PREFERRED EMBODIMENT

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] like Figs. 1-2 As shown, a wheel hub casting side mold drilling tool comprises a base plate 10, on which a locating seat 20 for fixing the side mold is provided corresponding to the side mold, and a locating surface 21 is provided on the locating seat 20 corresponding to the lower end surface of the side mold, wherein the locating surface 21 is inclined at a certain angle relative to the vertical direction. During use, the drilling tool is fixed to the machine tool processing platform via the base plate 10, and the side mold is fixed to the locating seat 20, ensuring that the lower end surface of the side mold is closely fitted with the locating surface 21 of the locating seat 20, so that the back cavity of the side mold fixed on the locating surface 21 is exposed under the machine tool drill bit. After the connection and fixation of the side mold and the locating seat 20 are completed, the machine tool can be started to perform vertical drilling operations on the inclined side mold, thereby forming a process hole with a certain inclined angle on the side mold.

[0021] This embodiment provides a positioning surface 21 with a certain tilt angle to tilt the side mold, achieving precise control of the drilling angle of the side mold process holes, standardizing the side mold drilling operation, ensuring the consistency of the processing holes of different side molds, and effectively avoiding the low processing accuracy and poor consistency of the process holes caused by traditional drilling operations. At the same time, it reduces the labor intensity of operators and ensures work efficiency.

[0022] As a preferred embodiment, a hanging plate 22 is provided on the positioning seat 20, and a through fixing hole is opened on the hanging plate 22 corresponding to the side mold connection hole. The connecting bolt passes through the fixing hole and is screwed into the side mold connection hole to complete the connection and fixation of the side mold and the positioning seat 20.

[0023] In a further embodiment, the positioning base 20 is rotatably connected to the base plate 10, allowing the tilt angle of the positioning surface 21 to be adjustable, thereby meeting the drilling requirements of process holes at different angles and expanding the applicability of the drilling tool. When processing process holes with different tilt angles, the tilt angle of the positioning surface 21 can be adjusted by adjusting the tilt angle of the positioning base 20 relative to the base plate 10, so that the side mold fixed to the positioning surface 21 is positioned at the desired tilt angle, thereby achieving process holes of different tilt angles. This makes the drilling tool of this utility model have a certain degree of versatility and saves on-site tooling production and management costs.

[0024] Specifically, an ear plate 11 is fixedly connected to the base plate 10, an axial hole is opened on the ear plate 11, and a rotating hole corresponding to the axial hole is opened on the positioning seat 20. The rotating shaft 12 passes through the axial hole of the ear plate 11 and is connected to the rotating hole of the positioning seat 20, thereby realizing the rotational connection between the positioning seat 20 and the base plate 10.

[0025] Preferably, the bottom plate 10 is provided with a locking mechanism corresponding to the positioning seat 20, for locking the turning angle of the positioning seat 20. The locking mechanism comprises a locking bolt 31 horizontally slidingly connected to the bottom plate 10, and the positioning seat 20 is provided with locking tooth grooves 32 corresponding to the locking bolt 31, and the locking tooth grooves 32 are spaced apart at different inclination angles. In use, the locking bolt 31 is inserted into the corresponding locking tooth groove 32, so as to limit the turning of the positioning seat 20 and achieve the locking of the turning angle of the positioning seat 20.

[0026] Preferably, the bottom plate 10 is provided with a sliding groove 33, and the locking bolt 31 is interactively connected in the sliding groove 33, so as to limit the movement track of the locking bolt 31 and ensure the stability. The locking bolt 31 and the sliding groove 33 can adopt dovetail matching or T-shaped sliding block and T-shaped groove sliding matching structure, so that the locking bolt 31 only has the freedom in the horizontal direction relative to the sliding groove 33, and the locking bolt 31 is prevented from being pulled out of the sliding groove 33, thereby affecting the locking stability.

[0027] Preferably, the locking bolt 31 is provided with a locking screw 36, and the locking screw 36 can penetrate the locking bolt 31 and be screwed to the bottom plate 10. When the positioning seat 20 is adjusted to the appropriate angle, the locking bolt 31 is inserted into the corresponding locking tooth groove 32, and the locking screw 36 penetrating the locking bolt 31 is screwed to the bottom plate 10, so as to achieve the position locking of the locking bolt 31 and further ensure the locking stability of the positioning seat 20.

[0028] Preferably, the tail end of the locking bolt 31 is provided with a compression spring 34, and the bottom plate 10 is provided with a supporting block 35 corresponding to the tail end of the compression spring 34, so as to press the compression spring 34 against the locking bolt 31. The compression spring 34 provides a pre-tightening force for the locking bolt 31, thereby further improving the operation stability of the locking mechanism.

[0029] In the embodiment, the locking screw 36 can be used as a handle for pulling the locking bolt 31. During adjustment, the locking screw 36 is held and pulled backward, so as to overcome the elastic force of the compression spring 34 and drive the locking bolt 31 to slide backward in the sliding groove 33, so that the front end of the locking bolt 31 is separated from the locking tooth groove 32. After the positioning seat 20 is turned to complete the inclination angle adjustment, the locking screw 36 is released, the compression spring 34 pushes the locking bolt 31 to slide forward, and the front end of the locking bolt 31 is clamped in the corresponding locking tooth groove, and the locking screw 36 is screwed to the bottom plate 10, so as to complete the angle adjustment and locking of the positioning seat 20.
