Description

Technical Field

[0001] This application relates to the technical field of drilling for parts, and in particular to a drilling apparatus for machining lightweight rotor disks for land use. Background Technology

[0002] Currently, such as Figure 1 The lightweight rotor disc 100 for land use in the wind turbine shown has several connecting holes 101 and through holes 102 evenly opened on its surface. The diameter of the through holes is small, but the number is large. During production and processing, the connecting holes and through holes are generally processed in two drilling machines respectively. This processing method requires two loading and unloading processes, as well as storage and transportation. The whole process is relatively complicated and the production efficiency is low.

[0003] Therefore, in order to improve production efficiency, it is urgent to develop new drilling equipment. Utility Model Content

[0004] The purpose of this application is to provide a drilling apparatus for machining lightweight rotor disks on land, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides a drilling device for machining lightweight rotor disks on land, employing the following technical solution:

[0006] A drilling device for machining lightweight rotor disks on land includes a housing, in which a coarse shaft drilling machine and a fine shaft drilling machine are respectively installed. The housing also includes a loading and unloading mechanism, comprising a hydraulic cylinder, a lifting platform, a first cam divider, a turntable, and a clamping assembly mounted on the turntable. A second cam divider and a third cam divider are respectively positioned within the housing corresponding to the positions of the coarse and fine shaft drilling machines. A turntable is mounted on the output shaft of each of the second and third cam dividers. An electromagnet is fixed in the center of the turntable. The hydraulic cylinder is vertically fixed within the housing. The lifting platform is located on top of the hydraulic cylinder. The first cam divider is fixed on the lifting platform. The turntable is fixed on the output shaft of the first cam divider. Four mounting slots are evenly distributed on the turntable, and the clamping assembly is disposed within each mounting slot.

[0007] The clamping assembly includes a slewing bearing, a base, and multiple quick clamps. The slewing bearing is fixed in the mounting groove, the base is mounted on the slewing bearing, the multiple quick clamps are fixed on the base, and an armature is fixed at the bottom of the base corresponding to the position of the electromagnet.

[0008] The base has an annular support at the top, and a clearance groove is provided in the middle of the annular support. Waste discharge ports that penetrate the clearance groove are provided on both the inner and outer walls of the annular support. A limiting block adapted to the land-based lightweight rotor disk is also provided on the annular support. The number of quick clamps is three, and the three quick clamps are respectively located next to the limiting block.

[0009] Preferably, the upper surface of the slewing bearing is higher than the table surface of the turntable, and a brush is installed on the base.

[0010] By adopting the above technical solution, the base drives the brush to rotate along the circumference of the slewing bearing, which can prevent the accumulation of waste and eliminate the need for manual cleaning. The structural design is relatively reasonable.

[0011] A waste discharge trough is connected to the bottom side of the casing.

[0012] The first cam divider, the second cam divider, and the third cam divider are each matched with a motor.

[0013] In summary, this application includes at least one of the following beneficial technical effects: the drilling device for processing lightweight rotor disks on land integrates a coarse shaft drilling machine and a fine shaft drilling machine, and is equipped with a second cam divider and a third cam divider. The second cam divider and the third cam divider are equipped with dividers at different positions according to the number of holes to be drilled, which can accurately and completely complete the drilling work. The first cam divider realizes the switching of drilling positions. The operator only needs to load and unload materials, which greatly improves the production efficiency.

[0019] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0020] This application discloses a drilling apparatus for machining lightweight rotor disks on land, with reference to... Figure 2-4 The system includes a housing 1, with a waste discharge trough connected to the bottom side of the housing 1. A coarse shaft drilling machine 2 and a fine shaft drilling machine 3 are installed inside the housing 1. A loading / unloading mechanism 4 is also provided inside the housing 1. The loading / unloading mechanism 4 includes a hydraulic cylinder 41, a lifting platform 42, a first cam divider 43, a turntable 44, and a clamping assembly 5 mounted on the turntable 44. A second cam divider 6 and a third cam divider 7 are respectively installed inside the housing 1 at positions corresponding to the coarse shaft drilling machine 2 and the fine shaft drilling machine 3. Rotary screws are mounted on the output shafts of both the second cam divider 6 and the third cam divider 7. A turntable 8 is provided, with an electromagnet 9 fixed in the middle. To facilitate the energization of the electromagnet 9, a conductive slip ring is also installed on the turntable 8. A hydraulic cylinder 41 is vertically fixed inside the housing 1. A lifting platform 42 is set on top of the hydraulic cylinder 41. A first cam divider 43 is fixed on the lifting platform 42. A turntable 44 is fixed on the output shaft of the first cam divider 43. Four mounting slots are evenly provided on the turntable 44. A clamping assembly 5 is set in the mounting slots. The first cam divider 43, the second cam divider 6, and the third cam divider 7 are respectively matched and connected to motors.

[0021] The clamping assembly 5 includes a slewing bearing 51, a base 52, and multiple quick clamps 53. The slewing bearing 51 is fixed in the mounting groove, the base 52 is mounted on the slewing bearing 51, and the multiple quick clamps 53 are fixed on the base 52. An armature is fixed at the bottom of the base 52 corresponding to the position of the electromagnet 9.

[0022] Reference Figure 4The base 52 has an annular support 521 at the top, and a relief groove 522 is provided in the middle of the annular support 521. In order to facilitate the discharge of waste chips and cutting fluid, waste discharge ports 523 that penetrate the relief groove 522 are provided on both the inner and outer walls of the annular support 521. A limiting block 524 adapted to the land-based lightweight rotor disk is also provided on the annular support 521. Three quick clamps 53 are provided, and the three quick clamps 53 are respectively located next to the limiting block 524. The upper surface of the slewing bearing 51 is set higher than the table surface of the turntable 44, and a brush 525 is installed on the base 52. By providing the brush 525, the waste chips around the slewing bearing 51 can be scraped away during the rotation of the base 52 to avoid accumulation.

[0023] The implementation principle of a drilling device for machining lightweight rotor disks on land according to an embodiment of this application is as follows:

[0024] The operator places the land-based lightweight rotor disc onto the annular support 521, and then uses three quick clamps 53 to press the land-based lightweight rotor disc onto the base 52. The hydraulic cylinder 41 drives the lifting platform 42 to rise, and the first cam divider 43 drives the turntable 44 to rotate once, so that the clamping assembly 5 moves to the bottom of the coarse shaft drilling machine 2. The hydraulic cylinder 41 returns to its original position, and the base 52 stops on the electromagnet 9 at the top of the second cam divider 6. At this time, the electromagnet 9 is energized, which can attract and fix the base 52. After that, the second cam divider 6 drives the base 52 to rotate (each rotation is a drilling position). With the help of the coarse shaft drilling machine 2, the connecting holes can be processed evenly. Similarly, in this process, the previous lightweight rotor disc is located at the bottom of the fine shaft drilling machine 3 and is driven to rotate by the third cam divider 7. With the help of the fine shaft drilling machine 3, the through holes can be processed. The operator only needs to load and unload the material. The processing of connecting holes and through holes can be achieved in one clamping, which greatly improves production efficiency.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
