Description

Technical Field

[0001] This invention relates to the field of cutting and processing technology, specifically to a cutting and processing device for automotive chassis parts. Background Technology

[0002] With the development of modern machining industry, the requirements for cutting quality and precision are constantly increasing. The requirements for improving production efficiency, reducing production costs, and having highly intelligent automatic cutting functions are also rising. The development of CNC cutting machines must adapt to the requirements of modern machining industry.

[0003] For example, Chinese patent publication number CN220805648U discloses a "cutting machine for processing automotive interior parts," whose main structure includes a dust collection mechanism, a cutting mechanism, and a clamping mechanism. The cutting mechanism is located above the dust collection mechanism, and the clamping mechanism is also located above the cutting mechanism. The dust collection mechanism includes a worktable, with a dust collection hood fixedly connected to the upper surface of the worktable. A dust collection pipe is fixedly connected to the rear end of the dust collection hood, and a dust collection pump is fixedly connected to the lower end of the dust collection pipe. A dust outlet pipe is fixedly connected to the left side of the dust collection pump, and the left side of the dust outlet pipe extends into the collection box. In this cutting machine for processing automotive interior parts, the dust collection pump creates negative pressure inside the dust collection pipe, absorbing the dust generated during cutting. The collection hood covers the dust, preventing it from flying around and reducing its impact on the health of workers. The dust is then transported to the collection box through the dust outlet pipe, where it is collected. Finally, the collection box is opened and removed for cleaning.

[0004] In actual processing, multi-angle cutting is often required to adapt to the adaptability of automotive parts in terms of cutting angle. However, when the aforementioned cutting machine for processing automotive interior parts cuts the parts, the rotating disc cutter can only produce longitudinal angular displacement, which results in the cutting angle being limited to longitudinal cutting and making the cutting angle very singular.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1 and Figure 2 A cutting and processing device for automotive chassis parts includes a drive motor 1 with a rotating disc cutter 2 mounted on the rotor end and a top mounting base 3 located above the drive motor 1. First, the second liquid docking channel 53 and the first liquid docking channel 46 are respectively connected to the liquid circuit of the hydraulic pump station through independent three-position four-way solenoid directional valves. During operation, the system first drives the directional valve corresponding to the second liquid docking channel 53 to inject liquid to lock the rotating ball 510. After locking, the system then drives the directional valve corresponding to the first liquid docking channel 46 to inject liquid to execute the cutting feed, thereby decoupling the angle adjustment and feed processes. Then, the top mounting base 3 is fixedly installed on the corresponding position of the worktable with bolts. Then, the automotive parts to be cut are fixedly clamped by the clamping device, and the drive motor 1 can be started. Its rotor will drive the rotating disc cutter 2 to rotate rapidly, and the automotive parts are cut by the rapidly rotating rotating disc cutter 2.

[0023] To achieve the required cutting stroke supply, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 A hydraulic feeding mechanism 4 needs to be installed. Its structure includes a telescopic cylinder 41 with a hollow internal structure, which is fixedly installed below the top mounting base 3; a piston plate 47 placed inside the telescopic cylinder 41 and moving downward under liquid pressure; a longitudinal telescopic rod 48 that moves with the piston plate 47 and can provide cutting feed to the rotating disc cutter 2; and a first helical spring 49 placed inside the telescopic cylinder 41 and capable of resetting the piston plate 47 upward. When the hydraulic equipment is started, liquid enters the liquid limiting chamber 44 through the first liquid docking channel 46. When the liquid pressure is greater than the elastic strength of the first helical spring 49, the first helical spring 49 is compressed, and the piston plate 47 moves downward under hydraulic pressure. The longitudinal telescopic rod 48 will drive the rotating disc cutter 2 to move toward the cutting position of the automotive parts through the drive motor 1, thereby realizing the cutting stroke supply.

[0024] For details regarding the specific structure of the hydraulic feed mechanism 4, please refer to [link / reference]. Figure 3 and Figure 4It also includes a first connecting plate 42 integrally disposed on the top of the telescopic cylinder 41. The telescopic cylinder 41 has a first movable chamber 43 inside. The top center of the first movable chamber 43 has a liquid limiting chamber 44. The bottom center of the first movable chamber 43 has a rod through hole 45 communicating with the outside space. The circumferential side of the telescopic cylinder 41 has a first liquid docking channel 46 communicating with the liquid limiting chamber 44.

The longitudinal telescopic rod 48 has a first helical spring 49 in a compressed state sleeved around the rod body located inside the first movable cavity 43. The bottom end of the longitudinal telescopic rod 48 is provided with a motor fixing sleeve 410 integrally formed with it. The sleeve hole of the motor fixing sleeve 410 is fixedly installed on the periphery of the drive motor 1.

[0025] To achieve a wide range of cutting angle adjustment, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 5 and Figure 6 A universal angle adjustment mechanism 5 needs to be installed. Its structure includes two symmetrically arranged, hollow hemispherical shells 56, a rotating ball 510 installed inside the hemispherical shells 56 and capable of rotation, an elastic liquid membrane 59 installed inside the hemispherical shells 56 and capable of locking the rotating ball 510, and a hollow connecting rod 51 capable of generating liquid pressure on the elastic liquid membrane 59. A handheld motor fixing sleeve 410 is used, and then the rotating disc cutter 2 is manually adjusted so that the cutting angle and feed direction of the rotating disc cutter 2 are along the cutting direction. Then... Liquid is injected into the liquid compression chamber 52 by hydraulic equipment. When the liquid exerts pressure on the elastic liquid film 59, the elastic liquid film 59 will wrap around the outer circumference of the rotating ball 510. When the maximum static friction force formed by this pressure reaches the threshold, the rotating ball 510 will be locked under the action of this friction force. Since the angles of the two sets of hemispherical shells 56 and the rotating ball 510 are matched, a secondary cutting angle adjustment can be performed on the basis of the initial cutting angle adjustment, thereby further expanding the equipment's function of adjusting the cutting angle and cutting position.

[0026] For details regarding the specific structure of the universal angle adjustment mechanism 5, please refer to [link / reference]. Figure 5 and Figure 6It also includes a liquid compression chamber 52 disposed inside the hollow connecting rod 51. A second liquid docking channel 53 and a third liquid docking channel 54, connecting the liquid compression chamber 52, are disposed in the middle of the outer circumference of the hollow connecting rod 51. A hemispherical outer shell 56, integrally formed with the hollow connecting rod 51, is disposed at each end of the hollow connecting rod 51. An inwardly recessed hemispherical inner cavity 57 is disposed inside the hemispherical outer shell 56. A spherical chamber 58 is disposed around the hemispherical inner cavity 57. An elastic liquid film 59 is embedded in the hemispherical outer shell 56 at the junction of the hemispherical inner cavity 57 and the spherical chamber 58. The spherical chamber 58 and the corresponding liquid compression chamber 52 are connected through a liquid flow hole 55. A freely rotating ball is placed in the hemispherical inner cavity 57. The rotating sphere 510 has an axial connecting rod 511 integrally formed with it on one side. The end of the axial connecting rod 511 has a second connecting plate 512 integrally formed with it. The upper second connecting plate 512 is fixedly connected to the bottom of the top mounting base 3, and the lower second connecting plate 512 is fixedly connected to the top of the first connecting plate 42. The structural radius of the rotating sphere 510 matches the structural radius of the hemispherical inner cavity 57, and the depth of the hemispherical inner cavity 57 is greater than the structural radius of the rotating sphere 510 and less than the structural diameter of the rotating sphere 510. During operation, the second liquid docking channel 53 and the first liquid docking channel 46 are connected to the liquid circuit of a hydraulic device that can control the direction and pressure of liquid flow through pipes.

[0027] To prevent equipment damage due to liquid pressure overload, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 7 and Figure 8An adjustable pressure control mechanism 6 is required. Its structure includes a hollow shell 61 fixedly installed at the end of the third liquid docking channel 54 and having a hollow internal structure; a first valve plate 65 placed inside the hollow shell 61 and capable of controlling the opening and closing of the liquid flow; a second helical spring 610 placed inside the hollow shell 61 and capable of providing elastic damping to the first valve plate 65; and a second valve plate 69 placed inside the hollow shell 61 and capable of changing the elastic strength of the second helical spring 610. Liquid entering the liquid compression chamber 52 will exert directional pressure on the first valve plate 65 through the fourth liquid docking channel 63. When this pressure exceeds the elastic strength of the second helical spring 610, it will cause the second helical spring 610 to be compressed, while the first valve plate 65 will shift. During the movement phenomenon, the liquid inside the liquid compression chamber 52 will be discharged outward sequentially along the fourth liquid docking channel 63, the movement gap of the first valve plate 65, the liquid flow groove 68, the second moving chamber 62, and the liquid discharge hole 613. At this time, the high-pressure liquid inside the liquid compression chamber 52 will be depressurized in time, thereby preventing the equipment from being damaged due to liquid pressure overload. When it is necessary to adjust the control pressure, rotate the knob cap 612 in a directional manner. At this time, the external thread rod 611 will rotate accordingly. Due to the threaded connection, the second valve plate 69 will move relative to the first valve plate 65. The compression stroke of the second helical spring 610 will change. Therefore, the elastic strength of the second helical spring 610 relative to the first valve plate 65 will change, and the threshold of the mechanism will change accordingly, thereby realizing the pressure adjustment function.

[0028] For details regarding the structure of the adjustable pressure control mechanism 6, please refer to [link / reference]. Figure 7 and Figure 8It also includes a second movable cavity 62 disposed inside the hollow shell 61. One end of the hollow shell 61 is provided with a fourth liquid docking channel 63, which is integrally formed with the second movable cavity 62 and connects one end of the third liquid docking channel 54. The other end of the hollow shell 61 is provided with an internal threaded hole 64. The second movable cavity 62 contains a first valve plate 65 and a second valve plate 69 that can move along its axial direction. The first valve plate 65 is close to the fourth liquid docking channel 63, and the second valve plate 69 is close to the internal threaded hole 64. The first valve plate 65 has a recessed embedding groove 66 on its end face facing the fourth liquid docking channel 63. A sealing gasket 67 is embedded in the embedding groove 66. The circumferential sides of the first valve plate 65 and the second valve plate 69 are provided with multiple recessed liquid flow grooves 68. A second helical spring 610 in a compressed state is placed between the second valve plate 69 and the second valve plate 64. An external threaded rod 611 is installed in the internal threaded hole 64 through a threaded structure. One end of the external threaded rod 611 located inside the second movable cavity 62 is installed inside the second valve plate 69 through a bearing. A knob cap 612 is fixedly fitted to the other end of the external threaded rod 611. One end of the hollow housing 61 is provided with a liquid discharge hole 613 for discharging liquid. The depth of the embedded groove 66 is less than the thickness of the sealing gasket 67, and the structural radius of the sealing gasket 67 is greater than the structural radius of the inner hole of the fourth liquid docking channel 63. The threaded structure includes an internal thread structure set on the inner wall of the internal threaded hole 64 and an external thread structure set on the rod body of the external threaded rod 611, and the internal thread structure matches the external thread structure.

[0029] In use, the second liquid docking channel 53 and the first liquid docking channel 46 are respectively connected to the liquid circuit of the hydraulic pump station through independent three-position four-way solenoid directional valves. During operation, the system first drives the directional valve corresponding to the second channel to inject liquid to lock the rotating ball 510. After locking, it drives the directional valve corresponding to the first channel to inject liquid to execute the cutting feed, thus decoupling the angle adjustment and feed processes. Then, the top mounting base 3 is fixedly installed on the corresponding position of the worktable with bolts. Then, the automotive parts to be cut are fixed and clamped by the clamping device, and the drive motor 1 can be started. Its rotor will drive the rotating disc cutter 2 to rotate rapidly. Hold the motor fixing sleeve 410 and then manually adjust the rotating disc cutter 2 so that the cutting angle and feed direction of the rotating disc cutter 2 are along the cutting direction. Then, liquid is injected into the liquid compression chamber 52 through the hydraulic device. When the body exerts pressure on the elastic liquid membrane 59, the elastic liquid membrane 59 will wrap around the outer circumference of the rotating ball 510. When the maximum static friction force formed by this pressure reaches the threshold, the rotating ball 510 will be locked under the action of this friction force. After the angle locking is completed, the hydraulic equipment is started, and the liquid enters the liquid limiting cavity 44 through the first liquid docking channel 46. When the liquid pressure is greater than the elastic strength of the first helical spring 49, the first helical spring 49 is compressed, and the piston plate 47 moves downward under hydraulic pressure. The longitudinal telescopic rod 48 will drive the rotating disc cutter 2 to move toward the cutting position of the automotive parts through the drive motor 1, and the automotive parts are cut by the rapidly rotating disc cutter 2.
