Description

Technical Field

[0001] This invention relates to the field of adaptive floating positioning device technology, and more particularly to an adaptive floating positioning device for irregularly shaped magnetic components. Background Technology

[0002] Irregularly shaped magnetic components (such as irregular permanent magnets, customized magnetic cores, and magnetic composite components) are increasingly used in motors, sensors, precision instruments, medical equipment, and high-end consumer electronics due to their unique magnetic properties and geometries. The performance of these components in the final product largely depends on the accuracy and stability of their relative position with surrounding parts. Therefore, a device capable of precise and reliable positioning and fixation is needed during production, testing, or assembly.

[0003] Based on the specific shape of the component, a rigid positioning groove or gripper is machined to match it. This method is applicable to standard-shaped components, but for irregularly shaped parts, the processing cost is high and the versatility is extremely poor. Even slight batch differences in component dimensions or the presence of burrs or flash can easily lead to inaccurate positioning, excessive clamping stress, or even damage to the component. This is especially true for some irregularly shaped magnetic components with through holes in the center. During assembly, a positioning shaft is inserted to the center of the magnetic component, and then lowered to match the center point of the corresponding shaft cylinder and pressed down to achieve assembly. However, many high-performance magnetic materials, such as neodymium iron boron, ferrite, and certain magnetic cores, are highly hard but brittle and extremely sensitive to local stress concentration. When the position of the corresponding magnetic component and the positioning groove deviates, rigid clamping or point contact can easily cause micro-cracks or even breakage, directly affecting product life and performance. Therefore, an adaptive floating positioning device for irregularly shaped magnetic components is needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adaptive floating positioning device for irregularly shaped magnetic components includes an assembly disk, a four-way adjustment component at the bottom of the assembly disk, and an omnidirectional offset portion at the bottom of the four-way adjustment component. The four-way adjustment component includes a lateral offset portion and a longitudinal offset portion; The longitudinal offset portion includes a longitudinal rail plate. A slide rail B is movably installed on the top of the longitudinal rail plate through a rail groove. The top of the slide rail B is fixedly connected to the lower bearing block. Slider B is embedded in the left and right sides of the longitudinal rail plate through rail grooves and fixed with screws. A side plate B is connected to the top of the slider B. An elastic element B is installed through a threaded hole on the surface of the side plate B. The omnidirectional offset part includes a docking plate, which is fixedly connected to the bottom end face of the longitudinal rail plate. A docking cylinder is connected to the center of the bottom end of the docking plate. A positioning shaft is inserted into the bottom end of the docking cylinder through a threaded hole. The positioning shaft passes through the interior of the pressure plate through a central through hole. Several rubber pillars are arranged around the top of the pressure plate. The top of the rubber pillars is fixedly connected to the docking plate. When the positioning shaft is inserted into the central through hole of the irregular magnetic element, the bottom end of the positioning shaft protrudes into the interior of the irregular magnetic element. When the positioning shaft contacts the side of the cylindrical groove of the positioning groove, the positioning shaft can drive the lateral offset part and the longitudinal offset part to move through the docking plate due to the influence of the arc surface of the bottom end of the positioning shaft. This causes the positioning shaft to move laterally or longitudinally, so that the positioning shaft can adaptively insert into the cylindrical groove and carry the irregular magnetic element to match and assemble with the positioning groove. After the positioning shaft has finished working and moved upward, the positioning shaft is positioned by the return spring and the spring element built into the elastic element A.

[0006] Preferably, the bottom end of the positioning shaft has a curved structure, and the surface of the positioning shaft is surrounded by several vertical rubber plate ends. Several inverted triangular protrusion ends are equidistantly arranged on the surface of the rubber plate ends. Several through grooves are equidistantly opened on the side of the rubber plate ends of the positioning shaft. When the positioning shaft carrying the irregular magnetic element is embedded in the positioning groove and assembled with another element, the piston rod end of the cylinder pushes the movable ring. The movable ring pushes the ejector ring to move through the connecting shaft, so that the ejector ring can remove the irregular magnetic element from the surface of the positioning shaft, preventing the irregular magnetic element from being pulled out of the positioning groove when the positioning shaft moves upward.

[0007] Preferably, the surface of the assembly plate is covered with a rubber sleeve, which covers the lateral offset part, the longitudinal offset part and the omnidirectional offset part. The bottom edge of the rubber sleeve is inclined inward. The rubber sleeve plays a protective role, and the cavity inside the rubber sleeve can accommodate the movement of the lateral offset part, the longitudinal offset part and the omnidirectional offset part.

[0008] Preferably, the elastic element B includes a threaded rod inserted into the threaded hole of the side plate B. A return spring is connected to the inner end of the threaded rod. One end of the return spring is inserted with a pin through a through hole. The inner end face of the pin is fixedly connected to the inner end face of the shaft cylinder through the return spring. The stepped inner groove of the rubber sleeve can adapt to shaft cylinders of multiple diameters, so that the rubber sleeve can fit and wrap the shaft cylinder. The threaded rod and the side plate B are connected by a thread, which can facilitate the disassembly and replacement of the elastic element B as a whole. The return spring pushes the pin, which can drive the pin to abut against the end of the lower bearing block, thereby quickly resetting and positioning the lower bearing block.

[0009] Preferably, a rubber sleeve is fitted on the shaft end surface of the threaded rod, one side of the rubber sleeve abuts against the inner end face of the side plate B, and a stepped inner groove is formed on the inner wall of the rubber sleeve facing the shaft cylinder.

[0010] Preferably, a threaded adjusting pin B is inserted through a threaded hole at a position where the surface of the side plate B is flush with the elastic element B. By rotating and moving the threaded adjusting pin B in the threaded hole of the side plate B, the distance between the threaded adjusting pin B and the lower bearing block can be changed, thereby limiting the maximum moving distance of the slide rail B.

[0011] Preferably, the longitudinal rail plate has a material ejection part on its side. The material ejection part includes a cylinder movably installed on the side of the longitudinal rail plate. The piston rod end of the cylinder is fixedly connected to a movable ring. The movable ring is sleeved on the outside of the docking cylinder. Two connecting shafts are symmetrically arranged at the bottom end of the movable ring. The bottom end of the connecting shaft passes through the pressure plate through a movable hole and is fixedly connected to the material ejection ring.

[0012] Preferably, the two ends of the rubber column are configured as spherical structures, and the outer end of the spherical structure is provided with a flange end. The flange ends of the rubber column are fixed to the inner end faces of the mating plate and the pressure plate respectively by screws. The spherical end and the flange mating face are in contact, which avoids the stress concentration of rubber caused by sharp edge contact, greatly delays the process of rubber cracking or breaking due to fatigue. The flange provides a large bearing area, which can evenly transmit the pressure from the equipment structure to the end face of the entire rubber column and prevent local overload.

[0013] Preferably, the lateral offset portion includes a horizontal rail plate fixedly connected to the lower support block. A slide rail A is movably mounted on the top of the horizontal rail plate via a rail groove. An upper support block is connected to the top of the slide rail A. The top of the upper support block is fixed to the assembly plate via bolts. Slider A is symmetrically arranged on the left and right sides of the horizontal rail plate. A side plate A is connected to the top of the slider A. The slider A is fixed to the side of the horizontal rail plate by screws. An elastic element A and a threaded adjusting pin A are inserted into the same horizontal position through threaded holes on the surface of the side plate A. Guide shafts are connected to the left and right sides of the bottom end of the horizontal rail plate. The guide shafts are inserted into the side of the pressure plate through limiting grooves. The elastic element A has the same structure as the elastic element B.

[0014] This invention has at least the following beneficial effects: This invention, by setting up a four-way adjustment component consisting of a lateral offset part and a longitudinal offset part, and a universal offset part supported by multiple rubber pillars, enables the positioning shaft to have adaptive floating capability in the X, Y planes and angles. When there is a deviation between the bottom end of the positioning shaft and the positioning groove of the part to be assembled, the device can automatically perform lateral and longitudinal fine adjustments and slight tilting to guide the positioning shaft to be accurately inserted. This effectively solves the problem of assembly difficulties caused by batch differences in size or the presence of burrs in irregularly shaped parts, and significantly improves the versatility of the device and the assembly success rate.

[0015] This invention uses elastic elements A and B to provide the restoring force, and drives the ejector pin through a return spring for flexible contact and positioning, avoiding rigid impact. The curved structure at the bottom of the positioning shaft, the rubber plate end on the surface, and the inverted triangular protrusion design increase the contact flexibility and disperse the insertion stress. The spherical end face of the rubber column and the flange design avoid stress concentration, so that the force acting on the irregular magnetic element during positioning and assembly is gentle and uniform, which greatly reduces the risk of micro-cracks or breakage of the element due to local stress concentration, and protects the product performance and life.

[0016] After assembly, this invention can use a cylinder to move the ejector ring downwards via the movable ring and connecting shaft, smoothly ejecting the irregularly shaped magnetic component fitted on the positioning shaft and keeping it securely in the assembly position. This achieves an automatic ejection function, preventing the component from being carried out when the positioning shaft moves upwards, ensuring the continuity and reliability of the assembly process, facilitating integration with automated production lines, and improving overall assembly efficiency.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] Reference Figure 1-8 An adaptive floating positioning device for irregularly shaped magnetic components includes an assembly disk 1, a four-way adjustment component at the bottom of the assembly disk 1, and an omnidirectional offset part 4 at the bottom of the four-way adjustment component. The four-way adjustment component includes a lateral offset part 2 and a longitudinal offset part 3. The longitudinal offset part 3 includes a longitudinal rail plate 31. A slide rail B36 is movably installed on the top of the longitudinal rail plate 31 through a rail groove, and the top of the slide rail B36 is connected and fixed to the lower bearing block 37. Slider B32 is embedded on the left and right sides of the longitudinal rail plate 31 through rail grooves and fixed with screws. The top of the slider B32 is connected to a side plate B33, and an elastic element B34 is installed through a threaded hole on the surface of the side plate B33. The omnidirectional offset part 4 includes a docking plate 41, which is connected and fixed to the bottom end face of the longitudinal rail plate 31. A docking cylinder 42 is connected to the center of the bottom end of the docking plate 41, and a positioning shaft 44 is inserted into the bottom end of the docking cylinder 42 through a threaded hole. The positioning shaft 44 passes through the interior of the pressure plate 43 through the central through hole. Several rubber columns 45 for omnidirectional tilt deformation support are arranged around the top of the pressure plate 43, and the top of the rubber columns 45 is connected and fixed to the docking plate 41.

[0022] The bottom end of the positioning shaft 44 has a curved structure design, and several vertical rubber plate ends are arranged around the surface of the positioning shaft 44. Several inverted triangular protrusion ends are arranged at equal intervals on the surface of the rubber plate ends, and several through grooves are opened at equal intervals on the side of the rubber plate ends of the positioning shaft 44.

[0023] The surface of the assembly tray 1 is covered with a rubber sleeve 6, which covers the lateral offset part 2, the longitudinal offset part 3, and the omnidirectional offset part 4. The bottom edge of the rubber sleeve 6 is inclined inward.

[0024] The elastic element B34 includes a threaded rod 341 inserted into a threaded hole in the side plate B33, and a return spring 344 is connected to the inner end of the threaded rod 341. One end of the return spring 344 is inserted into a through hole and a pin 343 is inserted therein. The inner end face of the pin 343 is connected and fixed to the inner end face of the shaft cylinder 342 through the return spring 344.

[0025] A rubber sleeve 345 is fitted on the end surface of the threaded rod 341, and one side of the rubber sleeve 345 abuts against the inner end face of the side plate B33. A stepped inner groove is opened on the inner wall of the rubber sleeve 345 facing the shaft cylinder 342.

[0026] A threaded adjusting pin B35 is inserted through a threaded hole at the position where the surface of the side plate B33 is flush with the elastic element B34.

[0027] The longitudinal rail plate 31 is provided with a material ejection part 5 for material ejection. The material ejection part 5 includes a cylinder 51 movably installed on the side of the longitudinal rail plate 31. The piston rod end of the cylinder 51 is connected and fixed to the movable ring 52. The movable ring 52 is sleeved on the outside of the docking cylinder 42. Two connecting shafts 53 are symmetrically arranged at the bottom end of the movable ring 52. The bottom end of the connecting shaft 53 passes through the movable hole through the pressure plate 43 and is connected and fixed to the material ejection ring 54.

[0028] The rubber column 45 has spherical structures at both ends, and flange ends are provided on the outer ends of the spheres. The flange ends of the rubber column 45 are fixed to the inner end faces of the mating plate 41 and the pressure plate 43 respectively by screws.

[0029] The lateral offset part 2 includes a horizontal rail plate 21 that is connected and fixed to the lower support block 37. A slide rail A26 is movably installed on the top of the horizontal rail plate 21 through a rail groove, and an upper support block 27 is connected to the top of the slide rail A26. The top of the upper support block 27 is fixed to the assembly plate 1 by bolts. Slider A22 is symmetrically arranged on the left and right sides of the horizontal rail plate 21, and a side plate A23 is connected to the top of the slider A22. The slider A22 is fixed to the side of the horizontal rail plate 21 by screws. An elastic element A24 and a threaded adjusting pin A25 are inserted into the same horizontal position through threaded holes on the surface of the side plate A23. The elastic element A24 and the elastic element B34 have the same structure. Guide shafts 28 are connected to the left and right sides of the bottom of the horizontal rail plate 21, and the guide shafts 28 are inserted into the side of the pressure plate 43 through limiting grooves.

[0030] The curved structure design at the bottom of the positioning shaft 44 allows for easy adaptive adjustment of offset under pressure. The inverted triangular protrusion on the outer side of the positioning shaft 44 can be easily inserted into the central through hole of the irregular magnetic element, preventing the irregular magnetic element from easily detaching.

[0031] The rubber sleeve 6 forms a physical barrier, effectively preventing contaminants such as dust, chips, and liquids from the external environment from entering the precision moving parts and elastic components. This avoids wear, jamming, corrosion, or performance degradation caused by these contaminants, ensuring the long-term reliability and service life of the device in complex industrial environments. The inward-converging slope structure at the bottom of the rubber sleeve 6 provides a larger, interference-free space for the most exposed moving parts, especially the universal floating pressure plate 43 and its connected positioning shaft 44. This ensures that the edge of the pressure plate 43 will not rub or collide with the bottom of the rubber sleeve 6 when it is tilting adaptively. Furthermore, the inclined edge forms a flexible, non-right-angle contact boundary, which can buffer and guide even when there is slight contact with the workpiece or equipment table, reducing the risk of hard impacts.

[0032] When the lower support block 37 slides, forcing the ejector pin 343 to compress into the shaft cylinder 342, the return spring 344 is compressed and stores energy. When the external driving force decreases or disappears, the return spring 344 releases its potential energy, pushing the ejector pin 343 outward, thereby pushing the lower support block 37 in contact with it back to its initial position. By rotating the threaded rod 341 to change its depth in the side plate B33, the magnitude and point of application of the return force can be easily adjusted, achieving fine-tuning of the return performance and adapting to the needs of different working conditions. The stepped inner groove of the rubber pad 345 can adapt to shaft cylinders 342 of multiple diameters, allowing the rubber pad 345 to fit and wrap the shaft cylinder 342. The threaded rod 341 and the side plate B33 are connected by threads, which facilitates the disassembly and replacement of the elastic element B34 as a whole.

[0033] By rotating the threaded adjusting pin B35, the depth of its screw insertion can be precisely controlled, thereby changing the gap between its tip and the side surface of the lower support block 37. When the longitudinal offset part 3 is working, the lower support block 37 drives the slide rail B36 to slide along the longitudinal rail plate 31. If it slides in a certain direction, its movement stroke will be forcibly terminated when the side of the lower support block 37 contacts the tip of the threaded adjusting pin B35 in that direction. By adjusting the threaded adjusting pins B35 on both sides respectively, the maximum allowable floating stroke of the lower support block 37 in the positive and negative Y-axis directions can be set independently. The elastic element B34 provides a continuous elastic force to return the lower support block 37 to the center position, while the threaded adjusting pins B35 set the boundary of its movement from both sides. This design of elastic centering plus rigid boundary not only ensures the adaptive floating capability of the device within the allowable range, but also prevents the moving parts from overtraveling, derailing or colliding with the surrounding structure due to accidental overload or extreme deviation, ensuring the safety and reliability of the mechanism.

[0034] When the positioning shaft 44 carries the irregular magnetic element and is embedded in the positioning groove to assemble with another element, the piston rod end of the cylinder 51 pushes the movable ring 52. The movable ring 52 pushes the ejector ring 54 to move through the connecting shaft 53, so that the ejector ring 54 can remove the irregular magnetic element from the surface of the positioning shaft 44, preventing the irregular magnetic element from being pulled out of the positioning groove when the positioning shaft 44 moves upward. The movable hole of the pressure plate 43 is larger than the connecting shaft 53, providing room for the pressure plate 43 to tilt. This allows the pressure plate 43 to easily offset in all directions when under pressure, so that the pressure plate 43 can adapt to the tilted top surface of individual irregular magnetic elements.

[0035] The spherical end face meets the flange mating face, avoiding stress concentration in the rubber caused by sharp edge contact, greatly delaying the process of rubber cracking or breaking due to fatigue. The flange provides a large bearing area, which can evenly transmit the pressure from the equipment structure to the end face of the entire rubber column 45, preventing local overload.

[0036] The guide shaft 28 is rigidly connected to the horizontal rail plate 21, and its lower end is inserted into the limiting groove on the edge of the pressure plate 43. This limiting groove is not a tight-fitting hole, but has a larger movement space than the diameter of the guide shaft 28. It is an elongated hole or a similar structure. Its function is to realize the transmission and decoupling of motion. The guide shaft 28 has a vertical and a certain angular movement margin in the "limiting groove", so as not to restrict or interfere with the tilting movement of the pressure plate 43, thus ensuring the independence of planar floating and angular floating.

[0037] Working principle: During operation, the external drive mechanism moves the entire device downward through the assembly plate 1, so that the positioning shaft 44 is inserted into the center hole of the irregular magnetic element to be assembled and carries the element. As it continues to move, the bottom end of the positioning shaft 44 approaches or contacts the positioning groove of the target assembly.

[0038] If there is a planar position deviation, the curved surface at the bottom of the positioning shaft 44 will be subjected to a lateral force. This force is transmitted through the pressure plate 43 and the docking plate 41, driving the slide rail of the lateral offset part 2 or the longitudinal offset part 3 to overcome the elastic force of the corresponding elastic element A24 and elastic element B34 to slide, thereby realizing automatic alignment compensation in the X and Y directions.

[0039] If the surface of the irregularly shaped component is tilted, there will be an angular deviation when it is pressed down. The lateral force will cause the pressure plate 43 to compress the rubber column 45 on one side and tilt, thus achieving angle self-adaptation. Finally, the positioning shaft 44 can smoothly and accurately guide the magnetic component into the positioning groove to complete the assembly. After assembly, the device is lifted, and the cylinder 51 of the unloading part 5 is activated, pushing the piston rod end of the cylinder 51, which in turn drives the movable ring 52 and the connecting shaft 53 to move down in sequence, so that the connecting shaft 53 drives the unloading ring 54 to move down. Then the irregularly shaped magnetic component is pressed down, driving the irregularly shaped magnetic component to detach from the surface of the positioning shaft 44. When the positioning shaft 44 has moved up and detached from the positioning groove, under the action of the restoring force of the elastic element A24, the elastic element B34 and the rubber column 45, the lateral offset part 2, the longitudinal offset part 3 and the omnidirectional offset part 4 all return to their initial state, ready for the next operation.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
