Specific embodiment
This Macro/Mini switch fixture disclosed in the present embodiment, be applied to clamping standard 3R stick, standard 3R stick it is straight
Diameter is 20mm.
As shown in Figure 1, this switch fixture includes clamp head 1, conversion sheet 2 and standard Macro locating plate 3.In conjunction with Fig. 1 to figure
5 as can be seen that clamp head 1 includes outer sleeve body 11 and pipe sleeve 12.
The pipe sleeve 12 of the present embodiment is the round tube of wolfram steel material, and wall thickness is selection 2mm, and inner hole 12-1 is smooth hole, surface
Roughness requirements are at least up to Ra0.1, and diameter of bore is Φ 200 +0.005mm。
The outer sleeve body 11 of the present embodiment is the T shape pole of ordinary carbon steel material, the aperture ratio pipe sleeve 12 of axial center hole
The small about 0.025mm of outer diameter.
After being heated to outer sleeve body 11 by 12 hot charging of pipe sleeve in its axial center hole, after outer sleeve body 11 is cooling, pipe sleeve 12
Outer wall can with 11 inner wall of outer sleeve body realize fit closely.
Wolfram steel material hardness is high and has good wearability, the clamping repeatedly of adaptable standard 3R stick and disassembly.
After outer sleeve body 11 and 12 hot charging of pipe sleeve form single piece, in a plurality of radial slot 1- of the ipsilateral processing of 11 outer wall of outer sleeve body
1 and axial groove 1-2, the central angle of every radial slot 1-1 take 178 degree, and radial slot 1-1 and axial groove 1-2 are in I-shaped arrangement.
In conjunction with Fig. 1 to Fig. 4 it can be seen that the radial slot 1-1 of the present embodiment has four, wherein one and bottom topmost
One has certain distance with the top and bottom of clamp head respectively.From top to bottom, first and Article 2 radial slot arc length
Middle position processes first axial groove 1-2, processes Article 2 axial groove 1-2, i.e. shape between third and fourth radial slot
At two " work " words, so as to form two gripping sections.
The entity of two two sides axial groove 1-2 has the horizontal threaded bore 1-3 to connect respectively, is configured with water in horizontal threaded bore
The clamping force of flat fastening bolt 4, horizontal fastening bolt 4 passes to pipe sleeve 12, and pipe sleeve 12 is made to generate micron order deformation.
The one circle circular hole 1-4 of step surface processing of clamp head 1, for connecting conversion sheet 2.From fig. 5, it can be seen that a circle is uniformly distributed
There is several circular holes 1-4.The outer diameter of conversion sheet 2 is identical as the step surface diameter of clamp head 1, has a circle corresponding to step surface thereon
Threaded hole 2-1, as shown in Figure 6.
Fastening screw LD is screwed into the threaded hole 2-1 in conversion sheet after the circular hole 1-4 of 1 step surface of clamp head, makes to press from both sides
The top surface of the bottom surface and conversion sheet 2 that have caster bed terrace fits closely.
This switch fixture realizes switching by conversion sheet 2, passes through fastening spiral shell between conversion sheet 2 and standard Macro locating plate 3
Follow closely LD connection fastening.I.e. conversion sheet 2 play a part of accept clamp head 1 and with standard Macro locating plate 3.
The threaded hole 2-2 for thering is a circle to manufacture in conversion sheet 2 according to screw mounting hole is fastened on standard Macro locating plate 3, from
Fig. 6 can be seen that this circle threaded hole and be located at the radius that radius is less than conversion sheet 2 and 1 connected circular hole circle of clamp head, and a circle is evenly equipped with
4 threaded holes, it will be seen from figure 1 that in conversion sheet 2 ringlet threaded hole aperture be less than standard Macro locating plate 3 on fasten spiral shell
Macro/Mini switching clamp can be improved in this way by constantly regulate the loose gripping position of fastening screw LD in the aperture of nail mounting hole
Has the assembly precision in assembling link.Fastening screw LD is screwed into conversion after passing through the screw mounting hole on standard Macro locating plate 3
In threaded hole 2-2 on piece 2, fit closely conversion sheet 2 and standard Macro locating plate 3.
Standard 3R stick is inserted into the inner hole 12-1 of 1 pipe sleeve 12 of clamp head when installing on this switch fixture, and lower end is by turning
The limit of piece 2 is changed, the power being computed then is applied by torque spanner respectively, horizontal fastening bolt 4 is rotated, makes it by axial groove
The entities of the two sides 1-2 tenses, to transmit the force to pipe sleeve 12, until pipe sleeve 12 reach preset Light deformation amount (generally-
0.007mm), standard 3R stick is clamped, operation is simple and reliable, executes system without being equipped with complicated force, input cost is low.
Standard 3R stick provides biggish chucking power by the horizontal fastening bolt 3 in upper and lower many places, can meet and reach preset change
Shape amount；In addition, horizontal fastening bolt 3 can be such that standard round bar is positioned twice up and down, so as to improve its positioning linear degree, make
Process Plays pole axis is not easy inclination and distortion, guarantees that the mould parts precision processed is higher.
When replacement, standard 3R pole can be extracted by unclamping horizontal fastening bolt, convenient and efficient.
It is also possible to apply the invention to the clampings of other diameter criteria poles.
When the diameter of standard round bar is 20~Φ of Φ 30mm, the setting of radial slot and axial groove can refer to this on outer sleeve body
Two " work " words are arranged in embodiment, form two gripping sections.
When the diameter of standard round bar is 30~Φ 40 of Φ, it can refer to the present embodiment and six radial slots and 3 axial directions be set
Slot, i.e. three I-shapeds are at three gripping sections, to provide bigger clamping force, it is ensured that clamping effect.
When the diameter of standard round bar be≤Φ 20 perhaps >=Φ 40 when as the case may be reduce or increase radial slot and
Axial groove, the micron order for meeting and setting of being subject to deform.
In conclusion present invention has the advantage that
1, structure is simple, low manufacture cost, combination bonding strength is high, is convenient for assembling adjustment and disassembly, meets precision use
It is required that and economical and practical.
2, pipe sleeve uses wolfram steel (hard alloy) material, and hardness is higher than standard round bar, meets the frequent use of machining,
And inner hole is not easy abrasion deformation, guarantees that the mould parts precision processed is higher, reduces the turnover rate of clamp head, reduces maintenance expense
With to reduce production cost.
3, standard round bar is clamped by way of screwing horizontal fastening bolt and pipe sleeve is made to generate Light deformation.Electric machining,
In the processes such as numerical control lathe/milling/mill, since above-mentioned fixture round hole axial center and Marco holder axis central coaxial degree exist
0.003mm is hereinafter, being not only able to achieve the quick-clamping of components to be processed while can also improve assembly precision and processing quality.
