Description

Technical Field

[0001] This utility model relates to the field of isolator assembly technology, and more specifically, to a fixture for isolator assembly. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] In industrial automation control systems, isolators are instruments used to achieve signal isolation, conversion and transmission. Their housings are usually provided with mounting ports that are symmetrically distributed vertically around a horizontal axis, for mounting a large number of wiring terminals.

[0004] Currently, the assembly of terminals for this type of isolator largely relies on manual operation, requiring operators to hold the housing and press the terminals into the mounting openings sequentially. However, this traditional method has significant drawbacks: First, after assembling the terminals on the upper part of the housing, the housing needs to be rotated 180° to continue assembling the terminals on the lower part. During this process, it is difficult for operators to maintain a stable grip on the housing, leading to low assembly efficiency and potentially causing inconsistencies in the assembly of the upper and lower terminals due to changes in the positioning reference. Second, it is difficult to control the force applied during hand operation, easily causing scratches on the housing surface or even damage to the internal structure due to slippage or squeezing. This is especially true when the housing has a snap-fit ​​structure on the back; improper grip can easily damage this snap-fit ​​structure, severely impacting product yield. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide a fixture for assembling isolators, so as to at least overcome the above-mentioned technical problems existing when manually assembling the housing and terminals.

[0006] The objective of this utility model is achieved through the following technical solution: This utility model provides a fixture for assembling an isolator, the isolator including a housing, the housing having mounting openings symmetrically distributed about a horizontal axis; The clamp includes: Base; A turntable is rotatably mounted on the base; A clamping mechanism is provided on the turntable and is used to clamp and fix the housing; When the housing is clamped and fixed, the rotation axis of the turntable coincides with the horizontal axis.

[0007] Optionally, the clamping mechanism includes two clamping members disposed opposite each other, and a drive structure for driving the two clamping members to move relative to each other.

[0008] Optionally, the drive structure includes a lead screw rotatably mounted on the turntable; The lead screw has two external thread sections with opposite thread directions; the two clamping members are respectively threadedly connected to the two external thread sections.

[0009] Optionally, the drive structure further includes a guide rod that is parallel to the lead screw and fixedly mounted on the turntable; Both clamping members are slidably engaged with the guide rod.

[0010] Optionally, a hand crank is connected to one end of the lead screw.

[0011] Optionally, protective pads are provided on the clamping surfaces of both clamping members.

[0012] Optionally, the two clamping members are located on the front side of the turntable, and the driving structure is located on the back side of the turntable; The turntable has clearance openings that extend through the front and back of the turntable and allow the clamping member to pass through.

[0013] Optionally, the turntable is provided with a snap-fit ​​guide rail for engaging with a snap-fit ​​structure on the housing.

[0014] Optionally, the engaging guide rail is detachably mounted on the turntable.

[0015] Optionally, a drive motor is fixedly mounted on the base; The output end of the drive motor is connected to the turntable for driving the turntable to rotate.

[0016] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects: The isolator assembly fixture provided by this utility model, by setting a clamping mechanism on a rotatable turntable for clamping and fixing the housing, allows the operator to rotate the symmetrically distributed mounting openings on the housing sequentially to the upward position for easy installation of wiring terminals without disassembling the housing after clamping it. This effectively improves the assembly accuracy and consistency of the wiring terminals assembled in the upper and lower mounting openings. At the same time, this integrated clamping and flipping process not only frees the operator from the complicated and cumbersome manual support and flipping work, but also replaces manual operation with mechanical positioning, avoiding scratches on the housing surface or damage to the buckle structure caused by unstable hand or improper force, thus reducing the assembly defect rate and loss risk of the product.

[0022] Please refer to Figures 1 to 6 As shown, an embodiment of this utility model provides a fixture for assembling an isolator.

[0023] According to embodiments of this utility model, the isolator is specifically an instrument used in industrial control systems to achieve signal isolation, conversion, and transmission. Specifically, such as... Figure 1 As shown, the isolator includes a housing 101. The housing 101 has mounting openings symmetrically distributed about a horizontal axis s, each for mounting a terminal block 102. Furthermore, the housing 101 also has a snap-fit ​​structure 103 for engaging with a standard DIN rail.

[0024] Preferably, all mounting ports on the housing 101 are located at the front end of the housing 101, and all mounting ports are divided into two groups, symmetrically distributed on the upper and lower parts of the housing 101 with the horizontal axis s as the axis of symmetry. The snap-fit ​​structure 103 is located at the rear end of the housing 101.

[0025] To assist operators in assembling the wiring terminals 102 of this type of isolator, according to an embodiment of the present invention, such as... Figure 2 and Figure 3 As shown, the fixture includes a base 10, a turntable 20, and a clamping mechanism 30.

[0026] The turntable 20 is rotatably mounted on the base 10. Preferably, a drive motor 40 is fixedly mounted on the base 10, and the output end of the drive motor 40 is connected to the turntable 20 for driving the turntable 20 to rotate.

[0027] The clamping mechanism 30 is disposed on the turntable 20 and is used to clamp and fix the housing 101 so as to temporarily fix the housing 101 on the turntable 20.

[0028] When the housing 101 is clamped and fixed, the rotation axis of the turntable 20 coincides with the horizontal axis s. That is, after the housing 101 is clamped and fixed, if the turntable 20 rotates, the mounting openings located at the upper and lower parts of the front end of the housing 101 will rotate around the rotation axis of the turntable 20.

[0029] Based on the above settings, the assembly of the terminal block 102 on the isolator can be completed using the following procedure.

[0030] Specifically, refer to Figure 4 As shown, the isolator housing 101 is first clamped and fixed onto the turntable 20 by the clamping mechanism 30, and the horizontal axis S is aligned with the rotation axis of the turntable 20. At this time, the mounting port at the upper front end of the housing 101 faces upward. Based on this, the operator can install the wiring terminal 102 in the mounting port at the upper part of the housing 101 without holding the housing 101 in hand.

[0031] After the wiring terminals 102 on the upper part of the housing 101 are assembled, the drive motor 40 drives the turntable 20 to rotate 180°, so that the mounting opening on the upper part of the housing 101 with the wiring terminals 102 installed faces downward, and the mounting opening on the lower part without the wiring terminals 102 installed faces upward. Afterward, the operator can install the wiring terminals 102 in the mounting opening on the lower part of the housing 101 without holding the housing 101 in their hand.

[0032] The isolator assembly fixture provided in this embodiment of the utility model, by setting a clamping mechanism 30 on a rotatable turntable 20 for clamping and fixing the housing 101, allows the operator to rotate the symmetrically distributed mounting openings on the housing 101 sequentially to the upward position for easy installation of the wiring terminals 102 after clamping the housing 101 without disassembling the housing 101. This effectively improves the assembly accuracy and consistency of the wiring terminals 102 assembled in the upper and lower mounting openings. At the same time, this integrated clamping and flipping process not only frees the operator from the complicated and cumbersome manual support and flipping labor, but also replaces manual operation with mechanical positioning, avoiding scratches on the surface of the housing 101 or damage to the buckle structure 103 caused by unstable hand grip or improper force, thus reducing the assembly defect rate and loss risk of the product.

[0033] In some possible embodiments, refer to Figure 2 and Figure 3 As shown, the clamping mechanism 30 includes two clamping members 31 arranged opposite to each other, and a drive structure 32 for driving the two clamping members 31 to move relative to each other. The two clamping members 31 are symmetrically distributed about the rotation axis of the turntable 20.

[0034] Based on the above configuration, when it is necessary to clamp and fix the housing 101, simply place the housing 101 between the two clamping members 31, and use the driving structure 32 to drive the two clamping members 31 closer to each other. The housing 101 can then be clamped and fixed from opposite sides by the two clamping members 31. Conversely, the housing 101 can be released by simply using the driving structure 32 to drive the two clamping members 31 further apart.

[0035] This type of clamping mechanism 30 not only has high clamping reliability and is suitable for clamping and fixing housings 101 of various sizes, but also is simple and convenient to operate, which is conducive to the quick assembly and disassembly of housings 101.

[0036] Furthermore, referring to Figure 5 As shown, protective pads 33 are provided on the clamping surfaces of both clamping members 31. The clamping surface of the clamping member 31 refers to the side of the clamping member 31 that contacts the housing 101 when clamping and fixing the housing 101.

[0037] The protective pad 33 serves to protect the housing 101 and reduce the risk of damage to the housing 101 when the clamping member 31 clamps the housing 101. Preferably, the protective pad 33 can be a rubber pad.

[0038] Additionally, refer to Figure 2 and Figure 3 As shown, two clamping members 31 are located on the front of the turntable 20, and the drive structure 32 is located on the back of the turntable 20. The turntable 20 is provided with clearance openings 21 that penetrate through the front and back of the turntable 20 and allow the clamping members 31 to pass through. Each clamping member 31 passes through the corresponding clearance opening 21 and is then connected to the drive structure 32 for transmission.

[0039] By arranging the clamping component 31 and the driving structure 32 on the front and back sides of the turntable 20 respectively, the overall fixture structure is optimized and the aesthetics of the entire fixture are improved.

[0040] In some possible embodiments, refer to Figure 3 and Figure 5 As shown, the drive structure 32 may include a lead screw 321 and a guide rod 322. The lead screw 321 is rotatably mounted on the turntable 20 via a bearing housing 323, specifically on the back side of the turntable 20. The lead screw 321 has two external thread sections with opposite thread directions. The guide rod 322 is parallel to the lead screw 321 and is fixedly mounted on the turntable 20, specifically on the back side of the turntable 20.

[0041] After passing through the corresponding clearance openings 21, the two clamping members 31 are threadedly connected to the two external thread sections respectively. In addition, both clamping members 31 are in sliding engagement with the guide rod 322.

[0042] With this configuration, when the control screw 321 rotates, based on the principle of threaded transmission, the two clamping members 31 will move in opposite directions along the axial direction of the screw 321, thereby causing the two clamping members 31 to move closer or further apart. This type of drive structure 32 enables stepless adjustment of the position of the clamping members 31. Simultaneously, based on the self-locking property of the screw 321 transmission, the position of the clamping members 31 can be locked, thereby improving the clamping and fixing effect.

[0043] To facilitate operator control of the lead screw 321 rotation, refer to... Figure 5 As shown, a hand crank 324 is connected to one end of the lead screw 321.

[0044] In some possible embodiments, in conjunction with the foregoing, based on the snap-fit ​​structure 103 provided on the housing 101, referring to... Figure 2 and Figure 6 As shown, the turntable 20 is provided with a locking guide rail 50 for engaging with the snap-fit ​​structure 103 on the housing 101.

[0045] By using the engaging guide rail 50, before clamping and fixing the housing 101, the snap-fit ​​structure 103 of the housing 101 can be engaged with the engaging guide rail 50 to achieve temporary positioning of the housing 101. Then, the two clamping members 31 of the clamping mechanism 30 are brought closer together to clamp and fix the housing 101. This design not only ensures that the horizontal axis S is smoothly aligned with the rotation axis of the turntable 20 after the housing 101 is clamped and fixed, but also provides limiting and support for the housing 101 from the rear, further improving the stability of the housing 101 after it is clamped and fixed.

[0046] In a preferred embodiment, the engaging guide rail 50 is a standard DIN rail. Furthermore, the engaging guide rail 50 can be detachably mounted on the turntable 20 using fasteners (e.g., bolts) to facilitate replacement of the engaging guide rail 50.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
