[0001] The present invention belongs to the technical field of mechanical structure spacing measurement, and particularly relates to a mechanism for measuring the spacing of components in a narrow space. Background Art

[0002] With the rapid development of modern mechanical equipment, the technologies of more and more large-scale mechanical equipment are becoming more and more mature. However, there are still some defects in the manufacturing of some large-scale parts at present. For example, some key equipment required for the manufacturing of large-scale parts at present, such as five-axis linkage machining centers, high-precision grinders, electron beam welding, etc., in terms of quality control, the detection technologies and equipment for internal defect detection and high-precision dimension measurement of large-scale parts are relatively backward. This leads to insufficient installation accuracy of large-scale parts and various problems during the operation of the equipment. For the installation accuracy problems existing in the equipment, during the operation of the equipment, the equipment may not operate normally due to installation accuracy problems. When it is necessary to detect where there are errors, it is not easy to perform manual operations in a small space at this time. Especially when these key components are located between two narrow planes, a specific mechanical mechanism tool is required for detection at this time.

[0003] Based on this, the present application proposes a mechanism for measuring the spacing of components in a narrow space. Summary of the Invention

Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present 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 only used to explain the present invention and are not used to limit the present invention.

[0026] It can be understood that the terms "first", "second", etc. used in the present application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish one element from another.

[0027] As Figure 1 and Figure 5 shown, in one embodiment, a mechanism for measuring the distance between components in a narrow space is proposed. The mechanism includes:

[0028] A rotating part 1;

[0029] A supporting part 2, which can rotate relative to the rotating part 1 independently, and is used as the installation carrier of the overall mechanism;

[0030] A clamping part 3, which is driven by the rotating part 1 to rotate; and

[0031] A telescopic measuring part 4, which is installed on the clamping part 3 and is used to measure the distance between components.

[0032] In a case of an embodiment of the present invention, the rotating part 1 can be a handle or a component that can provide rotational power. The rotating part 1 can include a rotating handle and a rotating rod. The rotating rod can be made of 316L stainless steel, and the handle can be made of wood material to reduce the overall mass. Of course, the rotating part 1 can also be designed in other forms of structures, and the embodiments of the present invention do not specifically limit this here.

[0033] In the actual application of the embodiments of the present invention, the supporting part 2 serves as the installation carrier of the overall mechanism. The telescopic measuring part 4 is clamped and fixed by the clamping part 3. The telescopic measuring part 4 is extended into the measuring position. The supporting part 2 is placed on the surface of the object to be measured by pressing with the hand. Then the rotating part 1 rotates, driving the telescopic measuring part 4 to rotate, to measure whether the two components are in contact.

[0034] As Figure 2 shown, as a preferred embodiment of the present invention, the support portion 2 is of a cylindrical structure, and the clamping portion 3 is inside the cylindrical structure.

[0035] In one case of the embodiment of the present invention, the support portion 2 may be of a cylindrical structure, made of 316L stainless steel as the material. Considering the stress condition of the main support structure, Q235 steel with better stress resistance may also be used. The support portion 2 can be connected to the rotating portion 1 through a bearing to ensure smooth movement.

[0036] More preferably, a plurality of opening grooves are provided on the surface of the cylindrical structure or it is a hollow structure. In the embodiment of the present invention, the overall height of the support portion 2 is set to 90 mm, the diameter is 200 mm, and the wall thickness is 5 mm. The opening grooves can be evenly distributed at 120 degrees. The purpose of providing the opening grooves or making it a hollow structure is that when the support portion 2 contacts the electrode support surface, the line of sight will not be blocked, and the operator can still observe the movement state of the telescopic measuring portion 4.

[0037] In addition, as a preference, a gasket made of materials such as rubber can be added on the contact surface between the support portion 2 and the electrode support surface to increase the friction and ensure the stability of the overall mechanism during measurement.

[0038] As Figure 2 shown, as another preferred embodiment of the present invention, the clamping portion 3 includes a clamping seat 301 connected to the rotating portion 1. An active block 302 that can move relative to it is provided inside the clamping seat 302. The clamping seat 302 and the active block 302 are used to clamp the telescopic measuring portion 4, and the position of the active block 302 is adjusted by an adjusting rod 303 provided on the clamping seat 302.

[0039] In the actual application of the embodiment of the present invention, the adjusting rod 303 can actually be understood as a screw rod. Through the movement of the screw pair, the active block 302 is driven to move relative to the clamping seat 302, thereby clamping or releasing the telescopic measuring portion 4. In the embodiment of the present invention, the clamping portion 3 can also be clamped in other forms, such as being fixed by screws, buckles, jacket sleeves, etc. The embodiment of the present invention does not make specific limitations here.

[0040] As Figure 3 shown, as another preferred embodiment of the present invention, the telescopic measuring portion 4 includes:

[0041] A first rod body 402, connected to the clamping portion 3 through a height adjusting unit 401. The first rod body 402 includes a horizontal section and an inclined section, and the inclined section has a preset inclination angle relative to the horizontal section;

[0042] At least one second rod body 404 is connected to the first rod body 402 through a length adjustment unit 403. When the number of the second rod bodies 404 is two or more, multiple second rod bodies 404 are connected through the length adjustment unit 403.

[0043] In one case of the embodiment of the present invention, the preset inclination angle can be 90°. In this way, not only can the telescopic measuring part 4 be adjusted in the length direction, but also can be adjusted in the height direction, so as to be inserted into a narrow gap. Both the first rod body 402 and the second rod body 404 are flat strip-shaped structures.

[0044] As Figure 3 shown, as another preferred embodiment of the present invention, the height adjustment unit 401 includes a first pipe body 4012, and the first pipe body 4012 is slidably matched with the horizontal section or the inclined section. A locking knob 4011 is installed on the first pipe body 4012.

[0045] In the embodiment of the present invention, the matching manner between the height adjustment unit 401 and the first pipe body 4012 is actually a sleeve structure. The horizontal section or the inclined section can slide inside or outside the first pipe body 4012 and is locked and fixed through the locking knob 4011. Of course, other forms can also be adopted, such as a slide rail and slider structure, which is not specifically limited in the embodiment of the present invention.

[0046] As Figure 4 shown, as another preferred embodiment of the present invention, the length adjustment unit 403 includes a second pipe body 4031, and the second pipe body 4031 is slidably matched with the first rod body 402 and the second rod body 404. Claws 4033 are hinged at the ends of the second pipe body 4031, a torsion spring 4032 is installed at the claws 4033, and a plurality of continuous teeth for cooperating with the claws 4033 are provided on both the first rod body 402 and the second rod body 404.

[0047] In the embodiment of the present invention, the structure of the length adjustment unit 403 is actually also a sleeve structure. In contrast, in the embodiment of the present invention, the cooperation between the claws 4033 and the teeth can conveniently realize the length adjustment.

[0048] In one case of the embodiment of the present invention, both the first rod body 402 and the second rod body 404 can be made of 316L stainless steel material. When length adjustment is required, the claws 4033 are pressed, the torsion spring 4032 is compressed, the claws 4033 are disengaged from the teeth, and after adjusting to a suitable length, the claws 4033 are released. Under the action of the torsion spring 4032, the claws 4033 are engaged with the teeth to realize position locking and complete the length adjustment.

[0049] Combined with the above embodiments, the design purpose of the present invention is to measure whether two narrow planes are in contact. For example, between two electrodes, if they are in contact, a short circuit phenomenon will occur. When the present invention is actually applied, the adjusted telescopic measuring part 4 is inserted into the round hole, the telescopic measuring part 4 is fixed by the clamping part 3, and finally the driving is performed by the rotating part 1. If the two planes are not in contact with each other, the telescopic measuring part 4 can rotate a complete circle during driving. If the two planes are in contact, it cannot rotate a complete circle. When rotating close to the contact point, the rotation resistance increases until the rotation stops, and the stopping position is approximately the position of the contact point.

[0050] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0051] The above-described embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the invention patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent of the present invention should be subject to the appended claims.

[0052] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
