Description

Technical Field

[0001] This invention relates to the technical field of spacer bar processing equipment, and more particularly to a CNC milling machine for milling spacer bar-shaped joints and the spacer bar thereof. Background Technology

[0002] Ultra-high voltage transmission line conductor spacers are classified as damped spacers and undamped spacers. During the operation of 500kV transmission lines, conductor spacers must be in perfect physical condition. The "Operation Regulations for Overhead Transmission Lines" stipulate that spacer inspections should be conducted every two years. Spacers may develop problems during prolonged operation; any defective spacers must be replaced promptly.

[0003] In existing technology, when processing spacers, the spherical joints of the spacers need to be ground and deburred before the spacers are formed. During the grinding and deburring process, the operator needs to manually refine the spacers so that one side of the spacers comes into contact with the grinding wheel. As a result, the grinding and deburring process at the edge of the spacers is very inconvenient and the grinding effect is poor. Summary of the Invention

[0036] Example 1

[0037] Reference Figures 1-9 The first embodiment of the present invention provides a CNC milling device for milling intermittent baseball-shaped joints, including a support component 100, which is the basic structure of the device. In this embodiment, the support component 100 includes a machine tool 101 and a gripping component 102 disposed on the support box. The machine tool 101 is an existing electrically controlled machine tool used for milling and other operations on parts.

[0038] In this embodiment, the machine tool 101 includes a main support base plate 101a and a processing area. The main support base plate 101a is made of high-strength cast iron to ensure the stability of the supporting parts during the processing. The processing area is the core space for milling operations on the spacer bar. It is in the shape of a box frame and is set on the main support base plate 101a.

[0039] Furthermore, the present invention also includes a milling assembly 200, which is used to mill the spherical joint 601 of the spacer bar. In this embodiment, the milling assembly 200 includes a rotating component 201 disposed on the gripping component 102 and a cutting tool 202 disposed on the machining tool 101. The rotating component 201 can drive the spacer bar to rotate at multiple angles to ensure that each surface of the spherical joint 601 can be milled uniformly. A cutting tool moving component is disposed on the rotating component 201 to adjust the position of the cutting tool 202 to adapt to the processing requirements of spherical joints 601 of different sizes.

[0040] Furthermore, the present invention also includes a finishing component 400, which is disposed on the machining tool 101. The finishing component 400 is used to perform fine finishing on the milled ball joint 601 to improve surface finish and dimensional accuracy.

[0041] Furthermore, the gripping component 102 is used to fix the spacer bar. In this embodiment, the gripping component 102 includes a processing gantry 102a disposed on the processing machine tool 101, a clamping block 1021 disposed on the processing gantry 102a, a clamping plate 102b disposed at the lower end of the clamping block 1021, a plurality of clamping claws 102c disposed on the clamping plate 102b, and friction particles disposed on the clamping claws 102c. A clamping groove 102d is provided on the clamping plate 102b. A pneumatic telescopic rod 102e is disposed between the clamping claws 102c and the clamping block 1021. A block-shaped structure extends out from the rear end of the clamping plate 102b and is hinged to the pneumatic telescopic rod 102e.

[0042] In this embodiment, the rotating component 201 includes a rotating motor 201a disposed on the clamping block 1021, and the rotating motor 201a is connected to the clamping plate 102b.

[0043] Preferably, a groove is formed at the center of the clamping plate 102b for mounting the spacer bar. There are four clamping claws 102c, which are evenly distributed around the clamping plate 102b. The lower end of the clamping plate 102b extends downward, and a clamping groove 102d is formed on the lower end of the clamping plate 102b. The clamping groove 102d is arrayed along the lower end of the clamping plate 102b and is used for the rotational connection of the clamping claws 102c. An arc-shaped clamping plate is rotatably connected to the inner surface of the clamping claws 102c. The arc-shaped clamping plate can better fit the outer surface of the spacer bar. When the arc-shaped clamping plates on the four clamping claws 102c come close to each other, they form a cylindrical clamping space for clamping the spacer bar.

[0044] Preferably, a pneumatic telescopic rod 102e is provided between the clamping claw 102c and the clamping block 1021. The extension and retraction of the pneumatic telescopic rod 102e can drive the clamping claw 102c to open and close, thereby clamping and releasing the spacer.

[0045] Furthermore, the friction particles on the gripper 102c are made of rubber and are fixed to the inner surface of the gripper 102c with adhesive. This increases the friction between the gripper 102c and the spacer bar, preventing the spacer bar from sliding during processing and ensuring processing accuracy.

[0046] Furthermore, the cutting tool 202 is the execution component for milling. In this embodiment, the cutting tool 202 includes a tool holder 202a disposed on the machine tool 101 corresponding to the machining gantry 102a, a mounting plate 202b disposed on the tool holder 202a, and a milling cutter 202c disposed on the mounting plate 202b. The tool holder 202a is fixed to the machining area of ​​the machine tool 101 by welding and is disposed opposite to the machining gantry 102a to ensure that the cutting tool 202 can be accurately aligned with the ball joint 601 of the spacer bar.

[0047] Furthermore, a slider 202d is provided at the rear end of the milling cutter 202c, and a slide rail 202e is provided on the tool holder 202a for the slider 202d to slide. A ball bearing is provided between the slider 202d and the slide rail 202e to reduce the friction during the sliding process and make the movement of the milling cutter 202c smoother. A drive component 300 is provided on the slider 202d to drive the milling cutter 202c to move along the slide rail 202e.

[0048] Preferably, the slide rail 202e is set to be arc-shaped, and the curvature of the slide rail 202e is consistent with the curvature of the target spherical joint 601.

[0049] Furthermore, the driving component 300 includes a driving wheel 301 mounted on the slider 202d, an external gear 302 mounted on the driving wheel 301, a rack 303 mounted on the slide rail 202e and meshing with the external gear 302, and a stop 304 mounted on the slide rail 202e. The driving wheel 301 is driven by a servo motor, which is fixed to the mounting plate 202b by bolts. The servo motor can precisely control the speed and rotation angle of the driving wheel 301. There are two driving wheels 301, symmetrically arranged at both ends of the mounting plate 202b. There are two racks 303, which are also arranged along the arc of the slide rail 202e. Each rack 303 meshes with the gear of one driving wheel 301. When the servo motor rotates, it drives the driving wheel 301 to rotate, thereby realizing its movement on the rack 303 and ensuring that the milling tool 202c can perform machining along the surface of the ball joint 601.

[0050] Furthermore, a baffle 305 is provided on the baffle 304, forming a space between the baffle 305 and the baffle 304 for the drive wheel 301 to enter, which can limit the movement range of the drive wheel 301 and prevent the drive wheel 301 from disengaging from the slide rail 202e. A drive shaft 306 is provided between the drive wheel 301 and the mounting clamp 202b, and the drive shaft 306 is connected to the drive wheel 301 by a key, transmitting the power of the servo motor to the drive wheel 301. A sliding hole 307 is provided on the baffle 305 for the drive shaft 306 to slide, and the length of the sliding hole 307 is adapted to the length of the slide rail 202e to ensure that the drive shaft 306 can move together with the drive wheel 301.

[0051] Furthermore, in this embodiment, the finishing component 400 includes a bracket 400a disposed on the main receiving base plate 101a, a receiving ball 401 rotatably connected to the bracket 400a, a milling hemisphere 402 disposed within the receiving ball 401, and a plurality of milling scrapers 403 disposed within the milling hemisphere 402. The receiving ball 401 is rotatably connected to the bracket 400a via a rotating shaft, facilitating finishing of the milled spherical joint 601. The milling scrapers 403 are disposed on the guard plate 404. The milling scrapers 403 are made of high-speed steel, which has high hardness and wear resistance, and can finely scrape the surface of the spherical joint 601. A plurality of guard plates 404 are disposed within the milling hemisphere 402, and each guard plate 404 is provided with multiple milling scrapers 403. The guard plates 404 are made of stainless steel.

[0052] Furthermore, a rotating shaft 405 is provided at the rear end of each guard plate 404. The rotating shaft 405 extends outward from the milling hemisphere 402. A bearing is provided between the rotating shaft 405 and the milling hemisphere 402 to reduce the friction when the rotating shaft 405 rotates. A control component is provided on the milling hemisphere 402 to control the rotation of the rotating shaft 405, which is used to adjust the angle and position of the milling scraper 403.

[0053] Furthermore, in this embodiment, the control component includes a connecting collar 405a disposed outside each rotating shaft 405. The connecting collar 405a is connected to the outer wall of the milled hemisphere 402 by bolts. A connecting ring 405b is also connected to the rotating shaft 405. A connecting rod 405c extends downward from the side wall of the connecting ring 405b. The connecting rod 405c extends downward and rotates with the rotating shaft 405. A driven connecting rod 405d is hinged between the lower ends of every two connecting rods 405c. Both ends of the driven connecting rod 405d are hinged. Thus, it is possible to drive the rotation of only one rotating shaft 405 to drive the rotation of the other rotating shafts 405.

[0054] Keys are symmetrically arranged on the rotating shaft 405, with two keyes positioned in the radial diameter direction of the rotating shaft 405. A keyway cooperating with the key is also provided on the connecting ring 405b. A bracket 400a is also provided on the main supporting base plate 101a, and a motor 405e is mounted on the bracket 400a. The motor 405e controls the rotation of the rotating shaft 405. When the motor 405e drives the rotating shaft 405 to rotate, it simultaneously drives the connecting rod 405c to rotate. The rotation of the connecting rod 405c pushes the lower driven connecting rod 405d to slide linearly. The sliding of the driven connecting rod 405d drives the rotation of the next connecting rod 405c, and so on, achieving the rotation of all the connecting rods 405c, thereby driving the rotation of several rotating shafts 405, and ultimately realizing the rotation of the guard plate 404.

[0055] Furthermore, a control rod 406 is rotatably connected to the bracket 400a. The control rod 406 is connected to the bracket 400a through a bearing and can rotate around its own axis. A locking rod 407 extends from the control rod 406 and is welded to the control rod 406. The locking rod 407 can rotate together with the control rod 406. An arc plate 408 is provided at the end of the control rod 406.

[0056] Preferably, the end of the lever 407 is bent, and the curvature of the bend is consistent with the curvature of the receiving ball 401. A drive rod 409 is provided at the end of the lever 407. The extension direction of the drive rod 409 is the radial direction of the receiving ball 401. The drive rod 409 and the lever 407 are connected by threads, and the length of the drive rod 409 can be adjusted. Several drive grooves 500 and circular grooves 501 are provided on the receiving ball 401. The drive grooves 500 and circular grooves 501 are intermittently arranged. The drive grooves 500 are opened along the surface of the receiving ball 401 and are adapted to the movement trajectory of the lever 407.

[0057] Preferably, the arc plate 408 rotates and enters the circular groove 501. The arc plate 408 is arranged opposite to the clamping rod 407, wherein the arc plate 408 only serves as a guide.

[0058] Furthermore, several side grooves 700 are formed on the milled hemisphere 402, and side baffles 701 are slidably connected in the side grooves 700. Each side baffle 701 is connected to a guard plate 404, and each connecting collar 405a is correspondingly set with the side baffle 701.

A pneumatic actuator 703 is set between the side grooves 700 and the side baffles 701. The pneumatic actuator 703 can push the side baffles 701 to extend and slide. Several pneumatic actuators 703 are provided.

[0059] Furthermore, in this embodiment, the tool moving component includes a first motor 502 disposed at the rear end of the control lever 406. The first motor 502 is connected to the control lever 406 via a coupling and can drive the control lever 406 to rotate.

[0060] Furthermore, a drive guide rail 503 is provided on the processing gantry 102a, a drive block 504 is slidably connected on the drive guide rail 503, a slide plate 504a is provided on the drive block 504, a connecting cylinder 504b is provided on the slide plate 504a, the clamping block 1021 is rotatably connected to the connecting cylinder 504b, a ball screw 505 connected to the drive block 504 is provided on the drive guide rail 503, and a stepper motor 506 for driving the ball screw 505 to rotate is provided on the drive guide rail 503.

[0061] Furthermore, the slide plate 504a and the drive block 504 are slidably connected in the vertical direction, and a vertical groove is provided on the drive block 504.

[0062] Preferably, a second cylinder is provided on the drive block 504 to drive the slide plate 504a to slide. The piston rod of the second cylinder is connected to the slide plate 504a by a pin, which can drive the slide plate 504a to move in the vertical direction.

[0063] Operation process: First, the main body 600 of the spacer bar is placed in the circular groove 501 of the clamping plate 102b. The clamping jaws 102c are closed by the pneumatic telescopic rod 102e, and the spacer bar is clamped by the friction particles on the clamping jaws 102c. Then, the first cylinder 507 pushes the drive block 504 to move along the drive guide rail 503, and the second cylinder drives the slide plate 504a to move vertically, adjusting the ball joint 601 of the spacer bar to the machining position of the milling assembly 200.

[0064] Next, the drive unit 300 drives the milling cutter 202c to move along the arc-shaped slide rail 202e, while the rotating component 201 drives the milling cutter 202c to move, so that the milling cutter 202c performs milling on the spherical joint 601. After milling is completed, the second cylinder at the rear end of the machining gantry 102a is activated to lift the slide plate 504a upward. Then, the stepper motor 506 causes the drive block 504 to move horizontally, so that the spacer bar moves to the receiving ball 401. Then, the second cylinder is activated to move the slide plate 504a downward, so that the spherical joint 601 is placed inside the milled hemisphere 402. The spacer bar is moved to the receiving ball 401 of the finishing component 400. The control component drives the milling scraper 403 and the auxiliary scraper to finish the spherical joint 601 until the required dimensional accuracy and surface finish are achieved.

[0065] This equipment, through the coordinated operation of the bearing component 100, the milling component 200, and the finishing component 400, can achieve high-precision machining of the spherical joint 601 of the spacer bar, thereby improving machining efficiency and product quality.

[0068] The main body of the rod, 600, is long and strip-shaped, forged from 40Cr alloy structural steel. Its outer surface is heat-treated and its roughness is controlled below Ra1.6μm to ensure a smooth surface and reduce wear during use.

[0069] The main body of the rod 600 has spherical joints 601 integrally formed at both ends. The diameter of the spherical joints 601 is 1.2-1.5 times the diameter of the main body of the rod 600. The spherical surface is finely machined by CNC milling equipment, with a surface roughness ≤Ra0.8μm and uniform curvature, providing a smooth rotational basis for subsequent hinge connection.

[0070] Furthermore, the end connector 602 is made of ZG270-500 cast steel and then machined, possessing high structural strength and wear resistance. A connecting groove is opened on the end connector 602, the shape of which is adapted to the spherical surface of the ball joint 601, with a small gap reserved to reduce rotational friction. The inner surface of the groove is sprayed with a molybdenum disulfide wear-resistant coating to further reduce wear and extend service life.

[0071] Preferably, the end connector 602 is further provided with a first end plate 602a and a second end plate 602b, both of which are fan-shaped and symmetrically arranged.

[0072] Furthermore, a locking bolt 602c is installed between the first end plate 602a and the second end plate 602b. The bolt is an 8.8 grade high-strength bolt. Bolt holes are opened at corresponding positions on the first end plate 602a and the second end plate 602b. The diameter of the holes is 0.5mm larger than the diameter of the locking bolt 602c to facilitate the bolt insertion.

[0073] After clamping the cable, the operator can adjust the distance between the two end plates by tightening the locking bolt 602c, thereby adjusting the clamping force of the connecting groove on the ball joint 601. This ensures that the ball joint 601 can rotate flexibly and prevents the connection from becoming loose.

[0074] The first end plate 602a and the second end plate 602b also have grooves 603, which are rectangular or circular and extend through the thickness of the end plate.

[0075] The specific implementation principle of this embodiment is as follows: the ball joint 601 is embedded in the connecting groove of the end connector 602. By adjusting the tightness of the locking bolt 602c, the rotation damping of the ball joint 601 is controlled. When multi-angle adjustment is required, the ball joint 601 can rotate flexibly in the connecting groove to meet the connection requirements in different scenarios.
