[0029] Two shells 6, both of which are slidably connected to the bottom inner wall of the slide slot 12, and the same rotating rod 20 is rotatably penetrated inside the shells 6;

[0030] A clamping assembly, which is disposed at one end of the rotating rod 20 and is used to clamp the casting;

[0031] A driving assembly, which is disposed inside the slide slot 12 and is used to adjust the position of the housing 6;

[0032] The brake assembly is arranged on the bottom inner wall of the groove 10 and is used to brake the position of the rotating rod 20.

[0033] In the utility model, the clamping assembly includes a mounting tube 4 fixedly connected to one end of a rotating rod 20, the outer wall of the mounting tube 4 is provided with a plurality of threaded grooves 22, the internal threads of the threaded grooves 22 are connected to a threaded rod 21, and one end of the threaded rod 21 is fixedly connected to a clamping member 5. When the clamping member 5 needs to be replaced, the servo motor 14 can be started again to make the two sliders 15 move away from each other. At this time, the second circular hole 18 is disengaged from the insertion rod 8. When the two outer shells 6 are away from each other, due to the setting of the overrunning clutch 17, the two rotating rods 20 will not rotate. When the two outer shells 6 are close to each other again, the rack 13 drives the gear 19 to rotate, the gear 19 drives the rotating rod 20 to rotate, the rotating rod 20 drives the mounting tube 4 to rotate, and the mounting tube 4 drives the clamping member 5 to rotate. Since the shapes and sizes of the plurality of clamping members 5 are different, the clamping member 5 can be adjusted to a position suitable for the casting, thereby improving the scope of application of the device.

[0034] In particular, the driving assembly includes a same bidirectional screw rod 11 rotatably connected between the inner walls on both sides of the slide groove 12, a servo motor 14 is fixedly connected to one side of the base plate 1, the output shaft of the servo motor 14 rotates through the base plate 1 and is fixedly connected to one end of the bidirectional screw rod 11, and two symmetrically arranged sliders 15 are slidably connected to the bottom inner wall of the slide groove 12, the bidirectional screw rod 11 is threaded through the two sliders 15, and the top of the slider 15 is fixedly connected to the bottom of the shell 6. When the casting needs to be clamped, the casting can be placed on the operating groove 3 according to the indication of the indicator arrow 2, and the servo motor 14 is started. The output shaft of the servo motor 14 drives the bidirectional screw rod 11 to rotate, and the bidirectional screw rod 11 drives the two sliders 15 to approach each other, and the two sliders 15 drive the two shells 6 to approach each other.

[0035] In particular, the brake assembly includes a fixed block 9 fixedly connected to the middle position of the inner wall at the bottom of the groove 10, and the two sides of the fixed block 9 are fixedly connected with the insertion rod 8. A plurality of second circular holes 18 are opened inside the rotating rod 20, and two symmetrically arranged first circular holes 7 are opened inside the outer shell 6. The first circular hole 7 and the second circular hole 18 are used in conjunction with the insertion rod 8. At this time, the insertion rod 8 is always inside the second circular hole 18, and the rotating rod 20 cannot rotate. The outer shell 6 drives the two mounting cylinders 4 to approach each other, and the two mounting cylinders 4 drive the corresponding two clamping parts 5 to approach each other, clamping the casting for convenience of subsequent processing.

[0036] In particular, an indicating arrow 2 is provided at the middle position of the bottom inner wall of the operation slot 3 .

[0037] In particular, the sizes and shapes of the plurality of clamping members 5 are different.

[0038] In particular, an overrunning clutch 17 is provided on the outer wall of the rotating rod 20, and a gear 19 is provided on the outer wall of the overrunning clutch 17. Two symmetrically arranged rectangular grooves 16 are opened at the bottom of the housing 6, and the gear 19 is used in conjunction with the rectangular groove 16. Two symmetrically arranged racks 13 are fixedly connected to the bottom inner wall of the slide groove 12, and the racks 13 are meshed with the gear 19.

[0039] In particular, the second circular holes 18 correspond to the clamping member 5 , and the number and position are consistent.

[0040] Working principle: When the casting needs to be clamped, the casting can be placed on the operating slot 3 according to the indication of the indicating arrow 2, and the servo motor 14 is started. The output shaft of the servo motor 14 drives the bidirectional screw 11 to rotate, and the bidirectional screw 11 drives the two sliders 15 to approach each other, and the two sliders 15 drive the two shells 6 to approach each other. At this time, the insertion rod 8 is always inside the second circular hole 18, and the rotating rod 20 cannot rotate. The shell 6 drives the two installation cylinders 4 to approach each other, and the two installation cylinders 4 drive the corresponding two clamping parts 5 to approach each other, clamping the casting to facilitate subsequent processing;

[0041] When the clamping member 5 needs to be replaced, the servo motor 14 can be started again to make the two sliders 15 move away from each other. At this time, the second circular hole 18 is disengaged from the insertion rod 8. When the two housings 6 move away from each other, due to the setting of the overrunning clutch 17, the two rotating rods 20 will not rotate. When the two housings 6 approach each other again, the rack 13 drives the gear 19 to rotate, the gear 19 drives the rotating rod 20 to rotate, the rotating rod 20 drives the installation cylinder 4 to rotate, and the installation cylinder 4 drives the clamping member 5 to rotate. Since the shapes and sizes of the multiple clamping members 5 are different, the clamping member 5 can be adjusted to a position suitable for the casting, thereby improving the scope of application of the device.

[0042] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
