DETAILED DESCRIPTION

[0025] Embodiment 1

[0026] like Figure 1-Figure 2As shown, a clamp proposed by the utility model includes an operating table 1, a vertical plate B7, a turntable 8, a pressure detector 9, a control component and a support component 13. A vertical plate A2 is arranged on the operating table 1, and the vertical plate A2 is rotatably connected to the clamping plate A3. A motor A4 for driving the clamping plate A3 to rotate is arranged on the vertical plate A2. The vertical plate B7 is slidably connected to the operating table 1, and a linear drive component 6 for driving the vertical plate B7 to move toward the vertical plate A2 is arranged on the operating table 1. A guide groove 101 is arranged on the operating table 1, and the linear drive component 6 is located in the guide groove 101. The linear drive component 6 drives and connects the slider 5, and the vertical plate B7 is connected to the slider 5. The vertical plate A2 and the vertical plate B7 are at the same height. The linear drive assembly 6 includes a motor B, a screw rod and a slide rod. The screw rod and the slide rod are parallel and both are located in the guide groove 101. Both ends of the screw rod are rotatably connected to the operating table 1. The slide rod is connected to the inner wall of the guide groove 101. The screw rod and the slide rod both penetrate the slider 5, and the screw rod is spirally connected to the slider 5. The output end of the motor B is connected to the end of the screw rod. The turntable 8 is rotatably connected to the vertical plate B7, and the turntable 8 is connected to the clamping plate B10. The turntable 8 is slidably connected to a plurality of limit rods A11, each of which is distributed in a ring array about the axis of the turntable 8. The limit rod A11 is connected to the clamping plate B10, and the outer portion of the limit rod A11 is sleeved with a spring A12, and the two ends of the spring A12 are respectively in contact with the turntable 8 and the clamping plate B10. The pressure detector 9 is connected to the turntable 8 and the clamping plate B10. The control assembly is connected to the pressure detector 9 and the linear drive assembly 6 to automatically control the linear drive assembly 6 to stop working when the pressure detected by the pressure detector 9 reaches a certain value. The two groups of support assemblies 13 are connected to the vertical plate A2 and the vertical plate B7 respectively, so as to change the spacing between the support assemblies 13 on both sides following the movement of the vertical plate B7, and the support assembly 13 lifts the metal parts placed on its support parts to be between the clamping plate A3 and the clamping plate B10 in the working state. The support assembly 13 includes a limit rod B131, a spring B132, a base 133, a lifting drive assembly A134 and a support plate 135. The limit rod B131 on the two groups of support assemblies 13 is slidably connected to the vertical plate A2 and the vertical plate B7 respectively, the limit rod B131 is connected to the base 133, and the base is connected to the lifting drive assembly A134. The lifting drive assembly A134 includes but is not limited to a scissor lift, and the scissor lift drives the support plate 135 connected to the corresponding side. The spring B132 is sleeved on the outside of the limit rod B131 and abuts against the clamping plate and the base 133 on the corresponding side.

[0027] In this embodiment, firstly, according to the length of the metal workpiece, the motor B is started, and the motor B drives the screw to rotate, thereby driving the slider 5 and the vertical plate B7 to move to the distance between the clamping plate A2 and the clamping plate B10 suitable for placing the metal workpiece, and then the metal workpiece is placed on the support plates 135 on both sides, and the scissor lifts on both sides are started to rise synchronously to lift the workpiece to between the clamping plates on both sides, and then the clamping plates on both sides are close to each other and pressed against the workpiece, and the pressing force is detected and judged according to the pressure detector 9, so that the control component can directly control the motor B to pause by sending a pressure signal back to the control component. After the workpiece is clamped, the support plate 135 is lowered in height. Since the distance between the clamping plates on both sides is smaller than the distance between the vertical plate A2 and the vertical plate B7, the support plate 135 after the height is lowered can place the next workpiece, so that after the current workpiece is processed and removed, it can be directly pushed up and supplemented, saving the processing waiting time. When the length of the metal part is small, even when the support plates 135 on both sides are squeezed, the bases 133 on both sides can slide freely and squeeze the corresponding side springs B132. When the clamp is away from the reset, the support plate 135 will also automatically reset under the tension of the spring B132. This structure makes the utility model suitable for clamping workpieces of different lengths, and after clamping the workpiece, the workpiece can be flipped by starting the motor A4 to facilitate uniform processing of the circumference of the workpiece without manual surface changing, saving time and effort.

A negative pressure collection component 20 for collecting debris generated during the grinding process is also provided on the operating table 1, and the input end of the negative pressure collection component 20 is connected to the inside of the guide groove 101. The negative pressure collection component includes a storage box 2001, a storage box 2002, a filter 2003 and a fan 2004.

Then the linear module B14 and the hydraulic cylinder are started to adjust the grinding wheel position so that the grinding wheel contacts the outer surface of the metal workpiece, and the grinding wheel rubs against the metal surface to remove the burrs and rust spots on the surface of the workpiece. The linear module A14 controls the movable grinding wheel to move horizontally. At the same time, after the surface is cleaned, the motor A4 controls the turntable A2 and the workpiece to flip to an appropriate angle, and continues to drive the grinding wheel to reciprocate and grind to achieve surface treatment of each surface of the workpiece. During the grinding process, the debris follows the airflow along the guide groove 101 and the guide tube into the storage box 2001, and the debris is blocked by the filter 2003 and retained in the storage box 2002, while the air is directly discharged by the fan 2004. This structure effectively avoids the splashing of debris and ensures a clean and tidy operating environment.
