Description

Technical Field

[0001] This utility model relates to the field of cylinder technology, and in particular to a cylinder. Background Technology

[0002] In the woodworking industry, nailing and nail removal are core processes that directly affect the precision of wood processing and the quality of finished products. Traditional manual methods such as using pliers and hammering are labor-intensive and inefficient. Currently, the industry has widely adopted pneumatic actuators such as nail-driving cylinders and nail-removing cylinders to achieve mechanized operations. In existing technical solutions, nail-removing cylinders are usually bolted to the machine tool. Relying on the displacement adjustment function of the machine tool, they can achieve precise docking with the workpiece station, thereby efficiently completing the nail removal and nailing actions, improving process adaptability and work efficiency. After the nail-removing cylinder is installed on the machine tool, the bolts need to be loosened to adjust the verticality of the cylinder body relative to the machine tool.

[0003] In one technique, see Figure 7 The nail-removing cylinder includes a cylinder assembly 1' and a fastener 2'. The cylinder assembly 1' includes a first cylinder 11' and a second cylinder 12'. The first cylinder 11' is positioned above the second cylinder 12' and has a downwardly extending connecting portion 111'. The fastener 2' passes through the connecting portion 111' and connects to the machine tool. An operating space 3' is formed between the connecting portion 111' and the outer wall of the second cylinder 12'. The verticality of the cylinder assembly 1' relative to the machine tool can be adjusted through this operating space 3'. In actual operation, the relatively small operating space 3' makes verticality adjustment very inconvenient. In addition, the combined actions of the nail-removing cylinder, such as extension, clamping, etc., require the transmission of power source and control signals through multiple air pipes and signal lines. These multiple air pipes and signal lines need to be installed on the machine tool simultaneously with the nail-removing cylinder, further increasing the difficulty of operation. This means that in some installation scenarios, verticality adjustment can only be performed on one side of the nail-pulling cylinder. Operators not only face inconvenience in applying force due to space constraints, but also easily have their operational accuracy affected by obstructed vision, which greatly increases the difficulty of tightening fastener 2' and thus prolongs the working time for verticality adjustment.

[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0005] The purpose of this invention is to solve the problem of inconvenient adjustment of the verticality of the cylinder body in the prior art of nail-removing cylinders, and to propose a new type of cylinder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cylinder includes a cylinder body assembly and a plurality of fasteners. The cylinder body assembly has an operating space, the operating space including a first wall and a second wall, the first wall and the second wall being disposed opposite to each other. The first wall includes a first portion and a second portion, some of the fasteners passing through the first portion and some of the fasteners passing through the second portion. The extension direction of the fasteners is defined as a first direction. Along the first direction, the distance from the first portion to the second wall is L1, and the distance from the second portion to the second wall is L2, where L1 > L2.

[0007] Furthermore, the cylinder assembly includes a first cylinder and a second cylinder, which cooperate to form the operating space, with the first wall located in the first cylinder and the second wall located in the second cylinder.

[0008] Furthermore, the first cylinder and the second cylinder are arranged along the second direction, the first cylinder is provided with a connecting part extending into the second cylinder, and the operating space is formed between the connecting part and the second cylinder; the first wall is provided on the side of the connecting part facing the second cylinder.

[0009] Furthermore, the connecting portion is integrally formed with the first cylinder body.

[0010] Furthermore, a protective plate is connected to the end of the connecting part, and the protective plate is in clearance fit with the second cylinder along the second direction, and the protective plate can at least limit the maximum displacement of the second cylinder along the second direction.

[0011] Furthermore, the guard plate is provided with a connecting end and a guard arm. The guard plate is fixedly connected to the end of the connecting part through the connecting end, and the second cylinder body is provided with a limiting step that can cooperate with the guard arm for limiting.

[0012] Furthermore, the cylinder also includes a slider, and the fastener passes through the connecting portion and is installed onto the slider.

[0013] Furthermore, a stepped portion is formed at the connection between the first part and the second part, and the height of the stepped portion is not less than the thickness of the head of the fastener.

[0014] The beneficial effects of this utility model after adopting the above structure are as follows: The cylinder of this utility model, by designing that the distance between the first part and the second wall is greater than the distance between the second part and the second wall, effectively solves the problem of inconvenient operation of adjusting the verticality of the cylinder assembly in the prior art. Operators can conveniently tighten the fasteners installed in the first part and the fasteners installed in the second part from one side of the cylinder assembly. Specifically, when it is necessary to tighten the fasteners in the second part, the tool can be inserted into the operating space to the fasteners installed in the second part. Because L1 is greater than L2, the fasteners installed in the first part will not interfere with the tool when tightening the fasteners installed in the second part. In summary, with the help of the design that L1 is greater than L2, the fasteners installed in the second part, which were originally difficult to reach due to space limitations, can also be operated efficiently without additional adjustment of equipment position or disassembly of pipelines. This invention reduces the operational difficulty in adjusting the verticality of the cylinder assembly, shortens the time required for adjusting the verticality of the cylinder assembly, and reduces the risks of pipeline pulling and fastener damage caused by inconvenient operation, further improving the convenience and reliability of cylinder use.

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] In the description of this utility model, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] 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 technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, the term "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the 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.

[0022] In this utility model, unless otherwise explicitly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0023] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this invention are for illustrative purposes only and do not represent the only possible implementation.

[0024] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 6As shown, a cylinder includes a cylinder body assembly 1 and a plurality of fasteners 2. The cylinder body assembly 1 has an operating space 3, which includes a first wall 31 and a second wall 32, which are arranged opposite to each other. The first wall 31 includes a first portion 311 and a second portion 312. Some of the fasteners 2 pass through the first portion 311, and some of the fasteners 2 pass through the second portion 312. The extension direction of the fasteners 2 is defined as a first direction. Along the first direction, the distance from the first portion 311 to the second wall 32 is L1, and the distance from the second portion 312 to the second wall 32 is L2, where L1 > L2. The cylinder also includes a slider 5, and the fasteners 2 are installed on the slider 5 after passing through the connecting portion 111.

[0026] Based on the above embodiments, this utility model provides a cylinder that effectively solves the problem of inconvenient operation in adjusting the verticality of the cylinder assembly 1 in the prior art by designing that the distance between the first part 311 and the second wall 32 is greater than the distance between the second part 312 and the second wall 32. Operators can conveniently tighten the fasteners 2 installed on the first part 311 and the second part 312 from one side of the cylinder assembly 1. Specifically, when it is necessary to tighten the fasteners 2 of the second part 312, a tool can be inserted into the operating space 3 to the fasteners 2 installed on the second part 312. Because L1 is greater than L2, the fasteners 2 installed on the first part 311 will not interfere with the tool when tightening the fasteners 2 installed on the second part 312. In summary, by using the design that L1 is greater than L2, even the fasteners 2 installed on the second part 312, which were originally difficult to reach due to space constraints, can be operated efficiently without additional adjustment of the equipment position or disassembly of pipelines. This invention reduces the operational difficulty in adjusting the verticality of the cylinder assembly 1, shortens the time required to adjust the verticality of the cylinder assembly 1, and reduces the risks of pipeline pulling and fastener damage caused by inconvenient operation, further improving the convenience and reliability of cylinder use.

[0027] In some example installation scenarios, such as attached Figure 7As shown, the nail-removing cylinder includes a cylinder assembly 1' and a fastener 2'. The cylinder assembly 1' includes a first cylinder 11' and a second cylinder 12'. The first cylinder 11' is positioned above the second cylinder 12' and has a downwardly extending connecting portion 111'. The fastener 2' passes through the connecting portion 111' and connects to the machine tool. An operating space 3' is formed between the connecting portion 111' and the outer wall of the second cylinder 12'. Through this operating space 3', the fastener 2' can be loosened, thereby adjusting the verticality of the cylinder assembly 1' relative to the machine tool. In actual operation, because the operating space 3' is relatively small, adjusting the verticality of the cylinder assembly 1' is very inconvenient. In addition, the combined actions of the nail-removing cylinder, such as extension, extension, and clamping, require the transmission of power and control signals through multiple air pipes and signal lines. These multiple air pipes and signal lines need to be synchronously installed on the machine tool along with the nail-removing cylinder, further increasing the difficulty of operation. Specifically, in some example installation scenarios, the nail-removing cylinder is fixedly connected to the machine tool through the first outer side wall of the cylinder assembly 1'. Multiple air pipes are centrally installed on the second outer side wall opposite to the first outer side wall. Furthermore, the third outer side wall obstructs operation due to its proximity to the machine tool, resulting in the verticality adjustment of the cylinder assembly 1' only being possible through the fourth outer side wall. Moreover, when the operator performs the verticality adjustment of the cylinder assembly 1', the fastener 2' near the third outer side wall is difficult to apply force conveniently due to space constraints and obstructed view, which greatly increases the difficulty of tightening the fastener 2' and prolongs the working time for adjusting the verticality of the cylinder assembly 1'.

[0028] This utility model provides a cylinder that effectively solves the problem of inconvenient operation in adjusting the verticality of the cylinder assembly 1' in the above-mentioned technology by designing that the distance between the first part 311 and the second wall 32 is greater than the distance between the second part 312 and the second wall 32. This allows the operator to conveniently tighten the fasteners 2' near the third and fourth outer walls on the fourth outer wall side of the cylinder assembly 1'.

[0029] Specifically, when it is necessary to tighten the fastener 2 near the third outer side wall of the cylinder assembly 1, the tool can be inserted into the operating space 3 to the fastener 2 installed in the second part 312. Because L1 is greater than L2, when tightening the fastener 2 in the second part 312, the fastener 2 installed in the first part 311 will not interfere with the tool. The first direction is the insertion direction of the fastener 2, such as... Figure 5 As shown, the second direction is the height direction of the cylinder block assembly 1, as... Figure 4 As shown.

[0030] As another preferred embodiment of this utility model, a stepped portion 313 is formed at the connection between the first portion 311 and the second portion 312, and the height of the stepped portion 313 is not less than the thickness of the head of the fastener 2. In this embodiment, as... Figure 5 As shown, this structural design ensures that when operating the fastener 2 installed in the second part 312, the head of the fastener 2 installed in the first part 311 will not interfere with the tool, thus making the operation more convenient.

[0031] In another preferred embodiment of this utility model, the connecting portion 111 is integrally formed with the first cylinder body 11. In this embodiment, as... Figure 6 As shown, the integrated design eliminates the need for subsequent assembly steps and can directly use the first cylinder block 11's own reference surface as a unified machining reference. This completely avoids the cumulative errors caused by the gaps between parts and assembly positioning deviations in the split structure. Precision machining equipment can accurately control the perpendicularity accuracy of the connecting part 111 relative to the reference of the first cylinder block 11, and this accuracy will not shift due to loosening of assembled parts during long-term use. Its stability is significantly better than that of the split design. Secondly, the integrated molding makes the connecting part 111 and the first cylinder block 11 form a complete material whole. There are no weak connection parts 111 such as welded joints and bolted connections. This eliminates the risk of loose connections, stress concentration, or fatigue fracture after long-term use that may occur in the split structure. It can more reliably withstand the load, vibration and impact during the working process, and greatly improve the reliability and durability of long-term use.

[0032] In another preferred embodiment of this utility model, the cylinder assembly 1 includes a first cylinder 11 and a second cylinder 12, which cooperate to form the operating space 3. A first wall 31 is located in the first cylinder 11, and a second wall 32 is located in the second cylinder 12. The first cylinder 11 and the second cylinder 12 are arranged along a second direction. The first cylinder 11 is provided with a connecting portion 111 extending towards the second cylinder 12, and the operating space 3 is formed between the connecting portion 111 and the second cylinder 12. The first wall 31 is located on the side of the connecting portion 111 facing the second cylinder 12. In this embodiment, as... Figure 2 and Figure 4 As shown, during installation, the first cylinder 11 and the slider 5 are installed using fasteners 2, and then the second cylinder 12 is installed onto the first cylinder 11. After installation, the fasteners 2 are loosened through the operating space 3 to adjust the verticality of the cylinder assembly 1 relative to the machine tool.

[0033] As another preferred embodiment of this utility model, a protective plate 4 is connected to the end of the connecting part 111. Along the second direction, the protective plate 4 and the second cylinder body 12 are in clearance fit, and the protective plate 4 can at least limit the maximum displacement of the second cylinder body 12 along the second direction. The protective plate 4 is provided with a connecting end 41 and a guard arm 42. The protective plate 4 is fixedly connected to the end of the connecting part 111 through the connecting end 41, and the second cylinder body 12 is provided with a limiting step 121 that can be limited and fitted by the guard arm 42. In this embodiment, as... Figure 2 and Figure 4 As shown, the first cylinder 11 and the second cylinder 12 are connected by a long bolt 6. When it is necessary to adjust the installation position of the second cylinder 12 relative to the first cylinder 11, the long bolt 6 needs to be loosened. At this time, there is a risk that the second cylinder 12 will fall off the first cylinder 11. The guard plate 4 and the second cylinder 12 can cooperate with the limiting step 121 to prevent the second cylinder 12 from falling off the first cylinder 11 when the long bolt 6 is loosened. Specifically, when the long bolt 6 is loosened, the second cylinder 12 falls. When the second cylinder 12 falls to the limiting step 121 and the guard arm 42, the second cylinder 12 stops falling, avoiding damage to the second cylinder 12 caused by falling and personal injury. In this embodiment, along the second direction, the guard plate 4 and the second cylinder 12 are in a clearance fit to realize the adjustment of the second cylinder 12.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
