[0003] According to its transmission and indexing form, the indexing plate can be divided into worm pair indexing plate, disk indexing plate, hole disk indexing plate, slot disk indexing plate, end gear disk indexing plate and other indexing plates (including inductive indexing plate and grating indexing plate). According to its function, it can be divided into universal indexing plate, semi-universal indexing plate, and equal indexing plate. According to its structural form, there are vertical and horizontal indexing plates, tiltable indexing plates, and cantilever indexing plates. As a general-purpose machine tool accessory, the structure of the indexing plate is mainly composed of a clamping part, an indexing and positioning part, and a transmission part.

The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0019] The traditional indexing plate can adjust the angle of the workpiece fixed on it, but it cannot change its overall angle. This requires the staff to adjust the tool angle when tilting processing is required.

[0020] In view of this, the utility model provides a dividing chuck for a CNC machine tool, which can more conveniently change the different angles of a workpiece through the cooperation of a base plate, a cross plate, a top table, a bottom table, an adjusting device and an adjusting device. Therefore, when the workpiece is tilted, the staff does not need to re-align the tool due to adjusting the angle of the tool, which can greatly reduce the work intensity of the staff and improve work efficiency.

The dividing chuck for a numerically controlled machine tool also includes: an adjustment device 2, which is installed above the bottom plate 1; an adjustment device 3, which is arranged inside the bottom platform 6; a limit device 4, which is installed inside the bottom platform 6; the adjustment device 2 includes: an electric push rod 201, the model of the electric push rod 201 is TU-700, which is detachably connected to the top of the bottom plate 1; a first slider 20 2, is slidably engaged with the inner wall of the bottom plate 1, and is detachably connected to the output end of the electric push rod 201; the second slide block 203 is installed at the end of the first slide block 202, and is slidably engaged with the inner wall of the cross plate 5; wherein the adjustment device 2 can change the overall angle of the indexing chuck for the CNC machine tool, the adjustment device 3 can adjust the angle of the clamped workpiece, the limit device 4 can tighten and limit the top platform 7 and the bottom platform 6, and the electric push rod 201 can drive the second slide block 203 to move along the inner wall of the cross plate 5 through the first slide block 202, thereby changing the angle between the cross plate 5 and the bottom plate 1;

[0022] In the specific implementation process, it is worth pointing out that a scale is processed on the lower side of the outer wall of the top platform 7. Through the scale corresponding to the pointer 10, the staff can accurately know the angle between the top platform 7 and the bottom platform 6. The electric push rod 201 can drive the second slider 203 to move through the first slider 202. As the position of the second slider 203 changes, the angle between the bottom plate 1 and the horizontal plate 5 can be changed.

The limit device 4 can tighten the top platform 7 and the bottom platform 6 to limit the position, thereby ensuring the stability of the workpiece during processing;

[0025] Specifically, when using the indexing chuck for CNC machine tools, the staff uses the first mounting seat 8 and the second mounting seat 9 to install the fixture on the top of the top platform 7 by bolting, and then installs the workpiece to be processed on the fixture. At this time, the staff changes the processing angle of the workpiece through the adjustment device 2 and the adjustment device 3. When the adjustment is completed, the limit device 4 can be used for limiting, and then the processing operation can be carried out. When it is necessary to change the overall angle of the indexing chuck for CNC machine tools, the staff turns on the external power supply of the electric push rod 201. At this time, the electric push rod 201 can drive the first slider 202 to slide along the inner wall of the base plate 1, and the first slider 202 drives the second slider 203 to slide along the inner wall of the cross plate 5. As the position of the second slider 203 changes, the angle between the cross plate 5 and the base plate 1 can be changed, and then the overall angle of the indexing chuck for CNC machine tools can be changed.

[0027] In the specific implementation process, it is worth pointing out that twisting the rotating rod 304 can drive the second bevel gear 301 to rotate, and as the second bevel gear 301 rotates, the first bevel gear 302 can be driven to rotate, and at this time, the angle between the top platform 7 and the bottom platform 6 can be changed through the vertical column 303;

[0028] Specifically, based on the above-mentioned embodiments 1 and 2, when the angle of the workpiece needs to be changed, the staff twists the rotating rod 304, and the rotating rod 304 can drive the second bevel gear 301 to rotate, and then drive the first bevel gear 302 to rotate. At this time, the first bevel gear 302 can drive the top platform 7 to rotate through the vertical column 303, thereby changing the angle of the workpiece.
