Description

Technical Field

[0001] This utility model relates to the field of pull rod assembly technology, and in particular to a gantry assembly device for a pull rod assembly of a pull rod case. Background Technology

[0002] Rolling suitcases are indispensable companions for modern travel, integrating a pull rod assembly and wheels to greatly facilitate travel. The pull rod assembly is the core functional component of a rolling suitcase, including the pull rod, roll cage, top bar, and handle, and its design directly affects the convenience and durability of the suitcase. During the assembly of the rolling suitcase pull rod assembly, the roll cage needs to be attached to the pull rod; therefore, we urgently need a roll cage assembly device for rolling suitcase pull rod assemblies.

[0003] Currently, the method for assembling the gantry crane onto the tie rod is manual, which involves manually picking up the gantry crane and assembling it onto the tie rod. However, this manual method requires aligning the gantry crane with the tie rod each time before assembly, which makes it difficult to align the gantry crane with the tie rod, is time-consuming and labor-intensive, and affects the assembly efficiency of the gantry crane. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the problem of low assembly efficiency of existing manual assembly of gantry frames, this utility model provides a gantry frame assembly device for a trolley case pull rod assembly. By improving the structure of the gantry frame assembly device for the trolley case pull rod assembly, the gantry frame can be automatically assembled onto the pull rod, thereby improving the assembly efficiency of the gantry frame.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a gantry assembly device for a trolley case pull rod assembly, comprising: a first fixing part, a driving mechanism, a second fixing part, and a guide rod. The first fixing part is used to support the pull rod. The second fixing part and the guide rod are both installed on the driving end of the driving mechanism. The second fixing part is used to support the gantry frame. The guide rod is used to guide the gantry frame assembly. The driving mechanism is used to drive the second fixing part and the guide rod to move towards or away from the first fixing part to assemble the gantry frame onto the pull rod.

[0006] Therefore, by driving the second fixed part to move closer to the first fixed part through the drive mechanism, the gantry frame is automatically assembled. Compared with the existing manual assembly method, this method has a simple structure and is easy to operate. The drive mechanism enables the gantry frame to be automatically assembled, thereby improving the assembly efficiency of the gantry frame. In addition, before the gantry frame is assembled, the guide rod is inserted into the tie rod. The guide rod plays a guiding role in the moving assembly process of the gantry frame to ensure that the gantry frame will not deviate during the assembly process and can be accurately inserted into the tie rod. This avoids damage to the gantry frame and tie rod due to misalignment of the gantry frame with the tie rod, thereby improving the accuracy of the gantry frame assembly.

[0007] As a further improvement to the above technical solution: the second fixing part includes a fixing seat, a first driving member, and a clamping block. The driving end of the driving mechanism is connected to the fixing seat. The fixing seat is used to support the gantry frame. The first driving member is mounted on the fixing seat. The clamping block is connected to the driving end of the first driving member. The first driving member is used to drive the clamping block to move towards or away from the fixing seat and to rotate around the axis of the driving end of the first driving member. The clamping block is used to clamp the gantry frame inside the fixing seat. Thus, the clamping block can clamp the gantry frame to ensure that the installed gantry frame remains stable and does not shift, allowing for precise insertion into the tie rod. This avoids damage to the gantry frame and tie rod due to misalignment during assembly, thereby improving the accuracy of gantry frame assembly.

[0008] As a further improvement to the above technical solution: two first driving components are provided, and the two first driving components are arranged opposite to each other; the number of clamping blocks is equal to the number of first driving components. Therefore, through the cooperation of the two first driving components and the two clamping blocks, the gantry can be clamped from both sides to ensure the stability of the gantry.

[0009] As a further improvement to the above technical solution, two guide rods are provided. Thus, the two guide rods cooperate with the two tie rods to achieve precise installation of the gantry frame.

[0010] As a further improvement to the above technical solution: the driving mechanism includes a second driving member and a third driving member. The second driving member and the third driving member are connected by a fixing block. The driving end of the second driving member is connected to the second fixing part. The second driving member is used to drive the second fixing part to move closer to or further away from the first fixing part. The driving end of the third driving member is connected to the guide rod through a push plate. The third driving member is used to drive the guide rod to move closer to or further away from the first fixing part. Thus, the second driving member can drive the gantry frame to move, thereby realizing the assembly operation of the gantry frame; the third driving member can drive the guide rod to move, thereby inserting the guide rod into the pull rod.

[0011] As a further improvement to the above technical solution: the guide rod is adapted to the gantry frame and the tie rod. Therefore, the guide rod is adapted to the gantry frame and the tie rod to ensure that the guide rod smoothly passes through the gantry frame and is inserted into the tie rod.

[0012] As a further improvement to the above technical solution, it also includes a driving unit, the driving end of which is connected to the driving mechanism. The driving unit is used to drive the driving mechanism to move along the Z-axis. Thus, by driving the driving mechanism, the second fixing part, and the guide rod to move along the Z-axis, it is ensured that the driving mechanism, the second fixing part, and the guide rod will not interfere with the movement of the first fixing part, thereby not affecting the assembly operation of the entire tie rod assembly.

[0013] As a further improvement to the above technical solution, it also includes: a workbench, the drive unit being connected to the workbench, the workbench having a storage box and a gripping robot, the storage box being used to store the gantry frame, and the gripping robot being used to grip the gantry frame stored in the storage box into the second fixing part.

[0014] As a further improvement to the above technical solution, it also includes: a conveying unit, wherein the first fixing part is connected to the conveying unit, and the conveying unit is used to drive the first fixing part to move along the Y-axis direction. Thus, by driving the first fixing part to move along the Y-axis direction through the conveying unit, the tie rod is conveyed to the gantry assembly position.

[0015] As a further improvement to the above technical solution, it also includes a base plate, to which both the worktable and the conveying unit are connected.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a drive mechanism to move the second fixed part closer to the first fixed part, thereby achieving automatic assembly of the gantry frame. Compared with the existing manual assembly method, this method has a simple structure and is easy to operate. The drive mechanism enables automatic assembly of the gantry frame, thereby improving the assembly efficiency. In addition, before assembling the gantry frame, the guide rod is inserted into the tie rod. The guide rod plays a guiding role during the moving assembly of the gantry frame, ensuring that the gantry frame will not deviate during the assembly process and can be accurately inserted into the tie rod. This avoids damage to the gantry frame and tie rod due to misalignment of the gantry frame with the tie rod, thereby improving the accuracy of the gantry frame assembly.

[0017] 2. This utility model uses a clamping block to clamp the gantry frame, ensuring that the installed gantry frame remains stable and does not shift. It can be accurately inserted into the tie rod, avoiding damage to the gantry frame and tie rod caused by misalignment during assembly, thereby improving the accuracy of gantry frame assembly.

[0018] 3. This utility model can drive the gantry frame to move through the second driving component to realize the assembly operation of the gantry frame; and can drive the guide rod to move through the third driving component to insert the guide rod into the tie rod.

[0019] 4. This utility model drives the drive mechanism, the second fixing part, and the guide rod to move along the Z-axis direction through the drive part, so as to ensure that the drive mechanism, the second fixing part, and the guide rod will not interfere with the movement of the first fixing part, thereby not affecting the assembly operation of the entire tie rod assembly.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, 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, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 utility model based on the specific circumstances.

[0026] like Figures 1 to 8 The diagram shows the preferred embodiment of this utility model. The gantry assembly device for the gantry assembly of the gantry box includes: a first fixing part 1, a driving mechanism 2, a second fixing part 3, and a guide rod 4. The first fixing part 1 is used to support the gantry. The second fixing part 3 and the guide rod 4 are both installed on the driving end of the driving mechanism 2. The second fixing part 3 is used to support the gantry, and the guide rod 4 is used to guide the gantry assembly. The driving mechanism 2 is used to drive the second fixing part 3 and the guide rod 4 to move towards or away from the first fixing part 1 to assemble the gantry onto the gantry. Therefore, the second fixed part 3 is driven by the drive mechanism 2 to move closer to the first fixed part 1, so as to realize the automatic assembly of the gantry (that is, to assemble the gantry onto the tie rod). Compared with the existing manual assembly method, this method has a simple structure and is easy to operate. The automatic assembly of the gantry can be realized by using the drive mechanism 2, thereby improving the assembly efficiency of the gantry. In addition, before the gantry is assembled, the guide rod 4 is inserted into the tie rod. The guide rod 4 plays a guiding role in the moving assembly process of the gantry, so as to ensure that the gantry will not deviate during the assembly process and can be accurately inserted into the tie rod. This avoids damage to the gantry and tie rod caused by the gantry not being aligned with the tie rod during the assembly operation, thereby improving the accuracy of the gantry assembly.

[0027] In other words, during the assembly of the gantry crane, it is necessary to align the gantry crane with the tie rod so that the gantry crane can be directly assembled onto the tie rod. However, existing manual methods are difficult to align directly, or may cause misalignment due to hand pain from long-term work. This application, with the assistance of the guide rod 4, allows for alignment of the gantry crane and tie rod simply by inserting the guide rod 4 into the tie rod, without any other operations. Furthermore, the insertion of the guide rod 4 into the tie rod is a repeatable operation, ensuring that the gantry crane does not shift during assembly and can be accurately inserted into the tie rod. This avoids damage to the gantry crane and tie rod caused by misalignment during assembly, thereby improving the accuracy of gantry crane assembly.

[0028] In this embodiment, the second fixing part 3 includes: a fixing base 301, a first driving member 302, and a clamping block 303. The driving end of the driving mechanism 2 is connected to the fixing base 301. The fixing base 301 is used to support the gantry frame. The first driving member 302 is mounted on the fixing base 301. The clamping block 303 is connected to the driving end of the first driving member 302. The first driving member 302 is used to drive the clamping block 303 to move towards or away from the fixing base 301 and to rotate around the axis of the driving end of the first driving member 302. The clamping block 303 is used to clamp the gantry frame inside the fixing base 301. Thus, the clamping block 303 can clamp the gantry frame to ensure that the installed gantry frame remains stable and does not shift. It can be accurately inserted into the tie rod, avoiding damage to the gantry frame and tie rod due to misalignment of the gantry frame with the tie rod during assembly, thereby improving the accuracy of gantry frame assembly.

[0029] It should be noted that: I. For example Figure 4 As shown, the clamping block 303 is in the avoidance state. At this time, the clamping block 303 is located outside the fixed base 301, which facilitates the transport of the gantry (that is, the gantry is transported from the storage box 7 to the fixed base 301 by the gripping robot). The clamping block 303 will not interfere with the transport of the gantry. II. Figure 5 As shown, the clamping block 303 is in a clamping state. At this time, the clamping block 303 is located inside the fixed base 301 and is in contact with the gantry frame so as to use the clamping block 303 to perform clamping operation on the gantry frame.

[0030] Specifically, the first driving component 302 can be a rotary clamping cylinder, which can simultaneously realize the rotation and lifting operation of the clamping block 303 with one structure. The first driving component 302 can also be a combination of a rotary cylinder and a lifting cylinder, using the rotary cylinder to realize the rotation operation of the clamping block 303 and using the lifting cylinder to realize the lifting operation of the clamping block 303.

[0031] It should be noted that: 1. The first driving component 302 drives the clamping block 303 to move towards or away from the fixed base 301 in the direction of moving along the X-axis. 2. The first driving component 302 drives the clamping block 303 to rotate around the axis where the driving end of the first driving component 302 is located in the Z-axis direction.

[0032] In this embodiment, two first driving members 302 are provided, and the two first driving members 302 are arranged opposite to each other; the number of clamping blocks 303 is equal to the number of first driving members 302. Thus, through the cooperation of the two first driving members 302 and the two clamping blocks 303, the gantry can be clamped from both sides to ensure the stability of the gantry.

[0033] In this embodiment, two guide rods 4 are provided; the guide rods 4 are adapted to the gantry frame and the tie rods. Thus, the two guide rods 4 cooperate with the two tie rods to achieve precise installation of the gantry frame; the adaptation of the guide rods 4 to the gantry frame and the tie rods ensures that the guide rods 4 smoothly pass through the gantry frame and are inserted into the tie rods.

[0034] Specifically, such as Figure 7 , 8 As shown, the gantry frame has two through holes, and two guide rods 4 pass through the two through holes respectively, and are then inserted into the two tie rods respectively; the assembly operation of the gantry frame refers to: the two through holes of the gantry frame pass through the two tie rods respectively, so as to install the gantry frame onto the tie rods.

[0035] In this embodiment, the drive mechanism 2 includes a second drive member 201 and a third drive member 202. The second drive member 201 and the third drive member 202 are connected by a fixing block 203. The drive end of the second drive member 201 is connected to the second fixing part 3, and the second drive member 201 is used to drive the second fixing part 3 to move closer to or further away from the first fixing part 1. The drive end of the third drive member 202 is connected to the guide rod 4 through a push plate 204, and the third drive member 202 is used to drive the guide rod 4 to move closer to or further away from the first fixing part 1. Thus, the second drive member 201 can drive the gantry frame to move to realize the assembly operation of the gantry frame; the third drive member 202 can drive the guide rod 4 to move to insert the guide rod 4 into the pull rod.

[0036] Specifically, the second drive component 201 is connected to the fixed base 301.

[0037] It should be noted that: 1. The direction in which the second driving component 201 drives the second fixed part 3 to move closer to or further away from the first fixed part 1 is: along the X-axis direction; Second, the direction in which the third driving component 202 drives the guide rod 4 to move closer to or further away from the first fixed part 1 is along the X-axis.

[0038] For example, the second driving component 201 is a cylinder, and the third driving component 202 is a cylinder.

[0039] In this embodiment, a drive unit 5 is also included. The drive end of the drive unit 5 is connected to the drive mechanism 2, and the drive unit 5 is used to drive the drive mechanism 2 to move along the Z-axis. Thus, by driving the drive mechanism 2, the second fixing part 3, and the guide rod 4 to move along the Z-axis through the drive unit 5, it is ensured that the drive mechanism 2, the second fixing part 3, and the guide rod 4 will not interfere with the movement of the first fixing part 1, thereby not affecting the assembly operation of the entire tie rod assembly.

[0040] Specifically, the drive end of the drive unit 5 is connected to the fixed block 203.

[0041] For example, the drive unit 5 uses a cylinder.

[0042] In this embodiment, it also includes: a workbench 6, a drive unit 5 connected to the workbench 6, the workbench 6 having a storage box 7 and a gripping robot, the storage box 7 being used to store the gantry frame, and the gripping robot being used to grip the gantry frame stored in the storage box 7 into the second fixing part 3.

[0043] In this embodiment, a conveying unit 8 is also included, with the first fixing part 1 connected to the conveying unit 8. The conveying unit 8 is used to drive the first fixing part 1 to move along the Y-axis direction. Thus, by driving the first fixing part 1 to move along the Y-axis direction through the conveying unit 8, the tie rod is conveyed to the gantry assembly position.

[0044] In this embodiment, it also includes: a base plate 9, a worktable 6, and a conveying unit 8, all of which are connected to the base plate 9.

[0045] The process of gantry assembly operation (i.e., assembling the gantry onto the tie rod) of this utility model is as follows: First, after the assembly of the inner tube rubber sleeve (i.e., the process before the gantry assembly of the tie rod assembly) is completed, the tie rod is transported to the designated position (i.e., the position of the gantry assembly operation) by the conveying unit 8; then, in the initial state, the clamping block 303 is in the avoidance state (e.g., Figure 4 As shown), the gripping robot picks up the gantry from the storage box 7 and places it into the fixed base 301. Then, the first driving component 302 drives the clamping block 303 to move, so that the clamping block 303 is in a clamped state (as shown). Figure 5As shown), the gantry is pressed tightly; then, through the cooperation of the second drive member 201 and the drive unit 5, the position of the guide rod 4 and the gantry is adjusted (that is, the guide rod 4 is aligned with the gantry and the pull rod); next, the third drive member 202 is activated first, so that the guide rod 4 moves towards the side closer to the first fixed part 1, so that the guide rod 4 first passes through the gantry and then inserts into the pull rod. The guide rod 4 can guide the assembly of the gantry. Then the second drive member 201 is activated, so that the fixed seat 301 and the gantry move towards the side closer to the first fixed part 1, so that the gantry is inserted into the pull rod; finally, the first drive member 302 is activated first, so that the clamping block 303 is moved from the clamping state (as shown) to the first fixed part 1. Figure 5 (As shown) Adjust to avoidance state (e.g.) Figure 4 As shown), the gantry frame is freed from the restraint of the fixed seat 301. Then, the second drive component 201 and the third drive component 202 are activated so that the fixed seat 301 and the guide rod 4 move away from the first fixed part 1. This allows the fixed seat 301 and the guide rod 4 to disengage from the tie rod, thus realizing the assembly operation of the gantry frame. The tie rod after the gantry frame assembly is completed is then transported to the position of the large tie rod assembly operation (i.e., the last process of the tie rod assembly gantry frame).

[0046] In summary, this utility model uses a drive mechanism 2 to drive the second fixed part 3 to move closer to the first fixed part 1, thereby achieving automatic assembly of the gantry frame. Compared with the existing manual assembly method, this method has a simple structure and is easy to operate. The drive mechanism 2 enables automatic assembly of the gantry frame, thus improving the assembly efficiency. In addition, before assembling the gantry frame, the guide rod 4 is inserted into the tie rod. The guide rod 4 plays a guiding role during the moving assembly of the gantry frame, ensuring that the gantry frame does not deviate during assembly and can be accurately inserted into the tie rod. This avoids damage to the gantry frame and tie rod due to misalignment of the gantry frame with the tie rod, thereby improving the accuracy of the gantry frame assembly.

Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
