects Outer Taper; Described Outer Taper is inner conical-tube structure, and the inner conical surface of described Outer Taper and the male cone (strobilus masculinus) of inner cone form and be slidably matched.
Below provide a kind of concrete Outer Taper structure: described Outer Taper is axial polylith arc piece composition inner conical-tube structure, and the outer wall of inner conical-tube is provided with circumferential groove, the O type circle that in groove, installation is fixed as one polylith arc piece.
Such scheme can further be improved to:
Between described cylinder cap and cylinder body, all seal with seal between cylinder cap and the body of rod.
Described body of rod outer end is connected by being sleeved on plane bearing on the body of rod and needle bearing and inner cone, and fixes with locking nut.
The cylinder body end face of described cylinder bottom one side is provided with the plane bearing being sleeved on the body of rod.
Described arc piece is preferably three.
Compared with prior art, the utility model by promoting cylinder body, then coordinates stretching cylinder barrel by the male cone (strobilus masculinus) of inner cone and the inner conical surface of Outer Taper under the effect of hydraulic oil, can guarantee that like this clamped one time processes two ends simultaneously, thereby guarantee axiality; And can change different Outer Taper according to cylinder barrel diameter and can process different cylinder barrels.The utlity model has simple in structurely, mechanized operation efficiency is high, and dependable performance clamps by the hydraulic system of lathe, can realize automated exchanged cutter and processing.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the left view of Fig. 1; .
In figure: 1. locking nut, 2. inner cone, 3. needle bearing, 4. Outer Taper, 5. plane bearing, 6. seal, 7. cylinder body, 8. cylinder cap, 9. hold-down nut, the 10. body of rod, 11. arc pieces, 12. workpiece, 13. pistons.
The specific embodiment
Embodiment 1
With reference to Fig. 1, a kind of cylinder barrel processing tensioner positioning tool, comprise cylinder body 7, cylinder cap 8, the body of rod 10, piston 13, Outer Taper 4 and inner cone 2, concrete connected mode is as follows: the body of rod 10 stretches into cylinder body 7 by cylinder head bore and the body of rod 10 middle parts are set with piston 13, the body of rod 10 is connected with inner cone 2 by the plane bearing 5 and the needle bearing 3 that are sleeved on the body of rod 10 through outer end after cylinder bottom, and fixing with locking nut 1; The cylinder body end face of cylinder bottom one side is provided with the plane bearing 5 being sleeved on the body of rod 10, and cylinder body end face connect Outer Taper 4(Outer Taper 4 and cylinder body 7 mutually against); Outer Taper 4 is inner conical-tube structure, and the formation of the male cone (strobilus masculinus) of the inner conical surface of Outer Taper 4 and inner cone 2 is slidably matched.Between cylinder cap 8 and cylinder body 7, all seal with seal between cylinder cap 8 and the body of rod 10.During use, No. six cones of the body of rod 10 use Mohs are packed in tailstock tool, and fix with hold-down nut 9 and alignment pin, then under the effect of hydraulic oil by promoting cylinder body 7, then by the male cone (strobilus masculinus) of inner cone 2 and the inner conical surface of the Outer Taper 4 stretching workpiece 12(cylinder barrel that is slidably matched).
Embodiment 2
With reference to Fig. 1-2, a kind of cylinder barrel processing tensioner positioning tool, on the basis of embodiment 1 structure, Outer Taper 4 is selected following decision design: Outer Taper 4 forms inner conical-tube structure for axial polylith arc piece 11, and the outer wall of inner conical-tube is provided with circumferential groove, the O type circle that polylith arc piece 11 is fixed as one is installed in groove.This design is convenient takes off Outer Taper from frock, such as in the time need to changing the Outer Taper of other specifications, after cylinder body is return, each arc piece 11 taken off from O type circle respectively, then O type circle is taken off through inner cone, and convenient disassembly is quick.
