Description

Technical Field

[0001] The invention relates to the technical field of water-cooling roller cutting and processing, and in particular to adaptive water-cooling roller dynamic cutting and processing equipment. Background Art

[0002] The roller is a cylindrical mechanical part currently used in industries such as papermaking, textiles, printing and metallurgy. It usually has functions such as support, transmission, guiding or calendering. Roller processing requires several core processes: pretreatment, rough machining, heat treatment, finishing, surface treatment and dynamic balancing correction. During the rough machining and finishing stages, the roller needs to be cut using a lathe to achieve the required shape and surface texture.

[0003] When cutting the end of a roller, a three-jaw chuck or other clamping device is required to clamp the roller. The clamping device drives the roller to rotate, and then a tool is used to cut the roller shaft head. However, due to the large aspect ratio of the roller, its bending resistance is weak. During the cutting process, the rotation resonance and cutting force will cause deviations at one end of the cut, resulting in a decrease in processing accuracy. The existing technology has proposed a good solution to this problem, such as a furnace roller rough machining turning device with patent announcement number CN117961105B, which is provided with three support plates and three outer clamping plates. The furnace roller is firmly clamped by the inner support and outer clamping method to ensure that the axis of the furnace roller is in line with the axis of the main shaft. At the same time, by providing auxiliary mechanisms and extension plates and other structures, the clamping stability is improved, the safety hazards in the processing process are reduced, and it can adapt to furnace rollers of different lengths, ensuring processing accuracy and efficiency, and improving the overall processing quality.

[0004] Although the existing technology solves the problem of the large aspect ratio of the roller causing the cutting end to deviate under the cutting force during cutting, resulting in a decrease in machining accuracy, the following problems still exist: the water-cooled roller mainly comprises an outer tube and a guide liner. When machining the water-cooled roller, the guide liner needs to be welded to the inside of the outer tube after machining. If the outer tube is cut first, the thermal deformation caused by cutting will cause the inner wall of the outer tube to deform, making it difficult to assemble the inner liner. The heat generated when the inner liner is welded to the inner wall of the outer tube will also cause thermal deformation of the outer wall of the outer tube. Following the principle of machining the water-cooled roller inside first and then outside can prevent the occurrence of assembly difficulties and correct the thermal deformation of the outer wall. Since the guide liner is welded to the inner wall of the water-cooled roller, it cannot be fixed by internal support and external clamping. Therefore, when cutting the non-clamped end, the water-cooled roller will still deviate under the cutting force during cutting. In addition, as the tool feed rate increases during cutting, the force exerted on the end of the water-cooled roller will gradually increase, which will further aggravate the deflection of the end of the water-cooled roller and reduce machining accuracy.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention designs an adaptive water-cooled roller dynamic cutting processing equipment. Summary of the Invention

[0006] The present invention provides an adaptive water-cooled roller dynamic cutting processing equipment, which solves the problem that the water-cooled roller needs to be welded with a guide liner first, resulting in the inability to support it from the inside, and the problem that the water-cooled roller has a large aspect ratio, so it will cause it to deviate under the cutting force when cutting at the end. By setting a multi-point clamping mechanism, it is possible to achieve multi-point uniform clamping of water-cooled rollers of different lengths, and the multi-point clamping mechanism will rotate together with the three-jaw chuck and the water-cooled roller during the cutting process to accelerate the air flow rate, so that the heat generated by the cutting can be quickly dissipated to prevent the water-cooled roller from thermal deformation. A pressure regulating component and a drive component are provided. When the tool feed cutting force increases, the drive component will be driven to move by the pressure regulating component, so that the clamping force of the three-jaw chuck and the multi-point clamping mechanism on the water-cooled roller increases with the increase of the cutting force, thereby achieving the purpose of adaptive adjustment and ensuring the stability of the water-cooled roller during the cutting process.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] An adaptive water-cooled roller dynamic cutting processing equipment, including a lathe body, a three-jaw chuck and a tool carrier; also including a multi-point clamping assembly, a pressure adjustment assembly, a drive assembly and a feed assembly; the multi-point clamping assembly includes a telescopic assembly, a connecting assembly and a clamping ring plate; the telescopic assembly is connected to the three-jaw chuck; the connecting assembly is connected to the telescopic assembly; the clamping ring plate is connected to the telescopic assembly, and when the three-jaw chuck rotates, the clamping ring plate is driven to rotate through the telescopic assembly, and when the telescopic assembly is extended and retracted, the clamping ring plate is driven to move axially; the pressure adjustment assembly is connected to the lathe body; the drive assembly is installed in the pressure adjustment assembly; the feed assembly connects the tool carrier and the pressure adjustment assembly, and the tool carrier drives the feed assembly to slide during cutting and feeding, and when the feed assembly slides, the drive assembly drives the multi-point clamping assembly to slide in the radial direction through the three-jaw chuck.

[0009] Preferably, the three-jaw chuck includes a disc body, jaws and an adjusting piece; the disc body is connected to the lathe body; the jaws are slidably mounted in a circular array on the disc body, and an adjusting slot is provided at the tail of the jaws; the adjusting piece is connected to the disc body; the telescopic assembly includes a sliding rod seat, a pneumatic push rod and a scissor rod group; a total of three sliding rod seats are provided and are respectively mounted in the adjusting slots of three different jaws; the pneumatic push rod is connected to the disc body; the scissor rod group is connected to the clamping ring plate.

[0010] In the above scheme, the pneumatic push rod can drive multiple clamping ring plates to slide through the scissor rod group, so that the multiple clamping ring plates are evenly distributed on the outer wall of the water-cooled roller. At the same time, the sliding rod seat can slide radially with the clamping claw to drive the clamping ring plate to adjust the clamping force, thereby realizing multi-point clamping. Compared with the traditional three-jaw chuck, multi-point clamping can reduce the generation of single-point stress concentration and reduce the cantilever effect caused by excessive aspect ratio; it can also adapt to water-cooled rollers of different lengths through the sliding effect, ensure that the water-cooled roller is subjected to uniform clamping force, and prevent it from bending and deforming under rotational resonance and cutting force, resulting in a decrease in processing accuracy.

[0011] Preferably, the connecting assembly includes connecting rod 1 and connecting rod 2; connecting rod 1 is connected between the pneumatic push rod and the clamping ring plate farthest from the three-jaw chuck; and connecting rod 2 is connected between two adjacent clamping ring plates farthest from the three-jaw chuck.

[0012] In the above scheme, the three groups of scissor rod groups can be moved under the push of the same pneumatic push rod through the connecting rod 2, thereby saving power source, and ensuring that the three groups of scissor rod groups move synchronously, so that the water-cooled roller can be evenly stressed when the three groups of clamping ring plates apply clamping force; the pneumatic push rod is connected to the disk body, and will rotate together with the three-jaw chuck during cutting, that is, the processed water-cooled roller, three-jaw chuck, pneumatic push rod, scissor rod group and clamping ring plate rotate synchronously to avoid motion interference.

[0013] Preferably, the connecting rod 1 is a telescopic structure; the connecting rod 2 includes an outer rod, an inner rod and a preload spring; the outer rod is connected to the clamping ring plate; the inner rod is slidably installed in the outer rod; and the preload spring is connected between the outer rod and the inner rod.

[0014] In the above scheme, connecting rod one and connecting rod two are retractable to ensure that when clamping water-cooled rollers of different diameters, the positions of the three sets of clamping ring plates can be freely adjusted in the radial direction; the pre-tightening spring can create a mutual tensioning force between the inner rod and the outer rod. When the three sets of clamping ring plates are all subjected to pre-tightening force, the clamping ring plates will generate an elastic clamping force on the water-cooled roller, thereby absorbing rotational resonance and ensuring the stability of the water-cooled roller during cutting.

[0015] Preferably, the clamping ring plate includes a sliding end, a guide vane and a clamping end; the sliding end is slidably mounted on a sliding rod seat; the guide vane is connected to the sliding end; the clamping end is connected to the guide vane, and the contact surface between the clamping end and the workpiece is made of silicone rubber.

[0016] In the above scheme, during the cutting process, the clamping ring plate will rotate together with the water-cooled roller and the three-jaw chuck. At this time, the guide vane will accelerate the air flow rate on the surface of the water-cooled roller, so that the water-cooled roller can quickly dissipate heat during the cutting process, thereby reducing the processing error caused by thermal deformation; the contact surface of the clamping end is made of silicone rubber material, which can better adapt to water-cooled rollers of different diameters and ensure that it fully fits their surface, thereby cooperating with the rigid contact of the three-jaw chuck to provide stable clamping force.

[0017] Preferably, the sliding rod seat includes an adjustment seat, a sliding hole and a sliding rod; the adjustment seat is installed in the adjustment groove, and the adjustment groove and the adjustment seat are provided with fixing screw holes of the same specifications; the sliding hole is provided on the adjustment seat; the sliding rod is slidably installed in the sliding hole, and the end of the sliding rod is fixedly connected to the clamping ring plate farthest from the three-jaw chuck.

[0018] In the above scheme, the position of the adjustment seat is adjusted by sliding the adjustment seat in the adjustment groove, so that the adjustment seat can adapt to different clamping layers of the claws, thereby better adapting to water-cooled rollers of different diameters, and the sliding rod can slide freely following the clamping ring plate, changing the clamping position according to the different lengths of water-cooled rollers, ensuring that there will be no collision with the tool during the cutting process, thereby ensuring normal cutting.

[0019] Preferably, the pressure regulating assembly includes a pressure chamber, a rotating chamber, an regulating piston and an regulating spring; the pressure chamber is arranged on the lathe body; the rotating chamber is rotationally connected to the pressure chamber and is connected to the three-jaw chuck; the regulating piston is connected to the pressure chamber, and an axial groove is provided on the regulating piston; the regulating spring is connected between the regulating piston and the pressure chamber.

[0020] In the above scheme, the cutting force generated by the tool carrier on the water-cooled roller will increase when feeding. At this time, the tool carrier will drive the adjusting piston to slide through the feeding assembly during the sliding process. The adjusting piston compresses the water filled in the pressure chamber and presses it toward the rotating chamber. The driving assembly in the rotating chamber is pressurized to cause the adjusting part to rotate, and the rotation direction of the adjusting part is the clamping direction of the claw. At this time, the claw and the multi-point clamping assembly will increase the clamping force on the water-cooled roller to cope with the increased cutting force.

[0021] Preferably, the feed assembly includes a transverse groove, an axial connecting rod, a locking screw hole and a locking bolt; the transverse groove is provided on the tool carrier; one end of the axial connecting rod is slidably installed in the transverse groove, and the other end is slidably installed in the axial groove, and a connecting screw hole is provided at one end of the transverse groove; the locking screw hole is provided on the tool carrier; the locking bolt is installed on the locking screw hole, and during cutting, the locking bolt is simultaneously installed in the locking screw hole and the connecting screw hole.

[0022] In the above scheme, before feeding, the tool carrier is allowed to adjust its position freely, and the adjusting piston will not slide during the process. When the tool carrier is adjusted to the required position, since the locking screw hole and the connecting screw hole are always on the same axis, it is only necessary to tighten the locking bolt and screw the locking bolt into the locking screw hole and the connecting screw hole at the same time to ensure that the tool carrier will drive the adjusting piston to move in the feeding direction when feeding.

[0023] Preferably, the driving assembly includes a ring plug, a pressure spring, a driving rack and a driving gear; the ring plug is slidably installed in the rotating chamber; the pressure spring is connected between the ring plug and the rotating chamber; the rotating chamber is provided with a rack groove; the driving rack is connected to the ring plug and slidably installed in the rack groove; the driving gear is connected to the adjusting member.

[0024] In the above scheme, since the adjusting part will drive the claw to move radially when rotating, helping the claw to clamp the water-cooled roller, when feeding, the adjusting piston will slide in the pressure chamber, pressing the water in the pressure chamber into the rotating chamber, thereby generating pressure on the ring plug. The pressure on the ring plug will compress the pressure spring. At this time, the driving rack will slide in the rack groove. When it slides into contact with the driving gear, it will squeeze the driving gear, causing the driving gear to drive the adjusting part to rotate, thereby increasing the clamping force of the claw and the multi-point clamping assembly on the water-cooled roller, ensuring that the water-cooled roller remains stable during the cutting process.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. Compared with the existing water-cooled roller cutting processing equipment, the present invention sets a multi-point clamping mechanism, which can reduce the generation of single-point stress concentration and reduce the cantilever effect caused by the excessive aspect ratio by multi-point clamping; it can also adapt to water-cooled rollers of different lengths through the sliding effect, and the scissor rod group can automatically distribute the clamping ring plates evenly on the water-cooled roller, ensuring that the water-cooled roller is subjected to uniform clamping force, preventing it from bending and deforming under rotational resonance and cutting force, resulting in a decrease in processing accuracy; each group of clamping ring plates is connected by a retractable connecting rod 2, which can move radially with the clamping claws while ensuring that the three groups of clamping ring plates will not deviate, thereby ensuring that the axis of the water-cooled roller and the axis of the three-jaw chuck always remain coincident, and when the three groups of clamping ring plates are all subjected to the pre-tightening force generated by the pre-tightening spring, the clamping ring plates will generate elastic clamping force on the water-cooled roller, thereby absorbing rotational resonance and ensuring the stability of the water-cooled roller during cutting.

[0027] 2. The present invention designs the clamping ring plate into a sliding end, a guide vane and a clamping end. During the cutting process, the clamping ring plate will rotate together with the water-cooled roller and the three-jaw chuck. At this time, the guide vane will accelerate the air flow rate on the surface of the water-cooled roller and cooperate with the spraying of the cutting fluid to accelerate the flow of the cutting fluid on the surface of the water-cooled roller, so that the water-cooled roller can quickly dissipate heat during the cutting process, thereby reducing the processing error caused by thermal deformation; the contact surface of the clamping end is made of silicone rubber material, which can better adapt to water-cooled rollers of different diameters and specifications, ensuring that it fully fits its surface without causing the surface of the water-cooled roller to be crushed, thereby cooperating with the rigid contact of the three-jaw chuck to provide stable clamping force.

[0028] 3. The present invention sets a pressure regulating component, a driving component and a feeding component. When cutting is not in progress, the tool carrier can move freely without causing the pressure component and the driving component to move. When cutting starts, the feeding component connects the tool carrier and the pressure regulating component, so that when the tool is fed, the tool carrier will cause the regulating piston to press the water in the pressure chamber into the rotating chamber, thereby driving the ring plug to slide. The sliding of the ring plug drives the driving rack to squeeze the driving gear, so that the driving gear drives the adjusting part to rotate, thereby increasing the clamping force of the claws and the multi-point clamping component on the water-cooled roller, and the clamping force will increase with the increase of the cutting force, ensuring that the water-cooled roller remains stable during the cutting process.

[0043] As a specific embodiment of the present invention, refer to Figure 1 、 Figure 2 and Figure 3 The three-jaw chuck 2 includes a disc body 21, claws 22 and an adjusting member 23; the disc body 21 is connected to the lathe body 1; the claws 22 are slidably mounted on the disc body 21 in a circular array, and an adjusting slot 221 is provided at the tail of the claws 22; the adjusting member 23 is connected to the disc body 21; the telescopic assembly 41 includes a sliding rod seat 411, a pneumatic push rod 412 and a scissor rod group 413; the sliding rod seat 411 is provided with three in total and is respectively installed in the adjusting slots 221 of three different claws 22; the pneumatic push rod 412 is connected to the disc body 21, and a power supply is provided inside the pneumatic push rod 412, and no external power supply is required to avoid winding during cutting rotation; the scissor rod group 413 is connected to the clamping ring plate 43. The scissor rod group 413 has a larger contraction ratio than the cylindrical rod telescopic structure, and through the cross The triangular stabilizing unit formed by the fork can withstand axial pressure, lateral shear force and torque at the same time, and its lateral stability is better during rotational cutting, that is, it is not easy to cause radial deformation; the pneumatic push rod 412 can drive multiple clamping ring plates 43 to slide through the shear rod group 413, so that the multiple clamping ring plates 43 are evenly distributed on the outer wall of the water-cooled roller, and at the same time, the sliding rod seat 411 can slide radially with the clamping claw 22 to drive the clamping ring plate 43 to adjust the clamping force, thereby realizing multi-point clamping. Compared with the traditional three-jaw chuck 2, multi-point clamping can reduce the generation of single-point stress concentration and reduce the cantilever effect caused by excessive aspect ratio; it can also adapt to water-cooled rollers of different lengths through the sliding effect, ensure that the water-cooled roller is subjected to uniform clamping force, and prevent it from bending and deforming under rotation resonance and cutting force, resulting in a decrease in processing accuracy.

[0044] As a specific embodiment of the present invention, refer to Figure 2 and Figure 3 The connecting assembly 42 includes a first connecting rod 421 and a second connecting rod 422. The first connecting rod 421 is connected between the pneumatic push rod 412 and the clamping ring plate 43 farthest from the three-jaw chuck 2. The second connecting rod 422 is connected between two adjacent clamping ring plates 43 farthest from the three-jaw chuck 2. The second connecting rod 422 allows the three scissor rod groups 413 to move under the push of the same pneumatic push rod 412, thereby saving power and ensuring that the three scissor rod groups 413 move synchronously, so that the water-cooled roller is evenly stressed when the three clamping ring plates 43 apply clamping force. The pneumatic push rod 412 is connected to the disc body 21 and rotates together with the three-jaw chuck 2 during cutting. That is, the processed water-cooled roller, three-jaw chuck 2, pneumatic push rod 412, scissor rod groups 413, and clamping ring plates 43 rotate synchronously to avoid motion interference.

[0045] As a specific embodiment of the present invention, refer to Figure 2 and Figure 3 The connecting rod 1 421 is a telescopic structure; the connecting rod 2 422 includes an outer rod 4221, an inner rod 4222 and a preload spring 4223; the outer rod 4221 is connected to the clamping ring plate 43; the inner rod 4222 is slidably installed in the outer rod 4221; the preload spring 4223 is connected between the outer rod 4221 and the inner rod 4222.

When the three groups of clamping ring plates 43 are all subjected to pre-tightening force, the clamping ring plates 43 will generate an elastic clamping force on the water-cooled roller, thereby absorbing rotational resonance and ensuring the stability of the water-cooled roller during cutting. In addition, the pre-tightening force balance of the three connecting rods 422 can ensure that the axis of the clamping ring plate 43 will not deviate after the telescopic component 41 drives the clamping ring plate 43 to extend, thereby ensuring its overall stability.

[0046] As a specific embodiment of the present invention, refer to Figure 2 and Figure 3The clamping ring plate 43 includes a sliding end 431, a guide vane 432 and a clamping end 433; the sliding end 431 is slidably installed on the sliding rod seat 411; the guide vane 432 is connected to the sliding end 431; the clamping end 433 is connected to the guide vane 432, and the contact surface between the clamping end 433 and the workpiece is made of silicone rubber. During the cutting process, the clamping ring plate 43 will rotate along with the water-cooled roller and the three-jaw chuck 2. At this time, the guide vane 432 will accelerate the air flow rate on the surface of the water-cooled roller, so that the water-cooled roller can quickly dissipate heat during the cutting process, thereby reducing the processing error caused by thermal deformation. The thickness of the guide vane 432 needs to be thickened so that it will not bend when the clamping force is maximum, ensuring that the guide vane 432 is rigid enough. During the cutting process, as the clamping force increases, the guide vane 432 can keep the clamping end 433 pressed against the water-cooled roller, and the guide vane 432 is designed as an axial flow structure blade, so that the guide vane 432 can quickly diffuse the heat generated at one cutting end through the axial flow direction when rotating, and cooperate with the spraying of cutting fluid on the cutting end to accelerate the flow of cutting fluid and achieve the purpose of rapid heat exchange; the contact surface of the clamping end 433 is made of silicone rubber material, which can better adapt to water-cooled rollers of different diameters and ensure that it fully fits their surface, thereby cooperating with the rigid contact of the three-jaw chuck 2 to provide stable clamping force.

The pressure chamber 51 is disposed on the lathe body 1. The rotating chamber 52 is rotationally connected to the pressure chamber 51 and is connected to the three-jaw chuck 2. The adjustment piston 53 is connected to the pressure chamber 51 and has an axial groove 531 formed therein. The adjustment spring 54 is connected between the adjustment piston 53 and the pressure chamber 51. When the tool carrier 3 is feeding, the cutting force exerted on the water-cooled roller increases. During this process, the tool carrier 3 drives the adjustment piston 53 to slide via the feed assembly 7. The adjustment piston 53 compresses the water in the pressure chamber 51 and presses it toward the rotating chamber 52. The pressure exerted by the drive assembly 6 in the rotating chamber 52 causes the adjustment member 23 to rotate in the direction of the clamping jaws 22. At this time, the clamping jaws 22 and the multi-point clamping mechanism 4 increase the clamping force on the water-cooled roller to cope with the increased cutting force.

[0049] As a specific embodiment of the present invention, refer to Figure 4 、 Figure 7 and Figure 6 The feed assembly 7 includes a transverse groove 71, an axial connecting rod 72, a locking screw hole 73 and a locking bolt 74; the transverse groove 71 is provided on the tool carrier 3; one end of the axial connecting rod 72 is slidably installed in the transverse groove 71, and the other end is slidably installed in the axial groove 531, and one end of the axial connecting rod 72 is provided with a connecting screw hole 721; the locking screw hole 73 is provided on the tool carrier 3; the locking bolt 74 is installed on the locking screw hole 73, and when cutting, the locking bolt 74 is simultaneously installed in the locking screw hole 73 and the connecting screw hole 721. Before feeding, the tool carrier 3 is allowed to adjust its position freely, and the adjusting piston 53 will not slide during this process. When the tool carrier 3 is adjusted to the required position, since the locking screw hole 73 and the connecting screw hole 721 are always on the same axis, it is only necessary to tighten the locking bolt 74 and screw the locking bolt 74 into the locking screw hole 73 and the connecting screw hole 721 at the same time to ensure that the tool carrier 3 will drive the adjusting piston 53 to move in the feeding direction when feeding.

When the adjusting member 23 is rotated, it will drive the claw 22 to move radially, helping the claw 22 to clamp the water-cooled roller. When feeding, the adjusting piston 53 will slide in the pressure chamber 51, pressing the water in the pressure chamber 51 into the rotating chamber 52, thereby generating pressure on the ring plug 61. The pressure on the ring plug 61 will compress the pressure spring 62. At this time, the driving rack 63 will slide in the rack groove 521. When it slides to contact with the driving gear 64, it will squeeze the driving gear 64, so that the driving gear 64 drives the adjusting member 23 to rotate, and the rotation direction of the adjusting member 23 is the driving card The claw 22 moves radially in the direction of clamping the water-cooled roller, thereby increasing the clamping force of the claw 22 and the multi-point clamping mechanism 4 on the water-cooled roller, ensuring that the water-cooled roller remains stable during the cutting process, and in this process, the feed distance can be proportionally reduced by driving the rack 63 and the driving gear 64 and the transmission of the adjustment member 23, so that the radial clamping distance between the claw 22 and the clamping ring plate 43 is controlled within a range that will not cause damage to the water-cooled roller, and the water in the pressure chamber 51 can be replaced with gas, which can be more easily compressed under pressure, so that the clamping force can be elastically controlled to avoid damage to the water-cooled roller.

[0051] Working process: Place the water-cooled roller between the three claws 22 of the three-jaw chuck 2, adjust the telescopic length of the telescopic component 41 according to the length of the water-cooled roller, extend the telescopic component 41 to evenly distribute the clamping ring plate 43 on the water-cooled roller, rotate the adjusting part 23 to make the claw 22 clamp the water-cooled roller, and when the claw 22 moves radially, it will drive the multi-point clamping mechanism 4 to move radially, so that the clamping ring plate 43 clamps the water-cooled roller, adjust the tool carrier 3 to the initial position, and lock the feed component 7 and the tool carrier 3. When the tool carrier 3 drives the tool to cut and feed, the pressure adjustment component 5 will drive the adjustment part 23 to rotate further, thereby increasing the clamping force of the claw 22 and the clamping ring plate 43 on the water-cooled roller.

[0052] Specifically, the water-cooled roller is placed between the three claws 22 of the three-jaw chuck 2. According to the length of the water-cooled roller to be processed, the pneumatic push rod 412 is started. At this time, the pneumatic push rod 412 will push the clamping ring plate 43 farthest from the three-jaw chuck 2. When the pneumatic push rod 412 is extended or retracted, it will drive multiple clamping ring plates 43 to slide through the scissor rod group 413, so that multiple clamping ring plates 43 are evenly distributed on the outer wall of the water-cooled roller. At this time, the clamping claws 22 are driven to clamp the water-cooled roller by rotating the adjusting member 23. The roller end can slide radially with the clamping claw 22 through the sliding rod seat 411, thereby driving the clamping ring plate 43 to adjust the clamping force and realize multi-point clamping. Compared with the traditional three-jaw chuck 2, multi-point clamping can reduce the generation of single-point stress concentration and reduce the cantilever effect caused by excessive aspect ratio. It can also adapt to water-cooled rollers of different lengths through the sliding effect, ensure that the water-cooled roller is subjected to uniform clamping force, and prevent it from bending and deforming under rotation resonance and cutting force, which may lead to a decrease in processing accuracy.

[0053] After the water-cooled roller is fixed, the tool carrier 3 is adjusted to the initial cutting position, and then the locking bolt 74 is screwed into the locking screw hole 73 and the connecting screw hole 721 at the same time. At this time, the tool carrier 3 will drive the adjusting piston 53 to move in the feeding direction when feeding; when cutting starts, the three-jaw chuck 2 rotates and drives the multi-point clamping mechanism 4 to rotate synchronously. When the clamping ring plate 43 rotates, the guide vane 432 will accelerate the flow rate of the air on the surface of the water-cooled roller, so that the temperature generated by the cutting can be quickly dissipated; in the process of the tool carrier 3 driving the tool to feed, the movement of the tool carrier 3 will drive the adjusting piston 53 to slide through the axial connecting rod 72, and the adjusting piston 53 will press The water (or air) filled in the cavity 51 is compressed and pressed toward the rotating cavity 52. ​​The ring plug 61 in the rotating cavity 52 is compressed and will compress the pressure spring 62. At this time, the driving rack 63 will slide in the rack groove 521. When it slides to contact with the driving gear 64, it will squeeze the driving gear 64, so that the driving gear 64 drives the adjusting member 23 to rotate. The adjusting member 23 rotates and drives the claw 22 to move radially in the direction of clamping the water-cooled roller. During the movement of the claw 22, the telescopic assembly 41 and the clamping ring plate 43 will be driven to move synchronously, thereby increasing the clamping force of the claw 22 and the multi-point clamping mechanism 4 on the water-cooled roller, ensuring that the water-cooled roller remains stable during the cutting process.
