TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile parts, specifically to a cylindrical automobile parts deburring positioning structure. BACKGROUND
[0002] Automobile parts are necessary factors to support the sustainable and healthy development of the automobile industry. The parts and components directly obtained by conventional machining processes are the units that constitute the whole of automobile parts machining and the products that serve automobile parts machining. As the foundation of the automobile industry, the surface of the parts is prone to residual burrs, which need to be removed by cutting or grinding.
[0003] However, the existing deburring positioning structure still has some shortcomings in actual use. Although the existing deburring positioning structure is provided with a clamping structure to position the parts, it is clamped and positioned on both sides. The clamping force of two-sided clamping is concentrated on two opposite positions, which is easy to cause uneven stress distribution on the parts. When the clamping force is large, local deformation may occur near the clamping point, especially for cylindrical parts with low hardness or thin walls. This deformation may be more obvious. Moreover, two-sided clamping has relatively poor adaptability to shape and size, and it relies on the precise contact of two opposite planes to achieve positioning and clamping. If the cylindricality of the parts is not high or the size has certain deviation, it may cause problems such as loose clamping or poor contact.
[0004] Therefore, we designed a cylindrical automobile parts deburring positioning structure to solve the above problems. UTILITY MODEL CONTENTS

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0022] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a cylindrical automobile parts deburring positioning structure, including workbench 1, the top of workbench 1 is fixedly connected with X-shaped plate 2, X-shaped plate 2 is clamped with clamping plate 3 slidingly, the top of clamping plate 3 is fixedly connected with support 4, the middle of X-shaped plate 2 is fixedly connected with base 6, rotating shaft 7 is rotatably connected in base 6, the top of rotating shaft 7 is fixedly connected with rotating disc 8, the four corners of rotating disc 8 are fixedly connected with pin shaft 9, pin shaft 9 is fixedly connected with arc-shaped connecting rod 10, the other end of arc-shaped connecting rod 10 is fixedly connected on support 4, the top of support 4 is fixedly connected with clamping plate 5, the bottom of rotating shaft 7 is connected with motor 11, motor 11 is fixedly connected at the bottom of workbench 1.
[0023] When being implemented specifically, start motor 11, motor 11 will drive rotating shaft 7 and rotating disc 8 to rotate, while rotating shaft 7 and rotating disc 8 rotate, pin shaft 9 on rotating disc 8 drives four arc-shaped connecting rods 10 to move, then clamping plate 3 and support 4 will slide inwards along X-shaped plate 2, four clamping plates 5 will also move inwards to approach the part and clamp and fix the part, and motor 11 is a speed reducer, the speed reducer can realize multi-stage speed regulation by changing the combination mode of gear or adjusting input parameter, when it is necessary to slowly and accurately deburr cylindrical automobile parts, the speed reducer can provide suitable low-speed drive to ensure that the movement speed of deburring tool meets the requirements.
[0024] Please refer to Figures 1-4 The number of clamping plate 3, support 4 and clamping plate 5 is four, and four clamping plate 3, support 4 and clamping plate 5 are respectively arranged at the four ends of X-shaped plate 2.
[0025] When being implemented specifically, four clamping plates 5 can clamp and hold the part from four sides by moving inwards with clamping plate 3, and the force distribution is more uniform, so that the clamping force can be better dispersed, and for cylindrical parts, uniform clamping force can effectively avoid deformation caused by excessive local stress.
[0026] See Figures 1-4 There are also four arc-shaped connecting rods 10, with one end of two of the arc-shaped connecting rods 10 fixedly connected to the bottom end of the pin 9, and one end of the other two arc-shaped connecting rods 10 fixedly connected to the top end of the pin 9.
[0027] In practice, the different positions of two adjacent arc-shaped connecting rods 10 can prevent motion interference when the arc-shaped connecting rods 10 move.
[0028] See Figures 1-4 The inner wall of the clamp 5 is fixedly connected with a contact 12. There are multiple contacts 12. Each contact 12 includes a fixed end 13 and a sliding end 14. A spring 15 is fixedly connected inside the fixed end 13. The other end of the spring 15 is fixedly connected to the sliding end 14. The sliding end 14 is slidably connected inside the fixed end 13.
[0029] In practice, when the clamping plate 5 clamps the component, the contact point 12 on the clamping plate 5 first contacts the component. If the cylindricity of the component is not ideal or there are local protrusions or depressions on the surface, the retractable contact point 12 can adapt to these shape changes by its own extension and retraction.
[0030] See Figures 1-4 The sliding end 14 is shaped like a parabolic cone with a larger inner diameter and a smaller outer diameter, and the material of the sliding end 14 is polyurethane.
[0031] In practice, this shape can better adapt to the slight irregularities on the surface of the parts. Since the surface of the parabolic cone is a continuously changing curve, when the surface of the parts has small protrusions, depressions or unevenness, the contact end can fit the parts with different contact angles and areas. Polyurethane has high hardness, good elasticity, and excellent tear resistance and wear resistance.
[0032] See Figures 1-4 The bottom of the workbench 1 is provided with four support legs 16, and the four support legs 16 are respectively fixedly connected to the four corners of the bottom of the workbench 1.
[0033] In practice, the four support legs 16 are located at the four corners of the bottom of the workbench 1, forming a stable quadrilateral support structure that can evenly distribute the pressure to the four support points. This uniform pressure distribution can effectively prevent the workbench 1 from tilting or shaking during operation.
