Description

Technical Field

[0001] The present application relates to the field of production and manufacturing technology, and in particular to an assembly device. Background Art

[0002] The electromagnetic flapper valve has the advantages of automatic control, long life, good sealing, reversibility, etc., and can adapt to the working environment under high vacuum conditions. The electromagnetic flapper valve can be used in a variety of different scenarios, such as vacuum metallurgy, power system, petrochemical, gas control scenarios, etc.

[0003] The electromagnetic flapper valve is usually composed of a valve core assembly and a valve core armature assembly. A corresponding spring assembly is also provided between the valve core assembly and the valve core armature to perform functions such as control, buffering and balancing. In the assembly process of the existing electromagnetic flapper valve, it is usually necessary to manually put the valve core armature on the valve core assembly, and then use a hammer or other device to fix the valve core assembly and the valve core armature to complete the assembly. Due to the elastic pressure of the spring assembly, it is usually necessary for multiple workers to handle it, and the labor cost is high. In addition, the stability of the manual fixation of the valve core assembly and the valve core armature is poor, which is easy to cause accidental injury to the workers. Hammers and other devices may also cause damage to the surface of the valve core armature. Therefore, the current assembly efficiency of the electromagnetic flapper valve is low and the quality is unstable, which cannot meet the current assembly needs. Utility Model Content

[0004] In view of this, an object of an embodiment of the present application is to provide an assembly device to improve the problems of low assembly efficiency and unstable quality of electromagnetic baffle valves in the prior art.

During assembly, there is no need to manually provide extrusion force to compress the elastic member for assembly. The guide member and the valve core armature can be automatically assembled based on the power provided by the pressure assembly, which effectively reduces the cost of manual processing and reduces the adverse effects on the staff, the valve core armature and the valve core assembly during manual assembly. In addition, after the guide member reaches the target position inside the valve core armature, that is, after the valve core armature and the valve core assembly have completed the depth positioning, the corresponding positioning assembly can also be used.

[0023] The positioning member is used to pass through the first through hole, the first through hole on the valve core armature, and the second through hole on the guide member.

[0024] In the above implementation process, in order to make corresponding movements in the first through hole to realize the axial positioning function, the positioning assembly may include an elastic member and a connected positioning member, one end of the elastic member is fixed, and the other end is connected to the positioning member to provide the positioning member with an elastic force in a first direction to enter the first through hole, and when the valve core armature and the valve core assembly are fixed by the fixing member, in order not to affect the normal use of the fixing member, the elastic member can also drive the positioning member to move in a second direction opposite to the first direction, that is, through the elastic deformation of the elastic member, the positioning member is driven to reciprocate in the first through hole, so that the positioning member can pass through the first through hole, the first through hole on the valve core armature and the second through hole on the guide member to axially position the valve core armature and the guide member, and automatically withdraw after completing the axial positioning to realize subsequent assembly and fixation.

[0036] In the above implementation process, since the pressure component provides a relatively constant power, and for different types of electromagnetic flapper valves, the specific target positions of the valve core armature and the valve core component during deep positioning are different, the position of the guide member inside the valve core armature can be further adjusted by the adjustment component after the pressure component provides the corresponding constant power. The adjustment component includes a housing and an adjustment member, and the adjustment member is sleeved on the outer surface of the housing through a thread set on the outer surface of the housing, so that the adjustment member can adjust the position of the guide member inside the valve core armature based on the selection of the thread, to achieve high-precision deep positioning, and is suitable for adjusting a variety of different types of valve core components, effectively improving the scope of application of the assembly device.

When the rotating structure is in operation, it is arranged in contact with the base flange surface of the valve core assembly.

DETAILED DESCRIPTION

[0054] The technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the embodiments of the present application.

[0055] Electromagnetic flapper valves can be used in a variety of scenarios such as vacuum metallurgy, power systems, petrochemicals, and gas control. For example, electromagnetic high vacuum flapper valves play a key role in railway vehicle air conditioning systems, used to control air circulation and adjust the environment in the carriage; in the vacuum metallurgical process, it is necessary to strictly control the gas flow and vacuum degree, and the electromagnetic flapper valve can effectively cut off or conduct the airflow to ensure the smooth progress of the metallurgical process; in the power industry, especially in thermal power plants and nuclear power plants, electromagnetic flapper valves are widely used to cut off and regulate the flow of various media to ensure the stable operation of the system; the petrochemical industry involves a variety of complex process flows and media, and the electromagnetic flapper valve can adapt to different working environments and control the flow of corrosive fluids, high-density fluids, and fluids with more particulate matter; in the process of shipbuilding and maintenance, electromagnetic flapper valves are used to control the gas circulation in the cabin to ensure the safety and comfort of the ship; in the field of aerospace, electromagnetic flapper valves play a key role in vacuum systems, used to cut off or conduct airflow to ensure the normal operation of spacecraft.

[0056] The electromagnetic flapper valve is usually composed of a valve core assembly and a valve core armature assembly. A corresponding spring assembly is also arranged between the valve core assembly and the valve core armature to perform functions such as control, buffering and balancing. In the electromagnetic flapper valve, the role of the spring between the valve core and the armature is mainly reflected in the following aspects: Balancing the valve load: One of the main functions of the spring is to balance the load of the valve. When the valve is closed, the spring provides a closing force to ensure that the valve can be firmly closed and the medium in the pipeline is accurately controlled at the required position. Control the flow rate and pressure of the liquid: When the valve is opened or closed, the spring also plays a role in controlling the flow rate and pressure of the liquid. It avoids too fast or too slow flow, prevents unnecessary losses, and ensures the normal operation of the valve and prolongs the service life of the valve. Buffering and reducing impact force: During the process of energizing and de-energizing the electromagnetic coil, the valve core will move left and right. In this process, the spring plays a certain buffering role to prevent the valve core from exerting too much impact on the valve body and protect the valve and related equipment from damage. Realize the automation of electromagnetic control: In the solenoid valve, the spring is an important part of the automatic control. When the power is on, the attraction generated by the electromagnet interacts with the elastic force of the spring to open or close the valve. When the power is off, the spring plays a major role, pushing the valve core back to its initial position to close the valve.

[0057] During the assembly process of the existing electromagnetic flapper valve, it is usually necessary to manually put the valve core armature sleeve on the valve core assembly, and then use a hammer or other device to fix the valve core assembly and the valve core armature to complete the assembly. Due to the elastic pressure of the spring assembly, it is usually necessary for multiple workers to handle it. The valve core assembly needs to be pushed manually and the valve core assembly needs to be adjusted in a corresponding state. The labor cost is high. In addition, the stability of the valve core assembly and the valve core armature when manually fixed is poor, which can easily cause accidental injuries to workers, such as being bounced open by the elastic force of the spring assembly, being hit by a hammer, etc. In addition, hammers and other devices may also cause damage to the surface of the valve core armature when working. Therefore, the current electromagnetic flapper valve has low assembly efficiency and unstable quality, and cannot meet current assembly needs.

[0058] In order to solve the above problems, the present application provides an assembly device. Figure 1 , Figure 1 This is a schematic structural diagram of an assembly device provided in an embodiment of the present application. The assembly device may include: an adjustment component 110, a pressure component 120, a mounting structure 130, a positioning component 140 and a fixing mechanism 150.

[0059] The mounting structure 130 is used to fix the valve core armature 210 to be assembled.

[0060] Optionally, the mounting structure 130 can fix the valve core armature 210 to be assembled by means of interlocking, clamping, etc., and the valve core armature 210 can be set to a hollow cylindrical structure with an opening.

[0061] Optionally, the first end of the adjustment component 110 is connected to the pressure component 120, and the second end of the adjustment component 110 is configured to be arranged in contact with the base flange surface of the valve core component 220 to be assembled under working conditions; the adjustment component 110 is used to push the guide member 221 provided with an elastic structure in the valve core component 220 to the target position inside the valve core armature 210 based on the power provided by the pressure component 120. Since the outer part of the guide member 221 is usually provided with a corresponding elastic member 222, such as a spring and other structures, to perform functions such as control, buffering and balancing, when the guide member 221 is deeply inserted into the valve core armature 210, a large resistance will be generated due to the elastic force of the elastic member 222. In order to resist this resistance, a corresponding pressure component 120 and an adjustment component 110 can be set to provide the guide member 221 with a power opposite to the resistance and greater than the resistance, so that there is no need for manual pushing, and the guide member 221 can be automatically pushed into the valve core armature 210 for assembly. In addition, a corresponding adjustment component 110 can also be set to perform depth adjustment on the actual position of the guide member 221 inside the valve core armature 210 so that the guide member 221 can reach the corresponding target position, which is the corresponding position in the depth dimension inside the valve core armature 210 where the valve core armature 210 and the guide member 221 are deeply aligned.

[0062] By way of example, the pressure assembly 120 may include a cylinder structure or the like that can provide a pressure opposite to the elastic force of the elastic member 222 between the guide rod and the valve core armature 210, so as to automatically press the guide rod into the valve core armature 210. The adjustment assembly 110 may be configured as a structure that can fine-tune the position of the guide member 221. For example, the adjustment assembly 110 may include a telescopic rod, a spiral structure, or the like that can be used for length adjustment.

[0063] The valve core armature 210 to be assembled is fixed by the mounting structure 130, and the guide member 221 of the valve core assembly 220 corresponding to the valve core armature 210 is pushed to the target position inside the valve core armature 210 by the adjusting assembly 110 and the pressure assembly 120. There is a corresponding elastic member 222 between the guide member 221 and the valve core armature 210. During assembly, there is no need for manual extrusion force to compress the elastic member 222 for assembly. The guide member 221 and the valve core armature 210 can be automatically assembled based on the power provided by the pressure assembly 120, which effectively reduces the cost of manual processing and reduces the adverse effects on the staff, the valve core armature 210 and the valve core assembly 220 during manual assembly.

[0064] It should be noted that the positioning assembly 140 is used to pass through the mounting structure 130 to axially position the valve core armature 210 and the guide member 221; the fixing mechanism 150 is used to drive the connected fixing member to pass through the mounting structure 130, the valve core armature 210 and the guide member 221 to fix the valve core armature 210 and the guide member 221. After the guide member 221 reaches the target position inside the valve core armature 210, that is, after the valve core armature 210 and the valve core assembly 220 have completed the depth positioning, the corresponding positioning assembly 140 can also be used. When the positioning assembly 140 is working, it passes through the mounting structure 130 to axially position the valve core armature 210 and the guide member 221, so that the valve core armature 210 and the guide member 221 can be aligned in the axial direction, and the fixing mechanism 150 is used to drive the corresponding fixing member to pass through the valve core armature 210 and the valve core assembly 220 that have completed the axial positioning for fixed assembly.

[0065] Optionally, a first through hole 211 is provided on the valve core armature 210, and a second through hole 2211 is provided on the guide member 221. In order to assemble and fix the valve core armature 210 and the guide member 221, it is necessary to axially position the valve core armature 210 and the guide member 221 so that the first through hole 211 and the second through hole 2211 can overlap, so that the fixing mechanism 150 can pass the fixing member through the through holes on the valve core armature 210 and the guide member 221 to assemble and fix the valve core armature 210 and the valve core assembly 220.

[0066] By way of example, the fixing member can be a pin structure of various types. For example, the fixing member can be set as a rigid metal pin or an elastic pin with elastic function. The elastic pin has a certain elastic deformation space and can provide corresponding elastic space for the assembly and fixation of the valve core armature 210 and the valve core assembly 220.

[0067] exist Figure 1 In the illustrated embodiment, the depth positioning and axial positioning between the valve core armature 210 and the valve core assembly 220 can be automatically achieved, thereby effectively improving the assembly accuracy of the valve core armature 210 and the valve core assembly 220, improving the quality stability of the assembled product while ensuring manual safety, improving work efficiency and being able to detect incoming materials to prevent errors.

[0068] Optionally, see Figure 2 , Figure 2 This is a schematic structural diagram of another assembly device provided in an embodiment of the present application. The mounting structure 130 may include: a fixing block 131 and a guide block 132 .

[0069] It should be noted that a first groove is provided on the fixed block 131, and a second groove is provided on the guide block 132, and the first groove and the second groove are arranged opposite to each other; the fixed block 131 and the guide block 132 are fixedly connected by a connecting piece 163, and the space area formed by the first groove and the second groove is used to accommodate the valve core armature 210. The mounting structure 130 for fixing the valve core armature 210 may include a corresponding fixed block 131 and a guide block 132, and two grooves are respectively provided on the fixed block 131 and the guide block 132, and the fixed block 131 and the guide block 132 are connected by the connecting piece 163 so that the two grooves can form a corresponding space area, and the space area fits with the outer surface of the valve core armature 210 to accommodate the valve core armature 210. Fixing the valve core armature 210 in an embedded manner effectively improves the stability of the valve core armature 210 during assembly.

[0070] Optionally, the first groove and the second groove can be set according to the outer surface shape and parameters of the valve core armature 210. For example, when the outer surface of the valve core armature 210 is a cylinder, the first groove and the second groove are both set to corresponding semicircular grooves; when the outer surface of the valve core armature 210 is a rectangular parallelepiped, the first groove and the second groove are both set to corresponding rectangular grooves, etc.

[0071] Optionally, in order to achieve stable assembly, a corresponding base plate 161 may be provided in the assembly device to carry multiple components. The base plate 161 may include multiple countersunk holes and through holes. The countersunk holes can be used to fix the baffle 162 structure used to fix the adjustment component 110 and the pressure component 120. A plurality of threaded holes may be provided on the baffle 162 structure to connect with the base plate 161. The baffle 162 structure may also be provided with through holes connected with the adjustment component 110, and a plurality of threaded holes for assembling the pressure component 120; the through holes can be used to connect the base plate 161 with the bottom support 164 to connect the overall assembly device with the press workbench.

The connectors 163 may include structures such as conical pins to connect the fixed block 131 with the guide block 132. Correspondingly, the guide block 132 may also be provided with corresponding countersunk holes to assemble the corresponding connectors 163 to achieve connection with the fixed block 131.

[0073] It should be noted that in order to support the adjustment component 110, the fixed block 131 may also include a corresponding support block 1311 structure. The support block 1311 may be provided with a corresponding plurality of threaded holes and groove structures. The shape of the groove structure matches the outer surface of the adjustment component 110. The threaded hole is used to connect with the base plate 161 to fix the support block 1311 on the base plate 161, thereby fixing the adjustment component 110 at a relative position of the base plate 161.

[0074] Optionally, the fixed block 131 is provided with a first through hole 1312, which is arranged perpendicular to the first plane where the first groove is located; the positioning assembly 140 is arranged at one end of the fixed block 131 away from the guide block 132, and the projection center of the positioning assembly 140 and the first through hole 1312 on the first plane coincides; the positioning assembly 140 is used to axially position and fix the valve core armature 210 and the guide member 221 through the first through hole 1312. Among them, the fixed block 131 and the positioning assembly 140 are arranged opposite to each other, and the fixed block 131 is provided with a first through hole 1312 for the positioning assembly 140 to pass through, and the first through hole 1312 is arranged perpendicular to the first plane where the first groove is located, so that the positioning assembly 140 can move perpendicular to the first plane. The projection centers of the positioning assembly 140 and the first through hole 1312 on the first plane coincide with each other, and are arranged at an end of the fixed block 131 away from the guide block 132, so that the positioning assembly 140 can pass through the first through hole 1312 normally in the working state to axially position and fix the valve core armature 210 and the guide member 221 in the valve core assembly 220.

[0075] It should be noted that the positioning assembly 140 may include an elastic member 141 and a positioning member 142; the elastic member 141 and the positioning member 142 are connected; the elastic member 141 is used to provide the positioning member 142 with an elastic force in the first direction A to enter the first through hole 1312; the elastic member 141 is also used to drive the positioning member 142 to move in a second direction opposite to the first direction A based on the fixing member; the positioning member 142 is used to pass through the first through hole 1312, as well as the first through hole 211 on the valve core armature 210 and the second through hole 2211 on the guide member 221. In order to perform corresponding movement in the first through hole 1312 to realize the axial positioning function, the positioning assembly 140 may include an elastic member 141 and a connected positioning member 142, one end of the elastic member 141 is fixed, and the other end is connected to the positioning member 142, so as to provide the positioning member 142 with an elastic force in the first direction A to enter the first through hole 1312, and when the valve core armature 210 and the valve core assembly 220 are fixed by the fixing member, in order not to affect the normal use of the fixing member, the elastic member 141 can also The positioning member 142 can be driven to move in a second direction opposite to the first direction A, that is, through the elastic deformation of the elastic member 141, the positioning member 142 is driven to reciprocate in the first through hole 1312, so that the positioning member 142 can pass through the first through hole 1312, the first through hole 211 on the valve core armature 210 and the second through hole 2211 on the guide member 221 to axially position the valve core armature 210 and the guide member 221, and automatically withdraw after completing the axial positioning to achieve subsequent assembly and fixation.

[0076] For example, the elastic member 141 may include a structure with elastic properties such as a spring, and the positioning member 142 may include a pin-shaped structure with relatively high hardness such as metal.

[0077] Optionally, the guide block 132 includes a second through hole 1321, which is arranged perpendicular to the first plane, and the projection centers of the second through hole 1321 and the first through hole 1312 on the first plane coincide with each other; the fixing mechanism 150 is arranged at one end of the guide block 132 away from the fixing block 131, and the projection centers of the fixing mechanism 150 and the second through hole 1321 on the first plane coincide with each other; the fixing mechanism 150 is used to drive the fixing member to pass through the valve core armature 210 and the guide member 221 based on the second through hole 1321. The guide block 132 is arranged opposite to the fixing mechanism 150, and the guide block 132 is provided with a second through hole 1321 for the fixing mechanism 150 to pass through and corresponding to the first through hole 1312, so as to guide the movement of the fixing mechanism 150 through the second through hole 1321. The fixing structure 114 is arranged at one end of the guide block 132 away from the fixing block 131, so that the fixing mechanism 150 can drive the connected fixing member to pass through the second through hole 1321 normally under normal working conditions, and assemble and fix the guide member 221 in the valve core armature 210 and the valve core assembly 220.

[0078] Optionally, see Figure 3 , Figure 3 A structural schematic diagram of a fixing mechanism provided in an embodiment of the present application, the fixing mechanism 150 may include: a pressure structure, a connecting structure 151 and a punch needle 152; the connecting structure 151 connects the pressure structure and the punch needle 152; the pressure structure is used to provide the connecting structure 151 and the punch needle 152 with a downward pressure perpendicular to the second through hole 1321 and directed toward the valve core armature 210; the punch needle 152 is used to connect the fixing piece, and based on the downward pressure, drives the fixing piece to pass through the second through hole 1321, the first through hole 211 on the valve core armature 210, and the second through hole 2211 on the guide piece 221.

[0079] In order to perform corresponding movement in the second through hole 1321 to realize the automatic assembly and fixing function, the fixing mechanism 150 may include a pressure structure, a connecting structure 151 and a punching needle 152. The connecting structure 151 connects the pressure structure and the punching needle 152. The pressure structure can provide the connecting structure 151 and the punching needle 152 with a downward pressure perpendicular to the second through hole 1321 and directed to the valve core armature 210. The punching needle 152 can be connected to the set fixing member to drive the fixing member to pass through the second through hole 1321, the first through hole 211 on the valve core armature 210 and the second through hole 2211 on the guide member 221 based on the downward pressure, so as to assemble and fix the valve core armature 210 and the guide member 221. The valve core armature 210 and the valve core assembly 220 can be automatically assembled and fixed after being axially positioned and aligned, which effectively improves the assembly efficiency.

[0080] Optionally, the pressure structure can be set as a corresponding pneumatic press, and the connector 163 can be set as a connector for power connection between the pneumatic press and the punch 152. The connector can be designed with an external step for connecting the pneumatic press, and a countersunk hole can be provided in the connector for connecting the punch 152. The punch 152 can be set as a corresponding metal structure, such as a stainless steel punch. The unchamfered end of the punch 152 cooperates with the hole in the connector and can be fixed with two hexagonal cone-end set screws. After the punch 152 and the connector are assembled, the connector is connected to the main shaft of the pneumatic press using bolts or the like.

[0081] Optionally, see Figure 4 , Figure 4A schematic diagram of the structure of an adjustment component provided in an embodiment of the present application, the adjustment component 110 may include: a housing 111 and an adjustment member 112. The outer surface of the housing 111 is provided with a thread, and the adjustment member 112 is sleeved on the outer surface of the housing 111, and the adjustment member 112 is used to adjust the position of the guide member 221 inside the valve core armature 210 based on the rotation with the thread. Among them, since the pressure component 120 provides a relatively constant power, and for different types of electromagnetic baffle 162 valves, the specific target positions of the valve core armature 210 and the valve core component 220 when performing depth positioning are different, therefore, the adjustment component 110 can be used to further adjust the position of the guide member 221 inside the valve core armature 210 after the pressure component 120 provides the corresponding constant power. The adjusting component 110 includes a shell 111 and an adjusting member 112. The adjusting member 112 is sleeved on the outer surface of the shell 111 through a threaded sleeve arranged on the outer surface of the shell 111, so that the adjusting member 112 can adjust the position of the guide member 221 inside the valve core armature 210 based on the selection of the thread, thereby achieving high-precision depth positioning, and is suitable for adjusting a variety of different types of valve core assemblies 220, effectively improving the application range of the assembly device.

[0082] For example, the adjustment member 112 may include one or more wire loop structures ( Figure 4 Only two are shown, and the other numbers are not shown), the threads inside the wire coil structure are matched with the threads on the surface of the shell 111, so that the length of the adjustment component 110 can be adjusted by rotating the wire coil, thereby adjusting the position of the guide member 221 deep into the valve core armature 210.

[0083] Optionally, since the valve core assembly 220 and the valve core armature 210 need to be axially positioned when they are assembled and fixed, the guide member 221 in the valve core assembly 220 can be rotated during the axial positioning so that the guide member 221 can be aligned with the valve core armature 210 in the axial direction. In order to adapt to the rotation of the valve core assembly 220, the adjustment assembly 110 can also include a rotating structure 113. The rotating structure 113 is arranged at the second end of the housing 111 away from the adjusting member 112. The rotating structure 113 is arranged to fit the base flange surface of the valve core assembly 220 when it is working. The rotating structure 113 is used to rotate based on the rotation of the valve core assembly 220. Among them, the rotating structure 113 is arranged on the second end of the shell 111 away from the adjusting member 112. The rotating structure 113 can be arranged in a fit with the base flange surface of the valve core assembly 220 under working conditions, and can rotate based on the rotation of the valve core assembly 220, that is, the rotating assembly can be driven by the valve core assembly 220 to rotate, so as to achieve axial adjustment of the valve core assembly 220 while fixing the valve core assembly 220, thereby improving the effectiveness and stability of axial positioning.

[0084] Exemplarily, a corresponding stepped structure can be provided inside the second end of the housing 111 to assemble the installed rotating structure 113. A corresponding fixing structure 114 can also be provided inside the first end of the housing 111. The fixing structure 114 can include structures such as screws and nuts to connect the housing 111 with the baffle 162, thereby connecting the adjusting assembly 110 with the pressure assembly 120.

[0085] Optionally, the rotating structure 113 can include a rotating flange surface 1131 and a rotating shaft 1132. The rotating flange surface 1131 is connected to the rotating shaft 1132. The rotating flange surface 1131 is arranged in contact with the base flange surface during operation. The rotating shaft 1132 is used to provide a rotating space for the rotating flange surface 1131. Among them, the rotating structure 113 includes a rotating flange surface 1131 that can be arranged in contact with the base flange surface during operation. The rotating flange surface 1131 can be driven by the base flange surface to rotate. In order to realize the rotating function of the rotating flange surface 1131, a corresponding rotating shaft 1132 can be provided to provide a corresponding rotating space for the rotating flange surface 1131.

[0086] It should be noted that the material hardness of the rotating flange surface 1131 is d1, and the material hardness of the base flange surface is d2, where d1 < d2. The material hardness of the rotating flange surface 1131 is lower than that of the base flange surface to reduce adverse effects such as wear on the base flange surface caused by friction between the two flange surfaces, that is, to reduce adverse effects on the spool assembly 220 when the adjusting assembly 110 contacts the spool assembly 220 during operation.

[0087] Exemplarily, the rotating shaft 1132 can be set as a shaft structure such as a corresponding deep groove ball bearing, and the rotating flange surface 1131 can be set as a structure such as a corresponding rotating base. When performing axial positioning, the spool armature 210 can be rotated first so that the positioning component 140 at the bottom can pass through the first through hole 211 on the spool armature 210, and then the guide member 221 can be rotated, thereby driving the rotating flange surface 1131 and the rotating shaft 1132 in rotational contact to rotate. When the second through hole 2211 of the guide member 221 rotates to the position corresponding to the positioning component 140, the positioning component 140 passing through the first through hole 211 on the spool armature 210 can continue to pass through the second through hole 2211, thereby realizing the axial positioning of the spool armature 210 and the guide member 221.

[0088] It should be noted that in the process of assembling the assembly device, the screws, nuts, washers and other fixings used can be set and adjusted according to the actual situation and specific needs, and there is no restriction on them. During assembly, the positioning assembly 140 and the fixing block 131 can be assembled first, and then the fixing block 131 can be connected to the bottom plate 161, the baffle 162 can be connected to the bottom plate 161, and the pressure assembly 120 and the adjustment assembly 110 can be fixed on the baffle 162. The guide block 132 is fixed on the fixing block 131, so as to determine the setting position of the fixing mechanism 150 and complete the assembly.
