Description

Technical Field

[0001] The utility model relates to the field of ceramic processing, in particular to a zirconia ceramic block cutting mechanism. Background Art

[0002] Zirconia ceramics are white, and yellow or gray when containing impurities. They have the advantages of high toughness, high bending strength and high wear resistance, excellent thermal insulation performance, and a thermal expansion coefficient close to that of steel.

[0003] After the existing zirconia ceramics are manufactured, they are large in size, so they need to be cut into small pieces before they can be used to manufacture some small products, such as denture ceramic blocks. However, in the traditional rough machining and cutting process, the cutting machine has a complex structure and is equipped with corresponding tools, protective shells, controllers, motors and other components. It is heavy. After completing a cut, the cutting machine needs to be manually lifted to ensure that the tool is separated from the ceramic block. When performing multiple cutting operations, the actual labor intensity of the staff is high, which leads to the problem of low cutting efficiency. Utility Model Content

[0004] The utility model aims to provide a zirconia ceramic block cutting mechanism to solve the problems raised in the background technology in view of the deficiencies of the prior art.

[0010] Preferably, the bolt passes through the screw holes of the first base and the support frame, the end of the bolt extends to the inside of the first base, and an abutment block is installed at the end of the bolt.

[0011] The beneficial effects of the utility model are:

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-5As shown, a zirconia ceramic block cutting mechanism includes a base frame 1, baffle rods 14 are installed on both sides of the base frame 1, and the baffle rods 14 extend vertically upward to form two parallel rod structures, and a mounting rod 2 is movably installed between the two baffle rods 14 through a bearing, and the entire mounting rod 2 can rotate when subjected to force, and in the subsequent cutting process, the mounting rod 2 is used with the help of the lever principle, and a cutter 4 is fixedly sleeved on the surface of the mounting rod 2, and a motor 3 is fixedly connected to the top of the cutter 4, and the motor 3 is a driving component and has its own weight, and the cutter 4 mainly includes existing components such as a protective shell, a cutter, and a rotating shaft, and the motor 3 drives the cutter 4 to work, and the bottom of the motor 3 A traction rod 7 is installed at the bottom, and the traction rod 7 is arranged to extend obliquely downward. A guide rail 8 is fixedly connected to the left and right sides of the upper surface of the base frame 1, which is used as a motion limiting component. A mounting device 10 is installed above the two guide rails 8. The mounting device 10 is used to place the large porcelain block to be cut, and two groups of bases are installed at the bottom of the mounting device 10 directly above the two guide rails 8. The base consists of a first base 9 and a second base 15, and the first base 9 is limitedly matched with the guide rail 8 below. It should be noted that because the guide rail 8 has a certain height, the length of the first base 9 needs to be greater than the second base 15, thereby ensuring that the first base 9 and the guide rail 8 can be limitedly matched left and right.

[0021] Specifically, a cutting groove corresponding to the cutter 4 is formed on the surface of the mounting device 10 , and the cutting groove is used with the cutting tool to cut the workpiece.

[0022] Furthermore, the end of the traction rod 7 is hinged with a bottom rod 5, and the two can rotate relative to each other, while forming the effect of supporting and transmitting power, and two spring uprights 6 are evenly distributed on the surface of the bottom rod 5, and the top ends of the two spring uprights 6 are installed under the top of the base frame 1, which can realize the spring reaction force, which is conducive to the rebound of the bottom rod 5, and then drive the traction rod 7 upward, prompting the motor 3 to make an upward rotational movement around the mounting rod 2, driving the cutting tool to press down, and assisting in completing the cutting movement.

[0023] Furthermore, rollers 12 are installed on the inner sides of the first base 9 and the second base 15 via the rotating shaft. The rollers 12 have wheel grooves, which can contact and limit the guide rail 8, thereby reducing the friction of movement, and facilitating a more stable movement of the mounting device 10 thereon. Because of the first base 9 and the second base 15, the rollers 12 of the two are respectively located at the upper and lower positions of the guide rail 8, which can constitute an upper and lower limit effect, and further increase the structural stability.

[0024] Furthermore, a support frame 11 is sleeved on the lower surface of the first base 9, and the support frame 11 is sleeved on the lower part of the first base 9 in a U-shaped state, and the surface of the support frame 11 and the surface of the first base 9 are aligned with screw holes, and the screw holes pass through the first base 9 and the support frame 11.

[0025] Furthermore, the bolt 13 passes through the screw holes of the first base 9 and the support frame 11, and the end of the bolt 13 extends to the inside of the first base 9. A resistance block is installed at the end of the bolt 13. When the bolt 13 is driven to rotate, the resistance block can be caused to contact and tighten with the roller 12 inside the first base 9 to prevent the roller 12 from rotating, thereby achieving the effect of fixing the mounting device 10.

[0026] The method of using this embodiment is: when using, please refer to Figure 1-5 First, the staff is required to manually place the zirconia ceramic workpiece on the surface of the fixture 10, and align the predetermined cutting line on the surface of the zirconia ceramic workpiece with the cutting groove on the surface of the fixture 10, so that the cutter 4 can cut the zirconia ceramic workpiece. During the process of cutting the zirconia ceramic workpiece, the staff manually presses the cutter 4 down to complete the cutting of the ceramic block. At this time, the pressure on the cutter 4 is removed, and under the action of the motor 3's own gravity, the motor 3 rotates around the mounting rod 2 and moves downward, the cutter 4 moves upward and separates from the ceramic block, the traction rod 7 moves downward, the bottom rod 5 moves downward with one side, and the other side is connected to the spring upright rod 6. At this time, the spring upright rod 6 is connected to the bottom end of the bottom frame 1. When the cutter 4 is in contact with the spring, the spring is squeezed and begins to accumulate. When the next cutting is performed, when the cutter 4 is manually pressed downward, the spring of the spring upright 6 stretches and generates a reaction force. The reaction force, together with the pressure applied manually, overcomes the gravity of the motor 3, and again causes the cutting tool to contact the ceramic block below to complete the second cutting. During the whole process, the force used manually is relatively small. When the position of the mounting device 10 needs to be fixed according to different current needs, the staff manually screws the bolt 13 on the surface of the first base 9, and the end of the bolt 13 contacts the surface of the corresponding roller 12, so that the mounting device 10 is fixed at a fixed position on the surface of the guide rail 8 by means of friction resistance.

[0027] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
