[0002] The pulley groove cutter is a tool used to process the pulley groove, which is usually used in the field of metal processing. Its function is to cut a groove on the pulley so that the belt can be smoothly embedded in it, thereby achieving the purpose of transmission. When processing the pulley groove, the blank is fixed to the fixed end of the rotating mechanism, and the blank is driven to rotate by rotation, and the groove cutter at one end of the transmission mechanical arm is controlled to approach the position of the blank and complete the cutting, so that the pulley groove can be processed. When the pulley groove cutter is connected to the transmission mechanical arm, it usually needs to be installed and fixed with a slot and bolts, which is time-consuming and labor-intensive during installation, and is not flexible and convenient to use. In addition, the cutter head is a consumable part and needs to be replaced frequently. The cutter head and the handle or blade are usually an integrated structure, and are usually replaced as a whole when replaced, which leads to the unified replacement of the cutter head and the handle or blade, resulting in high cost expenditure.

[0017] In this embodiment: the cutter head 1 uses the blade 11 to process the cutting wheel groove of the blank, the cutter head 1 is separately connected to the blade body 2 through the convex connecting block 12, and the blade body 2 is connected and fixed to the transmission mechanical arm through the connecting plate 21. The limiting slide groove 22 guides and limits the convex connecting block 12 to slide, so that the convex connecting block 12 can maintain a stable sliding action, prevent the convex connecting block 12 from driving the cutter head 1 to tilt and deflect, and enable the convex connecting block 12 to drive the cutter head 1 to achieve The blade 2 supports and protects the limiting wedge 3 from the outside, and the first spring 31 elastically pushes the limiting wedge 3 so that the limiting wedge 3 can slide toward the convex connecting block 12. The convex connecting block 12 is docked with the limiting wedge 3 through the triangular limiting slot 121. When the convex connecting block 12 and the limiting slot 22 are installed, the convex connecting block 12 contacts the top of the limiting wedge 3. The limiting wedge 3 uses the inclined surface to enable the convex connecting block 12 to limit The wedge block 3 is squeezed and retracted, so that the convex connecting block 12 can continue to fall. When the triangular limiting slot 121 corresponds to the position of the limiting wedge block 3, the limiting wedge block 3 is no longer limited by the convex connecting block 12, so that the first spring 31 can push the limiting wedge block 3 into the triangular limiting slot 121, so that the limiting wedge block 3 can limit the convex connecting block 12 through the triangular limiting slot 121. At this time, the convex connecting block 12 drives the cutter head 1 to be firmly locked in the limiting slot 22, so that The convex connecting block 12 can stably drive the cutter head 1 for use. When the cutter head 1 is disassembled and replaced, the vertical plate 33 is pulled, and the vertical plate 33 drives the pull rod 32 to pull the limiting wedge block 3, so that the limiting wedge block 3 can be separated from the convex connecting block 12, thereby enabling the cutter head 1 to be disassembled. When installing the cutter head 1, it is only necessary to insert the convex connecting block 12 into the limiting slide groove 22 to complete the locking. The installation is convenient and quick, which improves the installation efficiency, and does not require overall replacement, thereby reducing cost expenditure.

[0018] A top groove 231 corresponding to the give-way groove 23 is provided at the top of the blade body 2, and a flap 331 is hinged at the top of the vertical plate 33, and the flap 331 is snap-connected to the inner wall of the top groove 231; the give-way groove 23 and the top groove 231 give way to the vertical plate 33 and the flap 331, which is convenient for the staff to control the flap 331 by hand, and the flap 331 is snap-connected to the top groove 231 when not in use, so that the top groove 231 can limit the flap 331, prevent the flap 331 and the vertical plate 33 from shifting horizontally, and ensure the stability of the limiting wedge block 3 on the convex connecting block 12.

[0019] A torsion spring 34 is provided between the flap 331 and the vertical plate 33, and a hand-picking groove 332 is provided at the top of the flap 331, and the flap 331 is flush with the top of the blade body 2; the torsion spring 34 drives the flap 331 to flip into the top groove 231, so that the top groove 231 can stably limit the flap 331, and the staff holds the hand-picking groove 332 with their hands, thereby facilitating the flap 331 to flip upward, and the vertical plate 33 and the flap 331 do not protrude from the top of the blade body 2, thereby reducing the problem of external objects interfering with the vertical plate 33 and the flap 331.

[0020] A limiting slot 122 is provided at the bottom of the convex connecting block 12, and an insert rod 4 is slidably connected to the inner wall of the blade body 2, and the insert rod 4 is inserted into the inner wall of the limiting slot 122. The bottom end of the insert rod 4 is fixedly connected to a second spring 41, and the second spring 41 is fixedly connected to the inner wall of the blade body 2; when the convex connecting block 12 slides into the limiting slot 22, the insert rod 4 is inserted into the limiting slot 122 to guide the convex connecting block 12 in a sliding manner, and the insert rod 4 can limit the convex connecting block 12 laterally, thereby improving the limiting stability of the convex connecting block 12, and the second spring 41 pushes the insert rod 4 in an upward direction so that the insert rod 4 can push the convex connecting block 12, and when the limiting wedge block 3 is pulled out of the triangular limiting slot 121 to release the limiting of the convex connecting block 12, the insert rod 4 can push the convex connecting block 12 to pop out of the limiting slot 22, thereby facilitating the separation work after disassembly.

[0021] Two temperature sensors 42 for detecting the temperature of the limit slot 122 are installed on the side wall of the insertion rod 4, and an alarm 43 corresponding to the temperature sensor 42 is installed on one side of the blade body 2; when the convex connecting block 12 and the blade head 1 and the blade body 2 are installed and used, the temperature sensor 42 is inside the limit slot 122, and the temperature sensor 42 detects the temperature of the convex connecting block 12 in real time. When the blade head 1 is working, the high temperature generated is transmitted to the convex connecting block 12, and the temperature of the blade head 1 is indirectly judged by performing a temperature side inspection on the convex connecting block 12. When the working temperature of the blade head 1 is too high, the temperature sensor 42 can transmit the sensing result to the alarm 43 to issue a warning voice, so that the staff can deal with the situation and avoid the situation where the blade head 1 works at a continuous high temperature and increases the loss.

[0022] The working principle and usage process of the utility model are as follows: when the cutter head 1 is disassembled and replaced, the flap 331 is driven to flip upward by holding the finger groove 332, and then the flap 331 is pulled to drive the vertical plate 33 to slide, and the vertical plate 33 drives the limiting wedge block 3 to be pulled out of the triangular limiting slot 121. At this time, the convex connecting block 12 is no longer limited by the limiting wedge block 3, and the second spring 41 pushes the insertion rod 4 to slide upward, and the insertion rod 4 can push the convex connecting block 12 to pop out to the outside of the limiting slide groove 22, which is convenient for the separation work after disassembly, thereby enabling the cutter head 1 to be disassembled. When installing the cutter head 1, it is only necessary to insert the convex connecting block 12 into the limiting slide groove 22 to complete the locking. The installation is convenient and quick, which improves the installation efficiency, and does not require overall replacement, thereby reducing cost expenditure.
