Description

Technical Field

[0001] This application relates to the technical field of device assembly. Specifically, it relates to an assembly device and an assembly method. Background Art

[0002] Threaded connections are widely used in mechanical engineering. Due to the characteristics of threads, when a component rotates one full circle (360°), there is only a small displacement of one pitch in the axial direction. Therefore, it is commonly used in devices with high-precision adjustment requirements in instruments and meters. For example, in a pressure switch, a threaded connection is usually used, taking advantage of the small pitch of the thread to adjust the position fixed by the disc spring, so as to adjust the compression amount of the disc spring in the axial direction by adjusting the position fixed by the disc spring.

[0003] Since some of the parts of the pressure switch have small product sizes and small inner cavity spaces, and the trigger stroke of the corresponding micro switch used is also very small. In the currently commonly used glue-pointing fixing method, during the glue-pointing and rotation processes, since the disc spring fixing is in a free state, and there is a tooth gap between the thread of the disc spring fixing and the inner cavity wall of the pressure switch, the position of the precisely adjusted disc spring fixing is likely to shift during the fixing process, resulting in a difference between the actual position and the fine-tuning position of the disc spring fixing, which has an adverse impact on the control accuracy of the pressure switch, affects the set value of the finely adjusted pressure switch, and cannot meet the current high-precision usage requirements. Summary of the Invention

[0004] In view of this, the purpose of the embodiments of this application is to provide an assembly device and an assembly method to improve the problem of poor fixing position accuracy of the disc spring fixing existing in the prior art.

[0005] To solve the above problems, in a first aspect, the embodiments of this application provide an assembly device, which includes: an adjusting member, a fastening member, and a rotating member;

[0006] The fastening member is used to be fixed on the switch cavity to be assembled. The adjusting member passes through the fastening member and is arranged inside the switch cavity. The first end of the adjusting member is in contact connection with the fixing member to be assembled, and the second end of the adjusting member is connected to the rotating member; wherein, the inner wall of the switch cavity and the outer wall of the fixing member are connected by threads;

[0007] The rotating member is used to adjust the height position of the adjusting member in the axial direction by rotation; wherein, the axial direction is the elastic change direction of the elastic member restricted by the fixing member;

[0008] The fastening member is used to apply pressure to the adjusting member in the axial direction and pointing to the fixing member;

[0009] The adjusting member is configured to drive the fixing member to a target fixing position based on the height position, and fix the fixing member at the target fixing position based on the pressure.

[0010] In the above implementation process, the assembly device includes a fastener fixed on the switch cavity to be assembled to improve the stability during the assembly process, an adjusting member passing through the fastener and in contact connection with the fixing member to be assembled, and a rotating member connected to the adjusting member. The adjusting member can be rotated by the rotating member, and by rotating in the radial direction, the height position of the adjusting member in the axial direction can be changed. Since the outer wall of the fixing member is threadedly connected to the inner wall of the switch cavity, the adjusting member can drive the fixing member to rotate synchronously. The height change of the adjusting member can change the position of the fixing member in the axial direction until the fixing member reaches the ideal target fixing position. And, since the fastener can apply a pressure pointing to the fixing member in the axial direction based on the adjusting member, when the target fixing position is reached, the fixing member can also be fixed at the target fixing position based on this pressure to reduce the adverse situation of the position deviation of the fixing member in the axial direction due to the tooth clearance of the thread, effectively improving the position accuracy when the fixing member is fixed, thereby improving the stroke accuracy of the elastic member restricted by the fixing member, and further improving the control accuracy of the pressure switch controlled by the elastic member, meeting various current high-precision usage requirements.

[0011] Optionally, a first end of the adjusting member is provided as a protruding member corresponding to the groove shape on the fixing member;

[0012] The protruding member is configured to match the groove on the fixing member, and the protruding member is used to drive the fixing member to move.

[0013] In the above implementation process, a groove is provided on the fixing member, and a first end of the adjusting member is provided as a protruding member corresponding to the groove shape on the fixing member, so that through the cooperation between the protruding member and the groove, the adjusting member drives the fixing member to perform synchronous rotational movement, effectively improving the synchronism of the movement between the adjusting member and the fixing member.

[0014] Optionally, the assembly device further includes: an annular elastic member;

[0015] A middle section between the first end and the second end of the adjusting member is provided as a cylindrical structure;

[0016] The annular elastic member is disposed around the middle section, a position of a first end of the annular elastic member is restricted by the fastener, and a position of a second end of the annular elastic member is restricted by the protruding member in the adjusting member;

[0017] The fastener applies the pressure pointing to the fixing member in the axial direction to the adjusting member based on the annular elastic member.

[0018] In the above implementation process, the middle section between the first end and the second end of the adjusting member can be set as a cylindrical structure to facilitate the rotational movement of the adjusting member. The assembly device may further include an annular elastic member surrounding the middle section. The position of the first end of the annular elastic member is restricted by a fastener on the switch cavity, and the position of the second end is restricted by a protrusion on the second end of the adjusting member, so as to apply a pressure in the axial direction towards the fixing member to the adjusting member through the fixed fastener based on the compressed annular elastic member with both ends restricted. It is possible to apply pressure to the fixing member by restricting the annular elastic member, so as to reduce the adverse situation of the position deviation of the fixing member in the fixing direction due to the tooth clearance of the thread, and effectively improve the position accuracy when the fixing member is fixed.

[0019] Optionally, the assembly device further includes: a restricting member;

[0020] The restricting member is disposed around one end of the middle section close to the protrusion;

[0021] The restricting member is used to restrict the second end of the annular elastic member.

[0022] In the above implementation process, considering the differences in the acting forces applied by elastic members of different models to the fixing member, in order to reduce the position deviation of the fixing member in the axial direction, it is necessary to apply different magnitudes of pressure to the fixing member according to the actual situation. Therefore, the assembly device may further include a restricting member disposed around one end of the middle section close to the protrusion, so as to further restrict the second end of the annular elastic member through the restricting member, thereby adjusting the compression condition of the annular elastic member, and adjusting the magnitude of the pressure applied to the fixing member according to different compression conditions, further reducing the position deviation of the fixing member in the axial direction due to the acting force situation, and being applicable to the assembly of fixing members corresponding to a variety of different types of elastic members.

[0023] Optionally, the number of the restricting members is determined based on the elastic parameters of the elastic member.

[0024] In the above implementation process, since different elastic members corresponding to the fixing member require different magnitudes of pressure to fix the position, the number of the restricting members provided can be determined according to the elastic parameters of the elastic member, so as to adjust the compression condition of the annular elastic member through different numbers of restricting members, provide the pressure required for fixing for the fixing members corresponding to different models of elastic members, and be applicable to the assembly of fixing members corresponding to a variety of different types of elastic members.

[0025] Optionally, the fastener includes: a fixed seat, a connecting member, and a locking member;

[0026] The fixed seat is configured to have an inner diameter matching the outer wall of the switch cavity, and the locking member is used to surround and fix the fixed seat on the outer wall of the open end of the switch cavity;

[0027] The connecting member is fixedly arranged on the fixed seat, and a through hole is arranged on the connecting member, and the through hole is used to accommodate the middle section to pass through.

[0028] In the above implementation process, the fastener may include a fixed seat, a connecting member and a locking member. The fixed seat is configured to have an inner diameter matching the outer wall of the switch cavity, so as to surround and fix the fixed seat on the outer wall of the open end of the switch cavity through the locking member. The connecting member is fixedly arranged on the fixed seat, and a through hole for the middle section of the adjusting member to pass through is arranged on the connecting member, so as to provide a stable working environment for the adjusting member through the fastener, and limit the first end of the annular elastic member, and apply a pressure pointing to the fixing member to the adjusting member based on the annular elastic member through the fastener, so as to press the fixing member through the adjusting member and reduce the position offset of the fixing member in the axial direction.

[0029] Optionally, the second end of the adjusting member is arranged as a polygonal columnar structure;

[0030] The polygonal columnar structure is configured to match the inner wall of the connection hole of the rotating member.

[0031] In the above implementation process, in order to reduce the sliding of the adjusting member during rotation, the second end of the adjusting member connected to the rotating member may be arranged as a polygonal columnar structure, and the polygonal columnar structure matches the inner wall of the connection hole of the rotating member, so that the rotating member can drive the adjusting member to rotate through the cooperation between the polygonal columnar structure and the connection hole, and reduce the sliding displacement between the rotating member and the adjusting member, effectively improving the adjustment accuracy of the height position of the adjusting member.

[0032] In a second aspect, an embodiment of the present application further provides an assembly method, which is applied to the assembly device described in any one of the above first aspects, and the method includes:

[0033] Rotating the adjusting member of the assembly device through the rotating member of the assembly device to adjust the height position of the adjusting member in the axial direction; wherein, the axial direction is the elastic change direction of the elastic member restricted by the fixing member to be assembled;

[0034] Driving the fixing member to move to the target fixing position through the adjusting member based on the height position, and fixing the fixing member at the target fixing position based on the pressure applied in the axial direction pointing to the fixing member by the fastener of the assembly device.

[0035] In the above implementation process, the rotating member in the assembling device can rotate the adjusting member, so as to change the height position of the adjusting member in the axial direction through rotation in the radial direction. The adjusting member can drive the fixing member to rotate synchronously, so as to change the position of the fixing member in the axial direction based on the change of the height position until the fixing member reaches the ideal target fixing position. And, since the fastening member can apply a pressure pointing to the fixing member in the axial direction based on the adjusting member, therefore, in the case of reaching the target fixing position, the fixing member can also be fixed at the target fixing position based on this pressure, so as to reduce the adverse situation of the position deviation of the fixing member in the axial direction caused by the tooth clearance of the thread, effectively improving the position accuracy when the fixing member is fixed, thereby improving the stroke accuracy of the elastic member restricted by the fixing member, and further improving the control accuracy of the pressure switch controlled by the elastic member, meeting various current high-precision usage requirements.

[0036] Optionally, the method further includes:

[0037] Determine the target fixing position of the fixing member according to the compression requirement and elastic parameter of the elastic member in the switch cavity;

[0038] Based on the target fixing position and the thread parameter between the fixing member and the switch cavity, determine the direction and driving force when the rotating member rotates.

[0039] In the above implementation process, the compression performance and elastic parameters of the elastic member restricted by the fixing member can be determined according to the actual situation of the switch, and the target fixing position of the fixing member in the ideal situation can be determined based on the compression performance and elastic parameters of the elastic member. Then, according to the target fixing position and the thread parameter between the fixing member and the switch cavity, the required rotation condition of the fixing member can be determined, so as to determine the direction and driving force when the rotating member rotates. It is possible to determine the ideal target fixing position of the fixing member according to the actual situation of the elastic member, and determine the working condition of the rotating member according to the target fixing position and the actual situation during rotation, effectively reducing the time and adjustment cost required for repeatedly determining the position during assembly, and improving the efficiency and accuracy during assembly.

[0040] Optionally, the method further includes:

[0041] Fix the fixing member fixed at the target fixing position on the switch cavity through a curing process.

[0042] In the above implementation process, in order to further improve the position accuracy of the fixing member, when the fixing member moves and is fixed at the ideal target fixing position based on the assembly device, the fixing member can be cured to fix it at the target fixing position in the case where the assembly device is about to be removed, thus completing the entire assembly process. The fixing process after assembly can be further completed through curing treatment, effectively improving the effectiveness of fixing the fixing member at the target fixing position.

[0043] In summary, the embodiments of the present application provide an assembly device and an assembly method, which can reduce the adverse situation of the position deviation of the fixing member in the axial direction due to the tooth clearance of the thread, effectively improve the position accuracy when the fixing member is fixed, thereby improving the stroke accuracy of the elastic member restricted by the fixed member, and further improving the control accuracy of the pressure switch controlled by the elastic member, meeting various current high-precision usage requirements.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0050] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope protected by the embodiments of the present application.

[0051] In the existing pressure switch structure, since the product sizes of some parts of the pressure switch are small, the inner cavity space is also small. For example, the inner cavity diameter of some pressure switches is less than 50 mm, etc. Correspondingly, the development stroke set in the inner cavity is also very small. For example, the trigger stroke of the micro switch is within 0.05 mm, etc. In the currently commonly used glue-dotting fixing method, during the glue-dotting and rotating processes, since the disc spring fixing is in a free state, and since there is a tooth gap in the thread between the disc spring fixing and the inner cavity wall of the pressure switch, the position of the precisely adjusted disc spring fixing is prone to shift during the fixing process. For example: due to the thread characteristics, when the thread is assembled and screwed in, the inner and outer threads mesh with the lower thread line. If impacted, the inner and outer threads mesh with the upper thread line, that is, it moves by one tooth gap. The tooth gap of the thread with detachable and adjustable functions is inevitable. However, the tooth gap will affect the precision of precise adjustment. Especially for the thread adjustment components with very high precision requirements, the tooth gap directly affects the compression amount of the disc spring, resulting in a difference between the actual position and the fine-tuning position of the disc spring fixing, thereby having an adverse impact on the control precision of the pressure switch, affecting the set value of the fine-tuned pressure switch, and being unable to meet the current high-precision use requirements.

[0052] To solve the above problems, the embodiments of the present application provide an assembly device and an assembly method, which can reduce the adverse situation of the position shift of the fixing part in the axial direction due to the tooth gap of the thread, effectively improve the position precision during the fixing of the fixing part, thereby improving the stroke precision of the elastic part restricted by the fixed part, and further improving the control precision of the pressure switch controlled by the elastic part, meeting the current various high-precision use requirements.

[0053] Please refer to Figure 1 , Figure 1 , which is a schematic cross-sectional structure diagram of an assembly device provided by an embodiment of the present application. The assembly device may include: an adjusting part 110, a fastening part 120, and a rotating part 130.

[0054] Among them, the fastening part 120 is used to be fixed on the switch cavity A1 to be assembled. The adjusting part 110 passes through the fastening part 120 and is arranged inside the switch cavity A1. The first end of the adjusting part 110 is in contact connection with the fixing part A2 to be assembled, and the second end of the adjusting part 110 is connected to the rotating part 130.

[0055] It should be noted that the inner wall of the switch cavity A1 is threadedly connected to the outer wall of the fixing member A2. During assembly, the position of the fixing member A2 is adjusted by the assembly device. The assembly device includes a fastener 120 fixed to the switch cavity A1 to be assembled to improve the stability during the assembly process, an adjusting member 110 disposed through the fastener 120 and in contact connection with the fixing member A2 to be assembled, and a rotating member 130 connected to the adjusting member 110. Optionally, the adjusting member 110 can be set as various devices capable of driving the fixing member A2 to rotate together, such as a Y-shaped structure. The fastener 120 is various components with a fixing function, such as a fixing table, etc. The rotating member 130 is various devices capable of providing a rotating function, such as a torque wrench with torque adjustment and fixed value functions, etc.

[0056] Optionally, the elastic member A3 can be an elastic switch trigger such as a disc spring. The center of the elastic member A3 can be connected to the moving shaft provided in the switch cavity A1 so that the elastic member A3 can generate elastic changes along the moving shaft based on the change of the gas in the chamber on the side away from the fixing member A2. The fixing member A2 can be an annular member matching the edge shape of the disc spring to place structures such as a micro switch triggered by the elastic member A3 in the hollow area of the annular member. For example, when the elastic member A3 is a circular disc spring, the fixing member A2 can be set as an annular fixing member A2 matching the outer size of the circular disc spring to limit the elastic deformation of the elastic member A3.

[0057] Among them, the rotating member 130 is used to adjust the height position of the adjusting member 110 in the axial direction F by rotation. The axial direction F is the elastic change direction of the elastic member A3 restricted by the fixing member A2, that is, the position direction that can be adjusted by the fixing member A2 through rotation. The fastening member 120 is used to apply a pressure to the adjusting member 110 in the axial direction F pointing to the fixing member A2. The adjusting member 110 is used to drive the fixing member A2 to move to the target fixing position based on the height position, and fix the fixing member A2 at the target fixing position based on the pressure. The adjusting member 110 can be rotated by the rotating member 130 to change the height position of the adjusting member 110 in the axial direction F through rotation in the radial direction. Since the outer wall of the fixing member A2 is threadedly connected to the inner wall of the switch cavity A1, the adjusting member 110 can drive the fixing member A2 to rotate synchronously. The height change of the adjusting member 110 can change the position of the fixing member A2 in the axial direction F until the fixing member A2 reaches the ideal target fixing position. And, since the fastening member 120 can apply a pressure to the fixing member A2 in the axial direction F based on the adjusting member 110, in the case of reaching the target fixing position, the fixing member A2 can also be fixed at the target fixing position based on this pressure to reduce the adverse situation of the position offset of the fixing member A2 in the axial direction F due to the tooth clearance of the thread, effectively improving the position accuracy when the fixing member A2 is fixed, thereby improving the stroke accuracy of the elastic member A3 restricted by the fixing member A2, and further improving the control accuracy of the pressure switch controlled by the elastic member A3, meeting various current high-precision usage requirements.

[0058] Optionally, please refer to Figure 2 , Figure 2 which is a three-dimensional structural schematic diagram of an assembly device provided by an embodiment of the present application.

[0059] Optionally, a plurality of grooves can be provided on the fixing member A2, and the plurality of grooves can be symmetrically distributed to improve the uniformity of the force on the fixing member A2. Correspondingly, the first end of the adjusting member 110 can be provided as a convex member 111 corresponding to the groove shape on the fixing member A2. The convex member 111 is configured to match the groove on the fixing member A2, and the convex member 111 is used to drive the fixing member A2 to move.

[0060] It should be noted that the number and distribution positions of the protrusion structures in the protrusion member 111 match the groove structures on the fixing member A2. For example, if there are 4 evenly distributed grooves on the fixing member A2, 4 evenly distributed protrusion structures can also be provided on the protrusion member 111. Moreover, the shape and depth of the protrusion structures also match the grooves. When assembling, the protrusion member 111 at the first end of the adjusting member 110 can be inserted into the groove on the fixing member A2, so that through the cooperation between the protrusion member 111 and the groove, the adjusting member 110 drives the fixing member A2 to perform synchronous rotational motion, effectively improving the synchronism of the motion between the adjusting member 110 and the fixing member A2.

[0061] Exemplarily, the protrusion member 111 can be set as a corresponding flat-square clearance structure, which can prevent affecting other components inside the switch cavity A1 during rotational motion.

[0062] Optionally, the assembling device can further include: an annular elastic member 140. Wherein, the middle section between the first end and the second end of the adjusting member 110 is set as a cylindrical structure, and the annular elastic member 140 is arranged around the middle section. The position of the first end of the annular elastic member 140 is restricted by the fastener 120, and the position of the second end of the annular elastic member 140 is restricted by the protrusion member 111 in the adjusting member 110. The fastener 120 applies a pressure in the axial direction F towards the fixing member A2 to the adjusting member 110 based on the annular elastic member 140. The middle section between the first end and the second end of the adjusting member 110 can be set as a cylindrical structure to facilitate the rotational motion of the adjusting member 110. The assembling device can also include the annular elastic member 140 surrounding the middle section. The position of the first end of the annular elastic member 140 is restricted by the fastener 120 fixed on the switch cavity A1, and the position of the second end is restricted by the protrusion member 111 at the second end of the adjusting member 110, so that through the fixed fastener 120, based on the compressed annular elastic member 140 with both ends restricted, a pressure in the axial direction F towards the fixing member A2 is applied to the adjusting member 110. The adverse situation of the position deviation of the fixing member A2 caused by the tooth clearance of the thread in the fixing direction can be reduced by restricting the annular elastic member 140, effectively improving the position accuracy when the fixing member A2 is fixed.

[0063] Exemplarily, the annular elastic member 140 can be set as a device such as a cylindrical spring. In the axial direction F, the annular elastic member 140 generates elastic deformation based on the position restrictions at both ends, so that the fastener 120 can apply a pressure towards the fixing member A2 to the adjusting member 110 based on the annular elastic member 140.

[0064] Optionally, considering the differences in the forces exerted by elastic members A3 of different models on the fixing member A2, in order to reduce the position offset of the fixing member A2 in the axial direction F, different magnitudes of pressure need to be applied to the fixing member A2 according to the actual situation. Therefore, the assembly device may further include: a limiting member 141. The limiting member 141 is disposed around one end of the middle section close to the protruding member 111, and the limiting member 141 is used to limit the second end of the annular elastic member 140. The second end of the annular elastic member 140 can be further restricted by the limiting member 141, so as to adjust the compression of the annular elastic member 140, and according to different compression conditions, adjust the magnitude of the pressure applied to the fixing member A2, further reducing the position offset of the fixing member A2 in the axial direction F due to the force situation, and is applicable to the assembly of the fixing member A2 corresponding to a variety of different types of elastic members A3.

[0065] It should be noted that, for the convenience of assembly, the limiting member 141 is disposed at one end of the middle section close to the protruding member 111. In some other angular assembly scenarios, the limiting member 141 can also be disposed at one end of the middle section close to the fastening member 120, and the specific placement position of the limiting member 141 can be set according to the actual situation.

[0066] Exemplarily, the limiting member 141 can be set as an annular gasket structure, and the inner ring of the gasket is determined based on the outer wall parameters of the middle section, so that the gap between the inner ring of the gasket and the middle section is small, reducing the adverse situation that the annular elastic member 140 is stuck in the gap.

[0067] Optionally, a corresponding groove area can also be provided at one end of the limiting member 141 in contact with the annular elastic member 140. The groove area matches the shape and size of the annular elastic member 140, so that when the limiting member 141 contacts the annular elastic member 140, the annular elastic member 140 can be located within the groove area, and the movement direction of the annular elastic member 140 is restricted by the limiting member 141, reducing the adverse situation that the annular elastic member 140 deviates in other directions.

[0068] Optionally, since different fixing members A2 corresponding to different elastic members A3 require different magnitudes of pressure to fix the position, the number of limiting members 141 is determined based on the elastic parameters of the elastic member A3, so as to adjust the compression of the annular elastic member 140 through different numbers of limiting members 141, and provide the pressure required for fixing for the fixing member A2 corresponding to different models of elastic members A3, and is applicable to the assembly of the fixing member A2 corresponding to a variety of different types of elastic members A3.

[0069] Exemplarily, the elastic parameters of the elastic member A3 can include parameters such as elastic potential energy and elastic force magnitude, so as to determine the magnitude of the pressure to be applied according to the elastic parameters of the elastic member A3, then determine the compression of the annular elastic member 140 according to the magnitude of the pressure, and determine the number of limiting members 141.

[0070] Optionally, the fastener 120 may include a fixing base 121, a connecting member 122, and a locking member 123. The fixing base 121 is configured to have an inner diameter matching the outer wall of the switch cavity A1. The locking member 123 is used to surround and fix the fixing base 121 on the outer wall of the open end of the switch cavity A1. The connecting member 122 is fixedly arranged on the fixing base 121, and a through hole is provided on the connecting member 122 for the middle section to pass through. The fixing base 121 is configured to have an inner diameter matching the outer wall of the switch cavity A1, so as to surround and fix the fixing base 121 on the outer wall of the open end of the switch cavity A1 through the locking member 123. The connecting member 122 is fixedly arranged on the fixing base 121, and a through hole for the middle section of the adjusting member 110 to pass through is provided on the connecting member 122, so as to provide a stable working environment for the adjusting member 110 through the fastener 120, and limit the first end of the annular elastic member 140. The fastener 120 applies a pressure towards the fixing member A2 to the adjusting member 110 based on the annular elastic member 140, so as to press the fixing member A2 through the adjusting member 110 and reduce the position offset of the fixing member A2 in the axial direction F.

[0071] Exemplarily, in order not to affect the inner cavity assembly, the fixing base can be set as a corresponding annular structure, and the locking member 123 can be set as a corresponding locking screw or other devices. An internal thread matching the thread on the surface of the locking screw is provided on one side of the annular structure, so as to fix the fixing base 121 on the switch cavity A1 through the locking member 123.

[0072] Exemplarily, the connecting member 122 can be set as a rod-shaped structure fixed on the surface of the annular member and passing through the inner cavity area of the switch cavity A1. A through hole matching the outer wall of the middle section of the adjusting member 110 is provided in the central area of the rod-shaped structure, so that the adjusting member 110 can pass through the through hole normally for assembly and disassembly.

[0073] Optionally, in order to reduce the sliding condition when the adjusting member 110 rotates, the second end of the adjusting member 110 can be set as a polygonal columnar structure 112, and the polygonal columnar structure 112 is configured to match the inner wall of the connection hole of the rotating member 130. So that the rotating member 130 can drive the adjusting member 110 to rotate through the cooperation between the polygonal columnar structure 112 and the connection hole, and reduce the sliding displacement between the rotating member 130 and the adjusting member 110, effectively improving the adjustment accuracy of the height position of the adjusting member 110.

[0074] It should be noted that the diameter of the circumscribed circle of the polygonal columnar structure 112 is less than or equal to the cross-sectional diameter of the middle section, so that the adjusting member 110 can pass through the through hole of the connecting member 122 normally to achieve normal assembly and disassembly.

[0075] Exemplarily, the polygonal columnar structure 112 can be a wrench position structure such as a corresponding quadrilateral columnar structure, a pentagonal columnar structure, etc. Correspondingly, the connection holes of the rotating member 130 can also be set as rectangular holes, pentagonal holes, etc.

[0076] Optionally, after installing the elastic member A3 and the fixing member A2 into the switch cavity A1, the limiting member 141 can be first sleeved on the middle section of the adjusting member 110, and then the annular elastic member 140 can be sleeved on the middle section of the adjusting member 110. Then, the protruding member 111 of the adjusting member 110 is passed through the groove of the fixing member A2, the through hole of the connecting member 122 is passed through the adjusting member 110, the fixing seat 121 is sleeved on the switch cavity A1, the locking member 123 is assembled to the fixing seat 121 while locking the fixing seat 121 and the switch cavity A1, and then the rotating member 130 is sleeved on the second end of the adjusting member 110 to complete the assembly of the entire assembly device.

[0077] In the assembly device provided by the embodiment of the present application, the design of the fixing seat 121 and the locking member 123 provides an effective supporting surface for the annular elastic member 140. The limiting member 141 can make the compression deformation amount of the annular elastic member 140 controllable, realizing the controllability of the axial pressure on the fixing member A2. The number of the limiting members 141 can be increased or decreased according to the reaction force of the elastic member A3 on the fixing member A2, so as to adjust the magnitude of the axial pressure on the fixing member A2. The design of the adjusting member 110 enables the fixing member A2 to be stably fixed at any position in the axial direction F, and at the same time has the function of rotational adjustment. The design of the rotating member 130 makes the adjustment target visible, weakens the assembly and adjustment difficulty, improves the assembly and adjustment efficiency, and at the same time has a simple overall structure, convenient operation, and is convenient for batch production and use.

[0078] Please refer to Figure 3 , Figure 3 which is a schematic flow chart of an assembly method provided by an embodiment of the present application. This method is applied to the assembly device provided by the embodiment of the present application, and this method may include steps S200 - S300.

[0079] Step S200, rotate the adjusting member of the assembly device through the rotating member of the assembly device to adjust the height position of the adjusting member in the axial direction.

[0080] Wherein, the axial direction is the elastic change direction of the elastic member restricted by the fixing member to be assembled. The position direction that the fixing member can be adjusted by rotation can rotate the adjusting member through the rotating member in the assembly device, so as to change the height position of the adjusting member in the axial direction through rotation in the radial direction.

[0081] Step S300, drive the fixing member to move to the target fixing position based on the height position by the adjusting member, and fix the fixing member at the target fixing position based on the pressure applied in the axial direction and pointing to the fixing member by the fastener of the assembly device.

[0082] Among them, the adjusting member can drive the fixing member to rotate synchronously, so as to change the position of the fixing member in the axial direction based on the change of the height position until the fixing member reaches the ideal target fixing position. And, since the fastening member can apply a pressure pointing to the fixing member in the axial direction based on the adjusting member, therefore, when reaching the target fixing position, the fixing member can also be fixed at the target fixing position based on this pressure.

[0083] In Figure 3 the illustrated embodiment, the adverse situation of the position deviation of the fixing member in the axial direction caused by the tooth clearance of the thread can be reduced, effectively improving the position accuracy when the fixing member is fixed, thereby improving the stroke accuracy of the elastic member restricted by the fixing member, and further improving the control accuracy of the pressure switch controlled by the elastic member, meeting various current high-precision usage requirements.

[0084] Optionally, please refer to Figure 4 , Figure 4 which is a schematic flowchart of another assembly method provided by the embodiment of the present application, and this method may further include steps S410-S420.

[0085] Step S410, determine the target fixing position of the fixing member according to the compression requirement and elastic parameters of the elastic member in the switch cavity.

[0086] Among them, the compression performance and elastic parameters of the elastic member restricted by the fixing member can be determined according to the actual situation of the switch, and the target fixing position of the fixing member in the ideal situation can be determined based on the compression performance and elastic parameters of the elastic member.

[0087] Optionally, the trigger stroke of switch components such as microswitches arranged in the switch cavity can be determined first, and then the compression requirement of the elastic member can be determined according to the trigger stroke and combined with the elastic parameters of the elastic member, so as to determine the initial position of the elastic member according to the elastic parameters and compression requirement, and thus determine the target fixing position of the fixing member that restricts the position of the elastic member based on the initial position.

[0088] Step S420, determine the direction and driving force when the rotating member rotates based on the target fixing position and the thread parameters between the fixing member and the switch cavity.

[0089] Among them, the required rotation condition of the fixing member can be determined according to the target fixing position and the thread parameters between the fixing member and the switch cavity, so as to determine the direction and driving force when the rotating member rotates.

[0090] Optionally, since the fixing member changes its position in the axial direction based on rotation, the rotation situation of the fixing member when it rotates to the target fixing position can be determined according to the target fixing position and in combination with the thread parameters between the fixing member and the switch cavity. The rotation situation can include various data such as the rotation direction, the number of rotation turns, and the rotation force value. Thus, the direction and driving force of the rotating member during rotation can be determined from the rotation situation.

[0091] Exemplarily, the rotating member can be set as a fixed-torque wrench. Before use, the torque value of the fixed-torque wrench, that is, the driving force, can be set. The adjusting member is rotated with the fixed-torque wrench. When the torque reaches the set value of the fixed-torque wrench, the precise adjustment is completed. Then, the fixed-torque wrench is disassembled to complete the subsequent solidification process.

[0092] Exemplarily, the set value of a certain pressure switch is 400 Torr. After calculation and experiment, the fixed-torque wrench needs to provide a torque of 0.3 N·m, that is, the driving force. After the assembly device is assembled, the fixed torque of the fixed-torque wrench is set to 0.3 N·m. The adjusting member is rotated with the fixed-torque wrench. When it reaches 0.3 N·m, the fixing member has moved to the corresponding target fixing position.

[0093] In Figure 4 the embodiment of, the ideal target fixing position of the fixing member can be determined according to the actual situation of the elastic member, and the working situation of the rotating member can be determined according to the target fixing position and the actual situation during rotation, effectively reducing the time and adjustment cost required for repeatedly determining the position during assembly, and improving the efficiency and accuracy during assembly.

[0094] It should be noted that, in order to further improve the position accuracy of the fixing member, when the fixing member moves and is fixed at the ideal target fixing position based on the assembly device, the fixing member fixed at the target fixing position can be fixed on the switch cavity through a curing process to complete the entire assembly process.

[0095] Optionally, the curing process can include: passing through the inside of the switch cavity through a structure such as a dropper, applying a fixing glue at the connection between the fixing member and the inner wall of the switch cavity, and after waiting for the fixing glue to dry, the adjusting member can be disassembled to achieve the precise fixing of the fixing member.
