Description

Technical Field

[0001] This invention belongs to the field of micro switch assembly technology, specifically relating to an integrated tooling and method for fixing and testing micro switches. Background Technology

[0002] Existing technologies utilize a microswitch control structure, such as Figure 1 As shown, the structure mainly includes a base 30, a connector 80 with a curved surface control structure, a micro switch 40, a base plate 50 for fixing the micro switch 40, and a protective cover 60. The connector 80 includes a connector body 830 and a trigger seat 810 disposed on the connector body 830. In this micro switch control structure, the micro switch 40, the base plate 50, and the protective cover 60 form a complete assembly, thereby fixing the assembly on the mounting platform 330 of the base 30. Whether the switching action of the micro switch 40 can be accurately controlled is related to whether subsequent commands can be executed normally, and whether the micro switch 40 can be correctly triggered depends on whether the assembly position of the micro switch 40 on the mounting platform 330 is accurate.

[0003] The method by which the connector triggers the micro switch button switch is as follows: When the connector 80 is subjected to a certain impact force and pops out of the base 30 (see direction A) Figure 1 As shown), the curved structure on the connector 80 housing compresses the button 410 of the micro switch 40, controlling the travel of the micro switch button 410 and thus turning the pins of the micro switch 40 on and off; the trigger surface 810 on the trigger seat 810 of the connector 80 that controls the trigger of the micro switch button 410 faces away from the central axis of the connector, see... Figure 1 As shown.

[0004] The outward-facing curved structure of the trigger seat 810 on the connector 80 housing in the figure can precisely control the on / off state of the micro switch 40, and the fixed position of the micro switch 40 plays a key role. However, due to the tolerances of the microswitch 40 structure and its fixed position, the method of determining the fixed position of the microswitch 40 solely by structural limits cannot accurately control the stroke of the microswitch 40 button 410 when the connector 80 is ejected and touches the microswitch button. This often affects the on / off function of the microswitch button. Furthermore, since the connector 80 is fixed and tightened to a certain extent after being fixed in the mounting cavity 310 (for example, by using an O-ring on the outside of the connector 80, which fixes the connector 80 in the mounting cavity 310 through the circumferential elasticity and axial friction of the O-ring), it needs a certain impact force to eject from the mounting cavity 310 of the base 30 and trigger the button 410 of the microswitch 40. Therefore, during the assembly process, it is difficult to trigger the button 410 of the microswitch 40 by uniformly and slightly moving the connector 80 axially, thereby determining whether the installation position of the microswitch 40 is appropriate. Thus, it is difficult to fix the position of the microswitch 40 by using the curved surface structure on the connector 80. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art and to provide an integrated tooling and method for fixing and testing microswitches. This device solves the technical problem that the position of the microswitch cannot be fixed by the connector after being installed in the base by converting it into a circumferential rotating tooling.

[0006] To achieve the above objectives, one objective of this invention is to provide an integrated fixture for fixing and testing microswitches, including a base and a calibration seat disposed at the first end of the base. The calibration seat has a calibration surface formed on it for cooperating with the microswitch. When the fixture rotates around its central axis in the mounting cavity of the adapter base, the head end to the tail end of the calibration surface sequentially contacts and continuously presses against the button of the microswitch, thereby achieving positioning and calibration of the installation position of the microswitch by detecting the trigger stroke of the button.

[0007] As a preferred embodiment, the base is a rotating structure, and the calibration surface includes a first convex curved surface, a concave curved surface and a second convex curved surface connected from the head end to the tail end. The button of the micro switch forms a button pressing trajectory in the contact area with the calibration surface from the head end to the tail end. The vertical distance between the button pressing trajectory on the first convex curved surface and the second convex curved surface and the central axis of the base gradually increases from the head end to the tail end.

[0008] As a preferred embodiment, both the first and second convex curved surfaces protrude away from the central axis of the base, while the concave curved surface is recessed towards the central axis of the base. A first straight line segment is formed at the corner where the first convex curved surface and the concave curved surface meet, and a second straight line segment is formed at the corner where the second convex curved surface and the concave curved surface meet. The vertical distance between the first straight line segment and the central axis of the base is less than the vertical distance between the second straight line segment and the central axis of the base.

[0009] As a preferred embodiment, the calibration surface further includes a third convex curved surface, which is connected to the tail end of the second convex curved surface. The central axis of the third convex curved surface coincides with the central axis of the base, and the tail end region of the button pressing trajectory is provided on the third convex curved surface.

[0010] As a preferred embodiment, the first convex surface, the concave surface, the second convex surface, and the third convex surface are all straight surfaces, and the generatrices of the first convex surface, the concave surface, the second convex surface, and the third convex surface are all parallel to the central axis of the base.

[0011] As a preferred embodiment, the tooling is provided with a twisting handle at the center of one end of the calibration seat.

[0012] The second objective of this invention is to provide an integrated method for fixing and detecting microswitches, comprising the following steps:

[0013] Step 1: Assemble the micro switch and connector to form a complete assembly;

[0014] Step 2: Connect the position adjustment holes on both sides of the assembly to the corresponding mounting screw holes on the adapter base using fasteners;

[0015] Step 3: Insert the fixture into the mounting cavity of the adapter base and position it in place. Then rotate the fixture within the mounting cavity so that the button of the micro switch contacts the button pressure trajectory on the calibration surface from the head end to the tail end in sequence. If the position of the micro switch does not meet the test standard, the micro switch is incorrectly installed. Readjust the installation position of the assembly. If the position of the micro switch meets the test standard, tighten and fix the position of the assembly.

[0016] Step 4: Remove the tooling from the adapter base and install the connector into the mounting cavity of the adapter base;

[0017] Step 5: Push the connector outward along the axial direction of the mounting cavity. The button pressing trajectory of the connector's trigger seat from top to bottom will sequentially contact the button of the micro switch to re-test the button's trigger stroke; thereby re-verifying whether the micro switch is properly assembled.

[0018] As a preferred embodiment, in step two, the position adjustment hole is an oblong hole.

[0019] As a preferred embodiment, in step three, the fixture rotates around its central axis during the test. The first end of the button pressing trajectory on the first convex curved surface first contacts the button of the micro switch, and the button is not compressed. Then, the button pressing trajectory contacts the button at the second straight segment, thereby judging whether the button is triggered normally by the trigger sound of the micro switch. Furthermore, the trajectory segment from the button trigger position to the end of the button pressing trajectory on the third convex curved surface is further pressed after the button is triggered by the micro switch to verify the triggering reliability of the micro switch.

[0020] As a preferred embodiment, in step five, the connector's trigger seat is provided with a conical surface and a cylindrical surface that meet from top to bottom. A trigger curve is formed at the junction of the conical surface and the cylindrical surface. The trigger curve is arranged around the central axis of the connector. The connector is pushed outward along the axial direction within the mounting cavity of the adapter base. The top of the button pressing trajectory on the conical surface contacts the button of the micro switch first, and the button is not compressed. Then, the button pressing trajectory contacts the button at the trigger curve. The trigger sound of the micro switch is used to verify whether the micro switch is properly assembled. Furthermore, the trajectory segment from the button trigger position to the end of the button pressing trajectory on the cylindrical surface is used to further verify the button trigger reliability of the micro switch after the micro switch is triggered.

[0021] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0022] Firstly, this invention optimizes the structure and provides an integrated fixture for fixing and testing microswitches. The fixture is equipped with a calibration seat, on which a calibration surface is provided. The calibration surface can maintain contact with the button of the microswitch during the test, thereby pressing the button of the microswitch. As the fixture rotates, the calibration surface can achieve positioning calibration of the microswitch's fixed position.

[0023] Secondly, in this invention, a first convex curved surface, a concave curved surface, a second convex curved surface, and a third convex curved surface are sequentially arranged on the tooling calibration surface. A first calibration position is set on the first convex curved surface. The purpose of setting the concave curved surface is to ensure that the distance between the push button trajectory and the central axis of the base changes abruptly before the trigger point where the concave curved surface and the second convex curved surface meet. This further ensures that the distance between the push button trajectory and the micro switch changes abruptly before the switch is triggered, thus ensuring that the micro switch achieves a more obvious triggering action. In this way, the sound of the triggering action can help determine whether the position of the micro switch is appropriate. The purpose of setting the third convex curved surface is to further compress the button of the micro switch after the switch is triggered, thereby testing the reliability of the micro switch triggering.

[0024] Thirdly, this invention optimizes the positioning and calibration method for the microswitch assembly process. By cooperating with the aforementioned specific structure of the testing fixture, this solution uses the fixture and positioning calibration method to calibrate and position the microswitch. This transforms the axial positioning detection of the connector into detection during rotation via the calibration surface of the fixture. The rotation of the fixture allows for more precise control of the microswitch's button triggering process, thus accurately judging whether the microswitch is properly installed. If the microswitch's triggering process meets all the set positioning detection criteria, the microswitch is considered to be in the correct position. If any positioning detection criterion is not met, it is considered an incorrect position, requiring recalibration by shifting the microswitch. This invention uses a fixture to replace the connector for microswitch position detection, transforming the axial movement of the connector controlling the microswitch's button travel into circumferential control of the microswitch's button travel via the fixture. This achieves a micro-movement effect when controlling the microswitch's button travel by rotating the testing fixture, reducing the installation difficulty of the microswitch, achieving precise positioning, and ensuring reliable triggering after installation.

[0044] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0045] It should be noted that, unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "a," "an," or "the," and similar words used in the specification and claims of this patent application do not express a limitation of quantity, but rather indicate the presence of at least one. Terms such as "comprising" or "including" indicate that the elements or objects preceding "comprising" encompass the elements or objects listed following "comprising" or "including" and their equivalents, but do not exclude other elements or objects having the same function.

[0046] Before introducing the present invention, the control structure of the micro switch to which the present invention applies will be described. The control structure of the micro switch includes a base 3, on which a mounting cavity 31 is formed. A connector 8 is installed in the mounting cavity 31. A micro switch 4 is fixed on a mounting platform 33 of the base 3 located on one side of the mounting cavity 31. The button 41 of the micro switch 4 is arranged facing the mounting cavity 31. Specifically, the micro switch 4 is installed in a fixed cover composed of a base plate 5 and a protective cover 6 to form an assembly 10. The assembly 10 is fastened to the mounting platform 33 of the base by screws. The connector 8 can be pushed outward along the axial direction of the mounting cavity 31, thereby triggering the button 41 of the micro switch 4 by pressing the trigger seat 81 at the top of the connector 8, thereby triggering the micro switch 4 and realizing the on / off state of the micro switch 4.

[0047] In a typical embodiment of the present invention, an integrated fixture for fixing and testing a micro switch is provided, including a base 11 and a calibration seat 12, wherein the calibration seat 12 is disposed at the first end of the base 11, and one end of the calibration seat 12 serves as the top of the fixture 1. Figure 8 The B direction in the figure points towards the top. The shape and size of the base 11 are the same as those of the connector 8, thus ensuring high accuracy when the position detection of the micro switch 4 is performed by replacing the connector 8 with the fixture 1, so as to minimize the error of positioning calibration. That is, except for the twisting handle 14 and the calibration seat 12 that controls the travel of the micro switch 4 button, the other external dimensions of the fixture 1 are the same as the external structural dimensions of the connector body 83.

[0048] In this design, the side of the calibration base 12 facing away from the central axis of the base 11 serves as the calibration surface 120. When the fixture 1 rotates around its central axis within the mounting cavity 31 of the adapter base 3, the head end to the tail end of the calibration surface 120 sequentially contacts and continuously presses against the button 41 of the micro switch 4, thereby performing a full-range test on the trigger stroke of the button 41 of the micro switch 4, and thus achieving positioning calibration of the installation position of the micro switch 4. (In this design, the head end of the calibration base 12 refers to the end that first contacts the button 41 of the micro switch 4 during the test).

[0049] In this embodiment, the calibration surface 120 includes a first convex curved surface 121, a concave curved surface 125, and a second convex curved surface 122. The first convex curved surface 121, the concave curved surface 125, and the second convex curved surface 122 are sequentially connected from the head end to the tail end. The concave curved surface 125 is recessed towards the central axis of the base 11, while the first convex curved surface 121 and the second convex curved surface 122 both protrude outwards away from the central axis of the base 11. With this design, the button on the first convex curved surface 121... The vertical distance between the touch track and the central axis (rotation center) of the base 11 gradually increases from the head end to the tail end. In this design, the edge position (J2) at the head end of the first convex curved surface 121 is the first position to contact the button 41, that is, J2 is the starting point for the calibration surface to contact the button 41. At this point, the calibration surface just contacts the button 41 without pressing against it. As the fixture 1 continues to rotate, the distance between the calibration surface and the micro switch 4 body becomes closer, thus continuously compressing the button 41. A first straight line segment 126 is formed at the corner where the first convex curved surface 121 and the concave curved surface 125 meet, wherein the first straight line segment 126 is parallel to the central axis of the base 11.

[0050] In this embodiment, a second straight segment 127 is provided at the corner where the concave curved surface 125 and the second convex curved surface 122 meet. The second straight segment 127 is also parallel to the central axis of the base 11. In particular, the distance between the button pressing trajectory of the button 41 and the central axis of the base 11 changes abruptly before the trigger point K2 at the second straight segment 127. This ensures that the trigger point K2 can trigger the button 41 with a relatively large and obvious action, thereby making the micro switch 4 emit a more obvious trigger sound, which helps to determine whether the micro switch 4 is installed correctly. The vertical distance between the button contact trajectory of the second convex curved surface 122 and the central axis of the base 11 gradually increases from the beginning to the end. After the button 41 is triggered by the trigger point K2, as the distance between the calibration surface 120 and the micro switch 4 further decreases, the calibration surface 120 can further press the button 41 towards the micro switch 4.

[0051] In this invention, the tail end of the second convex curved surface 122 is connected to the head end of the third convex curved surface 123. A third straight line segment 128 is formed at the corner where the second convex curved surface 122 and the third convex curved surface 123 meet. The third straight line segment 128 is parallel to the central axis of the base 11. The end (L2) of the button pressing trajectory is set on the third convex curved surface 123. Preferably, the central axis of the third convex curved surface 123 is parallel to the central axis of the base 11. This ensures that when the third convex curved surface 123 contacts the button 41, the compression stroke of the button 41 remains basically unchanged, thereby further ensuring that the fixed position of the micro switch 4 achieves high reliability.

[0052] It should be further noted that in this scheme, the first convex surface 121, the concave surface 125, the second convex surface 122, and the third convex surface 123 are connected sequentially, and all are ruled surface structures. The generatrices of the first convex surface 121, the concave surface 125, the second convex surface 122, and the third convex surface 123 are all parallel to the central axis of the base 11. The first straight line segment 126, the second straight line segment 127, and the third straight line segment 128 at their connection points are all parallel to the central axis of the base 11, and the first straight line segment 126, the second straight line segment 127, and the third straight line segment 128 all have a convex ridge structure that protrudes outward away from the central axis of the base 11. The first convex surface 121, the concave surface 125, the second convex surface 122, and the third convex surface 123 are all perpendicular to the cross-section of the base 11. Thus, during the rotation of fixture 1, the contact trajectory between button 41 and the calibration surface is at the same horizontal height (with the central axis of base 11 as a reference). It should be noted that the vertical distance from any point on the contact trajectory of the second convex surface 122 to the central axis of base 11 is D1, and the vertical distance from any point on the contact trajectory of the first convex surface 121 to the central axis of base 11 is D2. D1 is greater than the length value of D2. This ensures that the pressure of the second convex surface 122 on button 41 is greater than the pressure of the first convex surface 121, thereby ensuring that the overall pressure of calibration surface 120 gradually increases throughout the entire rotation process.

[0053] In this design, a torsion handle 41 is provided at the center of one end of the base 11 of the fixture 1 where the calibration seat 12 is located. The purpose of providing the torsion handle 41 is to help manually rotate the fixture 1 around the central axis of the fixture 1 during the test, so as to realize the rotation of the fixture 1 throughout the entire rotation detection process within the mounting cavity 31.

[0054] like Figure 2-9As shown, the trigger seat 81 of connector 8 is provided with a conical surface 811 and a cylindrical surface 812 from top to bottom. A trigger curve 813 is provided at the junction of the conical surface 811 and the cylindrical surface 812. At the thinnest point J1 at the top of the conical surface 811, under normal conditions, contact point J1 just contacts the button 41 of the microswitch 4 but does not press down on the button 41. This contact point J1 corresponds to contact point J2 at the head end of the calibration seat 12 of fixture 1. As the calibration seat 12 of fixture 1 gradually thickens (the button pressing trajectory on the calibration surface 120 gradually moves away from the central axis of the base 11), the upper curved surface structure of the trigger seat 81 gradually thickens (the button pressing trajectory of the conical surface 811 gradually moves away from the central axis of the connector body 83). When the button of the microswitch 4 reaches the trigger point K2 of the trigger microswitch 4 button on the calibration seat 12, the trigger curve 813... K1 is used to trigger the switching function of button 41 of micro switch 4. This K1 corresponds to the trigger point K2 on the calibration seat 12 of fixture 1. In order to ensure the high reliability of triggering button 4 of micro switch 4, the fixture 1 is designed so that after micro switch 4 reaches the trigger state, button 41 will be further compressed for a period of time to reach the final button contact position L2. The contact point L1 on the cylindrical curved surface 812 on the trigger seat 81 of connector 8 corresponds to L2 of fixture 1. In this design, by slightly moving the curved surface of fixture 1 that controls the travel of button 41 of micro switch 4, the curved surface structure on connector 8 that controls the travel of button 41 of micro switch 4 in the axial direction is transformed into a calibration curved surface structure that controls the travel of button 41 of micro switch 4 in the circumferential direction. This method of transforming into a circumferential rotating fixture solves the problem that the position of micro switch 4 cannot be fixed by connector 8 after being installed in the adapter base 3.

[0055] This solution takes into account that after the micro switch 4 is installed in place, the button 41 of the micro switch 4 can just contact the J2 of the calibration surface of the tooling 1, and the button 41 is not compressed by the J2 of the calibration surface. Therefore, the position of the micro switch 4 on the adapter base 3 needs to be adjustable. After the position is adjusted, it is fixed between the base plate 5 and the protective cover 6. The base plate 5 and the protective cover 6 are provided with corresponding waist-shaped holes on both sides. The assembly 10 of the three (micro switch 4, base plate 5 and protective cover 6) formed by the corresponding waist-shaped holes on both sides can achieve a slight positional movement on the mounting platform 33 of the adapter base 6, thereby adjusting the distance between the micro switch 4 and the central axis of the mounting cavity 31, which is equivalent to adjusting the distance between the micro switch 4 and the central axis of the connector 8 or tooling 1 installed in the mounting cavity 31.

[0056] In a typical embodiment of the present invention, an integrated method for fixing and detecting a micro switch is also provided, comprising the following steps: Step 1, fixing the micro switch 1 between the base plate 5 and the protective cover 6 to form an assembly 10; Figure 12 As shown, points A and B on the protective cover 6 and the micro switch 4 are through holes. After assembling the assembly 10, screws or bolts are screwed into holes A and B to fix the three parts into one.

[0057] Step 2: The position adjustment holes 101 on both sides of the assembly 10 obtained in Step 1 are screwed into the corresponding mounting screw holes 32 of the adapter base 3 using fasteners (not shown). The position adjustment holes 101 are designed as oblong holes. This design takes into account that the assembly 10 as a whole needs to be closer to or further away from the mounting cavity 31 of the adapter base 3, thereby adjusting the distance between the button 41 of the micro switch 4 and the central axis of the connector 8 or tooling 1 in the mounting cavity 31. Specifically, the assembly 10 is slightly screwed into the mounting screw holes 32 of the mounting platform 33 using screws. The oblong hole design of the position adjustment holes 101 ensures that the assembly 10 as a whole can be adjusted relative to the mounting cavity 31 in the approach or distance direction.

[0058] Step 3: Insert fixture 1 into the mounting cavity 31 of the adapter base 3 and position it in place. Then rotate fixture 1 around its central axis within the mounting cavity 31 so that the button 41 of the micro switch 4 of the assembly 10 contacts the button pressure trajectory of the calibration surface 120 from the head end to the tail end in sequence. Adjust fixture 1 to the appropriate installation position. If the position of the micro switch 4 does not meet the test requirements, it is an incorrect position. Readjust the installation position of the assembly 10. If the position of the micro switch 4 meets the test requirements, fix the position of the assembly 10.

[0059] Specifically, after assembling the fixture 1 and the O-ring, for example, installing the O-ring in the groove 13 to maintain consistency with the fixed state of the connector 8, insert the second end of the fixture 1 into the mounting cavity 31 of the adapter base 3, taking care to avoid obstructing the button 41 of the micro switch 4. After the fixture 1 is in place, gently move the assembly 10 so that the button 41 of the micro switch 4 is slightly against the edge of the fixture 1, maintaining contact without gaps and without compression. At this point, tighten the fasteners (screws) on both sides of the assembly 10. Looking at the top of the fixture 1 from a top angle, rotate the fixture 1 clockwise from point J to point K. The button 41 of the micro switch 4 is gradually compressed. When it reaches the trigger point K, a crisp trigger sound can be heard. This trigger sound is the trigger sound of the micro switch 4. Figure 14 As shown, continue rotating fixture 1 from point K to point L. It can be observed that button 41 will continue to be further compressed. This indicates that the fixed position of micro switch 4 is appropriate. If any of the above judgment criteria cannot be met, the installation position of micro switch 4 is incorrect. In this case, the fixed position of assembly 10 needs to be adjusted, and the test steps in step three should be continued until the correct position is reached.

[0060] In this design, after button 41 passes through the first straight segment 126, the distance between its button pressing trajectory and the central axis of base 11 increases at a slower rate. The purpose of this design is to ensure that when button 41 comes into contact at the second straight segment 127 between the concave curved surface 125 and the second convex curved surface 122, the calibration surface 120 undergoes a significant positional change, triggering button 41 and causing the micro switch 4 to be clearly triggered. Because the distance between the button contact trajectory and base 11 before and after the second straight segment 127 changes abruptly, a crisp sound will be heard when button 41 is triggered, which helps to determine whether the micro switch 4 is installed correctly.

[0061] In this design, the concave surface 125 is recessed towards the central axis of the base 11. From the side away from the concave surface 125 to the side gradually approaching the concave surface 125, the vertical distance between the trigger point trajectory on the first convex surface 121 and the central axis of the base 11 gradually increases. From the side closer to the concave surface 125 to the side gradually away from the concave surface 125, the vertical distance between the trigger point trajectory on the second convex surface 122 and the central axis of the base 11 gradually increases.

[0062] Step 4: Remove fixture 1 from adapter base 3, install O-ring in groove 82 of connector 8, and then install connector 8 in mounting cavity 31 of adapter base 3. The function of O-ring here is to fix connector 8.

[0063] Step 5: Push the connector 8 outward along the axial direction of the mounting cavity 31 of the adapter base 3. The button pressing trajectory of the trigger seat 81 of the connector 8 from the top to the bottom will sequentially press and contact the button 41 of the micro switch 4 to re-detect the trigger stroke of the button 41 of the micro switch 4; thereby determining whether the micro switch 4 is properly assembled.

Claims

1. An integrated fixture for fixing and detecting micro switches, characterized in that: It includes a base and a calibration seat disposed at the first end of the base. The calibration seat has a calibration surface formed on it for cooperating with a micro switch. When the tooling rotates around its central axis in the mounting cavity of the adapter base, the head end to the tail end of the calibration surface sequentially contacts and continuously presses against the button of the micro switch, thereby realizing the positioning and calibration of the installation position of the micro switch by detecting the trigger stroke of the button. The base is a rotating structure. The calibration surface includes a first convex curved surface, a concave curved surface and a second convex curved surface connected from the head end to the tail end. The button of the micro switch forms a button pressing trajectory in the contact area with the calibration surface from the head end to the tail end. The vertical distance between the button pressing trajectory on the first convex curved surface and the second convex curved surface and the central axis of the base gradually increases from the head end to the tail end. Both the first and second convex curved surfaces protrude away from the central axis of the base, while the concave curved surface is recessed towards the central axis of the base. A first straight line segment is formed at the corner where the first convex curved surface and the concave curved surface meet, and a second straight line segment is formed at the corner where the second convex curved surface and the concave curved surface meet. The vertical distance of the first straight line segment from the central axis of the base is less than the vertical distance of the second straight line segment from the central axis of the base.
