Detailed Implementation Methods

[0018] This invention provides a surface wire drawing processing apparatus, see [link to relevant documentation]. Figures 1 to 3 As shown, it includes a machine base 1, a rotating spindle 2 arranged vertically on the machine base 1, a wire drawing wheel 3 arranged at the rotating end of the rotating spindle 2, a first drive mechanism 4 arranged on the operating table of the machine base 1, and a positioning fixture 5 driven by the first drive mechanism 4; the positioning fixture 5 is used to position the material to be processed, and the positioning fixture 5 adjusts the position of the material to be processed under the drive of the first drive mechanism 4.

[0019] The surface drawing processing apparatus of this invention provides a vertical surface drawing processing apparatus for drawing the surface of materials by driving a drawing wheel 3 to rotate around a vertical axis via a vertically oriented rotating spindle 2 mounted on the machine base 1. This apparatus can replace the dedicated drawing machine used in the prior art, eliminating the need to purchase a dedicated machine and reducing equipment costs in production. The apparatus is also highly versatile; when drawing processing is not required and the apparatus is idle, the drawing wheel 3 can be replaced with other processing heads for other processing, avoiding equipment downtime and improving equipment utilization. The first driving mechanism 4 adjusts the position of the material to be processed from multiple angles, moving the material to a position suitable for the drawing wheel 3 to process, ensuring proper contact between the drawing wheel 3 and the surface of the material, guaranteeing the drawing effect, processing quality, and improved appearance of the drawn surface.

[0020] The first driving mechanism 4 includes a rotary driving component 41, a y-axis driving component 42 for driving the rotary driving component 41 to move along the y-axis direction, and an x-axis driving component 43 for driving the y-axis driving component 42 to move along the x-axis direction; the positioning fixture 5 is provided at the rotating end of the rotary driving component 41. In use, the positioning fixture 5, under the coordinated drive of the y-axis driving component 42, the x-axis driving component 43, and the rotary driving component 41, adjusts the position of the material to be processed at multiple angles by moving and rotating in the horizontal direction, so that the wire drawing wheel 3 on the rotating spindle 2 can make good contact with the surface of the material to be processed, thereby ensuring the processing quality of the wire drawing process and ensuring the processing effect of the material surface.

[0021] See Figure 4 and Figure 5 As shown, the positioning fixture 5 includes a fixture support 51 disposed along the y-axis at the rotating end of the rotary drive assembly 41, a vacuum adsorption platform 52 disposed at one end of the fixture support 51 away from the rotary drive assembly 41, and an ejection assembly 53 disposed within the fixture support 51 and having a telescopic end that can pass through the fixture support 51 and the vacuum adsorption platform 52; the ejection assembly 53 is used to eject the material to be processed from the vacuum adsorption platform 52. In use, the material to be processed is placed on the vacuum adsorption platform 52. The vacuum adsorption platform 52 adsorbs the material so that the first drive mechanism 4 can adjust the position of the material. After the wire drawing process is completed, the telescopic end of the ejector component 53 passes through the fixture bracket 51 and the vacuum adsorption platform 52 and ejects the material after the wire drawing process to unload the material. The ejector component 53 can unload the material without stopping the vacuum adsorption of the vacuum adsorption platform 52, which simplifies the structural settings for starting and stopping the vacuum of the vacuum adsorption platform 52 and the settings for the control program.

[0022] See Figure 6 As shown, the ejection assembly 53 includes a telescopic drive member 531 disposed in the fixture bracket 51 along the y-axis direction and a push rod 532 driven by the telescopic drive member 531; the fixture bracket 51 and the vacuum adsorption platform 52 are respectively provided with through holes 54 for the push rod 532 to pass through.

[0023] Furthermore, the push rod 532 has a limiting protrusion 533 arranged around its outer periphery on the side near the telescopic drive member 531. A limiting groove 521 is provided within the through hole 54 on the vacuum adsorption platform 52 to prevent the limiting protrusion 533 from passing through. The inner diameter of the limiting groove 521 is smaller than the outer diameter of the limiting protrusion 533. When the limiting protrusion 533 moves synchronously with the push rod 532, and the push rod 532 extends or retracts to a preset position, the limiting protrusion 533 moves to contact the limiting groove 521. Because the inner diameter of the limiting groove 521 is smaller than the outer diameter of the limiting protrusion 533, the limiting protrusion 533 is confined within the through hole 54 of the vacuum adsorption platform 52. The cooperation between the limiting protrusion 533 and the limiting groove 521 limits the extension and retraction of the push rod 532, ensuring that the push rod 532 can act on the material while preventing the push rod 532 from extending or retracting beyond its limit.

[0024] In some embodiments, the end of the push rod 532 away from the telescopic drive member 531 is provided with a contact portion 534, the outer diameter of which is larger than the outer diameter of the push rod 532; the vacuum adsorption platform 52 is provided with a recess 522 for embedding the contact portion 534. The provision of the contact portion 534 increases the contact area between the end of the push rod 532 and the material surface, avoiding the force concentration that could damage the material surface when the end of the push rod 532 applies force to the material surface. At the same time, the provision of the recess 522 allows the contact portion 534 to be embedded in the vacuum adsorption platform 52, ensuring the flatness of the vacuum adsorption platform 52.

[0025] Alternatively, in some other embodiments, a sensor for detecting whether the limiting protrusion 533 has moved into place may be provided in the limiting groove 521. The movement of the limiting protrusion 533 into place can trigger the sensor, and the sensor will feed back a detection signal to detect the position of the limiting protrusion 533.

[0026] Both the y-axis drive assembly 42 and the x-axis drive assembly 43 are linear guide rail drive mechanisms. Linear drive rails offer excellent operational stability, convenient installation, low maintenance costs, long service life, and high reliability; they ensure that the first drive mechanism 4 can operate with stable driving force while also saving on equipment manufacturing costs.

[0027] See Figures 1 to 3As shown, the surface wire drawing processing device further includes a lifting drive component 6. The rotating spindle 2 is mounted on the lifting drive component 6, which drives the rotating spindle 2 to move up and down along the z-axis. In use, the wire drawing wheel 3 moves up and down along the z-axis under the drive of the lifting drive component 6 and rotates around the z-axis under the drive of the rotating spindle 2. Through the cooperation between the lifting drive component 6 and the first drive mechanism 4, the position of the wire drawing wheel 3 and the position of the material to be processed are adjusted in a coordinated manner, ensuring that the wire drawing wheel 3 can make good contact with the surface of the material to be processed, further ensuring that the surface of the material after wire drawing has a better appearance and improving customer satisfaction.

[0028] In some embodiments, the machine base 1 is a CNC machining base, and the rotary spindle 2 is a spindle mounted on the CNC machining base. In use, the drive mechanism and the positioning fixture 5 are placed on the operating table of the CNC machining base 1, and the wire drawing wheel 3 is placed on the spindle of the CNC machining base to obtain the surface wire drawing processing device of the present invention. Then, a corresponding grinding path program is set according to the desired processing effect of the material to be processed. That is, the wire drawing processing device of the present invention can be obtained by structurally adjusting the CNC machine base of a CNC machining center. This allows for structural adjustments to the existing CNC machining center on the production line without the need to purchase a dedicated wire drawing machine, further reducing the cost of production equipment, lowering product production costs, and improving efficiency. By comparison, the equipment cost of the surface wire drawing processing device obtained using this solution is 1 / 3 of the cost of purchasing a dedicated wire drawing machine. Furthermore, during use, by changing the machining head mounted on the spindle of the CNC machining machine and switching to different machining processes, the device can perform both CNC machining and wire drawing, making it highly versatile and improving the utilization rate of equipment in the production line.

[0029] The above description is merely an embodiment of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
