Example one
On the existing machine tool, the cable is always connected with the magnetic suction disc. When the machine tool is put into operation, the cable and the magnetic chuck vibrate to some extent. The cable is flexible and can be bent, so that the vibration frequency of the cable and the magnetic attraction disc cannot be completely consistent in the vibration process, and the interaction force generated by the vibration exists between the cable and the magnetic attraction disc.
Under such a long-term working condition, the connection between the magnetic chuck and the cable is damaged or broken due to stress fatigue.
In order to solve the above problems, the present embodiment provides a magnetic attraction device for a machine tool, through which the situation of damage, fracture, etc. of a cable due to vibration can be effectively avoided.
Referring to fig. 1, the magnetic attraction device for a machine tool includes an electric permanent magnetic chuck 1 and a power supply assembly for supplying power to the electric permanent magnetic chuck 1. For convenience of description, the magnetic attraction device for a machine tool will sometimes be referred to simply as a magnetic attraction device.
In this embodiment, the power supply unit includes a connector, the connector includes a male connector 2 and a female connector 4 connected to the cable 3, and the male connector 2 is detachably connected to the female connector 4.
The workpieces mentioned herein are all metal parts that are magnetically permeable, for example, metal parts of iron, steel, etc. The electric permanent magnetic chuck 1 can generate strong magnetic force after being electrified and magnetized, and can stably adsorb a workpiece. Wherein, the main body of the electric permanent magnetic chuck 1 can be arranged in a cylindrical or rectangular shape.
In this embodiment, the connector may be a heavy duty connector. The heavy-load connector has the advantages of high integration level, high protection level and the like.
In the actual use process, the manufacturer or the user can select other types of connectors according to the needs.
In the embodiment, by providing the connector and the driving device 5, the connection and the separation between the electric permanent magnetic chuck 1 and the cable 3 are realized, and thus, the functions and purposes of protecting the cable 3 and prolonging the service life of the cable 3 are achieved.
In order to understand the working principle of the magnetic attraction device more clearly, the following briefly describes the installation of the workpiece and the use of the magnetic attraction device:
placing a workpiece on the electric permanent magnetic chuck 1, and adjusting the position of the workpiece;
starting the driving device 5 to combine the female head 4 with the male head 2;
electrifying and magnetizing the electric permanent magnetic chuck 1 through the cable 3, so that the electric permanent magnetic chuck 1 is magnetized and fixes a workpiece;
the driving device 5 is started again, so that the female head 4 is separated from the male head 2;
starting a cutter to process a workpiece;
after the workpiece is machined, starting the driving device 5 to enable the female head 4 to be combined with the male head 2;
the electric permanent magnetic chuck 1 is electrified and demagnetized through the cable 3.
By last knowing, before processing the work piece, female head 4 on the cable 3 can with public first 2 separation on the electric permanent magnet sucking disc 1, except avoiding drive arrangement 5 to influence the normal work of lathe, can also avoid producing the interact power between cable 3 and the electric permanent magnet sucking disc 1, play the purpose of protection cable 3.
Because the cable 3 and the electric permanent magnetic chuck 1 can be separated, when the cable 3 goes wrong, the cable 3 can be directly replaced or repaired without disassembling the electric permanent magnetic chuck 1, and therefore the maintenance cost of the cable 3 is reduced.
When the workpiece is fixed and separated, the electric permanent magnetic chuck 1 needs to be electrified. In order to provide corresponding electrical energy, the power supply assembly further comprises a power source.
One end of the cable 3 is electrically connected with the power supply, and the other end of the cable 3 is electrically connected with the female head 4. Wherein, the power supply can adopt commercial power.
Before the workpiece is fixed by the magnetic attraction, the position of the workpiece needs to be adjusted, and therefore the workpiece needs to be positioned.
As shown in fig. 2, the electric permanent magnetic chuck 1 may be provided with a positioning pin 6 for positioning a workpiece, and a side surface of the workpiece or a hole on the workpiece may be positioned by the positioning pin 6.
It should be noted that the number and positions of the positioning pins 6 in fig. 2 are merely examples. In the actual installation and use process, the number and the positions of the positioning pins 6 can be set according to the size and the shape of the tool.
The positioning pin 6 and the electric permanent magnetic chuck 1 can be detachably connected, for example, screwed, inserted and connected.
Take a threaded connection as an example. The tip of locating pin 6 can be provided with the screw thread section, can be provided with the screw hole that corresponds with it on the electric permanent magnet sucking disc 1, so, locating pin 6 just can install on electric permanent magnet sucking disc 1 through the cooperation of screw thread section and screw hole.
In order to reduce the manufacturing cost, mounting holes may be provided directly on the electro-permanent magnetic chuck 1, wherein the positioning pins 6 are directly inserted into the corresponding mounting holes. To ensure stability, an interference fit may be used between the locating pin 6 and the mounting hole.
After the positioning of the workpiece is completed, the male head 2 and the female head 4 need to be connected. In the present embodiment, the male head 2 and the female head 4 are coupled and decoupled by the driving device 5.
The driving device 5 may use a three-axis motion mechanism, but such a mechanism is costly, complicated and takes up a large space.
In order to reduce the cost and the occupied space, the driving device 5 can adopt a linear driving module. Wherein, the linear driving module can be fixedly arranged on the machine tool.
Preferably, the linear driving module can adopt any one of an air cylinder, a hydraulic cylinder or an electric push rod. In the actual use process, however, other linear motion mechanisms or devices can be selected by manufacturers or users according to the needs.
In this embodiment, the female head 4 can be fixedly disposed on the driving member of the linear driving module. Wherein, the female head 4 can be fixed on the driving piece by bolt connection and other modes. For example, a through hole is formed in the female head 4, a connecting plate is welded to the driving member, and a bolt is engaged with a nut after passing through the through hole and the connecting plate, thereby fixing the female head 4 and the driving member.
It should be noted that the driving member is a member that directly performs a linear motion. For cylinders and cylinders, the drive member is a piston; for an electric push rod, the driver is a push rod.
The female head 4 and the male head 2 need to be aligned with each other to complete the plugging action. However, since the female head 4 is moved by the linear driving module, the female head 4 may be rotated due to vibration or the like. Once the female head 4 deflects, the female head 4 and the male head 2 cannot be plugged.
For this reason, in the present embodiment, the linear driving module may be provided with a rotation prevention portion for preventing the female head 4 from rotating.
The rotation prevention part may include a linear rod, and the linear rod may be fixedly disposed on a housing of the linear driving module. Wherein, the female head 4 is provided with a sliding hole corresponding to the linear rod, and the linear rod is inserted into the sliding hole and is connected with the sliding hole in a sliding way. The linear rods are parallel to the linear motion direction of the female head 4, at least two linear rods are arranged, and the sliding holes correspond to the linear rods one to one.
The linear rod and the sliding hole can be in clearance fit. Wherein, can select suitable fit tolerance as required, avoid appearing the too big condition in clearance.
Except for the anti-rotation part, the anti-rotation cylinder can be adopted to avoid the deflection of the female head 4 in consideration of the influence of factors such as cost, assembly and the like.
Because the female head 4 is fixedly arranged on the driving piece, and the piston of the anti-rotation cylinder only can stretch out and draw back but not can rotate, the female head 4 can only do linear motion under the action of the piston.
Before the electric permanent magnetic chuck 1 is electrified, a user can observe whether the female head 4 is combined with or separated from the male head 2 by naked eyes.
In order to reduce the work intensity of the user, it is possible to detect whether the female head 4 is coupled to or separated from the male head 2 by providing a position sensor. The position of the female head 4 is detected using a position sensor, thereby detecting whether the female head 4 is coupled to or separated from the male head 2.
The position sensor may be a proximity switch or a hall sensor.
The position sensor may be connected to the controller and the indicator light. When the female head 4 is combined with the male head 2, the controller controls the indicator light to light; after the female head 4 is separated from the male head 2, the controller controls the indicator lamp to be turned off.
The magnetic attraction device for the machine tool provided by the embodiment realizes plug and play of power supply of the electric permanent magnetic chuck 1, and avoids the problems of short service life and inconvenient maintenance of a cable 3 caused by a direct wire outlet mode on the electric permanent magnetic chuck 1; the connector is plugged and pulled out by using the driving device 5, so that the connector is more efficient and safer, and the situations of electric shock and the like caused by manual operation are avoided.
In summary, the magnetic attraction device has the following advantages: the service life of the cable 3 is improved; the maintenance cost of the cable 3 is reduced; the safety of power utilization is improved.
In this embodiment, a machine tool is also proposed, comprising the above magnetic attraction device for a machine tool. Wherein the machine tool may comprise a lathe, a drilling machine, a grinding machine, a milling machine, a multi-axis milling machine, and the like.
