[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The core of this application is to provide a guide sleeve that is easy to replace. Another core aspect of this application is to provide a guiding mechanism including the aforementioned guide sleeve. Yet another core aspect of this application is to provide a processing device including the aforementioned guiding mechanism.

[0033] This application provides a guide sleeve, including a fastening assembly 3, a transition sleeve 1, and a plurality of first guide sleeves 2; wherein, the transition sleeve 1 is used to be inserted into the guide sleeve seat of the processing equipment, and the transition sleeve 1 has a receiving hole; the first guide sleeve 2 has a first guide hole for inserting a processing tool, and the diameters of the first guide holes of the plurality of first guide sleeves 2 are not equal; the first guide sleeve 2 can be inserted into or removed from the receiving hole of the transition sleeve 1, the fastening assembly 3 can fasten or loosen the transition sleeve 1 and the first guide sleeve 2, and the plurality of first guide sleeves 2 can be selectively inserted into the receiving hole.

[0034] Specifically, such as Figure 1 As shown, the transition sleeve 1 adopts a sleeve structure with a receiving hole extending along its own axis, and the first guide sleeve 2 adopts a sleeve structure with a first guide hole extending along its own axis. The guide sleeve is equipped with several first guide sleeves 2, such as two or three, and the diameters of the first guide holes of the several first guide sleeves 2 are not equal. The first guide sleeve 2 can be inserted into the receiving hole of the transition sleeve 1 and has a clearance fit with the transition sleeve 1, so that the first guide sleeve 2 can be detached from the transition sleeve 1. In addition, a fastening component 3 is provided to fasten the transition sleeve 1 and the first guide sleeve 2. After the guide sleeve is installed on the processing equipment, it can position and guide the processing tool. By adjusting the fastening component 3, the transition sleeve 1 and the first guide sleeve 2 can be loosened to facilitate the replacement of the first guide sleeve 2. The replacement of the guide sleeve is relatively easy.

[0035] When the guide sleeve needs to be installed, first insert the transition sleeve 1 into the guide sleeve seat of the machining tool, then insert the matching first guide sleeve 2 selected according to the diameter of the hole to be processed into the receiving hole of the transition sleeve 1, and finally connect the transition sleeve 1 and the first guide sleeve 2 through the fastening assembly. When the first guide sleeve 2 needs to be replaced, first adjust the fastening assembly 3 to loosen the transition sleeve 1 and the first guide sleeve 2, then pull out the first guide sleeve 2 that needs to be replaced inserted in the transition sleeve 1, then insert the first guide sleeve 2 that needs to be used in subsequent processing into the receiving hole, and reconnect the transition sleeve 1 and the first guide sleeve 2 after insertion and mating through the fastening assembly 3.

[0036] It should be noted that the type of fastening component 3 is not limited, as long as it can meet the above functions. For example, the fastening component 3 includes a double-ended lead screw and a fastening nut. The transition sleeve 1 has two first positioning holes and two second positioning holes, and the center lines of the two first positioning holes are collinear. The center lines of the two second positioning holes are also collinear, and both the first and second positioning holes extend along the chord direction of the transition sleeve 1. Correspondingly, the first guide sleeve 2 has a third positioning hole and a fourth positioning hole, and both the third and fourth positioning holes extend along the chord direction of the first guide sleeve 2. When the first guide sleeve 2 is inserted into the transition sleeve 1, the center line of the third positioning hole is collinear with the center line of the first positioning hole, and the center line of the fourth positioning hole is collinear with the center line of the second positioning hole. One double-ended lead screw is inserted into the first and third positioning holes, and the other double-ended lead screw is inserted into the second and fourth positioning holes. Fastening nuts are threaded to both ends of the two double-ended lead screws, and both the first and second positioning holes are countersunk holes. The fastening nuts are inserted into the corresponding first or second positioning holes.

[0037] In some embodiments, the guide sleeve is an oil feeder, or in other embodiments, the guide sleeve is a hollow seat.

[0038] Based on the above embodiments, the guide sleeve further includes several second guide sleeves, each having a second guide hole for inserting a machining tool. The second guide sleeves and transition sleeve 1 can be selectively inserted into the guide sleeve seat of the machining equipment, and the diameter of each second guide hole is larger than the diameter of the first guide hole of each first guide sleeve 2.

[0039] Specifically, in this embodiment, in addition to the transition sleeve 1 and several first guide sleeves 2, several second guide sleeves are also provided. The second guide sleeves have second guide holes extending along their own axial direction, and the diameter of the second guide hole of each second guide sleeve is larger than the diameter of the first guide hole of each first guide sleeve 2. When the processing equipment needs to process a channel within its own diameter range that is close to or equal to the maximum limit diameter, it only needs to select the second guide sleeve with the corresponding inner diameter to insert the tool. When the processing equipment needs to process a channel within its own diameter range that is close to or equal to the minimum limit diameter, it uses the transition sleeve 1 and selects the first guide sleeve 2 with the corresponding inner diameter to insert the tool. That is, when it needs to process a channel with a smaller diameter, it only needs to select and use the transition sleeve 1 and the corresponding first guide sleeve 2. The processing equipment can achieve the positioning and guidance of the processing tool through the insertion and cooperation of the transition sleeve 1 and the first guide sleeve 2. When it needs to process a channel with a larger diameter, it only needs to select and use the second guide sleeve. The processing equipment can achieve the positioning and guidance of the processing tool through the second guide sleeve. This design helps to reduce the difficulty of replacing the guide sleeve while avoiding the use of the thin-walled transition sleeve 1 and the first guide sleeve 2, thus effectively improving the reliability of the guide sleeve.

[0040] Based on the above embodiments, the number of transition sleeves 1 is greater than or equal to two, and the diameters of the receiving holes of the several transition sleeves 1 are not equal; the first guide sleeve 2 can be inserted into or withdrawn from the receiving hole of the corresponding transition sleeve 1, and several first guide sleeves 2 can be selectively inserted into the receiving hole of the corresponding transition sleeve 1, and several transition sleeves 1 can be selectively inserted into the guide sleeve seat.

[0041] Specifically, in this embodiment, a number of transition sleeves 1 with different diameter receiving holes are provided, such as two or three, and a corresponding first guide sleeve 2 that can be clearance-fitted to each transition sleeve 1 with different diameter receiving holes is provided. When a smaller diameter channel needs to be processed, a transition sleeve 1 with a smaller diameter receiving hole can be selected, and when a larger diameter channel needs to be processed, a transition sleeve 1 with a larger diameter receiving hole can be selected. After selecting the transition sleeve 1, the corresponding first guide sleeve 2 can be selected according to the diameter of the receiving hole and the diameter of the channel to be processed. With this setting, the volume and weight of the transition sleeve 1 and the first guide sleeve 2 can be distributed more evenly, so as to further reduce the assembly difficulty.

[0042] For example, in some specific embodiments, the processing equipment can process holes with a diameter range of 35-200mm. There are two transition sleeves 1 and one second guide sleeve. One transition sleeve 1 has a receiving hole diameter of 100mm, the other transition sleeve 1 has a receiving hole diameter of 170mm, and the second guide sleeve has a second guide hole diameter of 185mm. In use, when processing holes with a diameter less than or equal to 90mm, the transition sleeve 1 with a receiving hole diameter of 100mm is selected. When processing holes with a diameter less than or equal to 160mm but greater than 90mm, the transition sleeve 1 with a receiving hole diameter of 170mm is selected. The first guide sleeve 2 is selected according to the inner diameter of the hole to be processed. When processing holes with a diameter greater than 160mm, a suitable second guide sleeve is selected according to the inner diameter of the hole to be processed.

[0043] Based on the above embodiment, the receiving hole is a stepped hole, and the stepped position of the transition sleeve 1 has a plurality of fastening threaded holes 11; the first guide sleeve 2 has a flange structure 21, and the flange structure 21 has a plurality of fastening through holes 211; the fastening component 3 includes a plurality of bolts 31, and the plurality of bolts 31 can be inserted into the corresponding fastening through holes 211 and fastening threaded holes 11.

[0044] Specifically, such as Figure 1As shown, the receiving hole of the transition sleeve 1 is a stepped hole, and the diameter of the left side of the receiving hole is larger than the diameter of the right side of the receiving hole. Correspondingly, the left end of the first guide sleeve 2 has an annular flange structure 21, and three or four equal numbers of fastening through holes 211 are opened on the flange structure 21. In use, the transition sleeve 1 is inserted into the guide sleeve seat of the processing equipment, and the first guide sleeve 2 is inserted into the receiving hole of the transition sleeve 1, so that the fastening through holes 211 on the first guide sleeve 2 are aligned with the corresponding fastening threaded holes 11 on the transition sleeve 1, so that the bolt 31 can be inserted into them, thereby realizing the fastening connection between the transition sleeve 1 and the first guide sleeve 2. With this setting, the structure of the guide sleeve is simple and easy to assemble and disassemble.

[0045] Of course, the guide sleeve is not limited to the types mentioned above. Any type that reduces the difficulty of replacement while avoiding impact on the machining of the borehole can be used, for example, as shown in the reference. Figure 1 As shown, the outer diameter of the flange structure 21 is equal to the outer diameter of the left end of the transition sleeve 1, and the flange structure 21 of the first guide sleeve 2 abuts against the left end face of the transition sleeve 1. Then, after the transition sleeve 1 and the first guide sleeve 2 are inserted and matched, the left end of the guide sleeve is a straight cylindrical structure with equal diameter.

[0046] Based on the above embodiments, the flange structure 21 has a plurality of ejector threaded through holes 212.

[0047] Specifically, such as Figure 1 As shown, a threaded through hole 212 extending axially along the first guide sleeve 2 is provided on the flange structure 21. When the first guide sleeve 2 needs to be removed from the transition sleeve 1, all bolts 31 are unscrewed to loosen the first guide sleeve 2 and the transition sleeve 1. The threaded rod is then inserted into the threaded through hole 212. After the threaded rod abuts against the stepped surface of the transition sleeve 1, the threaded rod is continued to be screwed in to make it continue to go deeper. This will push the first guide sleeve 2 toward the outside of the receiving hole, so that the first guide sleeve 2 can be separated from the transition sleeve 1.

[0048] In some specific embodiments, there are two ejector threaded through holes 212, and the two ejector threaded through holes 212 are evenly distributed around the center line of the first guide sleeve 2. Alternatively, in other specific embodiments, there are three ejector threaded through holes 212, and the three ejector threaded through holes 212 are arranged in a triangular pattern. It should be noted that the number and distribution of ejector threaded through holes 212 are not limited, as long as the first guide sleeve 2 can be stably ejected from the receiving hole.

[0049] like Figure 1As shown, based on the above embodiment, there are two ejector threaded through holes 212 and four fastening through holes 211; the four fastening through holes 211 are evenly arranged around the center line of the first guide sleeve 2; one ejector threaded through hole 212 is located between two adjacent fastening through holes 211, and another ejector threaded through hole 212 is located between the remaining two adjacent fastening through holes 211. With this arrangement, the layout of the fastening through holes 211 and the ejector threaded through holes 212 is reasonable and the structure is more stable.

[0050] Based on the above embodiment, the fastening through hole 211 is a countersunk hole, so the tail end of the bolt 31 that fastens the transition sleeve 1 and the first guide sleeve 2 can be inserted into the fastening through hole 211, which helps to avoid the fastening component 3 from affecting the hole processing.

[0051] In some specific embodiments, the wear resistance index of the first guide sleeve 2 is higher than that of the transition sleeve 1. Specifically, the first guide sleeve 2 is made of high wear-resistant materials or has undergone post-processing. For example, the first guide sleeve 2 can be made of high-manganese steel or wear-resistant ferrochrome steel, or a steel structure that has undergone quenching treatment, in order to extend the service life of the guide sleeve. The transition sleeve 1 is made of conventional materials, such as cast iron, in order to reduce the manufacturing cost of the guide sleeve.

[0052] In some specific embodiments, the inner wall of the first guide sleeve 2 is coated with a surface reinforcement layer, such as a laser cladding layer or a copper infiltration layer, to improve the wear resistance of the inner surface of the first guide sleeve 2.

[0053] It should be noted that the external shape and structure of the transition sleeve 1 and its mating structure with the guide sleeve can be referred to the corresponding structure of the guide sleeve in related technologies, and will not be described in detail in this application.

[0054] In addition to the guide sleeve described above, this application also provides a guide mechanism including the guide sleeve disclosed in the above embodiments, and a processing device including the above guide mechanism. The processing device can be a drilling machine, a reaming machine, or a boring machine, etc. For the structure of the other parts of the guide mechanism and the processing device, please refer to the prior art, which will not be described in detail here.
