Abstract
The cylinder seat blank for the refrigeration compressor comprises a cylinder seat body, wherein a silencing cavity, a shaft seat and a cylinder part are formed on the cylinder seat body, and a fabrication hole is formed in the cylinder part. The utility model discloses a cylinder block blank directly casts out the fabrication hole when the casting, and reducible cylinder block blank material reduces later stage cylinder block work load simultaneously, effective the cost is reduced to sew with long stitches when can avoiding the piston hole of honing with long stitches the grinding pole and take place to warp, thereby improve the precision of honing with long stitches.
Description
Technical field
The utility model belongs to the Compressor Technology field, relates in particular to the blahk structure of the cylinder block that uses on a kind of refrigeration refrigerator compressor.
Background technique
Reciprocating type refrigeration compressor generally includes housing, be arranged at motor in the housing, by the bent axle of driven by motor, have cylinder cylinder block, be arranged at piston in the cylinder, connect the connecting rod of piston and bent axle, connecting rod passes to piston with the Driving force of bent axle, makes piston reciprocating in cylinder.Usually this connecting rod comprises the large circular column that is connected with bent axle, the little circular column that is connected with piston and the body of rod that connects large circular column and little circular column, circular hole and connecting rod that bent axle passes on the large circular column fix, and little circular column is inserted in the piston cavity and by pin and connecting rod and fixes.
The freezer compressor connecting rod adopts the integrated type connecting rod more at present, for the ease of installing connecting rods, need to auxiliary hole be set on cylinder block top, and common auxiliary hole is the U-shaped gap structure.See figures.1.and.2, Fig. 1 is the blahk structure schematic representation of a kind of cylinder block in the prior art, and Fig. 2 is the structural representation after the cylinder block fine finishing.The cylinder section 101 of cylinder block blank is solid cylinder, so cylinder section 101 materials are more, and cost is higher, also causes when cylinder section 101 processing U-shaped breach 102 and piston hole 103 workload larger.Simultaneously because after cylinder section 101 offers U-shaped breach 102, because the existence of this U-shaped breach 102, when carrying out hone piston hole 103, cutter can be subject to asymmetrical cutting force, micro-strain can occur because of unbalance stress in hone rod end head, this asymmetrical cutting force not only affects cutting-tool's used life, and can be influential to the finishing size of cylinder block, affects the hone precision.
The model utility content
The purpose of this utility model provides a kind of novel cylinder block blahk structure, can reduce the workload that cylinder block adds man-hour, reduces cost, and can guarantee the precision of piston hole hone.
To achieve these goals, the utility model is taked following technical solution:
A kind of refrigeration compressor cylinder block blank comprises the cylinder block body, forms silencing cavity, axle bed and cylinder section at described cylinder block body, forms auxiliary hole in the described cylinder section.
The degree of depth of auxiliary hole of the present utility model is greater than the diameter of piston hole.
Auxiliary hole of the present utility model is U-groove bevel.
The upper extreme point of auxiliary hole of the present utility model bottom is positioned at the below of piston hole bottom lower extreme point.
By above technological scheme as can be known, cylinder block blank of the present utility model directly casts out U-groove bevel (auxiliary hole) when casting, not only can reduce cylinder block blank materials, can reduce simultaneously the amount of finish of later stage cylinder block, effectively reduce cost, the hone bar deforms in the time of can also avoiding the hone piston hole, thereby improves the hone precision.
Description of drawings
Fig. 1 is the schematic representation of a kind of cylinder block blahk structure in the prior art;
Fig. 2 is the structural representation after the fine finishing of prior art cylinder block;
Fig. 3 is the schematic representation of an embodiment's of the utility model cylinder block blahk structure;
Fig. 4 is the structural representation after the fine finishing of the utility model cylinder block.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in more detail.
Embodiment
As shown in Figure 3, cylinder block blank of the present utility model comprises cylinder block body 1, and casting has silencing cavity 1-1, axle bed 1-2 and the 1-3 of cylinder section on cylinder block body 1.In order to reduce the post-production amount of piston hole, cylinder block body 1 of the present utility model directly casts out U-groove bevel 1-4 at the 1-3 of cylinder section when casting, and the degree of depth of U-groove bevel 1-4 is greater than the diameter of piston hole.Because the degree of depth of this U-groove bevel 1-4 is greater than the piston hole diameter, therefore after post-production goes out piston hole, U-groove bevel 1-4 can extend to the piston hole below, so that the piston hole upper and lower sides all is distributed with breach, on the one hand leaving surplus can simply process, on the other hand when later stage fine finishing, and cutting tool stressed more even, can guarantee the steady running of hone rod end head, be conducive to improve the precision of piston hole hone.U-groove bevel is a kind of form of the utility model auxiliary hole, and auxiliary hole can also be just like other shapes such as circles.
As shown in Figure 4, Fig. 4 is the schematic representation after the fine finishing of the utility model cylinder block blank.The bottom surface of U-groove bevel 1-4 can be concave surface or plane.As can be seen from Figure 4, because the degree of depth of U-groove bevel 1-4 is greater than the diameter of piston hole 1-5, after processing piston hole 1-5 at the cylinder block blank, the upper extreme point b of U-groove bevel 1-4 bottom is positioned at the below of piston hole 1-5 bottom lower extreme point a, be that U-groove bevel 1-4 bottom is lower than piston hole 1-5 bottom, thereby can not touch with U-groove bevel 1-4 bottom connection when guaranteeing hone bar hone piston hole 1-5.Compare with the cylinder block blank of prior art, U-groove bevel and the piston hole amount of finish of existing cylinder block blank are larger, and one-sided U-groove bevel is when causing easily the hone piston hole, and hone rod end head deforms easily at the U-groove bevel place, thereby affects piston hole hone precision.Cylinder block blank of the present utility model directly casts out U-groove bevel, not only reduce cylinder block blank materials, also reduce simultaneously piston hole and U-groove bevel post-production amount, reach the purpose of saving cost, and the hone bar deforms can effectively avoid the hone piston hole time, improve the hone precision, be convenient to simultaneously wrist pin and install when mistake occurring and can take out smoothly.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
