Description

Technical Field

[0001] The invention belongs to the technical field of magnetic material cutting fixtures, and in particular relates to a magnetic material cutting fixture and a realization method thereof. Background Art

[0002] Magnetic materials are materials that can respond to magnetic fields in some way. According to the strength of the magnetism exhibited by the material in the external magnetic field, it can be divided into diamagnetic materials, paramagnetic materials, ferromagnetic materials, antiferromagnetic materials and ferrimagnetic materials. Most materials are diamagnetic or paramagnetic, and they react weakly to the external magnetic field. Ferromagnetic materials and ferrimagnetic materials are strong magnetic materials. The magnetic materials usually refer to strong magnetic materials. When producing magnetic materials, the materials need to be cut, so the clamps are needed.

[0003] The existing clamp is a fixed ring fixed on the cutting table. The fixed ring is formed by rotating two semicircular rings, and the other end is locked by a bolt. During use, the clamp needs to be manually operated each time a cutting action is completed, which has the problems of high labor intensity and low cutting efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a magnetic material cutting clamp to solve the problems mentioned in the above background technology. The magnetic material cutting clamp provided by the present invention has the characteristics that the clamp can be opened and closed quickly and automatically.

[0005] Another object of the present invention is to provide a method for implementing a clamp for cutting magnetic materials.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a clamp for cutting magnetic materials, comprising a base, chucks are respectively installed at the two ends above the base, and a pressing assembly is installed in the middle position of the base, the chuck comprises a chuck seat, a slider is slid on the chuck seat, a first spring is connected between the bottom of the slider and the base, racks are respectively connected on both sides of the slider, symmetrical jaws are installed on both sides of the chuck seat, a rotating part is provided at the end of the jaw, the rotating part is rotatably connected to the chuck seat, and a gear ring meshing with the rack is provided on the rotating part.

[0007] In order to guide the sliding of the slider and install the clamping claw, a sliding groove is further provided in the middle of the chuck seat, and installation grooves are respectively provided on both sides of the sliding groove on the chuck seat.

[0008] In order to drive the pressing block to move downward and drive the magnetic material to move downward, the pressing stroke can be accurately adjusted according to the diameter of the magnetic material to be cut, thereby ensuring the stability of the clamping of the magnetic material. Furthermore, the pressing assembly includes a mounting seat, on which a pressing electric cylinder is mounted, and a pressing block is connected to the output end of the pressing electric cylinder, and a pressing block arc groove is provided on the bottom surface of the pressing block.

[0009] In order to ensure that there is rolling friction between the magnetic material and the chuck when the magnetic material is fed forward, the friction force is smaller than that of sliding friction, which facilitates feeding and avoids scratching the surface of the magnetic material. Furthermore, a supporting wheel is installed at the upper end of the slider and a pressure wheel is installed on the inner side of the clamp.

[0010] In order to perform preliminary positioning of the magnetic material when placing the magnetic material and ensure the accuracy of the positioning of the magnetic material, further, a positioning arc groove is provided on the circumference of the supporting wheel.

[0011] In order to adjust the angle between the first clamp arm and the second clamp arm so as to be suitable for magnetic materials of different specifications, the clamp further includes a first clamp arm and a second clamp arm, wherein the first clamp arm is rotatably connected to the second clamp arm, and the first clamp arm and the second clamp arm are also connected by a limit member.

[0012] In order to limit the angle between the first clamp arm and the second clamp arm and ensure that the second clamp arm does not rotate during the clamping process, thereby ensuring the stability of the clamping, further, the limiting member includes a first meshing tooth, a second meshing tooth and a connecting bolt, wherein the first meshing tooth is arranged on the second clamp arm, the second meshing tooth is arranged on the first clamp arm, the first meshing tooth is meshed with the second meshing tooth, and the end of the connecting bolt passes through the first clamp arm and is meshed and connected with the second clamp arm.

[0013] In order to separate the first meshing teeth from the second meshing teeth when loosening the connecting bolt, thereby facilitating adjustment of the angle of the second clamping arm, further, a second spring is sleeved on the connecting bolt and the second spring is located between the first clamping arm and the second clamping arm.

[0014] In order to limit the maximum displacement stroke of the slider, the calibration position is positioned by cooperating with the through hole. On the one hand, the accuracy of the chuck calibration is guaranteed, and on the other hand, it is convenient to quickly calibrate the chuck when replacing magnetic materials of different specifications. Furthermore, the upper end of the slider is connected to the upper limit block, and the lower end of the slider is connected to the lower limit block. The slider is provided with a through hole close to the upper limit block, and a photoelectric device corresponding to the through hole is installed above the chuck seat.

[0015] In the present invention, the method for realizing the magnetic material cutting fixture further comprises the following steps:

[0016] (i) When using for the first time, first calibrate the chuck according to the diameter of the magnetic material, adjust the second clamp arm to be parallel to the first clamp arm, place the magnetic material on the support wheel, control the piezoelectric cylinder to press the magnetic material down to the calibration position, and then adjust the second clamp arm again to make the pressure wheel contact the magnetic material to complete the calibration of the chuck;

[0017] (ii) After the calibration is completed, the magnetic material is placed on the support wheel, and the downward pressure electric cylinder is started. The downward pressure electric cylinder presses the magnetic material down to the clamping position, and the two clamping claws cooperate with the support wheel to clamp and fix the magnetic material;

[0018] (3) When the magnetic material needs to be fed forward, the downward pressure electric cylinder drives the downward pressure block to move upward to the feeding position. At this time, the two clamps open. After the feeding of the magnetic material is completed, the downward pressure electric cylinder continues to drive the downward pressure block to the clamping position.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention controls the movement of the slider by pressing down the assembly and the first spring, and drives the two clamping jaws to open and close under the cooperation of the rack and the gear ring, thereby realizing the rapid clamping and releasing of the magnetic material without manual operation, which is more convenient to use, reduces labor intensity, and improves the cutting efficiency of the magnetic material;

[0021] 2. The present invention drives the lower pressing block to move downward through the lower pressing electric cylinder, thereby driving the magnetic material to move downward. The stroke of the lower pressing electric cylinder can be accurately adjusted according to the diameter of the magnetic material to be cut, thereby ensuring the stability of the clamping of the magnetic material;

[0022] 3. A support wheel is installed at the upper end of the slider of the present invention, and a pressure wheel is installed on the inner side of the clamping jaw. When the magnetic material is fed forward, there is rolling friction between the magnetic material and the clamping head. Compared with sliding friction, the friction force is smaller, which is convenient for feeding and can also avoid scratching the surface of the magnetic material.

[0023] 4. The supporting wheel of the present invention is provided with a positioning arc groove on its circumference, which can be used to perform preliminary positioning of the magnetic material when placing the magnetic material, thereby ensuring the accuracy of the positioning of the magnetic material;

[0024] 5. The clamping jaw of the present invention comprises a first clamping arm and a second clamping arm, wherein the first clamping arm is rotatably connected to the second clamping arm, and the first clamping arm and the second clamping arm are also connected by a limiter, so that the angle between the first clamping arm and the second clamping arm can be adjusted, so that it can be suitable for magnetic materials of different specifications;

[0025] 6. The present invention achieves the angle limitation between the first clamp arm and the second clamp arm by meshing the first meshing teeth with the second meshing teeth, ensuring that the second clamp arm will not rotate during the clamping process, thereby ensuring the stability of the clamping;

[0026] 7. The present invention limits the maximum displacement stroke of the slider by the cooperation of the upper limit block and the lower limit block, and realizes the positioning of the calibration position by the cooperation of the photoelectric projection and the through hole. On the one hand, it ensures the accuracy of the calibration of the chuck, and on the other hand, it is convenient to quickly calibrate the chuck when replacing magnetic materials of different specifications.

[0058] By adopting the above technical solution, the maximum displacement stroke of the slider 23 is limited by the cooperation of the upper limit block 231 and the lower limit block 233, and the calibration position is positioned by the cooperation of the reflected photoelectric 28 and the through hole 232. On the one hand, the accuracy of the calibration of the chuck 2 is guaranteed, and on the other hand, it is convenient to quickly calibrate the chuck 2 when replacing magnetic materials of different specifications.

[0059] Example 5

[0060] Furthermore, the method for implementing a magnetic material cutting fixture according to the present invention comprises the following steps:

[0061] (i) When using for the first time, first calibrate the chuck 2 according to the diameter of the magnetic material 4, adjust the second clamping arm 265 to be parallel to the first clamping arm 261, place the magnetic material 4 on the supporting wheel 25, and control the lower pressure electric cylinder 32 to press the magnetic material 4 down to the calibration position (assuming that the maximum displacement stroke of the slider 23 is X, the distance from the origin position of the lower pressure block 33 to the origin position of the slider 23 is L, and the diameter of the magnetic material 4 is D. During normal operation, the pressing stroke of the lower pressure electric cylinder 32 is L-D+X, and during calibration, the pressing stroke of the lower pressure electric cylinder 32 is L-D+X-2, in millimeters). When the reflected photoelectric 28 receives a signal, the lower pressure electric cylinder 32 stops moving, and then adjust the second clamping arm 265 again to make the pressure wheel 24 contact the magnetic material 4, thereby completing the calibration of the chuck 2;

[0062] (ii) After the calibration is completed, the magnetic material 4 is placed on the support wheel 25, and the downward pressure electric cylinder 32 is started. The downward pressure electric cylinder 32 presses the magnetic material 4 down to the clamping position (i.e., the downward pressure stroke is L-D+X), and the two clamping claws 26 cooperate with the support wheel 25 to clamp and fix the magnetic material;

[0063] (III) When the magnetic material 4 needs to be fed forward, the downward pressure electric cylinder 32 drives the downward pressure block 33 to move upward to the feeding position (i.e., drives the downward pressure block 33 to move upward 3-4 mm). At this time, the two clamping jaws 26 are opened. After the feeding of the magnetic material 4 is completed, the downward pressure electric cylinder 32 continues to drive the downward pressure block 33 to press down to the clamping position.

[0064] In summary, the present invention controls the movement of the slider 23 through the pressing assembly 3 and the first spring 22, and drives the two clamping jaws 26 to open and close under the cooperation of the rack 27 and the gear ring, thereby realizing the rapid clamping and releasing of the magnetic material 4, and no manual operation is required, which is more convenient to use, reduces labor intensity, and improves the cutting efficiency of the magnetic material; the present invention drives the lower pressing block 33 to move downward through the pressing electric cylinder 32, thereby driving the magnetic material 4 to move downward, and can accurately adjust the stroke of the pressing electric cylinder 32 according to the diameter of the magnetic material 4 to be cut, thereby ensuring the stability of the clamping of the magnetic material 4. The upper end of the slider 23 of the present invention is equipped with a supporting wheel 25, and the inner side of the clamping jaw 26 is equipped with a pressing wheel 24. When the magnetic material 4 is fed forward, there is rolling friction between the magnetic material 4 and the chuck 2. Compared with sliding friction, the friction force is smaller, which is convenient for feeding and can also avoid scratching the surface of the magnetic material 4; the circumference of the supporting wheel 25 of the present invention is provided with a positioning arc groove, which can be used to position the magnetic material 4 when placing the magnetic material 4. The magnetic material is preliminarily positioned to ensure the accuracy of the positioning of the magnetic material 4; the clamping jaw 26 of the present invention includes a first clamping arm 261 and a second clamping arm 265, wherein the first clamping arm 261 and the second clamping arm 265 are rotatably connected, and the first clamping arm 261 and the second clamping arm 265 are also connected by a limiter, so that the angle between the first clamping arm 261 and the second clamping arm 265 can be adjusted, so that it can be suitable for magnetic materials 4 of different specifications; the present invention realizes the limiting of the angle between the first clamping arm 261 and the second clamping arm 265 by meshing the first meshing tooth 264 with the second meshing tooth 266, ensuring that the second clamping arm 265 will not rotate during the clamping process, thereby ensuring the stability of the clamping; the present invention limits the maximum displacement stroke of the slider 23 by the upper limit block 231 and the lower limit block 233, and realizes the positioning of the calibration position by the matching photoelectric 28 and the through hole 232, on the one hand, ensuring the accuracy of the calibration of the clamp 2, on the other hand, facilitating the rapid calibration of the clamp 2 when replacing magnetic materials of different specifications.
