[0036] In this embodiment, the clamping jaw 45 of the clamping cylinder 44 clamps the annular seat 11, the guiding seat 47 is guided and assisted by the guiding driving power 42, the linear driving power 8 acts to place the annular seat 11 on the assembly object (such as the rod part 12 of the semi-finished assembly) through the clamping jaw 45, and then the clamping cylinder 44 is loosened, and the limiting pressing block 46 exerts force downward on the annular seat 11 to press-fit, so that the guiding press-fitting unit 4 combined with the linear driving power 8 realizes the sleeving assembly and press-fitting action of the annular seat 11.

[0037] As Figure 4 shown, the guiding block 471 of L-shaped structure is installed at the bottom end of the guiding seat 47, the vertical arm of the guiding block 471 is fitted to the guiding seat 47, and the horizontal arm of the guiding block 471 is provided with a guiding hole, which is located directly above the limiting pressing block 46.

[0038] In this embodiment, the guiding block 471 on the guiding seat 47 is sleeved on the rod part 12 of the external semi-finished assembly through the guiding hole, realizing the guiding support of the rod part 12 during the assembly process, and facilitating the assembly operation.

[0039] In actual use, the guiding hole can also be set to a structure similar to the rod part 12 according to actual needs, such as the matching structure of the concave groove and the convex rib on the inner wall surface of the guiding hole and the outer wall surface of the rod part 12, so that the guiding support of the rod part 12 is realized, and the self-rotation of the rod part 12 is effectively prevented through the sleeving of the guiding block 471 on the rod part 12.

[0040] In actual use, the guiding block 471 can be replaced according to actual assembly needs to be suitable for corresponding product models, effectively improving the use flexibility.

[0041] The vertical long hole 4710 is formed on the vertical arm of the guiding block 471, and the external fastener is locked on the guiding seat 47 after passing through the vertical long hole 4710; in actual use, the installation height of the guiding block 471 on the guiding seat 47 can be adjusted through the vertical long hole 4710 to adapt to different assembly needs.

[0044] In this embodiment, in the use process, the rod part 12 of the external semi-finished product assembly passes through the cylindrical seat 461 upward, so that the cylindrical seat 461 is sleeved on the rod part 12 above the annular seat 11, which facilitates the cylindrical seat 461 to press downward on the annular seat 11 from the circumferential direction, effectively ensures that the annular seat 11 is matched with the clamping of the support part 13 in the semi-finished product assembly, and the press-fitting reliability is high.

[0045] The bottom end of the cylindrical seat 461 constitutes a downward pressing surface.

[0046] When the annular seat 11 is clamped by the clamping jaws 45 of the clamping cylinder 44, the contact between the bottom surface of the cylindrical seat 461 and the top surface of the annular seat 11 can also realize the limiting of the annular seat 11 during clamping, effectively ensuring the height position of the annular seat 11.

[0049] As Figure 2 shown, the vertical guide rail 81 above the lower support 41 is slidingly fitted with the upper support 6, the upper support 6 is connected to the output end of the linear driving power 8, and the elastic component 5 is installed between the upper support 6 and the lower support 41 of the guide press-fitting unit 4.

[0050] By arranging the elastic component 5 between the lower support 41 and the upper support 6, the linear driving power 8 pushes the upper support 6 to move downward, pushes the lower support 41 to move through the elastic component 5, and makes the lifting driving power 9, the linear driving power 8 and the guide driving power 42 act, so that the guide press-fitting unit 4 can have a certain elastic buffer when it is contacted and forced, etc., avoiding hard touch.

[0051] The structure of the elastic component 5 is as follows: it includes a vertical rod fixedly installed at the bottom of the lower support 41, the vertical rod extends upward through the upper support 6, and an elastic element is fitted on the vertical rod located between the upper support 6 and the lower support 41; a limiting block for preventing detachment is provided at the top of the vertical rod, and the limiting block prevents the vertical rod from detaching from the upper support 6.

[0055] In this embodiment, the guide drive power 42 is one of the existing hydraulic cylinder, pneumatic cylinder, or electric cylinder, which can realize the up and down movement of the guide seat 47 via the guide drive power 42.

[0056] The method of using this utility model is as follows:

[0057] like Figure 5 As shown, during assembly, the external semi-finished component is supported on the accompanying fixture of the conveyor line. The annular seat 11 is clamped from the linear vibrator 1 by the clamping cylinder 44 and the gripper 45. Combined with the operation of the lifting drive power 9 and the horizontal moving module 2, the annular seat 11 is moved to directly above the semi-finished component. The linear drive power 8 operates, driving the guide drive power 42, clamping cylinder 44, gripper 45, limit pressure block 46, guide seat 47, and guide block 471 downwards via the lower support 41. The annular seat 11 is lowered and fitted onto the rod 12 of the semi-finished component. After the rod 12 passes upward through the limiting pressure block 46, the guide block 471 is fitted onto the rod 12 until the annular seat 11 is placed at the bottom of the rod 12. The clamping cylinder 44 releases its clamp on the annular seat 11, and the linear drive 8 continues to operate. The bottom end of the limiting pressure block 46 contacts and applies force to the annular seat 11, driving the annular seat 11 to move downward and be clamped onto the lower support 13. The installation of the annular seat 11 is completed.

[0058] After the installation of the annular seat 11, the annular seat 11 is clamped again by the clamping cylinder 44 through the clamping jaw 45, and the semi-finished product assembly is temporarily fixed, the guiding driving power 42 is first actuated to move upward and separate from the rod part 12 through the guiding seat 47 and the guiding block 471, and then the clamping cylinder 44 is loosened; the upward separation of the guiding block 471 is effectively prevented from moving the semi-finished product assembly; and it is especially suitable for the case that the self-rotating limiting structure is arranged between the guiding block 471 and the rod part 12.

[0059] The annular seat is sleeved and assembled and is pressed and assembled by the guiding and pressing assembly unit combined with the linear driving power, the overall structure is simplified, the layout is reasonable and ingenious, the assembly effect is good, and the efficiency is high.

[0060] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same and similar parts between the various embodiments can be referred to each other.

[0061] The above description is an explanation of the utility model, not a limitation of the utility model, the range defined by the utility model is referred to the claims, and any form of modification is allowed within the protection range of the utility model.
