Description

Technical Field

[0001] This utility model belongs to the field of automotive processing technology, specifically, it relates to a tooling for flipping and clamping automotive parts. Background Technology

[0002] In the processing of automotive parts, some processes that require processing on both sides, such as painting, coating, sheet metal grinding and polishing, require the workpiece to be flipped in automated processing equipment before processing. Some workpieces are too long on the wide side and can easily hit the worktable during flipping, damaging the workpiece.

[0003] Utility model CN220145884U discloses a flipping fixture for processing automotive parts, including a worktable. A mechanical drive box is located at the bottom of the worktable, and a drive motor is located in the middle of the upper part of the mechanical drive box. The end faces of the worktable are symmetrically equipped with lifting and flipping mechanisms for flipping, clamping, and adjusting the height of automotive parts. A U-shaped clamping plate on one side of the mounting plate clamps both ends of the automotive parts. The workpiece clamping cylinder, clamping pad, buffer air cushion, and anti-slip clamping plate work together to clamp and fix both ends of the automotive parts. This allows the flipping fixture to be laterally adjusted according to the size and thickness of the automotive parts, improving the clamping and flipping effect for automotive parts of different sizes and thicknesses, thus increasing the scope of application and practicality of the flipping fixture for clamping and flipping automotive parts. However, existing clamping devices lack quick-release designs for the flipping power transmission and clamping components, and the lateral adjustment power path is lengthy, significantly increasing maintenance difficulty and adaptation time. On the one hand, the tilting motor is directly fixed to one side of the mounting vertical plate, and its shaft is rigidly connected to the U-shaped clamping plate. If it is necessary to replace the clamping components to adapt to different parts or to repair the tilting motor, it is necessary to first disassemble the connection between the mounting vertical plate and the horizontal moving plate, and separate the lifting cylinder from the mounting vertical plate. The disassembly and assembly steps are cumbersome, making it impossible to quickly switch clamping tools and difficult to meet the rapid changeover requirements of diversified processing of automotive parts. On the other hand, the horizontal adjustment relies on a long path transmission of "drive motor → bevel gear → positive / negative threaded screw → horizontal moving drive rod", which involves multiple sets of gear meshing and screw transmission. After long-term use, if the bevel gear wears or the screw thread clearance increases, it is easy to cause the horizontal moving plates on both sides to adjust asynchronously, which in turn causes the clamping center of the U-shaped clamping plate to shift, affecting the subsequent tilting accuracy, and even causing the parts to slip during the tilting process. In view of this, this utility model is proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A clamping fixture for flipping and clamping automotive parts includes: A flipping component, which provides flipping power to drive automotive parts to rotate around a fixed axis, thereby adjusting the processing angle of the parts. A clamping component is fixedly installed on the flipping plate of the flipping component and flips synchronously with the flipping component. It is used to clamp and fix the automotive parts to prevent the parts from shifting during flipping or processing. The flipping component transmits power through a quick-release structure, and the clamping component is driven synchronously by two cylinders, causing the two clamping plates to move towards each other, together forming an integrated flipping-clamping auxiliary tooling for automotive parts processing.

[0005] Preferably, the flipping component includes a motor base, a geared motor, a connector, a flipping seat, a rotating shaft, and a flipping plate; The motor base is a plate-shaped or frame-type structure used to fix and support the geared motor, ensuring the stability of the geared motor during operation. The geared motor is fixed on the motor base, with its output shaft facing the tilting seat, and is used to output controllable tilting torque to adjust the tilting speed and angle; The connector is mounted on the output shaft of the geared motor and adopts a quick-release structure for quick connection or disconnection of the shaft; The flipping seat is a support structure, fixed to an external processing platform or base, used to rotate and support the rotating shaft; One end of the rotating shaft is quickly connected to the connector, and the other end is rotatably engaged with the flip seat, allowing it to rotate around its own axis under the drive of the connector. The flipping plate is a rectangular plate or a plate adapted to the shape of the parts. One side is fixedly connected to the rotating shaft and flips synchronously with the rotating shaft. The other side is used to fix and install the clamping parts, so as to realize the linkage between the clamping parts and the flipping parts.

[0006] Preferably, the clamping component includes a mounting shell, a cylinder, an air pipe connector, a guide groove, a movable block, and a clamping plate; The mounting shell is a hollow frame structure, fixed to the flip plate of the flipping component. The interior of the mounting shell is provided with a groove, and a guide groove extending along the length of the mounting shell is opened in the middle of one side. Two cylinders are provided, symmetrically embedded in the groove of the mounting shell, with the output end of the cylinder facing the guide groove. The two cylinders are connected to the same air source through an air pipe connector to achieve synchronous drive. The air pipe connector is fixed to the air inlet end of the cylinder and is used to connect an external air pipe to provide compressed air to the cylinder. Two movable blocks are provided, symmetrically slidably disposed in the guide groove of the mounting shell. The inner sides of the two movable blocks are respectively fixedly connected to the output ends of two cylinders, and can slide along the guide groove under the drive of the cylinders. The clamping plate is a plate body adapted to the contour of the automotive parts and is fixed to the outside of the movable block. When the two cylinders extend and retract synchronously, they drive the two movable blocks to move towards or away from each other along the guide groove, thereby causing the two clamping plates to clamp the parts towards each other or release the parts away from each other synchronously.

[0007] Preferably, the geared motor is a reversible stepper motor, and the flipping angle can be adjusted by the control system to meet the angle requirements of different machined surfaces of automotive parts; The quick-release structure of the connector and the shaft is equipped with a positioning pin or anti-slip buckle to ensure the stability of power transmission after connection and to prevent relative sliding between the shaft and the connector. The rotating base is equipped with a bearing at the joint with the rotating shaft to reduce frictional resistance when the rotating shaft rotates, ensuring a smooth and uninterrupted rotating process.

[0008] Preferably, the outer side of the clamping plate is provided with an elastic buffer layer to buffer the clamping force, avoid damaging the surface of the automotive parts, and at the same time enhance the friction between the clamping plate and the parts, thereby improving the clamping stability. The inner wall of the guide groove is provided with a lubricating layer to reduce the sliding friction between the movable block and the guide groove and ensure smooth movement of the movable block; A sealing gasket is provided between the groove of the mounting shell and the cylinder to prevent coolant and debris from entering the cylinder during processing, thereby extending the service life of the cylinder.

[0009] Preferably, the flip plate of the flipping component is provided with multiple mounting holes, and the mounting position of the clamping component on the flip plate can be adjusted according to the size of the automotive parts and the clamping requirements. The clamping component has two cylinders equipped with a synchronization valve to ensure that the extension and retraction speeds and strokes of the two cylinders are completely consistent, thus avoiding the clamping deviation of the parts due to asynchronous cylinder actions. The motor base of the flipping component is equipped with a horizontal adjustment bolt, which can be used to finely adjust the horizontal position of the reduction motor, ensuring the coaxiality of the connector and the rotating shaft, and improving the flipping transmission accuracy.

[0010] Compared with the prior art, the present invention has the following advantages: This utility model, through its quick-release power transmission and modular installation design, completely solves the problems of cumbersome disassembly and assembly and poor adaptability of existing devices. In the power transmission stage, the output shaft of the geared motor of the flipping component is connected to the rotating shaft through a quick-release connector. When replacing the rotating shaft, flipping plate, or repairing the geared motor, there is no need to disassemble the flipping base and the external platform; only the connector needs to be separated for quick disassembly. The disassembly and assembly efficiency is significantly improved compared to existing patents. At the same time, the flipping plate has multiple mounting holes, and the clamping component can be flexibly adjusted to adjust the installation position according to the size and shape of the automotive parts. There is no need to redesign the flipping plate structure, and the adaptability range covers a variety of parts from small bolts to large irregular brackets. In terms of clamping adaptation, the clamping plate and the movable block of the clamping component are detachably connected. For irregular parts such as arcs and curved surfaces, only the clamping plate with the corresponding contour needs to be replaced, without modifying the entire clamping component. The modular design greatly reduces the changeover cost and meets the rapid switching needs of diversified processing of automotive parts.

[0011] This invention employs a dual design of synchronous control and meticulous protection to construct a more reliable clamping system. Its stability and safety far surpass existing devices. For synchronous control, the two cylinders of the clamping component are equipped with dedicated synchronous valves to ensure that compressed air enters both cylinders simultaneously, achieving synchronized opposite-facing / opposite-facing movement of the moving block and the clamping plate. This prevents clamping offset caused by asynchronous cylinder movements. Simultaneously, the cylinder output end is rigidly connected to the moving block, and with the guide groove limiting the moving block, the precise movement trajectory of the clamping plate is further guaranteed. Even during flipping, the components maintain center alignment. Displacement can occur due to clamping deviation. In terms of detailed protection, the elastic buffer layer on the outside of the clamping plate can conform to the surface of the parts and produce slight deformation, which not only avoids scratch damage to the surface of the parts caused by hard clamping, but also increases the clamping friction to prevent slippage during flipping; the lubrication layer on the inner wall of the guide groove reduces the sliding resistance of the moving block and ensures smooth clamping without jamming; the sealing gasket between the mounting shell and the cylinder can prevent coolant and metal chips from entering the cylinder during the processing, avoiding cylinder corrosion or jamming and extending the service life of the equipment. These detailed optimizations together improve the long-term reliability and processing safety of the tooling.
