Description

Technical Field

[0001] The invention relates to the field of drilling equipment, in particular to an automatic drilling equipment for a motor end cover. Background Art

[0002] The motor end cover is a back cover installed on the motor casing. It is usually a circular structure and needs to have multiple threaded holes drilled around it for connection and fixation. Most of the holes on the motor end cover are parallel to its axis, but some motor end covers also need to have multiple holes drilled perpendicular to its axis.

[0003] Chinese patent publication number CN110170684B discloses a jig for drilling holes on the circumferential surface of a water pump motor end cap. The jig utilizes nylon rollers and an adjustable mandrel to ensure rotational flexibility and stability throughout the entire operation, meeting requirements for quick clamping and easy rotation during drilling. This makes the process faster, more convenient, and safer, significantly reducing operator workload and improving productivity.

[0004] However, the above-mentioned disclosed solution has the following shortcomings: The loading, unloading, and angle adjustment of the motor end cap require the drilling process to be suspended, resulting in very low drilling efficiency. Furthermore, the loading, unloading, and angle adjustment of the motor end cap require manual operation, making drilling a single workpiece labor-intensive. Furthermore, the equipment can only drill radial holes in the motor end cap, and cannot simultaneously drill axial holes in the motor end cap. This may require a separate process to complete the axial hole drilling. Summary of the Invention

[0040] Example 4, as Figure 2 As shown, the present invention proposes an automatic drilling device for a motor end cover. Compared with the first embodiment, this embodiment introduces the structure of the hole opening component and the tapping component in detail.

[0041] The hole-opening assembly includes a support plate a26 arranged at the bottom of the top plate 3, a radial drilling device 27 arranged on the support plate a26, and an axial drilling device 28 arranged at the bottom of the top plate 3.

[0043] Example 5, as Figure 4-Figure 5 As shown, the present invention proposes an automatic drilling device for a motor end cover. Compared with the fourth embodiment, this embodiment introduces the structure of the secondary positioning mechanism in detail.

[0044] The secondary positioning mechanism is used to provide secondary positioning support for the swing support mechanism at the hole opening position and the tapping position. Specifically, the secondary positioning mechanism includes a secondary positioning rod 19 arranged on the support plate 12, a support plate b33 arranged at the bottom of the top plate 3, a telescopic device 32 arranged on the support plate b33, and a secondary positioning cylinder 31 arranged at the telescopic end of the telescopic device 32.

[0045] In summary, when the present invention is in use, the operator places the motor end cover 15 on the workpiece placement seat 14 at the loading position, and installs the pressure plate 16 in place, and presses the motor end cover 15 by the pressure plate 16. Then the lifting device 24 drives the slide plate 22 to descend, and the support plate 12 rotates downward under the action of its own weight. Then, the power box 8 drives the rotating sleeve 5 to rotate ninety degrees, and then the lifting device 24 extends and pushes the support plate 12 up again. The hole-punching assembly completes the axial and radial drilling of the motor end cover 15 at the hole-punching position, and then the support plate 12 rotates downward again, and the rotating sleeve 5 continues to rotate ninety degrees. The support plate 12 rotates upward again, and the radial and axial tapping of the motor end cover 15 is completed by the tapping assembly at the tapping position. Then, after the support plate 12 rotates downward again, the rotating sleeve 5 rotates ninety degrees again, and then the support plate 12 rotates upward again to a horizontal state. At this time, the processed motor end cover 15 enters the unloading position, and the operator can remove the motor end cover 15. During the entire drilling process, the operator's loading and unloading will not affect the normal progress of the drilling and tapping positions, greatly improving the drilling efficiency of the motor end cover 15. The motor end cover 15 does not require personnel to adjust the drilling angle, making it more convenient to use. At the same time, all radial holes 20 and axial holes 21 are drilled and tapped, and there is no need to continue processing through other processes. The radial drilling device 27, the axial drilling device 28, the radial tapping device 29 and the axial tapping device 30 are fixed in position, and the transfer between processes is completed by the up and down swinging of the motor end cover 15. The fixation of the power structure for drilling and tapping can guarantee long-term processing accuracy to the greatest extent. In addition, by setting a secondary positioning mechanism, the processing position of the motor end cover 15 can be further guaranteed, thereby ensuring processing accuracy.

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
