Description

Technical Field

[0001] This utility model relates to the field of three-jaw clamp technology, and in particular to a three-jaw chuck for a round tube chamfering machine. Background Technology

[0002] In the field of round tube processing, chamfering is a key step to improve the quality of pipe ends, eliminate burrs and sharp edges to ensure the safety and smoothness of subsequent assembly. Most round tube chamfering machines use fixed clamps and simple positioning devices, which have problems such as poor adaptability to different pipe diameters, insufficient clamping stability leading to processing vibration, and low positioning accuracy causing chamfering dimension deviation. They are difficult to meet the requirements of modern production lines for high efficiency, high precision, and high compatibility.

[0003] Based on this, a three-jaw chuck specifically designed for round tube chamfering machines has emerged. Its split jaw structure enables radially uniform force clamping of the pipe fittings. Combined with precision guiding and self-centering functions, it can quickly adapt to various pipe diameters and ensure the concentricity of the pipe fittings during processing. At the same time, it integrates anti-slip texture and rigid support design to effectively suppress vibration and improve surface processing quality. It has become a core piece of equipment for improving the automation level and yield of round tube chamfering. However, the current three-jaw chucks are not adaptable to different pipe diameters. When facing frequent changes in pipe diameter specifications in mass production, the chuck needs to be changed frequently or complex adjustments need to be made, which greatly extends the production preparation time and reduces processing efficiency. Especially in small and medium batch multi-specification production scenarios, it will significantly increase the time cost and equipment investment of enterprises, thus failing to meet such usage requirements. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a special three-jaw chuck for round tube chamfering machines. It aims to improve the problem in the prior art that the chuck cannot be flexibly adjusted to match round tubes of different diameters. When facing frequent changes in tube diameter specifications during mass production, it is necessary to frequently change the chuck or perform complex adjustments, which greatly extends the production preparation time and reduces the processing efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a three-jaw chuck for a round tube chamfering machine, comprising a base plate, a circular hole on the front side of the base plate, a second circular plate fixedly connected to the inner side of the circular hole, a cylinder installed inside the second circular plate, a piston on the outer wall of the cylinder, a rocker arm rotatably connected to the outer wall of the piston, a first circular plate fixedly connected to the middle front side of the second circular plate, a sliding groove on the front side of the first circular plate, a limit groove on the inner side of the sliding groove, a slider on the front side of the outer wall of the rocker arm, and a gripper fixedly connected to the middle front side of the slider.

[0006] As a further description of the above technical solution:

[0007] An L-shaped plate is provided on the top of the outer wall of the circular plate, and bolts are threaded to the left and right sides of the top of the L-shaped plate. The bottom end of the bolts is threaded to the top of the outer wall of the circular plate.

[0008] As a further description of the above technical solution:

[0009] The bottom front side of the base plate is provided with reserved holes.

[0010] As a further description of the above technical solution:

[0011] Hanging rings are fixedly connected to the top left and right sides of the base plate.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the slider is slidably connected to the inner side of the groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the piston moves left and right by the inlet and outlet of gas, which in turn drives the rocker arm to swing. When the rocker arm swings, it pushes the slider to move up and down, so that the gripper connected to the slider slides outward along the inner side of the limiting groove and the sliding groove at the same time. This forms the gripper clamping and releasing principle. Since the piston moves and drives the rocker arm at the same time, the self-centering and clamping accuracy of the gripper are ensured when clamping, thus satisfying the stability when chamfering different round tubes, avoiding loosening, and improving the use effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model provides a three-jaw chuck for a round tube chamfering machine, including a base plate 1. A circular hole 13 is opened on the front side of the base plate 1. A circular plate 9 is fixedly connected to the inner side of the circular hole 13. A cylinder 15 is installed inside the circular plate 9. A piston 14 is provided on the outer wall of the cylinder 15. A rocker arm 8 is rotatably connected to the outer wall of the piston 14. A circular plate 6 is fixedly connected to the middle of the front side of the circular plate 9. A sliding groove 12 is opened on the front side of the circular plate 6. A limit groove 11 is opened on the inner side of the sliding groove 12. A slider 10 is provided on the front side of the outer wall of the rocker arm 8. A gripper 2 is fixedly connected to the middle of the front side of the slider 10. The outer wall of the slider 10 is slidably connected to the inner side of the sliding groove 12.

[0025] Specifically, a cylinder 15 is installed on the circular plate 2 9. The cylinder 15 serves as a power source, and the piston 14 on the outer wall performs reciprocating linear motion. The outer wall of the piston 14 is rotatably connected to the rocker arm 8. When the piston 14 moves under the drive of the cylinder 15, the rocker arm 8 will produce a corresponding swinging motion, realizing the effective transmission and conversion of power. These grooves 12 not only provide guidance for the swinging of the rocker arm 8, ensuring that the rocker arm 8 will not deviate during the movement, but also ensure the stability and reliability of the structure. A slider 10 is provided on the front side of the outer wall of the rocker arm 8. The slider 10 is tightly fitted with the groove 12 and the limiting groove 11, so that the swinging of the rocker arm 8 can be converted into the linear sliding of the slider 10 in the groove 12. The front middle of the slider 10 is fixedly connected to the gripper 2. When the slider 10 slides along the groove 12 under the drive of the rocker arm 8, the gripper 2 will open and close accordingly.

[0026] Please see the appendix Figure 3 - Appendix Figure 5The bottom front side of the base plate 1 is provided with reserved holes 7. The top of the outer wall of the circular plate 6 is provided with an L-shaped plate 5. The top left and right sides of the L-shaped plate 5 are threaded with bolts 4. The bottom end of the bolts 4 is threaded with the top of the outer wall of the circular plate 6. The top left and right sides of the base plate 1 are fixedly connected with hanging rings 3.

[0027] Specifically, the L-shaped plate 5 provides support and fixing points above the circular plate 6. The top left and right sides of the L-shaped plate 5 are threaded and bolts 4 are securely installed. The bottom ends of these bolts 4 are precisely threaded to the top of the outer wall of the circular plate 6. By rotating the bolts 4, the L-shaped plate 5 and the circular plate 6 can be tightly fixed and flexibly disassembled. The top left and right sides of the base plate 1 are fixedly connected with hanging rings 3, which can withstand a certain amount of tension.

[0028] Working principle: The piston 14 moves left and right due to the inflow and outflow of gas, which in turn drives the rocker arm 8 to swing. When the rocker arm 8 swings, it pushes the slider 10 to move up and down, causing the gripper 2 connected to the slider 10 to slide outward along the inner side of the limiting groove 11 and the sliding groove 12. This forms the clamping and releasing principle of the gripper 2. Since the piston 14 moves and drives the rocker arm 8 at the same time, it ensures the self-centering and clamping accuracy of the gripper 2 when clamping, thereby meeting the stability requirements when chamfering different round tubes, avoiding loosening, and improving the use effect.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
