Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, and in particular to a multifunctional laser processing machine tool. Background Technology

[0002] With the continuous improvement of modern industry's demand for processing precision, efficiency and multi-functional integration, in fields such as aerospace, electronic information, and precision machinery, facing complex materials and diversified processing tasks, single processing equipment is difficult to adapt to flexible and integrated production scenarios. In order to break through process bottlenecks and meet the requirements of high-end manufacturing for high efficiency, precision and multi-functional collaboration, multi-functional laser processing machine tools rely on the high energy density and non-contact processing advantages of laser technology, and integrate multi-process adaptable mechanical structures and control systems, and have gradually developed in response to the needs of industrial upgrading.

[0003] Existing multi-functional laser processing machine tools use high-energy laser beams as the core source of action. The laser emits lasers with specific wavelengths and powers, and the optical system precisely controls the beam parameters to focus the laser onto the surface of the workpiece to be processed. At the same time, based on a multi-axis motion platform, the workpiece or laser processing head is driven according to a preset program to achieve precise spatial displacement and attitude adjustment. During the processing, the laser beam acts on the workpiece material, and the photothermal effect causes the material to undergo physical changes such as melting and vaporization, completing various processing operations such as cutting, welding, and drilling. Through the coordinated control of laser energy, motion trajectory, and auxiliary conditions, precision processing tasks under different process requirements can be achieved.

[0004] However, existing multi-functional laser processing machine tools have poor fixture versatility during processing, and can only clamp workpieces of a single size specification. Furthermore, the stability and reliability of clamping are insufficient, making it difficult to guarantee processing accuracy and efficiency. Therefore, a multi-functional laser processing machine tool is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-functional laser processing machine tool, which aims to improve the problems of poor versatility of existing fixtures, which can only clamp workpieces of a single size and specification, and whose clamping stability and reliability are insufficient, making it difficult to guarantee processing accuracy and efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-functional laser processing machine tool, comprising a machine tool body, a mounting frame fixedly connected to the top of the machine tool body, a clamping assembly disposed above the machine tool body, a flattening assembly disposed on the right side of the clamping assembly, a laser processing device disposed above the clamping assembly, the clamping assembly comprising a cylinder fixedly connected inside the machine tool body, a base plate fixedly connected to the output end of the cylinder, two transmission blocks rotatably connected to both sides of the base plate, clamping blocks rotatably connected to the side walls of the transmission blocks, limit grooves being formed oppositely on the top of the machine tool body, a guide groove being formed on the top of the machine tool body, clamping plates being slidably connected to the opposite side walls of the clamping blocks, and at least one telescopic rod being fixedly connected to the side walls of the clamping plates, with a first spring sleeved on the surface of each telescopic rod;

[0007] As a further description of the above technical solution:

[0008] The flattening assembly includes a motor fixedly connected to the side wall of the mounting frame, a rotating rod fixedly connected to the output end of the motor, at least one cam fixedly connected to the surface of the rotating rod, a pressing plate abutting the bottom of the cam, and two guide columns fixedly connected inside the mounting frame, each guide column having a second spring sleeved on its surface.

[0009] As a further description of the above technical solution:

[0010] The base plate is slidably connected inside the machine tool body, and the clamping block is slidably connected inside the limiting groove;

[0011] As a further description of the above technical solution:

[0012] The clamping block is slidably connected inside the guide groove, and one end of the telescopic rod is fixedly connected inside the clamping block;

[0013] As a further description of the above technical solution:

[0014] One end of the first spring is fixedly connected to the inside of the clamping block, and the other end of the first spring is fixedly connected to the side wall of the clamping plate;

[0015] As a further description of the above technical solution:

[0016] The rotating rod is rotatably connected between the opposite inner walls of the mounting frame, and the pressure plate is slidably connected between the opposite side walls of the mounting frame;

[0017] As a further description of the above technical solution:

[0018] The pressure plate is slidably connected to the surface of the guide post;

[0019] As a further description of the above technical solution:

[0020] One end of the second spring is fixedly connected to the bottom of the pressure plate, and the other end of the second spring is fixedly connected to the inside of the mounting bracket.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, through the structural design of the clamping assembly, the cylinder drives the base plate, and the transmission block drives the clamping block to slide precisely along the limiting groove and guide groove to achieve initial clamping of the workpiece. The clamping plate inside the clamping block is combined with the telescopic rod and the first spring to form an elastic adaptive structure, which can not only adapt to workpieces of different sizes, but also make the clamping force uniform and stable through elastic buffering, effectively avoiding damage to the workpiece by rigid clamping. While ensuring the versatility and stability of clamping, it improves the positioning accuracy of the workpiece during processing, provides a reliable clamping foundation for laser processing, and solves the problems of poor versatility of existing clamps, which can only clamp workpieces of a single size and specification, and the insufficient stability and reliability of clamping, making it difficult to guarantee processing accuracy and efficiency.

[0023] 2. In this utility model, through the structural design of the flattening component, the cam is driven by a motor to rotate the rod, and the cam periodically presses against the flattening plate that is limited by the guide column. At the same time, the second spring provides elastic restoring force for the flattening plate, thus creating a stable and regular flattening action cycle. This design can continuously and evenly flatten the workpiece, effectively eliminating the warping caused by the workpiece's own deformation, creating a flat and stable working surface for laser processing, improving the quality of processed products, and enhancing the practicality of the multi-functional laser processing machine tool.

The clamping assembly 3 includes a mounting bracket 2 fixedly connected to the top of the machine tool body 1. Inside the machine tool body 1, there is a cylinder 31. The output end of the cylinder 31 is fixedly connected to a base plate 32, providing a stable power source for the base plate 32. Two transmission blocks 33 are rotatably connected to both sides of the base plate 32. Moving the transmission blocks 32 can drive the transmission blocks 33 to move. Each side wall of the transmission blocks 33 is rotatably connected to a clamping block 34. Moving the transmission blocks 33 can drive the clamping block 34 to move for clamping operations. The top of the machine tool body 1 has a limit groove 35 and a guide groove 36. The limit groove 35 and the guide groove 36 provide space for the clamping block 34 to move. The clamping block 34 is guided by a clamping plate 37 that is slidably connected to the inner sidewall of the clamping block 34. Each sidewall of the clamping plate 37 is fixedly connected to at least one telescopic rod 38. Each telescopic rod 38 is fitted with a first spring 39. The telescopic rod 38 and the first spring 39 provide elastic support for the clamping plate 37, so that the clamping plate 37 provides elastic support for the workpiece and prevents the clamping plate 37 from damaging the workpiece. The base plate 32 is slidably connected inside the machine tool body 1, and the machine tool body 1 provides movable space and movement guidance for the base plate 32. The clamping block 34 is slidably connected inside the limiting groove 35 and the guide groove 36. The limiting groove 35 and the guide groove 36 provide movement guidance for the clamping block 34 to prevent the clamping block 34 from shifting and causing problems with the clamping of the workpiece. One end of the telescopic rod 38 is fixedly connected to the inside of the clamping block 34, and the clamping block 34 provides stable support for the telescopic rod 38, so that the telescopic rod 38 can drive the clamping plate 37 to move stably. One end of the first spring 39 is fixedly connected to the inside of the clamping block 34, and the other end of the first spring 39 is fixedly connected to the side wall of the clamping plate 37, so that there is an elastic space between the clamping block 34 and the clamping plate 37. By utilizing the elastic property of the first spring 39, different workpieces can be elastically clamped.

[0032] Reference Figures 1-4The flattening assembly 4 includes a motor 41 fixedly connected to the side wall of the mounting frame 2. A rotating rod 42 is fixedly connected to the output end of the motor 41, providing a stable rotational power source for the rotating rod 42. At least one cam 43 is fixedly connected to the surface of the rotating rod 42. Rotation of the rotating rod 42 can drive the cam 43 to rotate. The bottom of the cam 43 abuts against a pressing plate 44. The cam 43 uses its own curved shape to drive the pressing plate 44 to move downward. Two guide posts 45 are fixedly connected inside the mounting frame 2, providing stable installation support for the guide posts 45. A second spring 46 is sleeved on the surface of each guide post 45. The rotating rod 42 is rotatably connected between the inner walls of the mounting frame 2. The motor 41 drives the rotating rod 42 to rotate inside the mounting frame 2, causing the cam 43 to rotate. The pressing plate 44 is slidably connected between the opposite side walls of the mounting frame 2. The mounting frame 2 provides space for the pressing plate 44 to move and flatten.

The guide post 45 provides movement guidance for the pressing plate 44 and prevents the pressing plate 44 from deviating during linear movement. One end of the second spring 46 is fixedly connected to the bottom of the pressing plate 44, and the other end of the second spring 46 is fixedly connected to the inside of the mounting frame 2. The second spring 46 enables the pressing plate 44 to automatically reset after the cam 43 is pressed down, so that the pressing plate 44 can continue to perform flattening work.

[0033] Working principle: During operation, motor 41 receives a command and outputs torque to drive rotating rod 42 to rotate. Rotating rod 42 drives cam 43 to rotate synchronously. Cam 43 periodically presses against pressing plate 44. Under the limiting guidance of guide column 45 inside mounting frame 2, pressing plate 44 reciprocates along the axial direction of guide column 45 to flatten the workpiece on the surface of machine tool body 1. During the flattening process, second spring 46 is compressed by pressing plate 44 and undergoes elastic deformation. When cam 43 rotates to a non-protruding part, second spring 46 releases elastic potential energy, pushing pressing plate 44 to reset, completing the flattening of the workpiece. Then, the workpiece is transferred between clamping plates 37. Cylinder 3 1. The base plate 32 is pushed to slide inside the machine tool body 1. The transmission blocks 33 on both sides of the base plate 32 move with the base plate 32. The transmission blocks 33 drive the clamping block 34 to slide along the direction of the limiting groove 35 and the guide groove 36, realizing the opening and closing action of the clamping block 34. At the same time, the clamping plate 37 on the inner side of the clamping block 34 is compressed by the first spring 39 through the telescopic rod 38 under the contact and pressure of the workpiece. The elastic buffer of the first spring 39 is used to make the clamping plate 37 stably fit with the workpiece, and complete the workpiece clamping. After the clamping is stable, the laser processing device 5 accurately controls the laser output according to the preset program to perform cutting, welding and other processing operations on the workpiece to complete the entire processing process.
