Abstract

The technology provides a gate valve sealing surface rotating lathe clamping tool which can clamp a workpiece in one time, has high positioning accuracy and high production efficiency and is suitable for mass production. The gate valve sealing surface rotating lathe clamping tool comprises a transitional disc, an inclined plate, a fixed disc, a rotating disc, bolts, an eccentric positioning disc and pressing plate devices; the transitional disc is connected with a main shaft of a machine tool; the inclined plate is fixed on the transitional disc; the fixed disc contacts the inclined surface of the inclined plate and is fixed on the inclined plate; the rotating disc and the fixed disc share the same axis; the bolts for connecting the rotating disc with the fixed disc are symmetrically distributed around the axis of the fixed disc; the eccentric positioning disc deviates from the axis of the fixed disc and is connected with the rotating disc; and the pressing plate devices are arranged on rotating disc and used for clamping a gate valve and positioning through the eccentric positioning disc.

Description

Gate valve sealing surface rotating lathe clamping tool
Technical field
This technology relates to a kind of gate valve sealing surface rotating lathe clamping tool, belongs to metal cutting process field, is the technological equipment supporting with horizontal lathe.
Background technology
Gate valve sealing surface is symmetric wedge-shape anchor ring, a lot of to process of its processing, and conventional processing method has longer history and traditional, be take swash plate as rotary body, locate with single-ended flange and clamp, processing side inner sealing surface, after completing, then turn around to carry out other end processing; Its feature is that fixture is simple, but shortcoming is both sides inner sealing surface symmetry difficulty controls, and secondary clamping, machining accuracy is not high, and the clamping work auxiliary time is longer, and production efficiency is lower, inadaptable production in enormous quantities.
Summary of the invention
The object of this technology is to provide one only needs disposable clamping workpiece, and positioning precision is high, and production efficiency is high, is suitable for the gate valve sealing surface rotating lathe clamping tool produced in enormous quantities.
This gate valve sealing surface rotating lathe clamping tool, comprise the transition disc for being connected with machine tool chief axis, be fixed on a swash plate of transition disc, with the contact of incline plane of swash plate and the price fixing be fixed on swash plate, the rotating disk coaxial with price fixing, becomes axial symmetry to distribute with price fixing axis on the bolt that rotating disk is connected with price fixing; Rotating disk is connected with the eccentric positioning disk departing from price fixing axis; Rotating disk is also provided with the presser device of the gate valve clamping for being located by eccentric positioning disk.
Above-mentioned gate valve sealing surface rotating lathe clamping tool, rotating disk is rotatedly connected by deep groove ball bearing and price fixing.
Above-mentioned gate valve sealing surface rotating lathe clamping tool, rotating disk is arranged two and becomes axisymmetric pin-and-hole with the axis of price fixing, and price fixing is provided with pin that is dismountable, the arbitrary pin-and-hole stretched on rotating disk.
Above-mentioned gate valve sealing surface rotating lathe clamping tool, eccentric positioning disk is connected on rotating disk by disc.
The beneficial effect of this technology: during use, after rotating disk is spacing by pin relative to price fixing rotation, tightens the bolt that rotating disk is connected with price fixing, price fixing and rotating disk is locked.Transition disc is utilized to be connected with horizontal lathe spindle head.Then be correctly installed on eccentric positioning disk by gate valve body (work piece), the flange back side compressing gate valve body with presser device makes gate valve body fix.Open lathe, turning side gate valve body inner sealing surface; Parking after completing, the slightly loose bolt that rotating disk is connected with price fixing, extracts pin, relative to price fixing rotary turnplate 180 degree, inserts pin, again uses pin to after rotary disk limitation, tighten the bolt that rotating disk is connected with price fixing, carry out the processing of lock opposite side valve body inner sealing surface; Parking discharging after completing, a process-cycle completes.Therefore, use this gate valve sealing surface rotating lathe clamping tool, only need disposable clamping workpiece, positioning precision is high, and both sides inner sealing surface symmetry is good; And the work auxiliary time is few, production efficiency improves, and is suitable for and produces in enormous quantities.
Accompanying drawing explanation
Fig. 1 is gate valve sealing surface rotating lathe clamping tool schematic diagram.
Fig. 2 is the enlarged drawing of spacer pin, plug screw, spiral compression spring etc. in Fig. 1.
Detailed description of the invention
See Fig. 1,2, transition disc 01, connecting plate 02 are assembled into one with swash plate 03; Spacing key seat 06, spacer pin 07, plug screw 08, spiral compression spring 09 are assembled on price fixing 10, deep groove ball bearing (6218) 04, rotating disk 11, plain washer 12, hexagon nut with flange 13, T-slot bolt 14 are assembled on price fixing 10; Eccentric positioning disk 16 is installed on disc 15 be installed on together again on rotating disk 11; Three groups of presser devices that pressing plate 17, double threaded screw 18, hex nut 19, hex bolts 20 etc. form are installed on rotating disk 11.Swash plate 03 and price fixing 10 connected to form a complete vehicle clamper by hexagon socket cap head screw 05, be then connected with lathe main spindle nose by transition disc 01; Require that dial rotation steadily freely; Trial run and run is normal.Spacer pin under effect, extend into the pin-and-hole be positioned on rotating disk at spiral compression spring 09.Certainly, when applying axial force to spacer pin, spacer pin can be released pin-and-hole.
After rotating disk 11 rotary spacing, be wrenched hexagon nut with flange 13, price fixing 10 and rotating disk 11 are locked; Gate valve body (work piece) is correctly installed on eccentric positioning disk 16, with the pressing plate 17 supported flange back side, gate valve body is fixed; Open lathe, turning side gate valve body inner sealing surface; Parking after completing, slightly loose hexagon nut with flange 13, rotary turnplate 180 degree, after spacer pin 07 is spacing, is wrenched hexagon nut with flange 13, carries out the processing of opposite side gate valve body inner sealing surface; Parking discharging after completing, a process-cycle completes.
Productivity effect: gate valve sealing surface rotating lathe clamping tool bears radial load by 04 deep groove ball bearing, rotates steadily light, by three groups of T-slot bolts 14 lock rotating disk stablize firm; Disposable clamping workpiece, positioning precision is high, and two side inner sealing surface symmetries are good; And the work auxiliary time is few, production efficiency improves, and is suitable for and produces in enormous quantities.
