Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a numerical control machine tool with a protective function. Background Art
[0002] CNC machine tools are an important type of metal processing machine tools, which are widely used in the machinery manufacturing industry. CNC machine tools can perform complex processing operations. CNC machine tools are usually composed of multiple parts such as the machine tool body, control system, tool, transmission system, etc., and are operated and controlled by computers;
[0003] In the current design of CNC machine tools, although protective doors exist, they can be opened at will. This design defect greatly increases the safety risk of operators, because once the protective door is opened, the operator may accidentally touch the rotating tool or flying workpiece, causing serious injury. In addition, when the protective door is opened, an early warning cannot be issued in the first time, and the staff cannot be reminded in time, which increases the potential risk.
[0004] In order to solve the above problems, the present application proposes a CNC machine tool with a protective function. Utility Model Content
[0005] Based on the technical problems existing in the background technology, the utility model proposes a CNC machine tool with a protective function.
[0006] The utility model provides a CNC machine tool with a protective function, comprising a CNC machine tool body and a protective door installed on the CNC machine tool body;
[0007] A spherical part located below the protective door is installed on the CNC machine tool body, a fixed cylinder is movably installed on the spherical part, an insertion cavity is opened in the fixed cylinder, a pressure warning part is installed at the bottom of the insertion cavity, an elastic pressure part inserted into the insertion cavity and abutting against the pressure warning part is provided on the fixed cylinder, and an adsorption part adsorbed on the protective door is installed on the elastic pressure part.
[0008] Preferably, the spherical member includes a ball seat and a ball, the ball seat is mounted on the CNC machine tool body and is located below the protective door, a rolling groove is provided on the top of the ball seat, the ball is rollingly connected in the rolling groove, and the fixing cylinder is mounted on the top of the ball.
[0009] Preferably, the pressure warning component includes a pressure sensor and a buzzer, the pressure sensor is installed at the bottom of the insertion cavity, the buzzer is installed on the outer periphery of the fixed cylinder, and the pressure sensor is electrically connected to the buzzer.
[0010] Preferably, the elastic pressure piece includes an end block, a pressure rod and a spring, the pressure rod is inserted in the insertion cavity and abuts against the pressure sensor, the end block is installed on the top end of the pressure rod, the spring is sleeved on the pressure rod and located between the end block and the fixed tube, and the two ends of the spring are respectively connected to the end block and the fixed tube.
[0011] Preferably, the adsorption component includes an elastic rod and a fixed block, the elastic rod is mounted on the end block, the fixed block is mounted on an end of the elastic rod away from the end block, and a suction cup adsorbed on the protective door is mounted on the fixed block.
[0012] The above technical solution of the utility model has the following beneficial technical effects:
[0013] The adsorption piece on the elastic pressure piece can be adsorbed on the protective door. When the CNC machine tool body is in operation, the staff opens the protective door at will. The adsorption piece adsorbed on the protective door is forced to pull the elastic pressure piece in the fixed cylinder upward, and the elastic pressure piece immediately undergoes elastic deformation to play a limiting role. The fixed cylinder moves on the spherical part. After the elastic pressure piece moves away from the pressure warning part, the pressure on the pressure warning part changes and an alarm is issued. This structure can play a certain limiting role on the protective door on the CNC machine tool body, prevent the staff from opening the protective door at will, and can issue an alarm in time when it is opened a little, thereby ensuring the safety of the staff.

[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0018] like Figure 1 and Figure 2 As shown, the utility model provides a CNC machine tool with a protective function, comprising a CNC machine tool body 1 and a protective door 2 installed on the CNC machine tool body 1;
[0019] In this embodiment, a ball member 3 is installed on the CNC machine tool body 1 and is located below the protective door 2. A fixing cylinder 4 is movably installed on the ball member 3. The ball member 3 includes a ball seat 31 and a round ball 32. The ball seat 31 is installed on the CNC machine tool body 1 and is located below the protective door 2. A rolling groove is opened on the top of the ball seat 31. The round ball 32 is rollingly connected in the rolling groove. The fixing cylinder 4 is installed on the top of the round ball 32.
[0020] In this embodiment, an insertion cavity is provided in the fixed cylinder 4, and a pressure warning component 5 is installed at the bottom of the insertion cavity. The pressure warning component 5 includes a pressure sensor 51 and a buzzer 52. The pressure sensor 51 is installed at the bottom of the insertion cavity, and the buzzer 52 is installed at the periphery of the fixed cylinder 4. The pressure sensor 51 and the buzzer 52 are electrically connected.
[0021] In this embodiment, the fixed cylinder 4 is provided with an elastic pressure piece 6 inserted into the insertion cavity and abutting against the pressure warning piece 5. The elastic pressure piece 6 includes an end block 61, a pressure rod 62 and a spring 63. The pressure rod 62 is inserted into the insertion cavity and abuts against the pressure sensor 51. The end block 61 is installed on the top of the pressure rod 62. The spring 63 is sleeved on the pressure rod 62 and is located between the end block 61 and the fixed cylinder 4, and the two ends of the spring 63 are respectively connected to the end block 61 and the fixed cylinder 4.
[0022] In this embodiment, an adsorption member 7 adsorbed on the protective door 2 is installed on the elastic pressure member 6. The adsorption member 7 includes an elastic rod 71 and a fixed block 72. The elastic rod 71 is installed on the end block 61, and the fixed block 72 is installed at one end of the elastic rod 71 away from the end block 61. A suction cup 73 adsorbed on the protective door 2 is installed on the fixed block 72.
[0023] It should be noted that in order to limit the protective door 2 and to sound an alarm when it is opened, when the CNC machine tool body 1 is in operation, the staff opens the protective door 2 at will, and the suction cup 73 adsorbed on the protective door 2 pulls the end block 61 and the pressure rod 62 upward through the elastic rod 71 under the action force. At the same time, the fixed cylinder 4 drives the ball 32 to roll on the ball seat 31. Under the action force, the pressure rod 62 slides in the insertion cavity opened in the fixed cylinder 4, and the spring 63 between the end block 61 and the fixed cylinder 4 is deformed immediately to play a limiting role. After the pressure rod 62 moves away from the pressure sensor 51, the pressure on the pressure sensor 51 will change, and then the pressure signal will be transmitted to the buzzer 52, and an alarm can be sounded through the buzzer 52. This structure can play a certain limiting role on the protective door 2 on the CNC machine tool body 1, prevent the staff from opening the protective door 2 at will, and can sound an alarm in time when it is opened a little, thereby ensuring the safety of the staff.
