A high-frequency fusion machine fusion size adjustment device

Abstract

This application relates to a fusion size adjustment device for a high-frequency fusion machine, belonging to the field of fusion machine technology. A first driving component enables the operation of first shifting parts on two support platforms, thereby causing two first laser units to move left and right. A second driving component enables the operation of second shifting parts on two support platforms, thereby causing two second laser units to move back and forth. By controlling the position of the lasers, size adjustment is achieved. A switching mechanism, with its third driving motor, causes a second rotating shaft to rotate, which in turn causes two fifth belts to rotate. As the fifth belts rotate, in conjunction with slide rails and sliders, one processing table can move left and right at the top, and the other processing table can move left and right at the bottom, thus achieving multi-station operation, saving time, and improving efficiency.

A second drive motor 706 is fixedly installed on one side of the top of the bottom support platform 3. A fourth pulley 707 is fixedly installed on the output shaft of the second drive motor 706, and a corresponding fourth pulley 707 is also fixedly installed on the second threaded rod 501. A fourth belt 708 is provided between the two fourth pulleys 707.

A fifth pulley 1106 is also rotatably connected to one side of the housing 12. A fifth belt is provided between the two fifth pulleys 1106 on the same side. The fifth belt 1107 is rotated by the rotation of the fifth pulley 1106. Connecting blocks 1108 are fixedly installed on both sides of the top and bottom ends of the fifth belt 1107. As the fifth belt 1107 rotates, the connecting blocks 1108, in conjunction with the fifth belt 1107, allow the two processing tables 10 to move. The bottom ends of the two connecting blocks 1108 located on the same side are fixedly connected to the top ends of the corresponding processing tables 10. The shifting mechanism 11 also includes a third drive motor 1109, which is fixedly mounted on one of the fixed motors via a motor mounting bracket.

The rotation of the output shaft of the third drive motor 1109 can drive the sixth pulley 1110 to rotate. A sixth pulley 1110 is also fixedly mounted on the second rotating shaft 1105. A sixth belt 1111 is provided between the two sixth pulleys 1110. As one sixth pulley 1110 rotates, it cooperates with the other sixth pulley 1110 to make the sixth belt 1111 rotate, thereby causing the second rotating shaft 1105 to rotate.

[0055] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, threaded posts are fixedly provided at the four corners of the bottom of the base 1, and foot cups are threadedly connected to the threaded posts.

[0056] Example 3:

[0057] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0058] Specifically, during operation / use of the high-frequency fusion machine's fusion size adjustment device: When adjusting the size, operate the first electronic handwheel group 13 to control the first drive motor 603. The output shaft of the first drive motor 603 drives the second pulley 604 to rotate. In conjunction with the second belt 605 and another second pulley 604, the corresponding first threaded rod 401 can rotate. As the first threaded rod 401 rotates, the corresponding first pulley 601 rotates. In conjunction with the first belt 602 and another first pulley 601, another first threaded rod 401 can rotate. With the rotation of both first threaded rods 401, two... A connector 403 drives the L-shaped plate 801 to move, thereby causing the two first lasers 802 to move relative to or in opposite directions. Operating the second electronic handwheel group 14 controls the second drive motor 706 to work. The output shaft of the second drive motor 706 drives the fourth pulley 707 to rotate. In conjunction with the fourth belt 708 and another fourth pulley 707, the corresponding second threaded rod 501 can rotate. This second threaded rod 501 can drive the corresponding universal joint coupling 701 to rotate, thereby causing the corresponding first rotating shaft 702 to rotate, which in turn causes the corresponding third pulley 704 to rotate. In conjunction with the third belt 705 and another third pulley 70... 4. This allows another first rotating shaft 702 to rotate, which in turn causes another second threaded rod 501 to rotate. As the second threaded rod 501 rotates, the corresponding connecting post 902 moves the second laser 903. Through the electric telescopic rod 904, the other connecting post 902 moves the other second laser 903, thus achieving dimensional adjustment. During processing, the two workpieces can be initially positioned at the top and bottom of the top processing table 10, respectively. After one workpiece is processed, the third drive motor 1109 is activated, and its output shaft drives the corresponding sixth pulley 1110. The rotation, in conjunction with the sixth belt 1111 and another sixth pulley 1110, causes the second rotating shaft 1105 to rotate. As the second rotating shaft 1105 rotates, the corresponding two fifth pulleys 1106 rotate. In conjunction with the other two fifth pulleys 1106, the two fifth belts 1107 rotate. As the fifth belts 1107 rotate, through the slide rail 1102 and the slider 1103, and in conjunction with the connecting block 1108, the two processing tables 10 can be moved. This allows one processed workpiece to be removed and placed on the workpiece to be processed while another workpiece is being processed, thus realizing multi-station operation, saving time, and improving efficiency.
