Description
Technical field
The utility model relates to a kind of clamp for machining of tee pipe fitting joint.
Background technology
In the ordinary course of things, be nothing but by clamping, the correction respectively of three of joint terminations to the processing technology of tee pipe fitting joint, then carry out each turning.
This technique also exists a fatal weakness when being the other end needing each time to convert working joint, and correct always, not only time-consuming but also require great effort, work efficiency is quite low.
Utility model content
Technical problem to be solved in the utility model is when providing a kind of other end at each conversion working joint for the above-mentioned state of the art, and need not correct just can the clamp for machining of the direct tee pipe fitting joint of feed turning.
For achieving the above object, the technical scheme that provides of the utility model is as follows:
A clamp for machining for tee pipe fitting joint, includes support, two index tables, positioner and hold down gags,
Described support is one piece of bent plate with the axis of cone, and the described axis of cone is No. 6, Morse's taper, and described support offers at least two taper holes;
Described index table is fixed with vertex of a cone axle, described vertex of a cone axle and above-mentioned taper hole suitable and can be plugged in described taper hole, described index table also offers two V-shaped grooves and locating hole;
Described positioner is removably fixed in the locating hole of described index table;
Tee pipe fitting joint is fixed with in above-mentioned V-shaped groove, described hold down gag comprises parallels, nut, screw rod and pressing plate, described parallels abuts in the surface of described index table, and described pressing plate is pressed together on described parallels, and is fixed on described index table by described nut and screw rod.
As the improvement of the clamp for machining of tee pipe fitting joint above-mentioned in the utility model, described positioner includes alignment pin, stifled platform and spring, described spring and described alignment pin are all fixed on described stifled platform, and one end of alignment pin is connected on described spring, described stifled platform is removably fixed in the locating hole of described index table.
As further improvement of the utility model, in described locating hole, offer internal thread, described stifled platform is connected in described locating hole by screw flight.
Improve as another kind of the present utility model, described locating hole is pin-and-hole, and described stifled platform is fixed by a pin in described locating hole.
Compared with prior art, the utility model has the advantage of: do not need calibration of workpieces just can divide three ports of three above-mentioned joints of direct feed turning, both the ingenious fine and close weakness overcoming traditional handicraft and exist, in turn ensure that the rapid processing of workpiece, improve operating efficiency.

Detailed description of the invention
Be described in further detail below in conjunction with the clamp for machining of accompanying drawing embodiment to tee pipe fitting joint of the present utility model.
As shown in Figure 1, the present embodiment is a kind of clamp for machining of tee pipe fitting joint, include support 1, two index tables 2, positioner 3 and hold down gags 4, described support is one piece of bent plate with the axis of cone 11, the described axis of cone is that (cone bevel angle is 1 ° 29 ' 36 ") to No. 6, Morse's taper; this axis of cone can match with the spindle hole of numerically controlled lathe, has self-locking action.Above-mentioned support is formed with the datum level 12 of a level, the distance of described seat surface 12 to lathe spindle axial line is 28 ± 0.05mm.
Described support offers two taper holes 13, aforesaid index table 2 is fixed with vertex of a cone axle 21, this vertex of a cone axle 21 can be located in taper hole 13, then be fixed by locking nut 5, above-mentioned locking nut 5 is screwed into by the opposite side of taper hole, when unclamping locking nut 5, this index table 2 can do the rotation of 360 degree relative to the datum level 12 of support.
Described index table 2 also offers two V-shaped grooves 22 and locating hole 23, workpiece 6(tee pipe fitting joint to be processed) be just fixed in above-mentioned V-shaped groove 22, and by hold down gag 4, above-mentioned workpiece is compressed.
Described hold down gag 4 comprises parallels 41, nut 42, screw rod 43 and pressing plate 44, described parallels abuts in the surface of described index table, described pressing plate 44 to be pressed together on described parallels and by above-mentioned Work-sheet pressing in V-shaped groove 22, by described nut 42 and screw rod 43, pressing plate is locked on described index table subsequently, here, the height of parallels is determined according to the situation of workpiece, makes the height at its top consistent with the height of workpiece top.
In order to not need directly to adjust through correcting process when switching the processing termination of workpiece, positioner 3 is also provided with in the clamp for machining of the present embodiment, described positioner includes alignment pin 31, stifled platform 32 and spring 33, described spring 33 is all fixed on described stifled platform with described alignment pin 31, and one end of alignment pin 31 is connected on described spring 33, and described stifled platform is threaded connection or the mode of pin joint is removably fixed in the locating hole of described index table.After the V-type index table 90 ° or 180 ° of one end rotational support workpiece processing joint, in positioner 3, the cone end of alignment pin 31 will due to the thrust of spring, insert in the locating hole on index table 2, guarantee the accurate calibration location of workpiece, thus carry out feed turning.
The concrete using method of clamp for machining of the present embodiment is as follows: first the axis of cone of fixture support 1 loaded in the spindle hole of numerically controlled lathe, linked together by the self-locking action of Morse's taper and lathe spindle, unclamp nut 42, raise pressing plate 44, workpiece is loaded in vertical V-type groove 22, at fastening nut 42, thus by Work-sheet pressing, start lathe, just can the one end in feed turning threeway street corner.When processing this one end and needing the conversion processing other end, unclamp nut 42, rotary index table to 90 ° or 180 °, both directly feed can distinguish the other two ends of turning three-way connection.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
