Abstract
The utility model discloses a differential type air cylinder body. The differential type air cylinder body consists of a first-stage air cylinder body (1) and a second-stage air cylinder body (2) which are coaxially connected, wherein the first-stage air cylinder body (1) and the second air cylinder body (2) are connected through a ring flange and fastening screws arranged on the ring flange; an axial through hole (1a) is formed in the first-stage air cylinder body (1) on the ring flange; an axial stepped hole (2a) is formed in the second-stage air cylinder body (2); the end head of the second-stage air cylinder body (2) extends to form a guide post (2b); and the guide post (2b) extends into the axial through hole (1a) of the first-stage air cylinder body (1) and is attached to the axial through hole (1a). Due to the adoption of a split and guide post structure, a casing model is simpler, the clamping is more convenient during machining, dimension precision and position precision are easier to ensure and the qualification rate of products is higher.
Description
Technical field
The utility model relates to the gas compressor technical field, specifically, relates to a kind of stage differential style cylinder block.
Background technique
Traditional stage differential style cylinder block is the integrated type casting, because the cylinder body length of stage differential style cylinder block is longer, about 1200mm, its casting pattern is complicated, manufacture difficulty is high usually; Dimensional accuracy, positional accuracy are difficult to guarantee that product rejection rate is high, has caused the wide variety of materials waste; The product design size is big, clamping inconvenience during machining.
The model utility content
It is high that the purpose of the utility model provides a kind of product percent of pass, and convenient mounting and clamping, the simple stage differential style cylinder block of casting pattern during machining to improve the up-to-standard rate of product, reduce the manufacture cost of product.
In order to achieve the above object; A kind of stage differential style cylinder block of the utility model; One-level cylinder block (1) and secondary cylinder body (2) by coaxial connection are formed; Said one-level cylinder block (1) and secondary cylinder body (2) connect through flange plate and the fastening screw trip bolt (3) that is arranged on the flange plate, are provided with axial hole (1a) in the above one-level cylinder block (1) of said flange plate, are provided with axial step hole (2a) in the secondary cylinder body (2); The termination of said secondary cylinder body (2) is extended with directional post (2b), and said directional post (2b) stretches in the axial hole (1a) of one-level cylinder block (1) and fits together with axial hole (1a).
The fastening screw trip bolt (3) that is arranged on the flange plate is at least 8 and one-tenth circumference uniform distribution, to guarantee one-level cylinder block and secondary cylinder sports association knot firmly.
This model utility is divided into one-level, secondary cylinder body through split-type structural with the stage differential style cylinder block, and two cylinder block reliably connect through flange plate, and directional post can guarantee two coaxial all the time connections of cylinder block.Beneficial effect: the stage differential style cylinder block is divided into two parts, has reduced part length, made casting pattern more simple, clamp more conveniently during machining, dimensional accuracy, positional accuracy be prone to guarantee that more product percent of pass is higher.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the right elevation of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Stage differential style cylinder block shown in Figure 1 is split-type structural, is made up of the one-level cylinder block 1 and the secondary cylinder body 2 of coaxial connection, and one-level cylinder block 1 is casting with secondary cylinder body 2.One-level cylinder block 1 is provided with flange plate with the end that secondary cylinder body 2 interconnects, and one-level cylinder block 1 is bound up through flange plate and the fastening screw trip bolt 3 that is arranged on the flange plate with secondary cylinder body 2.Be provided with axial hole 1a in the one-level cylinder block 1, be used to install piston, piston is divided into one-level active chamber and secondary work chamber with axial hole 1a; Also be provided with air flue 1b and water channel 1c on the one-level cylinder block 1.Be provided with axial step hole 2a in the secondary cylinder body 2, the left cavity of axial step hole 2a is a Seal cage, and right cavity is used for dress plug filler, also is provided with water channel 2b on the secondary cylinder body 2.The water channel 1c of one-level cylinder block 1 communicates with the water channel 2b of secondary cylinder body 2.The termination of secondary cylinder body 2 is extended with directional post 2b, and directional post 2b stretches in the axial hole 1a of one-level cylinder block 1 and fits together with axial hole 1a, to guarantee the axial installation precision of one-level cylinder block 1 and secondary cylinder body 2.
Like Fig. 2, as preferably, be arranged on fastening screw trip bolt 3 on the flange plate and be at least 8 and become circumference uniform distribution.
Claims (2)
1. stage differential style cylinder block; It is characterized in that: one-level cylinder block (1) and secondary cylinder body (2) by coaxial connection are formed; Said one-level cylinder block (1) and secondary cylinder body (2) connect through flange plate and the fastening screw trip bolt (3) that is arranged on the flange plate; Be provided with axial hole (1a) in the above one-level cylinder block (1) of said flange plate; Be provided with axial step hole (2a) in the secondary cylinder body (2), the termination of said secondary cylinder body (2) is extended with directional post (2b), and said directional post (2b) stretches in the axial hole (1a) of one-level cylinder block (1) and fits together with axial hole (1a).
2. according to the described stage differential style cylinder block of claim 1, it is characterized in that: the fastening screw trip bolt (3) that is arranged on the flange plate is at least 8 and one-tenth circumference uniform distribution.
