Description

Technical Field

[0001] This utility model relates to a chip flushing device, and more particularly to a chip flushing device for a machining center, belonging to the field of machining technology. Background Technology

[0002] In the prior art, such as the utility model application with application number 201920538023.6, a chip flushing device for a machining center is disclosed. Through the setting of a slag discharge screw, the chips generated during machining are blown off the surface of the product by gas generated by an air pump, scattering inside the worktable or machine tool slot. The chips on the worktable surface are pushed into the slag discharge screw slot by the operator. The chips in the machine tool slot are flushed into the slag discharge screw slot by a liquid pump, which draws flushing liquid from the storage tank. A motor starts the slag discharge screw, causing it to rotate and roll up the chips. The chips fall into the waste slag trough and then into the screen drawer, making it easy to wash and clean the chips. The chips that fall into the screen drawer are also easy to clean, thus achieving the purpose of convenient washing and cleaning of chips. With the air pump, the air pump generates gas and delivers it through the air pipe to the bamboo-shaped plastic tube, which accelerates the air flow speed at the cutter head, making it easier to cool the cutter head. The air force also blows away the chips on the product surface, preventing the chips from accumulating and affecting the processing, thus achieving the purpose of cooling the cutter head and blowing away the chips.

[0003] The above-mentioned applications still have shortcomings:

[0004] The chips and rinsing fluid flushed by this type of machining center chip flushing device are pushed into the screen drawer through the slag discharge screw. Over time, the chips accumulate in the screen drawer. If the chips are not processed in time, the impurities in the screen drawer will clog the mesh and cause water accumulation. This will prevent the rinsing fluid from flowing back to the storage tank in time, which may cause water to accumulate in the waste tank or even overflow onto the machine tool worktable, and will also affect the use of the rinsing fluid.

[0005] To address this issue, a chip flushing device for machining centers was designed. Utility Model Content

[0006] The main purpose of this invention is to provide a chip flushing device for machining centers to solve the problems mentioned in the background art.

[0032] Example 1

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a chip flushing device for a machining center, including a body 1, a return groove 2 installed on the bottom wall of the body 1, a flushing mechanism 13 provided between the return groove 2 and the body 1, a waste trough 3 fixed inside the body 1, guide plates 4 symmetrically arranged on the top of the waste trough 3, a motor 5 symmetrically installed on one side of the body 1, a slag discharge screw 6 fixed on the output shaft of the motor 5, and the slag discharge screw 6 penetrates into the waste trough 3. A sealing ring is provided at the penetration point between the slag discharge screw 6 and the body 1. The sealing ring is a high-temperature resistant and wear-resistant rubber sealing ring.

[0034] A cleaning mechanism 7 is provided between the slag discharge screw 6 and the machine body 1. A screen frame 8 is fixed to the bottom of one end of the waste trough 3. The screen frame 8 adopts a detachable structure. When the mesh is blocked, it can be quickly disassembled for cleaning. Hydraulic cylinders 9 are symmetrically installed inside the machine body 1. The hydraulic cylinders 9 are installed inside the machine body 1 through the mounting base. The mounting base of the hydraulic cylinder 9 adopts an L-shaped metal bracket. One side of the bracket is fixed to the inner wall of the machine body 1 by bolts. The other side is provided with an arc-shaped groove that matches the outer diameter of the hydraulic cylinder 9. A shock-absorbing rubber sleeve is installed in the groove. The hydraulic cylinder 9 is fixed in the groove by the top pressure plate and bolts, which can not only ensure the stability of the installation, but also reduce the vibration transmission of the hydraulic cylinder 9 during operation.

[0035] The extension end of the hydraulic cylinder 9 is equipped with a push frame 10, and the push frame 10 is slidably connected to the inside of the screen frame 8. A baffle 11 is fixed on one side of the push frame 10, and a collection frame 12 is slidably installed on the side of the machine body 1 near the screen frame 8.

[0036] The starting motor 5 drives the slag discharge screw 6 to rotate. The chips are washed into the waste trough 3 by the flushing mechanism 13. The rotating slag discharge screw 6 pushes the chips into the push frame 10 inside the screen frame 8. The flushing liquid flows back from the screen frame 8 mesh to the return trough 2. When the chips accumulate to a certain extent inside the push frame 10, the hydraulic cylinder 9 is activated. The extension end of the hydraulic cylinder 9 extends and pushes the push frame 10 to move outward from the screen frame 8. At the same time, the push frame 10 drives the baffle 11 to move and block the discharge end of the waste trough 3 to prevent chips from falling into the gap between the push frame 10 and the screen frame 8. During the movement of the push frame 10, the chips are pushed above the collection frame 12 and fall into the collection frame 12. Then, the extension end of the hydraulic cylinder 9 is activated to retract, driving the push frame 10 back into the screen frame 8. The chips that fall on the top of the baffle 11 are passively pushed down into the push frame 10 by the adhesion of the bottom of the waste trough 3.

[0037] Example 2

[0038] The following section provides a further description of the scheme in Example 1, focusing on its specific working method. See the description below for details:

[0039] like Figure 1 and Figure 4As shown, in a preferred embodiment, based on the above method, the cleaning mechanism 7 further includes a gear 701 and a reciprocating screw 702. The gear 701 is sleeved on the outer side of one end of the slag discharge screw 6. The reciprocating screw 702 is symmetrically rotated and installed inside the machine body 1, and the end of the reciprocating screw 702 passes through and extends to the outer side of the machine body 1. A gear 703 that meshes with the gear 701 is fixed to the end of the reciprocating screw 702. A slider 704 is threaded on the outer side of the reciprocating screw 702. A slide rod 705 is fixed to the bottom of the slider 704. An L-shaped rod 706 is fixed to one side of the slide rod 705. A push block 707 is fixed to the bottom end of both the L-shaped rod 706 and the bottom end of the slide rod 705, and the push block 707 is slidably connected to the top of the guide plate 4.

[0040] While the motor 5 drives the slag discharge screw 6 to rotate, it also drives the gear 1 701 to rotate. Then, the gear 1 701 drives the gear 2 703 and the reciprocating screw 702 to rotate. The push block 707 is slidably connected to the inclined guide plate 4, so that the reciprocating screw 702 drives the slider 704 and the push block 707 to move horizontally back and forth along the surface of the guide plate 4. The push block 707 performs secondary pushing and cleaning of the chips that are not washed away in time on the surface of the guide plate 4, pushing the chips into the waste trough 3, and then pushing and collecting them through the slag discharge screw 6.

[0041] like Figure 1 As shown, in a preferred embodiment, based on the above method, a protective cover 14 is further fixed inside the machine body 1, and the protective cover 14 is sleeved on the outside of the reciprocating lead screw 702. The bottom of the protective cover 14 is provided with a through-hole 15, and the inside of the through-hole 15 is slidably connected to the outside of the slide rod 705.

[0042] The protective cover 14 protects the outside of the reciprocating lead screw 702 to prevent chips from falling onto the reciprocating lead screw 702 during processing or rinsing, which could cause the grooves on the reciprocating lead screw 702 to become clogged, resulting in problems such as the slider 704 getting stuck and unable to move.

[0043] like Figure 1 As shown, in a preferred embodiment, based on the above method, the rinsing mechanism 13 further includes a rinsing pipe 1301 and a pump body 1302. The rinsing pipes 1301 are symmetrically installed on the inner side wall of the machine body 1. Spray nozzles 1305 are evenly installed on each rinsing pipe 1301. The pump body 1302 is installed inside the return tank 2. A diversion pipe 1303 is fixed to the output end of the pump body 1302. Fixed pipes 1304 are fixed to the branch ends of the diversion pipes 1303 respectively, and the top ends of the fixed pipes 1304 are respectively connected to the rinsing pipes 1301.

[0044] When the pump body 1302 is turned on, the flushing liquid inside the return tank 2 is delivered to the fixed pipe 1304 through the diversion pipe 1303. The flushing liquid enters the flushing pipe 1301 and is sprayed out from the nozzle 1305 to flush the inside of the machine body 1. The push block 707 cleans the chips into the waste tank 3.

[0045] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, all push blocks 707 are further configured as triangular blocks, and rubber pads are provided on the outer side of push blocks 707.

[0046] When the triangular pusher 707 moves along the guide plate 4, it can push the chips into the waste trough 3 below through the inclined surfaces on both sides, improving cleaning efficiency. The rubber pad increases the friction between the pusher 707 and the chips and the guide plate 4, preventing slippage and avoiding direct scraping of the surface of the guide plate 4, thus extending the service life of the guide plate 4. In addition, the rubber material has a certain elasticity, which can adapt to the slight undulations on the surface of the guide plate 4, ensuring that there are no dead corners in chip cleaning.

[0047] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, further, guide blocks are evenly arranged inside the lower part of the push frame 10, and brush bristles are provided at the bottom of the push frame 10, and an movable opening matching the push frame 10 is provided on one side of the screen frame 8.

[0048] The guide block inside the push frame 10 can guide the rinsing liquid to be discharged quickly, avoiding the accumulation of liquid residue and the generation of impurities. At the same time, it can organize the chips, making the chips concentrated in the middle of the push frame 10, which is convenient for subsequent cleaning.

[0049] The bottom bristles can adhere closely to the bottom surface of the screen frame 8, effectively cleaning residual chips during the movement of the push frame 10, preventing chips from getting stuck in the mesh of the screen frame 8, improving the thoroughness of chip cleaning, and ensuring the cleanliness of the inside of the device.

[0050] The movable opening on one side of the screen frame 8 facilitates the extension of the push frame 10 to the outside of the screen frame 8.

[0051] like Figure 1 As shown, in a preferred embodiment, based on the above method, the fixing pipe 1304 is a flexible hose, and the flushing pipe 1301 is installed inside the machine body 1 through a sleeve and a bracket. Bolts are uniformly arranged in a ring on the sleeve, and a limit block is provided at the end of the bolt.

[0052] The flexible hose 1303 can be flexibly adjusted according to the internal layout of the device, making it easy to install and maintain. The flushing pipe 1301 is installed by combining sleeves, brackets and bolts, which is easy to disassemble and fine-tune the angle. The rotation angle of the flushing pipe 1301 can be adjusted by adjusting the tightness of the bolts and the limit block at the end and the outside of the flushing pipe 1301 to meet the flushing needs in different processing scenarios. The limit block can prevent the flushing pipe 1301 from loosening, ensuring that the flushing pipe 1301 is installed firmly and avoiding displacement or falling off due to vibration, thus ensuring the continuous and stable operation of the flushing operation.

[0053] Example 3

[0054] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0055] First, start the pump body 1302 so that the flushing liquid in the return tank 2 flows into the flushing pipe 1301 through the diversion pipe 1303 and the fixed pipe 1304, and is sprayed out of the flushing machine body 1 from the nozzle 1305. At the same time, start the motor 5 to drive the slag discharge screw 6 to rotate, which drives the gear one 701 to rotate, and then causes the gear two 703 and the reciprocating screw 702 to operate.

[0056] The pusher block 707 slides in conjunction with the inclined guide plate 4. As the reciprocating screw 702 drives the slider 704 to move horizontally back and forth along the guide plate 4, it pushes the chips that are not flushed away in time to the waste trough 3, and then sends them into the pusher frame 10 inside the screen frame 8 by the slag discharge screw 6. The rinsing liquid flows back to the return tank 2 through the mesh of the screen frame 8 for recycling.

[0057] When the chips accumulate to a certain amount in the pusher frame 10, the hydraulic cylinder 9 is activated, and its telescopic end pushes the pusher frame 10 to move outward towards the screen frame 8. At the same time, the baffle 11 blocks the discharge end of the waste trough 3 to prevent chips from falling into the interlayer. When the pusher frame 10 moves, it pushes the chips to the collection frame 12. Then, the hydraulic cylinder 9 retracts, causing the pusher frame 10 to reset. Since the bottom of the waste trough 3 is attached to the baffle 11, when the baffle 11 moves, the chips on top of the baffle 11 are passively pushed into the pusher frame 10. When the turbidity of the flushing fluid exceeds 50 NTU, it needs to be replaced. The flushing fluid should be tested regularly, and the replacement should be determined based on the test results. At the same time, impurities in the return tank 2 should be cleaned regularly to keep the flushing fluid clean.

[0058] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
