[0021] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0022] This utility model provides a connecting structure for the broken end of a lead screw, which can solve the problem in related technologies where the scrapping of lead screws increases production costs and affects the normal production activities of enterprises.

[0023] See Figure 1As shown in the illustration, a lead screw fracture end connection structure is provided in this embodiment of the present invention for connecting the fracture point 2 of the lead screw end 1. It includes: a connecting body 3, sleeved on the outside of the lead screw end 1 and covering the fracture point 2; a first locking mechanism 4, installed at one end of the connecting body 3, which drives the connecting body 3 to abut against the outside of the lead screw end 1; and a second locking mechanism 5, installed at the other end of the connecting body 3, which also drives the connecting body 3 to abut against the outside of the lead screw end 1. By sleeved on the outside of the lead screw fracture point 2 and locking both ends of the connecting body 3 with the locking mechanisms, the broken lead screw can be connected. This saves time on disassembly, assembly, and purchase of lead screws, reduces lead screw purchase costs, and provides a simple and reliable structure that allows for rapid restoration of equipment use.

[0024] See Figure 2 As shown, in some embodiments, the connecting body 3 has a through hole 6 inside. The through hole 6 includes a first segment 61 and a second segment 62. The inner diameter of the second segment 62 is larger than the inner diameter of the first segment 61, so as to match the shape of the lead screw end 1. This allows the inner walls of the first segment 61 and the second segment 62 to fit snugly against the lead screw end 1, thus providing a better fixing effect.

[0025] See Figure 2 As shown, in some embodiments, the connecting body 3 is provided with a radially extending mounting hole 31, which is connected to the through hole 6. A bolt can be installed in the mounting hole 31, and the bolt passes through both the connecting body 3 and the lead screw end 1, which can further fix the broken part.

[0026] See Figure 2 As shown, in some embodiments, the portion of the connector 3 located in the first segment 61 is provided with a boss 32, and the mounting hole 31 is provided on the boss 32. By providing the boss 32, the strength of the mounting hole 31 position is increased, ensuring that bolts can be installed in the mounting hole 31 for fixation.

[0027] See Figure 2 As shown, in some embodiments, the boss 32 extends from the outside of the first segment 61 to the outside of the second segment 62, such that the thickness of the connecting body 3 outside the first segment 61 and the second segment 62 is small and approximately the same, which facilitates the use of a locking mechanism to drive the connecting body 3 to abut against the outside of the lead screw end 1.

[0028] See Figure 2As shown, in some embodiments, an inclined surface 33 is provided at the connection between the first segment 61 and the second segment 62. The inclined surface 33 slopes downward from the second segment 62 to the first segment 61. The angle between the inclined surface 33 and the second segment 62 is preferably 135°, which matches the shape of the lead screw end 1, so that the inclined surface 33 can abut against the lead screw end 1, reducing the shaking of the connection structure.

[0029] See Figure 2 As shown, in some embodiments, the inner wall of the second segment 62 is provided with a thread 34, which matches the structure and assembly position of the original lead screw locking nut. The thread 34 can be used to install the second segment 62 onto the lead screw end 1 to further enhance the fixing effect.

[0030] See Figure 1 As shown, in some embodiments, both the first locking mechanism 4 and the second locking mechanism 5 adopt locking discs. The locking discs include two semi-annular discs, each of which is provided with multiple bolt holes. By tightening the high-strength bolts passing through the discs, the two discs are pressed together. This pressing force causes the discs to expand radially, thereby tightly fitting the shaft surface and achieving a keyless connection.

[0031] See Figure 1 As shown, in some embodiments, the first locking mechanism 4 is installed outside the first segment 61, and the second locking mechanism 5 is installed outside the second segment 62. The diameter of the second locking mechanism 5 is larger than the diameter of the first locking mechanism 4, so as to match the diameter of different parts of the lead screw end 1.

[0032] See Figure 1 As shown, in some embodiments, a bearing 7 is installed on the connecting screw end 1, and the end of the connecting body 3 abuts against the inner ring fixing sleeve of the bearing 7, further increasing the stability of the connection structure and reducing shaking.

[0033] Before assembly, use a dial indicator to ensure that the axis of the input end is within 0.01mm coaxial with the axis of the lead screw.

[0034] When installing the connector 3, remove the original locking nut, put the second locking mechanism 5 on the connector 3, screw the connector 3 onto the thread of the lead screw, and tighten the inner ring fixing sleeve of the bearing. Then, tighten the locking screw on the second locking mechanism 5 with a torque wrench to complete the connection of the lead screw end. Next, put the first locking mechanism 4 on the connector 3, insert the input shaft to the appropriate position, and tighten the locking screw on the first locking mechanism 4 with a torque wrench to complete the connection of the power input end.

[0035] This utility model provides a connecting structure for the broken end of a lead screw. By adding a reliable connector to the broken end of the lead screw, the connector utilizes the original structure of the lead screw and can restore the transmission function of the broken lead screw without disassembling and processing it. This reliable method of quick restoration of use is not a stopgap measure but can achieve long-term normal use. It can save the time spent on disassembling and assembling the lead screw, the time spent waiting to purchase a new lead screw, and the cost of purchasing a lead screw. The structure is simple and reliable, and can restore the transmission function of the mechanical transmission system quickly and at low cost.

[0036] To manufacture connector 3, it is necessary to measure the length of the broken original lead screw, the thread type and specifications of the lead screw used to lock the support bearing, and the form and size of the input end.
