Description
Technical Field
The utility model belongs to the technical field of screw rod drilling tool production, in particular to casing mills tooth frock under screw rod drilling tool.
Background
When a lower shell of a screw drill is machined, the lower shell needs to have a certain inclination (generally 1.5 degrees) according to machining requirements, but teeth on the end face of the lower shell need to be machined perpendicular to the end face, a common machine tool cannot machine such workpieces, a large-scale machining center needs to be used for corresponding machining, and how to machine such workpieces on the common machine tool is the direction of research.
SUMMERY OF THE UTILITY MODEL
The utility model provides a casing mills tooth frock under screw rod drilling tool can solve the problem that points out among the background art.
The utility model provides a casing mills tooth frock under screw rod drilling tool, includes angle cover and mills tooth frock cover, angle cover suit is fixed on the work piece, the angle is sheathe in and is had first suit hole, the axis in first suit hole with the angle difference has between the axis of angle cover, mill tooth frock suit and fix on the work piece, it has second suit hole to mill tooth frock sheathe in, the axis in second suit hole with it is poor to have the angle between the axis of milling tooth frock cover, and second suit hole with the inclination in first suit hole is unanimous.
Preferably, the angle sleeve is provided with a separation seam.
Preferably, a plurality of puller bolts are uniformly arranged in the circumferential direction of the gear milling tool sleeve.
Has the beneficial effects that: the utility model provides a casing mills tooth frock under screw rod drilling tool utilizes this cover frock, can realize the processing of common lathe to this type of work piece to need not use large-scale machining center, can accomplish processing.

Detailed Description
In the following, an embodiment of the present invention is described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.
Example 1:
as shown in fig. 1-2, a screw drill lower casing gear milling tool comprises an angle sleeve 1 and a gear milling tool sleeve 2, wherein the angle sleeve 1 is sleeved and fixed on a workpiece 3, a first sleeving hole 11 is formed in the angle sleeve 1, an angle difference is formed between the axis of the first sleeving hole 11 and the axis of the angle sleeve 1, the gear milling tool sleeve 2 is sleeved and fixed on the workpiece 3, a second sleeving hole 21 is formed in the gear milling tool sleeve 2, an angle difference is formed between the axis of the second sleeving hole 21 and the axis of the gear milling tool sleeve 2, and the inclination angle of the second sleeving hole 21 is identical (generally 1.5 degrees) to that of the first sleeving hole 11.
The angle sleeve 1 is provided with a gap 12, the gap 12 is arranged at the thickest part of the wall thickness of the angle sleeve 1, the angle sleeve 1 is sleeved on the workpiece 3, the angle sleeve 1 is fixed through a chuck on a lathe, and the angle sleeve 1 is tightened under the action of the gap 12 so as to clamp the workpiece 3.
Milling 2 circumferencial directions of tooth frock cover and evenly setting up a plurality of puller bolt 22, milling tooth frock cover 2 and having screw hole 23, puller bolt 22 wears to establish in screw hole 23, and milling tooth frock cover 2 suit is on work piece 3, and inboard screw in puller bolt 22 fixes work piece 3.
The utility model discloses a theory of operation: with particular reference to fig. 3-4, the angle sleeve 1 is sleeved on the workpiece 3, the angle sleeve 1 is fixed by a chuck on a lathe, the angle sleeve 1 is tightened under the action of the gap 12 to clamp the workpiece 3, one end of the workpiece 3 is milled by a cutter on the lathe to be flat and perpendicular to the cutter of the lathe, after the machining is completed, the angle sleeve 1 is taken down, the gear milling tool sleeve 2 is sleeved on the first end of the workpiece 3, a puller bolt 22 is screwed inwards to fix the workpiece 3, and the workpiece 3 is fixed because the inclination angle of the second sleeved hole 21 is consistent with that of the first sleeved hole 11, so that the end face machined by the angle sleeve 1 in the previous step is perpendicular to the gear milling cutter of the lathe, and teeth perpendicular to the end face can be milled.
The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any changes that can be considered by those skilled in the art shall fall within the protection scope of the present invention.
