In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0035] Since the flange nut usually has four mounting holes arranged at intervals in the circumferential direction, the disassembly tool needs to insert four pins into the four mounting holes respectively, and then the disassembly tool is rotated to realize the disassembly of the flange nut on the front cutter disc. The positions of the four pins of the existing flange nut disassembly tool usually remain fixed, and it is impossible to disassemble and assemble flange nuts of different sizes, and the versatility is poor.

[0036] To solve the above problems, Figure 1 and Figure 2As shown, this embodiment proposes a flange nut disassembly and assembly tool, which includes a faceplate 1, a guide plate 2 and at least two clamping parts 3. The upper surface of the faceplate 1 is provided with at least two diameter-reducing arc grooves 11 spaced apart in the circumferential direction. The guide plate 2 is arranged on the upper surface of the faceplate 1. The guide plate 2 is provided with at least two slide grooves 21 spaced apart in the circumferential direction. The slide grooves 21 extend along the radial direction of the guide plate 2 and are connected to the diameter-reducing arc grooves 11 one by one. The clamping parts 3 include a clamping arm 31 and a needle rod 32 mounted on the clamping arm 31. The clamping arm 31 of each clamping part 3 is slidably arranged in the opposite slide groove 21 and the diameter-reducing arc groove 11 in sequence. The faceplate 1 can rotate relative to the guide plate 2 about the axial direction, so that the diameter-reducing arc groove 11 drives the corresponding clamping arm 31 to slide in the slide groove 21 and the at least two needle rods 32 are close to or away from each other. In this embodiment, the rotating faceplate 1 rotates around its axis relative to the guide disk 2, and drives the clamping arm 31 to slide in the corresponding slide groove 21 through the variable diameter arc groove 11, so that the clamping part 3 moves along the radial direction of the guide disk 2, thereby adjusting the spacing between the needle rods 32, and realizing the variable diameter adjustment of the virtual circle where the needle rods 32 are located, so that the needle rods 32 can be inserted into the mounting holes of flange nuts of different sizes, so as to realize the disassembly and assembly operations of flange nuts of different sizes, thereby improving the versatility of the disassembly and assembly tools of the flange nuts. At the same time, the structure of the disassembly and assembly tools of the flange nuts is simple, and the variable diameter adjustment operation of the virtual circle where the needle rods 32 are located is simple and easy, thereby improving the adjustment efficiency. It should be noted that the different sizes of the above-mentioned flange nuts refer to the different diameter sizes of the virtual circle where the mounting holes on the flange nuts are located.

[0037] It should be noted that the flange nut is generally provided with four mounting holes along the circumferential direction and the centers of the four mounting holes are on the same virtual circle. Therefore, the disassembly and assembly tool of the flange nut of the present embodiment is provided with four clamping parts 3, four intersecting variable diameter arc grooves 11 are correspondingly provided on the faceplate 1, and four slide grooves 21 intersecting in a cross shape are provided on the guide plate 2. By adjusting the diameter of the virtual circle where the four needle rods 32 are located, the four needle rods 32 are respectively inserted into the corresponding mounting holes, and then the disassembly and assembly operation of the flange nut on the front blade disc is realized by screwing the disassembly and assembly tool of the flange nut. Of course, in other embodiments, the clamping parts 3 can also be two, three or more than five, as long as the number of the needle rods 32 is the same as that of the mounting holes and they are plugged in one-to-one.

[0038] In this embodiment, one end of at least two variable diameter arc grooves 11 intersects at the center of the faceplate 1, and one end of at least two slide grooves 21 intersects at the center of the guide plate 2. The center of the faceplate 1 and the center of the guide plate 2 are located on the same axis and are connected. Figure 1 and Figure 2In the direction indicated by the middle arrow, when the face disk 1 rotates in the clockwise direction indicated by the arrow, the four reducing arc grooves 11 drive the clamping part 3 to move along the reducing arc grooves 11 toward the center of the face disk 1, while the clamping part 3 also moves in the slide groove 21 along the radial direction of the guide disk 2 toward the center of the guide disk 2, so that the diameter of the virtual circle where the four needle rods 32 are located becomes smaller; when the face disk 1 rotates in the counterclockwise direction indicated by the arrow, the four reducing arc grooves 11 drive the clamping part 3 to move along the reducing arc grooves 11 away from the center of the face disk 1, while the clamping part 3 also moves in the slide groove 21 along the radial direction of the guide disk 2 toward the center of the guide disk 2, so that the diameter of the virtual circle where the four needle rods 32 are located becomes larger, thereby realizing the reducing adjustment of the virtual circle where the needle rods 32 are located to adapt to flange nuts of different sizes.

[0039] like Figure 2 and Figure 3 As shown, the clamping arm 31 includes a round rod portion and a flat plate portion, and the top of the round rod portion is provided with a flat plate portion, so that the clamping arm 31 is L-shaped. The circumference of the round rod portion has two connected V-shaped inclined surfaces 312. When the faceplate 1 rotates in the clockwise direction as indicated by the arrow, the clamping member 3 moves in the slide groove 21 along the radial direction of the guide disk 2 toward the center of the guide disk 2 until the four clamping arms 31 abut against each other, and the two inclined surfaces 312 between two adjacent clamping arms 31 are close to each other. At this time, the diameter of the virtual circle where the four needle rods 32 are located is the smallest.

[0040] like Figure 3 As shown, the needle rod 32 includes a connecting rod 321 and a rod sleeve 322. One end of the connecting rod 321 is mounted on the clamping arm 31, and the other end of the connecting rod 321 protrudes from the upper surface of the clamping arm 31. The outer diameters of the plurality of rod sleeves 322 are different, and one of the rod sleeves 322 is detachably mounted on the other end of the connecting rod 321. By setting the needle rod 32 as a split structure of the connecting rod 321 and the rod sleeve 322, the rod sleeves 322 with different outer diameters can be selectively mounted on the connecting rod 321, so that the needle rod 32 has different outer diameters to adapt to flange nuts of different sizes, further improving the versatility of the flange nut disassembly and assembly tool.

[0041] Furthermore, the rod sleeve 322 is provided with a mounting groove running through one end thereof in the axial direction, and the other end of the connecting rod 321 is passed through and detachably mounted in the mounting groove. The rod sleeve 322 is sleeved on the connecting rod 321 through the mounting groove, which facilitates the rapid assembly of the connecting rod 321 and the rod sleeve 322, and improves the structural strength of the needle rod 32.

[0042] In this embodiment, the connecting rod 321 is threadedly connected to the installation groove. The inner wall of the installation groove is provided with an internal thread, and the other end of the connecting rod 321 protruding from the clamping arm 31 is screwed and installed in the installation groove, so that the assembly operation of the connecting rod 321 and the rod sleeve 322 is simple and easy, ensuring the detachable installation of the connecting rod 321 and the rod sleeve 322, and improving the disassembly efficiency of the connecting rod 321 and the rod sleeve 322.

[0043] like Figure 1 to Figure 3 As shown, the clamping arm 31 is provided with a plurality of positioning holes 311 spaced apart along the radial direction of the guide plate 2, and the needle rod 32 is detachably installed in one of the positioning holes 311. By providing a plurality of positioning holes 311, the installation position of the needle rod 32 on the clamping arm 31 can be flexibly adjusted, thereby further adjusting the diameter of the virtual circle where the four needle rods 32 are located, expanding the diameter change range of the virtual circle where the four needle rods 32 are located, and further improving the versatility of the disassembly and assembly tool of the flange nut. Specifically, one end of the connecting rod 321 can be installed in the positioning hole 311 by snap connection or threaded connection.

[0044] like Figure 2 and Figure 4 As shown, the face disc 1 is provided with a guide groove 12 along the circumferential direction, and the guide groove 12 runs through both ends of the axial direction of the face disc 1. The disassembly and assembly tool of the flange nut also includes a guide rod 4, one end of which passes through the guide groove 12 and is connected to the guide disc 2. When the face disc 1 rotates relative to the guide disc 2 around its axial direction, the guide rod 4 slides relatively in the guide groove 12. Through the sliding cooperation between the guide rod 4 and the guide groove 12, the rotation process of the face disc 1 relative to the guide disc 2 is guided and limited, thereby improving the stability and reliability of the face disc 1 during rotation, and avoiding the situation where the eccentric misalignment between the face disc 1 and the guide disc 2 causes the clamp 3 to be stuck.

[0045] The four variable diameter arc grooves 11 on the flower disc 1 of this embodiment divide the upper surface of the flower disc 1 into four petal parts, and there is a petal part between two adjacent variable diameter arc grooves 11. A guide groove 12 is provided on each petal part, and four guide rods 4 are correspondingly installed on the guide disc 2, which further improves the stability and reliability of the flower disc 1 when rotating. Of course, in other embodiments, the number of guide grooves 12 and guide rods 4 can also be other numbers, which are not specifically limited here.

[0046] Specifically, the other end of the guide rod 4 extends out of the face disc 1 and is provided with a stopper, which is used to stop the face disc 1 from moving axially away from the guide disc 2. The stopper of the guide rod 4 is used to unidirectionally limit the face disc 1 in the axial direction to ensure a reliable connection between the face disc 1 and the guide disc 2. The guide rod 4 of this embodiment is a screw rod, the rod portion of the screw rod passes through the guide groove 12 and is threadedly connected to the guide disc 2, and the head of the screw rod extends out of the face disc 1 and abuts against the side of the face disc 1 away from the guide disc 2.

[0047] like Figure 2 and Figure 4 As shown, the flange nut disassembly and assembly tool also includes a locking member 5, which is movably mounted on the faceplate 1 and / or the guide plate 2 to lock the faceplate 1 or the guide plate 2. When the faceplate 1 is rotated into position relative to the guide plate 2, the locking member 5 locks the faceplate 1 and the guide plate 2 to fix the positions of the four needle rods 32. The locking member 5 of this embodiment can be installed on the faceplate 1, the guide plate 2, or both, as long as it can lock the faceplate 1 and the guide plate 2.

[0048] Specifically, the face plate 1 is provided with a locking hole 13 along the axial direction, and the locking member 5 is movably arranged in the locking hole 13 and can tighten or loosen the guide plate 2. The locking member 5 locks the face plate 1 and the guide plate 2 by abutting against each other, which is easy to operate and is conducive to improving the adjustment efficiency. The locking member 5 of this embodiment is a top screw, and the top screw is threadedly connected in the locking hole 13. In other embodiments, the locking member 5 can also be a screw, a pin or other components, as long as it can lock the face plate 1 and the guide plate 2. In this embodiment, when it is necessary to adjust the diameter of the virtual circle where the needle rod 32 is located, the top screw retracts into the locking hole 13 and disengages from the guide plate 2, so that the face plate 1 can rotate relative to the guide plate 2 around its axial direction; when the needle rod 32 is adjusted to the right position, the top screw is screwed so that the top screw extends out of the locking hole 13 and tightens the guide plate 2 (at this time, the face plate 1 is pressed against the stopper), the face plate 1 and the guide plate 2 are locked, and the subsequent disassembly and assembly operation of the flange nut can be performed.

[0049] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
