Abstract
Description
Technical Field
[0001] This utility model relates to the field of pneumatic scissors technology, specifically to a pneumatic scissors for use in confined spaces. Background Technology
[0002] In modern industrial processing, wire winding is a crucial production step, and the precise cutting of wire has a key impact on product quality and production efficiency. Pneumatic shears, with their ease of operation and other advantages, have become one of the commonly used tools for cutting wire in wire winding.
[0003] Currently, most pneumatic shears on the market use a straight handle design. Straight handle pneumatic shears are characterized by their simple structure and ease of operation. In a relatively spacious working environment, operators can easily use them to cut wires, thus they are widely used in conventional production scenarios.
[0004] However, with the continuous development of industrial production and the increasing demand for precision, special working environments are often encountered in actual production. For example, the limitations of straight-handle pneumatic shears become apparent when cutting wire in confined assembly spaces. Due to the limitations of their straight-handle structure and operation method, straight-handle pneumatic shears cannot flexibly approach the workpiece to be cut in these narrow spaces, resulting in reduced production efficiency and affecting production progress.
[0005] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content
[0006] The purpose of this invention is to provide a pneumatic scissors for use in confined spaces.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A pneumatic scissor for use in confined spaces, comprising a scissor structure and a drive component;
[0009] The scissor structure includes:
[0010] The first shearing member includes a first handle and a first shearing part connected together;
[0011] The second shearing member includes a second handle and a second shearing part connected together;
[0012] A connector is provided, wherein the first shearing part and the second shearing part are rotatably disposed relative to each other via the connector;
[0013] The driving member acts on at least one of the first handle and the second handle;
[0014] The first handle portion and the first shearing portion are arranged at an angle;
[0015] The second handle and the second shearing part are arranged at an angle;
[0016] Pneumatic shears have a shearing function:
[0017] In the shearing state, the driving member causes at least one of the first handle and the second handle to move closer to the other, so that the first shearing part and the second shearing part cooperate to cut the object to be sheared.
[0018] In the above scheme, taking the first shearing member as an example, the second shearing member is described in the same way: In some embodiments, the first handle extends along the first direction, the first shearing part extends along the second direction, the first direction and the second direction are set at an angle, and the length of the first handle is at least close to the length of the first shearing part (see figure), which can be regarded as making the first handle longer, thereby making the driving member away from the narrow working area and increasing the shearing force.
[0019] Continuing with the example of the first shearing member, the second shearing member is described in the same way: In some embodiments, the first shearing member has a shearing surface, the peripheral area of the shearing surface is made of an alloy material (such as aluminum alloy), or the first shearing member as a whole is made of an alloy material.
[0020] The connector can be understood as a fulcrum shaft structure.
[0021] The first handle and the first shearing part are set at an angle (the first handle can be regarded as a curved handle), and the second handle and the second shearing part are set at an angle. Taking the first handle and the first shearing part as an example: the first handle and the first shearing part constitute the first shearing member. Since the first handle and the first shearing part are set at an angle, the first shearing member does not extend along a straight line, which makes the pneumatic scissors suitable for environments with narrow straight (horizontal) spaces.
[0022] In summary, the pneumatic shears of this application are suitable for narrow spaces, have a simple structure, low structural cost, and high stability when performing shearing operations.
[0023] In some embodiments, the driving element is a cylinder. The driving element acts on at least one of the first and second handles, which is a conventional configuration. For example, a connecting hole is machined at the end of the first handle, and the cylinder piston rod is fixed to the first handle by a pin or connecting rod, ensuring that the cylinder can directly push or pull the first handle to rotate around a predetermined fulcrum when it extends or retracts.
[0024] In some embodiments, the first handle is integrally formed with the first shearing part, and the second handle is integrally formed with the second shearing part, thereby improving the overall structural strength of the pneumatic scissors.
[0025] A further technical solution involves, in the non-shearing state of the pneumatic scissors, the first shearing part and the second shearing part are spaced apart in the thickness direction of the pneumatic scissors to avoid mutual friction between the first shearing part and the second shearing part, thus slowing down the wear rate of the structure and reducing the resistance encountered during shearing.
[0026] A further technical solution includes an elastic reset member, with its two ends acting on the first and second handle portions, respectively. When the driving component stops operating, the elastic reset member increases the distance between the first and second handle portions, preparing for subsequent shearing operations. In some stages, the elastic reset member replaces the driving component, reducing energy consumption.
[0027] In some embodiments, the elastic reset element is a compression spring.
[0028] In a further technical solution, one end of the elastic reset member acts on the end of the first handle near the first shearing portion, and the other end of the elastic reset member acts on the end of the second handle near the second shearing portion.
[0029] Since the elastic reset component is close to the connector, on the one hand, only a small deformation is needed to generate enough torque to drive the handle (referring to the first handle and the second handle) to reset, which is suitable for scenarios that require rapid opening of the shearing section (referring to the first shearing section and the second shearing section) (such as high-frequency shearing operations); on the other hand, it does not need to occupy the space at the end of the handle (the end away from the connector), which is suitable for compact design.
[0030] The two ends of the elastic reset member act on the opposite sides of the first handle and the second handle, respectively.
[0031] A further technical solution involves providing a fixing groove on both the first and second handle portions for accommodating the end of the elastic reset member. This fixing groove design enables a detachable connection between the elastic reset member and the handle structure, facilitating quick replacement of the elastic reset member as needed.
[0032] In a further technical solution, the end of the first shearing part away from the first handle has a first clearance slope, and the end of the second shearing part away from the second handle has a second clearance slope. The design of the clearance slopes makes this application more suitable for compact designs, thereby further improving the applicability of this application. The inclination angle of the clearance slopes is not limited here.
[0033] Taking the first avoidance ramp as an example, the setting of the first avoidance ramp is equivalent to reducing the size of the end of the first shearing part away from the first handle. Due to the size reduction at a specific position, the first shearing part can penetrate into narrow spaces during shearing operations.
[0034] In a further technical solution, the first shearing part has a first shearing surface, which is a straight surface;
[0035] The second shearing part has a second shearing surface, which is an inclined surface.
[0036] For ease of understanding, the following additional explanation is provided: The first shearing surface is a straight surface, and its width direction is parallel to the width direction of the pneumatic shears; the second shearing surface is an inclined surface, and its width direction is set at an angle to the width direction of the pneumatic shears.
[0037] The first shearing surface is a straight surface, which can be understood as the first shearing part having a straight cutting edge. During the shearing operation, the contact surface between the shearing part and the object to be sheared is large, which prevents the object to be sheared from slipping and ensures a flat cut.
[0038] The second shearing surface is an inclined plane, which can be understood as the second shearing part having an inclined cutting edge. During the shearing operation, the contact area between the shearing part and the object to be sheared is small, making it easier to cut the object to be sheared.
[0039] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence, nor are they intended to limit this case; they are merely used to distinguish components or operations described using the same technical terms.
[0040] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.
[0041] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.
[0042] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.
[0043] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.
[0044] The working principle and advantages of this utility model are as follows:
[0045] During the shearing operation, the driving component causes at least one of the first handle and the second handle to move closer to the other, so that the first shearing part and the second shearing part cooperate to cut the object to be sheared.
[0046] The first handle and the first shearing part are set at an angle, and the second handle and the second shearing part are set at an angle. Taking the first handle and the first shearing part as an example: the first handle and the first shearing part constitute the first shearing member. Since the first handle and the first shearing part are set at an angle, the first shearing member does not extend in a straight line, which makes the pneumatic scissors suitable for environments with narrow straight spaces.
[0047] In summary, the pneumatic shears of this application are suitable for confined spaces, allowing for flexible access to the workpiece to be sheared, thus ensuring production efficiency and schedule. Furthermore, the pneumatic shears of this application have a simple structure, low cost, and high stability during shearing operations. Attached Figure Description

[0053] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0054] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.
[0055] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.
[0056] See Figures 1-4A pneumatic scissor for use in confined spaces, comprising a scissor structure 1 and a drive component 2;
[0057] The scissor structure 1 includes:
[0058] The first shearing member 11 includes a first handle 111 and a first shearing part 112 connected together;
[0059] The second shearing member 12 includes a second handle 121 and a second shearing part 122 connected together;
[0060] Connector 3, the first shearing part 112 and the second shearing part 122 are rotatably disposed relative to each other through the connector 3;
[0061] The driving member 2 acts on at least one of the first handle 111 and the second handle 121;
[0062] The first handle 111 and the first shearing part 112 are arranged at an angle;
[0063] The second handle 121 and the second shearing part 122 are arranged at an angle;
[0064] Pneumatic shears have a shearing function:
[0065] In the shearing state, the driving member 2 causes at least one of the first handle 111 and the second handle 121 to move closer to the other, so that the first shearing part 112 and the second shearing part 122 cooperate to cut the object to be sheared.
[0066] Taking the first shearing member 11 as an example, the second shearing member 12 is described in the same way: In some embodiments, the first handle 111 extends along a first direction, and the first shearing part 112 extends along a second direction. The first direction and the second direction are set at an angle. The length of the first handle 111 is at least close to the length of the first shearing part 112 (see figure). This can be regarded as making the first handle 111 longer, thereby making the drive member 2 away from the narrow working area and increasing the shearing force.
[0067] Taking the first shearing member 11 as an example, the second shearing member 12 is described in the same way: In some embodiments, the first shearing member 11 has a shearing surface, the peripheral area of the shearing surface is made of an alloy material (such as aluminum alloy), or the first shearing member 11 as a whole is made of an alloy material.
[0068] Connector 3 can be understood as a fulcrum shaft structure, and can be a structure such as a cylindrical pin.
[0069] The first handle 111 and the first shearing part 112 are set at an angle (the first handle 111 can be regarded as a curved handle), and the second handle 121 and the second shearing part 122 are set at an angle. Taking the first handle 111 and the first shearing part 112 as an example: the first handle 111 and the first shearing part 112 constitute the first shearing member 11. Since the first handle 111 and the first shearing part 112 are set at an angle, the first shearing member 11 does not extend along a straight line, thereby making the pneumatic scissors suitable for environments with narrow straight (horizontal) spaces.
[0070] In summary, the pneumatic shears of this application are suitable for narrow spaces, have a simple structure, low structural cost, and high stability when performing shearing operations.
[0071] In some embodiments, the drive element 2 is a cylinder. The drive element 2 acts on at least one of the first handle 111 and the second handle 121, which is a conventional configuration. For example, a connecting hole is machined at the end of the first handle 111, and the cylinder piston rod is fixed to the first handle 111 by a pin or connecting rod, ensuring that the cylinder can directly push or pull the first handle 111 to rotate around a predetermined fulcrum when it extends or retracts.
[0072] In some embodiments, the first handle 111 is integrally formed with the first shearing part 112, and the second handle 121 is integrally formed with the second shearing part 122, thereby improving the overall structural strength of the pneumatic scissors.
[0073] Here, the first handle 111 and the first shearing part 112 are arranged at a first angle, and the second handle 121 and the second shearing part 122 are arranged at a second angle. The range and relationship of the first angle and the second angle are not limited, but preferably the first angle and the second angle are the same.
[0074] In this embodiment, in the non-shearing state of the pneumatic scissors, the first shearing part 112 and the second shearing part 122 are spaced apart in the thickness direction of the pneumatic scissors to avoid mutual friction between the first shearing part 112 and the second shearing part 122, thus slowing down the wear progress of the structure and reducing the resistance encountered during shearing.
[0075] See Figure 2 In this embodiment, an elastic reset member 4 is also included, with its two ends acting on the first handle portion 111 and the second handle portion 121, respectively. When the driving member 2 stops operating, the elastic reset member 4 increases the distance between the first handle portion 111 and the second handle portion 121, preparing for subsequent shearing operations. In some stages, the elastic reset member 4 replaces the driving member 2, reducing energy consumption.
[0076] In some embodiments, the elastic reset member 4 is a compression spring.
[0077] See Figure 2In this embodiment, one end of the elastic reset member 4 acts on the end of the first handle 111 near the end of the first shearing part 112, and the other end of the elastic reset member 4 acts on the end of the second handle 121 near the end of the second shearing part 122.
[0078] Since the elastic reset member 4 is close to the connector 3, on the one hand, only a small deformation is needed to generate enough torque to drive the handle (referring to the first handle 111 and the second handle 121) to reset, which is suitable for scenarios that require the shearing part (referring to the first shearing part 112 and the second shearing part 122) to open quickly (such as high-frequency shearing operations); on the other hand, it does not need to occupy the space at the end of the handle (the end away from the connector 3), which is suitable for a compact design.
[0079] The two ends of the elastic reset member 4 act on the opposite sides of the first handle 111 and the second handle 121, respectively.
[0080] See Figures 2-4 In this embodiment, both the first handle 111 and the second handle 121 are provided with fixing grooves 5 for accommodating the end of the elastic reset member 4. The design of the fixing grooves 5 enables a detachable connection between the elastic reset member 4 and the handle structure, facilitating quick replacement of the elastic reset member 4 as needed.
[0081] See Figures 2-4 In this embodiment, the end of the first shearing portion 112 away from the first handle portion 111 has a first clearance ramp 1121, and the end of the second shearing portion 122 away from the second handle portion 121 has a second clearance ramp 1221. The design of the clearance ramps makes this application more suitable for compact designs, thereby further improving the applicability of this application. The inclination angle of the clearance ramps is not limited here.
[0082] Taking the first clearance ramp 1121 as an example, the setting of the first clearance ramp 1121 is equivalent to reducing the end size of the first shearing part 112 away from the first handle 111. Since the size is reduced at a specific position, the first shearing part 112 can penetrate into narrow spaces during shearing operations.
[0083] See Figures 2-4 In this embodiment, the first shearing part 112 has a first shearing surface 1122, which is a straight surface;
[0084] The second shearing part 122 has a second shearing surface 1222, which is an inclined surface.
[0085] For ease of understanding, the following additional explanation is provided: the first shearing surface 1122 is a straight surface, and its width direction is parallel to the width direction of the pneumatic shears; the second shearing surface 1222 is an inclined surface, and its width direction is set at an angle to the width direction of the pneumatic shears.
[0086] The first shearing surface 1122 is a straight surface, which can be understood as the first shearing part 112 having a straight cutting edge. During the shearing operation, the contact surface between the shearing part and the object to be sheared is large, which prevents the object to be sheared from slipping and ensures a flat cut.
[0087] The second shearing surface 1222 is an inclined surface, which can be understood as the second shearing part 122 having an inclined cutting edge. During the shearing operation, the contact surface between it and the object to be sheared is small, making it easier to cut the object to be sheared.
[0088] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
