Description

Technical Field

[0001] This utility model relates to a welding mechanism for an automatic assembly machine for seat armrest tubes and nuts. Background Technology

[0002] For some chair armrests, to facilitate connection and fixation with other chair components, embedded nuts are usually installed at the ends of the armrest tubes. Screws are passed through the corresponding components and then screwed into the embedded nuts to secure the armrest tubes to the relevant components. However, the current method of assembling embedded nuts on armrest tubes typically involves manually stamping the embedded nuts into the armrest tubes using a positioning mold, followed by manual welding. This manual welding process is cumbersome, resulting in low production efficiency and jeopardizing worker safety. Utility Model Content

[0003] The purpose of this utility model is to provide a welding mechanism for an automatic assembly machine of seat armrest tubes and nuts, including a worktable and a welding structure. The welding mechanism includes a support base, a welding torch, and a clamp. The support base is fixed on the worktable, and the clamp is movably mounted on the support base along an X-axis and a Y-axis. The Y-axis is perpendicular to the X-axis. The clamp includes two vertical plates and two clamping blocks respectively mounted on the two vertical plates. The welding torch is clamped between the two clamping blocks. The clamping blocks are connected and fixed to the vertical plates by a first screw. The vertical plates are provided with a first strip-shaped hole extending along a Z-axis. The first screw passes through the first strip-shaped hole and is screwed and fixed to the clamping block. The first screw can move up and down along the first strip-shaped hole to adjust the fixed height of the clamping block. The Z-axis is perpendicular to the plane where the X-axis and Y-axis intersect.

[0004] The clamp and the support are provided with a first driving mechanism for driving the clamp to move along the X-axis and a second driving mechanism for driving the clamp to move along the Y-axis.

[0006] The welding mechanism further includes a clamp and a stand; the stand is fixed on the worktable, and the clamp is movably mounted on the stand along the Z-axis; the clamp is used to clamp or release the handrail pipe; a third drive mechanism for driving the clamp to move is provided between the clamp and the stand; the third drive mechanism is connected and fixed to the stand by a second screw; the stand is provided with a second strip hole extending along the Z-axis, the second screw passes through the second strip hole and is screwed and fixed to the third drive mechanism, and the second screw can move up and down along the second strip hole to adjust the fixed height of the third drive mechanism.

[0007] All clamps are pneumatic grippers; the first and second drive mechanisms are linear modules; and the third drive mechanism is a cylinder.

[0008] The clamp of this utility model has a clamping block whose height can be adjusted up and down along the first strip hole to finely adjust the position of the welding gun relative to the port of the handrail tube; the clamp moves along the X-axis to move closer to or further away from the handrail tube reaching the welding station, and the clamp moves along the Y-axis to weld and fix the two sides of the nut inside the port of the handrail tube.

The welding mechanism includes a support base 31, a welding torch 32, and a clamp.

[0014] The support base 31 is fixed on the workbench 1, and the clamp is movably mounted on the support base 31 along an X-axis and a Y-axis; the Y-axis is perpendicular to the X-axis; the clamp includes two upright plates 33 and two clamping blocks 34 respectively mounted on the two upright plates 33, and the welding torch 32 is clamped between the two clamping blocks 34; the clamping blocks 34 are connected and fixed to the upright plates 33 by a first screw 341; the upright plate 33 is provided with a first strip hole extending along a Z-axis, the first screw 341 passes through the first strip hole and is screwed and fixed to the clamping block 34, and the first screw 341 can move up and down along the first strip hole to adjust the fixed height of the clamping block 34; the Z-axis is perpendicular to the plane where the X-axis and Y-axis intersect.

[0015] The clamping base of this technical solution has a clamping block 34 whose height can be adjusted up and down along the first strip hole to finely adjust the position of the welding gun 32 relative to the port of the handrail tube; the clamping base moves along the X-axis to move closer to or further away from the handrail tube reaching the welding station, and the clamping base moves along the Y-axis to weld and fix the two sides of the embedded nut in the port of the handrail tube.

[0016] This technical solution uses a welding mechanism to automatically weld and fix the embedded nuts installed in the port of the handrail pipe, which can improve production efficiency and ensure the safety of workers.

[0017] A first drive mechanism 35 for driving the clamp to move along the X-axis and a second drive mechanism 36 for driving the clamp to move along the Y-axis are provided between the clamp and the support 31.

[0018] The clamp is mounted on the first drive mechanism 35, and the first drive mechanism 35 is mounted on the second drive mechanism 36. The bottom of the second drive mechanism 36 is provided with a screw 361 extending along the Z-axis, which is perpendicular to the plane where the X-axis and Y-axis intersect. The screw 361 passes through the through hole of the support base 31 and can move up and down along the through hole. On both sides of the through hole, there are limiting nuts 362 that are screwed to the screw 361 to fix the height of the screw 361.

[0019] Specifically, one end of the support base 31 is connected and fixed to the workbench 1 so that the other end of the support base 31 is suspended in the air, allowing the screw 361 to pass through.

[0020] The second drive mechanism 36 of this technical solution is mounted on the support base 31 via a screw 361, and the height of the clamp can be adjusted by adjusting the height of the screw 361.

[0022] This technical solution uses a clamp 37 to clamp the handrail tube during welding. The clamp 37 can move along the Z-axis. When the handrail tube reaches the welding station, it rises to clamp the handrail tube. After the welding is completed, the handrail tube is released and moved away from the handrail tube, without affecting the handrail tube's transport to the next station.

[0023] The third drive mechanism 39 can be adjusted in height along the Z-axis direction, thereby adjusting the position of the clamp 37 to correspond with the position of the handrail tube, so as to accurately grasp the handrail tube.

[0024] All of the clamps 37 are pneumatic grippers, i.e., pneumatic fingers.

[0025] The first drive mechanism 35 and the second drive mechanism 36 are linear modules.

[0026] The third drive mechanism 39 is a cylinder.
