Detailed Implementation

[0031] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0034] See Figures 1-9 The present invention discloses a high-precision multi-station machining equipment, including a machine body, a machining drill bit and a support assembly. The machine body is provided with a turntable 40 and a turntable drive component. Multiple workpiece platforms 10 are provided on the turntable 40. A machining tool assembly 30 is located above the turntable 40. The machining tool assembly 30 can process the workpieces on the workpiece platforms 10.

[0035] Additionally, the support assembly includes a support base 21 and a support slide 22. A first driving member mounts the support slide 22 onto the support base 21, and the support slide 22 is movable in a sliding direction. A support plane is provided at the top of the support slide 22. The aforementioned first driving member can drive the support slide to move in the sliding direction, so that the support plane approaches or moves away from the bottom end of the workpiece platform 10, thereby preventing the workpiece platform from swinging up and down.

[0036] Based on the above structure, since the workpiece stage 10 is rotatably mounted on the turntable of the machine body, during workpiece processing, the turntable can be driven to rotate by the turntable drive component on the machine body. This allows the workpiece stage 10 on the turntable to rotate to different processing positions for processing. Multiple machining tool assemblies 30 are arranged along the rotation trajectory of the turntable 40. Thus, each time the turntable 40 rotates to a different position, a corresponding machining tool assembly 30 processes the workpiece on the workpiece stage 10. The machining tool assembly 30 is configured as a drill bit body 31 or a cutting tool. Different drill bit body 31 sizes or models allow for different drilling operations on the workpiece. Milling operations can also be performed on the workpiece using different cutting tools.

[0037] Of course, a machining tool assembly can also be set up. In this way, the workpiece platform on the turntable is driven by the turntable drive to rotate sequentially to the bottom of the machining tool assembly for sequential processing, so as to realize uninterrupted continuous processing of the workpiece and improve processing efficiency.

[0038] When the workpiece platform 10 rotates to the corresponding station, the machining tool of the machining equipment will process the workpiece on the workpiece platform 10. Therefore, the force applied to the workpiece by the machining tool and the like will cause the workpiece platform 10 to shake or swing. This will cause the workpiece on the workpiece platform 10 to be unstable during the processing, thus affecting the machining accuracy.

[0039] Therefore, in this application, after the workpiece stage 10 is rotated into position, the first driving member can drive the support slide 22 to slide along the support base 21 so that the support plane of the support slide 22 abuts against the bottom surface of the workpiece stage 10, so that the plane forms a large support surface at the bottom of the workpiece stage 10, thereby reducing the shaking or swaying of the workpiece stage 10 during the processing. In this way, the workpiece can be stably supported during the processing, thereby improving the processing accuracy.

[0040] Furthermore, specifically, an inclined mounting surface is provided at the top of the support base 21, and the support slide 22 is slidably mounted on the inclined mounting surface. At the same time, the first driving member is mounted on the inclined mounting surface so that the power output end of the first driving member extends along the inclined mounting surface and drives the support slide 22 to slide along the inclined mounting surface in the same direction as the inclined mounting surface.

[0041] Based on this structure, the power output end of the first driving member drives the support slide 22 to slide in the inclined direction. The support plane of the support slide 22 is located at the top of the support slide 22. After the support slide 22 slides and contacts the bottom surface of the workpiece platform 10, it can achieve support.

[0042] Since the driving force provided by the first driving member is inclined upward, the force in the inclined direction can drive the support slide 22 upward and forward at the same time. After the support plane of the support slide 22 abuts against the workpiece platform 10, the forward force provided by the first driving member can be applied to the side of the support slide 22, while the upward force provided by the first driving member can keep the support slide 22 upward. This can effectively prevent the workpiece platform 10 from retreating after being subjected to force.

[0043] More specifically, in order to enable the first driving member and the support slide 22 to be installed in an inclined state, an inclined mounting plate 21132 can be provided on the inclined mounting surface. The inclined mounting plate 21132 is aligned with the inclined mounting surface. The support slide 22 is slidably mounted on the inclined mounting plate 21132. The first driving member is mounted on the inclined mounting plate 21132. In this way, after the first driving member drives the support slide 22 to move, it can drive the support slide 22 to slide along the inclined direction.

[0044] Specifically, in this embodiment, the first driving component includes a driving cylinder 23. A guide plate 212 is provided at the end of the inclined mounting plate 21132, and the cylinder body of the driving cylinder 23 is mounted on the guide plate 212. A guide hole is provided on the guide plate 212, through which the piston rod 231 of the driving cylinder passes and extends along the inclined direction of the inclined mounting surface; the support slide 22 is connected to the piston rod 231 of the driving cylinder.

[0045] Based on this structure, when driving the support slide 22, the piston rod 231 of the drive cylinder extends and drives the support slide 22 to move along the inclined mounting plate 21132. At the same time, the piston rod 231 of the drive cylinder passes through the guide hole, which can guide the piston rod 231 of the drive cylinder to slide in the inclined direction, so that the movement direction of the support slide 22 is more stable.

[0046] Of course, in this embodiment, the piston rod is extended by the output air pressure of the drive cylinder 23. Therefore, the output support force of the piston rod is determined by the air pressure of the drive cylinder 23. Thus, the air pressure of the drive cylinder 23 can be reasonably adjusted by the force applied to the workpiece platform 10 by the weight of the workpiece and the processing intensity, so that the support force of the support slide 22 can be better maintained in balance.

[0047] Specifically, a first pressure sensor can be installed on the top surface of the workpiece stage 10, and a second pressure sensor can be installed on the bottom surface of the workpiece stage 10. The first pressure sensor detects the pressure applied to the workpiece stage 10 when it is being processed by a machining tool. In order to ensure that the workpiece stage 10 is subjected to the same force from top to bottom and to prevent the workpiece stage 10 from shaking or swaying due to uneven force from top to bottom, the second pressure sensor detects the pressure on the workpiece stage 10 supported by the lifting support of the support slide 22. When the pressure value below is greater than or less than the pressure value above, it will cause the workpiece stage 10 to shake. Therefore, the drive cylinder 23 can adjust the air pressure according to the pressure value provided by the second pressure sensor and the pressure value provided by the first pressure sensor to make the force from top to bottom balanced.

[0048] Of course, the first driving component can also be a driving cylinder in the prior art. Similarly, the output force of the driving cylinder can be adjusted according to the pressure applied to the workpiece platform 10 during processing by the machining tool, etc.

[0049] Furthermore, if the first driving component uses a screw drive structure as in the prior art to drive the sliding, the output power of the screw is achieved by screw rotation. In this case, when the support slide 22 reaches the support position, if the support force is adjusted, the only way is to rotate the screw to drive the support slide 22 to retract or continue to press. This would cause the support slide 22 to separate from the workpiece platform 10 or directly push the workpiece platform 10 to swing upwards, resulting in the workpiece platform 10 still swinging. However, if the first driving component, such as the drive cylinder 23 or the drive cylinder, outputs power with fluid pressure, it can adjust the air pressure or hydraulic pressure while the support slide 22 is in contact with the workpiece platform 10. This allows the support slide 22 to maintain a supported state with the workpiece platform 10 and adjust the support force without causing the workpiece platform 10 to swing.

[0050] Furthermore, a guide rail can be provided on the inclined mounting plate 21132, and the guide rail extends along the inclined direction of the inclined mounting surface. Correspondingly, a guide groove is provided at the bottom end of the support slide 22; the guide rail and the guide groove are slidably engaged. In this way, when the support slide 22 moves along the inclined mounting plate 21132, the sliding engagement between the guide groove and the guide rail can realize the sliding guidance of the support slide 22 and prevent the support slide 22 from deviating from its movement.

[0051] Furthermore, the top of the support slide 22 is provided with a support protrusion 221, and the top of the support protrusion 221 is formed as a support plane. In this way, when the support slide 22 moves toward the workpiece stage 10 along the sliding direction, the support plane at the top of the support protrusion 221 can provide planar support for the bottom end of the workpiece stage 10.

[0052] With the support provided by the protruding support bump 221, the first driving member does not need to travel too far to move the support slide 22 in the inclined direction. The support bump 221 can then contact the bottom end of the workpiece platform 10 to achieve support.

[0053] Furthermore, the support protrusion 221 is connected to the support slide 22 by the support inclined surface. When the support protrusion 221 is subjected to the reaction force during processing on the workpiece platform 10, the longitudinal force can be decomposed into the transverse force by the support inclined surface, reducing the longitudinal force directly applied to the support slide 22. This can effectively prevent the support slide 22 from retracting along the sliding direction, making the support process more stable.

[0054] Furthermore, the workpiece stage 10 is equipped with a positioning component, which is used to position the workpiece.

[0055] Furthermore, the positioning component includes a plurality of first positioning blocks 11 and a plurality of second positioning blocks 12; the top surfaces of the plurality of first positioning blocks 11 together form a first positioning surface; the top surfaces of the plurality of second positioning blocks 12 together form a second positioning surface; the plurality of first positioning blocks 11 are distributed on both sides of the plurality of second positioning blocks 12; the first positioning blocks 11 and the second positioning blocks 12 have different heights.

[0056] Based on this structure, after the workpiece is placed on the workpiece platform 10, since the heights of the multiple first positioning blocks 11 and the multiple second positioning blocks 12 are different, the positions of the first positioning surface formed by the multiple first positioning blocks 11 and the second positioning surface formed by the multiple second positioning blocks 12 on the workpiece platform 10 are different. When placing the workpiece, the first positioning surface and the second positioning surface can abut against different end faces of the workpiece, so the positioning structure is more stable.

[0057] In this embodiment, the height of the second positioning block 12 is greater than the height of the first positioning block 11. When the middle position of the workpiece is relatively high and the two sides are relatively low, the workpiece is placed on the workpiece platform 10. The higher second positioning surface is positioned and abutted in the middle high position, while the lower first positioning surface can be positioned and abutted in the lower positions on both sides, making the positioning structure stable.

[0058] Of course, the height of the second positioning block 12 can also be set to be less than the height of the first positioning block 11. This can be adapted to workpieces with a low middle position and relatively high sides. The specific choice depends on the actual needs.

[0059] Furthermore, the aforementioned machining tool assembly 30 includes a second drive member, a mounting bracket 34, multiple machining drill bits, and a third drive member. Both the second drive member and the mounting bracket 34 are mounted on the machine body. The multiple machining drill bits are rotatably mounted on the mounting bracket 34. Specifically, the second drive member can drive the mounting bracket 34 to move up and down along the height direction of the machine body. After the mounting bracket 34 moves downward under the drive of the second drive member, the multiple machining drill bits on the mounting bracket 34 can contact the workpiece on the workpiece platform 10, and under the drive of the third drive member, the machining drill bits rotate to perform drilling operations on the workpiece.

[0060] After processing is completed, the second drive unit drives the mounting bracket 34 upward, allowing the machining drill bit to exit the workpiece and prepare for the next processing.

[0061] More specifically, the aforementioned machining tool assembly 30 also includes a mounting plate 32. The machining drill bit includes a first connector 311, a linkage rod 33, and a drill bit body 31. A second connector 341 is provided at the top of the drill bit body 31. The first connector 311 is rotatably mounted on the mounting bracket 34. One end of the linkage rod 33 is detachably connected to the first connector 311, and the other end of the linkage rod 33 is detachably connected to the second connector 341. The drill bit body 31 is fixed to the bottom end of multiple machining drill bits. The aforementioned second connectors 341 are all rotatably mounted on the mounting plate 32, and the second connectors 341 are detachably connected to the mounting plate 32.

[0062] Based on this structure, an insert block can be provided on the first connector 311, and a first insert groove is provided at one end of the linkage rod 33. In this way, the first connector 311 and the linkage rod 33 can be inserted into the first insert groove through the insert block, and then connected by bolts or screws. The other end of the linkage rod 33 is provided with a second insert groove, and the second connector 341 is provided with an insert block. In this way, the second connector 341 can also be inserted into the second insert groove through the insert block, and then connected by bolts or screws. This facilitates the disassembly and assembly of multiple drill bit bodies 31 on the mounting plate 32, and makes it convenient for maintenance and replacement of the size or model of the drill bit body 31.

[0063] It should be noted that the aforementioned turntable drive component and the third drive component can be selected from existing technologies, such as motors, or a motor combined with a belt drive structure or a gear drive structure to achieve stable power output. The second drive component can be selected from existing technologies, such as drive cylinders or drive hydraulic cylinders, or a power output structure such as a lead screw drive structure, depending on the actual needs.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
