Description

Technical Field

[0001] The utility model relates to the technical field of turbochargers, and more specifically, to a fast-mounted turbocharger impeller. Background Art

[0002] A turbocharger is actually an air compressor that increases the intake volume by compressing air. It uses the inertial force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which presses the air sent from the air filter pipe to enter the cylinder with pressure. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, and the impeller compresses more air into the cylinder. The increase in air pressure and density can burn more fuel. By increasing the amount of fuel and adjusting the engine speed accordingly, the engine output power can be increased.

[0003] The utility model patent with patent announcement number CN214998429U discloses an impeller of a turbocharger, including two impellers, wherein the impeller includes a reinforcement plate, a support plate and a plurality of blades, wherein the reinforcement plate and the blades are respectively located on both sides of the support plate, and the blades are evenly distributed around the circumference of the support plate. The setting of the utility model is convenient for providing a new impeller for the turbocharger, so that the blades can be quickly disassembled and assembled as needed, and the existing integrated impeller can be changed to prevent the entire impeller from being unusable due to damage to a certain blade, thereby avoiding waste of resources. The utility model solves the problem that the impellers of existing turbochargers are mostly integrated structures, and when a certain blade is damaged, it cannot be replaced, resulting in the abandonment of the entire impeller and waste of resources.

[0004] However, when this structure is actually used, if one blade is damaged, it can avoid waste of resources. However, when multiple blades are damaged, they need to be replaced one by one, which reduces the replacement speed. Therefore, a quick-install turbocharger impeller is now proposed. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a quick-install turbocharger impeller to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick-install turbocharger impeller, including a vortex rod, a fixing plate is provided at one end of the vortex rod, a connecting rod is coaxially provided on one side of the fixing plate, a connecting plate is sleeved on the connecting rod, a plurality of bolts are connected between the connecting plate and the fixing plate, an impeller assembly is provided on one side of the connecting plate, a matching sleeve is provided on one side of the impeller assembly, and a locking pin for squeezing the matching sleeve is screwed on the end of the connecting rod.

[0007] Preferably, the connecting rod is a square structure, a square shaft hole is provided in the middle of the connecting plate, and limiting grooves and through holes are circumferentially provided on the connecting plate.

[0008] Preferably, the impeller assembly includes a fixing sleeve, blades, a limit block and a protrusion, a plurality of blades are fixedly arranged on the fixing sleeve, a limit block is arranged on one side of each blade, each limit block is respectively plugged into and matched with a corresponding limit groove, and a protrusion is coaxially arranged on the fixing sleeve.

[0009] Preferably, a first clamping hole is opened at one end of the matching sleeve, and a second clamping hole is opened at the other end of the matching sleeve. The first clamping hole is connected to the second clamping hole and both have a square structure. The first clamping hole is slidably matched with the protrusion, and the second clamping hole is slidably matched with the connecting rod.

[0010] Preferably, when the matching sleeve is sleeved on the protrusion to press the fixing sleeve, the end of the matching sleeve protrudes from the end of the connecting rod.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The fixing sleeve is connected to the connecting rod, and the limit blocks on one side of each blade are respectively inserted into the corresponding limit grooves. The limit blocks are limited by the limit grooves, thereby improving the support strength of the blades and thus improving the service life of the blades;

[0013] 2. The first clamping hole is sleeved on the protrusion, and the second clamping hole is slidably matched with the connecting rod, so that the connecting rod and the matching sleeve can rotate synchronously, thereby making the protrusion also rotate synchronously. The setting of the matching sleeve increases the connection length between the impeller assembly and the connecting rod, thereby further improving the force-bearing capacity of the impeller assembly, thereby ensuring that the impeller assembly can stably rotate synchronously with the connecting rod.

[0014] 3. When connecting with the connecting rod through the locking pin, during the locking process, the matching sleeve can be squeezed first, so as to ensure the extrusion strength of the matching sleeve on the impeller assembly, thereby improving the fixation of the impeller assembly. When replacing the impeller assembly, the locking pin can be directly removed, and the disassembly and assembly are convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS
