The embodiment of the present invention.
Referring to attached drawing 1-2, the utility model proposes a kind of for processing the tooling of the nut of ball-screw, comprising: the
One the first clamping device of chuck 1(), second the second clamping device of chuck 2() and holding unit 5.Wherein, the first chuck 1 and second
Chuck 2 is rotatable to be fixed on lathe, and coaxial positioned opposite, is rotated by driving mechanism, such as motor driven.Wherein first
The end face of chuck 1 is equipped with pillar 12 and is additionally provided with the first top on the end face of the first chuck 1 along the central axis of the first chuck 1
Point 11；Along the central axis of the second chuck 2, second top 21 is equipped on the end face of the second chuck 2；Described first top 11
(the first chuck) and second top the second chuck of 21() it is coaxial positioned opposite.
Wherein, holding unit 5 includes cylindrical section 51, clamping part 52, connecting rod 53 and clamp device 54.Wherein, cylindrical section 51
Edge is axially arranged with through-hole 511；Circumferentially along cylindrical section 51, in the present embodiment, clamp device 54 is screw to clamp device 54,
Quantity is 2, however is also possible to other and fixes device, such as rivet etc., and quantity can be 1 or 3-5；Clamping part 52 includes
The symmetry axis of round plate 521 and symmetrical fan-shaped protrusion 522, the symmetrical fan-shaped protrusion 522 is round plate 521
Diametrical direction, projected direction be with round plate 521 towards the contrary direction of cylindrical section 51, it is described symmetrical
Fan-shaped protrusion 522 forms a groove 55 on round plate 521.The connecting rod 53 is fixed on cylindrical section 51 by the way of welding
Cylindrical surface on.
Wherein, the diameter of round plate 521 is greater than the diameter of cylindrical section 51.
Cylindrical section 51 and the preferred integrated molding of clamping part 52, can be easy to process with save the cost, naturally it is also possible to separately system
It makes, then use is welded or other are fixedly connected with mode and are attached.
Workpiece includes lead screw 3 and nut 4, and nut 4 includes column part 41 and end cap portion 42, wherein end cap portion 42
End surface shape and groove 55 be adapted, 3 both ends of lead screw are provided with fixation hole (not shown) along central axis.The circle of nut 4
The cylindrical surface of post part 41 and the outer peripheral surface of end cap 42 are the surfaces of processing to be ground.
Wherein, the wall thickness of end cap portion 42 is slightly larger than the depth of groove 55, also can be set into identical.
Although the quantity in the present embodiment in connecting rod 53 and pillar 12 is 1, also can be set mutually matched
It is multiple, so that transmission is more steady.
Installation process: the big major diameter ball (steel ball) of the steel ball size being adapted to when by than working normally is put into nut 4
Raceway in, be then threaded into lead screw 3, eliminate the gap between lead screw 3 and nut 4；The insertion of end cap portion 42 of nut 4 is solid
It holds in the groove 55 of device 5, while lead screw 3 passes through in the through-hole 56 of holding unit 5, tightening screw (clamp device 54) is by lead screw
3, nut 4 and holding unit 5 are fixed together；The distance between the first chuck 1 and the second chuck 2 are adjusted, by 3 both ends of lead screw
Fixation hole is respectively aligned to first top 11 and second top 21, then adjusts the first chuck 1 and the second chuck 2 withstands lead screw 3, so
Afterwards, connecting rod 53 is stirred to be brought to abutment against on the pillar 12 of the first chuck 1；The first chuck 1 and the second card are driven by driving device
Disk 2 rotates, and then drives workpiece to rotate together by pillar 12, so cylindrical surface to nut 4 and outer peripheral surface carry out grinding plus
Work.After processing is completed, workpiece is disassembled from tooling, then screws out lead screw, remove major diameter ball, then change normal work
As when the ball of size that is adapted to.
In order to clearly illustrate to eliminate the principle in gap, herein for example: set the ball diameter of normal use as D0, example
Such as D0=10mm, raceway diameter DT, such as DT=12mm, the diameter of major diameter ball are DB, such as DBFor 13mm；It works normally
When, the diameter D of ball0The diameter D of < racewayT, i.e., there are gaps between lead screw and nut；In the processing side of the nut of the present embodiment
In method, using the ball of major diameter, i.e. DBThe diameter D of > racewayT, using interference fit lead screw and nut, then again together
It is packed into tooling and then is processed.The diameter of major diameter ball can according to need flexible choice, as long as guaranteeing that ball diameter is big
In or slightly larger than raceway diameter, the purpose for eliminating gap can be realized.
The invention also discloses a kind of processing methods, for processing outer circle and the end face of the nut of ball-screw, step 1:
The big major diameter steel ball of the steel ball size being adapted to when by than working normally is put into the raceway of nut 4, is then threaded into lead screw 3；
Step 2: lead screw 3 and nut 4 that prepackage prepares being packed into tooling together, and are fixed to each other, wherein lead screw 3 passes through the logical of tooling
The central axis in hole, the through-hole of the central axis and tooling of lead screw 3 is overlapped；Step 3: tooling being installed on lathe, by driving
Device drives lead screw 3, nut 4 and tooling to rotate together, and then processes to the cylindrical surface and outer peripheral surface of nut 4.
The description that the specific illustrative embodiment of the present invention is presented in front is for the purpose of illustration and description.Front
Description be not intended to become without missing, be not intended to limit the invention to disclosed precise forms, it is clear that root
It is possible for much changing and change all according to above-mentioned introduction.The exemplary embodiment was chosen and described for the sake of explain this hair
Bright certain principles and practical application, so that others skilled in the art can be realized and utilize of the invention each
Kind illustrative embodiments and its different selection forms and modification.The scope of the present invention be intended to by the appended claims and
Its equivalent form is limited.
