Abstract
The invention relates to a machining clamping tool for valve bodies of stop valves. The machining clamping tool mainly comprises a fixture, clamping jaws, screws, guide plates, a stop block and set screws. The two clamping jaws are arranged at the upper end of the fixture, two pairs of set screws are symmetrically arranged in the middles of the two clamping jaws, the two screws are respectively arranged at the bottoms of the two clamping jaws, turning directions of threads of the two screws are opposite to each other, a cavity is formed between the two clamping jaws after the two clamping jaws approach each other, a valve body can extend into the cavity, and the stop block is mounted at the bottom of the U-shaped cavity and is fixed by the aid of a hexagon socket screw mounted on the fixture; the guide plates are arranged on two sides of the bottom of each clamping jaw, cling to two ends of the clamping jaw and are fixed by the aid of bolts. The machining clamping tool has the advantages that the valve body is clamped by the clamping jaws at two ends of the machining clamping tool when required to be clamped, is fixed by the aid of the set screws simultaneously and can be assuredly fixedly clamped, and accordingly the labor intensity can be reduced.
Description
Technical field
The present invention relates to a kind of stop valve body processing clamping tool, specifically a kind of can be good at the device of the valve body clamping of stop valve.
Background technology
Stop valve claims again pipe valve valve, belongs to forced seal formula valve, so when valve closing, must exert pressure to flap, with forced seal face, does not leak.When medium enters valve by flap below, the required resistance overcoming of operating physical force, is the frictional force and the thrust being produced by the pressure of medium of valve rod and filler, and the power that the force rate of closing valve is opened valve is large, so it is large that the diameter of valve rod is wanted, otherwise can there is the fault of valve rod bending.By connected mode, be divided into three kinds: flange connection, screwed connection, be welded to connect.From self-packing valve occurs, the MEDIA FLOW of stop valve enters valve pocket to just changing by flap top, and at this moment, under pressure medium effect, the power of closing valve is little, and it is large to open the power of valve, and the diameter of valve rod can correspondingly reduce.Meanwhile, under medium effect, the valve of this form is also tighter.China's valve " three changes are given " is regulation once, and the flow direction of stop valve, adopts from top to bottom without exception, and this valve is wanted level installation.
At present, in the prior art, in the process for stop valve processing, in the time the valve body of stop valve need to being clamped, existing way is manually to clamp.Adopt such method, hand labor intensity is large, and is not easy to operation.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of stop valve that can be good at the valve body of stop valve to clamp and processes clamping tool.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of stop valve processing clamping tool, and its innovative point is: mainly comprise clamp body, jaw, screw rod, guide plate, limited block and holding screw;
The upper end of described clamp body is provided with jaw, two altogether of described jaws, medium position symmetry at two jaws is provided with a pair of holding screw, described holding screw from outside to inside level stretches in jaw, and the head of holding screw stretches out the inwall of jaw, in the bottom of two jaws, be provided with a screw rod, described screw rod from outside to inside level stretches in jaw, described two screw flight rotation directions arrange on the contrary, simultaneously on jaw with the helicitic texture matching with screw rod;
After described two jaws are close, between two jaws, formed one and held the cavity that valve body stretches into, the cross section of the described cavity shape that takes the shape of the letter U, is provided with limited block in the bottom of U-shaped cavity, described limited block is fixed by being arranged on the hexagon socket head cap screw of clamp body, to limit screw axial play; ;
The both sides of the bottom of described jaw are provided with guide plate, and described guide plate is close to the two ends of jaw, and are fixed by bolt, and limited block is led.
The invention has the advantages that: when valve body is clamped, utilize the jaw at two ends to clamp valve body, use holding screw fixed valve body simultaneously, guaranteed being fixedly clamped of valve body, reduced hand labor intensity.

The specific embodiment
Schematic diagram is as shown in Figures 1 and 2 known, and stop valve body processing clamping tool of the present invention mainly comprises clamp body 1, jaw 7, screw rod 2, guide plate 10, limited block 9 and holding screw 3.
In the upper end of clamp body 1, be provided with jaw 7, two altogether of jaws 7, medium position symmetry at two jaws 7 is provided with a pair of holding screw 3, holding screw 3 from outside to inside level stretches in jaw 7, and the head of holding screw 3 stretches out the inwall of jaw 7, in the bottom of two jaws 7, be provided with a screw rod 2, screw rod 2 from outside to inside level stretches in jaw 7, the thread rotary orientation of two screw rods 2 arranges on the contrary, simultaneously on jaw 7 with the helicitic texture matching with screw rod 2.
After two jaws 7 are close, between two jaws 7, formed one and held the cavity that valve body 11 stretches into, the cross section of this cavity shape that takes the shape of the letter U, is provided with limited block 9 in the bottom of U-shaped cavity, limited block 9 is fixed by being arranged on the hexagon socket head cap screw 8 of clamp body, to limit screw axial play.
Both sides in the bottom of jaw 7 are provided with guide plate 10, and guide plate 10 is close to the two ends of jaw 7, and is fixed by bolt 5, to limited block 9 guiding, at guide plate 10, are evenly provided with several taper bolts 6, positioning guiding plate.
The schematic diagram of Fig. 3, Fig. 4 is depicted as and utilizes this clamping tool stop valve body to be processed to the schematic diagram clamping.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
