Description

Technical Field

[0001] The invention relates to an integrated cutting and grinding device, in particular to an integrated cutting and grinding device for pre-embedded bolts of wind turbine blades applied in the field of bolt processing. Background Art

[0002] The bolts at the connection position of the existing wind turbine blades are generally easy to deviate and difficult to assemble. Without auxiliary devices, once the bolts are offset in the parallel direction, the connection of the wind turbine blades will not be tight, thus affecting the service life of the wind turbine blades, which is difficult to meet social needs. Therefore, when processing bolts, continuous grinding and cutting are required to ensure processing accuracy. When processing embedded bolts for wind turbine blades, cutting and grinding are often performed separately, which is inefficient and generates waste. If not cleaned up in time, it is easy to pollute the environment.

[0003] In order to improve the above problems, after searching, for example, the specification of the patent publication number CN112571063B discloses an integrated tool for cutting and grinding pre-embedded bolts of wind turbine blades, including a main body mechanism and a power mechanism, a placement groove is arranged on the main body mechanism, and the bolts to be processed are placed; the chip removal grooves are arranged on the main body mechanism along both sides of the placement groove; the dust suction holes are opened on one side of the main body mechanism; the grinding mechanism is arranged in the placement groove; the bolts to be processed are placed in the placement groove, and the waste edges of the bolts to be processed are first cut along the chip removal groove by an external cutting mechanism, and the waste is discharged from the chip removal groove into the receiving groove, and then sucked out from the dust suction hole by the external first dust suction mechanism; finally, the power mechanism is started, so that the grinding mechanism grinds the bolts to be processed, thereby improving the processing efficiency.

[0004] Based on the above search and in combination with the prior art, it is found that most of the existing bolt cutting and grinding devices cut and grind the bolt blanks by reciprocating motion, and are convenient for replacing the bolt blanks before and after cutting and grinding. However, the existing bolt cutting and grinding devices generally need to slow down or even stop during operation to replace the bolt blanks, and frequent acceleration and deceleration or start and stop undoubtedly increase the energy consumption of the operation, and shorten the service life of the driving equipment to a certain extent. Therefore, a wind turbine blade embedded bolt cutting and grinding integrated device is proposed to improve the above problems. Summary of the invention

During this process, the cutting mechanism and the grinding mechanism cut and grind the bolt blank respectively; The second stage: the telescopic arm moves quickly with the mounting base under the action of the speed change gear set. During this process, the mounting base brings the cutting mechanism and the grinding mechanism back to the initial working position.

[0007] In the above-mentioned integrated device for cutting and grinding pre-embedded bolts for wind turbine blades, the driving motor can be kept in a uniform speed driving state through the coordinated setting of the circulating track and the speed change gear group, so that the mounting seat can rotate one circle along the circulating track with the cutting mechanism and the grinding mechanism, and in the process of the cutting mechanism and the grinding mechanism passing through the working path, the speed change gear group drives the mounting seat to move slowly to ensure stable cutting and grinding; in the process of the cutting mechanism and the grinding mechanism passing through the non-working path, the speed change gear group drives the mounting seat to move quickly, which facilitates the replacement of the bolt blank and shortens the replacement time of the bolt blank, thereby improving the working efficiency.

[0013] As a further supplement to the present application, in the process that the driving motor drives the first driving gear to rotate with the first driven gear, the transmission shaft moves slowly along one section of the linear slide groove on the circulating track with the mounting seat through the telescopic arm; When the driving motor drives the second driving gear to rotate with the second driven gear, the transmission shaft moves quickly to the initial operation position along the remaining part of the circulating track with the mounting seat through the telescopic arm.

[0014] As a further supplement to the present application, a cooling pipe group is installed at the upper end of the mounting seat, and the cooling pipe group includes a hard pipe and an elastic pipe.

[0021] Furthermore, a linear slide groove 201 and a curved slide groove 202 are correspondingly arranged on the circulating track 2, and the limit slider 8 is slidingly fitted with the linear slide groove 201. The size of the curved slide groove 202 is larger than that of the linear slide groove 201, and the limit slider 8 will not separate from the curved slide groove 202. A variable diameter slide groove is arranged between the linear slide groove 201 and the curved slide groove 202 to provide a stable transition for the limit slider 8.

[0022] A cutting mechanism 4 and a grinding mechanism 5 are installed side by side at the upper end of the mounting seat 3. The cutting mechanism 4 is located on one side of the grinding mechanism 5 close to the moving direction of the mounting seat 3. The driving mechanism 6 is installed in the middle of the machine base 1. The driving mechanism 6 includes a driving motor 61, a speed gear set and a telescopic arm 67. The driving motor 61 is installed on the machine base 1. The telescopic arm 67 is arranged horizontally. One end of the telescopic arm 67 is connected to the output shaft of the driving motor 61 through the speed gear set, and the other end of the telescopic arm 67 is rotatably connected to the mounting seat 3, so that in the process of the driving motor 61 driving one circle, the telescopic arm 67 is driven by the speed gear set to move the mounting seat 3 around the circulating track 2. This process includes two stages: The first stage: the telescopic arm 67 moves slowly with the mounting seat 3 under the action of the speed change gear set. During this process, the cutting mechanism 4 and the grinding mechanism 5 cut and grind the bolt blank respectively. The second stage: the telescopic arm 67 moves quickly with the mounting base 3 under the action of the speed change gear set. During this process, the mounting base 3 returns to the initial operation position with the cutting mechanism 4 and the grinding mechanism 5.

The above-mentioned linear processing method is a conventional processing operation in the prior art, such as the link: Video content in https: / / v.youku.com / v_show / id_XNjQyMjQ4MjIwMA==.html.

[0024] The integrated device for cutting and grinding embedded bolts for wind turbine blades can keep the drive motor 61 in a uniform speed driving state through the coordinated setting of the circulating track 2 and the speed gear set, so that the mounting seat 3 rotates one circle along the circulating track 2 with the cutting mechanism 4 and the grinding mechanism 5, and when the cutting mechanism 4 and the grinding mechanism 5 pass through the working path, the speed gear set drives the mounting seat 3 to move slowly to ensure stable cutting and grinding; when the cutting mechanism 4 and the grinding mechanism 5 pass through the non-working path, the speed gear set drives the mounting seat 3 to move quickly, which facilitates the replacement of the bolt blank and shortens the replacement time of the bolt blank, thereby improving the working efficiency.

[0025] Regarding the speed gear set, specifically, the speed gear set includes a transmission shaft 64, a first speed group and a second speed group. The transmission shaft 64 is vertically rotatably mounted on the machine base 1, the telescopic arm 67 is fixed to the top of the transmission shaft 64, and the first speed group and the second speed group are both installed between the output shaft of the drive motor 61 and the transmission shaft 64.

[0026] Regarding the first gear change group, more specifically, the first gear change group includes a first driving gear 62 and a first driven gear 65. The first driving gear 62 is an incomplete gear. The first driving gear 62 is coaxially fixed to the output shaft of the drive motor 61, and the first driven gear 65 is coaxially fixed to the transmission shaft 64. The first driving gear 62 is meshed with the first driven gear 65, and the diameter of the first driving gear 62 is smaller than the diameter of the first driven gear 65.

[0027] Regarding the second gear change group, similarly, more specifically, the second gear change group includes a second driving gear 63 and a second driven gear 66, the second driving gear 63 is an incomplete gear, the second driving gear 63 is coaxially fixed to the output shaft of the drive motor 61, the second driven gear 66 is coaxially fixed to the transmission shaft 64, and the second driving gear 63 is meshed with the second driven gear 66, and the diameter of the second driving gear 63 is greater than the diameter of the second driven gear 66.

[0028] In the process that the driving motor 61 drives the first driving gear 62 to rotate with the first driven gear 65, the transmission shaft 64 moves slowly along one section of the linear slide groove 201 on the circulating track 2 with the mounting seat 3 through the telescopic arm 67; When the driving motor 61 drives the second driving gear 63 to rotate with the second driven gear 66 , the transmission shaft 64 moves quickly to the initial operation position along the remaining part of the circulating track 2 with the mounting seat 3 through the telescopic arm 67 .

The hard tube 71 is fixed to the external frame and connected to the external water tank. The elastic tube 72 is fixed to the mounting seat 3, and a rotating sealing connector 73 is installed between the hard tube 71 and the elastic tube 72.

[0030] Based on the coordinated arrangement of the above structure, during the operation, the cooling pipe group 7 can be used to spray water on the processing part of the bolt blank to reduce the temperature and dust. At the same time, the water flow can be used to take away the debris generated by cutting and grinding, thereby improving the grinding quality.

[0031] Working principle: During one rotation of the driving motor 61, the telescopic arm 67 is driven by the speed change gear set to move the mounting base 3 around the circulating track 2. This process includes two stages: The first stage: When the driving motor 61 drives the first driving gear 62 to rotate with the first driven gear 65, the transmission shaft 64 moves slowly along one section of the linear slide groove 201 on the circulating track 2 with the mounting seat 3 through the telescopic arm 67, as shown in FIG. Figure 8 As shown in the figure, n1 is the speed of the driving motor 61, n2 is the speed of the transmission shaft 64, and n1>n2. In this process, the cutting mechanism 4 and the grinding mechanism 5 cut and grind the bolt blank respectively; The second stage: during the process of the driving motor 61 driving the second driving gear 63 to rotate with the second driven gear 66, the transmission shaft 64 moves quickly to the initial operation position along the remaining part of the circulating track 2 with the mounting seat 3 through the telescopic arm 67, such as Fig. 9 As shown in the figure, n1 is the rotation speed of the driving motor 61, n3 is the rotation speed of the transmission shaft 64, and n3>n1. During this process, the mounting seat 3 brings the cutting mechanism 4 and the grinding mechanism 5 back to the initial working position.

[0032] Compared with the prior art, the present invention maintains the driving motor 61 in a uniform speed driving state through the coordinated setting of the circulating track 2 and the speed gear set, so that the mounting seat 3 rotates one circle along the circulating track 2 with the cutting mechanism 4 and the grinding mechanism 5, and when the cutting mechanism 4 and the grinding mechanism 5 pass through the working path, the speed gear set drives the mounting seat 3 to move slowly to ensure stable cutting and grinding; when the cutting mechanism 4 and the grinding mechanism 5 pass through the non-working path, the speed gear set drives the mounting seat 3 to move quickly, which facilitates the replacement of the bolt blank and shortens the replacement time of the bolt blank, thereby improving the working efficiency.

[0033] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
