Description

Technical Field

[0001] This invention relates to the field of engineering machinery, and more specifically to a method for installing a cutting tool and a processing equipment. 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 set in the adjusting screw hole of the ring body, and the adjusting ring is sleeved on the tool holder mounting base. The coaxiality between the tool holder mounting base and the ear plate hole is adjusted by adjusting the adjusting bolt. However, the position of the tool holder mounting base is locked only by adjusting the adjusting bolt. The connection stability between the adjusting ring and the tool holder mounting base is poor. When the tool holder moves, the vibration generated by the tool holder is transmitted to the tool holder mounting base, which can easily cause the tool holder mounting base to shift. Meanwhile, the adjusting ring is directly welded to the outside of the ear plate. When disassembling the adjusting ring, the weld between the adjusting ring and the outside of the ear plate needs to be cut off, which is cumbersome. At the same time, 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 respectively, 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, which will cause 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 method for installing a cutting tool and a workpiece, wherein the mounting plate and the workpiece are detachably connected, and the mounting plate is not damaged when it is installed or removed; the bearing seat is fixed during installation, and the bearing seat is stably installed on the mounting plate.

[0005] To achieve the above objectives, the technical solution of the present invention is: a method for installing a cutting tool and a processing device, comprising the following steps:

[0006] S1. Weld threaded columns onto the equipment to be processed, then fit the mounting plate onto the threaded columns through the fixing holes and fix the mounting plate in position with nuts.

[0007] S2. Insert the bearing housing through the hole in the mounting plate.

[0008] S3. Install the positioning bolt in the positioning threaded hole.

[0009] S4. Determine the position of the hole to be bored.

[0010] S5. Adjust the positioning bolts and move the bearing housing. 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.

[0011] S6. Install the locking assembly in the mounting hole of the bearing housing and the connection hole of the mounting plate; the locking assembly fixes the clamping part of the bearing housing to the mounting plate.

[0012] The above method first fixes the mounting plate to the equipment to be processed. The mounting plate is then installed on the equipment using fixing holes, bolts, and nuts, creating a detachable connection that prevents damage during installation and removal. Next, the through-hole and clamping parts are fitted together, and the bearing housing is connected to the mounting plate. Then, positioning bolts are installed and the bearing housing position is adjusted. The length of the three positioning bolts extending into the through-hole is adjusted to allow the bearing housing to move radially within the through-hole. This method is simple. Once the bearing's axis in the bearing housing is aligned with the boring hole, the positioning bolts provide the first fixation. Finally, a locking assembly is installed on the clamping part between the mounting plate and the bearing housing, providing a second fixation.

[0013] Meanwhile, the positioning component is set along the radial direction of the through hole, and the positioning component fixes the bearing housing along the radial direction of the bearing housing. The locking component is set along the axial direction of the through hole, and the locking component 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.

[0014] 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.

[0015] Furthermore, this is achieved through a bearing adjustment structure, which includes a mounting plate and a bearing housing. A bearing is housed in the bearing housing. The mounting plate has two or more fixing parts with fixing holes. The mounting plate has through holes along its thickness direction, and two or more movably positioned positioning components are located on the mounting plate along the radial direction of the through holes. One end of each positioning component extends into the through hole. A clamping part is located at one end of the bearing housing, and a through-hole is located at one end of the clamping part. The clamping part abuts against the mounting plate, and the through-hole passes through the through hole. The positioning components contact the through-hole and position the bearing housing. The positioning components include a positioning threaded hole and a positioning bolt. The positioning threaded hole is located on the mounting plate along the radial direction of the through hole, and the positioning bolt is located in the positioning threaded hole, with one end extending into the through hole.

[0016] The above configuration, through the connection of the through-hole and the through-part, connects the bearing housing to the mounting plate. Simultaneously, the clamping part abuts against the mounting plate, ensuring a good fit between the bearing housing and the mounting plate. The positioning component and the locking component work together to fix the bearing housing, providing good stability. The positioning component is positioned radially along the through-hole, fixing the bearing housing in the radial direction. The locking component is positioned axially along the through-hole, fixing the bearing housing in the axial direction. This design restricts both axial and radial movement of the bearing housing, preventing displacement when it is used with the tool drive shaft.

[0017] Meanwhile, the positioning component is movable on the mounting plate. By adjusting the length of the end of the positioning component extending into the through hole, the position of the bearing housing on the mounting plate can be adjusted, thus achieving coaxial positioning of the bearing housing and the boring hole to be machined.

[0018] Furthermore, the connecting hole is a waist hole.

[0019] Furthermore, after S6, it also includes:

[0020] S7. If the bearing housing position needs to be changed, proceed to S8.

[0021] S8. The locking assembly releases the connection between the clamping part and the mounting plate.

[0022] S9. Adjust the positioning bolts, move the bearing housing again, and move the locking assembly in the connecting hole; after the bearing housing has been moved, proceed to S10.

[0023] S10, the positioning bolts fix the position of the bearing housing; the locking assembly locks the clamping part to the mounting plate.

[0024] The above method involves first releasing the locking assembly from the bearing housing and mounting plate, then adjusting the positioning assembly to change the position of the bearing housing, and finally locking the bearing housing and mounting plate again with the locking assembly. 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.

[0025] Furthermore, the locking assembly includes a locking nut and a locking bolt, with the locking bolt passing through a mounting hole and a connection hole to connect with the locking nut.

[0026] The above setup uses a threaded connection between a locking bolt and a locking nut to press the clamping part onto the mounting plate, and the clamping part is fixed by the friction between the clamping part and the mounting plate.

[0027] Furthermore, S8 specifically involves releasing the locking nut from the locking bolt, thus separating the clamping part from the mounting plate. This operation is simple.

[0028] Furthermore, S10 specifically involves tightening the locking nut to lock the locking bolt, and the locking assembly pressing the clamping part against the mounting plate. This simplifies the operation.

[0029] Furthermore, the fixing holes are oblong holes. This facilitates the adjustment of the mounting plate's position at the processing location, and by movably setting the mounting plate and bearing housing, the range of motion of the bearing housing is increased. Attached Figure Description

[0033] Figure 4 This is a flowchart of the present invention. Detailed Implementation

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1-4As shown, a method for installing a cutting tool and a workpiece is achieved through a bearing adjustment structure. The bearing adjustment structure includes a mounting plate 1 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 through hole 11 along its thickness direction. Two or more movable positioning components 3 are provided on the mounting plate 1 along the radial direction of the through hole 11. One end of the positioning component 3 extends into the through hole 11. A pressing part 21 is provided at one end of the bearing housing 2, and a through part 22 is provided at one end of the pressing part 21. The pressing part 21 abuts against the mounting plate 1, and the through part 22 passes through the through hole 11. The bearing housing 2 and the mounting plate 1 are connected through the cooperation of the through part 22 and the through hole 11. At the same time, the pressing part 21 abuts against the mounting plate 1, so that the fit between the bearing housing 2 and the mounting plate 1 is good.

[0036] The positioning component 3 contacts the through-hole 22 and positions the bearing seat 2. A locking component 4 is connected to the clamping part 21 and the mounting plate 1 along the axial direction of the through-hole 11. The positioning component 3 and the locking component 4 work together to fix the bearing seat 2, resulting in good stability. The positioning component 3 is set along the radial direction of the through-hole 11 and fixes the bearing seat 2 in the radial direction. The locking component 4 is set along the axial direction of the through-hole 11 and fixes the bearing seat 2 in the axial direction. This restricts the movement of the bearing seat 2 in both the axial and radial directions, so that the bearing seat 2 is less likely to shift when used with the tool drive shaft.

[0037] 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 through hole 11, the position of the bearing seat 2 on the mounting plate 1 is adjusted; so that the bearing of the bearing seat 2 and the boring hole to be processed are coaxially set; in use, first release the locking component 4 from locking the bearing seat 2 and the mounting plate 1, then adjust the positioning component 3 to change the position of the bearing seat 2, and then lock the bearing seat 2 and the mounting plate 1 again with the locking component 4.

[0038] The mounting plate 1 has two or more connecting holes 12 surrounding the through hole 11, and the clamping part 21 has two or more mounting holes 23 surrounding the through part 22. In this embodiment, both the connecting holes and the mounting holes are three. The mounting holes 23 and the connecting holes 12 are connected by a locking assembly 4. The clamping part 21 is connected to the mounting plate 1 by the cooperation of the mounting holes 23 and the connecting holes 12, which is a simple structure.

[0039] In this embodiment, the connecting hole 12 is a slotted hole. By setting the connecting hole 12 as a slotted hole, the locking component 4 can move within the connecting hole 12 after being released. This allows the bearing seat 2 to move without completely disassembling the locking component 4, making it convenient to use.

[0040] The locking assembly 4 includes a locking nut and a locking bolt. The locking bolt passes through the mounting hole 23 and the connecting hole 12 and is connected to the locking nut. The threaded connection between the locking bolt and the locking nut allows 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.

[0041] 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 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 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 through hole 11 can be changed, facilitating the adjustment of the position of the bearing seat 2.

[0042] 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 are oblong 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 bearing seat 2, the range of motion of the bearing seat 2 is increased.

[0043] The bearing installation method includes the following steps:

[0044] S1. Weld threaded columns onto the equipment to be processed, then fit the mounting plate onto the threaded columns through the fixing holes and fix the mounting plate in position with nuts.

[0045] S2. Insert the bearing housing through the hole in the mounting plate.

[0046] S3. Install the positioning bolt in the positioning threaded hole.

[0047] S4. Determine the position of the hole to be bored.

[0048] S5. Adjust the positioning bolts and move the bearing housing. 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.

[0049] S6. Install the locking assembly in the mounting hole of the bearing housing and the connection hole of the mounting plate; the locking assembly fixes the clamping part of the bearing housing to the mounting plate.

[0050] S7. If the bearing housing position needs to be changed, proceed to S8.

[0051] S8. The locking assembly releases the connection between the clamping part and the mounting plate. By releasing the locking nut from the locking bolt, the clamping part separates from the mounting plate.

[0052] S9. Adjust the positioning bolts, move the bearing housing again, and move the locking assembly in the connecting hole; after the bearing housing has been moved, proceed to S10.

[0053] S10. The positioning bolts fix the position of the bearing housing; the locking assembly locks the clamping part to the mounting plate. By locking the locking bolts with the lock nut, the locking assembly presses the clamping part against the mounting plate.

[0054] The above method first fixes the mounting plate, enabling its installation on the equipment to be processed. The detachable connection between the mounting plate and the equipment prevents damage to the mounting plate during installation and removal. Then, the through-hole mates with the through-hole, and the clamping part abuts against the mounting plate, connecting the bearing housing to the mounting plate. Next, positioning bolts are installed, and the position of the bearing housing is adjusted. By adjusting the length of the three positioning bolts extending into the through-hole, the bearing housing can move radially within the through-hole. This method is simple. Once the bearing housing's axis is aligned with the boring hole, the positioning bolts provide the first fixation. Finally, a locking assembly is installed on the clamping part between the mounting plate and the bearing housing, providing a second fixation.

[0055] If the bearing housing position needs to be changed a second time, first release the locking assembly from locking the bearing housing and mounting plate, then adjust the positioning assembly to change the bearing housing position, and then lock the bearing housing and mounting plate again with the locking assembly. 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.

[0056] 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.
