Description
Technical Field
[0001] The present invention relates to the technical field of welding pressing, and particularly relates to a novel composite pressing mechanism. Background Art
[0002] A composite pressing mechanism is a mechanical device that realizes efficient, stable, and precise pressing functions by combining multiple pressing principles or structural forms. Its core lies in optimizing the distribution, direction, and adjustment method of the pressing force through multi-stage force transmission (such as levers, wedges, gear racks, etc.), multi-force source combination (such as hydraulic + mechanical, pneumatic + electric), or structural compounding (such as floating pressing + centering clamping), transforming the limitations of a single pressing method into advantages to meet the requirements of complex working conditions.
[0003] Due to the complexity of the workpiece size and shape, the existing composite pressing mechanisms usually can only be targeted at certain specific workpieces, which requires the factory to frequently replace the mechanisms during the actual production process to achieve the pressing purpose of different workpieces. Such a method not only consumes a great deal of manpower and material resources but also reduces the production efficiency of the workpieces and increases the production cost.

A third hydraulic cylinder is fixedly assembled on one side surface of the rotating sleeve block, a rotator is arranged at the piston end of the third hydraulic cylinder, and an external gripper is arranged at the other end of the rotator.
[0006] Further, as a preference, the fixed position adjustment mechanism includes: A fixed platform is fixedly assembled on the fixed bearing plate in the middle of the external fixing assembly. A rotating disk is fixedly assembled on the upper surface of the fixed platform, and a driving motor is arranged between the rotating disk and the fixed platform; The fixed support frame is horizontally and fixedly assembled on the upper surface of the rotating disk. Both sides of the upper end of the fixed support frame are fixedly assembled with first bearing seats, and a flipping and fixing platform is rotatably arranged between the two first bearing seats. There are two driving brackets, which are mirror - set and fixedly assembled on the upper surface of the middle part of the fixed support frame, and both driving brackets are embedded in the flipping and fixing platform.
[0007] Furthermore, as a preference, the flipping and fixing platform includes: A fixed plate, on the lower surface of which two second bearing seats are fixedly assembled, so that the fixed plate is rotatably arranged between the two first bearing seats. A regular octagonal notch is formed in the middle of the fixed plate, and an octagonal embedding frame is arranged at this notch. Two opposite sides of the octagonal embedding frame are parallel to the second bearing seats. There are two flipping drive grooves, which are mirror - set and respectively fixedly assembled on the fixed plate between the two second bearing seats and the outer side surface of the octagonal embedding frame, and the flipping drive grooves are embedded in the driving brackets.
[0008] Furthermore, as a preference, a first hydraulic cylinder is rotatably arranged at the center of each side of the octagonal embedding frame, and a flexible gripper is fixedly assembled at the piston end of the first hydraulic cylinder. A rotating driver is sleeved at the front end of the cylinder body of the first hydraulic cylinder, and the rotating driver is fixedly assembled on the outside of the side surface of the octagonal embedding frame where the first hydraulic cylinder is located.
[0009] Furthermore, as a preference, at the other four included angles except for the included angles formed by the two opposite sides of the octagonal embedding frame parallel to the second bearing seats and the other sides, vertical grippers are fixedly embedded, and a second hydraulic cylinder is arranged between the rotating connecting rods at the clamping ends of the vertical grippers.
[0010] Furthermore, as a preference, elastic rubber blocks are arranged at the positions where the flexible grippers and the vertical grippers contact the workpiece, and a pressure sensing module is arranged in each elastic rubber block.
[0011] Furthermore, as a preference, sliding sleeves are arranged at the joints of the sliding beam and the vertical track frame, enabling the sliding beam to slide along its axial direction.
[0012] Compared with the prior art, the present invention provides a novel composite pressing mechanism, which has the following beneficial effects: In the present invention, four pressing systems are provided, including a first pressing system mainly composed of eight flexible grippers on a fixed position adjusting mechanism, a second pressing system mainly composed of four vertical grippers on the fixed position adjusting mechanism, a third clamping system mainly composed of an internal support assembly, and a fourth pressing system mainly composed of an external fixing assembly.

[0014] In the present invention, the three self-driving sliders on the fixed track of the external fixing assembly can slide freely on the fixed track, and the sliding range of each self-driving slider is the track range between the extreme position and the adjacent self-driving slider (or the track range between two adjacent self-driving sliders). Due to the complexity of the shape and size of the first workpiece, the number and positions of the clampable positions on the outside of the first workpiece are not fixed. After the first workpiece is initially fixed, the three self-driving sliders will selectively clamp the clampable positions on the first workpiece. And when selecting positions, the three self-driving sliders should be as dispersed as possible to achieve the best fixing effect. At the same time, when clamping at the selected position, the external gripper can be adjusted in angle through the rotator and the rotating sleeve block, and the position can be adjusted through the vertical sliding frame and the third hydraulic cylinder, so that the external gripper can smoothly clamp the clampable position of the first workpiece, and then better perform other operations.

Specific implementation mode
[0016] Please refer to Figures 1 to 5 , the present invention provides a new type of composite pressing mechanism, including a fixed bearing plate 1 and an internal support component 5 and a second workpiece tightener 6 fixed thereon. It is characterized in that an external fixing component 4 is fixedly assembled on the fixed bearing plate 1, the external fixing component 4 is arranged on one side of the internal support component 5 and the second workpiece tightener 6, and a fixed adjustment mechanism 2 is fixedly assembled on the fixed bearing plate 1 in the middle of the external fixing component 4; The external fixing component 4 includes a fixed track 41, the fixed track 41 is fixedly assembled on the upper surface of the fixed bearing plate 1 on one side of the internal support component 5 and the second workpiece tightener 6, three self-driving sliders 42 are slidably arranged on the fixed track 41, and a vertical track frame 43 is fixedly assembled on the upper surface of each self-driving slider 42, and a sliding beam 44 is slidably arranged on the vertical track frame 43; A rotating sleeve block 45 is rotatably sleeved on the sliding beam 44, and the sliding beam 44 is provided with a driving group for the rotating sleeve block 45. A third hydraulic cylinder 46 is fixedly assembled on one side surface of the rotating sleeve block 45, a rotator 48 is arranged at the piston end of the third hydraulic cylinder 46, and an external gripper 47 is arranged at the other end of the rotator 48; As a preferred embodiment, first, the first workpiece 3 (the main workpiece to be clamped) is adjusted to an appropriate angle (so that the position where welding or other operations need to be performed stays at a non-clamping position) and placed on the fixed positioning mechanism 2. The fixed positioning mechanism 2 will firmly clamp the first workpiece 3. Then, the fixed positioning mechanism 2 will adjust the position and angle of the first workpiece 3 by rotation, so that the position where welding or other operations need to be performed can be adjusted below the internal support assembly 5. The internal support assembly 5 will support the first workpiece 3 from the inside, so as to further press the first workpiece 3. Then, the second workpiece applicator 6 will send the second workpiece (sub-workpiece) that needs to be welded or other operations to the position on the first workpiece 3 that needs to be operated. Then, the external fixing assembly 4 will adjust its position and select a suitable position and angle to further clamp the first workpiece 3, so as to enhance the pressing effect of the device. Thus, the pressing work of the workpiece is completed. And after the operation (welding or other operations) at this position of the first workpiece 3 is completed, the external fixing assembly 4 will release the first workpiece 3, and rotate the first workpiece 3 through the fixed positioning mechanism 2 to adjust other positions to be operated to this position (for the case where there are more than one position to be operated on the first workpiece 3). The internal support assembly 5 will support the first workpiece 3 from the inside, so as to further press the first workpiece 3. Then, the second workpiece applicator 6 will send the second workpiece (sub-workpiece) that needs to be welded or other operations to the position on the first workpiece 3 that needs to be operated. Then, the external fixing assembly 4 will adjust its position and select a suitable position and angle to further clamp the first workpiece 3. Repeat the operation until all the positions to be operated on the first workpiece 3 are completed, and the pressing work of the entire workpiece is completed; As a preferred embodiment, the three self-driven sliders 42 on the fixed track 41 can slide freely on the fixed track 41, and the sliding range of each self-driven slider 42 is the track range between the extreme position and the adjacent self-driven slider 42 (or the track range between two adjacent self-driven sliders 42). Due to the complexity of the shape and size of the first workpiece 3, the number and positions of the clampable positions on the outside of the first workpiece 3 are not fixed. After the first workpiece 3 is initially fixed, the three self-driven sliders 42 will selectively clamp the clampable positions on the first workpiece 3 (which can be confirmed by scanning in the early stage). And when selecting positions, the three self-driven sliders 42 should be as dispersed as possible, so as to achieve the best fixing effect. At the same time, when clamping at the selected position, the external gripper 47 can adjust its angle through the rotator 48 and the rotating sleeve block 45, and adjust its position through the vertical track frame 43 and the third hydraulic cylinder 46, so that the external gripper 47 can smoothly clamp the clampable position of the first workpiece 3, and then better perform other operations.
[0017] Further, the fixed positioning mechanism 2 includes: Fixed platform 21, fixed bearing plate 1 fixedly assembled in the middle of the external fixing component 4, a rotating disk 22 fixedly assembled on the upper surface of the fixed platform 21, and a driving motor 23 is arranged between the rotating disk 22 and the fixed platform 21; Fixed support frame 24, horizontally fixedly assembled on the upper surface of the rotating disk 22, both sides of the upper end of the fixed support frame 24 are fixedly assembled with first bearing seats 25, and a flipping fixed platform 26 is rotatably arranged between the two first bearing seats 25; Driving brackets 27, two are arranged in a mirror image, both are fixedly assembled on the upper surface of the middle part of the fixed support frame 24, and the two driving brackets 27 are both embedded in the flipping fixed platform 26; As a preferred embodiment, the driving motor 23 can drive the rotating disk 22 to drive the components thereon and the first workpiece 3 to rotate, so that the position to be operated of the first workpiece 3 can be exposed at the position where the internal support component 5 and the second workpiece closer 6 can operate, and after the operation of this position on the first workpiece 3 is completed, it can be rotated to adjust other positions to this position (in the case where there are more than one position to be operated on the first workpiece 3), thus greatly shortening the working time and improving the production efficiency. The driving bracket 27 can drive the flipping fixed platform 26 to drive the first workpiece 3 thereon to flip, so as to further adjust the position to be operated of the first workpiece 3, improve the practicability of the device, save production costs and production efficiency.
[0018] Furthermore, the flipping fixed platform 26 includes: Fixed plate 261, two second bearing seats 262 are fixedly assembled on its lower surface, so that the fixed plate 261 is rotatably arranged between the two first bearing seats 25. A regular octagonal notch is opened in the middle of the fixed plate 261, and an octagonal embedding frame 264 is arranged at this notch, and two opposite sides of the octagonal embedding frame 264 are parallel to the second bearing seats 262; Flipping drive grooves 263, two are arranged in a mirror image, respectively fixedly assembled on the fixed plate 261 between the two second bearing seats 262 and the outer side surface of the octagonal embedding frame 264, and the flipping drive grooves 263 are embedded in the driving brackets 27.
[0019] Furthermore, a first hydraulic cylinder 265 is rotatably arranged at the center of each side of the octagonal embedding frame 264, and a flexible gripper 266 is fixedly assembled at the piston end of the first hydraulic cylinder 265; A rotating driver 267 is sleeved at the front end of the cylinder body of the first hydraulic cylinder 265, and the rotating driver 267 is fixedly assembled on the outside of the side surface of the octagonal embedding frame 264 where the first hydraulic cylinder 265 is located; As a preferred embodiment, in actual operation, the eight first hydraulic cylinders 265 can all independently extend or contract. The extension of the first hydraulic cylinder 265 will cause the flexible gripper 266 to fit with the first workpiece 3, so as to achieve the purpose of gripping the first workpiece 3. And due to the complexity of the shape and size of the first workpiece 3, during the actual gripping process, the rotation driver 267 will drive the first hydraulic cylinder 265 to drive the flexible gripper 266 to rotate, so that the flexible gripper 266 can adjust the angle when facing different workpiece conditions, and then achieve a better gripping and fixing effect.
[0020] Furthermore, at the other four included angles except for the included angles formed by the two opposite side surfaces of the octagonal mounting frame 264 parallel to the second bearing seat 262 and the other side surfaces, vertical grippers 268 are fixedly installed, and a second hydraulic cylinder 269 is arranged between the rotating connecting rods at the clamping ends of the vertical grippers 268; As a preferred embodiment, the eight flexible grippers 266 are the first pressing system. However, in the face of the possible complex conditions (shape and size) of the first workpiece 3, the four vertical grippers 268 can be used as the second clamping system to further clamp and fix the first workpiece 3. At the same time, the setting of the second hydraulic cylinder 269 can further adjust the position where the clamping points of the vertical grippers 268 are located according to the actual situation of the first workpiece 3, so as to achieve a better pressing effect.
[0021] Furthermore, elastic rubber blocks are arranged at the positions where the flexible grippers 266 and the vertical grippers 268 contact the workpiece, and a pressure sensing module is arranged in each elastic rubber block; As a preferred embodiment, due to the irregular shape and size of the first workpiece 3, the driving strengths of each flexible gripper 266 and each vertical gripper 268 are different. If the driving strength is too large, it will cause damage to the first workpiece 3, and if the driving strength is too small, the pressing effect of the first workpiece 3 will be unstable. Therefore, elastic rubber blocks with pressure sensing modules are set. After the flexible grippers 266 and the vertical grippers 268 contact the first workpiece 3 and are further driven, the elastic rubber blocks will be compressed. When the pressure sensing module reaches the set pressure, the corresponding flexible gripper 266 and vertical gripper 268 will stop, so that the fixed positioning mechanism 2 can achieve a better pressing effect.
[0022] Furthermore, sliding sleeves are arranged at the joints of the sliding beam 44 and the vertical track frame 43, which can enable the sliding beam 44 to slide along its axial direction. This sliding can further increase the clamping range of the external gripper 47, so as to ensure the effect of external fixation.
[0023] In specific implementation, the following steps are included: First, the first workpiece 3 is placed on the fixed positioning mechanism 2 after adjusting the angle. The fixed positioning mechanism 2 will firmly clamp the first workpiece 3. Then, the fixed positioning mechanism 2 will adjust the position and angle of the first workpiece 3 by rotation, so that the position where welding or other operations need to be performed can be adjusted below the internal support component 5. The internal support component 5 will support the first workpiece 3 from the inside, so as to further press the first workpiece 3. Then, the second workpiece applicator 6 will send the second workpiece that needs to be welded or perform other operations to the position on the first workpiece 3 where the operation needs to be performed. Then, the external fixing component 4 will adjust the position and select a suitable position and angle to further clamp the first workpiece 3, so as to enhance the pressing effect of the device. Thus, the pressing work of the workpiece is completed. And after the operation at this position of the first workpiece 3 is completed, the external fixing component 4 will release the first workpiece 3, and rotate the first workpiece 3 through the fixed positioning mechanism 2 to adjust other positions to be operated to this position (in the case where there are more than one position to be operated on the first workpiece 3). The internal support component 5 will support the first workpiece 3 from the inside, so as to further press the first workpiece 3. Then, the second workpiece applicator 6 will send the second workpiece that needs to be welded or perform other operations to the position on the first workpiece 3 where the operation needs to be performed. Then, the external fixing component 4 will adjust the position and select a suitable position and angle to further clamp the first workpiece 3. Repeat the operation until all the positions to be operated on the first workpiece 3 are completed, and the pressing work of the whole workpiece is completed.
