[0002] Due to its stable and precise frequency control characteristics, quartz crystals are widely used in the communication and electronics industries, including satellite communication, mobile communication, optical fiber communication, as well as fields such as computers, consumer electronics, and measuring instruments. The high precision and stability of quartz crystal components provide an important guarantee for the normal operation of electronic devices. With the rapid development of communication and electronic technologies, the market demand for quartz crystals has increased significantly, and at the same time, the performance requirements for quartz crystals are also constantly improving. Therefore, quartz crystal processing technologies also need to be continuously innovated and developed. The processing of quartz crystals includes multiple steps such as cutting, grinding, and polishing. Especially for quartz crystals after AT cutting, their long sides are inclined, and bevel grinding is required to ensure the performance and consistency of the crystals. Before bevel grinding, a series of sorting and alignment operations need to be carried out on the crystals, and then bevel grinding is performed. The purpose is to fully grind the bevel edges of each crystal. The existing quartz crystal grinding uses manual operations for sorting and alignment, resulting in problems such as inaccurate alignment, insufficient grinding, and low production efficiency. These problems may affect the performance and consistency of the crystals, and further affect the stability of the entire communication or electronic system. Therefore, a jig for fixing the crystal is designed to meet the current usage requirements. Content of the Utility Model

The module and pressure angle of the planetary gear 6 are the same as those of the outer ring gear and the central gear of the grinding machine. A crystal placement groove 61 is arranged in the middle of the planetary gear 6. Locking spacers 7 are relatively arranged on the inner sides of the two side walls at both ends of the crystal placement groove 61. The space between the locking spacers 7 is used to clamp the crystal 9. The width of the crystal placement groove 61 is the same as the size of the crystal 9 to be ground. Locking screws 8 are arranged on the relative outer sides of the locking spacers 7. The locking screws 8 are screwed into the planetary gear 6. When the locking screws 8 are tightened, the two locking spacers 7 approach each other and clamp all the crystals 9 in the crystal placement groove 61; a switching spacer 5, which is detachably arranged on the upper side of the fixture body 1 below the crystal placement groove 61, is used to adapt to quartz crystals of different sizes. Through a mechanized fixing and alignment method, the manual operation error is reduced, and the position of each quartz crystal during the grinding process is ensured to be accurate, thereby improving the grinding accuracy and product consistency.
[0021] In this embodiment, as Figure 2 shown, a stop block 10 is arranged on one side of the fixture body 1, which has a simple structure and is convenient to install.
[0022] In this embodiment, as Figure 2 shown, a square glass groove 4 is arranged on the side of the fixture body 1 close to the stop block 10, which can accommodate spare glass, enabling the spare glass to be properly stored, providing great convenience for the subsequent installation process of the crystal 9, and thus improving the overall operation efficiency.
[0023] In this embodiment, as Figure 4As shown, a circular groove 3 matching the planetary gear 6 is provided in the middle of the upper side of the fixture body 1. A square groove 2 matching the switching spacer 5 is provided below the circular groove 3.
