Description

Technical Field

[0001] The present invention relates to the technical field of soft magnetic stainless steel processing, and specifically to a soft magnetic stainless steel bar and its processing equipment. Background Art

[0002] A telescopic electromagnet can control the generation and disappearance of a magnetic field by supplying power to and cutting off power from its excitation coil, so that a magnet located at the moving end extends out of or retracts into the electromagnet. By using this telescopic characteristic, functions such as effectively pushing an external object can be realized.

[0003] However, in actual production, considering costs and movement requirements, the moving part of a general telescopic electromagnet is generally composed of a basic connection part and an extended connection part. Among them, the basic connection part uses a material with strong magnetism to facilitate cooperation with the excitation coil to generate the power of movement, and the extended connection part uses a non-magnetic or soft magnetic material to achieve the pushing effect. Of course, if the extended connection part is made of soft magnetic material, functions such as magnetic separation can also be realized.

[0004] In the patent with the authorization announcement number CN204537791U and the patent name of telescopic electromagnet, a telescopic electromagnet is provided. The basic connection part of this electromagnet uses an iron rod, while the extended connection part uses a copper rod or a stainless steel rod. This patent mainly solves the problem that the connection between the basic connection part and the extended connection part in a traditional telescopic electromagnet mainly uses adhesive installation, resulting in insecure connection. However, in this patent, only the connection method is changed to riveting, which is still inconvenient for disassembly. Therefore, it is difficult to meet the existing requirements for connecting these two parts, and at the same time, there is a lack of equipment for efficiently and precisely processing the extended connection part.

[0005] Therefore, we need a soft magnetic stainless steel bar and its processing equipment to solve the problems in the prior art that there is a lack of a firm connection for the soft magnetic stainless steel bar located in the telescopic electromagnet and the soft magnetic stainless steel bar cannot be efficiently and highly precisely processed, which can effectively improve the production quality and use convenience of the soft magnetic stainless steel bar.

[0037] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0038] Example 1: Please refer to Figures 1 to 3, the present invention provides a soft magnetic stainless steel bar, including a soft magnetic stainless steel bar 3. The soft magnetic stainless steel bar 3 includes a main bar body 305 inserted into an iron bar 11. A first shoulder 301 is provided at the front end of the main bar body 305. A second shoulder 302 for limiting the end of the iron bar 11 is provided on the main bar body 305. A socket groove 306 is provided at the end of the main bar body 305. An anti-rotation protrusion 12 that is inserted into the socket groove 306 and used to prevent the main bar body 305 from rotating is provided inside the iron bar 11. An anti-detachment groove 307 is formed at the end of the main bar body 305. An elastic positioning protrusion 13 for clamping the anti-detachment groove 307 and preventing the main bar body 305 from falling off is installed inside the iron bar 11. The main bar body 305 is clamped with the iron bar 11 through a limiting device 7. A pair of guiding holes 303 are formed on the main bar body 305. The limiting device 7 includes a pair of sliding blocks 702 slidably installed in the guiding holes 303. A limiting protrusion 701 inserted into the inner wall of the iron bar 11 is integrally formed at the end of the sliding block 702. The two sliding blocks 702 are connected by a tightening spring 704. A limiting groove 304 for restricting the movement position of the limiting protrusion 701 is formed on the main bar body 305. A mating inclined surface 703 is integrally formed on the inner side of the sliding block 702. A central screw 10 is screwed and installed on the main bar body 305. The end of the central screw 10 presses on the mating inclined surface 703 to adjust the clamping state of the limiting protrusion 701.

[0039] Please refer to the patent with the authorization announcement number CN204537791 and the patent name of telescopic electromagnet. The iron bar 11 mentioned in this embodiment has the same function as the iron bar in this patent. The soft magnetic stainless steel bar 3 mentioned in this embodiment has the same function as the stainless steel bar in this patent. The difference is that the soft magnetic stainless steel bar 3 provided by the present invention itself can also be magnetized by the excitation coil inside the electromagnet, so that it can magnetically adsorb external objects after extending out of the electromagnet, such as pushing other objects by magnetism or performing magnetic separation on magnetic impurities, etc. After the excitation coil stops exciting, the soft magnetic stainless steel bar 3 provided by the present invention loses its magnetism and will retract into the electromagnet under the drive of the iron bar 11 to stop working. The soft magnetic stainless steel bar 3 provided in the present invention can be made of stainless steel of models such as 430F stainless steel, 405 stainless steel or 403 stainless steel. During the production process, a longer soft magnetic stainless steel bar can be first stretched and then cut to form a suitable soft magnetic stainless steel bar 3, and then processed into a finished soft magnetic stainless steel bar 3 through corresponding processing equipment.

[0040] When it is necessary to install the soft magnetic stainless steel rod 3 and the iron rod 11, first install the two sliding blocks 702 from the outside of the main rod body 305 into the guiding holes 303, and connect the two sliding blocks 702 by using the tightening spring 704, so that the two limiting protrusions 701 can enter the limiting grooves 304. Then insert the main rod body 305 into the iron rod 11 at the correct angle, and make the insertion slots 306 and the anti-rotation protrusions 12 be correctly slidably installed. Then, when it is felt that the elastic positioning protrusion 13 is snapped into the anti-disengagement groove 307 and the main rod body 305 cannot move forward any further, it means that the insertion is in place. Then correctly screw the central screw 10 into the soft magnetic stainless steel rod 3. At this time, the end of the central screw 10 can be used to squeeze the mating inclined surface 703, so that the limiting protrusion 701 is squeezed out of the limiting groove 304 and stuck on the inner wall of the iron rod 11, thus realizing the correct fixation of the soft magnetic stainless steel rod 3 and the iron rod 11. When it is necessary to disassemble the soft magnetic stainless steel rod 3 and the iron rod 11, only need to unscrew the central screw 10. At this time, the limiting protrusion 701 can retract into the limiting groove 304 under the drive of the tightening spring 704. Then, pull the soft magnetic stainless steel rod 3 outwards with force. At this time, the elastic positioning protrusion 13 deforms under the push of a lateral force exceeding its own bearing capacity, and thus slides out of the anti-disengagement groove 307, so that the soft magnetic stainless steel rod 3 can be pulled out. Therefore, the soft magnetic stainless steel rod 3 provided in this embodiment can realize quick fixation and disassembly. It solves the problem in the prior art of lacking a firm connection for the soft magnetic stainless steel rod located in the telescopic electromagnet, and can effectively improve the convenience of use of the soft magnetic stainless steel rod.

When it is necessary to move and adjust the soft magnetic stainless steel bar 3 along the guiding and connecting seat 23 at different processing positions through the workpiece adjusting device 2, the second moving seat 207 can be driven by the second lead screw motor 24 to move along the guide rail 8. Subsequently, the height of the lifting table 205 is adjusted by using the second lifting push rod 209, and the position of the supporting seat 204 is adjusted by using the horizontal push rod 206. Then, the inclination angle of the soft magnetic stainless steel bar 3 clamped by the clamping device 4 is adjusted by the rotating motor 201.

[0043] Please refer to Figure 4 , Figure 6 , Figure 7 and Figure 8, a workpiece clamping device 9 is respectively arranged at the working positions of the machine base 18 corresponding to the lathe 16, the drilling machine 15 and the tapping machine 14.

A clamping plate 904 for clamping the soft magnetic stainless steel rod 3 is driven at the end of the clamping push rod 903. When at least two clamping plates 904 move together towards the central axis of the connecting rod 901, the soft magnetic stainless steel rod 3 can be clamped and kept coaxial with the central axis of the connecting rod 901, so as to realize the precise positioning of the soft magnetic stainless steel rod 3, thus facilitating the subsequent processing of the soft magnetic stainless steel rod 3 by the lathe 16, the drilling machine 15 and the tapping machine 14. A position adjusting device 1 is arranged below the machine base 18 corresponding to each workpiece clamping device 9. The position adjusting device 1 includes a mounting seat 104 fixed on the machine base 18 by bolts, and a first lead screw motor 102 is fixedly installed on the mounting seat 104.

When it is necessary to adjust the position of the workpiece clamping device 9 to better fix the soft magnetic stainless steel rod 3 at a specified position, the first lead screw motor 102 can be used to drive the first moving seat 103 to move along the mounting seat 104, so as to control the distance between the soft magnetic stainless steel rod 3 and the lathe 16, the drilling machine 15 or the tapping machine 14. And the bearing frame 19 can be pushed to lift through the first lifting push rod 101, so as to accurately adjust the height of the soft magnetic stainless steel rod 3, so that the soft magnetic stainless steel rod 3 can be accurately fixed at the specified position, thus facilitating the precise processing of the soft magnetic stainless steel rod 3 by the lathe 16, the drilling machine 15 and the tapping machine 14. The connecting rod 901 and the bearing frame 19 are rotatably installed through bearings, and a gear ring 902 is concentrically fixed on the connecting rod 901.

When it is necessary to clamp the soft magnetic stainless steel rod 3 by using the clamping device 4, first, the tightening push rod 402 is used to open the distance between the first chuck 401 and the second chuck 403 to a specified distance. Subsequently, the operator rotates the adjusting rod 501 according to the size model of the soft magnetic stainless steel rod 3 to be processed, so that the pressing block 502 moves to a specified position by the push of the adjusting rod 501. Since the adjusting rod 501 is threadedly connected to the second chuck 403, only the number of turns of the adjusting rod 501 screwed into the second chuck 403 needs to be controlled to accurately control the position of the pressing block 502. Then, the corresponding model of the soft magnetic stainless steel rod 3 is placed between the first chuck 401 and the second chuck 403, and then the tightening push rod 402 can be used to tighten the distance between the first chuck 401 and the second chuck 403 to a specified distance. At this time, the soft magnetic stainless steel rod 3 can be firmly fixed by the first chuck 401 and the pressing block 502. When it is not necessary to change the model of the soft magnetic stainless steel rod 3 to be processed during subsequent processing, it is no longer necessary to readjust the position of the pressing block 502 until it is necessary to process soft magnetic stainless steel rods 3 of other models and then the position of the pressing block 502 needs to be readjusted.

[0046] In this embodiment, the soft magnetic stainless steel rod 3 can be clamped by the clamping device 4, and then the workpiece adjusting device 2 is used to transport and re-clamp the soft magnetic stainless steel rod 3 into the workpiece clamping device 9 at the corresponding position. Subsequently, the soft magnetic stainless steel rod 3 can be processed by the lathe 16, the drilling machine 15, or the tapping machine 14 at the corresponding position.

When it is necessary to clamp the soft magnetic stainless steel rod 3 by the clamping device 4, first, the first clamping block 401 and the second clamping block 403 are opened to a specified distance by tightening the push rod 402. Subsequently, the soft magnetic stainless steel rod 3 is manually placed on the docking support platform 203 and contacts the pressure detection sensor 202. When the pressure detection sensor 202 detects the corresponding pressure, the controller 17 can determine that the soft magnetic stainless steel rod 3 is placed in place. At this time, the controller 17 controls the tightening push rod 402 to tighten the first clamping block 401 and the second clamping block 403, so as to fix the soft magnetic stainless steel rod 3 by using the clamping device 4 and the extrusion block 502. Subsequently, the support base 204 is pushed outward by the horizontal push rod 206, so that the docking support platform 203 is separated from the support of the bottom of the soft magnetic stainless steel rod 3. At this time, there is no other structure at the bottom of the soft magnetic stainless steel rod 3 that will interfere with the rotation of the soft magnetic stainless steel rod 3. Then, the soft magnetic stainless steel rod 3 can be driven to rotate normally by the rotation motor 201. By adopting this method, the docking support platform 203 can be effectively used to position the soft magnetic stainless steel rod 3, so that the clamping device 4 can be correctly clamped to the specified position without the need for operators to adjust, thereby improving the clamping accuracy. At the same time, when adjusting the position of the soft magnetic stainless steel rod 3 in the horizontal direction, the docking support platform 203 can be separated from the bottom of the soft magnetic stainless steel rod 3 by the way, so as to avoid the docking support platform 203 interfering with the normal rotation of the soft magnetic stainless steel rod 3, further reducing the steps that need to be intervened by operators during the processing, improving the degree of automation, and thus improving the processing efficiency. Further solve the problem of the lack of high-efficiency and high-precision processing of soft magnetic stainless steel rods in the prior art, and can effectively improve the production quality of soft magnetic stainless steel rods.

[0048] Embodiment 4: Please refer to Figure 10 and Figure 12, on the basis of the third embodiment, a positioning detection device 6 for detecting whether the clamping device 4 has clamped the soft magnetic stainless steel rod 3 in place is provided on the clamping device 4. The positioning detection device 6 includes a second connecting block 609 fixedly installed on the first clamping block 401, and a plugging hole 608 is formed in the second connecting block 609. A first connecting block 603 for inserting into the plugging hole 608 is fixedly installed on the second clamping block 403. A sliding groove 607 for slidably installing a ball head rod 605 is formed in the first connecting block 603, and a return spring 606 is connected between the bottom of the sliding groove 607 and the ball head rod 605. An elastic piece 604 for restricting the movement position of the ball head rod 605 is fixedly installed at the end of the sliding groove 607. A matching groove 602 for clamping with the ball head part of the ball head rod 605 is formed in the plugging hole 608. A positioning switch 601 for detecting whether the ball head rod 605 enters the matching groove 602 is fixedly installed at the bottom of the matching groove 602, and the positioning switch 601 is electrically connected to the controller 17. When the first clamping block 401 and the second clamping block 403 do not enter the clamping state, at this time the first connecting block 603 also does not insert into the plugging hole 608. At this time, the ball head rod 605 will extend outwards under the extrusion of the return spring 606, but the ball head rod 605 will only extend the ball head part at the end out of the sliding groove 607 under the limit of the elastic piece 604. Subsequently, when the first clamping block 401 and the second clamping block 403 approach each other and enter the clamping position of the soft magnetic stainless steel rod 3, the first connecting block 603 will also enter the plugging hole 608. During the process of the first connecting block 603 entering the plugging hole 608, the top of the ball head rod 605 will be squeezed by the inner wall of the plugging hole 608 and thus temporarily retracted into the sliding groove 607. Subsequently, when the sliding groove 607 moves to a position aligned with the matching groove 602, the ball head rod 605 will enter the matching groove 602 under the extrusion of the return spring 606. At this time, the ball head rod 605 can be used to clamp the first connecting block 603 and the second connecting block 609, so as to avoid relative displacement caused by shaking or the like during the movement of the ends of the first clamping block 401 and the second clamping block 403, resulting in an error in the clamping of the soft magnetic stainless steel rod 3. Moreover, after the ball head rod 605 enters the matching groove 602, it will also squeeze the positioning switch 601 to trigger the positioning switch 601, so that the controller 17 can determine that the clamping device 4 has completed the clamping work on the soft magnetic stainless steel rod 3, and thus automatically enter the subsequent operation steps. Therefore, the use of the positioning detection device 6 can not only improve the clamping accuracy of the clamping device 4 for the soft magnetic stainless steel rod 3, but also reduce the operation steps of the operator, improve the automation degree of equipment production, and further solve the problem of the lack of efficient and high-precision processing of soft magnetic stainless steel rods in the prior art, and can effectively improve the production quality of soft magnetic stainless steel rods.

[0049] Embodiment 5: On the basis of Embodiment 4, the present invention further provides a usage method of a processing device for a soft magnetic stainless steel bar, including the following steps:

[0050] Step 1: First, use the second lead screw motor 24 to drive the workpiece adjusting device 2 to a preset loading and unloading position close to the controller 17. Subsequently, open the distance between the first clamping block 401 and the second clamping block 403 to a specified distance through the tightening push rod 402. Then, manually rotate the adjusting rod 501 according to the model of the soft magnetic stainless steel bar 3 to be produced to accurately push the extrusion block 502 to a specified position, thus completing the initialization adjustment of the device;

[0051] Step 2: Subsequently, the operator or the manipulator places the soft magnetic stainless steel bar 3 above the docking support table 203, and makes the soft magnetic stainless steel bar 3 located between the first clamping block 401 and the second clamping block 403 and pressed against the pressure detection sensor 202. At this time, the controller 17 will detect the signal that the soft magnetic stainless steel bar 3 has been in place through the pressure detection sensor 202. Subsequently, the controller 17 contracts the first clamping block 401 and the second clamping block 403 to the clamping position through the tightening push rod 402, thereby using the clamping device 4 and the adaptation adjusting device 5 to complete the clamping of the soft magnetic stainless steel bar 3;

[0052] Step 3: When the soft magnetic stainless steel bar 3 is correctly clamped by the clamping device 4, the controller 17 first uses the horizontal push rod 206 to push the support seat 204 to move. At this time, the docking support table 203 disengages from the bottom of the soft magnetic stainless steel bar 3. Subsequently, adjust the soft magnetic stainless steel bar 3 to a horizontal position through the rotation motor 201. At this time, the second lead screw motor 24 can be used to drive the second moving seat 207 to move to a position aligned with the workpiece clamping device 9 of the corresponding lathe 16. Subsequently, lift the soft magnetic stainless steel bar 3 to a position coaxial with the connecting rod 901 through the second lifting push rod 209 and wait for clamping replacement. When the soft magnetic stainless steel bar 3 is waiting for clamping replacement, at this time, the first lead screw motor 102 at the corresponding position will push the first moving seat 103 to move, so that the clamping plate 904 enters a position where it can correctly clamp the soft magnetic stainless steel bar 3. Then, use the clamping push rod 903 to drive the clamping plate 904 to clamp the soft magnetic stainless steel bar 3;

[0053] Step 4: After the workpiece clamping device 9 completes the clamping of the soft magnetic stainless steel bar 3, the second lead screw motor 24 will push the workpiece adjusting device 2 into a non-working position. Subsequently, the first lifting push rod 101 on the workpiece clamping device 9 will adjust the soft magnetic stainless steel bar 3 to a processing height adapted to the lathe 16, and then use the first lead screw motor 102 to send the soft magnetic stainless steel bar 3 into the processing area of the lathe 16, and then the lathe 16 can be used to complete the turning processing of the soft magnetic stainless steel bar 3, thereby cutting to form the first shoulder 301, the second shoulder 302, and the main rod body 305;

[0054] Step Five: After waiting for the turning process of the lathe 16 to be completed, the workpiece adjusting device 2 is driven again by the second lead screw motor 24 to a position corresponding to the workpiece clamping device 9. Then, the soft magnetic stainless steel rod 3 is re-clamped back to the clamping device 4. Next, the soft magnetic stainless steel rod 3 is pushed by the workpiece adjusting device 2 to the workpiece clamping device 9 corresponding to the drilling machine 15, and the soft magnetic stainless steel rod 3 is re-clamped to the workpiece clamping device 9 at this position. Subsequently, the workpiece clamping device 9 at this position and the drilling machine 15 are used to process the soft magnetic stainless steel rod 3, thereby machining the guiding hole 303, the limiting groove 304, and the hole for installing the center screw 10.

[0055] Step Six: After waiting for the processing of the drilling machine 15 to be completed, the workpiece adjusting device 2 is driven again by the second lead screw motor 24 to a position corresponding to the workpiece clamping device 9. Then, the soft magnetic stainless steel rod 3 is re-clamped back to the clamping device 4. Next, the soft magnetic stainless steel rod 3 is pushed by the workpiece adjusting device 2 to the workpiece clamping device 9 corresponding to the tapping machine 14, and the soft magnetic stainless steel rod 3 is re-clamped to the workpiece clamping device 9 at this position. Subsequently, a thread for screwing and installing the center screw 10 is machined at the main rod body 305 through the cooperation of the workpiece clamping device 9 at this position and the tapping machine 14. Then, the soft magnetic stainless steel rod 3 is re-clamped onto the clamping device 4 again. Then, the workpiece adjusting device 2 is driven by the second lead screw motor 24 to move back to the preset loading and unloading position near the controller 17. The clamping device 4 releases the processed soft magnetic stainless steel rod 3, and then the processed soft magnetic stainless steel rod 3 can be taken out manually or by a manipulator.
