Description

Technical Field

[0001] This application relates to the technical field of regenerative blowers, and in particular to a positioning and installation tool for the air inlet of a regenerative blower. Background Art

[0002] The regenerative blower is designed according to the regenerative principle. The blades passing through the air inlet suck in the air and apply centrifugal force to accelerate the air forward and outward; the regenerative principle means that the air is pressed back by the annular housing to the bottom of the next blade and is thrown out again, and some pressure is increased with each regeneration.

[0003] In the blower industry, the front cover plate of the air inlet is generally bolted to the housing. To ensure zero leakage in the regenerative blower, the bolt connection is changed to welding. However, during the welding process, the position of the welded parts is not easy to determine. Once welding deviation occurs, leakage will occur at the air inlet of the blower, directly affecting the normal operation of the regenerative blower. Utility Model Content

The positioning mechanism includes a tooling column, and the diameter of the tooling column is smaller than the inner diameter of the air inlet pipe. Three equally spaced rectangular grooves are provided on the outer wall of the tooling column, and a positioning component is slidably installed on the inner walls of the three rectangular grooves. An installation cavity is provided inside the tooling column, and three equally spaced rectangular openings are provided on the inner wall of the installation cavity. An L-shaped seat is slidably connected to the inner walls of the three rectangular openings, and a driving component for driving the L-shaped seat to move is provided on the inner wall of the installation cavity.

[0006] With the above structure, the positioning mechanism facilitates the fixing of the air inlet pipe, and thus facilitates the welding of the air inlet pipe to the blower housing. The positioning component facilitates the welding positioning of the air inlet pipe. The rectangular grooves facilitate the adjustment of the position of the positioning component. The driving component in the installation cavity facilitates directly driving the L-shaped seat to fix the air inlet pipe.

[0007] The driving component includes a screw rod rotatably connected to the inner wall of the installation cavity, and a tapered seat is screwed on the outer wall of the screw rod. Three equally spaced sliding grooves are provided on the outer wall of the tapered seat.

[0008] With the above structure, the rotation of the screw rod in the installation cavity facilitates directly driving the tapered seat to move. The three sliding grooves are equally spaced and circumferentially distributed on the outer wall of the tapered seat.

[0009] The inner walls of the three sliding grooves are all slidably connected to sliding seats, and the three sliding seats are respectively fixedly connected to the three L-shaped seats.

[0010] With the above structure, the L-shaped seat and the conical seat are conveniently connected through the setting of the sliding seat. When the conical seat moves, it is convenient to drive the L-shaped seat to slide.

[0011] One end of the tooling column is fixedly and rotatably connected with a rotating part, and one end of the transmission shaft of the rotating part is fixedly connected to the screw.

[0012] With the above structure, the screw is conveniently driven to rotate directly through the setting of the rotating part. When the screw rotates, the position of the conical seat is directly adjusted.

[0013] The positioning assembly includes a positioning ring slidably connected to the inner walls of three rectangular grooves, and three equally spaced mounting seats are fixedly connected to the outer wall of the positioning ring.

[0014] With the above structure, the positioning ring is conveniently slidably installed through the setting of the rectangular groove.

[0015] Connecting rods are fixedly connected to the outer walls of the bottoms of the three mounting seats, and a positioning column is fixedly connected to one end of each connecting rod. Three equally spaced screw holes are formed in the outer wall of the positioning ring, and locking bolts are screwed into the inner walls of the three screw holes.

[0016] With the above structure, the positioning ring is conveniently fixed through the setting of the locking bolts. The adjustable positioning ring is convenient for positioning and welding air inlet pipes of different specifications.

[0017] One end of the locking bolt is in contact with the inner wall of the rectangular groove, and two symmetrically arranged handles are fixedly connected to the outer wall of the top of the tooling column.

[0018] With the above structure, the locking bolt is pressed in the rectangular groove, so as to conveniently fix the positioning ring on the tooling column. The setting of the handle is convenient for taking the tooling column.

[0019] An air inlet for installing an air inlet pipe is provided on one outer wall of the fan housing, and three equally spaced circular rib grooves are provided on one outer wall of the fan housing. The specifications of the positioning column and the rib grooves match.

[0033] Referring to Figure 5 , the driving component includes a screw rod 18 rotatably connected to the inner wall of the installation cavity 17, and a tapered seat 20 is screwed on the outer wall of the screw rod 18. Three equally spaced sliding grooves 21 are provided on the outer wall of the tapered seat 20. By rotating the screw rod 18 in the installation cavity 17, it is convenient to directly drive the tapered seat 20 to move. The three sliding grooves 21 are circumferentially and equally spaced on the outer wall of the tapered seat 20.

[0034] Referring to Figure 5 , a sliding seat 19 is slidably connected to the inner walls of the three sliding grooves 21, and the three sliding seats 19 are respectively fixedly connected to the three L-shaped seats 16. The sliding seat 19 is provided to facilitate the connection between the L-shaped seat 16 and the tapered seat 20.
