Abstract
Description
Technical Field
[0001] The utility model belongs to the field of electromagnetic expansion technology, and in particular relates to a clamp adjustment structure based on electromagnetic technology. Background Art
[0002] Electromagnetic technology is to pass direct current into the electromagnet coil, generate a magnetic field around the coil, put an iron core into it, and according to the magnetic circuit theory, the magnetic flux gathers at the iron core, the magnetic field distribution is changed, and a strong magnetic force is exhibited near the iron core. This is an electromagnet, which has the property of attracting iron. The existing round tube clamping adopts pneumatic method, and the pneumatic clamp uses air pressure as the power source. When the air pressure enters the pneumatic clamp system, the sudden change in air pressure pushes the piston rod on the clamp to move. After a series of complex mechanical structures, the clamping parts clamp the workpiece to achieve clamping and positioning of the workpiece. When the air pressure is adjusted, the moving distance of the piston rod will also change, thereby achieving adjustable clamping of the workpiece, etc. Electromagnetic technology can be used in the use of clamping round tubes.
[0003] The existing technology has the following problems:
[0004] 1. The existing technology for clamping iron pipes on the market currently uses a pneumatic clamping mechanism, and the clamping force is provided by an air source. The pneumatic clamp has a complex structure, and some clamps are equipped with a lever mechanism to increase the clamping force. If the processing is unqualified, it may cause the lever to get stuck or the activity to become blocked, resulting in a short service life. Utility Model Content
[0005] The purpose of the utility model is to provide a clamp adjustment structure based on electromagnetic technology for existing devices to solve the problems raised in the above background technology.
[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a clamp adjustment structure based on electromagnetic technology, comprising an iron core, wherein a coil is sleeved and clamped on the outer ring surface of the iron core.
[0007] A steel pipe is placed on the upper surface of the iron core, and a protective shell is arranged on the upper surface of the iron core.
[0008] The side surface of the protective shell is fixedly connected with parallel clamping blocks.
[0009] The utility model further illustrates that a mounting opening is provided on the inner ring surface of the coil, and the mounting opening and the iron core are structurally matched with each other.
[0010] By adopting the above technical solution, the installation opening in the solution that matches the structure between the iron cores can facilitate the user to sleeve the coil on the iron core and then use the two iron cores in parallel for limited use.
[0011] The present utility model is further described as follows. On the other side surface of the protective shell, there are provided juxtaposed clamping openings, and the structures between the juxtaposed clamping openings and the juxtaposed clamping blocks are mutually adapted.
[0012] Adopting the above technical solution, the juxtaposed clamping openings whose structures are mutually adapted to the juxtaposed clamping blocks in this solution can facilitate the user to perform juxtaposed installation and clamping of the protective shell after clamping the juxtaposed clamping blocks into the juxtaposed clamping openings.
[0013] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:
[0014] The present utility model provides a fixture adjustment structure based on electromagnetic technology. Through the mutual cooperation and use of the provided iron core, coil, installation opening, steel pipe, protective shell, juxtaposed clamping block, and juxtaposed clamping opening, it can facilitate the user to perform electromagnetic clamping. Among them: The DC electromagnet is a device that works based on the principle of electromagnetic induction. When a DC current passes through the exciting coil, a magnetic field with a fixed magnitude and direction will be generated. This magnetic field causes the iron core and the steel pipe to generate magnetic force, resulting in the steel pipe being attracted or pushed. During the uniform forward movement of the steel pipe, a direct current is passed through the electromagnet coil fixed on the device, and the iron core is magnetized. When the user needs to clamp, the electromagnet needs to be energized, and the iron core is magnetized to generate suction force. When it needs to be released, the electromagnet is de-energized, and the magnetism of the iron core disappears. The greater the current and the more turns of the energized coil, the stronger the magnetic field. The magnetic lines of force generated by the energized coil form a closed loop through the iron core, air gap, and steel pipe of the electromagnet. Due to the contraction effect of the magnetic lines of force, an electromagnetic suction force is generated, causing the steel pipe to move in the axial direction of the iron core. Eventually, the steel pipe is relatively stationary with respect to the electromagnetic mechanism. According to Maxwell's formula and the full current theorem, the magnetic force F of the electromagnet on the iron pipe is positively correlated with the magnitude I of the passing current, the number of turns N of the coil, and the area S of the electromagnet, and negatively correlated with the air gap. When designing the electromagnet, appropriate N and S are determined to adapt to a larger suction force range. When the user places the electromagnet and the steel pipe, a relatively short distance is selected to reduce the air gap length and increase the suction force. In this way, the user can perform electromagnetic technology clamping on the steel pipe, meeting the user's need for electromagnetic technology clamping. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following further non-restrictive detailed description of the technical solution of the present utility model is given in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.
[0027] Please refer to Figures 1-9 , the present utility model provides a technical solution: A fixture adjustment structure based on electromagnetic technology, including an iron core 1, with a coil 2 sleeved and clamped on the outer surface of the iron core 1, and a steel pipe 4 placed in a limited position on the upper surface of the iron core 1.
[0028] In this embodiment, an installation opening 3 is provided on the inner surface of the coil 2, and the structure between the installation opening 3 and the iron core 1 is mutually compatible. The installation opening 3 that is mutually compatible with the iron core 1 can facilitate the user to limit and connect two iron cores 1 in parallel after sleeving the coil 2 on the iron core 1.
[0029] Embodiment 2
[0030] As Figures 1-9 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a protective shell 5 is provided on the upper surface of the iron core 1, and a parallel clamping block 6 is fixedly connected to the side surface of the protective shell 5.
[0031] In this embodiment, a juxtaposed clamping opening 7 is formed on the other surface of the protective shell 5, and the structures between the juxtaposed clamping opening 7 and the juxtaposed clamping block 6 are mutually compatible. The juxtaposed clamping opening 7 with a structure mutually compatible with the juxtaposed clamping block 6 in this solution can facilitate the user to juxtaposedly install and clamp the protective shell 5 after clamping the juxtaposed clamping block 6 into the juxtaposed clamping opening 7.
[0032] As Figures 1-9 shown, when the user needs to use it, among them: the DC electromagnet is a device that works based on the principle of electromagnetic induction. When a DC current passes through the exciting coil 8, a magnetic field with a fixed size and direction will be generated. This magnetic field causes the iron core 7 and the steel pipe 17 to generate magnetic force, resulting in the steel pipe 17 being attracted or pushed. During the uniform forward movement of the steel pipe 17, direct current is passed through the electromagnet coil 8 fixed on the device, and the iron core 7 is magnetized. When the user needs to clamp, the electromagnet needs to be energized, and the iron core 7 is magnetized to generate suction force. When it needs to be released, the electromagnet is powered off, and the magnetism of the iron core 7 disappears. The greater the current and the more turns of the energized coil 8, the stronger the magnetic field. The magnetic lines of force generated by the energized coil 8 form a closed loop through the iron core 7, air gap, and steel pipe 17 of the electromagnet. Due to the contraction effect of the magnetic lines of force, an electromagnetic suction force is generated, causing the steel pipe 17 to move in the axial direction of the iron core 7. Eventually, the steel pipe 17 is relatively stationary with the electromagnetic mechanism. According to Maxwell's formula and the law of total current, the magnetic force F of the electromagnet on the iron pipe is positively correlated with the magnitude I of the current passed, the number of turns N of the coil 8, and the area S of the electromagnet, and negatively correlated with the air gap. When designing the electromagnet, appropriate N and S are determined to adapt to a larger suction force range. When the user places the electromagnet and the steel pipe 17, a relatively short distance is selected to reduce the air gap length and increase the suction force. In this way, the user can clamp and use the steel pipe 17 with electromagnetic technology.

[0034] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features, and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
