[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] Please see Figures 1-3 To address the problems in the prior art, this utility model provides a machining device 1 for rotating shafts, including a lathe body 11, a machining fixture 12, a first tool holder assembly 13, and a second tool holder assembly 14. The machining fixture 12 is rotatably mounted on the lathe body 11 to clamp the rotating shaft. The first tool holder assembly 13 includes a support plate 131, a fixed base 132, a sliding base 133, a turret 134, and a pressure plate 135. The support plate 131 is mounted on one side of the lathe body 11 of the machining fixture 12. The fixed base 132 is mounted on the support plate 131. The sliding base 133 is slidably connected to the fixed base 132 and can slide along a first direction. The turret 134 is slidably connected to the sliding base 133 and can slide along a second direction. The pressure plate 135 is L-shaped, with one side mounted on the lathe body 11 and the other side in contact with the sliding base 133. The height of the turret 134 is the same as the center height of the machining fixture 12.

[0027] The lathe body 11 is provided with a tool holder slide rail 111, and the second tool holder assembly 14 is slidably connected to the tool holder slide rail 111 to drive the cutting tool to perform cutting on the rotating shaft.

[0028] By rotatably mounting the machining fixture 12 onto the lathe body 11, the machining fixture 12 clamps the rotating shaft and drives the rotating shaft to rotate synchronously. By sliding the second tool holder assembly 14 onto the slide rail 1215, the second tool holder assembly 14 drives the cutting tool to perform turning machining on the rotating shaft clamped by the machining fixture 12. When the diameter of the rotating shaft clamped by the machining fixture 12 is too large, the movement of the second tool holder assembly 14 cannot meet the turning machining requirements of the rotating shaft. In this case, the rotating shaft can be turned by operating the first tool holder assembly 13.

[0029] Specifically, the first tool holder assembly 13 is mounted on one side of the lathe body 11 via a support plate 131, and a fixed base 132 and a sliding base 133 are provided on the support plate 131 so that the sliding base 133 can move along the first direction on the fixed base 132. Since the turret 134 is slidably connected to the sliding base 133 and can move along the second direction, the tool can be driven to move in the first and second directions under the movement of the sliding base 133 and the turret 134. Thus, the turret 134 can drive the tool to perform turning machining on the large-diameter rotating shaft, thereby satisfying the turning machining of the large-diameter rotating shaft without having to install the large-diameter rotating shaft on different types of lathes for turning machining, thus improving machining efficiency.

[0030] In the above embodiments, when the sliding base 133 moves along the first direction, it drives the turret 134 to move along the diameter direction of the rotating shaft, thereby allowing the cutting tool to move closer to or further away from the outer cylindrical surface of the rotating shaft, facilitating turning of the outer cylindrical surface of the rotating shaft. When the turret 134 moves along the second direction, it drives the cutting tool to move along the length direction of the rotating shaft, thereby allowing the cutting tool to move along the length direction of the rotating shaft, facilitating turning of the outer cylindrical surface at different positions of the rotating shaft, thus satisfying the turning needs of large-diameter rotating shafts and improving machining efficiency.

[0031] The structural design allows the turret 134 to slide flexibly in two directions, enabling precise adjustment of the tool position to adapt to the machining needs of different parts and shapes, thus improving machining flexibility and precision. The pressure plate 135 enhances the stability of the sliding base 133 during sliding, preventing it from shifting or shaking during machining, further ensuring the accuracy of the tool position. The second tool holder assembly 14 is slidably connected to the tool holder slide rail 111, facilitating the cutting of the rotating shaft by the cutting tool. Furthermore, the position and angle of the cutting tool can be adjusted according to machining process requirements, enabling diverse cutting operations and improving the equipment's versatility and machining efficiency.

[0032] In an embodiment of this utility model, the sliding base 133 includes a horizontal section 1331 and a vertical section 1332. The bottom surface of the horizontal section 1331 is slidably connected to the fixed base 132, and the top surface of the horizontal section 1331 is slidably connected to the turret 134. The pressure plate 135 includes a horizontal plate 1351 and a vertical plate 1352. The horizontal plate 1351 is installed on the top surface of the lathe body 11, and the vertical section 1332 is fixed to one side of the horizontal section 1331. One side of the vertical section 1332 is in contact with the lathe body 11, and the other side is in contact with the vertical plate 1352. When the sliding base 133 slides along the first direction, it is limited by the pressure plate 135, thereby making the sliding of the sliding base 133 more stable and improving the machining accuracy of the lathe tool.

[0033] In an embodiment of this utility model, a first slider is provided on the bottom surface of the horizontal section 1331, and a first groove is provided on the top surface of the fixed base 132. The first slider is slidably connected to the first groove, so as to increase the straightness of the sliding base 133 during the sliding process under the cooperation of the first slider and the first groove, reduce the shaking and offset during the sliding process, and thus improve the machining quality of the turning tool on the rotating shaft.

[0034] In an embodiment of this utility model, a second sliding groove is provided on the top surface of the horizontal section 1331, and a second slider is provided on the bottom surface of the turret 134. The second slider is slidably connected to the second sliding groove, so as to increase the straightness of the turret 134 during the sliding process with the cooperation of the second slider and the second sliding groove, reduce the shaking and offset during the sliding process, and thus improve the machining quality of the cutting tool on the rotating shaft.

[0035] In an embodiment of this utility model, the support plate 131 includes a base plate 1311 and two stiffening plates 1312. The base plate 1311 is installed on the side of the lathe body 11, and the two stiffening plates 1312 are respectively fixed on both sides of the base plate 1311 to support the fixed base 132. After the base plate 1311 is installed on the lathe body 11, the stiffening plates 1312 on both sides provide support for the fixed base 132, thereby allowing the turret 134 to be installed on the fixed base 132 through the sliding base 133, and enabling the turret 134 to perform turning operations on the rotating shaft. At the same time, by removing the support plate 131 from the lathe body 11, the first tool holder assembly 13 can be disassembled from the lathe body 11 to avoid the first tool holder assembly 13 affecting the function of the second tool holder assembly 14.

[0036] In an embodiment of this utility model, the first tool holder assembly 13 further includes a first driving member 136 and a lead screw. A protruding connecting block is provided at the bottom of the horizontal section 1331. A connecting groove for sliding of the connecting block is provided on the fixed base 132. The lead screw passes through the connecting block and is rotatably connected to both ends of the connecting groove. The first driving member 136 is fixed to the side of the fixed base 132 and fixedly connected to the lead screw so that the horizontal section 1331 can be moved along the first direction by the lead screw, thereby causing the turret 134 to drive the cutting tool to move along the first direction, so that the cutting tool can perform turning machining on the rotating shaft.

[0037] In an embodiment of this utility model, the first tool holder assembly 13 further includes a second driving member 137. One end of the second driving member 137 is mounted on the vertical section 1332, and the other end is fixedly connected to the tool turret 134 to drive the tool turret 134 to move along the second direction, thereby causing the tool turret 134 to drive the cutting tool to move along the second direction, so that the cutting tool can perform turning machining on the rotating shaft.

[0038] Please see Figures 4-5In an embodiment of this utility model, the processing fixture 12 includes a chuck assembly 121 and an extension assembly 122. The chuck assembly 121 includes a chuck body 1211, an adjustment disk, and three jaws 1212. The three jaws 1212 are arranged in an array along the circumferential direction of the chuck body 1211. The adjustment disk is located inside the chuck body 1211, and a spiral track is provided on the surface of the adjustment disk. Each of the three jaws 1212 is provided with connecting teeth that mesh with the spiral track. The chuck body 1211 is provided with a connecting part that connects to the adjustment disk.

[0039] The expansion component 122 includes an adjusting claw 1221, a connecting rod 1222, and an adjusting rod 1223. The number of adjusting claws 1221 is adapted to the number of claws 1212. A first step 1213 and a second step 1214 are provided on the claws 1212. A slide rail 1215 is provided on the first step 1213. The adjusting claw 1221 is slidably connected to the slide rail 1215. The connecting rod 1222 passes through the adjusting claw and is inserted into the second step 1214. The adjusting tube passes through the connecting rod 1222 and is threadedly connected to the second step 1214. The end face of the adjusting claw 1221 is higher than the end face of the second step 1214.

[0040] By engaging the connecting teeth on the chuck 1212 with the spiral track on the adjusting plate, the adjusting plate can be rotated when the connecting part is rotated, thereby causing the adjusting plate to open or close the chuck 1212 to achieve the clamping action of rotating shafts of different diameters, and thus enabling the lathe to perform turning machining on the clamped rotating shafts.

[0041] The adjusting claw 1221 is inserted into the first step 1213 to mount it onto the chuck 1212. The connecting rod 1222 is inserted into the second step 1214, and the adjusting rod 1223 is threaded onto the second step 1214. Thus, the adjusting claw 1221 is fixed onto the chuck 1212 by the combined action of the connecting rod 1222 and the adjusting rod 1223. Since the end face height of the adjusting claw 1221 is higher than the end face height of the second step 1214, and the adjusting claw 1221 is mounted on the first step 1213, the adjusting claw 1221... Under the action of the chuck, the clamping range of the jaw 1212 is increased. Therefore, when clamping a large-diameter rotating shaft, the position of the jaw 1212 can be adjusted so that the jaw 1212 opens and drives the adjusting jaw 1221 to open synchronously until the position of the adjusting jaw 1221 can clamp the large-diameter rotating shaft. Then, the rotating shaft is placed at the center position of the three adjusting jaws 1221, and the position of the jaw 1212 is adjusted again so that the jaw 1212 clamps and drives the adjusting jaw 1221 to clamp the rotating shaft. This makes it easier for the lathe to perform turning machining on the rotating shaft and improves the clamping range of the chuck.
