Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, specifically to a stainless steel impeller positioning device. Background Technology

[0002] An impeller is a general term for a disk and the rotating blades mounted on it. Impellers can be classified according to their shape and whether they are open or closed.

[0003] Impellers made of stainless steel are called stainless steel impellers. Stainless steel blanks are machined by a machine tool and positioned on the machine tool's fixture. For stainless steel blanks with holes, the blank is placed on a rod extending from the fixture seat, and a nut is screwed onto the threaded end of the rod. The nut holds the stainless steel blank in place.

[0004] However, each time the nut needs to be tightened, the worker needs to turn it by hand. The lever arm of the worker turning the nut by hand is small, and it is quite difficult to turn the nut.

[0005] In view of this, we propose a stainless steel impeller positioning device. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides two embodiments.

[0026] Example 1

[0027] Please see Figure 1 and Figure 2A stainless steel impeller positioning device includes a clamp base 100 and a nut 300. A rod 200 is fixedly mounted on the clamp base 100. A thread A201 is provided on the outer periphery of the end of the rod 200 facing away from the clamp base 100. The nut 300 is threadedly connected to the thread A201 on the rod 200. The nut 300 is used to hold the stainless steel impeller blank fitted onto the rod 200. An extension structure 400 is provided on the nut 300; the extension structure 400 includes an extension rod disposed on the outer periphery of the nut 300. When installing the stainless steel impeller blank, the nut 300 and the rod 200 are separate. The rod 200 is passed through a hole in the middle of the stainless steel impeller blank. The operator screws the nut 300 onto the thread A201 on the rod 200. The operator holds the extension rod as a rotating arm and rotates it, causing the nut 300 to rotate, thereby increasing the lever arm of the nut 300 until the nut 300 holds the stainless steel impeller blank.

[0028] The extension rod is a telescopic rod 401, which can be extended to increase the lever arm for rotating the nut 300.

[0029] This utility model, by setting a telescopic rod 401, has the advantage of increasing the lever arm of the nut 300 by rotating the telescopic rod 401, making it easier to rotate the nut 300. It solves the problem that each time the nut 300 needs to be turned by hand, the lever arm of the nut 300 is small and the rotation of the nut 300 is relatively laborious.

[0030] Example 2

[0031] Based on the technical content of Embodiment 1 above, another embodiment is proposed. Please refer to [link / reference]. Figures 2 to 4 A stainless steel impeller positioning device is disclosed. One end of the bushing of a telescopic rod 401 is fixedly fitted with an end plate 402. A stud 403 is fixedly fitted on the side of the end plate 402 opposite to the telescopic rod 401. The stud 403 is threadedly connected to a threaded hole B301 on the outer circumference of a nut 300. A threaded hole A202 is provided at the end of the insertion rod 200 opposite to the fixture seat 100, and the stud 403 is threadedly connected to the threaded hole A202. The telescopic rod 401 can be detached from either the threaded hole A202 or the threaded hole B301. When the nut 300 is rotated, the stud 403 is threadedly connected to the threaded hole B301, increasing the lever arm of rotating the nut 300. When the impeller is machined on a machine tool, the stud 403 is threadedly connected to the threaded hole A202, and the telescopic rod 401 and the insertion rod 200 are coaxial, allowing the telescopic rod 401 to be properly positioned and preventing it from being lost.

[0032] This utility model features a detachable telescopic rod 401, which is provided by stud 403, screw hole A202 and screw hole B301. The telescopic rod 401 can be installed according to different usage conditions, which is convenient for use.

[0033] One end of the guide shaft of the telescopic rod 401 is rotatably connected to a threaded sleeve 404 via a rotating shaft 405. The threaded sleeve 404 is threadedly connected to the threaded portion B4011 on the outer circumference of the other end of the bushing tube of the telescopic rod 401. When the telescopic rod 401 is shortened to its shortest position, the threaded portion B4011 on the outer circumference of the bushing tube of the telescopic rod 401 keeps the telescopic rod 401 stably in its shortest position without occupying too much space.

[0034] Working principle: When installing the stainless steel impeller blank, the nut 300 and the insert rod 200 are separate. The insert rod 200 is passed through the hole in the middle of the stainless steel impeller blank. The stud 403 is threadedly connected to the screw hole B301. The screw sleeve 404 is rotated so that the screw sleeve 404 is separated from the thread B4011 on the outer circumference of the bushing tube of the telescopic rod 401. The telescopic rod 401 is stretched. The worker screws the nut 300 onto the thread A201 on the insert rod 200. The worker holds the telescopic rod 401 as a rotating arm and rotates it, driving the nut 300 to rotate until the nut 300 abuts against the stainless steel impeller blank.

[0035] The stud 403 can be separated from the threaded hole B301, and the stud 403 can be threadedly connected to the threaded hole A202. The telescopic rod 401 can be shortened, and the threaded sleeve 404 can be threadedly connected to the thread B4011 on the outer circumference of the other end of the bushing tube of the telescopic rod 401. The machine tool processes the fixed stainless steel impeller blank.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
