Description

Technical Field

[0001] This utility model relates to the field of machine tool accessories technology, and in particular to a high-precision single-drive BC servo rotary table device. Background Technology

[0002] BC servo rotary table refers to a precision CNC rotary table that uses a high-performance servo drive (such as Elmo's BC2 series) with the series code "BC" as its core control component. It is a high-end mechatronics device that combines a precision mechanical rotary table with high-performance BC series servo drive technology. It is used in CNC machine tools and can fix the workpiece by the servo rotary table and control the workpiece to rotate in a set direction and speed to adjust the machining position and direction of the workpiece.

[0003] The existing servo turntable can be equipped with fixtures of different structures for clamping and positioning the workpiece. However, for irregularly shaped workpieces, such as polygonal or curved workpieces, multiple sets of clamping plates are required to clamp the workpiece from multiple directions. During the clamping and unclamping process, the clamping plates in multiple directions need to be adjusted separately, which is cumbersome and not suitable for processing large batches of workpieces.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1: Please refer to Figures 1 to 7 :

[0029] This utility model proposes a high-precision single-drive BC servo turntable device, including: a turntable drive mechanism 1, a servo turntable 2 connected to the top of the rotating shaft of the turntable drive mechanism 1, a guide groove 201 formed on the upper surface of the servo turntable 2, the guide groove 201 having a "T" shaped cross-section, a groove end plate 202 fixedly connected to one end of the guide groove 201 near the center of the servo turntable 2, a clamping and pushing screw 3 provided inside the guide groove 201, the end of the clamping and pushing screw 3 being rotatably connected to the guide groove 201 via a bearing, a screw drive gear 301 fixedly connected to the outer end of the clamping and pushing screw 3, and a clamping slider 4 slidably connected inside the guide groove 201. The slider 4 passes through a slider through hole 401 with a circular hole structure. The slider 4 is connected to a transmission plate 6. The bottom of the transmission plate 6 has a spiral groove 602. The spiral groove 602 is an arc-shaped groove. The inner surface of the spiral groove 602 has a thread that is spirally connected to the external thread of the clamping push screw 3. The clamping push screw 3 slides through the slider through hole 401. When the slider 4 is docked with the transmission plate 6, the clamping push screw 3 rotates. Through the spiral transmission between the clamping push screw 3 and the spiral groove 602, the clamping slider 4 and the clamping block plate 5 are pushed to slide along the direction of the guide groove 201, so that the clamp connected to the clamping block plate 5 moves closer to or away from the workpiece.

[0030] In this embodiment, a slider insertion port 402 is provided on the side of the clamping slider 4 away from the turntable drive mechanism 1. Insertion plate slots 403 are provided on both sides of the top of the slider insertion port 402. The transmission plate 6 is inserted into the slider insertion port 402. Insertion plate flanges 601 are fixedly connected to the upper edges of both sides of the transmission plate 6. The insertion plate flanges 601 are tightly fitted to the insertion plate slots 403. The insertion plate flanges 601 and the insertion plate slots 403 are fixedly connected by screws. The screws fix the insertion plate flanges 601 and the insertion plate slots 403 together, so that the transmission plate 6 is fixedly installed in the clamping slider 4. If it is necessary to adjust the position of a single clamping slider 4 in the servo turntable 2, the screws in the transmission plate 6 are removed, and the transmission plate 6 is removed from the top of the clamping slider 4, so that the spiral groove 602 is separated from the clamping push screw 3. The position of the clamping slider 4 can be adjusted by sliding along the guide groove 201, so that the clamping slider 4 can be adjusted so that the clamping plates are distributed according to the outer edge contour of the workpiece.

[0031] In this embodiment, a clamping block plate 5 is fixedly connected to the top of the clamping slider 4. The clamping block plate 5 has screw holes, which can be used to install clamping plates of different models to adapt to workpieces of different shapes and materials.

[0032] In Example 2, based on Example 1, a linkage ring 7 is rotatably connected to the upper edge of the outer periphery of the servo turntable 2. The side of the linkage ring 7 facing the center of the servo turntable 2 has a hollow structure. The bottom surface of the cavity of the linkage ring 7 has a ring internal tooth 702, which meshes with the lead screw drive gear 301. The linkage ring 7 has an arc-shaped structure, and the two ends of the linkage ring 7 are respectively fixedly connected with ring lugs 701. Four adjacent linkage rings 7 are connected to the bolts end to end through the ring lugs 701 to form a closed ring structure. The four linkage rings 7 are assembled into a ring structure by the ring lugs 701 and the threaded connectors. The ring internal tooth 702 meshes with multiple lead screw drive gears 301 synchronously. During the rotation of the linkage ring 7, all the clamping push lead screws 3 can be driven to rotate synchronously to achieve the synchronous movement of all the clamping sliders 4.

[0033] The working principle of this embodiment is as follows: The workpiece to be processed is placed in the center of the servo turntable 2. The screws in the insert plate flange 601 are removed by tools, the transmission insert plate 6 is detached, and then the position of the clamping slider 4 is adjusted by sliding along the guide slide groove 201 so that the clamping plate connected to the clamping block plate 5 fits the surface of the workpiece. The adjustment of a single clamping slider 4 is achieved. The transmission insert plate 6 is then installed again in the slider socket 402 by screws. The position of all clamping sliders 4 is adjusted in this way so that the clamping plates are distributed according to the outer edge contour of the workpiece. When clamping the workpiece, the linkage ring 7 is rotated. The meshing connection between the internal teeth 702 of the ring and the lead screw drive gear 301 drives the clamping push lead screw 3 to rotate. The helical transmission between the clamping push lead screw 3 and the helical groove 602 pushes the clamping slider 4 and the transmission insert plate 6 to slide inside the guide slide groove 201, driving the multi-directional clamping plates to move synchronously, so as to achieve stable and rapid clamping of the workpiece.
