Description

Technical Field

[0001] The invention relates to the technical field of CNC lathes, and in particular to a vertical CNC lathe which is convenient for loading and unloading materials. Background Art

[0002] A CNC lathe is a high-precision, high-efficiency automated machine tool. CNC lathes include horizontal CNC lathes and vertical CNC lathes. The horizontal CNC lathe has a horizontally arranged spindle and is the most common type of CNC lathe, suitable for processing various shaft and disc parts. The vertical CNC lathe has a vertically arranged spindle and its worktable is horizontally arranged, and is mainly used for processing large disc parts with large diameter and short length.

[0003] For a vertical CNC lathe, when processing a disc-type workpiece, it is necessary to clamp the bottom of the workpiece through the chuck on its worktable, and then the feed system moves the tool to the upper area of ​​the workpiece and performs turning on the upper area of ​​the workpiece. After the upper area of ​​the workpiece is processed, it is necessary to flip the workpiece and process the remaining part of the workpiece.

[0004] A Chinese patent with authorization announcement number CN114474114B discloses a robot for automatically flipping workpieces on a production line. The robot includes a robot arm, a flange rod, and the robot arm is preset on one side of the production line. The flange rod is fixed to the output end of the robot arm. The flipping assembly includes a connecting plate, a first clamping assembly and a second clamping assembly. The connecting plate is fixed to the end of the flange rod away from the robot arm. The flipping assembly includes at least three groups of first clamping assemblies and three groups of second clamping assemblies. The first clamping assembly and the second clamping assembly are symmetrically and rotatably arranged on the connecting plate.

[0005] The above-mentioned manipulator clamps the workpiece through the first clamping assembly or the second clamping assembly, and then drives the first clamping assembly or the second clamping assembly to rotate through the flipping motor, thereby realizing the flipping of the workpiece. However, during the flipping process, the first clamping assembly and the second clamping assembly in the above-mentioned manipulator rotate around the flipping axis through the mounting plate, thereby driving the clamping plate to rotate, and then driving the workpiece clamped by the clamping plate to rotate. Since the mounting plate can only rotate around the axis of the flipping axis, the workpiece can only be flipped in the horizontal plane. When the workpiece needs to be flipped up and down, the above-mentioned manipulator cannot flip the workpiece up and down. Summary of the invention

By rotating the seat 102 and each rotating arm, the tail end of the fourth rotating arm 106 can be freely moved in space.

[0038] like Figures 2 to 6 As shown, the flip assembly includes a first mounting plate 2, a second mounting plate 3, a first rotating disk 4, a second rotating disk 5 and a clamping mechanism 8. The first mounting plate 2 is fixedly connected to the tail end of the fourth rotating arm 106. A rotating hole is provided on the side wall of the first mounting plate 2. A rotating shaft is provided on the side wall of the second mounting plate 3. The rotating shaft extends into the rotating hole and rotates with the rotating hole.

The first driving member 6 can drive the second mounting plate 3 to rotate around the rotating shaft relative to the first mounting plate 2. The first rotating disk 4 is rotatably matched at the center of the first mounting plate 2, and the second rotating disk 5 is rotatably matched at the center of the second mounting plate 3. A driving unit 7 is provided between the fourth rotating arm 106 and the first mounting plate 2 and the second mounting plate 3.

The third driving member is fixedly arranged in the fourth rotating arm 106. The third driving member is a motor. One end of the first driving member 6 is fixedly connected to the output end of the third driving member, and the other end thereof is fixedly provided with a first gear 74. The second driving rod 72 is rotatably matched in the first mounting plate 2. One end of the second driving rod 72 is fixedly provided with a second gear 75, and the other end thereof is fixedly provided with a third gear 76. The third gear 76 is meshed with the first gear 74. A first tooth groove 41 is provided at the bottom of the side wall of the first rotating disk 4. The first tooth groove 41 is meshed with the third gear 76. The third rotating rod is rotatably matched in the second mounting plate 3. A fourth gear 77 is fixedly provided at one end of the third driving rod 73, and the fourth gear 77 meshes with the first gear 74. A fifth gear 78 is fixedly provided at the other end of the third driving rod 73. A second tooth groove 51 is provided on the top of the side wall of the second rotating disk 5, and the second tooth groove 51 meshes with the fifth gear 78. The first gear 74, the second gear 75, the third gear 76, the fourth gear 77 and the fifth gear 78 are all helical gears. Since the second driving rod 72 and the third driving rod 73 are respectively located on both sides of the first driving rod 71, when the first driving rod 71 rotates, the rotation directions of the second driving rod 72 and the third driving rod 73 are opposite, the first tooth groove 41 is a helical tooth groove, and the first tooth groove 41 meshes with the bottom of the third gear 76, the second tooth groove 51 is a helical tooth groove, and the second tooth groove 51 meshes with the top of the fifth gear 78, so that the rotation directions of the first rotating disk 4 and the second rotating disk 5 are the same, and when the driving unit 7 drives the two to rotate, the two can rotate synchronously.

[0039] like Figure 3 , Figures 7 to 9As shown, the first rotating disk 4 and the second rotating disk 5 are both provided with a clamping mechanism 8, the clamping mechanism 8 includes a clamping rod 81, a fixing seat 82 and a second driving member 83, the first rotating disk 4 is provided with four slide grooves 85, the four slide grooves 85 are evenly distributed along the circumference of the first rotating disk 4, each slide groove 85 extends along the radial direction of the first rotating disk 4, the inner ends of the four slide grooves 85 are connected to each other, thereby forming a cross structure, each slide groove 85 is matched with a clamping rod 81, the top end of the clamping rod 81 A limit block 9 is fixedly arranged, and the limit block 9 is a rectangular block. The width of the limit block 9 is the same as the width of the slide groove 85. The side wall of the limit block 9 fits with the side wall of the slide groove 85. An outer edge 91 is fixedly arranged on the side wall of the limit block 9. A limit groove 851 is arranged on the side wall of the slide groove 85. The outer edge 91 can extend into the limit groove 851 and move along the limit groove 851. The upper surface and the lower surface of the outer edge 91 both stop against the groove wall of the limit groove 851, thereby preventing the clamping rod 81 from moving up and down. A gantry is fixedly arranged on the first rotating disk 4. The second driving member 83 is a hydraulic cylinder, which is fixedly arranged on the gantry. The output end of the second driving member 83 extends downward. The fixed seat 82 is fixedly arranged on the output end of the second driving member 83. Each limit block 9 is hinged with the fixed seat 82 through a connecting rod 84. When the second driving member 83 drives the fixed seat 82 to move upward, the fixed seat 82 pulls the clamping rod 81 to move inward along the slide groove 85 through the connecting rod 84. When the second driving member 83 drives the fixed seat 82 to move downward, the fixed seat 82 pushes the clamping rod 81 to move outward along the slide groove 85 through the connecting rod 84. The inner and outer side walls of the clamping rod 81 are both provided with anti-skid pads 10, which are made of flexible rubber. The anti-skid pads 10 are provided with a plurality of anti-skid protrusions spaced apart along the axial direction of the clamping rod 81. The anti-skid pads 10 are used to increase the friction between the clamping rod 81 and the workpiece 3000, thereby improving the clamping ability of the clamping rod 81. The structure of the second rotating disk 5 is the same as that of the first rotating disk 4 .

[0040] like Figure 4 , Figure 6 and Figure 7 As shown, a plurality of cleaning brushes 11 are fixedly provided at the bottom ends of the first rotating disk 4 and the second rotating disk 5. The plurality of cleaning brushes 11 are evenly spaced along the circumference of the first rotating disk 4 or the second rotating disk 5. Each cleaning brush 11 extends radially along the first rotating disk 4 or the second rotating disk 5. When the clamping mechanism 8 clamps the workpiece 3000, the cleaning brush 11 is located between the workpiece 3000 and the first rotating disk 4 or the second rotating disk 5.

[0041] The implementation principle of the vertical CNC lathe that is convenient for loading and unloading in the embodiment of the present invention is as follows: the robot arm moves the first mounting plate 2 to the top of the workpiece 3000, and makes the first rotating disk 4 coaxially distributed with the workpiece 3000, and then the robot arm drives the first mounting plate 2 to move downward, so that the cleaning brush 11 at the bottom of the first rotating disk 4 stops at the top of the workpiece 3000, the third driving member is started, and drives the second driving rod 72 to rotate through the engagement of the first gear 74 and the second gear 75, the second driving rod 72 drives the first rotating disk 4 to rotate through the third gear 76, the cleaning brush 11 rotates synchronously with the first rotating disk 4, and cleans the workpiece 3000, removes oil and debris attached to the upper area of ​​the workpiece 3000, and cleans the workpiece 3000. After cleaning is completed, the third driving member stops, and the second driving member 83 drives the fixed seat 82 to move upward, and the fixed seat 82 pulls the clamping rod 81 inward through the connecting rod 84, so that the clamping rod 81 clamps the outer wall of the workpiece 3000. In some other embodiments, the outer wall of the workpiece 3000 is difficult to clamp, and the second driving member 83 can drive the fixed seat 82 to move upward to the limit, so that the clamping rod 81 is retracted to the limit, and the first mounting plate 2 moves downward and the clamping rod 81 extends into the inner hole of the workpiece 3000. After cleaning is completed, the second driving member 83 drives the fixed seat 82 to move downward until the clamping rod 81 stops against the inner hole wall of the workpiece 3000, thereby clamping the workpiece 3000.

[0042] After clamping is completed, the robot arm moves the first mounting plate 2 to the top of the workbench and slowly descends until the workpiece 3000 falls on the chuck on the workbench. The chuck automatically locks the workpiece 3000, and the second driving member 83 drives the clamping rod 81 to disengage from the workpiece 3000 and move it out of the frame, and then the turning operation is performed.

[0043] If there is no need to perform turning processing on the lower area of ​​the workpiece 3000, during the processing, the loading and unloading device 2000 uses the first mounting plate 2 to clamp a workpiece 3000 to be processed again. After the turning processing is completed, the feeding mechanism removes the tool, and the robot arm moves the second mounting plate 3 to the top of the processed workpiece 3000, and then slowly descends, so that the cleaning pad at the bottom of the second mounting plate 3 contacts the processed workpiece 3000, and the driving unit 7 drives the second mounting plate 3 to rotate. When the second mounting plate 3 rotates, the cleaning brush 11 can clean the processed workpiece 3 000, then stops rotating the second rotating disk 5, the clamping mechanism 8 clamps the processed workpiece 3000, the chuck is released, the robotic arm drives the first mounting portion and the second mounting plate 3 to move upward, the third robotic arm rotates, so that the first mounting plate 2 exchanges positions with the second mounting plate 3, and then places the workpiece 3000 to be processed under the first mounting plate 2 on the workbench, then the robotic arm moves the first mounting plate 2 and the second mounting plate 3 out of the frame, and places the processed workpiece 3000 under the second mounting plate 3 in the unloading area, completing automatic loading and unloading.

[0044] If turning processing is required for the lower area of ​​the workpiece 3000, after the processing of the upper area of ​​the workpiece 3000 is completed, the feed mechanism removes the tool, and the robotic arm moves the first mounting plate 2 to the top of the workpiece 3000, and then the first mounting plate 2 descends, and the cleaning brush 11 at the bottom of the first mounting plate 2 contacts the workpiece 3000, and the driving unit 7 drives the first mounting plate 2 to rotate, and the cleaning brush 11 can remove the debris on the end face of the workpiece 3000, and then the clamping mechanism 8 on the first rotating disk 4 clamps the workpiece 3000, and the workpiece 3000 is moved out of the frame body by the robotic arm, and then the first driving member 6 drives the second mounting plate 3 to rotate around the rotating axis until the second mounting plate 3 rotates to the bottom of the workpiece 3000, as shown in the specific example. Fig.10 As shown, the clamping mechanism 8 on the second rotating disk 5 clamps the workpiece 3000, the clamping mechanism 8 on the first rotating disk 4 releases the workpiece 3000, and the first driving member 6 drives the rotating shaft to rotate in the opposite direction, thereby resetting the second mounting plate 3. At this time, the workpiece 3000 flips up and down 180 degrees, and then the robotic arm moves the second mounting plate 3 to the top of the workbench and slowly descends until the workpiece 3000 is placed on the workbench. At this time, the chuck clamps the workpiece 3000, and the clamping mechanism 8 on the second rotating disk 5 releases the workpiece 3000. The robotic arm moves the second mounting plate 3 out of the workbench, and then performs turning to process the remaining part of the workpiece 3000.
