the utility model provides a two claw processing frocks of hydraulic pressure, includes the chuck, the chuck on be equipped with the clamping mechanism who is used for pressing from both sides tight pole head, clamping mechanism include two symmetric distribution's jack catch and install the briquetting of contacting with the pole head on the jack catch, the chuck on be equipped with the locating piece that is used for pole head assistance-localization real-time, the locating piece be located two jack catches between, the chuck in be equipped with the hydraulic system that can drive the jack catch.
The clamping jaw is characterized in that a rack used for the clamping jaw to move is arranged on the contact surface of the clamping jaw and the clamping chuck, and the rack is meshed and connected with a gear in the clamping chuck.
The upper end of the club head is in a flat bulb shape, the lower end of the club head is an axial section with two symmetrical planes, and the planes are parallel to the flat surface of the bulb at the upper end.
The pressing block is a semicircular metal block, and the inner diameter of the pressing block is slightly smaller than the outer diameter of the rod head shaft section.
The positioning block is internally provided with a cambered surface for positioning the club head, the width of the cambered surface is the same as the height size of the club head ball head, the positioning block is internally provided with an arc-shaped groove, the arc-shaped groove is positioned in the middle of the cambered surface, and the circle center of the arc-shaped groove is coincided with the circle center of the cambered surface.
The clamping jaw is internally provided with an arc-shaped groove used for installing a pressing block, and the diameter of the arc-shaped groove is the same as the outer diameter of the pressing block.
The circle center of the pressing block is positioned on the extension line of the positioning block.
The utility model has the advantages that: through designing a two claw processing frock and being used for the clamping that the pole head adds man-hour, solve the troublesome problem of clamping of pole head and can eliminate the eccentric calibration problem in the current clamping, can guarantee the processingquality of pole head simultaneously, reduce the time that is used for the clamping, improve production efficiency, and through the hydraulic drive clamping, it is simple quick, can further raise the efficiency.

Detailed Description
The present invention will be further explained with reference to the embodiments of the drawings.
A hydraulic two-jaw machining tool comprises a chuck 4, wherein a clamping mechanism used for clamping a rod head 1 is arranged on the chuck 4, the clamping mechanism comprises two jaws 3 which are symmetrically distributed and a pressing block 2 which is arranged on the jaws 3 and is in contact with the rod head 1, the pressing block 2 is fixed in an arc-shaped groove of the jaws 3, the bottom surface of the jaws 3 is in contact with the chuck 4, a rack used for moving the jaws 3 is arranged on the bottom surface of the jaws 3, the rack is in meshed connection with a gear in the chuck 4, the jaws 3 can move on the chuck 4 so as to loosen and clamp the rod head 1, the shaft section of the rod head 1 is clamped through the pressing block 2 during clamping, the rod head 1 is fixed in the tool, the inner diameter of the pressing block 2 is slightly smaller than the outer diameter of the shaft section of the rod head 1, so that the jaws 3 are in contact with the rod head 1 by at least four lines during clamping of the rod head 1, thereby guarantee that pole head 1 has sufficient clamp force, also let the radial positioning of pole head 1 obtain the assurance simultaneously, in addition, clamping mechanism's shape setting is for the flat structure of adaptation pole head 1 with the die joint, enable briquetting 2 furthest and pole head 1 surface contact, and produce the best fixed effect, just so can not appear like when using four-jaw chuck clamping because jack catch 3 appears in pole head 1's structure and pole head 1 contact is not comprehensive, and influence the clamping and stabilize and lead to the not good problem of processingquality, in addition, in this embodiment, two 3 accessible hydraulic system of jack catch drive simultaneously, and need not lock alone, and the clamping is convenient quick, reducible clamping time, improve production efficiency.
The positioning block 5 for assisting in positioning the club head 1 is arranged on the chuck 4, the positioning block 5 is positioned between the two clamping jaws 3, a cambered surface for positioning the club head 1 is arranged in the positioning block 5, the width of the cambered surface is the same as the height size of the club head 1 at the bulb position, the cambered surface of the positioning block 5 is a ball head arc structure for tightly fitting the club head 1, and the club head 1 cannot move left and right when being attached to the cambered surface due to the bending of the cambered surface, so that the positioning block 5 can play a role in fixing during clamping, in addition, an arc-shaped groove is arranged in the positioning block 5, is positioned in the middle of the cambered surface, the circle center of the arc-shaped groove is coincident with the circle center of the cambered surface, the circle center of the pressing block 2 is positioned on an extension line of the positioning block 5, so that the ball head surface of the club head 1, and the linear clamping of the rod head 1 can be ensured, and the eccentric condition caused by inaccurate limit can not occur, so that the calibration of clamping is improved, and the quality of products is ensured.
The problem that pole head 1 meets in the clamping just can be solved through above setting, reduces the clamping time, improves production efficiency, eliminates the processing off tracking problem among the prior art, guarantees product quality.
The above is only the preferred embodiment of the present invention, the present invention is not limited to the above embodiment, there may be local minor structural modification in the implementation process, if it is right that various modifications or variations of the present invention do not depart from the spirit and scope of the present invention, and belong to the claims and the equivalent technical scope of the present invention, then the present invention is also intended to include these modifications and variations.
