Description

Technical Field

[0001] The utility model belongs to the technical field of cutting fixtures, and particularly relates to a cutting fixture for metal parts. Background Technique

[0002] Metal cutting is a material removal and forming method in metal forming processes. The metal cutting process is a process of interaction between the workpiece and the cutting tool. The cutting tool removes excess metal from the workpiece to be machined. For example, some cylindrical metal parts need to use cutting fixtures to fix the metal parts during the cutting process.

[0003] However, some existing cutting fixtures for metal parts may be worn after long-term use, and it is inconvenient to replace the worn fixing parts after wear occurs. Summary of the Utility Model

[0004] To solve the problems existing in the prior art, the utility model provides a cutting fixture for metal parts. When the clamping block needs to be replaced, the electric hydraulic push rod drives the slider to move towards the notch of the chute, and then the rotating ring is rotated to drive the screw rod to rotate. When the screw rod and the threaded sleeve are no longer in threaded connection, the movable clamping block can drive the slider to be taken out from the notch of the chute, which is convenient for disassembly. When a new slider is placed inside the chute, the rotating ring is rotated to drive the screw rod to rotate and be in threaded connection with the threaded sleeve. At the same time, the anti-slip pattern at one end of the rotating ring contacts with one end of the threaded sleeve, playing an anti-slip role and facilitating the replacement of the clamping block.

[0005] To achieve the above object, the utility model provides the following technical solution: A cutting fixture for metal parts, including a fixed disk, circular holes are formed on the surface of the fixed disk, three chutes are formed on the surface of the fixed disk, a slider is slidably connected inside the chute, a clamping block is fixedly connected to the top end of the slider, a fixed ring is fixedly connected to the surface of the fixed disk through a connecting plate, three electric hydraulic push rods are fixedly connected inside the fixed ring, one end of the electric hydraulic push rod is rotatably connected with a screw rod, a rotating ring is fixedly connected to the surface of the screw rod, a threaded sleeve is fixedly connected to one end of the slider, and a notch is formed inside the chute.

[0006] Further, the screw rod and the threaded sleeve are internally threaded, and an anti-slip pattern is provided at one end of the rotating ring corresponding to the position of the threaded sleeve.

[0007] Further, reinforcing ribs are fixedly connected to the surfaces of both the electric hydraulic push rod and the fixed disk.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] When it is necessary to replace the clamping block, the slider is driven by the electro-hydraulic push rod to move towards the notch of the chute. Then, the rotating ring is rotated to drive the screw to rotate. When the screw and the threaded sleeve are no longer thread-connected, the movable clamping block can drive the slider to be taken out from the notch of the chute, which is convenient for disassembly. When a new slider is placed inside the chute, the rotating ring is rotated to drive the screw to rotate and be thread-connected with the threaded sleeve. At the same time, the anti-slip pattern at one end of the rotating ring contacts one end of the threaded sleeve, playing an anti-slip role and facilitating the replacement of the clamping block.

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0014] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. Embodiment

[0015] Refer to the attached Figure 1-2 As shown, a metal part cutting fixture includes a fixed disk 1. A round hole is provided on the surface of the fixed disk 1. Three chutes 4 are provided on the surface of the fixed disk 1. A slider 5 is slidably connected inside the chute 4. A clamping block 6 is fixedly connected to the top of the slider 5. The surface of the fixed disk 1 is fixedly connected to a fixed ring 2 through a connecting plate. Three electro-hydraulic push rods 3 are fixedly connected inside the fixed ring 2. One end of the electro-hydraulic push rod 3 is rotatably connected to a screw 7. A rotating ring 9 is fixedly connected to the surface of the screw 7. A threaded sleeve 8 is fixedly connected to one end of the slider 5. A notch is provided inside the chute 4.

[0016] The screw rod 7 is internally threadedly connected to the threaded sleeve 8, and one end of the swivel ring 9 corresponding to the position of the threaded sleeve 8 is provided with anti-slip threads.

[0017] Reinforcing ribs are fixedly connected to the surfaces of both the electric hydraulic push rod 3 and the fixed disk 1.

[0018] Working principle: When in use, place the metal part inside the circular hole of the fixed disk 1. Through the setting of the electric hydraulic push rod 3, the screw rod 7 can be driven to move. The screw rod 7 drives the threaded sleeve 8 to move, thereby driving the slider 5 to move inside the chute 4, and then driving the clamping block 6 to move to fix the part. When it is necessary to replace the clamping block 6, the electric hydraulic push rod 3 drives the slider 5 to move towards the notch of the chute 4, and then rotate the swivel ring 9 to drive the screw rod 7 to rotate. When the screw rod 7 and the threaded sleeve 8 are no longer threadedly connected, the movable clamping block 6 can drive the slider 5 to be taken out from the notch of the chute 4, which is convenient for disassembly. When the new slider 5 is placed inside the chute 4, rotate the swivel ring 9 to drive the screw rod 7 to rotate and threadedly connect with the threaded sleeve 8. At the same time, the anti-slip threads at one end of the swivel ring 9 are in contact with one end of the threaded sleeve 8, playing an anti-slip role and facilitating the replacement of the clamping block 6.
