Description

Technical Field

[0001] This invention relates to the field of elevator roller processing technology, specifically to a processing device for the inner and outer rings of elevator rollers. Background Technology

[0002] Elevator rollers are key load-bearing components of elevator operating systems. They are generally composed of a metal core and an outer polyurethane coating. The outer circle of the core must fit tightly with the polyurethane coating. The rope groove has an arc cross-section to accommodate and guide the steel wire rope. The dimensional accuracy of the outer diameter and the cross-sectional shape accuracy of the R-groove directly affect the fit of the steel wire rope and the smoothness of elevator operation. Therefore, the precision machining of the roller's outer diameter and R-groove is the core process in elevator roller manufacturing.

[0003] Existing equipment requires different equipment to process the outer diameter and R-groove of elevator rollers. The processing mode of processing the outer diameter and R-groove separately by equipment and in separate processes has the following problems: First, the workpiece needs to be disassembled and reassembled multiple times when it is transferred between different equipment. The positioning error introduced by each reclamping directly leads to the coaxiality deviation between the cylindrical surface of the outer diameter and the arc surface of the R-groove, and the loss of accuracy is difficult to avoid. Therefore, a special equipment is needed that can complete the processing of the outer diameter and R-groove of elevator rollers on one machine at the same time. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an elevator roller inner and outer ring processing device to address the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an elevator roller inner and outer ring machining device, comprising a frame, a mounting platform, a roller clamp for holding the elevator roller on the top of the mounting platform, a cutting tool fixing platform on one side of the mounting platform located on the roller clamp, and a first cutting tool assembly for machining the outer diameter of the elevator roller and a second cutting tool assembly for machining the R-groove of the elevator roller respectively located on both sides of the roller clamp, the cutting tool fixing platform being capable of reciprocating about the roller clamp in the mounting direction of the first cutting tool assembly and the second cutting tool assembly.

[0006] Using the above technical solution, the first and second cutting tool assemblies are integrated on the same cutting tool fixing table. After the roller is clamped once, the cutting tool fixing table can reciprocate to complete the outer diameter machining and R-groove machining in sequence. There is no need to transfer the workpiece between different equipment and repeatedly clamp it, which avoids the positioning error caused by multiple clamping. The coaxiality accuracy between the outer diameter and the R-groove is guaranteed. At the same time, one machine can complete two processes, reducing the number of machines and the process flow time.

[0007] The aforementioned elevator roller inner and outer ring machining device can be further configured as follows: the first cutting tool assembly includes a cutting tool fixing table fixedly installed on one side of the roller fixture, a first cutting tool table with first mounting slots for mounting outer diameter cutting tools on both sides, and a plurality of detachable first mounting shafts at the top of the first mounting slots of the first cutting tool table to enable detachable connection of the outer diameter cutting tool to the first mounting slots, and the first mounting shafts passing through the first cutting tool table and the outer diameter cutting tool.

[0008] The above technical solution is adopted. The first tool holder is provided with mounting slots on both sides, and the outer diameter turning tools can be installed on both sides simultaneously or separately according to the machining needs. When the tool holder moves back and forth, the turning tools on both sides can participate in cutting alternately. The first mounting shaft is fixed in a way that makes the positioning of the outer diameter turning tool in the mounting slot more stable. When disassembling, the tool can be replaced by pulling out the mounting shaft. Daily maintenance and tool replacement are convenient.

[0009] The aforementioned elevator roller inner and outer ring machining device can be further configured as follows: the second cutting tool assembly includes a cutting tool fixing table located on the side of the roller fixture away from the first cutting tool table, and a second cutting tool table is provided on both sides of the second cutting tool table for mounting the R-groove cutting tool. The second cutting tool table is provided with a plurality of second mounting shafts at the top of the second mounting grooves. The second mounting shafts pass through the second cutting tool table and the R-groove cutting tool to enable the R-groove cutting tool to be detachably connected to the second mounting grooves. The second cutting tool table is provided with an anti-chip structure at the top of the R-groove cutting tool.

[0010] Using the above technical solution, mounting slots are provided on both sides of the second tool holder, allowing the installation of R-groove cutting tools according to machining needs. The through-mounting method of the second mounting shaft ensures stable positioning of the R-groove cutting tool within the mounting slot, facilitating disassembly and replacement. The anti-chip structure at the top of the R-groove cutting tool blocks chips during cutting. In actual use, the outer diameter cutting tool of the first tool assembly uses a downward-sloping cutting head. When the fixture rotates towards the outer diameter cutting tool, the cutting waste falls directly downwards due to gravity, eliminating the need for an additional chip-blocking device. However, the R-groove cutting tool of the second tool assembly uses an upward-sloping arc-shaped cutting head. During R-groove machining, chips fly upwards due to cutting force. Therefore, an anti-chip structure is installed at the top of the R-groove cutting tool to block and intercept the upward-flying chips.

[0011] The aforementioned elevator roller inner and outer ring machining device can be further configured such that: the anti-chip structure includes a mounting bracket that is vertically fixed on the side of the R-groove cutting tool of the second cutting tool holder, the height of the mounting bracket is higher than the height of the roller fixture, and an anti-chip plate is horizontally provided at the end of the mounting bracket.

[0012] Using the above technical solution, the mounting bracket is vertically fixed to one side of the second tool holder, and its height is higher than that of the roller clamp, so that the anti-chip plate at the end covers the area above the R-groove tool in the horizontal direction. The upward flying chips generated by the R-groove tool during the cutting process are intercepted by the anti-chip plate. After the chips hit the anti-chip plate, they fall down, reducing the range of chips flying out of the machining area. At the same time, the mounting bracket moves together with the tool holder, and the anti-chip plate always stays above the R-groove tool during the reciprocating feed of the tool holder.

[0013] The aforementioned elevator roller inner and outer ring processing device can be further configured such that: the cutting tool fixing table has a plurality of third mounting grooves along the installation direction of the first cutting tool table and the second cutting tool table, and the bottom of the first mounting groove and the second mounting groove has a plurality of fixing holes, and the fixing holes are fixedly connected to the third mounting grooves through fixing shafts.

[0014] Using the above technical solution, the third mounting slot is arranged along the length of the tool holder. The first and second tool holders are positioned and fixed in the third mounting slot by cooperating with the fixed shaft through the fixing holes at the bottom. The fixed shaft passes between the fixing hole and the third mounting slot, so that the mounting position of the tool holder on the tool holder can be adjusted along the direction of the third mounting slot. When machining rollers of different specifications, the relative distance between the two tool assemblies and the roller fixture can be changed by adjusting the fixed position of the first and second tool holders on the third mounting slot. The machining requirements of workpieces of different sizes can be adapted without changing the tool holder.

[0015] The aforementioned elevator roller inner and outer ring processing device can be further configured as follows: the roller fixture includes a fixture machine table disposed on the top of the mounting platform, the fixture machine table is provided with a first drive component, the fixture machine table is provided with a fixed expansion shaft for fixing the elevator roller on the side facing the first tool table and the second tool table, the first drive component can drive the fixed expansion shaft to rotate, the fixed expansion shaft includes a rotating shaft disposed inside the fixture machine table and expansion claws evenly distributed at the end of the rotating shaft, the rotating shaft is connected to the first drive component, and the expansion claws are inserted through the center opening of the elevator roller and tightened and fixed.

[0016] Using the above technical solution, the expansion claws penetrate from the center of the roller and then expand outwards, positioning and clamping the roller from the inner hole. Compared with the external clamping method, this avoids the machining areas of the outer diameter and R-groove, ensuring that the first and second cutting tool assemblies are not interfered with by the fixture during machining. The expansion claws are evenly distributed along the end of the rotating shaft, applying tension force to the inner hole of the roller from multiple directions simultaneously, keeping the roller centered during rotational machining. The rotating shaft is driven to rotate by the first drive assembly, and the roller rotates together with the fixed expansion shaft. The cutting of the outer diameter and R-groove can be completed by the reciprocating feed of the cutting tool fixed table.

[0017] The aforementioned elevator roller inner and outer ring processing device can be further configured as follows: the first drive assembly includes a motor mounting bracket mounted on the mounting platform, the motor mounting bracket is horizontally mounted with a first drive motor, the output end of the first drive motor is fixedly connected to the rotating shaft, and the motor mounting bracket is provided with a rotating shaft cover for protection and cooling on the outer periphery of the rotating shaft.

[0018] Using the above technical solution, the first drive motor is fixed on the mounting platform by the motor mounting bracket, and its output end is directly connected to the rotating shaft, reducing intermediate transmission links and making power transmission more direct. The rotating shaft cover is fitted around the outer circumference of the rotating shaft, which wraps and isolates the rotating shaft during operation, reducing the possibility of external debris coming into contact with the rotating shaft. At the same time, the cover structure is conducive to heat dissipation of the rotating shaft through surface airflow when rotating at high speed, thus playing a cooling role for the rotating shaft.

[0019] The aforementioned elevator roller inner and outer ring processing device can be further configured as follows: the mounting platform is provided with a movable platform at the tool fixing platform; the movable platform is provided with a first transmission screw along the extension direction of the tool fixing platform; a second drive motor connected to the first transmission screw is provided on one side of the movable platform; a plurality of first movable sliders are provided at the bottom of the tool fixing platform; the surface of the movable platform is provided with an embedded groove for the first movable slide rail to be embedded in; the tool fixing platform is slidably connected to the first movable sliders through the first movable slide rail; the first transmission screw is provided with a first movable block; the first movable block is fixedly connected to the bottom of the tool fixing platform, so that the first transmission screw can drive the tool fixing platform to reciprocate about the roller clamp in the installation direction of the first tool assembly and the second tool assembly.

[0020] Using the above technical solution, the second drive motor drives the first transmission screw to rotate, the first moving block moves along the screw axis and drives the tool fixing table to move together, and the first moving slider at the bottom of the tool fixing table is embedded in the inner groove on the surface of the moving table. During the movement, the moving direction of the tool fixing table is guided and limited, so that the tool fixing table moves back and forth in a straight line, ensuring the stability of the movement trajectory of the first tool assembly and the second tool assembly during the feeding process and reducing the deviation during the machining process.

[0021] The aforementioned elevator roller inner and outer ring processing device can be further configured as follows: the mounting platform extends towards the expansion claw direction and is provided with a second moving slide rail; the center of the second moving slide rail is provided with a second transmission screw; the mounting platform is located at the end of the second moving slide rail and is provided with a third drive motor; the second transmission screw is fixedly connected to the bottom of the moving platform by providing a second moving block; and the third drive motor can drive the moving platform to reciprocate towards the expansion claw direction.

[0022] Using the above technical solution, the third drive motor drives the second transmission screw to rotate, the second moving block moves along the screw axis and drives the entire moving table to move along the direction of the second moving slide rail, so that the moving table can feed or retract in the direction of the expanding claw. The bottom of the moving table is fixedly connected to the second moving block. During the movement, the second moving slide rail guides the movement direction of the moving table. Combined with the reciprocating movement of the cutting tool fixing table along the direction of the first transmission screw, the cutting tool fixing table has two mutually perpendicular degrees of freedom in the horizontal plane, so that the first cutting tool assembly and the second cutting tool assembly can be adjusted along the roller axis and radial direction respectively during the machining process to adapt to the machining requirements of rollers of different specifications.

[0023] The aforementioned elevator roller inner and outer ring processing device can be further configured as follows: the mounting table is located at the bottom of the cutting tool fixing table and a scrap trough is provided; an inclined guide plate is provided on one side of the mounting table and extends toward the scrap trough; a scrap collection cavity is also provided inside the mounting table and the scrap collection cavity is connected to the scrap trough.

[0024] Using the above technical solution, the scrap trough at the bottom of the tool holder receives the chips that fall during the machining process. The inclined guide plate extends from one side of the mounting table toward the scrap trough, guiding the chips scattered on the surface of the mounting table into the scrap trough. The scrap collection chamber is connected to the scrap trough, and the chips that enter the scrap trough are further collected into the scrap collection chamber for easy subsequent centralized cleaning.

[0025] The beneficial effects of the present invention are as follows: by integrating the first tool assembly and the second tool assembly on the same tool fixing table, the roller can complete the outer diameter and R-groove machining in sequence after one clamping, without the need for transfer between different equipment and repeated clamping, thus ensuring coaxiality accuracy, while reducing the number of equipment and process flow time.

Detailed Implementation

[0027] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0028] Example: Figure 1-5 The elevator roller inner and outer ring machining device shown includes a frame 1, a mounting platform 2, and a roller clamp 3 for holding the elevator roller on the top of the mounting platform 2. A cutting tool fixing table 4 is located on one side of the roller clamp 3 on the mounting platform 2. The cutting tool fixing table 4 is located on both sides of the roller clamp 3 and has a first cutting tool assembly 5 for machining the outer diameter surface 43 of the elevator roller and a second cutting tool assembly 6 for machining the R-groove 44 of the elevator roller. The cutting tool fixing table 4 can reciprocate about the roller clamp 3 in the mounting direction of the first cutting tool assembly 5 and the second cutting tool assembly 6. The first cutting tool assembly 5 and the second cutting tool assembly 6 are integrated on the same cutting tool fixing table 4, so that after the roller is clamped once, the cutting tool fixing table 4 can reciprocate to complete the outer diameter machining and R-groove machining in sequence. There is no need to transfer the workpiece between different equipment and repeatedly clamp it, avoiding the positioning error caused by multiple clamping. The coaxiality accuracy between the outer diameter and the R-groove is guaranteed. At the same time, one machine can complete two processes, reducing the number of machines and the process flow time.

[0029] The roller clamp 3 includes a clamping machine base 21 mounted on the top of the mounting platform 2. A first drive assembly 22 is installed inside the clamping machine base 21. A fixed expansion shaft 23 for fixing the elevator roller is located on the side of the clamping machine base 21 facing the first tool holder 7 and the second tool holder 11. The first drive assembly 22 can drive the fixed expansion shaft 23 to rotate. The fixed expansion shaft 23 includes a rotating shaft 24 disposed inside the clamping machine base 21 and expansion claws 25 evenly distributed at the end of the rotating shaft 24. The rotating shaft 24 is connected to the first drive assembly 22. The expansion claws 25 pass through the center opening of the elevator roller and are tightened and fixed. During machining, the expansion claws 25 penetrate from the center opening of the roller and tighten outwards, positioning and clamping the roller from the inner hole. Compared to external clamping, this avoids the machining areas of the outer diameter and R-groove, ensuring that the first tool assembly 5 and the second tool assembly 6 are not interfered with by the clamp during machining. The expansion claws 25 are evenly distributed along the end of the rotating shaft 24, simultaneously applying tension force to the inner hole of the roller from multiple directions, ensuring that the roller rotates during machining. During the process, the rotating shaft 24 is driven to rotate by the first drive assembly 22, and the roller rotates together with the fixed expansion shaft 23. The cutting of the outer diameter and R groove can be completed by the reciprocating feed of the tool fixing table 4. The first drive assembly 22 includes a motor mounting bracket 26 set on the mounting table 2. The motor mounting bracket 26 is horizontally set with a first drive motor 27. The output end of the first drive motor 27 is fixedly connected to the rotating shaft 24. The motor mounting bracket 26 is provided with a rotating shaft cover 28 on the outer periphery of the rotating shaft 24 for protection and cooling. The output end of the first drive motor 27 is directly connected to the rotating shaft 24, reducing intermediate transmission links and making power transmission more direct. The rotating shaft cover 28 is sleeved on the outer periphery of the rotating shaft 24, which wraps and isolates the rotating shaft 24 during operation, reducing the possibility of external debris coming into contact with the rotating shaft 24. At the same time, the cover structure is conducive to the cooling of the rotating shaft 24 by surface airflow when rotating at high speed.

[0030] The tool holder 4 has several third mounting slots 18 along the mounting direction of the first tool holder 7 and the second tool holder 11. The bottom of the first tool holder 7 and the second tool holder 11 has several fixing holes 19. The fixing holes 19 are fixedly connected to the third mounting slots 18 through fixing shafts 20. The third mounting slots 18 are arranged along the length of the tool holder 4. The first tool holder 7 and the second tool holder 11 are positioned and fixed in the third mounting slots 18 by cooperating with the fixing shafts 20 through the fixing holes 19 at the bottom. The fixing shafts 20 pass between the fixing holes 19 and the third mounting slots 18, so that the mounting position of the tool holders on the tool holder 4 can be adjusted along the direction of the third mounting slots 18. When machining rollers of different specifications, the relative distance between the two tool assemblies and the roller fixture 3 can be changed by adjusting the fixed position of the first tool holder 7 and the second tool holder 11 on the third mounting slots 18. The tool holders can be adapted to the machining requirements of workpieces of different sizes without changing the tool holders.

[0031] The first tool assembly 5 includes a tool holder 4 fixedly mounted on one side of the roller clamp 3, and a first tool holder 7. Both sides of the first tool holder 7 have first mounting slots 8 for mounting outer diameter cutting tools 9. The first tool holder 7 has several detachable first mounting shafts 10 at the top of the first mounting slots 8. The first mounting shafts 10 pass through the first tool holder 7 and the outer diameter cutting tool 9, allowing the outer diameter cutting tool 9 to be detachably connected to the first mounting slots 8. Since both sides of the first tool holder 7 have first mounting slots 8, outer diameter cutting tools 9 can be mounted simultaneously or separately on both sides according to machining needs. When the tool holder 4 reciprocates, the outer diameter cutting tools 9 on both sides can alternately participate in cutting. The fixed mounting method of the first mounting shafts 10 makes the positioning of the outer diameter cutting tool 9 within the first mounting slots 8 relatively stable. During disassembly, the first mounting shafts 10 can be pulled out to replace the outer diameter cutting tool 9, making daily maintenance and tool replacement convenient.

[0032] The second tool assembly 6 includes a tool holder 4 located on the side of the roller clamp 3 away from the first tool holder 7, and a second tool holder 11. Both sides of the second tool holder 11 have second mounting slots 12 for mounting R-groove tools 13. The second tool holder 11 has several second mounting shafts 14 at the top of the second mounting slots 12. The second mounting shafts 14 pass through the second tool holder 11 and the R-groove tools 13, allowing the R-groove tools 13 to be detachably connected to the second mounting slots 12. The second tool holder 11 is located at the top of the R-groove tools 13. The device features a chip-prevention structure 15. The second tool holder 11 has second mounting slots 12 on both sides, allowing for the installation of R-groove cutting tools 13 as needed. The through-mounting method of the second mounting shaft 14 ensures stable positioning of the R-groove cutting tool 13 within the second mounting slots 12, facilitating easy disassembly and replacement. In actual use, the outer diameter cutting tool 9 of the first tool assembly 5 uses a downward-sloping cutting tip. When the roller clamp 3 rotates towards the outer diameter cutting tool 9, the cutting waste falls directly downwards due to gravity, eliminating the need for an additional chip-blocking device. Meanwhile, the second tool assembly... The R-groove turning tool 13 of part 6 adopts an upward-sloping arc-shaped tool head. When machining the R-groove 44, the chips are scattered upward under the action of cutting force. Therefore, an anti-chip flying structure 15 is set on the top of the R-groove turning tool 13 to block and intercept the upward-scattering chips. The anti-chip flying structure 15 includes a mounting bracket 16 that is vertically fixed on one side of the R-groove turning tool 13 and located on the second tool holder 11. The height of the mounting bracket 16 is higher than the height of the roller clamp 3. An anti-chip flying plate 17 is horizontally set at the end of the mounting bracket 16. The mounting bracket 16 is vertically fixed to the second tool holder. On one side of 11, its height is higher than that of the roller clamp 3, so that the anti-chip plate 17 at the end covers the area above the R-groove cutting tool 13 in the horizontal direction. The upward flying chips generated by the R-groove cutting tool 13 during the cutting process are intercepted by the anti-chip plate 17. After the chips hit the anti-chip plate 17, they fall down, reducing the range of chips flying out of the machining area. At the same time, the mounting bracket 16 moves together with the cutting tool fixing table 4. During the reciprocating feed of the cutting tool fixing table 4, the anti-chip plate 17 always stays above the R-groove cutting tool 13, continuously playing the role of chip blocking.

[0033] Mounting platform 2 is located at tool fixing platform 4 and has a movable platform 29. The movable platform 29 has a first transmission screw 30 extending along the tool fixing platform 4. A second drive motor 31 connected to the first transmission screw 30 is located on one side of the movable platform 29. The bottom of the tool fixing platform 4 has several first movable sliders 32. The surface of the movable platform 29 has an inset groove 33 for the first movable slide rail 34 to be embedded. The tool fixing platform 4 is slidably connected to the first movable sliders 32 via the first movable slide rail 34. The first transmission screw 30 has a first movable block 35, which is fixedly connected to the bottom of the tool fixing platform 4, enabling the first transmission screw 30 to drive the tool fixing platform 4. The tool fixing table 4 reciprocates around the roller clamp 3 in the mounting direction of the first cutting tool assembly 5 and the second cutting tool assembly 6. During operation, the second drive motor 31 drives the first transmission screw 30 to rotate, and the first moving block 35 moves along the screw axis and drives the tool fixing table 4 to move together. The first moving slider 32 at the bottom of the tool fixing table 4 is embedded in the groove 33 on the surface of the moving table 29. During the movement, it guides and limits the movement direction of the tool fixing table 4, so that the tool fixing table 4 moves back and forth in a straight line, ensuring the stability of the movement trajectory of the first cutting tool assembly 5 and the second cutting tool assembly 6 during the feeding process and reducing the deviation during the machining process.

[0034] The mounting platform 2 extends towards the expansion claw 25 and is provided with a second movable slide rail 36. A second transmission screw 37 is located at the center of the second movable slide rail 36. A third drive motor 38 is located at the end of the second movable slide rail 36 on the mounting platform 2. The second transmission screw 37 is fixedly connected to the bottom of the moving platform 29 via a second movable block 39. The third drive motor 38 can drive the moving platform 29 to reciprocate towards the expansion claw 25. The third drive motor 38 drives the second transmission screw 37 to rotate, and the second movable block 39 moves along the screw axis, thus driving the entire moving platform 29 to move along the second movable slide rail 37. The slide rail 36 moves in the direction of the moving table 29, allowing it to feed or retract towards the direction of the expanding claw 25. The bottom of the moving table 29 is fixedly connected to the second moving block 39. During the movement, the second moving slide rail 36 guides the movement direction of the moving table 29. Combined with the reciprocating movement of the tool fixing table 4 along the direction of the first transmission screw 30, the tool fixing table 4 has two mutually perpendicular degrees of freedom of movement in the horizontal plane, allowing the first tool assembly 5 and the second tool assembly 6 to be adjusted along the axial and radial directions of the roller respectively during the machining process, adapting to the machining requirements of rollers of different specifications.

[0035] The mounting table 2 is located at the bottom of the tool holder 4 and has a scrap trough 40. An inclined guide plate 41 is provided on one side of the mounting table 2, extending towards the scrap trough 40. The mounting table 2 also has a scrap collection chamber 42, which is connected to the scrap trough 40. The scrap trough 40 at the bottom of the tool holder 4 collects the chips that fall during the machining process. The inclined guide plate 41 extends at an angle from one side of the mounting table 2 towards the scrap trough 40, guiding the chips scattered on the surface of the mounting table 2 into the scrap trough 40. The scrap collection chamber 42 is connected to the scrap trough 40, and the chips that enter the scrap trough 40 are further collected into the scrap collection chamber 42 for easy subsequent centralized cleaning.

[0036] Working principle: The elevator roller is fitted onto the expansion claw 25 of the fixed expansion shaft 23 through its center opening. The expansion claw 25 expands outward to position and clamp the roller from the inner hole. The first drive motor 27 drives the fixed expansion shaft 23 and the roller to rotate together through the rotating shaft 24. The second drive motor 31 drives the first transmission screw 30 to rotate, which drives the cutting tool fixing table 4 to reciprocate along the first moving slide rail 34 through the first moving block 35. The third drive motor 38 drives the second transmission screw 37 to rotate, which drives the moving table 29 to feed or retract along the second moving slide rail 36 through the second moving block 39. This allows the first cutting tool assembly 5 and the second cutting tool assembly 6 to adjust their positions along the axial and radial directions of the roller, respectively. When machining the outer diameter, the cutting tool fixing table 4 moves towards the first cutting tool assembly 5. The outer diameter cutting tool 9 on the first tool holder 7 cuts the outer diameter surface 43 of the roller. The chips fall downward under the action of gravity and are guided into the scrap groove 40 by the inclined guide plate 41, and finally collect in the scrap collection chamber 42. When machining the R groove, the tool fixing table 4 moves towards the direction of the second tool assembly 6. The R groove cutting tool 13 on the second tool holder 11 cuts the R groove 44 of the roller. The upward-sloping arc-shaped cutting head of the R groove cutting tool 13 causes the chips to fly upward. The anti-scraping chip plate 17 at the end intercepts the flying chips and makes them fall down, also entering the scrap groove 40 and the scrap collection chamber 42. The tool fixing table 4 moves back and forth on the moving table 29 along the direction of the first transmission screw 30, and completes the outer diameter machining and R groove machining in sequence. The roller completes all machining processes in one clamping.
