Description

Technical Field

[0001] The utility model relates to the technical field of impeller processing tooling, in particular to a ventilation equipment impeller processing and positioning device. Background Art

[0002] An impeller is a circular disc with blades. It is usually mounted on a rotating shaft in mechanical equipment and driven by a motor or other power source to push the flow of liquid or gas. Basic blocks are usually turned, milled, and other processes are used to complete the processing of the impeller shape. During the processing, tooling is a basic and necessary fixed component. Only when the workpiece is fixed can the stable processing be ensured.

[0003] Most of the existing impeller processing and positioning devices only have basic locking, clamping and fixing functions. Generally, after high-pressure locking and turning, milling and other processes, it is very easy for the bottom surface of the workpiece to be adsorbed due to high pressure or jammed due to friction. At the same time, due to the shape of the impeller, it is inconvenient to disassemble and remove the impeller after processing. Operators often need to use tools to remove it, which is inefficient.

[0004] In order to solve the above problems, we have made improvements and proposed a ventilation equipment impeller processing and positioning device. Utility Model Content

Top-release rods are fixedly welded at equal intervals on the top surface of the bracket plate, and the number of the top-release rods is equal to the number of the impeller top-release holes. The top of each top-release rod is slidably connected to the bottom end inside the impeller top-release hole.

[0024] Impeller ejection holes 8 are opened at equal intervals in the middle of the top surface of the positioning tooling table 4. The impeller ejection holes 8 are arranged around the locking bolts 7. Equally spaced ejection rods 9 are fixedly welded on the top surface of the bracket plate 5. The number of ejection rods 9 is equal to the number of impeller ejection holes 8. The top of each ejection rod 9 is slidably connected to the bottom end of the impeller ejection hole 8. Based on the above structure of the positioning tooling table 4, positioning tooling tables 4 of different sizes can be customized in combination with impellers of different specifications.

[0025] A transmission groove 10 is provided on the bottom surface of the lifting column 3 , and a fixed sleeve 12 is provided in the middle of the driving channel tube 11 .
