New description: [New technical field] The main purpose of this creation is to provide a synchronous machine tool for processing machinery, which uses the ATC to drive the tool arm to the knives and simultaneously complete the spindle knives. To save the time for the loose-knife cylinder to wait for the arm to turn to the knife point. ^ [Prior Art] Conventional machining center machine is equipped with a motor connected to the electric control device on the support frame. The motor drives the cam shaft and the arm main shaft mounted on the support frame through the transmission device. The action, the rotation of the spindle of the tool arm and the axial movement can realize the tool change action. During the tool change process, the tool arm firstly clamps 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 knife is driven by the camshaft through the chain of the sprocket chain. The sprocket is inductively controlled. The disadvantage is that the arm is prone to jitter when the tool is changed, resulting in a smooth and unstable tool change and loose knife action, and has safety concerns. The creator of this creation is engaged in the rapid tool change mechanism of the machining center machine and its related products. It is known for its advantages and disadvantages for many years. It is committed to improving its shortcomings, making the knife-making mechanism more practical and meeting the needs of users. The experiment was improved, and finally the creation of a processing machine for the same machine. 3 M433922 [New Content] The main purpose of this creation is to provide a synchronous machine tool for processing machinery, which uses the ATC to drive the tool arm to the knives and simultaneously complete the spindle knives to save the loose knives. Waiting for the time when the knife arm is turned to the buckle point, which uses a chain to drive the cam, and the cam rotates to drive the same action knife mechanism at the same time, causing the cam drive to move the same mechanism to lower the spindle to complete the loose knife, and the same motion The knife loosening mechanism includes: a base body, a cylinder, a reset top rod, a rocker, a force rod bracket, a force applying rod, an adjusting rod and a knife arm, and a cylinder is arranged on one side of the base body, and the middle portion is provided There is a force-applying rod bracket, and a resetting ejector is arranged on one side of the force-applying rod bracket, and a connecting shaft is arranged on the force-applying rod bracket, and one end of the connecting shaft is provided with a rocking rod and the other end is provided with a force-applying rod, and one end of the force-applying rod is provided The adjusting rod is provided with a knife arm at the bottom end of the adjusting rod, and the knife arm is provided with the knife arm, that is, the same moving knife mechanism of the processing machine is completed. [Embodiment] Please refer to the same action cutter mechanism of the processing machine shown in the first to fifth figures, which uses a chain (10) to drive the cam (11), and the cam (11) rotates to drive the same motion. The cutter mechanism (20) causes the cam (10) to drive the synchronous cutter mechanism (20) to press down to cause the spindle (80) to complete the loose cutter, and the synchronous cutter loosening mechanism (20) comprises: the base of the base ( 30), cylinder (31), reset ejector (32), rocker (33), urging rod bracket (34), urging rod (35), adjusting rod (36) and tool arm (37), machine The seat body (30) is provided with a cylinder (31) on one side, a force applying rod bracket (34) at the middle portion, and a resetting rod (32) on one side of the force applying rod bracket (34) M433922, and the force rod bracket (34) A connecting shaft (341) is arranged on the upper side, and the connecting shaft (341) is provided with a rocker (33) at the other end and a biasing rod (35) at the other end, and the force applying rod (35) is pivotally connected to the adjusting rod. At the top of (36), the bottom end of the adjusting rod (36) is pivotally connected to the knife arm (37), the front end of the knife arm (37) is pivoted on the base body, and a pivot (371) is used at the middle of the (30) Wear the knife arm (37) and the spindle (80) , A bottom end pivoted to the rear end of the adjusting rod (36), namely the creation of an isotype completing the present processing machinery movable knife means hit. _ The above cam (11) can drive the rocker (33) to shift, and the rocker (33) is offset to drive the connecting shaft (341) and the urging force lever (35) to rotate and press. The lever (35)-end pivoting adjustment lever (36) presses the cutter arm (37), so that the cutter arm (37) presses the spindle (80) to loosen the knife, and completes the spindle (80) loosening action, and The reset ejector pin (32) can push the urging rod (35) back to the state before the spindle (80) is not loosened after the loose knives are completed. An adjusting screw (362) is arranged in the middle of the adjusting rod (36), a nut (361) is arranged on the adjusting screw (362), and a φ connecting shaft (363) is screwed on both ends of the adjusting screw (362), thereby rotating the nut ( 362) Adjust the distance between the connecting shafts (363) at both ends to make the cutting arm (37) press the main shaft (80) to loosen the cutter more accurately and labor-saving.
