Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example 1: Please refer to Figure 1 - Figure 9 This embodiment of a platform-moving cylindrical wood carving machine includes a base 1 and a slider plate 2. A motor cabinet 6 is provided on one side of the base 1. A head cover 5 is fixedly connected to the top of the slider plate 2. Two bracket columns 15 are fixedly connected to both sides of the base 1. A bracket cover 3 is fixedly connected to the top of the bracket column 15. A bellows cover 4 is fixedly connected to one end of the bracket cover 3. A fixed beam 7 is provided inside the bellows cover 4. A first motor 8 is fixedly connected to the top of the fixed beam 7. A first lead screw 9 is fixedly connected to one end of the first motor 8. A first fixed block 10 is rotatably connected to one end of the first lead screw 9. The bottom of the first fixed block 10 is fixedly connected to the top of the fixed beam 7. A first nut seat 11 is threadedly connected to one end of the first lead screw 9.

[0031] The machine starts with the first motor 8, which drives the first lead screw 9 to rotate. The lead screw 9 then moves the first nut seat 11, which in turn moves the mounting plate 22 along the X-axis. The reciprocating linear motion on the X-axis is achieved by the first motor 8. The X-axis transmission is fixed on the gantry frame, which remains stationary during machine operation, ensuring greater stability. Traditional wood carving equipment mostly uses a moving gantry frame, but this new carving machine uses a static gantry frame, making the machine more stable in both the X and Z directions.

[0032] Secondly, by setting up the bracket cover 3, the bellows cover 4 and the head cover 5, the dust such as wood chips will not enter the transmission parts during the engraving process, thus ensuring the safe production of the equipment.

[0033] Furthermore, a mounting plate 22 is fixedly connected to one side of the first nut seat 11, a third motor 23 is provided on the top of the mounting plate 22, a third lead screw 24 is fixedly connected to the bottom of the third motor 23, a third fixing block 25 is rotatably connected to the bottom of the third lead screw 24, a third nut seat 26 is threadedly connected to one end of the third lead screw 24, a third nut seat 26 is fixedly connected to the inner side of the slider plate 2 on one side, a main shaft fixing plate 42 is fixedly connected to the outer side of the slider plate 2, a plurality of fifth motors 44 are fixedly connected to one side of the main shaft fixing plate 42, a motor clamp 43 is provided inside the fifth motor 44, and an engraving tool 41 is fixedly connected to the bottom of the motor clamp 43;

[0034] Among them, starting the third motor 23 will drive the third lead screw 24 to rotate, the third lead screw 24 will drive the third nut seat 26 to move, and the third nut seat 26 will drive the slider plate 2 to move along the Z-axis. The slider plate 2 will reciprocate linear motion on the Z-axis by being driven by the third motor 23.

[0035] Secondly, by setting up multiple engraving tools 41 and adopting a multi-head simultaneous operation mode, the production efficiency is improved. The high-speed rotation of the fifth motor 44 drives the engraving tool 41 to complete the engraving operation along the A-axis. Water cooling is used to extend the service life of the tool. The fifth motor 44 has water inlet and outlet holes for immediate cooling. Each fifth motor 44 is equipped with an air switch, which can turn on a single spindle motor at any time without affecting the operation of other spindles.

[0036] Furthermore, a second motor 16 is fixedly connected to the top of the base 1, a second lead screw 17 is fixedly connected to one end of the second motor 16, a second fixing block 18 is rotatably connected to one end of the second lead screw 17, the bottom of the second fixing block 18 is fixedly connected to the top of the base 1, a second nut seat 19 is threadedly connected to one end of the second lead screw 17, and a mobile platform body 30 is fixedly connected to the top of the second nut seat 19.

[0037] Among them, starting the second motor 16 will drive the second lead screw 17 to rotate, the second lead screw 17 will drive the second nut seat 19 to move, and the second nut seat 19 will drive the moving platform body 30 to move along the Y-axis. The reciprocating linear motion on the Y-axis is achieved by driving the second motor 16.

[0038] Secondly, the operator installs the workpiece to be engraved onto the clamping station in sequence and clamps it. Through the computer software system programming program, the engraving machine controller controls the XYZ three-axis joint motion of the equipment and drives the engraving tool 41 to rotate to complete the engraving operation.

[0039] Furthermore, two first guide rails 13 are fixedly connected to one side of the fixed beam 7, and a first slider 14 is slidably connected to the outside of the first guide rail 13. One side of the first slider 14 is fixedly connected to the mounting plate 22, and a limit block 12 is fixedly connected to one side of the fixed beam 7.

[0040] When the first nut seat 11 drives the mounting plate 22 to move, the mounting plate 22 will drive the first slider 14 to move along the outside of the first guide rail 13, so that the mounting plate 22 remains stable when it moves. At the same time, a limit block 12 is provided to limit the movement of the mounting plate 22.

[0041] Furthermore, a plurality of third guide rails 27 are fixedly connected to one side of the mounting plate 22, and a third slider 28 is slidably connected to the outside of the third guide rails 27. One side of the third slider 28 is fixedly connected to the inside of the slider plate 2.

[0042] When the third nut seat 26 drives the slider plate 2 to move, the slider plate 2 will drive the third slider 28 to move along the outside of the third guide rail 27, limiting the movement of the slider plate 2, so that the slider plate 2 remains stable when it moves.

[0043] Furthermore, the top two sides of the base 1 are fixedly connected to the second guide rail 20, the top of the second guide rail 20 is slidably connected to the second slider 21, the top of the second slider 21 is fixedly connected to the mobile platform base 29, and the top of the mobile platform base 29 is fixedly connected to the bottom of the mobile platform body 30.

[0044] When the second nut seat 19 drives the mobile platform body 30 to move, the mobile platform body 30 will drive the second slider 21 to move along the outside of the second guide rail 20, thereby limiting the movement of the mobile platform body 30 and keeping the mobile platform body 30 in a stable state when it moves.

[0045] Secondly, regularly and quantitatively supplying lubricating grease to the guide rails and lead screws extends the service life of components and ensures machining precision and accuracy;

[0046] Furthermore, a reducer mounting bracket 31 is fixedly connected to the top of one end of the mobile platform body 30. A fourth motor 32 is fixedly connected inside the reducer mounting bracket 31. A coupling 34 is fixedly connected to one end of the fourth motor 32. Multiple worm gear reducers 33 are assembled and connected to the coupling 34. A worm gear pin 35 is assembled and connected to one side of the worm gear reducer 33. Two circular rails 36 are fixedly connected inside the mobile platform body 30. A circular rail slider 37 is slidably connected to the outside of the circular rails 36. A crossbeam 38 is fixedly connected to the top of the circular rail slider 37. A tailstock pin assembly 40 is provided on one side of the crossbeam 38. Two locking screws 39 are fixedly connected to the inside of the reducer mounting bracket 31. One end of the locking screw 39 is movably connected to the inside of the crossbeam 38.

[0047] The tailstock ejector assembly 40 is installed inside the crossbeam 38. By rotating the tailstock knob 4001, the tailstock ejector 4002 can move forward and backward, and the workpiece is installed between the tailstock ejector assembly 40 and the turbine ejector 35. The tailstock ejector assembly 40 moves forward to clamp the workpiece and tightens the locking nut.

[0048] Secondly, the crossbeam 38 is mounted on the circular rail slider 37 by means of pads. The operator can adjust the front and back distance according to the workpiece size. The crossbeam 38 is fixedly connected to the reducer fixing frame 31 by using the locking screw 39. Then, the nut at one end of the locking screw 39 is locked. Local adjustment can be made by using the tailstock ejector assembly 40 to move forward and backward, and the workpiece is clamped or loosened.

[0049] Furthermore, the tailstock ejector assembly 40 includes a tailstock knob 4001 and a tailstock ejector 4002. One end of the tailstock knob 4001 is fixedly connected to the tailstock ejector 4002, and the tailstock ejector 4002 is rotatably connected to the inside of the crossbeam 38.

[0050] The fourth motor 32 rotates under the control system, which drives the coupling 34 to rotate and transmits power to the worm gear reducer 33. The worm gear reducer 33 rotates to reduce speed and increase torque, which is then transmitted to the worm gear ejector 35. The tailstock ejector assembly 40 together positions and clamps the workpiece. The rotation of the worm gear reducer 33 drives the workpiece to rotate, realizing the rotational movement of the A-axis. The tailstock ejector assembly 40 consists of a tailstock knob 4001 and a tailstock ejector 4002. The workpiece is clamped and released by rotating the knob clockwise and counterclockwise.

[0051] Secondly, the mobile platform body 30 supports the entire structure and moves the entire A-axis structure back and forth along the Y-axis. The crossbeam 38 fixes multiple sets of worm gear reducers 33, which are connected in series by couplings 34. A fourth motor 32 drives the multiple sets of worm gear reducers 33 in linkage, thereby realizing the simultaneous linkage processing of multiple workpieces. The circular rail 36 guides the forward and backward Y-axis movement of the crossbeam 38. The crossbeam 38 supports and fixes multiple sets of tailstock ejector assembly 40. The worm gear ejector 35 and the tailstock ejector assembly 40 can be divided into 1-16 linkage groups according to market demand.

[0052] Furthermore, the A-axis is characterized by its suitability for clamping and machining large workpieces. Multiple A-axis are driven by a high-power fourth motor 32, which drives multiple sets of worm gear reducers 33 in a linkage manner, greatly improving the output torque of each set of worm gear reducers 33 to achieve high power output and effectively complete the rotary machining of large workpieces.

[0053] Secondly, the system is equipped with an electrical control module, which includes a motor cabinet 6, a computer host, a monitor, a keypad, push-button switches, an emergency stop switch, alarm lights, and CNC system software for the engraving machine. The electrical control cabinet is equipped with a USB interface.
