Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and in particular to a positioning device for preventing deformation during the processing of a water and electricity plug-in base plate. Background Technology

[0002] The base plate for the hydroelectric plug is a long, thin aluminum structure. Its thinness results in insufficient overall rigidity, and residual internal stress from the rolling process leads to an initial planar deformation of 0.5mm upon leaving the factory. This component requires processing to meet stringent requirements: flatness ≤0.1mm and hole / edge distance accuracy ±0.05mm. However, existing anti-deformation positioning devices for hydroelectric plug base plates mostly use a single rigid clamp. The small contact area between the clamping element and the long, thin aluminum base plate easily leads to localized pressure concentration, directly causing extrusion deformation of the base plate. Simultaneously, vibrations generated during processing are directly transmitted to the base plate through the rigid structure, causing blade vibration and further amplifying the deformation. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the contact area between the clamping part and the long and thin aluminum base plate is small, which easily leads to local pressure concentration and directly causes the base plate to be squeezed and deformed. To this end, we propose a deformation-proof positioning device for processing water and electricity plug-in base plates.

[0004] To achieve the above objectives, this application adopts the following technical solution: a deformation-resistant positioning device for processing a water and electricity plug-in base plate, comprising a base, wherein a cylinder positioning component, a hydraulic cylinder auxiliary support component, and a cylinder clamping assembly are fixedly installed on the upper wall of the base, wherein four sets of hydraulic cylinder auxiliary support components are provided, and the four sets of hydraulic cylinder auxiliary support components are rectangularly distributed in the support area of ​​the base, and three sets of cylinder clamping assemblies are provided, wherein the three sets of cylinder clamping assemblies are distributed in a distributed layout, wherein two sets of cylinder clamping assemblies are symmetrically arranged on both sides of the same end face of the base, and the other set of cylinder clamping assemblies is separately located in the middle of the opposite end face of the base.

[0005] Furthermore, the cylinder clamping assembly includes a cylinder body and a lower support fixedly installed on the upper wall of the base. An upper mounting plate is fixedly connected to the upper wall of the cylinder body. A pressure block body is axially connected to the output end of the cylinder body. Side mounting plates are axially connected to both sides of the pressure block body. The lower end of the side mounting plate is axially connected to the upper mounting plate.

[0006] Furthermore, the side mounting plate is assembled at the middle position of the pressure block body.

[0007] Furthermore, a movable groove is provided on the lower wall of the end of the pressure block body away from the cylinder body, and a middle connecting block is slidably connected to the inner wall of the movable groove. An extension clamp is installed on the lower wall of the middle connecting block and the upper wall of the lower support.

[0008] Furthermore, a rubber elastic block is fixedly connected to the upper end of the intermediate block, and the upper end of the rubber elastic block is fixedly connected to the top of the cavity of the movable groove.

[0009] Furthermore, a rubber anti-slip pad is fixedly connected to the lower end of the extension clamp, and multiple sets of the rubber anti-slip pad are provided, with all sets of the rubber anti-slip pad arranged and distributed on the lower wall of the extension clamp.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] In this invention, a stable supporting force is applied by a hydraulic cylinder auxiliary support component. The trapezoidal layout makes the support strength in the middle higher than that at both ends, accurately offsetting the tendency of warping in the middle that is prone to occur during the processing of long and thin materials. At the same time, the evenly distributed support points disperse the weight of the base plate and the cutting force, providing basic support for preventing deformation. Subsequently, three sets of cylinder clamping components are activated to clamp in coordination. Two sets of cylinders located on both sides of the same end face and one set of cylinders in the middle of the opposite end face form a cross-force. Through the layout of side clamps at both ends and a single-end center clamp, stress shift caused by clamping in one direction is avoided. Through the triple combination of optimized support layout, expanded clamping area, and vibration buffering and absorption, the problem of small contact area between the clamping component and the long and thin aluminum base plate, which easily leads to local pressure concentration and directly causes the base plate to be squeezed and deformed, is solved. At the same time, the vibration generated during processing is directly transmitted to the base plate through the rigid structure, causing the vibration phenomenon and further amplifying the deformation amplitude.

[0018] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0019] Reference Figures 1-4 As shown, in order to address the problem that the small contact area between the clamping component and the long, thin aluminum base plate easily leads to localized pressure concentration, directly causing extrusion deformation of the base plate, and that vibrations generated during processing are directly transmitted to the base plate through the rigid structure, causing tool vibration and further amplifying the deformation, the following preferred technical solutions are provided:

[0020] A deformation-resistant positioning device for processing a pluggable base plate for hydroelectric applications includes a base 1. A cylinder positioning component 2, a hydraulic cylinder auxiliary support component 3, and a cylinder clamping assembly 4 are fixedly installed on the upper wall of the base 1. Four sets of hydraulic cylinder auxiliary support components 3 are distributed in an isosceles trapezoidal shape within the support area of ​​the base 1. This layout allows the support force to be evenly distributed along the length of the base plate, with a focus on strengthening the support strength of the easily warped central area, effectively counteracting the deformation tendency caused by cutting forces and clamping forces. The three sets of cylinder clamping assemblies 4 adopt a distributed layout, with two sets symmetrically arranged on both sides of the same end face of the base 1, and the other set separately located in the middle of the opposite end face of the base 1. Through cross-end face coordinated clamping, a bidirectional balanced force is formed, avoiding stress shift caused by clamping on a single end face, and reducing the risk of deformation from the clamping layout.

[0021] The cylinder clamping assembly 4 includes a cylinder body 41 and a lower support 42 fixedly mounted on the upper wall of the base 1. An upper mounting plate 43 is fixedly connected to the upper wall of the cylinder body 41. A pressure block body 44 is axially connected to the output end of the cylinder body 41. Side mounting plates 45 are axially connected to both sides of the pressure block body 44. The lower end of the side mounting plates 45 is axially connected to the upper mounting plate 43. The side mounting plates 45 are assembled at the middle position of the pressure block body 44. This connection method allows the clamping force to be evenly transmitted to the side mounting plates 45 through the middle position, ensuring the stability and force balance of the clamping structure.

[0022] The lower wall of the pressure block body 44, away from the cylinder body 41, has a movable groove 46. A middle connecting block 47 is slidably connected to the inner wall of the movable groove 46. An extension clamping plate 48 is installed on the lower wall of the middle connecting block 47 and the upper wall of the lower support 42. The extension clamping plate 48 can significantly increase the contact area with the base plate, disperse the clamping pressure, and avoid extrusion deformation caused by excessive local pressure. The sliding fit between the middle connecting block 47 and the movable groove 46 can adapt to the slight deformation difference of the base plate, realize flexible clamping, and reduce stress damage caused by rigid extrusion.

[0023] A rubber elastic block 49 is fixedly connected to the upper end of the intermediate connecting block 47, and the upper end of the rubber elastic block 49 is fixedly connected to the top of the cavity of the movable groove 46. The rubber elastic block 49 has an elastic buffer function, which can absorb the vibration energy transmitted during processing, suppress the occurrence of knife vibration, and can adaptively adjust the position of the intermediate connecting block 47 according to the clamping pressure to further optimize the clamping fit and force balance.

[0024] A rubber anti-slip pad 410 is fixedly connected to the lower end of the extension clamping plate 48. Multiple sets of rubber anti-slip pads 410 are evenly distributed on the lower wall of the extension clamping plate 48. The rubber anti-slip pad 410 can increase the friction with the surface of the base plate, prevent the base plate from shifting during processing, and ensure positional accuracy. At the same time, its softness can avoid scratching the surface of the base plate during clamping, and can further disperse the contact pressure, thus improving the anti-deformation effect.

[0025] Specifically, during processing, the long, thin aluminum base plate is first placed in the positioning area of ​​the base 1. The initial reference positioning is completed by the cylinder positioning component 2, and the stable support force is applied by the hydraulic cylinder auxiliary support component 3. The trapezoidal layout makes the support strength in the middle higher than that at both ends, which accurately counteracts the tendency of warping in the middle that is prone to occur during the processing of long, thin materials. At the same time, the weight of the base plate and the cutting force are dispersed by the evenly distributed support points, providing basic support for preventing deformation.

[0026] Subsequently, the three sets of cylinder clamping assemblies 4 start to clamp in coordination. The two sets of cylinders located on both sides of the same end face and the set of cylinders in the middle of the opposite end face form a cross-force. Through the layout of the two-end side clamps and the single-end center clamp, stress shift caused by clamping in one direction is avoided. During the clamping process, the cylinder body 41 drives one end of the pressure block body 44 to move upward. The side mounting plate 45 rotates synchronously due to the shaft connection structure. With the help of the connection point of the middle assembly, the other end of the pressure block body 44 is pressed down. At this time, the lower support 42 and the extended clamping plate 48 on the middle connecting block 47 form an upper and lower clamping. By increasing the contact area, the local pressure is distributed to the entire clamping plate area.

[0027] During processing, the rubber elastic block 49 absorbs the vibration transmitted by the machine tool through elastic deformation, blocking the transmission path of the vibration energy from the vibrating knife to the base plate. On the other hand, it adaptively adjusts the position of the intermediate block 47 according to the slight deformation of the base plate, achieving a balance between rigid positioning and flexible compensation, and avoiding extrusion deformation caused by rigid clamping. At the same time, multiple sets of rubber anti-slip pads 410 not only limit the movement of the base plate through friction to ensure positional accuracy, but also further disperse pressure through flexible contact. Finally, through the triple combination of optimized support layout, expanded clamping area, and vibration buffering and absorption, the problem of small contact area between the clamping parts and the long and thin aluminum base plate, which easily leads to local pressure concentration and directly causes extrusion deformation of the base plate, and the vibration generated during processing is directly transmitted to the base plate through the rigid structure, causing the vibration phenomenon and further amplifying the deformation amplitude, is solved.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
