Abstract
The utility model relates to a clamping fixture for machining a valve body of a stop valve. The clamping fixture mainly comprises a clamp body, clamping jaws, screw rods, guide plates, a limiting block and fastening screws. The two clamping jaws are arranged at the upper end of the clamp body, a pair of fastening screws are symmetrically arranged at the middle positions of the two clamping jaws, the bottoms of the two clamping jaws are respectively provided with one screw rod, and the screw directions of threads of the two screw rods are arranged oppositely. After the two clamping jaws are close, a cavity which allows the valve body to extend in is formed between the two clamping jaws, the limiting block is mounted at the bottom of the U-shaped cavity, and the limiting block is fixed through a hexagon socket screw mounted in the clamp body. The guide plates are arranged on the two sides of the bottom ends of the clamping jaws, and the guide plates are closely attached to the two ends of the clamping jaws and are fixed through bolts. The clamping fixture for machining the valve body of the stop valve has the advantages that when the valve body is clamped, the clamping jaws at the two ends are used for clamping the valve body, meanwhile, the fastening screws are used for fixing the valve body, clamping and fixing of the valve body are guaranteed, and the labor intensity of workers is lowered.
Description
Technical field
The utility model 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 in the time of valve closing, must exert pressure to flap, does not leak with forced seal face.In the time that medium enters valve by flap below, the required resistance overcoming of operating physical force, is the frictional force of valve rod and filler and the thrust being produced by the pressure of medium, 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.Be divided into three kinds by connected mode: 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.Once regulation of China's valve " three changes are given ", 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.
Utility model content
The technical problems to be solved in the utility model 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, the technical solution of the utility model 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, be provided with a screw rod in the bottom of two jaws, 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 the hexagon socket head cap screw that is arranged on 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 utility model has the advantage of: in the time that 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 utility model mainly comprises clamp body 1, jaw 7, screw rod 2, guide plate 10, limited block 9 and holding screw 3.
Be provided with jaw 7 in the upper end of clamp body 1, two altogether of jaws 7, be provided with a pair of holding screw 3 in the medium position symmetry of two jaws 7, 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, be provided with a screw rod 2 in the bottom of two jaws 7, 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 the hexagon socket head cap screw 8 that is arranged on clamp body, to limit screw axial play.
Be provided with guide plate 10 in the both sides of the bottom of jaw 7, guide plate 10 is close to the two ends of jaw 7, and is fixed by bolt 5, and limited block 9 is led, and is evenly provided with several taper bolts 6, positioning guiding plate at guide plate 10.
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 utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
