[0002] A cam-structured dividing turntable is a type of cam divider. Cam dividers are mechanisms that achieve intermittent motion and feature high indexing accuracy, smooth operation, large torque transmission, compact structure, small size, low noise, good high-speed performance, and long service life. The mechanical mechanism of a cam divider consists of an input shaft driven by a motor, a cam wheel, and an output shaft or flange combination. The turntable, used to mount workpieces and positioning fixtures, is mounted on the output shaft. Generally, a robotic arm is mounted on the turntable to assist in precise workpiece machining. The robotic arm is mainly positioned and fixed on the turntable using bolts, which makes the installation and removal of the robotic arm complex and inefficient.

[0003] Therefore, it is necessary to provide a new cam-structured rotary table manipulator to solve the above-mentioned technical problems. Utility Model Content

[0021] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a first three-dimensional structural schematic diagram of the cam-structured rotary manipulator of this utility model; Figure 2 A schematic diagram of the second three-dimensional structure of the cam-structured rotary manipulator provided by this utility model; Figure 3 This is a schematic diagram of the mounting base plate and positioning slider structure of the cam-structured dividing turntable robot of this utility model. The cam-structured dividing turntable robot includes: a support base 1, on which a cam divider 101 is fixedly mounted; a turntable body 3 is provided on the top of the cam divider 101; and a positioning mechanism and a workstation adjustment robot 4 are provided on the turntable body 3.

[0022] The positioning mechanism includes an adjusting screw 301, which is rotatably mounted on the turntable body 3. A handwheel 302 is fixedly connected to the top of the adjusting screw 301. A threaded sleeve 303 is threaded onto the adjusting screw 301. Multiple connecting rods 304 are fixedly mounted on the threaded sleeve 303. The multiple connecting rods 304 are arranged in a ring around the threaded sleeve 303. A connecting block 305 is fixedly mounted on one end of each connecting rod 304. Two positioning pins 306 are fixedly mounted on the connecting block 305.

[0023] The workstation adjustment robot 4 includes a mounting base plate 401, which is positioned above the turntable body 3. Two positioning holes are provided on the mounting base plate 401, and positioning pins 306 are adapted to these holes. A positioning slider 402 is fixedly mounted on the bottom of the mounting base plate 401. A mounting bracket 403 is fixedly mounted on the mounting base plate 401, and a servo motor 404 is fixedly mounted on the mounting bracket 403. A second adjusting screw 405 is rotatably mounted on the mounting base plate 401, with its top end fixedly connected to the output shaft of the servo motor 404. A lifting block 406 is provided on the mounting base plate 401, and the second adjusting screw 405 passes through and is threadedly connected to the lifting block 406. One end of the second adjusting screw 405 is fixedly connected to a workpiece processing plate 407.

[0024] like Figure 2 As shown, a stepper motor 2 is fixedly installed on the support base 1, and a worm gear 201 is fixedly connected to the output shaft of the stepper motor 2. A worm wheel 202 is fixedly installed on the input shaft of the cam divider 101, and the worm wheel 202 meshes with the worm gear 201.

[0025] When the stepper motor 2 is powered on, it drives the worm gear 201 to rotate, which in turn drives the worm wheel 202 to rotate. This causes the worm wheel 202 to rotate the input shaft of the cam divider 101. The cam wheel inside the cam divider 101 then rotates, causing the output shaft at the top of the cam divider 101 to rotate. The turntable body 3 is then driven to rotate synchronously through the rotation of the output shaft. When the stepper motor 2 is powered off, the worm gear 201 and the worm wheel 202 self-lock, facilitating the positioning of the turntable body 3 after it stops rotating.

[0026] like Figure 1 As shown, a protective shell is fixedly installed on the support base 1, and the worm 201 and worm wheel 202 are both located inside the protective shell;

[0027] By providing a protective shell, foreign objects are prevented from entering between the worm 201 and the worm wheel 202, thus affecting the meshing rotation.

[0028] like Figure 2 and Figure 3 As shown, the turntable body 3 has multiple positioning grooves, and the positioning slider 402 is adapted to the positioning grooves.

[0029] By providing a positioning groove on the turntable body 3, the station adjustment robot 4 can be accurately positioned and installed on the turntable body 3 via the positioning slider 402, thus improving the ease of installation and positioning of the station adjustment robot 4.

[0030] like Figure 1As shown, multiple limiting rods 307 are fixedly installed on the turntable body 3. The limiting rods 307 pass through the connecting rod 304 and are slidably connected to the connecting rod 304. An anti-detachment block is fixedly installed at the top of the limiting rod 307.

[0031] By setting a limit rod 307, when the adjusting screw 301 drives the screw sleeve 303 to raise and lower the connecting rod 304, the connecting rod 304 slides on the limit rod 307, which can limit the rotation of the connecting rod 304 and keep the connecting rod 304 stable during the raising and lowering process.

[0032] like Figure 2 As shown, two limiting blocks 5 are fixedly installed on the lifting block 406, and two limiting grooves are opened on the inner wall of the mounting bracket 403. The limiting blocks 5 are adapted to the limiting grooves.

[0033] When the lifting block 406 moves up and down, it causes the limiting block 5 to slide in the limiting groove, so that the limiting block 5 can limit the lifting block 406 and prevent the lifting block 406 from rotating during the lifting process.

[0034] The working principle of the cam-structured rotary table manipulator provided by this utility model is as follows:

[0035] First step: Insert the positioning slider 402 into the positioning groove on the turntable body 3, and then rotate the handwheel 302 by hand so that the handwheel 302 can drive the adjusting screw 301 to rotate. Then the adjusting screw 301 drives the screw sleeve 303 to rise and fall. The screw sleeve 303 drives the connecting rod 304 to move synchronously. Then the connecting rod 304 drives the connecting block 305 to move downward so that the positioning pins 306 at both ends of the connecting block 305 can be positioned in the positioning holes on the mounting base plate 401, thereby positioning and fixing the mounting base plate 401, making the installation and operation of the workstation adjustment robot 4 convenient.

[0036] The second step: The servo motor 404 is powered on and drives the adjusting screw 405 to rotate. Then the adjusting screw 405 drives the lifting block 406 to move up and down, so that the lifting block 406 can drive the workpiece processing plate 407 to adjust the position. Then the workpiece on the workpiece processing plate 407 can be adjusted to adjust the processing height according to the requirements.

[0037] The third step: The stepper motor 2 is powered on to drive the worm gear 201 to rotate, and then the worm gear 201 drives the worm wheel 202 to rotate, which in turn drives the input shaft of the cam divider 101 to rotate. This allows the top output shaft of the cam divider 101 to drive the turntable body 3 to rotate, which in turn drives the station adjustment robot 4 to rotate. This facilitates the linkage and cooperation between the cam divider 101 and the station adjustment robot 4, thereby improving the efficiency of workpiece processing.
