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.
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 because the hydraulic mandril speed of service is comparatively slow, extruding fixed efficiency is low.
Utility model content
The purpose of this utility model is that providing a kind of extrudes the high positioning tool for ball for ball valve processing of fixed efficiency.
The technical solution of the utility model is: a kind of positioning tool for ball for ball valve processing, comprise mobile jib, the middle part of mobile jib is rotatably connected to expander, be provided with left hand thread on the left of described mobile jib, the right side of mobile jib is provided with right-handed thread, and the mobile jib of the both sides of expander is connected with nut, the both sides of expander are equipped with the sleeve of restriction nut rotation, jacket casing is located on nut, and one end of mobile jib is removably connected with connecting rod, and the other end of connecting rod is connected with motor.
The beneficial effects of the utility model are: starter motor, driven by motor connecting rod rotates, connecting rod drives mobile jib to rotate, mobile jib rotates, expander is motionless, and then sleeve can be made motionless, sleeve is motionless, two nuts can be rotated by two sleeve restrictions, be located at left-handed threaded portion nut on mobile jib the direction near expander to be moved, be located at dextrorotation threaded portion nut on mobile jib also the direction near expander to be moved, thus two nuts move to relatively close direction, produce clamping force, and step up expander, expander is stressed, start dilatancy, two nuts move to till ball for ball valve fixes by expander always, this frock is by Electric Machine Control, and its speed is higher than the speed of hydraulic mandril, and simultaneously this frock pushes up compression swelling body by two nuts, promotes expander speed of expansion further, thus improves the fixing efficiency of extruding.
After ball for ball valve is fixed by expander, disable motor, mobile jib is disassembled from connecting rod, mobile jib connect the mode of connecting rod can be threaded, clamping or key connect, frock with ball for ball valve is transferred on ball grinding device, uses three to grab one end that chuck steps up mobile jib, and use hydraulic mandril to withstand the other end of mobile jib, mobile jib is positioned on processing unit (plant), and then starts to process ball for ball valve.
Further: the mode of removably connecting is that key connects.Key connects, and when mobile jib has fixed ball for ball valve, directly can be chosen down from connecting rod by mobile jib, not need too much screwing or dismantling, improve the operating efficiency of whole work.
Further: connecting rod is connected with the first gear away from one end of mobile jib, and the first gears meshing has the second gear, the size of the second gear is less than the size of the first gear, and motor is connected on the second gear.The angular speed of the first gear is less than the angular speed of the second gear, because motor rotation speed is too fast, this is arranged, and can slow down the speed that motor exports.
Further: expander is cylindrical shape, and on columnar expander, circumference is evenly equipped with trachoma.Trachoma refers to the through hole that irregular diameter is very little, and generally use gas welding to process, the setting of trachoma, can strengthen the inflatable elastomeric of expander, makes expander be easy to dilatancy.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of positioning tool embodiment for ball for ball valve processing of the utility model;
Fig. 2 is the part left view of mobile jib in Fig. 1.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: mobile jib 1, hex nut 2, Hexagonal jacket 3, expander 4, support 5, connecting rod 6, first gear 7, second gear 8, motor 9.
Embodiment is substantially as shown in Figures 1 and 2: a kind of positioning tool for ball for ball valve processing, comprise mobile jib 1, mobile jib is rotatably connected to support 51 time, the middle part of mobile jib 1 is rotatably connected to expander 4, left hand thread is provided with on the left of described mobile jib 1, the right side of mobile jib 1 is provided with right-handed thread, the mobile jib 1 of the both sides of expander 4 is connected with hex nut 2, the both sides of expander 4 are equipped with the Hexagonal jacket 3 of restriction hex nut 2 rotation, Hexagonal jacket 3 is sheathed on hex nut 2, one end flat key of mobile jib 1 is connected with connecting rod 6, the other end of connecting rod 6 is connected with the first gear 7, first gear 7 is engaged with the second gear 8, the size of the second gear 8 is less than the size of the first gear 7, motor 9 is connected on the second gear 8.
Starter motor 9, motor 9 drives the second gear 8 to rotate, second gear 8 drives the first gear 7 to rotate, first gear 7 drivening rod 6 rotates, and connecting rod 6 drives mobile jib 1 to rotate, and mobile jib 1 rotates on support 5, expander 4 is motionless, expander 4 can use the columnar steel plate of one-body molded one-tenth to be made, and columnar steel plate uses gas welding, welds the trachoma of rule, expander 4 is fixed, and then Hexagonal jacket 3 can be made motionless, Hexagonal jacket 3 is motionless, two hex nuts 2 can be limited rotation by two Hexagonal jackets 3, be located at left-handed threaded portion hex nut 2 on mobile jib 1 direction near expander 4 to be moved, be located at dextrorotation threaded portion hex nut 2 on mobile jib 1 also the direction near expander 4 to be moved, thus two hex nuts 2 move to relatively close direction, produce clamping force, and step up expander 4, expander 4 is stressed, start dilatancy, two hex nuts 2 move to till ball for ball valve fixes by expander 4 always.
After ball for ball valve is fixed by expander 4, disable motor 9, mobile jib 1 is disassembled from the flat key connecting rod 6, frock with ball for ball valve is transferred on ball grinding device, three are used to grab one end that chuck steps up mobile jib 1, and use hydraulic mandril to withstand the other end of mobile jib 1, mobile jib 1 is positioned on processing unit (plant), and then starts to process ball for ball valve.
