[0039] As shown in Figures 1-3 The rotating assembly 3 includes a fixed frame 301 and a rotating frame 302.

[0040] The fixed frame 301 is installed on the workbench 1, and the rotating frame 302 is connected with the cutting table 2. The rotating frame 302 is rotationally sleeved on the fixed frame 301. Since the rotating frame 302 is rotationally sleeved on the fixed frame 301, when the rotating frame 302 is not positioned by the locking mechanism 4, the rotating frame 302 can rotate around the fixed frame 301, so as to adjust the position of the cutting table 2, so that the grinding wheel 11 can cut along the cracks of the jade raw material 6.

[0041] As shown in Figures 1-3 The fixed frame 301 includes a first fixed plate 3011 installed on the workbench 1. The first fixed plate 3011 is provided with a connecting shaft 3012. The second fixed plate 3013 is connected to the end of the connecting shaft 3012 away from the first fixed plate 3011. The first fixed plate 3011, the second fixed plate 3013 and the connecting shaft 3012 jointly form an annular groove 3014 for rotationally limiting the rotating frame 302.

[0043] As shown in Figures 1-4 The locking mechanism 4 includes a hollow fixed seat 401 arranged on the workbench 1. The fixed seat 401 is provided with a pull rod 402 slidingly penetrating the fixed seat 401. The pull rod 402 is connected with a locking block 403 at the end facing the rotating assembly 3. The outer wall of the rotating frame 302 is provided with a locking disc 404. The locking block 403 corresponds to the locking disc 404 and is insertedly connected. The locking block 403 is inserted into the locking disc 404, so as to lock and fix the rotating assembly 3.

[0044] The end of the pull rod 402 away from the rotating assembly 3 is connected with an operation handle 405, a limiting block 406 is arranged on the pull rod 402 and located in the hollow cavity of the fixing seat 401, the limiting block 406 is fixedly connected with the pull rod 402 or is an integral structure, the limiting block 406 slides in the hollow cavity of the fixing seat 401, and the hollow cavity of the fixing seat 401 further compresses a spring 407, one end of the spring 407 abuts against the limiting block 406, and the other end abuts against the side wall of the hollow cavity of the fixing seat 401. The operation handle 405 can be operated to pull the pull rod 402 to move, thereby driving the locking block 403 to move away from the locking disc 404, so that the rotating frame 302 can rotate freely. In the moving process of the pull rod 402, the pull rod 402 drives the limiting block 406 to move synchronously, and the limiting block 406 compresses the spring 407 in the moving process. When the operation handle 405 is released, the pull rod 402 moves towards the locking disc 404 under the elastic force of the spring 407, thereby driving the locking block 403 to reinsert into the locking disc 404, and the rotating frame 302 is fixed.

[0045] As shown in Figure 4 , the end of the locking block 403 away from the pull rod 402 is provided with at least one tooth 4031, and the outer periphery of the locking disc 404 is arranged with a plurality of insertion grooves 4041 matched with the teeth 4031, the teeth 4031 are slidably arranged in the insertion grooves 4041. In the embodiment, two teeth 4031 are arranged, and a plurality of insertion grooves 4041 are arranged along the outer edge of the locking disc 404. The two teeth 4031 are inserted into the corresponding insertion grooves 4041, so that the locking disc 404 is fixed.

[0046] As shown in Figures 1-2 and Figure 5 , the adjusting and locking assembly 8 comprises two inclined pressing blocks 801 arranged on the threaded column 7, and the two inclined pressing blocks 801 are oppositely arranged on the top and bottom of the pressing plate 9. The side of the two inclined pressing blocks 801 away from the pressing plate 9 abuts against a locking bolt 802, and the locking bolt 802 is threadedly installed on the threaded column 7. The position of the pressing plate 9 in the vertical direction can be adjusted by loosening the locking bolt 802, so as to be applicable to jade raw materials 6 of different sizes, and the versatility of the device is increased. The two inclined pressing blocks 801 are arranged to enable the pressing plate 9 to be arranged obliquely. The low end of the obliquely arranged pressing plate 9 abuts against the jade raw material 6, the pressure on the jade raw material 6 is increased, and the fixation of the jade raw material 6 is more firm.

[0047] As shown in Figure 5 , the inclined surfaces of the two inclined pressing blocks 801 are parallel to and abut against the pressing plate 9. The inclined surfaces of the inclined pressing blocks 801 increase the contact area with the pressing plate 9, so that the locking bolt 802 fixes the pressing plate 9 more firmly.

[0048] As shown in Figures 1-2 and Figure 5As shown, a strip-shaped connecting groove 901 is provided at the through connection between the pressure plate 9 and the threaded column 7. The strip-shaped connecting groove 901 and the threaded column 7 are slidably engaged. When the locking bolt 802 is loosened, the position of the pressure plate 9 in the horizontal direction can be adjusted along the strip-shaped connecting groove 901, thereby making it suitable for jade raw materials 6 of different sizes and increasing the versatility of the device. In this embodiment, the width of the inclined pressure block 801 is greater than the width of the strip-shaped connecting groove 901.

[0049] like Figure 2 As shown, the cutting table 2 has a mounting groove 201 on the side away from the rotating component 3. The pad 5 and the threaded post 7 are both located in the mounting groove 201. The mounting groove 201 facilitates the installation and replacement of the pad 5.

[0050] For ease of understanding, the working process of this embodiment is described below:

[0051] like Figures 1-5 As shown, first, the jade raw material 6 is placed on the pad 5. The crack on the jade raw material 6 corresponds to the grinding wheel 11 of the cutting equipment 10. According to the size of the jade raw material 6, the locking bolt 802 is loosened, and the position of the pressure plate 9 along the height direction of the threaded column 7 and along the horizontal direction of the strip connecting groove 901 is adjusted so that the lower end of the pressure plate 9 is inclined and abuts against the jade raw material 6. Then, the locking bolt 802 is rotated, and the pressure plate 9 is locked by the inclined pressure block 801 so that the pressure plate 9 can press the jade raw material 6 tightly on the pad 5. Then, the cutting equipment 10 is started to cut the jade raw material 6 along the crack.

[0052] When the position of the jade raw material 6 needs to be adjusted, the lever 402 is moved by operating the handle 405. The lever 402 causes the locking block 403 to move away from the locking plate 404. At this time, the rotating frame 302 can be rotated freely to adjust the position of the jade raw material 6 so that the crack on the other side of the jade raw material 6 corresponds to the grinding wheel 11 of the cutting equipment 10. During the movement of the lever 402, the lever 402 will drive the limiting block 406 to move synchronously. During the movement of the limiting block 406, the spring 407 will be compressed. When the operating handle 405 is released, the lever 402 moves towards the locking plate 404 under the elastic force of the spring 407, thereby driving the locking block 403 to re-insert into the locking plate 404, realizing the re-fixation of the rotating frame 302, thus completing the adjustment of the position of the jade raw material 6.

[0053] In summary, this utility model provides a jade raw material cutting device that solves the problem that current cutting equipment requires multiple adjustments and clamping fixation when cutting along the cracks of jade raw materials, which is inconvenient to operate and time-consuming.

[0054] It should be understood that the use of these embodiments is by way of illustration only and is not intended to limit the scope of the present application. In addition, it should also be understood that, after reading the technical content of the present application, those skilled in the art can make various modifications, modifications and / or variations to the present application, and all of these equivalent forms also fall within the protection scope defined by the claims attached to the present application.
