Description

The frock clamp that processing gate valve body is used
Technical field
The present invention relates to a kind of frock clamp, particularly relate to a kind of frock clamp that gate valve body is used of processing, belong to the technical field of processing equipment of gate valve body.
Background technology
The sealing effectiveness of valve is the important indicator of weighing valve mass, common valve is generally by lathe, its sealing surface to be carried out after turning processing, with soft sealing ring, seal again, the sealing effectiveness of this class valve mainly relies on sealing ring, long-term use easily leaked, service life is short, and reliability is not high.
The valve of existing employing hard sealing, reliability is higher, long service life.This class valve, after turning sealing surface, also will carry out grinding to sealing surface, makes valve sealing face reach higher flatness and roughness, thereby without using sealing ring also can reach good sealing effectiveness.In order to guarantee the sealing of valve body and spool, the sealing surface of hard seal gate valve valve body must be after processing guarantee its surperficial form and position tolerance and dimensional tolerance.
Yet existing processing method is generally by the method for Times cutter or milling machine processing, sealing surface to be processed, clamps before this valve body left side sealing surface is processed, then valve body dismounting is again clamped and rear right side sealing surface processed.Such processing method not only clamps more loaded down with trivial details difficulty; And repeatedly clamp operation, gradation processing sealing surface, the form and position tolerance of the sealing surface processing and dimensional tolerance are all difficult to obtain conforming assurance, effect is bad and change the process clamping also to lose time and can to cause operating gross efficiency low.In addition, flange position processing in valve body is needed again again to clamp processing, have equally the problem that working (machining) efficiency is low.
Summary of the invention
Main purpose of the present invention is, overcomes deficiency of the prior art, and a kind of frock clamp that gate valve body is used of processing is provided, and is specially adapted to the situation of highly-efficient processing gate valve body.
Technical problem to be solved by this invention is to provide the frock clamp that compact conformation, easy accessibility, processing gate valve body easy and simple to handle, safe and reliable, highly versatile are used, not only can realize and once clamp the multiple location processing that can complete valve body, can significantly improve working (machining) efficiency, and can reduce mismachining tolerance, guarantee processing uniformity, thereby guarantee crudy; Meanwhile, also can guarantee that the form and position tolerance of sealing surface and dimensional tolerance all coordinate with valve body, improve the sealing property of valve body product, and there is the value in industry.
In order to achieve the above object, the technical solution adopted in the present invention is:
Process the frock clamp that gate valve body is used, comprise for the rotary-tray of fixed valve body base with for pressing down and give the cover plate of valve body flange chucking power; Described rotary-tray is arranged on chassis, and described chassis is arranged in the fixed platform that corner is right angle, is provided with the fixedly stop pin of rotary-tray on described chassis; In described fixed platform, be provided with for supporting the column of cover plate, described cover plate is connected with column is detachable; Also comprise the conversion assembly being arranged on tray bottom and fixed platform right-angle side, described conversion assembly is for being transformed to plumbness from level along fixed platform right-angle side by chassis.
Wherein, described conversion assembly comprises a pair of fixed mount, single-revolution frame, a supporting plate and a pair of spring; Described a pair of fixed mount is parallel to be fixedly installed in the right angle perpendicular edge of fixed platform side by side, and described reversing frame is arranged between a pair of fixed mount and with fixed mount and is slidably matched; Described supporting plate and reversing frame are slidably matched; One end of described a pair of spring is connected with fixed mount, and the other end is connected with reversing frame; Described chassis is fixed on supporting plate.
Adopt technique scheme, gate valve body is carried out to the positions such as the left back flange of valve body or left and right sealing surface and add man-hour, can be by chassis in level; As added man-hour to the middle flange position of gate valve body, chassis to be transformed to plumbness from level along fixed platform right-angle side.During this time, the integral body of gate valve body clamps for once, when that is exactly level, valve base is fixed on rotary-tray, and flange in valve body is clamped with cover plate.
On chassis when level, first a side flange or the sealing surface of gate valve body are processed, after machining, by the rotary manipulation of rotary-tray, can process opposite side flange or the sealing surface of gate valve body, during all securing gate valve body need not be pulled down, do not need to convert process tool yet, and the rotary manipulation of rotary-tray is simple and efficient, therefore can significantly reduce mismachining tolerance, keep the uniformity of processing.This frock clamp also can be in the situation that not dismantling gate valve body, middle flange position to gate valve body processes, first by under the detachable cover plate of flange in clamping valve, then chassis is transformed to plumbness from level along fixed platform right-angle side, be now that process tool height on removable original facility is processed, process tool direction is identical during with the original processing left back flange of valve body or left and right sealing surface, realize and once clamp rear rapid processing multiple location, and crudy is guaranteed, error drops to minimum.
The present invention is further set to: on the axial direction of described a pair of fixed mount, offer symmetrical axial trough, described axial trough is made sliding action for the reversing frame axle being arranged on reversing frame sidewall; One end, described reversing frame two side is provided with the spring link for being connected with a pair of spring one end, and the described reversing frame two side other end is provided with symmetrical axis hole; In described axis hole, guide wheel shaft is installed, described guide wheel shaft supports supporting plate planar base; On the axial direction of described supporting plate dual-side, offer symmetrical chute, described chute is made sliding action for guide wheel shaft.
Technique scheme, described supporting plate completes slip by chute and guide wheel shaft, then supporting plate is along with reversing frame overturns to plumbness from level, then reversing frame completes slip by reversing frame axle and axial trough, realize reversing frame and fixed mount all in plumbness, supporting plate also drops to plumbness, completes the state transformation of chassis and upper valve body thereof, fast and easy processing.
The present invention is further set to: described reversing frame axle is vertically set on the centre of reversing frame sidewall.
