They are widely used in various transmission systems that require precise control. For example, this device is widely used in precision machining machine tools, aerospace industry, semiconductor equipment, printing machinery, food packaging, automation industry, industrial robots, medical inspection, precision testing instruments and other fields.

[0003] After a servo motor reducer has been running for a long time, its output shaft may wear out or even break due to continuous load and operation. Due to the precise internal structure and numerous components of the reducer, simply replacing the output shaft usually requires completely disassembling the entire reducer from the original mechanical system. This process is not only technically difficult, but also extremely time-consuming and labor-intensive. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing embodiments of the present invention, cross-sectional views of device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0025] Reference Figure 1-Figure 3 , which is an embodiment of the present invention, provides a servo motor reducer with a replaceable shaft, including a main unit 100, a moving unit 200 and a replacement unit 300.

[0026] The main unit 100 includes a device body 101 and a fixing base 102 that matches the device body 101. The fixing base 102 has mounting holes 103 at each of its four corners. The device body 101 is mounted to a designated location through the mounting holes 103 on the fixing base 102.

[0027] When the cam 310 is in the unlocking state, the cam 310 is in the unlocking state, and the cam 310 is in the unlocking state, so that the cam 310 can be unlocked and the cam 310 can be unlocked. After that, the driven shaft 302 is rotated in the opposite direction so that the slider 310 is withdrawn from the positioning groove 306 and returned to the sliding groove 305. Finally, the driven shaft 302 can be replaced by gently pulling out the driven shaft 302 along the axial direction. The entire replacement process does not require complicated tools, and the operation is smooth and efficient, which greatly improves the maintenance convenience and flexibility of the equipment.

[0028] The positioning structure includes an active cavity 308 symmetrically opened on one side of the card slot 304, and the inner cavities of the two sets of active cavities 308 are symmetrically installed with telescopic springs 309, and the other end of the telescopic spring 309 is fixedly installed with a limit block 307. The limit block 307 and the active cavity 308 are slidably connected. When the slider 310 enters the slide groove 305, it will continuously squeeze the limit block 307 until the limit block 307 moves out of the slide groove 305. At the same time, during the movement of the limit block 307, the telescopic spring 309 will be continuously squeezed. When the slider 310 rotates into the positioning groove 306, the squeezed telescopic spring 309 is rebounded, so that the limit block 307 returns to its original position, restricting the slider 310 in the positioning groove 306, thereby completing the positioning of the driven shaft 302.

[0029] The mobile unit 200 includes a base 201 installed at the bottom of the device body 101. Rollers 202 are installed at the four corners of the bottom of the base 201. When the device body 101 is too large, the position of the device body 101 can be moved through the base 201 and the rollers 202.

[0030] A fixing groove is provided at the top of the base 201 , and the fixing groove is engaged with the bottom of the device body 101 , and the assembly of the device body 101 and the base 201 is completed through the fixing groove.

[0031] When the slider 310 rotates into the positioning groove 306 , the side wall of the slider 310 fits tightly against the side wall of the limit block 307 , ensuring that the slider 310 does not move when in the inner cavity of the positioning groove 306 , thereby preventing the driven shaft 302 from being affected.

[0032] A limiting plate is provided on one side of the limiting block 307 close to the movable cavity 308 , and the limiting plate is slidably connected to the movable cavity 308 , and the limiting plate limits the range of movement of the limiting block 307 .

[0033] During use, the two sets of sliders 310 on the driven shaft 302 are accurately aligned and inserted into the slide groove 305 of the connecting sleeve 301. As the sliders 310 go deeper, they temporarily push the positioning structure in the slide groove 305 inward until it moves out of the inner cavity of the slide groove 305. The driven shaft 302 is rotated so that the sliders 310 originally located in the slide groove 305 are smoothly transferred into the positioning groove 306 on the connecting sleeve. At this time, the positioning structure automatically resets, tightly restricting the movement of the sliders 310, thereby achieving a stable limit on the driven shaft 302 and ensuring The output shaft 303 of the device can effectively drive the driven shaft 302 to rotate through the connecting sleeve 301. When the driven shaft 302 needs to be replaced, press the positioning structure, cancel the limit on the slider 310, rotate the driven shaft 302, and then rotate the driven shaft 302 in the opposite direction to make the slider 310 return from the positioning groove 306 to the slide groove 305. Finally, just gently pull out the driven shaft 302 along the axial direction to complete the replacement. The entire replacement process does not require complicated tools, and the operation is smooth and efficient, which greatly improves the maintenance convenience and flexibility of the equipment.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
