Description

Technical Field

[0001] The utility model relates to the technical field of flexible couplings, in particular to a flexible coupling for micro transmission. Background Art

[0002] A coupling is a device used to connect two shafts in different mechanisms so that they rotate together to transmit torque. Couplings are generally divided into rigid couplings and flexible couplings. Rigid couplings can transmit greater torque but have poor shock absorption and buffering performance. Flexible couplings have good shock absorption and buffering capabilities but are easily damaged under high torque working conditions.

[0003] When installing the existing flexible coupling for micro transmission, it is necessary to align it with the installation position and then fix it with bolts. It cannot be assisted in positioning during the installation process. When offset occurs, it will make it difficult to screw the bolts in for installation. In view of this, a flexible coupling for micro transmission is proposed. Utility Model Content

[0012] Preferably, the outer wall of the threaded rod is threadedly connected with an L-shaped threaded sleeve, and an L-shaped connecting rod is fixed to the bottom of the L-shaped threaded sleeve. A clamping plate is fixed to the end of the L-shaped connecting rod away from the L-shaped threaded sleeve. When the threaded hole on the connecting disk is aligned with the threaded hole of the mounting disk of the mounting part, the mounting disk and the connecting disk can be tightly fitted through the clamping plate, thereby preventing the other side from warping and deflecting when a bolt is installed in one threaded hole, which makes it inconvenient to install the bolt.

[0024] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a flexible coupling for micro transmission, including a coupling body 1, a connecting plate 2 is fixed to the side wall of the coupling body 1, and the coupling body 1 can be installed through the threaded hole by aligning the connecting plate 2 with the installation position. An annular circular groove 4 is opened on the outer wall of the coupling body 1, and an auxiliary mechanism 5 for facilitating connection is arranged on the connecting plate 2, and a clamping mechanism 6 is arranged on the auxiliary mechanism 5.

[0025] Specifically, the auxiliary mechanism 5 includes a slider 51, a groove 52, a moving block 53, a positioning block 55, a return spring 54, a rubber block 56, a connecting rod 57 and a rotating ring 58; the slider 51 is slidably mounted on the inner wall of the annular groove 4, a groove 52 is provided on the side of the slider 51 away from the coupling body 1, a moving block 53 is slidably mounted on the inner wall of the groove 52, a return spring 54 is fixed on the side of the moving block 53 away from the annular groove 4, and a return spring 54 is fixed on the inner wall of the groove 52 on the side away from the moving block 53. By setting the return spring 54, the moving block 53 can be In order to achieve the effect of resetting, a positioning block 55 is fixed on one side of the moving block 53 away from the reset spring 54. The positioning blocks 55 are provided with three groups, and the three groups of positioning blocks 55 are arranged in a circular array with the center point of the connecting disk 2. Then, when it is necessary to connect the coupling body 1 and the mounting portion, the connecting disk 2 drives the positioning block 55 to approach the mounting portion, so that the inclined surface of the positioning block 55 squeezes the mounting disk on the mounting portion, which causes the positioning block 55 to be subjected to the squeezing force, and the moving block 53 moves upward in the groove 52, compressing the reset spring 54. When the connecting disk 2 drives the card slot of the positioning block 55 to contact the mounting portion, the positioning block 55 is pressed against the mounting plate on the mounting portion. When aligning the mounting disk of the mounting part, because the reset spring 54 is in a compressed state, the three groups of positioning blocks 55 are close to each other to position the mounting disk on the mounting part, so that the connecting disk 2 on the coupling body 1 can be aligned with the mounting disk on the mounting part, thereby facilitating installation. The inner wall of the card slot of the positioning block 55 is fixed with multiple groups of rubber blocks 56 with equal distances. The rubber blocks 56 can squeeze the mounting disk on the mounting part. By setting the rubber blocks 56, the mounting disk on the mounting part can be prevented from being squeezed and scratched. A connecting rod 57 is fixed on the side of the slider 51 away from the moving block 53. The connecting rod 57 is far away from the moving block 53. A rotating ring 58 is fixed to one end of the slider 51. After the mounting disk on the mounting position is clamped and positioned by the positioning block 55, the slider 51 can be moved in the annular groove 4 by rotating the rotating ring 58. The positioning block 55 can drive the mounting disk on the mounting position to rotate, and then the threaded holes on the mounting disk on the mounting position can be adjusted to align with the threaded holes on the connecting disk 2, so as to facilitate the staff to connect with the bolts and prevent the mounting disk on the mounting position from being misaligned and offset with the connecting disk 2, thereby affecting the efficiency of the installation bolts.

[0026] Specifically, the clamping mechanism 6 includes a connecting groove 61, a threaded rod 62, a knob 63, an L-shaped threaded sleeve 64, an L-shaped connecting rod 65 and a clamping plate 66; the connecting groove 61 is provided on the positioning block 55, the inner wall of the connecting groove 61 is rotatably mounted with a threaded rod 62, the end point of the threaded rod 62 is fixed with a knob 63, the outer wall of the threaded rod 62 is threadedly connected with an L-shaped threaded sleeve 64, and then when the knob 63 is turned forward, the L-shaped threaded sleeve 64 can be moved closer to the connecting plate 2, and an L-shaped threaded sleeve 64 is fixed on one side close to the coupling body 1. The connecting rod 65, a clamping plate 66 is fixed at one end of the L-shaped connecting rod 65 away from the L-shaped threaded sleeve 64. When the L-shaped threaded sleeve 64 moves, the clamping plate 66 can be driven to move through the L-shaped connecting rod 65, so that the clamping plate 66 can squeeze the mounting disk on the mounting part stuck in the slot, so that the mounting disk on the mounting part fits tightly with the connecting disk 2, thereby facilitating the connection operation and preventing the other side from warping and deflecting when installing a bolt in a threaded hole, which makes it inconvenient to install the bolt.

[0027] Working principle: when it is necessary to install the coupling body 1 and the mounting disk of the mounting part, the connecting disk 2 drives the positioning block 55 to approach the mounting part, so that the inclined surface of the positioning block 55 squeezes the mounting disk on the mounting part, which will cause the positioning block 55 to be subjected to the extrusion force, and the moving block 53 will move upward in the groove 52 to compress the reset spring 54. When the connecting disk 2 drives the card slot of the positioning block 55 to align with the mounting disk of the mounting part, because the reset spring 54 is in a compressed state, the three groups of positioning blocks 55 approach each other to position the mounting disk on the mounting part, so that the connecting disk 2 on the coupling body 1 can be aligned with the mounting disk on the mounting part. After the mounting disk on the mounting part is clamped and positioned by the positioning block 55, the sliding block 51 can be moved in the annular groove 4 by rotating the rotating ring 58, and the mounting disk on the mounting part can be driven to rotate by the positioning block 55, so that the threaded hole on the mounting disk on the mounting part can be adjusted to align with the threaded hole on the connecting disk 2.

[0028] When the threaded holes are aligned, turning the knob 63 forward can make the L-shaped threaded sleeve 64 approach the connecting disk 2, which can drive the clamping plate 66 to move, so that the clamping plate 66 can squeeze the mounting disk on the mounting part stuck in the slot, so that the mounting disk on the mounting part fits tightly with the connecting disk 2, thereby facilitating the connection operation and preventing the other side from warping and offsetting when installing a bolt in a threaded hole, which makes it inconvenient to install the bolt.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
