Description

Technical Field

[0001] This application relates to the field of RF connector assembly, and particularly to an anti-fooling fixture for welding an SMA RF connector automatic welding machine. Background Art

[0002] SMA RF connectors are applicable to applications in the microwave field with a frequency range up to 26.5 GHz, such as telecommunications, networks, wireless communications, and testing and measurement instruments, and have the characteristics of wide bandwidth, excellent performance, high reliability, and long life.

[0003] Currently, when assembling RF connectors, workers need to manually place the RF connector body at the automatic welding equipment, and then the automatic welding equipment welds the RF connector body. To ensure the accuracy of welding, the operation requirements for workers are relatively high. The RF connector body needs to be accurately placed so that the subsequent automatic welding equipment can perform precise welding. As a result, there are problems such as a low anti-fooling coefficient during welding of the RF connector body and easy occurrence of welding deviation. Summary of the Utility Model

[0004] In order to improve the anti-fooling coefficient during welding of the RF connector body, this application provides an anti-fooling fixture for welding an SMA RF connector automatic welding machine.

[0005] The anti-fooling fixture for welding an SMA RF connector automatic welding machine provided by this application adopts the following technical solutions:

[0006] An anti-fooling fixture for welding an SMA RF connector automatic welding machine includes a base, a positioning seat, a limiting clamping seat, and a pressing mechanism. The base is set at a set position of the automatic welding equipment. The positioning seat is arranged on the base and is used for inserting into a hole on one side of the RF connector body. The limiting clamping seat is arranged on the base, and a limiting groove for the RF connector body to be clamped into is formed on the limiting clamping seat. The pressing mechanism is arranged on the base and is used for pressing against the side of the RF connector body away from the positioning seat.

[0007] By adopting the above technical solutions, workers install the base at the set position of the automatic welding equipment, then move the RF connector body to be welded, so that the RF connector body is clamped into the limiting groove, and at the same time, the positioning seat is inserted into the hole on one side of the RF connector body. Then, the pressing mechanism presses against the side of the RF connector body away from the positioning seat, and the RF connector body can be positioned on the base, and then the RF connector body is assembled according to the set position, which is convenient for the subsequent automatic welding equipment to perform accurate welding and improves the anti-fooling coefficient during welding of the RF connector body.

[0008] Optionally, the pressing mechanism includes a pressing seat, a spring, and a control member. The pressing seat is slidably disposed on the base in the direction towards the positioning seat. The spring is disposed on the base and connected to the pressing seat. The spring always has a tendency to drive the pressing seat to slide towards the positioning seat. The control member is disposed on the base and is used to drive the pressing seat to slide.

[0009] By adopting the above technical solution, the staff first drives the pressing seat to slide away from the positioning seat through the control member. After assembling the RF connector body between the positioning seat and the pressing seat, the spring can drive the pressing seat to slide towards the positioning seat, and the pressing seat can continuously press against the side of the RF connector body away from the positioning seat, clamping the RF connector body conveniently and quickly.

[0010] Optionally, the control member includes a control rod and a handle. The control rod is slidably disposed on the base along the sliding direction of the pressing seat. The control rod is connected to the pressing seat, and the handle is disposed on the control rod.

[0011] By adopting the above technical solution, when the staff pulls the handle, the handle can drive the pressing seat to slide along the direction towards the positioning seat through the control rod, conveniently adjusting the position of the pressing seat.

[0012] Optionally, a guide rod is disposed on the base. The guide rod slidably penetrates through the pressing seat, and the spring is wound around the outer periphery of the guide rod.

[0013] By adopting the above technical solution, the guide rod guides the sliding of the pressing seat, improving the stability of the pressing seat during the sliding process. And the guide rod can also support the spring, improving the stability of the spring during the telescopic process.

[0014] Optionally, a clamping seat for the RF connector body to be snapped into is disposed on the base.

[0015] By adopting the above technical solution, the RF connector body is snapped into the clamping seat, and the clamping seat limits the RF connector body, further improving the accuracy of assembling the RF connector body on the base.

[0016] Optionally, a buffer block is disposed on the pressing seat. When the pressing seat presses against the RF connector body, the buffer block abuts against the clamping seat.

[0017] By adopting the above technical solution, when the abutting seat slides towards the positioning seat and presses against the RF connector body, the buffer block can abut against the clamping seat, reducing the impact of the abutting seat on the RF connector body.

[0018] Optionally, a stop block is provided on the base. When the pressing seat presses against the RF connector body, the end of the handle close to the positioning seat abuts against the stop block.

[0019] By adopting the above technical solution, when the pressing seat presses against the RF connector body, the pressing seat drives the handle to move, and the end of the handle close to the positioning seat abuts against the stop block, restricting the pressing seat from continuing to move in the direction close to the positioning seat, thereby limiting the movement of the pressing seat in the direction close to the positioning seat.

[0020] Optionally, the stop block is slidably arranged on the base. A slotted hole is provided on the stop block, and an adjusting bolt is threadedly arranged on the base. The adjusting bolt passes through the slotted hole and abuts against the stop block.

[0021] By adopting the above technical solution, the staff unscrews the adjusting bolt from the base to release the pressing of the adjusting bolt on the stop block, and then the position of the stop block can be adjusted to make the stop block yield from the moving path of the handle. The handle can then move a greater distance in the direction close to the positioning seat, and further the pressing seat can move a greater distance in the direction close to the positioning seat, so that the pressing seat can press a smaller-sized RF connector body against the positioning seat.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Position the RF connector body on the base, and then assemble the RF connector body at the set position, which is convenient for subsequent automatic welding equipment to perform accurate welding and improves the anti-fooling coefficient when welding the RF connector body.

[0024] 2. The spring can drive the pressing seat to slide in the direction close to the positioning seat, and the pressing seat can continuously press against the side of the RF connector body far from the positioning seat, quickly and conveniently clamping the RF connector body.

[0025] 3. Adjust the position of the stop block to make the stop block yield from the moving path of the handle. The handle can then move a greater distance in the direction close to the positioning seat, and further the pressing seat can move a greater distance in the direction close to the positioning seat, so that the pressing seat can press a smaller-sized RF connector body against the positioning seat.

Specific embodiments

[0029] The following will Figure 1-2 further elaborate on this application in detail.

[0030] The embodiment of this application discloses a foolproof fixture for welding an SMA radio frequency connector automatic welding machine.

[0031] Referring to Figure 1 , the foolproof fixture for welding an SMA radio frequency connector automatic welding machine includes a base 1, a positioning seat 2, a limit clamping seat 3 and a pressing mechanism 4.

[0032] Referring to Figure 1 , the base 1 is fixedly installed at a set position of the automatic welding equipment, the positioning seat 2 is installed on one side of the base 1, and a plurality of protrusions protrude at intervals along the width direction of the base 1 on the side of the positioning seat 2 facing the other side of the base 1. The protrusions are used for inserting into the holes on one side of the radio frequency connector body.

[0033] The operator moves the radio frequency connector body to be welded, so that the protrusions of the positioning seat 2 are inserted into the holes on one side of the radio frequency connector body, and the protrusions of the positioning seat 2 can position one side of the radio frequency connector body.

[0034] Referring to Figure 1 , the limit clamping seat 3 is installed on the base 1, and a plurality of limit grooves 31 are arranged at intervals along the width direction of the base 1 on the limit clamping seat 3. The plurality of limit grooves 31 respectively correspond to the plurality of protrusions on the positioning seat 2, and the limit grooves 31 are used for the radio frequency connector body to be clamped into.

[0035] The operator moves the radio frequency connector body, so that the radio frequency connector body is clamped into the limit groove 31. The side wall of the limit groove 31 can limit the radio frequency connector body, restrict the movement of the radio frequency connector body in the width direction of the base 1, and improve the stability of the radio frequency connector body.

[0036] Referring to Figure 1, the tightening mechanism 4 is installed on the base 1. The tightening mechanism 4 is used to tighten against the side of the RF connector body away from the positioning seat 2. The tightening mechanism 4 includes a tightening seat 41, a spring 42 and a control member 43. The tightening seat 41 is slidably installed on the side of the base 1 away from the positioning seat 2 in the direction towards the positioning seat 2. One end of the spring 42 is installed on the positioning seat 2, and the other end of the spring 42 is installed on the side of the tightening seat 41 away from the positioning seat 2. The spring 42 always has a tendency to drive the tightening seat 41 to move towards the positioning seat 2. A guide rod 5 is installed on the base 1 along the sliding direction of the tightening seat 41. The guide rod 5 slidably penetrates through the tightening seat 41, and the spring 42 is wound around the outer periphery of the guide rod 5.

[0037] The guide rod 5 guides the movement of the tightening seat 41, so that the tightening seat 41 can only slide along the direction of approaching or departing from the positioning seat 2, effectively improving the stability of the tightening seat 41 during the sliding process. Moreover, the guide rod 5 can also provide support for the spring 42, improving the stability of the spring 42 during the telescopic process.

[0038] Refer to Figure 1 , the control member 43 is installed on the base 1. The control member 43 is used to drive the tightening seat 41 to slide on the base 1. The control member 43 includes a control rod 431 and a handle 432. The control rod 431 slidably penetrates through the base 1 along the sliding direction of the tightening seat 41. The control rod 431 is connected to the tightening seat 41, and the handle 432 is installed at one end of the control rod 431 away from the tightening seat 41.

[0039] The staff first pulls the handle 432 in the direction away from the positioning seat 2. The handle 432 drives the control rod 431 to move, and the control rod 431 can drive the tightening seat 41 to slide along the direction away from the positioning seat 2. Then, the RF connector body is snapped into the limit groove 31, and the protrusion of the positioning seat 2 is snapped into the hole on one side of the RF connector body. Then, the handle 432 is released, and the spring 42 can drive the tightening seat 41 to slide towards the positioning seat 2. The tightening seat 41 tightens against the side of the RF connector body away from the positioning seat 2, so as to position the RF connector body, and then complete the assembly of the RF connector body at the set position on the base 1, facilitating the subsequent automatic welding equipment to perform accurate welding according to the set stroke, and effectively improving the anti-fooling coefficient when welding the RF connector body.

[0040] Refer to Figure 1 , Figure 2 , a stopper 8 is slidably installed on the side of the base 1 away from the positioning seat 2 in the vertical direction. A slot 81 is vertically opened on the stopper 8. An adjusting bolt 9 is threadedly installed on the base 1. The adjusting bolt 9 passes through the slot 81 to tighten the stopper 8 against the base 1. The stopper 8 is used to abut against one end of the handle 432 close to the positioning seat 2 when the tightening seat 41 tightens against the RF connector body.

[0041] The staff adjusts the stopper 8 to between the handle 432 and the base 1, then turns the adjusting bolt 9 to lock the stopper 8. Subsequently, when the abutting seat 41 moves towards the positioning seat 2 under the action of the spring 42 and abuts against the RF connector body, the abutting seat 41 drives the handle 432 to move towards the base 1. One end of the handle 432 close to the positioning seat 2 can abut against the stopper 8, restricting the further movement of the abutting seat 41 towards the positioning seat 2. At this time, the abutting seat 41 just abuts against the RF connector body, thereby limiting the movement of the abutting seat 41 towards the positioning seat 2 and controlling the force of the abutting seat 41 against the RF connector body, reducing the possibility of damage to the RF connector caused by excessive force of the abutting seat 41 against the RF connector body; when it is necessary to abut a RF connector body with a smaller size specification against the positioning seat 2, the staff unscrews the adjusting bolt 9 from the base 1 to release the abutment of the adjusting bolt 9 on the stopper 8 on the base 1. The spring 42 moves the stopper 8 downward to move out of the area between the stopper 8 and the base 1, so that the stopper 8 can give way from the moving path of the handle 432. The handle 432 can move a greater distance towards the positioning seat 2, so that the abutting seat 41 can move a greater distance towards the positioning seat 2, enabling the abutting seat 41 to abut the smaller specification RF connector body against the positioning seat 2 and improving the applicability to RF connectors of different specifications.

[0042] Refer to Figure 1 , a plurality of clamping seats 6 are installed on the base 1 at intervals along the width direction of the base 1. The plurality of clamping seats 6 respectively correspond to the plurality of limiting grooves 31 one by one. The upper part of the clamping seat 6 is open and open towards the side of the abutting seat 41. The clamping seat 6 is used for the RF connector body to be clamped into.

[0043] When the staff assembles the RF connector body onto the base 1, the RF connector body is clamped into the clamping seat 6, and the clamping seat 6 can limit the RF connector body, further improving the stability and position accuracy of the RF connector body assembled on the base 1.

[0044] Refer to Figure 1 , a plurality of buffer blocks 7 are installed on the side of the abutting seat 41 towards the positioning seat 2 at intervals along the width direction of the base 1. The plurality of buffer blocks 7 respectively correspond to the plurality of clamping seats 6 one by one. The buffer block 7 is used for abutting against the clamping seat 6 from the opening of the clamping seat 6 when the abutting seat 41 abuts against the RF connector body. In this embodiment, the buffer block 7 is a rubber block.

[0045] When the abutting seat is tightened against the RF connector body, the tightening seat 41 drives the buffer block 7 to be inserted into the clamping seat 6. The side wall of the clamping seat 6 guides the movement of the buffer block 7, thereby guiding the sliding of the tightening seat 41. At the same time, when the buffer block 7 abuts against the clamping seat 6, it can provide buffering for the tightening seat 41 and reduce the impact of the abutting seat on the RF connector body.

[0046] The implementation principle of the anti-fooling fixture for automatic welding of the SMA RF connector in the embodiment of the present application is as follows: The operator pulls the handle 432 to make the tightening seat 41 away from the positioning seat 2, and then respectively inserts a plurality of RF connector bodies to be welded into a plurality of limit clamping seats 3, and makes a plurality of protrusions on the positioning seat 2 respectively inserted into the holes on one side of a plurality of RF connector bodies. At the same time, a plurality of RF connector bodies are respectively inserted into a plurality of clamping seats 6, and then the handle 432 is released. The tightening seat 41 slides towards the positioning seat 2 under the action of the spring 42, and the tightening seat 41 can be tightened against the side of the RF connector away from the positioning seat 2, positioning a plurality of RF connector bodies on the base 1, and then assembling a plurality of RF connector bodies on the automatic welding equipment according to the set positions, which is convenient for the subsequent automatic welding equipment to accurately weld the RF connector according to the set stroke, reduces the difficulty for the operator to accurately position the RF connector body at the automatic welding equipment, effectively improves the anti-fooling coefficient when welding the RF connector body, and reduces the possibility of deviation when welding the RF connector body.

[0047] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
