Description

Technical Field

[0001] The present application relates to the technical field of deburring of plate processing, and in particular to a device for deburring the surface of a plate. Background Art

[0002] Plate cutting can be done in different ways depending on the thickness and material of the plate. For example, mechanical cutting uses mechanical tools (such as saw blades, knives, etc.) to apply force on the plate to cut it into the desired size and shape. Common mechanical cutting equipment includes band saws, circular saws, shears, etc. Laser cutting uses high-energy laser beams to cut plates, or plasma cutting uses the high temperature and high energy generated by plasma to cut plates, etc.

[0003] In the prior art, after the plate is cut, burrs generally appear on the cut edge of the plate. In order to improve the appearance and safety of use, the staff usually uses a grinding wheel to grind the edge of the plate. In the prior art, for machine automated grinding, a mobile device generally controls the grinding wheel to grind according to a predetermined trajectory.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the above-mentioned grinding method is generally comprehensive grinding, that is, regardless of whether there are burrs on other parts of the plate, it will be ground. For plates with burrs only on the cut surface, this method will undoubtedly greatly prolong the grinding time, thereby reducing the grinding efficiency.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0007] The present application provides a device for deburring the surface of a plate, which adopts the following technical solution: a device for deburring the surface of a plate, comprising a fixed frame for supporting the entire device, the upper part of the fixed frame is provided with a driving mechanism for fixing and controlling the plate for moving and grinding, both sides of the upper end of the fixed frame are rotatably provided with a laying mechanism for attaching sandpaper to the edge of the cut surface of the plate for grinding, and a supporting mechanism is also provided below the laying mechanism to provide sufficient supporting force for the laying mechanism.

[0008] Preferably, the fixing frame comprises an upper frame, four supporting legs are fixedly provided on the bottom edge of the upper frame, and a bracket for installing the driving mechanism is also provided on the upper part of the upper frame.

[0009] Preferably, the driving mechanism includes a motor 1 fixed to the upper part of the bracket, the output shaft of the motor 1 is connected to a cylinder, the output shaft of the cylinder is connected to a U-shaped fixing sleeve, and locking bolts are threadedly arranged on both sides of the U-shaped fixing sleeve.

[0010] Preferably, the laying mechanism comprises a support plate rotatably arranged at the bottom of the upper frame, a guide rod is rotatably arranged at both ends of the support plate, and two retracting and releasing units for retracting and releasing sandpaper are symmetrically arranged on the back side of the support plate.

[0011] Preferably, the retracting and releasing unit includes a mounting seat rotatably arranged on the back side of the support plate, and a socket for inserting a sandpaper roller is rotatably arranged on one side of the mounting seat, wherein a sprocket is arranged between two sockets, a chain is arranged between the two sprockets, and a motor 2 is arranged on one of the mounting seats, and the output shaft of the motor 2 is connected to one of the sockets.

[0012] Preferably, the support mechanism comprises a support plate fixedly arranged between four support legs, four return springs are obliquely arranged on the support plate, and the return springs are fixedly connected to the side surfaces of the corresponding mounting seats.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. By setting a driving mechanism and a laying mechanism, the part of the plate with burrs can be fixed downwards, the laying mechanism below is used to lay sandpaper, and the supporting mechanism is used to provide support for the sandpaper when it contacts the plate, ensuring that there is sufficient friction between the sandpaper and the edge of the plate.

[0023] Reference Figure 1 The driving mechanism 2 includes a motor 201 welded on the upper part of the bracket, and the output shaft of the motor 201 is connected to a cylinder 202, and the output shaft of the cylinder 202 is connected to a U-shaped fixing sleeve, and locking bolts 204 are threadedly installed on both sides of the U-shaped fixing sleeve; by inserting one end of the plate into the U-shaped fixing sleeve, and then rotating the locking bolts 204 on both sides to fix the plate, the cylinder 202 drives the plate to move up and down to contact and rub with the sandpaper belts on both sides below, and the friction end face of the plate is switched by the motor 201.

[0024] Reference Figure 1 - Figure 4The laying mechanism 3 includes a support plate 401301 rotatably mounted on the bottom of the upper frame, a guide rod 302 is rotatably mounted on both ends of the support plate 401301, and two retracting units 303 for retracting and releasing sandpaper are symmetrically mounted on the back of the support plate 401301, and the retracting unit 303 includes a mounting seat 3031 rotatably mounted on the back of the support plate 401301, and a holder 3032 for inserting a sandpaper roller is rotatably mounted on one side of the mounting seat 3031, wherein a sprocket 3033 is mounted between the two holders 3032, a chain 3034 is sleeved between the two sprockets 3033, and a second motor 3035 is mounted on one mounting seat 3031, and the output shaft of the second motor 3035 is connected to one of the holders 3032; The belt roller wrapped with the sandpaper belt is installed between the two mounting seats 3031 on the back of the support seat, and a receiving roller for winding the sandpaper belt is installed between the other two mounting seats 3031.
