Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical device processing technology, and specifically provides a welding turntable assembly. Background Technology
[0002] When connecting optical devices to optical fibers, welding is a common processing method. To connect the optical fiber to the optical device, an insertion end for a built-in optical element is provided at the fiber end. The housing of the optical device has a socket; after the insertion end is inserted into the socket, it is welded to the housing. To ensure a stable connection between the insertion end and the housing, spot welding is performed on the circumference of the insertion end.
[0003] Therefore, a clamping part can be used to hold and fix the optical device, and then the clamping part is fixed to a rotatable rotating part. The rotation axis of the rotating part is coaxial with the insertion hole, and a fixed welding gun is set on one side of the rotating part. The welding gun is used to weld the insertion end of the optical device on the clamping part to the housing of the optical device. After one welding, the angle of the optical device can be changed by rotating the rotating part. After rotating a certain angle, welding can be repeated. After multiple rotations and welding, multiple solder points can be formed in the circumferential direction of the insertion end of the optical device.
[0004] However, during use, it was found that the rotating part tilts at an angle when it rotates, especially when rotated manually. Because the optical device is very small, this tilting of the rotating part causes a significant displacement of the device's position, ultimately leading to misalignment of the solder joint. This prevents an effective solder joint between the fiber optic insertion end and the device's housing, resulting in an unstable connection between the fiber optic insertion end and the device's housing. Utility Model Content
[0005] This utility model provides a welding turntable assembly to solve the problem that when the rotating part rotates, the angle will tilt, causing the welding position to shift, making it impossible to form an effective weld between the fiber optic insertion end and the housing of the optical device, resulting in an unstable connection between the fiber optic insertion end and the housing of the optical device.
[0006] The technical solution of this utility model is as follows:
[0007] A welding turntable assembly includes a base, a rotating part, and a constraint structure. The rotating part is rotatably disposed on the base, and the constraint structure is disposed between the rotating part and the base. The constraint structure is used to constrain the rotating part from the top and bottom to prevent the rotating part from tilting.
[0008] In this design, the upper and lower sides of the rotating part are constrained by the constraint structure, preventing the rotating part from rotating horizontally and tilting vertically. This solves the problem of optical device displacement caused by tilting during rotation. Since the rotating part does not tilt, the optical device will not shift its position, ensuring accurate welding in each weld and a stable connection between the fiber optic insertion end and the optical device housing after welding.
[0009] Preferably, it includes at least two constraint structures, each of which is arranged in a circumferentially distributed manner in the circumferential direction of the rotating part.
[0010] In this scheme, setting multiple constraint structures can further increase the accuracy of the constraint effect and ensure that the rotating part remains horizontal during rotation.
[0011] Preferably, the constraint structure includes a constraint block, and a constraint groove is provided on the side of the constraint block near the rotating part. The two sides of the constraint groove are respectively attached to the top and bottom surfaces of the rotating part to prevent the rotating part from tilting.
[0012] In this solution, the rotating part is constrained by a constraint groove. The contact area between the constraint groove and the rotating part is large, and the constraint effect is improved by increasing the contact area.
[0013] Preferably, it includes two constraint structures, which are respectively disposed on opposite sides of the rotating part.
[0014] In this scheme, two constraint structures are set to constrain the rotating part from both sides. The rotating part is constrained by the constraint grooves on both sides, which can further improve the constraint effect.
[0015] The rotating part moves by rotation. Due to the installation accuracy of the constraint block, the edge of the rotating part may abut against the bottom of the constraint groove, causing the rotating part to jam. To address this, the rotating part is also equipped with a buffer structure. The buffer structure has a buffering and expansion function along the radial direction of the rotating part and is located between the rotating part and the roller.
[0016] In this design, the buffer structure can buffer the expansion and contraction along the radial direction of the rotating part. When the buffer structure contacts the bottom of the constraint groove, the buffer structure can shorten, which can prevent the rotating part from getting stuck with the constraint groove.
[0017] To address the issue of excessive friction between the buffer structure and the bottom of the constraint groove affecting the rotation of the rotating part, the rotating part is equipped with rollers. The rollers are in rolling connection with the constraint groove, and the two end faces of the rollers are respectively in contact with the two sides of the constraint groove.
[0018] In this design, the rotating part contacts the bottom of the constraint groove through rollers, and the rolling friction between the rollers and the constraint groove can reduce the rotational resistance of the rotating part.
[0019] Preferably, the buffer structure is a buffer plunger, which includes a plunger rod, a plunger cylinder and a buffer spring. One end of the plunger rod is rotatably connected to a roller, and the other end of the plunger rod is slidably connected to the plunger cylinder. The spring is disposed inside the plunger cylinder, and both ends of the buffer spring abut against the plunger rod and the plunger cylinder respectively.
[0020] In this design, the buffer rod and plunger cylinder can constrain the buffer direction, ensuring that the buffer structure only moves in the radial direction of the rotating part, without affecting the constraint effect of the constraint groove on the vertical direction of the rotating part.
[0021] Preferably, the constraint block is provided with a strip-shaped hole, and the constraint block is connected to the base by fasteners such as bolts passing through the strip-shaped hole.
[0022] In this design, the slotted holes allow for greater installation error, and the slotted holes facilitate the installation of the constraint blocks.
[0023] Preferably, a rotating handle is provided on one side of the rotating part.
[0024] In this design, a rotating handle is provided to facilitate the operator's rotation of the rotating part.
[0025] Preferably, the base is provided with a limiting rod, which is used to constrain the movement range of the rotating handle, and limiting rods are provided on both sides of the rotating handle.
[0026] In this design, the rotation angle of the rotating part can be constrained by a limiting rod. When the rotating handle abuts against the limiting rod, the rotating part cannot continue to rotate. The position of the limiting rod can be used to determine the rotation angle of the rotating part. For example, when the positions of the two limiting rods are fixed, the rotation angle of the rotating part is fixed when the rotating handle rotates from one limiting rod to the other. Therefore, by simply setting the relative positions of the two limiting rods, it can be ensured that the rotation angle of the rotating part is fixed each time.
[0027] The beneficial effects of this utility model are:
[0028] This invention incorporates a constraint structure that restrains the rotating part from both the top and bottom, thus preventing it from tilting. With the rotating part fixed, the optical device's position remains unchanged, ensuring accurate welding every time and guaranteeing a stable connection between the fiber optic insertion end and the optical device's housing.

[0034] The technical solution of this utility model will be clearly and completely described in conjunction with the accompanying drawings and through specific embodiments.
[0035] Example 1:
[0036] like Figure 1 As shown in the figure, this embodiment provides a welding turntable assembly, including a base 1, a welding torch, a rotating part 2, a clamping part, and a constraint structure. The rotating part 2 is rotatably disposed on the top surface of the base 1. The welding torch is fixedly connected to the base 1 and disposed on one side of the rotating part 2. The clamping part is connected to the top surface of the rotating part 2. The clamping part is used to clamp optical devices, and the welding torch is used to weld optical devices. The constraint structure is connected to the base 1 and abuts against the upper and lower sides of the rotating part 2, thereby constraining both the upper and lower sides of the rotating part 2 and preventing the rotating part 2 from tilting.
[0037] The base 1 is a platform structure for mounting the rotating part 2 and the welding torch. A mounting bracket for the welding torch can be fixed to the base 1 using bolts or other fasteners. The base 1 can have a rotating hole adapted to the rotating part 2, allowing the rotating part 2 to be rotatably connected to the rotating hole. Alternatively, a bearing can be installed inside the rotating hole, and the rotating part 2 can have a rotating shaft connected to the bearing. Using a bearing allows for smoother rotation of the rotating part.
[0038] The top surface of the base 1 is a plane, and both the welding torch and the rotating part 2 are located on the top surface of the base 1. The bottom surface of the rotating part 2 is provided with a rotating shaft, and the clamping part is connected to the top surface of the rotating part 2. The rotation axis of the rotating part 2 is parallel to the vertical plane.
[0039] The center of gravity of the rotating part 2 coincides with the axis of rotation. The rotating part 2 is a block structure with left and right symmetry, which facilitates the installation of other structures while keeping the center of gravity in the center. For example, the rotating part 2 includes a rectangular block, and mounting plates for installing other structures are respectively provided on opposite sides of the rectangular block. The mounting plates on both sides of the rectangular block are the same size, so that the center of gravity of the rotating part 2 remains in the center.
[0040] The constraint structure can be a constraint block 6, which is fixedly connected to the base 1 by bolts or other fasteners. A constraint groove 5 is provided on the side of the constraint block 6 near the rotating part 2, with the opening of the constraint groove 5 facing the rotating part 2. Both ends of the constraint groove 5 extend through both sides of the constraint block 6. The bottom of the constraint groove 5 is an arc-shaped surface, and the center of the bottom of the constraint groove 5 coincides with the rotation center of the rotating part 2. The upper and lower sides of the constraint groove 5 are respectively in contact with the upper and lower sides of the rotating part 2, thus constraining the rotating part 2 from both sides and preventing the rotating part 2 from tilting.
[0041] At least two constraint structures can be provided in the circumferential direction of the rotating part 2. For example, constraint structures can be provided on opposite sides of the rotating part 2; or, three, four or more constraint structures can be provided along the circumferential direction of the rotating part 2.
[0042] The larger the contact area between the constraint structure and the rotating part 2, the better the constraint effect; a single constraint structure can achieve the same effect as constraining the rotating part 2. If the contact between the constraint structure and the rotating part 2 is point contact, then two or more constraint structures are required to achieve the desired constraint effect.
[0043] A rotating handle 8 is provided on one side of the rotating part 2, and the operator can hold the rotating handle 8 to rotate the rotating part 2.
[0044] The base 1 is provided with two limiting rods 9, the bottom ends of which are threadedly connected to the base 1. The two limiting rods 9 are positioned on both sides of the rotating handle 8, and the rotating handle 8 can only move between the two limiting rods 9. Multiple threaded holes for connecting with the limiting rods 9 can be provided on the base 1. By connecting the limiting rods 9 to different threaded holes, the range of motion of the rotating handle 8 can be changed, thereby changing the rotation range of the rotating part 2.
[0045] The constraint groove 5 obstructs the handle 8. Multiple welding torches can be mounted on the base 1. When welding is required, multiple torches simultaneously weld the optical device. After welding, the handle 8 is rotated to turn the rotating part 2, allowing for another welding operation. This setup allows for multi-point welding in two passes, quickly forming multiple weld points on the circumference of the fiber optic insertion end. It also allows for uniform weld points to be formed on the circumference of the fiber optic insertion end even when the rotating part 2 can only rotate at a small angle. The number of welding torches can be two, three, four, or more.
[0046] The constraint block 6 is provided with a strip hole 7, and the constraint block 6 is connected to the base 1 by fasteners such as bolts passing through the strip hole 7.
[0047] A clamping part for holding optical devices can be installed on the top of the rotating part 2. As an optional embodiment, a positioning groove can be provided on the clamping part, with the top of the positioning groove penetrating the clamping part. A tightening screw hole is then opened on one side of the positioning groove, and a tightening bolt is used to press the housing of the optical device from the side, thus fixing the optical device. The positioning groove is arranged vertically, and a limit block is provided at the lower end of the bottom of the positioning groove, protruding from the bottom of the groove. When clamping the optical device, the bottom end of the optical device's housing can abut against the limit block from top to bottom, thereby positioning the optical device in the height direction and preventing the optical device from sliding downwards along the positioning groove.
[0048] Example 2:
[0049] This embodiment two provides a welding turntable assembly. Unlike embodiment one, the rotating part 2 in this embodiment two is also provided with a buffer structure 3 on its side.
[0050] The buffer structure 3 is fixedly connected to the rotating part 2, and the buffer structure 3 can only extend and retract in the radial direction of the rotating part 2 for buffering. One end of the buffer structure 3 is inserted into the constraint groove 5, and the two sides of the constraint groove 5 abut against the upper and lower sides of the buffer structure 3 respectively. The constraint groove 5 constrains the position of the buffer structure 3 from the upper and lower sides, thereby achieving the effect of constraining and buffering the rotating part 2.
[0051] The buffer structure 3 can be a buffer plunger. The buffer plunger includes a plunger rod, a plunger cylinder, and a buffer spring. One end of the plunger rod is rotatably connected to the roller 4, and the other end of the plunger rod is slidably connected to the plunger cylinder. The spring is disposed inside the plunger cylinder, and both ends of the buffer spring abut against the plunger rod and the plunger cylinder, respectively.
[0052] When the distance between the bottom of the constraint groove 5 and the rotation axis of the rotating part 2 is reduced due to low installation accuracy of the constraint structure, the buffer structure 3 abuts against the bottom of the constraint groove 5. The buffer structure 3 can retract inward along the radial direction of the rotating part 2, thereby preventing the constraint groove 5 from jamming with the rotating part 2.
[0053] Example 3:
[0054] This embodiment three provides a welding turntable assembly. Based on embodiment two, but unlike embodiment two, this embodiment three also includes rollers 4.
[0055] like Figure 2As shown, roller 4 is disposed at the end of buffer structure 3, and roller 4 is in rolling connection with constraint groove 5. The two sides of constraint groove 5 are respectively in contact with the two end faces of roller 4, and the two sides of constraint groove 5 constrain the position of roller 4 from the upper and lower sides respectively. By constraining the position of roller 4, the rotating part 2 is constrained to prevent the rotating part 2 from tilting.
[0056] The roller 4 can reduce the friction between the buffer structure 3 and the constraint groove 5, and reduce the resistance to the rotation of the rotating part 2.
