Description

Technical Field

[0001] This utility model belongs to the field of CNC punching machine technology, specifically relating to a platform support device for CNC punching machines. Background Technology

[0002] A CNC punch press, short for numerical control punch press, is an automated machine tool equipped with a program control system. This control system logically processes and decodes programs containing control codes or other symbolic instructions, thereby enabling the punch press to move and process parts. CNC punch presses require a support device for installation and fixation.

[0003] Currently, most platform support devices for CNC punch presses use fixed and movable clamping plates to hold the mounting table in place and fix the punch press body to the platform support device through clamping force. For example, a CNC punch press platform support device with quick locking and fixing is disclosed in Chinese Patent Publication No. CN210435120U. However, because the position of the movable clamping plate is adjusted by threads, and the fixed and movable clamping plates do not lock the movable clamping plate after clamping the mounting table, the movable clamping plate often shifts due to vibration, causing the punch press body on the platform support device to loosen. At the same time, the punch press body has a single orientation after installation. When facing different production line layouts and multi-angle processing requirements, it is not easy to adjust the orientation of the punch press body, which limits its application range and reduces the adaptability of the production site.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figures 1 to 13 As shown, a platform support device for a CNC punch press includes a support platform 1. A mounting platform 2 is fitted onto the upper surface of the support platform 1. A punch press body 3 is fixedly connected to the upper surface of the mounting platform 2. A fixing bracket 4 is fitted onto the surface of the mounting platform 2, and the bottom of the fixing bracket 4 is fixedly connected to the upper surface of the support platform 1. Movable brackets 5 are fitted onto both the upper surface of the support platform 1 and the surface of the mounting platform 2. A trapezoidal groove 6 is formed on the upper surface of the support platform 1. A trapezoidal slider 7 is fitted onto the inner wall of the trapezoidal groove 6. The upper surface of the trapezoidal slider 7 is fitted onto the bottom of the movable bracket 5. A first U-shaped plate 8 is fixedly connected to the upper surface of the support platform 1. The first U-shaped plate 8 has openings on both its left and right sides. A threaded cylinder 10 is fixedly connected to the inner wall of the first circular hole 9. A first bolt 11 is threadedly connected to the inner wall of the threaded cylinder 10. The left side of the first bolt 11 fits against the right side of the movable clamping platform 5. An annular groove 12 is formed on the surface of the first bolt 11. A second U-shaped plate 13 is fitted against the inner wall of the first U-shaped plate 8. A first rectangular hole 14 is formed on both the left and right sides of the first U-shaped plate 8. A second rectangular hole 15 is formed on both the left and right sides of the second U-shaped plate 13. A locking bracket 16 is fitted against the inner wall of the first rectangular hole 14, the inner wall of the second rectangular hole 15, and the inner wall of the annular groove 12. The bottom of the locking bracket 16 is fixedly connected to the inner wall of the second U-shaped plate 13.

[0034] The locking bracket 16 includes a hollow plate 161, a spring 162, and a rectangular block 163. The bottom of the hollow plate 161 is fixedly connected to the inner wall of the second U-shaped plate 13. The surface of the hollow plate 161 is in contact with the inner wall of the annular groove 12. The inner wall of the hollow plate 161 is fixedly connected to the surface of the spring 162. Both the left and right ends of the spring 162 are fixedly connected to the sides of the rectangular block 163. The inner walls of the first rectangular hole 14 and the second rectangular hole 15 are in contact with the surface of the rectangular block 163. Rectangular tubes 17 are fixedly connected to the left and right sides of the inner wall of the second U-shaped plate 13. The inner walls of the rectangular tubes 17 are in contact with the surface of the rectangular block 163.

[0035] It should be noted that when the fixed clamping platform 4 and the movable clamping platform 5 clamp the mounting platform 2, the punch press body 3 can be fixed on the support platform 1 through the cooperation of the fixed clamping platform 4, the movable clamping platform 5 and the mounting platform 2. When the movable clamping platform 5 releases the mounting platform 2, the punch press body 3 can be directly removed from the support platform 1. Through the cooperation of the trapezoidal groove 6 and the trapezoidal slider 7, the movable clamping platform 5 can only move left and right on the support platform 1.

[0036] When the user rotates the first bolt 11, the first bolt 11 can move to the left or right through the cooperation of the first bolt 11 and the threaded cylinder 10. When the first bolt 11 presses the movable clamping platform 5, the fixed clamping platform 4 and the movable clamping platform 5 clamp the mounting platform 2 through the first bolt 11. When the first bolt 11 separates from the movable clamping platform 5, the movable clamping platform 5 releases the mounting platform 2.

[0037] When the locking bracket 16 is inserted into the first U-shaped plate 8, the locking bracket 16 can be positioned by the cooperation of the second U-shaped plate 13 and the first U-shaped plate 8. When the rectangular block 163 is inserted into the second rectangular hole 15, the hollow plate 161 can be fixed in the annular groove 12 by the cooperation of the rectangular block 163 and the first rectangular hole 14. The first bolt 11 cannot rotate in the threaded cylinder 10 by the cooperation of the hollow plate 161 and the annular groove 12. When the user presses the rectangular block 163, the rectangular block 163 can be separated from the first rectangular hole 14 by the pressing force. At the same time, the rectangular cylinder 17 can prevent the rectangular block 163 from being misaligned with the second rectangular hole 15 due to excessive pressing when the user presses the rectangular block 163. When the platform support device vibrates, although the rectangular block 163 will jump left and right due to the vibration, the jumping amplitude of the rectangular block 163 is small, so that the rectangular block 163 will not be separated from the first rectangular hole 14 due to vibration.

[0038] like Figures 1 to 14 As shown, a rotating bracket 18 is fixedly connected to the bottom of the support platform 1, and a second ring 19 is fixedly connected to the upper surface of the rotating bracket 18. A threaded hole 20 is opened inside the second ring 19, and a second circular hole 21 is opened inside the support platform 1. A second bolt 22 is fitted to both the inner wall of the second circular hole 21 and the upper surface of the support platform 1. The surface of the second bolt 22 is threadedly connected to the inner wall of the threaded hole 20.

[0039] The rotating bracket 18 includes a base plate 181, a first ring 182, a bearing 183, a cylinder 184, and a support column 185. The bottom of the first ring 182 and the bottom of the second ring 19 are both fixedly connected to the upper surface of the base plate 181. The inner wall of the first ring 182 is fixedly connected to the outer ring of the bearing 183. The inner ring of the bearing 183 is fixedly connected to the surface of the cylinder 184. The top of the cylinder 184 is fixedly connected to the bottom of the support platform 1. The axis of the second ring 19 coincides with the axis of the first ring 182. The bottom of the support column 185 is fixedly connected to the upper surface of the base plate 181, and the upper surface of the support column 185 is in contact with the bottom of the support platform 1.

[0040] It should be noted that when the second bolt 22 is screwed into the threaded hole 20, the support platform 1 cannot rotate due to the cooperation between the second bolt 22 and the threaded hole 20. When the second bolt 22 is screwed out of the threaded hole 20, the support platform 1 can rotate around the cylinder 184 by rotating the bracket 18. At the same time, the second ring 19 is provided with multiple threaded holes 20. By screwing the second bolt 22 into the threaded holes 20 at different positions, the orientation of the punch press body 3 can be changed. Thus, the platform support device can adjust the orientation of the punch press body 3 according to different usage requirements, and support the support platform 1 through the support column 185.

[0041] The working principle of this utility model is as follows: First, by pressing the rectangular block 163, the rectangular block 163 is separated from the first rectangular hole 14. Then, by pushing the rectangular block 163, the second U-shaped plate 13 is moved from the first U-shaped plate 8. Next, by rotating the first bolt 11, the first bolt 11 is unscrewed from the threaded cylinder 10. Finally, by moving the movable locking platform 5 to the right, the distance between the movable locking platform 5 and the fixed locking platform 4 reaches its maximum value.

[0042] Then, the punch press body 3 with mounting platform 2 is placed on support platform 1, and the fixed clamping platform 4 is in contact with the left side of mounting platform 2, and the movable clamping platform 5 is in contact with the right side of mounting platform 2. Then, the first bolt 11 is screwed into the threaded cylinder 10, and the first bolt 11 is pressed against the movable clamping platform 5. At this time, the fixed clamping platform 4 and the movable clamping platform 5 clamp the mounting platform 2, and the punch press body 3 can be fixed on support platform 1 through the cooperation of the fixed clamping platform 4, the movable clamping platform 5 and the mounting platform 2.

[0043] Then, the first U-shaped plate 8 is inserted into the second U-shaped plate 13, and the rectangular block 163 is inserted into the first rectangular hole 14. At this time, the elastic force of the spring 162 makes it impossible for the rectangular block 163 to separate from the first rectangular hole 14. Then, through the cooperation of the rectangular block 163 and the first rectangular hole 14, the hollow plate 161 is fixed in the annular groove 12. Through the cooperation of the hollow plate 161 and the annular groove 12, the first bolt 11 cannot rotate in the threaded cylinder 10. At this time, the mounting platform 2, the fixed clamping platform 4 and the movable clamping platform 5 are not easy to loosen.

[0044] When it is necessary to adjust the orientation of the punch press body 3, first, by rotating the second bolt 22, the second bolt 22 is separated from the threaded hole 20. Then, by rotating the support table 1, the support table 1 rotates around the cylinder 184. By screwing the second bolt 22 into the threaded hole 20 at the designated position, the orientation of the punch press body 3 can be changed.

[0045] When it is necessary to remove the main body 3 of the punch press from the platform device of the CNC punch press, first press the rectangular block 163 to separate the rectangular block 163 from the first rectangular hole 14, and push the rectangular block 163 to move the second U-shaped plate 13 from the first U-shaped plate 8. Then, turn the first bolt 11 to unscrew it from the threaded cylinder 10, and move the movable chuck 5 to the right to release the mounting table 2. At this time, the main body 3 of the punch press can be removed from the support table 1.

[0046] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
