Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a cutter assembly with a replaceable cutting edge. Background Technology

[0002] A retaining member is a component commonly used in fields such as construction and industrial equipment support. Retaining members mainly serve to bear, support, and fix related components or structures, providing stable support for various devices.

[0003] Traditional mounting blades use a fixed structure, making it impossible to remove the mounting blade from the support frame. When mounting tubes with different cross-sectional shapes are required, it is not possible to change the mounting blade according to the needs, resulting in poor flexibility. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a replaceable cutting edge component.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A replaceable cutting edge ferrule assembly includes a support frame, a mounting edge, a wedge-shaped pressure block, and a wedge-shaped insert. The support frame has a mounting groove, and square grooves are formed on both sides of the inner wall of the mounting groove. A threaded hole is formed at the top of the square groove. The mounting edge is located in the mounting groove. Limiting grooves are formed on both sides of the mounting edge, and the wedge-shaped insert is inserted into the limiting groove. The threaded hole has an internal thread that passes through a threaded rod. A knob is provided at one end of the threaded rod, and the other end of the threaded rod is rotatably connected to a wedge-shaped pressure block. The wedge-shaped pressure block is located in the mounting groove, and the wedge-shaped pressure block presses down to limit the wedge-shaped insert.

[0006] In addition, a preferred structure is that support blocks are fixedly installed at all four corners of the mounting groove, and the top surface of the support blocks is in close contact with the bottom surface of the mounting blade.

[0007] Furthermore, a preferred structure is that a rotating groove is formed on the top surface of the wedge-shaped pressure block.

[0008] In addition, a preferred structure is that a rotating column is provided at one end of the threaded rod, and the rotating column rotates within the rotating groove.

[0009] In addition, a preferred structure is that a bottom sliding groove is formed on the bottom surface of the square groove, and side sliding grooves are formed on both sides of the square groove.

[0010] In addition, a preferred structure is that a slider is provided on the bottom surface of the wedge-shaped insert, and the slider slides within the bottom groove.

[0011] In addition, a preferred structure is that sliders 2 are provided on both sides of the wedge-shaped pressure block, and sliders 2 slide within the side grooves.

[0012] The beneficial effects of this utility model are as follows: In this invention, the mounting blade can be freely removed from the mounting slot of the support frame, and the mounting blade can be freely replaced with a matching one according to the actual cross-sectional shape of the mounting tube, which provides high flexibility.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-8A replaceable cutting edge component includes a support frame 1, a mounting edge 2, a wedge-shaped pressure block 4, and a wedge-shaped insert 5. The support frame 1 has a mounting groove 11, and square grooves 12 are formed on both sides of the inner wall of the mounting groove 11. A threaded hole 13 is formed at the top of the square groove 12. The mounting edge 2 is located in the mounting groove 11. Limiting grooves 21 are formed on both sides of the mounting edge 2, and the wedge-shaped insert 5 is inserted into the limiting grooves 21. The threaded hole 13 has an internal thread that passes through the threaded rod 3. A knob 31 is provided at one end of the threaded rod 3, and the other end of the threaded rod 3 is rotatably connected to the wedge-shaped pressure block 4. The wedge-shaped pressure block 4 is located in the mounting groove 11, and the wedge-shaped pressure block 4 presses down to limit the wedge-shaped insert 5.

[0017] Meanwhile, support blocks 6 are fixedly installed at all four corners of the mounting slot 11. The top surface of the support block 6 is in close contact with the bottom surface of the mounting edge 2, and the support block 6 provides support for the mounting edge 2.

[0018] Furthermore, a rotating groove 41 is provided on the top surface of the wedge-shaped pressure block 4, and a rotating column 32 is provided at one end of the threaded rod 3. The rotating column 32 rotates within the rotating groove 41, so that the threaded rod 3 and the wedge-shaped pressure block 4 are rotatably connected. When the threaded rod 3 rotates, it drives the wedge-shaped pressure block 4 to move.

[0019] Furthermore, a bottom sliding groove 121 is provided on the bottom surface of the square groove 12, and side sliding grooves 122 are provided on both sides of the square groove 12.

[0020] Meanwhile, a slider 51 is provided on the bottom surface of the wedge-shaped insert 5. The slider 51 slides within the bottom groove 121 and provides guidance for the movement of the wedge-shaped insert 5.

[0021] Furthermore, sliders 42 are provided on both sides of the wedge-shaped pressure block 4. The sliders 42 slide within the side groove 122 and provide guidance for the movement of the wedge-shaped pressure block 4.

[0022] In this embodiment, when it is necessary to replace the mounting edge 2, the knob 31 is turned to drive the threaded rod 3 to rotate synchronously. The threaded rod 3 rotates in the threaded hole 13, causing the threaded rod 3 to gradually move upward. Since the threaded rod 3 and the wedge-shaped pressure block 4 are rotatably connected, the wedge-shaped pressure block 4 will also move upward. At this time, the wedge-shaped pressure block 4 cancels the downward pressure limit on the wedge-shaped insert 5. Then, the mounting edge 2 is pushed forcefully, and the mounting edge 2 squeezes the wedge-shaped insert 5. The wedge-shaped insert 5 leaves the limiting groove 21 and enters the square groove 12. At this time, the mounting edge 2 can be removed. Next, insert another mounting blade 2 into the mounting groove 11, turn the knob 31 to drive the threaded rod 3 to rotate synchronously, thereby driving the wedge-shaped pressure block 4 to move down. The wedge-shaped pressure block 4 moves down and squeezes the wedge-shaped insert 5 to move, so that one end of the wedge-shaped insert 5 is inserted into the limiting groove 21. At this time, the replacement of the mounting blade 2 can be completed.

[0023] In this utility model, the mounting blade 2 can be freely removed from the mounting slot 11 of the support frame 1, and the mounting blade 2 can be freely replaced according to the cross-sectional shape of the actual mounting tube, which is highly flexible.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
