Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic water outlet, in particular to a hydraulic water outlet device for a machining center. Background Art

[0002] Spindle center water discharge involves pressurized coolant being delivered directly through the spindle to the tool's cutting surface. This not only cools the tool immediately but also effectively flushes away milled chips. In common equipment, water storage tanks recycle and reuse water. Therefore, the recycled water often contains residual particles, necessitating filtration before it is delivered again.

[0003] When filtering water with existing technology, with long-term use, too much residue accumulates. If it cannot be collected in time, the water output of the filter structure will be greatly reduced and the internal water pressure will increase, which will not only affect the normal use of the equipment, but also cause the water pressure to damage the filter structure and cause it to deform. The existing treatment method requires manual shutdown to replace the filter structure. Summary of the Invention

DETAILED DESCRIPTION

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0035] See also Figure 1-3 A hydraulic water outlet device for a machining center includes a centrifugal pump 1 and a water tank housing 2. The centrifugal pump 1 is installed on the top of the water tank housing 2, and the bottom thereof penetrates into the interior of the water tank housing 2. A water outlet box 3 is provided on the water tank housing 2. The inlet end of the water outlet box 3 is connected to the outlet end of the centrifugal pump 1 and is used to cool the cutting tool of the cutting equipment. A filter box 6 is further provided on the top of the water tank housing 2. A cover plate is provided on the top of the filter box 4. A filter component 5 is provided inside the filter box 4. The filter component 5 includes a truncated cone-shaped filter screen 51 and a slag storage pipe 52 provided at the bottom of the filter screen 51.

[0036] A slag cleaning component 6 is provided at the bottom of the filter screen 51, and the slag cleaning component 6 includes a cleaning funnel 61. The cleaning funnel 61 is provided with multiple cleaning parts 62, and the cleaning parts 62 correspond one-to-one to the mesh holes of the filter screen 51; an opening and closing component 7 is provided inside the slag storage pipe 52, and a driving component 8 is provided on the cleaning funnel 61. The driving component 8 is responsible for driving the cleaning funnel 61 to rise at a set time, cleaning the filter screen 51, and discharging the sewage through the opening and closing component 7.

[0037] Specifically, the cleaning member 62 is a rod with a needle-shaped structure, and the rod corresponds to the meshes of the filter 51 one by one.

[0038] See also Figure 5 A cleaning component 9 is provided on the filter screen 51, and the cleaning component 9 includes a reduction motor 91 provided on the top of the cover plate 12. The output end of the reduction motor 91 is fixedly connected to a drive shaft 92, and the outer wall of the drive shaft 92 is fixedly connected to a linkage rod 93. The end of the linkage rod 93 is fixedly connected to a cleaning brush 94. The cleaning brush 94 is a hard bristle brush, which serves to clean the impurity particles on the upper surface of the filter screen 51 into the inside of the slag storage pipe 52.

[0039] Initially, when the device is used, since water is reused, the returned liquid may contain impurity particles. Therefore, each time the centrifugal pump 1 is used to start conveying water, the reduction motor 91 is turned on at the same time. The reduction motor 91 slowly rotates with the cleaning brush 94 through the drive shaft 92 and the linkage rod 93, and the cleaned residue rolls into the residue storage pipe 52, which can not only effectively clean the filter screen 51, but also collect the residue in time.

[0040] See also Figure 4 In an embodiment further provided by the present invention, the cleaning funnel 61 is slidably connected to the inner wall of the filter box 4, the filter screen 51 is fixedly connected to the inner wall of the filter box 4, and a plurality of water outlet holes 63 are provided on the cleaning funnel 61. Initially, the liquid is filtered by the filter screen 51 and falls through the water outlet holes 63.

[0041] Specifically, a slider 65 is fixedly connected to the outer end of the cleaning funnel 61 , a limit bar 64 is fixedly connected to the inner wall of the filter box 4 , and the slider 65 slides in the limit bar 64 .

[0042] The water outlet holes 63 on the cleaning funnel 61 are evenly distributed, covering the entire cleaning funnel 61, and are staggered with the cleaning parts 62 so that the water output remains at a normal level.

[0043] When the entire filter screen 51 needs to be thoroughly cleaned, the cleaning funnel 61 can be lifted, and the cleaning piece 62 can enter the corresponding mesh to push out the residue that accidentally falls on the mesh (some residue is stuck on the mesh and it is difficult for the cleaning brush 94 to clean it). The pushed-out particles fall on the residue storage pipe 52 with the water flow and are subsequently discharged out of the filter box 4.

[0044] See also Figure 6-8 In an embodiment further provided by the present invention, the driving component 8 includes a special-shaped ring 81 fixedly connected to the bottom of the cleaning funnel 61, and the special-shaped ring 81 is provided with a crest portion 811 and a trough portion 812, and the surface is a smooth curved surface mechanism. A driving ring 82 is provided below the special-shaped ring 81, and a push rod 83 is fixedly connected to the top of the driving ring 82. The push rod 83 drives the cleaning funnel 61 to rise by rotation.

[0045] The slag storage pipe 52 includes a first pipe body 521, a second pipe body 522 and a third pipe body 523. The bottom surface of the first pipe body 521 and the top surface of the third pipe body 523 are both provided with an annular groove, and the second pipe body 522 is slidably connected to the annular groove.

[0046] The outer wall of the second tube body 522 is fixedly connected to the inner wall of the drive ring 82, and a transmission component 10 is provided inside the second tube body 522. The transmission component 10 includes a first fitting ring 101 fixedly connected to the inner wall of the first tube body 521 and a second fitting ring 102 fixedly connected to the inner wall of the second tube body 522. The first fitting ring 101 is provided with a transmission hole 103 (the diameter is much larger than the outer diameter of the impurity particles), and the top surface of the second fitting ring 102 is fixedly connected to a plurality of transmission rods 104. A plurality of connecting rods 105 are fixedly connected between the first tube body 521 and the drive shaft 92. The second fitting ring 102 is provided with a lifting component 11. The lifting component 11 is responsible for pulling the transmission rod 104 up at a set time so that the second tube body 522 rotates following the first tube body 521.

[0047] The opening and closing component 7 includes a first notch plate 71 and a second notch plate 72. The first notch plate 71 and the second notch plate 72 are both provided with a water outlet notch (the size of which is set according to actual needs). A telescopic rod 73 is provided between the second notch plate 72 and the second fitting ring 102. When the top rod 83 rotates, the second notch plate 72 also rotates at the same time.

[0048] Specifically, the transmission rod 104 adopts a telescopic structure and is provided with a spring inside. When the transmission rod 104 is not aligned with the transmission hole 103, it can first contract until it is aligned with the transmission hole 103; the transmission rod 104 includes a thick rod and a thin rod slidably connected to the inside of the thick rod, and the spring connects the bottom of the thin rod to the inner bottom of the thick rod. The radii of the thick rod and the thin rod are both smaller than the transmission hole 103; the number of transmission holes 103 can be more than the transmission rod 104.

[0049] During the rotation of the driving shaft 92 , the first tube body 521 is rotated via the connecting rod 105 , and the first tube body 521 rotates slowly with the first engagement ring 101 .

[0050] When the second engaging ring 102 rises, the transmission rod 104 also rises. After the transmission rod 104 enters the transmission hole 103, the second engaging ring 102 rotates together with the first engaging ring 101. At this time, the driving ring 82 outside the second tube body 522 rotates accordingly. Initially, the push rod 83 is located at the crest of the wave. When the push rod 83 starts to rotate 90 degrees, the cleaning funnel 61 is driven to rise to the first height. At this time, the cleaning parts 62 all enter the mesh of the filter 51, push out the residue in the mesh, and complete the thorough cleaning of the filter 51; when the push rod 83 continues to rotate 90 degrees, it drives the cleaning funnel 61 to rise to the second height. At this time, the cleaning funnel 61 rises to the highest point, and the cleaning funnel 61 is also completely fitted with the filter 51; after continuing to rotate 180 degrees, the cleaning funnel 61 moves under the action of its own gravity and finally moves to the initial position.

[0051] When the push rod 83 rotates 90 degrees, the second notch plate 72 begins to be offset from the notch of the first notch plate 71, and the liquid above mixed with impurities falls from the slag storage pipe 52. When the push rod 83 continues to rotate 180 degrees, the gap between the second notch plate 72 and the first notch plate 71 is the largest. Finally, when the push rod 83 rotates 360 degrees, the second notch plate 72 and the first notch plate 71 complete the blocking of the slag storage pipe 52.

[0052] See also Figure 9-10 The lifting component 11 includes a traction member 111 connected to the second fitting ring 102, and the cover plate 12 is rotatably connected to an annular baffle 112. The inner wall of the annular baffle 112 is slidably connected to a pressure plate 113. The pressure plate 113 rises when the water pressure reaches a set value, and pulls the transmission rod 104 to rise through the traction member 111.

[0053] The bottom surface of the annular baffle 112 is fixedly connected to a first magnetic ring 114 , and the bottom surface of the pressure plate 113 is embedded with a second magnetic ring 115 . Initially, the first magnetic ring 114 and the second magnetic ring 115 attract each other (the magnetic force is 2-10 Newtons), and a reset member 116 is provided between the cover plate 12 and the pressure plate 113 .

[0054] The pressure plate 113 is slidably connected to the outer wall of the drive shaft 92, and the outer wall of the drive shaft 92 is fixedly connected with a guide bar. A sliding bar is provided on the inner side of the pressure plate 113, and the sliding bar slides on the outside of the guide bar, so that the drive shaft 92 can both rotate with the pressure plate 113 and slide on it.

[0055] Specifically, a top ring is fixedly sleeved on the drive shaft 92 , and the reset member 116 is sleeved on the drive shaft 92 . One end of the reset member 116 is fixedly connected to the top ring, and the other end is fixedly connected to the pressure plate 113 . The reset member 116 is a reset spring.

[0056] Because the filter 51 is used for a long time, which may be several days or even several weeks according to actual needs, the impurities remaining on the filter 51 will block the mesh, and some of the residue accumulated in the slag storage tube 52 will overflow and be distributed in the lower layer of the filter 51 under the action of buoyancy, which will eventually lead to too few exposed meshes on the filter 51, greatly reducing the water output, and ultimately making the water intake greater than the water output. The water pressure in the chamber above the filter 51 is too high, and under the action of the water pressure, the first magnetic ring 114 and the second magnetic ring 115 separate (the water pressure exceeds the magnetic force between the two), and then the pressure plate 113 moves upward, pulling the second fitting ring 102 up through the traction member 111, completing the synchronous rotation of the first fitting ring 101 and the second fitting ring 102.

[0057] When the water outlet formed by the first notch plate 71 and the second notch plate 72 is at its maximum, the water inflow is greater than the water outflow, that is, the water pressure is still relatively high at this time, and the pressing plate 113 will not rebound.

[0058] When the cleaning funnel 61 slides down, the residues in the filter screen 51 and the residue storage pipe 52 are discharged outside the filter box 4. At this time, the water pressure on the filter screen 51 is normal, and the pressure plate 113 will return to its initial position under the action of the reset member 116.

[0059] In a solution further provided by the present invention, the drive shaft 92, the linkage rod 93, the connecting rod 105 and the traction member 111 all rotate synchronously, so there is no motion interference.

[0060] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
