[0028] The nailing fixture 11 includes a horizontal plate 112, a vertical plate 110 and a reinforcing rib 111. The vertical plate 110 is vertically arranged on the horizontal plate 112. The reinforcing rib 111 is arranged at the position where the horizontal plate 112 and the vertical plate 110 are connected. The vertical plate 110 is connected to the nailing device 12, and the horizontal plate 112 is connected to the moving end of the moving mechanism 10. The moving mechanism is an XY module. The lifting mechanism is a lifting cylinder.

[0030] The positioning mechanism includes a cylinder support 6, a push block and a plurality of positioning cylinders 7. When the nailing device 12 performs a nailing operation on the workpiece 1, the positioning cylinder 7 provides reliable support for the workpiece 1 through the push block to avoid position deviation caused by the gravity of the workpiece 1 or external force. It effectively avoids the shaking or vibration of the workpiece 1 during the nailing process, and improves the nailing accuracy and stability. The design of multiple positioning cylinders 7 enables the positioning mechanism to have a certain adjustment ability. Driven by the cylinder, the push block can automatically adjust the support position and angle according to the size and shape of the workpiece 1 to meet the needs of workpieces 1 of different specifications.

The fixed structure includes a locating pin and a clamping cylinder 3. The workpiece 1 is connected to the loading platform 23 through the locating pin.

[0032] The rotating structure 2 includes a rotating platform 21 and two loading platforms 23, and the loading platforms 23 are symmetrically arranged and perpendicular to each other. When one loading platform 23 is in the nailing station, the other loading platform 23 can be used to place or remove the workpiece 1. The rotation realizes the alternating operation of multiple stations, reduces the waiting time, and improves the overall efficiency of the equipment, which is particularly suitable for mass production. The rotating platform 21 is tilted (the tilt angle is 45°) so that the loading platform 23 forms a certain angle relative to the vertical axis of the equipment.

Avoid displacement or shaking of the workpiece 1 during rotation, and ensure that the workpiece 1 is always in the correct position during nailing.

[0033] How this example works

[0034] Step 1: The operator places the workpiece 1 on the loading platform 23, aligns the positioning pin with the predetermined hole position of the workpiece 1, and fixes the workpiece 1 using the clamping cylinder 3. After the clamping cylinder 3 is started, ensure that the workpiece 1 is firmly clamped to avoid shaking or displacement in subsequent operations.

[0035] Step 2: Start the equipment, the driving device 4 drives the rotating platform 21 to rotate, and moves the workpiece 1 on the loading platform 23 to the nailing position. The inclined design (45° angle) of the rotating platform 21 ensures that the workpiece 1 enters the nailing area at the best angle. At the same time, the multiple positioning cylinders 7 in the positioning mechanism support the bottom of the workpiece 1 through the push block, further fix the position of the workpiece 1, and ensure its vertical alignment with the nailing device 12.

[0036] Step 3: The lifting mechanism is started to adjust the working position of the entire nailing device 12 to a height suitable for the current workpiece 1. The lifting bracket 8 (including the horizontal plate 112 and the vertical plate 110) is supported by the reinforcing ribs 111 to ensure the stability of the device during the height adjustment process and prevent shaking.

[0037] Step 4: The moving mechanism 10 drives the nail fixing frame 11 to move, and the nailing device 12 is aligned with the specific nailing position of the workpiece 1 to complete the precise positioning.

[0038] Step 5: The nailing device 12 is started to nail the threaded hole of the workpiece 1. The nailing device 12 is ensured to remain perpendicular to the surface of the workpiece 1 during the whole process to avoid nailing failure due to angle deviation. The push block of the positioning mechanism supports the workpiece 1. After nailing is completed, the positioning mechanism and the lifting mechanism are recovered.

[0039] Step 6: Check the nailing results

[0040] After nailing is completed, the system automatically detects whether the installation depth, position and angle of the nails meet the requirements.

[0041] Step 7: After nailing is completed, the driving device 4 is started again, and the rotating platform 21 rotates 180° to move the nailed workpiece 1 out of the nailing area, and at the same time, a new workpiece 1 on another loading platform 23 is sent into the nailing area to start the next round of operation.

[0042] Step 8: The operator or the robot arm takes out the nailed workpiece 1 from the loading platform 23 and performs subsequent processing or assembly as required.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
