Description

Technical Field

[0001] The utility model relates to the technical field of electromagnets, in particular to an automatic compensation device for electromagnet gaps. Background Art

[0002] An electromagnet is a device that generates electromagnetic fields when electricity is applied. It is a non-permanent magnet. The magnetic field it generates depends on the current, the number of coil turns, and the central ferromagnetic material. Therefore, when designing an electromagnet, attention should be paid to the layout of the coils and the selection of the ferromagnetic material, and the current should be used to control the magnetic field. Furthermore, electromagnets offer many advantages: their magnetism can be controlled by turning the current on and off; their magnetism can be controlled by the current strength or the number of coil turns; their magnetism can also be controlled by changing the resistance to control the current; and their magnetic poles can be controlled by changing the direction of the current. In other words, the strength of the magnetism can be altered, its presence can be controlled, the direction of the magnetic poles can be changed, and the magnetism can be eliminated by removing the current.

[0003] The applicant searched and obtained the following prior art. Specifically, patent publication number CN110171499A discloses a suction-type electromagnetic foot with a floating mechanism. This patent relates to robotics and addresses the prior art issue of a large gap between the robot foot and the suction surface, preventing reliable and stable suction on uneven surfaces. The suction-type electromagnetic foot with a floating mechanism comprises an electromagnetic foot body and an electromagnet assembly disposed at the base of the electromagnetic foot body. By providing a floating mechanism, the electromagnet automatically adjusts its suction posture on the target surface within a relatively small range, thereby compensating for the suction gap and effectively ensuring stable and reliable suction.

[0004] As can be seen from the above patent, although this adsorption-type electromagnetic foot with a floating device can compensate for the adsorption gap through the floating mechanism, it can effectively ensure that the adsorption-type electromagnetic foot is stably and reliably adsorbed. However, in actual use, since the floating mechanism is in the form of a spherical hinge, the electromagnet can only adjust the adsorption posture within a relatively fixed rotation range to compensate for the gap, and it is difficult to provide sufficient compensation spacing for the electromagnet. Not only does it make it impossible for the electromagnet to be firmly adsorbed to the surface of the target object, reducing the stability and reliability of the electromagnet adsorption, it also limits the adaptability of the electromagnet to different positions on the surface of the target object, reducing the adsorption effect on the target object. In addition, this spherically hinged floating mechanism makes it difficult to control the position and posture of the electromagnet during adsorption, and cannot ensure close fit with the surface of the target object, affecting the adsorption effect. Utility Model Content

[0005] The present application provides an automatic compensation device for the gap of an electromagnet to solve one of the following problems: 1. It is difficult to provide sufficient compensation spacing for the electromagnet, so that the electromagnet cannot be firmly adsorbed to the surface of the target object, reducing the stability and reliability of the electromagnet adsorption.

[0006] 2. It limits the adaptability of the electromagnet to different positions on the surface of the target object, reducing the adsorption effect on the target object.

[0007] 3. It is difficult to control the position and posture of the electromagnet during adsorption, and it is impossible to ensure close fit with the surface of the target object, which affects the adsorption effect.

[0008] To achieve the above-mentioned purpose, the technical solution adopted in this application is: an automatic compensation device for electromagnet gap includes a base, an electromagnet and an adjustment mechanism, the base is used to abut against the surface of the target object, the electromagnet is movably installed on the base and is used to magnetically fix the target object, the base is detachably installed at a preset position through the adjustment mechanism, and the adjustment mechanism is used to adjust the spatial position of the base and the electromagnet.

[0009] Preferably, the adjustment mechanism includes a base plate and several adjustment components for supporting the base, the base plate is detachably mounted to a preset position by a locking member, the several adjustment components are located between the base plate and the base, and the several adjustment components are evenly and spaced apart along the circumference of the base plate.

[0010] Preferably, through holes are opened on the base at positions corresponding to the several adjustment components, and the several adjustment components all include a sleeve, a first elastic member and a limit member. The sleeve is vertically arranged on the base plate and plugged into the through hole. The first elastic member is sleeved on the outer wall of the sleeve, and the limit member extends into the through hole and the sleeve is detachably connected.

[0015] Beneficial effects:

[0016] 1. The utility model provides an automatic electromagnet gap compensation device that can increase the distance between the base and the preset position through an adjustment mechanism, and thereby simultaneously reduce the distance between the electromagnet and the surface of the target object, thereby providing sufficient compensation distance for the electromagnet, enabling it to contact and firmly adsorb to the surface of the target object, thereby improving the stability and reliability of the electromagnet adsorption.

[0017] 2. The utility model provides an automatic compensation device for the gap of an electromagnet. The adjustment mechanism enables the base to adaptively tilt and swing, and thereby synchronously changes the position state of the electromagnet relative to the surface of the target object. That is, the electromagnet can adapt to the uneven position of the surface of the target object. At the same time, the base provides the electromagnet with sufficient compensation spacing to ensure that the electromagnet can stably adsorb to the surface of the target object after power is turned on, thereby improving the adaptability of the electromagnet to different positions on the surface of the target object and improving the adsorption effect on the target object.

[0032] Example 1:

[0033] The utility model provides an automatic compensation device for electromagnet gap.

[0034] In one embodiment of the present invention, an automatic electromagnet gap compensation device 100 includes a base 1, an electromagnet 2 and an adjustment mechanism, the base 1 is used to abut against the surface of a target object, the electromagnet 2 is movably mounted on the base 1 and is used to magnetically fix the target object, the base 1 is detachably mounted at a preset position through the adjustment mechanism, and the adjustment mechanism is used to adjust the spatial position of the base 1 and the electromagnet 2.

[0035] Working principle: The utility model is an automatic electromagnet gap compensation device 100 that adjusts the distance and horizontal or tilted position of the electromagnet 2 on the base 1 relative to the surface of the target object through an adjustment mechanism, thereby accurately controlling the position and posture of the electromagnet 2 during adsorption to ensure the adsorption and fixing effect of the target object.

[0036] Specifically, if Figures 2 to 5 As shown, since the electromagnet 2 is movably mounted on the base 1, the electromagnet 2 and the base 1 can be movably mounted in a manner of connection with an elastic member, through which the electromagnet 2 can rebound and move relative to the target object on the base 1, that is, after the electromagnet 2 is energized, it is adsorbed to the surface of the target object, thereby temporarily fixing the target object to the preset position of the base 1, and the elastic member is in a compressed state at this time; at the same time, when the electromagnet 2 is powered off, the elastic member rebounds, thereby causing the electromagnet 2 to separate from the surface of the target object, thereby releasing the magnetic attraction and fixation of the target object. At this time, the target object can move relative to the electromagnet 2, and the structural design is simple and reasonable.

[0037] Furthermore, since the base 1 is detachably mounted at a preset position through an adjusting mechanism, and the base 1 is used to abut against the surface of the target object (the base 1 can provide auxiliary support for the target weapon when abutting against the surface of the target object, and the target object is mainly supported by its own driving mechanism at the preset position), when there is a large gap between the electromagnet 2 and the surface of the target object, the distance between the base 1 and the preset position can be increased through the adjusting mechanism, and the distance between the electromagnet 2 and the surface of the target object can be simultaneously reduced, thereby providing sufficient compensation distance for the electromagnet 2, so that it can contact and firmly adsorb to the surface of the target object, thereby improving the stability and reliability of the adsorption of the electromagnet 2.

[0038] It can be understood that when the surface of the target object is uneven, the base 1 can adaptively tilt and swing under the action of the adjustment mechanism, and since the electromagnet 2 is always in contact with the base 1 under the action of the elastic member, the position state of the electromagnet 2 relative to the surface of the target object can be changed synchronously, that is, the electromagnet 2 can adapt to the uneven position of the target object surface, and at the same time, the base 1 provides the electromagnet 2 with sufficient compensation spacing to ensure that the electromagnet 2 can stably adsorb to the surface of the target object after power is turned on, thereby improving the adaptability of the electromagnet 2 to different positions on the surface of the target object and improving the adsorption effect on the target object; at the same time, the adjustment mechanism can also limit the position and posture of the base 1 when it is in contact with the surface of the target object, effectively preventing the base 1 and the electromagnet 2 from moving or shaking at will when they are in contact with the surface of the target object, ensuring that the base 1 can be in stable contact with the target object, so that the electromagnet 2 can fit tightly with the surface of the target object, thereby ensuring the adsorption effect of the electromagnet 2 on the target object and reliable use.

[0039] It is worth noting that if Figure 1 As shown, the present invention provides an automatic electromagnet gap compensation device 100 that can be applied to an X-ray bed (in this case, the preset position is the bed frame 201 of the X-ray bed, and the target object is the bed panel 202). Since the bed panel 202 of the X-ray bed needs to be moved and adjusted relative to the bed frame 201 along its length and width to facilitate the imaging of the subject on the bed panel 202, after the bed panel 202 is moved and adjusted into position, the present invention can magnetically fix the bed panel 202, effectively preventing the bed panel 202 from moving relative to the bed frame 201 during the imaging process, thereby ensuring the stability of the bed panel 202 during the imaging process. At the same time, since the bed panel 202 has a certain degree of flexibility during its production, its surface may be concave and uneven. The present invention uses an adjustment mechanism to enable the electromagnet 2 to adapt to the degree of concave at different positions of the bed panel 202, thereby ensuring the magnetic fixation effect of the bed panel 202.

[0040] In one embodiment, the adjustment mechanism includes a base plate 3 and a plurality of adjustment components 4 for supporting the base 1. The base plate 3 is detachably mounted to a preset position by a locking member. The plurality of adjustment components 4 are located between the base plate 3 and the base 1, and the plurality of adjustment components 4 are evenly and spaced apart along the circumference of the base plate 3. Specifically, Figure 2 and Figure 3 As shown, the removable mounting method of the base plate 3 and the preset position can adopt a threaded connection, thereby facilitating the disassembly and assembly of the base plate 3, the multiple adjustment components 4, and the base 1, and facilitating maintenance and replacement. Furthermore, because the multiple adjustment components 4 are evenly and spaced along the circumference of the base plate 3, they can provide support for the base 1 at multiple points. This not only ensures the auxiliary support effect of the base 1 on the target object, but also enables the base 1 to drive the electromagnet 2 to better adapt to the surface of the target object, resulting in a simple and reasonable structural design.

[0041] In one embodiment, through holes are provided on the base 1 at positions corresponding to the plurality of adjustment components 4. The plurality of adjustment components 4 each include a sleeve 5, a first elastic member 6, and a stopper 7. The sleeve 5 is vertically arranged on the base plate 3 and plugged into the through hole. The first elastic member 6 is sleeved on the outer wall of the sleeve 5. The stopper 7 extends into the through hole and is detachably connected to the sleeve 5. Specifically, Figures 2 to 5 As shown, the installation method of the sleeve 5 and the base plate 3 can be threaded, so that the sleeve 5, the first elastic member 6 and other components can be easily disassembled and replaced; at the same time, the first elastic member 6 can be a spring in the prior art, which has the characteristics of compact structure, easy material acquisition, and large elastic restoring force, so as to facilitate installation and drive the base 1 to move relative to the base plate 3, so as to better achieve the adaptive effect of the base 1 and the electromagnet 2 to the concave and convex position of the target object surface. Further, the limiter 7 can be a screw in the prior art, that is, the detachable connection method of the limiter 7 and the sleeve 5 is also threaded. Since the sleeve 5 is vertically arranged on the base plate 3 and the first elastic member 6 is sleeved on the outer wall of the sleeve 5, the staff can adjust the installation distance of the base 1 relative to the base plate 3 by screwing the limiter 7, thereby adjusting the distance between the electromagnet 2 and the target object surface, ensuring that sufficient compensation distance is provided for the electromagnet 2, so that the electromagnet 2 can be firmly adsorbed to the target object surface during use, and the structural design is simple and reasonable.

[0042] In one embodiment, if Figure 2 、 Figure 3 and Figure 5 As shown, the sleeve 5 and the base plate 3 are an integral structure. It can be understood that by making the sleeve 5 and the base plate 3 into an integral structure, the assembly step between the sleeve 5 and the base plate 3 can be omitted, the assembly gap is avoided, the assembly error is eliminated, and the manufacturing is easy.

[0043] In one embodiment, a telescopic rod 8 is detachably mounted on the electromagnet 2, a through hole for the telescopic rod 8 to pass through is provided on the base 1, a second elastic member 9 is sleeved on the telescopic rod 8, and one end of the second elastic member 9 is connected to the bottom surface of the base 1. Specifically, Figure 2 and Figure 3 As shown, the telescopic rod 8 can be a screw rod as known in the art, and the detachable mounting method of the telescopic rod 8 and the electromagnet 2 is also a threaded connection, thereby facilitating the disassembly and assembly of the electromagnet 2. Furthermore, since the telescopic rod 8 is provided with a second elastic member 9, the second elastic member 9 can also be a spring as known in the art. The spring has the characteristics of a large elastic restoring force. The elastic restoring force of the spring can drive the electromagnet 2 to move away from the target object when the power is not supplied, thereby maintaining a state of separation from the surface of the target object, preventing the electromagnet 2 from contacting the surface of the target object when the power is not supplied, and affecting the normal movement and adjustment of the target object, thereby ensuring reliable use.

[0044] In one embodiment, if Figure 3 As shown, the base 1 is provided with a plurality of positioning holes 10 at intervals, and the electromagnet 2 is provided with positioning posts 11 that plug into and engage with the positioning holes 10. Specifically, the plug-in engagement of the positioning posts 11 with the positioning holes 10 improves the smooth movement of the electromagnet 2 when it is attached to or detached from the target object, preventing the electromagnet 2 from moving freely on the base 1 and affecting the magnetic attraction and fixation effect on the target object.

[0045] In one embodiment, a plurality of balls 12 are detachably mounted on the base 1. The balls 12 are evenly and spaced apart along the circumference of the base 1, and the balls 12 are all used to abut against the surface of the target object. Figure 3 As shown, the base 1 and the target object can achieve rolling contact through a plurality of balls 12, thereby improving the smoothness of the movement of the target object; at the same time, since the plurality of balls 12 are evenly and spaced along the circumference of the base 1, the auxiliary support effect on the target object can be improved, and the structural design is ingenious and reasonable.

[0046] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
