Description

Technical Field

[0001] This utility model relates to the field of cylinder assembly technology, and more specifically, to a multi-model cylinder assembly structure. Background Technology

[0002] Currently available cylinder assembly structures are mostly custom-designed tooling tailored to the dimensions, interfaces, and performance parameters of specific cylinder models. While this specialized design can ensure good stability and fit when adapting to specific cylinders, it severely lacks versatility.

[0003] However, due to differences between manufacturers, or various factors affecting different batches from the same manufacturer, slight but not negligible differences may exist in their dimensions. For example, different manufacturers may use different casting tolerance control standards or processing methods, or even within the same manufacturer, changes in materials such as replacing cast iron with aluminum may alter the cylinder's external dimensions. If the assembly structure does not adequately consider and effectively accommodate these differences, it may lead to a series of problems during cylinder operation, such as unstable movement and seal failure, severely reducing the reliability and service life of the equipment.

[0004] In summary, how to achieve a multi-model cylinder assembly structure that can quickly and efficiently adapt to various cylinder models, successfully overcome the numerous installation difficulties caused by model differences, avoid frequent replacement of mounting seats or complex tooling adjustments, and ensure stable and reliable assembly and operation even when faced with inevitable minor dimensional variations in cylinders from different manufacturers and batches, has become a key technical problem that urgently needs to be solved in the current industrial production field. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model proposes a multi-model cylinder assembly structure.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] A multi-model cylinder assembly structure includes a base and a cylinder body. The upper end face of the base has an installation cavity for accommodating the cylinder body. Mounting plates are fixed on the left and right side walls of the cylinder body, and each mounting plate has a mounting hole. Guide rails are symmetrically arranged on both sides of the mounting cavity on the upper end face of the base, and the extension direction of the guide rails is perpendicular to the opening direction of the mounting cavity.

[0008] Each guide rail has a sliding block that slides within it. A mounting block is fixedly installed on the upper end face of the sliding block. The mounting block has a first threaded hole corresponding to the mounting hole. The guide rail also includes a first bolt that can pass through the mounting hole and be screwed into the first threaded hole. The base is also provided with a fixing device for locking the sliding position of the sliding block along the guide rail.

[0009] The cylinder body is placed in the mounting cavity on the upper end face of the base. By moving the slider, the first threaded hole on the mounting block is aligned with the mounting hole on the cylinder body mounting plate. After alignment, the first bolt is passed through the mounting hole on the cylinder body mounting plate and screwed into the first threaded hole on the mounting block, thereby fixing the cylinder body to the mounting block on the base. The fixing device on the base locks the sliding position of the slider along the guide rail after the cylinder body is initially fixed by the bolts, preventing the slider from shifting due to vibration or other reasons during cylinder operation, and ensuring the stability of the cylinder body's mounting position.

[0010] By sliding the guide rail and the slider, the position of the mounting block can be flexibly adjusted according to the mounting hole position of different cylinder models, thereby adapting to the mounting hole distance of different cylinders. This solves the problem of size differences between different cylinder models to a certain extent and improves the adaptability to various cylinder models.

[0011] Preferably, the guide rail has an inverted "T" shaped cross-section; the slider has an I-shaped cross-section that matches the guide rail, and the slider includes: a first horizontal plate embedded in the guide rail, a second horizontal plate located outside the guide rail, and a vertical guide plate that vertically connects the first horizontal plate and the second horizontal plate.

[0012] Because the guide rail has an inverted "T" shaped cross-section, the matching slider has an I-shaped cross-section, consisting of a first horizontal plate embedded in the guide rail, a second horizontal plate located outside the guide rail, and a vertical guide plate connecting the two. The first horizontal plate is embedded in the inverted "T" shaped guide rail, which makes the slider's sliding on the guide rail more stable. The vertical guide plate restricts the slider's horizontal offset, ensuring that the slider can only slide along the extension direction of the guide rail. This provides precise guidance for the mounting block and the connected cylinder body, ensuring accurate alignment of the mounting holes when adjusting the cylinder position.

[0013] Preferably, the fixing device includes a second bolt, and a second threaded hole is provided on the second horizontal plate. The second bolt can be screwed into the second threaded hole and pressed against the upper end surface of the base.

[0014] The second bolt in the fixing device matches the second threaded hole opened on the second horizontal plate. The operator rotates the second bolt to gradually screw it into the second threaded hole. As the second bolt is screwed in, its end gradually presses against the upper surface of the base. When the second bolt presses against the base, due to the friction, the slider's position on the guide rail is firmly locked, preventing it from sliding along the guide rail, thus ensuring the fixation of the mounting block connected to the slider and the cylinder body.

[0015] Preferably, each second horizontal plate has two second threaded holes, which are symmetrically arranged along the guide rail.

[0016] Two second threaded holes symmetrically arranged along the guide rail, in conjunction with the second bolts, can more evenly distribute the various forces generated during cylinder operation, avoiding uneven force distribution, torsion, or displacement of the slider that may occur due to single-point fixing. Compared to single-bolt fixing, this symmetrical fixing method greatly enhances the stability of the slider on the guide rail, further improving the reliability of the entire cylinder assembly structure, ensuring stable operation of the cylinder under complex working conditions, and reducing equipment failures caused by unstable fixing.

[0017] Preferably, a positioning shaft is provided at the center of the bottom wall of the mounting cavity, and a positioning hole is provided at the center of the bottom wall of the cylinder body, into which the positioning shaft can be inserted.

[0018] After the positioning shaft is inserted into the positioning hole, it restricts the horizontal displacement and rotation of the cylinder, providing additional support and positioning. During cylinder operation, especially under significant impact or vibration, the fit between the positioning shaft and the positioning hole effectively reduces cylinder sway and enhances the stability of the installation structure. This helps maintain the relative positional relationship between the cylinder and other components, further improving the reliability of equipment operation and extending the equipment's service life.

[0019] The axial positioning method of the positioning shaft and positioning hole provides better compatibility for cylinders of different models but with similar positioning structures. Even if the cylinders have certain differences in length, width, and height, as long as the dimensions of the positioning shaft and positioning hole match, rapid positioning and installation can be achieved. This further expands the adaptability of this multi-model cylinder assembly structure to different cylinder models and improves its versatility and flexibility.

[0020] Preferably, the positioning shaft has a rectangular cross-section, and the positioning hole has a corresponding rectangular cross-section.

[0021] The rectangular cross-section positioning shaft and positioning hole fit together, greatly improving the positioning accuracy and stability. The four sides of the rectangle constrain each other, which, compared to a circular cross-section which can only restrict radial movement, can prevent the cylinder from shifting and rotating on the horizontal plane in all directions, making the cylinder's position in the mounting cavity more precise and stable.

Detailed Implementation

[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0030] Example

[0031] like Figures 1-5 As shown, the multi-cylinder assembly structure in this embodiment mainly consists of a base 110 and a cylinder body 120. A mounting cavity is formed on the upper surface of the base 110 to accommodate the cylinder body 120. Mounting plates 140 are fixedly mounted on the left and right side walls of the cylinder body 120, and each mounting plate 140 has a mounting hole 1401.

[0032] On the upper surface of the base 110, guide rails 1101 are symmetrically arranged on both sides of the mounting cavity. The cross-section of the guide rails 1101 is an inverted "T" shape, and its extension direction is perpendicular to the opening direction of the mounting cavity. Sliding sliders 150 with an I-shaped cross-section are slidably fitted within each guide rail 1101. Each slider 150 consists of a first horizontal plate 1501 embedded within the guide rail 1101, a second horizontal plate 1502 located outside the guide rail 1101, and a vertical guide plate 1503 vertically connecting the two horizontal plates. Two second threaded holes 1504 are symmetrically arranged along the guide rail 1101 on the second horizontal plate 1502 of the slider 150. A mounting block 160 is fixedly mounted on the upper surface of the slider 150. The mounting block 160 has a first threaded hole 1601 corresponding to the mounting hole 1401 on the mounting plate 140 of the cylinder body 120.

[0033] Furthermore, a rectangular positioning shaft 190 is provided at the center of the bottom wall of the mounting cavity, and a corresponding rectangular positioning hole 1201 is provided at the center of the bottom wall of the cylinder body 120. The fixing device uses a second bolt 180, which can be screwed into the second threaded hole 1504 on the second horizontal plate 1502 and abuts against the upper end face of the base 110. Simultaneously, a first bolt 170 is also provided, which passes through the mounting hole 1401 of the mounting plate 140 of the cylinder body 120 and screws into the first threaded hole 1601 of the mounting block 160.

[0034] Its specific operating principle is as follows:

[0035] When installing the cylinder body 120, first align the rectangular positioning hole 1201 at the center of the bottom wall of the cylinder body 120 with the rectangular positioning shaft 190 at the center of the bottom wall of the mounting cavity and insert it. Due to the rectangular cross-section design of the positioning shaft 190 and the positioning hole 1201, the four sides constrain each other, which can restrict the displacement and rotation of the cylinder on the horizontal plane in all directions, so that the cylinder can quickly and accurately reach the initial installation position.

[0036] Based on the position of the mounting hole 1401 on the mounting plate 140 of the cylinder body 120, the slider 150 slides along the guide rail 1101. Since the guide rail 1101 is inverted "T" shaped, the slider 150 that matches it is I-shaped. The first horizontal plate 1501 is embedded in the guide rail 1101, and the vertical guide plate 1503 restricts the horizontal offset, so that the slider 150 can slide precisely along the guide rail 1101, driving the mounting block 160 to move, thereby aligning the first threaded hole 1601 on the mounting block 160 with the mounting hole 1401 on the mounting plate 140 of the cylinder body 120.

[0037] After aligning the mounting holes 1401, the first bolt 170 is passed through the mounting holes 1401 of the mounting plate 140 of the cylinder body 120 and screwed into the first threaded hole 1601 of the mounting block 160, thus initially fixing the cylinder body 120 to the mounting block 160 on the base 110. After the cylinder body 120 is initially fixed, the second bolt 180 is rotated and screwed into the second threaded hole 1504 on the second horizontal plate 1502. As the second bolt 180 is screwed in, its end gradually presses against the upper end face of the base 110, using friction to firmly lock the position of the slider 150 on the guide rail 1101, preventing the slider 150 from shifting due to vibration or other reasons during cylinder operation, and ensuring the stability of the cylinder body 120's installation position.

[0038] The aforementioned configuration, through the sliding engagement of the guide rail 1101 and the slider 150, allows for flexible adjustment of the mounting block 160 position to accommodate different cylinder models. This effectively solves the installation difficulties caused by the size differences between different cylinder models and improves the adaptability to various cylinder types. Furthermore, the design of the positioning shaft 190 and the positioning hole 1201 ensures rapid positioning and installation even if the cylinders differ in length, width, and height, provided the dimensions match. This further expands the compatibility range and enhances versatility and flexibility.

[0039] In summary, the above are merely preferred embodiments of this embodiment. All equivalent changes and modifications made in accordance with the scope of the patent application of this embodiment shall fall within the scope of the patent of this embodiment.
