Description

Technical Field

[0001] This utility model belongs to the field of reaming hole guiding technology, specifically relating to a reamer guide device for flange connection reaming holes. Background Technology

[0002] Flanges are the main connecting components in the connection process of shafts or pipes. In bearing or pipe connections, flanges are usually fixedly installed at the ends of shafts or pipes, and the two shafts or pipes are connected together using flanges and bolts. However, in some construction scenarios, such as in coupling connections, because the positions of the two shafts are fixed, there may be a slight misalignment in the relative positions of the bolt holes on the flanges during flange connection, preventing the bolts from entering the corresponding holes on the two flanges. In such cases, a reamer is usually used to enlarge the hole size so that the bolts can enter the corresponding holes on the two flanges. However, currently, reaming operations are often performed by operators using a direct reaming method. Due to the lack of reamer guidance, this can easily lead to reamer seizing or breaking, making on-site reaming operations inconvenient. Utility Model Content

[0003] This utility model provides a reamer guide device for flange connection reaming, which aims to solve the problem of inconvenient reaming operation when flanges need to be reamed during connection in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a reamer guide device for flange connection reamer holes, comprising: Two semicircular rings are provided, which are detachably connected and used to fix the pipe or shaft to one side of the flange. A movable seat is mounted on the semicircular ring, and its position on the semicircular ring has a degree of freedom to be adjusted circumferentially along the semicircular ring. A guide sleeve is mounted on the movable seat, and the guide sleeve can be moved to a position coaxial with the through hole on the flange.

[0005] In one possible implementation, both ends of the two semicircular rings are bent and provided with connecting plates, and the connecting plates are provided with through holes for connecting to the connecting plates on the opposite semicircular rings.

[0006] In one possible implementation, the movable seat includes two locking plates that are slidably disposed on the sides of the semicircular ring, and a tensioning assembly for pulling the two locking plates tight onto the semicircular ring is disposed between the two locking plates.

[0007] In one possible implementation, the tensioning component includes: A pull rod is fixedly mounted on one of the card plates and extends through the other card plate; Fasteners are threadedly connected to the pull rod and abut against the outer side of the corresponding card plate.

[0008] In one possible implementation, two arc-shaped wing plates are arranged parallel to each other at a distance from the bottom of the card plate, and an arc-shaped rib is provided on the side of the semi-circular ring, which is slidably disposed between the two arc-shaped wing plates.

[0009] In one possible implementation, a collar for mounting the guide sleeve is also fixedly mounted on the card plate, and the guide sleeve is detachably mounted on the collar.

[0010] In one possible implementation, the collar is fitted onto the outside of the guide sleeve, and a plurality of clamping members are threaded onto the outer wall of the collar. The plurality of clamping members are evenly spaced along the circumference of the collar, and the ends of the clamping members are used to abut against the outer wall of the guide sleeve.

[0011] In one possible implementation, each end of a single card plate is provided with a pull rod and a corresponding through hole.

[0012] The solution shown in this application, compared with the prior art, uses two semicircular rings, both ends of which are detachably connected, for clamping and fixing to a pipe or shaft on one side of the flange. A movable seat is also installed on the semicircular ring, the position of which can be adjusted circumferentially along the ring. A guide sleeve is also installed on the movable seat, which can move with the movable seat or adjust its position independently. In this application, when reaming is required on the flange, the two semicircular rings can be fixed to a shaft or pipe on one side of the flange. The movable seat is then adjusted to the through-hole to be reamed. By adjusting the positions of the movable seat and the guide sleeve, the guide sleeve can be aligned with the through-hole on the flange. The operator can insert the reamer inside the guide sleeve and ream the hole using the guide sleeve's guidance, improving the stability of the reamer position during reaming and facilitating the reaming operation.

[0015] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Please refer to the following: Figure 1 and Figure 2 The present invention provides a reamer guide device for flange connection reamer holes. The reamer guide device for flange connection reamer holes includes a semi-circular ring 2, a movable seat 3, and a guide sleeve 4. There are two semi-circular rings 2, which are detachably connected and used to fix to a pipe or shaft on one side of the flange 1. The movable seat 3 is mounted on the semi-circular ring 2 and has the freedom to adjust its position along the circumference of the semi-circular ring 2. The guide sleeve 4 is mounted on the movable seat 3 and can be moved to a position coaxial with the through hole on the flange 1.

[0017] The flange connection reamer guide device provided in this embodiment, compared with the prior art, features two semicircular rings 2, both ends of which are detachable and connected for clamping and fixing to a pipe or shaft on one side of the flange 1. A movable seat 3 is also installed on the semicircular ring 2, the position of which can be adjusted circumferentially. A guide sleeve 4 is also installed on the movable seat 3, which can move with the movable seat 3 or adjust its position independently. In this application, when reaming is required on the flange 1, the two semicircular rings 2 can be fixed to a shaft or pipe on one side of the flange 1. The movable seat 3 is then adjusted to the through-hole to be reamed. By adjusting the positions of the movable seat 3 and the guide sleeve 4, the guide sleeve 4 can be aligned with the through-hole on the flange 1. The operator can insert the reamer inside the guide sleeve 4 and ream the hole using the guide sleeve 4's guidance, improving the stability of the reamer position during reaming and facilitating the reaming operation.

[0018] The inner ring of the semicircular ring 2 is used to fit onto the outer surface of the pipe or shaft, and the pipe or shaft is clamped between the two semicircular rings 2 by fastening the two semicircular rings 2 together.

[0019] In some embodiments, the semicircular ring 2 can be adopted as follows: Figure 2 The structure shown. See also Figure 2Both ends of the two semicircular rings 2 are bent and fitted with connecting plates 21. Each connecting plate 21 has a through hole for connecting to the connecting plate 21 on the opposite semicircular ring 2. With connecting plates 21 bent at both ends of the semicircular rings 2, when both semicircular rings 2 are installed on a pipe or shaft, the two opposite connecting plates 21 are spaced parallel to each other. Bolts and nuts can be used to tighten the connecting plates 21 on the two semicircular rings 2, thus firmly fixing both semicircular rings 2 to the pipe or shaft.

[0020] Specifically, in this embodiment, when installing the two semicircular rings 2, the positions of the two semicircular rings 2 can be adjusted so that the ends of the semicircular rings 2 are located between two adjacent through holes on the flange 1, thereby enabling the reaming operation of multiple through holes by adjusting the position of the movable seat 3.

[0021] In some embodiments, the movable seat 3 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 The movable base 3 includes two locking plates 31 slidably disposed on the sides of the semicircular ring 2, and a tensioning assembly 32 is disposed between the two locking plates 31 to tighten them onto the semicircular ring 2. Locking plates 31 are disposed on two opposite sides of the semicircular ring 2 along its axial direction, and the two locking plates 31 form a set to constitute the movable base 3. Both locking plates 31 are slidably disposed on the semicircular ring 2 along its circumference. The tensioning assembly 32 tightens the two locking plates 31 onto the semicircular ring 2, thereby fixing the two locking plates 31 to the semicircular ring 2.

[0022] Specifically, in this embodiment, when it is necessary to adjust the position of the movable seat 3 on the semi-circular ring 2, the position of the semi-circular ring 2 can be adjusted by loosening the tightening component. After the position adjustment is completed, the position of the movable seat 3 is fixed by tightening the component.

[0023] In some embodiments, the tensioning component 32 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 The tensioning assembly 32 includes a pull rod 321 and a fastener 322. The pull rod 321 is fixedly mounted on one of the clamping plates 31 and passes through the other clamping plate 31; the fastener 322 is threadedly connected to the pull rod 321 and abuts against the outer side of the corresponding clamping plate 31. The pull rod 321 is mounted on the side wall of the clamping plate 31. The pull rod 321 is a screw, and a through hole for mounting the pull rod 321 is provided on the opposite clamping plate 31. The fastener 322 is a nut, and the two clamping plates 31 can be tightened by rotating the fastener 322.

[0024] Specifically, in this embodiment, when the movable base 3 is installed onto the semi-circular ring 2, two retaining plates 31 can be installed onto two opposite side walls of the semi-circular ring 2, and the pull rod 321 on one retaining plate 31 can be inserted into the through hole on the opposite retaining plate 31. After the position adjustment is completed, the movable base 3 is finally installed on the semi-circular ring 2 by tightening the fastener 322. The structure is simple and the operation is convenient.

[0025] In some embodiments, the aforementioned card plate 31 may employ, as follows: Figure 2 The structure shown. See also Figure 2 The bottom of the clamping plate 31 has two parallel arc-shaped wing plates 311 spaced apart. An arc-shaped rib 22, slidably positioned between the two arc-shaped wing plates 311, is located on the side of the semi-circular ring 2. The two arc-shaped wing plates 311 form an arc-shaped groove for mounting the arc-shaped rib 22. The arc-shaped rib 22 is slidably positioned inside the arc-shaped groove, and the clamping plate 31 can slide along the circumference of the arc-shaped rib 22 through the arc-shaped groove, thereby adjusting the position of the clamping plate 31. Simultaneously, the two arc-shaped wing plates 311 also limit the installation position of the clamping plate 31. When the two clamping plates 31 are installed on the semi-circular ring 2, the arc-shaped rib 22 is engaged between the two arc-shaped wing plates 311, thus limiting the movement of the clamping plate 31 to only the circumference of the semi-circular ring 2. When the two clamping plates 31 are tightened and fixed to the semi-circular ring 2 by the tensioning assembly 32, the stability of the connection position between the clamping plates 31 and the semi-circular ring 2 can be improved, thereby ensuring the stability of the installation position of the guide sleeve 4.

[0026] Preferably, in this embodiment, there is a sufficient sliding gap between the arc-shaped rib 22 and the two arc-shaped wing plates 311 to prevent the semi-circular ring 2 from affecting the movement of the movable seat 3 on the semi-circular ring 2 after it is tightened and deformed.

[0027] In some embodiments, the guide sleeve 4 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 A collar 5 for mounting the guide sleeve 4 is also fixedly installed on the clamping plate 31. The guide sleeve 4 is detachably mounted on the collar 5. The inner diameter of the collar 5 is larger than the outer diameter of the guide sleeve 4. The two ends of the guide sleeve 4 are located inside the corresponding collars 5 on two opposite clamping plates 31. Furthermore, the guide sleeve 4 is detachably mounted inside the collars 5, allowing it to be removed from the moving base 3 for replacement.

[0028] Specifically, in this embodiment, different flanges 1 will have through holes of different sizes in actual application, so that guide sleeves 4 with different inner holes can be replaced according to the size of the reamer used on site. At the same time, the guide sleeve 4 is a wear part, and the guide sleeve 4 can be detachably installed on the movable base 3, which can facilitate the replacement of the guide sleeve 4 with a new one after it wears out.

[0029] In some embodiments, the collar 5 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 A collar 5 is fitted onto the outside of the guide sleeve 4, and multiple tightening members 51 are threaded onto the outer wall of the collar 5. These tightening members 51 are evenly spaced along the circumference of the collar 5, and their ends abut against the outer wall of the guide sleeve 4. Multiple tightening members 51, which are bolts, are threaded onto the side wall of the collar 5 and penetrate through it. Preferably, three tightening members 51 are threaded onto a single collar 5, and these three tightening members 51 are evenly spaced along the circumference of the collar 5. These three tightening members 51 can fix the guide sleeve 4 inside the collar 5. Simultaneously, the position of the guide sleeve 4 inside the collar 5 can be adjusted by adjusting the position of the three tightening members 51.

[0030] Preferably, in this embodiment, during actual application, the clamping member 51 is first loosened, and then the reamer is inserted into the guide sleeve 4. After the reamer is aligned with the through hole on the flange 1, the guide sleeve 4 is then fixed into the collar 5 by the clamping member 51. This facilitates adjustment of the position of the guide sleeve 4.

[0031] In some embodiments, the aforementioned card plate 31 may employ, as follows: Figure 2 The structure shown. See also Figure 2 Each clamping plate 31 has a pull rod 321 and a corresponding through hole at both ends. When the clamping plate 31 is installed on the semi-circular ring 2, the pull rods 321 and through holes on the same clamping plate 31 are arranged at intervals along the circumference of the semi-circular ring 2. This allows clamping plates 31 of the same specification to be installed on both sides of the semi-circular ring 2. All clamping plates 31 are of the same specification, which facilitates the subsequent production and replacement of the clamping plates 31.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
