Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to a feeding device used for providing parts for a turbocharger core assembly when it is assembled. Background Art

[0002] It is well known in the turbocharger core assembly production industry that the turbocharger core assembly is composed of a turbine end sealing ring, a compression end sealing ring, a fixed sleeve, a thrust bearing, a floating bearing, a shaft seal, and a variety of ring parts (or sleeve parts) of different shapes. Usually, these parts are placed on shelves or piled on workbenches. During assembly, the assemblers take and install them as needed. Since these parts are placed on shelves or piled on workbenches, and the assemblers take and install them as needed during assembly, not only is the production efficiency low, but it is also easy to miss or install them incorrectly, making it difficult to ensure product quality. Utility Model Content

[0003] The problem to be solved by the utility model is to overcome the above-mentioned shortcomings and provide a feeding device for assembling a turbocharger core assembly. The utility model can improve production efficiency and product quality.

[0004] The above-mentioned problems to be solved by the utility model are achieved by the following technical solutions:

[0005] The feeding device for assembling the core assembly of a turbocharger of the utility model comprises a workbench, and is characterized in that it also comprises a controller and a display screen. The workbench is provided with a gantry, and the workbench inside the gantry is provided with at least two material racks for placing irregular parts and a pushing mechanism for pushing ring parts (or sleeve parts). The material rack and the pushing mechanism are provided with a first sensor and a second sensor respectively, and the first and second sensors are connected to the controller through wires, and the controller is connected to the display screen through wires.

[0006] The pushing mechanism includes a cylinder and a sliding box. The sliding box is tubular with a rectangular cross section. A pushing block is arranged inside the sliding box and the two are in sliding cooperation. The second sensor is located at the upper end of the bracket at the front end of the sliding box. The outer end of the piston rod of the cylinder is connected to the rear end of the pushing block. A column is arranged on the sliding box, and the lower end of the column is connected to the top of the sliding box. A support block is arranged on the upper end of the column. The support block is rectangular and perpendicular to the column. The rear end of the support block is connected to the upper end of the column. The front end of the support block extends forward and is connected to a material rod, which is parallel to the column. A circular hole is arranged on the top plate of the sliding box. The center of the circular hole corresponds to the lower end of the material rod. The lower end of the material rod extends into the circular hole and does not exceed the lower side of the top plate of the sliding box. When working, the ring-type parts (or sleeve-type parts) are passed on the material rod, and a pressing sleeve is arranged on the material rod above the ring-type parts (or sleeve-type parts).

[0007] There is a step in the middle of the upper surface of the pushing block, which makes the thickness of its front part smaller than that of its rear part, and the ring-like part (or sleeve-like part) is located in front of the step.

[0008] The height of the step is not less than the thickness of the ring-type part (or sleeve-type part).

[0009] It can be seen from the above scheme that the feeding device for assembling the turbocharger core assembly of the utility model includes a workbench, a controller and a display screen. A gantry is provided on the workbench, and a material rack for placing irregular parts and a pushing mechanism for pushing ring parts (or sleeve parts) are provided on the workbench. A first sensor and a second sensor are respectively installed on the material rack and the pushing mechanism, and the first sensor and the second sensor are connected to the controller through a wire, and the controller is connected to the display screen through a wire. When assembling the turbocharger core assembly, various irregular parts required for a turbocharger core assembly are first placed in each material rack for placing irregular parts, and then the ring parts (or sleeve parts) such as the turbine end sealing ring, the pressure end sealing ring, the fixed sleeve, the thrust bearing, the floating bearing and the shaft seal required for the turbocharger core assembly are respectively stacked on the material rod of the pushing mechanism. Then the assembly is started. During the assembly process, the irregular-shaped parts are manually taken out from the material rack by the operator. The quantity information taken out is converted into an electrical signal by the first sensor and sent to the computer in the controller in real time. After the computer is calculated, it is converted into a digital signal and displayed on the display screen. The ring-type parts (or sleeve-type parts) such as the turbine end sealing ring, the pressure end sealing ring, the fixed sleeve, the thrust bearing, the floating bearing and the shaft seal are respectively dropped from the material rod to the push block and pushed out by the extension of the cylinder piston rod of the push mechanism, and then taken away by the operator. Among them, the number of ring-type parts (or sleeve-type parts) such as the turbine end sealing ring, the pressure end sealing ring, the fixed sleeve, the thrust bearing, the floating bearing and the shaft seal taken away is converted into an electrical signal by the second sensor and sent to the computer in the controller. After the computer is calculated, it is converted into a digital signal and displayed on the display screen. It can be seen that the number of parts taken away by the operator is displayed on the display screen in real time. Compared with the background technology, it not only improves the production efficiency, but also avoids the occurrence of missing or wrongly installed parts, and ensures product quality.

For the sake of simplicity, the controller is omitted in the figure. A gantry 2 is provided on the workbench 9, and ten material racks 1 for placing irregular parts are provided on the workbench 9 inside the gantry 2. The ten material racks 1 are stacked into two layers, with five on each layer. Four pushing mechanisms for pushing ring-type parts (or sleeve-type parts) such as turbine end sealing rings, pressure end sealing rings, fixed sleeves, thrust bearings, floating bearings and shaft seals are provided on the upper material rack 1. The first sensor and the second sensor 15 are respectively provided on the material rack 1 and the pushing mechanism, and the first sensor and the second sensor 15 are both connected to the controller through wires, and the controller is connected to the display screen 4 through wires.

[0013] The pushing mechanism includes a cylinder 13 and a sliding box 8. The sliding box 8 is tubular and has a rectangular cross section. A pushing block 12 is arranged inside the sliding box 8 and the two are in sliding fit. A bracket 10 is arranged at the front end of the sliding box 8, and the second sensor 15 is installed at the upper end of the bracket 10.
