[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-6The utility model provides a technical solution: a laser processing machine tool accessory fixture for processing a turbine outer ring block, comprising a base plate 1, a connecting seat fixedly mounted on the lower wall of the base plate, two pairs of ear plates 2 fixedly mounted on the upper wall of the base plate 1, a blocking block 3 fixedly mounted on the base plate 1 and between each pair of the ear plates 2, a box body 4 fixedly mounted on the side wall of the ear plate 2, a screw rod 5 rotatably mounted in the box body 4, a moving block 6 slidably mounted in the box body 4, a first threaded hole opened on the moving block 6, and the moving block 6 is threaded through the first thread The hole is engaged and connected to the screw rod 5. A spring 7 is fixedly installed in the box body 4 and close to the side of the ear plate 2. A force block 8 is fixedly installed on the spring 7. A push rod 9 is fixedly installed on the force block 8. The push rod 9 passes through the box body 4 and the ear plate 2. A driving assembly is provided on the outer wall of the box body 4. The driving assembly is connected to the screw rod 5. A shaft rod 10 is rotatably installed between the blocking blocks 3. A bearing plate 11 is fixedly installed on the shaft rod 10. One end of the shaft rod 10 passes through the blocking block 3. A limit assembly is provided on the through end of the shaft rod 10.

[0023] Rotate the shaft 10 so that the shaft 10 drives the carrier plate 11 to rotate, thereby adjusting the inclination angle of the carrier plate 11, and limit the shaft 10 through the limit assembly to prevent the shaft 10 from rotating. At this time, place the outer ring block on the carrier plate 11, and rotate the drive assembly to rotate the screw rod 5. Since the screw rod 5 and the moving block 6 are engaged and connected through the first threaded hole, the screw rod 5 has a driving tendency to move the moving block 6. The moving block 6 moves toward the force block 8 in the box body 4. The moving block 6 pushes the force block 8, so that the force block 8 squeezes the spring 7 while pushing the push rod 9. The other end of the push rod 9 moves out until the push rod 9 contacts the outer ring block, and then the outer ring block is limited and fixed by increasing the pressure.

[0024] This embodiment is further configured such that a guide rail 12 is fixedly mounted on the inner wall surface of the box body 4 on the side away from the ear plate 2, the movable block 6 is slidably mounted in the guide rail 12, the force-bearing block 8 is a right-angled trapezoidal structure, and the movable block 6 is a right-angled trapezoidal structure;

[0025] The moving block 6 moves along the path of the guide rail 12 under the action of the guide rail 12. Since the force-bearing block 8 is a right-angled trapezoidal structure and the moving block 6 is a right-angled triangle structure, the hypotenuse of the right-angled trapezoidal structure of the force-bearing block 8 corresponds to the hypotenuse of the right-angled triangle structure of the moving block 6, so that when the moving block 6 moves, the force-bearing block 8 can be subjected to thrust.

[0026] This embodiment is further configured such that the drive assembly includes a protective box 13, the protective box 13 is fixedly mounted on the outer wall of the box body 4, one end of the screw rod 5 passes through the box body 4 and the protective box 13, a worm gear 14 is fixedly mounted on the through end of the screw rod 5, a worm 15 is rotatably mounted in the protective box 13, and the worm gear 14 is meshed with the worm 15;

[0027] The worm 15 is rotated. Since the worm 15 is meshed with the worm wheel 14, the worm 15 drives the worm wheel 14 to rotate, and the worm wheel 14 drives the screw 5 to rotate. The worm wheel 14 and the worm 15 have a self-locking function to prevent the screw 5 from rotating.

[0028] This embodiment is further configured such that the end of the worm 15 away from the ear plate 2 passes through the protective box 13, and a rotating disk 16 is fixedly mounted on the passing end of the worm 15;

[0029] The rotating disk 16 facilitates the worm 15 to rotate under force.

[0030] This embodiment is further configured as follows: the limit assembly includes a carrier box 17, the carrier box 17 is fixedly mounted on the blocking block 3, the through end of the shaft rod 10 passes through the carrier box 17, a gear 18 is fixedly mounted on the shaft rod 10, the gear 18 is located in the carrier box 17, a pair of through holes are opened on the lower wall of the carrier box 17, a limit rod 19 is inserted in the through holes, the upper end of the limit rod 19 is located in the box body 4, a limit rack 20 is fixedly mounted between the upper ends of the limit rods 19, a connecting plate 21 is fixedly mounted between the lower ends of the limit rods 19, a bolt 22 is rotatably mounted between the limit rack 20 and the connecting plate 21, a second threaded hole is opened on the lower wall of the carrier box 17 and is located between the pair of through holes, the bolt 22 is meshed and connected to the second threaded hole, and the lower end of the bolt 22 passes through the connecting plate 21;

[0031] Rotate the bolt 22 so that the bolt 22 is fed along the second threaded hole path, so that the bolt 22 pushes the limit rack 20. The limit rack 20 moves upward along the through hole path under the action of the limit rod 19 until the limit tooth engages with the gear 18, thereby preventing the gear 18 from rotating. At the same time, the shaft 10 is prevented from rotating.

[0032] This embodiment is further configured such that a disc 23 is fixedly mounted on the through end of the shaft 10, the disc 23 is provided with an angle scale, and a pointer 24 is fixedly mounted on the outer wall of the carrier box 17 and located above the disc 23;

[0033] The disc 23 facilitates the rotation of the shaft 10 , and the rotation angle of the shaft 10 can be observed through the pointer 24 and the angle scale.

[0034] This embodiment is further configured to have a gap between the ear plate 2 and the blocking block 3.

[0035] The gap between the blocking block 3 and the ear plate 2 facilitates processing of the workpiece at the gap.

[0036] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0037] Embodiment: According to the drawings in the specification, the base plate 1 is connected to the laser processing machine through a connecting seat, and the shaft 10 is rotated so that the shaft 10 drives the carrier plate 11 to rotate, thereby adjusting the inclination angle of the carrier plate 11, and the bolt 22 is rotated so that the bolt 22 is fed along the second threaded hole path, so that the bolt 22 pushes the limit rack 20, and the limit rack 20 moves upward along the through hole path under the action of the limit rod 19 until the limit tooth is engaged with the gear 18, thereby preventing the gear 18 from rotating. At the same time, the shaft 10 is prevented from rotating. At this time, the outer ring block is placed on the carrier plate 11, and the worm 15 is rotated. Since the worm 15 is engaged with the worm wheel 14, the worm 15 drives the worm wheel 14 when it rotates. The worm gear 14 rotates and drives the screw rod 5 to rotate. Since the screw rod 5 and the moving block 6 are meshed and connected through the first threaded hole, the screw rod 5 has a driving tendency to the moving block 6. The moving block 6 moves along the path of the guide rail 12 under the action of the guide rail 12. Since the force block 8 is a right-angled trapezoidal structure and the moving block 6 is a right-angled triangle structure, the hypotenuse of the right-angled trapezoidal structure of the force block 8 corresponds to the hypotenuse of the right-angled triangle structure of the moving block 6, so that when the moving block 6 moves, the force block 8 can be subjected to thrust, and the moving block 6 pushes the force block 8, so that the force block 8 squeezes the spring 7 while pushing the push rod 9. The other end of the push rod 9 moves out until the push rod 9 contacts the outer ring block, and then the outer ring block is limited and fixed by increasing the pressure.
