Description

Technical Field

[0001] The invention relates to the field of electromagnet assembly, and in particular to an installation device and an installation method for a nut and a wire clamp ring of an electromagnet. Background Art

[0002] As the core control component of the electro-hydraulic valve, the electromagnet has a harsh working environment, so in order to ensure its high reliability, the technical requirements for design are also very strict. Especially in terms of size, appearance and corrosion resistance. Among the parts that make up the electromagnet, the stator assembly process requires the rear end cover, coil, static iron core, junction box seat, junction box cover, aviation socket, nut and wire retaining ring for hole to be accurately installed according to the drawings.

[0003] Since the clamping force is difficult to control accurately, manual operation often cannot maintain balance and uniformity, which can easily cause scratches on the nut, static iron core and housing surface, thus affecting the appearance quality and performance of the product. In addition, manual operation may also lead to insufficient installation accuracy, unable to meet the design requirements, and thus affecting the working effect and reliability of the electromagnet.

[0004] The installation process of nuts and wire retaining rings for holes is still carried out manually, which is not only inefficient but also has many hidden dangers. The specific process is to manually press the nut into the wire retaining ring perpendicular to the direction of the nut using a press, and then use a tool to push the wire retaining ring into the annular groove inside the nut. In the above process, since the size of the pressing force is difficult to accurately control, manual operation often cannot maintain balance and uniformity. Too high a clamping force may cause scratches on the nut, static iron core or housing surface, affecting the product's appearance quality and corrosion resistance; too low a clamping force may cause the wire retaining ring to fail to be firmly fixed in the nut annular groove, causing assembly loosening or failure, reducing the reliability and service life of the electromagnet. Summary of the invention

[0005] In view of the problems mentioned in the prior art, the present invention proposes an installation device and an installation method for nuts and wire retaining rings for electromagnets, which solves the problems that when installing nuts and wire retaining rings for holes, the clamping force is difficult to control, the balance and uniformity cannot be controlled by manual operation, the appearance of the nuts, the static iron core and the casing are easily scratched, and the design accuracy and effect cannot be achieved.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: The present invention discloses an installation device for a nut and a wire clamp ring of an electromagnet, comprising a base plate and a bracket connected to the base plate, wherein a receiving space for installing a stator is provided in the bracket, a wire clamp ring is provided on the top of the stator, pushing members are connected at both ends of the bracket, and a nut is connected to the top of the bracket, and the wire clamp ring with a reduced outer diameter is pressed into the nut by the pushing member to complete the installation of the nut and the wire clamp ring.

[0007] As a further improvement of the present invention, threaded holes for the pushing member to pass through are radially provided at both ends of the bracket.

[0008] As a further improvement of the present invention, the pushing member includes a connected top screw and a push rod, wherein the push rod is in contact with the wire clamp ring.

[0009] As a further improvement of the present invention, open grooves for the push rod to pass through are provided at both ends of the nut.

[0010] As a further improvement of the present invention, it also includes a pad, which is arranged between the stator and the wire clamp ring, wherein the pad includes a first pad and a second pad.

[0011] As a further improvement of the present invention, a through hole is provided on the top of the bracket for the nut to pass through.

[0012] As a further improvement of the present invention, the base plate is detachably connected to the bracket via screws.

[0013] A method for installing a nut and a wire clamp for an electromagnet, comprising the following steps: Install the stator into the accommodation space of the bracket, connect the bracket to the bottom plate, insert the wire clamp and the first pad into the static iron core at the upper end of the stator, and install the nut on the top of the bracket to complete the preparation work; Pass the pusher through the threaded hole and hold the wire clamp ring. Rotate the pusher so that the pusher pushes the outer diameter of the wire clamp ring to reduce. Use a manual press to press the nut vertically downward. Under the action of the first pad, the wire clamp ring will be pushed into the entrance of the inner hole of the nut. Remove the bracket and the bottom plate, replace the second pad, and continue to press the nut with the manual press until the wire clamp ring is pushed into the annular groove inside the nut under the action of the second pad to complete the installation.

[0014] As a further improvement of the present invention, the pushing member compresses the outer diameter of the wire clamp to be no larger than the inner hole diameter of the nut.

[0015] As a further improvement of the present invention, the pushers are rotated alternately to distribute the outer diameter of the compressed wire clamp.

[0016] Compared with the prior art, the present invention has achieved the following technical effects: The present invention fixes the stator by means of a bracket and a bottom plate, and stably compresses the outer diameter of the wire clamp ring by means of the cooperation of a push rod and a top screw. The whole process not only ensures that the appearance of each component is not scratched, but also reduces the uncertainty caused by manual operation.

[0017] The backing plate provided in the present invention can push the wire clamp ring into the nut smoothly and accurately, which not only optimizes the installation process, but also improves the convenience and efficiency of operation, making the entire installation process smoother.

[0018] Compared with the traditional installation method, the method of the present invention not only reduces the difficulty of operation for workers, but also improves the installation efficiency and accuracy; it also solves the problem that the size of the clamping force in the traditional method is often difficult to accurately grasp, which can easily scratch the nut, the static iron core and the appearance of the casing, and also makes the installation accuracy and effect unable to meet the design requirements. The present invention improves the appearance qualification rate of the electromagnet, making the product more in line with the design requirements, and also significantly improves the corrosion resistance of the product and extends its service life.

[0030] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, the present invention is an installation device for nuts and wire clamps of electromagnets, comprising a base plate 3 and a bracket 2 connected to the base plate 3, wherein a receiving space 6 for installing a stator is opened in the bracket 2, a wire clamp 8 is provided on the top of the stator, pushing members are connected to both ends of the bracket 2, and a nut 4 is connected to the top of the bracket 2. The wire clamp 8 with a reduced outer diameter is pressed into the nut 4 by the pushing member to complete the installation of the nut 4 and the wire clamp 8.

[0032] Figure 1 As shown, the bracket 2 in the embodiment is cylindrical, and the cylindrical shape can usually provide stable support and is easy to match with a circular or annular stator. A accommodating space 6 is opened in the bracket 2, and the accommodating space 6 extends to the surface of the bracket 2 to form an opening, and the opening can expose the components on the stator. The opening in this embodiment is used to expose the mounting groove on the stator; the size, height and diameter of the accommodating space 6 in the embodiment are matched with the size of the stator, so that the stator can enter the accommodating space 6 and fit with the bracket 2, avoiding the stator from shaking or shifting in the bracket 2, thereby realizing the installation of the bracket 2 and the stator.

[0033] The bottom plate 3 in the embodiment is detachably connected to the bottom of the bracket 2. The embodiment preferably uses screws to connect the bracket 2 and the bottom plate 3, but is not limited to this. Other parts can also be used for connection as long as the connection can be achieved. The specific size of the bottom plate 3 is greater than or equal to the cross-sectional area of ​​the stator, so that the stator can be stably placed on the bottom plate 3. At the same time, the size of the bottom plate 3 is adapted to the size of the accommodating space 6, so that the bracket 2 and the bottom plate 3 can be connected to achieve fixed installation of the stator, effectively preventing the stator from shaking or shifting in the bracket 2.

[0034] The two ends of the bracket 2 are radially provided with threaded holes 9 for the pusher to pass through. The pusher comprises a connected top screw 1 and a push rod 5, wherein the push rod 5 is in contact with a wire clamp 8. Figure 2 As shown, the bracket 2 is provided with a pair of threaded holes 9 along the radial direction, the threaded holes 9 are respectively provided at both ends of the bracket 2, and internal threads are provided in the threaded holes 9 along the hole diameter direction; this embodiment provides a pushing member, and the wire retaining ring is compressed by rotating the pushing member.

[0035] The pushing member includes a push rod 5 and a top screw 1, wherein the top screw 1 is provided with an external thread on the outside, and the external thread matches the internal thread in the threaded hole 9. A through hole is provided at the bottom of the threaded hole 9 for the push rod 5 to penetrate. The push rod 5 contacts the outer surface of the wire retaining ring. The push rod 5 is connected to the top screw 1 and transmits the thrust generated by the top screw 1. The two are preferably connected in a fixed connection manner, but are not limited to this. Other connection methods can also be used according to actual needs. In the embodiment, the external thread of the top screw 1 needs to match the internal thread in the threaded hole 9 to avoid loosening due to thread mismatch.

[0036] When in use, the push rod 5 is inserted into the threaded hole 9 and passes through the threaded hole 9 to contact the wire clamp ring 8. By rotating the top screw 1, it can be moved forward or backward in the threaded hole 9. When the top screw 1 moves forward, the push rod 5 will move accordingly and compress the wire clamp ring 8 to achieve compression of the outer diameter of the wire clamp ring 8; the entire adjustment process can be carried out by rotating the two top screws 1 at the same time, or by rotating one top screw 1 first and then rotating the other top screw 1 to achieve distributed adjustment of the outer diameter of the wire clamp ring 8. The two adjustment methods are selected according to specific usage needs and usage scenarios to meet a variety of different usage scenarios.

[0037] The two ends of the nut 4 are provided with opening slots 10 for the push rod 5 to pass through. The top of the bracket 2 is provided with a through hole for the nut 4 to pass through. Figure 3 As shown, the nut 4 is hollow inside and is provided with an annular groove, the position of the annular groove is the position where the wire clamp 8 is installed, and the nut 4 is provided with open grooves 10 at both ends along the radial direction, and the open grooves 10 are provided to allow the push rod 5 to pass through the nut 4, so as to contact the wire clamp 8. The wire clamp 8 is compressed by the movement of the push rod 5. In the embodiment, the size of the open groove 10 is not limited, as long as the push rod 5 can pass smoothly.

[0038] In the embodiment, the inner hole of the nut 4 (indicating the size of the opening groove 10) is used to fix the wire clamp 8. The size of the inner hole needs to match the wire clamp 8 after the outer diameter is reduced. The wire clamp 8 is compressed to adapt to the size of the inner hole of the nut 4 through the pusher; a through hole is opened on the top of the bracket 2, and the through hole is used to install the nut 4. The size of the through hole matches the size of the nut 4, so that the nut 4 can be installed on the stator through the through hole.

[0039] It also includes a backing plate, which is arranged between the stator and the wire clamp ring 8. Figure 3 and Figure 4 As shown, the gasket in the embodiment includes a first gasket 7 and a second gasket 11 with different structures; the first gasket 7 includes a pair of semi-arc plates, so that the first gasket 7 can fit tightly on both sides of the wire clamp 8 to provide stable support for it. The design of the semi-arc plates can also ensure that when the press presses the nut 4, the first gasket 7 can evenly distribute the pressure and press the wire clamp 8 to be flush with the lower end surface of the nut 4.

[0040] like Figure 4 As shown, the second pad 11 is also a semi-arc structure, the difference being that a boss is provided in the middle of the second pad 11, the size of the boss matches the open groove 10 on the nut 4, and the size of the boss matches the open groove 10 on the nut 4; this structural design enables the boss to be accurately inserted into the open groove 10 when the nut 4 is placed on the second pad 11, and the cooperation ensures that the subsequent manual press has a fulcrum when pushing the wire clamp 8, and can effectively push the wire clamp 8 into the inner hole of the nut 4.

[0041] The installation method provided by the present invention first installs the stator into the accommodating space 6 of the bracket 2, and connects the bracket 2 with the bottom plate 3 to fix the stator; inserts the steel wire clamp 8 and the first pad 7 into the static iron core at the upper end of the stator, and installs the nut 4 on the bracket 2 through the through hole at the top of the bracket 2, and completes the preparation work; When in use, pass the push rod 5 through the threaded hole 9 and support the wire clamp ring 8, rotate the top screw 1 connected to the push rod 5, and then gradually screw the top screw 1 at least 1 to 1.2 turns simultaneously or with equal amplitude (no more than half a turn). At this time, the outer diameter of the wire clamp ring 8 should be compressed from 24.5mm to 22mm. Since there is a first pad 7 at the bottom of the wire clamp ring 8, at this time, use a manual press to press the nut 4 vertically downward, and the wire clamp ring 8 will be pushed into the entrance of the inner hole of the nut 4 by the pad. At this time, the wire clamp ring 8 is flush with the lower end surface of the nut 4.

[0042] Unscrew the top screw 1 and take out the push rod 5, remove the bracket 2 and the base plate 3, replace the first pad 7 with the second pad 11, so that the boss in the middle of the second pad 11 is inserted into the open groove 10 on the nut 4, and use a manual press to push the wire clamp 8 into the annular groove inside the nut 4 under the action of the boss, remove the second pad 11 and take out the stator, and complete the installation of the nut 4 and the wire clamp 8.

[0043] When the present invention is actually applied, according to the main economic indicators, sampling comparison is made before and after the installation of the wire clamp using this method, and 10 pieces are sampled and inspected each time. The appearance problems caused by the installation of nuts and wire clamps are greatly reduced, the operation difficulty of workers is also greatly reduced, and the production efficiency is greatly improved. The appearance qualification rate of the electromagnet is greatly improved, thereby improving the corrosion resistance of the product.

[0044] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
