[0042] To enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Exemplarily, as Figure 1 , Figure 2 and Figure 3 shown, a connector 100 includes a housing 110, a first rotatable movable body 120, a second rotatable movable body 130, at least one first centering transmission mechanism 140, at least one second centering transmission mechanism 150, at least one first centering member 160, and at least one second centering member 170.

[0044] Exemplarily, as Figure 1 shown, the housing 110 is provided with a connection cavity 111 penetrating in its longitudinal direction. The first rotatable movable body 120 is rotatably provided at a first end of the housing 110 along its longitudinal direction, and the second rotatable movable body 130 is rotatably provided at a second end of the housing 110 along its longitudinal direction. That is, asFigure 1 As shown, the first rotatable movable body 120 can be arranged at the left end of the housing 110, and the second rotatable movable body 130 can be arranged at the right end of the housing 110. Of course, in addition to this, the positions of the first rotatable movable body 120 and the second rotatable movable body 130 on the housing 110 can also be swapped, and this embodiment does not limit this.

[0045] Exemplarily, as Figure 1 shown, each of the first pair of centering transmission mechanisms 140 is arranged on the circumferential side wall of the housing 110 and is respectively in transmission connection with the first rotatable movable body 120 and the corresponding first pair of centering members 160, so as to drive the first pair of centering members 160 to move radially along the connection cavity 111 under the drive of the first rotatable movable body 120. That is to say, as Figure 1 shown, by controlling the rotation of the first rotatable movable body 120, this process can be automatically driven by means of a motor or an electric machine, or can also be manually operated by a user, etc. The rotating first rotatable movable body 120 drives the first pair of centering transmission mechanisms 140 to rotate, so as to drive the first pair of centering members 160 to move linearly, and further enable the first pair of centering members 160 to move radially along the connection cavity 111. For example, move inwards or outwards radially along the connection cavity 111, etc.

[0046] Exemplarily, as Figure 1 shown, each of the second pair of centering transmission mechanisms 150 is arranged on the circumferential side wall of the housing 110 and is respectively in transmission connection with the second rotatable movable body 130 and the corresponding second pair of centering members 170, so as to drive the second pair of centering members 170 to move radially along the connection cavity 111 under the drive of the second rotatable movable body 130. The process of the second rotatable movable body 130 driving the second pair of centering members 170 to move is similar to that of the first rotatable movable body 120, and will not be elaborated here.

[0047] When specifically applying the connector 100 of this embodiment, two workpieces with regular shapes and the same or different outer dimensions, namely a first workpiece and a second workpiece, such as a circular tube, a solid rod, a square tube, a square rod, a multi-faceted hollow rod or a solid rod, etc., can be used. Insert the first workpiece into the connection cavity 111 from one end of the housing 110, and insert the second workpiece into the connection cavity 111 from the other end of the housing 110. Then, drive the first centering transmission mechanism 140 by the first rotatable movable body 120 to drive the first centering members 160 to move radially inward until each first centering member 160 abuts and fixes against the first workpiece. And drive the second centering transmission mechanism 150 by the second rotatable movable body 130 to drive the second centering members 170 to move radially until each second centering member 160 abuts and fixes against the second workpiece. In this way, both the first workpiece and the second workpiece are clamped and fixed in the connector 100, and the cross-sectional profiles of the first workpiece and the second workpiece can be centered.

[0048] The connector of this embodiment can achieve the purpose of quickly clamping and quickly centering two different workpieces by using the provided first rotatable movable body, second rotatable movable body, first centering transmission mechanism, second centering transmission mechanism, first centering members and second centering members, that is, the central axes of two different workpieces can be quickly collinear.

[0049] Exemplarily, as Figure 1 and Figure 4 shown, a first tooth portion 121 is provided on the first rotatable movable body 120, and the first centering member 160 is a first centering screw. The first centering transmission mechanism 140 includes a first transmission gear set, the first transmission gear set meshes with the first tooth portion 121, the first centering screw is disposed in the first transmission gear set and is screwed thereto, and one end of the first centering screw is fixedly connected to the housing 110. A second tooth portion (not shown in the figure, and the structure of this second tooth portion is similar to that of the first tooth portion 121) is provided on the second rotatable movable body 130, and the second centering member 170 is a second centering screw. The second centering transmission mechanism 150 includes a second transmission gear set, the second transmission gear set meshes with the second tooth portion, the second centering screw is disposed in the second transmission gear set and is screwed thereto, and one end of the second centering screw is fixedly connected to the housing 110.

[0050] Exemplarily, as Figure 1 and Figure 4As shown, the first transmission gear set includes a first main transmission gear 141, a first driven gear 142, and a first intermediate gear 143. The first main transmission gear 141 is provided with a first internal thread (not shown in the figure). The first main transmission gear 141 meshes with the first tooth portion 121, and the first internal thread is screwed with one of the first centering screws. The first driven transmission gear 142 is provided with a second internal thread (not shown in the figure), and the second internal thread is screwed with the other first centering screw. The first intermediate gear 143 is disposed between the first main transmission gear 141 and the first driven transmission gear 142, and meshes with the first main transmission gear 141 and the first driven transmission gear 142 respectively.

[0051] Specifically, as Figure 1 and Figure 4 shown, in this embodiment, the first rotatable movable body 120 can be controlled to rotate. The first tooth portion 121 on the first rotatable movable body 120 meshes with the first main transmission gear 141, so that the first main transmission gear 141 can be driven to rotate. The first main transmission gear 141 meshes with the first intermediate gear 143, so that the first intermediate gear 143 can be driven to rotate (however, the rotation direction of the first intermediate gear 143 is opposite to that of the first main transmission gear 141). The second driven transmission gear 142 meshes with the first intermediate gear 143, so that the second driven transmission gear 142 can be driven to rotate (the rotation direction of the second driven transmission gear 142 is the same as that of the first main transmission gear 141). Two different centering screws are respectively inserted into the first main transmission gear 141 and the first driven transmission gear 142. One end of the centering screw is fixed to the housing 110, so that the centering screw can be prevented from rotating inside the gear, and further the rotation of the gear can be converted into the linear movement of the centering screw, that is, the centering screw can be made to move radially along the connection cavity 111.

[0052] It should be noted that the first transmission gear set is not limited to including only one first driven transmission gear and one first intermediate gear. The first transmission gear set may include other odd numbers of gears. For example, the first transmission gear set includes one first main transmission gear, two first driven transmission gears, two first intermediate gears, etc. As long as it is ensured that an intermediate gear is provided between two adjacent first transmission gears (the first main transmission gear and the first driven transmission gear, or the first driven transmission gear and the first driven transmission gear), and at the same time, internal threads are provided on the two adjacent first transmission gears for screwing with the centering screws, so as to achieve quick clamping and centering.

[0053] Exemplarily, as Figure 1As shown, the second transmission gear set includes a second main transmission gear 151, a second driven transmission gear 152, and a second intermediate gear 153. The second main transmission gear 151 is provided with a third internal thread (not shown in the figure). The second main transmission gear 151 meshes with the second tooth portion, and the third internal thread is screwed with one of the second centering screws. The second driven transmission gear 152 is provided with a fourth internal thread (not shown in the figure), and the fourth internal thread is screwed with the other second centering screw. The second intermediate gear 153 is disposed between the adjacent second main transmission gear 151 and the second driven transmission gear 152, and meshes with the second main transmission gear 151 and the second driven transmission gear 152 respectively. The specific transmission mode of the second transmission gear set and the description of the number of gears included are similar to those of the first transmission gear set, and are not elaborated in this embodiment.

[0054] Exemplarily, as Figure 1 , 4 and Figure 5 shown, the first tooth portion 121 may be a bevel gear. The first main transmission gear 141 is provided with a first bevel gear 141a and a first straight gear 141b. The first bevel gear 141a meshes with the first tooth portion 121, and the first straight gear 141b meshes with the first intermediate gear 143. The second tooth portion 131 may also be a bevel gear. The second main transmission gear 151 is provided with a second bevel gear (not marked in the figure, similar to the first bevel gear 141a) and a second straight gear (not marked in the figure, similar to the first straight gear 141b). The second bevel gear meshes with the second tooth portion, and the second straight gear meshes with the second intermediate gear 153.

[0055] Exemplarily, as Figure 1 shown, the connector 100 further includes at least one cover plate 180. The cover plate 180 is connected to the housing 110, and one ends of the corresponding first centering screws and the second centering screws are fixedly connected to the cover plate 180 respectively.

[0056] Exemplarily, as Figure 1 shown, a plurality of long columnar bodies 181 are provided on a side of the cover plate 180 facing the housing 110. One ends of the first centering screws and the second centering screws are both provided with non-circular holes, and the non-circular holes are sleeved outside the corresponding long columnar bodies 181. The non-circular holes can be, for example, square holes or special-shaped holes, etc. The non-circular holes cooperate with the long columnar bodies 181 on the cover plate 180, so that the centering screws cannot rotate.

[0057] Exemplarily, as Figure 1 shown, the connector 100 includes a plurality of first centering transmission mechanisms 140 and a plurality of second centering transmission mechanisms 150. In Figure 1Among them, the connector 100 includes three first centering transmission mechanisms 140 and three second centering transmission mechanisms 150, but this embodiment is not limited thereto. The multiple first centering transmission mechanisms 140 are equidistantly arranged on the circumferential side wall of the housing 110. The multiple second centering transmission mechanisms 150 are equidistantly arranged on the circumferential side wall of the housing 110.

[0058] Exemplarily, as Figure 1 shown, the connector 100 further includes a first gland 190 and a second gland 200. The first gland 190 is located on the side of the first rotatable body 120 away from the housing 110, and the first gland 190 is detachably connected to the housing 110. For example, the first gland 190 can be screwed to the housing 110, etc. The second gland 200 is located on the side of the second rotatable body 130 away from the housing 110, and the second gland 200 is detachably connected to the housing 110.

[0059] Exemplarily, as Figure 1 shown, the connector 100 further includes a first outer diameter indicating assembly 210 and a second outer diameter indicating assembly (not marked in the figure, the same as the first outer diameter indicating assembly 210). The first outer diameter indicating assembly 210 is used to indicate the outer diameter size of the workpiece inserted into the connection cavity 111 via the first rotatable body 120. The second outer diameter indicating assembly is used to indicate the outer diameter size of the workpiece inserted into the connection cavity 111 via the second rotatable body 130.

[0060] Specifically, as Figure 2 , Figure 6 and Figure 7 shown, the first outer diameter indicating assembly 210 includes a first scale 211 and a first indicating icon 212. The first scale 211 is arranged on the first rotatable body 120, and the first indicating icon 212 is arranged on the first gland 190. The second outer diameter indicating assembly includes a second scale and a second indicating icon. The second scale is arranged on the second rotatable body 130, and the second indicating icon is arranged on the second gland 200.
