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.

[0044] The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0045] A multifunctional high-precision mechanical parts processing device, comprising a rotating device table 1 and a parts clamping mechanism 2 uniformly distributed around the end surface thereof, a parts processing mechanism 3 corresponding to the parts clamping mechanism 2 is arranged around the circumference of the device table 1, and the parts processing mechanism 3 is aligned with the parts on the parts clamping mechanism 2 through a docking positioning mechanism;

[0046] In the prior art, parts need to be drilled, reamed, and bored during processing.

[0047] However, the processing equipment currently on the market can only perform a single process of the above process on the parts, and then perform other processes, so the processing efficiency is low; in addition, the existing equipment cannot perform mechanical

[0048] It is difficult to meet the market and mechanical parts finishing requirements for precise positioning and processing of parts; therefore, in this embodiment, the positioning mechanism is firstly connected to the part processing mechanism 3 to align the part processing mechanism 3 with the part on the part clamping mechanism 2; when the alignment is completed, since the device table 1 is designed to be rotatable, its rotation angle is 360 degrees divided by the number of corresponding part processing mechanisms 3. In this embodiment, a dividing plate for controlling the rotation angle is installed under the device table 1, and eight part processing mechanisms 3 are used, so the single rotation angle of the device table 1 is 45 degrees, and the output end of the spindle 8 on the part processing mechanism 3 can replace different parts Cutting tools, such as drills, reamers, boring tools, etc., so in this embodiment, eight parts processing mechanisms 3 are installed with different parts cutting tools. When the device table 1 rotates to the first part processing mechanism, the processing mechanism 3 performs the first processing on the part clamped on the part clamping mechanism 2. When the device table 1 rotates 45 degrees, the part is driven by the second part processing mechanism, and the second part processing mechanism performs the second processing on the part. The following steps are carried out in sequence according to the above processing flow. When the part rotates one circle, the part processing is completed and the part is removed. In this embodiment, a dividing plate for controlling the rotation angle is installed under the device table 1. In addition, considering the convenience of taking and placing parts, in this embodiment, a position of a part processing mechanism 3 is reserved that does not participate in part processing. When the device table 1 drives the part to rotate to the position of the part processing mechanism 3, the processed part is removed and replaced with a new unprocessed part.

[0049] The output end of the spindle 8 of the part processing mechanism 3 is connected with a detachable part processing cutter head;

[0050] The positioning mechanism comprises a positioning plate 1-1 fixedly mounted on the device table 1, the positioning plate 1-1 and the part clamping mechanism 2 are in the same horizontal plane, a plurality of tubular docking devices 1-2 are evenly distributed on the positioning plate 1-1, and a docking head 3-1 matching the docking devices 1-2 is installed on the part processing mechanism 3;

[0051] In this embodiment, two docking devices 1 - 2 are provided. When the docking device 1 - 2 is completely docked with the docking head 3 - 1 , the docking positioning mechanism is aligned with the parts on the part clamping mechanism 2 .

[0052] The part processing mechanism 3 includes a front and rear docking assembly that drives the docking joint 3-1 to move back and forth along the docking device 1-2, and the front and rear docking assembly is equipped with a left and right alignment assembly that drives the docking joint 3-1 to move left and right along the docking device 1-2, and the left and right alignment assembly is equipped with a rotation alignment assembly that drives the docking joint 3-1 to rotate along the docking device 1-2;

[0053] The purpose of this design is: since there may be an offset between the rotation angle of the device table 1 and the placement position of the part processing mechanism 3, the docking of the docking connector 1-2 and the docking joint 3-1 is not just a vertical straight line docking, but also requires horizontal left and right adjustment. However, if there is only left and right adjustment, it is likely that one docking joint 3-1 corresponds to the docking connector 1-2, and there is a gap between the other docking joint 3-1 and the docking connector 1-2. Therefore, rotation adjustment is also required at this time so that the end faces of the two docking joints 3-1 can completely correspond to the docking connector 1-2, so that the docking joint 3-1 can be completely docked with the docking connector 1-2.

[0054] The front and rear docking assembly includes a plurality of guide columns 4 installed in the vertical direction of the docking device 1-2 and a first carrier plate 5 slidably installed on the guide columns 4; in this embodiment, two guide columns 4 are provided, and the first carrier plate 5 is slidably set on the guide columns 4 through sliders 5-2 evenly distributed at its four corners, and also includes a driving cylinder, and the output end of the driving cylinder 11 is fixedly connected to the first carrier plate 5.

[0055] The left and right alignment components include a plurality of slide rails 5-1 installed in the horizontal direction of the docking device 1-2 and a second carrier plate 6 slidably installed on the slide rails 5-1. The slide rails 5-1 are integrally formed with the first carrier plate 5. In this embodiment, two slide rails 5-1 are provided, and the second carrier plate 6 slides in the horizontal direction of the docking device 1-2.

[0056] The rotation alignment assembly includes a third carrier plate 7 that rotates along the docking device 1-2, and the third carrier plate 7 is rotatably connected to the second carrier plate 6 through a bearing. The third carrier plate 7 is an L structure, and the docking joint 3-1 is installed at one end of the third carrier plate close to the docking device 1-2; in this embodiment, the third carrier plate 7 and the second carrier plate 6 are rotatably connected using a slewing bearing 14, the inner ring disk of the slewing bearing 14 is fixedly connected to the second carrier plate 6, and the outer ring disk of the slewing bearing 14 is fixedly connected to the third carrier plate 7.

[0057] It also includes a left and right reset assembly and a rotation reset assembly. The left and right reset assembly includes a reset cylinder I6-1 arranged at the end of the second carrier plate 6, and the output end of the reset cylinder I6-1 conflicts with the end of the slide rail 5-1; the rotation reset assembly includes a reset cylinder arranged at the end of the third carrier plate 7.

[0058] II7-1, the output end of the reset cylinder II7-1 conflicts with the end of the third carrier plate 7;

[0059] When the second carrier plate 6 and the third carrier plate 7 complete the alignment, the second carrier plate 6 may move left and right, and the third carrier plate 7 may rotate. When the next alignment is performed, a reset device is required to restore the second carrier plate 6 and the third carrier plate 7 to a position flush with the first carrier plate 5, that is, to align the second carrier plate 6 and the third carrier plate 7. In this embodiment, two reset cylinders I6-1 are provided. When the second carrier plate 6 needs to be reset, the output ends of the two reset cylinders I6-1 respectively contact the slide rail 5-1.

[0060] At both ends, restore the second carrier plate 6 to a position flush with the first carrier plate 5;

[0061] Two reset cylinders II7 - 1 are provided. When the third carrier plate 7 needs to be reset, the output ends of the two reset cylinders II7 - 1 respectively contact the two ends of the third carrier plate 7 to restore the third carrier plate 7 to a position flush with the first carrier plate 5 .

[0062] A linear guide 7-2 and a spindle 8 sliding on the linear guide 7-2 are installed on the third carrier plate 7. One end of the spindle 8 is connected to a pulley motor 13 through a belt. The pulley motor 13 drives the spindle 8 to rotate, and the spindle 8 moves along the part clamping mechanism 2 through a ball screw assembly. In this embodiment, the ball screw assembly includes a ball screw 7-3 and a ball screw nut. Both ends of the ball screw 7-3 are rotatably mounted on a screw mounting seat through bearings. One side of the ball screw 7-3 engages with a gear at the output end of the drive motor 12, and the ball screw nut is fixedly connected to the bottom surface of the spindle 8.

[0063] The part clamping mechanism 2 includes an upper jaw 2-1 and a lower jaw 2-2 which move synchronously toward each other to clamp the part, and limit grooves are provided on the upper jaw 2-1 and the lower jaw 2-2, and the part is mounted in the limit grooves; the purpose of this design is: since in the part processing of this embodiment, it is necessary to process at the center position of the part, when the part needs to be clamped, the upper jaw 2-1 and the lower jaw 2-2 move synchronously toward each other until the part is clamped, at which time the part is at the center position between the upper jaw 2-1 and the lower jaw 2-2, and the center distances from the part to the upper jaw 2-1 and the lower jaw 2-2 are the same, even if other parts with different thicknesses and heights are replaced, when the part is clamped, the part is still at the center position between the upper jaw 2-1 and the lower jaw 2-2, and the center distances from the part to the upper jaw 2-1 and the lower jaw 2-2 are still the same, and the output end of the spindle 8 is still aligned with the center position of the part.

[0064] The part clamping mechanism 2 also includes a bidirectional lead screw, on which a first nut and a second nut are installed that move synchronously toward each other, one end of the upper clamping jaw 2-1 is fixedly connected to the first nut, and one end of the lower clamping jaw 2-2 is fixedly connected to the second nut;

[0065] In this embodiment, for the safety of equipment use, a protective shell 2-3 is installed outside the bidirectional screw. Both ends of the bidirectional screw are rotatably installed in the protective shell 2-3 through bearings, and one side of the bidirectional screw is meshed with the gear II at the output end of the drive motor II.

[0066] The device table 1 is also provided with a chute 9 for collecting waste, the bottom of the chute 9 is provided with an opening 9-1, one side of the opening 9-1 is provided with a stopper 9-2 for preventing the waste from rotating, and a waste conveying device is placed below the opening 9-1; the waste conveying device includes a collecting box 10, one side of the collecting box 10 is provided with a support rod 10-2, one end of the support rod 10-2 is fixedly connected to the stopper 9-2; a conveying pipe 10-1 is installed in the collecting box 10, a plurality of scrapers are installed in the conveying pipe 10-1, and the scrapers and the inner wall of the conveying pipe 10-1 form a material transport cavity One end of the scraper is connected to a chain that drives the scraper to circulate in the conveying pipe 10-1. One end of the conveying pipe 10-1 extends into the collecting box 10, and the other end is connected to the waste transportation device; the conveying pipe 10-1 is two conveying pipes connected side by side, which are divided into a return pipe 10-1-1 and a material transport pipe 10-1-2. A rotating motor is installed at the end connection of the return pipe 10-1-1 and the material transport pipe 10-1-2. The output end of the rotating motor is connected to the rotating shaft 10-1-3. A gear III is fixedly mounted on the rotating shaft 10-1-3, and the chain is meshed with the gear III.

[0067] Since the device table 1 is constantly rotating, the waste in the chute 9 rotates synchronously with the device table 1. When the waste hits the block 9-2 during the rotation, the waste on the side of the block 9-2 stops moving and accumulates on the side of the block 9-2. When the opening 9-1 moves to a position close to the block 9-2, the waste accumulated on the side of the block 9-2 enters the collection box 10 from the opening 9-1. The inner bottom of the collection box 10 is an inclined structure. The waste moves to the end of the conveying pipe 10-1 under the action of gravity. The scraper is driven by the chain to bring the waste into the conveying pipe 10-1 and convey it to the waste transport device through the conveying pipe 10-1.

[0068] In this embodiment, the waste transport device is a waste storage box with universal wheels.

[0069] A control process for a multifunctional high-precision mechanical parts processing device, comprising:

[0070] In the first step, the left and right reset components and the rotation reset component are turned on;

[0071] The output end of the reset cylinder I6-1 conflicts with the end of the slide rail 5-1; the rotary reset assembly includes a reset cylinder II7-1 disposed at the end of the third carrier plate 7, and the output end of the reset cylinder II7-1 conflicts with the end of the third carrier plate 7 to prevent the second carrier plate 5 and the third carrier plate 7 from shaking when moving along the docking device 1-2, driving the docking joint 3-1 to shake, causing the docking joint 3-1 to deviate too much and be unable to dock with the docking device 1-2;

[0072] In the second step, the first carrier plate 5 drives the docking joint 3-1 to move along the direction of the docking device 1-2; the output end of the driving cylinder 11 is opened, driving the first carrier plate 5 to slide on the guide column 4, so that the docking joint 3-1 is docked with the docking device 1-2;

[0073] In the third step, the docking joint 3-1 is connected to the docking device 1-2, the left and right reset components are opened and the rotation reset component is closed; when the docking joint 3-1 contacts the front end of the docking device 1-2, the output ends of the reset cylinder I6-1 and the reset cylinder II7-1 retract, and the left and right movement of the second carrier plate 6 and the rotation movement of the third carrier plate 7 are not restricted. If the docking joint 3-1 and the docking device 1-2 are not aligned with the same axis, there will be a gap between the docking joint 3-1 and the docking device 1-2. Since the driving cylinder 11 continuously drives the first carrier plate 5 to move, the docking joint 3-1 will contact the side wall of the docking device 1-2, and the second carrier plate 6 will not be restricted. Plate 6 moves left and right, and the third carrier plate 7 rotates until the docking joint 3-1 is completely docked with the docking device 1-2, that is, the docking joint 3-1 and the docking device 1-2 are coaxial; in the fourth step, the docking joint 3-1 and the docking device 1-2 are docked, the first carrier plate 5 stops moving, and the ball screw assembly drives the spindle 8 to move along the direction of the part and processes the part; in the fifth step, the single part processing is completed, the first carrier plate 5 drives the docking joint 3-1 to move away from the docking device 1-2 and repeats the first step; in the sixth step, the device table 1 drives the part to be transferred to the next part processing mechanism and then stops rotating, and repeats the first to fifth steps.

[0074] Working principle:

[0075] Alignment before machining parts:

[0076] When the docking joint 3-1 on the part processing mechanism 3 is docked with the docking device 1-2 on the device table 1, the first carrier plate 5, driven by the driving cylinder 11, drives the docking joint 3-1 in the vertical direction to linearly dock the docking device 1-2. When the front end of the docking joint 3-1 enters the docking device 1-2, the output ends of the reset cylinder I6-1 and the reset cylinder II7-1 retract. Since the rotation angle of the device table 1 and the placement position of the part processing mechanism 3 may be offset, if the docking joint 3-1 and the docking device 1-2 are not In the same vertical plane, there is a gap between the docking joint 3-1 and the docking device 1-2. Since the driving cylinder 11 continuously drives the first carrier plate 5 to move, the docking joint 3-1 will contact the side wall of the docking device 1-2, the second carrier plate 6 moves left and right, and the third carrier plate 7 rotates until the docking joint 3-1 is completely docked with the docking device 1-2, that is, the docking joint 3-1 and the docking device 1-2 are coaxial. At this time, the spindle 8 moves toward the part clamping mechanism 2 through the ball screw assembly to process the parts on the part clamping mechanism 2;

[0077] When machining parts:

[0078] Since the device table 1 is designed to be rotatable, its rotation angle is 360 degrees divided by the number of corresponding part processing mechanisms 3. In this embodiment, eight part processing mechanisms 3 are used, so the single rotation angle of the device table 1 is 45 degrees. The output end of the spindle 8 on the part processing mechanism 3 can replace different part cutting tools, such as drill bits, reamers, boring tools, etc. Therefore, in this embodiment, the eight part processing mechanisms 3 are installed with different part cutting tools. When the device table 1 rotates to the first part processing mechanism, the processing mechanism 3 performs the first processing on the part clamped on the part clamping mechanism 2. When the device table 1 rotates 45 degrees, the part is driven by the second part processing mechanism, and the second part processing mechanism performs the second processing on the part. The subsequent steps are performed in sequence according to the above processing flow. When the part rotates one circle, the part processing is completed and the part is removed. In this embodiment, a dividing plate for controlling the rotation angle is installed under the device table 1.

[0079] In addition, in order to facilitate the placement and removal of parts, in this embodiment, a position of the part processing mechanism 3 is reserved and does not participate in part processing. When the device table 1 drives the part to rotate to the position of the part processing mechanism 3, the processed part is removed and replaced with a new unprocessed part.
