Description

Technical Field

[0001] The utility model relates to the technical field of jade processing, in particular to a jade blank cutting device. Background Art

[0002] Jade is a kind of mineral. There are two types of jade, soft and hard. Usually, the jade mentioned refers to soft jade, which belongs to one of the most common jewels. A jade blank refers to the raw jade material that has not been carved or polished, and it is the basic material for carving jade products. Generally, the directly mined jade blanks need to go through multiple processes to obtain wearable jade. Whether it is large or small jade, the first step is cutting, which requires processes such as blanking and profiling. First, the irregular or large jade is cut into the required size and then carved and polished. After being processed, the jade blanks can be made into various shaped utensils or jewelry, such as jade pendants, jade bottles, jade bi disks, etc.

[0003] At present, most of the equipment used for cutting jade has a complex structure and cannot effectively clamp and fix the jade to be cut. If the clamping force is too large, the jade will be damaged. If the clamping force is too small, the clamping firmness of the jade is poor, and the jade may shake during the cutting process, thus unable to achieve precise cutting of the jade, and the cutting quality is difficult to meet the requirements. In addition, the current cutting equipment is difficult to flexibly adjust the cutting angle. After clamping and fixing the jade, it is difficult to cut the jade according to the required cutting angle, making the cutting of the jade cumbersome and inconvenient. Summary of the Utility Model

[0038] In one embodiment, as Figures 1 to 3As shown together, the base 3 is hingedly installed on the workbench 101. The workbench 101 is provided with an arc-shaped slot 1012 centered on the hinge point of the base 3. A positioning bolt 4 is installed on the base 3. The positioning bolt 4 passes through the arc-shaped slot 1012 and is threadedly installed with a positioning block 5. When in use, loosen the positioning bolt 4, and the swing adjustment of the base 3 around the hinge point can be realized. Furthermore, the flexible adjustment of the cutting angle of the cutting grinding wheel 16 can be realized according to requirements. After the adjustment is completed, just tighten the positioning bolt 4 again.

[0040] As Figures 1 to 3 shown together, to realize the hinged installation of the mounting plate 7 on the base 3, in this embodiment, a fixed shaft 8 is fixedly installed at the top of the base 3. Both ends of the fixed shaft 8 are provided with first bearing seats 9. The first bearing seats 9 are fixedly connected with the mounting plate 7. The mounting plate 7 is hingedly installed on the base 3 through the fixed shaft 8 and the first bearing seats 9.

[0041] As Figures 1 to 3 shown together, the first driving device includes a cutting motor 10. The cutting motor 10 is fixedly installed on the mounting plate 7. A driving pulley 11 is installed on the output shaft of the cutting motor 10. A rotating shaft 13 is rotatably installed on the mounting plate 7 by using a second bearing seat 12. The cutting grinding wheel 16 is installed at one end of the rotating shaft 13. A driven pulley 14 is installed at the other end of the rotating shaft 13. A transmission belt 15 is wound between the driving pulley 11 and the driven pulley 14. The driving pulley 11 is in transmission connection with the driven pulley 14 through the transmission belt 15. When the cutting motor 10 works, it drives the driving pulley 11 to rotate, drives the driven pulley 14 to rotate through the transmission belt 15, and further drives the cutting grinding wheel 16 to rotate.

[0042] In one embodiment, as Figures 1 to 3 shown together, a first protective cover 17 covering the driving pulley 11, the driven pulley 14 and the transmission belt 15 is fixedly installed on the mounting plate 7. The first protective cover 17 realizes the dust protection of the driving pulley 11, the driven pulley 14 and the transmission belt 15, and improves the use safety factor of the device; a second protective cover 18 covering the top of the cutting grinding wheel 16 is also fixedly installed on the mounting plate 7. The second protective cover 18 can prevent the jade powder cut from scattering and splashing, and improves the use safety factor.

[0043] In one embodiment, as Figures 1 to 3As shown together, one end of the pressure bar 19 away from the mounting plate 7 is provided with a handle 20, which is convenient for workers to hold, can increase the holding friction, and is easy to use.

[0044] As Figures 4 to 6 As shown together, the second driving device includes a servo motor 24 fixedly installed on the clamping seat 21. A gear 25 is installed on the output shaft of the servo motor 24. A toothed bar 2302 meshing with the gear 25 is provided on one side of the sliding seat 23 close to the gear 25. When the servo motor 24 works, it drives the gear 25 to rotate, and then drives the two sliding seats 23 to slide axially along the first guide rod 22 towards or away from each other.

[0045] As Figures 5 to 7 As shown together, in this embodiment, there are two groups of first guide rods 22, which are respectively arranged on both sides close to the clamping seat 21. Each group of first guide rods 22 has two and is arranged in parallel to ensure that the sliding seat 23 and the slider 28 slide smoothly along the first guide rod 22.

[0046] As Figures 5 to 8 As shown together, in one embodiment, a detection part 2303 is provided at the bottom of the sliding seat 23. A detection switch 26 corresponding to the detection part 2303 is fixedly installed on the clamping seat 21. The detection switch 26 is used to detect the detection part 2303. When the detection switch 26 detects the detection part 2303, the detection switch 26 feeds the detection signal back to the control system, and the control system controls the servo motor 24 to stop working. At this time, the sliding seat 23 is located at the end of the sliding stroke.

[0047] As Figure 8 As shown, in this embodiment, the spring resisting part 2301, the detection part 2303 and the toothed bar 2302 are all integrally formed structures of the sliding seat 23.

[0048] As Figures 4 to 7 As shown together, in one embodiment, a second guide rod 30 parallel to the first guide rod 22 is also fixedly installed on the clamping seat 21. One end of the slider 28 close to the jaw 29 is slidably sleeved on the second guide rod 30, and one end of the slider 28 away from the jaw 29 is slidably sleeved on the first guide rod 22. The provided second guide rod 30 can avoid clamping shaking and make the clamping of the jade more stable.

[0049] In one embodiment, as Figures 4 to 7 As shown together, clamping teeth 2901 are provided on the opposite sides of the jaw 29, which makes the clamping of the jade more firm.

[0050] The jade blank cutting device based on the above structure is simple in structure. When in use, place the jade blank to be cut between the two clamping jaws 29, and then the second driving device works to drive the two sliding seats 23 to move towards each other. Furthermore, the slider 28 is pushed to move through the compression spring 27, driving the two clamping jaws 29 to move towards each other to realize the clamping and fixing of the jade. After that, control the first driving device to work to drive the cutting grinding wheel 16 to rotate and press down the pressure bar 19, and then the cutting grinding wheel 16 can be driven to move downward to realize the cutting of the jade.

[0051] Through this jade blank cutting device, effective clamping and fixing of the jade can be realized. While the clamping of the jade is firm and reliable, it will not cause clamping damage to the jade, and the clamping operation is simple and convenient. Furthermore, high-precision cutting of the jade can be realized, and the cutting is efficient and fast, which is convenient and practical.
