[0003] The Chinese patent with announcement number CN110653659B discloses that the coolant drives the left spray ring to rotate through the impeller, and the coolant rushes downward obliquely through each left spray hole. On the other hand, the recovered coolant containing tiny metal particles enters the second liquid ring through the high-pressure metal pipe, and the coolant drives the right spray ring to rotate and rushes upward obliquely through each right spray hole. However, in this prior art, since the drilling end is in the process of continuous movement, when the drilling end part enters the workpiece to be opened, due to the blocking effect of the workpiece, most of the liquid sprayed from the right spray hole will directly act on the workpiece, which will cause the right spray hole to be unable to collide with the left spray hole to break the metal chips.

[0030] Embodiment 1

[0031] The flexible processing device for three holes of an axle comprises: a U-shaped frame 1; an adjusting plate 3, which is slidably arranged in the U-shaped frame 1 and is provided with two groups; a clamp 4, which is arranged in the U-shaped frame 1 and is located between the adjusting plates 3; a drilling mechanism 5, which is arranged on the adjusting plate 3 and close to one side of the clamp 4, and the drilling mechanism 5 comprises a mounting plate 51 arranged on the adjusting plate 3 and a cylinder 3 52 arranged at the center position of the mounting plate 51, a moving plate 53 is arranged at the telescopic end of the cylinder 3 52, and three motors 57 arranged in an annular arrangement are arranged on the moving plate 53, and a tap is fixedly connected to the end of the output shaft of the motor 57 56, the surface of the output shaft of the motor 57 is rotatably sleeved with a liquid outlet component 54, and the liquid outlet component 54 is close to the side surface of the tap 56 and is sequentially provided with a plurality of groups of annularly distributed inclined holes 545 and a plurality of annularly distributed inclined holes 546 in a direction approaching the tap 56, and an adjusting component 55 is provided between the liquid outlet component 54 and the mounting plate 51 to drive the cylinder three 52, and the cylinder three 52 pushes the moving plate 53 and the adjusting component 55 to move relative to each other, so as to control the inclined hole one 545 to open and the inclined hole two 546 to close, or the inclined hole one 545 to close and the inclined hole two 546 to open.

[0032] The axle is fixed by the clamp 4, and the adjustment plate 3 is moved so that the two groups of adjustment plates 3 are respectively located at the two ends of the axle. The two ends of the axle are processed simultaneously by the adjustment plate 3. The adjustment plate 3 drives the tap 56 to contact the end of the axle. When it is necessary to open a threaded hole, the motor 57 is started so that the motor 57 drives the tap 56 to rotate. In the initial state, the inclined hole 1 545 is in an open state, and the coolant inside the liquid outlet assembly is sprayed out from the inclined hole 1 545 along the inclined direction, while the inclined hole 2 546 is in a closed state, so that the liquid collection The coolant is sprayed out from the inclined hole 1 545, increasing the pressure of the coolant, making it easier to clean or break the waste chips. Since the distance between the inclined hole 1 545 and the tap 56 is large, the inclined hole 1 545 can spray the coolant to the end of the tap 56 away from the end of the liquid outlet assembly 54, so that the coolant can reach the connection between the axle and the tap 56 during the initial processing. At this time, the landing point of the coolant is far away, and the waste chips at the processing position can be broken or cleaned in time. Then the cylinder 3 52 is started, and the cylinder 3 52 drives the moving plate 53 The tap 56 moves to facilitate the continuous movement of the tap 56 into the end of the axle to process the threaded hole at the end of the axle. As the tap 56 continues to penetrate into the end of the axle, since the trajectory of the liquid sprayed from the inclined hole 545 does not change, most of the coolant directly acts on the end of the axle, and cannot directly act on the connection between the tap 56 and the axle, but indirectly acts on the connection between the tap 56 and the axle. The coolant pressure will be relatively small, and the waste chips cannot be broken in time. Therefore, as the moving plate 53 moves toward the direction close to the axle, the moving plate 53 During the movement, it will move relative to the adjustment component 55, so that the inclined hole 2 546 is opened, so that the coolant inside the liquid outlet component is sprayed out from the inclined hole 2 546, and the inclined hole 1 545 is closed, so that the liquid sprayed from the inclined hole 2 546 directly acts on the connection between the tap 56 and the axle. At this time, the coolant landing point is closer, and can directly act on the chip strips generated at the connection between the tap 56 and the axle during the processing process, and can break or clean the chip strips to avoid excessive accumulation of chip strips and reduce the accuracy of threaded hole processing. Among them, the angle between the inclined hole 1 545 and the inclined hole 2 546 and the horizontal plane is 15-30°, so that the liquid sprayed from the inclined hole 1 545 and the inclined hole 2 546 is sprayed in an inclined direction, so that the final landing point of the coolant can be on the tap 56.

[0033] In one embodiment, the liquid outlet assembly 54 includes a liquid storage cylinder 541 rotatably sleeved on the output shaft of the motor 57 and an annular partition 542 arranged in the liquid storage cylinder 541 along the radial direction, the annular partition 542 divides the liquid storage cylinder 541 into a liquid storage chamber and a liquid outlet chamber, a partition ring is arranged in the liquid outlet chamber along the axial direction of the liquid storage cylinder 541, and the partition ring divides the liquid outlet chamber into a second liquid outlet channel 544 and a first liquid outlet channel 543 from the inside to the outside along the radial direction, and the annular partition 542 is provided with a plurality of groups of through holes 5422 and through holes 542 in sequence from the inside to the outside along the radial direction. 1. The side wall of the liquid storage cylinder 541 is fixedly connected with a liquid inlet pipe located at the liquid storage cavity. The inclined hole 1 545 is connected with the liquid outlet channel 1 543, and the inclined hole 2 546 is connected with the liquid outlet channel 2 544. Specifically, the liquid inlet pipe inputs the coolant into the liquid storage cavity. After the coolant enters the liquid storage cavity, there are two different ejection channels. One channel is that the liquid in the liquid storage cavity can enter the liquid outlet channel 1 543 through the through hole 1 5421 and finally eject from the inclined hole 1 545. The other channel is that the liquid in the liquid storage cavity can enter the liquid outlet channel 2 544 through the through hole 2 5422 and finally eject from the inclined hole 2 546. Among them, the side wall of the liquid storage cylinder 541 is fixedly connected to the movable disk 53 through a bracket, and a avoidance hole adapted to the output shaft of the motor 57 is provided in the liquid storage cylinder.

[0034] In one embodiment, the adjustment assembly 55 includes a fixed plate 551 disposed on the mounting plate 51, and the fixed plate 551 is respectively provided with a plurality of groups of annularly distributed fixed rods 1 552 and a plurality of annularly distributed fixed rods 2 553, the diameter of the circular area surrounded by the plurality of groups of the fixed rods 2 553 is larger than the circular area surrounded by the plurality of groups of the fixed rods 1 552, and one end of the fixed rods 2 553 passes through the through holes on the movable plate 53, the liquid storage cylinder 541 and the annular partition 542 in sequence. The first through hole 5421 extends to the first liquid outlet channel 543, one end of the fixed rod 1 552 sequentially penetrates the movable plate 53, the liquid storage cylinder 541 and the second through hole 5422 on the annular partition 542 and extends to the second liquid outlet channel 544, the surface of the fixed rod 1 552 is located in the first liquid outlet channel 543 and the surface of the fixed rod 2 553 is located in the liquid storage cavity. A sealing component is provided. Specifically, in the initial state, there is no sealing component intercepting the through hole 1 5421, and the liquid in the liquid storage cavity can The liquid enters the liquid outlet channel 1 543 through the through hole 1 5421 and is finally ejected from the inclined hole 1 545. The sealing component on the fixed rod 1 552 covers and intercepts the through hole 2 5422. Therefore, the coolant in the liquid storage chamber cannot enter the liquid outlet channel 2 544. When the movable plate 53 drives the liquid storage cylinder 541 to move away from the mounting plate 51, the liquid storage cylinder 541 and the sealing component will move relative to each other. Since the sealing component on the fixed rod 2 553 is located in the liquid outlet channel 1 543, During the movement of the liquid storage cylinder 541, the sealing component on the second fixing rod 553 will cover the first through hole 5421. At this time, since the sealing component on the first fixing rod 552 is arranged in the liquid storage cavity, during the movement of the liquid storage cylinder 541, the sealing component on the first fixing rod 552 will be farther and farther away from the second through hole 5422 until the sealing component is separated from the second through hole 5422. The coolant in the liquid storage cavity enters the second liquid outlet channel 544 from the second through hole 5422 and is then sprayed out from the second inclined hole 546.

[0035] In order to make the inclined hole 1 545 and the inclined hole 2 546 each have a time period for spraying, the sealing assembly includes a fixed rod 2 553 end and a fixed ring 554 arranged on the surface of the fixed rod 1 552, and the surfaces of the fixed rod 1 552 and the fixed rod 2 553 are both provided with springs 555. The surfaces of the fixed rod 1 552 and the fixed rod 2 553 are movably sleeved with a sealing ring 556 adapted to the through hole 1 5421 and the through hole 2 5422 at one end of the spring 555. The sealing ring 556 is located at one end close to the annular partition 542. Specifically, in the initial state, refer to Figure 3, the sealing ring 556 on the fixing rod 1 552 covers the through hole 2 5422 on the annular partition 542, and the spring 555 on the fixing rod 1 552 is in a compressed state. When the liquid storage cylinder 541 moves, the spring 555 on the fixing rod 1 552 pushes the sealing ring 556 to move under the action of the restoring elastic force, so that the sealing ring 556 covers the through hole 2 5422 until the spring 555 on the fixing rod 1 552 is in a free length state. The spring 555 on the fixing rod 1 552 cannot be extended, so the sealing ring 556 on the fixing rod 1 552 is separated from the through hole 2 5422. At this time, the through hole 2 5422 is in an open state. Figure 4 At the same time, the sealing ring 556 on the second fixing rod 553 can cover the through hole 1 5421, and as the liquid storage cylinder 541 moves, the annular partition 542 can squeeze the sealing ring 556 on the second fixing rod 553, thereby squeezing the spring 555 on the second fixing rod 553, so that the liquid storage cylinder 541 continues to move a distance away from the mounting plate 51.

[0036] In one embodiment, a cylinder 2 is provided between the U-shaped frame 1 and the adjusting plate 3. The adjusting plate 3 is pushed by the cylinder 2 so that the drilling mechanism 5 on the adjusting plate 3 can contact the end of the axle.

[0037] Since the trajectory of the coolant sprayed out of the inclined hole 545 is relatively long, in order to ensure the effect of breaking or cleaning the waste chips, the diameter of the inclined hole 1 545 is smaller than the diameter of the inclined hole 2 546, which can increase the pressure of the coolant sprayed out and facilitate the breaking or cleaning of the waste chips.

[0038] In one embodiment, the clamp 4 includes a mounting frame 41 arranged on the U-shaped frame 1, a limiting member 44 is arranged on the top of the mounting frame 41, a mounting block 45 is arranged on the mounting frame 41 and below the limiting member 44, limiting members 46 are detachably arranged on both sides of the mounting block 45, a cylinder 42 is arranged on the mounting frame 41 and on one side of the mounting block 45, a support block 43 is arranged at the telescopic end of the cylinder 42, a V-shaped groove is opened on the support block 43, the axle is placed on the support block 43, and the positions of the limiting members 46 on both sides of the mounting block 45 are adjusted so that the two sets of limiting members 46 can limit and fix the axle under the cooperation of the limiting member 44.

[0039] Embodiment 2

[0040] In order to cooperate with the technical solution recorded in the first embodiment, a processing method of a flexible processing device for three axle holes is provided, using any flexible processing device for three axle holes as recorded in the first embodiment, comprising the following steps:

[0041] S1: Fix the axle by the clamp 4, and move the adjustment plate 3 so that two sets of adjustment plates 3 are respectively located at two ends of the axle;

[0042] S2: In the initial state, the inclined hole 1 545 is in an open state, and the coolant in the liquid outlet assembly 54 is sprayed out from the inclined hole 1 545 in an inclined direction, and the coolant falls far away, while the inclined hole 2 546 is in a closed state, and the motor 57 and the cylinder 3 52 are started, so that the motor 57 drives the tap 56 to rotate, and the threaded hole of the axle is processed;

[0043] S3: The cylinder three 52 drives the movable plate 53 to move toward the direction close to the axle, pushing the tap 56 into the axle to process the threaded hole. At the same time, the movable plate 53 will move relative to the adjustment component 55 during the movement, so that the inclined hole two 546 is opened, and the coolant inside the liquid outlet component is sprayed out from the inclined hole two 546. The coolant falls close to the point where it lands, and the inclined hole one 545 is closed.

[0044] As the depth of the tap 56 entering the axle changes, the opening or closing of the inclined hole 1 545 and the inclined hole 2 546 can be adjusted. By changing the landing point of the coolant spray, the chip strips can be quickly cut or cleaned with the maximum pressure, avoiding the situation where the force is unloaded due to indirect action, and effectively avoiding the problem of low processing accuracy caused by the failure to quickly cut or clean the chip strips in time.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
