Description

Technical Field

[0001] This utility model belongs to the field of fixtures, specifically a rapid clamping and adaptive alignment device for CNC machining of four-station power fittings. Background Technology

[0002] In the field of CNC machining of power fittings, fixtures are the core components that ensure machining accuracy and efficiency. Currently, most power fitting machining fixtures used in the industry adopt a single-station or dual-station design, which can only process 1-2 workpieces at a time. Moreover, the clamping process relies on manual adjustment and positioning, which is cumbersome. Most fixtures rely on manual driving of clamping actions and are not combined with pneumatic or other automated driving methods, which cannot achieve rapid clamping and releasing. This further restricts the improvement of production efficiency, makes it difficult to match the pace of modern CNC machining production lines, and cannot meet the needs of mass production. This results in low overall machining efficiency. In addition, after the fittings are placed, they are prone to being non-parallel to the machining reference (such as the base plate), requiring repeated manual calibration. This not only increases operation time but also makes it easy for human error to cause the fittings to fail to meet the machining accuracy standards, affecting the stability of product quality. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a quick clamping and adaptive alignment device for CNC machining of four-station power fittings, which solves the problems mentioned in the background art.

[0023] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1-6 As shown, a rapid clamping and adaptive alignment device for CNC machining of four-station power fittings includes a fitting 4 and a base plate 1 for placing the fitting 4. The fitting 4 has arc-shaped ends, a cylindrical protrusion at the bottom, and a rectangular concave surface at the top. The surface of the base plate 1 has multiple cylindrical mounting grooves for fitting the cylindrical structure at the bottom of the fitting 4. Multiple sets of clamps are provided on the upper side of the base plate 1 to hold the fitting 4. An alignment device is provided on one side of the fitting 4 to push the fitting 4, keeping it parallel to the base plate 1, facilitating machining of the fitting 4 and ensuring machining accuracy. Figure 3 As shown, this embodiment can clamp four workpieces simultaneously. Through the alignment device, it can adaptively align, automatically lock the fixture, and enable rapid production, thus solving the problems of low efficiency and poor adaptability of the existing technology.

[0025] The alignment device includes a positioning plate 6 and a parallel rod 10 arranged parallel to each other. The positioning plate 6 and the base plate 1 are arranged parallel to each other and fixedly connected. The parallel rod 10 has protrusions on both sides of its end facing the fitting 4. The protrusions press against the end face of the fitting 4 to push it. The endpoints of the two protrusions are on the same plane, ensuring that the endpoints of the protrusions, the parallel rod 10, the positioning plate 6, and the base plate 1 remain parallel. A positioning pull rod 7 is fixedly connected to the middle of the end of the parallel rod 10 facing the positioning plate 6, and telescopic springs 8 are fixedly connected to both sides. Positioning rod 7 is slidably connected to positioning plate 6, and telescopic spring 8 is fixedly connected to positioning plate 6. By pulling positioning rod 7, parallel rod 10 can be moved to facilitate the placement of fitting 4. When positioning rod 7 is pulled to move parallel rod 10, telescopic spring 8 is compressed and stores force. After fitting 4 is placed, positioning rod 7 is released, and parallel rod 10 moves towards fitting 4 under the push of telescopic spring 8. After the protrusions on both sides press against the end face of fitting 4, fitting 4 can be kept parallel to base plate 1, which facilitates the precise positioning and processing of fitting 4.

[0026] Furthermore, the clamp includes anti-rotation racks 3 located on both sides of the fitting 4. The anti-rotation racks 3 are slidably connected to the base plate 1. One end of each anti-rotation rack 3 facing the fitting 4 has an arc surface that mates with the end face of the fitting 4. The other end of each anti-rotation rack 3 is provided with a pushing member capable of pushing the anti-rotation rack 3 inwards. The pushing member is used to push the anti-rotation rack 3 inwards to clamp the fitting 4. Figure 1 As shown, since the two sides of the fitting 4 are arc-shaped, when the anti-rotation rack 3 moves inward, the inner arc surface cooperates with the arc-shaped structure on both sides of the fitting 4, which can further improve the stability and firmness of the clamping of the fitting 4 and maintain the angle of the fitting 4 after it is clamped.

[0027] Furthermore, such as Figure 2 As shown, the pushing component includes a one-way clamp 2 and a two-way clamp 5. The end of the anti-rotation rack 3 away from the fitting 4 is provided with a pressing slope that is inclined towards the fitting 4. The ends of the one-way clamp 2 and the two-way clamp 5 facing the pressing slope are provided with a pushing slope that can slide with the pressing slope. When the one-way clamp 2 and the two-way clamp 5 move downward, the pressing slope is squeezed by the pushing groove, which can force the anti-rotation rack 3 to move towards the clamp, thereby clamping the clamp. The lower end of the base plate 1 corresponding to the one-way clamp 2 and the two-way clamp 5 is fixedly connected to a cylinder 13. The telescopic end of the cylinder 13 is fixedly connected to the corresponding one-way clamp 2 and the two-way clamp 5. The cylinder 13 is used to drive the one-way clamp 2 and the two-way clamp 5 to move vertically, thereby controlling the anti-rotation rack 3 to move inward to clamp and release the fitting 4.

[0028] Furthermore, the inner wall of the anti-rotation rack 3 is vertically provided with multiple anti-slip teeth. The anti-slip teeth are designed to increase the friction when clamping the fitting 4 and improve the clamping firmness of the fitting 4. In order to improve the accuracy of the parallel rod 10 pushing the fitting 4 to keep the fitting 4 parallel, the end of the protrusion facing the fitting 4 is provided with a tip. The tip pushes the fitting 4 to adjust its position. When adjusting the angle of the fitting 4, the tip makes point contact with the surface of the fitting 4, so that the fitting 4 is subjected to uniform force and the accuracy of the angle adjustment of the fitting 4 is enhanced.

[0029] like Figure 2 As shown, a handle 11 is fixedly connected to the end of the positioning pull rod 7 away from the hardware 4. The handle 11 is used to assist the user in pulling the positioning pull rod 7. A stop bar 12 is rotatably connected to one end of the handle 11. The stop bar 12 is arranged parallel to the positioning pull rod 7. After the positioning pull rod 7 is moved outward, the stop bar 12 can be rotated so that the stop bar 12 presses against the surface of the positioning plate 6. The movement of the positioning pull rod 7 can be restricted by the stop bar 12, which makes it convenient for the user to place the hardware 4.

[0030] Furthermore, to improve the stability of the parallel rod 10 during movement and to prevent the telescopic spring 8 from bending under compression, a sliding rod 9 is provided on the inner side of the telescopic spring 8. The sliding rod 9 is slidably connected to the positioning plate 6 along the axial direction, and one end of the sliding rod 9 is fixedly connected to the parallel rod 10. Under the limitation of the sliding rod 9, the parallel rod 10 can move stably while remaining parallel, and the support of the sliding rod 9 can prevent the telescopic spring 8 from bending after compression, thus improving the service life of the telescopic spring 8. In addition, support columns 14 are fixedly connected to the four corners of the bottom of the base plate 1. The height of the support columns 14 is greater than the height of the cylinder 13. In this application, the base plate 1 is supported by the support columns 14 during use. To reserve sufficient installation space for the cylinder 13, the stability of the base plate 1 can be ensured when the cylinder 13 is working, making it convenient for users to use the equipment designed in this application.

[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
