As shown in Fig. 1 to 3, coil winding machine collet chuck according to the present invention comprises handle 10, and this handle is attached to axle 2 by arbor assembly and combines rotation with axle 2.Handle 10 is a kind of bar portions being used 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 comprises: handle 10, and this handle comprises the connection part 11 being formed in its rear end place, and it connects with arbor assembly 4; Convergent portion 20, this convergent portion is formed in 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 comprises the entrance 31 being wherein fitted with capacitor; And multiple slit 40, slit is formed in acceptance division 30, to advance backward from acceptance division 30.Collet chuck also comprises multiple clamping section 32a, 32b, and the inwall 33 that they are formed in acceptance division 30 is located 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, interference between the fixator causing convergent portion 20 and arbor assembly 4, the diameter of result collet chuck 1 is reduced by slit 40, and make the inwall district of acceptance division 30 reduce thus, utilize any one stationary plane 32a, 32b of being formed in acceptance division 30 place to clamp capacitor 3 thus.
After this, axle 2 is rotated by spindle motor.Therefore, coil winding machine with collet chuck 1 rotation while around capacitor 3 winding around.
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 usually with new replacement.On the contrary, because coil winding machine collet chuck 1 according to the present invention comprises multiple clamping section 32a, 32b, it can use the longer time by using any one clamping section 32a, 32b be not also worn.

Meanwhile, although the inwall 33 of composition clamping section is general and acceptance division 30 is one-body molded, inwall 33 also can be independently shaping, is then detachably fixed to acceptance division 30 by bolt.Adopt independent manufacture, the proportion of goods damageds of collet chuck 1 can minimize.In this respect, inwall 33 is preferably manufactured by carbide alloy.
To describe embodiments of the invention in detail by reference to the accompanying drawings now.
As shown in Figure 1, be configured on the whole there is cylinder body shape according to the coil winding machine collet chuck 1 of the embodiment of the present invention.More particularly, the handle 10 being of a size of Φ 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, is provided for the connection part 11 coordinated with arbor assembly 4 thus.
The convergent portion 20 being formed in handle 10 front end place is configured as the size with front diameter of phi 14mm, rear diameter of phi 6mm and length 7mm.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 as and has conical by its shape on the whole.Therefore, when pulling back moving axis 2, the diameter in convergent portion 20 reduces due to slit 40, makes convergent portion 20 be easy to be inserted in the fixator 4a of spindle assemblies 4 thus.Now, axle 2 can more easily be taken out from the fixator 4a of arbor assembly 4.
The acceptance division being formed in front end place of convergent portion 20 is configured as the size with Φ 11mm × long 11mm, and is provided with entrance 31 at its front end place, and capacitor 3 is partly inserted in this entrance.Form through convergent portion 20 slit 40 that four length are 36mm from acceptance division 30 towards handle 10 rear end, therefore, they can be replaced mutually.
Will be appreciated that from Fig. 4, as the entrance 31 towards acceptance division 30 is seen, slit 40 is formed with the angle intervals of 90 °, and the C place, center of slit 40 is formed with the cylindrical hole of Φ 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, the 32b be formed in acceptance division 30 obtains by this way, that is: the front end face of acceptance division 30 is formed in entrance 31 place, there is square recess to provide four inwalls 33, and the inwall 33 that formation four is other is further to provide other inwall 22.
In order to understand more significantly and describe multiple clamping section 32a, 32b, a 32a in multiple clamping section will be referred to as the first clamping section 32a, and four inwalls 33 forming the first clamping section 32a will to be called be first inwall 33a, 33b, 33c, 33d.Meanwhile, other clamping section 32b will be referred to as the second clamping section 32b, 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 with the size of high 0.95mm × length of side 8-8.5mm is formed in the front end place of acceptance division 30, causes the bight 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, clamps the capacitor 3 be fitted in entrance 31 thus.
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, provides second inwall 33e, 33f, 33g, 33h thus.Therefore, the first clamping section 32a and the second clamping section 32b shares most of 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, by rotation 45 °, then use the second clamping section 32b to clamp capacitor 3.
In fact first inwall 33a, 33b, 33c, 33d and second inwall 33e, 33f, 33g, 33h play the effect of clamping capacitor 3, they at the front end face of the acceptance division 30 of the axes intersect with axle 2 with the angular slope of 70-80 °.
Therefore, in first inwall 33a, 33b, 33c, 33d and second inwall 33e, 33f, 33g, 33h, each has the staggered portion of dentation, be engaged to make the end of inwall and clamp the capacitor 3 be arranged in entrance 31, preventing surface contact thus and the common sliding phenomenon caused.
The reason that the angle of first inwall 33a, 33b, 33c, 33d and second inwall 33e, 33f, 33g, 33h is limited in 70-80 ° is, 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 being 90 ° with angle.
Meanwhile, if angle is lower than 70 °, the ora terminalis of first inwall 33a, 33b, 33c, 33d and second inwall 33e, 33f, 33g, 33h can be excessively sharp, consequently 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 first inwall 33a, 33b, 33c, 33d of this embodiment and 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.
Although describe the preferred embodiments of the present invention in detail, this description is only for task of explanation, and coil winding machine collet chuck according to the present invention is not limited to this description.Those skilled in the art can understand further, in the case of without departing from the spirit and scope, can make various changes the present invention and revise.
All changes and revise drop on claim set and scope in, and particular range of the present invention is limited by dependent claims.
