Description

Technical Field

[0001] This utility model relates to the technical field of milling, and more specifically, to a milling fixture with a coolant guide groove. Background Technology

[0002] In the field of machining, milling, as a common metal cutting method, is widely used for machining various parts with flat surfaces, grooves, curved surfaces, and other structures. The cutting chips mix with the coolant and easily accumulate on the clamping surfaces, locating grooves, and bases of the fixture, forming a mixture of "coolant + chips." If this mixture is not drained in time, the coolant cannot be recycled, and the risk of chips re-adhering to the workpiece or cutting tool increases.

[0003] After the coolant is sprayed from the nozzle, some of it will directly act on the cutting area, but a large amount of coolant will flow randomly and may spread disorderly along the surface of the fixture, failing to concentrate on the critical parts that need cooling (such as the contact point between the tool edge and the workpiece).

[0004] Therefore, a milling fixture with a coolant guide groove is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a milling fixture with a coolant guide groove to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a milling fixture with a coolant guide channel, comprising a worktable, a guide channel provided on one side of the upper part of the worktable, multiple sliding grooves provided on the side of the upper part of the worktable away from the guide channel, two oppositely arranged fixture mechanisms mounted on the upper part of the worktable, a support plate on one side of the worktable, a circulation mechanism mounted on the side of the support plate away from the worktable, a milling machine mounted on the upper part of the support plate, circulation boxes mounted on both sides of the worktable along the flow direction of the guide channel, one side of each circulation box communicating with the guide channel, and an inlet pipe mounted on the side of each circulation box away from the guide channel, a movable plate mounted on the side of the worktable away from the support plate, a hinge mounted on one side of the movable plate, and the movable plate rotatably connected to the worktable via the hinge.

The push rod is connected to the clamping block through a bearing inside the baffle. A fixed plate is installed below the push rod and fixed to the side of the baffle. Multiple sliders are installed below the fixed plate, and multiple nuts are installed above the fixed plate. The sliders are all connected to the nuts through bolts passing through the fixed plate. The sliders slide inside the groove.

[0008] Preferably, the circulation mechanism includes a water pump, an outlet pipe, a first conduit, a connecting pipe, a second conduit, and a first nozzle. The outlet pipe is installed above the water pump, and the first conduit is installed at the end of the outlet pipe away from the water pump. The connecting pipe is installed above the first conduit, and the second conduit is installed above the connecting pipe. Multiple first nozzles are installed on one side of the second conduit. The input ends on both sides of the water pump are connected to the circulation tank through inlet pipes.

[0009] Preferably, an interface is installed on the upper part of one side of the baffle, a third conduit is installed inside the interface, and both ends of the first conduit are connected to the third conduit through the interface.

[0012] Preferably, an input port is installed on the top of the circulation box, and an output port is installed on the side of the circulation box away from the workbench.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] Compared with existing technologies, this milling fixture with coolant guide channels sprays coolant in multiple directions during milling through nozzles installed above the baffle and on the side of the support plate, increasing the effective area of ​​the coolant and thus rapidly cooling the machine. It also washes away the milling debris generated during milling from the milling area, reducing the risk of debris adhering to the workpiece or tool.

[0015] Compared with existing technologies, this milling fixture with a coolant guide channel allows the mixture to flow to the bottom through the inclined channel.

[0022] Example

[0023] As attached Figures 1 to 4The milling fixture shown includes a worktable 1, a coolant guide channel 2 on one side of the upper part of the worktable 1, multiple sliding grooves 3 on the side of the upper part of the worktable 1 away from the guide channel 2, two oppositely arranged clamping mechanisms 4 mounted on the upper part of the worktable 1, a support plate 5 on one side of the worktable 1, a circulation mechanism 6 mounted on the side of the support plate 5 away from the worktable 1, a milling machine 7 mounted on the upper part of the support plate 5, and circulation boxes 8 mounted on both sides of the worktable 1 along the flow direction of the guide channel 2. One side of each circulation box 8 is connected to the guide channel 2, and an inlet pipe is installed on the side of each circulation box 8 away from the guide channel 2. 9. A movable plate 11 is installed on the side of the workbench 1 away from the support plate 5. A hinge 10 is installed on one side of the movable plate 11, and the movable plate 11 is rotatably connected to the workbench 1 through the hinge 10. The milling material is fixed by the clamping mechanism 4 for operation. Then, the circulation mechanism 6 pumps the coolant in the circulation tank 8 to the nozzles installed above the baffle 401 and on the side of the support plate 5 to spray onto the milling area for cooling. Then, the waste chips and coolant are transported to the bottom through the inclined groove 15. The coolant enters the interior of the guide groove 2 through the filter screen 16 and circulates back to the circulation tank 8 for circulation. The accumulated mixture is discharged through the movable plate 11.

[0024] The clamping mechanism 4 includes a baffle 401, a fixed plate 402, a slider 403, a bolt 404, a nut 405, a push rod 406, a bearing 407, and a clamping block 408. A push rod 406 is mounted on one side of the baffle 401, and a clamping block 408 is mounted on the side of the baffle 401 away from the push rod 406. The push rod 406 passes through the bearing 407 inside the baffle 401 and connects to the clamping block 408. A fixed plate 402, fixed to the side of the baffle 401, is mounted below the push rod 406. Multiple sliders 403 are mounted below the fixed plate 402, and a clamping block 408 is mounted above the fixed plate 402. Multiple nuts 405 and slider 403 are connected to nuts 405 by bolts 404 passing through fixed plate 402. Slider 403 slides inside slide groove 3. Slider 403 moves through slide groove 3 and fixed plate 402 by bolts 404 and nuts 405, thereby fixing the position of baffle 401. Rotate push rod 406 on one side of baffle 401. Push rod 406 rotates and moves, driving clamping block 408 to move. Multiple push rods 406 and clamping block 408 move, thereby fixing milling material. Baffle 401 stands on milling material to ensure that coolant does not splash out of the processing area.

[0025] The circulation mechanism 6 includes a water pump 601, an outlet pipe 602, a first conduit 603, a connecting pipe 604, a second conduit 605, and first nozzles 606. The outlet pipe 602 is installed above the water pump 601. The first conduit 603 is installed at the end of the outlet pipe 602 away from the water pump 601. The connecting pipe 604 is installed above the first conduit 603. The second conduit 605 is installed above the connecting pipe 604. Multiple first nozzles 606 are installed on one side of the second conduit 605. The input ends on both sides of 601 are connected to the circulation tank 8 through the inlet pipe 9. The coolant in the circulation tank 8 on both sides enters the water pump 601 through the inlet pipe 9, and is pressurized by the water pump 601 to enter the outlet pipe 602. The coolant enters the first conduit 603 through the outlet pipe 602, and then enters the second conduit 605 through the connecting pipe 604, and is sprayed out from the first nozzle 606. This ensures that the coolant flushes and cools the milling material while pushing the accumulated liquid and chips downward to prevent accumulation.

[0026] Each of the baffles 401 has an interface 12 installed on the upper side of each side. Each interface 12 has a third conduit 13 installed inside it. Both ends of the first conduit 603 are connected to the third conduit 13 through the interface 12. Each of the third conduits 13 has multiple second nozzles 14 installed on its upper side. After passing through the first conduit 603, the coolant enters the interior of the third conduit 13 through the interface 12 and is sprayed onto the side of the milling material through the multiple second nozzles 14 installed on its upper side, increasing the contact area between the coolant and the milling material, thereby ensuring the cooling effect.

[0027] A sloping groove 15 is provided between the two baffles 401, and a filter screen 16 is installed on the side of the sloping groove 15 near the movable plate 11. The side of the filter screen 16 away from the sloping groove 15 is connected to the guide groove 2. The mixture generated by milling material flows to the bottom through the sloping groove 15. The inclined sloping groove 15 ensures that it will not accumulate. After being filtered by the filter screen 16 at the bottom, the filtered coolant flows into the circulation tank 8 through the guide groove 2 on one side, ensuring that the coolant is recycled and saving costs.

[0028] The movable plate 11 rotates with the hinge 10 and is parallel to the bottom of the filter screen 16. The two sides of the movable plate 11 are tightly fitted with the baffle 401. After the milling operation is completed, the movable plate 11 is pushed to rotate around the hinge 10 until it is parallel to the bottom of the filter screen 16, so that the movable plate 11 is at the same elevation as the bottom of the inclined groove 15. This facilitates the quick cleaning of the mixture accumulated at the bottom and ensures smooth circulation of the coolant.

[0029] The circulation tank 8 has an inlet 17 installed on its upper part and an outlet 18 installed on the side of the circulation tank 8 away from the workbench 1. Coolant is injected through the inlet 17 on the upper part of the circulation tank 8 to ensure sufficient coolant and avoid excessive coolant loss due to cleaning the mixture, which would reduce the cooling effect due to insufficient coolant during operation. After the operation is completed, the coolant inside the circulation tank 8 is discharged through the outlet 18 to prevent the coolant from deteriorating and causing the conduit to become blocked.

[0030] The working process of this utility model is as follows: In use, firstly, the slider 403 moves through the slide groove 3 and fixes the fixing plate 402 with bolts 404 and nuts 405, thereby fixing the position of the baffle 401. The push rod 406 on one side of the baffle 401 is rotated and moves, driving the clamping block 408 to move. Multiple push rods 406 and clamping blocks 408 move, thereby fixing the milling material, and the baffle 401 stands on the milling material to ensure that the coolant will not splash out of the processing area.

[0031] Then, coolant is injected through the upper inlet 17 of the circulation tank 8 to ensure sufficient coolant. The coolant in the circulation tanks on both sides enters the water pump 601 through the inlet pipe 9, and is pressurized by the water pump 601 to enter the outlet pipe 602. The coolant enters the first conduit 603 through the outlet pipe 602, and then enters the second conduit 605 through the connecting pipe 604, and is sprayed out from the first nozzle 606. This ensures that the coolant flushes and cools the milling material while pushing the accumulated liquid and chips downward to prevent accumulation. At the same time, the coolant enters the third conduit 13 through the interface 12 after passing through the first conduit 603, and is sprayed out to the side of the milling material through multiple second nozzles 14 installed above the third conduit 13, increasing the contact area between the coolant and the milling material, thereby ensuring the cooling effect.

[0032] Then, the mixture generated from milling the material flows to the bottom through the inclined chute 15. The inclined chute 15 ensures that no accumulation occurs. After being filtered by the filter screen 16 at the bottom, the filtered coolant flows into the circulation tank 8 through the guide channel 2 on one side, ensuring the coolant is recycled and saving costs. After the milling operation is completed, the movable plate 11 is pushed to rotate around the hinge 10 until it is parallel to the bottom of the filter screen 16, so that the movable plate 11 is at the same elevation as the bottom of the inclined chute 15. This facilitates quick and easy cleaning of the mixture accumulated at the bottom, ensuring smooth coolant circulation. Finally, after the work is completed, the coolant inside the circulation tank 8 is discharged through the outlet 18 to prevent the coolant from deteriorating and causing blockage of the conduits.
