Technical Field
[0001] This utility model relates to the technical field of positioning and clamping devices, and in particular to a positioning and clamping device for engine parts. Background Technology
[0002] With the continuous development of industrial technology, the performance and efficiency of engines, as the core component of mechanical power, have always been a key research focus in the industrial field. In the engine manufacturing process, precise positioning and clamping of parts are crucial steps to ensure engine performance and lifespan. Traditional engine part positioning and clamping devices have the following problems: traditional positioning and clamping devices often rely on manual adjustment, resulting in low positioning accuracy, which is difficult to meet the high-precision requirements of modern engine manufacturing; because the application of clamping force depends on the operator's experience and strength, the clamping force is unstable, which may damage engine parts or affect their processing quality; manually operated positioning and clamping devices have significant inefficiencies, especially in mass production, and cannot meet the demands of rapid and continuous production.
[0003] Therefore, an engine part positioning and clamping device is provided. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and improve the processing quality and production efficiency of engine parts. It is necessary to develop a new type of engine part positioning and clamping device. This device should have the characteristics of high-precision positioning, stable clamping force, high operating efficiency, good adaptability and high degree of automation, so as to solve the problems existing in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] This utility model discloses an engine part positioning and clamping device, comprising a base, characterized in that: the base has an L-shaped bent structure, a cylinder assembly is fixedly installed on the bottom surface of the base, two fixed shaft assemblies are installed on the side wall of the base, a left clamping block and a right clamping block are respectively connected to the two fixed shaft assemblies, a rotating block one is provided on one side of the left clamping block, and a rotating block two is provided on one side of the right clamping block, one end of the rotating block one and one end of the rotating block two are respectively hinged by a connecting block, and the output end of the cylinder assembly is hinged to the lower end of the right clamping block.
[0007] As a preferred embodiment of the present invention, the cylinder assembly includes a fixed base and a cylinder. The fixed base is fixedly installed on the upper surface of the base. The upper end of the fixed base is hinged to one end of the cylinder, and the output end of the cylinder is hinged to the lower end of the right clamping block.
[0008] As a preferred technical solution of this utility model, the fixed shaft assembly includes an inner shaft and an outer shaft. The inner shaft passes through the side wall of the base and the outer shaft in sequence and is fixedly connected to the rotating block. One end of the inner shaft is threaded with a nut, and the cotter pin passes through the nut and is placed inside the inner shaft.
[0009] As a preferred technical solution of this utility model, the fixed shaft assembly includes an inner shaft and an outer shaft. The inner shaft passes through the side wall of the base and the outer shaft in sequence and is fixedly connected to the rotating block 2. One end of the inner shaft is threaded with a nut, and the cotter pin passes through the nut and is placed inside the inner shaft.
[0010] As a preferred embodiment of this utility model, one end of both the first rotating block and the second rotating block is triangular pyramidal, and the axes of symmetry of the first rotating block and the second rotating block are perpendicular to each other.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] First, the cylinder is reset. At this point, the cylinder output retracts back to its original position, causing the lower end of the right clamping block to rotate to the left. Simultaneously, the upper end of the right clamping block rotates to the right, opening the clamping device. The right clamping block rotates clockwise during reset, causing rotating block two to also rotate clockwise. Since the connecting block is higher on the left and lower on the right, rotating block two's clockwise rotation lifts the connecting block, causing rotating block one to rotate counter-clockwise. When reset to the original position, rotating block two rotates to the leftmost position, and rotating block one rotates to the topmost position, reaching the maximum opening angle. Then, the engine parts are delivered to their positions, the cylinder starts, and the lower end of the right clamping block is pushed to the right, causing it to rotate counter-clockwise. Similarly, rotating block two also rotates counter-clockwise. When rotating counterclockwise, rotating block two pulls one end of the connecting block downwards, causing rotating block one to rotate clockwise. The opening angle of the left and right clamping blocks gradually decreases, thus clamping the part. When the cylinder pushes to its maximum extension, rotating block two rotates to the bottom and rotating block one rotates to the rightmost end. This positioning and clamping device, through the cylinder's pushing design, combined with the rotation of the fixed shaft assembly and the left and right clamping blocks, effectively improves the stability and production efficiency of engine parts during processing. When the engine part is in place, the starting cylinder can automatically clamp it, resulting in higher positioning accuracy and stable clamping force. This device should have the characteristics of high-precision positioning, stable clamping force, high operating efficiency, good adaptability, and high automation. Attached Figure Description

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0020] like Figure 1-3As shown, this utility model discloses an engine part positioning and clamping device, including a base 1. The base 1 has an L-shaped bent structure. A cylinder assembly 2 is fixedly installed on the bottom surface of the base 1. Two fixed shaft assemblies 3 are installed on the side wall of the base 1. A left clamping block 4 and a right clamping block 5 are respectively connected to the two fixed shaft assemblies 3. A rotating block 6 is provided on one side of the left clamping block 4, and a rotating block 7 is provided on one side of the right clamping block 5. One end of the rotating block 6 and one end of the rotating block 7 are respectively hinged by a connecting block 8. The output end of the cylinder assembly 2 is hinged to the lower end of the right clamping block 5. The cylinder assembly 2 drives the right clamping block 5 to swing left and right, thereby opening and closing the upper end of the right clamping block 5 with the left clamping block 4, thereby achieving the purpose of clamping.
[0021] Furthermore, the cylinder assembly 2 includes a fixed base 201 and a cylinder 202. The fixed base 201 is fixedly installed on the upper surface of the base 1. The upper end of the fixed base 201 is hinged to one end of the cylinder 202. The output end of the cylinder 202 is hinged to the lower end of the right clamping block 5. By extending and retracting the output end of the cylinder 202, the right clamping block 5 is driven to swing left and right, thereby achieving the purpose of clamping the right clamping block 5 with the left clamping block 4.
[0022] The fixed shaft assembly 3 includes an inner shaft 301 and an outer shaft 302. The inner shaft 301 passes through the side wall of the base 1 and the outer shaft 302 in sequence and is fixedly connected to the rotating block 6 or the rotating block 7. That is, the fixed shaft assembly 3 is connected to the rotating block 6 or the rotating block 7 in the same way. One end of the inner shaft 301 is connected to a nut, which limits the inner shaft 301. The inner shaft 301 is connected to the nut through a cotter pin 303, which limits the inner shaft. At this time, the cotter pin 303 can make a fine adjustment of the angle of the inner shaft 301 by passing through the inner shaft 301 and the nut at different angles, thereby finely adjusting the angle of the rotating block 6 or the rotating block 7. One end of the rotating block 6 and the rotating block 7 are both triangular pyramidal. The axes of symmetry of the rotating block 6 and the rotating block 7 are perpendicular to each other. The rotating block 6 and the rotating block 7 are connected by a connecting block 8. That is, when the rotating block 7 rotates, the rotating block 6 can be adjusted accordingly.
[0023] Specifically, in use, first reset cylinder 202. At this time, the output end of cylinder 202 retracts back to the origin, causing the lower end of the right clamping block 5 to rotate to the left. At this time, the upper end of the right clamping block 5 rotates to the right, and the clamping device is in the open state. When the right clamping block 5 is reset, it rotates clockwise, which will also cause rotating block 7 to rotate clockwise. Since the connecting block 8 is higher on the left and lower on the right at this time, when rotating block 7 rotates clockwise, it will lift the connecting block 8, causing rotating block 6 to rotate counterclockwise. When reset to the origin, rotating block 7 rotates to the leftmost end, and rotating block 6 rotates... At the top, the maximum opening angle is reached. Then, the engine parts are delivered to the position, cylinder 202 starts, pushing the lower end of the right clamping block 5 to the right, causing it to rotate counterclockwise. Similarly, rotating block 7 also rotates counterclockwise. When rotating block 7 rotates counterclockwise, it pulls one end of connecting block 8 downward, causing rotating block 6 to rotate clockwise. The opening angle of the left clamping block 4 and the right clamping block 5 gradually decreases, thus clamping the parts. When cylinder 202 pushes to the maximum extension, rotating block 7 rotates to the bottom and rotating block 6 rotates to the rightmost end (e.g., ...). Figure 3 As shown, this positioning and clamping device, through the pushing design of cylinder 202, in conjunction with the rotation of fixed shaft assembly 3, left clamping block 4 and right clamping block 5, effectively improves the stability and production efficiency of engine parts during processing. When the engine parts are in place, starting cylinder 202 can automatically clamp them, resulting in higher positioning accuracy and stable clamping force. This device should have the characteristics of high-precision positioning, stable clamping force, high operating efficiency, good adaptability and high degree of automation.
[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
