TECHNICAL FIELD

[0001] The utility model relates to the technical field of combined rotary table, in particular to a combined rotary table for multi-head machining center. BACKGROUND

[0002] Multi-head machining center is usually configured with combined rotary table to improve machining efficiency. The combined rotary table of multi-head machining center is a machine tool accessory capable of completing multiple station machining tasks in one working cycle. It is usually installed on a workbench and enables workpieces to be processed by different tools at different stations through rotation and positioning.

[0003] The prior art disclosed in Chinese utility model patent CN221658709U proposes a machining rotary table for numerical control machining center. The rotary table is connected with five jaw mechanisms and a cam mechanism through a slot in the cam. The chuck is connected with the rotary table through a screw thread. The cam mechanism is fixedly connected with the workbench and clamped with the chuck. The jaw mechanism automatically clamps and releases the workpiece along the slot in the cam, realizing multi-station automatic clamping and releasing.

[0004] However, the above-mentioned existing combined rotary table cannot adjust the angle between each jaw structure and the plane of the rotary table, so that the main shaft of the different cooperating machining center cannot perform multi-angle processing on the clamped workpiece, and the processing limitation is large. UTILITY MODEL CONTENT

[0005] To solve the above technical problems, the utility model provides a combined rotary table for multi-head machining center, which can perform multi-angle processing on workpieces, reduce the processing limitation and has good practicability.

[0006] This utility model discloses a combined rotary table for a multi-head machining center, comprising a mounting base, a turntable bearing, and a rotary table. The turntable bearing is horizontally and concentrically mounted on the mounting base, and the rotary table is concentrically mounted on the rotating end of the turntable bearing. It also includes multiple inner bearing seats, multiple outer bearing seats, multiple tilting tables, a first bevel gear, a first servo motor, and multiple second bevel gears. The multiple inner bearing seats are circumferentially and evenly mounted in the middle of the upper end face of the rotary table, and the multiple outer bearing seats are circumferentially and evenly mounted on the outer side of the upper end face of the rotary table. The multiple tilting tables are respectively located between the multiple inner bearing seats and the multiple outer bearing seats. The two ends of the multiple tilting tables are rotatably connected to the multiple rotary table and the multiple outer bearing seats via rotating shafts. The inner ends of each of the multiple tilting tables are concentrically mounted with a first bevel gear. Servo motor one is installed at the center of the upper end face of the turntable. The output shaft of servo motor one is concentrically mounted with bevel gear two, which meshes with multiple bevel gears one. The mounting base is installed on the worktable of the multi-head machining center. Multiple workpieces are clamped on the clamping components of multiple tilting tables. The turntable rotates to transfer multiple workpieces to the spindle of the machining center for processing. Servo motor one drives bevel gear two to rotate, and bevel gear two meshes with multiple bevel gears one to drive multiple tilting tables to rotate around their axis, thereby adjusting the tilt angle between multiple workpieces on multiple tilting tables and the turntable. This allows for multi-angle processing in conjunction with the spindle of the multi-head machining center, enabling efficient processing of the side of the workpiece, reducing processing limitations, and improving practicality.

[0007] Preferably, it also includes a second servo motor, a drive gear, and a gear disk. The second servo motor is mounted on a mounting base, and the drive gear is concentrically mounted on the output shaft of the second servo motor. The gear disk is concentrically mounted on the lower end face of the turntable, and the drive gear meshes with the gear disk. The second servo motor drives the drive gear to rotate, and the meshing of the drive gear and the gear disk drive the turntable to rotate. This technology is mature, can be programmed for automatic control, and has good practicality.

[0008] Preferably, the assembly also includes multiple slide rails, multiple slide tables, multiple optical axes, and multiple linear motor bodies. Slide rails are installed on each of the multiple tilting tables, and the multiple slide tables are slidably mounted on the multiple slide rails. The multiple optical axes are respectively mounted on the sides of the multiple tilting tables, and the multiple linear motor bodies are respectively slidably mounted on the multiple optical axes and respectively mounted on the side walls of the multiple slide tables. Workpieces are clamped on each of the multiple slide tables, and the multiple linear motor bodies move along the multiple optical axes, thereby driving the multiple slide tables to move along the multiple slide rails, thereby adjusting the position of the multiple workpieces and cooperating with the spindle to process the workpieces.

[0009] Preferably, it also includes multiple mounting slots, multiple clamping plates one and multiple clamping plates two. Multiple mounting slots are installed on multiple slides. The lower part of multiple clamping plates one and multiple clamping plates two is provided with slide rails that match the multiple mounting slots. Multiple clamping plates one and multiple clamping plates two are respectively installed on multiple mounting slots. Clamping plates one and two are arranged opposite to each other on the slides. Clamping plates one and two move along multiple mounting slots to adjust the distance between clamping plates one and two, thereby clamping workpieces of different widths, which is practical.

[0010] Preferably, it also includes multiple horizontal clamping slots, with horizontal horizontal clamping slots provided on the opposing surfaces of clamping plate one and clamping plate two, and the two horizontal clamping slots on clamping plate one and clamping plate two are arranged opposite to each other; the two horizontal clamping slots on the opposing surfaces of clamping plate one and clamping plate two can be used to clamp horizontally placed round tubes and cylindrical workpieces, improving the versatility of clamping.

The pressure rod is slidably inserted into the empty seat of the tilting table, with one end of the pressure rod limiting and pressing the inner end of the support rod. One end of the spring is connected to the tilting table, and the other end of the spring is connected to the pressure rod. The spring force pushes the pressure rod towards the support rod; after the workpiece is processed, pull the pressure rod to disengage one end from the support rod, thus releasing the inner end of the support rod from its limit. Turn the handle to rotate the inner end of the support rod upward, causing the guide chute to lift the workpiece out of clamping plates one and two, and allowing the workpiece to slide out of the tilting table along the guide chute for unloading. After unloading is completed, release the handle, and the spring force of the torsion spring will flatten and reset the support rod. Release the pressure rod, and the spring force will reset the pressure rod, causing the pressure rod to press down the inner end of the support rod to improve unloading efficiency.
