Description

Technical Field

[0001] The invention relates to the technical field of steel rim processing equipment, in particular to an automatic cutting and grinding equipment for a forklift steel rim. Background Art

[0002] In the field of industrial production, especially in the machinery manufacturing industry, precise cutting and grinding processes are essential to ensure product quality and production efficiency. Traditional steel ring processing equipment usually faces a series of technical challenges, especially in terms of automation and processing efficiency. These deficiencies are mainly manifested in the inability to achieve uniform processing of the outer and inner walls of the steel ring, and the need to frequently stop the machine to replace the cutter head or reassemble the steel ring when processing different parts, resulting in low production efficiency and increased processing costs.

[0003] In traditional forklift steel ring processing technology, the steel ring is usually fixed in the equipment by a single positioning chuck. Although this fixing method is simple, it has many inconveniences in actual operation. Since the positioning chuck can only clamp one end of the steel ring, the part of the steel ring close to the chuck cannot be touched by the processing equipment, so it cannot be cut or polished. This results in the entire steel ring cannot be fully processed in one clamping, and the machine needs to be stopped and the clamping posture of the steel ring needs to be readjusted so that the other side can also be processed accordingly. This operation not only increases production time, but also greatly reduces work efficiency and increases the complexity of the operation process, affecting the continuity and automation level of the production line.

[0004] Existing steel ring processing equipment mostly relies on manual operation or semi-automatic control system, which not only increases the labor intensity of operators, but also affects the processing accuracy and repeatability. In these equipment, the lack of automation limits the expansion of production efficiency and scale.

[0005] Due to design and technical limitations, traditional equipment can only process the inner wall or outer wall of the steel ring separately. For application scenarios where the inner and outer walls need to be processed on the same equipment, this design has to rely on frequent shutdowns and tool head changes, which in turn affects production continuity and efficiency.

[0006] During the processing, in order to effectively process the different processing surfaces of the steel ring, the operator must stop the machine and reassemble the steel ring. This process is not only time-consuming, but also increases the complexity of production and the probability of error. In addition, each stop and reassembly may introduce additional mechanical wear and challenges to equipment stability. Summary of the invention

[0007] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an automatic cutting and grinding equipment for forklift steel rims, which improves the automation level and production efficiency of steel rim processing, while ensuring the accuracy and stability of the processing process, and effectively solves the problems of traditional equipment in terms of operation complexity, production efficiency and processing quality.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0046] See also Figure 1-9 , and combined with the following embodiments, the technical solutions of the components involved in the present invention and the principles of coordinated operation between the components are described in detail.

[0047] Example 1

[0048] An automatic cutting and grinding device for a forklift steel rim comprises a machine platform 1 on which an assembly frame 11 is fixedly mounted.

[0049] It also includes a bidirectional feeding component 2, a driving component 3, and a positioning chuck 4 arranged on the top of the assembly frame 11. The bidirectional feeding component 2 is fixedly installed on the top of the assembly frame 11, and the bidirectional feeding component 2 includes two groups of assembly slides 21 that maintain symmetrical movement. Each group of assembly slides 21 is equipped with a positioning chuck 4 and a driving component 3 that is dynamically connected to the positioning chuck 4.

[0050] It also includes a dual-axis moving module 5 arranged on the machine table 1, and the dual-axis moving module 5 can be operated in a horizontal two-dimensional rectangular coordinate system; it also includes a reversing component 6, a lifting component 7, a tool head positioning seat 8, and a drilling component 9 which are assembled on the dual-axis moving module 5 and run synchronously with the dual-axis moving module 5, the reversing component 6 is assembled on the movable part of the dual-axis moving module 5, the lifting component 7 is assembled on the movable part of the reversing component 6, and the tool head positioning seat 8 and the drilling component 9 are assembled on the movable part of the lifting component 7.

[0051] The machine 1 and the assembly frame 11 fixed thereon can ensure that the various functional components involved in the equipment are stably assembled thereon. The positioning chuck 4 can effectively clamp and position the outer edge of one side of the forklift steel ring, and drive the two groups of assembly slides 21 and the two groups of positioning chucks 4 assembled on each assembly slide 21 to achieve movement close to or away from each other through the two-way feeding component 2. When the two groups of positioning chucks 4 are close to each other, the forklift steel ring can be fixed from the originally fixed positioning chuck 4 to another empty positioning chuck 4, realizing the transposition of the fixed direction of the forklift steel ring. In conjunction with the dual-axis travel module 5 and the various functional components assembled thereon, a series of finishing operations such as efficient drilling, cutting, and grinding can be performed on the outer wall, inner wall, and port positions on both sides of the forklift steel ring.

[0052] After the forklift steel ring clamping posture is changed under the coordinated operation of the two-way feeding component 2 and the positioning chuck 4, the two sets of assembly slides 21 and the positioning chucks 4 thereon are controlled to move away from each other to ensure the stable operation of the dual-axis travel module 5 and the various functional components assembled thereon without spatial motion interference with the two-way feeding component 2 and the positioning chuck 4.

[0053] The double-axis moving module 5 is arranged at the bottom of the two-way feeding assembly 2, and can move in the axial direction parallel to the positioning chuck 4 and the forklift steel ring and in the axial direction perpendicular to the positioning chuck 4 and the forklift steel ring. When the two-way feeding assembly 2 and the positioning chuck 4 change and adjust the clamping posture of the forklift steel ring, the double-axis moving module 5 drives the components assembled thereon to move as a whole in the axial direction perpendicular to the positioning chuck 4, so as to make way for the two sets of positioning chucks 4 moving in opposite directions to avoid spatial motion interference between each other.

[0054] The tool head positioning seat 8 can fix and assemble different types of cutting tool heads and grinding tool heads, and cooperate with the tool magazine (not shown in the accompanying drawings) assembled on one side of the machine 1 and the positioning piece (not shown in the accompanying drawings) assembled on one side of the grinding tool head to realize automatic replacement and precise positioning of various types of tool heads to meet the processing requirements of forklift steel rims.

[0055] The positioning part is driven by the cylinder to retract and retract. When replacing the cutter head, the positioning part is driven by the cylinder to retract to cancel the positioning effect on the existing cutter head. After cooperating with the tool magazine to complete the cutter head replacement operation, the cylinder drives the positioning part to extend to effectively position the reassembled cutter head.

[0056] The dual-axis travel module 5 cooperates with the lifting assembly 7 to drive the tool head positioning seat 8 and the drilling assembly 9 to move in a three-dimensional rectangular coordinate system, so that the drilling assembly 9 and the cutting head or grinding head fixedly assembled in the tool head positioning seat 8 can accurately process various parts of the forklift steel rim.

[0057] When cutting and grinding the forklift steel rim with the help of the tool head positioning seat 8 and the various types of cutting tools and grinding tools mounted thereon, the tool head is driven by the dual-axis travel module 5 and the lifting assembly 7 to the outer wall or inner wall position of the forklift steel rim. When the driving assembly 3 drives the positioning chuck 4 and the forklift steel rim thereon to run, the outer wall and inner wall of the forklift steel rim are effectively processed by the cutting or grinding tool head.

[0058] When drilling is performed on the inner side of the steel ring with the help of the drilling assembly 9, the control drive assembly 3 is in a shutdown and locked state. At this time, the corresponding positioning chuck 4 and the forklift steel ring thereon are also in a locked state. The dual-axis travel module 5 and the lifting assembly 7 cooperate to drive the drilling assembly 9 to run in a three-dimensional rectangular coordinate system to evenly drill holes in the forklift steel ring.

[0059] The reversing assembly 6 can drive the cutter head positioning seat 8 and the drilling assembly 9 to change positions, so as to effectively process the forklift steel rings assembled on different positioning chucks 4, and also facilitate the replacement operation of various types of cutter heads.

[0060] Example 2

[0061] In order to ensure the environmental stability of forklift steel rim processing operations and prevent the debris generated during cutting, grinding and drilling from splashing outward and affecting the personal safety of surrounding workers, the following technical solutions are provided.

[0062] The machine platform 1 and the assembly frame 11 are provided with a protective cover 12 on their peripheries, a telescopic protective door 121 is provided on the front side of the protective cover 12, and a numerical control computer, operation buttons 122 and a display screen 123 connected to the numerical control computer signals are also provided on the outside of the protective cover 12.

[0063] The setting of the protective cover 12 can effectively separate the forklift steel ring processing environment from the external environment, ensure that the forklift steel ring processing process is not disturbed by the external environment, and prevent the debris generated during the forklift steel ring processing from splashing outward. The telescopic protective door 121 can automatically control its opening and closing posture. During the loading and unloading process of the forklift steel ring, the telescopic protective door 121 is controlled to be in an open state to facilitate the loading and unloading operation of the forklift steel ring at the telescopic protective door 121. During the forklift steel ring process, the telescopic steel ring is closed to realize the protective function of the protective cover 12.

[0064] The CNC computer is connected to the control unit signal of the tool magazine with the bidirectional feeding component 2, the driving component 3, the positioning chuck 4, the dual-axis travel module 5, the reversing component 6, the lifting component 7, the drilling component 9 and the cylinder for controlling the extension and retraction of the positioning part on the tool head positioning seat 8 to realize the automatic operation of the control components.

[0065] In addition, it is also connected with the signals of various assembled detection units to receive detection data and execute control commands based on this. The detection unit at least includes a position sensor for detecting whether the forklift steel ring is assembled in place on the positioning chuck 4, and a position sensor for detecting whether the tool head is assembled in place on the tool head positioning seat 8. It also includes sensors for the operating postures of the bidirectional feeding component 2, the biaxial travel module 5, the lifting component 7, and the reversing component 6.

[0066] Example 3

[0067] In order to ensure that the bidirectional feeding assembly 2 can be stably installed on the assembly frame 11 and that the bidirectional feeding assembly 2 can drive the two groups of assembly slides 21 to achieve a relative or opposite operating state, the following technical solution is provided.

[0068] The bidirectional feeding component 2 also includes an assembly top seat 22, a driving motor A23, and an adjusting screw A24. The assembly top seat 22 is fixedly installed on the assembly frame 11, and two groups of assembly slide grooves 221 arranged in the same straight line direction are opened at the bottom of the assembly top seat 22. The assembly slides 21 are slidably installed in the two groups of assembly slide grooves 221. The adjusting screw A24 is rotatably installed in the two groups of assembly slide grooves 221, and the adjusting screw A24 is provided with two sections of thread grooves arranged in opposite directions of the thread spiral. The two groups of assembly slides 21 are respectively screwed to the two sections of thread grooves on the adjusting screw A24. The driving motor A23 is fixedly installed on the assembly top seat 22 and maintains a power connection with the adjusting screw.

[0069] The assembly top seat 22 can be stably installed on the top of the assembly frame 11 to ensure that the drive motor A23, the adjusting screw A24, and the assembly slide 21 can be stably assembled thereon. Since the two sets of screw threads on the adjusting screw A24 are arranged in opposite directions, when the drive motor A23 drives the adjusting screw A24 to operate, the two sets of assembly slides 21 can be driven simultaneously to maintain constant speed and reverse operation, thereby realizing the operation of the two sets of assembly slides 21 and the assembly positioning chucks 4 thereon approaching or moving away from each other.

[0070] In order to ensure that the positioning chuck 4 can be stably assembled on the assembly slide 21 and to ensure that the positioning chuck 4 can effectively fix one end of the forklift steel ring, the following technical solution is provided.

[0071] The two sets of positioning chucks 4 are arranged symmetrically. The positioning chuck 4 includes a claw 41, a telescopic cylinder A42, and a rotating base 43, an assembly inner disk 44, an assembly outer disk 45, and a driving disk 46 that are arranged coaxially. The rotating base 43 is rotatably mounted on the assembly slide 21, the assembly inner disk 44 is fixedly mounted on the rotating base 43, the assembly outer disk 45 is fixedly mounted on the assembly inner disk 44, and the driving disk 46 is rotatably mounted in the assembly outer disk 45. The driving disk 46 is fixedly connected with an eccentric pin shaft 461 arranged in the assembly inner disk 44. The telescopic cylinder A42 is arranged in the assembly inner disk 44, and the two ends of the telescopic cylinder A42 are respectively hinged with the assembly inner disk 44 and the eccentric pin shaft 461. The assembly outer disk 45 is provided with multiple groups of guide grooves 451 distributed along its own diameter direction, and each group of guide grooves 451 is slidably installed with a claw 41, and the claw 41 is fixed with a driving slide column 411 arranged in the assembly outer disk 45. The driving disk 46 is provided with multiple groups of arc guide grooves 462, and the arc guide grooves 462 maintain a sliding combination with the corresponding driving slide column 411.

[0072] The assembly base can ensure that the positioning chuck 4 is stably installed on the assembly slide 21, and ensure that the assembly inner disk 44 and the assembly outer disk 45 are stably installed. The setting of the assembly inner disk 44 can ensure that the telescopic cylinder A42 is stably installed therein. The setting of the assembly outer disk 45 can ensure that the claw 41 and the drive disk 46 are stably installed thereon and therein. The inner edge structure of the claw 41 is arranged to fit the outer edge of the forklift steel ring port, which can ensure that the claw 41 effectively clamps and fixes the outer edge of the forklift steel ring port.

[0073] Studs are fixed on the assembly base and the assembly inner disk 44. The assembly inner disk 44 and the assembly outer disk 45 are assembled and combined by screwing and fixing with studs and nuts, which is convenient for quick disassembly and assembly, so as to facilitate disassembly and maintenance of the internal telescopic cylinder A42 and the drive disk 46.

[0074] The telescopic cylinder A42 includes two groups symmetrically distributed along the axis, which telescope together to drive the driving disk 46 to operate stably, and then drive the driving slides on each group of claws 41 to run synchronously through the arc guide groove 462 on the driving disk 46, thereby realizing the synchronous retraction and extension of each group of claws 41, so as to achieve effective clamping and fixation of the forklift steel ring.

[0075] In some of the implementations, in order to ensure that the drive assembly 3 can be stably installed on the assembly slide 21 and that the drive assembly 3 can drive the positioning chuck 4 to operate stably, the following technical solutions are provided.

[0076] An installation groove 211 is provided on the assembly slide 21, and the driving component 3 includes a driving motor B31 and a driving bevel gear A32. The driving motor B31 is fixedly installed in the installation groove 211, and the driving bevel gear A32 is fixedly connected to the output shaft of the driving motor B31. A transmission bevel gear A431 is fixedly connected to the rotating base 43, and the transmission bevel gear A431 is meshed with the driving bevel gear A32.

[0077] The setting of the mounting groove 211 can ensure that the drive motor B31 is stably installed on the assembly slide 21. The drive motor B31 adopts a conical rotor motor. When the motor is stopped, its output shaft is in a locked state, thereby ensuring that the rotating base 43 connected to its power is also in a locked state, ensuring that the positioning chuck 4 and the forklift steel ring clamped thereon are also locked.

[0078] When the driving motor B31 works to drive the driving bevel gear A32 to operate, it can drive the transmission bevel gear A431 and the rotating base 43 to operate stably, and then drive the positioning chuck 4 and the clamped forklift steel ring to operate stably.

[0086] Example 5

[0087] In order to ensure that the reversing assembly 6 can be stably assembled on the dual-axis traveling module 5, the dual-axis traveling module 5 drives it to achieve lateral and longitudinal position adjustment to ensure that the reversing assembly 6 can achieve stable reversing adjustment, and the following technical solutions are provided.

[0088] The reversing assembly 6 includes an assembly support 61, an assembly bracket 62, a drive motor E63, and a worm wheel 64 and a worm 65 that maintain a matching combination. The assembly support 61 is fixedly mounted on the transverse slide 58, the assembly bracket 62 is rotatably mounted on the assembly support 61, the drive motor E63 is fixedly mounted on the assembly support 61 and maintains a power connection with the worm 65, and the worm wheel 64 is fixedly connected to the bottom of the assembly bracket 62.

[0089] The arrangement of the assembly support 61 can ensure that the reversing assembly 6 is stably installed on the dual-axis traveling module 5 , and the dual-axis traveling module 5 drives the reversing assembly 6 to achieve synchronous position adjustment.

[0090] When the driving motor E63 drives the worm 65 to operate, it can drive the worm wheel 64 and the assembly bracket 62 fixed to the worm wheel 64 to operate stably. The combination of the worm wheel 64 and the worm 65 also has the effect of speed reduction, torque increase and self-locking. When the worm 65 transmits power to the worm wheel 64, the rotation speed is reduced, and then the assembly bracket 62 can be driven stably to operate, thereby driving the lifting assembly 7, the tool head positioning seat 8, and the drilling assembly 9 to operate stably to realize the annular function. The power of the worm 65 can only be transmitted to the inner worm wheel 64 in one direction. After the reversing angle adjustment is completed and the driving motor E63 is stopped, the power at the worm wheel 64 end cannot be transmitted to the worm 65, that is, the worm 65 locks the worm wheel 64, ensuring that the lifting assembly 7, the tool head positioning seat 8, and the drilling assembly 9 assembled thereon always maintain a specific flip angle for operation.

[0091] In order to ensure that the lifting assembly 7 can be stably assembled on the reversing assembly 6, so that the lifting assembly 7 can effectively adjust the height position of the tool head positioning seat 8 and the drilling assembly 9, the following technical solution is provided.

[0092] The lifting assembly 7 includes a lifting bracket 71, an adjusting screw B72, and a driving motor F73. The lifting bracket 71 is slidably installed on the assembly bracket 62 and moves up and down in the vertical direction. The tool head positioning seat 8 and the drilling assembly 9 are assembled on the lifting bracket 71. The adjusting screw B72 is rotatably installed on the assembly bracket 62 and arranged in the vertical direction. The adjusting screw B72 is rotationally connected to the lifting bracket 71. The driving motor F73 is fixedly installed at the bottom of the assembly bracket 62, and a driving bevel gear B731 is fixedly connected to the output shaft of the driving motor F73. A transmission bevel gear B721 that meshes with the driving bevel gear B731 is fixedly connected to the adjusting screw B72.

[0093] When the driving motor F73 is running and drives the driving bevel gear B731 to rotate, it can drive the transmission bevel gear B721 and the adjusting screw B72 to operate, and then drive the lifting bracket 71 and the tool head positioning seat 8 and drilling assembly 9 assembled thereon to rise and fall synchronously, thereby realizing the height adjustment of the tool head positioning seat 8 and the drilling assembly 9.

[0094] In some implementations, in order to ensure that the drilling assembly 9 can be stably installed on the lifting assembly 7, and to ensure that the drilling assembly 9 can accurately drill holes on the inner side of the forklift steel ring, so as to ensure that the forklift steel ring can be stably assembled on the forklift half-axle, the following technical solutions are provided.

[0095] The drilling assembly 9 includes an axle box assembly 91, a tool holder 92, and a drill bit 93. The axle box assembly 91 is fixedly installed on the top of the lifting bracket 71, the tool holder 92 is rotatably installed on the axle box assembly 91 and is power-connected to the driving unit in the axle box assembly 91, and the drill bit 93 is fixedly installed on the tool holder 92.

[0096] The axle box assembly 91 can drive the tool holder 92 and the drill bit 93 fixed on the tool holder 92 to operate stably, and then cooperate with the lifting assembly 7, the dual-axis travel module 5 and the driving assembly 3 used to drive the positioning chuck 4 to operate, so as to realize precise drilling of the processing points on the inner side of the forklift steel ring. After the drilling is completed, the drill bit 93 is driven out by the dual-axis travel module 5. After the driving assembly 3 drives the positioning chuck 4 and the forklift steel ring fixed thereon to operate at a specific angle, the drilling assembly 9 performs the drilling operation of the next assembly hole.
