Abstract

The invention discloses a lathe for machining the sealing surfaces of a gate valve. The lathe comprises a turntable coaxially fixed with a spindle, and a turning tool arranged on a tool apron, wherein the turntable is provided with a fixture for fixing a valve body; and the turning tool consists of a tool bar and a tool bit fixed on the tool bar along the radial direction. The valve body is not required to be turned when the two sealing surfaces of the gate valve are machined by the lathe, and the two sealing surfaces of the gate valve can be machined only by moving the turning tool, so that production efficiency is improved.

Description

A kind of lathe that is used to process the slide valve sealing surface
Technical field
The present invention relates to a kind of equipment that is used for metal processing, relate in particular to a kind of lathe that is used to process the slide valve sealing surface.
Background technology
The position that valve body and valve plate are sealed and matched is a sealing surface, and the sealing surface of slide valve is owing to need be sealed and matched with the edge, two sides of valve plate, so sealing surface is two ring surfaces that are parallel to each other.
In the prior art processing slide valve sealing surface the time, can utilize engine lathe, valve body is fixed on the lathe spindle, utilize cutter at first to process one of them sealing surface, valve body then takes off and overturns, utilize cutter to process another sealing surface again, be equivalent to two procedures, reduced the efficient of valve body processing.
Summary of the invention
The invention provides lathe a kind of simple in structure, easy to use, when two sealing surfaces of processing slide valve, need not the valve body that overturns, only just can finish the processing of two sealing surfaces, improved production efficiency by the motion of cutter.
A kind of lathe that is used to process the slide valve sealing surface, comprise and co-axially fixed rotating disk of main shaft and the lathe tool that is installed on the tool rest, the anchor clamps that are used for fixing valve body are installed on the described rotating disk, described lathe tool by knife bar and the cutter head that radially is fixed on the knife bar constitute.
The head of cutter head is trapezoidal, and this trapezoidal bottom is the blade that is used to cut.
Described anchor clamps comprise the valve body carriage fixing with rotating disk, the screw rod that runs through valve body carriage sidewall and cooperate with valve body carriage sidewall thread, are positioned at the pressing plate of fixedlying connected with screw rod of valve body carriage.Valve body is placed in the valve body carriage, and the rotation by screw rod promotes pressing plate and compresses valve body.
After knife bar stretched into valve body together with cutter head, cutter head radially stretched between two sealing surfaces of valve body, and when the knife bar axially-movable, cutter head can contact and cut with two sealing surfaces respectively, to finish the processing of sealing surface.
The head of described cutter head and afterbody extend out from the two ends of radial direction through hole respectively, and bending formed bending part after afterbody extended radial direction through hole.Described bending part pastes the outer wall at knife bar.Bending part can prevent that cutter head from deviating from knife bar.
The head of described cutter head is trapezoidal, and this trapezoidal bottom is the blade that is used to cut.
Lathe of the present invention need not the valve body that overturns when two sealing surfaces of processing slide valve, only just can finish the processing of two sealing surfaces by the motion of lathe tool, has improved production efficiency.
Description of drawings
Fig. 1 is the partial structurtes schematic diagram of lathe of the present invention;
Fig. 2 is for being used for fixing the structural representation of the anchor clamps of valve body in the lathe of the present invention.
The specific embodiment
Referring to accompanying drawing, a kind of lathe that is used to process the slide valve sealing surface of the present invention, comprise and co-axially fixed rotating disk 1 of main shaft and the lathe tool that is installed on the tool rest, the anchor clamps that are used for fixing valve body are installed on the rotating disk 1, anchor clamps comprise the valve body carriage of fixing with rotating disk 12, the screw rod 6 that runs through valve body carriage 2 sidewalls and cooperate with valve body carriage 2 sidewall thread, are positioned at the pressing plate 5 of fixedlying connected with screw rod 6 of valve body carriage 2.Screw rod 6 other ends are provided with Spanner with aid 7.Valve body to be processed is placed in the valve body carriage 2, and the rotation by screw rod 6 promotes pressing plate 5 and compresses valve body.
Lathe tool is made of knife bar 3 and the cutter head 4 that is installed on the knife bar 3, and the head of cutter head 4 is trapezoidal, and this trapezoidal bottom is the blade that is used to cut.
Valve body rotation during use, after knife bar 3 stretched into valve body together with cutter head 4, the head of cutter head stretched between two sealing surfaces of valve body, and when knife bar moved, the head of cutter head can contact and cut with two sealing surfaces respectively, finishes the processing of two sealing surfaces of valve body.
Lathe of the present invention need not the valve body that overturns when two sealing surfaces of processing slide valve, only just can finish the processing of two sealing surfaces by the motion of lathe tool, has improved production efficiency.

Claims (3)
