Chinese Patent Announcement No. CN205218788U, announced on May 11, 2016, discloses a method that can automatically polish the concave-convex surface of the hyperbolic arc surface, the radian and size of the processed arc surface can be adjusted arbitrarily, and the hyperbolic arc surface can be automatically adjusted The impact of the arch height difference on the grinding head is high, and the processing efficiency is high, which can be applied to mass-produced double-arc surface polishing machines. However, this kind of curved surface automatic polishing machine can only automatically polish the curved surface of small workpieces, and cannot be used for large workpieces.

Utility model content

In order to solve the above technical problems, the utility model designs a curved surface automatic polishing machine for large workpieces.

The utility model adopts the following technical solutions:

An automatic polishing machine for curved surfaces, including a workbench and a control system. The two sides of the workbench are respectively fixed with guide rails parallel to each other in the front and rear directions. The two guide rails are equipped with a gantry that can move back and forth along the guide rails. The gantry is provided with A main shaft that can move laterally along the gantry frame. A cylinder is fixed downward inside the main shaft. A rotary motor is fixed at the end of the output shaft of the cylinder. A polishing wheel is fixedly connected to the output shaft of the rotary motor. The four corners of the bottom of the main shaft are respectively fixed downwards. A laser sensor is arranged, a pressure sensor is arranged between the main shaft and the cylinder, and the cylinder, the rotating motor, the pressure sensor and the laser sensor are connected to the control system through wires.

Preferably, a moving motor is arranged in the gantry, and a moving wheel is arranged between the gantry and the guide rail. The moving motor controls the rotation of the moving wheel to drive the gantry to move back and forth, and the moving motor is connected to the control system through a wire.

Preferably, a main shaft motor is arranged inside the main shaft, and a moving wheel is arranged between the main shaft and the gantry frame. The main shaft motor controls the rotation of the moving wheel to drive the main shaft to move laterally, and the main shaft motor is connected to the control system through wires.

Preferably, a control box is fixedly installed on one side of the gantry, a control system is connected inside the control box, and a control platform is fixedly installed outside the control box.

Compared with the prior art, the four corners of the bottom of the main shaft of the curved surface automatic polishing machine are respectively fixed with laser sensors in the downward direction. When all four laser sensors fail to illuminate the workpiece 7, the main shaft is automatically lifted to a high place. The gantry moves forward in the forward and backward direction. When any one of the laser sensors encounters the workpiece, the main shaft descends. When the polishing wheel touches the workpiece, the pressure sensor senses the pressure. When the pressure reaches the preset pressure, the cylinder locks the pressure. The laser sensor locks the light feedback distance. The gantry moves along the front and back directions, and the main shaft determines the slope of the workpiece according to the distance fed back by the laser sensor, thereby adjusting the up and down of the main shaft. When the pressure sensed by the main shaft decreases, the main shaft moves a set distance in the lateral direction, and the gantry moves in the front and rear direction again. So as to achieve the purpose of polishing the workpiece evenly under uniform pressure by the polishing wheel. Through the curved surface automatic polishing machine, the texture direction of the polished workpiece surface is consistent, and the roughness is uniform, which improves the quality and efficiency of product polishing and reduces labor costs.

detailed description

Below by specific embodiment, in conjunction with accompanying drawing, the technical scheme of the utility model is described further in detail:

Embodiment: As shown in accompanying drawing 1, a curved surface automatic polishing machine includes a workbench 1 and a control system. The two sides of the workbench are respectively fixed with mutually parallel guide rails 2 arranged in the front and rear directions. The gantry 3 that the guide rail moves back and forth, the gantry is provided with a main shaft 4 that can move laterally along the gantry, a cylinder is fixedly arranged downward inside the main shaft, a rotating motor is fixedly installed at the end of the output shaft of the cylinder, and the output shaft of the rotating motor is fixedly connected There is a polishing wheel 6, and laser sensors 5 are respectively fixed in the downward direction at the four corners of the bottom of the main shaft, and a pressure sensor is arranged between the main shaft and the cylinder. There is a moving motor, a moving wheel is set between the gantry and the guide rail, the moving motor controls the rotation of the moving wheel to drive the gantry to move forward and backward, the moving motor is connected to the control system through a wire, a main shaft motor is installed in the main shaft, and a moving wheel is set between the main shaft and the gantry The main shaft motor controls the rotation of the moving wheel to drive the main shaft to move laterally. The main shaft motor is connected to the control system through wires. A control box is fixed on one side of the gantry, connected to the control system inside the control box, and a control platform is fixed outside the control box.

The four corners of the bottom of the main shaft of the curved surface automatic polishing machine are respectively fixed with laser sensors in the downward direction. When the four laser sensors fail to illuminate the workpiece 7, the main shaft is automatically lifted to a high place, and the gantry moves forward along the front and rear directions. Walking, when any one of the laser sensor feedback meets the workpiece, the spindle will drop, and when the polishing wheel touches the workpiece, the pressure sensor will sense the pressure. When the pressure reaches the preset pressure, the cylinder will lock the pressure, and the laser sensor will lock the light feedback distance. The gantry moves along the front and back directions, and the main shaft determines the slope of the workpiece according to the distance fed back by the laser sensor, thereby adjusting the up and down of the main shaft. When the pressure sensed by the main shaft decreases, the main shaft moves a set distance in the lateral direction, and the gantry moves in the front and rear direction again. So as to achieve the purpose of polishing the workpiece evenly under uniform pressure by the polishing wheel.

The above-described embodiment is only a preferred solution of the utility model, and does not limit the utility model in any form. There are other variations and improvements without exceeding the technical solution described in the claims. type.
