Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, in particular to laser cutting equipment. Background Art

[0002] In the field of mechanical manufacturing, laser cutting technology has become an important processing method. However, traditional laser cutting equipment has exposed a series of limitations when facing many practical processing needs.

[0003] In the mechanical manufacturing process, castings and forgings are extremely common. Due to the characteristics of their manufacturing process, these workpieces inevitably have uneven surfaces.

[0004] Traditional clamping devices usually adopt a relatively simple rigid clamping structure and lack the ability to adapt to the irregularities of the workpiece surface.

[0005] When clamping workpieces with uneven surfaces, it is impossible to fully conform to the contour of the workpiece, resulting in limited contact area and uneven distribution of clamping force.

[0006] This not only makes it difficult to achieve stable and reliable clamping, but also easily causes damage to the workpiece surface during the clamping process, affecting the quality of the workpiece and subsequent processing steps.

[0007] In addition, the traditional clamping device has poor adjustment flexibility. When facing workpieces of different sizes and shapes, it takes a lot of time to replace or adjust the clamp, which is cumbersome and inefficient.

[0008] For example, for some castings with complex shapes or large size variations, it may be necessary to customize a variety of fixtures of different specifications, which undoubtedly increases production costs and production cycles.

[0009] In view of this, this application is hereby filed. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-7 , the present invention provides a technical solution: A laser cutting device comprises a cutting table 1, a clamping plate 4 and a cutting head 6. The bottom surface of the cutting table 1 is provided with four columns, the bottom ends of the columns are provided with shock-absorbing pads, and the cutting head 6 is located on the top surface of the cutting table 1.

[0025] The cutting table 1 is supported by four columns so that the cutting table 1 is at a suitable working height for easy operation and material placement.

[0026] The shock-absorbing pad at the bottom of the column plays a key role in shock absorption. During the laser cutting process, the operating parts of the cutting equipment itself (such as the motor operation, the cutting head 6 moving mechanism, etc.) will vibrate, and the vibration in the external environment (such as the vibration generated by the operation of other nearby equipment, the vibration transmitted by the ground, etc.) may also affect the stability of the cutting table 1.

[0027] The shock-absorbing pad is usually made of rubber, a material with elastic and damping properties. When the vibration wave is transmitted to the shock-absorbing pad, its elastic deformation can absorb part of the vibration energy, while the damping property gradually dissipates the vibration energy, thereby reducing the impact of the vibration on the cutting table 1 and ensuring that the cutting table 1 is relatively stable during the cutting process.

[0028] A driving disk 2 is rotatably connected to the cutting table 1, a vertical groove 101 is formed through the top surface of the cutting table 1, an inclined groove 201 is formed on the top surface of the driving disk 2, the width of the inclined groove 201 is greater than that of the vertical groove 101, the vertical groove 101 is staggered with the inclined groove 201, a tilting block 3 is arranged in the inclined groove 201, a positioning column 301 is provided on the top surface of the tilting block 3, the other end of the positioning column 301 is fixedly connected to the adjusting groove 5, and there are four groups of vertical grooves 101, inclined grooves 201 and tilting blocks 3, which are arranged in a circular array with equal intervals.

[0029] When the driving disk 2 rotates around its axis, the special staggered layout formed by the inclined groove 201 and the vertical groove 101 and the structural feature of the inclined block 3 inside the inclined groove 201 work together to cause the inclined block 3 to produce a displacement with a clear direction under the precise guidance of the inclined groove 201 according to the specific inclination angle and geometric shape of the inclined groove 201.

[0030] Due to the inclined characteristics of the inclined groove 201, a mechanism for vector decomposition and conversion of the circular rotational motion of the driving disk 2 is constructed at the spatial geometric level, thereby successfully converting the rotational motion of the driving disk 2 into a linear motion mode of the tilting block 3 in the inclined direction.

[0031] The positioning column 301 fixedly arranged on the top of the tilting block 3 is tightly connected with the adjusting groove 5 to form a rigid transmission connection.

[0032] Therefore, when the tilting block 3 is displaced due to the rotation of the driving disk 2 , the rigidity transmission of the positioning column 301 will inevitably drive the adjusting slot 5 to synchronously perform corresponding movements.

[0033] Considering that the vertical grooves 101, the inclined grooves 201 and the inclined blocks 3 are arranged in four groups at equal intervals in the form of a circular array, the ingenious layout of the multiple groups of structures forms a symmetrical and balanced mechanical distribution pattern in space.

[0034] During the rotation of the driving disc 2, the four groups of structures work together according to their respective geometric positions and motion characteristics.

[0035] They respond synchronously to the rotation instructions of the driving disk 2 in the time and space dimensions, and through mutual mechanical coupling and motion coordination, effectively eliminate the unbalanced force and displacement deviation that may be caused by the movement of a single structure, so that the adjustment slot 5 and its components that are mechanically connected or functionally related to it can achieve relatively uniform, stable and precise motion trajectory and position adjustment, providing a reliable motion foundation and precise position guarantee for the realization of subsequent related process or equipment functions.

[0036] The above structural design can realize accurate position adjustment of components related to the adjustment slot 5.

[0037] For example, if the adjustment slot 5 is used to install a certain processing tool or positioning device, the position coordinates thereof in the plane can be precisely controlled by rotating the driving disk 2, thereby meeting some processing or assembly requirements with high position accuracy.

[0038] For example, in precision machinery manufacturing, when parts are positioned and assembled with high precision, this structure can accurately move the parts to the specified position, improving the assembly quality and performance consistency of the product.

[0039] Due to the inclined setting of the inclined groove 201, the inclined block 3 and the components connected thereto can achieve multi-directional (not just simple radial or circumferential) position changes when the drive disk 2 rotates. This multi-directional adjustment capability increases the flexibility and adaptability of the device.

[0040] For example, in some automated production lines, when workpieces of different shapes and sizes need to be processed or handled, the relevant processing devices or clamping devices can use this structure to easily adjust to the appropriate posture and position, so that they can process various types of workpieces, reduce equipment replacement and adjustment time, and improve production efficiency.

[0041] The space inside the cutting table 1 and the driving disc 2 is used to realize the adjustment function, so that the whole structure is relatively compact.

[0042] Compared with some external and complex adjustment mechanisms, the overall space occupied by the equipment is reduced. At the same time, the multiple groups of structures arranged at equal intervals in the circumferential array make the force more uniform during the adjustment process, thereby improving the stability of the structure during the adjustment process.

[0043] For example, in some small processing equipment or equipment with high space requirements, this compact and stable adjustment structure can better meet the design requirements and ensure that the equipment operates efficiently and stably in a limited space.

[0044] Furthermore, an adjustment groove 5 is provided on the top surface of the tilting block 3, an adjustment cavity 501 is opened in the adjustment groove 5, a plurality of limit protrusions 502 are provided in the adjustment cavity 501, an elastic pad 401 is provided on the front surface of the splint 4, a positioning block 402 is fixedly connected to the bottom surface of the splint 4, and the positioning block 402 is vertically slidably arranged in the adjustment cavity 501.

[0045] The elastic pad 401 allows the front side of the clamp plate 4 to be deformed to a certain extent, so as to stably clamp the irregular surface of the workpiece. The positioning block 402 can slide vertically, so that the position of the positioning block 402 in the limiting protrusion 502 can be adjusted by lifting the clamp plate 4, thereby achieving clamping of the irregularity.

[0046] When facing a workpiece with an irregular surface, since the elastic pad 401 has a deformable characteristic, when the clamping plate 4 applies a clamping force, the elastic pad 401 can be deformed accordingly according to the undulating shape of the workpiece surface.

[0047] This deformation enables the clamping surface of the clamping plate 4 to better fit the irregular contour of the workpiece, thereby increasing the contact area and friction between the clamping plate 4 and the workpiece.

[0048] At the same time, the positioning block 402 can slide vertically in the adjustment cavity 501 , and the position of the positioning block 402 can be adjusted between the limiting protrusions 502 in the adjustment cavity 501 by lifting or pressing the clamping plate 4 upward or downward.

[0049] For example, when there is a protrusion on the surface of the workpiece, the clamping plate 4 is lifted up to make the positioning block 402 slide upward, and the elastic pad 401 is further compressed and deformed to adapt to the protrusion, ensuring that the entire workpiece surface can obtain a stable clamping force; if the workpiece has a depression, the clamping plate 4 can be pressed down appropriately, and the deformation of the elastic pad 401 is also relied on to fill the depression, so that the clamping is uniform and reliable.

[0050] The reaction force generated during the deformation of the elastic pad 401 is transmitted to the positioning block 402 through the clamping plate 4 .

[0051] When the positioning block 402 slides in the adjustment cavity 501 , it is restricted by the limiting protrusions 502 , and these limiting protrusions 502 play a role of balancing and guiding force.

[0052] When the elastic pad 401 generates uneven deformation force due to the irregular surface of the workpiece, the limiting protrusion 502 ensures that the positioning block 402 will not be deflected or excessively displaced, so that the clamping plate 4 can stably transmit the clamping force in the vertical direction and maintain the relative position unchanged in the horizontal direction, thereby achieving stable clamping of irregular workpieces in multiple directions.

[0053] The design of combining the elastic pad 401 with the vertically slidable positioning block 402 greatly improves the clamping adaptability to irregular workpieces.

[0054] In industrial production, many workpieces do not have an ideal flat surface, such as castings, forgings, etc., which often have various uneven surfaces.

[0055] This clamping structure can effectively deal with these situations, reduce problems such as unstable clamping and processing errors caused by irregular workpiece shapes, improve the equipment's processing capabilities for complex-shaped workpieces, and broaden the equipment's application range.

[0056] For example, in the manufacturing of automotive parts, when some casting parts such as engine blocks are laser cut, the clamping device can adapt well to their surface irregularities and ensure a smooth cutting process.

[0057] Since irregular workpieces can be stably clamped, the workpiece can maintain a relatively fixed position and posture during the laser cutting process, reducing cutting deviations caused by loose or shaking clamping.

[0058] The cutting head 6 can accurately process the workpiece according to a predetermined cutting path, thereby improving the cutting accuracy, such as the straightness of the cutting seam, the dimensional accuracy, etc.

[0059] At the same time, stable clamping is also conducive to ensuring the quality of the cutting surface, reducing surface roughness and improving the overall quality of the product.

[0060] For example, in precision machining, for some parts with complex shapes and high precision requirements, this clamping method helps to achieve high-precision laser cutting and produce products that meet strict quality standards.

[0061] Compared with the traditional method of customizing special clamping tools or using complex adjustment means for irregular workpieces, the clamping plate 4 of this structure is easier to operate.

[0062] The operator only needs to adjust the position of the positioning block 402 by simply lifting or pressing down the clamp 4 to adapt to different irregular workpieces, greatly shortening the clamping time. In a production environment of batch production or frequent replacement of workpieces, it can significantly improve production efficiency and reduce labor costs.

[0063] For example, in a small machining workshop, when it is necessary to process irregular metal workpieces of various shapes, this convenient clamping method can quickly complete the clamping preparation of the workpiece and enable the equipment to enter the cutting processing state faster.

[0064] A chamfer 406 is formed on the positioning block 402 , and the chamfer 406 is formed toward the axis of the cutting table 1 .

[0065] The height of the chamfer 406 is flush with the height of the limiting protrusion 502. When the staff adjusts the splint 4 inward, they can directly push it, and the positioning block 402 will rise along the chamfer 406, and then when it enters the next limiting protrusion 502, it will drop into the limiting protrusion 502 due to gravity and be repositioned.

[0066] A connecting column 403 is fixedly connected to the bottom surface of the splint 4, and the other end of the connecting column 403 is fixedly connected to the positioning block 402. A movable plate 404 is slidably connected to the side wall of the connecting column 403. The movable plate 404 is located in the adjustment cavity 501, and a spring 405 is arranged between the positioning block 402 and the movable plate 404.

[0067] When the worker needs to adjust the clamping plate 4 inwards to adapt to workpieces of different sizes, the clamping plate 4 is directly pushed.

[0068] Since the chamfer 406 on the positioning block 402 facing the axis of the cutting table 1 is flush with the limiting protrusion 502 , the positioning block 402 will rise along the chamfer 406 during the pushing process.

[0069] At this time, the connecting post 403 moves with the positioning block 402, and the movable plate 404 slides relative to the connecting post 403 in the adjusting cavity 501, and the spring 405 is compressed.

[0070] After the positioning block 402 passes over the current set of limiting protrusions 502 , the positioning block 402 drops to between the next limiting protrusions 502 under the action of gravity, thereby realizing the rapid repositioning of the clamping plate 4 at different positions.

[0071] This structure utilizes the cooperation between the chamfer 406 and the limiting protrusion 502 to convert the lateral force of manual pushing into the vertical displacement of the positioning block 402, thereby realizing the rapid switching and precise positioning of the clamping plate 4.

[0072] In the whole process, the spring 405 plays the role of buffering and force balancing.

[0073] When the positioning block 402 rises, the spring 405 absorbs part of the energy to prevent the structure from being damaged by a large impact force caused by a sudden displacement change.

[0074] At the same time, when the positioning block 402 descends to between the limiting protrusions 502 , the spring 405 releases the stored energy, and the auxiliary positioning block 402 falls smoothly into the limiting protrusions 502 .

[0075] The design of the chamfer 406 of the positioning block 402 and the limiting protrusion 502 enables fast and easy position adjustment of the clamping plate 4 .

[0076] During the production and processing, it is often necessary to frequently adjust the spacing between the clamping plates 4 according to the different sizes of workpieces.

[0077] This structure does not require a complicated adjustment mechanism or precise manual measurement and positioning. The staff only needs to simply push the clamping plate 4 to quickly reposition the clamping plate 4, which greatly shortens the clamping preparation time and improves production efficiency.

[0078] For example, in a workshop that batch processes workpieces of various specifications, the use of this clamping plate 4 adjustment method can significantly reduce the clamping time of each workpiece, thereby improving the overall production output.

[0079] The structural design is relatively simple, and mainly relies on the ingenious cooperation between the chamfer 406 of the positioning block 402, the limiting protrusion 502, the connecting column 403, the movable plate 404 and the spring 405 to achieve the adjustment and clamping functions of the clamping plate 4.

[0080] This simplicity makes the structure cheaper to manufacture and maintain, and reduces possible points of failure that can occur due to structural complexity.

[0081] In a long-term industrial production environment, it can maintain high reliability and stability, reduce equipment downtime and maintenance time, and improve the overall operating efficiency of the equipment.

[0082] For example, in some continuous production lines that have high requirements on equipment stability, this simple and reliable clamping plate 4 structure can reduce production line interruptions caused by clamping device failures and ensure production continuity.

[0083] Furthermore, a worm gear 7 is rotatably connected to the bottom surface of the cutting table 1, a connecting port is opened through the bottom surface of the cutting table 1, the worm gear 7 is fixedly connected to the driving disk 2 through the connecting port, and a mounting plate 102 is provided on one side of the bottom surface of the cutting table 1, and a worm 701 meshing with the worm gear 7 is rotatably connected to the mounting plate 102.

[0084] A turning handle 702 is disposed at one end of the worm 701 close to the edge of the cutting table 1 . The turning handle 702 is L-shaped, and its rotation range does not overlap with the cutting table 1 .

[0085] By rotating the handle 702, since the handle 702 is connected to the worm 701 and is L-shaped, its rotation range does not overlap with the cutting table 1, which is convenient for the operator to apply force to operate.

[0086] The worm 701 rotates accordingly, because the worm 701 is meshed with the worm wheel 7 , and according to the transmission principle of the worm 701 , the rotational motion of the worm 701 will be converted into the rotation of the worm wheel 7 .

[0087] The worm gear 7 is fixedly connected to the driving disc 2 through a connection port on the bottom surface of the cutting table 1 , so the rotation of the worm gear 7 will drive the driving disc 2 to rotate synchronously.

[0088] The rotation of the driving disk 2 causes the tilting block 3 in the tilting slot 201 to be displaced, and finally the position of the adjustment slot 5 and the clamping plate 4 connected to the tilting block 3 are adjusted to meet the clamping requirements of different workpieces.

[0089] In this transmission process, the worm gear 701 has a larger transmission ratio, which can achieve more precise deceleration and torque amplification, so that the rotation of the drive disk 2 can be controlled more accurately, and has a certain self-locking characteristic. When the turning handle 702 stops, the position of the drive disk 2 can be kept stable to prevent the position of the splint 4 from changing unexpectedly due to external forces and other factors.

[0090] By utilizing the transmission characteristics of the worm 701 and the worm wheel 7, the position of the clamping plate 4 can be precisely adjusted.

[0091] In industrial production, accurate clamping position is crucial for some processing tasks with high precision requirements, such as laser cutting of precision parts.

[0092] The high precision and self-locking property of the worm 701 transmission can ensure that the clamping plate 4 is adjusted to the set position and stably maintained, reducing the cutting error caused by inaccurate clamping position and improving the processing accuracy and quality consistency of the product.

[0093] For example, in some metal frame cutting processes during the electronic chip manufacturing process, it is necessary to accurately control the position of the clamping plate 4 to ensure the cutting accuracy of the chip frame. The clamping and adjustment system driven by the worm 701 and the worm wheel 7 can well meet this requirement.

[0094] The design of the turning handle 702 allows the operator to conveniently manually control the position adjustment of the clamping plate 4 .

[0095] The operator only needs to turn the handle 702 to rotate the drive disc 2, thereby adjusting the clamping plate 4. Compared with some complex electric or hydraulic drive systems, this manual operation method is more intuitive and simple, does not require additional power sources and complex control systems, and reduces the cost and difficulty of operation of the equipment.

[0096] At the same time, due to the self-locking characteristics of the worm 701 transmission, after clamping is completed, even if it is subjected to a certain external force impact or vibration, the clamping plate 4 will not easily loosen or shift, thereby improving the safety of clamping, avoiding safety problems such as workpiece falling and cutting accidents caused by unstable clamping, and ensuring the personal safety of operators and the normal operation of equipment.

[0097] The transmission structure of the worm 701 and the worm wheel 7 is relatively compact and can be effectively integrated into the bottom space of the cutting table 1 without occupying too much external space, which is conducive to the miniaturization design of the overall structure of the equipment.

[0098] Moreover, the worm 701 and worm wheel 7 transmission has a high load-bearing capacity and good wear resistance. During long-term use, it can withstand a certain load and frequent operations, reducing equipment failures and maintenance frequency caused by wear of transmission parts.

[0099] For example, in some industrial production environments, laser cutting equipment needs to run continuously for a long time. This compact and durable worm 701 and worm wheel 7 clamping and adjusting device can work stably and reliably, reducing the maintenance cost and downtime of the equipment and improving production efficiency.
