Description

Technical Field

[0001] This utility model relates to the field of vacuum reducer technology, and in particular to a front end cover connecting device for a vacuum reducer. Background Technology

[0002] like Figure 1 As shown, the vacuum reducer of this embodiment can be used with stepper motors and servo motors. From its external appearance, the vacuum reducer includes a rear end cover, a reducer housing 1, and a front end cover 3. The reducer housing 1 is circular, and the front end cover 3 is a square plate. During assembly, the vacuum reducer is connected using screws. Because the reducer housing 1 and the front end cover 3 have different shapes and their outer edges do not overlap, aligning their threaded holes is difficult, making assembly time-consuming, especially when there are many connecting screws.

[0003] Therefore, there is an urgent need to propose a front cover connection device for a vacuum reducer that is simple in structure and has a reliable connection. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a front cover connecting device for a vacuum reducer. The technical solution adopted by this utility model is as follows:

[0005] A front cover connecting device for a vacuum reducer is disposed on the reducer housing and the front cover. The front end of the reducer housing has a lower end ring with a sealing ring groove. Several connecting posts are evenly spaced on the lower end ring. Several threaded holes are formed on the lower end ring between adjacent connecting posts. An outer end ring is disposed at the bottom of the front cover. Several tapered holes are evenly spaced on the front cover, with each tapered hole corresponding to a threaded hole. Several locking grooves are evenly spaced on the outer end ring, each locking groove corresponding to a connecting post. A U-shaped limiting edge is provided on one side of each locking groove, and each connecting post is fitted and limited within the U-shaped limiting edge. A tapered screw is disposed within each tapered hole and threaded hole. An internal hexagonal hole is formed at the upper part of the tapered screw. A sealing ring is disposed within the sealing ring groove.

[0006] Furthermore, the tapered hole is provided through the outer end ring.

[0007] Furthermore, an upper ring is provided at the front end of the reducer housing; the upper ring is pressed against the inner side of the outer ring; the upper ring is placed inside the lower ring.

[0008] Furthermore, a rolling bearing mounting groove is provided at the top center of the front end cover.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] (1) This utility model sets a connecting post, a locking groove and a U-shaped limiting edge, inserts the connecting post into the locking groove, and rotates the front end cover so that the connecting post is locked in the U-shaped limiting edge, so as to facilitate the positioning of the threaded hole and the tapered hole.

[0011] (2) By setting threaded holes, tapered screws and tapered holes, the tapered screws are inserted as they rotate, so that they squeeze the tapered holes in the center, which solves the problem of slight misalignment between the connecting column and the U-shaped limiter along the locking position, and further positions and connects the front cover installation to ensure the reliability of the positioning connection.

[0012] (3) This utility model achieves a reliable sealing connection by setting a sealing ring groove, a sealing ring, an upper ring and an outer ring.

[0013] In summary, this utility model has the advantages of simple structure, accurate and reliable positioning, and convenient connection, and has high practical and promotional value in the field of vacuum reducer technology. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of this utility model include, but are not limited to, the following embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0027] In the description of the embodiments in this application, unless otherwise stated, "multiple" means two or more. For example, multiple processing units means two or more processing units; multiple systems means two or more systems.

[0028] like Figures 2 to 6 As shown, this embodiment provides a front cover connecting device for a vacuum reducer, which is disposed on the reducer housing 1 and the front cover 3. A motor 2 is disposed at the rear end of the reducer housing 1. In addition, a rolling bearing mounting groove 35 is provided at the top center of the front cover 3.

[0029] The reducer housing 1 has a lower end ring 11 at its front end, with a sealing ring groove 12 formed thereon, and a sealing ring disposed within the sealing ring groove 12. Additionally, an upper end ring 15 is located at the front end of the reducer housing 1, positioned inside the lower end ring 11. To ensure a reliable sealing connection, the sealing ring is pressed against the lower part of the outer end ring 31, with the upper end ring 15 pressed against the inner side of the outer end ring 31.

[0030] In this embodiment, to facilitate rapid coarse positioning, several connecting posts 13 are evenly spaced on the lower ring 11, and an outer ring 31 is provided at the bottom of the front cover 3. Several locking grooves 33 are evenly spaced on the outer ring 31, and the locking grooves 33 are fitted and connected to the connecting posts 13 one by one. A U-shaped limiting edge 34 is provided on one side of the locking groove 33. The connecting post 13 is fitted and limited within the U-shaped limiting edge 34 to achieve coarse positioning, after which the tapered screw 4 can be inserted.

[0031] In this embodiment, to achieve precise positioning, several threaded holes 14 are provided on the lower ring 11 and positioned between adjacent connecting posts 13, and several tapered holes 32 are evenly spaced in a ring on the front end cover 3. The tapered holes 32 correspond one-to-one with the threaded holes 14. A tapered screw 4 is disposed within the tapered holes 32 and threaded holes 14, and an internal hexagonal hole is formed at the upper part of the tapered screw 4. The tapered holes 32 penetrate the outer ring 31. In this embodiment, when the lower end of the tapered screw 4 enters the threaded hole 14, the tapered screw 4 does not completely contact the inner wall of the tapered hole 32. As the tapered screw 4 is screwed in, the upper part of the tapered screw 4 contacts the inner wall of the tapered hole 32, thus precisely positioning the front end cover 3.

[0032] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any changes made based on the design principles of this utility model, or any non-creative changes made on this basis, shall fall within the scope of protection of this utility model.
