DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 A fixing fixture for shaft parts for machining, comprising a mounting frame 1, a supporting frame 11, a horizontal plate 12 and a rotating plate 13, wherein the horizontal plate 12 is vertically fixedly mounted on the top of the supporting frame 11, the rotating plate 13 is rotatably mounted on the end of the horizontal plate 12, a three-jaw chuck 2 is rotatably mounted on the rotating plate 13, and traction components 3 are fixedly mounted on both sides of the horizontal plate 12, and the traction components 3 are connected to the rotating plate 13;

[0021] The traction assembly 3 includes a fixed seat 31, a screw rod 32, a moving block 33, a traction rod 34 and a side plate 35. The fixed seat 31 is fixedly installed at both ends of the side surface of the top of the platform, both ends of the screw rod 32 are rotatably installed on the fixed seat 31, the moving block 33 is slidably installed on the screw rod 32, and the side plates 35 are symmetrically fixedly installed on both sides of the bottom of the rotating plate 13. Both ends of the traction rod 34 are rotatably connected to the moving block 33 and the side plates 35 respectively.

[0022] The three-jaw chuck 2 includes a chuck 21 and a claw 22. The claw 22 is slidably mounted on the chuck 21. The claw 22 fixes one end of a shaft-like part. The three-jaw chuck 2 is a common prior art and will not be elaborated on again.

[0023] The clamping claw 22 includes a pushing block 221 and a fixed claw 222. The two fixed claws 222 are symmetrically hinged at the end of the pushing block 221. A buffer pad is fixedly installed between the fixed claws 222. When the shaft parts are inserted between the clamping claws 22, the fixed claws 222 are squeezed and opened. The buffer pad has the function of increasing friction and providing buffering during the process of the fixed claws 222 fixing the parts.

[0024] The rotating plate 13 is clamped with a fixed column 4, which passes through the chuck 21 and is clamped with the rotating plate 13. The fixed column 4 fixes the chuck 21. When the fixed column 4 is pulled out during production, the chuck 21 cannot rotate when the fixed column 4 is inserted.

[0025] A limiting component is installed between the horizontal plate 12 and the rotating plate 13. The limiting component is used to stabilize the rotating plate 13. The limiting component has a certain supporting effect on the rotating plate 13.

[0026] The limiting component includes a connecting rod and an elastic compression rod. The elastic compression rod is fixedly installed on the bottom surface of the horizontal plate 12. The two ends of the connecting rod are rotatably connected to the rotating plate 13 and the elastic compression rod respectively. When the rotating plate 13 is in a non-vertical state with the horizontal plate 12, the elastic compression rod is squeezed by the connecting rod and contracts, while providing certain support for the rotating plate 13.

[0027] In the utility model, during the production process, the parts are fixed by the three-jaw chuck 2, and the moving block 33 is moved on the screw rod 32 by driving the screw rod 32 to rotate, so that the traction rod 34 drives the rotating plate 13 to rotate, and the rotating plate 13 can rotate toward the support frame 11, so that when the shaft parts are processed, the fixed angle can be adjusted according to the processing requirements, so that the parts can be tilted relative to the processing equipment, thereby meeting different processing requirements.

[0028] In general, in response to the technical problem: the existing equipment uses a clamp to fix the processed shaft horizontally, and the shaft parts need to be processed at a tilted angle during the production process, and the existing equipment cannot fix them at an angle; a technical solution is adopted: the three-jaw chuck is tilted by a traction assembly; because the implementation process of the technical solution is: during the production process, the parts are fixed by the three-jaw chuck 2, and the moving block 33 is moved on the screw rod 32 by driving the screw rod 32 to rotate, so that the traction rod 34 drives the rotating plate 13 to rotate, and the rotating plate 13 can rotate toward the support frame 11; this will inevitably solve the technical problem, and the technical effect achieved is: when processing shaft parts, the fixing angle can be adjusted according to the processing requirements, so that the parts can be tilted relative to the processing equipment, thereby meeting different processing requirements.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
