Description
Technical Field
[0001] This utility model relates to the field of peripheral hole processing technology, and in particular to a workpiece peripheral hole processing equipment. Background Technology
[0002] In related technologies, when machining screen peripheral holes on workpieces with diameters ranging from 1.5m to 3m, the workpieces are large in diameter and long in length. When using existing four-axis machining centers to process them, the machining space within the four-axis machining center is relatively fixed, making it difficult to meet the processing needs of such workpieces. Manufacturing or purchasing additional four-axis machining centers capable of processing such workpieces is costly and increases the production costs of enterprises. Utility Model Content
[0003] The purpose of this utility model is to provide a workpiece peripheral hole processing equipment, which solves the problems of large size and high cost of existing equipment when processing peripheral holes of large diameter screens.
[0004] This utility model is implemented as follows: a workpiece peripheral hole processing device includes a first fixed structure, a second fixed structure, and a hole processing mechanism. The first fixed structure and the second fixed structure are arranged at intervals along the X direction. The first fixed structure and the second fixed structure are respectively used to limit the two ends of the workpiece and make the axis of the workpiece parallel to the X direction. The first fixed structure and / or the second fixed structure can drive the workpiece to rotate intermittently around its axis. The hole processing mechanism can reciprocate along the X direction and move along the Y direction to drill holes in the workpiece. The X direction is perpendicular to the Y direction.
[0005] To address the problems in the background technology, this application fixes both ends of the workpiece using a first fixed structure and a second fixed structure, respectively. During processing, the hole-making mechanism is adjusted in the X direction and then drills holes in the Y direction. The first fixed structure and / or the second fixed structure drive the workpiece to rotate intermittently, achieving circumferential drilling. The hole-making mechanism, moving in the X direction of the base, drills holes axially, thus completing the peripheral hole processing. The hole-making mechanism reciprocates in the X direction and drills holes in the Y direction, eliminating the complex beam structure of the hoisting method in existing technologies, reducing costs and the overall size of the peripheral hole processing equipment. Furthermore, the workpiece only needs intermittent circular motion, not linear movement. During peripheral hole processing, the rotation of the first fixed structure and / or the second fixed structure drives the workpiece to rotate, achieving circumferential drilling. The hole-making mechanism, moving in the X direction of the base, drills holes axially, thus completing the workpiece processing. This invention can also perform peripheral hole processing on workpieces with large diameters, long lengths, and heavy weights.
[0006] A further technical solution of this utility model is: the first fixing structure includes a chuck and a rotating mechanism for driving the chuck to rotate, wherein the chuck is used to clamp the workpiece.
[0007] After the workpiece is fixed on the chuck, it can be rotated by the rotary mechanism.
[0008] A further technical solution of this utility model is: the second fixing structure includes a cage, a roller and an adjusting member. The roller is placed inside the cage. The adjusting member is connected to the cage and one end is connected to the roller. The adjusting member is used to adjust the distance between the roller and the cage and to keep the rotation axis of the roller parallel to the X direction.
[0009] The workpiece is supported and can rotate by contacting the roller. When aligning the workpiece, the distance between the roller and the cage is adjusted by adjusting the adjustment component, thereby achieving the center adjustment of the roller on the workpiece and ensuring the accuracy of the workpiece during processing.
[0010] A further technical solution of this utility model is: the retainer includes an upper retainer and a lower retainer, and the upper retainer and the lower retainer are detachably connected.
[0011] Compared to limiting the workpiece from its end, the second fixing structure limits the workpiece from its outer periphery, resulting in higher stability. Moreover, during workpiece installation, the workpiece can be supported by the lower fixing part, and then limited by the upper fixing part in conjunction with the lower fixing part, making installation convenient.
[0012] A further technical solution of this utility model is: a lifting ring is detachably connected to the upper retainer.
[0013] A further technical solution of this utility model is: the hole processing mechanism includes a rotary processing head, a Y-direction driving structure is provided below the rotary processing head to drive the rotary processing head to reciprocate along the Y direction, an X-direction driving structure is provided below the Y-direction driving structure to drive the Y-direction driving structure to reciprocate along the X direction, and a base is provided below the X-direction driving structure.
[0014] For machining workpieces that are long, heavy, and large in diameter, the X-direction drive structure can drive the rotary machining head to perform machining sequentially along the length of the workpiece. The workpiece only needs to rotate and does not need to move linearly. When drilling holes in the workpiece, the rotary machining head is driven in the Y-direction to move along the Y-direction to achieve drilling. The rotary machining head, the Y-direction drive structure, and the X-direction drive structure are arranged sequentially from top to bottom to ensure the accuracy and stability of the machining.
[0015] A further technical solution of this utility model is: the rotary machining head includes a drill bit and a spindle motor, the spindle motor being used to drive the drill bit to rotate.
[0016] A further technical solution of this utility model is: the Y-direction drive structure includes a Y-axis servo motor and a second transmission component, the second transmission component is connected to the output end of the Y-axis servo motor, and the rotary processing head is connected to the second transmission component through a tray.
[0017] The Y-axis servo motor drives the second transmission component to move, causing the tray connected to the second transmission component to move linearly along the Y direction, with precise control and stable transmission.
[0018] A further technical solution of this utility model is: the X-direction drive structure includes an X-axis servo motor and a first transmission component. The output end of the X-axis servo motor is connected to the first transmission component. The first transmission component is connected to the Y-direction drive structure through a connecting seat. An X-axis guide rail is provided between the connecting seat and the base.
[0019] The Y-direction drive structure is placed on the connecting seat. The connecting seat and the base are provided with an X-direction drive structure and an X-axis guide rail. When the X-direction drive structure drives the Y-axis drive structure and the rotary machining head to move along the X-direction through the connecting seat, the X-axis guide rail can ensure the stability of the movement.
[0020] A further technical solution of this utility model is: the first fixing structure and the second fixing structure are coaxial along the X direction;
[0021] The workpiece peripheral hole processing equipment also includes a base extending along the X direction, and the second fixing structure is slidably connected to the base along the X direction.
[0022] The first and second fixing structures are coaxial along the X direction, ensuring that the workpiece fixed by the first and second fixing structures is parallel to the X direction; the second fixing structure slides along the X direction, which can accommodate workpieces of different lengths and is more convenient.
[0023] The beneficial effects of this utility model are as follows: This utility model fixes both ends of the workpiece using a first fixing structure and a second fixing structure, respectively. During processing, the hole-making mechanism is adjusted in the X direction and then drills holes in the Y direction. The first fixing structure and / or the second fixing structure drive the workpiece to rotate intermittently, achieving circumferential drilling. The hole-making mechanism, moving in the X direction of the base, achieves axial drilling, thus completing the peripheral hole processing. The hole-making mechanism reciprocates in the X direction and drills holes in the Y direction, eliminating the complex beam structure of the hoisting method in existing technologies, reducing costs and the overall size of the peripheral hole processing equipment. Furthermore, the workpiece only needs intermittent circular motion, not linear movement. During peripheral hole processing, the rotation of the first fixing structure and / or the second fixing structure drives the workpiece to rotate, achieving circumferential drilling. The hole-making mechanism, moving in the X direction of the base, achieves axial drilling, thus completing the workpiece processing. This utility model can also perform peripheral hole processing on workpieces with large diameters, long lengths, and heavy weights.
[0024] This utility model adopts a mechanism that separates the machine tool from the workpiece, which can process workpieces with larger diameters and heavier weights.
[0025] This invention adopts a numerical control programming method: the mechanical structure is simple and reliable, and the operation is convenient.
[0026] Compared with ordinary quadcopters, this utility model is cheaper, has a shorter manufacturing cycle, and is easier to maintain. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0032] Figure 1-3 A workpiece peripheral hole machining device is shown, including a first fixing structure, a second fixing structure, and a hole machining mechanism. The first fixing structure and the second fixing structure are arranged at intervals along the X direction.

[0037] In this embodiment, the adjusting member 9 is threadedly connected to the retainer 6, and the end of the adjusting member 9 is connected to the roller 8 through a bearing to ensure that the roller 8 will not rotate when the adjusting member 9 rotates.
[0038] In this embodiment, the workpiece 16 is placed inside the retainer 6, and is supported by rollers 8. When aligning the workpiece 16, the workpiece 16 can be adjusted to meet the drawing requirements by adjusting the jaws on the chuck 15 and the two adjusting parts 9 below the retainer 6.

The entire spindle and Y-axis drive system achieve X-axis feed motion through the X-axis servo motor 11 and its ball screw nut pair.

[0058] The working principle of this utility model:
[0059] The workpiece 16 is hoisted to the chuck 15 using a hoisting device, and then clamped and fixed to the gearbox 14 by the chuck 15. The cage 6 increases machining rigidity and is equipped with adjusting parts 9 and rollers 8 connected to them, which, together with the chuck 15, complete the workpiece alignment. In use: Loosen the connecting bolts 10, remove the upper fixing part 61 of the cage 6, install the workpiece 16 onto the machine tool, rotate the lower fixing part 62 of the cage 6, and use the two adjusting parts 9 to pre-support the workpiece 16. Then, reconnect the upper fixing part 61 of the cage 6 using the connecting bolts 10. During workpiece alignment: Simultaneously install dial indicators on the side of the workpiece 16 closest to the chuck 15 and the side of the cage 6. Jog the rotating mechanism and observe the changes in the dial indicator pointers. By adjusting the jaws on the chuck 15 and the two adjusting parts 9 below the cage 6, the workpiece 16 can be adjusted to meet the drawing requirements. After the workpiece is aligned, the peripheral hole machining begins: the hole machining mechanism first moves to the set position along the X direction, the rotary mechanism drives the workpiece 16 to perform indexing rotation positioning, the hole machining mechanism feeds along the Y direction, and works with the rotary machining head to drill holes in the workpiece 16, completing one drilling action; after completing one revolution of drilling, the hole machining mechanism moves to the next set position along the X direction and repeats the above drilling process until all peripheral holes of the workpiece 16 are machined. Depending on the drilling requirements of the workpiece 16, another peripheral hole machining method can also be selected: the hole machining mechanism moves along the X direction to drill holes in the workpiece 16 first, then the rotary mechanism drives the workpiece 16 to perform indexing rotation positioning, continuing to drill holes along the X direction until the workpiece 16 is machined.
[0060] In addition, the equipment can be configured with the 980TC3 optical system, which can be programmed for deep hole drilling modes according to different hole positions. Parts can be machined through tool setting and automatic machining. This expands its processing range, reduces production costs, and compared to ordinary four-axis machine tools, it is cheaper, can process larger diameters, has simpler programming operations, a simpler structure, and is easier to maintain.
