[0031] The present invention provides a honing rod with multi-axis linkage as Figures 1 to 6 shown, which includes a main rod 1, a connecting rod 2 and a honing head 3. The connecting rod 2 is arranged between the main rod 1 and the honing head 3. The connecting rod 2 and the honing head 3 adopt an integral molding process. And diamond honing strips 4 are installed on the outer part of the honing head 3. There are multiple diamond honing strips 4, and the multiple diamond honing strips 4 are evenly distributed around the honing head 3. By using the cooperation of the main rod 1, the connecting rod 2, the honing head 3 and the diamond honing strips 4, honing processing is carried out on the workpiece hole.

[0032] Referring to Figure 1 、 Figure 2 as shown in, a fixing ring 5 is fixedly connected to the connecting rod 2, and a positioning sleeve 8 is fixedly connected to the main rod 1. A positioning component is used to connect between the fixing ring 5 and the positioning sleeve 8, so that the main rod 1 and the connecting rod 2 are connected into a whole.

[0033] Referring to Figure 2 as shown in, considering that in the prior art, when the honing rod is processed and used, there will be a lot of dust debris at the hole. If it is not cleaned in time, it will affect the honing efficiency. To realize the cleaning of the dust debris, a wind force component is arranged between the main rod 1, the connecting rod 2 and the honing head 3. The wind force component includes a gas channel 21, air holes 22 and side holes 23. The gas channel 21 is opened inside the main rod 1, and the gas channel 21 extends to the inside of the connecting rod 2. The side holes 23 are opened on the side wall of the main rod 1, and the side holes 23 are communicated with the gas channel 21. The air holes 22 are opened on the outer wall of the honing head 3, and the air holes 22 are communicated with the gas channel 21. And air holes 22 are arranged at the positions between adjacent two diamond honing strips 4. The air outlet end of the air hole 22 is located between the two diamond honing strips 4. When the honing head 3 is inside the hole, there will be a certain gap between the air outlet end of the air hole 22 and the inner wall of the hole, which is convenient for air flow to enter the hole.

[0034] Gas is conveyed into the gas channel 21 from the side holes 23, and the gas is ejected from the air holes 22 to blow off the dust debris adhering to the inner wall of the hole. At the same time, the residual dust debris on the diamond honing strips 4 can also be blown off, realizing the effect of cleaning the dust debris and improving the use efficiency of the honing rod.

[0035] And the blown-off dust debris falls out from the bottom end of the hole.

[0036] Referring to Figure 1 、 Figure 2As shown in the figure, a flow guide plate 24 is fixedly connected to the outer wall of the main rod 1. The flow guide plate 24 is correspondingly distributed with the side holes 23. The flow guide plate 24 is arc-shaped and is inclined, inclined towards the concave side. When the main rod 1 is driven by a driving device (such as a motor) to rotate at a high speed, the main rod 1 and the flow guide plate 24 rotate synchronously, and the concave side of the flow guide plate 24 is in the oncoming wind direction. The received gas enters the side holes 23, then enters the inside of the gas passage 21, and is ejected from the air holes 22 to blow off the dust debris adhering to the inner wall of the hole.

[0037] By setting structures such as the flow guide plate 24 and the wind power assembly, the present invention utilizes the high-speed rotation of the main rod 1 to receive gas. The gas is ejected from the air holes 22 to blow off the dust debris adhering to the inner wall of the hole, and at the same time, it can also blow off the residual dust debris on the diamond honing strip 4, achieving the effect of cleaning the dust debris and improving the use efficiency of the honing rod.

[0038] The inner diameter of the air hole 22 gradually becomes smaller in the direction away from the gas passage 21. When the gas passes through the air hole 22, due to the inner diameter of the air hole 22 gradually becoming smaller in the direction away from the gas passage 21, the gas is accelerated, improving the blowing effect.

[0039] Considering that when the honing rod processes holes with different depths, it is necessary to replace the honing heads 3 with different lengths. The existing honing heads 3 are not simple and convenient to replace, and the operation is relatively complex. To improve the replacement efficiency, the positioning assembly includes a fixed block 6, a positioning shaft 7, and a jack 9. The fixed block 6 is fixedly connected to the outer wall of the fixed ring 5. The positioning shaft 7 is fixedly connected to the surface of the fixed block 6 facing the positioning sleeve 8. The jack 9 is opened on the positioning sleeve 8, and the positioning shaft 7 extends into the inside of the jack 9.

[0040] The positioning assembly further includes a first circular groove 10, a second circular groove 11, a limiting post 12, and a limiting hole 15. The limiting hole 15 is opened on the positioning shaft 7. The first circular groove 10 is opened on the outer wall of the positioning sleeve 8. The second circular groove 11 is opened on the inner wall of the first circular groove 10. The second circular groove 11 communicates with the jack 9. The limiting post 12 is slidably arranged inside the second circular groove 11, and the limiting post 12 is inserted into the inside of the limiting hole 15.

[0041] One end of the limiting post 12 away from the positioning shaft 7 is fixedly connected with a round block 13. A spring 14 is sleeved outside the limiting post 12. One end of the spring 14 is fixedly connected to the round block 13, and the other end of the spring 14 is fixedly connected to the inner wall of the first circular groove 10. The end of the limiting post 12 that cooperates with the limiting hole 15 is provided with a first inclined cut 16, and the end of the positioning shaft 7 located inside the jack 9 is provided with a second inclined cut 17. The first inclined cut 16 cooperates with the second inclined cut 17.

[0042] During actual use, the operator docks the main rod 1 with the connecting rod 2, and the positioning shaft 7 is inserted into the corresponding jack 9. Refer to Figure 3When the second bevel cut 17 contacts the first bevel cut 16, the limit column 12 will move upward. When the limit hole 15 corresponds to the position of the limit column 12, the reset force of the spring 14 resets the limit column 12 and inserts it into the limit hole 15, thereby realizing the rapid replacement of the honing head 3.

[0043] If the main rod 1 and the connecting rod 2 need to be separated, the operator pulls the round block 13 in a direction away from the positioning shaft 7 so that the limiting column 12 is drawn out from the inside of the limiting hole 15 , thereby releasing the restriction on the positioning shaft 7 .

[0044] By providing structures such as a positioning assembly, the honing head 3 can be quickly replaced, further improving the use efficiency of the honing rod.

[0045] Furthermore, multiple groups of positioning components are provided, and the multiple groups of positioning components are evenly distributed around the main rod 1 , and multiple positioning shafts 7 cooperate and work together to improve the stability of the connection between the main rod 1 and the connecting rod 2 .

[0046] Reference Figure 1 , Figure 3 , Figure 5 As shown in the figure, a circular sleeve 18 is slidably provided on the main rod 1, and an arc plate 19 is fixedly connected to the inner wall of the circular sleeve 18. There are multiple arc plates 19, and the multiple arc plates 19 are evenly distributed around the axis of the circular sleeve 18. A limiting channel 20 that cooperates with the corresponding round block 13 is formed between two adjacent arc plates 19.

[0047] When the main rod 1 is docked with the connecting rod 2, the circular sleeve 18 is staggered with the positioning sleeve 8, which does not affect the sliding of the round block 13 in the direction away from the positioning axis 7. After the main rod 1 is docked with the connecting rod 2, the circular sleeve 18 is controlled to reset, the circular sleeve 18 surrounds the outside of the positioning sleeve 8, and the round block 13 extends into the corresponding limiting channel 20, so that the circular sleeve 18 will not rotate at will. At the same time, the circular block 13 is limited, so that during the use of the honing rod, the limit column 12 and other structures will not slide at will.

[0048] Reference Figure 2 As shown in the figure, a square groove 30 is provided at one end of the main rod 1 close to the connecting rod 2, and a block 31 is inserted into the inside of the square groove 30. The block 31 is fixedly connected to the connecting rod 2. The square groove 30 and the block 31 are provided to improve the stability of the synchronous rotation of the main rod 1 and the connecting rod 2.

[0049] The present invention also discloses an intelligent adaptive control system for a multi-axis linkage honing rod, which is applied to the above-mentioned multi-axis linkage honing rod, and also includes a vacuum tank 27 and a pump body 29. The vacuum tank 27 is connected with an air pipe 25. An air sleeve 32 is rotatably arranged on the main rod 1. The air sleeve 32 is connected with the side hole 23. One end of the air pipe 25 away from the vacuum tank 27 is connected with the air sleeve 32. An electromagnetic valve 26 is fixedly installed on the air pipe 25. A pressure sensor 28 is fixedly installed inside the vacuum tank 27. The pump body 29 is connected with the vacuum tank 27.

[0050] For the holes with no opening at the bottom, when using the cooperation of the main rod 1, the connecting rod 2, the honing head 3 and the diamond honing strip 4 to hone the workpiece holes, start the pump body 29 and use the wind power assembly to suck and process the dust debris.

[0051] When the main rod 1 is in a rotating state, the air sleeve 32 is always connected to the side hole 23. In actual use, a bracket can be set to fix the position of the air sleeve 32.

[0052] And a filtering device (not shown in the figure) is provided at the air pipe 25. The filtering device includes structures such as a filter screen to filter and process the dust debris.

[0053] In actual use, the solenoid valve 26 can be closed, and the pump body 29 sucks the vacuum tank 27 to make the inside of the vacuum tank 27 in a vacuum state. Then open the solenoid valve 26. At this time, there is a large pressure difference between the vacuum tank 27 and the port position of the air hole 22. And with the suction cooperation of the pump body 29, a large suction force will be generated to prevent structures such as the gas passage 21, the air hole 22 and the side hole 23 from being blocked by debris.

[0054] And the pressure sensor 28 monitors the pressure inside the vacuum tank 27, and a controller is arranged between the pressure sensor 28 and the pump body 29 to monitor the pressure inside the vacuum tank 27, so as to control the state of the pump body 29 to achieve the effect of intelligent adaptive regulation. The controller and its working principle are both common existing technologies and will not be elaborated here.
