Description

Technical Field

[0001] The present invention belongs to the technical field of numerical control machine tools, and particularly relates to a turret head assembly of a numerical control turret punch press configured with a multi-specification die system. Background Art

[0002] A numerical control machine tool is short for a numerically controlled machine tool, which is an automated machine tool equipped with a program control system and can efficiently and accurately complete the processing of complex parts. A turret punch press is a relatively common numerical control machine tool, mainly used for operations such as punching, forming, and cutting of metal plates. A turret punch press mainly consists of a machine body frame, a turret head, a numerical control system, X / Y axis servo drives, a hydraulic power system, a feeding system, etc. Among them, the turret head, also generally known as a tool turret, is an important part of the turret punch press and is used to quickly switch different dies.

[0003] A prior art document with the authorized publication number CN118926551B discloses a power tool turret for a numerical control machine tool, including a tool turret base, and further including a tool disk body. The tool disk body is installed at one end of the tool turret base, and a tool disk drive shaft sleeve is provided between the tool disk body and the tool turret base. The tool disk drive shaft sleeve is used for the tool disk body to rotate at any angle on the tool turret base.

[0004] However, the following defects exist in the use process: 1. For the power tool turret disclosed in the above document, during use, the telescopic member drives the power rod to contract and extend, that is, the tool shaft is disengaged from the connecting claw, and then the rotating member drives the power rod to rotate a fixed angle, so that the connecting claw can be accurately connected to the adjacent tool shaft. Its structure is complex, and more energy is consumed when replacing the die. 2. For the power tool turret disclosed in the above document, during use, the tool shaft and the die are installed through the tool disk body. However, during use, since dies of different specifications are installed on multiple surfaces of the tool disk body and the weights of different specifications of dies are different, the weights of multiple surfaces of the tool disk body are inconsistent, resulting in an unstable center of gravity of the tool disk body. Furthermore, when the die rotates, vibration occurs due to the unstable center of gravity of the tool disk body, affecting the processing of the workpiece. 3. For the power tool turret disclosed in the above document, during use, the first driving member and the power rod drive the tool shaft to rotate, and the tool shaft drives the die to rotate, and the workpiece is processed by the rotating die. However, during use, due to the high-speed rotation of the die and the friction between the die and the workpiece, the temperature of the die rises. Excessive temperature will affect the service life and accuracy of the die.

[0005] Therefore, we provide a turret head assembly of a numerical control turret punch press configured with a multi-specification die system to solve the above problems. Summary of the Invention

The square rod 104a and the first limiting plate 104b are used to movably mount the first clamping joint 104 on the rotating cylinder 103. The return spring 105 is used to drive the first clamping joint 104 to approach the driving part 109. The electromagnet 106 is used to drive the first clamping joint 104 to move away from the driving part 109.

[0038] Specifically, first fixing rods 107a are welded to the periphery of the front end face of the fixing plate 107, and the front ends of the first fixing rods 107a are fixedly connected to the rear end face of the first turntable 108; Above the rear end face of the fixed plate 107, a first driving motor 107c is fixedly connected through a first motor bracket 107b. The output shaft of the first driving motor 107c is fixedly connected with an adjusting rod 107d.
