Description
Technical field
The utility model relates to valve industry valve gap lathe machined frock clamp field used, is the valve gap frock of a kind of clamped one time multistation processing specifically.
Background technology
For gate valve, need when traditional gate valve cover carries out turnery processing to carry out two procedures, i.e. operation one: turning end flanges cylindrical, sealing surface boss and filler endoporus, operation two: turning inner hole of bearing seat, plane.Above-mentioned turning needs to carry out twice installation, and there is bearing saddle bore and stuffing hole axiality problem bigger than normal, when causing valve to assemble, valve rod degree of bias great Yi pulls valve rod and affects valve seal performance etc.
There is the drawback that working (machining) efficiency is low, machining accuracy is poor in tradition frock, because the axiality of gate valve cover to stuffing hole and bearing saddle bore requires very high, its machining accuracy affects the service life of valve rod and the serviceability of valve entirety, so the axiality of stuffing hole and bearing saddle bore is the critical process that valve gap is processed, also be the link that in the processing of existing gate valve cover, difficulty is maximum, utilize traditional frock machining accuracy not easily to ensure.Therefore are objects of the utility model research for the problems referred to above.
Utility model content
The purpose of this utility model is the valve gap frock providing a kind of clamped one time multistation to process, the valve gap frock of this clamped one time multistation processing can realize the processing of valve gap clamped one time multistation, multiple clamping is avoided to install, solve multiple clamping to need to reorientate the problem causing machining accuracy difference, substantially increase machining accuracy, reduce valve gap machine tooling operation, improve working (machining) efficiency, saved processing cost.
The technical solution of the utility model is: a kind of valve gap frock of clamped one time multistation processing, comprise the collet of a right angle rack and a U-shape, described right angle rack is provided with the collet locating slot for locating collet, collet two support arm is provided with the valve gap locating slot of the semi-circular shape for locating valve gap, two valve gap locating slots are added is provided with a valve gap, one locating shaft is through valve gap, collet and right angle rack, briquetting with U-lag is tightly suppressed valve gap by nut by locating shaft upper end, locating shaft lower end coupling nut, the locating shaft be positioned on collet is provided with a clamping screw and is locked on locating slot by collet, positioning shaft sleeve between collet and right angle rack has a Compress Spring.
In order to improve positioning precision, be positioned at the spring groove that collet lower surface and right angle rack upper surface respectively get deeply stuck in an accommodating Compress Spring.
For the ease of being arranged on lathe, being positioned at right angle rack and being provided with multiple bolt hole for being arranged on lathe.
The utility model has the advantage of: one is that the valve gap frock that this clamped one time multistation is processed can realize the processing of valve gap clamped one time multistation, multiple clamping is avoided to install, solve multiple clamping to need to reorientate the problem causing machining accuracy difference, substantially increase machining accuracy; Two is reduce valve gap machine tooling operation, improves working (machining) efficiency, has saved processing cost; Three is utilize right angle rack and collet to entrust valve gap, collet is connected with locating shaft, and such right angle rack is fixed on after on lathe, and collet entrusts valve gap can carry out 360 ° of rotations, right angle rack and collet have collet locating slot, can ensure to process the coaxial of valve gap axis and lathe spindle.

Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below, but the utility model is not limited to this.
With reference to legend 1-4, a kind of valve gap frock of clamped one time multistation processing, comprise the collet 2 of a right angle rack 1 and a U-shape, described right angle rack 1 is provided with the collet locating slot 3 for locating collet 2, collet 2 liang of support arms are provided with the valve gap locating slot 5 of the semi-circular shape for locating valve gap 4, two valve gap locating slots 5 are added is provided with a valve gap 4, one locating shaft 6 is through valve gap 4, collet 2 and right angle rack 1, briquetting 7 with U-lag is tightly suppressed valve gap 4 by nut by locating shaft 6 upper end, locating shaft 6 lower end coupling nut, the locating shaft 6 be positioned on collet 2 is provided with a clamping screw 8, collet 2 is locked on locating slot, locating shaft 6 between collet 2 and right angle rack 1 overlaps and has a Compress Spring 9.The valve gap frock of this clamped one time multistation processing can realize the processing of valve gap clamped one time multistation, multiple clamping is avoided to install, solve multiple clamping to need to reorientate the problem causing machining accuracy difference, substantially increase machining accuracy, reduce valve gap machine tooling operation, improve working (machining) efficiency, save processing cost.
Right angle rack 1 and collet 2 pairs of valve gaps 4 are utilized to entrust, collet 2 is connected with locating shaft 6, such right angle rack 1 is fixed on after on lathe, collet entrusts valve gap 4 can carry out 360 ° of rotations, right angle rack 1 and collet 2 have collet locating slot 3, can ensure to process the coaxial of valve gap axis and lathe spindle.
In order to improve positioning precision, be positioned at the spring groove that collet 2 lower surface and right angle rack 1 upper surface respectively get deeply stuck in an accommodating Compress Spring 9.
For the ease of being arranged on lathe, being positioned at right angle rack 1 and being provided with multiple bolt hole for being arranged on lathe.
Work operation instruction of the present utility model: right angle rack is fixedly connected with the main shaft of lathe by soket head cap screw, collet connects locating shaft and is inserted in spring together through right angle rack hole locking with hex nut, valve gap is installed in the valve gap locating slot of collet and compresses with briquetting and lock with hex nut, unclamping nut below right angle rack relies on Compress Spring to be upspring by collet, rotary bottom support is to the first station (turning end face of flange), then collet is put into push down in collet locating slot and with briquetting and then use nut check, now can turnery processing flange excircle and end face and seal boss.
The nut of locking positioning axle below right angle rack is unclamped, collet is upspring by Compress Spring, collet and collet locating slot depart from, collet also coordinates with collet locating slot and uses the nut check of right angle rack lower end by rotary bottom support 180 ° again, can realize the turnery processing (turning bearing saddle bore end face and endoporus) of the second station.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
