If Fig. 1 is to, as shown in 3, including handle 10 according to the coil winding machine collet chuck of the present invention, this handle is attached to axle 2 by arbor assembly and combines rotation with axle 2.Handle 10 is a kind of bar portion as main body.By handle, the parts of composition coil winding machine collet chuck 1 are coupled to each other.
More particularly, coil winding machine collet chuck 1 includes: handle 10, and this handle includes forming the connection part 11 located in its back-end, and it couples with arbor assembly 4；Convergent portion 20, this convergent portion is formed at the front end place of handle 10, and is tapered towards the rear end of handle 10；Acceptance division 30, this acceptance division is formed in the front end in convergent portion 20, and includes the entrance 31 being wherein fitted with capacitor；And multiple slit 40, slit is formed in acceptance division 30, to travel rearwardly from acceptance division 30.Collet chuck also includes multiple clamping section 32a, 32b, and they are formed on the inwall 33 of acceptance division 30 and position with different angles.
Therefore, collet chuck 1 operates as follows.The connection part 11 of handle 10 is inserted into arbor assembly 4, and capacitor 3 is placed in the entrance 31 of acceptance division 30.Then, when pulling back axle 2, cause the interference between the holder of convergent portion 20 and arbor assembly 4, the diameter of result collet chuck 1 is reduced by slit 40, and thus make the inwall district of acceptance division 30 reduce, thus utilize any one clamping section 32a, 32b of being formed at acceptance division 30 place to clamp capacitor 3.
Hereafter, axle 2 is rotated by spindle motor.Therefore, coil winding machine collet chuck 1 is wound around coil around capacitor 3 while rotating.
In this respect, because clamping section 32a, 32b clamp capacitor 3 by inwall 33, inwall 33 can wear and tear due to Reusability, thus reduces the clamping force for clamping capacitor 3.Now, collet chuck is generally with new replacement.On the contrary, because including multiple clamping section 32a, 32b according to the coil winding machine collet chuck 1 of the present invention, it can pass through to use any one to use but without clamping section 32a, 32b of being worn for more time.
Coil winding machine collet chuck 1 including handle 10, convergent portion 20 and acceptance division 30 can preferably be manufactured by typical metal.It is highly preferred that collet chuck can be manufactured by high-carbon chromium steel (SUJ2), it has the hot strength of excellence, elasticity and wearability.Most preferably, collet chuck nickel plating can polish effect and corrosion resistance to provide.
Meanwhile, although the inwall 33 of composition clamping section is general and acceptance division 30 is one-body molded, inwall 33 can also independent molding, then pass through bolt and be detachably fixed to acceptance division 30.Adopting independent manufacture, the proportion of goods damageds of collet chuck 1 can minimize.In this respect, inwall 33 is preferably manufactured by hard alloy.
Will be described in detail with reference to accompanying drawings now embodiments of the invention.
As it is shown in figure 1, coil winding machine collet chuck 1 according to embodiments of the present invention is configured to have on the whole cylinder body shape.More particularly, the handle 10 being of a size of Ф 6mm × long 42mm is prepared by high-carbon chromium steel (SUJ2), and left hand thread portion is formed on the rear end of handle 10, thus provides the connection part 11 for coordinating with arbor assembly 4.
Form the size of diameter Ф 14mm, rear diameter Ф 6mm and length 7mm before the convergent portion 20 at handle 10 front end place is configured to have.In other words, convergent portion 20 expands forward around the axis of handle 10 with the angle of 150 °.
As shown in Figures 2 and 3, therefore convergent portion 20 is configured to have conical by its shape on the whole.Therefore, when pulling back axle 2, the diameter in convergent portion 20 reduces due to slit 40, thus makes convergent portion 20 be inserted easily in the holder 4a of arbor assembly 4.Now, axle 2 can more easily be taken out from the holder 4a of arbor assembly 4.
Forming the size that the acceptance division at front end place of convergent portion 20 is configured to have Ф 11mm × long 11mm, and be provided with entrance 31 at its front end place, capacitor 3 is partially received in this entrance.Form the slit 40 that four length is 36mm through convergent portion 20 from acceptance division 30 towards handle 10 rear end, therefore, they can be replaced mutually.
It will be appreciated that from Fig. 4, seeing such as the entrance 31 towards acceptance division 30, slit 40 is formed with the angle interval of 90 °, and the C place, center of slit 40 is formed with the cylindrical hole of Ф 2.5mm, cause when the diameter of acceptance division 30 reduces, each fan portion non-interference that slit 40 limits.
As shown in Figures 4 and 5, multiple clamping section 32a, 32b of being formed in acceptance division 30 obtain by this way, that is: the front end face of acceptance division 30 is formed at entrance 31 place, there is square recess to provide four inwalls 33, and form four other inwalls 33 further to provide other inwall 33.
In order to significantly more understand and describe multiple clamping section 32a, 32b, it is the first clamping section 32a that a 32a in multiple clamping sections will be called, and four inwalls 33 forming the first clamping section 32a will to be called be first inwall 33a, 33b, 33c, 33d.Meanwhile, it is the second clamping section 32b that other clamping section 32b will be called, and four inwalls 33 forming the second clamping section 32b will to be called be second inwall 33e, 33f, 33g, 33h.
First clamping section 32a is formed as having the square shape identical with capacitor 3 by this way, that is: the square recess of the size with high 0.95mm × length of side 8-8.5mm is formed at the front end place of acceptance division 30, causes the corner of first inwall 33a, 33b, 33c, 33d to overlap with slit 40.Therefore, when the diameter of acceptance division 30 reduces, in first inwall 33a, 33b, 33c, 33d, the length of side of each is decreased to 8mm or less, and thus clamping is fitted in the capacitor 3 in entrance 31.
Second clamping section 32b is formed as having the square shape relative to the first clamping section 32a anglec of rotation 45 ° by this way, that is: in first inwall 33a, 33b, 33c, 33d, each is formed with the recess in triangular part cross section in the place of putting wherein, thus provides second inwall 33e, 33f, 33g, 33h.Therefore, the first clamping section 32a and the second clamping section 32b shares major part inner space mutually.
Result, because first inwall 33a, 33b, 33c, 33d weares and teares, the first clamping section 32a clamps capacitor 3, and coil is wound around around capacitor 3, when clamping capacitor 3 and having any problem, collet chuck 1 or capacitor 3 are rotated 45 °, then use the second clamping section 32b to clamp capacitor 3.
First inwall 33a, 33b, 33c, 33d and the second inwall 33e, 33f, 33g, 33h actually play the effect of clamping capacitor 3, and they tilt with the angle of 70-80 ° at the front end face with the acceptance division 30 of the axes intersect of axle 2.
Therefore, in first inwall 33a, 33b, 33c, 33d and the second inwall 33e, 33f, 33g, 33h, each has the staggered portion of dentation, so that the end of inwall is engaged and clamps the capacitor 3 being arranged in entrance 31, it is therefore prevented from surface contact and the common sliding phenomenon that causes.
First inwall 33a, 33b, 33c, 33d and the second inwall 33e, 33f, 33g, 33h angle be limited in the reason of 70-80 ° and be in that, if angle is just not easy occlusion and clamping capacitor 3 more than 80 °.In other words, as broad as long compared with the situation that angle is 90 °.
Meanwhile, if angle is lower than 70 °, the first inwall 33a, 33b, 33c, 33d and the second inwall 33e, 33f, 33g, 33h ora terminalis can be excessively sharp, its result be clamping capacitor 3 process in, stability reduce or capacitor 3 damaged.
As shown in Figure 6, the angle of 75 ° is formed relative to the front end face of acceptance division 30 according to the first inwall 33a of this embodiment, 33b, 33c, 33d and the second inwall 33e, 33f, 33g, 33h, with the axes intersect of axle 2.Therefore, when clamping section 32 is configured with the length of side of 9mm, the length of side of entrance 31 is defined as 8.5mm.
While the preferred embodiment to the invention has been described in detail, but this description is only for illustrative purposes, and the coil winding machine collet chuck according to the present invention is not limited to this description.Those skilled in the art are it is further appreciated that in the case of without departing from the spirit and scope, it is possible to the present invention is made various changes and revises.
All changes and amendment drop in set and the scope of claim, and the particular range of the present invention is limited by dependent claims.
