[0021] See also Figures 1 to 3 In the embodiment of the utility model, an automatic clamping welding tool for an elevator guide shoe seat includes a carrier plate 1 and a clamping station arranged on the carrier plate 1. Among them, there are two clamping stations, which are arranged on the top shell wall of the carrier plate 1 in a left-right symmetrical manner. The setting of the two clamping stations enables the orderly loading and unloading operation of the workpiece to be quickly realized when processing the workpiece, avoiding waiting when loading and unloading the workpiece, and further improving the processing efficiency of the workpiece.

[0022] The clamping station is composed of an end fixed clamp 2, a side calibration piece 3, an end movable clamp 4 and a cylinder 5. The end fixed clamp 2 and the end movable clamp 4 are arranged symmetrically front and back. The side calibration piece 3 is located at the side position between the end fixed clamp 2 and the end movable clamp 4. The side setting of the side calibration piece 3 allows the workpiece to be pre-calibrated during assembly, thereby ensuring the accuracy of its position when it is clamped and positioned, and ensuring the accuracy of subsequent welding processing.

[0023] The cylinder 5 is fixedly connected to the top of the carrier plate 1 and is located in front of the end movable clamp 4, and the output end of the cylinder 5 is fixedly connected to the end movable clamp 4. The arrangement of the cylinder 5 enables the end movable clamp 4 to automatically realize displacement drive, thereby completing the clamping and positioning of the workpiece to be processed.

[0024] The carrier plate 1 is provided with workstations symmetrically on the left and right sides, and each clamping station is loaded in the corresponding workstation. Each workstation is provided with a through slot that penetrates the carrier plate 1 symmetrically in front and back. The side calibration piece 3 is fixedly connected to the top shell wall of the carrier plate 1 by bolts, and the side calibration piece 3 is located in the middle of the symmetrical through slot. The through slot is convenient for placing the workpiece in the clamping station. The side calibration piece 3 is composed of an L-shaped plate and a wing plate, wherein the wing plate is fixedly connected to the L-shaped plate to further improve the stability of its setting.

[0025] The end clamping member 2 includes a horizontal plate 21 fixedly connected to the top shell wall of the carrier plate 1 by screws. A triangular plate 22 is fixedly connected to both sides of the top of the horizontal plate 21, and the front sides of the plurality of triangular plates 22 are commonly connected to an end clamping plate 23 for pressing against the side end of the workpiece. The horizontal plate 21 is located at the rear side of the rear through slot, and the bottom of the end clamping plate 23 passes through the rear through slot, and a convex plate for supporting the workpiece is symmetrically arranged on the left and right.

[0026] The end movable clamp 4 is composed of a slide rail 41, a slide plate 42, a second triangular plate 43 and a second end clamp plate 44. The slide rails 41 include two, both of which are fixedly connected to the top shell wall of the carrier plate 1 by bolts. The two slide rails 41 are respectively located on the left and right sides of the front through slot.

[0027] Both ends of the bottom of the slide plate 42 are fixedly connected with sliders by bolts, and the multiple sliders are respectively slidably connected to the corresponding slide rails 41. The sliding connection of the sliders on the slide rails 41 realizes the guiding support for the movement of the slide plate 42.

[0028] The second triangular plate 43 includes two pieces, which are symmetrically arranged on the top shell wall of the slide plate 42. The second end clamp plate 44 is fixedly connected to the rear shell wall of the symmetrical triangular plate 43. The bottom of the second end clamp plate 44 passes through the front through slot, and is symmetrically arranged with ear plates for supporting workpieces. The output end of the cylinder 5 is fixedly connected to the slide plate 42 by bolts.

[0029] Holes are provided in a matrix on the end clamp plate 1 23 and the end clamp plate 2 44, and holes are also provided symmetrically on the side wall of the L-shaped plate. Each hole is provided with an elastic member for buffering the end face of the workpiece, thereby avoiding rigid contact with the workpiece and causing deformation of the workpiece when contacting the workpiece.

[0030] The convex plate on the end clamping plate 23 and the ear plate on the end clamping plate 2 44 are arranged to further improve the supporting effect when clamping and positioning the workpiece, thereby ensuring the stability of the workpiece positioning.

[0031] The working principle of the utility model is: when welding a workpiece, first place the workpiece to be processed in any clamping station, and when the cylinder 5 in the clamping station is running, the corresponding end movable clamp 4 is moved, thereby achieving the clamping and positioning of the workpiece. Then the welding robot performs welding operation on the clamped workpiece, and during the welding process, the workpiece to be processed is installed in another idle clamping station. Then, when the previous workpiece is processed, the welding robot is adjusted to the workpiece to be processed loaded on another station, and the workpiece is welded. After adjusting the welding robot, the staff takes the processed workpiece out of the clamping station and assembles the workpiece to be processed inside it. The cycle is repeated, thereby achieving rapid processing of the workpiece.

[0032] The end movable clamp 4 in the clamping station clamps and positions the workpiece with the operation of the cylinder 5. The operation of the cylinder 5 causes the slide plate 42 in the end movable clamp 4 to move along the slide rail 41 in cooperation with the slider, thereby driving the displacement of the end clamp plate 2 44 connected with the triangle plate 2 43. After the movement, the end clamp plate 2 44 approaches the end of the workpiece, and when it contacts the workpiece, it pushes the workpiece with the continuous movement of the cylinder 5, so that the other end of the workpiece is pressed against the end fixed clamp 2, thereby clamping and fixing the end of the workpiece.

[0033] When the workpiece is loaded and placed in the clamping station, the side of the workpiece is close to the side calibration piece 3, thereby ensuring the accuracy of the workpiece placement in the clamping station and facilitating the subsequent accurate welding processing operation.

[0034] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
