[0002] At present, crystal is a quartz crystal mineral, its main chemical component is silicon dioxide, when pure, it forms colorless and transparent crystals, and after irradiation of trace elements, it forms different types of colors. Crystal is often used to make jewelry because of its unique beauty. In the crystal processing technology, the crystal needs to be polished to make its appearance smoother.

[0003] In the related technology, the crystal grinding and polishing machine heads currently on the market all use a cylinder to press down the grinding and polishing disc to grind and polish the workpiece. After completion, the cylinder returns to the origin, and the workpiece is replaced to continue grinding and polishing until the grinding and polishing disc is consumed to the thinnest working thickness.

[0004] With regard to the above-mentioned related technologies, during the continuous processing of the grinding disc, the thickness of the grinding and polishing disc will gradually wear and reduce, the telescopic stroke of the cylinder will gradually become longer, the gas consumption will continue to increase, and the time to extend and return to the origin of the cylinder will be longer. Therefore, there are problems of high energy consumption and low processing efficiency.

[0005] In view of this, it is indeed necessary to provide an intelligent, efficient and energy-saving crystal grinding and polishing machine head to solve the above-mentioned technical solutions. Utility Model Content

[0007] In order to achieve the above purpose, the utility model intelligent high-efficiency energy-saving crystal grinding and polishing machine head adopts the following technical solutions:

[0008] An intelligent, efficient and energy-saving crystal grinding and polishing machine head comprises a driving cylinder, a fixed frame, a head seat and a sliding frame, wherein the driving cylinder is fixedly connected to one end of the fixed frame, the head seat is fixedly connected to the other end of the fixed frame, a movement is slidably penetrated in the head seat, and a grinding and polishing disc is rotatably arranged at one end of the movement away from the driving cylinder; a sliding frame is slidably connected to the fixed frame, one end of the sliding frame is fixedly connected to the circumference of the movement, and the other end of the sliding frame is fixedly connected to a push rod, and the push rod is fixedly connected to the telescopic rod of the driving cylinder; a spline nut is sleeved on the circumference of the push rod, the inner wall of one end of the spline nut is threadedly connected to the circumference of the push rod, and the other end face of the spline nut abuts against the driving cylinder, and a driving assembly is also arranged on the fixed frame, and the driving assembly is used to drive the spline nut to rotate.

[0009] As an optimization of the intelligent, efficient and energy-saving crystal grinding and polishing machine head, the driving assembly includes a servo motor, a synchronous wheel and a synchronous belt. The servo motor is fixedly connected to the fixed frame. There are two synchronous wheels, one of which is sleeved on the circumference of the spline nut, and the other is sleeved on the circumference of the output shaft of the servo motor. The synchronous belt is sleeved on the circumference of the two synchronous wheels.

[0010] As an optimization of the intelligent, efficient and energy-saving crystal grinding and polishing machine head, a limiting frame is fixedly connected to the fixed frame, and the synchronous wheel is rotatably arranged on the limiting frame.

[0011] Compared with the prior art, the beneficial effect of the utility model is that: when the thickness of the grinding and polishing disc decreases, the extension and return amount of the driving cylinder driving the sliding frame through the push rod increase, and the spline nut is driven by the driving component to rotate relative to the push rod, so that the threaded engagement length of the spline nut and the push rod is reduced, and relative sliding occurs between the spline nut and the push rod, so that the spline nut is closer to the driving cylinder. When the driving cylinder returns, the spline nut abuts against the driving cylinder before the push rod, so that the push rod stays at a farther distance, reducing the return amount of the push rod, which can not only reduce the gas consumption of the driving cylinder and reduce the energy consumption of multiple continuous grinding and polishing, but also reduce the time of each return stroke, thereby improving processing efficiency.

[0020] The following is combined with Figure 1-3 , further details of this application are given.

[0021] This application provides an intelligent, high-efficiency and energy-saving crystal grinding and polishing machine head, which adopts the following technical solutions:

[0022] Reference Figure 1 and Figure 2 The intelligent high-efficiency and energy-saving crystal grinding and polishing machine head includes a driving cylinder 1, a fixed frame 2, a head seat 3 and a sliding frame 4. The fixed frame 2 includes a top plate 21, a guide column 22 and a bottom plate 23. There are four guide columns 22, which are installed between the top plate 21 and the bottom plate 23. The fixed frame 2 is a rectangular parallelepiped frame structure. The driving cylinder 1 is fixedly installed on the top surface of the top plate 21 by screws, and the telescopic rod 11 of the driving cylinder 1 passes through the top plate 21 toward the inside of the fixed frame 2. The head seat 3 is fixedly installed on the bottom surface of the bottom plate 23 by screws. A movement 31 is installed in the head seat 3. The movement 31 slides up and down relative to the head seat 3. A rotating shaft is rotatably installed in the movement 31. The end of the rotating shaft close to the driving cylinder 1 is connected to the driving wheel on the top surface of the bottom plate 23 through a coupling for coaxial rotation. The end of the rotating shaft away from the driving cylinder 1 is fixedly connected with a grinding and polishing disc 5 by screws. The grinding and polishing disc 5 can be a grinding disc or a polishing disc. The grinding and polishing disc 5 is used to grind or polish the workpiece.

[0023] Reference Figure 2 and Figure 3, a sliding frame 4 is slidably mounted on the fixed frame 2, and the sliding frame 4 is a rectangular frame structure, and the sliding frame 4 slides relative to the bottom plate 23. One end of the sliding frame 4 passes through the headstock 3 and is fixedly connected to the peripheral side of the movement 31, and a push rod 6 is welded to the other end of the sliding frame 4, and the end of the push rod 6 away from the sliding frame 4 is welded to the telescopic rod 11 of the driving cylinder 1. A spline nut 7 is sleeved on the peripheral side of the push rod 6, and the length of the spline nut 7 is longer than that of the push rod 6. The spline nut 7 is sleeved on the peripheral side of the push rod 6 and the telescopic rod 11 of the driving cylinder 1. The outer side of the push rod 6 is integrally formed with an external thread, one end of the spline nut 7 is threadedly connected to the push rod 6, and the other end of the spline nut 7 abuts against the cylinder body 12 of the driving cylinder 1. A driving assembly 8 is also installed on the fixed frame 2. The driving assembly 8 can drive the spline nut 7 to rotate relative to the push rod 6, change the screwing length of the spline nut 7 and the push rod 6, and drive the spline nut 7 to move a compensation distance in the direction close to the driving cylinder 1. The compensation distance is equal to the increment of the return amount relative to the initial value, so that the return amount of the driving cylinder 1 remains constant, thereby preventing the gas consumption of the driving cylinder 1 from increasing and reducing energy consumption; at the same time, it prevents the return time of the driving cylinder 1 from increasing and improves processing efficiency.

[0024] Specifically, the initial value of the return amount of the driving cylinder 1 when the grinding and polishing disc 5 is not worn is preset to be 15mm, the spline nut 7 is screwed on the push rod 6, and when the driving cylinder 1 moves 15mm in the return stroke, the spline nut 7 just abuts against the cylinder body 12 of the driving cylinder 1. When the wear thickness of the grinding and polishing disc 5 decreases by 1mm, the elongation of the driving cylinder 1 increases by 1mm, and the return amount of the driving cylinder 1 increases by 1mm relative to the initial value. The driving assembly 8 synchronously drives the spline nut 7 to rotate, so that the spline nut 7 moves 1mm in the direction close to the driving cylinder 1, so that when the spline nut 7 abuts against the driving cylinder 1, the return movement distance of the driving cylinder 1 is still 15mm, reducing the compressed air consumption and return time of the driving cylinder 11mm, thereby reducing energy consumption and improving processing efficiency.

[0025] In the preferred embodiment of the present application, refer to Figure 1 and Figure 2The driving assembly 8 includes a servo motor 81, a synchronous wheel 82 and a synchronous belt 83. The servo motor 81 is mounted on the side of the top plate 21 of the fixing frame 2 by screws, and the output shaft of the servo motor 81 faces the bottom plate 23. Two synchronous wheels 82 are installed, the inner ring of one synchronous wheel 82 matches the shape of the spline nut 7, the synchronous wheel 82 is sleeved on the circumference of the spline nut 7, and the other synchronous wheel 82 is tightly connected and sleeved on the circumference of the output shaft of the servo motor 81. The synchronous belt 83 is sleeved on the circumference of the two synchronous wheels 82 at the same time, and the angular displacement of the spline nut 7 is accurately controlled by the servo motor 81, so as to accurately adjust the compensation distance of the spline nut 7, which is conducive to maintaining the return amount of the driving cylinder 1 constant. Further, in production applications, the pulse signal of the servo motor 81 and the elongation of the driving cylinder 1 are associated and controlled through the MCU chip, and the pulse of the servo motor 81 can be feedback-controlled according to the change of the elongation of the driving cylinder 1, so as to realize intelligent control of the rotation direction and rotation angular displacement of the spline nut 7.

[0026] Further, refer to Figure 1 and Figure 2 A limit frame 9 is also welded on the fixed frame 2. The height of the limit frame 9 is aligned with the height of the output shaft of the servo motor 81. The limit frame 9 is a rectangular frame structure. One side of the synchronous wheel 82 is bonded to the limit frame 9. The synchronous wheel 82 is limited and fixed at the same height as the output shaft of the servo motor 81 and rotated on the limit frame 9, so that the synchronous belt 83 remains straight, thereby improving the transmission efficiency between the servo motor 81 and the synchronous wheel 82, thereby improving the adjustment accuracy of the servo motor 81, which is beneficial to improving the processing efficiency.

[0027] The experimental principle of the embodiment of the present application is as follows: when the thickness of the grinding and polishing disc 5 decreases during multiple grinding processes, the elongation of the driving cylinder 1 increases, and the return amount of the driving cylinder 1 increases synchronously. The servo motor 81 drives the spline nut 7 to rotate via the synchronous belt 83 and the synchronous wheel 82 according to the increment of the return amount of the driving cylinder 1, and adjusts the screwing length of the spline nut 7 and the push rod 6, so that the spline nut 7 moves in the direction close to the driving cylinder 1 and slides with the push rod 6. The distance of the spline nut 7 is equal to the increment of the return amount of the driving cylinder 1, so that when the spline nut 7 abuts against the cylinder, the return amount of the driving cylinder 1 remains unchanged, thereby reducing gas consumption and processing time, thereby reducing energy consumption and processing efficiency.

[0028] According to the disclosure and teaching of the above description, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the above specific implementation, and any obvious improvement, replacement or modification made by the technicians in this field on the basis of the utility model belongs to the protection scope of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the utility model.
