Description

Technical Field

[0001] This utility model relates to the field of automotive radiator assembly equipment, specifically to a crimping device for automotive radiator water chamber crimping equipment. Background Technology

[0002] The car radiator is the core component of the car's cooling system. Its function is to dissipate the excess heat carried by the coolant circulating in the engine into the air, thereby keeping the engine at an optimal operating temperature and preventing the engine from overheating and causing damage.

[0003] Existing automotive radiators include a core, with end plates at the top and bottom. Side walls surround the end plates, and recesses are formed inside the side walls for installing sealing rings and water chambers. Claws are provided around the side walls. During assembly, the sealing rings and water chambers are first pressed into the recesses in sequence, and then the claws are pressed against the inside of the side walls to fix the water chambers.

[0004] When a crimping device crimps the teeth, it involves two actions: "crimping" and "pressing." "Crimping" involves bending the originally upright teeth inward, while "pressing" involves squeezing the bent teeth downward. Traditional crimping devices often use two drive sources to complete the "crimping" and "pressing" actions separately. On the one hand, "pressing" can only be performed after "crimping" is completely completed, resulting in a gap between the actions and reduced assembly efficiency. On the other hand, two independent drive sources make the device structure more cumbersome. In addition, when the device needs to be changed to accommodate a new specification radiator, the device structure needs to be manually adjusted. During the adjustment process, multiple points need to be adjusted simultaneously. Since the precision of manual adjustment is limited, multiple adjustments are required, making the changeover process time-consuming, labor-intensive, and inefficient. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a crimping device for a car radiator water chamber crimping equipment with a simple structure and high assembly efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a clamping worktable, wherein the clamping worktable is longitudinally provided with a core clamping slide for longitudinal sliding of the core body; long-side clamping seats are respectively provided on both sides of the core clamping slide on the clamping worktable; each long-side clamping seat is provided with a plurality of long-side clamping mechanisms arranged sequentially along the longitudinal direction; the long-side clamping mechanism includes a long-side clamping arm, a long-side transmission rod, a long-side transmission track, a long-side transmission short rod, a long-side drive rod, and a long-side drive assembly; the long-side clamping arm is arranged laterally; the end of the long-side clamping arm facing the core clamping slide serves as the long-side clamping end of the clamping claw teeth, and the end facing away from the core clamping slide serves as the long side. At the force-bearing end, the long-side transmission rod is arranged laterally and located below the long-side clamping arm. Above the end of the long-side transmission rod facing the core clamping slide, there is a long-side transmission hinge seat that is hinged to the long-side clamping arm. The long-side transmission track is fixed laterally to the long-side clamping seat and slides laterally with the long-side transmission rod. The long-side drive rod is arranged vertically and located on the other side of the long-side transmission rod opposite to the core clamping slide. The long-side drive assembly is located below the long-side drive rod and drives the long-side drive rod to move vertically. The long-side transmission short rod is arranged laterally, with one end hinged to the long-side transmission rod and the other end hinged to the upper end of the long-side drive rod. Above the long-side transmission short rod, there is a force-applying protrusion that squeezes the force-bearing end of the long side when it rises.

[0007] By adopting the above technical solution, when the core reaches the core clamping slide, the long-side drive assembly drives the long-side drive rod to rise. As the long-side drive rod rises, the long-side transmission rod drives the long-side clamping arm to gradually approach the core clamping slide laterally. The long-side clamping end bends the claw teeth towards the water chamber. Then, the long-side drive rod continues to rise, and the force-applying protrusion of the long-side transmission rod squeezes the long-side force-bearing end, causing the long-side force-bearing end to rise while the long-side clamping end presses down, squeezing the claw teeth downward, thus completing the automatic clamping of the long-side clamping arm. The above structure has the following advantages: a single drive source drives the long-side drive rod to rise linearly, achieving continuous clamping action of the long-side clamping end on the claw teeth, avoiding the assembly interval caused by dual drive sources, greatly improving assembly efficiency and product quality. At the same time, it simplifies the drive structure, making the equipment structure more streamlined.

[0008] The present invention is further configured such that: each of the aforementioned long-side clamping seats is provided with two sets of long-side driving components, each long-side driving component including a long-side driving seat and a long-side driving motor; a driving base plate is fixedly provided below the long-side clamping seat; the driving base plate is provided with long-side driving rails for vertical sliding of each long-side driving seat; each of the aforementioned long-side driving seats is provided with a long-side driving nut seat; the long-side driving motor is fixed to the driving base plate and is provided with a long-side driving screw that is threadedly engaged with the long-side driving nut seat in the same set along the vertical direction; and the long-side driving rods located on the same side in the transverse direction are fixed at intervals to the two long-side driving seats.

[0009] By adopting the above technical solution, two sets of long-side drive components, each consisting of a long-side drive seat and a long-side drive motor, drive the long-side drive rods on the same side at intervals. This avoids excessive force on the long-side drive seat and deformation caused by all long-side drive rods being driven by the same long-side drive seat, thereby improving the reliability of equipment operation.

[0010] The present invention is further configured as follows: the core clamping slide includes clamping slide strips located on both sides in the lateral direction, each clamping slide strip being fixed to the long side clamping seat on the same side; the clamping worktable is provided with a core clamping mechanism on one side of the core clamping slide; the core clamping mechanism includes a core clamping track, a core clamping cylinder, a core clamping transmission rod, and a core clamping drive rod; the core clamping track is arranged in the lateral direction and slides laterally with the long side clamping seat; the core clamping drive rod is arranged in the vertical direction; the core clamping cylinder is located below the core clamping drive rod and drives the core clamping drive rod to move vertically; the core clamping transmission rod is arranged in the lateral direction, with one end hinged to the long side clamping seat and the other end hinged to the upper end of the core clamping drive rod.

[0011] By adopting the above technical solution, the core clamping cylinder drives the clamping drive rod to move upward, thereby driving the long side clamping seat to move laterally closer to the core clamping slide. Since the clamping slide strip is fixed to the long side clamping seat, the core located in the core clamping slide is locked between the clamping slide strips on both sides during clamping, ensuring stable clamping.

[0012] The present invention is further configured such that: the pressing worktable is laterally slidably provided with a long-side changing slide for mounting a core clamping cylinder; the pressing worktable is fixedly provided with a first long-side changing fixing seat on the other side of the long-side changing slide relative to the core pressing slide; a first long-side quick changing block is provided between the long-side changing slide and the first long-side changing fixing seat; and a first core quick changing cylinder is fixedly provided on the first long-side changing fixing seat to drive the long-side changing slide to slide laterally and clamp the first long-side quick changing block between the long-side changing slide and the first long-side changing fixing seat.

[0013] By adopting the above technical solution, the first core quick-change cylinder can be activated to quickly replace the first long side quick-change block of different thicknesses, thereby adjusting the distance between the long side change slide and the core clamping slide, and then adjusting the distance between the long side clamping seats on both sides, that is, adjusting the distance between the clamping slide strips fixed to the long side clamping seats, so as to adapt to cores of different thicknesses, realize the quick and accurate change of the clamping device, and greatly improve the change efficiency.

[0014] The present invention is further configured such that: the pressing workbench is provided with a long side changing track on the other side of the core pressing slide relative to the core clamping mechanism; the long side changing track is arranged laterally and slides laterally with the long side pressing seat; a second long side changing fixing seat is fixedly provided on the other side of the pressing workbench relative to the core pressing slide; a second long side quick changing block is provided between the second long side changing fixing seat and the long side pressing seat; and a second core quick changing cylinder is fixedly provided on the second long side changing fixing seat to drive the long side pressing seat to slide laterally and clamp the second long side quick changing block between the long side pressing seat and the second long side changing fixing seat.

[0015] By adopting the above technical solution, the second core quick-change cylinder can be activated to quickly replace the second long side quick-change block of different thicknesses, thereby adjusting the distance between the long side clamping seats on both sides, that is, adjusting the distance between the clamping slide strips fixed to the long side clamping seats, and thus adapting to cores of different thicknesses, realizing the quick and accurate change of the clamping device, and greatly improving the change efficiency.

[0016] The present invention is further configured to include a core preparation slide located in front of the core pressing slide and for longitudinal sliding of the core. The core preparation slide includes preparation slide strips located on both sides in the lateral direction. The pressing worktable is provided with preparation change rails for lateral sliding of each preparation slide strip. A synchronous change arm is provided between the preparation slide strip and the pressing seat on the same side to fix the two.

[0017] By adopting the above technical solution, the core preparation slide is used to place the core waiting to be snapped. The synchronous changing arm fixes the preparation slide strip to the same side long side snapping seat. When the long side snapping seat is changed, the preparation slide strip is changed synchronously, which simplifies the changing steps and changing structure and greatly improves the changing efficiency.

[0018] This utility model is further configured to include: short-side clamping seats located on both longitudinal sides of the core clamping slide and a short-side clamping mechanism disposed on the short-side clamping seats. The short-side clamping mechanism includes a short-side clamping arm, a short-side transmission rod, a short-side transmission guide groove, a short-side transmission rod, a short-side drive rod, and a short-side drive cylinder. The short-side clamping arm is arranged longitudinally, with the end of the short-side clamping arm facing the core clamping slide serving as the short-side clamping end of the clamping claw teeth, and the end facing away from the core clamping slide serving as the short-side force-bearing end. The short-side transmission rod is arranged longitudinally and located below the short-side clamping arm. A short-side transmission hinge seat is provided above the end of the moving long rod facing the core clamping slide, which is hinged to the short-side clamping arm. The short-side transmission guide groove is arranged longitudinally on the short-side clamping seat and slides longitudinally with the short-side transmission long rod. The short-side drive rod is arranged vertically and located on the other side of the short-side transmission long rod opposite to the core clamping slide. The short-side drive cylinder is fixed to the short-side clamping seat and drives the short-side drive rod to move vertically. The short-side transmission rod is arranged longitudinally, with one end hinged to the short-side transmission long rod and the other end hinged to the upper end of the short-side drive rod. When the short-side drive rod rises, the upper end presses against the short-side force-bearing end.

[0019] By adopting the above technical solution, when the core reaches the core clamping slide, the short-side drive cylinder drives the short-side drive rod to rise. As the short-side drive rod rises, the short-side transmission rod drives the short-side clamping arm to gradually approach the core clamping slide along the longitudinal direction. The short-side clamping end bends the claw teeth towards the water chamber. Then, the short-side drive rod continues to rise, and the upper end of the short-side drive rod presses against the short-side force-bearing end, causing the short-side force-bearing end to rise while the short-side clamping end presses down, pressing the claw teeth downward, thus completing the automatic clamping of the short-side clamping arm. The above structure has the following advantages: a single drive source drives the short-side drive rod to rise linearly, achieving continuous clamping action of the short-side clamping end against the claw teeth, avoiding the assembly interval caused by dual drive sources, greatly improving assembly efficiency and product quality. At the same time, it simplifies the drive structure, making the equipment structure more streamlined.

[0020] This utility model is further configured to include a short-side longitudinal moving seat, a short-side longitudinal moving track, a short-side longitudinal moving motor, a short-side transverse moving track, and a short-side transverse moving cylinder. The short-side longitudinal moving track is fixed longitudinally to the short-side longitudinal moving seat and slides longitudinally with the short-side clamping seat. The short-side clamping seat is provided with a short-side longitudinal moving nut seat. The short-side longitudinal moving motor is fixed to the short-side longitudinal moving seat and drives the short-side longitudinal moving screw, which is threadedly engaged with the short-side longitudinal moving nut seat, longitudinally. The short-side transverse moving track is fixed transversely to the clamping worktable and slides transversely with the short-side longitudinal moving seat. The short-side transverse moving cylinder is fixed to the clamping worktable and drives the short-side longitudinal moving seat to slide transversely.

[0021] By adopting the above technical solution, the short side longitudinal movement mechanism is automatically moved longitudinally by the cooperation of the short side longitudinal movement track and the short side longitudinal movement motor, and the short side transverse movement mechanism is automatically moved laterally by the cooperation of the short side transverse movement track and the short side transverse movement cylinder. This allows the short side crimping mechanism to automatically exit the core crimping slide when not being processed, and automatically enter the core crimping slide when processing. This avoids obstructing the core pushing while achieving automatic crimping of the short side, making the equipment operation smoother.

[0022] This utility model is further configured to include: a core transition slide, a transition slide strip transverse shift seat, a transition slide strip transverse track, and a transition slide strip transverse shift cylinder. The transition slide strip transverse track is fixed laterally to the pressing worktable and located on the other side of the core pressing slide opposite to the short side longitudinal shift seat. The transition slide strip transverse shift seat and the transition slide strip transverse track slide laterally in cooperation. The transition slide strip transverse shift cylinder is fixed to the long side pressing seat and drives the transition slide strip transverse shift seat to slide laterally. The core transition slide is located on both longitudinal sides of the core pressing slide and allows the core to slide longitudinally. The core transition slide includes core transition slide strips located on both sides laterally, with one side of the core transition slide strip fixed to the short side longitudinal shift seat and the other side of the core transition slide strip fixed to the transition slide strip transverse shift seat.

[0023] By adopting the above technical solution, the core transition slide is used to transition the core from the previous station to the core pressing slide or from the core pressing slide to the next station. The lateral movement of the core transition slide is controlled by the short side longitudinal moving seat and the transition slide bar transverse moving seat, which prevents the core transition slide from obstructing the short side pressing mechanism from entering the core pressing slide. In addition, the short side longitudinal moving seat utilizes its lateral movement function, and the transition slide bar transverse moving seat utilizes the shape-changing function of the long side pressing seat to realize the automatic shape-changing of the core transition slide, simplifying the shape-changing steps and structure, and greatly improving the shape-changing efficiency.

[0024] This utility model is further configured to include a water chamber pressing mechanism, which includes a water chamber pressing platform located above the pressing workbench. Below the water chamber pressing platform is a tooling mounting base for installing water chamber contouring fixtures. The water chamber pressing platform is equipped with multiple lifting guide sleeves, two lifting nuts, and a water chamber pressing motor. The tooling mounting base is vertically equipped with lifting guide rods that slide and cooperate with each lifting guide sleeve. The two lifting nuts are rotatably mounted on both longitudinal sides of the water chamber pressing platform. Each lifting nut is coaxially fixed with a lifting synchronous wheel. The tooling mounting base is vertically equipped with lifting screws that thread-fit each lifting nut. The water chamber pressing motor drives a pressing synchronous wheel that rotates synchronously with each lifting synchronous wheel via a synchronous belt.

[0025] By adopting the above technical solution, the water chamber pressing motor drives each lifting synchronous wheel to rotate synchronously through the pressing synchronous wheel and the synchronous belt, thereby realizing the dual-point lifting structure of the tooling mounting base. This makes the lifting of the water chamber contour tooling installed on the tooling mounting base more precise and stable. It can also adapt to water chambers of different heights by adjusting the lifting height, and adopts an automatic adjustment structure to achieve digital rapid model change.

[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] like Figure 1 , 2As shown in Figure 3, this utility model discloses a crimping device for a car radiator water chamber crimping equipment, including a crimping worktable 1. The crimping worktable 1 is longitudinally provided with a core crimping slide 3 for longitudinal sliding of the core. Long side crimping seats 2 are respectively provided on both sides of the core crimping slide 3 on the crimping worktable 1. Each long side crimping seat 2 is provided with multiple long side crimping mechanisms arranged longitudinally. The long side crimping mechanism includes a long side crimping arm 21, a long side transmission rod 22, a long side transmission track 23, a long side transmission short rod 24, and a long side... The drive rod 25 and the long-side drive assembly, the long-side clamping arm 21 are arranged laterally, the end of the long-side clamping arm 21 facing the core clamping slide 3 serves as the long-side clamping end 211 of the clamping claw teeth, and the end facing away from the core clamping slide 3 serves as the long-side force-bearing end 212. The long-side drive rod 22 is arranged laterally and located below the long-side clamping arm 21. Above the end of the long-side drive rod 22 facing the core clamping slide 3, a long-side drive hinge seat 221 is provided, which is hinged to the long-side clamping arm 21. The long-side drive rail 23 is fixed laterally to the long-side clamping seat 211. The long-side drive rod 25 is vertically positioned and located on the opposite side of the long-side drive rod 22 from the core clamping slide 3. The long-side drive assembly is located below the long-side drive rod 25 and drives the long-side drive rod 25 to move vertically. The long-side drive short rod 24 is horizontally positioned, with one end hinged to the long-side drive rod 22 and the other end hinged to the upper end of the long-side drive rod 25. A force-applying protrusion 241 is provided above the long-side drive short rod 24 to compress the long-side force-bearing end 212 when it rises. When the core reaches the core clamping slide 3... The long-side drive assembly drives the long-side drive rod 25 upward. As the long-side drive rod 25 rises, the long-side transmission rod 22 drives the long-side clamping arm 21 to gradually approach the core clamping slide 3 laterally. The long-side clamping end 211 bends the claw teeth towards the water chamber. Then, the long-side drive rod 25 continues to rise, and the force-applying protrusion 241 of the long-side transmission rod 24 squeezes the long-side force-receiving end 212, causing the long-side force-receiving end 212 to rise while the long-side clamping end 211 presses down. The long-side clamping end 211 presses the claw teeth downward, completing the automatic clamping of the long-side clamping arm 21. The above structure has the following advantages: the long-side drive rod 25 is driven to rise linearly by a single drive source, which can realize the continuous clamping action of the long-side clamping end 211 on the claw teeth, avoiding the assembly interval caused by dual drive sources, greatly improving assembly efficiency and product quality. At the same time, it simplifies the drive structure, making the equipment structure more streamlined.

[0030] like Figure 2 , 3As shown, each long-side clamping seat 2 is provided with two sets of long-side drive assemblies. The long-side drive assembly includes a long-side drive seat 26 and a long-side drive motor 27. A drive base plate 29 is fixedly provided below the long-side clamping seat. The drive base plate 29 is provided with long-side drive rails 28 for vertical sliding of each long-side drive seat 26. Each long-side drive seat 26 is provided with a long-side drive nut seat 261. The long-side drive motor 27 is fixed to the drive base plate 29 and is provided with a long-side drive screw 271 that is threadedly engaged with the long-side drive nut seat 261 in the same group. The long-side drive rods 25 located on the same side in the transverse direction are fixed at intervals to the two long-side drive seats 26. The two sets of long-side drive assemblies composed of long-side drive seats 26 and long-side drive motors 27 drive the long-side drive rods 25 on the same side at intervals, avoiding excessive force and deformation of the long-side drive seat 26 after all the long-side drive rods 25 are driven by the same long-side drive seat 26, thereby improving the reliability of equipment operation.

[0031] like Figure 2 , 3 As shown in Figures 4 and 5, the core clamping slide 3 includes clamping slide strips 31 located on both sides of the transverse direction. Each clamping slide strip 31 is fixed to the long side clamping seat 2 on the same side. The clamping worktable 1 is provided with a core clamping mechanism on one side of the core clamping slide 3. The core clamping mechanism includes a core clamping track 4, a core clamping cylinder 41, a core clamping transmission rod 42, and a core clamping drive rod 43. The core clamping track 4 is arranged transversely and slides laterally with the long side clamping seat 2. The core clamping drive rod 43 is arranged vertically. The core clamping cylinder 41... Located below the core clamping drive rod 43 and driving the core clamping drive rod 43 to move vertically, the core clamping transmission rod 42 is set horizontally, with one end hinged to the long side clamping seat 2 and the other end hinged to the upper end of the core clamping drive rod 43. The core clamping cylinder 41 drives the clamping drive rod to move upward, thereby driving the long side clamping seat 2 to move horizontally closer to the core clamping slide 3. Since the clamping slide strip 31 is fixed to the long side clamping seat 2, the core located in the core clamping slide 3 is locked between the clamping slide strips 31 on both sides during clamping, ensuring stable clamping.

[0032] like Figure 4 , 5As shown, the clamping worktable 1 is laterally slidably equipped with a long-side changing slide 44 for mounting the core clamping cylinder 41. The first long-side changing fixing seat 45 mentioned below is equipped with a changing guide groove 451 for the long-side changing slide 44 to slide laterally. The first long-side changing fixing seat 45 is fixedly installed on the other side of the long-side changing slide 44 opposite to the core clamping slide 3 on the clamping worktable 1. A first long-side quick changing block 46 is provided between the long-side changing slide 44 and the first long-side changing fixing seat 45. A first core quick changing cylinder 47 is fixedly installed on the first long-side changing fixing seat 45 to drive the long-side changing slide 44 to slide laterally and clamp the first long-side quick changing block 46 between the long-side changing slide 44 and the first long-side changing fixing seat 45. Activating the first core quick changing cylinder 47 can quickly change the core. By replacing the first long-side quick-change block 46 with one of different thicknesses, the distance between the long-side quick-change slide 44 and the core clamping slide 3 is adjusted, thereby adjusting the distance between the two long-side clamping seats 2, i.e., adjusting the distance between the clamping slide strips 31 fixed to the long-side clamping seats 2, thus adapting to cores of different thicknesses and realizing quick and accurate change of the clamping device, greatly improving change efficiency. In addition, since this side has a core clamping mechanism, the first long-side quick-change block 46 uses the core clamping mechanism as a change transition component, while the other side does not have a core clamping mechanism. The second long-side quick-change block 52 mentioned below acts directly on the long-side clamping seat 2. In order to ensure change stability, the first long-side quick-change block 46 and the second long-side quick-change block 52 each have two sets and are distributed on the longitudinal sides of the long-side clamping seats 2 on different sides.

[0033] like Figure 6 As shown, a long-side changing track 5 is provided on the other side of the core clamping slide 3 relative to the core clamping mechanism on the clamping worktable 1. The long-side changing track 5 is arranged laterally and slides laterally with the long-side clamping seat 2. A second long-side changing fixing seat 51 is fixedly provided on the other side of the long-side clamping seat 2 relative to the core clamping slide 3 on the clamping worktable 1. A second long-side quick changing block 52 is provided between the second long-side changing fixing seat 51 and the long-side clamping seat 2. A driving long-side clamping block is fixedly provided on the second long-side changing fixing seat 51. The seat 2 slides laterally and clamps the second long-side quick-change block 52 between the long-side clamping seat 2 and the second long-side quick-change fixed seat 51. The second core quick-change cylinder 53 is activated, which can quickly replace the second long-side quick-change block 52 of different thicknesses, thereby adjusting the distance between the two long-side clamping seats 2, that is, adjusting the distance of the clamping slide strip 31 fixed to the long-side clamping seat 2, so as to adapt to cores of different thicknesses, realize the quick and accurate change of the clamping device, and greatly improve the change efficiency.

[0034] like Figure 1As shown, it also includes a core preparation slide 6 located in front of the core pressing slide 3 and for longitudinal sliding of the core. The core preparation slide 6 includes preparation slide strips 61 located on both sides laterally. The pressing worktable 1 is provided with preparation change rails 63 for lateral sliding of each preparation slide strip 61. A synchronous change arm 62 is provided between the preparation slide strip 61 and the same side long side pressing seat 2 to fix the two. The core preparation slide 6 is used to place the core waiting to be pressed. The synchronous change arm 62 fixes the preparation slide strip 61 and the same side long side pressing seat 2. When the long side pressing seat 2 is changed, the preparation slide strip 61 is changed synchronously, which simplifies the change steps and the change structure and greatly improves the change efficiency.

[0035] like Figure 1 , 7 As shown, it also includes short-side clamping seats 7 located on both sides of the core clamping slide 3 longitudinally and short-side clamping mechanisms disposed on the short-side clamping seats 7. The short-side clamping mechanism includes a short-side clamping arm 71, a short-side transmission rod 72, a short-side transmission guide groove 73, a short-side transmission rod 74, a short-side drive rod 75, and a short-side drive cylinder 76. The short-side clamping arm 71 is arranged longitudinally, and the end of the short-side clamping arm 71 facing the core clamping slide 3 serves as the short-side clamping end 7 of the clamping claw teeth. 11. The end facing away from the core clamping slide 3 serves as the short side force-bearing end 712. The short side transmission rod 72 is arranged longitudinally and located below the short side clamping arm 71. Above the end of the short side transmission rod 72 facing the core clamping slide 3, a short side transmission hinge seat 721 is provided, which is hinged to the short side clamping arm 71. The short side transmission guide groove 73 is arranged longitudinally on the short side clamping seat 7 and slides longitudinally with the short side transmission rod 72. The short side drive rod 75 is arranged vertically and located on the short side. On the opposite side of the core clamping slide 3, opposite to the transmission rod 72, the short-side drive cylinder 76 is fixed to the short-side clamping seat 7 and drives the short-side drive rod 75 to move vertically. The short-side transmission rod 74 is arranged longitudinally, with one end hinged to the short-side transmission rod 72 and the other end hinged to the upper end of the short-side drive rod 75. When the short-side drive rod 75 rises, the upper end presses against the short-side force-bearing end 712. When the core reaches the core clamping slide 3, the short-side drive cylinder 76 drives the short-side drive rod 75 to rise. As the short-side drive rod 75 rises, the short-side transmission rod 72 drives the short-side clamping arm 71 to gradually approach the core clamping slide 3 longitudinally. The short-side clamping end 711 bends the claw teeth towards the water chamber. Then, the short-side drive rod 75 continues to rise, and the upper end of the short-side drive rod 75 presses against the short-side force-bearing end 712, causing the short-side force-bearing end 712 to rise while the short-side clamping end 711 presses down, pressing the claw teeth downward, thus completing the automatic clamping of the short-side clamping arm 71. The above structure has the following advantages: the short-side drive rod 75 can be driven to rise linearly by a single drive source, which can realize the continuous clamping action of the short-side clamping end 711 on the claw teeth, avoiding the assembly interval caused by dual drive sources, greatly improving assembly efficiency and product quality. At the same time, it simplifies the drive structure, making the equipment structure more streamlined.

[0036] like Figure 7 As shown, it also includes a short-side longitudinal shift seat 77, a short-side longitudinal shift track 78, a short-side longitudinal shift motor 79, a short-side transverse shift track 11, and a short-side transverse shift cylinder 12. The short-side longitudinal shift track 78 is fixed longitudinally to the short-side longitudinal shift seat 77 and slides longitudinally with the short-side clamping seat 7. The short-side clamping seat 7 is provided with a short-side longitudinal shift nut seat 70. The short-side longitudinal shift motor 79 is fixed to the short-side longitudinal shift seat 77 and drives a short-side longitudinal shift screw 791 with a threaded engagement with the short-side longitudinal shift nut seat 70. The short-side longitudinal shift motor 79 and the short-side longitudinal shift screw 791 are arranged parallel to each other and are driven by a synchronous pulley 792 and a synchronous belt. The short-side transverse shift track 11... The short side is fixed to the pressing worktable 1 laterally and slides laterally with the short side longitudinal sliding seat 77. The short side transverse sliding cylinder 12 is fixed to the pressing worktable 1 and drives the short side longitudinal sliding seat 77 to slide laterally. The short side longitudinal sliding track 78 and the short side longitudinal sliding motor 79 cooperate to realize the automatic longitudinal movement of the short side pressing mechanism. The short side transverse sliding track 11 and the short side transverse sliding cylinder 12 cooperate to realize the automatic transverse movement of the short side pressing mechanism. This allows the short side pressing mechanism to automatically exit the core pressing slide 3 when not being processed and automatically enter the core pressing slide 3 when being processed. This avoids obstructing the core pushing while realizing the automatic pressing of the short side, making the equipment run more smoothly.

[0037] like Figure 8 As shown, it also includes a core transition slide 8, a transition slide bar transverse sliding seat 9, a transition slide bar transverse sliding track 91, and a transition slide bar transverse sliding cylinder 92. The transition slide bar transverse sliding track 91 is fixed laterally to the clamping worktable 1 and is located on the other side of the core clamping slide 3 opposite to the short side longitudinal sliding seat 77. The transition slide bar transverse sliding seat 9 and the transition slide bar transverse sliding track 91 slide laterally. The transition slide bar transverse sliding cylinder 92 is fixed to the long side clamping seat 2 and drives the transition slide bar transverse sliding seat 9 to slide laterally. The core transition slide 8 is located on both longitudinal sides of the core clamping slide 3 and allows the core to slide longitudinally. The core transition slide 8 includes core transition slide bars 81 located on both sides laterally, one of which is a core transition slide bar. The transition slide bar 81 is fixed to the short side longitudinal shift seat 77, and the core transition slide bar 81 on the other side is fixed to the transition slide bar transverse shift seat 9. The core transition slide bar 8 is used to transition the core from the previous station to the core pressing slide bar 3 or to transition the core from the core pressing slide bar 3 to the next station. The short side longitudinal shift seat 77 and the transition slide bar transverse shift seat 9 control the transverse movement of the core transition slide bar 8 to avoid the core transition slide bar 8 obstructing the short side pressing mechanism from entering the core pressing slide bar 3. In addition, the short side longitudinal shift seat 77 uses its transverse movement function, and the transition slide bar transverse shift seat 9 uses the shape-changing function of the long side pressing seat 2 to realize the automatic shape-changing of the core transition slide bar 8, simplifying the shape-changing steps and shape-changing structure, and greatly improving the shape-changing efficiency.

[0038] like Figure 9As shown, it also includes a water chamber clamping mechanism, which includes a water chamber clamping platform 10 located above the clamping workbench. Below the water chamber clamping platform 10 is a fixture mounting base 101 for installing the water chamber contouring fixture. The water chamber clamping platform 10 is equipped with multiple lifting guide sleeves 102, two lifting nuts 103, and a water chamber clamping motor 104. The fixture mounting base 101 is vertically provided with lifting guide rods 1011 that slide and cooperate with each lifting guide sleeve 102. The two lifting nuts 103 are rotatably mounted on both longitudinal sides of the water chamber clamping platform 10. Each lifting nut 103 is coaxially fixed with a lifting synchronous wheel 1031. The fixture mounting base 101 is vertically provided with screws that screw onto each lifting nut 103. The lifting screw 1012 is fitted with a synchronous belt, and the water chamber pressing motor 104 drives the pressing synchronous wheel 1041, which drives the lifting synchronous wheel 1031 to rotate synchronously via a synchronous belt. The water chamber pressing motor 104 drives the lifting synchronous wheel 1031 to rotate synchronously via the pressing synchronous wheel 1041 and the synchronous belt, thereby realizing the dual-point lifting structure of the tooling mounting base. This makes the lifting of the water chamber contour tooling installed on the tooling mounting base more precise and stable. It can also adapt to water chambers of different heights by adjusting the lifting height, and adopts an automatic adjustment structure to realize digital rapid changeover. To clearly show the structure, the synchronous belt that constitutes the transmission cooperation between the lifting synchronous wheel 1031 and the pressing synchronous wheel 1041 is hidden. The synchronous belt is an existing component and does not affect the understanding of the structure.

[0039] In addition, all electrical control components work together under the unified control of the equipment's controller. At the same time, to ensure the accuracy of the above-mentioned structural movements, all motors are servo motors and cylinders are servo cylinders.
