[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] Example 1

[0031] See also Figure 1-7 The present invention provides a drainage device for machining mechanical workpieces, comprising a drainage chamber 1 for machining mechanical workpieces, wherein a foam float 2 movable up and down is arranged inside the drainage chamber 1 for machining mechanical workpieces, and the top of the foam float 2 is arranged in a "concave" shape, and a roller 5 is symmetrically and movably connected inside the top of the foam float 2, wherein one end of one of the rollers 5 is fixedly connected to the output end of the motor 4 through a coupling, and a plurality of transmission belts 7 are sleeved on the outer wall of the roller 5, and a separation ring 6 for limiting the transmission belt 7 is evenly and fixedly connected to the outer wall of the roller 5, and a first mounting plate 3 is symmetrically and fixedly connected inside the top of the foam float 2, and a limiting strip 9 is symmetrically and fixedly connected between the tops of the first mounting plates 3, and conical holes 10 arranged in a conical structure are evenly spaced inside the top of the foam float 2, and the bottom end of the conical hole 10 is connected to the top of the leakage hole 11, and the leakage hole 11 is arranged in the foam At the bottom end of the foam float plate 2, universal wheels 32 are fixedly connected at the four corners of the bottom end of the drainage chamber 1 for processing mechanical workpieces. The motor 4 is a waterproof motor structure. Through the transmission belt 7, during use, the motor 4 drives the roller 5 to rotate forward or reverse at a uniform speed, so that the roller 5 drives all the transmission belts 7 to move, and the forward rotation is connected to the reverse rotation, so that the transmission belt 7 drives the required drainage and cleaned mechanical workpieces to circulate horizontally, so that the mechanical workpiece can be flushed better during the movement of the top end of the transmission belt 7. At the same time, during the movement of the mechanical workpiece, the baffle 8 and the limit strip 9 limit the mechanical workpiece to prevent it from falling. At the same time, the conical hole 10 and the leakage hole 11 are matched, so that the upper wide and lower narrow structure is adopted, which can facilitate the leakage of liquid and prevent the liquid from flowing back to the top of the foam float plate 2 through the conical hole 10.

[0032] Four guide rods 12 are fixedly connected to the bottom end of the drainage chamber 1 for machining mechanical workpieces, and the four guide rods 12 are vertically penetrated inside the through chamber, and the through chamber is vertically penetrated inside the foam float 2, and the inner wall of the through chamber is movably connected with a plurality of balls 14 at equal intervals, and the balls 14 are arranged in a vertical array on the inner wall of the through chamber, and the outer walls of the balls 14 are in conflict with the inner walls of the longitudinal grooves 13, and the longitudinal grooves 13 are evenly spaced on the outer walls of the four guide rods 12. Through the four guide rods 12, when the foam float 2 moves up and down during use, the balls 14 arranged inside the through chamber move inside the longitudinal grooves 13 opened on the outer walls of the guide rods 12, thereby ensuring the stability of the up and down movement of the foam float 2.

[0033] The four corners of the top of the foam floating plate 2 are fixedly connected with a first connecting seat 15, and the top of the first connecting seat 15 is hinged to one end of the first support rod 16. Both ends of the first support rod 16 are provided with a retractable structure. The top of the first support rod 16 is hinged to the bottom end of the second mounting plate 17 through a rotating shaft. The transversely crossed first support rods 16 are connected by a supporting shaft 31. The other end of the supporting shaft 31 is movably connected to the inner side wall of the drainage chamber 1 for mechanical workpiece processing. The top of the second mounting plate 17 is penetrated and fixedly connected with an electromagnet device 18. Through the provided electromagnet device 18, in the process of use, when the foam floating plate 2 is drained by the mechanical workpiece processing When the buoyancy of the liquid at the bottom end of the cavity 1 rises, the first support rod 16 will be driven to move in an arc with the first connecting seat 15 as the base point, and because the first support rod 16 corresponding to the transverse direction is arranged as a cross structure, the second mounting plate 17 will move downward during the process of the foam float 2 rising due to the buoyancy, so that the first support rod 16 will be moved, and its two ends will retract inward and approach each other during the movement, until the magnetic end of the electromagnet device 18 passing through the second mounting plate 17 conflicts with the top of the mechanical workpiece. After the conflict, the motor 4 stops the output operation, and the electromagnet device 18 is energized, and then the top of the mechanical workpiece is magnetically attracted through the magnetic end at the bottom.

[0034] The inner wall of the drainage chamber 1 for machining mechanical workpieces is symmetrically fixedly connected with a second connecting seat 19, and the interior of the second connecting seat 19 is hinged to one end of the second support rod 20 through a movable shaft, and the end of the second support rod 20 away from the second connecting seat 19 is fixedly connected to the outer wall of the transmission pipe 21, and the transmission pipe 21 is set as a hard material structure. The outer wall of the second support rod 20 is hinged to the top of the third support rod 22 through a movable shaft, and the bottom end of the third support rod 22 extends to the inside of the groove, and the groove is opened at the top of the foam floating plate 2, and the end of the third support rod 22 extending to the inside of the groove is hinged to the inner wall of the groove through a movable shaft. A number of flushing nozzles 25 for flushing mechanical workpieces are evenly spaced at the bottom end of the transmission pipe 21. The flushing nozzles 25 are arranged in two groups, and the two groups of flushing nozzles 25 are arranged in a symmetrical inclined structure. One end of the transmission pipe 21 is fixed with a flange A delivery pipe 23 is fixedly connected, and the delivery pipe 23 is set as a soft material structure, and the other end of the delivery pipe 23 is flange-connected to one of the connection ends of the three-way valve 24. Through the set three-way valve 24, the two ends of the three-way valve 24 are respectively flange-connected to the delivery pipe 23, and the other end is connected to the water source. In this way, the three-way valve 24 can transmit water to the delivery pipe 23 and the transmission pipe 21, and then the flushing nozzle 25 is used to achieve cross-flushing of the mechanical workpiece, and with the lifting and lowering movement of the foam float 2, the third support rod 22 will move in an arc with the hinge point inside the groove, so as to be linked to the second support rod 20 to make an arc movement with the second connecting seat 19 as the base point, so that the second support rod 20 drives the transmission pipe 21 to tilt upward, and the angle of the flushing nozzle 25 changes with the movement of the transmission pipe 21, thereby completing the flushing of different areas of the mechanical workpiece.

[0035] A support plate 26 with an inclined structure is fixedly connected between the front and rear outer walls of the mechanical workpiece processing drainage chamber 1, and the support plate 26 is a "concave" structure. The support plate 26 is above the mechanical workpiece processing drainage chamber 1, and the top of the support plate 26 is movably connected to the inside of the movable disk 27, and the bottom of the movable disk 27 is fixedly connected to a control panel 28, and the output end of the control panel 28 is electrically connected to one end of the electric heating rod 29, and the electric heating rod 29 is fixedly connected to the bottom end of the movable disk 27. The electric heating rod 29 is set in a serpentine structure, and the top of the movable disk 27 is internally connected to the inner side of the movable disk 27. A heat conducting plate 30 is fixedly connected at a distance, and a movable disk 27 is set so that the movable disk 27 can move horizontally along the outer wall of the support plate 26 until it is under the workpiece. In this way, after the electromagnet device 18 is powered off, the mechanical workpiece is picked up, and the heating rod 29 is heated up through the control panel 28. The heat conducting plate 30 then conducts the heat energy generated by the heating rod 29 to quickly heat up the movable disk 27, thereby heating the mechanical workpiece stored inside the top of the movable disk 27, and then evaporating the liquid attached to the mechanical workpiece, thereby completely removing the moisture.

[0036] The specific use process of this embodiment is as follows:

[0037] First, the water in the drainage chamber 1 for machining the mechanical workpiece is drained by a water pump. At this time, the foam float 2 is located at the bottom of the drainage chamber 1 for machining the mechanical workpiece. Then, the machined workpiece is placed on the transmission belt 7. The three-way valve 24 is connected to an external water pipe and a pressure pump to facilitate water to enter the transmission pipe 21 through the delivery pipe 23. Then, the water can be sprayed from the inclined flushing nozzle 25 to the workpiece below, so as to flush the workpiece.

[0038] Secondly, the motor 4 is controlled to start the driving roller 5 to rotate, and the roller 5 can drive the transmission belt 7 to operate. The operation of the transmission belt 7 drives the workpiece to circulate. The baffle 8 prevents the workpiece from falling to both sides. The limit strip 9 blocks the workpiece driven by the transmission belt 7. The flushed water falls into the inner bottom of the foam float 2 through the gap between the transmission belts 7, and then leaks into the drainage chamber 1 for mechanical workpiece processing through the tapered hole 10 and the leakage hole 11. The water level in the drainage chamber 1 for mechanical workpiece processing rises and can push the foam float 2 up. When the foam float 2 rises, the third support rod 22 pushes the second support rod 20, so that the second support rod 20 can make an upward tilting movement with the second connecting seat 19 as the base point, thereby driving the transmission pipe 21 to move out from between the foam float 2 and the second mounting plate 17 to avoid affecting the electromagnet device 18 to adsorb the workpiece;

[0039] Then, when the second support rod 20 makes an upward tilting movement with the second connecting seat 19 as the base point, the angles of the two symmetrical groups of flushing nozzles 25 will change accordingly, and the flushing on both sides can be changed into cross flushing, so that during the rising process of the foam float 2, the flushing nozzles 25 can always flush the workpieces on the transmission belt 7, and through the cross-arranged first support rods 16, the foam float 2 rises and the second mounting plate 17 moves down, and at the same time, both ends of the first support rods 16 move inside, so that the foam float 2 and the second mounting plate 17 are close to each other, and then the electromagnet device 18 is controlled to start, and after being energized, the bottom can generate magnetic attraction, so as to adsorb the workpiece on the lower transmission belt 7, and before adsorption, the control motor 4 is stopped, and then the water in the drainage chamber 1 for mechanical workpiece processing is pumped out again by using an external water pump, so that the foam float 2 moves down and resets, and then drives the second mounting plate 17 and the electromagnet device 18 to move up and reset;

[0040] Finally, the movable plate 27 is pushed to slide horizontally along the support plate 26 to the bottom of the electromagnet device 18, so that when the electromagnet device 18 is turned off, the movable plate 27 can receive the fallen workpiece, and then the control panel 28 controls the electric heating rod 29 to be energized to increase the temperature. Through the heat conduction of the heat conducting plate 30, the movable plate 27 can be quickly heated, and then the workpiece will also be heated. The water on the surface of the workpiece will evaporate due to the temperature increase of the workpiece itself, so as to completely remove the moisture. In this way, a drainage device for mechanical workpiece processing is completed;
