Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, and in particular relates to a flipping tool for processing automotive plate-shaped parts. Background Technology

[0002] Automotive sheet metal parts refer to thin, regularly shaped metal or non-metal sheet metal parts widely used in automobile manufacturing and assembly. They are usually made of steel plates, aluminum plates or other alloy materials through processes such as stamping, cutting, and bending. They have a certain structural strength and rigidity and are used to form part of the automobile body structure, body panels, interior support parts and functional components, such as door inner panels, engine hoods, floors, wheel covers, trunk partitions, bracket connecting plates, etc.

[0003] The existing processing of sheet metal parts for automobiles lacks a flipping fixture capable of fixing and flipping sheet metal parts of different sizes. The problem with the aforementioned technology is that in the processing of sheet metal parts for automobiles, there is a lack of a dedicated tooling equipment that can adapt to multiple sizes and specifications and achieve stable clamping and synchronous flipping. Due to the wide variety of sheet metal parts and their different shapes, existing clamping devices are often only suitable for parts within a specific size range, making it difficult to meet the requirements for precise positioning and reliable fixing of parts of different specifications during the processing. Especially when it is necessary to adjust the angle of the parts or process them on both sides, traditional tooling cannot achieve fast and stable flipping operations, resulting in low processing efficiency. In fact, unstable clamping may even cause parts to shift, deform, or have processing errors, affecting product quality and production safety. In addition, frequent changes of fixtures not only increase the complexity of operation but also reduce the flexibility and automation level of the production line. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a flipping tool for processing automotive sheet metal parts that can overcome the above problems or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a flipping fixture for processing automotive sheet metal parts includes a support frame, a flipping motor and a hydraulic pump. The surface of the support frame is fixedly connected to the surface of the flipping motor. The hydraulic pump is located at the lower end of the support frame. A clamping device is provided at the upper end of the support frame, and an auxiliary mechanism is provided on the clamping device.

[0006] The clamping device is used to clamp and fix plate-shaped parts;

[0007] The auxiliary mechanism is used to assist in the clamping process.

[0008] To improve operational flexibility, the clamping device preferably includes a dual-head motor, an adjusting screw, a transmission block, a mounting frame, a sliding block, a hydraulic cylinder, and a suction cup. The output end of the dual-head motor is fixedly connected to the front end of the adjusting screw. The surface of the adjusting screw is threadedly connected to the inner wall of the transmission block. The surface of the transmission block is fixedly connected to the two side surfaces of the mounting frame. The inner wall of the mounting frame is fixedly connected to the surface of the sliding block. The surface of the sliding block is fixedly connected to the lower end of the hydraulic cylinder. The upper end of the hydraulic cylinder is fixedly connected to the surface of the suction cup. The threads of the adjusting screws on both sides of the dual-head screw have opposite directions. This way, when the threads engage with the transmission block, the rotational motion can be effectively converted into linear motion, facilitating the control of the mounting frame's displacement.

[0009] To improve the adaptability of the device, preferably, the auxiliary mechanism includes a telescopic rod, a spring, a buffer block, and a travel groove. The surface of the telescopic rod is fitted with a spring, and the rear end of the telescopic rod is fixedly connected to the surface of the buffer block. The travel groove is opened at both ends of the mounting frame. The combination of the telescopic rod and the spring can provide good elastic reset capability. When subjected to external force, it can generate controllable compression deformation, and then restore the original state through the rebound force of the spring, thereby realizing the automatic reset function.

[0010] To improve the stability of the adjusting screw's operation, preferably, a fixed plate is provided on the surface of the support frame, the inner wall of the fixed plate is rotatably connected to the surface of the support frame, a bearing frame is provided on the surface of the support frame, the surface of the bearing frame is fixedly connected to the surface of the support frame, and bearing blocks are provided on both sides of the fixed plate, the surfaces of the bearing blocks are fixedly connected to the two side surfaces of the fixed plate. The bearing frame provides guidance and support for the rotation of the adjusting screw, effectively reducing frictional resistance during rotation and improving the flexibility and stability of the adjusting screw's operation.

[0011] To improve the stability of clamping adjustment, preferably, the surface of the dual-head motor is fixedly connected to the surface of the fixed plate, the rear end of the adjusting screw is rotatably connected to the inner wall of the bearing block, and the surface of the transmission block is slidably connected to the inner wall of the fixed plate through a sliding groove. The sliding groove between the transmission block and the fixed plate can guide the transmission block to move in a predetermined direction, ensuring the linearity and synchronicity when it drives the mounting frame to move.

[0012] To improve the safety of the device, preferably, the front end of the telescopic rod is fixedly connected to the inner wall of the mounting bracket, and the surface of the buffer block is slidably connected to the inner wall of the stroke groove. The stroke groove provides guidance for the displacement of the buffer block during the compression process, ensuring that it moves along a predetermined trajectory when compressing the telescopic rod and the spring, avoiding deviation, jamming, or uneven force, and realizing the rapid absorption and release of impact energy. This effectively reduces the mechanical collision force generated when the two mounting brackets approach or come into contact, protecting the key components of the equipment and the clamped workpiece from damage.

[0013] To improve the reliability of equipment operation, preferably, the inner wall of the bearing bracket is rotatably connected to the front surface of the adjusting screw, the output end of the flip motor is fixedly connected to the surface of the fixed plate, and the output end of the flip motor is rotatably connected to the inner wall of the support frame. While driving the fixed plate to rotate, the flip motor can still maintain the relative motion freedom between itself and the support frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a clamping device, an auxiliary mechanism, an adjusting screw, a transmission block, a mounting bracket, a suction cup, a telescopic rod, a spring, and a buffer block. The clamping device is used to clamp and fix plate-shaped parts, while the auxiliary mechanism assists in the clamping process. The threads on both sides of the double-ended screw have opposite directions, effectively converting rotational motion into linear motion when engaged with the transmission block, facilitating control of the mounting bracket's displacement. The combination of the telescopic rod and the spring provides excellent elastic reset capability, generating controllable compression deformation under external force and then restoring the original state through the spring's rebound force, thus achieving automatic reset. This invention solves the problem of lacking specialized tooling for processing automotive plate-shaped parts that can adapt to various sizes, provide stable clamping, and synchronous flipping. Existing devices are typically only suitable for parts of specific sizes and cannot meet the precise positioning and fixing requirements of parts of different specifications. Especially during angle adjustment or double-sided processing, traditional tooling flipping operations are slow and unstable, affecting processing efficiency and product quality. Frequent fixture changes also increase operational complexity and reduce the flexibility and automation level of the production line. Attached Figure Description

[0023] like Figures 1 to 4As shown in the figure, a flipping fixture for processing automotive sheet metal parts provided by this utility model embodiment includes a support frame 6, a flipping motor 7, and a hydraulic pump 8. The surface of the support frame 6 is fixedly connected to the surface of the flipping motor 7. The hydraulic pump 8 is located at the lower end of the support frame 6. A clamping device 1 is provided at the upper end of the support frame 6. An auxiliary mechanism 2 is provided on the clamping device 1. The clamping device 1 is used to clamp and fix the sheet metal parts, and the auxiliary mechanism 2 is used to assist the clamping process. The clamping device 1 includes a double-headed motor 101, an adjusting screw 102, a transmission block 103, a mounting bracket 104, a sliding block 105, a hydraulic cylinder 106, and a suction cup 107. The output end of the double-headed motor 101 is fixedly connected to the front end of the adjusting screw 102. The surface of the adjusting screw 102 is flush with the inner surface of the transmission block 103. The transmission block 103 is fixedly connected to the two side surfaces of the mounting bracket 104 via a threaded connection. The inner wall of the mounting bracket 104 is fixedly connected to the surface of the sliding block 105. The surface of the sliding block 105 is fixedly connected to the lower end of the hydraulic cylinder 106. The upper end of the hydraulic cylinder 106 is fixedly connected to the surface of the suction cup 107. The threads of the adjusting screws 102 on both sides of the double-ended screw have opposite directions. This way, when the screws engage with the transmission block 103, the rotational motion can be effectively converted into linear motion, facilitating the control of the displacement of the mounting bracket 104. The auxiliary mechanism 2 includes a telescopic rod 201, a spring 202, a buffer block 203, and a stroke groove 204. The spring 202 is sleeved on the surface of the telescopic rod 201. The rear end of the telescopic rod 201 is fixedly connected to the surface of the buffer block 203. The stroke groove 204... 04 is located at both ends of the mounting bracket 104. The combination of the telescopic rod 201 and the spring 202 provides good elastic reset capability. When subjected to external force, it can generate controllable compression deformation, and then return to its original state through the rebound force of the spring 202, thereby realizing the automatic reset function. A fixing plate 3 is provided on the surface of the support bracket 6. The inner wall of the fixing plate 3 is rotatably connected to the surface of the support bracket 6. A bearing bracket 4 is provided on the surface of the support bracket 6. The surface of the bearing bracket 4 is fixedly connected to the surface of the support bracket 6. Bearing blocks 5 are provided on both sides of the fixing plate 3. The surfaces of the bearing blocks 5 are fixedly connected to the two side surfaces of the fixing plate 3.

To ensure stability and smooth operation, the surface of the dual-head motor 101 is fixedly connected to the surface of the fixed plate 3. The rear end of the adjusting screw 102 is rotatably connected to the inner wall of the bearing block 5. The surface of the transmission block 103 is slidably connected to the inner wall of the fixed plate 3 via a sliding groove.

The front end of the telescopic rod 201 is fixedly connected to the inner wall of the mounting frame 104. The surface of the buffer block 203 is slidably connected to the inner wall of the stroke groove 204.

The inner wall of the bearing bracket 4 is rotatably connected to the front surface of the adjusting screw 102. The output end of the tilting motor 7 is fixedly connected to the surface of the fixed plate 3, and the output end of the tilting motor 7 is rotatably connected to the inner wall of the support frame 6. While driving the fixed plate 3 to rotate, the tilting motor 7 can still maintain relative freedom of movement with the support frame 6.

[0024] The working principle of this utility model:

[0025] When processing sheet metal parts for automobiles, the sheet metal part to be processed is first placed between two mounting brackets 104 and positioned on the suction cups 107 on the mounting brackets 104. Then, according to the actual size of the sheet metal part, the distance between the two suction cups 107 is adjusted to ensure clamping stability and adaptability. This adjustment process is achieved by activating a dual-head motor 101 fixed on the support frame 6. The dual-head motor 101 has adjusting screws 102 connected to its two output ends. When the motor is running, the two adjusting screws 102... 02 can rotate synchronously. The surface of the mounting bracket 104 is provided with transmission blocks 103. These transmission blocks 103 cooperate with the sliding grooves on the fixed plate 3. When the dual-head motor 101 drives the adjusting screw 102 to rotate, the transmission blocks 103 will move along the direction of the sliding groove within the mounting bracket 104, thereby driving the two mounting brackets 104 to move in opposite directions. This causes the suction cups 107 within the mounting bracket 104 to expand or retract to both sides, achieving adjustment of the spacing between the suction cups 107. After the position of the suction cups 107 is adjusted, the hydraulic pump 8 controls... The hydraulic cylinder 106 performs a telescopic operation. The telescopic rod 201 of the hydraulic cylinder 106 pushes the suction cup 107 to gradually approach and adhere to the surface of the plate-shaped part, thereby achieving a stable clamping of parts of different sizes. After the clamping is completed and confirmed to be correct, the flipping motor 7 on the support frame 6 is started. The flipping motor 7 drives the fixed plate 3 to rotate through its output shaft. The fixed plate 3 is connected to the entire mounting frame 104, so it can drive the mounting frame 104 and the plate-shaped parts clamped inside to flip together. This process allows the plate-shaped parts to complete the angle conversion without changing the clamping state, which is convenient for subsequent processing. Auxiliary mechanisms 2 are provided at both ends of the mounting frame 104. When the two mounting frames 104 approach or come into contact during the movement, the buffer block 203 in the stroke groove 204 opened at both ends of the mounting frame 104 will be subjected to a squeezing force, thereby compressing the built-in telescopic rod 201 and spring 202. This buffer structure can effectively absorb the impact energy generated by the collision and reduce the rigid impact between mechanical structures, thereby protecting the equipment and the workpiece.

[0026] The specific models and specifications of the flipping motor 7, hydraulic pump 8, dual-head motor 101, adjusting screw 102, hydraulic cylinder 106, suction cup 107, telescopic rod 201, spring 202 and bearing bracket 4 proposed in this application need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0027] The wiring connection methods and control methods of the flipping motor 7, hydraulic pump 8 and dual-head motor 101 proposed in this application are all prior art in this field, and therefore will not be described in detail.
