DETAILED DESCRIPTION

[0031] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] See also Figure 1-Figure 9 The present invention discloses a high-precision multi-station processing equipment, including a machine body, a processing drill bit and a supporting assembly. A turntable 40 and a turntable driving component are arranged on the machine body. A plurality of workpiece carriers 10 are arranged on the turntable 40. A processing knife assembly 30 is arranged above the turntable 40. The processing knife assembly 30 can process the workpiece on the workpiece carrier 10.

[0035] In addition, the support assembly includes a support base 21, a support slide 22 and a first driving member, the support slide 22 is installed on the support base 21, and the support slide 22 can move along a sliding direction, and a support plane is provided at the top of the support slide 22. The first driving member can drive the support slide to move along the sliding direction, so that the support plane approaches or moves away from the bottom end of the support workpiece carrier 10 to prevent the carrier from swinging up and down.

[0036] On the basis of the above structure, since the workpiece carrier 10 is rotatably mounted on the turntable of the machine body, when the workpiece is processed, the turntable can be driven to rotate by the turntable driving member on the machine body, so that the workpiece carrier 10 on the turntable is rotated to different processing stations for processing. A plurality of processing tool assemblies 30 are arranged on the rotation track of the turntable 40, so that each time the turntable 40 rotates to a station, a processing tool assembly 30 at a corresponding position processes the workpiece on the workpiece carrier 10, and the processing tool assembly 30 is set as a drill body 31 or a tool, and different drill body 31 sizes or models are set to perform different drilling actions on the workpiece. Milling operations on the workpiece can also be performed by different tools.

[0037] Of course, one processing knife assembly can also be provided, so that the workpiece carrier on the turntable is driven by the turntable driving member to rotate in sequence to the bottom of the processing knife assembly for sequential processing, thereby achieving uninterrupted and continuous processing of the workpiece and improving processing efficiency.

[0038] When the workpiece carrier 10 is rotated to the corresponding workstation, the processing tool of the processing equipment will process the workpiece on the workpiece carrier 10. Therefore, the force applied to the workpiece by the processing tool will cause the workpiece carrier 10 to shake or swing, etc., which will cause the workpiece on the workpiece carrier 10 to be unstable during the processing, thereby affecting the processing accuracy.

[0039] Therefore, in the present application, after the workpiece carrier 10 is rotated into place, the support slide 22 can be driven by the first driving member to slide along the support base 21, so that the support plane of the support slide 22 is abutted against the bottom end surface of the workpiece carrier 10, so that a larger support surface is formed at the bottom end of the workpiece carrier 10, thereby reducing the shaking or swinging of the workpiece carrier 10 during the processing. In this way, the workpiece can be stably supported during the processing, thereby improving the processing accuracy.

[0040] Furthermore, an inclined mounting surface is specifically provided at the top end of the support base 21, and the support slide 22 is slidably installed on the inclined mounting surface. At the same time, the first driving member is installed 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, and the sliding direction is consistent with the inclined mounting surface.

[0041] Based on this structure, the support slide 22 is driven to slide along the inclined direction by the power output end of the first driving member. The support plane of the support slide 22 is located at the top position of the support slide 22. After the support slide 22 slides and contacts the bottom end surface of the workpiece carrier 10, support can be achieved.

[0042] Since the driving force provided by the first driving member is inclined upward, the force in the inclined direction can drive the supporting slide 22 upward as well as forward. After the supporting plane of the supporting slide 22 abuts against the workpiece carrier 10, the forward force provided by the first driving member can remain applied to the side of the supporting slide 22, while the upward force provided by the first driving member can keep the supporting slide 22 upward, thereby effectively preventing the workpiece carrier 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 consistent with the inclined mounting surface, and the support slide 22 can be slidably installed on the inclined mounting plate 21132. The first driving member is installed on the inclined mounting plate 21132, so that the first driving member can drive the support slide 22 to slide along the inclined direction after driving the support slide 22 to move.

[0044] Specifically, the first driving member in this embodiment includes a driving cylinder 23, and 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 installed on the guide plate 212. Correspondingly, a guide hole is provided on the guide plate 212, and the piston rod 231 of the driving cylinder passes through the guide hole and extends along the inclined direction of the inclined mounting surface; the supporting slide 22 is connected to the piston rod 231 of the driving cylinder.

[0045] On the basis of this structure, when driving the support slide 22, the piston rod 231 of the driving cylinder is extended, driving the support slide 22 to move along the inclined mounting plate 21132. At the same time, the piston rod 231 of the driving cylinder passes through the guide hole. The guide hole can guide the piston rod 231 of the driving cylinder to slide along 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 driving cylinder 23, and thus the output supporting force of the piston rod is determined by the air pressure of the driving cylinder 23. Therefore, the air pressure of the driving cylinder 23 can be reasonably adjusted by the weight of the workpiece to be processed and the force applied to the workpiece carrier 10 by the processing intensity, so that the supporting force of the supporting slide 22 can be better maintained in balance.

[0047] Specifically, a first pressure sensor may be arranged on the top surface of the workpiece carrier 10, and a second pressure sensor may be arranged on the bottom surface of the workpiece carrier 10 accordingly. The first pressure sensor may detect the pressure applied to the workpiece carrier 10 when the workpiece carrier 10 is processed by a processing knife or the like. In order to make the forces applied to the workpiece carrier 10 equal and prevent the workpiece carrier 10 from shaking or swinging due to unbalanced forces applied to the upper and lower parts, the second pressure sensor may detect the pressure applied to the workpiece carrier 10 by the supporting slide 22 when the pressure value at the bottom is greater than or less than the pressure value at the top. The workpiece carrier 10 may shake. Therefore, the driving cylinder 23 may 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 balance the forces applied to the upper and lower parts.

[0048] Of course, the first driving member may also be a driving cylinder in the prior art, and the driving cylinder may also adjust the output force according to the pressure applied to the workpiece carrier 10 by the processing tool or the like during processing.

[0049] In addition, if the first driving member adopts the screw transmission structure in the prior art to drive the sliding, the output power of the screw is realized by the rotation of the thread. In this way, when the support slide 22 reaches the supporting position, if the supporting force is adjusted, the support slide 22 can only be driven to retreat or continue to press by the rotation of the screw. In this way, the support slide 22 will be separated from the workpiece carrier 10 or the workpiece carrier 10 will be directly pushed to swing upward, so that the workpiece carrier 10 will still swing. The first driving member that outputs power with fluid pressure, such as a driving cylinder 23 or a driving oil cylinder, can adjust the air pressure or hydraulic pressure while the support slide 22 maintains contact with the workpiece carrier 10, so that the support slide 22 can maintain a supporting state with the workpiece carrier 10 to adjust the supporting force, and will not cause the workpiece carrier 10 to swing.

[0050] Furthermore, a guide rail may 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 matched. In this way, when the support slide 22 moves along the inclined mounting plate 21132, the guide groove and the guide rail can be slidably matched to achieve the sliding guidance of the support slide 22, thereby preventing the support slide 22 from moving offset.

[0051] Furthermore, a supporting protrusion 221 is provided at the top of the supporting slide 22, and the top of the supporting protrusion 221 is formed as a supporting plane, so that when the supporting slide 22 moves toward the workpiece carrier 10 along the sliding direction, the bottom end of the workpiece carrier 10 can be planarly supported by the supporting plane at the top of the supporting protrusion 221.

[0052] In this way, by using the protruding support protrusion 221 for support, the first driving member does not need to drive the support slide 22 to move in the tilting direction too far, and the support protrusion 221 can contact the bottom end of the workpiece carrier 10 to achieve support.

[0053] Furthermore, the support protrusion 221 is connected to the support slide 22 through a support inclined surface. In this way, when the support protrusion 221 is subjected to a reaction force during processing on the workpiece carrier 10, the support inclined surface can be used to decompose the longitudinal force into a lateral force, thereby reducing the longitudinal force directly applied to the support slide 22, thereby effectively preventing the support slide 22 from retreating along the sliding direction, and making the support process smoother.

[0054] Furthermore, a positioning component is provided on the workpiece carrier 10, and the positioning component is used to position the workpiece.

[0055] Furthermore, the positioning assembly includes multiple first positioning blocks 11 and multiple second positioning blocks 12; the top end surfaces of the multiple first positioning blocks 11 together form a first positioning surface; the top end surfaces of the multiple second positioning blocks 12 together form a second positioning surface; the multiple first positioning blocks 11 are distributed on both sides of the multiple 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 carrier 10, since the heights of the multiple first positioning blocks 11 and the multiple second positioning blocks 12 are different, the first positioning surfaces formed by the multiple first positioning blocks 11 and the second positioning surfaces formed by the multiple second positioning blocks 12 are at different positions on the workpiece carrier 10. When placing the workpiece, the first positioning surfaces and the second positioning surfaces can abut against different end surfaces of the workpiece, so that 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. In this way, when the middle position of the workpiece is relatively high and the positions on both sides are relatively low, the workpiece is placed on the workpiece carrier 10, and the higher second positioning surface is used for positioning and abutting at the middle high position, while the lower first positioning surface can be used for positioning and abutting at the low positions on both sides, and the positioning structure is stable.

[0058] Of course, the height of the second positioning block 12 can also be set to be smaller than the height of the first positioning block 11, so that it can be adapted to a workpiece with a low middle position and relatively high positions on both sides. The specific selection is made according to actual needs.

[0059] Furthermore, the processing tool assembly 30 includes a second driving member, a mounting frame 34, a plurality of processing drill bits and a third driving member, and the second driving member and the mounting frame 34 are both mounted on the machine body. The plurality of processing drill bits can be rotatably mounted on the mounting frame 34, and specifically, the second driving member can drive the mounting frame 34 to move up and down along the height direction of the machine body. After the mounting frame 34 moves downward driven by the second driving member, the plurality of processing drill bits on the mounting frame 34 can contact the workpiece on the workpiece carrier 10, and driven by the third driving member, the processing drill bits rotate to perform drilling operations on the workpiece.

[0060] After the processing is completed, the second driving member drives the mounting frame 34 upward, and the processing drill bit can be withdrawn from the workpiece to prepare for the next processing.

[0061] More specifically, the above-mentioned processing tool assembly 30 also includes a mounting plate 32, the processing drill bit includes a first connecting head 311, a linkage rod 33 and a drill bit body 31, a second connecting head 341 is provided at the top of the drill bit body 31, and the first connecting head 311 is rotatably installed on the mounting frame 34, one end of the linkage rod 33 is detachably connected to the first connecting head 311, and the other end of the linkage rod 33 is detachably connected to the second connecting head 341, the drill bit body 31 is fixed to the bottom end of multiple processing drill bits, and the above-mentioned second connecting head 341 can be rotatably installed on the mounting plate 32, and the second connecting head 341 is detachably connected to the mounting plate 32.

[0062] On the basis of this structure, a plug-in block can be provided on the first connector 311, and a first plug-in slot is provided at one end of the linkage rod 33, so that the first connector 311 and the linkage rod 33 can be inserted into the first plug-in slot through the plug-in block, and then connected by bolts or screws. A second plug-in slot is provided at the other end of the linkage rod 33, and a plug-in block is provided at the second connector 341, so that the second connector 341 can also be inserted into the second plug-in slot through the plug-in block, and then connected by bolts or screws, etc., so that it is convenient to disassemble and assemble the multiple drill body 31 on the mounting plate 32, and it is convenient to overhaul and replace the size or model of the drill body 31.

[0063] It should be noted that the above-mentioned turntable drive member and the third drive member can be selected as a motor in the prior art, or a motor with a belt transmission structure or a gear transmission structure to achieve drive, so that the power output is stable. The second drive member can be selected as a drive cylinder or a drive oil cylinder in the prior art, or a power output structure such as a screw transmission structure, which can be selected according to actual needs.
