Description

Technical Field

[0001] This invention belongs to the field of roller sleeve technology, and particularly relates to a high-efficiency grooving equipment for processing roller sleeve mounting grooves. Background Technology

[0002] As a key and vulnerable component of core equipment in industries such as metallurgy, mining, building materials, and power (e.g., roller presses, rolling mills, crushers, and conveyor rollers), the roller sleeve is mainly fitted onto the outside of the roller mandrel. Its core functions include bearing materials, resisting wear, and protecting the roller mandrel, directly determining the overall operational stability, service life, and production efficiency of the equipment. The roller sleeve achieves positioning, locking, and transmission cooperation with the roller mandrel through mounting grooves on its inner wall.

[0003] Currently, the industry generally uses traditional general-purpose processing equipment or simple tooling for grooving the roller sleeve mounting groove. This method cannot balance processing efficiency, accuracy, applicability, and economy, making the processing of the roller sleeve mounting groove a bottleneck that restricts the mass production of roller sleeves and the assembly quality of the whole machine. Therefore, developing a high-efficiency grooving equipment specifically for processing the roller sleeve mounting groove to make up for the shortcomings of existing processing technology has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] To address the above problems, this invention provides a high-efficiency grooving device for machining roller sleeve mounting grooves.

[0005] This invention is implemented as follows: A high-efficiency grooving device for processing roller sleeve mounting grooves includes a worktable. A first base is horizontally fixed on one side of the upper end of the worktable. A first hydraulic cylinder is horizontally fixed on the upper end of the first base to ensure the stability of the first hydraulic cylinder's position. A second base is fixedly fixed at the middle position of the other side of the upper end of the worktable. A bearing seat is vertically fixed on the upper end of the second base to ensure the stability of the bearing seat's position. One end of the piston rod of the first hydraulic cylinder tightly passes through the center of the bearing inside the bearing seat, ensuring that the piston rod of the first hydraulic cylinder is in a horizontal state when extended. A detachable cutting mechanism is provided at the middle position of the lower end of the piston rod of the first hydraulic cylinder, which is both reliable in connection and easy to replace as needed. The grooving of the roller sleeve mounting groove is performed by the cutting mechanism. The upper ends of the worktable between the first base and the second base are symmetrical. A base plate is provided, the lower end of which is connected to the upper end of the worktable via a slot. This ensures a reliable connection between the base plate and the worktable, preventing the base plate from detaching, and also allows the base plate to move horizontally along the worktable. A second hydraulic cylinder is vertically and symmetrically fixed on both sides of the upper end of the base plate. A support block is horizontally fixed on the upper end of each second hydraulic cylinder. The support block moves smoothly up and down under the action of the second hydraulic cylinder. A V-shaped groove is formed in the middle of the upper end of each support block, which clamps and supports the roller sleeve, ensuring its stable position. Support columns are vertically and symmetrically fixed on the upper ends of the support blocks on both sides of the V-shaped groove. A first screw is vertically fixed on the upper end of each support column. A pressure plate is horizontally fitted onto the corresponding first screw, and a locking nut is tightly fitted onto the first screw. The pressure plate presses against the upper end of the roller sleeve, and the locking nut is tightened, thus ensuring the stability of the roller sleeve's position.

[0006] Preferably, a rectangular slot is formed at the middle of the lower end of the piston rod of the first hydraulic cylinder, and grooves are symmetrically formed on the lower sidewalls of the piston rod on both sides of the slot. A cutting head is provided at the lower end of the piston rod of the first hydraulic cylinder to perform grooving on the roller sleeve mounting groove. An insert is fixedly provided at the upper end of the cutting head. The position of the insert corresponds to the slot and the size is matched. The insert is tightly inserted into the slot to prevent the position of the insert from moving in the slot. A first through hole is formed on the wall of the piston rod of the first hydraulic cylinder between the slot and the groove. A second through hole is horizontally formed on the insert. The second through hole corresponds to the position of the first through hole and the same diameter. A bolt is horizontally arranged through the first through hole and the second through hole. A nut is tightly fitted on the bolt to ensure a firm and reliable connection between the insert and the piston rod of the first hydraulic cylinder and to facilitate disassembly and assembly. The cutting head can be replaced as needed. The nut and bolt are located in the groove to prevent the nut and bolt from contacting the inner wall of the roller sleeve.

[0007] Preferably, bottom blocks are symmetrically fixed on both sides of the lower end of the base plate, and a T-shaped groove is opened in the middle of the lower end of the bottom block. T-shaped rails are symmetrically fixed on both sides of the upper end of the worktable. The rails are set in the grooves to ensure a reliable connection between the bottom blocks and the rails, and to allow the bottom blocks to move along the rails.

[0008] Preferably, a block is fixedly mounted on the outer wall of the base block. The block has a threaded hole and a third through hole horizontally opened. A bidirectional threaded rod and a limiting rod are horizontally arranged side by side on one side of the worktable. A motor and an end block are fixedly mounted on the outer wall of the worktable at both ends of the bidirectional threaded rod. One end of the bidirectional threaded rod is tightly threaded through the threaded hole on the block and rotatably connected to the end block. The other end of the bidirectional threaded rod is connected to the drive shaft of the motor through a reducer to ensure the stability of the position of the bidirectional threaded rod. The reducer reduces the speed of the bidirectional threaded rod, and the motor drives the bidirectional threaded rod to rotate slowly, thereby moving the two blocks closer or further apart. The distance between the two support blocks is then adjusted according to the length of the roller sleeve. Limiting blocks are fixedly mounted on the outer wall of the worktable at both ends of the limiting rod. The limiting rod tightly passes through the third through hole on the block, and both ends of the limiting rod are fixedly connected to the limiting blocks to ensure the stability of the position of the limiting rod, thereby ensuring the smooth movement of the blocks.

[0009] Preferably, a sleeve is fixedly provided on the outer edge of the end of the first hydraulic cylinder, and a support plate is vertically and symmetrically fixed on one end of the sleeve near the bearing seat and on both sides of the piston rod of the first hydraulic cylinder to support the end of the roller sleeve and ensure the stability of the position of one end of the roller sleeve.

[0010] Preferably, a horizontal bar is fixedly installed at the middle position of the outer wall of the sleeve. A laser marking device is installed at the end of the horizontal bar facing the piston rod of the first hydraulic cylinder. The light emitted by the laser marking device is at the same horizontal plane as the center of the piston rod of the first hydraulic cylinder. The center position of the piston rod of the first hydraulic cylinder is marked by the laser marking device, so that the height of the support block is adjusted by the second hydraulic cylinder, so that the center of the roller sleeve and the center of the piston rod of the first hydraulic cylinder are at the same horizontal plane, thereby facilitating the piston rod of the first hydraulic cylinder to pass smoothly through the center of the roller sleeve.

[0011] Preferably, a controller is provided on one side of the workbench. The controller is electrically connected to the first hydraulic cylinder, the second hydraulic cylinder, the motor and the laser marking instrument. The controller can reasonably control the working process of the first hydraulic cylinder, the second hydraulic cylinder, the motor and the laser marking instrument.

[0012] Preferably, a second screw is horizontally fixed on the support column of the base plate on the side opposite to the first base. The second screw faces the bearing seat and passes through a vertical baffle. A locking nut is tightly fitted on the second screw. Tightening the locking nut ensures the stability of the baffle position. The baffle blocks the other end of the roller sleeve, thereby ensuring the stability of the roller sleeve position. An arc-shaped first pressure groove is opened at the middle of the lower end of the baffle. The first pressure groove is in close contact with the piston rod of the first hydraulic cylinder to ensure the stability of the piston rod position of the first hydraulic cylinder.

[0013] Preferably, an arc-shaped second pressure groove is provided at the middle position of the lower end of the pressure plate. The second pressure groove is in close contact with the outer wall of the roller sleeve, which increases the contact surface between the pressure plate and the roller sleeve and further ensures the stability of the roller sleeve position.

[0014] Preferably, a metal anti-slip pad is fixedly provided on the inner wall of the support block located at the V-shaped groove. The upper end of the anti-slip pad is provided with staggered teeth to increase the friction between the inner wall of the support block and the roller sleeve and prevent the roller sleeve from shifting position.

[0015] The beneficial effects of this invention are as follows: The motor drives the bidirectional threaded rod to rotate slowly, thereby bringing the two blocks closer or further apart. The distance between the two support blocks is then adjusted according to the length of the roller sleeve. The roller sleeve is clamped and supported by the V-shaped groove at the upper end of the support block, ensuring the stability of the roller sleeve position. The support block moves smoothly up and down under the action of the second hydraulic cylinder, adjusting the height of the roller sleeve. A detachable cutting mechanism is provided at the middle position of the lower end of the piston rod of the first hydraulic cylinder, which is both reliable and easy to replace as needed. When the piston rod of the first hydraulic cylinder reciprocates, the cutting mechanism performs grooving processing on the roller sleeve mounting groove, which is highly accurate, efficient, easy to operate, economical, practical, safe and reliable.

[0018] like Figure 1-6The diagram illustrates a high-efficiency grooving device for machining roller sleeve mounting grooves, comprising a worktable 1. A first base 2 is horizontally fixed on one side of the upper end of the worktable 1, and a first hydraulic cylinder 3 is horizontally fixed on the upper end of the first base 2 to ensure the stability of the position of the first hydraulic cylinder 3. A second base 4 is fixedly fixed at the middle position of the other side of the upper end of the worktable 1, and a bearing seat 5 is vertically fixed on the upper end of the second base 4 to ensure the stability of the position of the bearing seat 5. One end of the piston rod 6 of the first hydraulic cylinder 3 tightly passes through the center of the bearing inside the bearing seat 5, ensuring that the piston rod 6 of the first hydraulic cylinder 3 is in a horizontal state when extended. A detachable cutting mechanism is provided at the middle position of the lower end of the piston rod 6 of the first hydraulic cylinder 3, which is both reliable and easy to replace as needed. The cutting mechanism is used to groove the mounting groove of the roller sleeve 45. A base plate 7 is symmetrically arranged on the upper end of the worktable 1 between the first base 2 and the second base 4. The lower end of the base plate 7 is connected to the worktable 45. The upper end of the platform 1 is connected by a slot, which ensures a reliable connection between the base plate 7 and the worktable 1, preventing the base plate 7 from detaching from the worktable 1, and also allows the base plate 7 to move horizontally along the worktable 1. The upper ends of the base plate 7 are vertically and symmetrically fixed with second hydraulic cylinders 8. The upper ends of the second hydraulic cylinders 8 are horizontally fixed with support blocks 9. The support blocks 9 move smoothly up and down under the action of the second hydraulic cylinders 8. The middle of the upper end of the support block 9 is provided with a V-shaped clamping groove 10, which clamps and supports the roller sleeve 45 to ensure the stability of the position of the roller sleeve 45. The upper ends of the support blocks 9 on both sides of the V-shaped clamping groove 10 are vertically and symmetrically fixed with support columns 11. The upper ends of the support columns 11 are vertically fixed with first screws 12. The corresponding first screws 12 are horizontally fitted with pressure plates 13. Locking nuts 14 are tightly fitted on the first screws 12. The pressure plates 13 press on the upper end of the roller sleeve 45. Tightening the locking nuts 14 ensures the stability of the position of the roller sleeve 45.

[0019] A rectangular slot 15 is formed at the middle of the lower end of the piston rod 6 of the first hydraulic cylinder 3. Grooves 16 are symmetrically formed on the lower sidewalls of the piston rod 6 on both sides of the slot 15. A cutting head 17 is provided at the lower end of the piston rod 6 of the first hydraulic cylinder 3. The cutting head 17 is used to groove the mounting groove of the roller sleeve 45. An insert block 18 is fixedly provided at the upper end of the cutting head 17. The insert block 18 corresponds to the slot 15 in position and size, and is tightly inserted into the slot 15 to prevent movement of the insert block 18 within the slot 15. The first groove 16 between the slot 15 and the groove 16... A first through hole 19 is provided on the piston rod wall 6 of the hydraulic cylinder 3, and a second through hole 20 is provided horizontally on the insert block 18. The second through hole 20 is positioned corresponding to the first through hole 19 and has the same diameter. A bolt 21 is horizontally arranged through the first through hole 19 and the second through hole 20. A nut 22 is tightly fitted on the bolt 21, which not only ensures a firm and reliable connection between the insert block 18 and the piston rod 6 of the first hydraulic cylinder 3, but also facilitates disassembly and assembly, allowing the cutting head 17 to be replaced as needed. The nut 22 and the bolt 21 are both located in the groove 16 to prevent the nut 22 and the bolt 21 from contacting the inner wall of the roller sleeve 45.

[0020] The bottom plate 7 has symmetrically fixed bottom blocks 23 on both sides of its lower end. A T-shaped groove 24 is provided in the middle of the lower end of the bottom block 23. The worktable 1 has symmetrically fixed T-shaped rails 25 on both sides of its upper end. The rails 25 are set in the grooves 24, which not only ensures the reliable connection between the bottom block 23 and the rails 25, but also allows the bottom block 23 to move along the rails 25.

[0021] A block 26 is fixedly mounted on the outer wall of the base block 23. A threaded hole 27 and a third through hole 28 are horizontally opened on the block 26. A bidirectional threaded rod 29 and a limiting rod 30 are horizontally arranged side-by-side on one side of the workbench 1. A motor 31 and an end block 32 are fixedly mounted on the outer wall of the workbench 1 at both ends of the bidirectional threaded rod 29. One end of the bidirectional threaded rod 29 is tightly threaded through the threaded hole 27 on the block 26 and rotatably connected to the end block 32. The other end of the bidirectional threaded rod 29 is connected to the drive shaft of the motor 31 via a reducer 33, ensuring the bidirectional threaded rod 29... To ensure the stability of position 9, the reducer 33 reduces the speed of the bidirectional threaded rod 29, and the motor 31 drives the bidirectional threaded rod 29 to rotate slowly, thereby moving the two blocks 26 closer or further apart. The distance between the two support blocks 9 is then adjusted according to the length of the roller sleeve 45. Limiting blocks 34 are fixedly installed on the outer wall of the worktable 1 located at both ends of the limiting rod 30. The limiting rod 30 passes tightly through the third through hole 28 on the block 26, and both ends of the limiting rod 30 are fixedly connected to the limiting blocks 34 to ensure the stability of the position of the limiting rod 30, thereby ensuring the smooth movement of the block 26.

[0022] A sleeve 35 is fixedly provided on the outer edge of the end of the first hydraulic cylinder 3. A support plate 36 is vertically and symmetrically fixed on one end of the sleeve 35 near the bearing seat 5 and on both sides of the piston rod 6 of the first hydraulic cylinder 3 to support the end of the roller sleeve 45 and ensure the stability of the position of one end of the roller sleeve 45.

[0023] A horizontal bar 37 is fixedly installed at the middle position of the outer wall of the sleeve 35. A laser marking device 38 is installed at the end of the horizontal bar 37 and facing the piston rod 6 of the first hydraulic cylinder 3. The light emitted by the laser marking device 38 is at the same horizontal plane as the center of the piston rod 6 of the first hydraulic cylinder 3. The center position of the piston rod 6 of the first hydraulic cylinder 3 is marked by the laser marking device 38, so that the height of the support block 9 is adjusted by the second hydraulic cylinder 8, so that the center of the roller sleeve 45 is at the same horizontal plane as the center of the piston rod 6 of the first hydraulic cylinder 3, thereby facilitating the smooth passage of the piston rod 6 of the first hydraulic cylinder 3 through the center of the roller sleeve 45.

[0024] A controller 39 is provided on one side of the workbench 1. The controller 39 is electrically connected to the first hydraulic cylinder 3, the second hydraulic cylinder 8, the motor 31 and the laser marking instrument 38. The controller 39 can reasonably control the working process of the first hydraulic cylinder 3, the second hydraulic cylinder 8, the motor 31 and the laser marking instrument 38.

[0025] A second screw 40 is horizontally fixed on the support column 11 of the base plate 7 on the side opposite to the first base 2. The second screw 40 faces the bearing seat 5. The second screw 40 passes through the vertical baffle 41 and a locking nut 14 is tightly fitted on the second screw. Tightening the locking nut 14 ensures the stability of the position of the baffle 41. The baffle 41 blocks the other end of the roller sleeve 45, thereby ensuring the stability of the position of the roller sleeve 45. An arc-shaped first pressure groove 42 is opened at the middle of the lower end of the baffle 41. The first pressure groove 42 is in close contact with the piston rod 6 of the first hydraulic cylinder 3, ensuring the stability of the position of the piston rod 6 of the first hydraulic cylinder 3.

[0026] An arc-shaped second pressure groove 43 is provided at the middle position of the lower end of the pressure plate 13. The second pressure groove 43 is in close contact with the outer wall of the roller sleeve 45, increasing the contact surface between the pressure plate 13 and the roller sleeve 45, and further ensuring the stability of the position of the roller sleeve 44.

[0027] A metal anti-slip pad 44 is fixedly installed on the inner wall of the support block 9 located at the V-shaped groove 10. The upper end of the anti-slip pad 44 is provided with staggered teeth to increase the friction between the inner wall of the support block 9 and the roller sleeve 45 and prevent the roller sleeve 45 from shifting position.

[0028] During operation, the piston rod 6 of the first hydraulic cylinder 3 is in the retracted state, and the roller sleeve 45 is inserted into the clamping grooves 10 on the two support blocks 9. The locking nut 14 is tightened, so that the pressure plate 13 is tightly pressed against the roller sleeve 45. According to the light emitted by the laser marking instrument 38, the controller 39 synchronously controls the second hydraulic cylinder 8 to adjust the height of the support block 9, so that the center of the roller sleeve 45 is at the same level as the center of the piston rod 6 of the first hydraulic cylinder 3. The controller 39 controls the piston rod 6 of the first hydraulic cylinder 3 to smoothly pass through the center of the roller sleeve 45. One end of the roller sleeve 45 abuts against the support plate 36, and the other end of the roller sleeve 45 abuts against the baffle 41. The slot 15 at the lower end of the piston rod 6 is located on one side of the roller sleeve 45. The insert block 18 at the upper end of the cutting head 17 is placed in the slot 15. The controller 39 controls the piston rod 6 of the first hydraulic cylinder 3 to reciprocate. The cutting head 17 cuts the inner wall of the roller sleeve 45. As the processing progresses, the specifications of the cutting head 17 are changed to gradually increase the cutting depth, thereby completing the grooving of the mounting groove of the roller sleeve 45.
