Description

TECHNICAL FIELD

[0001] The utility model relates to optical device processing technical field, provide a rotatable positionable welding device specifically. BACKGROUND

[0002] When the optical device is connected with the optical fiber, welding fixation is a common processing mode. The optical fiber end is connected with the optical device, an insertion end with a built-in optical element is arranged at the optical fiber end, and a jack is arranged on the shell of the optical device. After the insertion end is inserted into the jack, the insertion end is welded and connected with the shell. In order to ensure the stable connection of the insertion end and the shell, spot welding is performed in the circumferential direction of the insertion end.

[0003] However, because the size of the optical device is very small, when electric welding is performed in the circumferential direction of the insertion end of the optical fiber, the welding gun will contact the optical device. When the welding gun contacts the optical device, the optical device is easily rotated under the action force, which causes the welding spot spacing to be easily uneven, so that the connection points of the insertion end of the optical fiber and the shell of the optical device are unevenly distributed, resulting in uneven force on the insertion end of the optical fiber. Uneven force on the insertion end of the optical fiber will cause unstable connection of the insertion end of the optical fiber and the shell of the optical device, and the insertion end of the optical fiber is easily detached. SUMMARY

[0004] The utility model provides a rotatable positionable welding device, which is used to solve the problem that when electric welding is performed in the circumferential direction of the insertion end of the optical fiber, the welding gun contacts the optical device, causing the optical device to rotate under the action force, which causes the welding spot spacing to be easily uneven, resulting in unstable connection of the insertion end of the optical fiber and the shell of the optical device, and the insertion end of the optical fiber is easily detached.

[0005] The technical scheme of the utility model is as follows:

[0006] A rotatable positionable welding device, comprising a base, a clamping assembly and a positioning structure, the clamping assembly is rotatably connected with the base, the clamping assembly positioning structure is arranged between the clamping assembly and the base, the positioning structure is used for positioning the rotation angle of the clamping assembly, the clamping assembly is used for clamping and fixing the optical device, and the rotation center of the clamping assembly is coaxial with the insertion end of the optical fiber.

[0007] In the scheme, the clamping assembly is positioned by the positioning structure when rotating, so that the clamping assembly can stop at a specified position. When the clamping assembly can stop at a specified position for welding, the welding position is fixed. Therefore, the positioning structure is reasonably arranged, so that the clamping assembly is positioned after rotating a fixed angle each time, so that the welding gun can be welded at equal angles in the circumferential direction of the insertion end of the optical fiber. When welding, the positioning structure increases the rotating resistance of the clamping assembly, avoids the welding gun contacting the optical device to cause the clamping assembly to rotate, makes the welding position more accurate, and the welding points on the insertion end of the optical fiber are more evenly distributed, thereby ensuring that the insertion end of the optical fiber is evenly stressed, and the connection between the insertion end of the optical fiber and the shell of the optical device is more stable.

[0008] Preferably, the positioning structure comprises an elastic body and a positioning hole, and the elastic body and the positioning hole are arranged on the clamping assembly and the base respectively, and the positioning hole is located on the movement path of the elastic body.

[0009] In the scheme, the elastic body and the positioning hole are matched, and the elastic body is clamped into the positioning hole under the action of its own elastic force when the elastic body moves to the position of the positioning hole, thereby positioning the clamping assembly. The elastic body can be clamped into the positioning hole by its own elastic force, and the rotating resistance of the clamping assembly will suddenly increase after the elastic body is clamped into the positioning hole, so that the operator can directly know that the clamping assembly has rotated a specified angle through touch, and welding can be performed.

[0010] Preferably, the welding device comprises a plurality of positioning holes, and the positioning holes are distributed at equal angles relative to the center of rotation of the clamping assembly.

[0011] In the scheme, the plurality of positioning holes can make the clamping assembly be positioned with the elastic body multiple times during rotation, so as to position the clamping assembly multiple times, thereby enabling the welding gun to weld multiple times. The equal-angle distribution of the positioning holes relative to the center of rotation of the clamping assembly can ensure that the welding points formed by welding are equally distributed on the insertion end of the optical fiber.

[0012] Preferably, guide grooves are arranged between the positioning holes, and the two ends of the guide grooves coincide with the first positioning hole and the last positioning hole respectively along the rotating direction of the clamping assembly.

[0013] In the scheme, the guide grooves are arranged between the positioning holes to guide the elastic member to move along the guide grooves. The two ends of the guide grooves coincide with the first positioning hole and the last positioning hole respectively, so as to prevent the elastic member from moving from the last positioning hole to the first positioning hole. This arrangement can remind the operator that welding is completed, and avoid the clamping assembly rotating again to cause the welding gun to repeatedly weld a point on the insertion end of the optical fiber.

[0014] As an alternative, the bottom surface of the clamping assembly is provided with elastic bodies or positioning holes, and the top surface of the base is provided with positioning holes or elastic bodies.

[0015] In this scheme, the positioning structure is located between the bottom of the clamping assembly and the top surface of the base, and has the advantages of simple structure.

[0016] As another alternative, the side surface of the clamping assembly is provided with elastic bodies or positioning holes, the top surface of the base is provided with a positioning block, the positioning block is located on one side of the clamping assembly, and the positioning block is provided with positioning holes or elastic bodies corresponding to the clamping assembly.

[0017] In this scheme, the positioning block is arranged on one side of the clamping assembly, and the positioning structure is arranged between the side surface of the clamping assembly and the positioning block, so that the positioning assembly only gives the clamping assembly a radial reaction force and does not cause the clamping assembly to tilt.

[0018] Preferably, one side of the positioning block close to the clamping assembly is an arc surface, and the axis of the arc surface coincides with the center of rotation of the clamping assembly.

[0019] In this scheme, the positioning block is provided with an arc surface, so that the elastic member can move more smoothly along the arc surface when the clamping assembly rotates, and the rotation resistance of the clamping assembly can be reduced.

[0020] Preferably, the elastic body is an elastic positioning bead.

[0021] Preferably, the welding device comprises at least two welding guns, and each welding gun is arranged in a circumferential array around the rotation axis of the clamping assembly.

[0022] In this scheme, at least two welding guns are arranged, so that at least two welding points can be welded on the insertion end of the optical fiber at the same time. Taking three welding guns as an example, when the three welding guns are arranged at equal angles around the clamping assembly, the three welding guns can first weld three equidistant welding points on the insertion end of the optical fiber, then rotate the clamping assembly, and the three welding guns can weld again, so that three equidistant welding points are formed on the insertion end of the optical fiber again. The clamping assembly is rotated once, and a total of six welding points are formed on the insertion end of the optical fiber, so that the welding is quickly completed. During this process, the positioning structure can be positioned only once to complete the welding, and the welding efficiency can be greatly improved.

[0023] Preferably, the clamping assembly is provided with a rotating handle.

[0024] In this scheme, the rotating handle is arranged, so that the operator can rotate the clamping assembly.

[0025] The beneficial effects of the utility model are as follows:

[0026] This invention features a positioning structure between the base and the clamping assembly. This structure positions the clamping assembly as it rotates, ensuring it remains stably stationary at a designated position. Accurate rotation of the optical device ensures precise welding of the welding torch. During welding, the positioning structure provides rotational resistance to the clamping assembly, preventing the optical device from rotating when the welding torch contacts it. This ensures accurate solder joint positioning, uniform force on the fiber optic insertion end, and stable connection to the optical device's housing. Attached Figure Description

[0035] The technical solution of this utility model will be clearly and completely described in conjunction with the accompanying drawings and through specific embodiments.

[0036] Example 1:

[0037] like Figure 1 and Figure 5As shown, the embodiment one provides a rotatable positionable welding device, which comprises a base 8, a clamping assembly 1 and a positioning structure. The clamping assembly 1 is rotatably connected with the base 8. The positioning structure is arranged between the clamping assembly 1 and the base 8. The positioning structure is used to position the rotation angle of the clamping assembly 1 and to form additional rotation resistance to the clamping assembly 1 when the clamping assembly 1 rotates a specified angle.

[0038] For example, the positioning structure comprises elastic bodies and positioning holes 6. The elastic bodies are arranged on the clamping assembly 1 and follow the rotation of the clamping assembly 1. The positioning holes 6 are arranged on the base 8. In the initial position of the clamping assembly 1, the elastic bodies are located in one of the positioning holes 6. At this time, the clamping assembly 1 needs to overcome the resistance of the elastic bodies moving out of the positioning hole 6 to rotate. When the clamping assembly 1 rotates, the elastic bodies move with the clamping assembly 1. The positioning holes 6 are located on the moving path of the elastic bodies. When the elastic bodies move to another positioning hole 6, the elastic bodies are clamped into the positioning hole 6 under the action of their own elastic force, resulting in an increase in the rotation resistance of the clamping assembly 1. The angles of the two positioning holes 6 relative to the rotation axis of the clamping assembly 1 are fixed. The operator can determine the rotation angle of the clamping assembly 1 according to the rotation resistance. At this time, the optical device clamped by the clamping assembly 1 can be welded. Because the clamping assembly 1 needs to overcome the resistance of the elastic bodies 3 moving out of the positioning hole 6 to rotate at this time, the contact between the welding torch 9 and the optical device will not cause the clamping assembly 1 to rotate, which can ensure that the welding torch 9 can weld and form a welding point at the accurate position.

[0039] As shown in Figure 3 and Figure 4 The elastic bodies can adopt elastic positioning beads on the market. Positioning supports 2 for installing the elastic positioning beads can be arranged on the clamping assembly 1. Threaded holes are arranged on the positioning supports 2. The elastic positioning beads are provided with external threads and are threadedly connected with the positioning supports 2. Alternatively, the elastic bodies can adopt elastic sheets. The elastic sheets are always in a force-bent state. The elastic sheets are stretched after entering the positioning holes 6 and are compressed after leaving the positioning holes 6. The resistance of the elastic sheets leaving the positioning holes 6 can form the rotation resistance of the clamping assembly 1.

[0040] A plurality of positioning holes 6 can be arranged in the circumferential direction of the clamping assembly 1. The elastic bodies 3 can cooperate with the plurality of positioning holes 6 respectively. The positioning holes 6 are distributed in a circumferential array along the rotation center of the clamping assembly 1, so that the included angles of any two adjacent positioning holes 6 relative to the rotation center of the clamping assembly 1 are the same. That is to say, with the rotation of the clamping assembly 1, the clamping assembly 1 rotates the same angle each time the elastic bodies enter the positioning holes 6. The welding torch 9 can perform welding once.

[0041] A guide groove 7 is arranged between the positioning holes 6, and the first positioning hole 6 and the last positioning hole 6 are communicated with each other through the guide groove 7 along the rotating direction of the clamping assembly 1. The guide groove 7 is an arc-shaped groove, and the center of the guide groove 7 coincides with the rotating center of the clamping assembly 1. When the clamping assembly 1 rotates, the elastic member 3 always moves along the guide groove 7. The overall shape of the guide groove 7 is an arc-shaped groove, because the guide groove 7 is always not combined into a whole circle, and there is no guide groove 7 between the last positioning hole 6 and the first positioning hole 6 along the rotating direction of the clamping assembly 1. That is to say, it is impossible to directly rotate from the last positioning hole 6 to the first positioning hole 6 along the rotating direction of the clamping assembly 1. It should be noted that, because the clamping assembly 1 can rotate clockwise and counterclockwise, the first positioning hole 6 and the last positioning hole 6 mentioned here refer to the positioning hole 6 at the end of the guide groove 7 in the rear direction of the rotating direction of the clamping assembly 1 in this rotation, and the positioning hole 6 at the other end of the guide groove 7 is the last positioning hole 6.

[0042] The elastic member 3 can only move in the guide groove 7, and when the elastic member 3 leaves the guide groove 7, it will exceed the compression limit of the elastic member 3, so that the elastic member 3 abuts against the plane where the guide groove 7 is located, thereby greatly increasing the rotating resistance of the clamping assembly 1, so that the clamping assembly 1 cannot rotate. Therefore, when the clamping assembly 1 cannot continue to rotate, the operator can know that the welding is completed, thereby avoiding repeated welding on the same position of the optical device.

[0043] The elastic member 3 can be arranged on the clamping assembly 1, and the positioning hole 6 is arranged on the base 8 at this time. Similarly, the elastic member 3 can also be arranged on the base 8, and the positioning hole 6 is arranged on the clamping assembly 1 at this time. When the elastic member 3 is clamped into the positioning hole 6, the clamping assembly 1 can still bring additional rotating resistance.

[0044] Still taking the example that the elastic member 3 is arranged on the clamping assembly 1.

[0045] The elastic member 3 can be arranged on the bottom surface of the clamping assembly 1, that is, the deformation direction of the elastic member 3 is downward, and the positioning hole 6 is arranged on the top surface of the base 8. The elastic member 3 can be clamped into the positioning hole 6 from top to bottom. At this time, the elastic member 3 can be directly installed on the bottom of the clamping assembly 1 by directly opening a hole on the bottom of the clamping assembly 1.

[0046] The elastic member 3 can also be arranged on the side surface of the clamping assembly 1, and at this time, a positioning block 4 needs to be arranged on the base 8. The positioning block 4 is located on one side of the clamping assembly 1, the positioning hole 6 is arranged on the positioning block 4, and the elastic member 3 moves along the side surface of the positioning block 4 close to one side of the clamping assembly 1.

[0047] As Figure 4As shown, the side of the positioning block 4 near the clamping assembly 1 is an arc-shaped surface, and the axis of the arc-shaped surface coincides with the rotation center of the clamping assembly 1, allowing the elastic element 3 to slide smoothly along the arc-shaped surface. Optionally, the guide groove 7 can be formed on the side of the positioning block 4 near the clamping assembly 1.

[0048] The positioning block 4 can be fixed to the base 8 by bolts or other fasteners.

[0049] The clamping assembly 1 can be a clamp used in the prior art to clamp and fix optical devices, so that the socket on the optical device for inserting the fiber optic cable is facing upwards. The bottom of the clamp is rotatably connected to the base 8. For example, a rotating hole is opened at the bottom of the clamp, and a rotating shaft is fixed on the base 8, so that the rotating hole is rotatably connected to the rotating shaft.

[0050] Alternatively, the clamping assembly 1 can be a combination structure of a clamp for clamping and fixing optical devices and a rotating block, as in the prior art. The clamp is connected to the top of the rotating block, the rotating block is provided with a rotating hole, and the base 8 is fixed with a rotating shaft, so that the rotating hole and the rotating shaft are rotatably connected.

[0051] Similarly, the rotating hole can be set on the base 8, while the rotating shaft can be set on the bottom of the fixture or the bottom of the rotating block.

[0052] The clamping assembly 1 has a rotating handle 5 on its side, which allows for easy rotation of the clamping assembly 1. The rotating handle 5 can be directly fixedly connected to the clamp or fixedly connected to the rotating block.

[0053] The connection between the rotating handle 5 and the clamping assembly 1 can be welding or threaded connection.

[0054] Example 2:

[0055] This embodiment two provides a rotating, positionable welding device. Unlike embodiment one, this embodiment two has at least two welding torches 9 on the base 8.

[0056] like Figure 5 As shown, each welding torch 9 is fixedly connected to the base 8, and the welding torches 9 are arranged in a circular array relative to the rotation center of the clamping assembly 1. After each welding torch 9 performs one welding operation, the clamping assembly 1 rotates, the positioning structure performs one positioning operation, and then each welding torch 9 performs welding again. Each positioning operation of the clamping assembly 1 by the positioning structure doubles the number of solder joints on the optical device. Therefore, using multiple welding torches 9 can significantly increase welding efficiency.

[0057] The more welding torches 9 there are, the higher the welding efficiency. The number of welding torches 9 can be two, three, or more.
