During the movement of the pressure head in the first direction near the second end, the pressure head can press the fourth end of the connecting rod to rotate in a direction near the first shaft and cause the third end of the connecting rod to rotate away from the first shaft.

[0019] In some embodiments, a sleeve is provided at the first end of the first shaft, and the driver, the reducer and the sleeve are connected in sequence;

[0020] The pressure head includes a first pressure head, a first elastic element, and a second pressure head.

[0046] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] The following description, with reference to the accompanying drawings, describes an embodiment of the jack cylinder rust removal machine of the present invention. For example... Figures 1 to 6 As shown, the jack cylinder rust removal machine according to an embodiment of the present invention includes a rust removal head and a drive unit.

[0048] The rust removal head includes a first shaft 1, a drive unit, and a cleaning brush. The first shaft 1 extends in a first direction. The cleaning brush has a cleaning surface for cleaning and is connected to the first shaft 1 via the drive unit. The first shaft 1 can drive the cleaning brush to rotate, and the drive unit can move the cleaning brush relative to the first shaft 1 from a first cleaning position to a second cleaning position. In the first cleaning position, at least a portion of the cleaning surface of the cleaning brush faces away from the first shaft 1 in the first direction. In the second cleaning position, at least a portion of the cleaning surface of the cleaning brush faces away from the first shaft 1 radially. The drive unit is connected to the first shaft 1 and can drive the first shaft 1 to rotate. The drive unit can drive the cleaning brush to move between the first cleaning position and the second cleaning position via the drive unit.

[0049] According to an embodiment of the present invention, the drive unit of the jack cylinder rust removal machine can drive the first shaft 1 to rotate, thereby causing the first shaft 1 to drive the cleaning brush to rotate, so that the cleaning brush can clean the inner wall surface of the deep hole of the jack cylinder. The drive unit can also drive the cleaning brush to move between a first cleaning position and a second cleaning position via a transmission unit. Specifically, in the first cleaning position, the cleaning brush is located at the end of the first shaft 1, and the cleaning surface of the cleaning brush faces away from the first shaft 1 in a first direction. That is, in the first cleaning position, the cleaning surface of the cleaning brush is perpendicular to the first direction, thereby facilitating the rotation of the cleaning brush to clean the bottom surface, arc surface, and bottom inner hole inside the jack cylinder. In the second cleaning position, the cleaning brush is located on the side of the first shaft 1, and at least a portion of the cleaning surface of the cleaning brush faces away from the first shaft 1 in a radial direction, thereby allowing the rotation of the cleaning brush to clean the inner circumferential surface inside the jack cylinder. The cleaning brush moves relative to the first shaft 1 from the first cleaning position to the second cleaning position, thereby enabling the cleaning brush to have multiple cleaning modes for better cleaning of the inside of the jack cylinder.

[0050] Therefore, the jack cylinder rust removal machine according to the present invention has the advantage of facilitating the cleaning of the jack cylinder.

[0051] like Figures 1 to 4As shown, in some embodiments, there are multiple cleaning brushes. The drive unit can drive the multiple cleaning brushes to move between a first cleaning position and a second cleaning position via a transmission unit. The first cleaning position is located radially on the side of the first shaft 1 adjacent to the second cleaning position. Multiple cleaning brushes can improve cleaning efficiency. The first cleaning position is located inside the second cleaning position, and the orientation of the cleaning surface changes; that is, as the cleaning brush moves from the first cleaning position to the second cleaning position, the cleaning brush rotates away from the first shaft 1.

[0052] In a first cleaning position, at least a portion of the cleaning surface of each cleaning brush faces away from the first shaft 1 in a first direction. In a second cleaning position, a plurality of cleaning brushes are arranged around the first shaft 1, spaced apart in the circumferential direction, and at least a portion of the cleaning surface of each cleaning brush faces away from the first shaft 1 in the radial direction. The first direction can be a vertical direction; for example, if the first shaft 1 extends vertically, at least a portion of the cleaning surface of each cleaning brush faces downward in the first cleaning position. In the second cleaning position, a plurality of cleaning brushes are arranged around the first shaft 1, spaced apart in the circumferential direction, and at least a portion of the cleaning surface of each cleaning brush faces horizontally.

[0053] like Figure 1 and Figure 2 As shown, in some embodiments, in the first cleaning position, the thickness direction of each cleaning brush is a first direction, and multiple cleaning brushes are assembled to form a circular disc structure. This circular disc structure formed by multiple cleaning brushes in the first cleaning position facilitates cleaning of the bottom surface of the jack cylinder when the cleaning brushes rotate. For example, in the first cleaning position, the thickness direction of each cleaning brush is the vertical direction.

[0054] like Figure 3 and Figure 4 As shown, in the second cleaning position, the thickness direction of each cleaning brush is radial to the first axis 1. For example, in the second cleaning position, the thickness direction of each cleaning brush is horizontal.

[0055] like Figures 1 to 4 and Figure 6 As shown, in some embodiments, the transmission unit includes a pressure head, an intermediate sleeve 3, and multiple connecting rods 4.

[0056] The intermediate sleeve 3 is fixed on the first shaft 1, and the connecting rod 4 is hinged to the intermediate sleeve 3. Each cleaning brush is connected to the third end 41 of at least one connecting rod 4. The connecting rod 4 can drive the cleaning brush to move from the first cleaning position to the second cleaning position.

[0057] The drive unit includes a driver 5 and an ejection device. The driver 5 is connected to the first end 11 of the first shaft 1. The driver 5 can drive the first shaft 1 to rotate, which in turn drives the intermediate sleeve 3 and multiple connecting rods 4 to rotate, thereby driving the cleaning brush connected to the connecting rods 4 to rotate. Specifically, the first end 11 of the first shaft 1 is provided with a rotating sleeve 13, and the driver 5, the reducer 51, and the rotating sleeve 13 are connected in sequence. The reducer 51 can easily adjust the rotation speed of the first shaft 1. For example, the driver 5 is a motor, and the first end 11 of the first shaft 1 is its upper end. After the cleaning brush is in the second cleaning position, the cutter of the drive unit is fed axially so that the driver 5 can rotate the rotating sleeve 13. At this time, the movement trajectory of the wire brush is an arc surface. The reducer 51 can make the first shaft 1 reach two speeds: 50 r / min and 160 r / min.

[0058] The ejection device cooperates with the fourth end 42 of multiple connecting rods 4. The ejection device can drive the connecting rods 4 to rotate relative to the intermediate sleeve 3 so as to move multiple cleaning brushes from the first cleaning position to the second cleaning position.

[0059] Specifically, the ejection device includes a body 52 and a push tube 53. The body 52 (with an ejection driver inside) can drive the push tube 53 to move in a first direction. The push tube 53 is sleeved on the outer periphery of the first shaft 1. A pressure head is sleeved on the first shaft 1 and is slidably connected to the first shaft 1 (the pressure head can rotate relative to the first shaft 1). The pressure head is located on the side of the intermediate sleeve 3 facing away from the cleaning brush in the first direction. The push tube 53 can push the pressure head to move in the first direction near the second end 12. The pressure head cooperates with the fourth end 42 of a plurality of connecting rods 4. During the movement of the pressure head in the first direction near the second end 12, the pressure head can press the fourth end 42 of the connecting rods 4 to rotate in the direction near the first shaft 1, causing the third end 41 of the connecting rods 4 to rotate away from the first shaft 1. That is, during the process of the push tube 53 pushing the pressure head to move in the first direction near the second end 12, the pressure head can press the fourth end 42 of the connecting rods 4, and the fourth end 42 rotates relative to the pressure head in the direction near the first shaft 1, thereby driving the cleaning brush to move from the first cleaning position to the second cleaning position. For example, the body 52 can drive the push tube 53 to move downward, and the push tube 53 can push the pressure head to move downward. During the downward movement of the pressure head, the pressure head can press the fourth end 42 of the connecting rod 4 to rotate in a direction adjacent to the first shaft 1 and cause the third end 41 of the connecting rod 4 to rotate in a direction away from the first shaft 1.

[0060] like Figures 1 to 4 As shown, in some embodiments, the pressure head includes a first pressure head 61, a first elastic element 62, and a second pressure head 63.

[0061] The first pressure head 61 and the second pressure head 63 are both slidably sleeved on the first shaft 1 (the first pressure head 61 and the second pressure head 63 can rotate relative to the first shaft 1). The first pressure head 61 can abut against the rotating sleeve 13 in the first direction, thereby limiting the first pressure head 61. The first pressure head 61 is connected to the second pressure head 63 through a first elastic member 62, which can undergo elastic deformation in the first direction. The rotating sleeve 13, the first pressure head 61, the first elastic member 62, and the second pressure head 63 are arranged sequentially in the first direction. The push tube 53 can push the first pressure head 61 to move in the first direction near the second end 12, and then the first pressure head 61 pushes the first elastic member 62 and the second pressure head 63 to move in the first direction near the second end 12. For example, the first elastic member 62 is a spring sleeved on the first shaft 1. The second pressure head 63 is located below the first pressure head 61. The push tube 53 can push the first pressure head 61, the first elastic member 62, and the second pressure head 63 downward.

[0062] The second pressure head 63 has multiple limiting heads 64 on the side facing the intermediate sleeve 3 in the first direction, and the multiple limiting heads 64 are spaced apart in the circumferential direction. The multiple limiting heads 64 are located outside the multiple fourth ends 42 of the multiple connecting rods 4, so that the multiple limiting heads 64 limit the fourth ends 42 of the connecting rods 4 in the radial direction of the first shaft 1, and the second pressure head 63 can press the fourth ends 42 of the connecting rods 4 to rotate in the direction adjacent to the first shaft 1. Specifically, the second pressure head 63 has a pressure plate slidably connected to the fourth ends 42 of the connecting rods 4, and the multiple limiting heads 64 are provided on the side of the pressure plate facing the intermediate sleeve 3, which can be a plane or an arc surface. When the fourth ends 42 of the connecting rods 4 slide relative to the pressure plate of the second pressure head 63, the fourth ends 42 of the connecting rods 4 rotate in the direction adjacent to the first shaft 1, and the limiting heads 64 can prevent the fourth ends 42 of the connecting rods 4 from disengaging from the second pressure head 63. For example, the second pressure head 63 includes a pressure plate located at the bottom, and the lower surface of the pressure plate is provided with a plurality of limit heads 64.

[0063] In some embodiments, the first shaft 1 can drive the pressure head to rotate. Alternatively, the first shaft 1 can rotate relative to the pressure head.

[0064] In some embodiments, in a first cleaning position, a plurality of fourth ends 42 of the plurality of links 4 abut against a plurality of limiting heads 64 in a one-to-one correspondence. The limiting heads 64 have arcuate surfaces for guiding, so as to facilitate the guiding of the links 4 as they move from the first cleaning position to the second cleaning position.

[0065] In some embodiments, the second pressure head 63 has a plurality of guide holes extending through it along a first direction, and the intermediate sleeve 3 has a plurality of guide rods 31 extending along the first direction. Each guide rod 31 is slidably connected to one of the guide holes. Specifically, the cross-sections of both the guide holes and the guide rods 31 are semi-circular, and the shape of the guide rods 31 is adapted to the shape of the guide holes so that the guide rods 31 can slide within the guide holes. This allows the second pressure head 63 to easily slide relative to the intermediate sleeve 3 in the first direction. For example, the guide rods 31 slide within the guide holes in the vertical direction.

[0066] like Figure 6 As shown, in some embodiments, the intermediate sleeve 3 has a plurality of limiting holes 32 extending through it along a first direction. Specifically, the width direction of the limiting holes 32 is perpendicular to the extension direction of the first shaft 1. The openings of the limiting holes 32 are formed on both sides and the circumference of the intermediate sleeve 3 in the first direction. For example, the openings of the limiting holes 32 are formed on both sides and the circumference of the intermediate sleeve 3 in the vertical direction.

[0067] Link 4 includes a first link 43 and a second link 44, which are at an angle to each other, with the angle pointing towards the first axis 1. That is, link 4 is a curved rod that bends outward (away from the first axis 1).

[0068] The end of the first rod 43 (away from the second rod 44) ​​forms the fourth end 42, and the end of the second rod 44 (away from the first rod 43) forms the third end 41. A first rotating hole 45 is provided on the side of the first rod 43 adjacent to the connection between the first rod 43 and the second rod 44. Multiple connecting rods 4 are correspondingly located within multiple limiting holes 32, and the connecting rods 4 are hinged to the intermediate sleeve 3 through the first rotating hole 45. The fourth end 42 of the connecting rod 4 is provided with a second rotating hole 46, and the connecting rod 4 is hinged to the first connecting part 24 of the corresponding cleaning brush through the second rotating hole 46. The axes of both the first rotating hole 45 and the second rotating hole 46 are perpendicular to the first direction. Therefore, when the first shaft 1 drives the intermediate sleeve 3 to rotate, it can drive the connecting rod 4 to rotate.

[0069] A first hanging ring 47 is provided on the side of the connecting rod 4 facing away from the first shaft 1. The first hanging ring 47 is connected to the second connecting part 25 of the cleaning brush via a second elastic member 48. The first connecting part 24 is located on the side of the second connecting part 25 adjacent to the first shaft 1. Thus, after the connecting rod 4 moves the cleaning brush to the second cleaning position, the second elastic member 48 contracts to change the orientation of the cleaning surface of the cleaning brush. For example, the second elastic member 48 is a spring.

[0070] like Figures 1 to 4As shown, in some embodiments, the drive unit includes a first magnetic element 14, which is disposed at the second end 12 of the first shaft 1. The first magnetic element 14 can use magnetic force to move the cleaning brush from a second cleaning position to a first cleaning position. Specifically, the first magnetic element 14 is an electromagnet, and each cleaning brush has a second magnetic element 23 on the side facing away from the cleaning surface. When the electromagnet is energized, it can use magnetic force to attract the second magnetic element 23. Thus, the first magnetic element 14 can use magnetic force to move the cleaning brush from the second cleaning position to the first cleaning position. For example, the first magnetic element 14 is disposed at the lower end of the first shaft 1.

[0071] like Figures 1 to 4 As shown, in some embodiments, the plurality of cleaning brushes includes a first cleaning brush 21 and a second cleaning brush 22, which are symmetrically arranged in a second direction, which is the radial direction of the first axis 1. Both the first cleaning brush 21 and the second cleaning brush 22 have a semi-circular disc structure, and both include straight edges and curved edges. For example, the first cleaning brush 21 and the second cleaning brush 22 are symmetrically arranged in the left-right direction.

[0072] In the first cleaning position, the first cleaning brush 21 and the second cleaning brush 22 are joined together such that the straight edges of the first cleaning brush 21 and the second cleaning brush 22 are in contact. In the second cleaning position, the thickness directions of the first cleaning brush 21 and the second cleaning brush 22 are both in a second direction. For example, the first cleaning brush 21 is located to the left of the second cleaning brush 22, with the straight edge of the first cleaning brush 21 being the right edge and the straight edge of the second cleaning brush 22 being the left edge. In the first cleaning position, the right edge of the first cleaning brush 21 and the left edge of the second cleaning brush 22 are joined together, the dimension of the first cleaning brush 21 and the second cleaning brush 22 in the first direction is 30 mm, and the diameter of the disc structure formed by the first cleaning brush 21 and the second cleaning brush 22 is 160 mm. In the second cleaning position, the thickness directions of the first cleaning brush 21 and the second cleaning brush 22 are both in a left-right direction.

[0073] Controlled by an electromagnet, when energized, the first cleaning brush 21 and the second cleaning brush 22 are clamped together in a planar position for machining the cylinder bottom. The CNC system is then instructed to disconnect the electromagnet. At this point, under the action of the second elastic element 48, the first and second cleaning brushes 21 and 22 rotate 50° around the connecting rod 4. The push tube 53 then pushes the first pressure head 61, which in turn drives the first elastic element 62 to press down on the second pressure head 63. This, in turn, drives the connecting rod 4 to rotate, achieving the rotation of the first and second cleaning brushes 21 and 22, ultimately achieving a 90° rotation of both sides. The CNC system then issues a rotation command, which, via a servo motor, drives a reduction gear to control the rotation of the rotating sleeve, initiating the rust removal process.

[0074] In some embodiments, the first magnetic element 14 is a cylinder extending along a third direction, which is the radial direction of the first axis 1 and is perpendicular to the second direction. For example, the first magnetic element 14 is a cylinder extending in a front-rear direction.

[0075] The second magnetic component 23 includes a first magnetic sleeve 231 and a second magnetic sleeve 232. The first magnetic sleeve 231 is located on the side of the first cleaning brush 21 facing away from the cleaning surface, and the second magnetic sleeve 232 is located on the side of the second cleaning brush 22 facing away from the cleaning surface. Both the first magnetic sleeve 231 and the second magnetic sleeve 232 are made of magnets. In the first cleaning position, the first magnetic sleeve 231 and the second magnetic sleeve 232 define a mating groove with an opening facing the first magnetic component 14. The mating groove is an arc groove extending in a third direction, and the inner wall surface of the mating groove is adapted to the outer surface of the first magnetic component 14. Specifically, both the first magnetic sleeve 231 and the second magnetic sleeve 232 have grooves. When the cleaning brushes (first cleaning brush 21 and second cleaning brush 22) need to move from the second cleaning position to the first cleaning position, the first magnetic component 14 is energized to generate magnetic force so as to use magnetic force to attract the second magnetic component 23 (first magnetic sleeve 231 and second magnetic sleeve 232). Furthermore, after the first magnetic sleeve 231 and the second magnetic sleeve 232 reach the first cleaning position, they can be assembled to form a mating groove.
