[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figs. 1-3 As shown, a drilling device for processing pins includes a worktable 2, a rotating frame 3 rotatably connected to the worktable 2, and a plurality of tapered slits 14 for accommodating pins 11 are opened on the outer side of the rotating frame 3 along its circumference. A positioning drilling mechanism 1 is fixedly connected above the worktable 2 at a position corresponding to the tapered slits 14. Preferably, the tapered slits 14 are opened along the radial direction of the rotating frame 3.

[0026] The positioning and drilling mechanism 1 includes a first movable frame 5 driven by a linear drive mechanism 4 to reciprocate radially along a rotating frame 3. A second movable frame 8 is slidably connected to the first movable frame 5. A stop block 10 is provided on one side of the second movable frame 8 corresponding to the conical cut 14. A buffer spring 7 is provided between the other side of the second movable frame 8 and the support of the first movable frame 5. A drilling device 6 is fixedly connected to the first movable frame 5 at a position corresponding to the pin 11. Preferably, the first movable frame 5 is slidably connected to the worktable 2 via a slide rail, and the second movable frame 8 is slidably connected to the first movable frame 5 via a slide rail.

[0027] In use, the pin 11 is placed in the conical cut 14 and the end cap of the pin 11 is attached to the rotating frame 3. The rotating frame 3 is driven to rotate until it reaches the positioning and punching mechanism 1. Then, the first movable frame 5 is driven to move towards the rotating frame 3 by the linear drive mechanism 4. The abutment 10 is inserted into the conical cut 14. Under the combined action of the abutment 10 and the conical cut 14, the pin 11 is clamped and fixed. The linear drive mechanism 4 continues to push the punching device 6 towards the rotating frame 3. The buffer spring 7 is compressed by force, and the punching device 6 gradually approaches the pin 11 and punches it. After punching is completed, the linear drive mechanism 4 drives the punching device 6 to reset.

[0028] By setting a tapered slit 14 and a stop block 10 to clamp the pin 11, and then the drilling device 6 performs the drilling operation, the positioning and drilling are made more convenient. In addition, by setting multiple tapered slits 14 on the rotating frame 3, loading and unloading operations can be performed at other tapered slits 14 during the drilling process, reducing the time required for loading and unloading and improving processing efficiency.

[0029] To prevent the pin 11 from detaching from the conical cut 14 under centrifugal force during the rotation of the rotating frame 3, a limiting ring groove 13 adapted to the end cap of the pin 11 is provided at the top of the conical cut 14. After the pin 11 is placed in the conical cut 14, the limiting ring groove 13 limits the end cap of the pin 11, thereby preventing the pin 11 from detaching from the conical cut 14 under centrifugal force.

[0030] In some embodiments, in order to prevent the pin 11 from shifting position after being pressed, which would cause the drilling position to shift, two abutments 10 are rotatably arranged on the second movable frame 8. The two abutments 10 press the pin 11 from both sides to prevent the pin 11 from shifting.

[0031] Specifically, a return spring 15 is provided between the two abutments 10, and the two ends of the return spring 15 are fixedly connected to the two abutments 10 respectively. By setting the return spring 15, the distance between the two abutments 10 can be controlled to prevent the distance between them from being greater than the width of the conical cut 14, which would prevent them from being inserted into the conical cut 14. At the same time, it also prevents them from getting too close to each other and losing the effect of squeezing and positioning from both sides.

[0032] Specifically, each of the two abutment blocks 10 is fixedly connected to a synchronizing gear 9 at one end of its rotatable connection to the second movable frame 8, and the two synchronizing gears 9 mesh with each other. By setting two synchronizing gears 9, the two abutment blocks 10 rotate synchronously, preventing them from shifting to one side and affecting positioning.

[0033] To further improve processing efficiency, there are multiple positioning and drilling mechanisms 1, each corresponding to a different tapered cut 14.

[0034] By setting multiple positioning and drilling mechanisms 1, multiple pins 11 can be positioned and drilled simultaneously. Preferably, the number of abutments 10 is twice the number of positioning and drilling mechanisms 1.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
