Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to an angle-adjustable angle grinder for producing end caps. Background Technology

[0002] In the field of pressure vessel manufacturing, end caps, as key sealing components of tanks, pipelines, and other equipment, directly affect the pressure-bearing performance and safety of the equipment due to their machining accuracy. During end cap production, the grinding process is crucial for ensuring weld quality, surface flatness, and dimensional accuracy. This is especially true in curved transition areas, beveling, and post-weld grinding, where grinding equipment needs flexible angle adjustment capabilities to adapt to the processing requirements of complex surfaces. With the increasing demands for standardization and high precision in pressure vessels from industries such as chemical and energy, traditional fixed-angle grinding equipment is no longer sufficient to meet the processing needs of end cap production under various operating conditions and with different curvatures.

[0003] Currently, traditional angle grinders have significant technical shortcomings in the production of end caps. On the one hand, conventional equipment uses a fixed-angle grinding wheel mounting structure, which cannot adjust the grinding angle according to the curvature of the end cap surface. This leads to situations where localized over-grinding or under-grinding occurs during processing. For example, when processing the circumferential weld at the connection between the end cap and the cylinder, the fixed-angle grinding wheel is difficult to conform to the arc transition surface, resulting not only in low grinding efficiency but also potential surface damage to the workpiece due to stress concentration.

[0004] In response to this technical problem, this application proposes an angle-adjustable angular grinding machine for head production. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an angle-adjustable angle grinder for end cap production. By dynamically adjusting the angle through a linked robotic arm, it is beneficial to accurately adapt to the complex curved surface of the end cap and achieve uniform grinding, avoiding the processing defects and rework problems caused by the fixed angle of traditional equipment. At the same time, the modular quick-release structure facilitates the quick replacement of the grinding head or maintenance of the main unit by hand, avoiding the problems of long downtime and high maintenance costs caused by the traditional bolt fixing method.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An adjustable angle grinder for end cap production includes a base platform. A base table is fixedly connected to the top of the base platform. A base joint is fixedly connected to the top of the base table by fixing bolts. A base joint is fixedly connected to the top of the base joint.

[0008] Furthermore, the fixing component includes clamp ear plates, which are fixedly connected to both ends of the clamping hoop, and the two clamp ear plates are connected by ear plate bolts.

[0009] Furthermore, the second rotating joint can drive the main robotic arm to rotate, the first rotating joint can drive the auxiliary robotic arm to rotate, and the top right side of the auxiliary robotic arm is provided with an adjusting joint, which can drive the transmission column to rotate through the main robotic arm.

[0013] Furthermore, the bottom of the base platform is provided with anti-slip rubber pads.

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

[0015] 1. In this utility model, multi-angle precise adjustment is achieved through linkage robotic arm, which is beneficial for operators to flexibly adjust the polishing angle according to the curvature of the end cap surface, avoiding the problems of uneven polishing or difficulty in adapting to curved surfaces caused by traditional fixed angle equipment, and significantly improving the processing accuracy and surface finish of complex workpieces.

In this utility model, the grinding head and the main body are connected by a modular fixing component, which facilitates the quick disassembly and replacement of worn parts or the switching of different specifications of grinding heads without tools.

[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] Reference Figures 1-2This utility model provides an embodiment of an adjustable angle grinder for end cap production, comprising a base platform 11, a base table 9 fixedly connected to the top of the base platform 11, a fixed seat 8 fixedly connected to the top of the base table 9 by fixing bolts 7, a base joint 12 fixedly connected to the top of the fixed seat 8, and a main robotic arm 3 rotatably connected to the base joint 12 via a second rotating joint 18. The main robotic arm 3 can pitch and swing around the second rotating joint 18 in the vertical plane to adjust the working height. Its working principle is that the second rotating joint 18, as a rotating structure connecting the base joint 12 and the main robotic arm 3, allows the main robotic arm 3 to change its angle in the vertical plane through the relative movement of the internal rotating joint, thereby adapting to grinding operations at different heights.

[0025] The main robotic arm 3 is rotatably connected to an auxiliary robotic arm 5 via a rotating joint 4 at its top. The front and rear ends of the auxiliary robotic arm 5 are rotatably connected to the rotating joint 4. The main robotic arm 3 is rotatably connected to the right side of the two rotating joints 4, forming a stable triangular structure that enhances the rigidity of the robotic arm. Utilizing the mechanical principle of triangle stability, the triangular shape formed by the main robotic arm 3, auxiliary robotic arm 5, and rotating joint 4 disperses forces during operation, preventing deformation of the robotic arm and ensuring operational accuracy. A connecting shaft 17 is fixedly connected to the front rotating joint 4. A transmission column 20 is rotatably connected to the outer wall of the connecting shaft 17. The transmission column 20 can rotate around the connecting shaft 17. The rear side of the transmission column 20 is connected to the main housing 13 via a fixing component, allowing the main housing 13 to be flexibly adjusted at multiple angles to adapt to the grinding requirements of different positions on the end cap. The connecting shaft 17 provides rotational support for the transmission column 20, allowing the transmission column 20 to rotate around it. Combined with the connection of the fixing component to the main housing 13, the main housing 13 can change its orientation with the transmission column 20, adapting to various grinding positions on the end cap.

[0026] Reference Figures 3-4The fixing components include clamp ear plates 16, which are fixedly connected to both ends of the clamping hoop 15. The two clamp ear plates 16 are threaded together by ear plate bolts 19. The tightness of the clamping hoop 15 can be adjusted by turning the ear plate bolts 19, enabling quick installation and disassembly of the main machine housing 13. Relying on the principle of threaded connection, turning the ear plate bolts 19 changes the spacing of the clamp ear plates 16, thereby adjusting the clamping force of the clamping hoop 15 on the main machine housing 13, achieving the purpose of quick assembly and disassembly. Rotating joint 2 18 can drive the main robotic arm 3 to rotate in the vertical plane, rotating joint 1 4 can drive the auxiliary robotic arm 5 to rotate in the horizontal or vertical direction, and adjusting joint 14 can drive the transmission column 20 to rotate through the main robotic arm 3. The three work together to achieve multi-angle adjustment, allowing the grinder to adapt to the grinding needs of different positions of the end cap. Based on the coordinated operation of multiple joint rotations, the second rotating joint 18, the first rotating joint 4, and the adjusting joint 14 drive the corresponding mechanical structural parts to rotate, changing the spatial position and angle of the grinding disc 1 to meet the grinding operations of different parts of the end cap. The grinding disc 1 is connected to the main body housing 13 through a transmission shaft.

[0027] Working Principle: When this angle-adjustable angle grinder is in operation, the operator is securely placed on the base platform 11, whose bottom anti-slip pads provide a non-slip foundation. The equipment achieves vertical pitch adjustment through the rotation of the main robotic arm 3 and its various joints. The auxiliary robotic arm 5 is connected to the top support of the main robotic arm 3 via rotating joint 4. The main housing 13 is connected to the rear of the rotatable transmission column 20 via a component consisting of a clamping hoop 15, clamping ear plates 16, and ear plate bolts 19, facilitating quick assembly / disassembly and fine-tuning of the angle. Multiple rotating mechanisms work together to achieve multi-angle precise positioning of the main housing 13, accurately adapting to the grinding of various positions on the curved surface of the end cap.

[0028] The front end of the transmission column 20 is connected to the second connecting column 25, which has a connecting component 21 for mounting the grinding head. The first connecting column 24 is connected to it via a buffer pad 22 and a limit buckle 23, which serves to reduce shock and prevent detachment. The dust collection box 10 on the rear side of the base platform 11 collects grinding dust. During adjustment, the corresponding rotating mechanism is operated to change the posture, the ear plate bolts 19 are turned to adjust the main body housing 13, the grinding head on the connecting component 21 is replaced, and the dust collection box 10 is cleaned. The anti-slip design of the base platform 11 ensures safe and stable operation.

[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
