Description

Technical Field

[0001] This utility model belongs to the field of steering gear bearing processing equipment, and in particular relates to a cutting device for steering gear bearing connecting sleeve. Background Technology

[0002] Steering gear bearings are precision mechanical components in automotive steering systems used to support the rotation of the steering shaft (or gear mechanism). In existing agricultural machinery, steering gear bearings mostly use V-groove bearings. The two inner rings of a V-groove bearing need to be connected by a connecting sleeve. The existing connecting sleeves are made of thin plates (steel plates) that have been cut, folded, and bent. In the existing folding process, the thin plates, which are rolled up, are conveyed to a crank press by a conveying mechanism. Then, the crank press drives the cutting blade to move up and down to cut the thin plates.

[0003] Although the above structure can complete the cutting work, the existing conveying mechanism is a roller conveyor, which will shift during the conveying process, resulting in a slanted edge during cutting, which in turn affects the cutting effect. Utility Model Content

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figures 1-6 As shown, this embodiment aims to solve the technical problem of easy skewing in the existing connecting sleeve cutting process. To this end, the steering gear bearing connecting sleeve cutting device provided in this embodiment includes a crank press 1 and a shearing blade 11 and a blade holder 2 disposed on the crank press 1. The steel strip is cut into strips by the alternation of the shearing blade 11 and the blade holder 2. The above structure is a common existing structure, therefore, it will not be described in detail in this embodiment.

[0023] Considering that the main problem of strip skewing is the offset that occurs during the conveying of the steel strip, in this embodiment, a strip skewing guide device is provided on the cutter holder 2. The strip skewing guide device includes guide seats 21 spaced apart on the cutter holder 2. The guide seats 21 are generally rectangular blocks that extend from the front end of the cutter holder 2 to the rear end of the cutter holder 2. Placement grooves 22 are provided on the guide seats 21 and the cutter holder 2, that is, part of the placement groove 22 is on the guide seats 21 and part is on the cutter holder 2. The two placement grooves 22 penetrate the opposite surfaces of the two guide seats 21, so that the steel strip can pass through smoothly.

[0024] Meanwhile, a horizontal guide mechanism 3 and two side constraint mechanisms 4 are provided in the placement groove 22. The horizontal guide mechanism 3 is used to achieve vertical constraint, and the two side constraint mechanisms 4 achieve horizontal constraint. Therefore, in this embodiment, the horizontal guide mechanism 3 includes a mounting base 31 and a guide roller 32 rotatably disposed in the mounting base 31. In this embodiment, the mounting base 31 includes a mounting base body, and a semi-circular groove for placing the guide roller 32 and the rotating shaft is provided on the mounting base body. A cover plate 33 is provided on the mounting base body, and a semi-circular groove for the other half of the rotating shaft and a hole for the guide roller 32 are provided on the cover plate 33. Applying machine oil to the rotating shaft to keep it lubricated can ensure the rotation of the guide roller 32.

[0025] In this embodiment, the steel strip needs to be clamped by the upper and lower guide rollers 32. Therefore, the horizontal guide mechanism 3 is respectively installed in the placement grooves 22 of the guide seat 21 and the cutter holder 2. The mounting seats 31 are arranged vertically within the placement grooves 22 of the guide seat 21 and the cutter holder 2, and the guide rollers 32 are spaced apart relative to each other. The gap between the two guide rollers 32 is used for the passage of the steel strip. Considering that the upper mounting seat 31 needs to be fixed, the fixing method can be direct bolt fixing. In this embodiment, the guide seat 21 is also provided with a guide groove 23. Guide protrusions 34 are provided on both sides of the mounting seat 31 within the guide seat 21, located on either side of the guide groove 23 and the mounting seat 31. The guide protrusions 34 are elongated, mainly for ease of installation.

[0026] The two-sided constraint mechanism 4 includes a constraint seat 41 disposed in the placement groove 22. The constraint seat 41 is C-shaped and contains a constraint roller 42, which is vertically and rotatably disposed within the constraint seat 41. The opening of the constraint seat 41 faces the steel strip, that is, towards the opposite surfaces of the two guide seats 21.

[0027] To further achieve constraint, in this embodiment, an annular groove 43 is provided in the middle of the constraint roller 42, and the annular groove 43 of the two constraint rollers 42 form a constraint on both sides of the steel strip.

[0028] To secure the mounting base 31 and the constraint seat 41, in this embodiment, a fixing block 5 is also provided within the placement groove 22. The fixing block 5 is rectangular in shape, with a fixing hole at the top of the guide seat 21 and a threaded hole at the bottom of the placement groove 22 that mates with the fixing hole. A through hole 51 is provided on the fixing block 5. The fixing hole, through hole 51, and threaded hole are coaxially arranged. The fixing block 5 is secured by bolts passing through the fixing hole and the threaded connection between the through hole 51 and the threaded hole. Thus, locking with a single long bolt ensures that the mounting base 31 and the constraint seat 41 remain stationary.

[0029] Considering that maintaining horizontal stability is paramount during shearing, the horizontal guide mechanism 3 is positioned close to the shearing blade 11. That is, the horizontal guide mechanism 3 is located at the innermost edge of the placement groove 22.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
