Shape, ensures the structural strength and stability of air cylinder support 3.Specifically, the two ends of metallic plate can be stamped and formed out lock part 32 respectively
With auxiliary section 33, air cylinder support 3 is formed as column, and lock part 32 and auxiliary section 33 are connected to realize the two ends of metallic plate
Self-locking, so as to the manufacturing process of air cylinder support 3 can be simplified so that 3 simple structure of air cylinder support and easy to process, while can ensure
The structural stability of air cylinder support 3.
Alternatively, lock part 32 is formed as the dovetail groove of the one end for being located at metallic plate, and auxiliary section 33 is formed as being located at gold
The dovetail button of the other end of category plate, dovetail are snap-fitted in dovetail groove to realize the self-locking of metallic plate.
In example as shown in Figure 3, dovetail groove is formed as being open from outside to inside the shape for gradually increasing, and needs explanation
, inside and outside finger dovetail groove here is located at the direction of the opening at the edge of metallic plate to the inner of dovetail groove.Dovetail button
Be shaped to and dovetail groove coordinate, when such dovetail groove coordinates in dovetail button, due to the size of the opening of dovetail groove it is less,
Dovetail button cannot be detached from the opening of dovetail groove, so as to be capable of achieving the self-locking of dovetail groove and dovetail button, prevent metallic plate
Launch at two ends.
In some examples of the present utility model, the both sides of the axial direction of air cylinder support 3 can be respectively equipped with fixed plate 36, fixed
Plate 36 is connected with the support of bearing 1 of reciprocating compressor.So as to be conducive to air cylinder support 3 and the installation of frame to fix.In such as Fig. 1
In the example shown in Fig. 3, fixed plate 36 can be two, and two fixed plates 36 are each provided at the bottom of air cylinder support 3 and symmetrical
The fixed plate 36 of both sides two for being arranged on the axial direction of air cylinder support 3 is fixedly connected with frame respectively, so as to improve air cylinder support 3
With the fixing intensity of frame, it is ensured that the stability of air cylinder support 3 and frame.
Alternatively, fixed plate 36 may be provided in the bottom of air cylinder support 3, and fixed plate 36 is by being stamped and formed out on a metal plate.
One end of fixed plate 36 can be connected with air cylinder support 3 and the other end of fixed plate 36 is formed as flat board.As shown in figure 3, fixed plate
36 can be the fins that metallic plate symmetric punching is formed, and thus, can not only ensure that the structure of fixed plate 36 and air cylinder support 3 is strong
Degree, and the processing technique of air cylinder support 3 can be simplified, reduce the rapidoprint and processing cost of air cylinder support 3.
Alternatively, fixing hole (not shown), fixed plate 36 and fixing hole stamping riveting can be provided with installing plate 11.So as to
Facilitate being connected for the support of bearing 1 and air cylinder support 3, and can ensure the support of bearing 1 and air cylinder support 3 structural strength and
Stability.
In some examples of the present utility model, as shown in Figure 4 and Figure 5, the diameter D1 of fixing hole meets:3mm≤D1≤
10mm, fixed plate 36 are located at the wall thickness Tn1 >=0.5mm after the punching press in fixing hole, and 36 stamping riveting of fixed plate is after fixing hole
Fixed part 114 is formed with, fixed part 114 is located at the lower section of fixing hole to fix fixed plate 36, week of the fixed part 114 along fixing hole
To stretching out, the outer peripheral edge of fixed part 114 is with fixing hole outer peripheral edge apart from Tu1 >=0.3mm, the thickness X 1 of fixed part 114
≥0.5mm。
Specifically, when riveting coordinates, press drift of the diameter less than fixed bore dia is arranged on into the side of fixed plate 36,
The side of the support of bearing 1 is arranged on diameter greater than the riveted joint of fixed bore dia, when pressure drift applies stressed to fixed plate 36
When, locally there is plastic deformation in fixed plate 36, and extend along pressure drift force direction, when the distance for extending is more than fixing hole
Depth when, riveted joint to protrude fixed plate 36 part apply pressure, make projection radially extend to form fixed part
114, so that air cylinder support 3 forms interlocking structure with the support of bearing 1 and is fixed together.
In other examples of the present utility model, fixed plate 36 can be riveted using TOX with installing plate 11.Alternatively, such as
Shown in Fig. 6 and Fig. 7, the diameter D2 of circular TOX rivetings point meets:Neck thickness Tn2 at 3mm≤D2≤10mm, and riveting >=
0.5mm, mutual drop lock Tu2 >=0.3mm, bottom thickness X2 >=0.4mm.
Specifically, when riveting coordinates, fixed plate 36 and the support of bearing 1 are placed between pressure drift and correspondence die,
Pressure drift is located at 11 side of installing plate, and correspondence die is arranged on 36 side of fixed plate, when pressing drift to apply pressure, fixed plate 36
There is local plastic deformation simultaneously with the support of bearing 1, and extend along pressure drift force direction, in corresponding die, with
The circular TOX rivetings point for forming interlocking is snuggly mated to together air cylinder support 3 and the support of bearing 1.
In example as shown in Figure 6 and Figure 7, pressure drift can to installing plate 11 apply pressure when, fixed plate 36 and bearing
Support 1 extends along pressure drift force direction, enters in corresponding die.As shown in fig. 7, the diameter D2 of circle TOX riveting points
Meet:Neck thickness Tn2 >=0.5mm at 3mm≤D2≤10mm, and riveting, mutual drop lock Tu2 >=0.5mm, bottom thickness X2 >=
0.4mm.Due to pressing the extruding between drift and die, the radial direction of the riveting point upper end that installing plate 11 is formed is stamped and formed out convex
Edge, the inwall of the riveting point that fixed plate 36 is formed are stamped and formed out corresponding groove, and flange forms interlocking with groove fit, and flange exceeds
The size of the riveting point external diameter that installing plate 11 is formed is mutual drop lock Tu2.Circular TOX rivetings point can be good at 1 He of the support of bearing
Air cylinder support 3 is connected, and can ensure the structural strength and stability of the support of bearing 1 and air cylinder support 3.
It is understood that the assembling mode of air cylinder support 3 and the support of bearing 1 is except selecting above two stamping riveting side
Formula, it is also possible to select welding, screwing or other riveting methods.
