Abstract
The utility model provides a scroll compressor with a stationary disc capable of inching axially. The scroll compressor comprises a main case, the stationary disc, a movable disc, an eccentric bushing, a crankshaft and a front cover. One end of the main case is an exhaust end; the other end of the main case is connected with the front cover; after mutual insertion, the movable disc and the stationary disc are disposed in a space formed by the main case and the front cover; and the eccentric bushing is installed in the movable disc and is connected with the crankshaft which is connected with a driving device. The scroll compressor is characterized in that the rear end of the stationary disc is provided with at least three pin holes; the main case is provided with corresponding pin holes in corresponding positions; one end of each pin is installed in one pin hole in the stationary disc or one pin hole in the main case fixedly and the other end of the pin is inserted in one pin hole in the main case or one pin hole in the stationary disc movably; and, under propelling of exhaust pressure and guidance of the pins and the pin holes, a profile end face of the stationary disc inches axially and is thus in seal fit with a profile end face of the movable disc. The scroll compressor has the advantages of simple structure, easy assembly, and a good seal effect.
Description
Technical field
The utility model relates to a kind of scroll compressor, the especially a kind of clutch transmission easy to assembly simple in structure or the scroll compressor of driven by motor, and specifically a kind of quiet dish easy to assembly can axially fine motion formula scroll compressor.
Background technique
As everyone knows, in scroll compressor, quiet dish is fixedly mounted in the casing; Moving plate is inserted in the quiet dish and through preceding cap assemblies and is positioned in the casing, in order to guarantee can to do relative movement between Moving plate and the quiet dish, has the better seal effect again; Therefore, require during assembling quiet dish inner bottom surface between the casing end face apart from B greater than the protecgulum flanged surface to about 0.1 millimeter 0＜(B-A)＜0.1 millimeter of the distance A between the Moving plate end face, because the processing and the existence of directional error; Be difficult in the actual device guarantee, therefore, when assembling, must measure on device limit, limit; And control this gap through the method that installs pad additional; This just causes installation efficiency very low, and is necessary for the pad that each station outfit thickness does not wait, when not only increasing the rigger; And the increase cost of parts, this problem is restricting the raising of scroll compressor assembling effect for a long time always.
Summary of the invention
The purpose of the utility model is that the assembly period that exists when being directed against existing scroll compressor sound dish device is long; The unmanageable problem in gap; Design a kind of pad that need not, only need the quiet dish height of control just can realize that the quiet dish easy to assembly that self adaption cooperates can axially fine motion formula scroll compressor.
The technological scheme of the utility model is:
A kind of quiet dish can axially fine motion formula scroll compressor; Comprise casing 8, quiet dish 6, Moving plate 5, eccentric bushing 4, bent axle 2 and protecgulum 3; One end of casing 8 is an exhaust end; Its other end links to each other with protecgulum 3, is installed in after Moving plate 5 and quiet dish 6 interfix in the space of casing 8 and protecgulum 3 compositions, and eccentric bushing 4 is installed in the Moving plate 5 and with bent axle 2 and links to each other; Bent axle 2 links to each other with drive unit 1; It is characterized in that establishing at least 3 pin-and-holes behind the rear end of described quiet dish 6, also have corresponding pin-and-hole at casing 8 corresponding position sheets, an end of pin 11 fixedly is inserted in the pin-and-hole or the pin-and-hole on the casing 8 on the quiet dish 6; Pin 11 the other end is actively plugged in the pin-and-hole or the pin-and-hole on the quiet dish 6 on the casing 8, thus the molded lines end face of quiet dish 6 exhaust pressure promote and sell 11 and the leading role of pin-and-hole under do axial fine motion and fit with the molded lines end face seal of Moving plate.
Described drive unit 1 is clutch or motor.
The quantity of described pin 11 is 4.
Seal ring 12 is installed between the surface of contact of the bottom surface of described quiet dish 6 and casing 8.
The beneficial effect of the utility model:
The utility model realizes that through the pressure of relief opening the axial little of quiet dish moves; Thereby make quiet dish and Moving plate reach the optimal seal fiting effect; Only need (as can the pin-and-hole on the quiet dish being aimed at the pin on the casing) in the pin-and-hole on the insertion of the pin on the quiet dish casing can be accomplished the device of quiet dish during assembling, and because the height of quiet dish is controlled, Moving plate need not to measure and install additional pad when installing; Not only improve efficiency of assembling, and reduced part number.The processing of pin and pin-and-hole then utilizes common process equipment to realize.
The utility model can improve efficiency of assembling more than 10 times.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Embodiment one.
Shown in Fig. 1-2.
A kind of quiet dish can axially fine motion formula scroll compressor, comprises casing 8, quiet dish 6, Moving plate 5, eccentric bushing 4, bent axle 2 and protecgulum 3, and an end of casing 8 is an exhaust end; Its other end links to each other with protecgulum 3; Be installed in after Moving plate 5 and quiet dish 6 interfix in the space that casing 8 and protecgulum 3 form, eccentric bushing 4 is installed in the Moving plate 5 and with bent axle 2 and links to each other, and bent axle 2 links to each other with clutch 1 as drive unit; Establish at least 3 pin-and-holes behind the rear end of described quiet dish 6; Be 4 pin-and-holes among Fig. 2, also have corresponding pin-and-hole at casing 8 corresponding position sheets, an end of pin 11 fixedly is inserted into (Fig. 1,2) in the pin-and-hole on the quiet dish 6 through interference fit; The other end of pin 11 can directly be actively plugged in the pin-and-hole on the casing 8 when device; Quiet like this dish can be done axial little moving under the guiding of pin 11, circumferential then sell under 11 the restriction and can not rotate at least 3, during practical implementation; Pin 11 also interference fit is fixed in the pin-and-hole on the casing 8, and it is right directly the pin-and-hole on the quiet dish to be aimed at pin fixing on the casing 8 11 during assembling.Thereby the molded lines end face of quiet dish 6 exhaust pressure promote and sell 11 and the leading role of pin-and-hole under do axial fine motion and fit with the molded lines end face seal of Moving plate.In addition, between the surface of contact of the bottom surface of quiet dish 6 and casing 8, seal ring 12 is installed also.Present embodiment other do not relate to partly all identical with existing technology or identical in the related patent U.S. Patent No. of first to file with the claimant.
