Description

Technical Field

[0001] This utility model relates to the technical field of coupling connection structure, specifically a coupling connection structure. Background Technology

[0002] In the transmission connection of the glue applicator roller, the connection between the coupling and the universal joint usually adopts a traditional structure: the bolt holes of the coupling are machined by drilling and tapping, and double-ended bolts are used with nuts for fixing during installation. When the glue applicator roller is replaced and the universal joint needs to be reinstalled, due to the narrow gap at the bolt of the drive shaft, the universal joint flange and the coupling cannot be aligned in one go. The nut needs to be tightened gradually around the circumference. That is, every time the nut is tightened a little, the flange and the coupling are partially in contact. This operation is repeated until they are completely in contact before the nut can be tightened in place.

[0003] This connection method has obvious limitations: the installation process requires multiple tightening steps, which is cumbersome and time-consuming. It not only increases the intensity of manual labor, but also affects the continuous operation efficiency of the equipment due to the long replacement time, making it difficult to meet the needs of the production line for rapid roller change. Therefore, a connection structure for the coupling is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a connection structure for a coupling that can solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention proposes a coupling connection structure comprising a connecting shaft and a connecting sleeve shaft, wherein the connecting shaft and the connecting sleeve shaft are connected by a connecting assembly, the connecting assembly comprising:

[0006] A positioning shaft, on the outer wall of which a rotating component is rotatably connected, and on the outer wall of which a screw is fixedly connected;

[0007] A fixing block, which is used to limit the movement of the screw;

[0008] A limiting groove is formed on the outer wall of the rotating component, and the limiting groove is matched with a limiting rod.

[0009] Preferably, the outer wall of the connecting shaft has multiple sets of through grooves, and the multiple sets of through grooves are arranged in a circular array around the central axis of the connecting shaft.

[0010] Preferably, both ends of the positioning shaft and the limiting rod are welded in the through groove, and the fixing block is fixedly connected in the through groove. The fixing block is a magnet used to hold the screw and keep the screw in a horizontal position.

[0011] Preferably, the connecting components are provided in multiple sets, and the number of sets of connecting components is the same as the number of sets of through slots. The multiple sets of connecting components are arranged in a circular array around the central axis of the connecting shaft.

[0012] Preferably, the outer wall of the connecting shaft has a ring array of multiple positioning protrusions.

[0013] Preferably, the outer wall of the connecting sleeve shaft has multiple sets of straight grooves, and the inner wall of the connecting sleeve shaft has multiple sets of positioning grooves. The positioning grooves match the positioning protrusions. By using the straight grooves, the position of the connecting shaft and the connecting sleeve shaft after connection can be adjusted, which facilitates the subsequent connection of the connecting sleeve shaft with other structures. By using the positioning protrusions and positioning grooves, the connecting shaft and the connecting sleeve shaft can be stably connected.

[0014] Preferably, the diameter of the screw is smaller than the diameter of the straight groove. After the screw rotates 90 degrees and moves out of the straight groove, the screw is locked by rotating the nut.

[0015] This utility model provides a connection structure for a coupling. It has the following advantages:

[0016] (1) The connection structure of this coupling achieves quick docking between the coupling and the universal joint through the use of the connecting components, the cooperation of the positioning shaft, the rotating parts and the screw. During installation, the positioning protrusion and the positioning groove are precisely engaged to ensure the initial positioning of the connecting shaft and the connecting sleeve shaft. The screw can rotate around the positioning shaft and smoothly pass through the straight groove of the connecting sleeve shaft. There is no need to tighten it step by step multiple times. Just rotate the screw ninety degrees to move it out of the straight groove and then rotate the nut to lock it. This eliminates the tedious steps of the traditional circumferential step-by-step fitting, greatly shortens the replacement time and reduces the intensity of manual labor.

[0017] (2) The connection structure of the coupling restricts radial displacement through the interlocking structure of the positioning protrusion and the positioning groove. With the locking of the screw and nut, it ensures that the connecting shaft and the connecting sleeve shaft are stably fitted. At the same time, the straight groove can flexibly adjust the position after connection to adapt to the installation requirements under different working conditions. This not only ensures the structural reliability during transmission, but also improves the adaptability and operational flexibility of the equipment. Attached Figure Description

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model proposes a connection structure for a coupling, including a connecting shaft 1 and a connecting sleeve shaft 2. The connecting shaft 1 and the connecting sleeve shaft 2 are connected by a connecting component 3. When connecting the connecting shaft 1 and the connecting sleeve shaft 2, the end of the connecting shaft 1 is first aligned with the port of the connecting sleeve shaft 2. The initial docking is completed through the cooperation of the connecting component 3. Then, the two are fixedly connected through the locking action of the connecting component 3.

[0029] In this embodiment of the invention, to enable rapid docking of the connecting shaft 1 and the connecting sleeve shaft 2, specifically, multiple sets of through grooves 101 are formed on the outer wall of the connecting shaft 1, and these through grooves 101 are arranged in a circular array around the central axis of the connecting shaft 1. Multiple sets of positioning protrusions 102 are arranged in a circular array on the outer wall of the connecting shaft 1. Multiple sets of straight slots 21 are formed on the outer wall of the connecting sleeve shaft 2, and multiple sets of positioning grooves 22 are formed on the inner wall of the connecting sleeve shaft 2. The positioning grooves 22 match the positioning protrusions 102. During the docking operation, the operator holds the connecting sleeve shaft 2, aligning the positioning grooves 22 on the inner wall of the connecting sleeve shaft 2 with the positioning protrusions 102 on the outer wall of the connecting shaft 1, and then... The connecting sleeve shaft 2 is pushed axially, causing the positioning protrusion 102 to gradually embed into the positioning groove 22 until the mating surfaces of the connecting shaft 1 and the connecting sleeve shaft 2 are in contact. During this process, the through groove 101 on the connecting shaft 1 and the straight groove 21 on the connecting sleeve shaft 2 will automatically align due to the guiding effect of the positioning protrusion 102 and the positioning groove 22. Through the matching design of the positioning protrusion 102 and the positioning groove 22, the connecting shaft 1 and the connecting sleeve shaft 2 are quickly positioned, avoiding misalignment adjustments during docking and significantly shortening the docking time. The automatic alignment of the through groove 101 and the straight groove 21 provides convenience for the subsequent fixing operation of the connecting component 3, ensuring the efficiency and accuracy of the docking process.

[0030] Furthermore, to achieve the fixation of the connecting shaft 1 and the connecting sleeve shaft 2 after connection, the connecting assembly 3 specifically includes a positioning shaft 31, a fixing block 34, and a limiting groove 35. A rotating component 32 is rotatably connected to the outer wall of the positioning shaft 31, and a screw 33 is fixedly connected to the outer wall of the rotating component 32. The fixing block 34 is used to limit the screw 33. The limiting groove 35 is formed on the outer wall of the rotating component 32 and matches the limiting rod 36. Both ends of the positioning shaft 31 and the limiting rod 36 are welded in the through groove 101. The fixing block 34 is fixedly connected in the through groove 101. The fixing block 34 is a magnet used to hold the screw 33, so that the screw 33 is in a horizontal position. The diameter of the screw 33 is smaller than that of the straight groove 21. After the screw 33 rotates 90 degrees and moves out of the straight groove 21, the screw 33 is locked by rotating the nut. After the docking is completed, the screw 33 is rotated to drive the rotating part 32 to rotate around the positioning shaft 31. At this time, the limiting groove 35 slides along the limiting rod 36 until the screw 33 rotates 90 degrees and moves out of the straight groove 21 completely. The limiting rod 36 is inserted into the end of the limiting groove 35 to achieve angle limiting. Finally, the nut is tightened on the screw 33 so that the nut fits tightly against the outer wall of the connecting sleeve shaft 2 to complete the fixation. There is no need to tighten it step by step multiple times. Just rotate the screw 33 90 degrees and move it out of the straight groove 21, and then rotate the nut to lock it. This eliminates the tedious steps of traditional circumferential step-by-step fitting, greatly shortens the replacement time, and reduces the intensity of manual labor.

[0031] Furthermore, multiple sets of connecting components 3 are provided, and the number of sets of connecting components 3 is the same as the number of sets of through grooves 101. Multiple sets of connecting components 3 are arranged in a circular array around the central axis of the connecting shaft 1. The multiple sets of circular array connecting components 3 can make the force on the connecting shaft 1 and the connecting sleeve shaft 2 evenly distributed, avoiding component deformation or damage caused by excessive local stress, and improving the overall load-bearing capacity and service life of the coupling.

[0032] In use, first hold the connecting sleeve shaft 2 and align the positioning groove 22 on the inner wall of the connecting sleeve shaft 2 with the positioning protrusion 102 on the outer wall of the connecting shaft 1. Then push the connecting sleeve shaft 2 axially so that the positioning protrusion 102 gradually embeds into the positioning groove 22 until the mating surfaces of the connecting shaft 1 and the connecting sleeve shaft 2 are in contact. During this process, the through groove 101 on the connecting shaft 1 and the straight groove 21 on the connecting sleeve shaft 2 will automatically align due to the guiding effect of the positioning protrusion 102 and the positioning groove 22. After the docking is completed, rotate the screw 33 to drive the rotating part 32 to rotate around the positioning shaft 31. At this time, the limiting groove 35 slides along the limiting rod 36 until the screw 33 rotates 90 degrees and completely moves out of the straight groove 21. The limiting rod 36 is inserted into the end of the limiting groove 35 to achieve angle limiting. Finally, tighten the nut on the screw 33 so that the nut is tightly fitted with the outer wall of the connecting sleeve shaft 2 to complete the fixing.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
