[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] Please refer to Figures 1 to 4 The utility model discloses a single crystal ingot cutting fixture, which comprises: a mobile platform 100, which can perform reciprocating linear motion, a clamping space 110 for clamping the single crystal ingot is provided on the mobile platform 100, and a groove 120 for the diamond rope of the cutting machine to pass through is provided on the mobile platform 100; a clamping plate 200, which is detachably fixedly connected to the mobile platform 100, and the clamping plate 200 is located on one side of the clamping space 110; at least one clamping mechanism 300, which comprises a fixing seat 310, The screw 320 and the clamping block 330, the fixed seat 310 is detachably fixedly connected to the mobile platform 100, the screw 320 passes through the fixed seat 310 and is screwed to the fixed seat 310, the clamping block is detachably fixedly connected to one end of the screw 320 close to the clamping plate 200, and the clamping block is located on the other side of the clamping space 110; and a plurality of pads 400, which are placed on the mobile platform 100, and the plurality of pads 400 are arranged at intervals at the bottom of the clamping space 110, and the groove 120 is located between two pads 400.

[0020] In the embodiment of the utility model, the single crystal ingot is placed in the clamping space 110, and the screw 320 is rotated so that the clamping block 330 approaches and presses against the single crystal ingot, and the single crystal ingot is clamped under the joint action of the clamping plate 200 and the clamping block 330. The screw 320 is screwed with the fixing seat 310, and the clamping block 330 is fixedly connected with the screw 320. When the screw 320 is rotated, the clamping block 330 can be driven to approach or move away from the clamping plate 200. When the clamping block 330 approaches the clamping plate 200, it can cooperate with the clamping plate 200 to clamp the single crystal ingot and cut the single crystal ingot; when the clamping block 330 is away from the clamping plate 200, the clamping block 330 and the clamping plate 200 will loosen the single crystal ingot, and the single crystal ingot can be taken out of the clamping space 110 or moved.

[0021] The mobile platform 100 is provided with a groove 120 for the diamond rope of the cutter to pass through. When the single crystal ingot is cut, the single crystal ingot is partially located above the groove 120, and the diamond rope of the cutter will continue to penetrate into the groove 120 to cut the single crystal ingot. By providing the groove 120, the mobile platform 100 is prevented from interfering with the movement of the diamond rope of the cutter.

[0022] The clamping plate 200 is detachably fixedly connected to the mobile platform 100, and can be, but not limited to, detachably fixedly connected to the mobile platform 100 by a plurality of bolts. The clamping plate 200 is perpendicular to the mobile platform 100, so as to better cooperate with the clamping block 330 to clamp the single crystal ingot.

[0023] A plurality of pads 400 are placed on the mobile platform 100 , and the single crystal ingot is placed on the plurality of pads 400 . The plurality of pads 400 can prevent the single crystal ingot from contacting the mobile platform 100 , thereby avoiding damage to the single crystal ingot.

[0024] The groove 120 is located between two cushion blocks 400 . The position of the groove 120 is also the truncation position. The cushion blocks 400 can support both sides of the truncation position of the single crystal ingot, thereby ensuring the force balance of the single crystal ingot during the truncation process.

[0025] Furthermore, it also includes a positioning block 130 which is fixedly connected to the mobile platform 100 . The positioning block 130 is located at one end of the clamping space 110 .

[0026] In the embodiment of the utility model, by providing a positioning block 130 on the mobile platform 100, when the single crystal ingot is placed in the clamping space 110, the positioning block 130 can position the single crystal ingot, so as to facilitate cutting of the single crystal ingot.

[0027] Furthermore, the clamping block 330 is made of rubber material. When the clamping block 330 is pressed against the single crystal ingot, the clamping block 330 is prevented from damaging the single crystal ingot.

[0028] Further, the cushion block 400 is a wooden cushion block 400. When the cushion block 400 supports the single crystal ingot, the wooden cushion block 400 can avoid damaging the single crystal ingot.

[0029] Furthermore, the cushion block 400 is provided with an arc-shaped opening 410 with an angle of 120°.

[0030] In an embodiment of the utility model, when the pad 400 supports the single crystal ingot, the single crystal ingot is located in the arc-shaped opening 410. Since the single crystal ingot is a cylinder, the arc-shaped opening 410 can better fit the side wall of the single crystal ingot, thereby preventing the single crystal ingot from rolling relative to the pad 400.

[0031] Further, the radius of the arc-shaped opening 410 is any one of 102 mm, 127 mm, 153 mm and 204 mm.

[0032] In an embodiment of the utility model, the cushion block 400 is provided with four specifications of arc-shaped openings 410, and one specification of arc-shaped opening 410 corresponds to one size of crystal rod. When cutting off a 4-inch crystal rod, a cushion block 400 with an arc-shaped opening 410 radius of 102 mm is used to support the crystal rod. When cutting off a 5-inch crystal rod, a cushion block 400 with an arc-shaped opening 410 radius of 127 mm is used to support the crystal rod. When cutting off a 6-inch crystal rod, a cushion block 400 with an arc-shaped opening 410 radius of 153 mm is used to support the crystal rod. When cutting off an 8-inch crystal rod, a cushion block 400 with an arc-shaped opening 410 radius of 204 mm is used to support the crystal rod. By setting cushion blocks 400 of various specifications, the processing requirements for crystal rods of different sizes can be met.

[0033] Furthermore, one end of the screw rod 320 away from the clamping block 330 is fixedly connected to a hand wheel 321 .

[0034] In the embodiment of the utility model, by providing a hand wheel 321, it is convenient to rotate the screw rod 320, so as to clamp or loosen the single crystal ingot, which is convenient for operation.

[0035] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical solution.
