[0002] The tensioner pulley is an important component in the belt drive system of an automotive engine. Its function is to maintain the tension of the belt through an elastic structure or bearing support mechanism, thereby preventing the belt from slipping or falling off. In order to install balance weights, detection elements, or for weight reduction and heat dissipation on the outer wall of the tensioner pulley, it is usually necessary to make multiple holes evenly distributed on its outer wall.

[0003] Most existing tensioner drilling equipment adopts a single-station drilling structure. The workflow is that the tensioner to be processed is manually placed into the fixture, and then the drilling machine completes the drilling. After that, the finished tensioner is manually removed, a new workpiece is replaced, and the drilling machine is restarted for the next drilling. During the process, the machine needs to be stopped and the workpiece needs to be manually disassembled after each drilling, resulting in long equipment downtime and low production efficiency.

[0004] Based on this, this utility model designs a high-efficiency drilling device for tensioning wheels to solve the above problems. Summary of the Invention

The top of the mounting column 6 is provided with a material trough 10. Two symmetrical cranks 7 are hinged to the outer wall of the mounting column 6. A clamping arm 8 is hinged to the end of the crank 7 near the hinge. Both clamping arms 8 are U-shaped and the end away from the hinge extends to the top of the material trough 10. They are vertically threaded with a clamping bolt 9 to clamp the tensioning wheel to be drilled in the material trough 10. The servo drive motor of the existing rotary table driver 2 on the machine tool 1 drives the rotary table 3 to rotate cyclically, realizing continuous drilling at multiple stations. The mounting column 6 is used to position the tension wheel, and the clamping arm 8 and the crank 7 form a lever structure. The downward clamping force is generated by the tightening bolt 9, which makes the tension wheel stable and does not wobble during the drilling process. It achieves efficient clamping and rapid indexing, which greatly improves the drilling stability and processing efficiency.

[0017] More preferably, a mounting base 12 and a support arm 15 are fixedly connected to the top of the machine base 1, and a drill 13 and a photoelectric sensor counter 14 are fixedly installed on the outer wall of the mounting base 12, and the drill bit end of the drill 13 and the sensing end of the photoelectric sensor counter 14 are both vertically facing the material trough 10 of the corresponding mounting column 6. A mounting base 12 and a support arm 15 are installed on the machine base 1. The drilling rig 13 and the photoelectric induction counter 14 are fixed to the mounting base 12, forming a vertically aligned drilling and detection channel. After the drilling rig 13 completes drilling, the induction counter automatically detects the processing signal, realizing the monitoring of the number of holes drilled or the processing cycle. This improves drilling accuracy and automatic detection efficiency.

[0018] More preferably, a display 16 is fixedly installed at one end of the support arm 15, and a master controller is set inside the machine base 1. The control terminals of the drilling rig 13, photoelectric induction counter 14, display 16 and rotary table driver 2 are all electrically connected to the master controller. The master controller has a built-in PLC system for realizing automatic control of drilling, indexing, counting and data display. By installing a central controller and a built-in PLC system within machine 1, centralized electrical control of the drilling rig 13, photoelectric counter, display 16, and rotary table driver 2 is achieved. The PLC system automatically executes drilling, counting, indexing, and data display logic without manual intervention. This enables the equipment to perform automated cyclic processing, significantly improving production efficiency and operational safety.

[0019] More preferably, the outer wall of the base 4 is provided with a plurality of first connecting holes 5, and the outer wall of the turntable 3 is provided with threaded grooves corresponding to the first connecting holes 5, for locking the base 4 to the turntable 3 with bolts; By setting a first connecting hole 5 on the outer wall of the base 4 and a corresponding threaded groove on the outer wall of the turntable 3, the bolts of the base 4 and the turntable 3 can be detachably locked. This ensures the stability of the base 4 when the turntable 3 rotates and facilitates quick disassembly and replacement of tooling of different specifications.

[0020] More preferably, the bottom end of the mounting column 6 is provided with a plurality of second connecting holes 11, and the outer wall of the base 4 is provided with threaded grooves corresponding to the second connecting holes 11, for locking the mounting column 6 to the base 4 with bolts; By opening a second connecting hole 11 at the bottom of the mounting column 6 and setting a corresponding threaded groove on the outer wall of the base 4, a detachable locking connection is made using bolts, ensuring that the mounting column 6 is installed firmly and is easy to replace.

[0021] One specific application of this embodiment is as follows: the tensioning wheel to be drilled is placed into the material groove 10 of the mounting column 6, the crank 7 is rotated to control the clamping arm 8, so that the clamping arm 8 is symmetrically clamped on both sides of the tensioning wheel, and the tensioning wheel is firmly positioned by the pre-tightened abutment bolt 9 to the contact depth. During the processing, the clamping is completed in sequence at multiple stations. When the external power supply is started, the PLC system of the main controller enters the working mode, controls the turntable 3 to automatically rotate the first station to directly below the drill 13, controls the drill 13 to descend and drill, and after drilling is completed, rises and resets. Meanwhile, the photoelectric sensor counter 14 can detect the tension wheel in real time during the process, sends the signal count to the main controller, and switches to the display 16 to display the current processing quantity in real time. The station that has been drilled moves out for manual unloading or the next loading, realizing continuous and efficient processing.
