Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a safe laser spot welding fixture. Background Technology

[0002] In the existing technology, the laser spot welding fixtures used for optical transceivers mostly have a flat plate structure on the bottom. When the fixture with the optical transceiver is placed on the laser spot welding worktable, if the worktable is not flat or clean enough, the fixture will tilt, making the laser spot welding operation difficult and increasing the risk of safety accidents caused by improper operation by the operator.

[0003] Secondly, an uneven fixture may cause the laser beam's focal point to deviate from the intended position, increasing the difficulty of laser beam control. If the laser beam cannot be precisely controlled, it may cause harm to the surrounding environment and operators. Furthermore, an uneven fixture can lead to workpiece position deviation, affecting welding quality. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a safe laser spot welding fixture to solve the technical problem that the fixture in the prior art is prone to tilting due to unevenness and insufficient cleanliness of the worktable, which increases the risk of safety accidents caused by improper operation by the operator.

[0005] This utility model is achieved through the following technical solution:

[0006] A safe laser spot welding fixture includes a support A and a support B, and a fixture body rotatably mounted between the two supports, the fixture body being suspended in the air, and a level being mounted on the top surface of the fixture body.

[0007] The support B has a receiving cavity, and a rotating shaft is fixedly provided at one end of the clamp body near the support B. The rotating shaft extends into the receiving cavity and is rotatably connected to the support B. A cam is fixedly provided outside the shaft that extends into the receiving cavity.

[0008] The cavity is equipped with a toggle mechanism that can make the cam swing around the pivot, and the support A is equipped with a support mechanism for adjusting the height of the support A.

[0009] Furthermore, the outer circumferential surface of the cam is provided with a through groove along its center line, and the actuating mechanism includes a paddle block with its upper end extending into the groove. The bottom of the paddle block is integrally formed with a transmission block, and the transmission block is slidably connected to the bottom wall of the receiving cavity.

[0010] The bottom of the transmission block is provided with a transmission groove, and the two ends of the transmission groove are obliquely arranged along the two diagonal directions of the transmission block. A drive rod is inserted into the transmission groove, and the bottom of the drive rod is fixedly connected to the drive block.

[0011] The support B has a mounting groove that communicates with the receiving cavity, allowing the drive block to move in a direction perpendicular to the support B, and a drive component for driving the drive block to move along the mounting groove is installed in the mounting groove.

[0012] Furthermore, the driving component includes a mounting plate fixedly connected to the outward opening of the mounting groove, a lead screw rotatably connected to the mounting plate, the lead screw extending into the mounting groove and threadedly connected to the driving block, and a knob A fixedly provided at the outward end of the lead screw.

[0013] Furthermore, two protrusions are arranged opposite each other at the opening of the groove along the center line of the cam. The protrusions are integrally formed with the cam, and the side of the lever facing the protrusion has an arc-shaped groove.

[0014] Furthermore, the support mechanism includes a lug fixedly connected to the support A, a screw threaded vertically onto the lug, and a knob B and a washer fixedly connected to the upper and lower ends of the screw, respectively.

[0015] Furthermore, a sealing plate for sealing the cavity is fixedly connected to the top opening of the cavity.

[0016] Furthermore, the top surface of the fixture body is provided with several placement slots.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. Regarding the relative position of the fixture on the laser spot welding worktable, when the bubble on the level is too far forward or too far back, the cam is rotated by the actuating mechanism, which in turn drives the rotating shaft to rotate, causing the fixture body to pitch and rotate. By finely adjusting the angle of the fixture body, the front and back of the fixture body can be kept in a horizontal state.

[0019] When the bubble of the level is too far forward or too far back, the support height of the support A can be finely adjusted by the support mechanism so that both ends of the fixture body are in a horizontal state. This ensures that the fixture is placed horizontally on the laser spot welding worktable. The horizontally placed fixture makes operation easier, reduces operator fatigue and misoperation, thereby reducing safety accidents caused by improper operation and improving welding quality.

[0020] 2. Since the clamp body is suspended between the two supports, the contact area between the clamp body and the workbench can be reduced by suspending the clamp body. This reduces the interference caused by unevenness or lack of cleanliness of the workbench on the horizontal installation of the clamp. In addition, the weight of the clamp is reduced as a whole, which reduces the safety hazards caused by the operator's physical exertion and unstable holding. Attached Figure Description

[0030] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a safe laser spot welding fixture, including a support A1 and a support B2, and a fixture body 3 suspended between the two supports. By suspending the fixture body 3, the contact area between the fixture body 3 and the worktable surface can be reduced, thereby reducing the interference caused by unevenness or insufficient cleanliness of the worktable surface on the horizontal installation of the fixture.

[0031] Please see Figure 1 and Figure 2 The top surface of the fixture body 3 is equipped with a level 4. In this application, the level 4 is a bubble level. By observing whether the bubble in the level 4 is centered, it can be determined whether the fixture body 3 is in a horizontal position. The top surface of the fixture body 3 is provided with several placement slots 31. The optical transceiver is aligned and inserted into the placement slots 31 to complete the installation of the object to be spot welded.

[0032] Please see Figure 1 and Figure 3 The support B2 has a receiving cavity 5, and a sealing plate 10 for sealing the receiving cavity 5 is fixedly connected to the top opening of the receiving cavity 5 to prevent external debris or impurities from entering the receiving cavity 5.

[0033] The clamp body 3 is rotatably mounted between two supports. A rotating shaft 6 is fixed at one end of the clamp body 3 near the support B2. The rotating shaft 6 extends into the receiving cavity 5 and is rotatably connected to the support B2. The side of the clamp body 3 near the support A1 is rotatably connected in the same way, so that the clamp body 3 can pitch and rotate between the two supports. A cam 7 is fixed outside the shaft 6 that extends into the receiving cavity 5.

[0034] Please see Figure 3 and Figure 4 The cavity 5 is equipped with a toggle mechanism 8 that can make the cam 7 swing around the pivot 6. Specifically, the outer circumferential surface of the cam 7 has a through groove 71 along its center line. The toggle mechanism 8 includes a toggle block 81 with its upper end extending into the groove 71. The bottom of the toggle block 81 is integrally formed with a transmission block 82. The transmission block 82 is slidably connected to the bottom wall of the cavity 5. The width of the transmission block 82 is adapted to the width of the cavity 5.

[0035] The bottom of the transmission block 82 is provided with a transmission groove 83. The two ends of the transmission groove 83 are obliquely arranged along the two diagonal directions of the transmission block 82. A drive rod 84 is inserted into the transmission groove 83. A drive block 85 is fixedly connected to the bottom of the drive rod 84.

[0036] The support B2 has a mounting groove 86 that communicates with the receiving cavity 5 and allows the drive block 85 to move in a direction perpendicular to the support B2. A drive component 87 for driving the drive block 85 to move along the mounting groove 86 is installed in the mounting groove 86.

[0037] Please see Figure 1 , Figure 3 and Figure 4 The driving component 87 includes a mounting plate 871 fixedly connected to the outward opening of the mounting groove 86. A lead screw 872 is rotatably connected to the mounting plate 871. The lead screw 872 passes through a bearing on the mounting plate 871, extends into the mounting groove 86, and is threadedly connected to the driving block 85. A knob A873 is fixedly provided at the outward end of the lead screw 872. By turning the knob A873, the lead screw 872 is driven to rotate, thereby driving the driving block 85 to move along the mounting groove 86. When the driving block 85 moves, it drives the driving rod 84 to slide along the transmission groove 83. Since the transmission groove 83 is inclined at the bottom of the transmission block 82, the transmission direction can be changed, so that when the driving rod 84 moves, it can drive the transmission block 82 to slide along the length direction of the receiving cavity 5.

[0038] When the transmission block 82 slides, the cam 7 is rotated by the cooperation of the push block 81 and the groove 71, which in turn drives the rotating shaft 6 to rotate, causing the clamp body 3 to pitch and rotate, and finely adjusting the angle of the clamp body 3 to ensure that the clamp body 3 is horizontal.

[0039] Please see Figure 3 Two protrusions 72 are arranged opposite each other at the opening of the groove 71 along the center line of the cam 7. The protrusions 72 are integrally formed with the cam 7. The depth of the groove 71 can be extended by the protrusions 72 to ensure that the lever 81 continuously acts on the cam 7. The side of the lever 81 facing the protrusions 72 has an arc-shaped groove 811. The arc-shaped groove 811 can avoid the protrusions 72 when the lever 81 moves, which is beneficial for the lever 81 to turn the cam 7.

[0040] Please see Figure 2 The support A1 is equipped with a support mechanism 9 for adjusting the height of the support A1. The support mechanism 9 includes a lug 91 fixedly connected to the support A1, and a screw 92 vertically threaded onto the lug 91. A knob B93 and a rubber pad 94 are fixedly connected to the upper and lower ends of the screw 92, respectively. Specifically, by rotating the screw 92 through the knob B93, the support height of the support A1 can be finely adjusted so that both ends of the clamp body 3 are horizontal.

[0041] The working principle of this utility model is as follows: The optical transceivers are placed in the placement slots 31 on the fixture body 3. After placement, the fixture is placed on the laser spot welding worktable. The position of the bubble on the level 4 is observed to determine whether the fixture body 3 is in a horizontal state.

[0042] Regarding the relative placement of the clamp, when the bubble on the level 4 is positioned forward or backward, the screw 872 is rotated by turning the knob A873, which in turn drives the drive block 85 to move along the mounting groove 86. When the drive block 85 moves, it drives the drive rod 84 to slide along the transmission groove 83. Since the transmission groove 83 is inclined at the bottom of the transmission block 82, the transmission direction can be changed, so that when the drive rod 84 moves, it can drive the transmission block 82 to slide along the length direction of the receiving cavity 5.

[0043] When the transmission block 82 slides, the cam 7 is turned by the cooperation of the push block 81 and the groove 71, which in turn drives the rotating shaft 6 to rotate, causing the clamp body 3 to pitch and rotate. By finely adjusting the angle of the clamp body 3, the clamp body 3 can be kept in a horizontal position.

[0044] When the bubble of the level 4 is too far forward or too far back, the screw 92 can be rotated by the knob B93 to finely adjust the support height of the support A1, so that both ends of the fixture body 3 are in a horizontal state, thereby allowing the fixture to be placed horizontally on the laser spot welding worktable, ensuring that the welding work is carried out normally and safely.

[0045] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
