Description

Technical Field

[0001] This utility model relates to a concentric alignment device for sleeves of two different diameters, belonging to the field of sleeve docking. Background Technology

[0002] In modern industrial production lines, automated equipment is widely used for connecting sleeves. A typical scenario is to precisely fit a larger-diameter outer sleeve onto a smaller-diameter inner sleeve at a designated outer position to complete the assembly.

[0003] Currently, automating this process still faces significant technical bottlenecks, with the core challenge being the automatic concentric alignment of the inner and outer sleeves. Specifically, there is an inherent gap between the outer and inner sleeves. During automated feeding and fitting, it is crucial to ensure strict concentricity between the two; otherwise, interference or collisions between the sleeve openings can easily occur, preventing successful fitting, damaging the sleeve edges, or even jamming the equipment, forcing the production line to stop. Therefore, the industry typically uses manual methods for fitting, which undoubtedly increases production costs and speed.

[0004] In view of this, it is indeed necessary to improve the existing concentric alignment device to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a concentric alignment device for sleeves of two different diameters, which can easily complete the docking of sleeves of two different diameters.

[0006] The technical solution of this utility model is:

[0007] A concentric alignment device for sleeves of two different diameters, comprising:

[0008] A fixing module is used to fix the main bushing.

[0009] An alignment device is disposed near the fixing module and has an alignment cavity. The alignment cavity includes a first alignment cavity near the fixing module and a second alignment cavity away from the fixing module. The first alignment cavity and the second alignment cavity are in communication with each other. The main sleeve passes through the first alignment cavity and is at least partially located in the second alignment cavity.

[0010] The clamping module is used to clamp the main sleeve and place it in the fixing module, and to clamp the secondary sleeve and place the secondary sleeve portion within the second alignment cavity;

[0011] A pushing module is located on the side of the alignment device relative to the fixing module and is used to push the sub-sleeve into the second alignment cavity.

[0012] As a further improvement of this utility model, the inner diameter of the first alignment cavity is smaller than the inner diameter of the second alignment cavity.

[0013] As a further improvement of this utility model, the diameter of the main sleeve is smaller than the diameter of the secondary sleeve, and the diameter of the secondary sleeve is larger than the inner diameter of the first alignment cavity.

[0014] As a further improvement of this utility model, the length of the first alignment cavity is between one-third and one-fifth of the length of the second alignment cavity.

[0015] As a further improvement of this utility model, the alignment module includes a first alignment module and a second alignment module arranged opposite to each other. The first alignment module and the second alignment module are configured to be able to move closer to each other or further away from each other. Both the first alignment module and the second alignment module are provided with alignment grooves. When the first alignment module and the second alignment module move closer to each other until they fit together, the two alignment grooves merge to form the alignment cavity.

[0016] As a further improvement of this utility model, when the first alignment module and the second alignment module approach each other to fit together, the main sleeve, the alignment cavity, the auxiliary sleeve and the pushing module are located on the same horizontal line.

[0017] As a further improvement of this utility model, the fixing module includes a support platform and an opening and closing part that can be opened and closed relative to the support platform, and the main sleeve is restricted between the support platform and the opening and closing part.

[0018] As a further improvement of this utility model, the support platform is provided with a support groove, the main sleeve is confined within the support groove, and the support groove, the alignment cavity and the push module are located on the same horizontal line.

[0019] As a further improvement of this utility model, the length of the supporting groove is between one-third and one-fifth of the length of the main sleeve.

[0020] As a further improvement of this utility model, the pushing module includes a carrier movable relative to the alignment module, and a pushing part disposed on the carrier and extending toward the alignment module, the pushing part being used to push the sub-sleeve into the second alignment cavity.

[0021] The beneficial technical effects of this utility model are as follows: The concentric alignment device of this utility model for two sleeves of different diameters is provided by setting a first alignment cavity and a second alignment cavity that are interconnected in the alignment cavity of the alignment module, so that the main sleeve passes through the first alignment cavity and is at least partially located in the second alignment cavity, and the auxiliary sleeve is partially located in the second alignment cavity. Then, under the action of the pushing module, the auxiliary sleeve is pushed into the second alignment cavity and docked with the main sleeve. In this way, docking can be easily completed and labor costs are reduced. Attached Figure Description

[0025] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0026] Please see Figures 1 to 3 As shown, this utility model discloses a concentric alignment device 100 for two different diameter sleeves. The sleeve includes a main sleeve and a secondary sleeve. The concentric alignment device 100 is used to connect the main sleeve and the secondary sleeve to each other, and includes a fixing module 1, an alignment module 2, a clamping module and a pushing module 3.

[0027] The fixing module 1 is used to fix the main sleeve and includes a support platform 11 and an opening / closing part 12 that can open and close relative to the support platform 11. The main sleeve is confined between the support platform 11 and the opening / closing part 12. The clamping module is configured to clamp the main sleeve and place it on the fixing module 1. When the clamping module clamps the main sleeve onto the fixing module 1, the opening / closing part 12 opens to expose the support platform 11 for the main sleeve to be placed. Then, the opening / closing part 12 closes and confines the main sleeve to the support platform 11.

[0028] Preferably, the support platform 11 is provided with a support groove 111, and the main sleeve is confined within the support groove 111.

[0029] The alignment module 2 is disposed near the fixing module 1 and has an alignment cavity. The alignment cavity includes a first alignment cavity 21 near the fixing module 1 and a second alignment cavity 22 away from the fixing module 1. The first alignment cavity 21 and the second alignment cavity 22 are interconnected. The main sleeve passes through the first alignment cavity 21 and is at least partially located within the second alignment cavity 22. The clamping module is used to clamp and place the main sleeve on the fixing module 1, and to clamp the auxiliary sleeve so that the auxiliary sleeve is partially located within the second alignment cavity 22. Therefore, in this embodiment, the main sleeve and the auxiliary sleeve are aligned within the second alignment cavity 22.

[0030] The pushing module 3 is located on the side of the alignment module 2 opposite to the fixing module 1, and is used to push the secondary sleeve into the second alignment cavity 22. Thus, through the pushing of the pushing module 3, the secondary sleeve is fitted onto the main sleeve.

[0031] Preferably, the supporting groove 111, the alignment cavity, and the pushing module 3 are located on the same horizontal line. The pushing module 3 includes a carrier 31 that is movable relative to the alignment module 2, and a pushing part 32 disposed on the carrier 31 and extending toward the alignment module 2, the pushing part 32 being used to push the sub-sleeve into the second alignment cavity 22.

[0032] In this embodiment, the secondary sleeve is fitted around the outer periphery of the primary sleeve, therefore the diameter of the primary sleeve is smaller than the diameter of the secondary sleeve. The inner diameter of the first alignment cavity 21 is also correspondingly smaller than the inner diameter of the second alignment cavity 22. The diameter of the secondary sleeve is larger than the inner diameter of the first alignment cavity 21. Thus, when the secondary sleeve is pushed, it is blocked by the cavity wall of the first alignment cavity 21 to ensure its proper fit.

[0033] Preferably, the length of the first alignment cavity 21 is between one-third and one-fifth of the length of the second alignment cavity 22. This ensures that the main sleeve can extend into the second alignment cavity 22, and the length of its insertion into the second alignment cavity 22 is sufficient. This is because, in this embodiment, auxiliary sleeves need to be fitted onto both sides of the main sleeve, while the center position needs to be preserved. Therefore, the groove length of the supporting groove 111 is between one-third and one-fifth of the length of the main sleeve. Thus, the center position of the main sleeve can also be preserved through the supporting groove 111.

[0034] The alignment module 2 includes a first alignment module 23 and a second alignment module 24 disposed opposite to each other. The first alignment module 23 and the second alignment module 24 are configured to move closer to or further away from each other. Both the first alignment module 23 and the second alignment module 24 are provided with alignment grooves 20. When the first alignment module 23 and the second alignment module 24 approach each other to fit together, the two alignment grooves 20 merge to form the alignment cavity. Therefore, each alignment groove 20 has a portion forming the first alignment cavity 21 and the second alignment cavity 22. In use, the first alignment module 23 and the second alignment module 24 are separated from each other, and the main sleeve and the auxiliary sleeve are both partially located between the first alignment module 23 and the second alignment module 24. When the first alignment module 23 and the second alignment module 24 merge, the main sleeve and the auxiliary sleeve are both partially located within the alignment cavity.

[0035] When the first alignment module 23 and the second alignment module 24 approach each other to fit together, the main sleeve, the alignment cavity, the auxiliary sleeve, and the pushing module 3 are located on the same horizontal line.

[0036] In summary, the concentric alignment device 100 of this utility model for sleeves of two different diameters provides a first alignment cavity 21 and a second alignment cavity 22 that are interconnected within the alignment cavity of the alignment module 2. The main sleeve is inserted into the first alignment cavity 21 and at least partially located within the second alignment cavity 22, while the secondary sleeve is partially located within the second alignment cavity 22. Then, under the action of the pushing module 3, the secondary sleeve is pushed into the second alignment cavity 22 and docked with the main sleeve. This allows for easy docking and reduces labor costs.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
