Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding technology, specifically to a grinding machine for machining mechanical parts. Background Technology
[0002] A grinding machine is a machine tool that uses abrasives to grind the surface of a workpiece. It mainly uses a high-speed rotating grinding wheel or other abrasives to remove excess material from the surface of the workpiece, thereby achieving high-precision machining. Grinding machines play an important role in the machinery manufacturing and metal processing industries, and can process various metal and non-metal workpieces. They are suitable for the manufacture of precision parts and the grinding of tools.
[0003] Most existing grinding machines use grinding wheels to grind parts. After the part is fixed on the machine tool slot plate, the grinding wheel is placed on the surface of the part. Then, the machine tool is manually cranked to move the machine tool slot plate left and right and back and forth, causing the machine tool slot plate to move the part back and forth under the grinding wheel, so that the part is ground by the grinding wheel. In this process, the operator needs to constantly adjust the part, which makes it impossible to achieve automatic grinding. To address this, we propose a grinding machine for machining mechanical parts. Utility Model Content

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] Reference Figures 1 to 5 This utility model provides a technical solution: a mechanical component processing grinding machine, including a multi-axis gantry robot 2, which is a three-axis gantry robot, a four-axis gantry robot, or a five-axis gantry robot. The multi-axis gantry robot 2 is set on the top of a platform 16, and cabinets 15 are respectively provided on both sides of the bottom of the platform 16. A controller is provided in the cabinet 15, which is a PLC logic controller or a host, etc. The controller is connected to the multi-axis gantry robot 2.
[0022] The top surface of the platform 16 is provided with a receiving opening 7 in the middle. One end of the receiving opening 7 is connected to one side of the platform 16. The receiving opening 7 is located in the working area of the multi-axis gantry robot 2. The bottom of the platform 16 is provided with a strip frame 24. The strip frame 24 is located below the receiving opening 7 and one end of it extends to the outside of the receiving opening 7. A support leg 12 is provided at the end of the strip frame 24 away from the receiving opening 7. The support leg 12 is flush with the bottom of the cabinet 15.
[0023] The top two sides of the strip-shaped frame 24 are respectively provided with first support guide rails 10. A mounting plate 14 is parallel to the top of the first support guide rails 10. The bottom of the mounting plate 14 is slidably connected to the first support guide rails 10 via a first slider 13. A machine tool slot plate 9 is mounted on the top of the mounting plate 14, and a clamp is provided on the machine tool slot plate 9. It should be noted that the machine tool slot plate 9 is one of the most common spare parts for machine tools, and the structure of the machine tool slot plate 9 here remains unchanged and unmodified. In use, the part to be polished is placed on the machine tool slot plate 9 and then fixed using the clamp.
[0024] A transmission screw 8, parallel to the first support guide rail 10, is threadedly connected to the bottom of the mounting plate 14. Both ends of the transmission screw 8 are rotatably connected to the strip frame 24. Figure 1 and Figure 2 As shown, the strip frame 24 protruding outside the platform 16 is longer than the machine tool slot plate 9 and the mounting plate 14. This allows the machine tool slot plate 9 to be completely driven out of the receiving port 7, which is convenient for loading and unloading. When the part is fixed, the transmission screw 8 can be rotated to drive the machine tool slot plate 9 into the receiving port 7. At this time, the part is also located in the working area of the multi-axis gantry robot 2.
[0025] There are two ways to drive the transmission screw 8 to rotate. The first way is to connect one end of the transmission screw 8 to the drive motor, which is located at the end of the strip frame 24. The drive motor can drive the transmission screw 8 to rotate. The second way is to connect one end of the transmission screw 8 to the rotating handle 11, so that the transmission screw 8 can be rotated by hand.
[0026] Furthermore, a mounting frame 1 is installed on the free end of the multi-axis gantry robot 2. Taking a three-axis gantry robot as an example, the mounting frame 1 is set at the bottom of the Z-axis of the multi-axis gantry robot 2, so that the mounting frame 1 moves with the movement of the multi-axis gantry robot 2. The receiving port 7 is located below the mounting frame 1.
[0027] like Figure 1 and picture Figure 3 As shown, a support wheel 5 is rotatably mounted at the bottom of the mounting frame 1. The edge of the support wheel 5 must extend beyond the bottom of the mounting frame 1. A drive wheel 3 is rotatably mounted on one side of the top of the mounting frame 1. The drive wheel 3 is connected to a drive motor 17 mounted on the mounting frame 1. The drive motor 17 is connected to a controller. One side of the mounting frame 1 is also connected to an adjusting wheel 6 through a tensioning adjustment mechanism. The adjusting wheel 6, the drive wheel 3, and the support wheel 5 are connected by a grinding belt 4.
[0028] The adjusting wheel 6, drive wheel 3, and support wheel 5 are arranged in a triangular pattern, specifically, the adjusting wheel 6 and drive wheel 3 are positioned on both sides of the mounting frame 1. Figure 3 As shown, the drive wheel 3 is positioned slightly above the adjusting wheel 6, ensuring that the angle of wrap between the grinding belt 4 and the drive wheel 3 is at least 90°. When the drive motor 17 rotates, it can stably drive the grinding belt 4 to rotate. Since the support wheel 5 is located outside the bottom of the mounting frame 1, when the multi-axis gantry robot 2 lowers the mounting frame 1, the support wheel 5 first contacts the surface of the part, allowing the rotating grinding belt 4 to travel along the surface of the part according to the set path, thereby grinding the surface of the part.
[0029] The tension adjustment mechanism is essential. It not only tightens the grinding belt 4, but also facilitates replacement of the grinding belt 4 when the tension is loosened. Figure 5 and Figure 4As shown, the tension adjustment mechanism includes a support arm 21. One end of the support arm 21 is connected to one side of the mounting frame 1. At least one second support guide rail 20 is installed on the side of the support arm 21 near the drive wheel 3. A second slider 19 is slidably provided on the second support guide rail 20. A support 18 is installed on the side of the second slider 19. One end of the adjustment wheel 6 is rotatably installed in the support 18, so that the adjustment wheel 6 can slide along the second support guide rail 20. When the adjustment wheel 6 slides towards the mounting frame 1, the grinding belt 4 can be disassembled. When the adjustment wheel 6 slides away from the mounting frame 1, the grinding belt 4 is tightened.
[0030] One side of the support arm 21 is also provided with an adjusting screw 23 parallel to the second support guide rail 20. The two ends of the adjusting screw 23 are rotatably installed in the fixed seat 22. The fixed seat 22 is fixed to the support arm 21. A matching nut is threaded on the adjusting screw 23. The nut is fixed to the second slider 19. The left and right movement of the adjusting wheel 6 can be achieved by rotating the adjusting screw 23. In order to facilitate the rotation of the adjusting screw 23, a square prism head or a hexagonal head is provided at one end of the adjusting screw 23, and at least one fastening nut is threaded on the adjusting screw 23.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
