Description

Technical Field

[0001] The present invention relates to the field of pressing tooling, and in particular to an armature assembly pressing tooling. Background Art

[0002] In the fields of industrial automation and electrical control, the armature assembly, a critical transmission and switching component, is widely used in electromagnets, relays, and various sensors. Its performance directly impacts the stability and reliability of the entire system. Traditional armature assembly design often involves the precise coordination of multiple components, with the pressing process between the armature assembly and the spring tube being particularly critical.

[0003] In traditional manufacturing, the armature assembly is typically composed of a stopper assembly and a spring tube, assembled using a specific press-fitting technique. As a core component, the spring tube features a thin-walled design. Its excellent elastic properties allow for energy storage and release, providing the foundation for the armature assembly's rapid response and precise movement.

[0004] However, it is precisely this thin-wall design that makes the spring tube susceptible to external forces during the pressing process, especially in the thin-walled areas. Once the force is uneven or excessive, it may cause local deformation or even breakage of the spring tube, seriously affecting the product yield and service life. Summary of the Invention

[0005] The present application provides an armature assembly pressing tool, which can solve the technical problem in the prior art that the spring tube is easily affected by external forces during the pressing process, resulting in local deformation or even breakage.

[0006] The embodiment of the present application provides an armature assembly pressing tool, which includes:

[0007] A tubular fixing seat, wherein a columnar support rod is provided on the tubular fixing seat, and the diameter of the columnar support rod is smaller than the diameter of the spring tube to be processed;

[0008] And, a clamping and fixing sleeve, the clamping and fixing sleeve is arranged outside the tubular fixing seat, a spring tube limiting hole is reserved on the clamping and fixing sleeve, the diameter of the spring tube limiting hole is larger than the diameter of the spring tube to be processed, and the columnar support rod carrying the spring tube to be processed can pass through the spring tube limiting hole; a plurality of positioning pins are provided on the clamping and fixing sleeve, and a clamping station for fixing the armature assembly is formed between adjacent positioning pins.

[0009] By adopting the above technical solution, the diameter of the columnar support rod is smaller than the diameter of the spring tube to be processed, so that the spring tube to be processed can be inserted into the columnar support rod, so that the columnar support rod can support the spring tube to be processed from the inside of the spring tube to be processed; the diameter of the spring tube limiting hole is larger than the diameter of the spring tube to be processed, so that the columnar support rod carrying the spring tube to be processed can partially pass through the spring tube limiting hole, thereby limiting and fixing the spring tube to be processed from the outside of the spring tube to be processed. A clamping station for fixing the arm assembly is formed between adjacent positioning pins. The operator can place the arm assembly into the clamping station, and the protruding portion of the arm assembly can be inserted into the spring tube to be processed. The positioning pins can limit and fix the arm assembly to facilitate subsequent pressing operations. Since the spring tube to be processed has support limits inside and outside, and the arm assembly also has corresponding limit workpieces, the relative displacement of the spring tube to be processed and the arm assembly during the pressing process can be reduced, and the spring tube to be processed can be supported at the same time during the pressing process, thereby reducing the possibility of deformation or breakage of the spring tube to be processed during the pressing process, and solving the problem in the prior art that the spring tube is easily affected by external forces and suffers local deformation or even breakage during the pressing process.

[0010] In one embodiment, an observation window is provided on the clamping and fixing sleeve.

[0011] By adopting the above technical solution, it is convenient for an operator to observe the pressing operation of the armature assembly and the spring tube to be processed.

[0012] In one embodiment, a support base is provided below the tubular fixing seat.

[0013] By adopting the above technical solution, the clamping and fixing sleeve can be temporarily assembled on the supporting base to provide more stable support for the overall structure.

[0014] In one embodiment, the clamping and fixing sleeve includes two clamping and fixing units, the positioning pin is arranged on the surface of the clamping and fixing unit, and a semicircular groove is opened on the opposite side of the clamping and fixing unit. The two semicircular grooves are spliced ​​together to form the spring tube limiting hole.

[0015] By adopting the above technical solution and the splicing installation method, the operator can splice the two clamping and fixing units from both sides of the cylindrical support rod to form a whole after fixing the spring tube to be processed, which makes installation more convenient.

[0016] In one embodiment, an armature assembly press fitting further includes:

[0017] A position limiting and fastening sleeve is provided outside the two clamping and fixing units.

[0018] By adopting the above technical solution, after the two clamping and fixing units are assembled to form a clamping and fixing sleeve, the limiting fastening sleeve is arranged outside the clamping and fixing unit, which can temporarily fix the two clamping and fixing units, thereby reducing the possibility of the two clamping and fixing units separating due to the extrusion force during the pressing operation.

[0030] By adding a columnar support rod to the tubular fixing seat, the spring tube can be inserted into the columnar support rod, and then the clamping fixing sleeve is arranged outside the tubular fixing seat. A spring tube limiting hole is reserved on the clamping fixing sleeve, so that when the clamping fixing sleeve is arranged outside the tubular fixing seat, the columnar support rod loaded with the spring tube can pass through the spring tube limiting hole. The spring tube limiting hole can cooperate with the columnar support rod to support and fix the inner and outer sides of the spring tube. A plurality of positioning pins are provided on the clamping fixing sleeve, and a clamping position is formed between adjacent positioning pins, so that the operator can put the arm assembly into the clamping position to limit the arm assembly, and insert the protruding part of the arm assembly into the spring tube, and the arm assembly can be pressed by a press or other tooling, which solves the problem in the prior art that the spring tube is easily affected by external force during the pressing process and locally deformed or even broken.

[0035] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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 this application.

[0036] The embodiment of the present application provides an armature assembly pressing tool, which can solve the problem in the prior art that the spring tube is easily affected by external forces during the pressing process, resulting in local deformation or even breakage.

[0037] Reference Figure 1 Schematic diagram of the exploded structure of an armature assembly pressing tool in this application and Figure 2 The present application discloses a structural diagram of an armature assembly pressing tool equipped with a spring tube and an armature assembly. The present application discloses an armature assembly pressing tool, including a tubular fixing seat 1 and a clamping fixing sleeve 2. The tubular fixing seat 1 is used to carry the spring tube 4 to be processed, and the clamping fixing sleeve 2 is used to carry the armature assembly 5 and limit the spring tube. A columnar support rod 11 is protruding from the tubular fixing seat 1, and the diameter of the columnar support rod 11 is smaller than the diameter of the spring tube 4 to be processed, so that the spring tube 4 to be processed can be inserted into the columnar support rod 11, so that the columnar support rod 11 can support the spring tube 4 to be processed from the inside of the spring tube 4 to be processed; the clamping and fixing sleeve 2 is sleeved on the outside of the tubular fixing seat 1, and a spring tube limiting hole is opened in the middle of the clamping and fixing sleeve 2. The diameter of the spring tube limiting hole is larger than the diameter of the spring tube 4 to be processed, so that the columnar support rod 11 carrying the spring tube 4 to be processed can pass through a part of the spring tube limiting hole, and then play a role of limiting and fixing the spring tube 4 to be processed from the outside of the spring tube 4.

[0038] The clamping sleeve 2 is provided with a plurality of positioning pins 22, and a clamping station for fixing the arm assembly 5 is formed between adjacent positioning pins 22. The operator can place the arm assembly 5 into the clamping station, and the protruding portion of the arm assembly 5 can be inserted into the spring tube 4 to be processed. The positioning pins 22 can limit and fix the arm assembly 5 to facilitate the subsequent pressing operation. Since the spring tube 4 to be processed has support and limit functions both inside and outside, and the arm assembly 5 also has corresponding limit workpieces, the relative displacement between the spring tube 4 to be processed and the arm assembly 5 during the pressing process can be reduced, and the spring tube 4 to be processed can be supported at the same time during the pressing process, thereby reducing the possibility of deformation or fracture of the spring tube 4 to be processed during the pressing process, and solving the problem in the prior art that the spring tube is easily affected by external forces during the pressing process, resulting in local deformation or even fracture.

[0039] More specifically, in this embodiment, the clamping and fixing sleeve 2 includes two clamping and fixing units 21. The clamping and fixing units 21 are semicircular in shape. The two clamping and fixing units 21 are assembled to form a cylinder. Semicircular grooves are provided on two opposing surfaces of the clamping and fixing units 21. The two semicircular grooves are assembled to form a spring tube limiting hole. Through the assembly method, after the operator fixes the spring tube 4 to be processed, the two clamping and fixing units 21 can be assembled from both sides of the cylindrical support rod 11 to form a whole, which makes installation more convenient. Four locating pins 22 are specifically provided. The locating pins 22 are welded to the clamping and fixing units 21 to increase the connection strength between the locating pins 22 and the clamping and fixing units 21. Two locating pins 22 are provided on a single clamping and fixing unit 21. The two locating pins 22 are spaced apart along the diameter direction of the clamping and fixing unit 21, and a clamping station is formed between the two locating pins 22. After the two clamping and fixing units 21 are assembled to form the clamping and fixing sleeve 2, the operator can insert the protruding portion of the armature assembly into the spring tube 4 to be processed, and clamp the crossbar portion of the armature assembly into the clamping station to complete the limiting process of the armature assembly.

[0040] Furthermore, in order to facilitate the operator to observe the pressing operation of the armature assembly and the spring tube 4 to be processed, an observation window 23 is also provided on the clamping and fixing sleeve 2. In this embodiment, observation windows 23 are provided on the side walls of the two clamping and fixing units 21. The observation window 23 is specifically arranged at one end of the side wall of the clamping and fixing unit 21 close to the top surface, so that the operator can observe flexibly from multiple angles. No matter whether standing in front of or on the side of the machine, every subtle change in the contact between the armature assembly and the spring tube 4 to be processed can be easily captured.

[0041] In order to provide higher strength support for the armature assembly and the pressing operation of the spring tube 4 to be processed, a support base 12 is further provided under the tubular fixing seat 1. The size of the support base 12 is larger than that of the clamping fixing sleeve 2, so that the clamping fixing sleeve 2 can be temporarily assembled on the support base 12 to provide more stable support for the overall structure.

[0042] To reduce the possibility of the two clamping units 21 separating due to the squeezing force during the pressing operation, a limiting fastening sleeve 3 is additionally provided on the outside of the two clamping units 21. After the two clamping units 21 are assembled to form the clamping sleeve 2, the limiting fastening sleeve 3 is placed on the outside of the clamping units 21 to temporarily secure the two clamping units 21. A gripping opening 31 is also provided on the side wall of the limiting fastening sleeve 3 to facilitate removal of the limiting fastening sleeve 3. In one embodiment of the present application, the gripping opening 31 is positioned corresponding to the observation window 23, facilitating removal without interfering with the operator's ability to observe the internal pressing operation.

[0043] In order to extend the service life of an armature assembly pressing tool and improve the workpiece strength of the limiting fastening sleeve 3, tubular fixing seat 1, and clamping fixing sleeve 2, the limiting fastening sleeve 3, tubular fixing seat 1, and clamping fixing sleeve 2 are all made of rigid metal materials, such as stainless steel, iron, and the like. These materials not only have excellent physical strength, which can withstand the performance degradation of the limiting fastening sleeve 3, tubular fixing seat 1, and clamping fixing sleeve 2 caused by stress, wear, and environmental factors during daily work, but also ensure that the limiting fastening sleeve 3, tubular fixing seat 1, and clamping fixing sleeve 2 have good stability and can be used for a long time. More specifically, stainless steel can ensure that the limiting fastening sleeve 3, tubular fixing seat 1, and clamping fixing sleeve 2 maintain a smooth surface finish in various harsh environments, reduce component failure caused by oxidation and rust, and thus extend the service life of the limiting fastening sleeve 3, tubular fixing seat 1, and clamping fixing sleeve 2.
