The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to 9, the present invention provides a multi-station numerical control double-sided milling machine, which has the following technical scheme:

a multi-station numerical control double-sided milling machine comprises a workbench 1, wherein two first supports 2 are vertically and symmetrically and fixedly arranged on the left side and the right side of the top wall of the workbench 1, electric slide rails 3 are fixedly arranged on the side walls, far away from each other, of the two first supports 2, sliders 4 are movably arranged on the two electric slide rails 3 respectively, first telescopic rods 5 are horizontally and fixedly arranged on the side walls, near the two sliders 4, of the side walls, an electric tool bit 6 is horizontally and fixedly arranged on the output end of the first telescopic rods 5, a second support 7 is fixedly arranged on the top wall of the workbench 1, a mounting rod 8 is vertically and movably arranged on the second support 7, a second telescopic rod 9 for driving the mounting rod 8 to move up and down along the second support 7 is fixedly arranged on the side wall of the workbench 1, a mounting sleeve 10 is fixedly arranged on the outer wall of the electric tool bit 6, a dust cover 11 and a first spring 12 which can be inserted into the mounting sleeve 10 are movably sleeved on the outer wall of the electric tool bit 6, two ends of the first spring 12 are respectively fixedly connected with the mounting sleeve 10 and the dust cover 11, and the workbench 1 is provided with a collecting mechanism matched with the dust cover 11.

When a workpiece needs to be polished, the workpiece is fixedly arranged on two sides of the mounting rod 8, and then the power is switched on, so that the first telescopic rod 5, the second telescopic rod 9, the electric sliding rail 3 and the electric tool bit 6 start to work, and the workpiece is polished.

In the initial state, under the action of the first spring 12, the electric cutter head 6 is located inside the dust cover 11, in the working process, the first telescopic rod 5 drives the electric cutter head 6 to be close to the workpiece, so that the edge of the dust cover 11 is firstly attached to the edge of the workpiece, the first telescopic rod 5 continues to extend, under the action of the first spring 12, the dust cover 11 is retracted into the mounting sleeve 10, and therefore the electric cutter head 6 is in contact with the surface of the workpiece, so that the workpiece is polished, chips falling from the workpiece in the polishing process fall onto the inner bottom wall of the dust cover 11 under the action of gravity, when the chips are in contact with the electric cutter head 6 rotating at a high speed, according to the law of conservation of kinetic energy, the kinetic energy of the electric cutter head 6 is transmitted to the chips, so that the chips can splash around, therefore, the dust cover 11 mounted on the electric cutter head 6 plays a role of preventing the chips from splashing around, and the debris on the bottom wall of the debris dust cover 11 will be collected by the collection mechanism.

Referring to fig. 1, 2 and 4, as an embodiment of the present invention, the collecting mechanism includes a collecting box 13 fixedly mounted on the bottom wall of the workbench 1, a mounting opening is formed on the top wall of the workbench 1, a funnel 14 communicated with the collecting box 13 is fixedly mounted in the mounting opening, a conduit 15 extending above the funnel 14 is fixedly mounted on the inner bottom wall of the dust cover 11, and a cooling mechanism matched with the dust cover 11 is arranged on the second bracket 7.

When the splashed debris strikes the inner wall of the dust cover 11, the kinetic energy of the debris is transferred to the dust cover 11 according to the law of conservation of kinetic energy, the dust cover 11 does not move due to the large mass of the dust cover 11, but the debris freely falls onto the inner bottom wall of the dust cover 11 after the momentum transfer of the debris, since the guide tube 15 extending above the funnel 14 is fixedly installed on the inner bottom wall of the dust cover 11, the debris falling onto the inner bottom wall of the dust cover 11 passes through the guide tube 15 and falls onto the surface of the funnel 14, and since the inner wall of the funnel 14 is inclined, the debris slides down along the inner wall of the funnel 14 to the collection box 13, the effect of collecting the debris is achieved in the process, since the electric cutter head 6 grinds the workpiece by means of the friction force between the cutter head and the workpiece, the temperature of the workpiece rises during the work, and since the workpiece made of metal is easily deformed after the temperature rises, therefore, the surface of the workpiece can be rapidly cooled under the action of the cooling mechanism, so that the effect of preventing splashed chips from contacting with the surface of the workpiece to cause the surface of the workpiece to be scratched is achieved.

As an embodiment of the present invention, referring to fig. 2, 6 and 7, the cooling mechanism includes an air bottle 16 fixedly mounted on the top wall of the second support 7, an air hole is opened on the air bottle 16, a first pressure plate 17 made of magnetic material is movably disposed in the air bottle 16, a second spring 18 is horizontally and fixedly mounted between the side wall of the first pressure plate 17 and the inner wall of the air bottle 16, a power supply wire of the electric tool bit 6 is wound into a first coil 19, the first coil 19 is fixedly mounted on the inner wall of one end of the air bottle 16 far away from the second spring 18, a telescopic exhaust pipe 20 communicated with the air bottle 16 is fixedly mounted on the inner top wall of the dust cover 11, and an inflating mechanism matched with the air bottle 16 is disposed on the workbench 1.

In the initial state, the first pressure plate 17 moves to the end far away from the first coil 19 under the action of the second spring 18, and air can be absorbed from the outside through the exhaust pipe 20, so that the gas cylinder 16 is filled with gas, the electric cutter head 6 is electrified during operation, current passes through the first coil 19, so that a magnetic field which is mutually attracted with the first pressure plate 17 is generated around the first coil 19, the first pressure plate 17 moves along the inner wall of the gas cylinder 16 under the action of the magnetic field, the air in the gas cylinder 16 is squeezed during the movement of the first pressure plate 17, the pressure in the gas cylinder 16 is increased, and the air in the gas cylinder 16 enters the dust cover 11 along the exhaust pipe 20.

When the cutter head 6 works fast, under the action of the inflating mechanism, the gas content in the gas cylinder 16 will increase fast, resulting in the increase of the pressure in the gas cylinder 16, at this time, the pressing plate 17 will move towards the direction away from the coil 19 under the combined action of the gas pressure and the pulling force of the second spring 18 and be released outwards through the gas hole, when the pressing plate 17 passes through the gas hole, the redundant gas of the gas will be discharged from the gas hole, thus playing a role in preventing the exhaust pipe 20 from bursting.

Because the conduit 15 is installed on the bottom wall of the dust cover 11, the gas entering the dust cover 11 can be rapidly exhausted, so that the gas in the gas cylinder 16 can continuously enter the dust cover 11, the gas can be contacted with a workpiece when passing through the dust cover 11, and because the temperature of the air is lower than that of the workpiece, heat exchange is generated between the workpiece and the air in the contact process, so that the workpiece is cooled, and under the action of the inflating mechanism, the gas cylinder 16 can continuously exhaust the gas into the dust cover 11, so that the workpiece is continuously cooled.

When the machining is completed, the current in the coil 19 disappears, and therefore the attraction force to the pressing plate 17 is lost, at which point the pressing plate 17 is restored by the second spring 18, thereby being ready for the next work.

Under the action of the driving mechanism, the first piston plate 23 and the second piston plate 24 move along the first cylinder 21 and the second cylinder 22, since both the first cylinder 21 and the second cylinder 22 can only draw air from the outside through the first check valve 29 by the second check valve 31, and the gas in the first cylinder 21 and the second cylinder 22 can be discharged into the gas cylinder 16 only through the gas inlet pipe 30 under the action of the first check valve 29, thus as the first piston plate 23 moves up the first cylinder 21, the pressure in the first cavity 25 increases, at which point, under the action of the first one-way valve 29, gas in the first cavity 25 can only pass through the second one-way valve 31 and the inlet tube 30 into the gas cylinder 16, and the pressure in the second cavity 26 decreases as the first piston plate 23 moves up along the inner wall of the first cylinder 21, the second cavity 26 can only absorb gas from the outside through the first check valve 29 under the action of the second check valve 31 to balance the pressure; when the first piston plate 23 moves down along the inner wall of the first cylinder 21, the pressure in the gas-filled second cavity 26 increases, so that the gas in the second cavity 26 can only enter the gas cylinder 16 through the second check valve 31 and the gas inlet pipe 30 under the action of the first check valve 29, and the first cavity 25 is in a negative pressure state in the process, so that the first cavity 25 absorbs air from the outside through the first check valve 29 under the action of the second check valve 31; similarly, when the second piston plate 24 moves to the left along the inner wall of the second cylinder 22, the pressure in the third cavity 27 increases, so that the air in the third cavity 27 will enter the cylinder 16 and the fourth cavity 28 will absorb air from the outside under the action of the first check valve 29 and the second check valve 31, and when the second piston plate 24 moves to the right along the inner wall of the second cylinder 22, the air in the fourth cavity 28 will enter the cylinder 16 and the third cavity 27 will absorb air from the outside, which plays a role in supplementing the cylinder 16 with air in the whole process.

Referring to fig. 4, as an embodiment of the present invention, a hydraulic rod 36 is horizontally and fixedly installed on an inner side wall of the collection box 13, a second pressing plate 37 is vertically and fixedly installed on an output end of the hydraulic rod 36, an edge of the second pressing plate 37 is attached to the inner wall of the collection box 13, and a trigger mechanism matched with the hydraulic rod 36 is arranged in the collection box 13.

In the working process, the fragments falling from the discharge port of the funnel 14 are accumulated right below the discharge port, when a large amount of fragments are accumulated below the discharge port, the trigger mechanism starts to work, the hydraulic rod 36 starts to extend and drives the second pressing plate 37 to move along the inner wall of the collection box 13 under the action of the trigger mechanism, so that the second pressing plate 37 pushes the fragments scattered on the inner bottom wall of the collection box 13 to move along the inner bottom wall of the collection box 13, the fragments accumulated right below the discharge port of the funnel 14 are pushed away from the position, the blockage of the funnel 14 caused by the accumulation of the fragments is prevented, and the function of ensuring that the fragments can normally enter the collection box 13 is realized.

Referring to fig. 4, as an embodiment of the present invention, the trigger mechanism includes a mounting box 38 fixedly mounted on the bottom wall of the collecting box 13 and communicated with the collecting box 13, a supporting plate 39 is movably disposed in the mounting box 38, a third spring 40 is fixedly mounted between the bottom wall of the supporting plate 39 and the inner bottom wall of the mounting box 38, a switch 41 connected in series with the hydraulic rod 36 is fixedly mounted on the inner wall of the mounting box 38, a pressing rod 42 extending to the outside of the collecting box 13 is horizontally and fixedly mounted on the side wall of the second pressing plate 37 close to the hydraulic rod 36, and a material blocking mechanism matched with the pressing plate is disposed on the collecting box 13.

In an initial state, the bottom wall of the supporting plate 39 is attached to the top wall of the mounting box 38 under the action of the third spring 40, in a working process, the scraps fall to a position in the collection box 13 right below the discharge port and are accumulated, so that the pressure applied to the supporting plate 39 is gradually increased, the supporting plate 39 gradually moves downwards along the inner wall of the mounting box 38, along with the downward movement of the supporting plate 39, when the top wall of the supporting plate 39 and the top wall of the mounting box 38 are on the same horizontal plane, the switch 41 is pressed, and at the moment, the hydraulic rod 36 starts to work, so that the hydraulic rod 36 is triggered to work; and in the process that hydraulic stem 36 drove second clamp plate 37 and removes, second clamp plate 37 drives depression bar 42 and moves together, therefore depression bar 42 will be fixed backup pad 39 in mounting box 38 all the time, backup pad 39 shifts up after can preventing the piece on backup pad 39 surface from being shifted, the effect that prevents that second clamp plate 37 can't reset has been played, and under the effect of putty mechanism, can prevent that the piece from getting into the space of installing hydraulic stem 36 one side in collecting tank 13 when hydraulic stem 36 during operation, play and prevent that the piece from contacting with hydraulic stem 36 and leading to the impaired effect of hydraulic stem 36 when dropping.

Referring to fig. 4 and 5, as an embodiment of the present invention, the blocking mechanism includes a first mounting groove 43 and a second mounting groove 44 formed in the funnel 14, a baffle 45 made of a magnetic material and matched with the discharge port of the funnel 14 is movably disposed in the first mounting groove 43, an elastic cord 46 is fixedly mounted between the baffle 45 and the first mounting groove 43, and a power supply wire of the hydraulic rod 36 is wound into a second coil 47 and fixedly mounted in the second mounting groove 44.

In the initial state, the baffle 45 retracts into the first mounting groove 43 under the action of the elastic rope 46, when the switch 41 is pressed, current passes through the second coil 47, a magnetic field which is mutually attracted with the baffle 45 is generated around the coil, and under the action of the magnetic field, the baffle 45 moves along the first mounting groove 43 and is gradually inserted into the second mounting groove 44, so that the discharge hole of the funnel 14 is blocked, and the function of preventing the fragments from continuously falling into the collection box 13 is achieved.

The working principle is as follows: when a workpiece needs to be polished, the workpiece is fixedly arranged on two sides of the mounting rod 8, and then the power is switched on, so that the first telescopic rod 5, the second telescopic rod 9, the electric sliding rail 3 and the electric tool bit 6 start to work, and the workpiece is polished.

In an initial state, under the action of the first spring 12, the electric cutter head 6 is located inside the dust cover 11, in a working process, the first telescopic rod 5 drives the electric cutter head 6 to be close to a workpiece, so that the edge of the dust cover 11 is firstly attached to the edge of the workpiece, the first telescopic rod 5 continues to extend, under the action of the first spring 12, the dust cover 11 is retracted into the mounting sleeve 10, and therefore the electric cutter head 6 is in contact with the surface of the workpiece, so that the workpiece is polished, chips falling from the workpiece in the polishing process fall onto the inner bottom wall of the dust cover 11 under the action of gravity, when the chips are in contact with the electric cutter head 6 rotating at a high speed, according to the law of conservation of kinetic energy, the kinetic energy of the electric cutter head 6 is transmitted to the chips, so that the chips can splash around, therefore, the dust cover 11 mounted on the electric cutter head 6 plays a role of preventing the chips from splashing around, and when the splashed debris strikes the inner wall of the dust cover 11, the kinetic energy of the debris can be transferred to the dust cover 11 according to the law of conservation of kinetic energy, the dust cover 11 cannot move due to the large mass of the dust cover 11, but the debris can freely fall onto the inner bottom wall of the dust cover 11 after the momentum of the debris is transferred, the conduit 15 extending above the funnel 14 is fixedly mounted on the inner bottom wall of the dust cover 11, so that the debris falling onto the inner bottom wall of the dust cover 11 can pass through the conduit 15 and fall onto the surface of the funnel 14, and the debris can slide down along the inner wall of the funnel 14 to the collecting box 13 due to the inclination of the inner wall of the funnel 14, so that the effect of collecting the debris is realized in the process.

Because the electric tool bit 6 grinds the workpiece by means of the friction force between the tool bit and the workpiece, therefore, the temperature of the workpiece can be increased in the working process, and because the workpiece made of metal materials is easy to deform after the temperature is increased, in the initial state, the first pressure plate 17 is moved to an end remote from the first coil 19 by the second spring 18, and is capable of absorbing air from the outside through the exhaust pipe 20, filling the gas cylinder 16 with gas, during operation, the electric cutter head 6 is powered on, and current passes through the first coil 19, so that a magnetic field which is mutually attracted with the first pressure plate 17 is generated around the first coil 19, the first pressure plate 17 will move along the inner wall of the gas cylinder 16 under the influence of the magnetic field and, during the movement of the first pressure plate 17, the air in the cylinder 16 will be compressed and the pressure inside the cylinder 16 will increase, so that the air in the cylinder 16 will enter the dust cap 11 along the vent tube 20.

Because the bottom wall of the dust cover 11 is provided with the conduit 15, the gas entering the dust cover 11 can be rapidly exhausted, so that the gas in the gas cylinder 16 can continuously enter the dust cover 11 and can be contacted with the workpiece when passing through the dust cover 11, and because the temperature of the air is lower than that of the workpiece, heat exchange is generated between the workpiece and the air in the contact process, so that the workpiece is cooled.

So that when the first and second piston plates 23 and 24 are moved along the first and second cylinders 21 and 22 respectively, since both the first cylinder 21 and the second cylinder 22 can only draw air from the outside through the first check valve 29 by the second check valve 31, and the gas in the first cylinder 21 and the second cylinder 22 can be discharged into the gas cylinder 16 only through the gas inlet pipe 30 under the action of the first check valve 29, thus as the first piston plate 23 moves up the first cylinder 21, the pressure in the first cavity 25 increases, at which point, under the action of the first one-way valve 29, gas in the first cavity 25 can only pass through the second one-way valve 31 and the inlet tube 30 into the gas cylinder 16, and the pressure in the second cavity 26 decreases as the first piston plate 23 moves up along the inner wall of the first cylinder 21, the second cavity 26 can only absorb gas from the outside through the first check valve 29 under the action of the second check valve 31 to balance the pressure; when the first piston plate 23 moves down along the inner wall of the first cylinder 21, the pressure in the gas-filled second cavity 26 increases, so that the gas in the second cavity 26 can only enter the gas cylinder 16 through the second check valve 31 and the gas inlet pipe 30 under the action of the first check valve 29, and the first cavity 25 is in a negative pressure state in the process, so that the first cavity 25 absorbs air from the outside through the first check valve 29 under the action of the second check valve 31; similarly, when the second piston plate 24 moves leftwards along the inner wall of the second cylinder 22, the pressure in the third cavity 27 increases, so that the gas in the third cavity 27 enters the gas cylinder 16 under the action of the first check valve 29 and the second check valve 31, and the fourth cavity 28 absorbs air from the outside, and when the second piston plate 24 moves rightwards along the inner wall of the second cylinder 22, the air in the fourth cavity 28 enters the gas cylinder 16, and the third cavity 27 absorbs air from the outside, so that the gas cylinder 16 can be continuously exhausted into the dust cover 11 in the whole process, and the workpiece can be continuously cooled, and the workpiece surface can be rapidly cooled, and the effect of preventing splashed chips from being scraped due to the contact with the workpiece surface is achieved.

The hydraulic rod 36 starts to extend and drives the second pressing plate 37 to move along the inner wall of the collection box 13, so that the second pressing plate 37 pushes the debris scattered on the inner bottom wall of the collection box 13 to move along the inner bottom wall of the collection box 13, so that the debris accumulated right below the discharge hole of the hopper 14 is pushed away from the position, thereby preventing the debris from accumulating to cause the hopper 14 to be blocked, and playing a role in ensuring that the debris can normally enter the collection box 13.

And in the initial state, the baffle 45 retracts into the first mounting groove 43 under the action of the elastic rope 46, when the switch 41 is pressed, current passes through the second coil 47, a magnetic field which is mutually attracted with the baffle 45 is generated around the coil, and under the action of the magnetic field, the baffle 45 moves along the first mounting groove 43 and is gradually inserted into the second mounting groove 44, so that the discharge hole of the funnel 14 is blocked, and the function of preventing the fragments from continuously falling into the collection box 13 is achieved.
