Description

Technical Field

[0001] The invention relates to the technical field of hole assembly structures, and in particular to a gap assembly structure between a thin wall and an acting body in a microwave integrated module. Background Art

[0002] In the assembly process of high-precision electronic products, various problems of the assembly of the actuator and the thin wall are involved. For example, in the microwave integrated module, a cylindrical thin wall is required as a shield or protective cover for the actuator. For this, the existing assembly process generally passes screws through the threaded holes on the thin wall and then fixes them on the actuator. The whole assembly process has high requirements on the process, and the three need to reach the best matching state. Otherwise, there will be an assembly gap, which will eventually cause the thin wall to deform and shorten its service life. For this purpose, there is a publication number of CN 212055403. U's Chinese utility model patent discloses a gap compensation structure, locking structure and assembly structure between a thin wall and an actuator to solve the above-mentioned problems. The gap is mainly controlled by setting a compensation structure between the thin wall and the actuator. However, for a cylindrical (most common) actuator, the thickness of the cylindrical thin wall is limited. In high-precision equipment, processing internal threads on such a thin wall will result in the following problems: first, the hardness of some thin walls does not meet the processing requirements; second, the thin walls may crack or be damaged; and third, the difficulty of thin-wall processing is increased, resulting in a longer process time. These points reduce the efficiency of high-precision processing and assembly. Summary of the invention

[0003] The object of the present invention is to provide a gap assembly structure between a thin wall and an acting body in a microwave integrated module, which can complete the assembly of the thin wall and the acting body without machining threaded holes on the thin wall.

[0004] An embodiment of the present invention is achieved through the following technical solutions: a gap assembly structure between a thin wall and an acting body in a microwave integrated module, comprising: a compensation sleeve, two wing ears are symmetrically arranged on the outer side of the compensation sleeve; the length of the compensation sleeve is greater than the gap between the thin wall and the acting body; the distance between the wing ear and one end of the compensation sleeve is smaller than the gap between the thin wall and the acting body; a locking bolt, which comprises a first screw and a second screw with diameters increasing successively and connected to each other; the first screw is provided with a first external thread; a through hole is provided on the thin wall for the compensation sleeve and the wing ear to pass through, and the longest inner diameter of the through hole is arranged perpendicular to the axis of the thin wall; a screw hole matching the first external thread is provided on the acting body; when the first screw moves toward the screw hole, the second screw drives the compensation sleeve to move in a direction away from the acting body.

[0005] Furthermore, the thin wall is provided with limiting holes on both sides of the through hole.

[0006] Furthermore, the second screw rod is provided with a second external thread, the inner side of the compensation sleeve is provided with an internal thread matched with the second external thread, and the second external thread and the first external thread are arranged in opposite directions of rotation.

[0007] Furthermore, a protrusion is provided on the outer side of the second screw rod, and a sliding groove is provided on the inner side of the compensation sleeve. The protrusion is slidably arranged in the sliding groove, and the sliding groove is extended along the axial diameter of the compensation sleeve.

[0008] Furthermore, an axial force bearing structure is provided at the end of the second screw.

[0009] Furthermore, in the microwave integrated module, at least three gap assembly structures between the thin wall and the acting body are provided in the same plane.

[0010] Furthermore, the through hole is elliptical; the diameter of the compensation sleeve is equal to the minimum inner diameter of the through hole.

[0011] The present invention has at least the following advantages and beneficial effects: by providing a compensation sleeve to abut the thin wall and the acting body from the gap, the thin wall is fixed relative to the acting body, avoiding the need to open a threaded hole on the thin wall; in addition, the entire installation process is simple and quick.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1

[0024] like Figure 2 As shown, in this embodiment, a gap assembly structure between a thin wall 2 and an acting body 1 is mainly disclosed, which mainly includes: a compensation sleeve 3 and a locking bolt 4. Specifically, the compensation sleeve 3 is a sleeve structure, and two wing ears 12 are symmetrically arranged on the outer side of the compensation sleeve 3. Preferably, one side of the wing ear 12 is arc-shaped and is arranged to fit the inner side of the thin wall 2. The connecting line of the two wing ears 12 is parallel to the axis of the thin wall 2, as shown in FIG. Figure 2 As shown, the two wing ears 12 fit the inner side of the thin wall 2 and can use the arc structure to close the thin wall 2 so that the wing ears 12 fix the distance between the thin wall 2 and the actuator 1; the length of the compensation sleeve 3 is greater than the gap between the thin wall 2 and the actuator 1. Specifically, as shown Figure 1As shown, one end of the compensation sleeve 3 needs to limit the sliding of the thin wall 2 in the axial direction; the distance between the wing ear 12 and one end of the compensation sleeve 3 is smaller than the gap between the thin wall 2 and the actuator 1, thereby ensuring that the wing ear 12 can be placed between the actuator 1 and the thin wall 2, thereby abutting the thin wall 2, and assembling the thin wall 2 relative to the actuator 1. Specifically, one end of the compensation sleeve 3 can be disassembled and fixed on the actuator 1, and the other end abuts against the inner side of the thin wall 2 through the wing ear 12 to complete the assembly between the thin wall 2 and the actuator 1.

[0025] The structure in which one end of the compensation sleeve 3 is detachably fixed to the actuator 1 is implemented by a locking bolt 4. Specifically, the locking bolt 4 includes a first screw rod 6 and a second screw rod 7 with increasing diameters and connected to each other; the first screw rod 6 is provided with a first external thread.

[0026] like Figure 3 As shown, the thin wall 2 is provided with a through hole 5 for the compensation sleeve 3 and the wing ear 12 to pass through, and the longest inner diameter of the through hole 5 is arranged perpendicular to the axis of the thin wall 2; preferably, the through hole 5 is an elliptical hole, the major axis of the ellipse is arranged perpendicular to the axis of the thin wall 2, and the minor axis of the ellipse is arranged parallel to the axis of the thin wall 2, as shown in FIG. Figure 4 As shown, the two wing ears 12 enter from the long axis of the through hole 5, and then rotate the wing ears 12 by 90 degrees, as shown in FIG. Figure 5 As shown, the wing ear 12 is abutted against the inner side of the thin wall 2 at the minor axis.

[0027] Specifically, since the distance between the wing ear 12 and one end of the compensation sleeve 3 is smaller than the gap between the thin wall 2 and the actuator 1; therefore, when the wing ear 12 abuts against the inner side of the thin wall 2, the gap between the compensation sleeve 3 and the actuator 1 needs to be compensated, specifically by the locking bolt 4, and the actuator 1 is provided with a screw hole 8 that matches the first external thread; when the first screw 6 moves toward the screw hole 8, the second screw 7 drives the compensation sleeve 3 to move away from the actuator 1; further, in this embodiment, the outer side of the second screw 7 is provided with a second external thread 9, and the inner side of the compensation sleeve 3 is provided with an internal thread that matches the second external thread 9, and the second external thread 9 and the first external thread are arranged in opposite directions of rotation; when the locking bolt 4 rotates forward and enters the screw hole 8, the second external thread 9 rotates in the reverse direction to drive the compensation sleeve 3 to move away from the actuator 1, thereby abutting the wing ear 12 against the inner side of the thin wall 2, and assembling the thin wall 2 and the actuator 1.

[0028] In addition, in order to ensure the strength of the wing ear 12, the side of the wing ear 12 close to the thin wall 2 is made of soft materials such as rubber, and the side away from the thin wall 2 is made of metal. When the locking bolt 4 is rotated, the compensation sleeve 3 will rotate with it. At this time, a magnet can be used to increase the rotation resistance, so that the wing ear 12 contacts the inner side of the thin wall 2. Then, since the inner side of the thin wall 2 is arc-shaped, there will be a friction force between the wing ear 12 and the inner side of the thin wall 2 after contact. This friction force can correct the contact surface between the wing ear 12 and the thin wall 2 to ensure The wing ear 12 and the thin wall 2 are always in contact, so as to complete the assembly; the entire assembly structure from the inside to the outside is the acting body 1, the locking bolt 4, the compensation sleeve 3, and the thin wall 2; the entire assembly structure is completed. It should be noted that the rotation correction of the wing ear 12 before it contacts the thin wall 2 can be achieved by the gravity of the wing ear 12 itself, as long as the accuracy and smoothness of the second external thread 9 are sufficient; if it is not sufficient, it can also be achieved by the following means. Specifically, the thin wall 2 is provided with limiting holes 13 on both sides of the through hole 5. Specifically, the limiting holes 13 are set on both sides of the short axis of the elliptical through hole 5. When the compensation sleeve 3 rotates, the pin is inserted into the limiting hole 13 to complete the limitation of the wing ear 12 so that it can be in contact with the thin wall 2.

[0029] In order to ensure that the locking bolt 4 can bear force well, an axial force bearing structure is provided at the end of the second screw rod 7. The axial force bearing structure is a "flat mouth" or a "plum blossom mouth" for rotating the locking bolt 4.

[0030] In addition, in this embodiment, the gap compensation between the actuator 1 and the thin wall 2 is completed by the locking bolt 4, and the abutment is completed by the wing ears 12 and the thin wall 2. It should be noted that the wing ears 12 should be provided in three groups or more to better complete the 360-degree fixation of the actuator 1 and the thin wall 2, thereby completing the assembly of the actuator 1 and the thin wall 2.

[0031] In this embodiment, in order to avoid excessive rotation of the locking bolt 4, color markings may be provided on the locking bolt 4 and the compensation sleeve 3 to assist the operator in operation.

[0032] Embodiment 2

[0033] like Figure 6As shown, in the present embodiment, a gap assembly structure between a thin wall 2 and an actuator 1 is mainly disclosed, and its main structure is exactly the same as that of the first embodiment. The difference is that, in the present embodiment, the structure of the locking bolt 4 driving the compensation sleeve 3 is different from that of the first embodiment. Specifically, a protrusion 10 is provided on the outer side of the second screw rod 7, and a slide groove 11 is provided on the inner side of the compensation sleeve 3. The protrusion 10 is slidably arranged in the slide groove 11, and the slide groove 11 is extended along the axial diameter of the compensation sleeve 3; that is, under the rotation of the locking bolt 4, the protrusion 10 slides in the slide groove 11, and the slide groove 11 slides in the direction away from the actuator 1, thereby abutting the wing ear 12 against the inner side of the thin wall 2; preferably, in order to reduce the interactive resistance of the protrusion 10 in the slide groove 11, the circle spacing of the slide groove 11 should be set as large as possible; but it should not exceed 3 times the length of the compensation sleeve 3, such as Figure 7 As shown, it is a development diagram of the slide groove with the axis of the compensation sleeve 3 as the development surface.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
