Description

Technical Field

[0001] This utility model relates to the field of crystal processing equipment technology, specifically to a crystal grinding auxiliary fixture based on magnetic positioning. Background Technology

[0002] In the field of modern precision manufacturing, crystals, as an important basic material, are widely used in many key industries such as optics and electronics. The quality of crystal grinding plays a decisive role in its subsequent performance, and the performance of the grinding fixture, as a key piece of equipment in the crystal grinding process, directly affects the accuracy, efficiency, and stability of crystal grinding.

[0003] Traditional crystal grinding fixtures have several shortcomings in practical applications. Regarding positioning accuracy, the mechanical positioning methods used in some fixtures are insufficient to meet the current requirements for high-precision crystal grinding. Even slight positioning deviations can lead to the crystal failing to meet expected dimensional accuracy and surface quality standards after grinding. In terms of clamping stability, some fixtures have poorly designed clamping structures, making it easy for the crystal to loosen or shift during grinding. This not only affects grinding accuracy but may also damage the crystal and the grinding equipment. Furthermore, existing fixtures have poor versatility; custom-made fixtures are often required for crystals of different shapes and sizes, increasing production costs and time. Utility Model Content

[0004] The purpose of this invention is to provide a crystal grinding auxiliary fixture based on magnetic positioning, so as to solve the problem of insufficient positioning accuracy in existing crystal grinding processes mentioned in the background art.

A height adjustment cylinder is embedded in the center of the top surface of the workbench, and a crystal tray for placing crystal workpieces is coaxially connected to the top of the lifting rod of the height adjustment cylinder. The piston rod end of the clamping adjustment cylinder is coaxially mounted with a rotating mechanism. The rotating mechanism includes a geared motor and a rotating shaft embedded inside the piston rod. The two sets of geared motors are synchronous working units. The end of the rotating shaft is coaxially connected to a replaceable clamping turntable, and a magnetic suction post is coaxially installed on the back of the replaceable clamping turntable.

[0019] Crystal grinding auxiliary fixtures based on magnetic positioning, such as Figures 1-3As shown, the system includes a workbench 10, with lifting hydraulic cylinders 20 installed at the center of each of the four sides of the workbench 10. Each set of lifting hydraulic cylinders 20 has a clamping adjustment cylinder 30 installed at its top. A height adjustment cylinder 11 is embedded in the center of the top surface of the workbench 10. The top of the lifting rod of the height adjustment cylinder 11 is coaxially connected to a crystal tray 12 for placing the crystal workpiece 60. A rotating mechanism 40 is coaxially installed at the end of the piston rod 31 of the clamping adjustment cylinder 30. The rotating mechanism 40 includes a reduction motor 41 embedded inside the piston rod 31 and a rotating shaft 42. Two sets of reduction motors 41 are synchronous working units, and two sets of lifting hydraulic cylinders 20 are synchronous working hydraulic cylinders. A replaceable clamping turntable 50 is coaxially connected to the end of the rotating shaft 42. A magnetic suction column 51 is coaxially installed on the back of the replaceable clamping turntable 50. The magnetic suction column 51 and the rotating shaft 42 are magnetically engaged. The workbench 10 serves as the base for the entire system. The fixture provides a stable support base; the lifting hydraulic cylinder 20 can adjust the height of the clamping adjustment cylinder 30 to accommodate crystal workpieces 60 of different sizes; the clamping adjustment cylinder 30 can adjust the clamping force on the crystal workpiece 60; the height adjustment cylinder 11 can adjust the height of the crystal tray 12 to ensure that the crystal workpiece 60 is at a suitable grinding height; the geared motor 41 in the rotating mechanism 40 drives the rotating shaft 42 to rotate, which in turn drives the replaceable clamping turntable 50 to rotate, and the synchronous operation of the two sets of geared motors 41 can ensure the stability of clamping and rotation; the magnetic column 51 is magnetically connected to the rotating shaft 42, which facilitates the replacement and positioning of the replaceable clamping turntable 50, so that this crystal grinding auxiliary fixture based on magnetic positioning can stably and efficiently clamp and position the crystal workpiece 60, which facilitates the grinding work, improves the grinding accuracy and efficiency, and has good versatility and replaceability.

[0020] Furthermore, a soft pad 13 is provided on the top surface of the crystal tray 12. The soft pad 13 is made of rubber and has a thickness of 2-4mm, which reduces scratches or damage caused by direct contact with the hard tray, while improving the uniformity and precision of grinding.

[0021] It is worth noting that the clamping adjustment cylinder 30 is vertically connected to the hydraulic cylinder 21 of the lifting hydraulic cylinder 20 to ensure the stability and accuracy of the clamping adjustment cylinder 30 during operation, so that the clamping force on the crystal workpiece 60 can be evenly distributed, avoiding clamping deviation or loosening caused by unstable connection.

[0022] Specifically, the surface of the replaceable clamping turntable 50 that contacts the crystal workpiece 60 is provided with an anti-slip pad 52, which significantly enhances the friction between the clamping turntable 50 and the crystal workpiece 60, effectively preventing processing errors or damage caused by workpiece slippage during the grinding process, and improving processing efficiency and safety.

[0023] In addition, the surface of the anti-slip pad 52 is equipped with several uniformly spaced anti-slip protrusions 53 to enhance the anti-slip effect, so that the crystal workpiece 60 can remain stable during the grinding process, and also helps to improve the uniformity and surface quality of the grinding.

[0024] The anti-slip pad 52 has a thickness of 3-6mm, and the anti-slip protrusion 53 has a height of 1-2mm. This ensures sufficient anti-slip performance while avoiding unnecessary interference to the grinding process caused by excessively thick or high pads and protrusions, thus ensuring the accuracy and efficiency of grinding.

[0025] The working principle of this magnetically positioned crystal grinding auxiliary fixture: First, place the crystal workpiece 60 on the crystal tray 12, start the height adjustment cylinder 11, and adjust the crystal tray 12 to a suitable height by lifting the lifting rod so that the crystal workpiece 60 is in the position required for grinding. The soft pad 13 on the top surface can protect the crystal workpiece 60. Next, the lifting hydraulic cylinder 20 operates to adjust the height of the clamping adjustment cylinder 30 according to the height of the crystal workpiece 60. Then, the piston rod 31 of the clamping adjustment cylinder 30 extends, so that the replaceable clamping turntable 50 is close to the crystal workpiece 60, the anti-slip pad 52 and its anti-slip protrusions 53 contact the crystal workpiece 60, and the clamping adjustment cylinder 30 applies a suitable clamping force to clamp the crystal workpiece 60. During the grinding process, if it is necessary to rotate the crystal workpiece 60, the geared motor 41 in the rotating mechanism 40 starts, driving the rotating shaft 42 to rotate, which in turn drives the replaceable clamping turntable 50 to rotate. The two sets of geared motors 41 work synchronously to ensure rotational stability. Since the magnetic column 51 and the rotating shaft 42 are magnetically connected, the replaceable clamping turntable 50 can be easily replaced according to the needs of different crystal workpieces 60. After grinding is completed, the clamping adjustment cylinder 30 is released, the piston rod 31 retracts, and the lifting hydraulic cylinder 20 descends, so that the crystal workpiece 60 can be taken out.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
