Description

Technical Field

[0001] The invention relates to a surfacing method, in particular to a method for connecting an abrasive belt polisher and a lathe tool holder, and belongs to the technical field of abrasive belt polisher connection. Background Art

[0002] As my country's large-scale manufacturing industry becomes increasingly mature, the technology of the steam turbine manufacturing industry is also booming. The structure of steam turbine rotors is becoming increasingly complex, and the structure of steam turbine rotors is also more compact than before.

[0003] When a heavy-duty horizontal lathe is used to process the rotor, since the surface roughness of the rotor journal reaches Ra0.4, it is necessary to install a belt polisher on the lathe tool holder to polish the rotor journal.

[0004] like Figure 1 As shown, the current connection method between the belt polisher and the tool holder is mostly to connect the motor of the belt polisher directly to the tool holder, but due to the large width of the tool holder (generally more than 1 meter), this will cause the tool holder to easily interfere with the chuck, claws, tailstock or bracket of the lathe when using the belt polisher. This situation greatly limits the travel of the belt polisher, and there are local areas that cannot be polished for some compact rotors.

[0005] In summary, how to propose a new connection method to address the above technical issues has become an urgent problem to be solved by technicians in this field. Summary of the invention

[0006] In view of the above-mentioned deficiencies in the prior art, the present invention further provides a method for connecting a belt polisher and a lathe tool holder.

[0007] The technical solution of the present invention is: a method for connecting a belt polisher and a lathe tool holder, which is specifically carried out according to the following steps:

[0008] Step 1: Install the blade on the blade holder, and ensure that the blade is perpendicular to the axis of the rotor, the blade can be close to or away from the rotor, and the width of the blade is much smaller than the width of the blade holder;

[0009] Step 2: Install a tiger head blade row on the end face of the blade plate facing the rotor; the end face of the tiger head blade row facing the rotor is provided with a mounting groove, and threaded holes are processed on the tiger head blade row, and set screws are installed in the threaded holes;

[0010] Step 3, install the adapter on the tiger head blade row; the adapter includes an integrally arranged connecting plate and a connecting handle, the connecting plate and the connecting handle are arranged vertically, the connecting handle is inserted into the mounting groove of the tiger head blade row, and the set screw presses the connecting handle;

[0011] Step 4: Fix the motor of the belt polisher to the connecting plate of the adapter.

[0012] Compared with the prior art, the present invention has the following effects:

[0013] 1. The present invention adopts a knife plate 2, an adapter 3 and a tiger-head knife row 4 to provide a more applicable installation method for the belt polisher. When polishing the rotor, the position of the adapter 3 on the tiger-head knife row 4 and the position of the knife plate 2 on the tool holder 1 are adjusted, thereby avoiding interference between the belt polisher and components such as the lathe chuck 6, the claws 7, the tailstock or the bracket, and completing the polishing work of the rotor shaft diameter surface.

[0014] 2. The present invention has simple connection and convenient installation, and can be applied to the polishing work of the surface of the turbine rotor with a relatively compact structure. It improves the scope and flexibility of the use of the belt polisher on the heavy horizontal lathe, improves the versatility, and further improves the manufacturing efficiency and quality of the turbine rotor products.

[0021] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] Specific implementation method 1: Combination Figures 1 to 3 The present embodiment is described. A method for connecting a belt polisher to a lathe tool holder in the present embodiment is specifically performed according to the following steps:

[0023] Step 1: Install the blade 2 on the blade holder 1, and ensure that the blade 2 is perpendicular to the axis of the rotor, the blade 2 can be close to or away from the rotor, and the width of the blade 2 is much smaller than the width of the blade holder 1;

[0024] Step 2, install a tiger head cutter row 4 on the end surface of the cutter plate 2 facing the rotor; the end surface of the tiger head cutter row 4 facing the rotor is provided with a mounting groove, the length direction of the mounting groove is parallel to the axis of the rotor, and the tiger head cutter row 4 is processed with a threaded hole, and a set screw is installed in the threaded hole;

[0025] Step three, install the adapter 3 on the tiger head knife row 4; the adapter 3 includes an integrally arranged connecting plate and a connecting handle, the connecting plate and the connecting handle are arranged vertically, and the width of the connecting handle is less than the length of the mounting groove on the tiger head knife row 4, the connecting handle is inserted into the mounting groove of the tiger head knife row 4, and the set screw presses the connecting handle, so as to realize the adapter 3 being clamped on the tiger head knife row 4;

[0026] Step 4: Fix the motor of the belt polisher to the connecting plate of the adapter 3. After the connection is completed, the journal of the rotor can be polished.

[0027] Specific implementation method 2: Combination Figures 1 to 3 To illustrate this embodiment, in step 1 of this embodiment, a blade groove is opened on the blade holder 1, a threaded hole is processed on the blade holder 1, and a locking screw is installed in the threaded hole; the blade 2 is installed in the blade groove, and the locking screw presses the blade 2. With this arrangement, the blade 2 can adjust the extended length on the blade holder 1.

[0028] Furthermore, in step 2, the tiger-head blade row 4 is installed on the blade plate 2 by bolts.

[0029] Furthermore, in step three, a plurality of threaded holes are formed on the connecting plate of the adapter 3 .

[0030] Furthermore, in step 4, the motor bolts of the belt polisher are installed on the connecting plate of the adapter 3.

[0031] Other components and connection methods are the same as those in the first embodiment.

[0032] The present invention has been disclosed as above in the form of a preferred embodiment, but it is not intended to limit the present invention. Any simple modification, equivalent changes and modifications made to the above implementation cases by any professional and technical personnel who do not deviate from the content of the technical solution of the present invention and based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.

[0033] How it works

[0034] Combination Figures 1 to 5 The working principle of the present invention is described:

[0035] The blade plate 2 is mounted on the blade holder 1, a tiger head blade row 4 is mounted on the end surface of the blade plate 2 facing the rotor, and an adapter seat 3 is mounted on the tiger head blade row 4

[0036] When polishing the rotor, adjust the position of the adapter 3 on the tiger head cutter row 4 and the position of the cutter plate 2 on the tool holder 1 to avoid interference between the belt polisher and the lathe chuck 6, claws 7, tailstock or bracket and other components.

[0037] The width of the blade 2 is much smaller than the width of the tool holder 1. The belt polisher can be installed upright or inverted on the adapter 3 (that is, the motor of the belt polisher is facing toward or away from the lathe chuck 6), which greatly improves the stroke of the entire belt polisher along the length direction of the rotor, making the polishing work more flexible, thereby better completing the polishing work of the rotor shaft diameter surface.
