[0005] Therefore, the technical solution adopted by this utility model is as follows: a deep groove turning tool for internal holes, comprising: a main body mechanism, the main body mechanism including a tool holder, an extension plate symmetrically fixed at the end of the tool holder, a rotating seat rotatably installed between the relative extension plates, a tool head fitted on the rotating seat, a bolt passing through the tool head and meshing with the tool seat, a transmission component symmetrically installed in the inner cavity of the tool holder and extending into the extension plate and meshing with the rotating seat, a driving component installed in the inner cavity of the tool holder and meshing with the transmission component, and an angle sensor disposed in the inner cavity of the tool holder and connected at its end to the driving component.
[0006] In a preferred embodiment, the present invention can be further configured such that the rotating seat includes a support rotatably mounted between opposite extension plates and having its end extending into the inner cavity of the extension plates, a first bevel gear symmetrically fixed on both sides of the support, and a tool holder integrally fixed on one side of the support.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0022] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example 1
[0023] Combination Figure 1-4 As shown, this embodiment provides an internal deep groove turning tool, including: a main body mechanism 100.
[0024] The main body 100 includes a tool bar 110, an extension plate 120 symmetrically fixed to the end of the tool bar 110, a rotating seat 130 rotatably mounted between the relative extension plates 120, a tool head 140 fitted on the rotating seat 130, a bolt 150 passing through the tool head 140 and meshing with the tool holder 133, a transmission component 160 symmetrically mounted in the inner cavity of the tool bar 110 and extending into the extension plate 120 and meshing with the rotating seat 130, a drive component 170 mounted in the inner cavity of the tool bar 110 and meshing with the transmission component 160, and an angle sensor 180 disposed in the inner cavity of the tool bar 110 and connected at its end to the drive component 170.
[0025] The tool holder 110 is used to be fixedly connected to the drive mechanism of the lathe. The extension plate 120 is integrally fixed to the end of the tool holder 110 and is used to install the rotating seat 130 to ensure the stability of the rotating seat 130.
[0026] The rotating base 130 is used to install the cutting head 140. It includes a support 131 that is rotatably installed between the relative extension plates 120 and whose end extends into the inner cavity of the extension plate 120, a first bevel gear 132 that is symmetrically fixed on both sides of the support 131, and a tool holder 133 that is integrally fixed on one side of the support 131. A positioning groove 1331 is opened at the end of the tool holder 133. The cutting head 140 is fitted into the positioning groove 1331 to ensure the stability of the cutting head 140 during turning. At the same time, a threaded hole is opened on the inner bottom wall of the positioning groove 1331. A bolt 150 passes through the cutting head 140 and engages in the threaded hole to fix the cutting head 140 and the tool holder 133 together.
[0027] The transmission component 160 is used for transmission and includes a round rod 161 rotatably disposed in the inner cavity of the tool holder 110, a second bevel gear 162 fixed at one end of the round rod 161, and a third bevel gear 163 fixed at the other end of the round rod 161. The second bevel gear 162 meshes with the first bevel gear 132. Meanwhile, the drive component 170 includes a micro motor 171 mounted in the inner cavity of the tool holder 110 and a fourth bevel gear 172 fixed on the shaft of the micro motor 171. The fourth bevel gear 172 meshes with the third bevel gear 163. When the micro motor 171 starts, it drives the fourth bevel gear 172 to rotate. The rotation of the fourth bevel gear 172 drives the third bevel gear 163 to rotate. The rotation of the third bevel gear 163 drives the second bevel gear 162 to rotate through the round rod 161. The rotation of the second bevel gear 162 drives the first bevel gear 132 to rotate. The rotation of the first bevel gear 132 drives the support 131 to rotate, that is, drives the tool holder 133 to rotate, thereby adjusting the angle of the tool head 140.
[0028] In addition, the end of the angle sensor 180 is fixedly connected to the middle of the fourth bevel gear 172, which facilitates real-time monitoring of the rotation angle of the fourth bevel gear 172. At the same time, the diameter and number of teeth of the fourth bevel gear 172 and the first bevel gear 132 are equal. Therefore, when the rotation angle of the fourth bevel gear 172 is equal to the rotation angle of the first bevel gear 132, it is convenient for the angle sensor 180 to monitor it.
[0029] The working principle and usage process of this utility model are as follows: When it is necessary to process a deep groove with an inclined inner hole, the micro motor 171 is started, driving the fourth bevel gear 172 to rotate. The rotation of the fourth bevel gear 172 drives the third bevel gear 163 to rotate. The rotation of the third bevel gear 163 drives the second bevel gear 162 to rotate through the round rod 161. The rotation of the second bevel gear 162 drives the first bevel gear 132 to rotate. The rotation of the first bevel gear 132 drives the support 131 to rotate, which in turn drives the tool holder 133 to rotate, adjusting the angle of the tool head 140. Since the diameter and number of teeth of the first bevel gear 132 and the fourth bevel gear 172 are equal, the rotation angle of the fourth bevel gear 172 is equal to the rotation angle of the first bevel gear 132. At this time, the angle sensor 180 detects the rotation angle of the fourth bevel gear 172. When the fourth bevel gear 172 rotates to the specified angle, the micro motor 171 is turned off, completing the adjustment of the angle of the tool head 140.
[0030] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
