DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0044] like Figures 1 to 19 As shown, the multi-directionally adjustable machining center workbench of the present invention includes a body 1 and a workbench 2 disposed within the body 1 for placing workpieces 3. The workbench 2 is used to place workpieces 3 to be processed. A certain number of workpieces 3 can be placed in a placement slot 4 on the workbench 2, allowing workers to avoid operating the machining center for a certain period of time, leaving their spare time for other purposes. This not only enables automated processing of workpieces 3, but also effectively saves workers' time, achieving multiple work efficiency within a limited time and increasing production.

[0045] In addition, the drive mechanism 5 and the rotating mechanism 6 are driven by the same motor, which can reduce the use of parts and avoid occupying more space within the machining center. The motor drives the drive rod 7 to rotate, keeping the drive rod 7 in continuous rotation, while the drive disk 8 converts kinetic energy through the first driver 9, keeping the drive rod 7 in rotation and driving the driven rod 10, which in turn drives the drive disk 8 to rotate.

[0046] The rotating disk 11 in the rotating mechanism 6 is driven by the second driver 13 on the driven shaft 12 to push the second bevel gear 14 to maintain meshing connection with the first bevel gear 15 on the drive rod 7 to achieve energy conversion, and the driven shaft 12 is driven to rotate by the drive rod 7, and finally the rotation of the rotating disk 11 is achieved. The rotating disk 11 and the drive disk 8 can not only keep rotating at the same time, but also achieve the rotation of a single rotating disk 11 or the drive disk 8. When the drive disk 8 rotates, multiple rotating disks 11 can be rotated to the specified position, and when the rotating disk 11 rotates, a single workpiece 3 can be accurately controlled to reach the specified position, which is convenient for the robot clamping processing.

[0047] The workbench 2 is composed of a driving mechanism 5 and a rotating mechanism 6. The rotating mechanism 6 is provided at multiple locations and is evenly mounted on the driving mechanism 5. The rotating mechanism 6 can be mounted according to actual conditions. The driving mechanism 5 drives the rotating mechanism 6 to rotate while rotating itself.

[0048] The drive mechanism 5 comprises a drive plate 8, a drive rod 7, a driven rod 10, and a drive assembly, which comprises a motor. The drive rod 7 is mounted on the drive assembly and driven by the motor. A through-hole 16 is formed in the center of the drive rod 7, which receives the driven rod 10. The inner diameter of the through-hole 16 can be slightly larger than the diameter of the driven rod 10, allowing the driven rod 10 to rotate within the hole while also limiting its position.

[0049] The driving disc 8 is mounted on the upper end of the driven rod 10, and a driven gear disc 17 is provided at the lower end of the driving disc 8. A driving gear disc 18 is provided on the driving rod 7. A first driver 9 is provided on the driving rod 7. The first driver 9 pushes the driving gear disc 18 to engage with the driven gear disc 17. When the driving rod 7 is required to drive the driving disc 8 to rotate, it is only necessary to energize the first driver 9. The upper end of the first driver 9 is kept to generate a magnetic force, which pushes the driving gear disc 18 upward, so that the teeth 19 on the driving gear disc 18 and the driven gear disc 17 engage with each other, thereby causing the driving rod 7 to drive the driving disc 8 to rotate.

[0050] In order to keep the driving disc 8 rotating smoothly on the driving rod 7, a plane bearing 20 is provided between the driving gear disc 18 and the driven gear disc 17, and the driven gear disc 17 rotates on the plane bearing 20.

[0051] In addition, a cavity 43 is provided in the middle of the driving gear disc 18 , and the cavity 43 is used to accommodate the plane bearing 20 , so as to ensure that the driving gear disc 18 and the driven gear disc 17 are not affected after being engaged.

[0052] The driving rod 7 is further provided with a first bevel gear 15 , which can rotate together with the driving rod 7 .

[0053] The rotating mechanism 6 is provided with a driven shaft 12, a fixed part 21, a second bevel gear 14 and a rotating disk 11. An electromagnetic part 22 is provided on the driving disk 8. The electromagnetic part 22 is composed of an annular seat 23 and multiple electromagnetic columns 24, wherein a release area 25 is left between two electromagnetic columns 24.

[0054] The electromagnetic post 24 is not provided in the release zone 25 , so that when the retaining member 28 is in the position where the electromagnetic post 24 is located, it can be attracted by the electromagnetic post 24 and move in the active area 26 , compressing downward, and the deformable arm 27 is subjected to external force, causing deformation, thereby clamping the workpiece 3 in the placement slot 4 . When the retaining member 28 rotates to the release zone 25 , the electromagnetic post 24 is no longer present at the lower end of the retaining member 28 , so it is not attracted by the magnetic force. As a result, the attraction block 29 on the retaining member 28 returns to its original shape under the action of the deformable arm 27 .

[0055] In addition, an electromagnetic column 24 can be added in the release area 25. The magnetic direction of the electromagnetic column 24 is the same as the magnetic direction of the lower end of the magnet 30 inside the attraction block 29, achieving the effect of same-direction repulsion, and assisting the deformable arm 27 to restore the attraction block 29 to its original state.

[0056] Driven shaft 12 is mounted to the lower end of drive disc 8 via fixing member 21, ensuring that rotating mechanism 6 can rotate along with drive mechanism 5, but rotating mechanism 6 can rotate independently on drive mechanism 5. Rotating disc 11 is mounted on drive disc 8, and driven shaft 12 passes through drive disc 8 and is connected to rotating disc 11. A second bevel gear 14 is mounted on driven shaft 12, and a second driver 13 is also provided on driven shaft 12. Second driver 13 drives second bevel gear 14 into meshing connection with first bevel gear 15.

[0057] Electromagnet 22 is located at the lower end of rotating disk 11. Rotating disk 11 rotates on electromagnetic 22, but electromagnetic 22 does not rotate with it. Rotating disk 11 is equipped with multiple retaining members 28, which can be used to limit the position of workpiece 3. Rotating disk 11 is provided with placement slots 4 corresponding to the positions of retaining members 28, located at both ends of retaining member 28. When electromagnetic 22 is energized and generates magnetic force, it attracts magnet 30 in the center of retaining member 28, causing attraction block 29 to move downward and adhere to thin sheet 31.

[0058] The bottom of the rotating disk 11 is provided with an annular groove 32 for accommodating the electromagnetic member 22 , which allows the electromagnetic column 24 to be located therein and keeps the electromagnetic column 24 as close to the thin sheet portion 31 as possible, thereby facilitating better attraction of the retaining member 28 .

[0059] The rotating disk 11 is composed of an inner ring 33 and an outer ring 34, with a clamping area 35 formed between the inner ring 33 and the outer ring 34. The placement groove 4 is located on the inner ring 33 and the outer ring 34. A thin plate portion 31 is provided in the middle of the clamping area 35. The thin plate portion 31 is located at the upper end of the annular groove 32, and the retaining member 28 is located on the thin plate portion 31.

[0060] The retaining member 28 is forced to move downward, clamping the workpiece 3 placed in the placement slots 4 at both ends. When the external force disappears, the retaining member 28 returns to its original state. The retaining member 28 is composed of an attraction block 29, a symmetrical deformable arm 27, a support portion 36, and a mounting portion 37. The symmetrical mounting portions 37 form an active area 26 for the displacement of the attraction block 29. The mounting portion 37 is located at the lower end of the support portion 36, and the deformable arm 27 is located on both sides of the attraction block 29. The deformable arm 27 is located at the upper end of the support portion 36. The rotating disk 11 is provided with a mounting slot 38, and the retaining member 28 is inserted into the mounting slot 38 through the mounting portion 37.

[0061] A magnet 30 is positioned in the center of the attraction block 29. A clamping opening 39 is provided on the support portion 36, which is designed to engage with the placement grooves 4 on the outer ring 34 and inner ring 33. The deformable arm 27 is provided with an arcuate concave surface 40 that engages with the workpiece 3. This arcuate concave surface 40 is able to conform to the outer wall of the workpiece 3, achieving elastic clamping of the workpiece 3.

[0062] The first driver 9 is located between the first bevel gear 15 and the driving gear disc 18. A limiting tooth 41 is provided between the first driver 9 and the driving gear disc 18. The driving rod 7 is provided with a limiting groove 42 that cooperates with the limiting tooth 41. This ensures that the first driver 9 and the driving gear disc 18 can rotate together with the driving rod 7.

[0063] The first driver 9 and the second driver 13 are electromagnets. When energized, the first driver 9 and the second driver 13 generate magnetic force, and then push the driving toothed disc 18 and the second bevel gear 14 to move upward. When not energized, they move downward under the action of their own gravity.

[0064] The clamping opening 39 on the support portion 36 is used to cooperate with the placement groove 4 to maintain the position of the workpiece 3, but the clamping force requires the deformation of the deformable arm 27 before it can be clamped. Both ends of the holder 28 can clamp the workpiece 3, which is conducive to placing more workpieces 3.

[0065] like Figure 17As shown, the placement groove 4 is partially located in the clamping area 35 and the other part is located on the outer ring 34 or the inner ring 33. Since there is a height difference between the outer ring 34 and the inner ring 33 and the bottom surface of the clamping area 35, the holding member 28 can better clamp the workpiece 3.

[0066] like Figure 18 As shown, the S-direction indicates release zone 25. When retaining member 28 reaches this zone, it is no longer attracted by the magnetic force. Retaining member 28 recovers under the elastic force of deformable arm 27, pushing attraction block 29 upward. Furthermore, the spacing of electromagnetic posts 24 ensures that retaining member 28 remains attracted to them even as rotating disk 11 rotates. After passing one electromagnetic post 24, retaining member 28 immediately reaches the next electromagnetic post 24, ensuring that the magnetic force persists. The magnetic force only dissipates when it reaches release zone 25.

[0067] like Figure 19 As shown, when the electromagnetic column 24 at the lower end of the holder 28 is no longer energized, the attraction block 29 is pushed in the direction P by the elastic force of the deformable arm 27, maintaining the deformable arm 27 in a straight state. As a result, the holder 28 no longer clamps the workpiece 3, and the workpiece 3 can be clamped by the robot arm to the processing location.

[0068] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
