[0027] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment 1

[0029] In the prior art, the indexing disk is only applicable to workpieces with a fixed size not exceeding its diameter. When the size of the workpiece exceeds the diameter of the indexing disk, effective fixation cannot be achieved. To solve this problem, users usually need to replace a larger indexing disk, which not only increases the cost but also makes the operation complicated.

[0030] Therefore, in order to solve the problem that the diameter of the existing indexing disk is fixed and it is difficult to fix workpieces of multiple sizes, and to achieve the function of expanding the installation end face of the indexing disk and improving the versatility, the present utility model discloses an extended - surface clamping indexing disk. Refer to Figures 1-4 , which includes a fixed disk 1 for placing the workpiece to be processed, a fixed rod 2 provided on the fixed disk 1 for fixing the workpiece to be processed, and an extension rod for expanding the installation end face of the indexing disk, including a connecting rod 3 and a supporting rod 4. Among them, the connecting rod 3 is connected between the fixed rod 2 and the supporting rod 4. Fixing holes 6 for fixing the workpiece to be processed are provided on the top surfaces of the fixed rod 2, the connecting rod 3, and the supporting rod 4. The supporting rod 4 includes a tray 5 and an inner rod 9. Among them, two trays 5 are respectively clamped on both sides of the inner rod 9. A through groove 10 is provided on the inner rod 9, and a bolt 7 is provided on the tray 5 and is inserted into the through groove 10. The bolt 7 is used for the tray 5 to make a reciprocating horizontal movement on the inner rod 9 along the through groove 10;

[0031] By connecting the extension rod to the fixed rod 2, the effect of expanding the installation end face of the fixed disk 1 can be achieved. Specifically, threaded holes are provided at both ends of the connecting rod 3, and threaded posts 8 corresponding to the threaded holes are provided at both ends of the supporting rod 4 and at the end of the fixed rod 2 facing the connecting rod 3;

[0032] Exemplarily, when it is necessary to fix a workpiece with a size exceeding that between the fixed disks 1, the user can first connect the threaded hole at one end of the connecting rod 3 to the threaded post 8 at one end of the fixed rod 2. By adding the connecting rod 3, the installation end face of the fixed disk 1 can be enlarged, so as to adapt to workpieces of larger sizes.

[0033] Next, the user can connect the supporting rod 4 to the other end of the connecting rod 3 through the threaded post 8. The supporting rod 4 can increase the contact area between the extension rod and the workpiece, so that the extension rod can be more stable when receiving the workpiece. Specifically, a nut 11 for fixing the supporting plate 5 is provided at the bottom of the bolt 7;

[0034] Exemplarily, by stretching the two supporting plates 5 outwards and then fixing the supporting plates 5 through the nut 11, the two supporting plates 5 can be extended outwards on both sides with the fixing hole 6 as the center, further expanding the contact area between the extension rod and the workpiece and improving the fixing effect on the workpiece.

[0035] In one embodiment, the staff can stack a plurality of extension rods on each other according to the size of the workpiece and connect them to the fixed rod 2.

[0036] In this embodiment, in order to prevent the supporting plate 5 from blocking the fixing hole 6 when it is closed, semi-circular rings corresponding to the fixing hole 6 are provided on one side of each of the two supporting plates 5 facing the fixing hole 6. Through this setting, it can be ensured that when the supporting plate 5 is closed, the fixing hole 6 can still be smoothly penetrated by the bolt 7, so as to realize the fixing of the workpiece. At the same time, when the supporting plate 5 does not need to be unfolded, the two semi-circular rings will form a circular ring to play a role in clamping the bolt 7, thereby improving the stability of the bolt 7.

[0037] In this embodiment, in order to prevent the situation of friction jamming between the bolt 7 and the through groove 10 when the supporting plate 5 moves along the through groove 10, a rubber sleeve is provided on the inner wall surface of the through groove 10, and the bolt 7 is in contact with the rubber sleeve. Through this setting, the bolt 7 will not directly rub against the through groove 10, further improving the service life of the device.

[0038] In one embodiment, six fixed rods 2 are provided on the fixed disk 1, and the included angle between two adjacent fixed rods 2 is sixty degrees. It can be understood that the fixed disk 1 is disc-shaped. Through this setting, it helps to evenly support the workpiece to be processed on the fixed disk 1, so that the processing process is more stable and accurate.

[0039] In summary, through the setting of the extension rod, the installation end face of the fixed disk 1 is effectively enlarged, so that the dividing head can adapt to workpieces of larger sizes, thereby improving the versatility of the dividing head.

[0040] Example Two

[0041] Based on Example One, in order to process the workpiece fixed on the fixed disk 1 at multiple angles, refer to Figure 1 , the present utility model further includes a rotating assembly for rotating the fixed disk 1. Specifically, a base is provided at the bottom of the fixed disk 1, and a rotating assembly for rotating the fixed disk 1 is provided between the fixed disk 1 and the base;

[0042] In this embodiment, by rotating the fixed disk 1, the fixed workpiece can be processed at different angles, thereby meeting the requirements of multi-angle processing. The rotating assembly may include a motor and a transmission mechanism. The motor is connected to the fixed disk 1 through the transmission mechanism, enabling the fixed disk 1 to rotate. The transmission mechanism can be a gear transmission, a belt transmission, or other suitable transmission methods to ensure smooth rotation and sufficient torque.

[0043] Furthermore, in order to improve the operation convenience, the rotating assembly can also be connected to an external control panel. The control panel is provided with operation buttons such as start, stop, and speed regulation, as well as a display screen for displaying information such as the current rotation speed and rotation angle. The user can control the rotation state of the fixed disk 1 through the control panel to achieve precise processing of the workpiece.

[0044] In addition, in order to ensure the stability and durability of the rotating assembly, a shock absorption device is provided between the base and the rotating assembly. The shock absorption device can be a spring, a rubber pad, or other shock absorption materials to absorb the vibration generated during rotation and reduce the impact on the equipment and the workpiece.

[0045] In summary, by providing a rotating assembly at the bottom of the fixed disk 1, the indexing disk has the ability to process the workpiece at multiple angles, making the entire processing process more efficient and precise, and improving the production efficiency.

[0046] Combining Example One and Example Two, the working principle of the extended surface clamping indexing disk is as follows:

[0047] First, the staff selects an appropriate number of extension rods according to the size and shape of the workpiece to be processed. When the size of the workpiece exceeds the diameter of the fixed disk 1, the staff can expand the mounting end face of the fixed disk 1 by connecting the extension rods. The combination of the connecting rod 3 and the supporting rod 4 enables the mounting end face of the fixed disk 1 to be extended, thereby adapting to larger-sized workpieces. At the same time, six fixing rods 2 are provided on the fixed disk 1, which helps to evenly support the workpiece during the processing.

[0048] Secondly, after installing the extension rod, the staff can place the workpiece on the fixed disk 1 and fix the workpiece through the fixing holes 6 on the fixing rod 2, connecting rod 3 and supporting rod 4. The use of the supporting plate 5 further expands the contact area with the workpiece and improves the fixing effect. Through the cooperation of the bolt 7 and the nut 11, the supporting plate 5 can reciprocate horizontally along the through groove 10, so as to adjust to the optimal fixing position.

[0049] Finally, the rotating assembly enables the fixed disk 1 to rotate circumferentially, meeting the requirement of multi-angle machining of the workpiece. At the same time, the setting of the control panel makes the operation more convenient. The user can control the rotation state of the fixed disk 1 through the buttons and display screen on the panel to achieve precise machining.

[0050] In summary, through the setting of the extension rod and the addition of the rotating assembly, the surface-expanding clamping indexing disk realizes the fixation and multi-angle machining of larger-sized workpieces, improving the versatility and machining efficiency of the indexing disk.

[0051] In this specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.
