Description
Technical Field
[0001] This invention belongs to the field of clamp support technology, and specifically relates to an electromagnetic centerless support device. Background Technology
[0002] In the field of machining, electromagnetic centerless clamps are widely used in the machining of rotating parts such as shafts and sleeves due to their advantages of precise positioning and stable clamping. As the core component of electromagnetic centerless clamps, the performance of the support structure directly affects the machining accuracy and efficiency of the parts. The main function of the support structure is to provide auxiliary support for the machined parts, prevent the parts from deforming or shifting due to their own weight or cutting force during high-speed rotation machining, and ensure the stability of the machining process. In existing technologies, such as the support structure of an electromagnetic centerless clamp with patent number CN211540846U, the radial adjustment plate connected to the axial adjustment plate is often adjusted manually. Manual adjustment is inefficient, especially when batch processing parts of different specifications, requiring frequent manual adjustments to the support position, increasing operation time and reducing production efficiency. Furthermore, the floating support head, support roller, and radial adjustment plate are usually connected as a single unit. When the floating support head or support roller is worn or damaged, the entire floating support head, support roller, and connected radial adjustment plate need to be disassembled and replaced, which is cumbersome and increases costs. Therefore, an electromagnetic centerless support device is proposed to solve the above problems. Summary of the Invention
[0003] The purpose of this invention is to provide an electromagnetic centerless support device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: an electromagnetic centerless support device, comprising an adjustment seat disposed on an axial adjustment plate of an electromagnetic centerless clamp, wherein an installation groove is provided inside the adjustment seat, an electric push rod is fixedly installed on the inner wall of the installation groove, an adjustment plate is fixedly installed on the telescopic end of the electric push rod, a connecting plate is provided on one side of the adjustment plate, a support arm is hinged to the side of the connecting plate away from the adjustment plate, a floating support head is hinged to one side of the support arm, and a support roller is provided on the floating support head; A plug is fixedly installed on one side of the connecting plate. A slot adapted to the plug is opened inside the adjusting plate. A spring is fixedly installed inside the adjusting plate. A moving block is fixedly installed on one side of the spring. A limiting rod is fixedly passed through the moving block. A limiting groove adapted to the limiting rod is opened inside the plug. An anti-detachment component is provided on the adjusting seat.
[0005] With the above technical solution, starting the electric push rod can drive the adjustment plate to move smoothly, and then drive the floating support head and support roller to move synchronously through the connecting plate and support arm. No manual adjustment is required, which improves the operation efficiency. When it is necessary to repair or replace the floating support head and support roller, it is only necessary to control the movement of the limit rod. The limit rod drives the moving block to compress the spring and separate from the limit groove on the insert block. The connecting plate and the insert block can then be removed from the slot of the adjustment plate. The disassembly process is simple and convenient, effectively reducing the maintenance time.
[0006] In a preferred embodiment, one end of the limiting rod extends through the outside of the adjusting plate and is fixedly connected with a pull ring.
[0007] With the above technical solution, the operator can directly move the limit rod and the moving block by pulling the pull ring without the need for additional tools, which further simplifies the unlocking operation of the insertion block and improves the convenience of disassembling and installing the support components.
[0008] In a preferred embodiment, the anti-detachment component includes a fixing block, which is fixedly connected to the adjusting seat. A locking rod is fixedly installed on one side of the fixing block. The locking rod has a through groove adapted to the pull ring inside. When the adjusting plate is in the initial position, the through groove corresponds to the position of the pull ring.
[0009] The above technical solution achieves precise positioning and convenient operation of the limiting rod and pull ring. When the adjusting plate is in the initial position, the pull ring and the locking rod are aligned in the through slot. The operator can pull the pull ring directly through the through slot with their finger to complete the disassembly of the support component. When the device is in normal use, the electric push rod drives the adjusting plate to move, which in turn moves the pull ring upward to the top of the through slot. At this time, the locking rod can limit and block the pull ring, effectively preventing the limit rod from moving accidentally and causing the insert block to unlock, thereby preventing the floating support head and support roller from falling off and ensuring the stability of the device operation.
[0010] In a preferred embodiment, sliders are fixedly installed on both sides of the moving block, and the inside of the adjusting plate is provided with a groove that matches the slider.
[0011] Through the above technical solution, the sliding cooperation between the slider and the groove can accurately limit the movement trajectory of the moving block, avoid deviation when the moving block drives the limit rod to move, ensure that the limit rod can accurately insert into or disengage from the limit groove of the plug block, and ensure the reliable realization of the locking and unlocking functions.
[0012] In a preferred embodiment, the adjusting seat has a connecting groove inside.
[0013] The above technical solution allows for easy fixing of the adjusting seat using the connecting groove, improving the stability and convenience of the adjusting seat installation.
[0014] Compared with the prior art, the beneficial effects of the present invention are: This electromagnetic centerless support device enables precise electric adjustment, significantly improving operational efficiency and support stability. Compared to the manual adjustment method described in the previous paper, this device uses an electric push rod to drive the adjustment plate, which in turn moves the connecting plate, support arm, floating support head, and support roller synchronously. This eliminates the need for manual operation, allowing for precise adjustment of the support position, shortening the adjustment time for processing parts of different specifications, and improving production efficiency. At the same time, the hinged connection between the floating support head and the support arm allows the support roller to adaptively conform to the surface of the part to be processed, further ensuring support stability and helping to improve the processing accuracy of the parts. In normal use, the electric push rod drives the adjustment plate to move, and the pull ring moves to the top of the locking rod through the groove. The locking rod limits the pull ring to prevent the floating support head and support roller from falling off due to accidental movement of the limiting rod. This electromagnetic centerless support device allows for easy and convenient operation when the floating support head and support rollers detach for maintenance or replacement. An electric push rod resets the adjusting plate, and the operator can pull the ring through the through slot to disengage the limiting rod from the insert block's limiting slot. The connecting plate, along with the insert block, can then be directly removed from the adjusting plate's slot for maintenance or replacement of the floating support head and support rollers. This eliminates the need to remove the adjusting seat. Attached Figure Description

[0017] The present invention will be further described below with reference to embodiments.
[0018] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0019] Please see Figure 1-3The present invention provides an electromagnetic centerless support device, including an adjustment seat 1 disposed on an axial adjustment plate of an electromagnetic centerless clamp. The adjustment seat 1 has a connecting groove 15 inside, which can be used to easily fix the adjustment seat 1, thereby improving the stability and convenience of the installation of the adjustment seat 1.
[0020] Furthermore, the interior of the adjusting seat 1 is provided with an installation groove. An electric push rod 2 is fixedly installed on the inner wall of the installation groove inside the adjusting seat 1. An adjusting plate 3 is fixedly installed on the telescopic end of the electric push rod 2. A connecting plate 4 is provided on one side of the adjusting plate 3. A support arm 5 is hinged to the side of the connecting plate 4 away from the adjusting plate 3. A floating support head 6 is hinged to one side of the support arm 5. A support roller 7 is provided on the floating support head 6.
[0021] Furthermore, a plug block 8 is fixedly installed on one side of the connecting plate 4, and a slot adapted to the plug block 8 is opened inside the adjusting plate 3. A spring 9 is fixedly installed inside the adjusting plate 3, and a moving block 10 is fixedly installed on one side of the spring 9. A limiting rod 11 is fixedly passed through the moving block 10, and a limiting groove adapted to the limiting rod 11 is opened inside the plug block 8.
[0022] Furthermore, one end of the limiting rod 11 extends through the outside of the adjusting plate 3 and is fixedly connected to a pull ring 13. The operator can directly move the limiting rod 11 and the moving block 10 by pulling the pull ring 13 without the need for additional tools, which further simplifies the unlocking operation of the insert block 8 and improves the convenience of disassembly and installation of the support components. Slider blocks 14 are fixedly installed on both opposite sides of the moving block 10. The adjusting plate 3 has a sliding groove inside that matches the slider 14. The sliding cooperation between the slider 14 and the sliding groove can accurately limit the movement trajectory of the moving block 10, preventing the moving block 10 from deviating when it moves the limiting rod 11, ensuring that the limiting rod 11 can accurately insert into or disengage from the limiting groove of the insert block 8, and ensuring the reliable realization of the locking and unlocking functions.
[0023] Furthermore, the adjusting seat 1 is equipped with an anti-detachment component 12, which includes a fixing block 121. The fixing block 121 is fixedly connected to the adjusting seat 1. A locking rod 122 is fixedly installed on one side of the fixing block 121. The locking rod 122 has a through groove adapted to the pull ring 13. When the adjusting plate 3 is in the initial position, the through groove corresponds to the position of the pull ring 13. When the adjusting plate 3 is in the initial position, the pull ring 13 corresponds to the position of the through groove of the locking rod 122. The operator can put their finger through the through groove and pull the pull ring 13 directly to complete the disassembly operation of the support component. When the device is in normal use, the electric push rod 2 drives the adjusting plate 3 to move, which drives the pull ring 13 to move upward synchronously to the top of the through groove. At this time, the locking rod 122 can form a limit block on the pull ring 13, effectively preventing the limit rod 11 from moving accidentally and causing the insert block 8 to unlock, thereby preventing the floating support head 6 and the support roller 7 from falling off and ensuring the stability of the device operation.
[0024] The working principle of this invention is as follows: First, the basic installation and positioning of the device is completed by using the connecting groove 15 inside the adjusting seat 1, which ensures the stability of the adjusting seat 1 during subsequent work. When faced with workpieces of different diameters, the electric push rod 2 in the mounting slot of the adjusting seat 1 is activated. The telescopic end of the electric push rod 2 drives the adjusting plate 3 to move smoothly. The adjusting plate 3 drives the connecting plate 4 to move synchronously through the cooperation of the insert 8 and the slot. Then, the connecting plate 4 drives the support arm 5, the floating support head 6 and the support roller 7 to move synchronously until the support roller 7 reaches the support position that matches the workpiece to be processed, thus achieving precise electric adjustment without manual operation. When the device is in normal use, after the electric push rod 2 drives the adjustment plate 3 to move, the pull ring 13 on the adjustment plate 3 will move upward synchronously to the through slot of the locking rod 122. At this time, the locking rod 122 forms a limit block on the pull ring 13, avoiding the limit rod 11 and the pull ring 13 from moving accidentally due to factors such as vibration during device operation, thereby preventing the insertion block 8 from unlocking the slot of the adjustment plate 3, and ultimately ensuring that the floating support head 6 and the support roller 7 will not fall off, thus improving the safety of device operation. After use, the electric push rod 2 controls the adjustment plate 3 to retract and reset. When the floating support head 6 or support roller 7 needs to be inspected or replaced after use, the electric push rod 2 has already driven the adjusting plate 3 to return to its initial position. The pull ring 13 corresponds to the through slot of the locking rod 122. The operator can pull the pull ring 13 through the through slot. The pull ring 13 drives the limiting rod 11 and the moving block 10 to move synchronously. The moving block 10 compresses the spring 9 inside the adjusting plate 3. At the same time, the sliders 14 on both sides of the moving block 10 slide smoothly along the slide groove of the adjusting plate 3, ensuring that the limiting rod 11 accurately disengages from the limiting slot on the insert block 8. At this time, the insert block 8 is unlocked, and the connecting plate 4 together with the insert block 8 can be directly removed from the slot of the adjusting plate 3, thereby completing the inspection or replacement of the floating support head 6 and support roller 7 without removing the adjusting seat 1. The operation is simple and convenient.
