[0002] The milling cutter disc is a tool used for metal cutting. It is usually installed on the spindle of a milling machine and is equipped with a non-reground inlaid carbide blade. As an important component of mechanical processing, the design and material of the milling cutter disc are directly related to the processing efficiency and product quality. With the development of technology, modern milling cutter discs have been greatly improved in terms of materials, structure and efficiency, meeting the needs of modern high-efficiency and high-precision processing. Simplifying the docking method of the milling cutter disc to achieve automatic docking and fixation is also an important step in the work. The existing docking and fixation of the milling cutter disc requires cumbersome steps such as alignment, rotation and pressing, which needs some improvements.

[0003] Therefore, it is necessary to design an automatic docking milling cutter disc with strong practicality and good docking and fixing effect. Utility Model Content

[0004] The utility model aims to provide an automatic docking milling cutter disc to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic docking milling cutter disc comprises a cutter head, one side of the cutter head is fixedly connected to a cutter handle, one end of the cutter handle is fixedly connected to a fixing rod, a wedge block 2 is fixedly connected to the surface of the fixing rod, a fixing frame is provided on the surface of the cutter handle, an extension frame is provided on one side of the fixing frame, the extension frame is adapted to the fixing rod, a plurality of connecting rods are slidably connected inside the fixing frame, a wedge block 1 is fixedly connected to one end of the connecting rod, a spring is fixedly connected to the surface of the wedge block 1, the spring is sleeved on the surface of the connecting rod to maintain a clearance fit, the other end of the spring is fixed to the inner wall of the fixing frame, one end of the wedge block 1 is fixedly connected to an embedding block, the embedding block is a trapezoidal column, a slot is provided on the surface of the fixing rod, the size and shape of the embedding block are adapted to the slot, and a disassembly mechanism is provided on the surface of the fixing rod.

[0006] According to the above technical solution, the disassembly mechanism includes an inclined sliding block, and the inclined sliding block is slidably connected to the surface of the fixed rod.

[0007] According to the above technical solution, a shockproof ring is provided on one side of the fixing frame, and the shockproof ring is slidably connected to the knife handle.

[0008] According to the above technical solution, a groove is provided on the surface of the handle.

[0009] According to the above technical solution, one end of the connecting rod is fixedly connected to a limiting block.

[0010] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0011] (1) By setting a wedge assembly, align the tool handle with the fixed frame and press the fixed frame to Figure 2 The direction is based on the principle that wedge block 1 is located at the upper side of wedge block 2. With the pressure, the lower side inclined surface of the wedge block contacts the upper guide inclined surface of the wedge block 2, and the wedge block 1 drives the connecting rod fixed at one end to slide to the outside of the fixed frame. When it moves to the lower side of the wedge block 2, the spring is fixed to the inner wall of the fixed frame and one side of the wedge block 1, and the wedge block 1 is pushed to the surface of the fixed rod by the rebound force of the spring. At this time, the upper side plane of the wedge block 1 contacts and the lower side plane of the wedge block 2, and the embedded block on one side of the wedge block 1 is just inserted into the groove on the surface of the fixed rod to complete the fixation. At this time, the upper side plane of the embedded block contacts and the upper side plane of the inner wall of the groove, and the lower side of the embedded block is adapted to the lower inclined surface of the inner wall of the groove. This docking structure can be fixed by simple plugging, which can realize automatic docking and fixation of the machine and the tool handle. The structure is simple and stable, which increases work efficiency.

[0012] (2) A disassembly mechanism is provided, which is a mechanism for separating the knife handle from the fixed frame. Since the insert is also a trapezoidal column, the shape of the slot is adapted thereto. The fixed frame is pressed again, and the insert slides out of the slot, first contacts the upper inclined surface of the inclined slider, and is then pushed back by the protrusion in the middle of the inclined slider. As the pressing continues, when the insert moves to the lower inclined surface of the inclined slider, the elastic force of the spring rebounds to make wedge block 1 press against the lower inclined surface of the inclined slider, and the knife handle is fixed to pull the fixed frame. Wedge block 1 moves with the inclined slider to press against the lower side surface of wedge block 2. Since the knife handle is fixed and the inclined slider has been restricted by wedge block 2, the fixed frame is continued to be pulled at this time. Wedge block 1 drives the connecting rod to slide to the outside of the fixed frame, and the knife handle, the fixing rod, the wedge block 2 and other components can be pulled out as a whole.

[0013] (3) An anti-vibration ring is provided to prevent the handle from being exposed for too long and causing vibration, thereby protecting the stability of the handle fixing structure. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a technical solution: an automatic docking milling cutter disc, including a cutter head 1, a cutter head 1 is fixedly connected to a cutter handle 2 on one side, a fixed rod 13 is fixedly connected to one end of the cutter handle 2, a wedge block 12 is fixedly connected to the surface of the fixed rod 13, a fixed frame 4 is provided on the surface of the cutter handle 2, an extension frame 5 is provided on one side of the fixed frame 4, the extension frame 5 is adapted to the fixed rod 13, a plurality of connecting rods 7 are slidably connected inside the fixed frame 4, a wedge block 9 is fixedly connected to one end of the connecting rod 7, a spring 8 is fixedly connected to the surface of the wedge block 9 on one side, the spring 8 is sleeved on the surface of the connecting rod 7 to maintain a clearance fit, the other end of the spring 8 is fixed to the inner wall of the fixed frame 4, an embedded block 10 is fixedly connected to one end of the wedge block 9, the embedded block 10 is a trapezoidal column, a card slot 14 is provided on the surface of the fixed rod 13, the embedded block 10 is adapted to the card slot 14 in size and shape, and a disassembly mechanism is provided on the surface of the fixed rod 13.

[0020] Specifically, the handle 2 is aligned with the fixing frame 4, and the fixing frame 4 is pressed to Figure 2 When the lever 14 is in the locked position, the spring 8 is pressed against the locking cam 14, and the spring 8 is pressed against the locking cam 14, so that the lever 14 is in the locked position and the locking cam 14 is in the locked position.

[0021] The disassembly mechanism includes an inclined sliding block 11 , and the inclined sliding block 11 is slidably connected to the surface of a fixing rod 13 .

[0022] Specifically, the disassembly mechanism is a mechanism for separating the knife handle from the fixing frame 4. Since the insert block 10 is also a trapezoidal column, the shape of the slot 14 is adapted thereto. The fixing frame 4 is pressed again, and the insert block 10 slides out of the slot 14, first contacts the upper inclined surface of the inclined sliding block 11, and is then pushed back by the protrusion in the middle of the inclined sliding block 11. As the pressing continues, when it moves to the lower inclined surface of the inclined sliding block 11, the elastic force of the spring 8 rebounds to make the wedge block 19 press against the lower inclined surface of the inclined sliding block 11, and the knife handle 2 is fixed to pull the fixing frame 4. The wedge block 19 moves with the inclined sliding block 11 to press against the lower side surface of the wedge block 2 12.

At this time, the fixing frame is continued to be pulled, and the wedge block 19 drives the connecting rod 7 to slide to the outside of the fixing frame 4, so that the knife handle 2 together with the fixing rod 13 and the wedge block 2 12 and other components can be pulled out as a whole.

[0023] A shockproof ring 3 is provided on one side of the fixing frame 4 , and the shockproof ring 3 is slidably connected to the handle 2 .

[0024] Specifically, the shockproof ring 3 is used to prevent the handle 2 from being exposed outside for too long and causing vibration, and is used to protect the stability of the handle fixing structure.

[0025] A groove 15 is provided on the surface of the knife handle 2 .

[0026] Specifically, the groove 15 makes it easier for workers to take the knife handle, thereby reducing the possibility of work accidents.

[0027] One end of the connecting rod 7 is fixedly connected to the limiting block 6 .

[0028] Specifically, the limit block 6 is used to prevent the connecting rod 7 from sinking into the inner wall of the fixing frame 4 due to excessive resilience of the spring 8, resulting in jamming, thereby reducing accidents.
