Description
Technical field
The utility model relate to a kind of fixture, has been specifically related to a kind of positioning tool for ball for ball valve processing valve rod connecting hole.
Background technology
Ball valve, is defined as in standard GB/T21465-2008 " valve term ": opening and closing element (spheroid) is driven by valve rod, and around the valve that ball valve axis rotates.Also can be used for the regulating and control of fluid, wherein firmly seal V-type ball valve, between its V-type ball core and metal seat valve of pile-up welding hard alloy, there is very strong shearing force, be specially adapted to the medium of fibre-bearing, a small solid material etc.; And multi-pass ball valve not only can the interflow of control medium, shunting and the switching that flows to flexibly on pipeline, also can close arbitrary passage simultaneously and two other passage is connected.
Ball for ball valve is the opening and closing element of ball valve, before being arranged in a body, need to process the connecting hole connecting valve rod thereon, but due to the characteristic of automobile-used ball for ball valve itself, cause fixing it in machine-shaping process and clamping certain difficulty, shaping ball for ball valve often because cause spheroid aperture inaccuracy in process displacement, and then affect the result of use of ball valve; Chinese patent patent No. CN201420764941.8, disclose a kind of automobile-used ball for ball valve periphery frock clamp and sanding apparatus, be made up of expansion post, hydraulic mandril, motor, lathe tool seat and lathe tool, described expansion post is mutually inlayed by least two pieces of cylinders and is formed, and this expansion post is arranged on the end of hydraulic mandril, under the effect of hydraulic pressure, hydraulic mandril can be pushed ahead and be forced the external diameter of expansion post to expand gradually until can be meshed with the internal diameter of ball valve body; Described lathe tool seat is provided with at least one piece of lathe tool, and the lathe tool arc lathe tool that to be radius consistent with the external diameter of ball valve body; Although this frock, can fixed by ball for ball valve, but its complicated structure, operate more difficult, hydraulic mandril pressure is excessive, is also easily damaged by pressure by expansion post, makes its permanent deformation, cannot continue to use.
Utility model content
The purpose of this utility model is the positioning tool for ball for ball valve processing valve rod connecting hole providing a kind of structure simple, easy to operate.
The technical solution of the utility model is: for the positioning tool of ball for ball valve processing valve rod connecting hole, comprise lower platen and top board, described lower platen is provided with the cone shaped countersink for placing ball for ball valve, gripper shoe is provided with in cone shaped countersink, pressing down between wooden partition in gripper shoe and cone shaped countersink is provided with elastic component, and top board is for being connected to lower platen with removably connecting through the spheroid hole on ball for ball valve.
The beneficial effects of the utility model are: lower platen serves the effect supporting whole spheroid; Be placed on the cone shaped countersink of lower platen by ball for ball valve to be processed, cone shaped countersink is the opening of an inverted round stage, and its countersink is also the arc coordinated with spheroid, is placed on cone shaped countersink so spheroid can be stable; After spheroid puts into cone shaped countersink, spheroid lower surface can contact with the gripper shoe be arranged in cone shaped countersink, pressing down between wooden partition in gripper shoe and cone shaped countersink is provided with elastic component, gripper shoe can be pressed by spheroid and move to the direction that presses down wooden partition in cone shaped countersink, now elastic component is compressed, and elastic component is to the thrust in the oriented direction near spheroid of gripper shoe.
Then top board is fetched, and by top board through ball for ball valve spheroid hole be connected on lower platen with removably connecting, the mode of removably connecting can for being threaded, clamping or by using connecting rod both to be connected to top board and lower platen perforate; By with upper type, top board is connected the thrust produced with lower platen, ball for ball valve is fixed on lower platen, spheroid will press gripper shoe further towards the direction motion pressing down wooden partition in cone shaped countersink, right being further compressed of elastic component, the thrust of gripper shoe to spheroid can be made to increase further, the thrust that top board is connected with lower platen and the thrust towards close top board direction that gripper shoe applies spheroid, what spheroid top board can be made to offset is tighter, thus forms stable clamping structure.
Compared with prior art, spheroid is fixed primarily of top board and lower platen by this frock, and the clamping force connected by both, makes spheroid more stable, and its structure is very simple, and operation is also very easy to, practical, is suitable for promoting the use of.
Further: top board and lower platen removably connect mode for being threaded.Being threaded is a kind of to be widely usedly dismountablely fixedly connected with, have structure simple, connect the advantages such as reliable, mounting or dismounting are convenient; Be threaded connection, can regulate the clamping force between top board and lower platen as required, what spheroid can be made to be fixed is more stable.
Further: top board and lower platen are linked together by detachable connecting device, detachable connecting device comprises and is connected to the symmetrical projection of on lower platen side two of top board, two projections are located at the both sides of top board, two projections all have the first through hole, lower platen has the groove that two coordinate projection, in two grooves, both sides press down two the second through holes wooden partition all having cooperation first through hole, also comprise two fixed bars, two fixed bars are all in the first through hole of inserting cooperation and the second through hole.After spheroid is placed on lower platen, by top board through spheroid hole, two projections are inserted in the groove of cooperation, re-use in the first through hole and the second through hole that fixed bar is inserted into cooperation, form detent mechanism top board being fixed on lower platen; After top board is fixed, top board coordinates with gripper shoe and forms clamp system.
Further: cone shaped countersink is provided with rubber washer near top board side.When spheroid is clamped, spherome surface can with the lower platen surface contact of cone shaped countersink, lower platen and spheroid are rigid contact, lower platen easily by spherome surface scratch, there is indenture; Adding of rubber washer, lower platen can be made directly not contact with spheroid, and rubber mass is soft, easily produces elastic deformation, spherome surface can not be scratched.
