Description

Technical Field

[0001] The invention belongs to the technical field of mechanical production and processing, and in particular relates to a burr grinding device for mechanical production and processing. Background Art

[0002] In current mechanical processing, most steel plates will leave sharp and rough burrs on the steel plates after rolling and shearing, and the steel plates need to be deburred to facilitate subsequent processing of the steel plates.

[0003] The traditional burr treatment method is manual grinding, which causes serious dust and noise pollution in the workplace and is labor-intensive. The burr grinding device currently used places the workpiece on the conveyor belt when working, and then the servo motor drives the conveyor belt to start rotating. When the workpiece reaches the inside of the gantry, the infrared sensor senses the workpiece and sends a signal to the controller. The controller controls the servo motor to stop working, and the second hydraulic cylinder starts working. The workpiece is fixed under the grinding brush head through two fixing clamps. The second hydraulic cylinder is controlled by the pressure sensor to avoid damage to the workpiece. The first hydraulic cylinder starts working, and the motor starts to rotate, and then grinding is performed; however, the above-mentioned grinding device is not convenient for adjusting the relative position between the workpiece and the grinding brush head, resulting in a limited grinding plane, and it is impossible to achieve multi-directional grinding of the workpiece, and smoke is easy to escape outward during grinding.

[0037] The conveying rollers 2 are arranged in pairs on the housing 1, and adjacent conveying rollers 2 are connected by a conveyor belt 3.

[0038] The conveying roller 2 on one side is connected to an external motor through a coupling.

[0039] In one embodiment of the present invention, the machined workpiece is placed on the conveyor belt 3 during use, and the external motor drives the conveyor roller 2 at one end to rotate. The conveyor roller 2 also drives the conveyor roller 2 on the other side to rotate synchronously through the arranged conveyor belt 3, thereby conveying the workpiece from one end to the other end.

[0040] like Figure 1 As shown, as another preferred embodiment of the present invention, the grinding assembly includes a guide rail 4, a guide groove 5, a tool box 6, a grinding disc 7 and a stepping drive unit 8;

[0042] The guide rail 4 is provided with a guide groove 5 , and a stepping drive unit 8 is installed on the side of the tool box 6 for pushing the stepping drive unit 8 to slide along the guide rail 4 to adjust the position of the grinding disc 7 .

[0043] In one example of the present invention, the stepper drive unit 8 described in the present application includes a built-in micro motor, a traveling wheel and a control system. The stepper drive unit 8 can be set to make the tool box 6 and the grinding disc 7 slide along the guide rail 4, and during the sliding process, the built-in motor of the tool box 6 drives the grinding disc 7 to rotate synchronously, so as to grind and remove burrs on the workpiece passing the bottom.

[0044] like Figure 1 and Figure 3 As shown, as another preferred embodiment of the present invention, the lifting and adjusting assembly includes a driving screw 9, a movable block 10, a positioning column 11 and a synchronous belt 14;

[0045] The driving screws 9 are arranged in pairs and are both rotatably mounted on the housing 1. A pulley is mounted at the bottom end of the driving screw 9, and adjacent pulleys are connected by a synchronous belt 14.

[0046] A movable block 10 is installed on the driving screw 9 , a positioning column 11 is fixedly connected to the movable block 10 , and the positioning column 11 is slidably connected to the housing 1 .

[0047] In one example of the present invention, the driving motor 23 works and drives the driving screw 9 at the bottom to rotate. The driving screw 9 at this position drives the pulley at the bottom to rotate synchronously, and then drives the driving screw 9 on the other side to rotate synchronously through the synchronous belt 14, so that the movable block 10 and the positioning column 11 move in the height direction along the shell 1 to adjust the height direction position in the clamping state.

[0054] In one embodiment of the present invention, when in use, the air pump 16 draws in external air, sends it into the air pipe 20 along the gap between the outer tube 18 and the inner tube 19, and finally sprays it out from the nozzle 21. At the same time, the mixed air blown out by the vacuum cleaner 17 flows upward along the inside of the inner tube 19, and finally filters the smoke and dust when passing through the vacuum cleaner 17. In addition, the air pipe 20 described in the present application can be installed at the free end of the movable block 10 so that it can move synchronously with the workpiece.

[0055] In summary, the workpiece is placed on the conveyor belt 3, and the external motor drives the conveyor roller 2 at one end to rotate.

The movable block 10 can also be retracted to facilitate horizontal and lateral adjustment of the workpiece position. The drive motor 23 works and drives the driving screw 9 at the bottom to rotate. The driving screw 9 at this position drives the pulley at the bottom to rotate synchronously, and then drives the driving screw 9 on the other side to rotate synchronously through the synchronous belt 14, so that the movable block 10 and the positioning column 11 move in the height direction along the shell 1, so as to facilitate the adjustment of the height direction in the clamping state. The work station can drive the suction cup 13 and the workpiece between adjacent suction cups 13 to rotate through the set rotating disk 12, and can make the tool box 6 and the grinding disk 7 slide along the guide rail 4 through the set stepping drive unit 8, and in the process of sliding, the built-in motor of the tool box 6 drives the grinding disk 7 to rotate synchronously, and the workpiece passing through the bottom is polished and burred. The air pump 16 draws in external air and sends it into the air supply pipe 20 along the gap between the outer tube 18 and the inner tube 19, and finally sprays it out from the nozzle 21. At the same time, the air blown out by the vacuum cleaner 17 is mixed and flows upward along the inside of the inner tube 19, and finally the smoke and dust are filtered when passing through the vacuum cleaner 17.
