The auxiliary lathe machining equipment is simple in structure and good in connector fixing effect and contributes to machining the end portion of the connector through a lathe.

Description

Valve rod joint is assisted lathe machining device

Technical field

The utility model belongs to machining equipment technical field, relates in particular to the auxiliary lathe machining device of a kind of valve rod joint.

Background technology

Valve rod generally will be set for operating internal actions element on valve, as shown in Figure 1, at the front end of valve rod 3, joint 2 be set, joint 2, for affixed with the action element of valve, stirred valve rod 3 and can be realized the control and regulation to valve folding.Generally, joint 2 is to be bent into by metallic plate, forms respectively with the fastening part of bolt 1 with for the connecting portion affixed with valve rod 3 at two ends, forms regular hexagon shape for being set in the regular hexagon connecting axle of valve event element at middle part.As shown in Figure 2, the inner chamber of valve rod 3 is circular cross-section, and joint 2 to complete its end face after end welding be rectangle, cannot be inserted into valve rod 3 inside, need in advance its edge be processed, make it to meet the dimensional requirement coordinating with valve rod inwall.

Utility model content

The utility model provides a kind of valve rod joint simple in structure, that secondary process is effective auxiliary lathe machining device for solving the technical problem existing in known technology.

The utility model for the technical scheme that solves the technical problem that exists in known technology and take is: the auxiliary lathe machining device of valve rod joint comprises chuck and is positioned on described chuck the first claw and second claw at 180 °, circumferential interval, the inner at described the first claw is connected with briquetting, the inner at described the second claw is connected with connecting plate, at the middle part of described connecting plate the inner, be connected with the locating piece of regular hexagonal section, the center line of described locating piece is parallel with the center line of the second claw with described the first claw.

Advantage of the present utility model and good effect are: owing to having adopted above-mentioned design, the utility model is simple in structure.Its middle part of joint that completes welding is set on locating piece, needs the end of processing externally, regulates two claws to move to the inside, and joint is clamped between briquetting and connecting plate, can adopt afterwards the end of lathe butt joint to process, good fixing effect.
