Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pressing tools for agricultural machinery, specifically to a pressing tool for a long clamping plate on a reversible plow. Background Technology
[0002] The reversible plow is a type of agricultural machinery. It is equipped with a rotating arm bushing and a long clamping plate. Since the rotating arm bushing and the long clamping plate are interference fit, they are currently installed by manual hammering. This method can easily damage the parts, and the long clamping plate is prone to tilting after installation.
[0003] A patent publication number CN221468275U was found, entitled "A Reinforcing Structure for a Plow Beam Used in a Reversible Plow," which specifically discloses a reinforcing structure for a plow beam used in a reversible plow, including an inner reinforcing plate and a rotating arm bushing. The inner reinforcing plate is installed on the inner side of the front end of the two main beam clamping plates of the reversible plow. The inner reinforcing plate includes an upper reinforcing plate, a lower reinforcing plate, and a support plate located between the upper and lower reinforcing plates. The upper and lower reinforcing plates are tightly fitted to the two main beam clamping plates, and the support plate is fitted to the main beam. Rotating arm bushing mounting holes are provided on both the upper and lower reinforcing plates at the front end of the inner reinforcing plate. The rotating arm bushing is fixed inside the rotating arm bushing mounting holes and extends through the main beam clamping plates vertically.
[0004] Analysis of the above-mentioned publicly available materials shows that a long clamping plate needs to be installed at the location of the rotating arm bushing. During the installation of the long clamping plate, manual hammering is generally used, which is time-consuming, labor-intensive, and can easily damage the parts. Utility Model Content

[0021] like Figure 1-2 As shown: Example
[0022] A pressing fixture for a long clamping plate 3 on a reversible plow includes a reversible plow square tube 1, a rotating arm bushing 2 mounted on the reversible plow square tube 1, a long clamping plate 3 mounted on the outer side of the reversible plow square tube 1, a fixed shaft 5 passing through the rotating arm bushing 2, a pressing step 4 provided on the rotating arm bushing 2, and a hollow hydraulic cylinder 6 connected to the fixed shaft 5; a pressing sleeve, including a pressing sleeve A7 and a pressing sleeve B8; and a fixing member, including a nut connecting plate 9 provided at one end of the fixed shaft 5 and a fixed shaft connecting plate 10 provided at the other end of the fixed shaft 5.
[0023] In this embodiment, a rotating arm bushing 2 is installed on the reversible plow square tube 1. This structure is existing technology. In order to further enhance the strength of the reversible plow square tube 1, a long clamping plate 3 is added to the outside. Since the rotating arm bushing 2 is provided with a pressing step 4, in order to improve the strength, the long clamping plate 3 and the pressing step 4 need to be interference-fitted. By using the pressing method of the hollow hydraulic cylinder 6, the long clamping plate 3 can be installed on the rotating arm bushing 2 with uniform force. Example
[0024] The fixed shaft 5 is connected to the hollow oil cylinder 6 and moves under the action of the hollow oil cylinder 6.
[0025] Unlike the above embodiments, in this embodiment, the fixed shaft 5 moves under the action of the hollow oil cylinder 6 to achieve the purpose of press fitting. Example
[0026] The pressing step 4 and the long clamping plate 3 are interference-fitted, and the outer side of the long clamping plate 3 is in contact with the pressing sleeve.
[0027] Unlike the above embodiments, in this embodiment, the press-fit step 4 and the long clamping plate 3 adopt an interference fit, which can improve the strength after installation. Example
[0028] The press-fit sleeves A7 and B8 are located on both sides of the rotating arm bushing 2.
[0029] Unlike the above embodiments, in this embodiment, due to the use of a press-fitting method, press-fitting sleeves A7 and B8 are provided on both sides of the rotating arm bushing 2, and the long clamping plate 3 is press-fitted by the press-fitting sleeves. Example
[0030] One end of the fixed shaft 5 is threaded and connected to the nut connecting plate 9 via the thread, while the other end of the fixed shaft 5 is fixedly connected to the fixed shaft connecting plate 10.
[0031] Unlike the above embodiments, in this embodiment, in order to fix the press sleeve A7 and the press sleeve B8, a thread is provided at one end of the fixed shaft 5 and a nut connecting plate 9 is connected, which also facilitates disassembly and passing through the rotating arm bushing 2.
[0032] The working method (or working principle) of this utility model:
[0033] In operation, the nut connecting plate 9 and the press sleeve B8 are first removed. Then, the fixed shaft 5 is passed through the rotating arm bushing 2. Before this, the long clamping plate 3 is manually put onto the direct inner sleeve and is not engaged with the press step 4. After the fixed shaft 5 passes through the rotating arm bushing 2, the press sleeve B8 is put on. Then, the nut connecting plate 9 and the fixed shaft 5 are connected and fixed. At this time, after operating the hollow cylinder 6, the fixed shaft 5 begins to move and drives the press sleeve B8 to press the long clamping plate 3 and the press step 4 to form an interference fit.
[0034] In this utility model, unless otherwise explicitly specified and limited, for example, it can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components or an interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
