Description

TECHNICAL FIELD

[0001] The utility model relates to optical device processing technical field, specifically provide a concentric welding rotary table. 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, and an insertion end with a built-in optical element is arranged at the optical fiber end. The housing of the optical device is provided with a insertion hole. After the insertion end is inserted into the insertion hole, the insertion end is welded and connected with the housing. In order to ensure the stable connection of the insertion end and the housing, spot welding is performed in the circumferential direction of the insertion end.

[0003] However, because the size of the optical device is small, the welding precision is high. When welding is performed in the circumferential direction of the insertion end, a clamping assembly is usually used to fix the optical device, and a welding gun is installed on a welding table so that the position of the welding gun can be accurately welded at the connection position of the insertion end and the housing of the optical device. However, this welding mode needs to re-clamp the optical device after each welding, and welding is performed again on the insertion end and the housing of the optical device, thereby increasing the welding points. After repeated clamping and welding, a plurality of welding points are formed in the circumferential direction of the insertion end. Obviously, this repeated clamping and welding mode is complicated to operate, and has the problem of low welding efficiency. SUMMARY

[0004] The utility model provides a concentric welding rotary table, and is used to solve the problem of the complicated operation of the repeated clamping and welding mode of the existing optical device welding and the problem of low welding efficiency.

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

[0006] A concentric welding rotary table, comprising a base, a rotating part and a clamping part, the clamping part is arranged on the rotating part, the rotating part is rotatably connected with the base, and the clamping part is used for clamping an optical device. The insertion hole for inserting the optical fiber insertion end on the optical device is coaxial with the rotation axis of the rotating part.

[0007] In the present scheme, the clamping part for clamping the optical device is arranged on the rotating part, and the rotation axis of the rotating part is coaxial with the optical fiber insertion end. Therefore, after welding at one position of the optical device, the rotating part can be rotated, and the rotation of the rotating part drives the rotation of the clamping part, so that the optical device on the clamping part and the insertion end of the optical fiber are rotated. Since the rotation axis of the rotating part is coaxial with the insertion end, the welding gun can still be used to weld the connection position of the insertion end and the optical device after rotation. After the rotating part is rotated for several times, a plurality of welding points can be welded in the circumferential direction of the insertion end, so that the optical device and the insertion end are fixedly connected. During the welding process, the optical device does not need to be repeatedly clamped. After one welding point is welded each time, the rotating part only needs to be rotated, thereby simplifying the operation steps and improving the welding efficiency.

[0008] Preferably, the rotating part is a discoid structure or a regular polygon structure, and the rotating axis of the rotating part coincides with the axis of the discoid structure or the regular polygon structure.

[0009] In this scheme, the center of gravity of the discoid structure or the regular polygon structure coincides with the axis, so that the inclination of the rotating part caused by the deviation of the center of gravity can be avoided.

[0010] Preferably, the rotating part is a symmetrical block structure.

[0011] In this scheme, if other auxiliary structures need to be installed on the rotating part, the rotating part can be set as a symmetrical block structure, so that the center of gravity is in the middle and the inclination of the rotating part caused by the serious deviation of the center of gravity can be prevented.

[0012] As an optional scheme, the rotating part is provided with a rotating shaft, the base is provided with a rotating hole, and the rotating shaft is rotatably connected with the rotating hole.

[0013] As an optional scheme, the rotating part is provided with a rotating hole, the base is provided with a rotating shaft, and the rotating shaft is rotatably connected with the rotating hole.

[0014] Preferably, a positioning structure is arranged between the rotating part and the base, and the positioning structure is used for positioning the rotating angle of the rotating part.

[0015] In this scheme, the positioning structure is arranged between the rotating part and the base, and the positioning structure is used for stably stopping the rotating part at a position relative to the base. For example, after the rotating part is rotated by a certain angle, the positioning structure can be stably stopped, so that the rotating does not continue to occur during the welding process, and thus the spot welding can be stably formed.

[0016] Preferably, the positioning structure comprises an elastic member and a positioning hole, and the elastic member and the positioning hole are arranged on the rotating part and the base respectively.

[0017] In this scheme, when the elastic member moves to the positioning hole, the elastic member is popped out and clamped into the positioning hole, at this time, the rotating resistance of the rotating part will obviously increase, and the rotating part will not rotate under the action of no external force. Therefore, the elastic member can cooperate with the positioning hole to play a role of positioning the rotating part.

[0018] Preferably, the welding rotating table further comprises a driving mechanism, the driving mechanism is arranged on the base or the rotating part, and the driving mechanism is used for driving the rotating part to rotate.

[0019] In this scheme, the rotating table can be driven by the driving mechanism, so that the manual operation steps are reduced and the operation difficulty is reduced.

[0020] Preferably, the driving mechanism is arranged on the base, the rotating part is provided with a gear or a ring gear, and the driving mechanism is in transmission connection with the rotating part through the gear or the ring gear.

[0021] In the scheme, the gear transmission mode can ensure the rotation accuracy of the rotating part, thereby ensuring the rotation accuracy of the optical device and ensuring the welding accuracy.

[0022] Optionally, a rotating handle is arranged on the side of the rotating part.

[0023] In the scheme, the handle is arranged on the side of the rotating part, and the rotating part can be moved by manually pushing the handle.

[0024] The present application has the following beneficial effects:

[0025] The clamping part is arranged on the rotating part, the rotating part is rotated after one-time welding, the insertion end of the optical device and the optical fiber is rotated relative to the welding gun, and welding operation is performed again after rotation, so that multiple electric welding is performed in the circumferential direction of the insertion end of the optical fiber, the positions of the optical device and the insertion end of the optical fiber are adjusted by rotation, repeated clamping is not needed, and the welding efficiency is improved.

[0032] The technical scheme of the present application is clearly and completely illustrated by the specific implementation manner of the embodiment of the present application in combination with the drawings.

[0033] Embodiment one:

[0034] like Figure 1 As shown, this embodiment provides a concentric welding rotary table, including a base 1, a rotating part 3, and a clamping part 5. The rotating part 3 is rotatably mounted on the base 1, and the clamping part 5 is fixedly connected to the rotating part 3. When the rotating part 3 rotates relative to the base 1, the clamping part 5 is used to clamp optical devices. When the clamping part 5 rotates, the optical devices clamped on the clamping part 5 rotate synchronously. The optical devices have insertion holes for installing optical fibers. The insertion end of the optical fiber has the same diameter as the insertion hole, and the axis of the insertion end of the optical fiber is coaxial with the insertion hole. After the clamping part 5 clamps the optical device, the insertion end of the optical fiber is coaxial with the rotation axis 4 of the rotating part 3. A welding torch is fixed on the base 1. The welding torch can be mounted on the base 1 through a fixed bracket, and the position of the welding torch relative to the base 1 remains unchanged. Because the axis of the fiber optic insertion end is coaxial with the rotation axis of the rotating part 3, the distance between the welding gun and the fiber optic insertion end remains unchanged after the rotating part 3 rotates. As the rotating part 3 rotates, the welding gun can perform electric welding in the circumferential direction of the fiber optic insertion end. The rotating part 3 can also be rotated during the welding process, thus forming a full weld at the connection between the fiber optic insertion end and the optical device housing. When electric welding is required, the rotating part 3 only needs to rotate a certain angle and then stop rotating before the welding gun performs another weld, thus forming a weld point in the circumferential direction of the fiber optic insertion end. By repeatedly rotating and welding, multiple coaxial weld points can be formed in the circumferential direction of the optical device.

[0035] The base 1 is a platform structure for mounting the rotating part 3 and the welding torch. A mounting bracket for the welding torch can be fixed to the base 1 using bolts or other fasteners. The rotating part 3 has a rotating shaft 4 at its bottom, and the base 1 has a rotating hole; the rotating shaft 4 is rotatably connected to the rotating hole. Alternatively, the rotating part 3 has a rotating hole, and the base 1 has a rotating shaft 4, which is rotatably connected to the rotating hole.

[0036] The top surface of the base 1 is a plane, and the welding torch and the rotating part 3 are both located on the top surface of the base 1. The bottom surface of the rotating part 3 is provided with a rotating shaft 4, and the clamping part 5 is connected to the top surface of the rotating part 3. The rotating shaft 4 of the rotating part 3 is parallel to the vertical plane.

[0037] The center of gravity of the rotating part 3 coincides with the axis of rotation. The rotating part 3 is preferably disc-shaped due to its low manufacturing cost. The rotating part 3 can also be a regular polygon, such as a square, equilateral triangle, or regular pentagon. However, regular polygons are expensive to manufacture, so a disc-shaped structure is preferred.

[0038] When the rotating part 3 adopts a disc-shaped structure, the rotating shaft 4 is coaxial with the disc-shaped structure.

[0039] like Figure 3As shown, if other structures need to be installed on the rotating part 3, the rotating part 3 can be set as a block structure symmetrical to left and right, which can facilitate the installation of other structures and keep the center of gravity in the middle. For example, the rotating part 3 includes a rectangular block, opposite sides of the rectangular block are respectively provided with mounting plates 9 for installing other structures, the mounting plates 9 on the two sides of the rectangular block are of the same size, so that the center of gravity of the rotating part 3 is still in the middle.

[0040] When the welding gun spot-welds the connection between the insertion end of the optical fiber and the shell of the optical device, each spot-welding position needs to be equidistantly distributed, so that the insertion end of the optical fiber and the shell of the optical device are uniformly stressed, and the connection between the insertion end of the optical fiber and the shell of the optical device is stable. Therefore, the positioning structure is arranged between the rotating part 3 and the base 1, the rotating angle of the rotating part 3 is determined through the positioning structure, and the angle is not measured every time the rotating part 3 rotates, so that the efficiency of determining the rotating angle of the rotating part 3 can be improved.

[0041] As shown in Figure 2 The positioning structure can include an elastic member and a positioning hole 8 matched with the elastic member. The elastic member and the positioning hole 8 are arranged on the rotating part 3 and the base 1 respectively. When the elastic member is arranged on the rotating part 3, the positioning hole 8 is arranged on the base 1; when the elastic member is arranged on the base 1, the positioning hole 8 is arranged on the rotating part 3.

[0042] The elastic member can be an elastic positioning bead or a spring sheet, and the elastic positioning bead is a part available on the market.

[0043] Taking the case that the elastic positioning bead is arranged on the rotating part 3 as an example. The elastic positioning bead is arranged on the bottom surface of the rotating part 3, and the positioning hole 8 is arranged on the moving path of the elastic positioning bead. When the rotating part 3 rotates, the elastic positioning bead moves. When the elastic positioning bead moves to the positioning hole 8, the elastic positioning bead pops out and is clamped into the positioning hole 8. At this time, the rotating resistance of the rotating part 3 will obviously increase, and at this time, it can be known that the rotating part 3 has rotated a fixed angle, and the next welding can be performed.

[0044] When multiple spot-welding is needed, multiple positioning holes 8 can be arranged, for example, multiple positioning holes 8 are arranged on the moving path of the elastic positioning bead, and each positioning hole 8 is arranged at an equal angle relative to the rotating axis of the rotating part 3. The elastic positioning bead is clamped into the positioning hole 8 once, and welding is performed once. Finally, the welding points are equiangularly distributed in the circumferential direction of the insertion end of the optical fiber.

[0045] When welding, the rotating part 3 rotates in a fixed direction, for example, counterclockwise or clockwise. Along the rotating direction of the rotating part 3, the first positioning hole 8 and the last positioning hole 8 are provided with a guide groove 7, the depth of the guide groove 7 is less than the depth of the positioning hole 8, and the elastic positioning bead is located in the guide groove 7 and moves along the guide groove 7. When the elastic positioning bead moves to the position of the positioning hole 8, the elastic positioning bead will be clamped into the positioning hole 8. That is, during the movement of the elastic positioning bead, the elastic positioning bead does not contact the opening of the guide groove 7.

[0046] The guide groove 7 can constrain the maximum angle of rotation of the rotating part 3. When the elastic positioning bead moves to the end of the guide groove 7, the elastic positioning bead cannot continue to move, and the operator can know that the welding is completed. By constraining the travel of the elastic positioning bead through the guide groove 7, it can prevent the rotating part 3 from rotating more than 360° and causing repeated welding.

[0047] Optionally, a positioning block can be provided on one side of the rotating part 3, the guide groove 7 and the positioning hole 8 are arranged on the positioning block, and the elastic body 6 is installed on the rotating part 3 through a fixed support, so that the elastic body 6 is inserted into the guide groove 7 and can move along the guide groove 7.

[0048] A rotating handle 2 is provided on one side of the rotating part 3, and the operator can hold the rotating handle 2 to rotate the rotating part 3. In order to reduce the influence of the rotating handle 2 and the elastic positioning bead on the center of gravity of the rotating part 3, the rotating handle 2 and the elastic positioning bead are respectively arranged on opposite sides of the rotating part 3, and the weights of the rotating handle 2 and the elastic positioning bead are balanced. At the same time, the rotating part 3 can be made of heavy metal, and the weight of the rotating part 3 can be increased to reduce the influence of the weights of the rotating handle 2 and the elastic positioning bead, so that the rotation of the rotating part 3 is more stable.

[0049] The clamping part 5 is used to clamp the optical device and make the insertion hole of the optical device face upward, so that the welding gun can weld from the side. There are clamps that can clamp optical devices in the prior art. For example, a positioning groove can be provided on the optical device clamp, the top end of the positioning groove penetrates the optical device clamp, a top pressing screw hole is formed on one side of the positioning groove, and a top pressing bolt is used to press the shell of the optical device from the side to fix the optical device. The positioning groove is arranged in a vertical direction, and a limiting block is arranged on the lower end of the groove bottom and protrudes from the groove bottom. When the optical device is clamped, the bottom end of the shell of the optical device can abut against the limiting block from top to bottom, thereby positioning the optical device in the height direction and preventing the optical device from sliding downward along the positioning groove.

[0050] Embodiment two:

[0051] The embodiment two provides a concentric welding rotating table, which is different from the embodiment one in that the embodiment two is provided with a driving mechanism, and the rotating part 3 is driven to rotate through the driving mechanism.

[0052] The driving mechanism is arranged on the base 1, and the driving mechanism is in transmission connection with the rotating shaft 4 at the bottom of the rotating part 3, for example, the driving mechanism is in gear transmission connection with the rotating shaft 4.

[0053] The driving mechanism can adopt a servo motor or a stepping motor. A controller is configured for the servo motor or the stepping motor, the servo motor or the stepping motor is controlled by the controller to rotate a fixed angle each time. The welding gun can also be electrically connected with the controller, after the servo motor or the stepping motor stops rotating, the controller controls the welding gun to weld, after the welding of the welding gun stops, the controller controls the servo motor or the stepping motor to rotate. The driving mechanism and the welding gun are controlled by the controller, which can improve the welding efficiency.

[0054] The bottom surface of the rotating part 3 can be directly machined into a gear ring, and the driving mechanism can be directly in transmission connection with the gear ring at the bottom surface of the rotating part 3.
