Description

Technical Field

[0001] The utility model relates to the technical field of assembly tooling, in particular to a nut assembly tooling for an iron gas storage cylinder. Background Art

[0002] The iron air cylinder is a key component in the automobile braking system. Its main function is to store the gas compressed by the air compressor (air pump). These gases are used in the automobile braking, horn and other systems.

[0003] The nut assembly used on the gas cylinder plays a key role in the entire system. By tightening the nut, sufficient pre-tightening force can be generated to form a reliable connection between the various components of the gas cylinder to prevent gas leakage. It can also be used to adjust the air pressure or flow inside the gas cylinder. For example, by adjusting the position or tightening degree of the nut, the air pressure inside the gas cylinder can be changed to meet the needs of different systems or equipment.

[0004] The nut assembly usually also includes a spring and a sealing ring. The spring plays a pre-tightening role in the nut assembly. When the nut is tightened, the spring is compressed and generates elastic force. This elastic force can increase the friction between the nut and the bolt, thereby increasing the tightening force. The spring can also compensate for tiny displacements caused by factors such as vibration and temperature changes, maintain the stability of the tightening force, and prevent the nut from loosening. The sealing ring is mainly used for sealing.

[0005] In the prior art, when assembling the nut assembly, the spring and the sealing ring are often directly put on the nut assembly. However, such an assembly method is often accompanied by the spring being off-center, skewed, or even stuck, affecting the normal use of the air cylinder, and the sealing ring is also prone to flanging, affecting the sealing effect. Utility Model Content

[0006] The purpose of the utility model is to provide a nut assembly tool for an iron gas storage cylinder to solve the following technical problems:

[0007] How to prevent the spring from skewing and the sealing ring from flanging when assembling the automobile iron air tank.

[0008] The purpose of the utility model can be achieved through the following technical solutions:

[0009] A nut assembly tool for an iron gas cylinder, characterized in that it includes a fixing nut, a nut base is fixedly installed on one side of the fixing nut, two limit blocks are symmetrically arranged at the edge of the nut base on one side away from the fixing nut, and the opposite sides of the two limit blocks are flat and parallel to each other; a threaded rod core is vertically connected to the center of the side of the nut base away from the fixing nut.

[0010] As a further solution of the utility model: the threaded rod core includes a thick rod core and a thin rod core which are coaxially connected, wherein the thick rod core is connected to the center of the nut base.

[0011] As a further solution of the utility model: the height of the thick rod core is the same as the height of the limit stopper.

[0012] As a further solution of the utility model: a stretching block is movably provided on the side of the limit block away from the nut base, the stretching block has the same shape as the nut base, and the opposite sides of the two limit blocks are flat and parallel to each other.

[0013] As a further solution of the utility model: a handle is installed on the outer side of the stretching block.

[0014] Beneficial effects of the utility model:

[0015] The utility model passes the hexagonal nut assembly through the thick rod core and places it between the two limit blocks. At this time, the two straight sides of the nut fit with the inner sides of the two limit blocks, and then the spring and the sealing ring are inserted into the nut assembly, so that the spring is centered without being skewed or stuck, and the sealing ring will not be flanging. When the inner hole diameter of the nut assembly is small, the nut can be inserted into the thin rod core, and the bottom of the nut is placed on the thick rod core. Then, a part of the stretching block is pulled out by the handle, so that the two straight sides of the nut fit with the inner sides of the two limit blocks, and then the spring and the sealing ring are assembled. Therefore, the tooling is also suitable for nut assemblies with two different inner diameters. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 As shown, the utility model is a nut assembly tool for an iron gas storage cylinder, which is composed of a fixing nut 100, a nut base 200, a stretching stopper 300 and a threaded rod core 400, wherein the nut base 200 is fixedly installed on one side of the fixing nut 100, and the axis of the nut base 200 and the fixing nut 100 are colinear, and a limit stopper 201 is respectively installed on the edge of the side of the nut base 200 away from the fixing nut 100, and the opposite side of the two limit stops 201 is a plane and the two planes are parallel to each other.

[0024] A threaded rod core 400 is fixedly connected to the center of the side where the limit stop 201 is installed on the nut base 200, and the threaded rod core 400 consists of a thick rod core 401 and a thin rod core 402, wherein the thick rod core 401 is fixedly connected to the center of the nut base 200, and the thin rod core 402 is fixedly connected to the center of one end of the thick rod core 401 away from the nut base 200, and the axes of the thick rod core 401 and the thin rod core 402 are collinear; the diameter of the thin rod core 402 is smaller than the diameter of the thick rod core 401, and the height of the thick rod core 401 is the same as the height of the limit stop 201.

[0025] It should be noted that the sizes of the thick rod core 401 and the thin rod core 402 are determined according to the inner hole diameter of the actual nut assembly, so that the nut assembly can be just inserted into the thick rod core 401 or the thin rod core 402.

[0026] A stretching block 300 is movably provided on one side of the two limit blocks 201 away from the fixing nut 100. The stretching block 300 has the same shape as the nut base 200. The opposite sides of the two limit blocks 201 are flat and parallel to each other. Handles 301 are respectively installed on the outer sides of the two stretching blocks 300 for extracting the stretching blocks 300.

[0027] The working principle of the utility model is:

[0028] When in use, the hexagonal nut assembly is passed through the thick rod core 401 and placed between the two limit blocks 201. At this time, the two straight sides of the nut are in contact with the inner sides of the two limit blocks 201. Then, the spring and the sealing ring are inserted into the nut assembly to ensure that the spring is centered and not skewed or stuck, and the sealing ring will not be flanging. When the inner hole diameter of the nut assembly is small, the nut can be inserted into the thin rod core 402. At this time, the bottom of the nut is placed on the thick rod core 401. Then, a part of the stretching block 300 is pulled out through the handle 301 to make the two straight sides of the nut fit with the inner sides of the two limit blocks 201. Then, the spring and the sealing ring can be assembled. Therefore, the tooling is also suitable for nut assemblies with two different inner diameters.
