[0023] Refer to Figures 1-6 , a hole-opening device for processing a metal shell, including a machine platform 1, a lifting seat 3 is installed on one side of the upper part of the machine platform 1, an installation table 7 is installed in the middle of the lifting seat 3 through a lifting table 6, a locking handle 8 is rotatably installed in the middle of the installation table 7, a driving gear 81 is connected to the bottom of the locking handle 8, and extension tables 9 are connected by pinching through tooth grooves 91 on both sides of the driving gear 81, and a drilling head 10 is installed in the middle of the extension table 9 through a driving motor 5.

[0024] Furthermore, screw clamp assemblies 2 are installed on both sides of the machine platform 1.

[0025] Furthermore, a lead screw motor 41 is installed at the bottom of the lifting seat 3, the output end of the lead screw motor 41 is drivingly connected to a lead screw 4, the other end of the lead screw 4 is rotatably installed on the inner top wall of the lifting seat 3, and a lifting table 6 is screwed on the lead screw 4.

[0026] Furthermore, a rotating seat 14 is installed in the middle of the installation table 7, a shallow groove is opened in the middle of the rotating seat 14, a circle of ridges 141 are installed in a circular array on the upper part of the shallow groove, and a through hole is opened in the middle of the shallow groove, the locking handle 8 is rotatably installed in the through hole, one end of the locking handle 8 passes through the bottom wall of the rotating seat 14 and is connected to the driving gear 81, and a protrusion 15 is provided at the bottom end of the locking handle 8, and the protrusion 15 is in pressing contact with the ridges 141.

[0027] Furthermore, slide grooves 12 are provided on both sides of the bottom of the installation table 7, extension tables 9 are installed in the slide grooves 12 in a limited sliding manner, and a tooth groove 91 is opened on one side of each extension table 9, and the tooth groove 91 is meshed with the driving gear 81 provided in the middle of the bottom end of the installation table 7.

[0028] Furthermore, a pair of support rods 11 are provided on one side of the lifting table 6, and one end of the support rod 11 extends into the limit groove 18 opened in the middle of the installation table 7.

[0029] Furthermore, a plurality of grooves are provided on the support rod 11, and the support rod 11 is slidably installed in the limit groove 18, a mounting groove 13 is provided on one side of the top end of the inner wall of the limit groove 18, a limit ball 17 is installed in the mounting groove 13 through a spring 16, and the limit ball 17 protrudes out of the mounting groove 13 and fits with the groove provided on the upper part of the support rod 11.

[0030] In this embodiment, the metal shell to be processed is placed on the machine table 1, and the workpiece is clamped and fixed by the screw clamp assemblies 2 arranged on both sides of the machine table 1, and then the locking handle 8 arranged in the middle of the mounting table 7 is manually rotated, and the locking handle 8 is rotated to drive the driving gear 81 to rotate. The driving gear 81 is connected to the extension tables 9 on both sides through the tooth groove 91, so that the extension table 9 moves horizontally under the action of the gear rotation, and then the extension tables 9 on both sides of the mounting table 7 move synchronously. At this time, the drilling head 10 arranged in the middle of the extension table 9 is aligned with the specified opening point of the workpiece, and the screw motor 41 is started to drive the mounting table 7 downward. At this time, the driving motor 5 drives the drilling head 10 to rotate to open a hole in the workpiece.

[0031] Then, the mounting table 7 is manually pulled to move the entire mounting table 7 onto the support rod 11, and when it moves to the hole opening point on the other side of the shell, the drilling head 10 is used to perform hole opening operations. When the holes are opened on both sides of the shell, the mounting table 7 always maintains horizontal and translational movement, thereby ensuring the symmetry and accuracy between each hole.

[0032] In actual use, when the locking handle 8 is rotated, the protrusion 15 arranged at the bottom thereof is squeezed and contacted with the protrusion 141 arranged in the rotating seat 14, and a certain damping force and clear feedback feeling are generated during rotation, which helps the operator to adjust and avoids the locking handle 8 from turning upside down.

[0033] Among them, in actual use, a plurality of grooves are opened on the support rod 11. When the mounting platform 7 moves on the support rod 11, the limiting ball 17 arranged inside it is squeezed and contacted with the groove, and the mounting platform 7 is limited as a whole. When the mounting platform 7 moves, the limiting ball 17 is separated from the groove and pressed against the outer wall of the support rod 11. When it moves to another groove, it is pushed back and embedded in the groove through the spring 16. The principle is easy to understand intuitively and will not be explained here.

[0034] In the utility model, the metal shell to be processed is placed on the machine table 1, and the locking handle 8 is adjusted to change the position of the extension table 9 on both sides, so that the drilling spacing of the drilling head 10 is changed to adapt to the hole opening position of the shell. At the same time, the drilling head 10 is driven downward by the motor assembly to drill holes, so that symmetrical and precise holes can be opened on both sides of the shell. At the same time, four symmetrical holes can be opened by adjusting the overall position of the mounting table 7. The process is not only efficient and easy to operate, but also effectively improves the hole opening accuracy and ensures the processing efficiency.

[0035] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
