Description
Technical field
The utility model is the location structure of a kind of gear compressor spiral case and cabinet.
Background technique
The spiral case and cabinet of gear compressor generally realize positioning by 2 positioning pins, but with compressor tolerance
Increase, spiral case, the size of cabinet are also increasing, and locating pin structure originally gradually exposes some problems in production,
Affect the repair and maintenance of product quality, production cycle and equipment.
As shown in Figure 1, 2, spiral case 1 in the prior art is with the location structure of cabinet 2 using the fixed spiral case position of 2 positioning pins
It sets, there is the following problem in use:
1) it, since spiral case 1 is relatively deep, needs to grow very much with the knife handle for beating positioning pin 3, the machining accuracy of positioning pin 3 may be influenced；
2) it, is beaten because positioning pin 3 needs to match, therefore 1 other parts of spiral case are after processing is completed, need advanced luggage with positioning, then
It returns again to processing workshop and carries out positioning pin 3 with beating, again return to assembly shop progress compressor complete machine with having beaten after positioning pin
Assembly after installing positioning pin 1, then is withstood with screw 4 to prevent positioning pin 3 from disengaging, finally polishes 4 tail portion of screw；This
Process is relatively complicated, influences production efficiency；
3) after, polishing because of 4 tail portion of screw, screw is difficult to tear open, and there is also subsequent problems not easy to assemble for locating pin structure, i.e.,
Subsequent spiral case 1 is difficult to remove from cabinet 2；And since there may be deformations for disassembly process, the locating pin structure after dismounting
Precision can be worse.
Summary of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, provide a kind of cancellation locating pin structure, adopt
With the structure of branch screw and guide pad, the fixed locking of attaching nut improves product quality and production efficiency；Meanwhile after convenience
The adjustment at continuous spiral case center and by the gear compressor spiral case of the disassembly of spiral case and the location structure of cabinet.
The technical solution of the utility model is as follows: a kind of location structure of gear compressor spiral case and cabinet, described
Spiral case has position locating respectively up and down, and wherein the upper and lower position location structure of spiral case is by branch screw and locking nut
It forms, is provided with a jacking block or an external jacking block on the spiral case ectosome, is screwed with branch screw on the jacking block, it is described
Matched locking nut or adjusting washer (disk) are screwed on branch screw；The left-right position location structure of the spiral case is by being welded on case
Guide pad, left and right branch screw and left and right locking nut composition on body；The left and right branch screw is screwed in guide pad, and
Matched left and right locking nut is screwed on the left and right branch screw.
As preferred: being pushed up by the jacking block or external jacking block of setting by being screwed in the upper and lower position of the spiral case
Upper and lower position between spiral case and cabinet is adjusted and is locked by branch screw and locking nut or adjusting washer (disk) on block；Described
Guide pad and spiral case cooperate, and after spiral case left-right position is adjusted in place, are locked by the left and right branch screw and left and right
The mutual alignment of nut locking guide pad and spiral case.
The utility model is by cancelling locating pin structure, and using the structure of branch screw and guide pad, attaching nut is fixed
Locking improves product quality and production efficiency；Meanwhile facilitating the adjustment at subsequent spiral case center and the disassembly by spiral case.

Fig. 2 is locating pin structure partial enlarged view in Fig. 1.
Fig. 3 is the structural schematic diagram of the utility model.
Fig. 4 is the spiral case left and right directions positioning guide block structure figure of the utility model.
Fig. 5 is A-A cross-sectional view in Fig. 4.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing: shown in Fig. 3, a kind of tooth described in the utility model
The location structure of wheeled compressor scroll and cabinet, the spiral case 1 have position locating respectively up and down, wherein spiral case
1 upper and lower position location structure is made of branch screw 5 and locking nut 6, be provided on 1 ectosome of spiral case a jacking block 7 or
An external jacking block is screwed with branch screw 5 on the jacking block 7, is screwed with matched locking nut on the branch screw 5
6 or adjusting washer (disk) 8.
Fig. 4, shown in 5, the left-right position location structure of the spiral case 1 by be welded on cabinet guide pad 9, left and right support top
Screw 10 and left and right locking nut 11 form；The left and right branch screw 10 is screwed in guide pad 9, and in the left and right support top
Matched left and right locking nut 11 is screwed on screw 10.
As preferred embodiment, jacking block 7 or external top of the upper and lower position of spiral case 1 of the present invention by setting
Block, will be upper and lower between spiral case 1 and cabinet 2 by the branch screw 5 being screwed on jacking block 7 and locking nut 6 or adjusting washer (disk) 7
Position adjusts and locks；The guide pad 9 and spiral case 1 cooperates, and after 1 left-right position of spiral case is adjusted in place, by described
Left and right branch screw 10 and left and right locking nut 11 lock guide pad 9 and spiral case 1 mutual alignment.
Embodiment: the structure that the utility model takes left and right to spiral case and positions respectively up and down, wherein Fig. 3 is on spiral case
Lower position locating figure, wherein the lower part B block of Fig. 2 is cross sectional plan view, and C, D block are structure vertical direction detail drawing.Snail
1 up and down direction of shell is located through branch screw 5 to adjust, and is fixed after mixing up with locking nut 6；Jacking block 7 for connection can
With cast on 1 ectosome of spiral case (as shown in C block), can also be realized by external jacking block (as shown in D block), at this time jacking block
7 are fixed on spiral case 1 by branch screw 5 and adjusting washer (disk) 8.
Fig. 4,5 show spiral case left and right directions positioning guide block structure figure, tab order are as follows: first that guide pad 9 is fixed
On cabinet 2, then spiral case 1 and guide pad 9 are cooperated, after 1 left-right position of spiral case is adjusted in place, tighten two sides or so support top
Then screw 10 tightens 11 locked and fixed of left and right locking nut.
The utility model matches the process of positioning pin of beating because eliminating, spiral case 1 can time processing in place, avoid in assembly and give birth to
Rotation between production, while without the manual grinding for carrying out positioning pin Zhi Dingyong bolt tail, substantially increase the effect of production
Rate shows can to effectively shorten 1 ~ 1.5 working day of life cycle of the product through actual use, greatly facilitate assembly and plus
Work；And spiral case is significantly improved with the more former locating pin structure of cabinet positioning accuracy.
