[0033] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.
[0034] like Figure 1 As shown, a floating clamping rotation mechanism of the present embodiment includes a back plate 1, a support 2 is installed on the side of the back plate 1, a transmission component 3 is installed to penetrate the support 2 and rotate the back plate 1 front and back, and the front end of the transmission component 3 is connected with the inner support clamping component 6 through the floating component 7; it also includes a floating linkage seat 5 installed on the support 2 for forward and backward sliding, one end of the floating linkage seat 5 is connected to the floating component 7, and the other end of the floating linkage seat 5 is installed with the inner support unlocking power 4, and the floating linkage seat 5 enables the inner support unlocking power 4 to move synchronously with the floating component 7 and the inner support clamping component 6 in the front and rear directions.
[0035] In this embodiment, when the inner support clamping assembly 6 is in close contact with the external clamped part, the floating assembly 7 can achieve floating buffering to effectively avoid collision or damage, and the inner support unlocking power 4 is placed outside the inner support clamping assembly 6 to simplify the structure. The floating linkage seat 5 effectively ensures that the inner support unlocking power 4 can move synchronously with the inner support clamping assembly 6.
[0036] When the inner support clamping assembly 6 floats and buffers with the floating assembly 7, the inner support unlocking power 4 is driven to move synchronously through the floating linkage seat 5, so that the movement stability of the inner support clamping assembly 6 when the power is working is effectively guaranteed while the power is externalized.
[0037] like Figure 2As shown, the structure of the floating linkage seat 5 is as follows: it includes a U-shaped member 52 with an opening facing downward, the U-shaped member 52 spans across the back plate 1 and the support 2 from front to back, and a sliding guide assembly 51 is installed between the inner bottom surface of the U-shaped member 52 and the top surface of the support 2; linkage wheels 53 are symmetrically installed at the bottom end of the vertical arm in front of the U-shaped member 52, and an annular groove 70 is opened on the floating assembly 7, and the linkage wheel 53 is fitted into the annular groove 70; an inner support unlocking power 4 is installed on the vertical arm behind the U-shaped member 52; through the embedded matching of the linkage wheel 53 and the annular groove 70, when the floating assembly 7 floats and moves, it can reliably drive the floating linkage seat 5 to move synchronously, thereby stably maintaining the synchronous movement of the inner support unlocking power 4, effectively ensuring the reliability of the action of the inner support unlocking power 4, and the setting of the floating linkage seat 5 does not affect the rotation of the floating assembly 7 and the inner support clamping assembly 6.
[0038] In this embodiment, the sliding guide assembly 51 can adopt a commercially available guide rail slider assembly.
[0039] like Figure 3 As shown, the structure of the transmission assembly 3 is: it includes a rotating shaft cylinder 32 that passes through the support 2 and the back plate 1 front and back, a bearing is installed between the outer wall of the rotating shaft cylinder 32 and the support 2 and the back plate 1 to form a rotational fit, and a push rod 33 is installed along the axial direction of the rotating shaft cylinder 32; a transmission wheel 31 is installed after one end of the rotating shaft cylinder 32 extends out of the back plate 1, and the transmission wheel 31 is connected with the external rotation power through the belt assembly 9, and a floating assembly 7 is installed after the other end of the rotating shaft cylinder 32 extends out of the support 2.
[0040] In this embodiment, the transmission assembly 3 is driven to rotate by the external rotational power through the belt assembly 9, and then the inner support clamping assembly 6 is driven to rotate through the floating assembly 7, so that the inner support clamping assembly 6 clamps the clamped part for rotation; in addition, the floating shaft rod 64 in the inner support clamping assembly 6 can be pushed by the push rod 33 by the internal support unlocking power 4 to realize the clamping and unlocking of the internal support unlocking power 4.
[0041] The push rod 33 extends backwards from the rotating shaft cylinder 32, and the end block 30 is installed at the rear end of the push rod 33, and the end block 30 supports the power output end of the unlocking power 4 in correspondence.
[0042] In this embodiment, the radial dimension of the end block 30 is larger than the push rod 33, which can effectively prevent the push rod 33 from axially escaping from the rotating shaft tube 32. In actual use, the end block 30 can be made of flexible materials such as rubber.
[0043] like Figure 3 and Figure 4As shown, the structure of the floating assembly 7 is: it includes a floating sleeve 71 which is mounted on the end of the rotating shaft cylinder 32, the inner wall surface of the floating sleeve 71 extends backward along the circumferential direction to form an inner convex ring 711, the inner convex ring 711 is matched with the convex edge 331 at the end of the push rod 33, and a floating spring 72 is installed between the inner convex ring 711 and the rotating shaft cylinder 32 to form a floating fit; the front part of the floating sleeve 71 is installed with an inner support clamping assembly 6.
[0044] In this embodiment, a floating buffer distance is set axially between the floating sleeve 71 in the floating assembly 7 and the rotating shaft tube 32. The floating buffer distance is realized and maintained by the floating spring 72. When floating is generated by external force, the floating spring 72 is compressed.
[0045] In this embodiment, the elastic force of the floating spring 72 drives the inner convex ring 711 away from the rotating shaft cylinder 32, and the axial floating clearance between the floating sleeve 71 and the rotating shaft cylinder 32 is at the maximum state; when the front end of the floating sleeve 71 is touched or subjected to external force, the floating sleeve 71 moves axially backward toward the rotating shaft cylinder 32, and the floating spring 72 is compressed to achieve floating buffering; Figure 4 In the middle, the axial floating clearance between the floating sleeve 71 and the rotating shaft cylinder 32 is in the minimum state.
[0046] The fastener is locked through the wall of the floating sleeve 71 from the outside to the inside and faces the rotating shaft cylinder 32. The floating sleeve 71 is provided with a long hole 712 arranged along the axial direction for the fastener to pass through and move, and the rotating shaft cylinder 32 is provided with a matching hole 321 for the fastener to lock, so that the floating sleeve 71 can rotate with the rotating shaft cylinder 32 and there is a floating buffer in the axial direction.
[0047] like Figure 3 and Figure 6 As shown, the structure of the inner support clamping assembly 6 is as follows: it includes a floating shaft cylinder 63 axially extending into the floating sleeve 71 from the front, the floating shaft cylinder 63 is fixedly matched with the floating sleeve 71, a floating shaft rod 64 is installed axially through the floating shaft cylinder 63, the floating shaft rod 64 is located axially in front of the push rod 33, and an inner support spring 62 is installed between the floating shaft rod 64 and the floating shaft cylinder 63; an expansion sleeve 66 is sleeved on the floating shaft rod 64 located in front of the floating shaft cylinder 63, and the front end of the floating shaft rod 64 and the expansion sleeve 66 are matched through a conical structure 60, as shown in FIG. Figure 5 As shown, through the relative movement at the conical surface, the expansion sleeve 66 is expanded or retracted, thereby achieving a change in the diameter of the outer wall surface.
[0048] In this embodiment, the elastic force of the inner support spring 62 drives the floating shaft 64 and the floating shaft tube 63 to maintain a preset relative position. At this time, the expansion sleeve 66 matching the conical surface of the floating shaft 64 is stretched outward in a circumferential direction and is in an inner support state; when the inner support unlocking power 4 pushes the floating shaft 64 through the push rod 33, the floating shaft 64 moves axially forward relative to the expansion sleeve 66, and the expansion sleeve 66 is retracted inward in a circumferential direction under the action of its own elastic force and is in an inner support unlocking state.
[0049] In this embodiment, the internal support unlocking power 4 is arranged at intervals behind the internal support clamping assembly 6 and the transmission assembly 3. In the internal support clamping assembly 6, the expansion sleeve 66 is maintained in an outwardly stretched and internally supported state under the elastic force of the internal support spring 62, and the internal support unlocking power 4 is unlocked when it is working, thereby effectively separating the internal support unlocking power 4 from the transmission assembly 3 and the belt assembly 9. When the internal support unlocking power 4 is not working and is separated from the transmission assembly 3, the belt assembly 9 drives the transmission assembly 3, the floating assembly 7, and the internal support clamping assembly 6 to rotate.
[0050] The expansion sleeve 66 is a multi-petal structure, and the front end of the inner wall of the expansion sleeve 66 is matched with the front conical surface of the outer wall of the floating shaft rod 64. When subjected to external support force, the interval between the petals increases, the diameter of the expansion sleeve 66 increases and expands outward in the circumferential direction. After the external support force is removed, the expansion sleeve 66 retracts under the action of its own performance; an end cover 65 is installed on the floating shaft tube 63 at the rear end of the expansion sleeve 66.
[0051] The rear end of the floating shaft 64 is equipped with a sleeve 61, which abuts against the end of the inner support spring 62 to achieve the installation of the inner support spring 62 on the floating shaft 64 and facilitate actual processing and assembly; an insert block 73 is inserted from the outside to the inside through the floating sleeve 71 toward the floating shaft tube 63.
[0052] A support assembly 8 is inserted and fixed on the back plate 1 , and the support assembly 8 is supported on the bottom surface of the support 2 .
[0053] In this embodiment, a support 2 is installed on the side of the back plate 1 as a structural basis for installing the transmission component 3 and the floating linkage seat 5, thereby effectively ensuring their installation stability on the back plate 1; by setting the supporting component 8 below the support 2, the structural reliability of the support 2 installed on the back plate 1 is effectively guaranteed.
[0054] The usage of the utility model is:
[0055] When the clamped part, such as a round tube, moves with the moving part to the front of the inner support clamping assembly 6, the back plate 1 moves forward under the action of the external power, and at the same time, the inner support unlocking power 4 works to cause the end of the inner support clamping assembly 6 to be radially retracted inward and in an unlocked state; after the inner support clamping assembly 6 moves and extends into the round tube, the inner support unlocking power 4 works in the reverse direction and disengages from the transmission assembly 3, and the end of the inner support clamping assembly 6 radially expands outward to clamp the round tube internally; the external rotational power drives the transmission assembly 3, the floating assembly 7, and the inner support clamping assembly 6 to rotate through the belt assembly 9, and the round tube rotates to facilitate operations such as angle adjustment and detection on the round tube. After the operation, the round tube can also be docked and sent back to the moving part via the inner support clamping assembly 6.
[0056] The utility model can realize floating buffering by the floating component, effectively avoiding collision or damage, externalizing the inner support unlocking power to the inner support clamping component, simplifying the structure, and effectively improving and ensuring the smoothness and reliability of adjustment and docking between the floating clamping rotating mechanism and the external component, and has good practicality.
