Description

Technical Field

[0001] This application relates to the field of welding technology, and more specifically, to a welding fixture and a massage device. Background Technology

[0002] In the guide rail manufacturing process, welding is a crucial step, directly affecting the guide rail's precision, stability, and durability. Precise fixing of the guide rail is a key step in ensuring welding quality and preventing misalignment. Traditional welding fixtures mostly rely on manual operation, using manually set fixed blocks as limiting devices to clamp and position the guide rail. This method is not only inefficient and easily affected by human factors (such as operator skill level and fatigue), but its limitations are particularly pronounced when facing mass production tasks, making it difficult to meet the demands of high-efficiency, high-precision production.

[0003] To improve welding efficiency and precision, some new welding equipment is adopting automated robots for rapid welding. This approach, through precise mechanical structures and programming, achieves efficient and automated operation, significantly reducing human intervention and improving welding accuracy and efficiency. However, the manufacturing and maintenance costs of automated robotic equipment are high, especially for small and medium-sized enterprises, where the investment is too expensive to be widely adopted. Furthermore, the complexity of this equipment places higher demands on the technical skills of operators, further increasing the difficulty of promotion. Utility Model Content

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. It should be noted that, unless otherwise specified, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application 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, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0036] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] One aspect of this application provides a welding fixture 1, such as... Figures 1 to 3 As shown, the fixture includes a base, a horizontal cylinder 11, a first positioning component, and a vertical cylinder 12. These components are arranged in a specific structure to achieve efficient clamping and fixation of the guide rail assembly 2. The base serves as the main support for the entire fixture, bearing and securely mounting all functional components, providing a fundamental guarantee for the stable operation of the fixture. The horizontal cylinder 11 and the vertical cylinder 12 respectively realize the driving functions in the horizontal and vertical directions, and through a clever connection relationship, together with the first positioning component, complete the precise positioning and secure clamping of the guide rail assembly 2.

[0038] The first positioning component includes a steering component and a horizontal moving member 131. The vertical cylinder 12 provides vertical driving force, which is converted into horizontal movement of the horizontal moving member 131 via the steering component. At the same time, the horizontal moving member 131 is positioned horizontally opposite to the horizontal cylinder 11, and the output end of the horizontal cylinder 11 also moves horizontally, cooperating with the horizontal moving member 131 to provide a stable clamping force, ensuring that the guide rail 21 of the guide rail assembly 2 is always in the predetermined position during the welding process, and preventing misalignment during welding.

[0039] In practical applications, when welding is required on the guide rail assembly 2, it is first placed on the base. Then, the vertical cylinder 12 is activated, its driving force transmitted to the horizontal moving member 131 via the steering component, causing the horizontal moving member 131 to move horizontally to pre-position the guide rail 21. Simultaneously, the horizontal cylinder 11 is activated, providing clamping force in another direction, which, together with the horizontal moving member 131, clamps the guide rail 21 of the guide rail assembly 2. Through this multi-directional cooperative clamping method, the guide rail 21 can be securely fixed at the welding station, thereby significantly improving welding accuracy and efficiency.

[0040] In summary, the welding fixture 1 provided in this application embodiment, by integrating a horizontal cylinder 11, a vertical cylinder 12, and a steering assembly, can achieve stable positioning of the guide rail assembly 2. Compared with traditional manual fixtures, it has a higher degree of automation, effectively reducing manual operation and improving welding efficiency and positioning accuracy. Furthermore, the combined design of the vertical cylinder 12 and the steering assembly gives the fixture strong adaptability to guide rail assemblies 2 of different sizes and specifications, further broadening its application range and demonstrating broad application prospects.

[0041] Optionally, such as Figure 2 and Figure 6 As shown, the steering assembly includes a sliding bracket 132 and a vertical sliding member 133. The sliding bracket 132 is mounted on a base. A vertical guide groove 132a and a horizontal guide groove 132b are designed on the sliding bracket 132 to provide motion constraints in the vertical and horizontal directions, respectively. The vertical sliding member 133 slides through the vertical guide groove 132a and is connected to the vertical output end 123 of the vertical cylinder 12, and can be driven to slide along the vertical guide groove 132a. The horizontal moving member 131 slides through the horizontal guide groove 132b and is linked with the vertical sliding member 133, enabling it to move in the horizontal direction.

[0042] Specifically, the vertical slider 133 is a key component connecting the vertical cylinder 12 and the horizontal moving part 131. One end of it is driven by the vertical cylinder 12, and the other end is movably connected to the horizontal moving part 131. The movement of the vertical slider 133 is constrained by the vertical guide groove 132a of the sliding bracket 132, ensuring a stable movement trajectory. Under the driving action of the vertical slider 133, the movement of the horizontal moving part 131 is constrained by the horizontal guide groove 132b, thus realizing the process of converting the driving force in the vertical direction into the movement in the horizontal direction. This structural design can utilize the precise movement control of the vertical slider 133 to ensure the smooth sliding of the horizontal moving part 131, providing a reliable guarantee for the precise positioning of the guide rail 21 during the welding process.

[0043] Optionally, such as Figure 3As shown, the first positioning component also includes a connector 134 connected to the horizontal moving member 131. An inclined groove 133a, relatively inclined to the horizontal direction, is provided on the vertical sliding member 133. Its main function is to convert the vertical movement of the vertical sliding member 133 into the horizontal movement of the horizontal moving member 131. The connector 134 is slidably connected within the inclined groove 133a. The vertical sliding member 133 is driven to slide along the vertical guide groove 132a, thereby driving the horizontal moving member 131 to slide along the horizontal guide groove 132b via the connector 134. The connector 134 can be in the form of a pin or similar structure. The vertical and horizontal air cylinders can be straight cylinders.

[0044] Specifically, such as Figures 3 to 7 As shown, the vertical output end 123 of the vertical cylinder 12 is fixed to the vertical sliding member 133 by screws. When gas enters through the air inlet 121 of the vertical cylinder 12, the vertical output end 123 of the vertical cylinder 12 extends upward in the vertical direction, driving the vertical sliding member 133 to slide upward along the vertical guide groove 132a. A guide hole 131b is provided on the horizontal moving member 131, and the connecting member 134 passes through the guide hole 131b. The size of the guide hole 131b matches the size of the connecting member 134. The upward movement of the vertical sliding member 133 causes the connecting member 134 in the inclined groove 133a to slide along the inclined path, pushing the horizontal moving member 131 to slide closer to the guide rail 21 in the horizontal guide groove 132b, thereby clamping one side of the guide rail 21. At the same time, the output end of the horizontal cylinder 11 extends horizontally to clamp the other side of the guide rail 21, achieving a firm double-sided clamping effect. This design cleverly converts the driving force of the vertical cylinder 12 into horizontal movement through the inclined slide 133a and the connecting member 134, thereby achieving stable clamping of the guide rail 21. After welding, when gas is discharged from the vent 122 of the vertical cylinder 12, the vertical output end 123 of the vertical cylinder 12 retracts, causing the vertical sliding member 133 to slide downward along the vertical guide groove 132a. The connecting member 134 in the inclined slide 133a then slides away from the guide rail 21, causing the horizontal moving member 131 to slide along the side of the horizontal guide groove 132b away from the guide rail 21. At the same time, the output end of the horizontal cylinder 11 retracts, releasing the other side of the guide rail 21 and releasing the clamping.

[0045] Optionally, such as Figure 5As shown, a horizontal groove 131a is provided on the horizontal moving member 131 to accommodate the sliding passage of the vertical sliding member 133. The design of the horizontal groove 131a not only makes full use of the structural space, but also increases the reliability of the connection between the horizontal moving member 131 and the vertical sliding member 133 through sliding fit. The width of the horizontal groove 131a in the horizontal direction is designed to be greater than or equal to the width of the inclined groove 133a on the vertical sliding member 133 in the horizontal direction. This matching of structural dimensions ensures that the connecting member 134 is not restricted by the horizontal groove 131a when sliding within the inclined groove 133a, thereby ensuring that the horizontal moving member 131's range of movement in the horizontal direction is not affected.

[0046] Optionally, such as Figure 2 and Figure 9 As shown, the welding fixture 1 also includes a horizontal clamp 16 mounted on the base and a third positioning component, both arranged horizontally opposite each other to clamp the end of the guide rail 21. The output end of the horizontal clamp 16 can move horizontally, and by cooperating with the third positioning component, it clamps the end of the guide rail 21, enhancing the fixing effect. It is worth noting that the design of the horizontal clamp 16 can be flexibly adjusted; for example, it can be replaced with a straight cylinder to adapt to different scenarios and needs.

[0047] Specifically, when the guide rail 21 is long, single-point fixing may lead to loosening or displacement in the middle or at the end. By setting the horizontal clamp 16 and the third positioning component to clamp the end of the guide rail 21 relative to each other, the fixing stability of the guide rail 21 can be improved. The horizontal clamp 16 applies a clamping force to one side of the guide rail 21 through the horizontal movement of its output end, while the third positioning component provides a counter-supporting force. The two are set opposite each other, forming a bidirectional clamp on the end of the guide rail 21, effectively limiting the horizontal displacement and rotation of the guide rail 21 during the welding process, ensuring that the guide rail 21 remains stable during welding. Based on this arrangement, the fixture can adapt to guide rails 21 of different lengths and specifications, meeting the needs of complex welding conditions.

[0048] In practical applications, when it is necessary to fix the end of the guide rail 21, the output end of the horizontal clamp 16 extends horizontally under the action of a horizontal driving force, cooperating with the third positioning component to clamp the end of the guide rail 21. After the output end of the horizontal clamp 16 contacts the guide rail 21, it provides sufficient clamping force to ensure the firmness of the end fixation. If the horizontal clamp 16 is replaced by a straight cylinder, the output end of the cylinder can also achieve horizontal movement through pneumatic drive, thereby completing the clamping action. When releasing the fixation, the output end of the horizontal clamp 16 or the output end of the straight cylinder retracts horizontally, releasing the guide rail 21 for convenient subsequent operations.

[0049] Optionally, such as Figure 2 and Figure 10As shown, the welding fixture 1 also includes a vertical clamp 17 and a fourth positioning component mounted on the base. The vertical clamp 17 and the fourth positioning component are arranged opposite each other in the vertical direction. The output end of the vertical clamp 17 moves in the vertical direction to cooperate with the fourth positioning component to clamp the guide rail 21. The design of the vertical clamp 17 can also be flexibly adjusted, for example, it can be replaced with a straight cylinder to adapt to different scenarios and needs.

[0050] Specifically, to further improve the positioning stability of the guide rail 21, the welding fixture 1 needs not only horizontal clamping capability but also vertical clamping capability to achieve reliable positioning in all directions. Specifically, the fixture includes a vertical clamp 17 mounted on a base and a fourth positioning component, both positioned opposite each other in the vertical direction. The output end of the vertical clamp 17 moves vertically, applying downward or upward clamping force to the guide rail 21, while the fourth positioning component provides a reverse supporting force. This ensures bidirectional clamping of the guide rail 21 in the vertical direction, applying clamping force to ensure the vertical stability of the guide rail 21 and effectively preventing displacement or tilting due to gravity or external forces. This design, in conjunction with the aforementioned clamping mechanism, forms a comprehensive multi-point positioning clamping system, further improving the welding accuracy and stability of the guide rail 21.

[0051] Optionally, such as Figure 2 and Figure 8 As shown, the welding fixture 1 also includes a corner cylinder 15 and a second positioning component mounted on the base. The corner cylinder 15 and the second positioning component are arranged opposite each other in the vertical direction. The output end of the corner cylinder 15 moves in the vertical direction to cooperate with the second positioning component to clamp the crossbeam 22 of the guide rail assembly 2.

[0052] Specifically, when the guide rail assembly 2 includes two or more parallel and spaced guide rails 21, in order to improve the stability of the overall structure, it is usually necessary to connect the multiple guide rails 21 into an integral frame through a crossbeam 22. In this case, simply positioning each guide rail 21 is insufficient; reliable positioning of the crossbeam 22 is also required to ensure the welding accuracy and overall stability of the frame. To address this need, the welding fixture 1 should also be designed with a dedicated clamping mechanism for positioning the crossbeam 22, including a corner cylinder 15 mounted on the base and a second positioning component. The output end of the corner cylinder 15 provides a downward clamping force to the crossbeam 22 through vertical movement, while the second positioning component provides support force on the opposite side. The two components are positioned opposite each other and work together to not only fix the crossbeam 22 but also further strengthen the constraint on the spacing between the guide rails 21 through the crossbeam 22, ensuring the geometric stability of the entire frame structure during the welding process. This design complements the guide rail 21 clamping mechanism, jointly achieving multi-point positioning of the guide rail assembly 2.

[0053] In practice, the corner cylinder 15 is mounted on the base, and its output end can extend or retract vertically. When it is necessary to fix the crossbeam 22, the output end of the corner cylinder 15 moves vertically under the action of air intake, cooperating with the second positioning component to clamp the crossbeam 22, thereby achieving the positioning of the crossbeam 22. The clamping position of the output end can be adjusted according to the thickness or shape of the crossbeam 22 to accommodate crossbeams 22 of different specifications. After welding is completed, the output end of the corner cylinder 15 retracts under the action of air exhaust, releasing the clamp on the crossbeam 22, facilitating subsequent operations.

[0054] It should be noted that when the guide rail assembly 2 has two guide rails 21, the design of the welding fixture 1 needs to simultaneously meet the requirements of stable positioning and clamping of both guide rails 21. Therefore, on the base, all clamping mechanisms are symmetrically arranged into two groups to accommodate the characteristics of the dual guide rails 21. Each group of clamping mechanisms acts on different positions of the corresponding guide rail 21, forming a symmetrical and uniform clamping force distribution, effectively preventing the guide rail assembly 2 from shifting position or deforming due to uneven force.

[0055] Optionally, such as Figure 2 and Figure 3 As shown, the base includes a first platform 141 and a second platform 142 arranged at intervals along the vertical direction. A horizontal cylinder 11 and a first positioning component are installed on the first platform 141, and a vertical cylinder 12 is installed on the second platform 142. The vertical output end 123 of the vertical cylinder 12 passes through the first platform 141 to be driven and connected to the first positioning component.

[0056] Specifically, the base structure of the welding fixture 1 can be designed in layers according to functional requirements, including a first platform 141 and a second platform 142 arranged at intervals along the vertical direction. The first platform 141 mainly houses the core clamping mechanism, including a horizontal cylinder 11, a first positioning component, a corner cylinder 15, a second positioning component, a vertical clamp 17, and a fourth positioning component. The second platform 142 houses the vertical cylinder 12, which is used to match and connect with the horizontal moving component 131 on the first platform 141 based on the height difference. The vertical output end 123 of the vertical cylinder 12 passes through the first platform 141 and is driven to connect with the horizontal moving component 131 on the first platform 141 through a vertical sliding component 133, forming a core motion mechanism that links vertical and horizontal movements. In addition, the installation positions of the horizontal clamp 16 and the third positioning component can be flexibly adjusted according to the type of guide rail 21. When the guide rail 21 is a straight guide rail 21, these components are mounted on the first platform 141; while when the guide rail 21 is an arc-shaped guide rail 21, due to the height difference between the ends and the middle position, the horizontal clamp 16 and the third positioning component can be mounted on the second platform 142. Through the layered design of the base, the welding fixture 1 can achieve full utilization of space and reasonable functional partitioning, ensuring that the connection between each clamping mechanism is tight and interference-free. At the same time, the layered design can effectively solve the problem of the height difference between the ends and the middle position of the arc-shaped guide rail 21, further improving the adaptability of the fixture.

[0057] In another aspect of the embodiments of this application, a massage device is provided, including a guide rail assembly 2 and a massage mechanism slidably mounted on the guide rail assembly 2. The guide rail assembly 2 is clamped in any of the above-mentioned welding fixtures 1 for welding operations, which can effectively improve welding efficiency and accuracy.

[0058] Optionally, the welding fixture 1 also includes a corner cylinder 15 and a second positioning assembly, such as Figure 11 As shown, the guide rail assembly 2 includes two guide rails 21 arranged parallel to both sides of the massage mechanism and a crossbeam 22 connecting the two guide rails 21. During the welding operation of the guide rail assembly 2, the guide rails 21 are clamped between the horizontal moving part 131 and the horizontal cylinder 11, and the crossbeam 22 is clamped between the corner cylinder 15 and the second positioning component, ensuring that the guide rail assembly 2 remains stable during the welding process.

[0059] Optionally, a rack is provided on the guide rail assembly 2, and a gear is provided on the massage mechanism. The gear meshes with the rack to form a mechanical transmission relationship. When the motor drives the gear to rotate, the rotational motion of the gear is converted into the linear sliding motion of the massage mechanism along the guide rail assembly 2 through meshing.
