[0002] Usually, a set of robotic automated grinding systems consists of different mechanical units such as robots, grinders, polishers, loading tables, etc. The stability of the system and the production of products with relatively high requirements mainly depend on the robot program and grinding tools (grinding machines). Due to the inconsistency of products, there will be certain differences in the surface effects after a batch of products are processed.

[0003] Currently, there are only relatively simple springs as pressure control and relatively expensive servo systems as force control systems on the market. However, these two types of spring compensation cannot set the force online. When the spring is in use, if it bends excessively, especially in rotation or rotating applications, it will cause excessive deformation of the spring, damage the material structure of the spring, and cannot maintain a constant pressure. Summary of the invention

[0005] The grinding force control mechanism includes a control box, and a steering mechanism is arranged on the outer side of the control box. When the steering mechanism positions the outer side of the control box, the position of the control box is adjusted, the grinding angle and position of the grinding mechanism are adjusted, and the swing angle of the part is dynamically adjusted. The control box is provided with a telescopic mechanism inside, and the telescopic mechanism pushes the part laterally to control the grinding pressure of the part to avoid unevenness of the part after grinding.

[0006] Preferably, the steering mechanism includes an air injection pipe, a box cover, fastening holes and a rectangular frame. The air injection pipe is arranged through one side of the control box body, one end of the air injection pipe is connected to the input end of the solenoid valve through a pipeline, the box cover is installed on one side of the control box body, a rectangular frame is arranged on one side of the box cover, and fastening holes are distributed in rectangular shapes on the surfaces of the box cover and the rectangular frame.

[0007] Preferably, the fastening holes formed through the outer side of the box cover are connected to the outer side of the rectangular frame.

[0008] Preferably, the telescopic mechanism includes a pneumatic proportional valve, an angle meter, a cylinder, a workpiece to be processed, a distance grating, a solenoid valve and a guide rail. A pneumatic proportional valve is arranged inside the control box, one side of the pneumatic proportional valve is connected to the cylinder input end, the output end of the cylinder is connected to the workpiece to be processed, the outside of the cylinder is connected to the distance grating, the input end of the pneumatic proportional valve is connected to the solenoid valve, and the guide rails are symmetrically arranged inside the control box.

[0009] Preferably, the control box is connected to the workpiece to be processed via a guide rail arranged inside.

[0010] Preferably, a square lead-out hole is formed through one side of the control box.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. Push the parts through the retractable cylinder, control the pushing force of the parts with constant force, keep the grinding power constant, and the swing angles of the parts are different. Use the angle meter to keep the angle constant and measure the sub-item force to meet the grinding and chamfering of the workpiece at different angles. It is controlled by constant pressure to avoid unevenness on the grinding panel of the parts, and to control the pushing force of the parts when they are ground at different angles.

[0013] 2. During the pushing process, one side of the workpiece is positioned by the guide rail set in the middle. When the workpiece is polished, the other side of the workpiece is positioned by the guide rail to avoid the displacement or tilt of the workpiece caused by the polishing force. The telescopic distance of the cylinder is controlled by the inclinometer and the pneumatic proportional valve to ensure the change of the lifting distance of the equipment due to the inflation volume, which is conducive to ensuring the accuracy of equipment control.

[0022] like Figures 1 to 5 As shown, the grinding force control mechanism includes a control box 1, and a steering mechanism 5 is arranged on the outer side of the control box 1. When the steering mechanism 5 positions the outer side of the control box 1, the position of the control box 1 is adjusted, the grinding angle and position of the grinding mechanism are adjusted, and the swing angle of the part is dynamically adjusted. The control box 1 is provided with a telescopic mechanism 7 inside, and the telescopic mechanism 7 pushes the part laterally and controls the grinding pressure of the part to avoid unevenness of the part after grinding.

[0023] In this embodiment, the steering mechanism 5 includes an air injection pipe 2, a box cover 3, fastening holes 4 and a rectangular frame 6. The air injection pipe 2 is arranged through one side of the control box 1, and one end of the air injection pipe 2 is connected to the input end of the solenoid valve 13 through a pipeline. The box cover 3 is installed on one side of the control box 1, and a rectangular frame 6 is arranged on one side of the box cover 3. The surfaces of the box cover 3 and the rectangular frame 6 are rectangularly distributed with fastening holes 4, which are connected to the robot arm through the fastening holes 4, and the rectangular frame 6 and the box cover 3 are locked.

[0024] In this embodiment, the fastening holes 4 formed on the outer side of the box cover 3 are connected to the outer side of the rectangular frame 6 , and one side of the control box 1 is positioned through the rectangular frame 6 to ensure the control flexibility of the control box 1 .

[0025] In this embodiment, the telescopic mechanism 7 includes a pneumatic proportional valve 8, an inclinometer 9, a cylinder 10, a workpiece to be processed 11, a distance grating 12, a solenoid valve 13 and a guide rail 14. The control box 1 is provided with a pneumatic proportional valve 8, one side of the pneumatic proportional valve 8 is connected to the input end of the cylinder 10, the output end of the cylinder 10 is connected to the workpiece to be processed 11, the outer side of the cylinder 10 is connected to the distance grating 12, the input end of the pneumatic proportional valve 8 is connected to the solenoid valve 13, and the guide rail 14 is symmetrically arranged inside the control box 1.

[0026] In this embodiment, the control box 1 is connected to the workpiece 11 through a guide rail 14 provided inside, and the workpiece is positioned by the guide rail 14 to ensure the stability of the workpiece during the grinding process.

[0027] In this embodiment, a lead-out square hole 15 is formed through one side of the control box 1 , and the grinding position and direction of the workpiece are adjusted through the lead-out square hole 15 .

[0028] This grinding force control mechanism includes the following work contents in practical application:

[0030] Step 2: The operator pushes the workpiece 11 to be processed on one side through the cylinder 10, so that the workpiece 11 moves outside the guide rail 14. While pushing the workpiece out, the operator uses the robot arm to adjust the angle and height of the control box 1, so that the workpiece and the grinder form different angles to meet the chamfering of the edge after grinding the surface of the workpiece. The inclinometer 9 detects the inclination angle of the control box 1, and uses the inclinometer 9 to keep a constant angle and measure the sub-item force;

[0031] Step 3: When the cylinder 10 pushes the workpiece 11 on one side laterally, and the workpiece 11 moves on the outside of the guide rail 14, the lead-out distance of the workpiece 11 is adjusted, and the position of the workpiece 11 on one side is checked through the distance grating 12, and converted into displayable numbers for observation by outsiders, thereby facilitating standardized control of the grinding force and distance of the same batch of workpieces;

[0033] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
