Description

Technical Field

[0001] This utility model relates to the field of pull rod assembly technology, and in particular to a top rod 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 into one unit, greatly facilitating people's travel. The pull rod assembly is the core functional component of a rolling suitcase, including: the pull rod, the roll bar, the top bar, and the handle, etc. Its design directly affects the convenience and durability of the rolling suitcase. During the assembly of the rolling suitcase pull rod assembly, the top bar needs to be attached to the pull rod; therefore, we urgently need a top bar assembly device for rolling suitcase pull rod assemblies.

[0003] Currently, the method for assembling the push rod to the tie rod is manual, which involves manually picking up the push rod and assembling it onto the tie rod. However, this manual method requires aligning the push rod with the tie rod each time, which makes it difficult to align the push rod with the tie rod, is time-consuming and labor-intensive, and affects the assembly efficiency of the push rod. 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 the existing manual assembly of the top rod, this utility model provides a top rod assembly device for a trolley case trolley rod assembly. By improving the structure of the top rod assembly device for the trolley case trolley rod assembly, the top rod can be automatically assembled onto the trolley rod, thereby improving the assembly efficiency of the trolley rod.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a top rod assembly device for a trolley case pull rod assembly, comprising: a driving mechanism, a fixing mechanism, a first driving part, and a fixing seat. The fixing mechanism is installed on the driving end of the driving mechanism. The driving mechanism is used to drive the fixing mechanism to move along the X-axis and Z-axis directions. The fixing mechanism is used to clamp the top rod. The first driving part is connected to the fixing seat. The fixing seat is used to support the pull rod and is slidably connected to the pull rod. The driving end of the first driving part is connected to the pull rod. The first driving part is used to drive the pull rod to move towards or away from the top rod. Wherein: the first driving part drives the pull rod to move towards the side closer to the top rod to assemble the top rod onto the pull rod.

[0006] Therefore, by driving the pull rod towards the side closer to the top rod through the first drive unit, the top rod is automatically assembled. Compared with the existing manual assembly method, this method has a simple structure and is easy to operate. The automatic assembly of the top rod can be achieved by using the first drive unit, thereby improving the assembly efficiency of the top rod. In addition, the fixed mechanism is driven to move along the X-axis and Z-axis directions by the drive mechanism to adjust the position of the top rod relative to the pull rod, so that the top rod and the pull rod are on the same axis. This ensures that the top rod will not deviate during the assembly process and can be accurately inserted into the pull rod. It avoids damage to the top rod and pull rod caused by the top rod not being aligned with the pull rod during the assembly operation, thereby improving the accuracy of the top rod assembly. At the same time, by driving the pull rod to move the assembly top rod, it is possible to avoid the top rod's movement stroke being too long, which would affect the subsequent movement of the pull rod.

[0007] As a further improvement to the above technical solution: the driving mechanism includes a second driving part and a third driving part, the telescopic end of the second driving part is connected to the third driving part, the telescopic end of the third driving part is connected to the fixed mechanism, the second driving part is used to drive the fixed mechanism to move along the X-axis direction, and the third driving part is used to drive the fixed mechanism to move along the Z-axis direction.

[0008] As a further improvement to the above technical solution: the fixing mechanism includes two fourth driving units and two fixing plates. The fourth driving units are connected to the telescopic ends of the third driving units, and the telescopic ends of the fourth driving units are connected to the fixing plates. The fourth driving units are used to drive the fixing plates to move along the Y-axis direction. The two fixing plates are used together to clamp the push rod. Thus, by having the two fixing plates clamp the push rod together, the push rod remains stable during assembly and will not shift relative to the pull rod.

[0009] As a further improvement to the above technical solution: a mounting groove is provided on the side of the fixing plate away from the fourth driving part, and the cross-sectional shape of the mounting groove is V-shaped. Therefore, since the cross-sectional shape of the push rod is circular, the V-shaped mounting grooves on the two fixing plates form a rhomboid mounting space. The push rod is placed within this mounting space, and the push rod abuts against the side wall of the V-shaped mounting groove. This ensures that the push rod remains stable during assembly and will not shift relative to the tie rod.

[0010] As a further improvement to the above technical solution: two fixing mechanisms are provided.

[0011] As a further improvement to the above technical solution: the fixing base is provided with two fixing blocks, and the pull rod is inserted into the fixing blocks and slidably connected to them. Thus, by sliding the pull rod to the fixing blocks, the pull rod can move towards or away from the top rod. When the pull rod moves towards the top rod, the movement is used for the assembly of the top rod; when the pull rod moves away from the top rod, the movement is used for the return operation after the top rod assembly.

[0012] As a further improvement to the above technical solution: the telescopic end of the first drive unit is provided with a push rod, which is inserted into the pull rod and connected to the pull rod; there are two push rods in total.

[0013] As a further improvement to the above technical solution: a limiting protrusion is provided at the end of the push rod away from the first driving part. The limiting protrusion is adapted to a limiting groove on the pull rod, and the limiting protrusion is inserted into the limiting groove to connect the push rod and the pull rod. Thus, through the working method of the limiting protrusion and the limiting groove, the pull rod will not disengage from the push rod during the process of moving towards the top rod and moving away from the top rod, facilitating the assembly of the top rod and the return to its original position after assembly.

[0014] As a further improvement to the above technical solution, it also includes a conveying unit, to which both the first driving unit and the fixed seat are connected. The conveying unit is used to drive the first driving unit and the fixed seat to move along the Y-axis. Thus, by driving the first driving unit and the fixed seat to move along the Y-axis via the conveying unit, the pull rod is conveyed to the position for top rod assembly.

[0015] As a further improvement to the above technical solution, it also includes: a base plate, the conveying unit being connected to the base plate, the driving mechanism being connected to the base plate via a worktable, and the worktable being used to place the top rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a first driving unit to drive the pull rod to move closer to the top rod, thereby achieving automatic assembly of the top rod. Compared with the existing manual assembly method, this method has a simple structure and is easy to operate. The use of the first driving unit to drive the top rod enables automatic assembly, thus improving the assembly efficiency of the top rod. In addition, the driving mechanism drives the fixing mechanism to move along the X-axis and Z-axis directions to adjust the position of the top rod relative to the pull rod, thereby ensuring that the top rod and the pull rod are on the same axis. This ensures that the top rod will not deviate during the assembly process and can be accurately inserted into the pull rod, avoiding damage to the top rod and pull rod caused by the top rod not being aligned with the pull rod during the assembly operation. This improves the accuracy of the top rod assembly. At the same time, by driving the pull rod to move the assembly top rod, it is possible to avoid the top rod's movement stroke being too long, which would affect the subsequent movement of the pull rod.

[0017] 2. In this utility model, the top rod has a circular cross-sectional shape, and the V-shaped mounting grooves on the two fixing plates form a rhomboid mounting space. The top rod is placed in this mounting space, and the top rod abuts against the side wall of the V-shaped mounting groove. In this way, it is ensured that the top rod remains stable during the assembly process and will not shift relative to the tie rod.

[0018] 3. This utility model uses a sliding connection between the pull rod and the fixed block to allow the pull rod to move towards or away from the top rod. When the pull rod moves towards the top rod, the movement of the pull rod is used for the assembly operation of the top rod. When the pull rod moves away from the top rod, the movement of the pull rod is used for the return operation after the top rod assembly operation.

[0019] 4. This utility model uses a working method in which the limiting protrusion and the limiting groove cooperate to ensure that the pull rod will not break free from the restraint of the push rod when it moves towards the side closer to the top rod or away from the top rod, so as to facilitate the assembly operation of the top rod and the return operation after 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 6 The diagram shows the preferred embodiment of this utility model. The top rod assembly device for the trolley case pull rod assembly of this embodiment includes: a drive mechanism 1, a fixing mechanism 2, a first drive part 4, and a fixing seat 5. The fixing mechanism 2 is installed on the drive end of the drive mechanism 1. The drive mechanism 1 is used to drive the fixing mechanism 2 to move along the X-axis and Z-axis directions. The fixing mechanism 2 is used to clamp the top rod 3. The first drive part 4 is connected to the fixing seat 5. The fixing seat 5 is used to support the pull rod 6 and is slidably connected to the pull rod 6. The drive end of the first drive part 4 is connected to the pull rod 6. The first drive part 4 is used to drive the pull rod 6 to move towards or away from the top rod 3. Specifically, the first drive part 4 drives the pull rod 6 to move towards the side closer to the top rod 3 so as to assemble the top rod 3 onto the pull rod 6. Therefore, by driving the pull rod 6 towards the side closer to the top rod 3 through the first drive unit 4, the top rod 3 is automatically assembled. Compared with the existing manual assembly method, this method has a simple structure and is easy to operate. The automatic assembly of the top rod 3 can be achieved by using the first drive unit 4, thereby improving the assembly efficiency of the top rod 3. In addition, the fixed mechanism 2 is driven by the drive mechanism 1 to move along the X-axis and Z-axis directions to adjust the position of the top rod 3 relative to the pull rod 6, so that the top rod 3 and the pull rod 6 are on the same axis. This ensures that the top rod 3 will not deviate during the assembly process and can be accurately inserted into the pull rod 6. It avoids damage to the top rod 3 and the pull rod 6 due to the top rod 3 not being aligned with the pull rod 6 during the assembly operation, thereby improving the assembly accuracy of the top rod 3. At the same time, by driving the pull rod 6 to move the assembly top rod 3, the excessive travel of the top rod 3 can be avoided, which would affect the subsequent movement of the pull rod 6.

[0027] In other words, during the assembly of the push rod 3, it is necessary to align the push rod 3 with the pull rod 6 so that the push rod 3 can be directly assembled onto the pull rod 6. However, the existing manual method is difficult to align directly or may cause misalignment due to hand pain from long-term operation. This application uses the fixing mechanism 2 to fix the push rod 3 first. By simply moving the pull rod 6, the assembly of the push rod 3 and the pull rod 6 can be achieved. Moreover, the operation of fixing the push rod 3 with the fixing mechanism 2 is a repeatable operation, which ensures that the push rod 3 will not be misaligned during the assembly process and can be accurately inserted into the pull rod 6. This avoids damage to the push rod 3 and pull rod 6 caused by the push rod 3 not being aligned with the pull rod 6 during the assembly operation, thereby improving the accuracy of the push rod 3 assembly.

[0028] In other words, both the push rod 3 and the pull rod 6 are slender structures. To achieve the assembly operation between the push rod 3 and the pull rod 6, the push rod 3 or the pull rod 6 needs to have a long travel. However, the long travel of the push rod 3 will result in a long travel of the drive component of the push rod 3, which will interfere with the movement of the pull rod 6 after assembly. Therefore, by driving the pull rod 6 to move and assemble the push rod 3, the excessive travel of the push rod 3 can be avoided from affecting the subsequent movement of the pull rod 6.

[0029] It should be noted that the direction in which the first drive unit 4 drives the pull rod 6 to move closer to or further away from the push rod 3 is along the X-axis.

[0030] For example, the first drive unit 4 uses a cylinder.

[0031] In this embodiment, the drive mechanism 1 includes a second drive unit 101 and a third drive unit 102. The telescopic end of the second drive unit 101 is connected to the third drive unit 102, and the telescopic end of the third drive unit 102 is connected to the fixing mechanism 2. The second drive unit 101 is used to drive the fixing mechanism 2 to move along the X-axis direction, and the third drive unit 102 is used to drive the fixing mechanism 2 to move along the Z-axis direction. For example, the second drive unit 101 and the third drive unit 102 are both pneumatic cylinders.

[0032] In this embodiment, the fixing mechanism 2 includes two fourth driving units 201 and two fixing plates 202. The fourth driving units 201 are connected to the telescopic ends of the third driving units 102, and the telescopic ends of the fourth driving units 201 are connected to the fixing plates 202. The fourth driving units 201 are used to drive the fixing plates 202 to move along the Y-axis direction. The two fixing plates 202 are used together to clamp the top rod 3. A mounting groove 203 is provided on the side of the fixing plate 202 away from the fourth driving units 201. The cross-sectional shape of the mounting groove 203 is V-shaped. There are two fixing mechanisms 2 in total. Therefore, the top rod 3 is clamped by the two fixing plates 202, so that the top rod 3 remains stable during the assembly process and will not shift relative to the tie rod 6. Since the cross-sectional shape of the top rod 3 is circular, the V-shaped mounting grooves 203 on the two fixing plates 202 form a rhomboid mounting space. The top rod 3 is placed in this mounting space, and the top rod 3 abuts against the side wall of the V-shaped mounting groove 203. In this way, it is ensured that the top rod 3 remains stable during the assembly process and will not shift relative to the tie rod 6.

[0033] For example, the fourth drive unit 201 uses a cylinder.

[0034] In this embodiment, the fixing base 5 is provided with two fixing blocks 501. The pull rod 6 is inserted into the fixing block 501 and slidably connected to the fixing block 501. Thus, by sliding the pull rod 6 to the fixing block 501, the pull rod 6 can move towards or away from the top rod 3. When the pull rod 6 moves towards the top rod 3, the movement of the pull rod 6 is used for the assembly operation of the top rod 3. When the pull rod 6 moves away from the top rod 3, the movement of the pull rod 6 is used for the return operation after the top rod 3 has been assembled.

[0035] In this embodiment, the telescopic end of the first drive unit 4 is provided with a push rod 401, which is inserted into and connected to the pull rod 6. Two push rods 401 are provided. A limiting protrusion 402 is provided at the end of the push rod 401 away from the first drive unit 4. The limiting protrusion 402 is adapted to a limiting groove 601 on the pull rod 6, and is inserted into the limiting groove 601 to connect the push rod 401 to the pull rod 6. Thus, through the working method of the limiting protrusion 402 cooperating with the limiting groove 601, the pull rod 6 will not disengage from the push rod 401 during the process of moving towards the top rod 3 and moving away from the top rod 3, facilitating the assembly of the top rod 3 and the subsequent return to its original position.

[0036] In this embodiment, the system further includes a conveying unit 7 and a base plate 8. The first driving unit 4 and the fixed seat 5 are both connected to the conveying unit 7. The conveying unit 7 drives the first driving unit 4 and the fixed seat 5 to move along the Y-axis. The conveying unit 7 is connected to the base plate 8. The driving mechanism 1 is connected to the base plate 8 via a worktable 9, which is used to place the push rod 3. Thus, by driving the first driving unit 4 and the fixed seat 5 along the Y-axis via the conveying unit 7, the pull rod 6 is conveyed to the assembly position of the push rod 3.

[0037] Specifically, the second drive unit 101 is connected to the connecting block 10, the connecting block 10 is connected to the worktable 9, and the worktable 9 is connected to the base plate 8.

[0038] The assembly process of the push rod 3 of this utility model (i.e., the assembly of the push rod 3 onto the tie rod 6) is as follows: First, after the assembly of the large-size tie rod cylinder (i.e., the process before the assembly of the push rod 3 of the tie rod 6 assembly) is completed, the tie rod 6 is transported to the designated position (i.e., the position for the assembly of the push rod 3) by the conveying unit 7; then, the push rod 3 to be assembled is fixed by the fixing mechanism 2, and the position of the push rod 3 is adjusted by the driving mechanism 1 so that the push rod 3 and the tie rod 6 are on the same axis; finally, the first driving unit 4 is activated, and the tie rod 6 is driven by the first driving unit 4 to move towards the side closer to the push rod 3 so that the push rod 3 is inserted into the tie rod 6, thus realizing the assembly of the push rod 3.

[0039] In summary, this utility model uses the first driving unit 4 to drive the pull rod 6 to move closer to the top rod 3, thereby achieving automatic assembly of the top rod 3. Compared with the existing manual assembly method, this method has a simple structure and is easy to operate. The use of the first driving unit 4 to drive the top rod 3 enables automatic assembly, thus improving the assembly efficiency of the top rod 3. In addition, the driving mechanism 1 drives the fixing mechanism 2 to move along the X-axis and Z-axis directions to adjust the position of the top rod 3 relative to the pull rod 6, thereby ensuring that the top rod 3 and the pull rod 6 are on the same axis. This ensures that the top rod 3 will not deviate during the assembly process and can be accurately inserted into the pull rod 6. It avoids damage to the top rod 3 and pull rod 6 due to the top rod 3 not being aligned with the pull rod 6 during the assembly operation, thus improving the assembly accuracy of the top rod 3. At the same time, by driving the pull rod 6 to move the assembly top rod 3, it is possible to avoid the top rod 3's movement stroke being too long, which would affect the subsequent movement of the pull rod 6.

[0040] The above description is based on the preferred embodiments of this utility model. 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. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
