Description

Technical Field

[0001] This utility model relates to the field of electromechanical parts technology, and more specifically, to a high-precision electromechanical fixed shaft. Background Technology

[0002] High-precision electromechanical motors are devices that convert or transmit electrical energy. Their main function is to convert mechanical energy into electrical energy for use. Based on the type of power source, motors can be classified into various types. During operation, the shaft-like parts between the rotating shaft and the geared motor mainly support transmission components, transmit torque, and bear loads. The fixed shaft is stationary, while rotating or sliding components can be mounted on it.

[0003] During use, existing fixed shafts are prone to wear due to the high-speed rotation between the shaft and the rotating parts. Most existing fixed shafts are integrally molded, making it difficult to quickly replace the shaft when wear occurs. The replaced shaft cannot guarantee the stability of use, which has certain drawbacks.

[0004] In view of this, we propose a high-precision electromechanical fixed shaft. Utility Model Content

[0025] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] A high-precision electromechanical fixed shaft includes a body 1, a fixed shaft 2 fixedly mounted on the outer side of the body 1, a mounting hole 3 penetrating the inner side of the fixed shaft 2, and a mounting shaft 5 movably mounted on the outer side of the fixed shaft 2. A connector 6 is fixedly mounted on the outer end of the mounting shaft 5, a threaded surface 9 is provided on the outer side of the connector 6, and a smooth surface 10 is provided on the outer part of the connector 6 outside the threaded surface 9. A connecting sleeve 4 is rotatably mounted on the outer side of the fixed shaft 2, a fixing ring 11 is fixedly mounted on the inner side of the connecting sleeve 4, two sets of limiting grooves 7 are provided on the outer side of the connector 6, and two sets of limiting blocks 8 that mate with the limiting grooves 7 are fixedly mounted on the inner side of the mounting hole 3. The limiting blocks 8 slide within the limiting grooves 7, and through the limiting cooperation between the limiting blocks 8 and the limiting grooves 7, the connector 6 cannot rotate within the mounting hole 3, thereby improving the stability of the mounting shaft 5 and preventing the mounting shaft 5 from slipping.

[0029] Specifically, the connector 6 is movably inserted into the mounting hole 3 and extends to the inside. The inner side of the retaining ring 11 is provided with an internal thread of the mating thread surface 9. The thread surface 9 is threaded to the internal thread. When installing the mounting shaft 5, by inserting the connector 6 into the inside of the mounting hole 3 and rotating the connecting sleeve 4, the connector 6 can be fixed by the retaining ring 11 on the inner side of the connecting sleeve 4. This ensures the installation stability of the connector 6 while improving the ease of installation and removal of the connector 6.

[0030] Furthermore, a fixing plate 21 is fixedly installed on the outside of the fixing shaft 2, and multiple sets of fixing blocks 12 are fixedly installed on the outside of the connecting sleeve 4. Fixing bolts 14 are movably installed on the outside of each set of fixing blocks 12. The fixing bolts 14 are threaded through the fixing blocks 12 and extend to the other side. Multiple sets of screw holes 13 for mating fixing bolts 14 are opened through the outside of the fixing plate 21. By screwing the fixing bolts 14 into the screw holes 13, the connecting sleeve 4 can be fixed, thereby further improving the installation stability of the connector 6 and ensuring the installation stability of the mounting shaft 5.

[0031] It is worth noting that protective pads are provided on both sides of the fixing block 12. The protective pads are made of soft material. The soft protective pads can increase the friction of the fixing block 12, making it easier for the operator to rotate the connecting sleeve 4 and improving the ease of rotation of the connecting sleeve 4.

[0032] It is worth noting that multiple sets of positioning rods 15 are fixedly installed on the outside of the connecting sleeve 4, and multiple sets of positioning holes 16 for docking positioning rods 15 are opened on the outside of the mounting shaft 5. When the connector 6 and the mounting shaft 5 are installed, the positioning rods 15 are movably inserted into the positioning holes 16, which can further improve the installation stability of the mounting shaft 5 and ensure the overall strength of the device.

[0033] In addition, an annular groove is provided on the outer side of the fixed shaft 2, and an annular block that mates with the annular groove is fixedly provided on the inner side of the connecting sleeve 4. The annular block is limited to rotate within the annular groove. By setting the annular quick-connect annular groove, the connecting sleeve 4 can be easily rotated in place, while ensuring the installation stability of the connecting sleeve 4.

[0034] Working principle: First, the mounting shaft 5 is connected to the shaft body. When the mounting shaft 5 wears out, the multiple sets of fixing bolts 14 are unscrewed from the screw holes 13. Then, the connecting sleeve 4 is rotated counterclockwise. When the connecting sleeve 4 is rotated, the connecting head 6 is driven to rotate through the fixing ring 11. Since the connecting head 6 is limited by the limiting groove 7 and the limiting block 8, it cannot rotate but moves outward in the mounting hole 3. When the connecting head 6 moves, it drives the mounting shaft 5 to move. As the connecting head 6 continues to move, when the threaded surface 9 on the outside of the connecting head 6 separates from the fixing ring 11 on the inside of the connecting sleeve 4, the connecting head 6 can be pulled out from the inside of the mounting hole 3. Then, the mounting shaft 5 can be quickly replaced.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
