There are many types of power heads, which include drilling power heads depending on the machining method used.

[0003] Existing drilling power heads are inconvenient to guide during feed, making them prone to misalignment and consequently reducing drilling accuracy. This phenomenon has become a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision automatic feed drilling power head for existing devices, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-precision automatic feed drilling power head, including a support base, a drive motor and a cylinder body are fixedly connected to the outer wall of the support base, a cutter head mounting block is fixedly connected to the piston end of the cylinder body, a limit ring is movably connected to the outer wall of the cutter head mounting block, a connecting rod is fixedly connected to the outer wall of the limit ring, a slider is fixedly connected to one end of the connecting rod, a fixed guide rail is fixedly connected to the outer side of the support base near the cylinder body, a fixed block is fixedly connected to the inner wall of the fixed guide rail, a receiving groove is formed on the inner wall of the fixed block, and a rolling element is movably connected inside the receiving groove. By setting up a support base, drive motor, cylinder body, cutter head mounting block, limit ring, connecting rod, slider, fixed guide rail, fixed block, receiving groove and rolling element, the sliding guidance of the cutter head mounting block is facilitated while ensuring effective rotation of the cutter head mounting block, thereby improving the stability of the cutter head mounting block during feed, solving the problem of reduced drilling accuracy caused by misalignment, meeting people's work needs, and is worthy of promotion and use.

[0006] Furthermore, the outer wall of the cutter head mounting block is provided with an "I"-shaped fixing ring, which is rotatably connected to the limiting ring, facilitating the movement of the cutter head mounting block through the fixing ring to drive the limiting ring.

[0007] Furthermore, the connecting rod has an "L"-shaped structure, and the connecting rod is slidably connected to the fixed guide rail via a slider, which facilitates the movement of the slider driven by the limiting ring through the connecting rod.

[0008] Furthermore, the fixed guide rail has a U-shaped structure and is distributed at equal angles along the axial center line of the cutter head mounting block, which facilitates limiting and guiding through the fixed guide rail.

[0009] Furthermore, the diameter of the opening of the receiving groove is smaller than the diameter of the rolling element, and the rolling element is rotatably connected to the fixed block through the receiving groove, which prevents the rolling element from falling off and distributing.

[0010] Furthermore, the rolling elements are symmetrically distributed in two groups inside the fixed guide rail, and each group has several rolling elements at equal intervals. This facilitates the reduction of friction during slider sliding by using the rolling elements, thereby ensuring the guiding operation.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0012] (1) By setting up a support base, drive motor, cylinder body, cutter head mounting block, limit ring, connecting rod, slider, fixed guide rail, fixed block, receiving groove and rolling body, the cutter head mounting block can be slidably guided while ensuring effective rotation of the cutter head mounting block. This improves the stability of the cutter head mounting block during feeding, solves the problem of reduced drilling accuracy caused by misalignment, meets people's work needs, and is worth promoting and using.

Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a high-precision automatic feed drilling power head, including a support base 1. A drive motor 2 and a cylinder body 3 are fixedly connected to the outer wall of the support base 1. A tool head mounting block 4 is fixedly connected to the piston end of the cylinder body 3. A limit ring 5 is movably connected to the outer wall of the tool head mounting block 4. A connecting rod 6 is fixedly connected to the outer wall of the limit ring 5. A slider 7 is fixedly connected to one end of the connecting rod 6. A fixed guide rail 8 is fixedly connected to the outer side of the outer wall of the support base 1 near the cylinder body 3. A fixing block 9 is fixedly connected to the inner wall of the fixed guide rail 8. The inner wall of the fixing block 9 is open. The device includes a receiving groove 10, with a rolling element 11 movably connected inside. It is equipped with a support base 1, a drive motor 2, a cylinder body 3, a cutter head mounting block 4, a limit ring 5, a connecting rod 6, a slider 7, a fixed guide rail 8, a fixed block 9, the receiving groove 10, and the rolling element 11. This design facilitates the sliding guidance of the cutter head mounting block 4 while ensuring its effective rotation, thereby improving the stability of the cutter head mounting block 4 during feeding. It solves the problem of reduced drilling accuracy caused by misalignment, meets people's work needs, and is worthy of widespread use.

[0020] Furthermore, the outer wall of the cutter head mounting block 4 is provided with an "I"-shaped fixing ring, which is rotatably connected to the limiting ring 5, making it convenient for the cutter head mounting block 4 to drive the limiting ring 5 to move through the fixing ring.

[0021] Furthermore, the connecting rod 6 has an "L" shaped structure, and the connecting rod 6 is slidably connected to the fixed guide rail 8 through the slider 7, which facilitates the movement of the limit ring 5 through the connecting rod 6 to drive the slider 7.

[0022] Furthermore, the fixed guide rail 8 has a U-shaped structure and is distributed at equal angles along the axial center line of the cutter head mounting block 4, which facilitates limiting and guiding through the fixed guide rail 8.

[0023] Furthermore, the diameter of the opening of the receiving groove 10 is smaller than the diameter of the rolling element 11, and the rolling element 11 is rotatably connected to the fixed block 9 through the receiving groove 10, which prevents the rolling element 11 from falling off and distributing.

[0024] Furthermore, two sets of rolling elements 11 are symmetrically distributed inside the fixed guide rail 8, and each set of rolling elements 11 has several elements at equal intervals. This facilitates the reduction of friction on the sliding of the slider 7 through the rolling elements 11, thereby ensuring the guiding operation.

[0025] During use, when the cutter head mounting block 4 is feeding, it will drive the limiting ring 5 to move through the fixing ring on the outer wall. The limiting ring 5 will drive the connecting rod 6 to move, and the connecting rod 6 will drive the slider 7 to move. Thus, under the guidance of the fixed guide rail 8, the slider 7 will slide more stably, thereby improving the accuracy of the cutter head mounting block 4 driving the cutter head to perform drilling. In addition, when the slider 7 slides, it will drive the rolling element 11 to rotate. The rolling element 11 helps to reduce the friction of the slider 7, which in turn helps to extend its service life.
