Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of equipment installation, in particular to a connecting structure. BACKGROUND
[0002] In automated production, sometimes multiple devices need to be connected to each other in order to precisely process or move materials to a predetermined station.
[0003] Currently, when the equipment needs to be repaired or moved due to a change of location, the devices need to be disconnected first. When the devices are reconnected, the pre-set position on one device needs to be aligned with the pre-set position on another device to ensure the accuracy of material transmission or processing. Therefore, the relative positions of the devices need to be constantly adjusted, which makes the operation of reconnecting the two devices time-consuming and needs to be improved. CONTENT OF THE UTILITY MODEL
[0004] Therefore, the present application provides a connecting structure which can shorten the time required for reconnecting two devices and thus improve the speed of reconnecting the two devices.
[0005] The embodiment of the present application provides a connecting structure, which comprises a first connecting piece, a second connecting piece, a positioning piece and a fixing piece. The first connecting piece is used for connecting a first device, the second connecting piece is used for connecting a second device, and the second connecting piece and the first connecting piece are sequentially arranged along a first direction. The positioning piece is connected to the first connecting piece, the second connecting piece is provided with a positioning groove, the positioning piece is inserted into the positioning groove, the positioning groove has a first positioning surface and a second positioning surface, the first positioning surface and the second positioning surface are sequentially arranged along a second direction, the second direction intersects the first direction, the first positioning surface is inclined relative to the first direction and the second direction, and the second positioning surface is inclined relative to the first positioning surface; the first positioning surface abuts against the positioning piece and stops the positioning piece along the first direction towards the first connecting piece, and the second positioning surface abuts against the positioning piece and stops the positioning piece along the second direction towards the first positioning surface. The fixing piece connects the first connecting piece and the second connecting piece, so that the positioning piece keeps abutting against the first positioning surface and the second positioning surface.
[0006] When initially connecting the first and second devices, the first and second connectors can be attached to the first and second devices respectively. Then, the positioning member abuts against the first and second positioning surfaces, and the fixing member is installed to connect the first and second connectors. The position of the first connector relative to the first device or the position of the second connector relative to the second device can be adjusted to align preset positions on the first and second devices. To separate the first and second devices, the fixing member can be removed. To precisely reconnect the first and second devices, the positioning member is inserted into the positioning groove, and the fixing member is installed. Operating the fixing member allows the first and second connectors to move closer together along a first direction. During this process, after the positioning member abuts against the first positioning surface, it slides along the first positioning surface and moves towards the second positioning surface until it abuts against the second positioning surface, completing the connection operation between the first and second connectors. This allows for a quick and precise reconnection of the first and second devices. The first positioning surface and the second positioning surface cooperate with each other to position and constrain the position of the positioning element along the first direction and the second direction, thereby enabling the preset position on the first device and the preset position on the second device to be quickly re-aligned, thereby shortening the time required to accurately reconnect the first device and the second device, and thus improving the speed of accurately reconnecting the first device and the second device.
[0007] In some embodiments of this application, the positioning member is provided with an arc-shaped abutment surface, which abuts against the first positioning surface and the second positioning surface.
[0008] The arc-shaped contact surface forms a line contact with the first and second positioning surfaces, which reduces the precision requirements for the positioning components and facilitates their machining. In use, two or more of these connection structures can be used to connect the first and second devices to restrict the rotation of each positioning component relative to its corresponding second connecting component.
[0009] In some embodiments of this application, the positioning member is provided with a first abutting surface and a second abutting surface, the first abutting surface is parallel to the first positioning surface and abuts against the first positioning surface, and the second abutting surface is parallel to the second positioning surface and abuts against the second positioning surface.
[0010] The first abutting surface is parallel to and abuts against the first positioning surface, and the second abutting surface is parallel to and abuts against the second positioning surface. This increases the contact area between the positioning member and the first and second positioning surfaces, thereby improving the stability of the positioning member relative to the second connecting member. It also facilitates the connection between the first and second devices through a single such connection structure.
[0011] In some embodiments of the present application, the first connecting piece is provided with a mounting groove, the mounting groove and the positioning groove are both provided in the third direction, the positioning piece can be respectively inserted into the mounting groove and the positioning groove in the third direction, the third direction is perpendicular to the first direction and the second direction, and the mounting groove can constrain the positioning piece in the first direction and the second direction.
[0012] When reconnecting the first device and the second device, the first connecting piece and the second connecting piece can be connected to each other and can move relative to each other in the first direction by the fixing piece, then the positioning piece is inserted into the mounting groove and the positioning groove in the third direction, and the first connecting piece and the second connecting piece are locked by the fixing piece, so that the inner wall of the mounting groove, the first positioning surface and the second positioning surface abut the positioning piece respectively, so that the first connecting piece and the second connecting piece are relatively fixed in the first direction and the second direction, and the first device and the second device are connected to each other and kept relatively fixed. The positioning piece is designed separately from the first connecting piece, which facilitates the replacement of different sizes of the positioning piece according to different distance requirements of the first device and the second device in the first direction.
[0013] In some embodiments of the present application, the connecting structure further comprises a limiting piece, the limiting piece is detachably connected with the first connecting piece or the second connecting piece, and the limiting piece abuts against the positioning piece and stops the positioning piece in the third direction towards the corresponding first device or second device.
[0014] The limiting piece can stop the positioning piece in the third direction to constrain the positioning piece in the position between the limiting piece and the corresponding first device or second device, thereby reducing the possibility of the positioning piece being separated from the mounting groove or the positioning groove, and improving the stability of the positioning piece fixed relative to the first connecting piece and the second connecting piece.
[0015] In some embodiments of the present application, the connecting structure further comprises a receiving piece, the receiving piece is connected with the first connecting piece or the second connecting piece, and the side of the positioning piece away from the limiting piece in the third direction abuts against the receiving piece.
[0016] The receiving piece is used for receiving the positioning piece and cooperating with the limiting piece to clamp the positioning piece, so that the positioning piece does not need to be supported by the first device or the second device, thereby improving the flexibility of the installation of the connecting structure.
[0017] In some embodiments of the present application, one of the first connecting piece and the second connecting piece is provided with a fixing through hole in the first direction, the other of the first connecting piece and the second connecting piece is provided with a fixing screw hole in the first direction, the fixing piece is a fixing screw, and the fixing screw is inserted into the fixing through hole and threadedly cooperates with the fixing screw hole.
[0018] The rotating fixing screw can make the first connecting member and the second connecting member approach each other in the first direction, so that the positioning member abuts against the first positioning surface and the second positioning surface, thereby fixing and connecting the first connecting member and the second connecting member to each other, and the structure is simple and the operation is convenient.
[0019] In some embodiments of the present application, the fixing through hole is a strip hole, and the length direction of the fixing through hole is arranged along the third direction, which is perpendicular to the first direction and the second direction.
[0020] The fixing through hole is a strip hole, which facilitates the adjustment of the relative position between the first connecting member and the second connecting member in the third direction, so as to facilitate the adjustment of the relative position between the first device and the second device in the third direction, thereby further facilitating the alignment of the preset position on the first device with the preset position on the second device.
[0021] In some embodiments of the present application, at least one of the first connecting member and the second connecting member is provided with a first connecting hole, the first connecting hole is a strip hole, the length direction of the first connecting hole is arranged along the first direction, and the connecting structure further comprises a first screw, which is inserted into the first connecting hole and used for connecting with the corresponding first device or second device.
[0022] In some embodiments of the present application, at least one of the first connecting member and the second connecting member is provided with a second connecting hole, the second connecting hole is a strip hole, the length direction of the second connecting hole is arranged along the second direction, and the connecting structure further comprises a second screw, which is inserted into the second connecting hole and used for connecting with the corresponding first device or second device.
[0023] The first screw can be inserted into the first connecting hole, the second screw can be inserted into the second connecting hole, and the first screw and the second screw are connected with the corresponding first device and second device. Since the first screw can move relative to the inner wall of the first connecting hole in the first direction, and the second screw can move relative to the inner wall of the second connecting hole in the second direction, the position of the corresponding first connecting member or second connecting member can be adjusted in the first direction and the second direction, so that the preset position on the first device and the preset position on the second device are aligned with each other after the first connecting member and the second connecting member are connected with each other.

[0037] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.
[0038] With reference to Figure 1 and Figure 2 , an embodiment of the present application provides a connecting structure 100, which comprises a first connecting piece 11, a second connecting piece 12, a positioning piece 13 and a fixing piece 14.
[0039] The second connecting piece 12 is spaced apart from the first connecting piece 11 along the first direction X, the first connecting piece 11 is used to connect with a first device (not shown in the figure), and the second connecting piece 12 is used to connect with a second device (not shown in the figure). The positioning piece 13 is connected to the first connecting piece 11, the second connecting piece 12 is provided with a positioning slot 121, the positioning piece 13 is inserted into the positioning slot 121, and the positioning slot 121 restricts the relative position between the positioning piece 13 and the second connecting piece 12 in the first direction X and the second direction Y, so that the preset position on the first device and the preset position on the second device are quickly aligned. The fixing piece 14 connects the first connecting piece 11 and the second connecting piece 12, so that the first connecting piece 11 and the second connecting piece 12 are relatively fixed, so that the first device and the second device are fixedly connected with each other. Wherein, the second direction Y intersects with the first direction X. In some embodiments, the second direction Y is perpendicular to the first direction X. For the convenience of description, the third direction Z is also defined, and the third direction Z is perpendicular to the first direction X and the second direction Y.
[0040] In some embodiments, one of the first connecting piece 11 and the second connecting piece 12 is provided with a fixed through hole 111 along the first direction X, the other of the first connecting piece 11 and the second connecting piece 12 is provided with a fixed screw hole 122 along the first direction X, the fixing piece 14 is a fixed screw 141, and the fixed screw 141 is inserted into the fixed through hole 111 and threadedly matched with the fixed screw hole 122. Exemplarily, the first connecting piece 11 is provided with the fixed through hole 111, and the second connecting piece 12 is provided with the fixed screw hole 122, and the fixed through hole 111 and the fixed screw hole 122 are respectively spaced apart by two along the second direction Y. The two fixed through holes 111 and the two fixed screw holes 122 are oppositely arranged on both sides of the positioning piece 13.
[0041] The fixed screw 141 is rotated, the first connecting piece 11 and the second connecting piece 12 are relatively close to each other in the first direction X, so that the positioning piece 13 abuts against the inner wall of the positioning slot 121, thereby fixing the first connecting piece 11 and the second connecting piece 12 to be connected with each other, which is simple in structure and convenient to operate. In other embodiments, the first connecting piece 11 and the second connecting piece 12 are both provided with through holes, the fixed screw 141 is simultaneously inserted into the through holes of the first connecting piece 11 and the second connecting piece 12, and the fixing piece 14 further includes a fixed nut, which is threadedly connected with the fixed screw 141, so as to connect the first connecting piece 11 and the second connecting piece 12 with each other. In other embodiments, the fixing piece 14 can also be other structural pieces capable of restricting the relative position between the first connecting piece 11 and the second connecting piece 12 in the first direction X.
[0042] In some embodiments, the fixing through hole 111 is a strip-shaped hole, and the length direction of the fixing through hole 111 is arranged along the third direction Z. The fixing screw 141 can be moved relative to the inner wall of the fixing through hole 111 along the third direction Z, so that the relative position between the first connecting piece 11 and the second connecting piece 12 can be adjusted in the third direction Z, so as to facilitate the adjustment of the relative position between the first device and the second device in the third direction Z.
[0043] Exemplarily, when the first device and the second device are connected for the first time, the preset position on the first device and the preset position on the second device can be aligned first; the first connecting piece 11 and the second connecting piece 12 are connected to each other through the positioning piece 13 and the fixing piece 14, and then the first connecting piece 11 is connected with the first device and the second connecting piece 12 is connected with the second device. In this way, when the fixing piece 14 is disassembled, the first device and the second device can be separated from each other; after the first connecting piece 11 and the second connecting piece 12 are connected to each other through the fixing piece 14 and the positioning piece 13 again, the preset position on the first device and the preset position on the second device can be quickly aligned again.
[0044] In some embodiments, at least one of the first connecting piece 11 and the second connecting piece 12 is provided with a first connecting hole 123, and the first connecting hole 123 is a strip-shaped hole, and the length direction of the first connecting hole 123 is arranged along the first direction X. In some embodiments, at least one of the first connecting piece 11 and the second connecting piece 12 is provided with a second connecting hole 112, and the second connecting hole 112 is a strip-shaped hole, and the length direction of the second connecting hole 112 is arranged along the second direction Y. Exemplarily, the first connecting piece 11 is provided with the second connecting hole 112, and the second connecting piece 12 is provided with the first connecting hole 123.
[0045] The connecting structure 100 further comprises a first screw 15 which is inserted into the first connecting hole 123 and used for connecting with the second device. The first screw 15 can be moved relative to the inner wall of the first connecting hole 123 along the first direction X, and the position of the corresponding second connecting piece 12 relative to the second device can be adjusted in the first direction X. The connecting structure 100 further comprises a second screw 16 which is inserted into the second connecting hole 112 and used for connecting with the first device. The second screw 16 can be moved relative to the inner wall of the second connecting hole 112 along the second direction Y, and the position of the corresponding first connecting piece 11 relative to the first device can be adjusted in the second direction Y. In some embodiments, the first connecting hole 123 and the second connecting hole 112 are both arranged through along the third direction Z. In other embodiments, the first connecting hole 123 and / or the second connecting hole 112 can be arranged through along the second direction Y. In other embodiments, the first connecting hole 123 and / or the second connecting hole 112 can also be arranged through along other directions, as long as the first screw 15 and the second screw 16 can be installed.
[0046] By adjusting the position of the first connecting member 11 relative to the first device and the position of the second connecting member 12 relative to the second device, the relative position between the first device and the second device after the first connecting member 11 and the second connecting member 12 are connected can be adjusted so as to align the preset position on the first device with the preset position on the second device.
[0047] In some other embodiments, the first connecting member 11 and the second connecting member 12 can also be connected to the corresponding first device and second device by welding or other means respectively.
[0048] With reference to Figure 2 and Figure 3 In some embodiments, the positioning groove 121 has a first positioning surface 1211 and a second positioning surface 1212, which are arranged in sequence along the second direction Y, the first positioning surface 1211 is inclined relative to both the first direction X and the second direction Y, and the second positioning surface 1212 is inclined relative to the first positioning surface 1211 and the second direction Y. The first positioning surface 1211 abuts against the positioning member 13 and stops the positioning member 13 along the first direction X towards the first connecting member 11, and the second positioning surface 1212 abuts against the positioning member 13 and stops the positioning member 13 along the second direction Y towards the first positioning surface 1211. It can be understood that along the first direction X and towards the first connecting member 11, the distance between the first positioning surface 1211 and the second positioning surface 1212 along the second direction Y gradually increases, so that the first positioning surface 1211 and the second positioning surface 1212 form a "V" shape opening along the first direction X towards the first connecting member 11.
[0049] When the first connecting member 11 and the second connecting member 12 are moved towards each other along the first direction X by the fixing member 14, when the positioning member 13 abuts against one of the first positioning surface 1211 and the second positioning surface 1212, the positioning member 13 can slide along the corresponding first positioning surface 1211 or the second positioning surface 1212 and move towards the other one of the first positioning surface 1211 and the second positioning surface 1212 until the positioning member 13 abuts against the second positioning surface 1212, that is, the connection between the first connecting member 11 and the second connecting member 12 is completed. The relative inclination of the first positioning surface 1211 and the second positioning surface 1212 facilitates the automatic insertion of the positioning block between the first positioning surface 1211 and the second positioning surface 1212, thereby facilitating the rapid and accurate connection between the first device and the second device.
[0050] In some other embodiments, the second positioning surface 1212 can also be perpendicular to the second direction Y, that is, the second positioning surface 1212 is parallel to the first direction X. It can be understood that in order to be able to stop the positioning block in the direction towards the first positioning surface 1211, the second positioning surface 1212 cannot be parallel to the second direction Y.
[0051] In some embodiments, the positioning member 13 is provided with an arc-shaped abutting surface 131 abutting against the first positioning surface 1211 and the second positioning surface 1212. The arc-shaped abutting surface 131 forms a line contact with the first positioning surface 1211 and the second positioning surface 1212, which can reduce the requirement for the machining precision of the positioning member 13 and facilitate the machining of the positioning member 13. In use, two or more such connecting structures 100 can be used to connect the first device and the second device to limit the rotation of each positioning member 13 relative to the corresponding second connecting member 12. For example, the positioning member 13 can be provided in a cylindrical shape, and the cylindrical surface of the positioning member 13 forms the arc-shaped abutting surface 131 abutting against the first positioning surface 1211 and the second positioning surface 1212.
[0052] In some embodiments, the first connecting member 11 is provided with a mounting groove 113, and the mounting groove 113 and the positioning groove 121 are both provided in the third direction Z. The positioning member 13 can be inserted into the mounting groove 113 and the positioning groove 121 in the third direction Z, and the inner wall of the mounting groove 113 abuts against the positioning member 13 and stops the positioning member 13 in the first direction X toward the second connecting member 12. The positioning member 13 is designed in a separate manner from the first connecting member 11, and the positioning member 13 can be inserted into the mounting groove 113 and the positioning groove 121 in the third direction Z, which facilitates the replacement of positioning members 13 of different sizes according to the different distance requirements between the first device and the second device in the first direction X.
[0053] Referring to Figure 2 and Figure 4 In some embodiments, the mounting groove 113 has a first mounting surface 1131 and a second mounting surface 1132, which are sequentially arranged in the second direction Y. The first mounting surface 1131 is inclined relative to the first direction X and the second direction Y, and the second mounting surface 1132 is inclined relative to the first mounting surface 1131 and the second direction Y. The first mounting surface 1131 abuts against the positioning member 13 and stops the positioning member 13 in the first direction X toward the first connecting member 11, and the second mounting surface 1132 abuts against the positioning member 13 and stops the positioning member 13 in the second direction Y toward the first mounting surface 1131. For example, the first mounting surface 1131 and the second mounting surface 1132 form a “V” shape opening in the first direction X toward the second connecting member 12. It can be understood that, in some embodiments, the mounting groove 113 and the positioning groove 121 are both V-shaped grooves.
[0054] In other embodiments, the mounting groove 113 and / or the positioning groove 121 can also be profiled with the sidewall of the positioning member 13, and exemplarily, the mounting groove 113 and / or the positioning groove 121 are arc-shaped grooves; the inner wall of the corresponding mounting groove 113 or positioning groove 121 abuts against the sidewall of the positioning member 13 to constrain the positioning member 13 in the first direction X and the second direction Y.
[0055] In some embodiments, the connecting structure 100 further comprises a limiting member 17 and a receiving member 18, the limiting member 17 and the receiving member 18 are sequentially and spaced apart along the third direction Z. The receiving member 18 is connected with the first connecting member 11 and receives the positioning member 13, and the limiting member 17 is connected with the first connecting member 11 and abuts against the side of the positioning block away from the receiving member 18 along the third direction Z to stop the positioning member 13 along the third direction Z. The receiving member 18 is used to receive the positioning member 13 and cooperate with the limiting member 17 to clamp the positioning member 13, which can reduce the possibility of the positioning member 13 disengaging from the mounting groove 113 or the positioning groove 121, thereby improving the stability of the positioning member 13 fixed relative to the first connecting member 11 and the second connecting member 12. In some embodiments, the receiving member 18 is integrally formed with the first connecting member 11. Figure 4 The dashed line in the above figure is used to separate the receiving member 18 and the first connecting member 11, and in another embodiment, the dashed line used to separate the receiving member 18 and the first connecting member 11 can also be other shapes or located at other positions. In other embodiments, the receiving member 18 can also be connected with the first connecting member 11 through welding or through screws and the like.
[0056] In other embodiments, the limiting member 17 can also be connected with the second connecting member 12. In other embodiments, the receiving member 18 can also be connected with the second connecting member 12. In other embodiments, the receiving member 18 can be omitted, and the limiting member 17 is used to stop the positioning member 13 along the third direction Z towards the corresponding first device or second device, so that the limiting member 17 cooperates with the corresponding first device or second device to reduce the possibility of the positioning member 13 disengaging from the mounting groove 113 or the positioning groove 121.
[0057] Referring to Figure 1 and Figure 2 In some embodiments, the limiting member 17 comprises a first limiting screw 171, the positioning member 13 is provided with a positioning hole 132 along the third direction Z, and the receiving member 18 is provided with a limiting screw hole 181, the first limiting screw 171 is inserted into the positioning hole 132 and threadedly cooperates with the limiting screw hole 181, so that the head of the first limiting screw 171 abuts against the side of the positioning block away from the receiving block.
[0058] In some embodiments, the limiting member 17 further comprises a limiting plate 172 and a second limiting screw 173, the limiting plate 172 is arranged on the side of the positioning block away from the receiving member 18 along the third direction Z, and the limiting plate 172 is connected with the second connecting member 12 through the second limiting screw 173, so that the limiting plate 172 abuts against the side of the positioning block away from the receiving member 18. In other embodiments, the first limiting screw 171 can be omitted. In other embodiments, the limiting plate 172 can be connected with the first connecting member 11 through the second limiting screw 173.
[0059] In other embodiments, the positioning member 13 can be fixedly connected with the first connecting member 11. For example, the positioning member 13 is welded or integrally formed with the first connecting member 11.
[0060] Referring to Figure 5 In some embodiments, the positioning member 13 is provided with a first abutting surface 133 and a second abutting surface 134, the first abutting surface 133 is parallel to and abuts against the first positioning surface 1211, and the second abutting surface 134 is parallel to and abuts against the second positioning surface 1212. It can be understood that the first abutting surface 133 and the second abutting surface 134 are arranged at intervals along the second direction Y. For example, the positioning member 13 is inserted into one end of the positioning groove 121 and is substantially trapezoidal.
[0061] The first abutting surface 133 is parallel to and abuts against the first positioning surface 1211, and the second abutting surface 134 is parallel to and abuts against the second positioning surface 1212, which can increase the contact area between the positioning member 13 and the first positioning surface 1211 and the second positioning surface 1212, thereby improving the stability of the positioning member 13 relative to the second connecting member 12, and facilitating the connection between the first device and the second device through a single such connecting structure 100.
[0062] When the first device and the second device are separated and need to be reconnected, first, the first device and the second device are placed in predetermined positions respectively, then the fixing screw 141 is inserted into the fixing through hole 111 and screwed into the fixing screw hole 122, so that the first connecting member 11 and the second connecting member 12 are pre-fixed and have a certain interval between them, and then the positioning member 13 is inserted into the positioning groove 121, and the fixing screw 141 is tightened, so that the first connecting member 11 and the second connecting member 12 move relatively and drive the first device to move relative to the second device; when the positioning member 13 abuts against the first positioning surface 1211 and the second positioning surface 1212, the operation of reconnecting the first connecting member 11 and the second connecting member 12 is completed, and the operation of reconnecting the first device and the second device accurately is also completed quickly, without the need to adjust the relative position between the first device and the second device multiple times, which saves time and effort.
[0063] In addition, those skilled in the art will appreciate that the above-described embodiments are merely illustrative of the application and should not be construed as limiting the same. Numerous modifications and variations are possible in light of the above teachings without departing from the essence of the application.
