[0028] like Figures 1-4 As shown, this invention discloses a horizontal machining center for workpieces, comprising a machine body 1. A door 3 is hinged to the side of the machine body 1, and the door 3 has a window in the middle. A tempered glass 22 is connected to the middle of the door 3 to facilitate observation of the internal environment by the operator. A machining device 2 for machining workpieces is connected to the top of the machine body 1. A discharge groove 10 is provided at the bottom of the machine body 1 to collect debris generated during workpiece machining. The width of the discharge groove 10 is greater than that of the placement table 5 to prevent the placement table 5 from contacting the discharge groove 10 when rotating. A stabilizing device 4 for stabilizing the placement table 5 is slidably connected to the upper part of the discharge groove 10. Two stabilizing devices 4 are located on either side of the placement table 5. Each stabilizing device 4 includes: a caster wheel 44, a first telescopic rod 43, a crossbar 42, a support rod 41, a first spring 45, and a pressing block 46. One end of the support rod 41 is rotatably connected to the caster wheel 44, and the crossbar 42 is fixedly connected to the support rod 41. Two first telescopic rods 43 are located at both ends of the crossbar 42, and are rotatably connected to the caster wheel 44, allowing the support rod 41 to tilt. The other end of the support rod 41 is slidably connected to a placement platform 5, which is used to place the workpiece. A first groove 9 is formed at the bottom of the placement platform 5, and the other end of the support rod 41 extends into and is slidably connected to the first groove 9. Two extrusion blocks 46 are located on both sides of the support rod 41 and are slidably connected to the first groove 9. The first spring 45 is located between the extrusion block 46 and the first groove 9. In its normal state, the first spring 45 is in a supporting position, ensuring that the support rod 41 remains in the center of the placement platform 5, and that the first spring 45 can reset the support rod 41 after it moves.

[0029] like Figures 2-5As shown, the lower part of the placement platform 5 is connected to a rotating device 6 that drives the placement platform 5 to rotate. The rotating device 6 includes: a fixed shell 61, a first connecting rod 62, a second connecting rod 64, a third connecting rod 63, a first gear 65, a second gear 68, a first sector gear 66, and a second sector gear 67. The fixed shell 61 is fixedly connected to the lower part of the placement platform 5, allowing the placement platform 5 to move the fixed shell 61. The first connecting rod 62 passes through the body 1 and is rotatably connected to the body 1. A handle is connected to the first connecting rod 62 located on the outside of the body 1. The first connecting rod 62 is hollow inside. One end of the second connecting rod 64 is located inside the first connecting rod 62 and is slidably connected to the first connecting rod 62. Rotating the handle can drive the second connecting rod 64 to rotate. One end of the second connecting rod 64 passes through the fixed shell 61 and extends into the fixed shell 61. The second connecting rod 64 is rotatably connected to the fixed shell 61. The second connecting rod 64 is fixedly connected to the first gear 65, allowing the second connecting rod 64 to drive the first gear 65 to rotate. The first sector gear 66 is fixedly connected to the upper part of the fixed housing 61, and the first gear 65 is meshed with the first sector gear 66. The first sector gear 66 prevents the first gear 65 from driving the first sector gear 66 to rotate too much, thus preventing the processing device 2 from processing the workpiece on the placement table 5. When the placement table 5 moves via the fixed housing 61, it can drive the second connecting rod 64 to move, thereby keeping the first gear 65 and the first sector gear 66 constantly meshed. The second connecting rod 64 is hollow inside, and one end of the third connecting rod 63 is located inside the second connecting rod 64 and is slidably connected to it. When the third connecting rod 63 rotates inside the second connecting rod 64, it does not drive the second connecting rod 64 to rotate. The third connecting rod 63 passes through the fixed housing 61 and is slidably connected to it; when the third connecting rod 63 rotates, it does not drive the fixed housing 61 to rotate. The other end of the third connecting rod 63 is rotatably connected to the body 1. The third connecting rod 63 passes through the second gear 68 and is slidably connected to the second gear 68. The teeth of the first gear 65 are smaller than the teeth of the second gear 68. This allows the first gear 65 to be rotated slightly to adjust the angle of the fixed housing 61. The second sector gear 67 is located on the upper part of the fixed housing 61 and is fixedly connected to the fixed housing 61. The second gear 68 meshes with the second sector gear 67. The angle of the fixed housing 61 can be quickly rotated through the second gear 68. The second gear 68 drives the second sector gear 67 to rotate with the fixed housing 61. The second gear 68 has a circular groove 7. The second sector gear 67 is connected to a connecting rod 86. The other end of the connecting rod 86 extends into the circular groove 7 and is slidably connected to the circular groove 7. By connecting one end of the connecting rod 86 to the second sector gear 67 and sliding the other end in the circular groove 7, the second gear 68 is moved laterally, so that the second gear 68 is always meshed with the second sector gear 67.

[0030] The working principle of the above scheme is as follows: Open the hatch 3 and place the workpiece on the upper part of the placement platform 5. At this time, start the processing device 2 to process the workpiece. When processing other parts of the workpiece is required, rotate the third connecting rod 63. The third connecting rod 63 drives the second gear 68 to rotate, which in turn drives the second sector gear 67 to rotate. The second sector gear 67 drives the fixed housing 61 and the placement platform 5 to rotate rapidly. When the placement platform 5 rotates to its approximate position, rotate the first connecting rod 62 to drive the second connecting rod 64 and the first gear 65 to rotate. The first gear 65 drives the first sector gear 66 to rotate slightly, allowing the placement platform 5 to rotate slightly, enabling the processing device 2 to perform fine processing on the workpiece. When the placement platform 5 rotates, the support rod 41 rotates under force. At this time, the first telescopic rod 43 compresses the roller and moves accordingly, and the support rod 41 slides within the first slide groove 9. When the placement platform 5 rotates to a horizontal position, the first spring 45 drives the pressing block 46 to rebound, causing the support rod 41 to return to its original position. The support rod 41 prevents the placement platform 5 from falling.

[0031] The beneficial effects of the above scheme are as follows: the rotating device 6 drives the placement table 5 to rotate, allowing the workpiece on the placement table 5 to be processed from multiple angles; the first gear 65 connected inside the rotating device 6 drives the placement table 5 to rotate roughly and quickly, and then the second gear 68 drives the placement table 5 to rotate precisely to achieve fine adjustment. The stabilizing device 4 ensures that the horizontal height of the placement table 5 does not change during rotation, preventing the placement table 5 from falling.

[0032] In one embodiment of the present invention, such as Figures 6-9As shown, the upper perimeter of the placement platform 5 is connected to multiple fixing devices 8 for fixing workpieces. Each fixing device 8 includes: a first spiral rod 81, a rotating block 82, a pushing block 83, an air chamber 84, a second spring 85, a pressing plate 89, a connecting rod 86, a support platform 87, and a lowering plate 88. The placement platform 5 has multiple sliding grooves 9, all angled, allowing components such as the pushing block 83 to retract within the placement platform 5 to fix the workpiece. Multiple first spiral rods 81 are located within the sliding grooves 9 and are rotatably connected to them. The first spiral rod 81 passes through the rotating block 82 and is threadedly connected to it. Rotating the rotating block 82 causes it to push the pushing block 83. The first spiral rod 81 passes through the lower end of the pushing block 83 and is slidably connected to it. Rotating the rotating block 82 causes it to rotate on the first spiral rod 81, causing it to move in contact with the pushing block 83. The air chamber 84 is slidably connected to the upper part of the placement platform 5. The upper end of the pushing block 83 is fixedly connected to the air chamber 84, and the air chamber 84 is moved by the movement of the pushing block 83. The extrusion plate 89 is located inside the air chamber 84 and is slidably and sealingly connected to the air chamber 84. The second spring 85 is located between the extrusion plate 89 and the air chamber 84. The second spring 85 can cause the extrusion plate 89 to return to its original position after being extruded and extruded inside the air chamber 84. One end of the connecting rod 86 passes through the air chamber 84 and is fixedly connected to the extrusion plate 89. The other end of the connecting rod 86 is fixedly connected to the support platform 87. The workpiece is placed on the support platform 87, and the weight of the workpiece causes the connecting rod 86 and the extrusion plate 89 to descend. The side of the air chamber 84 is connected to an air outlet pipe 11. The air outlet pipe 11 is slidably and sealingly connected to a descending rod 12. The descending rod 12 is fixedly connected to a descending plate 88. The airflow in the air outlet pipe 11 causes the descending rod 12 and the descending plate 88 to descend to extrude and clamp the workpiece. A ramp 15 is hinged to the side of the support platform 87. A slot 14 is also provided on the upper part of the support platform 87 so that the ramp 15 can be positioned within the slot 14 to prevent it from damaging the workpiece. A torsion spring 13 is connected to the hinge point between the ramp 15 and the support platform 87. The torsion spring 13 keeps the ramp 15 in an inclined position, and the ramp 15 can return to its original position when it is not in contact with the workpiece. A second telescopic rod 16 is connected to the side of the ramp 15. Multiple second telescopic rods 16 are evenly arranged on the side of the ramp 15, and each of the multiple second telescopic rods 16 is connected to a segment 17, which are hinged together. The multiple second telescopic rods 16 drive the segments 17, thereby pressing against the workpiece and fixing it in place.

[0033] The working principle of the above scheme is as follows: When it is necessary to fix the workpiece, rotating block 82 is rotated to move pushing block 83. Pushing block 83 drives air chamber 84 to move, allowing the workpiece to be placed on the support platform 87. When the workpiece is placed on the support platform 87, the workpiece first contacts the inclined plate 15. The inclined plate 15 is subjected to force to rotate the second telescopic rod 16, causing segment 17 to contact the side of the workpiece. The second telescopic rod 16 is subjected to force to retract, thereby clamping the side of the workpiece. Moreover, through multiple segments 17, the second telescopic rod 16 can also contact and clamp irregular parts of the workpiece. The workpiece continues to descend, pressing the inclined plate 15 into the slot 14. When the workpiece contacts the support platform 87, the support platform 87 is subjected to force to drive the connecting rod 86 to descend. The connecting rod 86 causes the extrusion plate 89 to descend. The extrusion plate 89 compresses the air in the air chamber 84 into the air outlet pipe 11. The gas in the air outlet pipe 11 applies pressure to the descending rod 12. The descending rod 12 drives the descending plate 88 to press against the workpiece, fixing the workpiece. After the workpiece is processed, it is lifted so that it no longer applies pressure to the inclined plate 15. The torsion spring 13 is no longer under force and drives the inclined plate 15 to reset. At this time, the workpiece no longer applies pressure to the support platform 87. The second spring 85 drives the pressing plate 89 to reset. The pressing plate 89 moves to draw air from the air outlet pipe 11 into the air chamber 84. At this time, the descending rod 12 is forced to drive the descending plate 88 to rise and reset so that the workpiece is no longer clamped, making it easier to remove the workpiece.

[0034] The beneficial effects of the above solution are: the workpiece can be clamped from the top and bottom and from the side by the fixing device 8, which increases the stability of the workpiece; the workpiece is clamped by its own weight to prevent the workpiece from being damaged by the fixing device 8.

[0035] In one embodiment of the present invention, such as Figures 1-6 As shown, a second spiral rod 18 is rotatably connected to the middle of the machine body 1. The second spiral rod passes through the lower part of the placement platform 5 and is threadedly connected to the placement platform 5. Rotating the second spiral rod 18 moves the placement platform 5, while the stabilizing device 4 prevents the placement platform 5 from falling. A support rod 19 is connected to the lower part of the fixed shell 61, and multiple brush rods 20 are connected to the lower part of the support rod 19. The fixed shell 61 drives the brush rods 20 to move, thereby sweeping out the debris in the discharge groove 10. A through groove 21 is opened on the side of the machine body 1. The diameter of the through groove 21 is larger than the diameter of the placement platform 5, allowing a portion of the placement platform 5 to extend out of the through groove 21.

[0036] The working principle of the above scheme is as follows: the placement platform 5 is moved by rotating the second helical rod 18, and the stabilizing device 4 prevents the placement platform 5 from tipping over, keeping it in a horizontal state. Because it is the second helical rod 18 that rotates, the placement platform 5 is only rotated by friction from the second helical rod 18, so the stabilizing device 4 can prevent the placement platform 5 from tipping over. When the placement platform 5 moves, it drives the brush rod 20 to move, causing the brush rod 20 to sweep out the debris from the discharge groove 10. A portion of the placement platform 5 extends out of the through groove 21, allowing the brush rod 20 to sweep the debris out of the discharge groove 10.

[0037] The beneficial effects of the above scheme are as follows: by rotating the second spiral rod 18 to move the placement table 5, the brush rod 20 sweeps out the flying debris in the discharge groove 10; and by moving the placement table 5 through the second spiral rod 18, the processing device 2 can process other parts of the workpiece.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
