Description
Technical Field
[0001] The utility model relates to the technical field of automatic loading and unloading devices, in particular to a built-in pneumatically controlled automatic loading and unloading device for a five-axis CNC tool grinder. Background Art
[0002] The automatic loading and unloading device is an automatic loading and unloading robot arm whose stroke can be controlled by a program. It can facilitate the loading and unloading of workpieces inside the machine tool and is an important auxiliary tool for realizing automated processing. In particular, in five-axis CNC grinders, in order to realize the automated processing of small bars, it is usually necessary to use an automatic loading and unloading device to remove the small bars from the material plate and install them on the processing table. The five-axis CNC grinder can quickly and automatically grind small bars without the need for staff to manually fix the bars. The automatic loading and unloading device is mainly composed of power components such as rotating cylinders, telescopic cylinders and finger clamping cylinders. Pneumatic control is used to enable the automatic loading and unloading device to clamp and move the bars.
[0003] When the existing five-axis CNC tool grinder has a built-in pneumatically controlled automatic loading and unloading device in use, a cylinder is used as a power source to drive two finger-shaped clamping mechanisms to clamp the bar stock. During the bar clamping process, multiple discharged bar stocks will block the finger clamping mechanism, and the finger clamping mechanism needs to be moved in front of the bar stock. After the finger clamping mechanism opens, it is moved close to the bar stock again so that the bar stock is located in the middle of the finger clamping mechanism. At this time, the handheld clamping mechanism cooperates with the cylinder to clamp the bar stock. This process is relatively complicated, which increases the movement stroke of the robot arm during the process of clamping the bar stock by the automatic loading and unloading device, thereby slowing down the processing efficiency of the bar stock in the five-axis CNC grinder, and the surface of the bar stock is easily bumped and scratched during the clamping process, which reduces the surface accuracy of the bar stock, and to a certain extent affects the overall use efficiency and bar clamping safety of the built-in pneumatically controlled automatic loading and unloading device of the five-axis CNC tool grinder.

[0028] The working principle of the present invention is as follows: when in use, first install the mounting seat 1 in conjunction with the mounting plate 6 and the mounting through hole 7 on the five-axis CNC grinder, and connect the rotating cylinder 3 and the telescopic cylinder 9 to the air source on the five-axis CNC grinder, and at the same time electrically connect the external power supply and the controller to the air pump 510. When it is necessary to take the bar material, first use the telescopic cylinder 9 to push the connecting frame 2 to change the elevation angle until the material taking barrel 502 is in a vertical state. At this time, the X-axis moving mechanism on the five-axis CNC grinder is used to drive the support arm 4 and the material taking barrel 502 to move left and right until the material taking barrel 502 is directly above the bar material. Then, the up and down movement of the Z-axis on the five-axis CNC grinder is coordinated with the mounting seat 1, the connecting frame 2, the rotating cylinder 3 and the support arm 4 to drive the material taking barrel 502 to The rod is then moved downward until it is inserted into the material taking barrel 502. When a slight deviation occurs during the insertion of the rod into the material taking barrel 502, the second plastic guide seat 513 itself has a conical surface and a lower hardness than the rod, which can smoothly guide the rod into the material taking barrel 502 and contact the first plastic guide seat 506 without scratching the surface of the rod. At this time, the conical surface of the first plastic guide seat 506 cooperates with the buffer spring 503 to keep the rod in the center position inside the material taking barrel 502, thereby improving the accuracy of the rod taking. Then, the suction provided by the air pump 510 is used to filter the outside air through the filter barrel 512 and then send it into the rubber airbag 507 from the air guide pipe 511, so that the rubber airbag 507 expands and cooperates with the anti-slip pad 5 08 and the friction force provided by the anti-slip groove 509 initially clamp the bar from the center position and further locate the position of the bar. Finally, the suction force generated by the electromagnet 504 after being energized can be used to adsorb and fix the position of the bar inside the material-retrieving barrel 502 from the top of the bar, so that the built-in pneumatically controlled automatic loading and unloading device of the five-axis CNC tool grinder only needs to move downward to quickly complete the bar-retrieving work, without having to move to the front of the bar and then approach the bar for clamping, reducing the one-step stroke of the built-in pneumatically controlled automatic loading and unloading device of the five-axis CNC tool grinder to clamp the bar, thereby indirectly improving the subsequent bar processing efficiency, and at the same time effectively reducing the bumps and scratches on the bar, ensuring the surface accuracy of the bar during loading and unloading, and improving to a certain extent. The overall utilization efficiency and bar clamping safety of the built-in pneumatically controlled automatic loading and unloading device of the five-axis CNC tool grinder are improved. When the bar needs to be unloaded, the Z-axis of the five-axis CNC grinder is first used to drive the bar to move upward and away from the material tray, and then the supporting arm 4 and the material barrel 502 are driven to rotate 180 degrees by the rotating cylinder 3 to rotate the bar from a vertical state to a horizontal state. Finally, the Z-axis and X-axis of the five-axis CNC grinder are used to drive the bar to move downward and then to the left and send it into the bar processing fixture. At this time, the fixture clamps the bar, the electromagnet 504 disconnects the power supply, the air pump 510 stops working, and the gas is discharged from the air pump 510 outward through the contraction of the rubber airbag 507's own elastic force, thereby releasing the clamping of the bar and completing the unloading of the bar.
