[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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 creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 、 Figure 2 and Figure 5, an embodiment provided by the present utility model: a chip-splitting stepped combined grooving tool, which includes a tool shank 1. A fixing groove 3 is opened on the left side of the tool shank 1, and a locking mechanism 2 is arranged at the rear side of the tool shank 1. The inner wall of the fixing groove 3 is fixedly connected with a grooving tool 4 through the locking mechanism 2. A plurality of fixing screws 5 are equidistantly threadedly connected to the rear side of the top wall and the front side of the bottom wall of the grooving tool 4. A plurality of limiting grooves 6 are equidistantly opened on the front side of the top wall and the rear side of the bottom wall of the grooving tool 4. A cutting head 7 is arranged on the inner wall of each of the plurality of limiting grooves 6. The adjacent ends of the plurality of fixing screws 5 are respectively threadedly connected to the adjacent sides of the plurality of cutting heads 7. A plurality of stress-relieving rods 8 are equidistantly fixedly connected to the top left and bottom right sides of the grooving tool 4. A plurality of water outlet holes 9 are equidistantly opened at the top and bottom ends of the grooving tool 4;

[0033] Specifically, the tool shank 1 is used to connect to the machine tool, providing support and power transmission for the entire grooving tool 4. The fixing groove 3 and the locking mechanism 2 cooperate with each other to firmly fix the grooving tool 4 on the tool shank 1, ensuring that the grooving tool 4 will not loosen or fall off during the working process. The plurality of cutting heads 7 on the grooving tool 4 are the main components for cutting work. When the machine tool drives the tool shank 1 to rotate, the grooving tool 4 rotates at a high speed accordingly. The cutting heads 7 contact the workpiece during rotation and perform cutting processing on the workpiece. Since the plurality of cutting heads 7 are combined, chip-splitting cutting can be achieved, improving the cutting efficiency. On the one hand, the fixing screws 5 fix the cutting heads 7 on the grooving tool 4, ensuring the stability of the cutting heads 7 during work. On the other hand, through the threaded connection method, it is convenient to replace and adjust each cutting head 7 separately. The limiting grooves 6 play a role in limiting and positioning the cutting heads 7, ensuring that the cutting heads 7 are installed in the correct positions. The stress-relieving rods 8 play a role in releasing stress during the cutting process. When the cutting heads 7 cut the workpiece, certain stress will be generated. The stress-relieving rods 8 can disperse these stresses, reducing the deformation and damage of the grooving tool 4. The function of the water outlet holes 9 is to spray coolant during the cutting process, which can reduce the temperature of the cutting area, reduce tool wear, and at the same time wash away the chips, keeping the cutting area clean. Through multiple grooving tools 4, efficient and stable cutting processing of multiple grooves can be achieved simultaneously, improving the processing efficiency.

[0034] Referring to Figure 1 , Figure 3 and Figure 4 , the locking mechanism 2 includes a bolt fixing plate 201. A long bolt 202 is fixedly connected to the middle of the front side of the bolt fixing plate 201. Short bolts 203 are fixedly connected to the left and right ends of the front side of the bolt fixing plate 201. A bolt limiting plate 204 is fixedly connected to the left side near the front side of the tool shank 1. Short grooves 205 are opened at the left and right ends of the rear side of the bolt limiting plate 204. A bolt hole 206 is opened in the middle of the rear side of the bolt limiting plate 204. The two short bolts 203 are respectively clamped in the two short grooves 205. The long bolt 202 penetrates through the inner wall of the bolt hole 206, and a fixing nut 207 is threadedly connected to the front end of the long bolt 202;

[0035] Specifically, the long bolt 202 and the short bolt 203 on the bolt fixing plate 201 cooperate with the bolt limiting plate 204 on the tool handle 1 to fix the grooving tool 4. During installation, the bolt fixing plate 201 is placed at the rear side of the tool handle 1, and the two short bolts 203 are respectively inserted into the short grooves 205 at the left and right ends at the rear side of the bolt limiting plate 204 to play a role in preliminary positioning. At the same time, the long bolt 202 passes through the bolt hole 206 in the middle at the rear side of the bolt limiting plate 204, and a fixing nut 207 is screwed into the front end of the long bolt 202. As the fixing nut 207 is tightened, the bolt fixing plate 201 is gradually pulled towards the bolt limiting plate 204, thereby generating a clamping force on the grooving tool 4 placed in the fixing groove 3 and firmly fixing the grooving tool 4 on the tool handle 1. During the working process, this locking method can ensure that the grooving tool 4 will not loosen or displace due to high-speed rotation and cutting force, guaranteeing the stability and precision of the cutting process.

[0036] Refer to Figure 1 and Figure 5 , a plurality of anti-slip grooves 10 are equidistantly arranged in the middle of the outer wall of the tool handle 1, and the plurality of anti-slip grooves 10 are arranged in an equidistant array; a plurality of clamping strips 11 are fixedly connected to the right side of the outer wall of the tool handle 1, and the plurality of clamping strips 11 are fixedly connected in a surrounding manner to the outer wall of the clamping strip 11; a connecting head 12 is fixedly connected to the outer side of the right end of the tool handle 1, and the connecting head 12 is engaged with the driving end;

[0037] Specifically, the anti-slip grooves 10 increase the friction when holding the tool handle 1, prevent the tool handle 1 from slipping out of the hand, and improve the stability during taking. When the tool handle 1 is connected by a clamping method, the surrounding clamping strips 11 can increase the clamping stability and firmness, and at the same time can better fit with the clamping mechanism, disperse the clamping force, reduce the local pressure on the tool handle 1, thereby extending the service life of the tool handle 1. The connecting head 12 is used to engage with the driving end to realize the connection between the tool handle 1 and the driving device, and transmit the power of the driving device to the grooving tool 4, so that the grooving tool 4 can rotate at high speed for cutting work.

[0038] Refer to Figure 3 , Figure 4 and Figure 5 , a round head 13 is fixedly connected to the front end of the fixing nut 207, and the outer surface of the round head 13 is smooth; a vacuum adsorption groove 14 is opened in the middle of the right end of the tool handle 1, and the vacuum adsorption groove 14 is another driving method; inclination angles are provided at the cutting parts of the plurality of cutting heads 7, and the angles of the cutting parts of the plurality of cutting heads 7 are all acute angles;

[0039] Specifically, the round head 13 at the front end of the fixing nut 207 is smoothed to reduce the risk of scratching the operator during operation. The vacuum adsorption groove 14, as another driving method, can be connected to a vacuum device, and the tool holder 1 can be firmly fixed on the device by using the vacuum adsorption force. The cutting part of the tool tip 7 is set at an acute angle inclination, which can make the tool tip 7 sharper during the cutting process, reduce the cutting force, improve the cutting efficiency, reduce the concentration of cutting force and heat, and extend the service life of the tool tip 7.

[0040] Working principle: The tool holder 1 is used to connect to the machine tool, providing support and power transmission for the entire grooving tool 4. The fixing groove 3 and the locking mechanism 2 cooperate with each other to firmly fix the grooving tool 4 on the tool holder 1, ensuring that the grooving tool 4 will not loosen or fall off during operation. The multiple tool tips 7 on the grooving tool 4 are the main components for cutting work. When the machine tool drives the tool holder 1 to rotate, the grooving tool 4 rotates at high speed accordingly. The tool tip 7 contacts the workpiece during rotation and performs cutting processing on the workpiece. Since multiple tool tips 7 are combined, chip splitting cutting can be achieved, improving the cutting efficiency. The fixing screw 5 fixes the tool tip 7 on the grooving tool 4 on the one hand, ensuring the stability of the tool tip 7 during work, and on the other hand, facilitating the replacement and adjustment of each tool tip 7 respectively through a threaded connection. The limiting groove 6 plays a role in limiting and positioning the tool tip 7, ensuring that the tool tip 7 is installed in the correct position. The stress releasing rod 8 plays a role in releasing stress during the cutting process. When the tool tip 7 cuts the workpiece, certain stress will be generated, and the stress releasing rod 8 can disperse these stresses, reducing the deformation and damage of the grooving tool 4. The function of the water outlet hole 9 is to spray coolant during the cutting process, which can reduce the temperature of the cutting area, reduce tool wear, and at the same time wash away the chips, keeping the cutting area clean.

[0041] Moreover, the grooving tool 4 is fixed by the cooperation of the long bolt 202 and the short bolt 203 on the bolt fixing plate 201 and the bolt limiting plate 204 on the tool holder 1. During installation, the bolt fixing plate 201 is placed at the rear side of the tool holder 1, and the two short bolts 203 are respectively inserted into the short grooves 205 at the left and right ends at the rear side of the bolt limiting plate 204 to play a role in preliminary positioning. At the same time, the long bolt 202 passes through the bolt hole 206 in the middle at the rear side of the bolt limiting plate 204, and the fixing nut 207 is screwed into the front end of the long bolt 202. As the fixing nut 207 is tightened, the bolt fixing plate 201 is gradually pulled towards the bolt limiting plate 204, thereby generating a clamping force on the grooving tool 4 placed in the fixing groove 3 and firmly fixing the grooving tool 4 on the tool holder 1.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
