Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of air-conditioner compressor crankshaft fixture, including base plate 1 and hold down gag
8, also include first adjustment block the 2, second adjustment block 3, eccentric part positioning seat 4, trunnion positioning seat the 5, first alignment pin 6 and
Two alignment pins 7, described first adjustment block 2 and the second adjustment block 3 be arranged on base plate 1, and described eccentric part positioning seat 4 is arranged on
In first adjustment block 2, two the first alignment pins 6 are installed between described eccentric part positioning seat 4 and the first adjustment block 2, described
Trunnion positioning seat 5 is arranged in the second adjustment block 3, is provided with two between described trunnion positioning seat 5 and the second adjustment block 3
Second alignment pin 7, described trunnion positioning seat 5 has trunnion locating slot 5a, and described eccentric part positioning seat 4 has eccentric part
Dividing locating slot 4a, described hold down gag 8 and trunnion positioning seat 5 are for removably connecting.
As shown in Figure 6 and Figure 7, described first adjustment block 2 has the installation portion interference fit having with the first alignment pin 6
The first dowel hole 2a, have the location division interference fits having with the first alignment pin 6 bottom described eccentric part positioning seat 4
The 3rd dowel hole 4b, described second adjustment block 3 has the second of the installation portion interference fit having with the second alignment pin 7
Dowel hole 3a, has the 4th of the location division interference fits having with the second alignment pin 7 and determines bottom described trunnion positioning seat 5
Position pin-and-hole 5b.The trunnion 9b that described trunnion locating slot 5a has with bent axle 9 mates: trunnion locating slot 5a can position master
The external cylindrical surface of axle journal 9b, makes the central axis of trunnion 9b position；Described eccentric part locating slot 4a is inclined with what bent axle 9 had
Heart part 9a is mated: eccentric part locating slot 4a front-back can be with location eccentricity part 9a external cylindrical surface, with trunnion locating slot
5a positions bent axle 9 together so that it is can not rotate, two ends of face, left and right location eccentricity part 9a of eccentric part locating slot 4a
Face so that it is can not move axially.Described eccentric part positioning seat 4 passes through the first alignment pin 6 location and installation in the first adjustment block 2
On, described trunnion positioning seat 5 by the second alignment pin 7 location and installation in the second adjustment block 3, by described first adjustment block 2 He
When second adjustment block 3 is arranged on base plate 1, finely tunes the first adjustment block 2 and the second adjustment block 3 makes eccentric part locating slot 4a and master
Axle journal locating slot 5a aligns, and makes the placement that bent axle 9 can be correct, namely the central axis location of trunnion 9b, eccentric part 9a
Snapping in eccentric part locating slot 4a, bent axle 9 is the most all positioned, it is impossible to mobile.
During enforcement, first unclamp hold down gag 8, bent axle 9 accurately put into eccentric part positioning seat 4 and trunnion positioning seat 5,
Making eccentric part 9a snap onto eccentric part locating slot 4a, trunnion 9b puts into trunnion locating slot 5a, finally makes compression fill
Put 8 compression trunnion 9b, make trunnion 9b external cylindrical surface be close to the locating surface that trunnion locating slot 5a has.Only need in processing partially
Respective pin-and-hole and the relative positional accuracy of locating slot and each self-align is ensured when heart part positioning seat 4 and trunnion positioning seat 5
The precision of groove, once eccentric part positioning seat 4 or trunnion positioning seat 5 produce abrasion or damage, and only need to pull down old positioning seat,
Change new positioning seat, positioned by alignment pin, it is not necessary to may continue to use by adjustment.Need the size bent axle that clamping is new
Time, only need to do a set of matched eccentric part positioning seat 4 and trunnion positioning seat 5, be positioned by alignment pin, load onto new
Eccentric part positioning seat 4 and trunnion positioning seat 5 can realize the clamping to new size bent axle.
In sum, this utility model air-conditioner compressor crankshaft fixture includes eccentric part positioning seat 4 and trunnion location
Seat 5, both convenient processing, difficulty of processing is low, low cost；Employ again the first alignment pin 6 and the second alignment pin 7, make eccentric part
Positioning seat 4 and trunnion positioning seat 5 is divided to change easily；Having only to change positioning seat can corresponding various sizes of compressor of air conditioner
The clamping of bent axle.
Described hold down gag 8 can use wedge-shaped clamping, eccentric clamping, helical clamping, pneumatic pinch etc., uses wedge grip
Tightly, eccentric clamping, pneumatic pinch and electronic clamping, structure is the most more complicated, and cost is the highest, and it is not the most square for using on lathe
Just, especially pneumatic pinch needs to provide source of the gas, is not suitable for the processing environment that automaticity is the highest and complicated, in order to make pressure
Tight device 8 simple in construction is effective, reduces cost, and further, as shown in Figure 1, Figure 2 with shown in Fig. 5, described hold down gag 8 includes V-arrangement
Compact heap 8a, studs 8b and nut 8c, described studs 8b lower end is arranged on trunnion positioning seat 5, described double end
The up/down perforation hole that stud 8b has through V-arrangement compact heap 8a, described nut 8c is arranged on studs 8b upper end, adjusting nut
8c makes V-arrangement compact heap 8a compress downwards the trunnion 9b that bent axle 9 has, and after installing bent axle 9, only needs fastening nut 8c by V
The V-shaped groove face that shape compact heap 8a has compresses the external cylindrical surface of trunnion 9b.
For more reliable compression bent axle 9, further, described V-arrangement compact heap 8a has two pieces, is separately positioned on bent axle 9
The two ends of the trunnion 9b having, compress the two ends of trunnion 9b simultaneously, make clamping relatively reliable.
