[0036] Reference Figures 1-5According to an embodiment of a workpiece internal hole deburring and chip removal device of the present invention, it includes a machine base 11, a frustum 12 is provided on the machine base 11, a cleaning chamber 13 with an upward opening and penetrating the frustum 12 is provided in the machine base 11, and a support platform 14 capable of lifting and rotating is installed in the cleaning chamber 13 through a control component, a clamp 15 is installed on the support platform 14, and a workpiece is loaded into the clamp 15 from above;

[0037] An annular groove 16 is provided on the upper side of the frustum 12 outside the cleaning chamber 13, and a plurality of processing devices for processing the workpiece in the fixture 15 are distributed around the annular groove 16.

[0038] The cleaning chamber 13 is filled with cleaning fluid, and the machine base 11 is equipped with a filter device that acts on the cleaning fluid.

[0039] The processing flow for the workpiece is as follows:

[0040] First, the worker or robot places the workpiece in the fixture 15 from top to bottom. At this time, both the fixture 15 and the workpiece are at the top. After clamping, the processing device works to deburr the holes in the workpiece.

[0041] After processing, the control component controls the support platform 14 and the clamp 15 to sink, so that the workpiece sinks into the cleaning fluid. Then, the control component controls the clamp 15 to rotate, so that the debris in the workpiece can be thrown out into the cleaning fluid under the action of inertial force. The machine base 11 is equipped with an ultrasonic generator (not shown in the figure). At this time, the ultrasonic generator can work and perform ultrasonic cleaning on the workpiece (the ultrasonic waves can be transmitted in the cleaning fluid to clean the workpiece located therein, which is the prior art and will not be described in detail here). After cleaning, the control component controls the clamp 15 to rise. During this process, the clamp 15 can rotate to spin dry the workpiece inside. When the workpiece returns to the highest position, the deburring and cleaning of the workpiece is completed. During this process, the filtration device can filter the debris in the cleaning fluid.

[0042] In this embodiment, the bottom surface of the fixture 15 is provided with a through groove to facilitate drainage and chip removal from the workpiece.

[0043] The control component includes a turntable 21 rotatably connected to the cleaning chamber 13, a lifting groove 22 with an upward opening provided in the turntable 21, and a support platform 14 slidably connected to the lifting groove 22.

[0044] The lifting groove 22 has a downward through circular groove 26 in its curved surface, and two threaded shafts 27 symmetrically distributed on the upper side of the circular groove 26 are rotatably connected to it. The threaded shafts 27 extend downward into the cleaning fluid, and the lower end of the support platform 14 is equipped with a base plate 28 threaded to the threaded shafts 27.

[0045] It also includes a drive mechanism for driving the turntable 21 to rotate and the threaded shaft 27 to rotate. When the turntable 21 rotates, the workpiece will rotate, and when the threaded shaft 27 rotates, it will drive the workpiece to move up and down.

[0046] The driving mechanism includes a first gear ring 23 fixed to the bottom surface of the turntable 21, and a drive shaft 24 is rotatably connected to the wall of the cleaning chamber 13. A first gear meshing with the first gear ring 23 is mounted on the drive shaft 24, and a first motor 25 for driving the drive shaft 24 is installed inside the truncated cone 12.

[0047] Each of the threaded shafts 27 is equipped with a second gear, and a second gear ring 29 meshing with the second gear is rotatably connected in the circular groove 26. The turntable 21 is equipped with a second motor (not shown in the figure) for driving the second gear ring 29 to rotate.

[0048] When the No. 1 motor 25 is powered on, it will drive the No. 1 gear ring 23, thereby driving the turntable 21 and the bearing platform 14 and the clamp 15 inside it to rotate.

[0049] When the second motor is powered on, it will first drive the second gear ring 29 to rotate, and then drive the two threaded shafts 27 to rotate, thereby driving the base plate 28, the support platform 14 and the clamp 15 to rise and fall.

[0050] Furthermore, both the support platform 14 and the base plate 28 are provided with a second through hole that connects to the first through hole, so as to facilitate drainage and chip removal within the workpiece.

[0051] Furthermore, the filtration device includes a tubular filter 31 and a water pump 32 installed inside the machine base 11. The first inlet of the tubular filter 31 is connected to the axis of the bottom surface of the cleaning chamber 13, and the first outlet of the tubular filter 31 is connected to the water pump 32. The second outlet of the water pump 32 flows back into the cleaning chamber 13. An output shaft 33 for driving the water pump 32 is rotatably connected to the side of the cleaning chamber 13. Both the output shaft 33 and the drive shaft 24 are fitted with pulleys, and the two pulleys are connected by a synchronous belt. The specific structure of the water pump 32 and the principle of driving the water pump 32 through the output shaft 33 are existing technologies and will not be described in detail here.

[0052] When the drive shaft 24 rotates, it will also drive the water pump 32 to work through the synchronous belt. At this time, the cleaning liquid in the cleaning chamber 13 will be filtered by the tubular filter 31 and then pumped out by the water pump 32 and flowed back into the cleaning chamber 13.

[0053] It should be further noted that since the water pump 32 is also driven by the first motor 25, and the first motor 25 drives the turntable 21 to rotate when it is working, it can be considered that the water pump 32 only works when the turntable 21 is rotating. When the turntable 21 rotates, the threaded shaft 27 extending into the cleaning fluid in the cleaning chamber 13 will rotate and agitate the cleaning fluid, so that the cleaning fluid forms a vortex flow field, and the debris in the cleaning fluid can be concentrated towards the center of the vortex. Since the first inlet of the tubular filter 31 is connected to the axis of the bottom surface of the cleaning chamber 13, the debris at the center of the vortex can be concentrated and sucked up. This arrangement improves the filtration effect and efficiency of the cleaning fluid.

[0054] During the upward lifting of the fixture 15, the rotating turntable 21 can also perform a spin-drying operation on the fixture and the workpiece inside it.

[0055] In the above embodiment, the second water outlet in the water pump 32 is connected to the cleaning chamber 13. In other embodiments, the second water outlet is upward and directly faces the treatment device so as to be able to rinse the treatment device.

[0056] The processing device includes an arc-shaped plate 41 inserted downward into the annular groove 16. The upper end of the arc-shaped plate 41 is bent into a horizontal plate 42 facing the axis of the frustum 12. A mounting base 43 is fixed on the horizontal plate 42. A cylinder 44 is fixed inside the mounting base 43. A cleaning rod 45 is installed at the end of the piston rod inside the cylinder 44.

[0057] A locking pin 46 is screwed into the outer curved surface of the machine base 11 and inserted into the arc plate 41.

[0058] The processing device is provided with several units distributed at equal angles around the axis of the frustum 12. The cylinder 44 can control the length of the extended cleaning rod 45. When the cleaning rod 45 is extended, it can enter the workpiece in the clamp 15 and deburr the holes in the workpiece. That is, when the clamp 15 is inserted into the workpiece, the sprue material in the hole will be pushed off and separated from the aluminum part.

[0059] In addition, the support platform 14 can rotate so that sprue material in holes at different angles can be processed.

[0060] In addition, in a second embodiment of the processing device, the mounting base 43 is slidably connected to the horizontal plate 42, and a chamfering motor is installed inside the mounting base 43. A chamfering cutter is installed at the end of the motor shaft inside the chamfering motor, and a positioning cylinder for controlling the position of the mounting base 43 is installed on the horizontal plate 42. This processing device can be used to chamfer the workpiece holes in the fixture 15.

[0061] In a second embodiment of the workpiece internal hole deburring and chip removal equipment, in order to improve the working efficiency of the workpiece internal hole deburring and chip removal equipment, a feeding assembly is further included. The feeding assembly includes a first transfer platform 51 that is slidably connected to the truncated cone 12. The lower side of the first transfer platform 51 is provided with a sliding groove 52 that runs through it from left to right. A crossbar 53 is slidably connected to the sliding groove 52 from left to right. A push plate 54 is slidably connected to the crossbar 53 from top to bottom. The push plate 54 extends to the upper side of the first transfer platform 51. An inclined plate 55 that tilts to the upper right is fixed in the sliding groove 52. The lower side and right side of the push plate 54 are chamfered to form an inclined surface adapted to the inclined plate 55. The assembly also includes a push-pull mechanism for controlling the left and right position of the crossbar 53.

[0062] The push-pull mechanism includes two mounting plates on the machine base 11, with a rotating shaft 61 rotatably connected between the two mounting plates. The machine base 11 is equipped with a No. 3 motor 62 for driving the rotating shaft 61 to rotate. A No. 1 connecting rod 63 is fixed on the rotating shaft 61, and a No. 2 connecting rod 64 is hinged to the end of the No. 1 connecting rod 63. The end of the No. 2 connecting rod 64 is hinged to the left side of the crossbar 53.

[0063] The specific material cutting process is as follows:

[0064] After the workpiece is cleaned and lifted to the top by the clamp 15, several cleaning rods 45 are inserted into the workpiece. Then the support platform 14 and the clamp 15 sink down, while the workpiece remains stationary under the lifting action of the cleaning rods 45, so as to leave space for the first transfer platform 51.

[0065] Then, the third motor 62 is energized and drives the first connecting rod 63 to swing clockwise, causing the second connecting rod 64 to move to the right. During this process, the push plate 54 is in a low position (i.e., the second connecting rod 64 pushes the crossbar 53 and the push plate 54 to move to the right, and the push plate 54, under the action of friction, drives the first transfer platform 51 to move to the right through the inclined plate 55; the push plate 54 will not move upward along the inclined plate 55), and moves to the right along with the first transfer platform 51. When the first transfer platform 51 moves to the far right... When the workpiece is sideways and restricted, the first transfer platform 51 is below the workpiece lifted by the cleaning rod 45. During this process, the upper edge of the push plate 54 is lower than the lower edge of the workpiece. Then the second connecting rod 64 continues to move to the right, and the push plate 54 will rise relative to the first transfer platform 51 under the action of the inclined plate 55, so that the upper edge of the push plate 54 is higher than the bottom surface of the workpiece. Then the cleaning rod 45 retracts to the right, and the workpiece will be prevented from being driven to the right by the push plate 54 and then fall onto the first transfer platform 51.

[0066] Then, the first connecting rod 63 swings counterclockwise, thereby dragging the second connecting rod 64 to the left. During this process, due to the friction between the workpiece and the first transfer platform 51, the first transfer platform 51 also moves to the left. When the first transfer platform 51 is at its left limit, the second connecting rod 64 continues to move to the left, thereby driving the push plate 54 to move to the left relative to the first transfer platform 51. During this process, the push plate 54 will push the workpiece located on the first transfer platform 51 to the left. The machine base 11 is also fixed with a second transfer platform 71. The platform of the second transfer platform 71 is lower on the left and higher on the right, and the right end of the second transfer platform 71 can support the first transfer platform 51. The push plate 54 pushing the workpiece will have the following two situations:

[0067] The workpiece can be pushed by the push plate 54 onto the second transfer platform 71 and slide to the left. The slid-down workpiece can slide onto the conveyor belt (not shown in the figure) for further transfer.

[0068] Because the stroke of the push plate 54 is limited, it stops when the push plate 54 moves to the far left, so that the workpiece slides onto the second transfer table 71 under the action of inertial force.

[0069] The two scenarios described above have different procedures but achieve the same result.

[0070] In addition, the upper sides of both the second transfer platform 71 and the first transfer platform 51 are equipped with two limiting protrusions distributed in the front and back to prevent the workpiece from shifting back and forth.

[0071] After the workpiece is unloaded and the second connecting rod 64 is reset to the left side, the support platform 14 can be reset upwards to facilitate the clamping of the next workpiece.

[0072] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
