Description
Technical field
The utility model belongs to C type union elbow technical field of processing equipment, relates to a kind of two-jaw(ed)chuck of the C of being used for type union elbow.
Background technology
Pipe joint is one of part the most frequently used in the hydraulic system, is widely used in the pipe-line system of various machineries, and also be simultaneously part commonly used in the aviation oil piping system, mainly play the effect of installation and connecting line system.Its specification is various in style, and C type union elbow is exactly wherein a kind of, but production lot is little; Seldom adopt advanced, special tooling efficiently, often use common processing method, lean on workman's technical merit to guarantee; Crudy is unstable, and precision is low, even causes a lot of waste products.
Summary of the invention
The purpose of the utility model provides a kind of two-jaw(ed)chuck of the C of being used for type union elbow, makes the convenient mounting and clamping of C type union elbow, can on engine lathe, accomplish the processing of C type union elbow.
The technical scheme that the utility model adopted is, is used for the two-jaw(ed)chuck of processing C-shaped bend pipe joint, comprises chuck and is arranged on two claws and the positioning reference seat on the chuck; Chuck is provided with centre bore, and two claws are distributed on the diameter of chuck L, and in the both sides of centre bore; Also be provided with gathering sill along its radius V on the chuck; The positioning reference seat comprises base plate, and the base plate bottom surface is provided with the guide pad corresponding with gathering sill, and guide pad is embedded in the gathering sill; Plate upper surface is provided with projection, is provided with pin-and-hole in the projection, and pin-and-hole is inclined to set, and is provided with alignment pin in the pin-and-hole, and the projection of the axis of alignment pin on chuck overlaps with the radius V of chuck.
Wherein, the radius V of chuck is vertical with diameter L.
Wherein, base plate is provided with mounting hole.
Wherein, chuck is provided with balancing weight.
The beneficial effect of the utility model is, can on engine lathe, process the end to C type union elbow, overcome the shortcoming that clamping in the existing processing is inconvenient, cannot say for sure to demonstrate,prove product quality; C type union elbow is adding man-hour, only need once adjust to the right place, and following process does not need centering, has improved working (machining) efficiency, has also guaranteed the quality of product simultaneously.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
Like Fig. 1, Fig. 2 and shown in Figure 3, the utility model provides a kind of two-jaw(ed)chuck that is used for the processing C-shaped bend pipe joint, comprises chuck 2 and is arranged on two claws 1 and positioning reference seat 5 on the chuck 2; Chuck 2 is provided with centre bore 9; Two claws 1 are distributed on the diameter L of chuck 2, and in the both sides of centre bore 9; Also be provided with gathering sill 7 along its radius V on the chuck 2.Like Fig. 4, Fig. 5 and shown in Figure 6, positioning reference seat 5 comprises base plate 10, and base plate 10 bottom surfaces are provided with the guide pad 8 corresponding with gathering sill 7, and guide pad 8 is embedded in 7 li of gathering sills; Base plate 10 upper surfaces are provided with projection 12; Be provided with pin-and-hole 13 in the projection 12; The centre of gyration line of the axis of pin-and-hole 13 and centre bore 9 is 45 ° of angles, is provided with alignment pin 6 in the pin-and-hole 13, and the projection of the axis of alignment pin 6 on chuck 2 overlaps with the radius V of chuck 2; The radius V of chuck 2 is vertical with diameter L.Base plate 10 is provided with mounting hole 11, and chuck 2 is provided with a plurality of screwed holes 3, passes mounting hole 11 and also lock with mounting hole 11 corresponding screwed holes 3 through screw positioning reference seat 5 is fixed on the chuck 2.Also be fixed with on the chuck 2 and guarantee chuck 2 dynamically balanced balancing weights 4.
During practical operation, the centre bore on the chuck 29 is installed on the main shaft of lathe, with the preliminary debugging that carries out frock through the C type bend pipe after the roughing.During debugging, unclamp the screw on positioning reference seat 5 mounting holes 11 earlier, and choose the alignment pin 6 that adapts with C type union elbow end locating hole, be installed on the pin-and-hole 13 of positioning reference seat 5, an end of C type union elbow is enclosed within on the alignment pin 6; Then; Let positioning reference seat 5 slide along the gathering sill 7 on the chuck 2; Guarantee on the centre of gyration line that is centered close to machine tool chief axis of C type union elbow other end end face that positioning reference seat 5 passes screw mounting hole 11 and also locks with mounting hole 11 corresponding screwed holes 3 after the position on the gathering sill 7 is confirmed; Positioning reference seat 5 is fixed on the chuck 2; Clamp the other end of C type union elbow then with two claws 1, the clamping position of inspection part has no change, and the processing C-shaped bend pipe joint is enclosed within the end on the alignment pin 6 behind the no change.After machining, unclamp two claws 1, take off C type union elbow; Proceed the processing of next C type union elbow, guarantee, need not to carry out again centering because C type union elbow right processing position is clamped by two claws 1; So working (machining) efficiency is high, steady quality.
The gathering sill 7 of positioning reference seat 5 on the chuck 2 slides, and is on the centre of gyration line that is centered close to machine tool chief axis for the other end end face of the C type union elbow of regulating different sizes; And can select a plurality of specification alignment pins for use,, enlarge the scope of application of the utility model, improve economic benefit to adapt to the C type union elbow of different size and size.
