Before subsequent machining processes such as milling and drilling, datum lines, machining boundary lines, or feature marking lines need to be drawn on its end faces, outer diameters, and other surfaces to provide accurate references for machining operations. Currently, motor housing scribing devices for machine tools mainly use a drive structure to move the scribing cutter head to achieve scribing operations on the motor housing. Common drive structures include linear motors, lead screws, and slides, which can drive the scribing cutter head to complete scribing operations on straight lines, circles, or complex trajectories. They are indispensable auxiliary equipment in the motor housing machining process.

[0003] However, the scribing cutter head in existing scribing devices is usually fixedly connected to the structure that drives its movement (such as the output end of a linear motor), for example, by welding or multiple sets of bolts. This connection method makes the disassembly and replacement of the scribing cutter head cumbersome, requiring the use of special tools to remove the fixing parts, which increases the labor intensity of operators and affects work efficiency. Utility Model Content

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Reference Figure 1 - Figure 4 As shown, a scribing device for a machine tool motor housing is provided, including a worktable 1. A rotary clamping assembly 26 is provided on one side of the top of the worktable 1. In this example, the rotary clamping assembly 26 consists of a gantry frame, a hydraulic cylinder, a rotating seat, a clamping plate, and a rotary motor, so as to clamp and fix the workpiece and drive the rotating seat to rotate the workpiece, which facilitates scribing around its circumference. The rotary clamping assembly 26 is a prior art and will not be described in detail. An adjustment mechanism is provided at the rear of the rotary clamping assembly 26. A linear motor 2 is connected to the front of the adjustment mechanism. The moving end of the linear motor 2 is connected to a movable rod 4, and one end of the movable rod 4 is connected to a scribing cutter head 3 through a fixing mechanism. The rotary clamping assembly 26 can stably clamp the motor housing and drive it to rotate. In conjunction with the linear motor 2, it drives the scribing cutter head 3 to move, which can meet the scribing requirements of different trajectories and improve the applicability of scribing. The fixing mechanism includes a plug 5, which is fixedly connected to one end of the scribing head 3. One end of the movable rod 4 has a slot 6 that matches the plug 5. A sliding sleeve 7 is slidably fitted on the outer side of the movable rod 4. Several mounting grooves 9 are symmetrically opened on the inner wall of the slot 6. Ball bearings 8 are installed in the mounting grooves 9. Several slots that match the ball bearings 8 are symmetrically opened on the outer wall of the plug 5. Through the precise matching of the plug 5 and the slot 6, combined with the locking action of the ball bearings 8 and the slots, the scribing head 3 can be quickly positioned, laying the foundation for subsequent quick disassembly and assembly.

[0017] In this example, the fixing mechanism also includes a baffle 10, which is fixedly sleeved on the outside of the movable rod 4. A reset groove 13 is opened on the inner wall of one end of the sliding sleeve 7, and the baffle 10 is located in the reset groove 13. A spring 11 is sleeved on the outside of the movable rod 4 in the reset groove 13, and the spring 11 is located on the side of the baffle 10 close to the scribing head 3. With the help of the elastic force of the spring 11, the sliding sleeve 7 can be driven to automatically reset, without the need to manually adjust the position of the sliding sleeve 7, simplifying the installation process of the scribing head 3 and reducing the difficulty of operation.

[0018] In this example, the inner wall of the reset groove 13 is symmetrically provided with several guide rails 12, and the guide rails 12 pass through the baffle 10. The guide rails 12 are slidably connected to the baffle 10. The end of the sliding sleeve 7 away from the baffle 10 is provided with a pressing groove 14. The guide rails 12 can accurately guide the sliding direction of the sliding sleeve 7 to avoid the sliding sleeve 7 from deviating and affecting the pressing effect of the ball 8. The pressing groove 14 can smoothly drive the ball 8 to engage or disengage from the slot, ensuring smooth and efficient disassembly and assembly.

[0019] In this example, two magnets 16 are sleeved on the outer side of the baffle 10, and the two magnets 16 are respectively connected to one end of the sliding sleeve 7 and one end of the linear motor 2. A protective cover 15 is sleeved on the outer side of one end of the sliding sleeve 7, and one end of the protective cover 15 is connected to one end of the linear motor 2. The repulsive force generated by the two magnets 16 with the same pole can stabilize the position of the sliding sleeve 7 and prevent the sliding sleeve 7 from loosening during the scribing process. The protective cover 15 can prevent metal debris from adsorbing on the surface of the magnets 16, ensuring the stability of the component operation and service life.

[0020] In this example, the adjustment mechanism includes a support frame 17, which is located on one side of the top of the workbench 1. A screw 18 is rotatably installed inside the support frame 17. A servo motor 19 is connected to the top of the support frame 17 at the upper end of the screw 18. A slider 20 is threadedly connected to the outer wall of the screw 18. A support frame 21 is hinged to the front end of the slider 20. A servo motor 22 connected to the support frame 21 is provided on the top of the slider 20. A linear motor 2 is fixedly installed on one side of the support frame 21. The height of the scribing head 3 can be precisely adjusted by driving the screw 18 through the servo motor 19. The servo motor 22 can flexibly adjust the horizontal angle of the scribing head 3 to meet the scribing requirements of different inclined surfaces of the motor housing and improve scribing accuracy.

[0021] In this example, an adjustment groove 25 is provided on one side of the top of the workbench 1, and an adjustment block 24 is slidably installed in the adjustment groove 25. A telescopic rod 23 is fixedly installed on the back of the workbench 1, and the telescopic end of the telescopic rod 23 is fixedly connected to the adjustment block 24. An inclined through groove is provided on the back of the workbench 1. The telescopic rod 23 can drive the adjustment block 24 to move the support frame 17 back and forth, so as to realize the flexible adjustment of the front and back position of the scribing head 3, adapt to scribing operations of motor housings of different specifications, and enhance the versatility of the device.

[0022] During use, the workpiece is fixed and rotated: the motor housing is firmly clamped by the rotating clamping assembly 26 on the top of the worktable 1, and the rotating clamping assembly 26 can drive the workpiece to rotate, providing a basis for scribing operations at different angles.

[0023] Scribing position adjustment: In the adjustment mechanism, the servo motor 19 drives the screw 18 to rotate forward and backward, which drives the slider 20, support frame 21 and linear motor 2 to rise and fall, thereby realizing the height adjustment of the scribing head 3; the servo motor 22 drives the support frame 21 to rotate, thereby completing the horizontal angle adjustment of the scribing head 3; the telescopic rod 23 pushes and pulls the adjustment block 24 to slide along the adjustment groove 25, thereby driving the support frame 17 to move back and forth, thereby realizing the back and forth position adjustment of the scribing head 3, which can fully adapt to scribing needs.

[0024] Marking operation: The linear motor 2 drives the movable rod 4 to move the marking cutter head 3. In conjunction with the rotation of the workpiece, the marking cutter head 3 marks the required reference lines, processing boundary lines and other marking lines on the surface of the motor housing.

[0025] Disassembly and assembly of scribing cutter head 3: During disassembly, push the sliding sleeve 7 to slide along the guide rail 12, squeeze the spring 11 until the squeezing groove 14 does not obstruct the ball 8, and then pull out the insert block 5 and scribing cutter head 3; During installation, insert the insert block 5 into the slot 6, release the sliding sleeve 7, the spring 11 drives the sliding sleeve 7 to return to its original position, the squeezing groove 14 pushes the ball 8 into the slot of the insert block 5, and completes the fixation; at the same time, the two like-pole magnets 16 on the outside of the baffle 10 generate a repulsive force to stabilize the position of the sliding sleeve 7, and the protective cover 15 blocks metal debris to ensure stable operation of the components.
