Loose clamping knife mechanism of double force linkage processing machine

The present invention belongs to a loose-clamping mechanism of a double-strength linkage processing machine, which uses a pair of output shaft cylinders to press the cutter arm, so that the cutter arm is pressed down to make the spindle complete the loose cutter, and the fulcrum of the cutter arm Longer and increased the angle of the knife, the double-outlet cylinder is more labor-saving and increases the service life. The longer the fulcrum of the arm increases the angle of the knife, and the manual knives are also more labor-saving. The rotating shaft, the rocker arm, the knife pressing lever, the connecting rod and the knife arm are integrally connected, and the failure rate can be reduced when the knife is operated.

According to the conventional machining center machine, a main motor connected to the electric control device is mounted above the main shaft, and the main motor drives an external cylinder through the sensing device to operate the cutter cylinder built in the main shaft. , to complete the spindle cutter loosening action.

During the tool change process, the tool arm firstly buckles the tool on the tool magazine, and then the electronic control device drives the tool magazine to perform the action of the loose knife. At present, the action of the loose knife is driven by the camshaft through the sprocket chain to drive the signal sprocket. The disadvantage of the induction control is that the number of starts and stops of the arm motor is easy to wear when the tool is changed, and the assembly error of the multiple parts is inevitable. Accumulated error is inevitable, so that the action of the loose knife is not timely, the knife and the knife are The action of the loose knife cannot be carried out at the same time, that is, it must wait for one after the knife is buckled. It takes a certain time to loosen the knife, resulting in a long tool change time, resulting in low processing efficiency, unsmooth movement, incoherence, instability, and safety concerns.

The creators of this new type have been aware of their advantages and disadvantages for many years in the manufacture of tool magazine structures and related products. They are committed to improving their shortcomings, making the structure of the tool magazine more practical and meeting the needs of users. A loose-clamp mechanism for a double-link processing machine was created.

Therefore, the purpose of the present invention is to provide a synchronous cutter structure of a processing machine, which uses the ATC to drive the cutter arm to the machining center while simultaneously completing the spindle loose clamp and the tool change program to save the machining center. The time of automatic tool change is to use a pair of output shaft cylinders to press down the knife arm, so that the tool arm is pressed down to make the spindle complete the loose clamping knife, so as to complete the manual manual tool change, the structure includes: a lock a pair of shaft cylinders, a shaft, a rocker arm, a knife bar, a connecting rod, a knife arm, a plurality of buffer reset cylinders and an inductor, and a pair of shaft cylinders are arranged above the lock seat, A cylinder shaft is arranged at the front end of the shaft cylinder, and a cylinder stroke limit block is arranged at the rear end of the cylinder shaft. The front end of the cylinder shaft is provided with a top seat. The top of the locking seat is provided with an inductor at a suitable position, and a rotating shaft is disposed at a middle portion of the locking seat. A rocker arm is arranged on one side, and a knife pressing lever is arranged at a middle portion of the rotating shaft, and a reset bearing is arranged at a front end of the knife pressing rod. The front end of the front end of the knife pressing rod is provided with a connecting rod, and the front end of the connecting rod is pivoted. Knife arm, the front end of the knife arm is forked to form ㄇ The pivoting arm has a knife bearing in the middle section of the shackle of the shackle at the two ends, and a arbor support shaft is arranged at the front end of the 枢-shaped pivoting arm, and a spacer ring is arranged on the arbor of the arbor arm, and the middle section of the arbor arm is provided The end is provided with a perforation as a pressure point, and the perforated inner pivot is provided with a pivot rod and a knife arm The end pivot is provided with a roller, that is, the loose clamping knife mechanism of the double-strength link processing machine of the present invention is completed.
