Description

Technical Field

[0001] This invention relates to the field of engineering machinery, and specifically to a bearing assembly method for a mobile boring machine. Background Technology

[0002] Because large equipment is difficult to move, repairing and processing it requires on-site operation, necessitating the use of on-site processing equipment. Chinese patent application number 201210570292.3, published on May 1, 2013, discloses a boring device. This device includes a tool holder fixing seat, a tool holder, a tool feed mechanism, and a transmission mechanism. The tool holder is equipped with a boring tool, which passes through and is supported on the tool holder fixing seat. The tool holder is connected to the transmission mechanism, which rotates the tool holder. The tool feed mechanism is connected to the tool holder fixing seat and the tool holder, and is used to advance the tool holder.

[0003] The boring machine's tool holder mounting base is equipped with an adjusting ring, which includes a ring body and an adjusting bolt. The adjusting bolt is located in the adjusting screw hole of the ring body, and the adjusting ring is fitted onto the tool holder mounting base. The coaxiality between the tool holder mounting base and the ear plate hole is adjusted by the adjusting bolt. However, the position of the tool holder mounting base is locked solely by the adjusting bolt, resulting in poor connection stability between the adjusting ring and the tool holder mounting base. When the tool holder moves, the vibration generated by the tool holder is transmitted to the tool holder mounting base, easily causing displacement. Furthermore, the range of motion of the tool holder mounting base is limited by moving only through the adjusting ring. Meanwhile, the adjusting ring is directly welded to the outside of the ear plate, which requires cutting off the weld between the adjusting ring and the outside of the ear plate when disassembling the adjusting ring, making the operation cumbersome. In addition, one end of the tool holder is connected to the adjusting ring, and the other end of the tool holder is connected to the feeding mechanism and the transmission mechanism. The two ends of the tool holder are subjected to force separately, which will cause the force on the two ends of the tool holder to be inconsistent. Along the length of the tool holder, the horizontal height of the two ends of the tool holder will change, causing the axis of the tool holder to change. Consequently, the axis of the tool holder and the axis of the ear plate boring hole cannot be kept in the same straight line. Summary of the Invention

[0004] This invention provides a bearing assembly method for a mobile boring machine. The detachable connection between the mounting plate and the equipment to be processed prevents damage to the mounting plate during assembly and disassembly. By changing the position of the support plate on the mounting plate, the position of the bearing seat is adjusted, and the end face of the bearing seat does not directly contact the mounting plate, thus reducing wear on the bearing seat.

[0005] To achieve the above objectives, the technical solution of the present invention is: a bearing assembly method for a mobile boring machine, which is realized by a support assembly. The support assembly includes a mounting plate, a support plate, and a bearing housing. A bearing is provided in the bearing housing. Two or more fixing parts are provided on the mounting plate, and fixing holes are provided on the fixing parts.

[0006] The bearing assembly method for a moving boring machine includes the following steps:

[0007] S1. Weld threaded posts onto the equipment to be processed, then fit the fixing holes of the mounting plate onto the threaded posts and fix the position of the mounting plate with nuts.

[0008] S2. Install the bearing housing onto the support plate.

[0009] S3. Insert the bearing housing through the first through hole in the mounting plate.

[0010] S4. Determine the position of the hole to be bored.

[0011] S5. Adjust the positioning bolts and move the support plate. When the bearing axis in the bearing housing is aligned with the position of the hole to be bored, fix the position of the bearing housing with the positioning bolts.

[0012] S6. Install the locking assembly on the second connecting hole of the support plate and the first connecting hole of the mounting plate; the locking assembly fixes the support plate to the mounting plate.

[0013] The above method first fixes the mounting plate to the equipment to be processed. The mounting plate is then detachably connected to the equipment via fixing holes, bolts, and nuts, preventing damage during installation and removal. Next, the through-hole mates with the second through-hole, fixing the bearing housing to the support plate. Then, the through-hole mates with the first through-hole, connecting the bearing housing to the support plate and mounting plate. Positioning bolts are then installed, and the position of the support plate is adjusted. The support plate moves the bearing housing, and the length of the three positioning bolts extending into the through-holes is adjusted to allow the bearing housing to move radially within the through-holes. This method is simple. Once the bearing's axis in the bearing housing is aligned with the boring hole, the positioning bolts provide initial fixation. Finally, locking components are installed on the mounting plate and support plate, indirectly fixing the bearing housing by securing the support plate.

[0014] The positioning component is arranged along the radial direction of the first through hole and fixes the bearing housing along the radial direction of the bearing housing. The locking component is arranged along the axial direction of the first through hole and fixes the bearing housing along the axial direction of the bearing housing. This can restrict the movement of the bearing housing in both the axial and radial directions, so that the bearing housing is not easy to shift when it is used in conjunction with the tool drive shaft.

[0015] Meanwhile, the positioning and locking components only fix the bearing housing. When used in conjunction with the tool drive shaft, the tool drive shaft passes through the bearing, and the bearing housing does not need to support the transmission mechanism of the tool drive shaft, thus ensuring that the axis of the bearing housing and the axis of the boring hole are on the same straight line.

[0016] The bearing housing is moved by the support plate. The friction between the support plate and the bearing housing is small, which reduces the wear on the bearing housing and avoids the bearing housing being directly mounted on the mounting plate. When the bearing housing moves relative to the mounting plate, the large friction will cause damage to the bearing housing.

[0017] Furthermore, the fixing hole includes two or more circular holes, the mounting plate has a first through hole along the thickness direction, and two or more movably positioned positioning components are provided on the mounting plate along the radial direction of the first through hole; the positioning component includes a positioning threaded hole and a positioning bolt, the positioning threaded hole is provided on the mounting plate along the radial direction of the first through hole, the positioning bolt is provided in the positioning threaded hole, and one end of the positioning bolt extends into the first through hole.

[0018] A support plate is set on one side of the mounting plate. Two or more first connecting holes are provided on the mounting plate around the first through hole, and two or more second connecting holes are provided on the support plate around the second through hole. The first connecting holes and the second connecting holes are both arranged along the axial direction of the first through hole. A locking component is connected between the first connecting holes and the second connecting holes.

[0019] The support plate has a second through hole along the thickness direction. A clamping part is provided at one end of the bearing seat, and a through part is provided at one end of the clamping part. The clamping part is connected to the support plate. The through part passes through the second through hole and the first through hole. The positioning component contacts the through part and positions the bearing seat.

[0020] The above configuration, through the through-hole and the first through hole and the second through hole, connects the bearing housing with the support plate and the mounting plate. At the same time, the support plate is fixed to the mounting plate by the locking assembly, the through-hole of the bearing housing is directly fixed by the positioning assembly, the clamping part is connected to the support plate and the locking assembly connects the support plate and the mounting plate, and the locking assembly fixes the support plate to indirectly fix the bearing housing, thus ensuring good stability of the bearing housing.

[0021] Furthermore, the clamping part has two or more mounting holes surrounding the through-hole, and the support plate has two or more third connecting holes surrounding the second through-hole. The mounting holes are threaded holes, and the mounting holes and the third connecting holes are connected by bolts. By connecting the bolts in the third connecting holes with the threaded mounting holes, the clamping part is pressed tightly onto the support plate, and the connection between the clamping part and the support plate is reliable.

[0022] Furthermore, S2 specifically involves threading a bolt through the third connecting hole and into the mounting hole to mount the bearing housing onto the support plate. This method is simple and ensures a stable connection between the bearing housing and the support plate.

[0023] Furthermore, both the first connecting hole and the second connecting hole are waist holes, and the length direction of the first waist hole intersects with the length direction of the second waist hole.

[0024] Furthermore, after S6, it also includes:

[0025] S7. If the bearing housing position needs to be changed, proceed to S8.

[0026] S8. The locking assembly releases the connection between the support plate and the mounting plate.

[0027] S9. Adjust the positioning bolts, move the support plate, and move the locking assembly in the first and second connecting holes; after the bearing seat position is moved, proceed to S10.

[0028] S10. Position the bearing housing with positioning bolts; tighten the support plate and mounting plate again with locking components.

[0029] In the above method, the first and second connecting holes are waist holes. After the locking component is loosened, the locking component can move in the first and second connecting holes. This allows the support plate to move on the mounting plate without completely disassembling the locking component, making it convenient to use.

[0030] Furthermore, the locking assembly includes a locking nut and a locking bolt, with the locking bolt passing through a first connecting hole and a second connecting hole and connected to the locking nut.

[0031] The above setup uses a threaded connection between the locking bolt and the locking nut to press the support plate onto the mounting plate, and the friction between the support plate and the mounting plate to fix the support plate in place.

[0032] Furthermore, S8 specifically involves releasing the locking nut from the locking bolt, thus separating the support plate from the mounting plate. This operation is simple.

[0033] Furthermore, S10 specifically involves: locking the locking nut to lock the locking bolt, and the locking assembly pressing the support plate against the mounting plate. This simplifies the operation. Attached Figure Description

[0038] Figure 5 This is a flowchart of the present invention. Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1-5 As shown, a bearing assembly method for a movable boring machine is implemented through a support assembly. The support assembly includes a mounting plate 1, a support plate 5, and a bearing housing 2. A bearing (not shown in the figure) is provided in the bearing housing 2. The mounting plate 1 has a first through hole 11 along the thickness direction. Two or more positioning components 3 are provided on the mounting plate 1 along the radial direction of the first through hole 11. One end of the positioning component 3 extends into the first through hole 11. The support plate 5 is provided on one side of the mounting plate 1. A locking component 4 is connected between the support plate 5 and the mounting plate 1 along the axial direction of the first through hole 11.

[0041] The support plate 5 has a second through hole 51 along its thickness direction. A clamping part 21 is provided at one end of the bearing seat 2, and a through part 22 is provided at one end of the clamping part 21. The clamping part 21 is connected to the support plate 5. The through part 22 passes through the first through hole 11 and the second through hole 51. The bearing seat 2 is connected to the support plate 5 and the mounting plate 1 by the cooperation of the through part 22 with the first through hole 11 and the second through hole 51. At the same time, the support plate 5 is fixed to the mounting plate 1 by the locking assembly 4.

[0042] The positioning component 3 contacts the through-hole part 22 and positions the bearing housing 2. The through-hole part 22 of the bearing housing 2 is directly fixed by the positioning component 3, and the support plate 4 is connected by the clamping part 21, and the locking component 4 connects the support plate 5 and the mounting plate 1. In this way, the locking component 4 fixes the support plate 5 and indirectly fixes the bearing housing 2, resulting in good stability of the bearing housing.

[0043] The positioning component 3 is arranged along the radial direction of the first through hole 11, and the positioning component 3 fixes the bearing seat 2 along the radial direction of the bearing seat 2. The locking component 4 is arranged along the axial direction of the first through hole 11, and the locking component 4 fixes the bearing seat 2 along the axial direction of the bearing seat 2. This can restrict the movement of the bearing seat 2 in both the axial and radial directions, so that the bearing seat 2 is not easy to shift when it is used in conjunction with the tool drive shaft.

[0044] In this embodiment, three positioning components 3 are provided; the three positioning components 3 are movably set on the mounting plate 1. By adjusting the length of the end of the positioning component 3 extending into the first through hole 11, the position of the bearing seat 2 on the mounting plate 1 is adjusted; so that the bearing in the bearing seat 2 is coaxially set with the boring hole to be processed; in use, first release the locking component 4 from locking the support plate 5 and the mounting plate 1, then adjust the positioning component 3 to change the position of the bearing seat 2, and then lock the support plate 5 and the mounting plate 1 again with the locking component 4.

[0045] By setting a support plate 5, the bearing housing 2 is fixed on the support plate 5. The support plate 5 drives the bearing housing 2 to move. The friction between the support plate 5 and the bearing housing 2 is small, which reduces the wear on the bearing housing 5 and avoids the bearing housing 5 being directly set on the mounting plate 1. When the bearing housing 2 moves relative to the mounting plate 1, the large friction will cause damage to the bearing housing 2.

[0046] The mounting plate 1 has two or more first connecting holes 12 around the first through hole 11, and the support plate 5 has two or more second connecting holes 52 around the second through hole 51. The first connecting holes 12 and the second connecting holes 52 are connected by a locking assembly 4. The support plate 5 and the mounting plate 1 are connected by the cooperation of the first connecting holes 12 and the second connecting holes 52, which is a simple structure.

[0047] The clamping part 21 has two or more mounting holes 23 arranged around the through part 22, and the support plate 5 has two or more third connecting holes 53 arranged around the second through hole 51. In this embodiment, there are three mounting holes 23 and three third connecting holes 53. The mounting holes 23 are threaded holes, and the mounting holes 23 and the third connecting holes 53 are connected by bolts 6. By threading the bolts 6 through the third connecting holes 53 to the mounting holes 23, the clamping part 21 is clamped onto the support plate 1, and the connection between the clamping part 21 and the support plate 1 is reliable.

[0048] In this embodiment, both the first connecting hole 12 and the second connecting hole 52 are oblong holes, and the length direction of the first oblong hole 12 intersects the length direction of the second oblong hole 52. By setting both the first connecting hole 12 and the second connecting hole 52 as oblong holes, the locking component 4 can move within the first connecting hole 12 and the second connecting hole 52 after being released. This allows the support plate 5 to move on the mounting plate 1 without completely disassembling the locking component 4, making it convenient to use.

[0049] The locking assembly 4 includes a locking nut 42 and a locking bolt 41. The locking bolt 41 passes through the first connecting hole 12 and the second connecting hole 52 and is connected to the locking nut 42. The threaded connection between the locking bolt 41 and the locking nut 42 enables the pressing part 21 to be pressed onto the mounting plate 1, and the pressing part 21 is fixed by the friction between the pressing part 21 and the mounting plate 1.

[0050] The positioning assembly 3 includes a positioning threaded hole 31 and a positioning bolt 32. The positioning threaded hole 31 is disposed on the mounting plate 1 along the radial direction of the first through hole 11. The positioning bolt 32 is disposed in the positioning threaded hole 31, with one end of the positioning bolt 32 extending into the first through hole 11. The positioning bolt 32 is threadedly connected to the positioning threaded hole 31. By rotating the positioning bolt 32, the length of the end of the positioning bolt 32 extending into the first through hole 11 can be changed, facilitating the adjustment of the position of the bearing seat 2.

[0051] The mounting plate 1 has two or more fixing parts 13, and each fixing part 13 has a fixing hole 131. The mounting plate 1 is installed through the fixing holes 13, facilitating its use. In this embodiment, there are three fixing parts 13, and the fixing holes 131 include two or more round holes. This facilitates adjustment of the position of the mounting plate 1 at the processing location, and by movably setting the mounting plate 1 and the support plate 5, the range of motion of the bearing seat 2 is increased.

[0052] The bearing assembly method for a moving boring machine includes the following steps:

[0053] S1. Weld threaded posts onto the equipment to be processed, then fit the fixing holes of the mounting plate onto the threaded posts and fix the position of the mounting plate with nuts.

[0054] S2. Install the bearing housing onto the support plate.

[0055] S3. Insert the bearing housing through the first through hole in the mounting plate.

[0056] S4. Determine the position of the hole to be bored.

[0057] S5. Adjust the positioning bolts and move the support plate. When the bearing axis in the bearing housing is aligned with the position of the hole to be bored, fix the position of the bearing housing with the positioning bolts.

[0058] S6. Install the locking assembly on the second connecting hole of the support plate and the first connecting hole of the mounting plate; the locking assembly fixes the support plate to the mounting plate.

[0059] S7. If the bearing housing position needs to be changed, proceed to S8.

[0060] S8. The locking assembly releases the connection between the support plate and the mounting plate.

[0061] S9. Adjust the positioning bolts, move the support plate, and move the locking assembly in the first and second connecting holes; after the bearing seat position is moved, proceed to S10.

[0062] S10. Position the bearing housing with positioning bolts; tighten the support plate and mounting plate again with locking components.

[0063] The above method first fixes the mounting plate to the equipment to be processed. The mounting plate is then detachably connected to the equipment via fixing holes, bolts, and nuts, preventing damage during installation and removal. Next, the through-hole mates with the second through-hole, fixing the bearing housing to the support plate. Then, the through-hole mates with the first through-hole, connecting the bearing housing to the support plate and mounting plate. Positioning bolts are then installed, and the position of the support plate is adjusted. The support plate moves the bearing housing, and the length of the three positioning bolts extending into the through-holes is adjusted to allow the bearing housing to move radially within the through-holes. This method is simple. Once the bearing's axis in the bearing housing is aligned with the boring hole, the positioning bolts provide initial fixation. Finally, locking components are installed on the mounting plate and support plate, indirectly fixing the bearing housing by securing the support plate.

[0064] If the bearing housing position needs to be changed a second time, first release the locking assembly from locking the support plate and mounting plate, then adjust the positioning assembly to change the position of the support plate. The support plate will then move the bearing housing, and the locking assembly will then lock the support plate and mounting plate again. Because the connecting hole is a slotted hole, the locking assembly can move within the connecting hole after being released. This allows the bearing housing to be moved without completely disassembling the locking assembly, making it convenient to use.

[0065] In this embodiment, the tool drive shaft is used by passing through a bearing. When used in conjunction with the tool drive shaft, the tool drive shaft passes through the bearing, and the bearing housing does not need to support the transmission mechanism of the tool drive shaft, thereby ensuring that the axis of the bearing housing and the axis of the boring hole are on the same straight line.
