DETAILED DESCRIPTION

[0017] In order to more clearly illustrate the technical solution implemented by the present invention, the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] See Figure 1-2 , an anti-pinch automatic tightening machine, including a frame 1, a tightening head 2, a workbench 3, an operating table 4, and a base 5;

[0019] See Figure 1-2 The frame 1 is mounted above the base 5, the tightening head 2 is suspended below the frame 1, the workbench 3 is mounted on the base 5, and is located below the tightening head 2. The workbench 3 is provided with an anti-pinch fixture 31, and the operating table 4 is mounted on the side of the base 5. The operating table 4 is equipped with a control panel and a PLC controller, the control panel is connected to the PLC controller, and the PLC controller is connected to the anti-pinch fixture 31 and the frame 1. The operating table 4 controls the slider and the telescopic rod on the frame 1 to control the tightening head 2 to move along the three-axis direction on the workbench 3, so that the tightening head 2 can work at various positions in the space.

[0020] See Figure 1-2The frame 1 includes a support rod 11, an X-axis electric slide 12, an X-axis slider 13, a Y-axis electric slide 14, a Y-axis slider 15, and a telescopic connecting rod 16. The support rod 11 is vertically fixed on the base 5, the X-axis electric slide 12 is mounted on the support rod 11, the X-axis slider 13 is installed on the X-axis electric slide 12, both ends of the Y-axis electric slide 14 are fixed on the X-axis slider 13, and the Y-axis slider 15 is installed on the Y-axis electric slide 14. The frame 1 is mounted above the base 5 and is divided into XY-axis sliders and electric slides, which can move the tightening head 2 to any position on the workbench 3, increase the flexibility of the tightening head 2, and facilitate operation during automatic tightening.

[0021] See Figure 1-2 The tightening head 2 is installed below the Y-axis slider 15 through an electric telescopic connecting rod 21. The electric telescopic connecting rod 21 controls the tightening head 2 to move up and down on the Z-axis, making it easier for the tightening head 2 to adapt to different working conditions and enhancing the convenience of using the tightening head 2.

[0022] See Figure 1-2 The anti-pinch fixture 31 includes a hydraulic cylinder 311, a hydraulic rod 312, and a contact piece 313. The hydraulic cylinder 311 is symmetrically installed side by side in the middle of the workbench 3 on both sides. The hydraulic rod 312 extends from the hydraulic cylinder 311, and the contact piece 313 is installed at the outer end of the hydraulic rod 312 through a rotating shaft. A protective sponge is installed on the side of the contact piece 313 that contacts the workpiece. The anti-pinch fixture 31 adopts multiple clamps on both sides. When clamping and fixing the workpiece, there is no need to consider the fixed position or shape of the workpiece. It has strong adaptability to various workpieces and does not require manual adjustment of the workpiece, which reduces the risk of clamping. The protective sponge can also reduce the damage caused by clamping.

[0023] See Figure 1-2 The PLC controller is respectively connected to the X-axis electric slide 12, the Y-axis electric slide 14, the electric telescopic connecting rod 21 and the hydraulic cylinder 311. The use of the PLC controller can quickly and accurately control the automatic tightening machine to work, thereby accelerating the workpiece processing efficiency.

[0024] See Figure 1-2 , parts boxes 32 are provided on both sides of the workbench 3, and the parts boxes 32 are filled with screws and other parts required for assembly, which is convenient for fast loading and replacement of parts during assembly and tightening.

[0025] According to the above embodiment, the working process of the utility model is as follows:

[0026] Place the parts required for workpiece assembly into the parts box 32 on the workbench, start the operating table 4, place the workpiece to be assembled on the workbench 3, and operate the operating table 4 to control the anti-pinching clamp 31 to clamp and fix the workpiece. When clamping and fixing, there is no need to adjust the workpiece to a fixed position. Since the contact piece 313 and the hydraulic rod 312 are connected by a rotating shaft, the contact piece 313 automatically adapts to the contour and position of the workpiece, and there is no need to manually adjust the position of the workpiece. After the workpiece is clamped and fixed, the tightening head 2 is controlled by the operating table 4 to take out the required parts from the parts box 32, and the parts are assembled on the workpiece through the tightening head 2. After the assembly is completed, the anti-pinching clamp 31 is released through the operating table 4, and the workpiece is removed before assembling the next workpiece.
