Abstract
The utility model is related to a kind of cylinder block and the attachment structure with cylinder cap, outer wall of cylinder block is provided with some axial projections, axial kerve and through hole is offered on projection, the reinforcement for cylinder body can be used, while be also screw when being connected with cylinder cap, fixed kerve can when producing tubular cylinder with cylinder body one-shot forming, without secondary drilling processing, manufacturing procedure is simplified, cylinder cap is connected with cylinder body using common self-tapping screw, and size is accurate, easy to assembly；Outer wall can greatly increase the intensity of cylinder body using fixed kerve, can further reduce casing wall thickness, realize the lightweight of product, with lightweight, intensity height, the characteristics of cost is low.
Description
Technical field
The utility model is related to a kind of structure of cylinder, specifically a kind of cylinder block and the attachment structure with cylinder cap.
Background technology
Cylinder is the conventional part of mechanical field, and current cylinder is typically made up of, and cylinder body is most cylinder body and cylinder cap
Using the structure of cylinder, cylinder cap and cylinder body and between mainly have two ways connection, one kind is by screw that cylinder cap is direct
It is fixed on cylinder body, the second way is to connect two ends cylinder cap by long bolt, the two ends of stationary housing is extruded by two ends,
First way needs to open screw in cylinder ends, therefore the wall thickness of cylinder body is thicker, thus causes cylinder heavier-weight, separately
External cylinder ends, which open screw, needs secondary operation, adds generation originally；The second way needs cylinder body to coordinate with two ends cylinder cap,
Need to use long bolt and nut, assemble cumbersome, while the cost of screw rod is higher.
Utility model content
The utility model purpose is to provide a kind of cylinder block and the attachment structure with cylinder cap, is provided with outer wall of cylinder block
Axial kerve and through hole is offered on some axial projections, projection, you can with the reinforcement for cylinder body, while being also and cylinder
Screw during lid connection, fixed kerve can when producing tubular cylinder with cylinder body one-shot forming, without secondary drilling processing, simplify
Manufacturing procedure, cylinder cap is connected using common self-tapping screw with cylinder body, and size is accurate, easy to assembly；Outer wall is drawn using fixed
Groove can greatly increase the intensity of cylinder body, can further reduce casing wall thickness, realize the lightweight of product, with lightweight, intensity
Height, the characteristics of cost is low.
Following technical scheme is used to achieve the above object：
A kind of cylinder block and the attachment structure with cylinder cap, including cylinder body and cylinder cap, it is characterised in that：In described cylinder body
Outer wall be provided with some axial projections, offer axial kerve on the outside of projection, described kerve includes being opened in
The opening on axial through hole and projection lateral wall on projection, the kerve of one axial direction of through hole and opening formation, described cylinder
Connecting portion is set on the position of lid correspondence through hole, self-tapping screw is connected in corresponding through hole through connecting portion.
Described cylinder body is to be provided with four projections on the outside of aluminium section bar, the cylinder body.
The width of described opening is less than the diameter of through hole.
Described A/F is more than 1/2nd of through-hole diameter and less than 2/3rds of through-hole diameter.
The utility model is provided with some axial projections, projection in outer wall of cylinder block and offers axial kerve, kerve
It is easy to aluminium section bar to process through hole on projection when processing, without secondary operation, the utility model projection plays reinforcement
The effect of muscle, intensity is high, casing wall is relatively thin heavy most light, relative to the structure that existing cylinder body needs secondary operation screw, technique letter
Change cost-effective；It is directly connected between cylinder cap and cylinder body by self tapping screw, easy to assembly, connection is reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is decomposition texture schematic diagram of the present utility model；
Fig. 3 is the utility model cylinder ends structural representation.
Embodiment
As Figure 1-3, a kind of cylinder block and the attachment structure with cylinder cap, including cylinder body 1 and cylinder cap 2, described cylinder
Body 1 is aluminium section bar, and the outer wall of described cylinder body 1 is provided with the projection 3 of four axial directions, axial direction is offered in the outside of projection 3
Kerve 5, described kerve 5 includes the opening 32 being opened on the axial through hole 31 and projection lateral wall on projection 3, described
Opening 32 width be less than through hole 31 diameter.The kerve 5 of one axial direction of through hole 31 and the formation of opening 32, described cylinder cap 2
Connecting portion 21 is set on the position of correspondence through hole, self-tapping screw 6 is connected in corresponding through hole 31 through connecting portion 21.
The utility model, which is provided with outer wall of cylinder block on the projection of four axial directions, projection, offers axial kerve, kerve
It is easy to aluminium section bar to process through hole on projection when processing, without secondary operation, the utility model projection plays reinforcement
The effect of muscle, cylinder strength is high, casing wall is relatively thin heavy most light, relative to the structure that existing cylinder body needs secondary operation screw, work
Skill simplifies cost-effective；It is directly connected between cylinder cap and cylinder body by self tapping screw, easy to assembly, connection is reliable.
