Description

Technical Field

[0001] The invention relates to the technical field of steel processing, and in particular to a filtering device used for a water curtain sealing mechanism of a machine tool. Background Art

[0002] The existing equipment used for processing steel parts generally uses grinding machines or ordinary metal polishing machines. The former is suitable for machining small steel parts, and the latter is used for machining large and medium-sized steel parts. In order to prevent the flying dust of cut steel from causing harm to human health and avoid the occurrence of silicosis occupational diseases, machine tools that usually use dry processing use powerful fans to absorb dust, while machine tools that use coolant wet processing often use water curtain sealing devices. Since water curtain sealing can most effectively wet and settle steel dust, its dust prevention effect is better than fan dust collection and is widely used.

[0003] After searching, the Chinese patent application number CN202121794170.3 discloses a water curtain with a filtering and anti-corrosion structure, including a water curtain, a dust filtering mechanism is provided on the right surface of the water curtain, and a water quality filtering mechanism is provided on the upper surface of the water curtain.

[0007] Further: the elliptical motion mechanism includes a secondary gear, a main gear, a limit wheel, a transmission belt and a guide shaft, and a motor is fixed to an outer wall on one side of the bottom of the top frame through a support plate; A main gear, which is arranged at the output end of the motor; Guide shafts, two guide shafts are connected to both sides of the T-shaped fixing plate through bearings.

[0008] Based on the above solution: the secondary gear is arranged at one end of the guide shaft, and the primary gear and the secondary gear are meshed with each other; Limiting wheels, two limiting wheels are respectively sleeved on the middle circumferences of the two guide shafts; The transmission belt is sleeved on the circumference of the two limiting wheels, and the outer side of the transmission belt is connected to the cross slider through bolts.

[0009] A more preferred solution in the aforementioned solution is: the ejection telescopic assembly includes a return spring, a torsion spring and a guide groove; The guide groove is opened in the cross slide block, and L-shaped channels are arranged on both inner sides of the guide groove, and each L-shaped channel forms a sliding fit with the filter strip.

[0010] As a further solution of the present invention: a card receiving assembly is arranged in the guide groove.

[0011] At the same time, the two reset springs are respectively arranged at the bottom of the two L-shaped channels, the top of the reset spring is rotatably connected to the bottom end of the filter strip through a rotating shaft, storage holes are opened on both sides of the top of the cross slider, and a guide cover is fixed on one side of the cross slider close to each storage hole through a torsion spring.

This filtering device for the water curtain sealing mechanism of a machine tool, when working, starts the elliptical motion mechanism to drive the cross slider to move in an elliptical trajectory, and when the cross slider passes through the cross guide hole, the ejection telescopic assembly unfolds its two filter strips and distributes them at the bottom of the top frame, at this time, the water in the water curtain in the top frame, under the push of the filter strips, absorbs the precipitated particles and pushes them from one side to the other side, at this time, the impurity particles fall into the screen of the inclined plate through the leakage hole, and are then filtered and fall into the receiving box, thereby promoting the removal of impurities in the water of the water curtain, ensuring the cleanliness of the water in the water curtain sealing mechanism of the steel processing machine tool, and avoiding the problem of water in the water curtain mixed with steel particles causing the dust collection quality of the water curtain mechanism to decline.

[0016] 2. This filtering device for the water curtain sealing mechanism of a machine tool starts the motor, which drives the main gear to rotate, and drives the guide shaft of the inner ring of the secondary gear to rotate through the meshing relationship.

The cross slider located on the outer side of the transmission belt enters the top frame through the cross guide hole, and its two sides also slide in the sliding holes accordingly, thereby promoting the cross slider to stably circulate in the top frame, ensuring that the water of the water curtain in the top frame continuously removes steel particles efficiently.

[0017] 3. This filtering device used in the water curtain sealing mechanism of a machine tool can effectively pop out the filter strip from the L-shaped channel through a reset spring through a card receiving assembly. At this time, the top end of the filter strip pushes out of the guide cover and is placed inside the top frame, which effectively promotes the moving effect of the filter strip. When the cross slider moves to the bottom of the transmission belt, the filter strip passes through the inclined groove of the guide plate and is retracted into the cross slider. In this way, the cross slider drives the filter strip to circulate through the top frame, thereby improving the cleanliness of the water in the water curtain mechanism.

[0018] 4. A filtering device for a water curtain sealing mechanism of a machine tool. When the cross slider passes through the cross guide hole and the two sides of the top of the cross slider collide with the touch sensor, the touch sensor transmits the touch information to the controller. At this time, the controller controls the start of the electric push rod, and the electric push rod drives the toggle ring to move upward and squeezes the two blocks into the L-shaped channel. At this time, the tightened return spring pops the filter strip out of the cross slider, which effectively improves the continuity of the filter strip's telescopic storage, and further ensures that the filter strip will not collide when it is turned to the bottom of the top frame, thereby protecting the filter strip.

At this time, the water of the water curtain in the top frame 8 is pushed by the filter strips 9 to absorb the precipitated particles and push them from one side to the other side. At this time, the impurity particles fall into the screen 15 of the inclined plate through the leakage hole, and are then filtered and fall into the receiving box 14, thereby promoting the removal of impurities in the water in the water curtain, ensuring the cleanliness of the water in the water curtain sealing mechanism of the steel processing machine tool, and avoiding the problem of water in the water curtain being mixed with steel particles, which causes the dust collection quality of the water curtain mechanism to decline.

The side of the cross slider 16 close to each storage hole is fixed with a guide cover by a torsion spring 19; through the card receiving and receiving assembly, the filter strip 9 can be effectively ejected from the L-shaped channel by the reset spring 17. At this time, the top of the filter strip 9 pushes out the guide cover and is placed inside the top frame 8, which effectively promotes the shifting effect of the filter strip 9. When the cross slider 16 moves to the bottom of the transmission belt 6, the filter strip 9 passes through the inclined groove 12 of the guide plate 2 and retracts the filter strip 9 into the cross slider 16, thereby completing the work of the cross slider 16 driving the filter strip 9 to circulate through the top frame 8, thereby improving the cleanliness of the water in the water curtain mechanism.
