Abstract
The utility model discloses a truck generator EGR shell, including left casing and right casing, left side casing and right casing joint, be equipped with inlet port and venthole on the casing of a left side, the outside extension of inlet port and venthole has the flange, its characterized in that the surface symmetry of left side casing and right casing is equipped with supports the groove, support the groove along left casing and the horizontal setting of right casing surface, it is provided with a plurality of ways to support the groove, and supports the groove along left casing and right casing evenly distributed from top to bottom. The support groove not only improves the intensity of shell as the strengthening rib, and the support groove that bilateral symmetry set up forms moreover puts the work or material rest, and the installation of the buckled plate of being convenient for can directly arrange left and right grooving in and form put the work or material rest.
Description
Technical Field
The utility model relates to an improvement invention of EGR shell, in particular to a truck engine EGR shell.
Background
The EGR shell is used for installation and protection of an EGR system, and the existing EGR shell of a truck has several problems: 1. the strength of the shell is insufficient, and the shell is easy to deform, so that internal elements are damaged; 2. the left shell and the right shell of the shell are connected insecure, and are separated; 3. the inner wall of the shell is smooth, so that the installation of the corrugated plate is not convenient.
SUMMERY OF THE UTILITY MODEL
In view of the technical problem who exists among the background art, the utility model aims at providing a truck engine EGR shell that shell intensity is high, non-deformable, impaired and more practical.
In order to solve the technical problem, the utility model discloses a following technical scheme: this truck generator EGR shell, including left casing and right casing, left side casing and right casing joint, be equipped with inlet port and venthole on the casing of a left side, the outside extension of inlet port and venthole has the flange, its characterized in that the surface symmetry of left side casing and right casing is equipped with supports the groove, support the groove along left casing and right casing surface level setting, support the groove and be provided with a plurality of ways, and support the groove along left casing and right casing evenly distributed from top to bottom.
The clamping position of right side casing and left casing is for inserting end and joint end respectively, the inner wall thickness that inserts the end is thinner than right casing, the joint end of left side casing outwards protrudes, just the joint end forms the slot with the terminal surface of left casing, the end of inserting of right side casing inserts in the slot, just insert the end and hold the tight fit with the joint.
And the clamping part of the left shell and the right shell is fixed by spot welding.
And the support grooves of the left shell and the right shell form material placing frames in the shells.
The supporting grooves arranged on the surfaces of the left shell and the right shell of the utility model not only serve as reinforcing ribs to improve the strength of the shell, but also form a material placing frame by the supporting grooves symmetrically arranged left and right, and the corrugated plate can be directly placed on the material placing frame formed by the left and right grooving, thereby facilitating the installation of the corrugated plate; additionally, the utility model discloses an adopt spot welding fixed behind left casing and the right casing joint, left and right casing not only simple to operate, firm in connection moreover.

Detailed Description
The following describes embodiments and examples of the present invention with reference to the accompanying drawings. The EGR shell of the truck generator comprises a left shell 1 and a right shell 4, wherein the left shell and the right shell are clamped, the clamping parts of the right shell and the left shell are an insertion end 3 and a clamping end 2 respectively, the inner wall thickness of the insertion end 3 is thinner than that of the right shell 4, the clamping end 2 of the left shell protrudes outwards, the clamping end 2 and the left shell 1 form a ladder shape as shown in the attached drawing 4, the clamping end and the end surface of the left shell form a slot 9, the insertion end 3 of the right shell is inserted into the slot 9, the insertion end 3 is tightly matched with the clamping end 2, the inner wall of the insertion end 3 is thinner, the extrusion is easier, the insertion end after being pressed enters the slot 9, the insertion end resets in the slot and is tightly attached to the inner wall of the clamping end 2, so that the left shell 1 and the right shell 4 are tightly clamped together, in order to further ensure that the left shell and the right shell are firmly connected, the clamping parts of the left shell, after the left shell and the right shell are clamped, the shells are connected in a spot welding mode, and firm connection of the shells is guaranteed.
The left shell is provided with an air inlet hole 6 and an air outlet hole 7, the air inlet hole and the air outlet hole extend outwards to form a flange 5, the flange is arranged to enable the air inlet pipe and the air outlet pipe to be sleeved outside the flange, and the air inlet pipe and the air outlet pipe are fixedly connected with the shell in a welding mode; the surface of the left shell 1 and the surface of the right shell 4 are symmetrically provided with supporting grooves 8, namely the supporting grooves on the left shell and the supporting grooves on the right shell are on the same horizontal plane, the supporting grooves 8 are horizontally arranged along the surfaces of the left shell 1 and the right shell 4, the supporting grooves 8 are provided with a plurality of channels, and the supporting grooves are uniformly distributed along the left shell and the right shell up and down, namely the distance between the upper and lower adjacent supporting grooves 8 is equal, the supporting grooves are arranged to enable the surfaces of the left shell and the right shell to form convex surfaces and concave surfaces which are arranged at intervals, and the strength is higher and not easy to deform relative to a planar shell, so that the arrangement of the supporting grooves is equivalent to the arrangement of reinforcing ribs on the shell, and the pressure resistance of the shell is; and the support groove of left side casing and right casing forms in the shell and puts the work or material rest, and the corrugated plate can directly be arranged in on the work or material rest of putting that left and right grooving formed promptly, the installation of the corrugated plate of being convenient for.
