Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to an automatically clamped numerically controlled lathe. Background Art

[0002] CNC lathes are one of the most widely used machine tools. They are mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads. They can also perform grooving, drilling, reaming, reaming and boring, etc. They have various functions. However, with the diversity of processing needs, the current CNC lathes are more troublesome to operate in the process of processing long workpieces due to safety and disassembly restrictions.

[0003] In recent years, with the further development of relevant technologies, technical solutions that can solve the above-mentioned lathe processing problems have emerged in the prior art. For example, the patent document with application number 202321080461.5 proposes "a CNC lathe capable of automatic clamping, through the coordinated use of a telescopic cylinder, a loading push plate and a clamping fixing ring. When in use, the workpiece to be clamped is placed on the loading push plate, and the telescopic cylinder drives the loading push plate upward through the push rod to transfer the workpiece to the clamping fixing ring, replacing the traditional manual lifting method, reducing the work intensity of the staff, and then the electric push rod drives the clamping fixing plate to automatically clamp the workpiece, without the need for manual adjustment of the clamping by the staff, which is convenient and quick."

[0004] From the technical effect of the implementation of the above-disclosed technical content, it can provide auxiliary clamping support for lathe workpieces and installation. However, the actual CNC lathe has a small internal space, and the support and installation structure proposed in the above-mentioned patent document needs to occupy a large space in the CNC lathe before it can operate. Secondly, when the additional space is large, structural interference may occur in the processing of the CNC lathe itself. Utility Model Content

The two electromagnetic suction cups are respectively installed on the top inner wall and the bottom inner wall of the semi-developed frame plate, and the two magnet blocks are respectively installed on the surfaces of the two clamping plates. The magnetic transmission component is used in conjunction with the elastic clamping plate, and then utilizes its own reciprocating magnetic exclusion and resetting pressure output effect to enable the elastic clamping plate to actively move, thereby meeting the contact clamping conditions for the long rod raw materials.

The outer protective shell is fixedly connected to the surface of the bottom side of the adjustment support plate. The pressure-sensitive detection component is linked to the detection rod to record the pressure state of the lifting and lowering amplitude of the detection rod in a concrete way.

[0014] The detection rod comprises a second T-rod, a supporting sleeve, and a second spring.
