Description

Technical Field

[0001] This utility model relates to the field of support component processing and positioning technology, specifically to a positioning auxiliary device for laser surface hardening process of support components. Background Technology

[0002] As is well known, laser surface hardening is a key process in modern mechanical manufacturing. By rapidly heating and cooling the surface of a workpiece with a high-energy laser beam, it can significantly improve the surface hardness and wear resistance of support components. It is widely used in the strengthening treatment of machine tool guideways, bearing seats, hydraulic supports and other parts.

[0003] However, in actual quenching processes, the support components are complex in structure, diverse in size, and require stringent clamping and positioning accuracy. Traditional positioning devices are unable to meet the demands of efficient and high-precision processes.

[0004] Specifically, in existing technologies, conventional fixtures mostly adopt rigid fixed structures, using bolts or chucks to clamp the support in one direction. Although such devices can ensure basic stability, they often cannot achieve precise adjustment of multiple degrees of freedom, resulting in deviation of the laser beam incident angle, which in turn causes problems such as uneven quenching layer thickness and displacement of surface hardened areas. At the same time, the lack of real-time feedback and adjustment mechanisms makes it impossible to compensate for the slight displacement caused by thermal deformation during quenching, leading to the accumulation of processing errors.

[0006] To address the shortcomings of existing technologies, this utility model provides a positioning auxiliary device for the laser surface hardening process of support components.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a positioning auxiliary device for laser surface hardening process of a support component, comprising a base plate, a hydraulic telescopic rod at the upper end of the base plate, a support plate at the upper end of the hydraulic telescopic rod, an electric rotating column at the upper end of the support plate, a horizontal moving device at the upper end of the electric rotating column, an angle adjusting device at the upper end of the horizontal moving device, a clamping plate at the upper end of the angle adjusting device, control plates at four ends of the side wall of the clamping plate, a positioning device on the control plate, and a monitor for controlling the device at one corner of the side wall of the base plate.

[0009] To achieve contactless horizontal movement, the present invention is improved as follows: the horizontal movement device includes a positioning box, a magnetic slide rail and an electromagnetic block. The positioning box has a cavity without an upper side wall. The magnetic slide rail passes through the cavity. The electromagnetic block is on the magnetic slide rail and is electromagnetically slidably connected to it. The angle adjustment device is connected to the upper end of the electromagnetic block.

[0010] To precisely control the pitch angle of the clamping plate, the present invention includes the following improvements: the angle adjustment device includes a support frame, a rotating rod, and an adjusting motor. The rotating rod passes through both side walls of the support frame, the adjusting motor is located on one side wall of the support frame, and one end of the rotating rod is connected to the output end of the adjusting motor.

[0011] To ensure clamping stability, the present invention is improved as follows: the positioning device includes a limiting box, a rotating rod, a moving block, and a positioning plate. The limiting box is located on the outer wall of the control plate, the rotating rod passes through the limiting box, the moving block is on the rotating rod and threadedly connected to it, the moving block passes through the control plate and is slidably connected to it, the positioning plate is located at one end of the moving block, and a pressure sensor is provided on the positioning plate.

[0012] To achieve automatic telescopic control of the positioning plate, the present invention is improved as follows: a positioning motor is provided on the outer wall of the limiting box, and the rotating rod passes through the limiting box and is connected to the output end of the positioning motor.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a positioning auxiliary device for the laser surface hardening process of support components, which has the following beneficial effects:

[0018] This laser surface hardening process positioning auxiliary device for the support component is equipped with a hydraulic telescopic rod for vertical lifting (Z-axis), which works in conjunction with an electric rotating column to drive circumferential rotation and a magnetic slide rail for horizontal movement to achieve in-plane X / Y-axis translation. An angle adjustment device is also included, which adjusts the motor output to drive the rotating rod and clamping plate to rotate, allowing for adjustment of pitch and yaw angles. This forms a five-degree-of-freedom spatial positioning system, enabling irregularly shaped support components to be quickly adjusted to the optimal hardening posture. This avoids the problems of repeated disassembly and manual calibration caused by insufficient degrees of freedom in traditional fixtures, and is especially suitable for processing workpieces with complex geometric features.

[0019] In the positioning device, the screw-driven rotating rod and the moving block are combined with a pressure sensor to form a mechanical feedback closed loop. When the positioning motor drives the rotating rod to rotate, the moving block moves linearly along the thread, causing the positioning plate to contact the workpiece surface. The pressure sensor monitors the clamping force in real time and feeds it back to the control system to ensure that the clamping force is evenly distributed and there is no risk of overload, effectively suppressing the processing error caused by thermal deformation or mechanical vibration.

[0020] The monitor integrates a laser rangefinder and an infrared thermal imaging camera. The former detects the distance deviation between the workpiece and the laser head in real time, while the latter monitors the temperature field distribution in the quenching area and dynamically corrects the positioning parameters through the data processing module.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figure 1-4 A positioning auxiliary device for laser surface hardening process of support components includes a base plate 1, a hydraulic telescopic rod 4 at the upper end of the base plate 1, a support plate 5 at the upper end of the hydraulic telescopic rod 4, an electric rotating column 7 at the upper end of the support plate 5, a horizontal moving device at the upper end of the electric rotating column 7, an angle adjusting device at the upper end of the horizontal moving device, a clamping plate 10 at the upper end of the angle adjusting device, control plates 11 at four ends of the upper sidewall of the clamping plate 10, a positioning device on the control plate 11, and a monitor 3 for controlling the device at one corner of the upper sidewall of the base plate 1. The positioning device includes a limit box 12, a rotating rod 19, and a moving block 14. The control plate 11 includes a positioning plate 15, a limiting box 12 on the outer wall of the control plate 11, a rotating rod 19 passing through the limiting box 12, a moving block 14 on the rotating rod 19 and threadedly connected to it, a positioning plate 15 at one end of the moving block 14, a pressure sensor on the positioning plate 15, a positioning motor 13 on the outer wall of the limiting box 12, a rotating rod 19 passing through the limiting box 12 and connected to the output end of the positioning motor 13, a monitor 3 including a laser rangefinder and an infrared thermal imaging camera, and a wireless communication module and a data processing module.

[0030] During use, the support component to be processed (such as a bearing seat or guide rail) is placed in the center area of ​​the clamping plate 10. The positioning device is activated, and the positioning motor 13 drives the rotating rod 19 to rotate. Through threaded transmission, the moving block 14 slides along the control plate 11, and the four positioning plates 15 move synchronously towards the workpiece until the positioning plate 15 contacts the workpiece for clamping. The pressure sensor monitors the clamping force in real time. When the contact pressure reaches the preset threshold, the motor stops, completing the adaptive clamping and avoiding workpiece deformation or surface damage. The entire device is rigidly connected to the worktable of the laser processing equipment. Subsequently, the monitor 3 activates the laser rangefinder and infrared thermal imaging camera to collect real-time data on the distance between the workpiece surface and the laser head, as well as the temperature field distribution. The data processing module generates adjustment commands, and the hydraulic telescopic rod 4 adjusts according to the vertical distance fed back by the laser rangefinder. To mitigate errors, the support plate 5 is raised and lowered (Z-axis) to ensure the workpiece surface is within the laser focal depth range. The horizontal moving device moves laterally to match the scanning path. The electric rotating column 7 drives the clamping plate 10 and the workpiece to rotate around the vertical axis (θ-axis), adjusting the circumferential angle of the workpiece. This is suitable for uniform quenching of ring-shaped support components (such as bearing seats). The angle adjustment device changes the pitch angle of the clamping plate 10 so that the quenching area of ​​the irregularly shaped workpiece (such as the inclined guide rail) faces the laser incident direction, avoiding uneven energy distribution caused by tilting. During laser quenching, the monitor 3 works continuously, and the infrared thermal imaging camera captures the temperature changes on the workpiece surface. The data processing module predicts the deformation caused by thermal expansion and dynamically fine-tunes the angle adjustment device, horizontal moving device, or hydraulic telescopic rod 4 to correct position deviations in real time, ensuring the uniformity of the quenched layer and offsetting thermal deformation errors.

[0031] In practical use, it is necessary to be able to quickly respond to position adjustment needs and adapt to the positioning requirements of support components of different sizes. To meet the above requirements, in this embodiment, the horizontal moving device includes a positioning box 6, a magnetic slide rail 17, and an electromagnetic block 18. The positioning box 6 is provided with a cavity without an upper sidewall. The magnetic slide rail 17 passes through the cavity. The electromagnetic block 18 is on the magnetic slide rail 17 and is electromagnetically slidably connected to it. The angle adjustment device is connected to the upper end of the electromagnetic block 18.

[0032] The electromagnetic block 18 and the magnetic slide rail 17 form a contactless suspension through electromagnetic force. The principle is based on the property that like poles of magnets repel or opposite poles attract. Through the interaction between the electromagnetic coil embedded in the magnetic slide rail 17 and the permanent magnet / electromagnet in the electromagnetic block 18, a levitation force perpendicular to the track direction is generated to overcome gravity. At the same time, a controllable electromagnetic thrust is applied in the horizontal direction to drive the electromagnetic block 18 to slide.

[0033] In practical use, it is necessary to accurately control the pitch angle of the clamping plate 10. To meet the above requirements, in this embodiment, the angle adjustment device includes a support frame 8, a rotating rod 9, and an adjusting motor 16. The rotating rod 9 passes through both side walls of the support frame 8, and the adjusting motor 16 is located on one side wall of the support frame 8. One end of the rotating rod 9 is connected to the output end of the adjusting motor 16.

[0034] Adjust the output of motor 16 to drive the rotating rod 9 to deflect, and the clamping plate 10 will rotate and tilt accordingly.

[0035] In practical use, it is necessary to be able to connect to external devices to enhance the overall stability of the device. To meet the above requirements, in this embodiment, the base plate 1 is provided with multiple sets of fixing screws 2.

[0036] The fixing screw 2 is inserted through the base plate 1 and the laser processing equipment to ensure that the device does not shift as a whole during subsequent dynamic adjustments.
