Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinder assembly tooling, and more particularly to a high-efficiency assembly tooling for a spring-return type double-tube steering oil cylinder. Background Art

[0002] Currently, in the existing technology, a spring-return double-tube steering cylinder is used as an example. When the spring is in a free state before the steering cylinder is assembled, the total height of the pre-installed steering cylinder is about 210mm. During the assembly process, the spring needs to be compressed by 40mm. However, the spring force when the spring reaches the maximum compression is calculated to be about 474N (about 47Kg). Faced with the effect of the spring force, a single person cannot manually complete the assembly of this type of cylinder. Market research has found that large-scale tooling is used on the existing market for batch assembly, while small and medium-sized enterprises use manual assembly as the main production method.

[0003] To this end, in order to address the problem that the above-mentioned method of compressing the spring is not only complicated and labor-intensive, but also requires two people to work together simultaneously and has low production efficiency, this solution proposes an efficient assembly tool for a spring-return double-tube steering cylinder.

[0029] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0030] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0032] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," "provided with," "provided on," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances. Example

[0033] See also Figure 1-3 , an efficient assembly tool for a spring-return double-tube steering cylinder, comprising a support plate 1, the bottom end of the support plate 1 is fixedly connected to a tool base 2, a connecting plate 1 3 is fixedly connected to the bottom side wall of the support plate 1, a steering cylinder 4 is provided on one side of the connecting plate 1 3, a connecting plate 2 5 is fixedly connected to the top side wall of the support plate 1, and a toggle clamp assembly 6 is installed on one side of the connecting plate 2 5.

[0034] During use of this solution, in order to change the current situation where springs are compressed solely by manual labor and the operator's work is difficult and labor-intensive, in this embodiment, the operator can first pre-assemble the steering cylinder 4, then place the pre-assembled steering cylinder 4 on the tooling base 2, and press the pressing platform 67 by pulling and pressing the toggle clamp assembly 6, thereby pressing the limit plate 44 of the steering cylinder 4 into place, and finally tighten the bolts to complete the assembly of the steering cylinder 4.

[0035] During this process, the operator presses down on the toggle clamp assembly 6 to ensure full contact between the press platform 67 and the steering cylinder 4. This process eliminates interference and ensures complete installation. The entire process is smooth and fully meets the needs of the job. Compared to traditional manual work, this eliminates the need for two people to work simultaneously, allowing only one person to complete the assembly independently. It also avoids the risk of mechanical injury caused by unstable spring pressure.

[0036] See also Figure 1-2 The toggle clamp assembly 6 includes two connecting plates 3 61 fixedly connected by bolts on one side of the connecting plate 2 5, a handle 62 is rotatably connected between the rear inner walls of the two connecting plates 3 61, a limiting sleeve 63 is fixedly connected between the front inner walls of the two connecting plates 3 61, a connecting shaft 64 is inserted between the inner walls of the limiting sleeve 63, a connecting rod 65 is rotatably connected between the end of the connecting shaft 64 and the handle 62, the front end of the connecting shaft 64 is fixedly connected to a connecting seat 66, and the other end of the connecting seat 66 is installed with a pressing platform 67.

[0037] More specifically, the pressing platform 67 includes a platform body 671 provided on the bottom side of the connecting seat 66, the side ends of the platform body 671 are fixedly connected with a pressing block 672, and a nut member 673 is installed on the top of the platform body 671, and the nut member 673 is threadedly connected to the connecting seat 66.

[0038] During use of this solution, when the operator needs to press-fit the steering cylinder 4, he rotates the handle 62 counterclockwise. Due to the deflection of the position of the handle 62, the connecting rod 65 connected to the surface of the handle 62 is synchronously moved to a new position, and one end of the connecting rod 65 is connected to the surface of the connecting shaft 64, and the connecting shaft 64 is inserted into the limiting sleeve 63. When one end of the connecting rod 65 is rotated and deflected, the other end pushes the connecting shaft 64 to move linearly, thereby driving the pressing platform 67 connected to the connecting seat 66 to press the limiting plate 44 above the steering cylinder 4 into place, and finally tightening the bolts to complete the assembly of the steering cylinder 4.

[0039] During the press-fitting process, the platform 67 has its platform body 671 located on the upper side of the top of the cylinder head 43 , the pressing blocks 672 on both sides are located on the surface of the limit plate 44 for supporting the press-fitting, and the nut member 673 is fixedly installed with the connecting seat 66 .

[0040] See also Figure 2 The outer end of the handle 62 is provided with a protective sleeve 68.

[0041] During use, the present invention increases the friction between the hand and the handle 62 by sleeve-fitting the protective cover 68 on the outside of the handle 62, thereby strengthening the grip and providing a certain degree of protection for the hand.

[0042] See also Figure 1 and Figure 3 The steering cylinder 4 includes a cylinder body 41 provided on the upper side of the tooling base 2, and two groups of mutually overlapping spring members 42 are sleeved between the inner walls of the cylinder body 41. A cylinder head 43 is provided on the upper side of the spring member 42, and a limit plate 44 is sleeved on the upper end of the cylinder head 43. The limit plate 44 and the upper end of the cylinder body 41 are both provided with mounting holes 45 arranged corresponding to each other.

[0043] During use of this solution, the steering cylinder 4 is pressed in such a way that two sets of overlapping spring parts 42 are placed inside the cylinder body 41, wherein the diameter of one spring part 42 is smaller than the diameter of the other spring part 42, and then the cylinder head 43 is placed above the spring part 42, and finally a limit plate 44 is sleeved above the two cylinder heads 43, and finally, the limit plate 44 is pressed onto the upper surface of the cylinder body 41 under the press fitting of the press platform 67 and fixed by bolts.

[0044] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
