Description

Technical Field

[0001] This utility model relates to the field of CNC spinning machine technology, specifically a clamping device for a CNC spinning machine. Background Technology

[0002] Spinning is a new chipless forming process for metal products, with high raw material utilization. The successful application of spinning technology and spinning machines has promoted the development of technologies such as aviation, rockets, missiles, and artificial satellites. In conventional weaponry, chemical industry, metallurgy, machinery manufacturing, electronics, light industry, and civilian sectors, CNC spinning machines have become the main equipment for metal processing products.

[0003] According to a clamping device for a CNC spinning machine (publication number: CN220942886U), the aforementioned application uses a knob to rotate a threaded rod, which in turn moves a threaded block up and down along the circumferential side of the threaded rod, thereby moving the sliding box and the clamping block up and down. The structure is simple and practical, and the height of the fixing component can be adjusted according to the length of the metal workpiece, avoiding the impact of the height of the fixing component on the processing of the metal workpiece, and bringing convenience to the operator.

[0004] However, in actual use, although the height of the fixed components can be easily adjusted, the rigid clamping of the mold by the clamping plates can cause the mold to slip under high-speed rotation, resulting in poor spinning effect. In view of this, we propose a clamping device for a CNC spinning machine. Utility Model Content

[0005] The purpose of this invention is to provide a clamping device for a CNC spinning machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for a CNC spinning machine, comprising a frame, a lifting assembly one disposed on the outer wall of the frame, a pressing rotation assembly disposed on the outer wall of the lifting assembly one, a lifting assembly two disposed on the outer wall of the frame, a rotation extension assembly disposed on the outer wall of the lifting assembly two, a clamping assembly disposed on the outer wall of the rotation extension assembly, the clamping assembly comprising a mounting plate, the mounting plate being fixedly connected to the outer wall of the rotation extension assembly, a bidirectional threaded rod being rotatably mounted on the inner wall of the mounting plate, a threaded slider being threadedly connected to the outer wall of the bidirectional threaded rod, a clamping plate being fixedly connected to the outer wall of the threaded slider, a fixing plate being fixedly connected to the inner wall of the clamping plate, an elastic telescopic post being fixedly connected to the inner wall of the clamping plate, and a transmission plate being fixedly connected to the outer wall of the elastic telescopic post;

[0007] A pressing inclined block is fixedly connected to the end of a transmission plate. A mounting base is fixedly connected to the inner wall of the clamping plate. A spring is fixedly connected to the outer wall of the mounting base. A movable sleeve is fixedly connected to the end of the spring. A pressure-bearing inclined block is fixedly connected to the end of the movable sleeve. A rubber plate is fixedly connected to the outer wall of the movable sleeve. A convex rubber block is fixedly connected to the outer wall of the rubber plate.

[0008] Preferably, the number of elastic expansion piles is several, and the several elastic expansion piles are arranged on both sides with the center plane of the clamp as a mirror image.

[0009] Preferably, the centerline of the extrusion block and the centerline of the pressure block are on the same straight line, and the outer wall of the extrusion block is adapted to the outer wall of the pressure block, so that the extrusion block can smoothly extrude the pressure block to make it displaced.

[0010] Preferably, the outer wall of the movable sleeve is slidably connected to the outer wall of the mounting base, so that the movable sleeve can move smoothly.

[0011] Preferably, the outer wall of the fixing plate is provided with a stabilizing component, the stabilizing component includes a fixed friction strip, the fixed friction strip is fixedly connected to the outer wall of the fixing plate, and the outer wall of the rubber plate is fixedly connected with a movable friction strip.

[0012] Preferably, the number of fixed friction strips is several, and the several fixed friction strips are arranged in a linear array on the outer wall of the fixed plate.

[0013] Compared with the prior art, this utility model provides a clamping device for a CNC spinning machine, which has the following advantages:

[0014] 1. The clamping device of this CNC spinning machine allows the mold to be placed on the clamping plate. The double-threaded rod can be rotated to cause the threaded slider to move the clamping plate, thereby clamping the mold. As the clamping plate gradually fixes the mold, the mold will press the elastic telescopic pile in the opposite direction. When the elastic telescopic pile contracts, it will drive the transmission plate to move, which in turn allows the extrusion wedge to smoothly press the pressure wedge to move. Finally, when the rubber plate contacts the outer wall of the mold, it can be additionally clamped towards the center. Furthermore, the convex rubber block can further improve the clamping effect and prevent the mold from slipping under high-speed rotation.

[0015] 2. The clamping device of the CNC spinning machine, when the extrusion slant block can smoothly extrude the pressure slant block for displacement, and finally when the rubber plate contacts the outer wall of the mold, it can be clamped towards the center, the fixed friction strip under the rubber plate will rub against the moving friction strip on the clamping plate, thereby increasing the contact area, further improving the stability, and ultimately increasing the overall practicality.

[0024] like Figures 1-7As shown, this utility model provides a technical solution: a clamping device for a CNC spinning machine, including a frame 1, a lifting assembly 2 on the outer wall of the frame 1, a pressing and rotating assembly 3 on the outer wall of the lifting assembly 2, the pressing and rotating assembly 3 being capable of performing conventional pressing and rotating operations to cooperate with the use of a mold, a second lifting assembly 4 on the outer wall of the frame 1, a rotating and extending assembly 5 on the outer wall of the second lifting assembly 4, the rotating and extending assembly 5 being capable of conventional rotating and extending operations, and a clamping assembly on the outer wall of the rotating and extending assembly 5. Component 6, the clamping assembly 6 includes a mounting plate 601, which is fixedly connected to the outer wall of the rotary extension assembly 5. A bidirectional threaded rod 602 is rotatably mounted on the inner wall of the mounting plate 601. A threaded slider 603 is threadedly connected to the outer wall of the bidirectional threaded rod 602. A clamping plate 604 is fixedly connected to the outer wall of the threaded slider 603. A fixing plate 605 is fixedly connected to the inner wall of the clamping plate 604. An elastic telescopic post 606 is fixedly connected to the inner wall of the clamping plate 604. A transmission plate 607 is fixedly connected to the outer wall of the elastic telescopic post 606.

[0025] Furthermore, the compression wedge 608 is fixedly connected to the end of the transmission plate 607, the inner wall of the clamping plate 604 is fixedly connected to the mounting base 609, the outer wall of the mounting base 609 is fixedly connected to the spring 610, the end of the spring 610 is fixedly connected to the movable sleeve 611, the end of the movable sleeve 611 is fixedly connected to the pressure-bearing wedge 612, the outer wall of the movable sleeve 611 is fixedly connected to the rubber plate 613, and the outer wall of the rubber plate 613 is fixedly connected to the protruding rubber block 614.

[0026] In the embodiments of this utility model, the number of elastic expansion piles 606 is several, and the several elastic expansion piles 606 are mirrored on both sides with the center plane of the clamping plate 604. The center line of the pressing inclined block 608 and the center line of the pressure-receiving inclined block 612 are on the same straight line, and the outer wall of the pressing inclined block 608 is adapted to the outer wall of the pressure-receiving inclined block 612, so that the pressing inclined block 608 can smoothly press the pressure-receiving inclined block 612 to move. The outer wall of the moving sleeve 611 is slidably connected to the outer wall of the mounting base 609, so that the moving sleeve 611 can move smoothly.

[0027] Furthermore, the outer wall of the fixed plate 605 is provided with a stabilizing component 7, which includes a fixed friction strip 701. The fixed friction strip 701 is fixedly connected to the outer wall of the fixed plate 605. The outer wall of the rubber plate 613 is fixedly connected with a movable friction strip 702.

Then, the mold is placed on the clamping plate 604, and the bidirectional threaded rod 602 is rotated to cause the threaded slider 603 to move the clamping plate 604, thereby clamping the mold. As the clamping plate 604 gradually fixes the mold, the mold will reverse the pressure of the elastic telescopic pile 606. When the elastic telescopic pile 606 contracts, it will drive the transmission plate 607 to move, thereby allowing the extrusion inclined block 608 to smoothly extrude the pressure inclined block 612 to move. Finally, when the rubber plate 613 contacts the outer wall of the mold, it can be additionally clamped towards the center. The clamping effect is further improved by the convex rubber block 614. Then, the right side of the metal workpiece is pressed tightly against the left side of the extrusion rotating assembly 3, and then the rotating extension assembly 5 is extended, thereby pressing the mold and the metal workpiece tightly together, and then the spinning operation can be performed.

[0029] When the extrusion slant 608 can smoothly extrude the pressure slant 612 to make displacement, and the rubber plate 613 can be clamped towards the center when it comes into contact with the outer wall of the mold, the fixed friction strip 701 under the rubber plate 613 will rub against each other with the moving friction strip 702 on the clamping plate 604, thereby increasing the contact area, further improving the stability, and ultimately increasing the overall practicality.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
