[0007] By the above technical scheme, the side wall surfaces in contact with the crystal holder in the movable guide rail and the fixed guide rail are respectively arranged in an inclined shape, after the material is fixed at the bottom of the crystal holder, the movable guide rail is driven by the linear driving assembly to move towards the direction of the crystal holder, at this time, the locking force of the movable guide rail and the fixed guide rail acting on the crystal holder is arranged in an inclined shape, at this time, the locking force can be decomposed into a horizontal component and a vertical component, the horizontal component can push the crystal holder towards the direction of the fixed guide rail, and then the crystal holder is pressed on the first inclined surface of the fixed guide rail, the vertical component can push the crystal holder to move in the upward direction, and then the crystal holder is pressed on the vertical surface of the fixed guide rail, at this time, the crystal holder is clamped and subjected to forces in the vertical and horizontal directions, at this time, the required locking force requirement can be reduced, thereby reducing the production difficulty and cost; and when the same locking force is applied to the crystal holder, the locking force in the device can achieve more stable locking effect.

[0008] In addition, when the movable guide rail extrudes the crystal holder to move, the contact surfaces of the crystal holder and the movable guide rail and the fixed guide rail ensure the contact rate in a scraping manner, which can improve the cutting accuracy and ensure the stability of cutting.

[0009] Further, the support is arranged in an "L" shape, the bottom of the movable guide rail is arranged at the top of the horizontal part of the support, and the side vertical surface of the movable guide rail abuts against the side vertical surface of the vertical part of the support.

[0012] By the above technical scheme, by arranging at least two locking cylinders, the output shaft of the locking cylinder can apply force to the movable guide rail from different positions of the movable guide rail, thereby ensuring that different positions of the crystal holder are uniformly distributed on the full length of the movable guide rail, thereby reducing local stress concentration and improving the stability of the movable guide rail during movement;

[0013] In addition, the plurality of locking cylinders can ensure that the movable guide rail always maintains linear movement during movement, avoids deflection or bending caused by insufficient or uneven thrust of a single locking cylinder, and the synchronous operation of the plurality of locking cylinders can effectively offset the vibration generated when a single locking cylinder is working, thereby improving the stability of the system and the machining precision of the product.

[0014] Further, one end face of the support, the fixed guide rail and the guide plate in the length direction is flush, and the fixed guide rail is provided with a baffle plate at one end corresponding to the guide plate in a flush state, the baffle plate is arranged along the width direction of the clamp body, and the guide plate and the support are abutted on the side vertical surface of the baffle plate.

[0015] Through the above technical scheme, by arranging the baffle plate, the one end of the crystal holder is abutted on the side wall of the baffle plate during installation, which can ensure that the installation position of the crystal holder is the same each time, reduce the cutting error caused by position deviation, and improve the cutting precision of the product.

[0016] In addition, the baffle plate can limit the movement of the crystal holder in the length direction during clamping of the crystal holder by the movable guide rail and the fixed guide rail, thereby reducing the probability of slight displacement of the crystal holder under the influence of the cutting force, thereby improving the stability of clamping; and one end of the crystal holder is limited and fixed by the baffle plate, and the other end of the crystal holder is clamped by the movable guide rail and the fixed guide rail, so that the stability of the crystal holder can be better maintained after the two ends of the crystal holder are constrained, thereby reducing deformation during cutting, and improving cutting effect.

[0020] Through the above technical scheme, the stability between the connecting plate and the locking cylinder is improved by increasing the contact area with the connecting plate through the arrangement of the connecting plate and the flange cover.

[0021] The above scheme has the following advantages:

[0022] 1. By arranging the side wall surfaces of the movable guide rail and the fixed guide rail in contact with the crystal holder to be inclined, after the material is fixed at the bottom of the crystal holder, the movable guide rail is driven to move towards the direction of the crystal holder by the linear driving assembly. At this time, the locking force of the movable guide rail and the fixed guide rail acting on the crystal holder is arranged to be inclined. The locking force can be decomposed into a horizontal component and a vertical component. The horizontal component can push the crystal holder towards the fixed guide rail, so that the crystal holder is pressed on the first inclined surface of the fixed guide rail. The vertical component can push the crystal holder to move upwards, so that it is pressed on the vertical surface of the fixed guide rail. At this time, the crystal holder is clamped and subjected to forces in the vertical and horizontal directions. At this time, the required locking force can be reduced, thereby reducing the production difficulty and cost. In addition, when the crystal holder is pressed and moved by the movable guide rail, the contact surface of the crystal holder and the movable guide rail and the fixed guide rail is scraped to ensure the contact rate, which can improve the cutting accuracy and ensure the stability of the cutting;

[0023] 2. By arranging the "L" shaped support, when the crystal holder does not need to be clamped, the movable guide rail is at the right angle in the support at this time. The support provides support force to the movable guide rail, thereby improving the stability of the movable guide rail.

[0024] 3. By arranging at least two locking cylinders, the output shaft of the locking cylinder can apply force to the movable guide rail from different positions of the movable guide rail, thereby ensuring that the different positions of the crystal holder are uniformly distributed on the full length of the movable guide rail, thereby reducing local stress concentration and improving the stability of the movable guide rail during movement. In addition, multiple locking cylinders can ensure that the movable guide rail always moves in a straight line during movement, avoiding deflection or bending caused by insufficient or uneven pushing force of a single locking cylinder. The synchronous work of multiple locking cylinders can effectively offset the vibration generated when a single locking cylinder works, thereby improving the stability of the system and the processing precision of the product.

[0025] 4、Through the setting of the baffle, when the crystal holder is installed, one end of the crystal holder abuts against the side wall surface of the baffle, which can ensure that the installation position of the crystal holder is the same each time, reduce the cutting error caused by the position deviation, and further improve the cutting precision of the product; in addition, the baffle can limit the movement of the crystal holder in the length direction during the clamping of the crystal holder by the movable guide rail and the fixed guide rail, thereby reducing the probability of the crystal holder being slightly displaced under the influence of the cutting force, and improving the stability of the clamping; and one end of the crystal holder is limited and fixed by the baffle, and the other end of the crystal holder is clamped by the movable guide rail and the fixed guide rail, so that the stability of the crystal holder can be better maintained after the two ends of the crystal holder are respectively constrained, thereby reducing the deformation in the cutting process, and improving the cutting effect;

[0026] 5、Through the fact that the guide plate is slightly smaller than the accommodating groove in the crystal holder, in the process that the movable guide rail drives the crystal holder to move towards the fixed guide rail, after the preliminary positioning of the crystal holder is realized, the crystal holder is still left with movable space, so that the accurate clamping and positioning of the crystal holder are ensured; and the guide plate and the accommodating groove are both arranged in an inverted "T" shape, so that the contact area of the guide plate and the crystal holder can be improved, thereby improving the stability of the crystal holder after installation, and the crystal holder can be quickly disassembled and assembled, thereby reducing the production difficulty and cost;

[0027] 6、Through the setting of the connecting plate and the flange cover, the stability between the connecting plate and the locking cylinder is improved by increasing the contact area with the connecting plate. BRIEF DESCRIPTION OF DRAWINGS
