The special tool for the milling tank of the porous connector provided by the utility model has the advantages in that 1, the special tool has enough rigidity and can bear impact in a machining process; and 2, the special tool has simple indexing and has no indexing error.
Description
Technical field
The utility model relates to the manufacturing installation that presstressed reinforcing steel connects in a kind of prestressed concrete continuous structure, relates in particular to a kind of porous connector groove milling special tooling.
Background technology
In the pre-stress construction, porous connector is a kind of device that connects for prestressed concrete continuous structure presstressed reinforcing steel, and is multiplex in all kinds of Continuous Bridges.The architectural feature of porous connector is to hang Extruded anchoring tool at the circumference of workpiece, so peripheral uniform the corresponding groove that radially moves towards of porous connector.The width of groove is generally 16mm,, long be 30mm, and groove and workpiece spindle are to the gradient that has 5 °.Generally to the processing of this workpiece be on milling machine the installation universal dividing head to Workpiece clamping and calibration.But because this groove employing of the system of milling is three sword arc cutters, contact area is large, and the milling impulsive force is large; And the several fixed positions of dividing head Reusability, therefore accurate dividing head is easy to wear.Calibration also can occur sometimes shake mistake, cause workpiece to scrap.
The utility model content
The purpose of this utility model be for dividing head in the prior art wear and tear easily and shake wrong after the problem of products waste, a kind of porous connector groove milling special tooling is provided, reducing wearing and tearing, and improve machining accuracy.
The utility model is installed on the milling machine, the utility model comprises the bearing chamber that is fixed on the base plate, the radial thrust bearing of bearing indoor location, with the main shaft that is installed in the radial thrust bearing, main shaft one end is equipped with terminal pad, the other end is equipped with index dial, the circumferential locating slot of index dial is corresponding with the groove of workpiece circumference, the locating slot of index dial and the alignment pin of frock are engaged, be fixed with spanner by compressing spanner nut on the index dial, wherein have gradient between base plate and workpiece groove.
Radial thrust bearing quantity in the utility model is two, between terminal pad and workpiece Bolt to position is installed, and between base plate and milling machine table face bolt is installed.Gradient is five degree.
The utility model has the advantage of: 1. special tool is equipped with enough rigidity, the impact in the time of tolerating processing; 2. the special tooling calibration is simple, the calibration mistake can not occur.

Fig. 1 is the main apparent direction schematic diagram that confined state structure of the present utility model is removed dowel device;
Fig. 2 is that the utility model confined state is overlooked the direction cutaway view;
Fig. 3 is the left apparent direction schematic diagram of the assembling of this practical dowel device.
The specific embodiment
Such as Fig. 1,2, the utility model is installed on the milling machine, frock comprises the bearing chamber 3 that is fixed on the base plate 7, the radial thrust bearing of bearing chamber 3 interior installations, with the main shaft 2 that is installed in the radial thrust bearing, main shaft 2 one ends are equipped with terminal pad 8, the other end is equipped with index dial 4, index dial 4 circumferential locating slots are corresponding with the groove of workpiece circumference, the locating slot of index dial 4 and the alignment pin of frock 10 are engaged, be fixed with spanner 6 by compressing spanner nut 5 on the index dial 4, wherein have gradient between base plate 7 and workpiece groove.
Radial thrust bearing quantity in the utility model is two, between terminal pad 8 and workpiece Bolt to position is installed, and between base plate 7 and milling machine table face bolt is installed.Gradient is five degree.
Concrete scheme is: the frock body is a special bearing chamber 3, and bearing chamber 3 is fastened on the frock base plate 7, and base plate 7 one sides are made the gradient with corresponding 5 degree of workpiece groove, and the groove that mills out so just obtains corresponding gradient.Base plate 7 is fixed by bolts on the milling machine table face.
Two radial thrust bearings of bearing chamber 3 interior employings, the way moving of restriction main shaft 2 after adjusting.One end of main shaft 2 is connected with the conical surface and terminal pad 8, with the seam location, with bolt workpiece is fixed on the terminal pad 8 between terminal pad 8 and workpiece.
The other end of main shaft 2 is equipped with index dial 4, and index dial 4 circumferential locating slots are corresponding with the groove of workpiece circumference, and the locating slot of index dial 4 and the alignment pin of frock 10 are engaged.Under the spring pressure effect of alignment pin 10, alignment pin 10, index dial 4, main shaft 2, terminal pad 8, workpiece 1 namely with the porous connector that is processed to, are become one, stand the impulsive force of milling cutter.
Whenever after having milled a groove, pull the spanner 6 that compresses on the spanner nut 5, index dial 4 is moved a locating slot, can repeat the new groove of the system of milling.So repeat, can finish the processing of workpiece.
The elastic force of the spring 11 on the alignment pin 10 should can locking fixture, plays fixation, and spanner can be pulled smoothly.Therefore when installing, should consider the relation between the moment of milling cutter impulsive force, spring force and alignment pin and index dial.
The effect one that compresses spanner nut 5 be compress index dial make its fix, the 2nd, under the drive of spanner 6, rotate together with index dial, main shaft and workpiece.The direction that compresses the spanner nut rotation is the direction that compresses index dial, and is unlikely loosening when index dial 4 is rotated.
