[0020] In order to describe the technical content and structural features of the present application in detail, the following further description is made in combination with the embodiments and the accompanying drawings.
[0021] Referring to Fig. 1, Figures 1 to 3 the automatic tool telescopic device 100 of the present application comprises a shank 10, a rotary driver 20, a rotary shaft 30 and a sliding telescopic body 40 for embedding a tool 200. The rotary shaft 30 is rotatably arranged at the shank 10 to meet the need that the rotary shaft 30 can rotate relative to the shank 10; alternatively, Figures 1 to 3 as an example, the rotary shaft 30 is built in the shank 10 to meet the need that the rotary shaft 30 is hidden in the shank 10; in addition, the rotary shaft 30 is a straight shaft body, but it is not limited thereto.
[0022] The rotating driver 20 is configured to drive the rotating shaft 30 to rotate and provide power for the rotation of the rotating shaft 30. Figures 1 to 3 For example, the rotating driver 20 is a rotating motor. Obviously, according to actual needs, the rotating driver 20 can also be a rotating cylinder or a rotating hydraulic cylinder, which is not limited in this way.
[0023] The sliding telescopic body 40 can slide on the shank 10 in a direction intersecting the axial direction of the rotating shaft 30 (indicated by double-headed arrow A) to meet the needs of the sliding telescopic body 40 relative to the shank 10. Figures 1 to 3 For example, the sliding direction of the sliding telescopic body 40 (indicated by double-headed arrow B) is perpendicular to the axial direction of the rotating shaft 30. Obviously, according to actual needs, the relationship between the sliding direction of the sliding telescopic body 40 and the axial direction of the rotating shaft 30 can also be other, which is not limited in this way. Figures 1 to 3
[0024] Meanwhile, the sliding telescopic body 40 is also arranged in connection with the rotating shaft 30. Therefore, in the process of the rotating shaft 30 being driven to rotate by the rotating driver 20, the sliding telescopic body 40 is connected with the rotating shaft 30 to slide relative to the shank 10, so that in the process of the tool 200 on the sliding telescopic body 40 entering the product from the inner opening of the product, the tool 200 is retracted relative to the shank 10 by the sliding telescopic body 40, so as to facilitate the shank 10, the sliding telescopic body 40 and the tool 200 to enter the product. After the tool 200 enters the product, the tool 200 is extended relative to the shank 10 by the sliding telescopic body 40 to meet the needs of the tool 200 processing the inside of the product. More specifically, as follows:
[0025] As shown in Figures 1 to 3 For example, the rotating driver 20 is arranged side by side with the first end 11 of the shank 10. This design can avoid the size increase of the rotating driver 20 and the shank 10 in the series direction due to the series arrangement. Figures 1 to 3 For example, the rotating driver 20 is arranged side by side with the first end 11 of the shank 10 in the sliding direction of the sliding telescopic body 40 (indicated by double-headed arrow B). This design can avoid the side-by-side direction of the rotating driver 20 and the first end 11 of the shank 10 occupying more space due to the inconsistency with the sliding direction of the sliding telescopic body 40, so that the structure of the tool automatic telescopic device 100 is more compact.
[0026] As shown in Figures 1 to 3 , the output end 21 of the rotating driver 20 is equipped with a driving gear 22, and the rotating shaft 30 is equipped with a driven gear 31 which is in transmission with the driving gear 22, so that the rotating driver 20 can precisely drive the rotating shaft 30 through the cooperation of the driving gear 22 and the driven gear 31. Figures 1 to 3 Specifically, as an example, the diameter of the driving gear 22 is smaller than that of the driven gear 31, so that the rotating driver 20 can be designed to reduce the speed and increase the torque.
[0027] As shown in FIG. Figures 1 to 3 As an example, the sliding telescopic body 40 is slidably arranged in the second end 13 of the tool shank 10, so that the rotating driver 20 and the sliding telescopic body 40 are arranged at different ends of the tool shank 10, that is, the rotating driver 20 is arranged at the first end 11 of the tool shank 10, and the sliding telescopic body 40 is arranged at the second end 13 of the tool shank 10. In addition, the end of the rotating shaft 30 is provided with a connecting gear 32, and the sliding telescopic body 40 is correspondingly provided with a connecting rack 41 which is in mesh with the connecting gear 32, so that the sliding telescopic body 40 can be driven to slide and telescope by the rotating shaft 30 through the cooperation of the connecting gear 32 and the connecting rack 41. In addition, the end of the sliding telescopic body 40 is provided with an embedded installation cavity 42 for embedding and installing the tool 200, and the cavity opening 421 of the embedded installation cavity 42 is arranged upward, so as to facilitate the embedding and installing operation of the tool 200 on the sliding telescopic body 40 from above.
[0028] The working principle of the tool automatic telescopic device is described as follows: in use, the first end 11 of the tool shank 10 is connected with the tool feeding mechanism, and the tool feeding mechanism controls the tool automatic telescopic device 100 to feed.
[0029] During the process of the tool automatic telescopic device 100 entering the product from the inner opening of the product, the rotating driver 20 drives the rotating shaft 30 to rotate through the driving gear 22 and the driven gear 31, and the rotating shaft 30 drives the sliding telescopic body 40 and the tool 200 to retract relative to the tool shank 10 through the cooperation of the connecting gear 32 and the connecting rack 41. Figure 1the position shown; at this time, under the drive of the feed mechanism, the cutter automatic telescopic device 100 of the utility model enters the product; then, the rotating driver 20 drives the rotating shaft 30 to rotate in the opposite direction through the driving gear 22 and the driven gear 31, and the rotating shaft 30 drives the sliding telescopic body 40 together with the cutter 200 to extend relative to the cutter handle 10 to the position shown through the cooperation of the connecting gear 32 and the connecting rack 41, so as to meet the need that the cutter automatic telescopic device 100 of the utility model realizes the machining of the inside of the product under the control of the feed mechanism. Figure 2 The cutter automatic telescopic device 100 of the utility model realizes the machining of the inside of the product under the control of the feed mechanism.
[0030] Compared with the prior art, the cooperation of the rotating shaft 30, the rotating driver 20 and the sliding telescopic body 40 makes the rotating shaft 30 drive the sliding telescopic body 40 and the cutter 200 on the sliding telescopic body 40 to extend and retract relative to the cutter handle 10 under the drive of the rotating driver 20, so that the cutter 200 is not limited by the size of the inner opening of the product, and the cutter 200 can machine different structures inside the product and can machine relatively deep positions inside the product, and further allows the structure design of the product to be relatively complex.
[0031] The above only discloses the preferred examples of the utility model, and cannot limit the scope of the utility model, so equivalent changes made according to the utility model claims all belong to the scope covered by the utility model.
